Description

Technical Field

[0001] This utility model relates to the field of electrical equipment processing technology, and in particular to a precision grinding device for busbar lap joint surfaces in power distribution cabinets. Background Technology

[0002] In the manufacturing process of distribution cabinets, the quality of the busbar's lap surface, as a conductive connector, directly affects the cabinet's conductivity and safety performance. The busbar lap surface needs sufficient flatness and smoothness to reduce contact resistance and prevent overheating due to poor contact.

[0003] In existing grinding devices, the grinding of busbar lap surfaces is usually done manually with hand-held sandpaper or an angle grinder. This method cannot properly adjust the longitudinal height and lateral position of the grinding wheel, resulting in low grinding precision and inability to accurately control the grinding depth. This can easily lead to excessive consumption of busbar material or insufficient grinding. In actual use, manual operation is difficult to adapt to different sizes of busbar lap surfaces within the standard range, and it is also impossible to optimize the cutting angle in a targeted manner. Therefore, we propose a precision grinding device for busbar lap surfaces in distribution cabinets. Utility Model Content

[0020] Please see the appendix Figure 1 and appendix Figure 3A precision grinding device for busbar lap surfaces in a power distribution cabinet includes a worktable 1 and a conveyor frame 4. An adjustment assembly 2 is located behind the worktable 1. The adjustment assembly 2 includes a motor 201, a driven bevel gear 208, a moving block 214, and a limit rod 217. The motor 201 is connected to a drive pulley 203 via a first rotating rod 202. The drive pulley 203 is connected to a driven pulley 205 via a belt 204. The driven pulley 205 is connected to a drive bevel gear 207 via a second rotating rod 206. The driven bevel gear 208 is connected to a chassis 210 via a first threaded rod 209. A connecting plate 212 is connected via a threaded block 211. A groove 216 is formed at the axis of the connecting plate 212. Multiple sets of equally spaced insertion holes 213 are symmetrically formed on the surface of the connecting plate 212 along the groove 216. The bottom of the moving block 214 is slidably connected to the inside of the groove 216. An insertion rod 215 is provided inside the moving block 214. The motor 201 is fixedly installed on the rear left outer wall of the workbench 1. One end of the first rotating rod 202 is fixedly installed on the rotating shaft of the motor 201, and the other end of the first rotating rod 202 is fixedly connected to the surface of the driving pulley 203. The driving pulley 203 and the driven pulley... 205 is connected via belt 204. One end of the second rotating rod 206 is fixedly connected to the outer wall of the driven pulley 205. The circumferential surface of the second rotating rod 206 is rotatably connected to the inner wall of the rear left side of the worktable 1. The other end of the second rotating rod 206 is fixedly connected to the outer wall of the driving bevel gear 207. The driving bevel gear 207 meshes with the driven bevel gear 208. One end of the first threaded rod 209 is fixedly connected to the bottom of the driven bevel gear 208. The other end of the first threaded rod 209 is rotatably connected to the top of the chassis 210. Two sets of chassis 210 are provided. One set of chassis 210 is fixedly installed on the worktable. On the inner wall of the left rear of the workbench 1, and another set of chassis 210 is fixedly installed on the inner wall of the right rear of the workbench 1, the limiting rod 217 is fixedly installed on the inner wall of the right rear of the workbench 1, one end of the limiting rod 217 is fixedly connected to the surface of the right rear of the chassis 210, two sets of threaded blocks 211 are provided, one set of threaded blocks 211 is threadedly connected to the outer wall of the first threaded rod 209, and the other set of threaded blocks 211 is slidably connected to the outer wall of the limiting rod 217, and the corresponding side of the two sets of threaded blocks 211 is fixedly connected to both ends of the connecting plate 212, and the front of the moving block 214 is fixedly installed with a grinding wheel 5.

[0021] On the rear left and right outer walls of the workbench 1, there are grooves that are adapted to the first threaded rod 209 and the limiting rod 217. When the driven bevel gear 208 rotates in the groove adapted to the first threaded rod 209, it will not contact the inside of the groove. On the outer wall of the moving block 214, there is also a socket 213 with the same size as the socket 213. The plug rod 215 passes through the socket 213 on the outer wall of the moving block 214 and the connecting plate 212, thereby fixing the position of the moving block 214. The bottom of the connecting plate 212 is fixedly connected to a slider, which is slidably connected to the inside of the slide groove 216.

