Description

Technical Field

[0001] The utility model relates to the technical field of pipe parts processing, in particular to a flexible transfer tooling which can broaden the support range of a machine tool top and reduce the rotation and shaking of pipe parts. Background Art

[0002] Pipe parts are widely used in various industries and equipment. When processing the outer wall of pipe parts, a machine tool with a three-jaw chuck is usually used to drive the pipe to rotate for subsequent processing. However, when the length of the pipe increases, the non-chuck clamping part will shake during the rotation process. The farther away from the clamping end, the more significant the rotation shake. The usual solution is to use a top to support the non-chuck clamping end of the pipe. The machine tool ejector rotates with the pipe while supporting the pipe, which has the effect of reducing the shaking of the pipe. However, in the actual processing of pipe parts, it is found that the diameter of pipes varies, while the range of pipe sizes that the top can support is very limited. The diameter of the top end is too small to support the pipe to be processed. At the same time, the machine tool top contains rotating devices such as bearings, which are complicated to manufacture and have a long preparation cycle. The cost of customizing a top of a specific size is expensive. The above reasons also make it impossible to customize suitable tops for pipes of various sizes. Utility Model Content

[0003] In order to solve the above technical problems, the utility model proposes a flexible transfer tooling which broadens the support range of the machine tool center and reduces the rotation and shaking of the pipe fittings.

[0004] The technical problem to be solved by the utility model is achieved by the following technical solutions:

[0005] A flexible transfer tooling is provided to broaden the support range of the machine tool center and reduce the rotation and shaking of the pipe fittings. The overall structure is tubular. One end of the tooling is a flexible support end. The outer surface of the flexible support end is sandblasted to increase the friction and strengthen the cooperation with the inner wall of the pipe fitting to be processed to achieve connection and support for the pipe fitting to be processed. The other end of the tooling is provided with a center action end. The center action end is a conical structure and cooperates with the machine tool center.

[0006] As a further improvement of the utility model, the tooling is entirely made of 316 stainless steel.

[0007] As a further improvement of the utility model, the flexible support end is provided with a plurality of flexible support teeth equidistantly distributed in the circumferential direction.

[0008] As a further improvement of the present invention, the distances between the flexible supporting teeth are equal and consistent with the width of the flexible supporting teeth.

[0009] As a further improvement of the utility model, the wall thickness of the tooling is 0.8 mm, and the outer diameter is 1.6 mm larger than the inner diameter of the pipe to be processed.

[0010] As a further improvement of the present invention, the top inclination angle θ1 of the working end of the center is consistent with the end angle θ2 of the machine tool center.

[0011] The beneficial effects of the utility model are:

[0012] The utility model provides a flexible transfer tooling for broadening the support range of machine tool vertices and reducing the rotation and shaking of pipe fittings, comprising a vertices action end and a flexible support end, wherein the vertices action end is connected to the machine tool vertices, expanding the size range of pipe fittings that the machine tool vertices can support. With the help of the tooling, small-sized vertices can support pipe fittings with larger diameters, avoiding the purchase and customization of larger-sized machine tool vertices, and reducing the cost of use. At the same time, the flexible support end of the tooling has flexible support teeth, which play a role of elastic support and fixation for the pipe fittings to be processed, avoiding the problem of deformation of the ends of the processed pipe fittings due to support clamping. The tooling is made of 316 stainless steel, with simple production cost, easy use, and good engineering application prospects. BRIEF DESCRIPTION OF THE DRAWINGS

In this embodiment, there are 32 groups of flexible support teeth 111, and the distances between the flexible support teeth 111 are equal and consistent with the width of the flexible support teeth 111. The other end of the tooling is provided with a top action end 12, which is a conical structure and cooperates with the machine tool top 2. The structure of the machine tool top 2 is as follows: Figure 3 As shown, the top inclination angle θ1 of the center action end 12 is consistent with the end angle θ2 of the machine tool center 2.

[0023] The working principle and use process of this utility model:

[0024] When in use, first clamp the pipe 4 to be processed on the motor 5 with a three-jaw chuck, then insert the flexible support end 11 with flexible support teeth 111 on the flexible transfer tool 1 into the pipe 4 to be processed, press the end of the machine tool top 2 installed on the top fixture 3 against the top action end 12 on the flexible transfer tool 1, adjust the distance between the top fixture 3 and the motor 5 with a three-jaw chuck, so that the machine tool top 2 and the flexible transfer tool 1 and the pipe 4 to be processed fit tightly. Figure 4 and Figure 5 As shown, finally, the motor 5 with the three-jaw chuck rotates to drive the pipe 4 to be processed to rotate, and then the subsequent processing of the pipe is carried out.
