Abstract

The invention discloses an expander device for secondary positioning of a three-pin shaft fork. The expander device sequentially comprises an expander body and an outer sleeve from left to right, a mandrel is slidably arranged inside the axial middles of the expander body and the outer sleeve in a penetrating manner, the expander body is connected with a main shaft of driving equipment, the mandrel is connected to an air cylinder of the driving equipment, the mandrel is sequentially sleeved with a compression spring, a first inclined block and a second inclined block from left to right, inclined surfaces which are gradually reduced from left to right are arranged on the top of the first inclined block and the top of the second inclined block correspondingly, tensioning blocks are vertically inserted on the outer sleeve, the shapes of the bottoms of the tensioning blocks are matched with the inclined surfaces and are in sliding abutting contact with the inclined surfaces, an inner cavity of the three-pin shaft fork blank part sleeves the right end of the outer sleeve from right to left, and a center hole of the right end face of the three-pin shaft fork blank part is horizontally abutted with a center. According to the expander device for the secondary positioning of the three-pin shaft fork, the structural design is reasonable, the situation that the manual feeding error exists, the feeding is not in place and a positioning pin cannot be abutted can be eliminated through the axial secondary positioning and by matching the controlling action of a numerical control program ofa machine tool, and the machining precision of a part is greatly improved.

Description

technical field [0001] The invention relates to a tire-increasing device for auto parts, in particular to a tire-increasing device for secondary positioning of a three-pin shaft fork. Background technique [0002] Currently on the market, the three-pin shaft fork in the auto parts usually adopts a tire expansion device to tighten the inner cavity of the part during processing and production, and utilizes the positioning pin at the front end of the tire to tighten the bottom of the inner cavity of the part for positioning. However, due to manual loading during clamping and positioning, the operator often fails to feed the material in the axial direction when the tire is clamped manually, and cannot be close to the positioning pin, and often affects the processing accuracy of the part due to insufficient feeding. Condition. [0003] In summary, there is a need for a three-pin shaft fork tire expansion device with reasonable structural design and accurate axial positioning. ...
