Description

Technical Field

[0001] This invention relates to the field of wire harness processing equipment technology, specifically to a follow-up contact device and its usage method, and wire harness processing equipment. Background Technology

[0002] During wire harness processing equipment assembly, wire harness clamps and terminal clamps may be at different heights. The abutment mechanism lacks an adaptive adjustment module, making it inconvenient to quickly adjust the installation position and difficult to ensure that the wire harness and terminals are at the same level when crimped. During maintenance, the lack of positioning detection makes it uncertain whether the wire harness clamp abutment mechanism has been turned back to its original position. If the wire harness clamp does not follow the downward pressure during crimping, it may cause wire harness deformation and lead to unqualified crimping.

[0003] Existing follow-up contact devices have complex overall structures, high manufacturing costs, are not lightweight enough, and occupy a large area, which cannot meet the actual needs of wire harness and terminal processing. Summary of the Invention

[0004] To address at least one drawback and deficiency in the prior art, this invention provides a follow-up abutment device with a robust and ingenious structural design, compact and lightweight construction, small footprint, and time-saving and labor-saving replacement or adjustment during use. It is also easy to maintain and significantly improves the yield of wire harness and terminal processing, thereby significantly improving processing and production efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: The follow-up abutting device provided by the present invention includes a first abutting mechanism, the first abutting mechanism includes a limiting component, a first rod body and a support block connected to each other, the limiting component includes a rod-shaped structure and a block-shaped structure connected to each other in a transmission manner, the support block is provided with a first through hole, and the first rod body passes through the first through hole, so that the limiting component can adjust the position of the support block in the axial direction of the first rod body and can limit the displacement of the support block in the axial direction of the first rod body.

[0006] Preferably, the support block is further provided with two radial through holes that communicate with the first through hole. The two radial through holes are located on the same axis. The block structure and the rod structure are respectively a handle and a screw. The first rod body is provided with multiple first limiting through holes along the axial direction. At least one of the first radial through hole, the second radial through hole, and the first limiting through hole is provided with a thread. The handle is connected to the screw for transmission, so that the screw can be screwed into or out of the first limiting through hole and the second radial through hole after passing through the first radial through hole. The displacement is limited by the threaded connection at any point.

[0007] Preferably, the support block also has two radial through holes that communicate with the first through hole. The axes of the two radial through holes are perpendicular. The block structure and the rod structure are a first handle and a first screw connected to each other, and a second handle and a third rod connected to each other. The end of the third rod is provided with a second limiting hole. The end of the first screw is connected to the second limiting hole. The first rod is provided with two rows of third limiting holes and fourth limiting holes along the axial direction. The third limiting holes and the fourth limiting holes communicate with each other radially and are perpendicular. At least one of the second limiting hole, the third limiting hole, and the fourth limiting hole is provided with a thread. The second handle is drivenly connected to the third rod so that the third rod passes through the second radial through hole and then inserts into the fourth limiting hole. The first handle is drivenly connected to the first screw so that the first screw passes through the first radial through hole and then screws into or out of the third limiting hole and the second limiting hole. The displacement is limited by the threaded connection at any point.

[0008] Preferably, the limiting component further includes a clamping block located in the first through hole. The clamping block has a clamping part capable of holding the first rod and a loosening part capable of avoiding the first rod. The rod-shaped structure is threadedly connected to the loosening part so that the clamping part clamps or loosens the first rod.

[0009] Preferably, the support block further comprises a radial through hole communicating with the first through hole, wherein at least one angle between the first through hole and the radial through hole in the depth direction is 0 < α ≤ 90°. The tightening part is provided with a first unthreaded through hole and a second threaded hole, both of which are connected to the radial through hole in the same axial direction. The block structure and the rod structure are respectively the handle and the screw. After the screw passes through the radial through hole and the first unthreaded through hole in sequence, the handle abuts against the edge of the radial through hole, and by rotating the handle, the screw is made to screw into or out of the second threaded hole, so that the clamping part clamps or releases the first rod body.

