Positioning device with limiting function

Abstract

The invention discloses a positioning device with a limiting function. The positioning device comprises a bottom plate, a clamping plate and a screw; the front end of the bottom plate is provided with a V-shaped block, and the rear end of the bottom plate is provided with a threaded hole; the rear end of the clamping plate is embedded into a sliding chute formed on the bottom plate; one end of the screw penetrates through the bottom plate and is fixedly connected with the threaded hole at the rear end of the clamping plate, and the other end of the screw is positioned on the bottom plate through a nut; the defects that a clamp has a single purpose, because a clamping plate can only clamp a workpiece with one size in the prior art can be overcome; and the improved positioning device is provided, workpieces with different sizes can be processed, and the manufacturing cost of the clamp is saved.

Description

technical field [0001] The invention belongs to a machining positioning fixture, in particular to a position-limiting positioning device. Background technique [0002] During mechanical processing, the shape and size of the processed parts are different. Usually, the positioning device is made separately for the processed parts. However, it will be wasteful to use this method when facing the processed parts with similar appearance and similar size. Material, there is no need to do this. Later, a fixture was improved, and a spring was installed inside. Although the elastic force of the spring was used to increase the size of the workpiece clamped by the positioning device, a new problem appeared. Finally, the fixture is reset, and the next time the same type of workpiece is loaded, it needs to be clamped again, resulting in a waste of processing time, and it cannot be clamped in large quantities. Contents of the invention [0003] The technical problem to be solved by the ...

[0002] During mechanical processing, the shape and size of the processed parts are different. Usually, the positioning device is made separately for the processed parts. However, it will be wasteful to use this method when facing the processed parts with similar appearance and similar size. Material, there is no need to do this. Later, a fixture was improved and a spring was installed inside. Although the elastic force of the spring was solved and the size of the workpiece clamped by the positioning device was increased, a new problem appeared. After that, the fixture is reset, and the next time it is loaded into the same kind of workpiece, it needs to be clamped again, resulting in a waste of processing time, and it is impossible to perform large-scale clamping
