Abstract

The invention discloses a tapered bush part processing auxiliary device and a use method. The tapered bush part processing auxiliary device comprises a dead centre, a fixing screw, a heart jacket, a mandrel, a clamping gasket and a hexagonal nut; the heart jacket and the mandrel are fixed through the fixing screw; the mandrel is sleeved with a tapered bush part, and the tapered bush part is fixed to the mandrel through the hexagonal nut and the clamping gasket; and according to the tapered bush part processing auxiliary device and the use method, the device can be used for processing the tapered bush part, and the auxiliary device is simple in structure, easy to manufacture, and capable of improving the dimensional accuracy of the part required to be processed; and therefore, the part meeting the quality requirement can be simply and rapidly processed, a special fixture can be prevented from being ordered, the production period is shortened, the processing cost is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a processing auxiliary device for a tapered bushing part and a use method thereof. Background technique [0002] In the field of aerospace manufacturing, it is often necessary to produce tapered bushing parts, but the clamping of tapered bushing parts is difficult. According to the ordinary lathe clamping method, one clamping and one top, the positioning is difficult, and the clamping is turned around twice or even multiple times. In this way, there is a small step surface on the outside of the cone, and the concentricity of the two cones is poor, and the accuracy is poor. Therefore, it is difficult to ensure the coaxiality and precision in repeated clamping and processing, which causes material waste and affects work efficiency. Contents of the invention [0003] In order to solve the technical problems of difficult machining and poor precision of ha...
