[0003] Patent publication number CN115621805A discloses an automotive connector crimping machine with a rotary multi-station fixture, including a workbench, a top die, a die, a cylinder, a cylinder rod, a clamp and a protective cover. When using the above-mentioned automotive connector crimping machine with a rotary multi-station fixture, it is necessary to first place the connector accessory on the top die, then clamp the connector accessory by the clamp, and then extend the cylinder rod by the cylinder to make the die contact with the connector accessory, thereby completing the pressing work. During the pressing process, if the connector accessory If the connector is damaged, then under the pressure of the die, the fragments of the connector accessories will fly away. At this time, the protective cover will block the fragments, so that the fragments will not fly to the operator, thereby protecting the operator. However, because the fragments will be surrounded by the protective cover, the fragments will remain on the workbench, which requires manual cleaning of the workbench later.

DETAILED DESCRIPTION

[0034] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0035] Embodiment 1: A pressing device for a new energy vehicle connector, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, it includes a frame 1, an electric push rod 11 is fixedly connected to the upper rear part of the frame 1, a die 16 is fixedly connected to the lower part of the telescopic rod of the electric push rod 11, a rotating member 13 is rotatably connected to the lower part of the frame 1, four circumferentially distributed fixed seats 19 are fixedly connected to the upper part of the rotating member 13, four-claw chucks 14 are rotatably connected to the fixed seats 19, and a top die 15 is fixedly connected to the upper middle position of the four-claw chucks 14, a driving motor 18 is fixedly connected to the lower part of the frame 1, and the upper part of the output shaft of the driving motor 18 is fixedly connected to the rotating member 13, a protection component is arranged on the die 16, and the protection component is used to prevent fragments from collapsing, and also includes a downward moving member 114, The downward moving member 114 is fixedly connected to the rear part of the die 16, and the first screw rod 112 is rotatably connected to the right side of the lower part of the frame 1, and the second screw rod 113 is fixedly connected to the upper part of the first screw rod 112, and the second screw rod 113 is threadedly connected to the downward moving member 114, and a moving member 115 is threadedly connected to the first screw rod 112, and the moving member 115 is slidably connected to the frame 1, and a rack 111 is fixedly connected to the upper left part of the moving member 115, and the four-claw chuck 14 is fixedly connected to the first gear 110, and the first gear 110 is meshed with the rack 111, and a support frame 116 is fixedly connected to the lower right part of the frame 1, and a storage frame 117 is placed on the upper part of the support frame 116.

[0036] like Figure 1 , Figure 2 and Figure 3 As shown, the protection component includes a protective sleeve 12, which is fixed to the die 16. The protective sleeve 12 can be stretched and deformed, and the protective sleeve 12 has a certain elasticity. The bottom of the protective sleeve 12 is fixed with a magnetic sheet 171, and the upper part of the four-jaw chuck 14 is fixed with a magnetic ring 17. The magnetic ring 17 and the magnetic sheet 171 are attracted to each other through magnetism.