[0010] Preferably, the limiting component further includes a first locking element and / or a second locking element. The first locking element includes a limiting flange and a clamping plate respectively located at two points on the clamping block, with the limiting flange at the first location abutting against the first supporting end face of the support block. The clamping plate located at the second position is fixed to the second support end face of the support block to limit the displacement of the support block in the axial direction of the first rod body, and / or the clamping plate is fixed to the clamping block and abuts against the second support end face of the support block to limit the displacement of the support block in the axial direction of the first rod body; The second locking component includes a first nut and a second nut. The axial surface of the first rod is provided with an external thread. The outer diameters of the first nut and the second nut are both larger than the first radial through hole, so that the first nut and the second nut can be fitted into the first rod and respectively abut against the first support end face and the second support end face. Alternatively, the first nut and the second nut can be abutted against the first support end face and the second support end face respectively by two washers, both of which are larger than the first radial through hole.

[0011] Preferably, it further includes a detection unit and a frame equipped with a proximity switch. The detection unit is located on a first abutting mechanism, which is rotatably connected to the frame so that the detection unit can move between a first position and a second position on the frame. The first position is the sensing surface of the proximity switch.

[0012] Preferably, it further includes a second abutment mechanism fixedly connected to the frame. The second abutment mechanism includes a second pressure block and at least one section of a second rod. The second pressure block includes a stop bolt and at least one third locking nut. The stop bolt passes through the third locking nut and is screwed into the second rod to be locked by the third locking nut. The axial length of the second abutment mechanism can be adjusted by means of a threaded structure to adjust the depth of the stop bolt screwed into the second rod.

[0013] The method of using the above-mentioned follow-up abutment device includes the following steps: First, the follow-up abutment device is fixedly mounted on the press head of the machine so that the press head and the follow-up abutment device move synchronously. After the machine is started, the press head moves toward the pressing die until the press head abuts the pressing die. At this time, the follow-up abutting device also abuts the clamp that has clamped the workpiece. Subsequently, the press head continues to move after contacting the pressing die. The press head, pressing die, follow-up contact device and fixture move synchronously to complete the pressing action.

[0014] Wire harness processing equipment, including any of the above-mentioned follower-and-connection devices.

[0015] This invention provides a follower-type abutment device and its usage method, as well as wire harness processing equipment. It has the following beneficial effects: (1) The follower abutment device and its usage method of the present invention are used in wire harness processing equipment. The follower abutment device has a stable and ingenious design, a compact and lightweight structure, a small footprint, and is time-saving and labor-saving to replace or adjust during use. It is easy to maintain and the finished product rate of wire harness and terminal processing is significantly improved after use, thus significantly improving the processing and production efficiency.

[0016] (2) The follow-up abutting device and its usage method of the present invention have low manufacturing cost, do not require overall disassembly when repairing and replacing molds, and are easy to operate; the abutting height of the downward pressure can be changed and is easy to adjust.

[0017] The follow-up abutment device of the present invention can be adaptively adjusted according to the actual pressing height required by the wire harness clamp and the terminal clamp. Even if the wire harness clamp and the terminal clamp are at different heights, the installation position can be quickly adjusted. Finally, by using the follow-up abutment device of the present invention, it can be ensured that the wire harness and the terminal are pressed at the same level during the processing, thereby improving the product processing quality and processing efficiency and meeting the needs of irregular shape processing.

[0018] Meanwhile, the first contact mechanism also has a reset detection function to ensure that the first contact mechanism is reset before crimping, effectively avoiding the situation where the wire harness is deformed and the crimping is unqualified when the crimping wire harness clamp does not follow the downward pressure.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0023] Furthermore, the embodiments of the present invention described below and the technical features involved therein can be combined with each other as long as they do not conflict with each other.

