Description

Technical Field

[0001] The invention relates to the technical field of terminal crimping, and in particular to a high-power terminal crimping device. Background Art

[0002] The process of terminal crimping is to apply pressure between the wire and the terminal through special crimping pliers or automatic or semi-automatic crimping machines to shape and tightly connect them. When crimping cables and terminals, existing terminal machines usually need to first put the sealing ring on the fixed position of the terminal, then transport the terminal to the terminal machine, and then manually insert the cable end into the terminal. The terminal machine is started, and the mold inside the terminal machine presses the terminal to fix the terminal and the cable. High-power terminal blocks are one type of terminal blocks, and the new type of terminal blocks involved is a high-current terminal block for connecting cables.

[0003] For example, the Chinese patent with the authorization announcement number CN112054364B and the name of a wire harness terminal crimping device, first select a crimping seat of appropriate size according to the thickness of the wire harness, for example, select crimping seat No. 1, then rotate the crimping seat No. 1 to the bottom of the two connecting rods through the turntable, then place the wire harness on the inclined surfaces of the adjacent ends of the two connecting rods, press the wire harness so that the wire harness falls into the semicircular groove on the crimping seat No. 1, then press the two pressure rods to move the No. 1 extrusion plate and the No. 2 extrusion plate toward the No. 1 crimping seat, at this time, the No. 1 extrusion plate and the No. 2 extrusion plate respectively squeeze the inclined surfaces of the connecting rods at the corresponding positions, and the two connecting rods move in the direction away from the No. 1 crimping seat, and the two compression springs are in a compressed state. When the wire harness is squeezed between the No. 1 extrusion plate and the No. 2 extrusion plate, move the pressure rods to both sides to make the No. 1 extrusion plate and the No. 2 extrusion plate crimp the wire harness terminals, and the working principles of the No. 2 crimping seat and the No. 3 crimping seat are the same as above.

[0004] With respect to the above-mentioned related technologies, only the size of the crimping seat is changed for wire harnesses of different thicknesses, while the size of the extrusion plate remains unchanged. Because the first extrusion plate and the second extrusion plate are in direct contact with the wire harness when crimping the wire harness terminal, the first extrusion plate and the second extrusion plate are not adjusted in size accordingly for wire harnesses of different thicknesses, making it difficult to process wire harness terminals of different thicknesses. Summary of the invention

[0005] In view of this, the present invention provides a high-power terminal crimping device, which aims to solve the problem that the first extrusion plate and the second extrusion plate are not adjusted accordingly for wire harnesses of different thicknesses and sizes, making it difficult to process wire harness terminals of different thicknesses and sizes.

[0007] By adopting the above technical solution, the distance that the crimping block moves close to the central axis of the support wheel is adjusted by controlling the moving distance of the transmission rack, so that wire harness terminals of different thicknesses can be crimped, which increases the variety of wire harness terminals that can be processed by the crimping block. In addition, the stamping part processes a groove on the surface of the terminal. On the one hand, the bottom surface of the groove can strengthen the degree of compression of the terminal on the wire harness. On the other hand, the bottom surface and side surface of the groove form reinforcing ribs, which increase the strength of the terminal, reduce the probability of the terminal being bent, and improve the quality of the wire harness terminal.

[0010] By adopting the above technical solution, the copper wire abuts against the tapered inner side of the elastic ring, and the elastic ring squeezes the copper wire and gradually bends it toward the central axis of the wire, so that the outer diameter of the cylinder composed of all the copper wires becomes smaller, which is beneficial for the copper wire in the wire to penetrate into the terminal, thereby improving the crimping efficiency of the wire terminal.

[0011] Optionally, a second limiting rod is fixedly connected to the upper surface of the bracket, the second limiting rod is arranged at an end of the sliding plate away from the crimping block, and a third limiting rod capable of abutting against the second limiting rod is fixedly connected to the outer side surface of the limiting ring.

The clamp on the support plate drives the wire to move until the groove on the surface of the wire cooperates with the sealing ring, so that the sealing ring is stuck in the groove, and the wire drives the sealing ring to detach from the support rod, thereby installing the sealing ring on the wire.

[0016] Optionally, a clamp for fastening the wires is detachably connected to the upper surface of the support plate.

[0017] Optionally, the bracket is fixedly connected to a loading block, and the loading block is arranged at the end of the rotating wheel away from the support ring.

