[0001] This utility model relates to the field of high and low voltage switchgear processing technology, specifically a high and low voltage switchgear grinding and polishing workstation. Background Technology

[0002] A switchgear is an integrated electrical system containing key electrical components such as circuit breakers, disconnectors, load switches, instrument transformers, and various protective devices. It is primarily used for receiving and distributing electrical energy, and for controlling, measuring, protecting, and monitoring power lines. Based on voltage levels, switchgear can be divided into high-voltage switchgear and low-voltage switchgear, collectively referred to as high- and low-voltage switchgear.

[0003] Currently, the enclosures of this type of equipment are generally manufactured using metal sheets assembled together. During the enclosure processing, the surface of the metal sheets needs to be polished to ensure consistency in overall appearance and quality. However, significant technical bottlenecks still exist in the surface treatment stage: traditional methods suffer from insufficient precision in controlling the grinding force and poor surface uniformity, resulting in inconsistent surface quality of the finished product, which in turn affects the overall protective performance and aesthetics of the equipment.

[0010] Furthermore, a dust collection component is installed on the frame, with the dust collection port facing the gap formed between the grinding belt and the conveyor belt.

[0011] The beneficial effects of this utility model are: (1) By precisely adjusting the distance between the drive roller and the conveyor belt, the grinding pressure can be precisely controlled, thereby ensuring that the surface of the high and low voltage switch cabinet is uniformly and delicately ground to meet the process requirements under different working conditions.

[0012] (2) By using the adjusting rod to drive the rotation of the eccentric structure's drive shaft, the position of the drive roller can be accurately changed, thereby adjusting the gap between it and the conveyor belt.

[0018] like Figure 1 As shown, the specific structure of the high and low voltage switchgear grinding and polishing workstation includes a frame 1, which adopts a frame structure. A conveyor belt 2 is located at the lower part of the frame 1. A grinding and polishing assembly 4 is located at the upper part of the frame 1. The height of the conveyor belt 2 relative to the frame 1 is adjustable, meaning the relative position of the conveyor belt 2 and the grinding and polishing assembly 4 is adjustable to adapt to different processing and technological requirements. A grinding belt 5 is wrapped around the grinding and polishing assembly 4, and the grinding and polishing assembly 4 can drive the grinding belt 5 to rotate. A dust extraction assembly 3 is installed on the frame 1, with its suction port facing the gap between the grinding belt 5 and the conveyor belt 2, effectively extracting dust generated during the grinding process.

[0019] like Figure 2 , 3As shown, the polishing assembly 4 includes a driven roller assembly 44 and a driven roller assembly 45 arranged at intervals. In a specific embodiment, the driven roller assembly 45 is mounted on the lower fixed member 41, the driven roller assembly 44 is mounted on the upper fixed member 43, and a connecting member 42 connects the lower fixed member 41 and the upper fixed member 43. The lower fixed member 41 is fixedly connected to the frame 1. The connecting member 42 can adjust the distance between the lower fixed member 41 and the upper fixed member 43, thereby allowing the driven roller assembly 44 and the driven roller assembly 45 to tension the polishing belt 5.

[0020] like Figure 5 , 7 As shown, the specific structure of the drive roller assembly 45 includes a drive roller 451 and a drive shaft 452 for mounting the drive roller 451. A connecting flange 453 is rotatably mounted on a lower fixing member 41 and fixedly connected to a central shaft 4521. A connecting arm 454 is mounted on the connecting flange 453. An adjusting rod 455 is hinged at both ends to the connecting arm 454 and the lower fixing member 41, and its length is adjustable. The adjustable rod 455 is existing technology. The specific structure of the drive shaft 452 includes a central shaft 4521 and an eccentric shaft 4522 offset from the axis of the central shaft 4521. The drive roller 451 is rotatably mounted on the eccentric shaft 4522. By adjusting the length of the adjusting rod 455, the connecting flange 453 can be driven to rotate via the connecting arm 454, thereby causing the drive shaft 452 to rotate. The eccentric shaft 4522 on the drive shaft 452 can be finely adjusted in height, thereby adjusting the height of the drive roller 451 and precisely controlling the gap between the drive roller 451 and the conveyor belt 2. This allows for precise control of the grinding pressure, ensuring uniform and fine grinding of the high and low voltage switchgear surface, adapting to the process requirements under different working conditions. Furthermore, by using the adjusting rod 455 to drive the eccentric drive shaft 452 to rotate, the position of the drive roller 451 can be accurately changed, thus finely adjusting the gap between it and the conveyor belt 2. This structure is not only easy to operate but also possesses high adjustment accuracy and good mechanical stability, which is beneficial for maintaining stable grinding quality over the long term.

[0021] like Figure 4 , 6As shown, the driven roller assembly 44 includes a driven roller 441 and a driven shaft 442 for mounting the driven roller 441. A stud 445 is fixedly mounted on the upper fixing member 43. One end of the driven shaft 442 is hinged to the upper fixing member 43, allowing the driven shaft 442 to swing longitudinally relative to the upper fixing member 43. A hinge block 443 is mounted on the other end of the driven shaft 442, and the hinge block 443 is hinged to the driven shaft 442 via a transverse rotating shaft. The hinge block 443 is sleeved on the stud 445. Two positioning nuts 444 are threadedly connected to the stud 445, and the hinge block 443 is positioned between the two positioning nuts 444. By adjusting the positioning nuts 444, the tilt angle of the driven roller 441 can be changed. This function effectively prevents the grinding belt 5 from deviating during operation and facilitates quick disassembly and replacement of the grinding belt 5 by operators, improving maintenance efficiency and equipment applicability.