[0024] Example 1 like Figures 1-7 As shown, the follow-up abutment device provided by the present invention includes a first abutment mechanism 2. The first abutment mechanism 2 includes a limiting component, a first rod 21 and a support block 22 connected to each other. The limiting component includes a rod-shaped structure and a block-shaped structure. The support block 22 is provided with a first through hole 221, through which the first rod 21 passes, so that the limiting component can adjust the position of the support block 22 in the axial direction of the first rod 21 and can limit the displacement of the support block 22 in the axial direction of the first rod 21. The limiting component can protrude from the support block 22 toward the first rod 21 so as to be limited by the support block 22 or the first rod 21.

[0025] The rod-shaped structure can be a straight cylinder with or without threads, or a straight prism; the block-shaped structure is an adjustment handle, or a hand-tightening handle. The adjustment handle can be a polygonal block or a straight prism that can be turned with the aid of a wrench. The block-shaped structure is located at the end of the rod-shaped structure and protrudes from the support block 22.

[0026] The limiting component includes a clamping block 23 located in the first through hole 221. The clamping block 23 has a clamping part that can hold the first rod 21 and a loosening part that can avoid the first rod 21. The rod-shaped structure is threadedly connected to the loosening part so that the clamping part clamps or loosens the first rod 21.

[0027] The support block 22 is also provided with a radial through hole 222 communicating with the first through hole 221. At least one angle between the first through hole 221 and the radial through hole 222 in the depth direction is 0 < α ≤ 90°. The tightening part is provided with a first unthreaded through hole 236 and a second threaded hole. Both the first unthreaded through hole 236 and the second threaded hole communicate with each other in the same axial direction as the radial through hole 222. Figure 4 As shown, the block structure and the rod structure are a handle 241 and a screw 242, respectively. After the screw 242 passes through the radial through hole 222 and the first unthreaded through hole 236 in sequence, the handle 241 abuts against the edge of the radial through hole 222. By rotating the handle 241, the screw 242 is screwed into or out of the second threaded hole, so that the clamping part clamps or releases the first rod body 21.

[0028] The limiting assembly also includes a clamping block 23 located in the first through hole 221. The clamping block 23 has a clamping part that can hold the first rod 21 and a loosening part that can avoid the first rod 21. The rod-shaped structure is threadedly connected to the loosening part so that the clamping part clamps or loosens the first rod.

[0029] The limiting assembly also includes a first locking element and / or a second locking element, constructed as follows: The first locking element includes limiting flanges 235 and clamping plates 25 respectively located at two points on the clamping block 23. The first and second points are located on the clamping end face below and above the clamping block 23, respectively; in one embodiment, the first point is offset from the clamping end face below the clamping block 23. The limiting flange 235 located at the first point abuts against the first supporting end face of the support block 22. The clamping plate 25 located at the second position is fixed to the second support end face of the support block 22 to limit the axial displacement of the support block 22 in the first rod 21.

[0030] The connection can be configured as follows: the clamping plate 25 is fixed on the clamping block 23 and abuts against the second support end face of the support block 22 to limit the axial displacement of the support block 22 in the first rod 21.

[0031] The second locking element includes a first nut 27 and a second nut 28. The axial surface of the first rod 21 is provided with external threads. The outer diameters of both the first nut 27 and the second nut 28 are larger than the first radial through hole, so that the first nut 27 and the second nut 28 can be fitted onto the first support end face and the second support end face respectively. Alternatively, the first nut 27 and the second nut 28 can be further tightened onto the first support end face and the second support end face by two washers, both of which are larger than the first radial through hole. The external thread of the first rod 21 is right-handed, and both the first nut 27 and the second nut 28 at both ends are tightened with a right-handed thread.

[0032] The follow-up contact device provided by the present invention further includes a detection unit 225 and a frame 1 equipped with a proximity switch. The detection unit 225 is located on a first contact mechanism 2. The first contact mechanism 2 is rotatably connected to the frame 1 so that the detection unit 225 can move between a first position and a second position of the frame. The first position is the sensing surface of the proximity switch.

