Description

  The present invention relates to a barrel polishing container jig, a barrel polishing apparatus, and a barrel polishing method used when barrel-polishing a plurality of different parts.

  In barrel polishing, a polishing tank in which a workpiece to be polished and a polishing agent are charged is vibrated or rotated, so that the polishing agent and the workpiece are relatively moved by vibration force, rotational force, or centrifugal force. This is a technique for polishing a workpiece by friction generated between the workpiece and an abrasive. Such barrel polishing includes removal of burrs present on the workpiece, polishing of the surface of the workpiece, roughening of the surface of the workpiece, or removal of the surface oxide film or painted surface of the workpiece. It is applied for various purposes.

  In barrel polishing, after the polishing process is completed, the workpiece is taken out from the abrasive in the polishing tank. Here, when the workpiece is small, when the workpiece is taken out from the abrasive in the polishing tank, it is necessary to select the workpiece buried in the abrasive. The smaller the size of the workpiece relative to the size of the polishing tank, the longer it takes to select and remove the workpiece buried in the abrasive. In some cases, the workpiece cannot be selected from the abrasive, and the workpiece may remain in the abrasive in the polishing tank.

  When processing parts of various shapes at the same time using the same polishing tank, especially when large parts and small parts are mixed, the shape and material of the abrasive suitable for the large parts and the small parts The shape and material of the abrasive that conforms to may vary. In this case, it is necessary to polish each part in a separate batch with a combination of the part and an abrasive suitable for the part. In barrel polishing, an abrasive suitable for the size, shape and material of the workpiece is used. For this reason, the operation | work which changes the abrasive | polishing agent in a grinding | polishing tank to the thing suitable for each component for every batch is needed.

  In response to such a problem in barrel polishing, Patent Document 1 discloses that a small-diameter shaft body through which a ring-shaped workpiece is freely inserted, and a workpiece that is provided at both ends of the shaft body and is inserted through the shaft body. There is disclosed a barrel polishing jig that includes a regulating member that regulates the shape of the ring-shaped workpiece and other shapes of workpieces inserted through the shaft.

Japanese Patent Laid-Open No. 60-062454

  However, according to Patent Document 1, the workpiece that can use the barrel polishing jig is limited to a workpiece having a shape that can be inserted into the shaft, and furthermore, only one type of abrasive can be used. However, there is a problem in that a plurality of workpieces having different sizes, shapes, or materials cannot be simultaneously polished with an abrasive suitable for each workpiece.

  The present invention has been made in view of the above, and an object of the present invention is to obtain a barrel polishing container jig that enables a plurality of types of workpieces with different abrasives to be polished in the same batch. To do.

  In order to solve the above-described problems and achieve the object, a barrel polishing container jig according to the present invention includes a first abrasive used for polishing a first workpiece and a first workpiece in a barrel polishing apparatus. A barrel polishing container jig that is put into the polishing tank when the first workpiece is polished. The barrel polishing container jig is a hollow container that can be divided into a plurality of divided parts. The first workpiece is different from the first workpiece in at least one of the size, shape, and material. Unlike the abrasive, a second abrasive used for polishing the second workpiece is enclosed inside.

  According to the present invention, there is an effect that a barrel polishing container jig capable of performing polishing processing of a plurality of types of workpieces having different compatible abrasives in the same batch is obtained.

Embodiment FIG. 1 is a schematic diagram showing a barrel polishing apparatus 1 according to an embodiment of the present invention. The barrel polishing apparatus 1 is a vibrating barrel in which a polishing process using a frictional motion between a workpiece and an abrasive is performed due to a relative motion difference between the workpiece and the abrasive in the barrel tank caused by vibration of the polishing tank. It is a polishing apparatus. The barrel polishing apparatus 1 is a barrel polishing apparatus that can perform polishing processing on workpieces of different sizes individually and simultaneously using an abrasive suitable for each workpiece.

  In the following, a case will be described where two types of workpieces having different sizes are subjected to a polishing process simultaneously. That is, the case where the first workpiece 21 having a relatively large size and the second workpiece 22 having a relatively small size are simultaneously polished in the barrel polishing apparatus 1 will be described below. In FIG. 1, the size of the abrasive is enlarged and shown larger for easy understanding.

  The barrel polishing apparatus 1 includes a polishing tank 11 having an upper opening, an upper housing 12 on which the polishing tank 11 is placed, and a pedestal 14 that supports the upper housing 12 via a spring 13.

A rotating shaft 15 having an unbalanced weight 17 fixed to a part thereof is fixed to the bearing 16 via the bearing 16 so as to be rotatable. The rotating shaft 15 is fixed to the pedestal 14 and connected to a motor 18 that rotates the rotating shaft 15.

