Machining fixture

Abstract

The invention discloses a machining fixture. The machining fixture comprises a bottom plate, wherein the bottom plate is rectangular; stepped fixing holes are formed in four corners of the bottom plate; a plurality of positioning pin holes are formed in the bottom plate; one end of a positioning pin is arranged in two of the positioning pin holes; a fixing disc is arranged at the other end of the positioning pin in a sleeving manner; totally two side plates are fixedly arranged on the bottom plate through bolts; center holes are formed in the side plates; center mechanisms are arranged in the center holes; and an adjustable lifting jack, an infrared counter and a locking mechanism are arranged on the bottom plate. The positioning pin, the adjustable lifting jack, the pressing plate, two centers and the locking mechanism are arranged on the bottom plate of the fixture, some functions can be selected according to needs when the fixture is used, and unnecessary functions are removed. The problem that the fixture needs to be frequently replaced during workpiece machining is solved, the replacement frequency is reduced, and the machining efficiency is improved. The machining fixture disclosed by the invention has the characteristics of high universality and convenience and rapidness in use.

Description

technical field [0001] The invention relates to the technical field of machining tools, in particular to a machining fixture. Background technique [0002] As a necessary equipment in the machining process, the fixture plays an extremely important role in its processing. The fixture plays the role of positioning (restricting the degree of freedom of the workpiece) and clamping the workpiece, especially the shapes of rough-machined parts are different. , Different fixtures need to be designed, so there are relatively many fixtures needed, and the management of fixtures is relatively cumbersome. [0003] The existing tooling fixtures are cumbersome to use, and the versatility is not strong. Generally, one fixture is required for a single part in one process, and different fixtures need to be replaced for different processed products. It is also quite troublesome to replace the fixture. The working table of the machine tool needs to be proofread, marked, leveled, etc., so it i...

[0003] The existing tooling fixtures are cumbersome to use, and the versatility is not strong. Generally, one fixture is required for a single part in one process, and different fixtures need to be replaced for different processed products. It is also quite troublesome to replace the fixture. The working table of the machine tool needs to be proofread, marked, leveled, etc., so it is extremely inconvenient to use and seriously affects the efficiency of machining
