[0026] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0030] When punching holes in metal pipes, a punching device is generally used to fix the pipe on a fixture, 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 uniform intervals, it is necessary to pre-plan the positions of the holes on the outer peripheral surface of the metal pipe in advance, and then use the punching device to punch holes in the metal pipe in sequence. In this way, the punching efficiency is low, and the punching accuracy is easily reduced due to manual operation. Compared with the prior art, the present application uses a rotary alignment component to rotate and position the metal pipe located in the positioning fixture, and then multiple hydraulic punching machines punch holes in the metal pipe at the same time. Finally, the rotary alignment component transfers the metal pipe that has completed the punching process to the collection component for unloading and collection. The entire punching process is automated, and the punching efficiency is high, saving time and effort.

[0031] like Figures 1 to 3 As shown, an embodiment of the present application provides an automatic punching device for metal pipes, including: a machine platform 100, a punching assembly 200, a rotation alignment assembly 300 and a collection assembly 400.

[0032] Among them, the machine 100; the punching assembly 200, including a positioning fixture 210 and a hydraulic punching machine 220, the positioning fixture 210 is arranged on the machine 100, the positioning fixture 210 has a positioning groove and a positioning shaft, the positioning shaft is located at the central axis position of the positioning groove, the hydraulic punching machine 220 has four and are spaced apart on the side of the positioning fixture 210, and the punching knife of the hydraulic punching machine 220 can extend into the positioning groove; the rotation alignment assembly 300, including a rotating base, a lifting linear motor 310, a lifting seat 320, a buffer seat 330, a buffer spring 340, a rotating mechanism 350 and a clamping mechanism 360, the rotating base is arranged on one side of the positioning fixture 210, the lifting linear motor 310 is connected to the output end of the rotating base, the lifting seat 320 is connected to the output end of the lifting linear motor 310, the buffer seat 330 is movably arranged on the lifting seat 320, the buffer spring 340 is connected between the buffer seat 330 and the lifting seat 320, the rotating mechanism 350 is arranged on the buffer seat 330, and the clamping mechanism 360 is connected to the rotating mechanism 350; the collecting component 400 is located on one side of the machine 100.

[0033] The rotating mechanism 350 includes a rotating motor 351, a coupling 352, a rotating shaft 353 and a rotating frame 354. The rotating motor 351 is arranged on the buffer seat 330. The output end of the rotating motor 351 is connected to the rotating shaft 353 through the coupling 352. The rotating frame 354 is connected to the rotating shaft 353. The clamping mechanism 360 is arranged on the rotating frame 354.

[0034] The clamping mechanism 360 includes a clamping air gripper and a clamping block 361 connected to the output end of the clamping air gripper. The clamping air gripper is disposed on the rotating frame 354 .

[0035] The collecting assembly 400 includes a material discharge channel and a collecting box. The collecting box is disposed at one side of the machine 100 , and the material discharge channel is disposed between the machine 100 and the collecting box.

[0036] like Figures 1 to 3 As shown, in some embodiments, the positioning fixture 210 has a plurality of through slots connected to the positioning slots, and the punching knife of the hydraulic punching machine 220 can be movably disposed in the through slots. The extending direction of the positioning slots is perpendicular to the extending direction of the through slots.

[0037] The through groove can be a circular groove or a square groove, which is not specifically limited here. The extending direction of the positioning groove is perpendicular to the extending direction of the through groove, so that the punching knife of the hydraulic punching machine 220 can smoothly enter the positioning groove to complete the punching, which is convenient for punching.

[0038] like Figures 1 to 3 As shown, in some embodiments, the positioning shaft is cylindrical. This arrangement makes it convenient for the metal pipe to be sleeved on the positioning shaft.

[0039] like Figures 1 to 3 As shown, in some embodiments, a punching angle locator 110 is provided on one side of the positioning fixture 210. By providing the punching angle locator 110, the position of the metal pipe in the positioning fixture 210 is determined, thereby achieving accurate positioning of the metal pipe.

[0040] When the automatic punching device for metal pipes is working, the metal pipe is placed in the positioning groove of the positioning fixture 210 and sleeved on the positioning shaft. The lifting linear motor 310 drives the lifting seat 320 to move downward, so that the clamping block 361 on the clamping air claw clamps the metal pipe. The lifting linear motor 310 drives the lifting seat 320 to move upward, so that the metal pipe is exposed from the positioning fixture 210, and then the punching angle locator 110 locates the position of the metal pipe, and drives the rotating motor 351 to work, and the rotating motor 351 drives the rotating frame 354 to rotate, and the clamping air claw rotates accordingly, so that the metal pipe rotates to the correct processing angle. When the metal pipe is adjusted to the correct processing angle, the lifting linear motor 310 drives the lifting seat 320 to move downward, and the buffer seat 330, the rotating mechanism 350 and the clamping mechanism 360 move downward, so that the metal pipe is re-mounted on the positioning shaft. In addition, the lifting linear motor 310 continues to move downward, and the rotating mechanism 350 applies a downward force to the metal pipe, so that the metal pipe is pressed against the positioning shaft. The four hydraulic punching machines 220 work simultaneously to punch holes in the metal pipe. After the punching is completed, the metal pipe is separated from the positioning fixture 210 under the drive of the lifting linear motor 310, and the rotating base drives the lifting linear motor 310 to rotate, so that the clamping mechanism 360 drives the metal pipe to move above the collection component 400. The clamping mechanism 360 releases the clamping block 361, so that the metal pipe falls into the collection component 400.

[0041] 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.