[0037] This device is used for press-fitting and assembling connectors of new energy vehicles. When in use, first, the connector accessories need to be manually placed on the top mold 15. At this time, in order to prevent the subsequent unpressed connector accessories from directly falling into the storage frame 117, there is no need to place the connector accessories on the top mold 15 currently on the far right. Then, the four-claw chuck 14 is debugged so that the four-claw chuck 14 clamps and fixes the connector accessories. Then, the drive motor 18 and the electric push rod 11 are started. Since the programs of the electric push rod 11 and the drive motor 18 have been set in advance, the telescopic rod of the electric push rod 11 will directly extend downward at this time, and the drive motor 18 will not rotate. Driven by the telescopic rod of the electric push rod 11, the die 16, the protective cover 12 and the magnetic suction sheet 171 all move downward. When the magnetic sheet 171 approaches the magnetic ring 17, the magnetic sheet 171 will be adsorbed onto the magnetic ring 17 under the action of magnetism, thereby stretching and deforming the protective cover 12. At this time, the die 16 has not yet contacted the connector accessories. At this time, the connector accessories can be separated from the outside world by the protective cover 12 to prevent the subsequent fragments of the connector accessories from flying and injuring the operator. Then the die 16 will continue to move downward until it contacts the connector accessories. The connector accessories are pressed downward by the die 16 to realize press-fit assembly of the connector. After the pressing is completed, the telescopic rod of the electric push rod 11 will shorten and recover upward. Driven by the telescopic rod of the electric push rod 11, the die 16, the protective cover 12 and the magnetic sheet 171 all move upward and reset. At this time, because the magnetic sheet 171 is stretched The force is greater than the magnetic attraction force, so the magnetic attraction sheet 171 will separate from the magnetic attraction ring 17, and because the protective sleeve 12 itself has a certain elasticity, the protective sleeve 12 will shorten and recover, and then the output shaft of the driving motor 18 will rotate clockwise, so that the rotating member 13, the four-claw chuck 14, the top die 15 and the already pressed connector will rotate clockwise. When the already pressed connector rotates to the far right, a new unpressed connector accessory will rotate to the bottom of the die 16, and then the driving motor 18 will stop rotating, the electric push rod 11 will repeat the previous process, and when the die 16 moves downward, it will also drive the downward moving member 114 to move downward, and when the downward moving member 114 moves downward, it will drive the second screw rod 113 to rotate, and the second screw rod 113 The first screw rod 112 will be driven to rotate. Driven by the first screw rod 112, the moving member 115 will drive the rack 111 to move downward. At this time, the rack 111 will drive the first gear 110 currently on the far right to rotate clockwise. Driven by the first gear 110, the four-claw chuck 14 will rotate clockwise. At this time, the four-claw chuck 14 will be turned upside down. The inverted four-claw chuck 14 will be just above the storage frame 117. Because the four-claw chuck 14 has clamped the pressed connector, the pressed connector will not fall out at this time, and the fragments generated during the pressing process will automatically fall into the storage frame 117, so as to achieve the purpose of automatic cleaning and collection of fragments. Then, as the telescopic rod of the electric push rod 11 is shortened upward and restored,The telescopic rod of the electric push rod 11 drives the downward moving member 114 to move upward and reset, and the second screw rod 113 rotates in the opposite direction under the drive of the downward moving member 114, and the first screw rod 112 also rotates in the opposite direction. At this time, driven by the first screw rod 112, the moving member 115 drives the rack 111 to move upward and reset. At this time, the rack 111 will lead the first gear 110 on the far right to rotate counterclockwise, and the corresponding four-claw chuck 14 will also rotate counterclockwise and reset, and then the output shaft of the drive motor 18 will continue to rotate clockwise, and continue to repeat the steps described above. When the pressed connector rotates to the front side, the operator needs to manually adjust the four-claw chuck 14 so that the four-claw chuck 14 releases the pressed connector, and then removes the pressed connector and places a new connector on the top mold 15. The four-claw chuck 14 clamps and fixes the new connector accessories, so that loading and unloading can be realized. When all the connectors are pressed and removed, the electric push rod 11 and the drive motor 18 are turned off, and then the storage frame 117 is removed. After the fragments in the storage frame 117 are cleaned up, the storage frame 117 is put back on the support frame 116. The telescopic rod of the electric push rod 11 drives the lower moving member 114 to move downward, so that the second screw rod 113 and the first screw rod 112 rotate, so that the first screw rod 112 drives the rack 111 to move. Under the cooperation of the rack 111 and the first gear 110, the four-claw chuck 14 is rotated upside down, so that the fragments generated by the pressed connector can be automatically poured into the storage frame 117, so as to achieve the purpose of automatically cleaning the fragments.

