Adjustable positioning milling fixture with uniform clamping force

Abstract

The invention relates to the technical field of motor machining, and discloses an adjustable positioning milling fixture with uniform clamping force. The milling fixture comprises a mounting table, the top of the mounting table is fixedly connected with a connecting block, four evenly distributed sliding holes are formed in the side wall of the connecting block, the four sliding holes communicate,sliding rods are in sliding connection to the inner walls of the four sliding holes, the ends, located in the connecting block, of the four sliding rods are fixedly connected with limiting blocks, limiting grooves are formed in the inner walls of the four sliding holes, the four limiting blocks are in sliding connection with the inner walls of the four limiting grooves, the ends, outside the connecting block, of the four sliding rods are fixedly connected with a first arc clamping plate, and a transmission box is fixedly connected to the bottom of the mounting table. According to the adjustable positioning milling fixture with uniform clamping force, a motor shell is sleeved with the position between a first clamping plate and a second clamping plate, the side wall stress area of the motor shell is increased, clamping force is transmitted by two opposite directions, and when the motor shell is clamped, the shell is not prone to deforming.

Description

technical field [0001] The invention relates to the technical field of motor processing, in particular to a milling fixture with uniform clamping force and adjustable positioning. Background technique [0002] In the field of mechanical processing, the outer circle is often used as the positioning and installation reference for milling grooves of thin-walled motor casings, and most of them are manually clamped. However, this operation method leads to low production efficiency and is time-consuming and laborious. [0003] After searching, the Chinese patent authorization number is CN201310271640.1, which discloses an adjustable positioning milling fixture, including the fixture body. The adjustable positioning milling fixture in the above-mentioned patent has the following disadvantages: the guide rail is installed on the clamp body, there is a threaded track at the bottom of the slider, and the threaded guide rail on the upper part of the slider and the positioning block mes...