[0033] The method of using the follower abutment device of the present invention includes the following steps: First, the follower abutment device is fixed on the punch head 5 of the machine so that the punch head 5 and the follower abutment device move synchronously; after the machine is started, the punch head 5 moves toward the pressing die 6 until the punch head 5 abuts against the pressing die 6, at which time the follower abutment device just abuts against the fixture that has clamped the workpiece; then, the punch head 5 continues to move after abutting against the pressing die 6, and the punch head 5, the pressing die 6, the follower abutment device and the fixture move synchronously to complete the wire harness and terminal crimping action.

[0034] The sensor mounting hole 33 passes through the connecting block 3 so that the sensor mounting hole 33, the first position, and the detection part 225 are on the same axis. The sensor mounting hole 33 is equipped with a proximity switch, and the sensing surface is located in the first position. When the detection part 225 is in the first position, it falls into the sensing surface of the proximity switch. The proximity switch can detect the detection part 225 in the first position, indicating that the first abutting mechanism 2 has returned to its original position and can be pressed down normally. When the detection part 225 is in the second position, it is not on the same axis as the sensor mounting hole 33 and the first position. The proximity switch cannot detect the detection part 225 in the first position, indicating that the first abutting mechanism 2 has not returned to its original position. If the first abutting mechanism 2 is pressed down, it may not be able to reach the (wire harness) clamp, causing the wire harness to deform and thus resulting in unqualified crimping. Furthermore, the sensor mounting hole 33 and the detection through hole 226 are located on the same axis. The detection through hole 226 and the second set hole 224 are connected, and the second set hole 224 is the area where the sensing surface of the proximity switch is located. Detecting whether there are fasteners inserted in the second set hole 224 is more reliable and avoids the first abutment mechanism not returning to the first position. If the clamp does not follow the downward pressure during crimping, it may cause the wire harness to deform and thus lead to unqualified crimping.

[0035] The clamping height of the wire harness clamp and terminal clamp can be adaptively adjusted according to the actual pressing height required. Even if the wire harness clamp and terminal clamp are at different heights, the installation position can be quickly adjusted. By using the follow-up abutment device of the present invention, it can be ensured that the wire harness and terminal are crimped at the same level during the processing, thereby improving the product processing quality and processing efficiency and meeting the actual wire harness and terminal crimping processing requirements.

[0036] Example 2 like Figure 9 As shown, the follower abutment device provided by the present invention differs from that of Embodiment 1 in that the support block 22 is further provided with two radial through holes 222 that communicate with the first through hole 221. The two radial through holes 222 are located on the same axis. The first rod body 21 is provided with a plurality of first limiting through holes 213 along the axial direction. At least one of the first radial through hole, the second radial through hole, and the first limiting through hole 213 is provided with a thread. The handle 241 is connected to the screw 242 in a transmission connection so that the screw 242 passes through the first radial through hole and then screws into or out of the first limiting through hole 213 and the second radial through hole. The displacement is limited by the threaded connection at any point.

[0037] Example 3 like Figure 10 As shown, the follower-type abutment device provided by the present invention differs from Embodiment 1 in that the support block 22 is further provided with two radial through holes 222 that communicate with the first through hole 221. The axes of the two radial through holes 222 are perpendicular. The block structure and the rod structure are a first handle and a first screw connected to each other, and a second handle and a third rod connected to each other. The end of the third rod is provided with a second limiting hole 2421. The end of the first screw is connected to the second limiting hole 2421. The first rod 21 is provided with two rows of third limiting holes 21 along the axial direction. 4 and the fourth limiting hole 215, the third limiting hole 214 and the fourth limiting hole 215 are radially interconnected and perpendicular to each other, at least one of the second limiting hole 2421, the third limiting hole 214 and the fourth limiting hole 215 is provided with threads, the second handle is drivenly connected to the third rod so that the third rod passes through the second radial through hole and is inserted into the fourth limiting hole 215, the first handle is drivenly connected to the first screw so that the first screw passes through the first radial through hole and is screwed into or out of the third limiting hole 214 and the second limiting hole 2421, and the displacement is limited by the threaded connection at any point.

