Description

Detailed Description of the Invention (Industrial Field of Application) This invention involves putting work materials such as abrasives or cutting materials and workpieces into a rotating storage tank, and rotating the storage tank around its axis. The present invention relates to a polishing apparatus that performs polishing such as deburring and deburring parts.

(Prior Art) Conventionally, as shown in FIG. 5, for example, in this type of polishing apparatus, a lid body 52 is detachably provided around the periphery of a cylindrical or polygonal cylindrical storage tank 51. Processed materials and workpieces were taken in and out of the storage tank 51. Reference numerals 53 denote a pair of rotating disks that are provided on both sides of the storage tank 51 and hold the storage tank 51 in a rotatable manner.

(Problems to be Solved by the Invention) In order to uniformly process the workpiece placed in the storage tank, the workpiece and the workpiece must move uniformly within the storage tank. However, as described above, since the conventional polishing apparatus has the lid 52 around the periphery of the storage tank 51, the presence of seams and the like on the inner peripheral surface of the storage tank 51 is unavoidable, resulting in a discontinuous surface. If the workpiece is stuck at the joint, uneven machining may occur, or liquid may leak from the joint due to rotational centrifugal force, or the workpiece may become deformed in some cases. There was a drawback that defective products were produced.

The object of the present invention is to eliminate such conventional drawbacks and provide a polishing apparatus that does not produce defective products due to uneven processing or deformation.

(Means for Solving the Problems) In order to solve the above-mentioned problems, a polishing apparatus according to the present invention has a storage tank that accommodates workpieces and processed materials in a tank holding means that is rotatably installed on a shaft. In a polishing apparatus, the storage tank is rotatably driven to revolve around the rotation axis of the tank holding means by automatically driving the storage tank relative to the tank holding means, The tank holding means is constituted by a pair of face plate-shaped turrets mounted oppositely to the rotating shaft, and a cylindrical turret having a cover that can be opened and closed at both ends and having no dividing structure in the circumferential direction is provided between the two turrets. The storage tank is rotatably installed so as to protrude from the surface of the turret, with one end of the storage tank serving as an input port and the other end serving as a discharge port. It is pivoted so that it can be tilted toward the discharge port, and is equipped with an inclination angle adjustment function.

(Function) When the workpieces and processing materials are placed in the storage tank and the storage tank is rotated and revolved, the inner peripheral surface of the storage tank is formed as a continuous surface, so the workpieces and processing materials are The materials do not get stuck in the storage tank, they are always mixed uniformly, and the workpiece is processed homogeneously. Moreover, the lid body is attached to the end of the storage tank in the direction of the rotation axis, and one side is the input port. , the other is provided as a discharge port, from which the workpieces, etc. are put into and discharged from the storage tank, respectively, and the rotation axis of the tank holding means can be tilted toward the discharge port via the revolution axis tilting means. Because of this, it is possible to automate the loading and unloading and to create continuously operating unmanned processing equipment.

(Example) An example of the present invention will first be described based on FIGS. 1 and 2.

and a pair of pillars erected at both ends thereof, and both ends of the shaft 3 are supported between the tops of these pillars. A pair of turrets (driving turret 4, driven turret 5), which are tank holding means, are mounted on the shaft 3.
They are rotatably supported at intervals. A motor 6 is installed on the base 1, and a drive belt 8 is passed around the outer circumference of the drive turret 4 and a pulley 7 attached to its output shaft. It is designed to rotate around the center. Note that instead of such a belt drive, a chain, gears, or other drive means may be used.

The two turrets 4, 5 each have a pair of holes 9...
Two cylindrical storage tanks 10 and 1 are provided with holes, and the tanks for storing the workpiece and the processing material are longer than the diameter.
0a and 10b are rotatably fitted into the holes 9. In this way, the two storage tanks 10a, 1
0b are rotatably held near both ends by turrets 4 and 5, one storage tank 10a is provided parallel to the axis 3, and the other storage tank 10b is provided at an angle with respect to the axis 3. There is. Such a storage tank 1
The mounting angle of 0 can be freely selected by changing the positions of the holes 9 in the turrets 4 and 5, and the most convenient inclination angle can be selected depending on the processing purpose.

Reference numeral 11 denotes a flange protruding from the storage tank 10, which loosely abuts on the turrets 4 and 5 and closes the storage tank 10.
The axial direction of the alloy is regulated. Also, each storage tank 1
Sprockets 12 and 13 are fixed to each of the sprockets 0a and 10b and the drive turret 4, and a chain 15 is wound around these sprockets 12 and 13. When the drive turret 4 rotates, these sprockets 12 and 13 The storage tanks 10a and 10b rotate (rotate) via the chain 15. The number of rotations (autorotation) of each storage tank 10a, 10b can be freely selected by changing the number of teeth of each sprocket 12, 13, and the most convenient number of rotations can be selected depending on the processing purpose etc. Alternatively, the rotation of the storage tank 10 may be driven by another motor or the like.

As described above, the storage tank 10 is formed into a cylindrical shape with a dimension longer than the diameter, but both ends thereof, that is, both ends in the direction of the rotation axis, are open so that the workpieces and materials to be processed can be input. Alternatively, when one side of the discharge port 16 is used as an input port, the other side is formed as a discharge port. On the other hand, no openings or the like are formed in the circumferential portion of the storage tank 10, and the inner circumferential surface thereof is formed of a continuous surface.

Each opening 16 formed at the end of the storage tank 10 is provided with a lid 17 that can be opened and closed. This lid body 17 is screwed to the storage tank 10 by a hinge 18 protruding from the side of the end of the storage tank 10 so that the storage tank 10 can be opened and closed. The portion 16 can be closed with strong force.

When processing a workpiece using the above-described embodiment configured in this way, first open the lid 17 at one end of the storage tank 10, close the lid at the other end, and then close the lid 17 at the open end. A processing material such as an abrasive material, an abrasive material, or a grinding blade, and a workpiece are introduced into the storage tank 10 from the section 16 . After all the lids 17 are closed, when the motor 6 is rotated, the driving turret 4 is rotated, whereby the storage tank revolves around the shaft 3, and the driven turret 5 also rotates following this. At the same time, the storage tank 10 is connected to the turrets 4 and 5 via the sprockets 12 and 13 and the chain 15.
