DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] like Figures 1 to 5 As shown, a punching device for processing a wheel house outer plate 91 comprises a workbench 2, wherein the workbench 2 has a positioning column 3, a first annular guide rail 21 arranged around the positioning column 3 with the positioning column 3 as the center, a first annular slide hole 22 opened at the center of the first guide rail, a second annular slide hole 23 and a punching mechanism, and a plurality of fixing clamps 24 for clamping one side of the arc-shaped portion of the wheel house outer plate 91 are installed on the positioning column 3;

[0022] The punching mechanism includes a punching seat 41, a fixed pressure plate 42, a second drive motor 43, a punching drill bit 44, a connecting column 45, a sliding block 46 and a receiving basin 47, wherein the punching seat 41 is slidably connected to the first annular guide rail 21, and the punching seat 41 has a fixed frame 51 on the side close to the wheel cover outer plate 91, and the first drive motor 52 is symmetrically installed on the fixed frame 51, and the output shaft of the first drive motor 52 is connected with a screw rod 53 in a transmission manner, and a second guide rail 54 is also installed in the fixed frame 51, and a fixed pressure plate 42 is slidably arranged on the second guide rail 54, and the fixed pressure plate 42 is connected to the screw rod 53, and the fixed pressure plate 42 abuts against the upper surface of the wheel cover outer plate 91 and has a first through hole 421; a punching frame 411 is also installed on the punching seat 41, and the second drive motor 43 is installed on the punching frame 411, and the punching drill bit 44 is connected with the output shaft of the second drive motor 43;

[0023] The connecting column 45 is installed at the bottom of the punching seat 41 and passes through the first annular sliding hole 22. A sliding block 46 is fixed to the end of the connecting column 45 away from the punching seat 41. A second annular guide rail 61 is installed at the bottom of the workbench 2. The sliding block 46 passes through the second annular guide rail 61 and slides with the second annular guide rail 61. A material receiving basin 47 is threadedly connected to the sliding block 46, and the material receiving basin 47 has a material receiving groove 471.

[0024] A moving handle 9 is also installed on one side of the punching seat 41 .

[0025] In the present invention, the fixing clamp 24 is a prior art device that can clamp a workpiece.

[0026] By adopting the above structure, when punching and stamping the wheel cover outer panel 91, the wheel cover outer panel 91 can be placed on the workbench 2, and one side of the arc-shaped portion of the wheel cover outer panel 91 can be clamped and fixed by a plurality of fixing clips 24 on the positioning column 3, which is beneficial to greatly reduce the vibration and shaking of the wheel cover outer panel 91 during punching. At the same time, the operator moves the punching seat 41 by holding the moving handle 9 until the punching drill bit 44 on the punching seat 41 is aligned with the predetermined punching position on the wheel cover outer panel 91. At the same time, the first drive motor 52 is started to drive the screw rod 53 to rotate. The screw rod 53 can convert the rotary motion into a linear motion, so that the fixed pressure plate 42 slidingly arranged on the second guide rail 54 can move up or down on the screw rod 53. The fixed pressure plate 42 moves up or down when punching is required. It is lowered before the hole is made to rest against the top of the wheel arch outer panel 91, and is pressed and fixed, and then punching is performed, which is beneficial to better press the wheel arch outer panel 91, so that the wheel arch outer panel 91 is not easy to vibrate and swing or deviate from the predetermined punching position during punching, thereby improving the quality of punching; when punching the wheel arch outer panel 91, a material receiving basin 47 is also provided directly below it, and the metal debris generated when the punching drill 44 punches the wheel arch outer panel 91 will fall into the material receiving groove 471 of the material receiving basin 47, and when the punching seat 41 is moved, the material receiving basin 47 can also be moved synchronously, ensuring that the material receiving basin 47 can always collect the metal debris that falls during punching, which is beneficial to the convenient collection of metal debris, making the device neat and beautiful, and reducing device failure and damage caused by accumulation of metal debris.

[0027] Specifically, if Figures 1 to 5 As shown, the first annular guide rail 21 has a first sliding portion 71 , the bottom of the punching seat 41 has a first sliding groove 72 , and the first sliding portion 71 is slidably matched with the first sliding groove 72 .

[0028] With the above structure, the first sliding portion 71 and the first sliding groove 72 slide together, which is conducive to more convenient movement of the punching seat 41 and the components on the punching seat 41, convenient and sensitive adjustment, and better practicality.

[0029] like Figures 1 to 5 As shown, the punching drill bit 44 is aligned with, from top to bottom, the first through hole 421 on the fixed pressure plate 42, the wheel cover outer plate 91, the second annular sliding hole 23 and the material receiving groove 471 of the material receiving basin 47.

[0030] Through the above structure, when punching the wheel cover outer plate 91, a receiving basin 47 is also provided directly below it. The metal debris generated when the punching drill 44 punches the wheel cover outer plate 91 will fall into the receiving groove 471 of the receiving basin 47 through the wheel cover outer plate 91 and the second annular sliding hole 23 in turn, which is conducive to the convenient collection of metal debris, making the device neat and beautiful, and reducing the device failure and damage caused by the accumulation of metal debris.

[0031] like Figures 1 to 5 As shown, a mounting column 472 is installed on one side of the receiving basin 47, a threaded hole 473 is opened in the center of the mounting column 472, a threaded column 461 is installed on the bottom of the sliding block 46, the surface of the threaded column 461 has an external thread, and the threaded column 461 is threadedly connected with the threaded hole 473 of the mounting column 472.

[0032] By threading the mounting post 472 of the receiving basin 47 onto the threaded post 461 at the bottom of the sliding block 46, the receiving basin 47 can be detachably connected to the sliding block 46. If metal debris in the receiving groove 471 of the receiving basin 47 needs to be cleaned, the receiving basin 47 can be removed, and the receiving basin 47 can be screwed on again after the metal debris is cleaned, which is convenient for disassembly and assembly and has strong practicality.

[0033] like Figures 1 to 5 As shown, the second guide rail 54 has a second sliding portion 81, the fixed pressing plate 42 has a second sliding groove 82, and the second sliding portion 81 is slidably matched with the second sliding groove 82. The second sliding portion 81 and the second sliding groove 82 are slidably matched, which is conducive to more convenient lifting and lowering of the fixed pressing plate 42 in the fixed frame 51.

[0034] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