In addition, the stamping part processes a groove on the surface of the terminal. On the one hand, the bottom surface of the groove can strengthen the degree of compression of the terminal on the wire harness. On the other hand, the bottom surface and side surface of the groove form reinforcing ribs, which increases the strength of the terminal, reduces the probability of the terminal being bent, and improves the quality of the wire harness terminal.

[0021] 2. The copper wire abuts against the tapered inner side of the elastic ring. The elastic ring squeezes the copper wire and gradually bends it toward the central axis of the wire, making the outer diameter of the cylinder composed of all the copper wires smaller, which is conducive to the copper wire in the wire to penetrate into the terminal, thereby improving the crimping efficiency of the wire terminal.

Figure 1-Figure 8 , the technical scheme of the embodiment of the present invention is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0032] This embodiment provides a high-power terminal crimping device, referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 A high-power terminal crimping device includes a bracket 1, a support shell 11, a rotating wheel 12, a first linear driver 13, a transmission rack 14, a transmission rod 15, a crimping block 16, a support wheel 17 and a guide rod 18. The bracket 1 is erected on a horizontal plane, the support shell 11 is fixedly connected to the upper surface of the bracket 1, the rotating wheel 12 is rotatably connected to the inside of the support shell 11, and the arc-shaped side surface of the rotating wheel 12 is provided with a plurality of tooth grooves 121 along the circumferential direction. The first linear driver 13 is vertically fixedly connected to the bracket 1, the transmission rack 14 is fixedly connected to the driving shaft of the first linear driver 13, and the transmission rack 14 can mesh with the tooth grooves 121.

[0033] Reference Figure 3 and Figure 4 The bottom surface of the rotating wheel 12 is provided with a plurality of guide slots 122 along the circumferential direction, and the length direction of each guide slot 122 is gradually arranged close to the central axis of the rotating wheel 12. The transmission rod 15 is slidably arranged in the guide slot 122, and the crimping block 16 is fixedly connected to the transmission rod 15, and the crimping block 16 is slidably connected to the rotating wheel 12 along the radial direction. The side of the crimping block 16 close to the central axis of the rotating wheel 12 is a crimping surface 162 that can abut against the terminal 2, and the crimping surface 162 is fixedly connected with a stamping portion 161, and the stamping portion 161 protrudes from the crimping surface 162, and can stamp a groove on the surface of the terminal 2.

[0034] Reference Figure 3 and Figure 4 The support wheel 17 is fixedly connected to the inside of the support shell 11, and the support wheel 17 is coaxially rotatably connected to the rotating wheel 12. The arcuate side of the support wheel 17 is radially slidably connected with a guide rod 18. A plurality of guide rods 18 are provided and distributed along the circumference of the support wheel 17. The guide rod 18 is fixedly connected to the crimping block 16.

[0035] When crimping the terminal 2, the operator first places the terminal 2 between the plurality of crimping blocks 16, and the first linear actuator 13 is started to drive the transmission rack 14 to move downward, and the transmission rack 14 drives the rotating wheel 12 to rotate counterclockwise through the tooth groove 121 (refer to Figure 4 ), the guide slot 122 rotates synchronously with the rotating wheel 12, the guide slot 122 drives the transmission rod 15 to move close to the central axis of the rotating wheel 12, the crimping block 16 moves along the axial direction of the guide rod 18 with the transmission rod 15, and the stamping part 161 moves synchronously with the crimping block 16 to abut against the terminal 2 and fix the terminal 2. The operator inserts the wire 21 into the terminal 2, the first linear drive 13 drives the transmission rack 14 to continue to move downward, and the stamping part 161 moves toward the inside of the terminal 2, thereby pressing a groove on the surface of the terminal 2.

[0036] By controlling the moving distance of the transmission rack 14, the distance that the crimping surface 162 moves close to the central axis of the support wheel 17 is adjusted, so that the wiring harness terminals 2 of different thicknesses can be crimped, and the types of thicknesses and specifications of the wiring harness terminals 2 that can be processed by the crimping block 16 are increased. In addition, the stamping portion 161 processes a groove on the surface of the terminal 2. On the one hand, the bottom surface of the groove can strengthen the degree of compression of the terminal 2 on the wiring harness. On the other hand, the bottom surface and side surface of the groove form reinforcing ribs, which increase the strength of the terminal 2, reduce the probability of the terminal 2 being bent, and improve the quality of the wiring harness terminal 2.

