[0028] When punching holes in metal pipes, a punching device is generally used to fix the pipe on a jig, and the operator manually controls the punching device to punch holes on the outer peripheral surface of the pipe. If it is necessary to punch holes in the metal pipe at even intervals, it is necessary to pre-plan the punching positions on the outer peripheral surface of the metal pipe in advance, and then put it into the jig, and manually adjust the planned punching positions to the hydraulic punching machine. In this way, the manual adjustment efficiency is low, and the manual adjustment accuracy is low, which can easily lead to poor punching accuracy. Compared with the prior art, the present rotary positioning device can make the clamping assembly move up and down through the lifting assembly, so that the metal pipe can enter or leave the positioning jig. At the same time, the rotating assembly allows the clamping assembly to rotate a certain angle to realize the automatic adjustment of the angle of the metal pipe, thereby improving the position adjustment efficiency of the metal pipe, thereby ensuring the punching accuracy of the metal pipe.

[0029] like Figure 1 As shown, an embodiment of the present application provides a rotation positioning device suitable for punching processing, including: a machine platform, a lifting assembly 100, a buffer assembly 200, a rotation assembly 300 and a clamping assembly 400.

[0030] The machine has a positioning fixture. A punching angle locator is provided on one side of the positioning fixture, and the punching angle locator is used to confirm the position of the metal pipe. Exemplarily, when the punching angle locator detects that the position of the metal pipe clamped by the clamping assembly 400 is incorrect, the punching angle locator sends a signal to the controller. The controller drives the rotating motor 320 described below to work. The rotating motor 320 drives the rotating frame 350 to rotate, so that the clamping assembly 400 rotates, and further rotates the metal pipe, and then adjusts it to the correct punching position.

[0031] The lifting assembly 100 includes a lifting linear motor 110 and a lifting seat 120. The lifting linear motor 110 is arranged on one side of the positioning fixture. The lifting seat 120 is connected to the output end of the lifting linear motor 110. The lifting seat 120 has a first stop block 130 and a second stop block 140 that are relatively arranged. A buffer space is formed between the first stop block 130 and the second stop block 140.

[0032] The lifting linear motor 110 can drive the lifting seat 120 to move up and down, thereby synchronously driving the buffer assembly 200, the rotating assembly 300 and the clamping assembly 400 to move up and down, so as to enable the metal pipe to enter or leave the positioning fixture.

[0033] A buffer space is formed between the first stopper 130 and the second stopper 140 on the lifting seat 120 , thereby playing a role of buffering the lifting seat 120 .

[0034] The buffer assembly 200 includes a buffer slide 210, a buffer spring 220 and an extension connector 230. The buffer slide 210 is movably disposed in the buffer space. The buffer spring 220 is connected between the buffer slide 210 and the first stopper 130. The extension connector 230 is connected to the surface of the buffer slide 210 facing away from the lifting seat 120.

[0035] When the metal pipe completely enters the positioning fixture, in order to give the metal pipe a vertical downward force so that the metal pipe is pressed on the positioning fixture, the lifting seat 120 moves downward relative to the buffer slide 210, thereby compressing the buffer spring 220, thereby playing a buffering role and avoiding hard contact between the lifting seat 120 and the buffer slide 210.

[0036] The rotating assembly 300 includes a support base 310, a rotating motor 320, a coupling 330, a rotating shaft 340 and a rotating frame 350. The support base 310 is fixed to the extension connector 230. The rotating motor 320, the coupling 330 and the rotating shaft 340 are all arranged on the support base 310. The output end of the rotating motor 320 is connected to the rotating shaft 340 through the coupling 330. The rotating frame 350 is connected to the rotating shaft 340.

[0037] The clamping assembly 400 is disposed on the rotating frame 350 .

[0038] like Figure 1 As shown, in some embodiments, the moving direction of the output end of the lifting linear motor 110 is parallel to the rotating shaft 340 of the output end of the rotating motor 320. With such a configuration, the output end of the lifting linear motor 110 can drive the rotating assembly 300 to move up and down, so that the metal pipe is separated from the positioning fixture and aligned with the punching angle locator. Then, the rotating motor 320 can drive the metal pipe to rotate, thereby adjusting the position of the metal pipe so that the metal pipe is in the correct punching position.

[0039] like Figure 1 As shown, in some embodiments, the buffer assembly 200 further includes a guide rail and a slider, the guide rail is arranged in the buffer space, the length direction of the guide rail is the same as the moving direction of the output end of the lifting linear motor 110, the slider is slidably connected to the guide rail, and the slider is connected to the buffer slide 210. Through the cooperation of the guide rail and the slider, the buffer slide 210 can stably slide relative to the lifting seat 120.

[0040] like Figure 1 As shown, in some embodiments, the extension connector 230 includes a first connection portion, an extension portion, and a second connection portion connected in sequence, the first connection portion is connected to the buffer slide 210, and the second connection portion is connected to the support seat 310. By providing the extension portion, the distance between the lifting linear motor 110 and the rotating motor 320 is increased, so that the clamping assembly 400 can face the positioning fixture.

[0041] like Figure 1 As shown, in some embodiments, the rotating frame 350 has a receiving space, and the clamping assembly 400 includes a clamping air claw and a claw block 410. The clamping air claw is arranged in the receiving space, and the claw block 410 is connected to both output ends of the clamping air claw.

[0042] By accommodating the clamping air gripper in the accommodating space, when the rotating frame 350 rotates, the connection stability between the clamping air gripper and the rotating frame 350 is improved.

[0043] The working principle of the rotary positioning device of the embodiment of the present application is as follows: the metal pipe is placed in the positioning fixture. The clamping claw uses the claw block 410 to clamp the metal pipe, and is driven by the lifting linear motor 110 to detach from the positioning fixture, so that the metal pipe is aligned with the punching angle locator. The rotating motor 320 drives the rotating frame 350 to rotate, so that the clamping claw rotates, and then adjusts the metal pipe to the correct processing position. Driven by the lifting linear motor 110, the metal pipe re-enters the positioning fixture and is pressed from top to bottom by the clamping assembly 400 to complete the positioning.

[0044] The above are only preferred embodiments of the present application, and do not constitute any formal limitation on the present application. Any technician familiar with the art can use the above disclosed methods and technical contents to make many possible changes and modifications to the technical solution of the present application without departing from the scope of the technical solution of the present application, or modify it into an equivalent embodiment of equivalent changes. Therefore, all equivalent changes made according to the shape, structure and principle of the present application without departing from the content of the technical solution of the present application should be included in the protection scope of the present application.
