In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0041] When drilling holes in the cabinet, the current electrical cabinet hole-punching device has great limitations on the space and drilling angle during the drilling process, because there are other electrical equipment and components in the cabinet. If the worker punches the holes by hand, the position and shape of the holes may deviate. At the same time, when drilling holes in thin cabinet panels, the thrust generated will also affect its flatness. On the one hand, it may cause the size of the holes to deviate, and on the other hand, it may cause damage to the inside of the cabinet, resulting in poor sealing, waterproofing and dustproofing of the cabinet when it is put into daily use, affecting the normal use of the cabinet.

[0042] In this regard, the present application proposes a hole-punching device for an electrical cabinet, which can be fixed in the electrical cabinet through a first suction cup 210 and a second suction cup 310, and during the punching process, the pulling force of the first suction cup 210 and the second suction cup 310 on the cabinet partially offsets the thrust of the electric drill 420, thereby reducing the deformation of the cabinet during the punching process; in addition, by adjusting the flipping angle of the first suction cup 210 and the second suction cup 310 to change the angle of subsequent punching, different punching requirements can be met.

[0043] In addition, the present application also proposes a working method for the above-mentioned electrical cabinet body opening device.

[0044] Reference Figure 1 The electrical cabinet body hole opening device in the embodiment of the first aspect of the present application comprises a support column 100, a first fixing component 200, a second fixing component 300 and a punching component 400. The support column 100 is the main structure of the electrical cabinet body hole opening device, the first fixing component 200 and the second fixing component 300 are both used to fix the support column 100 on the electrical cabinet body, and the punching component 400 is used to punch holes in the electrical cabinet body.

[0045] Specifically, the first fixing assembly 200 includes a first suction cup 210 , which is mounted on the end of the support column 100 through a ball hinge, so that the first suction cup 210 can be flipped around the support column 100 at multiple angles.

[0046] There are multiple second fixing components 300, and they are all distributed in a circular array around the first fixing component 200. The second fixing component 300 includes a second suction cup 310, an extension rod 320 and a telescopic rod 330. The extension rod 320 is installed on the side of the support column 100, and the end of the telescopic rod 330 is connected to the extension rod 320. The second suction cup 310 is installed on the end of the telescopic rod 330 through a ball hinge, so that the extension distance of the second suction cup 310 can be changed when the telescopic rod 330 is extended and retracted, and the second suction cup 310 can be flipped at multiple angles around the telescopic rod 330.

[0047] The punching assembly 400 includes a slider 410 and an electric drill 420 . The slider 410 is slidably connected to the support column 100 and can slide along the support column 100 . The electric drill 420 is installed on the slider 410 and moves with the slider 410 .

[0048] Among them, refer to Figure 2 The first suction cup 210 and the second suction cup 310 are used to be adsorbed on the cabinet body of the electrical cabinet. By adjusting the angles of the first suction cup 210 and the second suction cup 310, the inclination angle of the support column 100 can be adjusted, thereby changing the punching angle. Specifically, when the inclination angle of the support column 100 needs to be changed, the first suction cup 210 can be flipped with the adsorption point between the first suction cup 210 and the cabinet body of the electrical cabinet as the fixed point; in each second fixed component 300, the telescopic rod 330 is correspondingly extended and retracted, and the second suction cup 310 is also flipped accordingly, thereby causing the angle of the electrical cabinet body hole opening device to change. Subsequently, the angle of the first suction cup 210 and the second suction cup 310 can be locked to limit the angle change of the electrical cabinet body hole opening device.

[0049] As for the locking method of the angles of the first suction cup 210 and the second suction cup 310, methods such as top screw locking and ball socket clamping locking in the ball hinge can be used, which are all existing technologies for ball hinge locking and will not be described in detail here.

[0050] Furthermore, the first fixing assembly 200 further includes an elastic member 220, which is mounted on the end of the support column 100, and the first suction cup 210 is connected to the elastic member 220 via a ball hinge. A guide column is provided in the middle of the elastic member 220 to limit the elastic deformation direction thereof to be consistent with the shape direction of the support column 100. The elastic member 220 is designed to absorb the vibration generated during drilling, thereby ensuring that the first suction cup 210 can always be attached to the cabinet body of the electrical cabinet, and preventing the first suction cup 210 from being separated from the cabinet body of the electrical cabinet under vibration during the drilling process, thereby causing a fixing failure.