[0022] Specifically, through the set adjustment component 2, the operator can start the motor 201, which will drive the drive pulley 203 to rotate. Then, the driven pulley 205 will rotate through the belt 204. At the same time, the drive bevel gear 207 and the driven bevel gear 208 cooperate with each other to drive the threaded block 211 on the first threaded rod 209 to move up and down, thereby driving the connecting plate 212 to move up and down, and appropriately adjusting the height position of the grinding wheel part 5 to meet the processing requirements of the busbar overlapping surface of different height dimensions. In addition, the operator can also manually push the moving block 214 to slide in the slide groove 216, and then fix the position of the moving block 214 through the insertion rod 215 and the insertion hole 213, thereby fixing the lateral position of the grinding wheel part 5. This can ensure that the grinding wheel part 5 is accurately aligned with the processing part and improve the processing accuracy.

[0023] Please see the appendix Figure 1 Appendix Figure 2 and appendix Figure 4 A fixing component 3 is provided above the workbench 1. The fixing component 3 includes a support plate 301 and a handle 302. The support plate 301 is fixedly installed on the top of the workbench 1. A connecting plate 306 is fixedly connected to the surface of the support plate 301. A second threaded rod 303 is fixedly connected to one end of the handle 302. A fixing plate 304 is movably connected to the end of the second threaded rod 303 away from the handle 302. The second threaded rod 303 is threaded to the inner wall of the support plate 301 and the connecting plate 306. A plurality of placement plates 305 are provided on the circumferential surface of the conveyor frame 4.

[0024] The length of the support plate 301 is just in front of the grinding wheel part 5, which can provide additional support for the busbar lap surface. During the processing, when the grinding wheel part 5 grinds the busbar lap surface, a certain cutting force will be generated. At this time, the support plate 301 can effectively reduce the shaking caused by the cutting force on the busbar lap surface, thereby ensuring the stability and accuracy of the processing.

[0025] Specifically, through the fixed component 3, the operator can place the busbar lap surface to be processed on the placement plate 305, then manually hold the handle 302 and rotate it. With the cooperation of the second threaded rod 303, the fixed plate 304 moves inward, thereby achieving the effect of fixing and clamping the busbar lap surface. This ensures that the busbar lap surface remains in the same position throughout the entire processing, effectively preventing displacement of the busbar lap surface during the sanding process, thus ensuring the accuracy and precision of the processing.

[0026] Working principle of this utility model: This utility model is a precision grinding device for the busbar lap surface of a power distribution cabinet. First, the operator starts the motor 201, which drives the first rotating rod 202 to rotate. The rotation of the first rotating rod 202 then drives the driving pulley 203 to rotate, which in turn drives the driven pulley 205 to rotate via the belt 204. The driven pulley 205 then drives the driving bevel gear 207 to rotate via the second rotating rod 206. The driving bevel gear 207 then drives the driven bevel gear 208 to rotate. The rotation of the driven bevel gear 208 then drives the first threaded rod 209 to rotate, thereby allowing the threaded block 211 to move up and down on the outer wall of the first threaded rod 209 and the limiting rod 217, further driving the connection. The plate 212 and the grinding wheel 5 move up and down synchronously to adjust the height of the grinding wheel 5. Then, the operator can manually push the moving block 214 to slide inside the slide groove 216. After sliding to the appropriate position, the horizontal position of the grinding wheel 5 is fixed by using the connection between the insert rod 215 and the insert hole 213. Next, the operator places the busbar overlapping surface on the placement plate 305, then manually holds the handle 302 and rotates it. The handle 302 drives the second threaded rod 303 to rotate, which in turn drives the two sets of fixing plates 304 to move closer to each other to fix and clamp the busbar overlapping surface. Finally, the operator starts the conveyor frame 4 and the grinding wheel 5 at the same time to start working. The conveyor frame 4 can be controlled to start and stop, which is convenient for grinding.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