[0038] Embodiment 2: Based on embodiment 1, Figure 6 and Figure 7 As shown, the pressing device for the new energy vehicle connector also includes a cleaning mechanism, which is arranged on the storage frame 117. The cleaning mechanism is used to clean the fragments in the gap between the connector and the four-claw chuck 14. The cleaning mechanism includes a support rod 23, which is rotatably connected to the right part of the frame 1, and a second gear 22 is fixed to the support rod 23. A transmission assembly is arranged between the support rod 23 and the second screw rod 113, and the transmission assembly is used to drive the support rod 23 to rotate. The top of the storage frame 117 is rotatably connected to a rotating member 24, and a plurality of circumferentially distributed notches are arranged on the rotating member 24. The rotating member 24 meshes with the second gear 22 through the notches, and the left and right sides of the rotating member 24 are rotatably connected to brushes 25.

[0039] like Figure 6 As shown, the transmission assembly includes two transmission wheels 2 , one of which is fixedly connected to the top of the second screw rod 113 , and the other is fixedly connected to the top of the support rod 23 , and a transmission belt 21 is wound between the two transmission wheels 2 .

[0040] like Figure 7As shown, the pressing device for the new energy vehicle connector also includes a reset torsion spring 26, and the number of the reset torsion springs 26 is four, two of which are respectively wound between the front and rear sides of the brush 25 on the left and the rotating member 24, and the other two reset torsion springs 26 are respectively wound between the front and rear sides of the brush 25 on the right and the rotating member 24.

[0041] The broken pieces produced by the connector pressing may be stuck in the gap between the connector and the four-claw chuck 14. At this time, it may be difficult to pour out the broken pieces by only relying on the inverted four-claw chuck 14. Therefore, when the second screw rod 113 rotates under the drive of the downward moving member 114, the second screw rod 113 will drive the adjacent transmission wheel 2 to rotate, and this transmission wheel 2 will drive the transmission belt 21 to move. Driven by the transmission belt 21, the transmission wheel 2 on the support rod 23 also rotates, and this transmission wheel 2 will drive the support rod 23 and the second gear 22 to rotate synchronously. Driven by the second gear 22, the rotating member 24 will rotate, thereby causing the brush 25 and the reset torsion spring 26 to rotate accordingly. In this way, when the four-claw chuck 14 is inverted to the top of the storage frame 117, the brush 25 will contact the connector and the four-claw chuck 14, and the connector Under the pressure of the four-claw chuck 14, the brush 25 will rotate and the reset torsion spring 26 will twist. At the same time, under the influence of the force of the reset torsion spring 26, the brush 25 will remain in close contact with the connector and the four-claw chuck 14, which is conducive to cleaning the debris. Because the brush 25 will rotate with the rotating member 24, it can sweep away the debris stuck in the gap between the connector and the four-claw chuck 14. When the four-claw chuck 14 is rotated counterclockwise to reset as described above, the brush 25 is released, and under the action of the reset torsion spring 26, the brush 25 rotates in the opposite direction to reset. When the four-claw chuck 14 is inverted above the storage frame 117, the brush 25 rotates on the four-claw chuck 14 and the connector, so that the debris stuck in the gap between the connector and the four-claw chuck 14 can be swept away, avoiding the debris remaining on the four-claw chuck 14.

[0042] like Figure 8 and Fig. 9 As shown, the pressing device for the new energy vehicle connector also includes a moving mechanism, which is arranged on the four-claw chuck 14. The moving mechanism is used to scrape off the fragments attached to the inner wall of the magnetic ring 17. The moving mechanism includes a sliding frame 32. The number of the sliding frames 32 is four. The four sliding frames 32 are respectively slidably connected to the four four-claw chucks 14. The sliding frames 32 are all slidably connected to the adjacent magnetic rings 17. The four-claw chuck 14 is fixed with a first guide rod 34. The first guide rod 34 is slidably connected to the adjacent sliding frames 32. A reset spring 35 is connected between the first guide rod 34 and the adjacent sliding frames 32. A pulling component is arranged on the four-claw chuck 14, and the pulling component is used to drive the sliding frame 32 to move.