  As shown in FIG. 1, the polishing tank 11 includes a first workpiece 21 having a relatively large size among two types of workpieces having different sizes that are simultaneously subjected to the polishing process in the barrel polishing apparatus 1. The first abrasive 31 that is an abrasive for the first workpiece 21 suitable for polishing the first workpiece 21 is directly charged. The first workpiece 21 is made of resin or metal. The abrasive suitable for polishing the first workpiece 21 is an abrasive configured with a material and a size capable of polishing the first workpiece 21 efficiently and reliably. As the abrasive, various types of abrasive such as a metal abrasive, a resin abrasive, and a ceramic abrasive can be used. Moreover, the abrasive | polishing agent can use the abrasive | polishing agent of various shapes according to a use. In some cases, the lubricating liquid is also put into the polishing tank 11 together.

  In the abrasive | polishing agent used in barrel grinding | polishing, in order to respond | correspond to the barrel grinding | polishing of a multiple types of workpiece, the grinding | polishing agent comprised by the various material and magnitude | size exists. However, if polishing is not performed using an abrasive suitable for each workpiece, the polishing efficiency is poor and the processing time is increased, the workpiece is not reliably polished, and the workpiece is polished more than necessary. And other problems occur. Therefore, it is important to use an abrasive suitable for each workpiece in order to perform high-quality barrel polishing.

  The polishing tank 11 is made of a resin material or a metal material. As the polishing tank 11, it is preferable to use a U-shaped longitudinal section because the flow of the first workpiece 21 and the first abrasive 31 in the polishing tank 11 becomes smooth.

  When a plurality of workpieces having different sizes are simultaneously polished in the barrel polishing apparatus 1, a barrel polishing container jig is put into the polishing tank 11. The barrel polishing container jig is made of resin or metal and is configured to be divided into a plurality of divided parts. FIG. 2 is a schematic diagram showing a first barrel polishing container jig 41 which is a first example of a barrel polishing container jig according to an embodiment of the present invention. In FIG. 2, the figure which looked at the container barrel 41 for 1st barrel polishing from diagonally upward is shown. FIG. 3 is a cross-sectional view of the first barrel polishing container jig 41 according to the embodiment of the present invention. FIG. 4 is a cross-sectional view showing a state where the first barrel polishing container jig 41 according to the embodiment of the present invention is disassembled. Hereinafter, the first barrel polishing container jig 41 is referred to as a first container jig 41.

  As shown in FIG. 2, the first container jig 41 according to the embodiment has a cylindrical outer shape in which an end is a hemispherical shape. Further, as shown in FIGS. 3 and 4, the first container jig 41 is a hollow container having a uniform thickness on the outer surface, an inner shape along the outer shape, and a hollow inside. ing. In the first container jig 41, the second workpiece 22 and the second abrasive 32 are enclosed. In some cases, the lubricating liquid is also enclosed in the first container jig 41.

  Here, the second workpiece 22 is a workpiece that is relatively smaller in size than the first workpiece 21 that is directly put into the polishing tank 11, and is different from the first workpiece 21. It is composed of The second workpiece 22 is made of resin or metal. The second abrasive 32 is an abrasive for the second workpiece 22 that is suitable for polishing the second workpiece 22, and is an abrasive different from the first abrasive 31. The abrasive suitable for polishing the second workpiece 22 is an abrasive configured with a material and a size capable of polishing the second workpiece 22 efficiently and reliably. That is, since the second workpiece 22 is smaller than the first workpiece 21 and has different constituent materials, the first workpiece 21 and the second workpiece 22 have different abrasives.

  Even when the second workpiece 22 is relatively smaller in size than the first workpiece 21 and is made of the same material as the first workpiece 21, the second workpiece 22 is polished. A polishing agent suitable for is different from the first polishing agent 31. Further, even when at least one of the size, shape, and material of the second workpiece 22 is different from that of the first workpiece 21, the abrasive suitable for polishing the second workpiece 22 is the first abrasive. 31 is different.

  As for the 1st container jig | tool 41, the both ends of the longitudinal direction in an inner surface and an inner surface are comprised using the curved surface. That is, as for the 1st container jig | tool 41, the inner surface has a cylindrical shape, and the both ends of the longitudinal direction in the inner surface are hemispherical. By configuring the inner surface of the first container jig 41 by using a curved surface, the second workpiece 22 and the second abrasive 32 can easily flow inside the first container jig 41 during the polishing process, thereby improving efficiency. The second workpiece 22 can be polished efficiently and reliably.

