[0002] A grounding ring is a component used in electrical and electronic equipment. Its primary purpose is to provide a low-impedance path to safely conduct static electricity, lightning strikes, or fault currents to the ground. Effective grounding can significantly improve system safety, stability, and performance. Highly conductive fiber grounding rings combine the unique properties of highly conductive fiber materials and have excellent conductivity. These grounding rings are typically used in applications requiring efficient and reliable grounding solutions.

[0003] Existing high-conductivity fiber grounding rings have many advantages over ordinary grounding rings, but they still have shortcomings: most of the existing high-conductivity fiber grounding rings are split structures and are formed by multi-layer press-assembly, with poor precision. Moreover, during long-term use, due to factors such as thermal expansion and contraction, mechanical vibration, etc., the layers of the high-conductivity fiber grounding rings may separate or have poor contact, resulting in a decrease in conductive performance.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0030] See also Figure 1 The present invention provides a technical solution: a highly conductive fiber grounding ring for an automotive motor, comprising a grounding body 1, an inner ring hole 11 extending through the middle of the upper end surface of the grounding body 1, circular holes 12 perpendicular to the ring body axis uniformly opened on the inner ring surface of the grounding body 1 along its circumferential direction, the circular holes 12 extending through to the outer ring surface, recessed grooves 13 opened at positions corresponding to the upper end surface of the grounding body 1 and the circular holes 12, a through hole 14 symmetrically opened on the upper end surface of the grounding body 1 along its diameter line, and the through hole 14 and the circular hole 12 are both provided with inverted inner fillets at their openings.

[0031] See also Figure 1 、 Figure 2 、 Figure 6In this embodiment, in which: in the process of opening the inner ring hole 11, a special processing device is required, which includes a placing plate 2, a supporting assembly 3, a cutting mechanism 4 and a fixing mechanism 5. The upper end surface of the placing plate 2 is installed with the supporting assembly 3, and the middle part of the supporting assembly 3 is installed with the cutting mechanism 4; the cutting mechanism 4 includes an L-shaped plate 41 symmetrically installed on the supporting assembly 3, and the lower end surfaces of the horizontal sections of the two L-shaped plates 41 are jointly installed with a lifting assembly 42, and the opposite surfaces of the horizontal sections of the two L-shaped plates 41 are jointly installed with a ring cutting assembly 43, and a pushing assembly 44 for pushing out the cutting waste is provided in the ring cutting assembly 43; the fixing mechanism 5 includes an extrusion clamping assembly 51 symmetrically arranged below the supporting assembly 3 and a pressing assembly 52 symmetrically installed on the lifting assembly 42 front and back.

[0032] See also Figure 2 The support assembly 3 includes an L-shaped support plate 31 symmetrically installed on the placement plate 2, and a circular plate 32 is installed between the L-shaped support plates 31. A clearance hole 21 coaxial with the circular plate 32 is opened in the middle of the placement plate 2. When working, the material blank to be cut is placed at the clearance hole 21 on the placement plate 2 below the circular plate 32.

[0033] See also Figure 1 、 Figure 8 The lifting assembly 42 includes a cylinder 421 installed on the lower end surface of the horizontal section of the L-shaped plate 41, and the vertical section of the L-shaped plate 41 is installed on the horizontal section of the L-shaped support plate 31. The telescopic ends of the cylinder 421 are installed with lifting blocks 422. The cross-section of the lifting block 422 is a horizontal U-shaped structure. The front and rear ends of the lifting block 422 are jointly installed with arc plates 423, and the two arc plates 423 are symmetrical front and back; rectangular through holes are opened on the horizontal sections of the L-shaped support plate 31, and extrusion blocks 35 are arranged in the rectangular through holes. The upper part of the extrusion block 35 is a vertical structure and is slidably connected to the rectangular through holes. The lower part of the extrusion block 35 is an inclined structure that gradually tilts toward the side of the vertical section of the L-shaped support plate 31. The extrusion block 35 cooperates with the extrusion clamping assembly 51.

[0034] See also Figure 1The cam 512 is pressed against the top of the plate 512 and the bottom of the plate 512 is pressed against the top of the plate 512. The cam 512 is pressed against the top of the plate 512 and the bottom of the plate 512 is pressed against the top of the plate 512.

