Turning tools for universal joints

Abstract

The invention belongs to the technical field of machining tools, and particularly relates to a turning tool of a universal joint. The turning tool comprises a columnar tool handle. Two opposite tool rods are arranged at one end of the tool handle. An inward tool bit is arranged at the outer end of each tool rod. A distance adjusting assembly capable of adjusting the distance between the two tool rods is arranged between the tool rods and the tool handle, and the tool rods are connected with the tool handle through the distance adjusting assembly. Compared with the prior art, the turning tool of the universal joint has the beneficial effects that firstly, design is reasonable, the structure is simple, the machining efficiency and the yield are increased, and universal joints of different specifications can be machined; secondly, adjusting is convenient, and the acquisition cost of enterprises is reduced; thirdly, replacement is convenient, and the maintenance cost is reduced; fourthly, mounting is easy, use is convenient, product machining is facilitated, and a machined internal thread and a machined external thread are located on the same concentric circle; and fifthly, the labor intensity of staff is effectively lowered.

Description

technical field [0001] The invention belongs to the technical field of machining tools, in particular to a universal joint turning tool. Background technique [0002] At present, when making PTFE universal joints, first fix the PTFE material on the machine tool, use the outer edge cutter to cut out the thread of the required depth of the universal joint, after the outer edge thread is engraved, and then use the inner edge cutter to carve threads into the tube. This type of operation has the following defects: one is: the work efficiency is low, because the process is complicated, generally speaking, at least two processes of inner and outer edges are needed to complete. The second is that the accuracy is not high. Since the inner and outer edge tools are completed one after another, it is very easy to cause the inner and outer threads to not be on the same concentric circle, and become defective or unqualified products. Even if they can be processed at the same time, they c...

This type of operation has the following defects: one is: the work efficiency is low, because the process is complicated, generally speaking, at least two processes of inner and outer edges are required to complete

The second is that the accuracy is not high. Since the inner and outer edge tools are completed one after another, it is very easy to cause the inner and outer threads to not be on the same concentric circle, and become defective or unqualified products. Even if they can be processed at the same time, they cannot be processed with the same tool. wall thickness universal joint

[0004] Although the above scheme has a good turning effect, the work efficiency is low, and the inner and outer edge tools are completed successively, which can easily cause the inner and outer threads to not be on the same concentric circle, and become defective and unqualified products, which cannot meet the requirements of the manufacturer. The need for large-scale production, and the processing efficiency is low
