[0014] The present invention provides a synchronous riveting device for riveting cables for new energy vehicles. It has the following beneficial effects:

[0015] (1) In the synchronous riveting device for riveting cables for new energy vehicles, the contact surfaces of the clamping block and the limit groove are separated, so that the movement limit imposed by the door-shaped frame on the slide plate is released. By removing the connecting plate from both sides of the second mechanical claw, it is convenient for operators to perform maintenance and repair work, thereby ensuring the safety of riveting. The roller rotates due to the influence of friction, making the cable move more smoothly. The stable contact between the roller and the cable reduces the friction generated by the cable and the second mechanical claw when adjusting the position, and reduces the wear of the cable when moving, making the operation of manually adjusting the cable smoother and more accurate. The cable is then riveted by the first mechanical claw and the second mechanical claw, which improves the work efficiency compared with the manual riveting operation.

[0016] (2) In the synchronous riveting device for cable riveting used in new energy vehicles, the contact plate applies thrust to the slide plate during movement. The slide plate is affected by the thrust and moves away from the carrying box. The kinetic energy generated by the deformation of the No. 3 spring enables the slide plate to quickly move to the designated position for work, effectively improving work efficiency and ease of use. The movement of the rectangular block and the resistance block generate friction, and the speed of movement of the rectangular block is slowed down by the friction. The resistance encountered by the rectangular block after it moves to a safe distance increases, effectively avoiding collision between the rectangular block and the carrying box that affects the stability of the connection, thereby ensuring the stable progress of the riveting work.

[0017] (3) In the synchronous riveting device for cable riveting for new energy vehicles, the rotating plate cannot rotate toward the connecting plate, so that the slide bar is blocked by the rotating plate and cannot be reset. The rotating plate automatically blocks the slide bar, so that when the limit of the slide plate is released by an erroneous operation, the contact plate will not be pushed immediately, thereby improving the safety of the riveting work. The movement of the lifting platform drives the movement of the rotating plate, so that the slide bar does not contact the rotating plate during the movement. The operator actively adjusts the position of the C-shaped plate according to different situations, while maintaining the continuity of the production task, effectively reducing the operating burden of the personnel.

[0028] 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.

The wire clamp itself is elastic and can realize elastic clamping of the cable, so that the wire clamp can adapt to new energy vehicle cables of different sizes, which improves the adaptability of cable riveting. The roller 11 is in stable contact with the circumferential surface of the cable, which effectively reduces the friction between the cable and the second mechanical claw 4 when adjusting the position, and at the same time provides a wire-releasing function for the riveting work, so that the operation of manually adjusting the cable is smoother and more precise.

[0030] A limiting groove is provided on one side of the door-shaped frame 15 close to the grip rod 12, and the block 14 contacts the inner wall of the limiting groove. A sliding groove is provided on one side of the fixed plate 6 close to the grip rod 12. By quickly releasing the limit on the slide plate 7, the connecting plate 8 is removed from both sides of the second mechanical claw 4, which is convenient for operators to carry out maintenance and repair work, thereby ensuring the safety of the riveting work.

[0031] When the present embodiment is working, the cable is manually pulled through the second mechanical claw 4. The cable passes through the connecting plate 8 during the movement, so that the circumferential surface of the cable and the roller 11 are in contact. The movement of the cable applies pressure to the roller 11. The roller 11 is affected by the pressure and moves in the direction away from the cable. The movement of the roller 11 drives the telescopic block 9 to move in the direction away from the cable. The telescopic block 9 squeezes the No. 1 spring 10 during the movement. The No. 1 spring 10 is squeezed and deformed. The deformed No. 1 spring 10 applies a reaction force to the telescopic block 9 under the action of its own elastic force. The telescopic block 9 is affected by the reaction force and pushes the roller 11 to move in the direction of the cable, so that the roller 11 and the circumferential surface of the cable are in stable contact, and the cable continues to be pulled through The first mechanical claw 3, the cable generates friction with the roller 11 during the movement, and the roller 11 rotates under the influence of friction, so that the cable moves more smoothly. After the cable moves to the predetermined position, the first mechanical claw 3 is started, and the first mechanical claw 3 clamps the cable, and the driving mechanism 2 is started. The telescopic end of the driving mechanism 2 moves to drive the first mechanical claw 3 to move downward, and the telescopic end of the driving mechanism 2 moves to drive the second mechanical claw 4 to move downward, so that the clamped cable moves downward and contacts the wire fixing frame at the top of the bracket 1. At the same time, the driving mechanism 2 drives the riveting mechanism 5 to move downward. When the riveting mechanism 5 moves downward, it will contact the cable and the riveting mechanism 5 will squeeze the cable into the inside of the wire fixing clamp, so that the riveting mechanism 5 moves downward. During the movement, the cable is riveted, and the roller 11 is in stable contact with the cable, which reduces the resistance of the cable when adjusting the position, making the manual adjustment of the cable smoother and more precise. When the operator repairs the second mechanical claw 4, the gripping rod 12 is pulled to move away from the fixed plate 6. The gripping rod 12 stretches the second spring 13 during the movement, and the second spring 13 is deformed due to the stretching. At the same time, the movement of the gripping rod 12 drives the block 14 to move away from the fixed plate 6. The surface of the block 14 in contact with the limit groove is separated during the movement, so that the movement limit imposed by the door-shaped frame 15 on the slide plate 7 is released, and the gripping rod 12 is pushed to move in the direction away from the connecting plate 8. The movement of the gripping rod 12 drives the slide plate 7 moves in the direction away from the connecting plate 8, the movement of the slide plate 7 drives the connecting plate 8 to move in the direction of the fixed plate 6, so that the connecting plate 8 is removed from the two sides of the second mechanical claw 4, and when the slide plate 7 moves to the predetermined position, the gripping rod 12 is released, and the deformed No. 2 spring 13 is restored under the action of its own elasticity, and the No. 2 spring 13 is restored to drive the gripping rod 12 to move in the direction of the fixed plate 6, and the movement of the gripping rod 12 drives the clamping block 14 to move in the direction of the fixed plate 6. The clamping block 14 contacts the inner wall of the limit groove during the movement, so that the door-shaped frame 15 imposes a limit on the movement of the slide plate 7, and by removing the connecting plate 8 from the two sides of the second mechanical claw 4, it is convenient for operators to carry out maintenance and repair work, thereby ensuring the safety of riveting.