[0038] Example 4 like Figures 3-5As shown, based on the structure of Embodiment 1, the follow-up abutment device provided by the present invention further includes a second abutment mechanism 4 fixedly connected to the frame. The second abutment mechanism 4 includes a second pressure block 42 and at least one section of a second rod 41. The second pressure block 42 includes a stop bolt and at least one third locking nut. The stop bolt passes through the third locking nut and is screwed into the second rod 41 to be locked by the third locking nut. The depth of the stop bolt screwed into the second rod 41 can be adjusted by the threaded structure to adjust the axial length of the second abutment mechanism 4. The second pressure block 42 is detachably fixed to the second pressure rod 41. The second pressure block 42 can be designed into different shapes according to the structure of the clamp, or designed as a flexible pressure block, which has a wide range of applications and meets various usage requirements.

[0039] In one embodiment, the first abutting mechanism 2 and the second abutting mechanism 4 have the same structure.

[0040] Example 5 like Figures 1-7 As shown, the follower-type abutment device for wire harness processing equipment provided by the present invention includes a first abutment mechanism 2 and a second abutment mechanism 4. The first abutment mechanism 2 includes a first rod 21 and a support block 22 connected to each other. The support block 22 is axially limited and connected to the first rod 21 through a first adjusting device. The second abutment mechanism 4 is connected to the first abutment mechanism 2 through a connecting block 3. The second abutment mechanism 4 includes a second rod 41, which is arranged parallel to the first rod 21. The first abutment mechanism 2 is a wire harness clamp abutment mechanism, and the second abutment mechanism 4 is a terminal clamp abutment mechanism. When the wire harness clamp abutment mechanism and the terminal clamp abutment mechanism of the follower-type abutment device of the present invention abut against the terminal clamp and the wire harness clamp respectively, the press head 5 drives the pressing die 6 to move down, and the corresponding abutted terminals and wire harnesses are assembled in the pressing die 6, so that the wire harness and terminals are on the same horizontal plane when they are pressed. The first adjusting device is a limiting component.

[0041] The height of the adjustable rod can be adjusted according to the position of the wire harness clamp and the terminal clamp. The abutting end of the rod can be adjusted to a certain position. For example, when the first rod 21 moves down to the bottom position with the press head 5 but still cannot touch the wire harness clamp, the distance between the abutting end of the first rod 21 and the support block 22 can be adjusted to make the distance longer.

[0042] The support block 22 has a vertical first through hole 221 in the middle. After the first rod 21 passes through the first through hole 221, the first rod 21 and the support block 22 are axially limited by a limiting component that passes through them laterally, so as to prevent the first rod 21 and the support block 22 from axially displacing.

[0043] The outer wall of the first rod 21 is connected to the inner wall of the first through hole 221 of the support block 22 by a thread, so that the first rod 21 and the support block 22 can be detachably and fixedly connected. The height position of the first rod 21 extending out of the support block 22 or the height position of the bottom of the first rod 21 to the support block 22 can be adjusted, which is convenient, time-saving and labor-saving.

[0044] like Figures 1-5 As shown, in the follow-up abutment device for wire harness processing equipment provided by the present invention, the support block 22 is a rectangular frame structure, and a radial through hole 222 matching the limiting component is provided on the outer wall of its free end, and an outwardly protruding detection part 225 is provided on the opposite side wall.

[0045] The upper surface of one side of the connecting block 3 is connected to the frame of the stamping head 5, and the lower surface is connected to the top of the second abutting mechanism; the other side of the connecting block 3 is provided with a first connecting groove that matches the detection part 225, and the detection part 225 can be snapped into the first connecting groove. Vertical through-holes 31 are provided on the upper and lower side walls of the first connecting groove, and a matching through-hole 223 is provided on the detection part 225. The first rotating shaft passing through the through-holes 31 and 223 achieves axial limiting hinge between the support block 22 and the connecting block 3. A first locking through hole 32 is provided vertically through the upper side wall of the first connecting groove. The first locking through hole 32 is a threaded hole, and a locking screw inserted therein can achieve a detachable and fixed connection between the support block 22 and the connecting block 3.

