Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a component holding jig that can be used in an automatic machine that automatically assembles components.

2. Description of the Related Art Conventionally, in the case of assembling parts, as shown in FIG. 11, a method of pressing a part 2, for example, a partition plate on a case 1, for example, a tuner case by a cylinder 18, or a case 1 as shown in FIG. There was a method of sandwiching the component 2 with the leaf spring 20.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in the method of pressing with the cylinder 18 as shown in FIG. 11, a drive source is required and the device becomes large. In the method of sandwiching with the leaf spring 20 as shown in FIG. 12, it is difficult to attach the leaf spring 20, and the elastic force of the leaf spring 20 becomes weak immediately. Further, when soldering or the like is performed without pressing the parts, the parts float as shown in FIG.

The present invention is intended to solve such a conventional problem, is easy to install, is compact, and can always hold components at two places with a constant force, and can fix the lever with one touch. The purpose is to provide a device.

Means for Solving the Problems The component pressing jig of the present invention includes a lever having a protrusion that presses a component at two locations, a pin attached to the lever, a bar for rotatably mounting the pin, and a spring for pulling one end of the bar. , A block that locks the other end of the bar, and a ring that fixes the other end of the bar locked to the block to the block with one touch.

Action According to the component holding jig of the present invention as described above, the component can be closely attached to the case and soldered and screwed together without floating. Moreover, since the parts are pressed at two places, one side of the parts does not float.

Therefore, according to the present invention, it is possible to mount the parts accurately and quickly without floating.

Embodiment A component holding jig according to an embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a plan view of a component holding jig according to an embodiment of the present invention, and FIGS. 2 to 5 are sectional front views of the same portion showing movements of the respective components when holding the components in a case, and FIG. , FIG. 7 is a partial front view showing a state where parts are attached to the case, and FIG. 8 is
a and b are partial plan sectional views and front views of the ring mounting portion showing a state before fixing the bar, and FIG. 9 a and b are partial plan sectional views and front view showing the state in which the bar is fixed, and FIG. a
˜c are drawings of the ring alone.

In FIG. 1, reference numeral 1 is a case, for example, a tuner case, 2 is a component, for example, a partition plate, 3 is a lever for pressing the component 2, 4 is a pin for allowing the lever 3 to rotate freely, and 5
Is a bar on which the lever 3 is rotatably attached by a pin 4 and which can be rotated up and down, right and left, 6 is a pin provided at one end of the bar 5, and 7 is a block for locking one end of the bar 5. Thus, the bar 5 has a cutout portion into which one end of the bar 5 is inserted.
8 is a hole for preventing slippage provided in the block 7 for inserting the pin 6, 9 is a fulcrum pin for rotatably supporting the bar 5, and 10 is a rotatably mounted bar 5 by the fulcrum pin 9, Further, a shaft for pulling the bar 5 toward the plate 15 by a spring to be described later, 11 in FIG. 2 is the above-mentioned spring, 12 is a nut for mounting this spring and a block, and 13 and 14 are fixing the case 1 to the plate 15. Mounting block for
16 is a partition plate, and 17 is a ring for fixing the bar 5 to the block 7. The elliptical ring-shaped portion 17a, the standing portion 17b standing upright from a part of the ring-shaped portion 17a, and the standing portion 17b are continuous. Arc-shaped portion 17c formed by the above, a flat portion 17d for vertical position determination formed continuously at the other end of the arc-shaped portion 17c
And a positioning cut-and-raised portion 17e formed so as to project inward on a part of the ring-shaped portion 17a.

In the above structure, the case 1 is attached to the attachment blocks 13 and 14, and the part 2 is attached to the case 1. On the other hand, the ring 17 is attached to the block 7, and the flat portion 17d is attached to one end of the ring 17 so that the flat portion 17d is located in the cutout portion of the block 7 (see FIG. 8). Then, the bar 5 is rotated about the pin 9 as a fulcrum in the direction of the arrow shown in FIG. Then, the lever 3 rotatably attached to the bar 5 by the pin 4 presses the component 2. Two protrusions on lever 3
There are 3a and 3b. First, the protrusion 3a hits the component 2 and the lever 3
Rotates around the pin 4, and the protrusion 3b hits the component 2 to press the component 2 at two places.

When the bar 5 is further rotated, the shaft 10 is pulled upward against the force of the spring 11 via the pin 9 with the lever 3 as a fulcrum. When the bar 5 is further rotated, the state shown in FIG. 3, that is, one end of the bar 5 contacts the case 1.
At this time, the block 7 for stopping the bar 5 is tilted so as not to get in the way. Next, as shown in FIG. 4, when the block 7 is erected straight and the force applied to the bar 5 is removed, the bar 5 moves to the opposite side of the arrow in FIG. Is rotated, and one end of the bar 5 enters the cutout portion of the block 7 and the pin 6 is fitted into the hole 8 of the block 7 as shown in FIG. By further moving the ring 17 from the state shown in FIG. 8 to the state shown in FIG. 9 in the direction of the arrow, the arc-shaped portion 17c of the ring 17 becomes a bar at the notch as shown in FIG. It is located below 5 and functions as a stopper so that the bar 5 does not descend. As a result, the bar 5 can be fixed so as not to come out of the block 7, and the component 2 can be reliably pressed against the case 1 by the lever 3, so that the component 2 does not float above the case 1 as shown in FIG. It can be securely fixed as shown in FIG. The ring 17 does not easily slide left and right due to the presence of the cut and raised portion 17e.

As described above, according to this configuration, the component 2 can be reliably fixed to the case 1 by rotating one bar 5 and locking it on the block 7 and locking it by the ring 17. Also, if this jig is run without assembling the component 2, the bar 5
Although there is a risk that it will come off easily from the block 7 and be caught by a component on the conveyor, in the present configuration, the bar 5 can be reliably fixed to the block 7 by the ring 17, so the above-mentioned fear can be eliminated.

EFFECTS OF THE INVENTION As described above, according to the component pressing jig of the present invention, it is easy to mount, is compact, and can always hold a component at two places with a constant force. Even if it is, the bar is fixed and there is no fear of it coming off, which is very effective for improving workability.