[0032] See also Figure 1-Figure 9On the basis of the above embodiment, another embodiment of the present invention further includes a speed-up device and a safety device; the speed-up device includes a carrying box 161, a cylindrical rod 162, a third spring 163, a contact plate 164, a rectangular block 165, a slide bar 166, a stop block 167 and a spring 168, the carrying box 161 is fixedly installed inside the fixed plate 6, the cylindrical rod 162 slides through a side of the carrying box 161 close to the slide plate 7, the third spring 163 is arranged between the cylindrical rod 162 and the carrying box 161, and the rectangular block 165 is fixedly installed on the cylindrical rod 166. On the circumferential surface of the rod 162, the slide bar 166 is fixedly installed on the side of the rectangular block 165 away from the carrying box 161, the slide bar 166 slides through the side of the carrying box 161 away from the second mechanical claw 4, the stop block 167 slides through the inner and outer walls of the carrying box 161, and the spring piece 168 is arranged between the stop block 167 and the carrying box 161. The resistance encountered by the rectangular block 165 after moving to a safe distance increases, which effectively avoids the rectangular block 165 from contacting with the carrying box 161 to produce a collision that affects the stability of the connection between the cylindrical rod 162 and the carrying box 161.

[0033] The rectangular block 165 contacts the inner wall of one side of the carrying box 161 close to the contact plate 164, the rectangular block 165 has an arc surface 1 on one side close to the contact plate 164, the block 167 has an inclined surface 1 on one side away from the contact plate 164, the slide rod 166 contacts the inner wall of the slide groove, and the kinetic energy generated by the No. 3 spring 163 enables the contact plate 164 to push the slide plate 7 to quickly move to the designated position for work, thereby effectively improving work efficiency and convenience of use.

[0034] A corrugation 1 is provided on one side of the stop block 167 close to the rectangular block 165 , and the corrugation 1 is in contact with the rectangular block 165 . By providing the corrugation 1 on the stop block 167 , the friction coefficient between the corrugation 1 and the rectangular block 165 is effectively increased, thereby increasing the resistance encountered by the rectangular block 165 when moving.

[0035] The safety device includes a C-shaped plate 171, a lifting platform 172, a No. 4 spring 173, a rotating plate 174, a blocking frame 175, a pull rod 176 and a limit rod 177. The C-shaped plate 171 is slidably installed on the side of the fixed plate 6 away from the second mechanical claw 4, the lifting platform 172 slides through the inner and outer walls of the C-shaped plate 171, the No. 4 spring 173 is arranged between the lifting platform 172 and the C-shaped plate 171, the rotating plate 174 rotates and passes through the side of the lifting platform 172 close to the fixed plate 6, the blocking frame 175 is fixedly installed on the side of the lifting platform 172 close to the rotating plate 174, the pull rod 176 is fixedly installed on the side of the lifting platform 172 away from the rotating plate 174, and the limit rod 177 slides through the top of the C-shaped plate 171, and automatically blocks the sliding bar 166 through the rotating plate 174, so that when the limit of the sliding plate 7 is released by an erroneous operation, the contact plate 164 will not assist in the first time.

[0036] A second slope is provided on one side of the rotating plate 174 close to the blocking frame 175, and the blocking frame 175 contacts a side of the rotating plate 174 close to the second slope. The operator actively adjusts the position of the C-shaped plate 171 to maintain continuity in the production task and effectively reduce the operating burden of the personnel.

[0037] A spiral spring is arranged between the rotating plate 174 and the lifting platform 172, and the limiting rod 177 contacts the inner wall of the circular hole. By arranging the spiral spring, it is ensured that the rotating plate 174 can be reset with the help of the restoring force of the spiral spring after moving, thereby improving the stability for subsequent work.

