[0029] The embodiment of the present application provides a fixture device for pipe processing, such as Figure 1 As shown, it includes a base frame 100, a mounting plate 300, a clamping cylinder 400 and a cutting knife 500, wherein the base frame 100 is a structure for mounting and supporting other components, the mounting plate 300 is a structure for mounting the clamping cylinder 400, the clamping cylinder 400 can clamp the pipe, and the cutting knife 500 can cut the pipe.

[0030] like Figure 1 As shown, the base frame 100 is provided with a guide platform 200, and the guide platform 200 is provided with a guide hole 210. The guide hole 210 extends along the length direction of the base frame 100. The pipe to be cut is inserted into the guide hole 210. The guide hole 210 can guide the pipe so that the pipe moves along the length direction of the base frame 100.

[0031] like Figure 1 As shown, the mounting plate 300 is arranged on the base frame 100, and the mounting plate 300 is rotatably connected with a lead screw 310, which is transmission-connected with a servo motor 320, and an optical axis 330 is arranged on the mounting plate 300, and the optical axis 330 and the lead screw 310 both extend along the length direction of the base frame 100, and the servo motor 320 and the lead screw 310 can provide movement conditions for other components. The servo motor 320 has the advantage of accurate position control accuracy, which is convenient for controlling the moving distance.

[0032] like Figure 1 and Figure 2 As shown, the clamping cylinder 400 is provided with a threaded hole 410 and a through hole 420, the threaded hole 410 cooperates with the screw rod 310, and the through hole 420 cooperates with the optical axis 330. When the servo motor 320 is started, the clamping cylinder 400 can move along the length direction of the base frame 100. The clamping cylinder 400 is provided with a plurality of clamping plates 430, and the plurality of clamping plates 430 are driven by a clamping cylinder 440. The extension and retraction of the clamping cylinder 440 can control the movement of the clamping plates 430, thereby achieving the clamping and loosening of the pipe.

[0033] like Figure 1 As shown, the cutting knife 500 is disposed on the base frame 100 and is located on a side of the guide platform 200 close to the clamping cylinder 400. After the clamping cylinder 400 clamps the pipe and moves to a position, the cutting knife 500 is started to cut the pipe.

[0034] When in use, the pipe to be cut is inserted into the guide hole 210 of the guide platform 200, the clamping cylinder 440 can realize the clamping of the pipe by the clamping cylinder 400 and the clamping plate 430, the servo motor 320 can realize the movement of the entire clamping cylinder 400 along the length direction of the base frame 100, and the servo motor 320 can control the moving distance, so the clamping cylinder 440 and the servo motor 320 can realize the clamping and moving of the pipe to a fixed distance, and then the cutting knife 500 is used to realize cutting. After taking away the cut pipe, the clamping cylinder 440 and the servo motor 320 are controlled to perform the next cutting.

[0035] Compared with the prior art, the pipe processing fixture device can realize the movement of the pipe a fixed distance through the servo motor 320, so that the length of the pipe cut by the cutting knife 500 is fixed, and there is no need for manual measurement or manual pushing of the fixed distance, thereby eliminating the errors caused by manual operation factors, thereby ensuring the length of the cut pipe.

[0036] In some embodiments, Figure 1 As shown, the base frame 100 is provided with a material drop opening 110, and the material drop opening 110 is located in front of the mounting plate 300. The cut pipe is located above the material drop opening 110, and when the clamping cylinder 440 is released, the pipe falls under the action of gravity, and no manual movement is required, which is convenient for use.

[0037] In some embodiments, Figure 1 As shown, a receiving box 120 is provided below the drop port 110, and the falling pipes can fall into the receiving box 120 for easy collection. When the receiving box 120 is full, the receiving box 120 can be moved out and another empty receiving box 120 can be placed.

[0038] In some embodiments, an anti-skid pad is provided on the inner side of the clamping plate 430, which is in direct contact with the pipe, thereby increasing the friction between the pipe and the clamping tube 400 to prevent it from slipping during movement, so that the distance the pipe moves is equal to the distance the clamping tube 400 moves, thereby ensuring the length of the pipe after cutting.

[0039] In some embodiments, a protective layer is provided at the mouth of the clamping cylinder 400 on the side close to the cutting knife 500. When the pipe falls, it may collide with the mouth of the clamping cylinder 400. By providing the protective layer, the pipe can contact the protective layer and avoid direct contact with the clamping cylinder 400, thereby preventing damage to the pipe and ensuring the quality of the pipe after cutting.

[0040] In some embodiments, Figure 3 As shown, the inner wall of the guide cylinder is provided with a guide roller 220, and the pipe contacts the guide roller 220 to avoid contact between the pipe and the inner wall of the guide hole 210, thereby reducing friction and the possibility that the guide hole 210 may cause wear on the outer wall of the pipe.

[0041] In some embodiments, Figure 4 As shown, the cutting knife 500 includes a lifting cylinder 510, a support plate 520, a cutting motor 530 and a disc knife 540. The lifting cylinder 510 is installed on the base frame 100, the support plate 520 is installed on the cylinder rod of the lifting cylinder 510, the disc knife 540 is rotatably connected to the support plate 520, and the cutting motor 530 is transmission-connected to the disc knife 540. The cutting motor 530 can drive the disc knife 540 to rotate, and the lifting cylinder 510 can drive the entire disc knife 540 to rise and fall, thereby facilitating the cutting of the pipe.

[0042] In some embodiments, the pipe processing fixture device also includes a controller, and the servo motor 320, the clamping cylinder 440, the lifting cylinder 510 and the cutting motor 530 are all electrically connected to the controller. The controller can control the servo motor 320, the clamping cylinder 440, the lifting cylinder 510 and the cutting motor 530, so as to facilitate automatic control of the clamping, movement and cutting of the pipe, and realize automatic cutting. For example, the controller controls the servo motor 320 to start, so that the clamping cylinder 400 moves to one end of the pipe, controls the clamping cylinder 440 to clamp, realizes the clamping of the pipe, controls the servo motor 320 to rotate in the opposite direction, realizes the movement of the pipe by a fixed distance, and then controls the lifting cylinder 510 and the cutting motor 530 to realize the cutting of the pipe, controls the clamping cylinder 440 to release, and the cut pipe falls. In this way, the automatic cutting of the pipe can be realized.
