Description

Technical Field

[0001] The utility model relates to the technical field of machine tool processing, in particular to an anti-deformation processing fixture. Background Art

[0002] Machine tool processing refers to the process of using a machine tool to ensure the relative motion relationship between the tool and the fixture, and using the tool (or other tools) to process the workpiece installed on the fixture. However, this process is not necessarily cutting processing, it may also be pressure processing. For example, knurling or spinning on a lathe.

[0003] When processing pipe materials, the pipe material needs to be positioned first. The existing clamps generally position the pipe material from the outside. If the force during the positioning process is too large, it is easy to cause depression of the pipe wall, causing the pipe material to deform. If the force during the positioning process is too small, it will affect the positioning effect and reduce the stability of the pipe material.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0005] In view of the above background technology, the existing technology has the disadvantages that the force of pipe positioning is not well controlled, which may easily lead to the pipe being too tight or too loose during positioning.

[0006] The cam is connected with the motor at the front side of the motor, and the motor is rotatably connected with the output shaft at the front side of the motor. The outer circumferential surface of the output shaft is threadedly connected with a threaded tube, and the outer circumferential surface of the threaded tube is fixedly connected with four racks. The front side of the back plate is fixedly connected with two fixing plates, and the front side of the back plate is provided with a fixing frame, and each of the front sides of the fixing plate is fixedly connected with the back side of the fixing frame.

[0007] Furthermore, a limiting ring is provided on one side of the fixing plate close to the output shaft, the outer circumferential surface of the output shaft is rotatably connected to the inner circumferential surface of the limiting ring, and the inner diameter of the contact portion between the limiting ring and the output shaft is smaller than the outer diameter of the output shaft.

[0008] Furthermore, two support plates are fixedly connected to the front side of the back plate, and the upper surface of each support plate is fixedly connected to the bottom surface of the fixed plate.

[0009] Furthermore, two limiting plates are fixedly connected to the outer circumferential surface of the threaded tube, and the outer surface of each limiting plate is slidably connected to the inside of the fixed plate.

[0010] Furthermore, a gear is provided on the outer circumferential surface of the second rotating rod, and the gear is meshed with the rack.

[0011] Furthermore, the inner diameter of the contact portion between the base and the swing arm 1 is smaller than the outer diameter of the swing arm 1.

[0012] Furthermore, the inner diameter of the contact portion between the base and the second swing arm is smaller than the outer diameter of the second swing arm.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The utility model drives the gear to rotate during the movement of the rack, so that the swing arm 2 drives the base to maintain horizontal lifting under the restriction of the swing arm 1, and then drives the positioning plate to be retracted and extended, so as to achieve the effect of positioning the pipe from the inside to avoid the pipe from being dented and deformed, and solves the problem that the existing clamps cannot control the positioning force when positioning the pipe from the outside, which is easy to cause damage to the pipe.

[0015] 2. The utility model has a simple structure and is easy to use. It can position the inner wall of the pipe by supporting it, avoiding the pipe wall from being stressed from the outside and causing depression, which would damage and deform the pipe, affect the quality of the pipe, and cause economic losses. It can position and process pipes of various sizes, increasing the flexibility and practicality of the fixture. BRIEF DESCRIPTION OF THE DRAWINGS

The outer diameter of 11, the inner diameter of the contact part between the base 12 and the swing arm 17 is smaller than the outer diameter of the swing arm 17, which restricts the base 12 to prevent the base 12 from sliding and deviating, and increases the stability of the movement of the positioning plate 13. The top of the swing arm 11 is rotatably plugged with the inside of the base 12, and the internal rotation of the fixed frame 9 is plugged with four rotating rods 2 16. The outer circumferential surface of each rotating rod 2 16 is fixedly sleeved with the swing arm 2 17, and the top of the swing arm 2 17 is rotatably plugged with the inside of the base 12.

[0026] See also Figure 2 , Figure 3 , Figure 4 The outer circumferential surface of the rotating rod 16 is provided with a gear 14, and the gear 14 is meshed with the rack 7, so that the rack 7 drives the rotating rod 16 to rotate through the gear 14 during the movement, thereby retracting and extending the positioning plate 13.