[0038] When the present embodiment is working, when the slide plate 7 moves in the direction away from the connection plate 8, the slide plate 7 contacts the contact plate 164, and the slide plate 7 continues to move to exert a thrust on the contact plate 164. The contact plate 164 moves toward the carrying box 161 under the influence of the thrust. The movement of the contact plate 164 drives the cylindrical rod 162 to move toward the carrying box 161. The cylindrical rod 162 squeezes the No. 3 spring 163 during the movement. The No. 3 spring 163 is squeezed and deformed. The deformed No. 3 spring 163 stores energy under the action of its own elasticity. At the same time, the movement of the cylindrical rod 162 drives the rectangular block 165 to move toward the carrying box 161. The rectangular block 165 moves The slide bar 166 is driven to move in the direction away from the contact plate 164. At the same time, the rectangular block 165 is separated from the surface in contact with the corrugation 1 during the movement. The pressure exerted by the rectangular block 165 on the stop block 167 is gradually reduced, so that the deformed spring piece 168 is restored under the action of its own elasticity. The spring piece 168 restores and drives the stop block 167 to move in the direction of the cylindrical rod 162. When the operator needs to use the auxiliary function to release the limit of the slide plate 7, the pressure exerted by the slide plate 7 on the contact plate 164 is gradually reduced, so that the deformed No. 3 spring 163 is restored and drives the cylindrical rod 162 to move. The movement of the cylindrical rod 162 drives the contact plate 164 away from the carrying box. The contact plate 164 applies a thrust to the slide plate 7 during the movement. The slide plate 7 is affected by the thrust and moves in the direction away from the carrying box 161. The kinetic energy generated by the No. 3 spring 163 enables the slide plate 7 to quickly move to the designated position for work, which effectively improves the work efficiency and the convenience of use. When the cylindrical rod 162 moves in the direction away from the carrying box 161, the movement of the cylindrical rod 162 drives the rectangular block 165 to move in the direction of the contact plate 164. The arc surface 1 of the rectangular block 165 contacts the inclined surface 1 during the movement. The arc surface 1 continues to move and applies pressure to the inclined surface 1. The block 167 is affected by the pressure and moves away from the cylindrical rod 162. The column 162 moves in the direction of the inclined surface 1, and the surface in contact with the arc surface 1 is separated during the movement. At the same time, the block 167 squeezes the spring sheet 168 during the movement, and the spring sheet 168 is squeezed and deformed. The deformed spring sheet 168 applies a thrust to the block 167 under the action of its own elasticity. The corrugation 1 of the block 167 is in close contact with the rectangular block 165 under the action of the thrust, so that the rectangular block 165 moves and generates friction with the block 167. The speed of the rectangular block 165 is slowed down by the friction, and the resistance of the rectangular block 165 increases after the rectangular block 165 moves to a safe distance, which effectively avoids the contact and collision between the rectangular block 165 and the carrying box 161.

[0039] When the slide bar 166 moves toward the carrying box 161, the slide bar 166 contacts the second inclined surface, and the slide bar 166 continues to move to apply a thrust to the second inclined surface. The rotating plate 174 is affected by the thrust and rotates in the direction away from the slide bar 166. The rotating plate 174 stretches the spiral spring during the rotation process, and the spiral spring is deformed by the stretching. The slide bar 166 continues to move and separates from the surface in contact with the second inclined surface. The deformed spiral spring recovers under the action of its own elasticity. The recovery of the spiral spring drives the rotating plate 174 to return to its original position, and the slide bar 166 returns to its original position. When the pull rod 176 is manually pushed downward, the pull rod 176 moves to drive the lifting platform 172 downward, and the lifting platform 172 moves to drive the rotating plate 174 downward. During the movement, the rotating plate 174 and the sliding bar 166 are in contact. The contact surface of rod 166 is separated, so that the blocking imposed by rotating plate 174 on the reset of sliding rod 166 is released, and the sliding rod 166 is automatically blocked by rotating plate 174, so that when the limit imposed on sliding plate 7 is released by erroneous operation, contact plate 164 will not be pushed at the first time. During continuous production, the operator actively pulls the limit rod 177 upward, and the contact surface of limit rod 177 and the circular hole are separated during the movement, so that the limit imposed by fixed plate 6 on the movement of C-shaped plate 171 is released, and pull rod 176 is pulled away from fixed plate 6. The plate moves in the direction of 6, the pull rod 176 moves to drive the lifting platform 172 to move away from the fixed plate 6, the lifting platform 172 moves to drive the C-shaped plate 171 to move away from the fixed plate 6, and at the same time, the lifting platform 172 moves to drive the rotating plate 174 to move away from the fixed plate 6, so that the sliding rod 166 does not contact the rotating plate 174 during the movement. The operator actively adjusts the position of the C-shaped plate 171 according to different situations to maintain the continuity of the production task and effectively reduce the operating burden of the personnel.