[0051] Specifically, in the present embodiment, the elastic member 220 is specifically a spring, and elastic members such as a rubber pad and a damping rod may also be used, which will not be described in detail here.

[0052] Further, refer to Figure 3 The support column 100 is provided with a first slide groove 110 , and the slider 410 slides in the first slide groove 110 , thereby achieving a sliding connection relationship between the slider 410 and the support column 100 , and the sliding direction of the slider 410 is limited by the first slide groove 110 .

[0053] Furthermore, the punching assembly 400 further includes a locking member 430, which is mounted on the slider 410 and is used to fix the slider 410 in the first slide groove 110. Specifically, in this embodiment, the locking member 430 is a bolt, and the slider 410 is provided with a threaded hole that can be threadedly connected with the bolt, and the end of the bolt can be exposed from the threaded hole and abut against the bottom of the first slide groove 110. Therefore, when the bolt is tightened, the end of the bolt can extend to the bottom of the first slide groove 110 and abut against it, limiting the slider 410 from sliding further.

[0054] It is easy to understand that the locking member 430 can also adopt a buckle or pin structure to lock the slider 410, which will not be described in detail here.

[0055] Optionally, the end of the telescopic rod 330 is slidably connected to the extension rod 320, and the telescopic rod 330 can slide along the extension rod 320, thereby changing the distance between the second suction cup 310 and the first suction cup 210, so as to better adapt to the component layout in the electrical cabinet and reduce interference with other components.

[0056] Specifically, the extension rod 320 is provided with a second sliding groove 321 , and the end of the telescopic rod 330 slides in the second sliding groove 321 , so that the sliding direction of the telescopic rod 330 is limited by the second sliding groove 321 .

[0057] Optionally, the electrical cabinet body opening device further comprises a base 500 and a mechanical arm 600, the mechanical arm 600 is mounted on the base 500, and the support column 100 is mounted on the end of the mechanical arm 600. Thus, the support of the support column 100 by the base 500 and the mechanical arm 600 can reduce the fixing pressure of the first fixing assembly 200 and the second fixing assembly 300, and increase the installation stability of the electrical cabinet body opening device.

[0058] Furthermore, the electrical cabinet body opening device may further include a rotating mechanism 700 , and the mechanical arm 600 is installed on the base 500 via the rotating mechanism 700 , so that the mechanical arm 600 can rotate on the base 500 .

[0059] Specifically, refer to Figure 4 The base 500 includes a motor 510 and a tripod 520. The base 500 contacts the ground through the tripod 520. The height of each tripod 520 can be adjusted so as to adapt to the uneven bottom surface. The motor 510 is used to drive the rotating mechanism 700 to rotate.

[0060] Reference Figure 5 The rotating mechanism 700 includes a slide rail 710, a limit block 720, a cover plate 730 and a fixed plate 740. The slide rail 710 is annular, the limit block 720 slides in the slide rail 710, the cover plate 730 is connected to the limit block 720 so as to rotate with the sliding of the limit block 720, and the fixed plate 740 is connected to the cover plate 730 and is used to be connected to the bottom of the robot arm 600.

[0061] Furthermore, the mechanical arm 600 includes a first support arm 610 and a second support arm 620 pivotally connected to each other, and the support column 100 is hinged to the second support arm 620 .

[0062] Optionally, the first support arm 610 is specifically a telescopic rod, so that the height of the mechanical arm 600 can be changed. The rotation of the first support arm 610 and the second support arm 620 is completed by a motor.

[0063] The working method for the above-mentioned electrical cabinet opening device in the second embodiment of the present application includes the following steps:

[0064] S100. Install the electric drill 420 on the slider 410 and determine the drilling position of the electric drill 420 on the electrical cabinet body;

[0065] S200. The first suction cup 210 and each second suction cup 310 are adsorbed on the electrical cabinet body;

[0066] S300. Adjust the flip angle of the first suction cup 210 and each second suction cup 310, thereby adjusting the drilling position and drilling angle of the electric drill 420;

[0067] S400. Lock the angles of the first suction cup 210 and each second suction cup 310;

[0068] S500. Turn on the electric drill 420 and drive it to move along the support column 100 until the electric drill 420 successfully drills a hole in the electrical cabinet body;

[0069] S600: Drive the electric drill 420 back, turn off the electric drill 420 and release the first suction cup 210 and each second suction cup 310 from adsorbing the electrical cabinet body, and the drilling is completed.

[0070] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments.
