Description

Technical Field

[0001] This utility model belongs to the field of mechanical parts manufacturing technology, specifically relating to an automated machining fixture for multiple workpieces. Background Technology

[0002] In existing workpiece processing, the geometric center of the screw hole on the workpiece base may not be at the center of the workpiece, which means the workpiece cannot be clamped in the center of the tooling plate. This makes automated processing impossible and can only be done manually. Generally, single-piece processing is used. Each time a workpiece is processed, the machine is stopped once to calibrate the workpiece, which seriously affects processing efficiency and increases processing costs. Summary of the Invention

[0003] To address the technical problem of time-consuming and labor-intensive single-piece processing in the prior art, this application proposes an automated multi-workpiece processing fixture, which solves the aforementioned technical problem.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] This utility model provides a multi-workpiece automated processing fixture, comprising: a pallet with screw holes on its receiving surface; a workpiece plate placed on the receiving surface of the pallet, with connecting holes at each of the four corners of the workpiece plate, a connecting step formed on the side of the connecting hole facing away from the pallet, a connecting bolt fitted into the connecting hole, the threaded portion of the connecting bolt penetrating the workpiece plate and screwed into the screw hole of the pallet, the nut portion of the connecting bolt pressing against the connecting step to connect and fix the workpiece plate to the pallet; a positioning hole in the center of the workpiece plate, a positioning step formed on the side of the positioning hole facing the pallet, a positioning bolt fitted into the positioning hole; and a workpiece blank, the workpiece blank comprising parts attached to the pallet plate. The workpiece plate has a bottom plane with a threaded hole. The screw portion of the positioning bolt passes through the workpiece plate and is screwed into the threaded hole of the workpiece blank. The nut portion of the positioning bolt is pressed onto the positioning step to position the workpiece blank on the workpiece plate. After one processing, the workpiece blank is formed into a workpiece semi-finished product. The workpiece semi-finished product includes multiple workpiece prototypes and a base plate connecting the multiple workpiece prototypes together. The top plane of the workpiece prototype facing away from the base plate has a threaded hole. The workpiece semi-finished product is removed from the workpiece plate and flipped so that the top plane of the workpiece prototype is attached to the workpiece plate. The positioning bolt is used again to position the workpiece semi-finished product on the workpiece plate for secondary processing and to complete the production of the workpiece.

[0006] Furthermore, the connecting hole is an arc-shaped slot.

[0007] Furthermore, the nut portion of the connecting bolt screwed into the connecting hole does not protrude from the workpiece plate.

[0008] Furthermore, the positioning hole is an elongated slot; or, some of the positioning holes are elongated slots and some of the positioning holes are circular holes.

[0009] Furthermore, the nut portion of the positioning bolt screwed into the positioning hole does not protrude from the workpiece plate.

[0010] Furthermore, an elongated groove is formed on the side of the workpiece plate to create a gripping portion.

[0011] Furthermore, each of the individual workpiece prototypes and the workpiece plate has at least two positioning points.

[0012] Furthermore, the thickness of the base plate is not less than 20mm.

[0013] Based on the above technical solution, the technical effects that this utility model can achieve are as follows:

[0014] This utility model's multi-workpiece automated machining fixture can process multiple workpieces at once, with each workpiece undergoing secondary processing. After the first processing, the multiple workpieces are not separated, and each individual workpiece is independently positioned on the workpiece plate, enabling the secondary processing to be completed. This utility model's multi-workpiece automated machining fixture can make the geometric centers of multiple workpieces coincide with the center of the fixture plate, thereby achieving automated processing, saving manpower and processing time, and improving processing efficiency.
