Description

A positioning fixture with convenient clamping

Technical Field

The utility model relates to the technical field of working clamps, in particular to a positioning clamp which is convenient for clamping.

Background Art

A positioning fixture usually consists of a fixture seat, a fixture block, a fixture claw, etc. The positioning and fixation of the workpiece are achieved by arranging the position, shape and clamping force of the fixture block and the fixture claw. The fixture seat is the supporting part of the fixture and is usually installed on the workbench of the machine tool or the moving device of the workbench. The design and manufacture of the positioning fixture need to consider factors such as the shape, size, and processing technology of the workpiece to ensure that the fixture can accurately position and fix the workpiece, while ensuring the rigidity and stability of the fixture during the processing. The design of the fixture should take into account the convenience, safety and efficiency of operation to improve production efficiency and processing quality. The positioning fixture plays a vital role in machine tool processing. It can improve production efficiency, reduce the impact of human operating errors, and improve processing accuracy and consistency. At the same time, it can also protect the surface of the workpiece and avoid damage due to improper clamping. Therefore, the reasonable design and use of positioning fixtures are of great significance to ensuring processing quality and production efficiency.

The patent document with application number CN202222373639.7 discloses a machine tool fixture that is easy to position, which includes: a fixed plate, the surface of which is slidably connected to a workbench; however, the currently existing positioning fixtures have some limitations when clamping objects, mainly manifested in that there is a back plate inside the fixture, and the distance between the back plate and the clamping plate is relatively close. This design results in the fixture being able to clamp only the edge area of the object. For objects that are long or large in size, the clamping effect is poor or even impossible to clamp. This problem not only affects the function of the fixture, but also has a serious impact on the progress of subsequent processing operations.