[0035] See also Figure 1 、 Figure 7 The downward pressing assembly 52 includes a bending rod 521. Multiple bending rods 521 are evenly mounted along the arc direction of the lower end of the front-to-back symmetrical curved plate 423. A curved pressure plate 522 is mounted on the lower end of each of the bending rods 521. The vertical sections of the bending rods 521 are elastically retractable, and the curved pressure plate 522 has an L-shaped cross-section. During operation, the cylinder 421 drives the curved plate 423 downward synchronously via the lifting block 422. The bending rods and curved pressure plate 522 on the curved plate 423 compress and secure the front and rear sides of the blank. When the annular cutter 435 moves into contact with the blank, the extrusion block 35 clamps and secures the left and right outer walls of the blank, while the curved pressure plate 522 compresses and secures the front and rear positions of the blank. This multi-directional fixed position of the blank eliminates the need for manual or mechanical fixation, reducing processing costs while ensuring the stability of the blank.

[0036] See also Figure 4 、 Figure 5 、 Figure 6The cam 432 is a kind of cam which is fixed to the workpiece by the cam 434 and the cam 436 is a kind of cam which is fixed to the workpiece by the cam 436. The position of the limiting ring plate 436 close to the outer wall is slidably connected to the inner part of the lifting block 422. When working, the cylinder 421 drives the limiting ring plate 436 to move downward through the lifting block 422. The limiting ring plate 436 moves downward to extend the lifting cylinder 434. The annular cutter 435 on the fixed section of the lifting cylinder 434 also moves gradually toward the blank at the same time until the annular cutter 435 gradually moves to contact with the top of the blank. Then, the rotating motor 433 is started, and the rotating motor 433 drives the lifting cylinder 434 to extend. The circular cutter 435 is driven to rotate and perform circular cutting on the middle part of the blank. The cylinder 421 cooperates with the rotary motor 433 to gradually move downward while performing the rotation cutting. When the lifting cylinder 434 rotates, the limiting ring plate 436 also rotates. Due to the limiting cooperation between the limiting ring plate 436 and the lifting plate, and the cooperation between the limiting ring plate 436 and the multiple spring telescopic rods, the limiting ring plate 436 is limited in rotation, thereby ensuring the stability of the circular cutter 435 during the rotation cutting.

[0037] See also Figure 3 、 Figure 4 Elastic telescopic rods 33 are evenly mounted along the outer wall of the upper end of the circular ring plate 32. Ball bearings 34 are rotatably mounted on the telescopic ends of the elastic telescopic rods 33. An annular guide groove 437 is formed on the lower end surface of the limiting ring plate 436. The balls 34 on the elastic telescopic rods 33 engage with the annular guide groove 437. During operation, when the annular cutter 435 moves to contact the blank, the limiting ring plate 436 also moves down to a designated position. The annular guide groove 437 on the limiting ring plate 436 comes into contact with the balls 34 on the elastic telescopic rods 33. Thus, the cooperation between the multiple spring telescopic rods and the annular guide groove 437 improves the stability of the annular cutter 435 on the limiting ring plate 436 during operation, ensuring the circular cutting effect.

[0038] See also Figure 6The pushing assembly 44 includes an extrusion spring 441, which is mounted on the inner top end of the fixed section of the lifting cylinder 434, and the other end of the extrusion spring 441 is connected to a shift circular plate 442, and a T-shaped push block 443 is mounted on the lower end of the shift circular plate 442. The horizontal section of the T-shaped push block 443 is arranged in the annular cutter 435, and the outer wall of the vertical section of the T-shaped push block 443 slides up and down and is arranged at the center position of the annular cutter 435; the outer wall of the fixed section of the lifting cylinder 434 is evenly provided with long holes 438, and the lower end of the circular plate 32 is provided with an annular slide groove 439. A limiting rod 4310 is slidably installed in the annular slide groove 439 at a position corresponding to the long hole 438. The end of the limiting rod 4310 close to the T-shaped push block 443 passes through the corresponding long hole 438 and extends to the bottom of the shift circular plate 442, and the limiting rod 4310 slides vertically in the long hole 438. During operation, when the lifting cylinder 434 is extended to drive the annular cutter 435 to move downward, the position of the long hole 438 is moved downward by the extension of the lifting cylinder 434. Due to the multiple limit rods 4310 extending below the shifting circular plate 442, the positions of the shifting circular plate 442 and the T-shaped push block 443 do not change during the downward movement of the lifting section of the lifting cylinder 434, so that the T-shaped push block 443 and the annular cutter 435 slide relative to each other, causing the bottom of the T-shaped push block 443 to gradually move downward. The T-shaped push block 443 automatically slides upwards when the circular cutter 435 cuts while the circular cutter 435 is cutting, which will not affect the normal circular cutting effect. Moreover, after the circular cutting is completed, the circular cutter 435 moves upwards, and the elastic force of the extrusion spring 441 exerts a certain supporting force on the T-shaped push block 443, so that the T-shaped push block 443 will not move upward synchronously with the circular cutter 435, thereby realizing the pushing out of the waste inside the circular cutter 435, which is convenient for the circular cutting work again.