[0046] like Figure 1 As shown, the first adjustment device also includes a clamping block 23 and a clamping pressure plate 25. The clamping block 23 includes a bottom limiting flange 235 and a first clamping part 233 and a second clamping part 234 disposed on the limiting flange 235. The first clamping part 233 and the second clamping part 234 are disposed opposite to each other and have a clamping through hole in the middle that matches the first rod body 21. One end of the two is connected to each other, and the other end is not connected to each other. A cut-out 232 penetrating the limiting flange 235 is provided vertically at the unconnected end. After the first clamping part 233 and the second clamping part 234 of the clamping block 23 clamp the first rod body 21, the clamping block 23 can wrap the clamping part of the first rod body 21 and can avoid the loosening part of the first rod body 21. The rod-shaped structure is threadedly connected to the loosening part so that the clamping part clamps or loosens the first rod body.

[0047] The limiting flange 235 abuts against the first support end face of the support block 22 to limit the upward displacement of the first rod 21 within the first through hole 221. This structural design facilitates the adjustment of the position of the first rod 21 and prevents it from loosening after installation.

[0048] The clamping plate 25 has a third through hole in the middle that matches the first rod 21, through which the first rod 21 passes upward. The upper surfaces of the first clamping part 233 and the second clamping part 234 are respectively provided with vertical second threaded holes 237. The clamping plate 25 is fixedly connected to the second threaded holes 237 of the first clamping part 233 and the second clamping part 234 by fasteners to limit the downward displacement of the first rod 21 in the first through hole 221. The clamping plate 25 can be offset from or cover the first through hole 221, so that the clamping plate 25 abuts against the second support end face of the support block 22, and the limiting flange 235 abuts against the first support end face of the support block 22, realizing the detachable and fixed connection of the first rod 21 and the support block 22, and ensuring the stability of the connected structure.

[0049] like Figure 3 As shown, the upper two side walls of the first rod 21 are flat parts 212, and the remaining circular surfaces are threaded parts 211. The two side walls of the first through hole 221 are also provided with a flat structure that fits and matches the flat part 212. The first clamping part 233 near the radial through hole 222 has a first unthreaded through hole 236 that matches the position of the radial through hole 222 in its flat structure. The second clamping part 234 also has a second threaded hole that matches the first unthreaded through hole 236 in the horizontal direction. The limiting component is a hand-tightening screw that passes through the radial through hole 222, the first unthreaded through hole 236 and the second threaded hole in the horizontal direction, so as to realize the detachable locking and fixing between the first rod 21, the support block 22 and the clamping block 23, to prevent the first rod 21 from slipping during use, so as to make the clamping more reliable and the overall structure more compact.

[0050] On the inner sidewall of the connecting end of the first clamping part 233 and the second clamping part 234, there is also a vertically recessed deformation groove 231, which cooperates with the cutting end 232 to further ensure that the first rod body 21 and the clamping block 23 are detachably fixedly connected, which is convenient for adjustment and does not damage the parts, thus extending the service life of the device.

[0051] The first abutting mechanism 2 also includes a first nut 27 and a second nut 28. The first nut 27 and the second nut 28 are screwed in from both ends of the first rod 21 respectively, and abut against the limiting flange 235 and the clamping plate 25 respectively, further ensuring the detachable locking and fixing between the first rod 21, the support block 22 and the clamping block 23, and that the first rod 21 does not loosen during its up-and-down reciprocating operation.

[0052] like Figures 1-3 As shown, a first pressure block 26 is provided at the bottom of the first rod 21. The first pressure block 26 is detachably connected to the bottom of the first rod 21 through a threaded structure. The first pressure block 26 is a flexible pressure block, which facilitates effective contact with the structure to be abutted without causing structural damage, ensuring that the entire abutting process is carried out continuously and effectively, and extending the service life of the device.

