It solves the shortcomings of flame cutting, grinder grinding and other operating processes such as irregular angles, rough slopes, and high working noise. It has the advantages of easy operation, standard angles, and smooth surfaces.

[0003] The patent with publication number CN218016111U in the prior art discloses a portable pipe beveling machine, which can clamp and restrict the pipe through the mutual cooperation of a fixed plate, a clamping plate, a push rod and a threaded groove, thereby preventing the pipe mouth from sliding during the processing, and solving the problem of insufficient clamping of the pipe and easy tilting of the pipe angle. However, when using it, the staff needs to rotate the two push rods in sequence to clamp and restrict the pipe. During the clamping process, it is easy for the clamped pipe and the cutting knife to be misaligned due to the different moving distances of the two push rods, which will lead to inaccurate beveling processing and the practicality needs to be improved. Therefore, in order to solve the above problems, the present application proposes a pipe beveling machine. Utility Model Content

[0004] The purpose of the present application is to provide a pipe beveling machine to solve the problem mentioned in the background technology that during the clamping process, the clamped pipe and the cutting knife may be misaligned due to the different moving distances of the two push rods, resulting in inaccurate beveling processing.

When the control hand wheel is turned, the two bidirectional screws are driven to rotate together through the hexagonal connecting rod, the control rotating rod, the transmission sprocket, the transmission chain, the active bevel gear, and the driven bevel gear. The rotation of the bidirectional screw drives the two arc-shaped clamping plates to move toward or away from each other through the moving block, thereby achieving the purpose of clamping and fixing the pipe at one time. The clamped and fixed pipe is concentric with the output end of the rotating motor, which effectively reduces the misalignment between the clamped pipe and the groove cutter, ensuring the accuracy of the pipe groove processing, simple and convenient operation, and good practicality.

[0014] 2. In the utility model, when the control hand wheel is pulled, the locking rod will be driven to move out of the locking socket. At this time, the control hand wheel can be rotated to perform the clamping operation. When the control hand wheel is released, the elastic force of the reset spring will squeeze and push the control hand wheel to automatically reset, and drive the locking rod to automatically move into the locking socket to lock the control hand wheel so that it cannot rotate. This effectively reduces the situation where the pipeline becomes loose due to accidentally touching the control hand wheel during processing, and has good stability during use.

[0023] By means of the above structure, when the control hand wheel 15 is rotated, the control rotating rod 9 will be driven to rotate through the hexagonal connecting rod 14. The rotation of the control rotating rod 9 will drive one of the two-way screw rods 6 to rotate synchronously through the gear transmission unit. At this time, under the action of the synchronous rotation unit, the other two-way screw rod 6 will be driven to rotate together. The rotation of the two-way screw rod 6 will drive the two arc-shaped clamping plates 8 to move toward or away from each other through the moving block 7, thereby achieving the purpose of clamping and fixing the pipeline at one time. The clamped and fixed pipeline is concentric with the output end of the rotating motor 3, which effectively reduces the misalignment between the clamped pipeline and the groove cutter 5, ensures the accuracy of the pipeline groove processing, is simple and convenient to operate, and has good practicality.

[0024] As a preferred implementation of this embodiment, the synchronous rotation unit includes two transmission sprockets 10 respectively mounted on the two bidirectional screw rods 6, and a transmission chain 11 is commonly mounted on the two transmission sprockets 10. The advantage of this arrangement is that when one of the bidirectional screw rods 6 rotates, the other bidirectional screw rod 6 is driven to rotate together through the transmission sprocket 10 and the transmission chain 11, thereby achieving the purpose of making the two bidirectional screw rods 6 rotate synchronously.

[0028] As a preferred implementation of this embodiment, anti-skid rubber pads are fixed on the inner arc surfaces of the two arc-shaped clamping plates 8. The advantage of this arrangement is that it can play a certain buffering role when clamping the pipe, effectively reducing the situation where the pipe is clamped, and at the same time it can also increase the friction between the arc-shaped clamping plate 8 and the pipe, making it more stable when clamping.
