Sleeve grinding fixture

Abstract

The invention relates to the technical field of work fixtures, and provides a sleeve grinding fixture. The sleeve grinding fixture comprises a cylindrical mandrel and two deformation mechanisms which are the same and are oppositely arranged on the mandrel. Each deformation mechanism comprises a gas bag, a nut, a plurality of supporting rods and a plurality of fixing plates. The nuts are connected with the mandrel in a threaded mode. The supporting rods are all hinged to the nuts and can rotate relative to the nuts. One ends of the fixing plates are hinged to the mandrel, and the other ends of the fixing plates are hinged to the supporting rods. The multiple fixing plates can form a cone around the mandrel and further be used for fixing a sleeve. The gas bags comprise gas inlets used for leading in gas and gas outlets used for blowing the gas to the outer circle of the sleeve, and the gas bags are arranged in the cone. According to the technical scheme, the sleeve grinding fixture provided by the invention is easy to operate, clamping and dismounting efficiency can be effectively improved, the range of application is wide, and grinding chips can further be cleared up in time.

Description

technical field [0001] The invention relates to the technical field of fixtures, in particular to a sleeve grinding fixture. Background technique [0002] The socket is a tool commonly used in automobile maintenance, and is often used to tighten or remove screws. Its structure usually includes an inner hole and an outer circle, the inner hole is mainly used for supporting and guiding, and the outer circle is generally used to contact other parts to play a supporting role. When processing the sleeve, it is usually necessary to clamp the sleeve to grind its outer circle and inner hole, and it is necessary to ensure the coaxiality of the outer circle and inner hole. However, due to the difficulty of clamping, it is often difficult to achieve shape and position tolerances (i.e. shape tolerance and position tolerance) requirements. [0003] The traditional method is to design the mandrel of the fixture into a cylindrical shape, but there must be a gap between the outer circle o...

AI Technical Summary

Problems solved by technology

[0005] However, there are still certain defects in the above scheme: 1. When clamping or dismounting the sleeve, it is necessary to disassemble the loading and unloading nut and the clamping cone from the mandrel before the sleeve can be clamped onto the mandrel Or disassembled from the mandrel, the operation is cumbersome, and the efficiency of clamping and disassembly is low; 2. The diameter of the inner hole of the applicable sleeve is limited, and the scope of use is small; 3. The powder debris generated during the grinding process cannot be cleaned in time. impact grinding