[0037] Reference Figure 5 , Figure 6 and Figure 7A first feeding mechanism is provided on one side of the rotating wheel 12, and the first feeding mechanism is used to convey the wire harness to the rotating wheel 12. The first feeding mechanism includes a sliding plate 3, a first rotating source 41, a first screw 42, a supporting ring 31, a first limiting rod 34, a pressing block 35 and a first reset spring 36. The sliding plate 3 is slidably connected to the bracket 1, the first rotating source 41 is fixedly connected to the bracket 1, and the first screw 42 is fixedly connected to the driving shaft of the first rotating source 41. The first rotating source 41, the first screw 42 and the sliding plate 3 form a first screw slider mechanism 4, and the first rotating source 41 is started to drive the sliding plate 3 to move through the first screw 42.

[0038] Reference Figure 5 , Figure 6 and Figure 7 The support ring 31 is fixedly connected to the upper surface of the sliding plate 3, and the support ring 31 allows the wire harness to pass through. The limiting ring 32 is slidably sleeved on the outer side of the support ring 31. The outer side of the limiting ring 32 is a conical surface. The outer side of the limiting ring 32 is composed of a first conical surface 322 and a second conical surface 323. The side of the limiting ring 32 close to one end of the rotating wheel 12 protrudes from the side of the support ring 31. The support ring 31 and the limiting ring 32 are both slidably connected to the first sliding rod 33. The first sliding rod 33 can move along the radial direction of the support ring 31 and the limiting ring 32, and the first sliding rod 33 can move along the axial direction of the limiting ring 32. The first limiting rod 34 is fixedly connected to one end of the first sliding rod 33 extending out of the limiting ring 32, and the first limiting rod 34 can abut against the outer side of the limiting ring 32.

[0039] Reference Figure 5 , Figure 6 and Figure 7 A third return spring 391 is fixedly connected between the limit ring 32 and the support ring 31. The third return spring 391 (no mark in the figure) is used to pull the limit ring 32 so that the first limit rod 34 is located between the first conical surface 322 and the second conical surface 323. The pressing block 35 is fixedly connected to the end of the first slide bar 33 away from the first limit rod 34. The pressing block 35 is arranged inside the support ring 31. The inner side surface of the pressing block 35 is a conical surface. The inner side surface of the pressing block 35 can abut against the copper wire 22 in the wire 21. The first return spring 36 is sleeved on the outer side surface of the first slide bar 33. The first return spring 36 is arranged between the pressing block 35 and the support ring 31. The first return spring 36 can pull the first limit rod 34 to be located between the first conical surface 322 and the second conical surface 323 through the first slide bar 33. At this time, the copper wire 22 in the wire 21 cannot pass through the pressing block 35. Four first slide bars 33, first limit bars 34, pressure blocks 35 and first return springs 36 are provided and arranged along the circumference of the support ring 31. The inner side surfaces of all pressure blocks 35 are fixedly connected with an elastic ring 37, and the inner side surface of the elastic ring 37 is a conical surface.

[0040] When the wire 21 passes through the support ring 31, the first rotation source 41 moves the sliding plate 3 close to the rotating wheel 12 through the first screw rod 42, and the limit ring 32 moves synchronously with the sliding plate 3 until the limit ring 32 abuts against the outer side surface of the support shell 11, and the support shell 11 limits the movement of the limit ring 32. Since the side surface of the limit ring 32 close to the rotating wheel 12 protrudes from the side surface of the support ring 31, the support ring 31 continues to move synchronously with the sliding plate 3 until the side surface of the limit ring 32 and the support ring 31 close to the crimping block 16 are flush. The limiting ring 32 moves relative to the support ring 31. Since the first slide bar 33 cannot move along the axial direction of the support ring 31, the support ring 31 drives the first slide bar 33 to move, so that the first limiting rod 34 abuts against the first conical surface 322. The first conical surface 322 drives the pressing block 35 to move away from the central axis of the support ring 31 through the first limiting rod 34 and the first slide bar 33. The pressing block 35 expands the inner diameter of the elastic ring 37 so that the copper wire 22 can pass through the elastic ring 37. The copper wire 22 abuts against the tapered inner side surface of the elastic ring 37, and the elastic ring 37 squeezes the copper wire 22 and gradually bends toward the central axis of the wire 21, so that the outer diameter of the cylinder composed of all the copper wires 22 becomes smaller, which is conducive to the copper wire 22 in the wire 21 to penetrate the terminal 2, and improves the crimping efficiency of the wire 21 and the terminal 2.

