DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an engine test run method, and more particularly to an engine test run method in which an assembled engine can be directly carried into a test run device body via a transfer device without using a pallet.

[0002]

2. Description of the Related Art Conventionally, in order to supply a user with a high-quality and highly reliable engine in an engine production line, engine trials have been performed on all engines especially in a diesel engine. In this type of test run device, the engine after assembly is transferred and set on a pallet using a crane, etc., and the piping and
After performing the wiring work, it is transported to the test run device main body side.

However, the pallet method has to rely on manual connection between the engine and the pallet, requires special piping equipment for the pallet itself, and requires a large number of pallets, which is proportional to the size of the engine. As a result, the size of the pallet increases, and if it is used for a large truck-type diesel engine, the size of the pallet increases. Further, basically, in a system using a pallet, it is necessary to provide a transfer device for pallet circulation, which leads to an increase in equipment cost and an increase in installation area.

[0004] In order to solve such a drawback, the present applicant has effectively utilized a front mount and a rear mount provided on an engine mounting portion in Japanese Utility Model Laid-Open No. 1-168845, and used a test apparatus main body side. Is provided with a mount receiving portion for supporting the mount, an engine positioned on the assembly table is positioned and installed on the mount receiving portion via a crane, and then a space between the engine and a dynamometer for measuring engine performance is installed. It is composed. First, the movable bearing 6 will be described with reference to FIG.
With the spline of the connecting shaft 9 of the flexible shock-absorbing joint 7 retracted toward the dynamometer 2 along the dynamometer 2, the engine is suspended from the assembly table by a crane and When the movable bearing 6 is shifted toward the flywheel 51 along the guide rails after fixing the front and rear mounting portions on the mount receiving portion, the tip of the connecting shaft 9 is inserted into the spline attached to the flywheel 51 side. and Sutatamo - the connecting shaft splines and the flywheel 51 side of the spline with the rotation by turning gearing which rotates slow the motor 50 can be smoothly fitted, while continuing rotating the turning gearing starter A test run of the engine is performed by rotating the engine.

[0005]

However, in order to adopt a configuration in which an engine located on an assembly table is positioned and installed on the mount receiving portion via a crane, manual transportation is required. Precise positioning is not possible.

Therefore, the present inventor further studied and used a drive roller which can be lifted down at a predetermined position in order to perform positioning without using the crane, and arranged the drive roller between the assembly line and the test operation device main body. Then, the engine mounted on the unmanned carrier of the assembly line is selectively carried into the drive roller side, and after being transported by the drive roller to a predetermined position for trial operation, the roller is lifted down and The study also proposes a method of positioning and fixing the mount on the mount receiver. (Actual opening 1-12964
No. 4)

However, the above method has a disadvantage that it cannot cope with a change in the engine model. That is, in order to enable unmanned operation in the above system, connection of water supply, refueling, exhaust, and other piping systems is automated. It is also necessary to change the positioning position of the engine, but this is difficult with the above prior art. Further, the flexible shock-absorbing joint is moved to the engine side while rotating, and the spline shaft arranged on the joint side is fitted into the center female spline of the clutch disc, thereby connecting the power system and the engine. At this time, if the engine installation position fluctuates at this time, the spline shaft may come into contact with the engine when the spline shaft is inserted, or may not be sufficiently inserted.

The present invention has been made in view of the above-mentioned drawbacks of the prior art, and has as its object to provide an engine test run method capable of performing accurate positioning even when the engine type is changed unattended.

[0009]

According to the present invention , the use of a drive roller means capable of lifting down is the same as the above-mentioned examination technique, but the present invention enables accurate positioning of piping even when the engine model changes. to a portion of the piping system connected to the engine, after being repositioned to correspond to the engine model, the point for connecting the piping system to the engine first
The feature of. A second feature is that a clutch disc is attached together with a flywheel in an assembly line process before being carried into the drive roller means , and a flexible spline is provided using a female spline provided in a center hole of the clutch disc. The point lies in connecting the spline to the connection shaft (male) on the buffer joint side.

In this case, the diameter of the center female spline of the clutch disk may differ depending on the model. Therefore, the connecting spline on the flexible buffer joint side is not necessarily fixed, and the female spline diameter on the flexible buffer joint side is not necessarily fixed. previously formed a spline may be configured such that the free end side female spline plugging advance a connecting shaft splines with fitted possible diameter in the center a female spline of the clutch disk, and the center of the clutch disc side It may be configured to be inserted into the female spline in advance and then connected.

In this case, in order to enable accurate insertion of the spline shaft even when the engine model is changed, the amount of movement of the spline shaft provided on the side of the flexible shock-absorbing joint is determined by the amount of movement of the engine. the regulating means can regulate to switched selectively in correspondence to the model provided, Ru switches the movement restricting position before movement of at least the spline shaft
It is desirable to configure as follows. Incidentally selection has the same effect even by performing position regulation of the engine front end instead of the restriction of the movement of the spline shaft side in the case of the prior SL drive roller means according to the stop position corresponding to engine model It is also possible to arrange a stopper means which can be selectively switched, and to selectively switch the positioning position by the stopper means.

