[0019] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0020] like Figure 1-Figure 3 As shown, the embodiment of the utility model provides a plastic pipe processing and cutting fixture, comprising:

[0021] Mounting table 1;

[0022] Two clamp assemblies mounted on the mounting platform 1; the clamp assembly comprises a bracket 13 mounted on the mounting platform 1, a fixed arc plate 2 is fixed on the bracket 13, three threaded barrels 6 capable of synchronous rotation are penetrated through the fixed arc plate 2, the three threaded barrels 6 are distributed in an inverted triangle, a movable arc plate 3 driven to move is arranged outside the fixed arc plate 2, three connecting plates 9 are fixed on the movable arc plate 3, a rack plate 8 is fixed on the connecting plate 9, and a gear 7 meshing with the rack plate 8 is fixed on the threaded barrel 6;

[0023] Specific explanation: The bracket 13 is equipped with an electric push rod 4, the output end of which is fixedly connected to the movable arc plate 3. When the electric push rod 4 drives the movable arc plate 3 to move, it can drive the connecting plate 9 and the rack plate 8 to move. The rack plate 8 moves to drive the gear 7 to rotate, thereby driving the three gears 7 to rotate synchronously.

[0024] Among them, the two rack plates 8 located on the upper side are meshed with the upper side of the gear 7, and the two rack plates 8 are arranged close to the end of the fixed arc plate 2, so that the cooperation of the two gears 7 and the rack plates 8 can support the movable arc plate 3 so that it can move stably; in addition, a support roller can also be installed on the mounting platform 1, and the support roller is against the bottom of the movable arc plate 3, which can support the movable arc plate 3, thereby further ensuring the stability of the movable arc plate 3

[0025] The threaded barrel 6 is internally threaded with a screw 12, and a guided arc-shaped clamping plate 5 is fixed on the screw 12. A rubber pad can be fixed on the arc-shaped clamping plate 5 to increase the friction force of clamping the pipe and protect the outer wall of the pipe. Specifically, a first sleeve 10 is fixed on the fixed arc-shaped plate 2, and a second sleeve 11 is slidably connected in the first sleeve 10. The second sleeve 11 is fixedly connected to the arc-shaped clamping plate 5. The arc-shaped clamping plate 5 can be guided by the first sleeve 10 and the second sleeve 11. In this way, when the threaded barrel 6 rotates, the screw 12 will not be driven to rotate together, so that the screw 12 and the arc-shaped clamping plate 5 can be driven to move, and at this time, the first sleeve 10 and the second sleeve 11 move relative to each other;

[0026] The three arc-shaped clamping plates 5 move synchronously to clamp and position the plastic pipe; specifically, since the fixed arc plate 2 and the movable arc plate 3 are both set in an arc shape, the openings of the fixed arc plate 2 and the movable arc plate 3 are set upward, and the pipe is placed on the arc-shaped clamping plate 5 at the bottom through this opening, which is more convenient for placing the pipe; the electric push rod 4 can realize the rotation of the three threaded barrels 6 and the synchronous movement of the three arc-shaped clamping plates 5, and finally the pipe is stably and positively clamped; the electric push rod 4 drives the displacement of the movable arc plate 3 to adjust the distance between the three arc-shaped clamping plates 5, so that pipes of different diameters can be clamped.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