[0043] like Figure 8 and Fig. 9 As shown, the pulling assembly includes a fixed rod 3, the number of the fixed rods 3 is two, the two fixed rods 3 are fixedly connected to the right part of the frame 1, and the two fixed rods 3 are distributed front and back, and the two sides of the four-claw chuck 14 are fixedly connected with connecting parts 31, and the connecting parts 31 are slidably connected with sliding rods 311, and the sliding rods 311 are squeezed and matched with the fixed rods 3, and the sliding rods 311 are squeezed and matched with the rotating parts 13. A connecting rope 33 is connected between the sliding rod 311 and the adjacent sliding frame 32, and the connecting rope 33 is slidably connected to the adjacent magnetic ring 17, and the connecting rope 33 bypasses the adjacent connecting parts 31.

[0044] When the four-claw chuck 14 is inverted on the top of the storage frame 117, some fragments may adhere to the inner wall of the magnetic ring 17. As a result, these fragments do not enter the storage frame 117, but remain on the four-claw chuck 14. In order to solve this problem, when the four-claw chuck 14 on the far right rotates clockwise, driven by the four-claw chuck 14, the corresponding connecting member 31, the sliding rod 311, the connecting rope 33, the sliding frame 32, the first guide rod 34 and the reset spring 35 also rotate clockwise. The connecting member 31 and the sliding rod 311 will gradually approach the fixed rod 3. When the sliding rod 311 contacts the adjacent fixed rod 3, as the connecting member 31 and the sliding rod 311 continue to rotate clockwise, the fixed rod 3 blocks the sliding rod 311 from continuing to rotate, and the connecting member 31 can continue to rotate clockwise, so the sliding rod 311 will slide on the connecting member 31, so that the connecting rope 33 pulls the sliding frame 32 to the side away from the adjacent four-claw chuck 14. At this time, the return spring 35 is compressed and the sliding frame 32 is pulled away from the adjacent four-claw chuck 14. The frame 32 scrapes the broken pieces attached to the inner wall of the magnetic ring 17 into the storage frame 117. When the four-claw chuck 14 on the far right rotates counterclockwise, the corresponding connecting piece 31, sliding rod 311, connecting rope 33, sliding frame 32, first guide rod 34 and reset spring 35 also rotate counterclockwise. The connecting piece 31 and sliding rod 311 will gradually move away from the fixed rod 3. At this time, the connecting rope 33 is loosened. Under the action of the reset spring 35, the sliding frame 32 moves to the side close to the four-claw chuck 14 and resets. When the sliding rod 311 contacts the rotating member 13, the sliding rod 311 will slide on the connecting member 31 under the pressure of the rotating member 13, so that the relative position between the sliding rod 311 and the connecting member 31 is restored, and the sliding rod 311 is squeezed by the fixed rod 3, so that the sliding rod 311 drives the connecting rope 33 to pull the sliding frame 32, so that the sliding frame 32 can scrape the fragments attached to the inner wall of the magnetic ring 17 into the storage frame 117, so as to prevent the fragments from remaining on the magnetic ring 17 and the four-claw chuck 14.

[0045] like Fig.10 and Fig.11As shown, the pressing device for the new energy vehicle connector also includes a preventing mechanism, which is arranged on the lower moving member 114, and is used to shake off the fragments attached to the inner wall of the protective cover 12. The preventing mechanism includes a guide member 4, and the guide member 4 is fixed to the upper right side of the lower moving member 114. A flapping frame 41 is slidably connected to the guide member 4, and a linear spring 42 is connected between the flapping frame 41 and the guide member 4. An extrusion assembly is arranged on the flapping frame 41, and the extrusion assembly is used to drive the flapping frame 41 to perform reciprocating motion.