[0041] Reference Figure 1 , Figure 6 and Figure 7 A second limiting rod 19 is fixedly connected to the upper surface of the bracket 1, and the second limiting rod 19 is arranged at one end of the sliding plate 3 away from the crimping block 16. The outer side of the limiting ring 32 is fixedly connected to a third limiting rod 321 that can abut against the second limiting rod 19. When the terminal 2 is crimped, the first rotation source 41 moves the sliding plate 3 away from the rotating wheel 12 through the first screw rod 42, and the limit ring 32 and the third limit rod 321 move synchronously with the sliding plate 3 until the third limit rod 321 abuts against the second limit rod 19, and the second limit rod 19 limits the movement of the limit ring 32 through the third limit rod 321, and the first screw slider mechanism 4 continues to drive the sliding plate 3 to move, so that the support ring 31 moves away from the crimping block 16 relative to the limit ring 32, and the support ring 31 drives the first slide bar 33 to move, and the first limit rod 34 moves synchronously with the first slide bar 33, so that the first limit rod 34 abuts against the second conical surface 323, and the second conical surface 323 drives the crimping surface 162 to move away from the central axis of the support ring 31 through the first limit rod 34 and the first slide bar 33. Since the diameter of the terminal 2 is larger than the diameter of the wire 21 , the crimping surface 162 moves away from the central axis of the support ring 31 , so that the crimped terminal 2 can be taken out of the crimping block 16 .

[0042] Reference Figure 1 , Figure 6 and Figure 7, the outer side of the terminal 2 is provided with a groove along the circumferential direction, and the wire 21 is provided with an elastic sealing ring through the groove. When the terminal 2 is assembled with other shells, the sealing ring is located between the terminal 2 and the shell to seal the wire 21. The support ring 31 is hinged with four struts 38 along the circumferential direction, and the sealing ring is sleeved on the outer side of the strut 38. The end of the strut 38 close to the support ring 31 is fixedly connected with a transmission cam 381, and a reset torsion spring 39 is fixedly connected between the transmission cam 381 and the support ring 31. The outer side of the support ring 31 is slidably sleeved with a fastening ring 5, which is arranged at the end of the limit ring 32 away from the crimping block 16, and the inner side of the fastening ring 5 is fixedly connected with a fourth limit rod 51 that can abut against the transmission cam 381, and a second reset spring 52 is connected between the support ring 31 and the fastening ring 5. The bracket 1 is connected with a support plate 53 and a second screw slider mechanism 6 for driving the support plate 53 to move, and a telescopic rod 54 is fixedly connected between the support plate 53 and the fastening ring 5.

[0043] Before the wire 21 passes through the support ring 31, the operator pushes the fastening ring 5 away from the side of the limiting ring 32, the second return spring 52 is compressed, the fourth limit rod 51 moves synchronously with the fastening ring 5 to disengage from the transmission cam 381, and the return torsion spring 39 drives the transmission cam 381 to rotate counterclockwise (refer to Figure 7 ), so that the end of the support rod 38 away from the transmission rotates toward the central axis of the support ring 31, and the operator sets the sealing ring on the outer surface of the support rod 38. Then the operator releases the fastening ring 5, and the second return spring 52 pushes the fastening ring 5 to move close to the limit ring 32, and the fourth limit rod 51 pushes the support rod 38 to rotate clockwise through the transmission cam 381 (refer to Figure 7 ), so that the support rod 38 expands the sealing ring, thereby allowing the wire 21 to pass through the sealing ring.

[0044] After the terminal 2 is crimped, there is a smooth conical transition between the wire 21 and the terminal 2. The second screw slider mechanism 6 drives the fastening ring 5 to move away from the limit ring 32 through the support plate 53 and the telescopic rod 54, so that the end of the support rod 38 away from the transmission rotates toward the central axis of the support ring 31. The four support rods 38 tighten the sealing ring into a rectangle, and the rectangular side of the support ring 31 abuts against the outer side of the wire 21. The operator drives the wire 21 away from the support wheel 17, and the terminal 2 moves synchronously with the wire 21 until the groove on the surface of the terminal 2 cooperates with the sealing ring, so that the sealing ring is stuck in the groove, and the terminal 2 drives the sealing ring to disengage from the support rod 38, thereby installing the sealing ring on the terminal 2.

