Description

Technical Field

[0001] The utility model relates to the technical field of pipe fitting processing devices, in particular to a thin-wall pipe fitting processing tool. Background Art

[0002] Thin-walled pipe fittings are widely used pipe connectors, commonly used in pipe systems in various fields. Due to the delicate manufacturing process and weak structure of thin-walled pipe fittings, they are easily deformed during processing, so special processing tools are required to clamp and fix them.

[0003] Traditional thin-walled pipe processing clamping tools usually clamp the pipe through an external curved plate to ensure the stability of the pipe during processing. However, this clamping method has some defects. External clamping can easily squeeze and deform the pipe, resulting in reduced processing accuracy. Utility Model Content

[0004] The utility model provides a thin-wall pipe processing tool to solve the above-mentioned problems.

[0005] In order to solve the above technical problems, the technical solution of the utility model is: a thin-walled pipe processing tool, including a center rod, on which two symmetrically arranged pipe fixing mechanisms are slidably provided, the pipe fixing mechanism includes a sleeve slidably mounted on the center rod, an annular plate is fixedly provided at one end of the sleeve close to the center of the center rod, a plurality of telescopic columns are slidably provided on the outer side of the annular plate, a rubber block is fixed at the outer end of the telescopic column, an end of the sleeve away from the annular plate is threadedly connected with an adjusting ring, an end of the adjusting ring close to the annular plate is rotatably provided with a movable ring, and a connecting rod is hinged between the movable ring and the telescopic column.

[0006] Furthermore, both left and right ends of the center rod are provided with splines for fixed connection with the machine tool.

[0007] Furthermore, a sliding groove is provided at the upper end of the central rod, a sliding block is fixedly provided on the inner side surface of the sleeve, and the sliding groove and the sliding block are matched and slidably connected.

[0008] Furthermore, an end of the sleeve away from the annular plate is provided with an external thread, and an inner side surface of the adjusting ring is provided with an internal thread.

[0009] Furthermore, a plurality of grooves are arranged on the side surface of the circular ring plate, a guide rod is fixedly arranged inside the groove, a sliding block 2 is slidingly sleeved on the guide rod, and the telescopic column is fixedly arranged on the sliding block 2.

[0010] Furthermore, a surface of the rubber block in contact with the inner wall of the pipe is arranged in an arc shape.

[0011] Compared with the prior art, the utility model has the following advantages: the utility model adopts two pipe fixing mechanisms slidably arranged on the central rod to fix the pipe from the inside of the pipe, thereby improving the fixing effect and avoiding the problem of easily flattening the pipe when fixing from the outside; the two pipe fixing mechanisms can slide freely on the central rod, thereby adjusting the distance between the two pipe fixing mechanisms to adapt to pipes of different lengths.

[0019] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "inside", "outside", "center", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction structure and operation. Therefore, they should not be understood as limitations on the present invention.

[0020] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "provided with", "installed", "connected", "connected" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, it can be a mechanical connection, it can be an electrical connection, it can be a direct connection, it can be indirectly connected through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0022] Combined with Figure 1 To Attachment Figure 6 A thin-walled pipe processing tool comprises a center rod 1, on which two symmetrically arranged pipe fixing mechanisms are slidably provided, the pipe fixing mechanism comprising a sleeve 2 slidably sleeved on the center rod 1, a circular ring plate 3 is fixedly provided on one end of the sleeve 2 close to the center of the center rod 1, a plurality of telescopic columns 4 are slidably provided on the outer side of the circular ring plate 3, a rubber block 5 is fixedly provided on the outer end of the telescopic column 4, and a side of the rubber block 5 in contact with the inner wall of the pipe is arranged in an arc shape, an end of the sleeve 2 away from the circular ring plate 3 is threadedly connected with an adjusting ring 6, an end of the sleeve 2 away from the circular ring plate 3 is provided with an external thread, an inner side surface of the adjusting ring 6 is provided with an internal thread, an end of the adjusting ring 6 close to the circular ring plate 3 is rotatably provided with a movable ring 7, and a connecting rod 8 is hinged between the movable ring 7 and the telescopic column 4.
