Description

  The present invention relates to a workpiece support device that stably supports a workpiece in a positioned state by a support member that can be adjusted in position according to the size and shape of the workpiece when performing a required process on the workpiece.

  For example, in a workpiece such as a molded resin product after molding, burrs are integrated with the outer peripheral edge of the product. In order to obtain a product, it is necessary to cut and remove the burrs. Moreover, in order to commercialize a workpiece, it is necessary to perform various types of processing such as drilling and trimming on the workpiece. When performing such processing, it is necessary to set it on a workpiece support jig that supports and holds the workpiece in the positioned state, but when the size and shape of the workpiece to be processed are different Requires a workpiece support jig in which a support member is arranged corresponding to the workpiece.

  For this reason, it is necessary to prepare a plurality of workpiece support jigs that differ depending on the type of workpiece, which increases the equipment cost and requires a large stock space.

  In order to solve the above-described problem, for example, a workpiece support device shown in Patent Document 1 has been proposed. The work support device reciprocally accommodates a support piston that moves between a forward limit position and a backward limit position where the support rod contacts the work, and supports the forward pressure chamber on the rear end face side of the support piston. A reciprocating motion in the axial direction is possible in a support base formed with a plurality of cylinder chambers divided into a pressure chamber for retraction on the front end face side of the piston and a valve chamber formed in the support base in communication with the pressure chamber for advancement And a pressure-receiving surface that is provided on the opposite side of the facing surface and that has a larger diameter than the facing surface, and a pressure-receiving surface and a pressure-receiving surface. A switching valve formed with a through-hole to be communicated with, and is accommodated in a receiving hole formed in the support base so as to communicate with the valve chamber so as to be reciprocatingly opposed to the pressure-receiving surface of the switching valve, and is supported via the switching valve. Set up the piston between the forward limit position and the reverse limit position A switching piston that is driven to the position, a switching passage that is formed in the support base and supplies fluid pressure to the switching piston toward the setup position, and a support piston that is formed in the support base via the switching valve. When the support piston is moved to the retreat limit position, the communication with the forward pressure chamber is communicated by the switching valve. A plurality of supports having a forward flow path to be blocked and a backward flow path formed in the support base and communicating with the pressure chamber for retraction, and selectively moved to the forward limit position according to the support location of the workpiece The workpiece is configured to be supported by the rod.

  However, in the above-described work support device, the size of the work to be supported is limited to the size of the support base, and it is not possible to support a work larger than the support base, and the support pins are disposed at the support position of the work. When the position is shifted, there is a problem that the workpiece cannot be stably supported in a positioned state.

Further, when processing a workpiece, it is necessary to change the support posture of the workpiece such as a forward inclined state, a backward inclined state, a horizontal state, etc. according to the size and shape of the workpiece. In this case, since each support pin protrudes and is supported to a certain height, the workpiece cannot be supported in the forward inclined state and the backward inclined state, and there is a problem that the processing cannot be performed efficiently.

  Furthermore, it is necessary to provide a switching valve according to each support pin, and to control each switching valve so as to move the selected support pin according to the support location, which complicates the control mechanism of the switching valve and increases the device. There is a problem of cost.

  Furthermore, in order to perform processing such as drilling or cutting using a drilling tool such as a drill at a predetermined predetermined processing location of the workpiece supported by the workpiece support device described above. Performs a desired process by pressing a processing member such as a drilling tool or a rotary blade against the processing part of the workpiece. However, although the above-described workpiece support device can support a portion away from the machining location, it is not configured to support the periphery of the machining location. For this reason, the workpiece may be bent or displaced due to the pressing of the processing member, and the processing accuracy may be deteriorated.

In addition, the work cannot be supported in an arbitrary support posture, and the processing work cannot be performed efficiently. Furthermore, it is necessary to provide a switching valve according to each support pin, and it is necessary to control each switching valve so as to move the selected support pin according to the support location, which complicates the control mechanism of the switching valve and reduces the apparatus cost. The point is to increase. Furthermore, when machining the workpiece, the workpiece is supported at a location away from the machining location, so that the workpiece is bent or displaced due to pressing by the processing member, etc., and the machining accuracy deteriorates. is there.