[0046] like Fig.10 and Fig.11 As shown, the extrusion assembly includes an extrusion piece 43, which is fixed to the rear of the frame 1. A plurality of sawtooth-shaped inclined surfaces are arranged on the right side of the extrusion piece 43. A lever 44 is fixed to the rear of the beating frame 41, and the lever 44 is extruded and matched with the extrusion piece 43.

[0047] The broken pieces produced by the pressed connector parts may also adhere to the inner wall of the protective sleeve 12. In order to clean the protective sleeve 12, the broken pieces on the protective sleeve 12 can be shaken off by knocking. In the initial state, the slapping frame 41 is in contact with the die 16. When the lower moving member 114 moves downward, the lower moving member 114 will drive the guide member 4 to move downward together. Driven by the guide member 4, the slapping frame 41, the linear spring 42 and the lever 44 also move downward. When the lever 44 moves downward to the point where it is in contact with the pressing die 16, the slapping frame 41, the linear spring 42 and the lever 44 move downward. When the serrated inclined surface on the pressing piece 43 contacts, under the pressure of the inclined surface of the extruding piece 43, the lever 44 drives the beating frame 41 to move to the right, the linear spring 42 is compressed, and then as the lever 44 continues to move to the right, the lever 44 will pass over the rightmost end of the inclined surface on the extruding piece 43, and then the lever 44 is released. Under the action of the linear spring 42, the beating frame 41 drives the lever 44 to move to the left and reset. At this time, the beating frame 41 will knock on the die 16, causing the die 16 to vibrate. The vibration will be transmitted to the protective sleeve 12, causing the protective sleeve 12 to vibrate. As the lever 44 continues to move downward, the process is repeated. When the lower moving part 114 moves upward to reset, the slapping frame 41, the linear spring 42 and the lever 44 also move upward. Similarly, the slapping frame 41 will also reciprocate left and right under the joint action of the extrusion member 43 and the linear spring 42. At this time, the slapping frame 41 can knock the die 16 to transmit the vibration to the protective sleeve 12, thereby shaking off the fragments attached to the protective sleeve 12. At this time, the fragments will fall onto the four-claw chuck 14, so that these fragments can be poured into the storage frame 117 together when the four-claw chuck 14 is turned upside down later. The extrusion member 43 squeezes the lever 44, so that the slapping frame 41 can reciprocate left and right with the help of the linear spring 42, thereby knocking the die 16, causing the protective sleeve 12 to vibrate and the fragments attached to the inner wall of the protective sleeve 12 to fall off.

[0048] like Fig.12As shown, the pressing device for the new energy vehicle connector also includes a fixing mechanism, which is arranged on the frame 1, and is used to fix the storage frame 117. The fixing mechanism includes a connecting frame 5, and the connecting frame 5 is fixedly connected to the lower right side of the frame 1. The upper part of the connecting frame 5 is rotatably connected with a two-way screw rod 51, and the upper part of the connecting frame 5 is fixedly connected with a second guide rod 53. The front and rear sides of the two-way screw rod 51 are both threadedly connected with limiting rods 52, and the limiting rods 52 are both slidably connected to the second guide rod 53, and the two limiting rods 52 are respectively located on the front and rear sides of the storage frame 117.

[0049] In order to prevent the storage frame 117 from accidentally falling off the support frame 116 under the impact force of the fragments, the two-way screw rod 51 can be manually rotated so that the two-way screw rod 51 drives the limiting rod 52 to move toward the side in the direction of approaching each other, so that the limiting rod 52 can cooperate with each other to clamp the storage frame 117. At this time, the storage frame 117 is limited, so it can be prevented from falling off. When the storage frame 117 needs to be removed, the two-way screw rod 51 needs to be manually rotated in the opposite direction so that the two-way screw rod 51 drives the limiting rod 52 to move toward the side in the direction of moving away from each other. At this time, the storage frame 117 is released, and then the storage frame 117 can be removed. The storage frame 117 is clamped and limited by the limiting rod 52, which can prevent the storage frame 117 from accidentally falling off the support frame 116.
