Precise fixture with buffer function

Abstract

The invention discloses a precise fixture with a buffer function. The precise fixture comprises a support bottom base; a support base is arranged on the outer wall of one side of the top of the support bottom base; a forward / reverse rotating motor is arranged on the outer wall of the top of the support base; a driving belt wheel is arranged on an output shaft of the forward / reverse rotating motor;a first fixed block and a second fixed block are arranged at two ends of the outer wall of one side of the top of the support bottom base; through holes are formed in the middle position of the firstfixed block and the middle position of the second fixed block; rotating shafts are arranged on the inner walls of the through holes; and first thread lead screws and second thread lead screws are arranged on the outer walls of one sides of the rotating shafts. A spring, a buffer cylinder, a buffer rod and a connecting rod are used for efficient buffering in the fixture clamping process, so that the device can clamp flat, circular, cylindrical and square parts, the clamping of the parts with different shapes is realized, and the clamping by the fixture is more precise.

Description

technical field [0001] The invention relates to the technical field of precision fixtures, in particular to a precision fixture with a buffer function. Background technique [0002] In the production process of mechanical parts, it is necessary to fix the parts by fixtures so that the parts can be processed under stable adjustment. The precision performance of the fixtures affects the clamping effect of the fixtures and the stability of the parts. [0003] At present, the existing precision fixtures have a complex structure. When fixing parts, usually only one part can be fixed. After each processing, the operation of the machine needs to be stopped, and then the parts are replaced to continue processing. It takes a lot of time to replace the parts. , reduce the work efficiency of workers, and in the process of parts clamping, it is necessary to have a good cushioning effect on the fixture, so as to ensure that the clamping process can stably and reliably meet the requiremen...