Each of the lapping test device R and the hot test device H has the configuration shown in FIG. 1, and an engine carrier D is provided around the engine installation section and the dynamometer 2.
It is surrounded by a soundproof room B provided with an opening / closing door on the side. In the assembly line, a clutch disc 52 is attached together with the flywheel 51 to the engine 10 after the assembly is completed .
It is. (Note that in this embodiment, the spline shaft 9 is
A description will be given of a case in which
However, the spline shaft 9 is attached to the clutch disc 52 in advance.
You may leave it. Then, the spline shaft corresponding to the clutch disk 53 on the engine side is inserted into the clutch disk 52 in advance. The engine transport trolley D can carry two engines 10, and travels unmannedly on a rail A facing the cold test device C and the lapping test device R. The reason why two engines can be mounted is to replace the engine before the test with the engine after the test, and one engine is mounted when moving between the test devices. Then, the engine 10 located on the engine carrier D is randomly introduced into the cold test device C side and the lapping test device R side one by one to terminate a predetermined test, and then the two tests are terminated. After returning to the delivery trolley D side, it is sent to the transfer line A1 and waits for the hot test apparatus H to become empty. When the hot test device H is empty, the hot test device H is mounted on the engine carrier D on the side of the hot test device H, and is conveyed to the hot test device in the same manner.

Next, the operation of loading and connecting the engine 10 in each of the test lines, particularly in the lapping test apparatus R, will be described in detail. First, the piping system 60A-6
Cylinder moving in 0D engine movement direction (方向 direction)
61 by actuating the after positioning displace corresponding to the engine type, piping system by utilizing the other cylinders 62, 63 60
A to 60D are retracted from the moving space of the engine.
The mounting receptacle 15 and 16 is likewise pneumatic or allowed to retract from the moving space of more engine oil pressure silicon <br/> down da. Further, the spline shaft 9 is also replaced according to the corresponding engine model. When the engine 10 after the end of the cold test is called from the assembly line after the completion of the above-mentioned setup, the carrier D carrying the one engine 10 arrives at the facing position, and then the door of the soundproof room B is opened. After the engine 10 after the lapping test is transferred to the carrier D, the carrier D is shifted and the engine 10 before the lapping test is introduced into the test apparatus by using the drive roller conveyor 12, and the soundproof room Close B's door.

Next, the first drive roller conveyor 12 is moved to the second drive roller conveyor 13 and the stopper 17 is moved.
By at the position regulated stage, pneumatic and hydraulic after the Cylinders mount receiving portion 15, 16 than <br/> was returned to the normal position, the air pressure and the with the lowering hydraulic cylinder 14 second
The drive roller conveyor 13 is lifted down, and the mount portion 10a of the engine 10 is placed on the front and rear mount receiving portions 15 and 16 supporting the engine 10, and then, the clamp device 18 is lowered and the engine 10 is lowered. 10 is clamped from above.

Next, after the actuator of the regulating mechanism 19 of the movable bearing 6 is switched by rotating forward or backward in accordance with the type of engine, the air pressure of the inertial force applying means and the piston 41 of the hydraulic cylinder 40 are raised. While the claw 42 at the tip of the piston 41 is engaged with the teeth 4a of the sprocket 4,
The sprocket 4 is rotated. At the same time, when the movable bearing 6 is advanced by the pneumatic and hydraulic cylinders 11, the spline shaft 9 after the application of the inertial force becomes completely free movement. The end of the spline 52a contacts the end of the spline 52a, and the rotational speed is rapidly reduced by the resistance at the time of contact.
The spline shaft 9 is provided with the female spline 5 on the engine 10 side because the two are formed so as to be shifted from each other in the axial direction.
2a is smoothly inserted.

Immediately after the insertion, the rotational movement is stopped by the load torque on the engine 10 side, and the tooth cross-sectional shape of the spline shaft 9 is reduced, so that a clearance is provided between the spline shaft 9 and the female spline 52a in the circumferential direction. Therefore, a smooth insertion can be achieved even if there is misalignment or runout between the engine 10 and the spline shaft 9. When the spline shaft 9 is inserted into the center female spline 52a of the clutch disc 52, the support portion 91 at the tip end is inserted.
There wherein is supported by a bearing 51 a of the flywheel 51, the flexible buffer catch becomes two point support between 7 are possible runout suppression. Further, since the side surface of the support portion 91 is formed in an R (curve) shape, even if the center run-out occurs, the support portion 91 can be swung about the support portion 91 to prevent occurrence of galling or the like. Can be prevented. The clutch disk 5
Since the ball plunger 93 is attached to the bottom of the tooth surface of the spline shaft 9 at a portion where the spline shaft 9 is fitted to the second center female spline 52a, the spline shaft 9 can be prevented from coming off and a torque fluctuation peculiar to the diesel engine itself can be dealt with.

When the support portion 91 at the end of the spline shaft 9 reaches the bearing 51a hole of the flywheel 51, the base 69 of the movable bearing 6 comes into contact with the regulating device main body 192, whereby the advance is regulated, and the pneumatic pressure is reduced. And the hydraulic cylinder 11 is stopped.

After the connection with the engine 10 is completed, the pneumatic and hydraulic cylinders 61 to 63 are appropriately operated to operate the hydraulic outlet pipe 60A, the supply / drainage pipes 60B and 60C, and the exhaust pipe 60D. After the connection is made, predetermined water supply / drainage and exhaust hydraulic pressure are taken out, and the engine 10 is started while the starter motor 50 is driven to operate the engine 10 at a low speed. After the test operation and adjustment of the engine 10, the operation of the test engine is performed by retreating the movable bearing 6, releasing the clamp of the engine 10 by raising the clamp device 18, lifting the drive roller conveyor 13, and the like. 10 is exchanged, and the above operation is repeated.

[0029]

As described above, according to the present invention, accurate positioning can be performed without using a crane or the like, even when the engine model is changed. Also the engine side female spline according to the present invention, also, the female spline coupled to contact the hand dynamometer side, it is possible to inserted smoothly fitting the male spline, thereby together with prevention of the spline of chipping or breakage, An unmanned engine test run device can be achieved more easily. Even in the case of large engines track such, according to the present invention, also can be adequately cope with the torque fluctuations over a wide range from fast load to low load. And so on.
