Preferably, a first workpiece supporting block in direct contact with a workpiece to be processed is arranged on one side, facing the pushing mechanism, of the fixing clamping block, the first workpiece supporting block is detachably connected with the fixing clamping block, a second workpiece supporting block in direct contact with the workpiece to be processed is arranged on one side, facing the fixing clamping block, of the pressing block, and the second workpiece supporting block is detachably connected with the pressing block.

Preferably, the driving part comprises an air cylinder and a rigid connecting rod, one end of the rigid connecting rod is connected with the acting force output end of the air cylinder, the other end of the rigid connecting rod is connected with the pressing block, and the air cylinder transmits acting force to the pressing block through the rigid connecting rod.

Preferably, two supporting cushion blocks which are arranged oppositely are arranged on one side, back to the plurality of groups of mutually oppositely arranged fixed clamping blocks and pushing mechanisms, of the workbench.

Compare with current work piece adds clamping apparatus structure, the utility model discloses an among the work piece adds clamping apparatus, fixed clamp splice and match the guide block that is provided with the spacing through-hole between the pushing mechanism who uses with fixed clamp splice, when pushing mechanism's briquetting and fixed clamp splice match the centre gripping work piece, the briquetting need be through spacing through-hole. When the pressing block is close to or far away from the fixed clamping block, the inner wall of the limiting through hole prevents the pressing block from moving radially, so that the influence of the vibration of the driving part on the pressing block is reduced.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the following detailed description of the embodiments of the present invention will be described with reference to the accompanying drawings. Examples of these preferred embodiments are illustrated in the accompanying drawings. The embodiments of the invention shown in the drawings and described in accordance with the same are merely exemplary and the invention is not limited to these embodiments.

To address the problems of the prior art discussed in the background section, the present embodiment provides a workpiece machining jig. As shown in fig. 1 (fig. 1 is a side view of the workpiece machining jig of the present embodiment, and only one of the following sets of fixed clamping blocks and pushing mechanisms disposed opposite to each other is shown), the workpiece machining jig of the present embodiment includes a table 1 and a set of fixed clamping blocks 2 and pushing mechanisms disposed on the table 1 and disposed opposite to each other. And a guide block 3 with a limiting through hole A is arranged between each group of the fixed clamping blocks 2 and the pushing mechanism.

The pushing mechanism comprises a pressing block 41 and a driving part 42 capable of providing acting force for the pressing block 41, and at least part of the pressing block 41 is embedded in the limiting through hole A. The pressing block 41 is close to or far away from the fixed clamping block 2 through the limiting through hole A under the action of the driving part 42.

When the pressing block 41 is close to or far from the fixed clamping block 2 under the action of the driving part 42, at least part of the pressing block 41 is always embedded in the limiting through hole a, and the inner wall of the limiting through hole a prevents the pressing block 41 from moving radially. It should be noted that, in this document, a linear direction in which a moving track of the pressing block 41 approaching or departing from the fixed clamping block 2 is defined as an axial direction of the pressing block 41, and a direction perpendicular to the axial direction of the pressing block 41 is defined as a radial direction of the pressing block 41.

Compared with the existing workpiece machining fixture structure, in the workpiece machining fixture of the embodiment, the guide block 3 with the limiting through hole a is arranged between the fixed clamping block 2 and the pushing mechanism matched with the fixed clamping block 2, and when the pressing block 41 of the pushing mechanism is matched with the fixed clamping block 2 to clamp a workpiece, the pressing block 41 needs to pass through the limiting through hole a. When the pressing block 41 is close to or far from the fixed clamping block 2, the inner wall of the limiting through hole A prevents the pressing block 41 from moving radially, so that the influence of the vibration of the driving part 42 on the pressing block 41 is reduced.

Preferably, a first workpiece supporting block 21 in direct contact with a workpiece to be processed is arranged on one side of the fixed clamping block 2 facing the pushing mechanism, and the first workpiece supporting block 21 is detachably connected with the fixed clamping block 2. A second workpiece supporting block 41a which is in direct contact with a workpiece to be processed is arranged on one side of the pressing block 41 facing the fixed clamping block 2, and the second workpiece supporting block 41a is detachably connected with the pressing block 41.

Specifically, the driving portion 42 includes an air cylinder 42a and a rigid connecting rod 42b, one end of the rigid connecting rod 42b is connected to the force output end of the air cylinder 42a, and the other end of the rigid connecting rod 42b is connected to the pressing block 41. The cylinder 42a transmits a force to the pressure piece 41 through the rigid connecting rod 42 b.

Optionally, two supporting cushion blocks 5 arranged opposite to each other are arranged on one side of the workbench 1 facing away from the plurality of groups of fixed clamping blocks 2 arranged opposite to each other and the pushing mechanism. The shape of the limiting through hole A is the same as the radial section shape of the pressing block 41.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