  Moreover, the 1st container jig | tool 41 is comprised using the curved surface in the both ends of the longitudinal direction in an outer surface. That is, as for the 1st container jig | tool 41, the both ends side of the longitudinal direction in an outer surface is made hemispherical shape. By configuring the outer surface of the first container jig 41 using a curved surface, the first workpiece 21 and the first abrasive 31 flow around the first container jig 41 in the polishing tank 11 during the polishing process. This makes it possible to polish the first workpiece 21 efficiently. Accordingly, the outer shape of the barrel polishing container jig according to the present embodiment is a structure using a curved surface, such as a spherical shape, an ellipsoidal shape, a cylindrical shape, and a cylindrical shape whose end is a hemispherical shape. Is preferred.

  Further, the first container jig 41 is made of a material having wear resistance with respect to the first abrasive 31. Thereby, even when repeatedly used in the barrel polishing apparatus 1, the life of the first container jig 41 is extended.

  As shown in FIG. 4, the first container jig 41 can be divided into a first divided portion 42 and a second divided portion 43 in the central region in the longitudinal direction. The first divided portion 42 has a ring-shaped attachment portion 42b having a stepped portion 42c having the same width in the circumferential direction around the axis of the first container jig 41 on the inner surface adjacent to the opening end 42a. The second divided portion 43 has a ring-shaped attachment portion 43b provided with a step portion 43c having the same width in the circumferential direction around the axis of the first container jig 41 on the outer surface adjacent to the opening end 43a.

The The order in which the first step and the second step are performed may be reversed.

  Subsequently, in step S30, which is the third step, the barrel polishing apparatus 1 is activated. That is, when the motor 18 is driven, the rotating shaft 15 rotates. At this time, since the unbalance weight 17 is fixed to a part of the rotating shaft 15, the rotating shaft 15 rotates while swinging in the horizontal direction. As the rotary shaft 15 swings and tilts in the horizontal direction, the polishing tank 11 also tilts. By supporting the slanting polishing tank 11 with a spring 13 as an elastic member, the polishing tank 11 rotates while drawing a substantially circular trajectory in the horizontal direction while vibrating in response to the rotation of the unbalance weight 17. .

  Further, as the first workpiece 21 and the first abrasive 31 flow, the first container jig 41 also rotates and flows in the polishing tank 11 in the same manner as the first workpiece 21. Then, as the first container jig 41 rotates and flows in the polishing tank 11, the second workpiece 22 and the second abrasive 32 in the first container jig 41 move relative to each other. The workpiece 22 is polished by the second abrasive 32. That is, when the first container jig 41 vibrates or rotates in conjunction with the flow of the first abrasive 31 in the polishing tank 11, the second abrasive 32 and the workpiece in the first container jig 41 are moved. And relative movement.

  By performing the above processing, in the barrel polishing apparatus 1, the first workpiece 21 and the second workpiece 22 having different sizes can be individually polished in different processing spaces. This makes it possible to polish the first workpiece 21 and the second workpiece 22 with different abrasives in the same batch with the abrasive suitable for each workpiece. Further, the first workpiece 21 and the second workpiece 22 do not collide during the polishing process, and a collision dent resulting from the collision between the first workpiece 21 and the second workpiece 22 and The occurrence of scratches can be prevented, and the yield in polishing of the first workpiece 21 and the second workpiece 22 is improved.

  After the polishing process, in step S40, which is the fourth step, the first container jig 41 is taken out from the polishing tank 11, and the first container jig 41 is disassembled. Thereby, the second workpiece 22 can be easily sorted, and the time required for sorting the second workpiece 22 can be reduced. That is, since the removal of the second workpiece 22 after the polishing process is completed is the selection of the second workpiece 22 from the first container jig 41, the second workpiece 22 which is a small component. The sorting time can be shortened. Further, the risk of losing the second workpiece 22 that is a small component is reduced.

  In addition, a plurality of workpieces that are smaller than the first workpiece 21 and have different sizes are sealed in the plurality of first container jigs 41 for each size. May be. In this case, an abrasive suitable for the workpiece to be sealed in the first container jig 41 is sealed in accordance with the first container jig 41. And each 1st container jig | tool 41 is thrown into the grinding | polishing tank 11, and a grinding | polishing process is performed like the above. This makes it possible to polish three or more types of workpieces with different suitable abrasives in the same batch with an abrasive suitable for each workpiece.

  In the above description, the second workpiece 22 is smaller than the first workpiece 21 and is made of a material different from that of the first workpiece 21, but the second workpiece 22 is shown. Even when at least one of the size, shape, and material is different from that of the first workpiece 21, the abrasive suitable for polishing the second workpiece 22 is different from that of the first abrasive 31. Accordingly, when at least one of the size, shape, and material of the second workpiece 22 is different from that of the first workpiece 21, the second workpiece 22 and the second abrasive 32 are used in the same manner as described above. By enclosing in one container jig 41 and performing a polishing process, a plurality of different kinds of workpieces having different sizes, shapes and materials in the same batch are suitable for each workpiece. Polishing with an abrasive becomes possible.
