Description

Technical Field

[0001] This utility model relates to the field of hardware processing technology, and in particular to a lathe fixture for irregularly shaped parts. Background Technology

[0002] Currently, metal processing is the process of making various metal parts from metal materials through physical processing methods such as forging, rolling, and cutting. Its processing technology includes stamping, CNC turning, welding, and surface treatment.

[0003] CNC turning mainly involves clamping the workpiece onto the spindle using a three-jaw chuck, and then feeding the cutting tool axially through the spindle's rotation to complete machining operations such as external diameters, internal holes, and threads.

[0004] However, in practical applications, most cylindrical workpieces are easy to install onto a three-jaw chuck for clamping. But for the threaded hole processing requirements of some irregular parts such as flow meter bodies, conventional three-jaw chucks cannot perform clamping and processing operations on irregular workpieces, so improvements are needed. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a lathe fixture for irregular parts, which can facilitate the turning of irregular parts.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A lathe fixture for irregularly shaped parts includes a coaxial fixed seat, a mounting seat, and a quick-change locking clamp. The coaxial fixed seat is cylindrical and is fixedly connected to the mounting seat. The workpiece is mounted on the mounting seat, and the quick-change locking clamp is mounted on the mounting seat for locking and fixing the workpiece. The axis of the coaxial fixed seat overlaps with the turning axis of the workpiece.

[0008] By adopting the above technical solution, using the coaxial fixed seat and mounting seat as a carrier, and utilizing the quick-locking and fixing effect of the quick-change locking fixture, the axis of the coaxial fixed seat is set to be coaxial with the turning axis of the workpiece, so as to meet the clamping and turning operation of irregular workpieces.

[0009] In one possible implementation, the mounting base includes a connecting part, a platform part, and a mounting part. The connecting part is coaxially connected to the coaxial fixing base, the platform part is connected to the connecting part, the workpiece is mounted on the platform part, the mounting part is disposed on the platform part and located on one side of the workpiece, the quick-change locking clamp is mounted on the mounting part, and the clamping part of the quick-change locking clamp can be rotated to clamp the upper end of the workpiece.

[0010] By adopting the above technical solution, the connection part and the platform part are designed to facilitate the installation of the workpiece and to achieve coaxial connection with the coaxial fixed seat. The installation part is designed to facilitate the installation of the quick-change locking fixture and to facilitate the clamping operation of the workpiece.

[0011] In one possible implementation, at least two quick-change locking fixtures are arranged along the workpiece turning axis, and each quick-change locking fixture is installed to the mounting part.

[0012] By adopting the above technical solution, the number of quick-change locking fixtures is increased, thereby improving the stability of locking and fixing the workpiece.

[0013] In one possible implementation, the platform section is provided with positioning pins to fit the slots of the workpiece body.

[0014] By adopting the above technical solution, the positioning pin is set to facilitate workpiece positioning and improve machining accuracy.

[0015] In one possible implementation, two locating pins are provided, both of which are adapted to fit into the slots of the workpiece body.

[0016] By adopting the above technical solution and setting two positioning pins, the positioning accuracy is improved, and the workpiece can be easily switched in direction for turning after switching positioning.

[0017] In one possible implementation, the platform section is provided with mounting holes, and both positioning pins are interference-fitted into the mounting holes.

[0018] By adopting the above technical solution, the mounting hole design facilitates the installation of the locating pin.

[0019] In one possible implementation, the platform section is provided with fixing holes for mounting the installation section, and the fixing holes are arranged on both sides of the workpiece.

[0020] By adopting the above technical solution, and by providing fixing holes on both sides of the workpiece on the platform, the number of quick-change locking fixtures can be easily and adaptably selected.

[0021] Compared with existing technologies, the advantages of this utility model are:

[0022] 1. By using a coaxial fixed base and a mounting base as a carrier, and taking advantage of the quick-locking and fixing effect of the quick-change locking fixture, the axis of the coaxial fixed base is set to be coaxial with the turning axis of the workpiece, so as to realize the clamping and turning operation of irregular workpieces.

[0023] 2. By using two locating pins and a quick-change locking fixture, it is possible to quickly switch between turning operations at both ends of the workpiece, thereby improving processing efficiency and enhancing processing accuracy through positioning. Attached Figure Description