[0039] During specific operation, the blank to be cut is placed at the position of the makeshift hole 21 on the placement plate 2 below the circular ring plate 32, and the cylinder 421 extends to drive the lifting block 422 to move downward. The lifting block 422 moves downward and simultaneously drives the extrusion block 35, the limiting ring plate 436 and the arc plate 423 to move downward synchronously. When the lifting block 422 drives the extrusion block 35 to slide down in the rectangular through hole, due to the structure of the extrusion block 35, the lifting block 422 drives the bottom extrusion block 35 to slide downward in the rectangular through hole during the downward movement. The inclined surface structure of the lower part of the extrusion block 35 contacts the top of the slide plate 512 when it moves downward. The downward pressure of the inclined structure of the lifting block 422 causes the slide plate 512 to move in the sliding groove 511 toward the blank, thereby driving the rubber clamping block 513 to clamp the left and right outer walls of the blank. The lifting block 422 drives the limiting ring plate 436 and the arc plate 423 to move downward synchronously, and the bending rod and the arc pressure plate 522 on the arc plate 423 press and limit the front and rear side positions of the material blank, the extrusion block 35 clamps and fixes the left and right outer walls of the material blank, and the arc pressure plate 522 limits, presses and fixes the front and rear positions of the material blank, and limits and fixes the material blank in multiple directions, thereby ensuring the stability of the material blank; when the annular cutter 435 moves to contact the material blank, the limiting ring plate 436 also moves down to the specified position, and the annular guide groove 437 on the limiting ring plate 436 contacts the ball 34 on the elastic telescopic rod 33, thereby improving the stability of the annular cutter 435 on the limiting ring plate 436 during operation through the cooperation of multiple spring telescopic rods and the annular guide groove 437, thereby ensuring the circular cutting effect.

[0040] The rotary motor 433 is then started, and the rotary motor 433 drives the annular cutter 435 to rotate through the lifting cylinder 434 to perform annular cutting on the middle position of the blank. The cylinder 421 cooperates with the rotary motor 433 to gradually move downward while performing the rotary cutting. When the lifting cylinder 434 rotates, the limit ring plate 436 also rotates. Due to the limited cooperation between the limit ring plate 436 and the lifting plate, and the cooperation between the limit ring plate 436 and the multiple spring telescopic rods, the limit ring plate 436 is limited in rotation, thereby ensuring the stability of the annular cutter 435 during the rotary cutting. As the cutting depth increases, the pressing force of the arc pressure plate 522 and the limit ring plate 436 also increases, which greatly improves the stability of the annular cutting. In the process of the lifting cylinder 434 extending and driving the annular cutter 435 to move downward, the extension of the lifting cylinder 434 causes the limit ring plate 436 to rotate. The position of the long hole 438 is moved downward. Due to the multiple limit rods 4310 extended below the gear circular plate 442, the positions of the gear circular plate 442 and the T-shaped push block 443 do not change during the downward movement of the lifting section of the lifting cylinder 434, so that the T-shaped push block 443 and the annular cutter 435 slide relative to each other, so that the bottom of the T-shaped push block 443 gradually approaches the inner top wall of the annular cutter 435. While the annular cutter 435 is cutting, the T-shaped push block 443 automatically slides upward, which will not affect the normal annular cutting effect. After the annular cutting is completed, the annular cutter 435 moves upward, and under the action of the elastic force of the extrusion spring 441, a certain supporting force is exerted on the T-shaped push block 443, so that the T-shaped push block 443 will not move up synchronously with the annular cutter 435, thereby realizing the pushing out of the waste inside the annular cutter 435, which is convenient for the annular cutting work again.