[0045] The second screw slider mechanism 6 includes a second rotation source 61 and a second screw 62 . The second rotation source 61 is fixedly connected to the bracket 1 . The second screw 62 is fixedly connected to the driving shaft of the second rotation source 61 . The second screw 62 is threadedly connected to the support plate 53 .

[0046] Reference Figure 6 The upper surface of the support plate 53 is detachably connected with a clamp 7 for fastening the wire 21. The clamp 7 is composed of an upper clamp plate 71 and a lower clamp plate 72 which are hinged to each other. The bottom surface of the upper clamp plate 71 is provided with a first clamping groove 711, and the upper surface of the lower clamp plate 72 is provided with a second clamping groove 721. The first clamping groove 711 and the second clamping groove 721 cooperate to fasten the wire 21. The operator opens the clamp 7, moves the wire 21 away from the support wheel 17, and takes out the crimped terminal 2.

[0047] Reference Figure 2 and Figure 8 , the bracket 1 is fixedly connected with a loading block 8, which is arranged at one end of the rotating wheel 12 away from the support ring 31. The loading block 8 is inclinedly provided with a loading groove 81 that can slide the terminal 2, and the lower end of the side wall of the loading block 8 is provided with a discharge groove 83 that can communicate with the inside of the loading groove 81. The bracket 1 is fixedly connected with a third rotating source 91, and the driving shaft of the third rotating source 91 is belt-drivenly connected with a third screw rod 92, and the third screw rod 92 is threadedly connected with a loading plate 191, and the loading plate 191 is slidably connected with the bracket 1. The third rotating source 91 and the third screw rod 92 constitute a third screw rod slider mechanism 9. The upper surface of the loading plate 191 is fixedly connected with a fourth rotating source 84, and the driving shaft of the fourth rotating source 84 is fixedly connected with a material picking member 82 that can clamp the terminal 2 in the loading groove 81. The specific material picking member 82 can be a manipulator or a three-jaw chuck. The manipulator and the three-jaw chuck are existing structures and will not be described in detail here.

[0048] The loading trough 81 can store a plurality of terminals 2, and the bottom terminal 2 is located at the discharge trough 83. The third rotation source 91 drives the pick-up member 82 to move close to the discharge trough 83 through the third screw rod 92 and the loading plate 191, and the pick-up member 82 clamps the terminal 2 in the loading trough 83. The fourth rotation source 84 drives the pick-up member 82 to rotate, so that the pick-up member 82 avoids the loading block 8. The third rotation source 91 drives the pick-up member 82 to move close to the crimping block 16 through the third screw rod 92 and the loading plate 191, and the pick-up member 82 transports the terminal 2 to the crimping block 16 to realize automatic loading of the terminal 2.

[0049] The implementation principle of a high-power terminal crimping device according to an embodiment of the present invention is as follows: before the terminal 2 is crimped, the operator inserts the wire 21 into the support ring 31, the first rotation source 41 moves the sliding plate 3 close to the rotating wheel 12 through the first screw rod 42, the limit ring 32 moves synchronously with the sliding plate 3, the crimping block 16 pushes the limit ring 32 to move, so that the limit ring 32 and the side of the support ring 31 close to the crimping block 16 are flush, the first conical surface 322 drives the pressing block 35 to move away from the central axis of the support ring 31 through the limit rod and the first sliding rod 33, and the pressing block 35 expands the inner diameter of the elastic ring 37, so that the copper wire 22 can pass through the elastic ring 37. The copper wire 22 abuts against the tapered inner side surface of the elastic ring 37, and the elastic ring 37 squeezes the copper wire 22 to gradually bend toward the central axis of the wire 21.

[0050] When crimping the terminal 2, the operator inserts the wire 21 into the terminal 2, and then places the terminal 2 into the supporting wheel 17. The first linear drive 13 is started to drive the transmission rack 14 to move downward, and the transmission rack 14 drives the rotating wheel 12 to rotate through the tooth groove 121. The guide groove 122 rotates synchronously with the rotating wheel 12. The guide groove 122 drives the transmission rod 15 to move close to the central axis of the rotating wheel 12. The crimping block 16 moves along the axial direction of the guide rod 18 with the transmission rod 15, so that the crimping surface 162 abuts against the terminal 2 and crimps the terminal 2. At the same time, the stamping portion 161 presses a groove on the surface of the terminal 2.

[0051] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components.
