Inner dimension of the product to expand the fixing device

Abstract

The invention discloses a product inner size expanding fixing device. The product inner size expanding fixing device comprises a propelling air cylinder, a material groove, a first oblique block, a second oblique block, a first sliding block, a second sliding block, a first cam sliding block and a second cam sliding block. The propelling air cylinder is connected with the first oblique block, thefirst cam sliding block is located on the upper oblique face of the first oblique block, the upper face of the first cam sliding block corresponds to the lower oblique face of the second oblique sliding block, the second cam sliding block is located on the second oblique block, the first sliding block is connected with the first cam sliding block, the side face of the first sliding block is of anoblique face structure, the side face of the first sliding block is connected with one side of the second cam sliding block, the material groove is located above the second cam sliding block, and thesecond cam sliding block is connected with the second sliding block. The product inner size expanding fixing device has the effects that when a product is internally expanded and clamped, the labor issaved, and the efficiency is improved.

Description

technical field [0001] The invention relates to the field of cam transmission and fixing, in particular to a device for expanding and fixing inner dimensions of products. Background technique [0002] In the prior art where the clamping of the product is internal expansion and clamping, the product is generally placed and tightened by hand to expand and clamp the product. It takes a long time to manually tighten the screw, and it needs to be fixed with an air cylinder at the fixed point and then rotated. Tight, the average manual tightening per minute is 40pcs, the labor is easy to be tired, the work efficiency is low, and the product processing cycle time is long. Contents of the invention [0003] According to one aspect of the present invention, there is provided a product internal size expansion and fixing device, including a push cylinder, a trough, a first inclined block, a second inclined block, a first slider, a second slider, a first cam slider and The second cam...