[0053] After the first connecting groove and the second connecting groove are connected, they form a double-sided groove that is perpendicular to each other. The detection part 225 of the support block 22 rotates around the first pivot at the corner of the double-sided groove. It can be adjusted to rotate to the first position and the second position of the frame. When the first connecting groove is in the first position and the detection part 225 is in the second position, a part of the rectangular frame structure of the support block 22 is located in the second connecting groove to complete the avoidance. The side wall of the connecting block 3 that passes through the first position is provided with a sensor mounting hole 33 that runs horizontally through it, so that the sensor mounting hole 33, the first position, and the detection part 225 are on the same axis. An infrared sensor is installed in the sensor mounting hole 33. When the detection part 225 rotates to the first position, the detection part 225 falls into the sensing surface of the proximity switch. At this time, it can be detected by the proximity switch located in the sensor mounting hole 33, indicating that the first abutting mechanism 2 has been reset to the original working position and can perform the downward abutting operation.

[0054] When the detection unit 225 rotates to the second position, the proximity switch cannot detect the detection unit 225 in the first position. The detection unit 225 is not on the same axis as the first position and the sensor mounting hole 33. This indicates that the first abutting mechanism 2 has not been reset to its original working position and cannot perform the downward abutting operation. Otherwise, because the first abutting mechanism 2 has not returned to its original position, the downward pressing mechanism 2 may not be able to reach the (wire harness) clamp, resulting in deformation, damage or breakage of the wire harness. This further ensures the coordinated action of the detection and the device, and ensures that the entire downward reciprocating motion continues to be effective.

[0055] The detection unit 225 is also provided with a second locking hole 224 that matches the first locking through hole 32. By inserting locking screws into the first locking through hole 32 and the second locking hole 224, a detachable fixed connection between the support block 22 and the connecting block 3 is achieved. The detection through hole 226 is connected to the second locking hole 224. By detecting whether there are fasteners inserted inside the second locking hole 224, the stability of the connection structure before the entire device is used is further ensured. This avoids the situation where the clamp does not follow the downward pressure when the first abutting mechanism 2 does not return to the first position, which may cause the clamped object to deform, be damaged or broken.

[0056] Example 6 like Figures 3-4As shown, the follow-up abutment device for wire harness processing equipment of the present invention includes a second abutment mechanism 4 further comprising a second pressure block 42, which is detachably and fixedly connected to the bottom of the second rod 41; the second pressure block 42 is a flexible pressure block. The second pressure block 42 includes a stop bolt and at least one third locking nut. The stop bolt passes through the third locking nut and is screwed into the second rod 41. The depth of the stop bolt screwed into the second rod 41 can be adjusted by the threaded structure before being locked by the third locking nut. This method facilitates adjustment of the elongation length of the second rod 41 and ensures the stability of the overall connection structure after adjustment.

[0057] Example 7 like Figure 5 As shown, the second rod 41 has a multi-section connection structure, consisting of two sections including the second rod 41 and the limiting connecting rod 44. The second abutting mechanism also includes a limiting connecting plate 43 and a limiting connecting rod 44, which are respectively connected to the upper and lower sides of the second rod 41. The limiting connecting plate 43 is a horizontal strip-shaped plate, with its front end connected to the bottom of the connecting block 3, and its rear end bottom surface detachably fixed to the second rod 41 by bolts. This structural design achieves an effective detachable fixed connection between the support block 22, the connecting block 3, and the limiting connecting plate 43. Especially when the equipment is under maintenance or the rotary pressing mold 6 is replaced, the first abutting mechanism 2 can be rotated to avoid displacement, making operation easier and saving time and effort.

[0058] The upper end of the limiting link 44 is connected to the bottom of the second rod 41. Its bottom is detachably fixed to the stop bolt through a threaded structure. The bottom length of the second rod 41 can also be precisely and effectively adjusted by adjusting several third locking nuts fitted on the stop bolt.

[0059] The length adjustment of the second rod 41 in the second abutting mechanism 4 of the present invention and the length adjustment structure of the first rod 21 in the first abutting mechanism 2 in Embodiment 1 are both compact in structure and small in area. They can be adjusted independently and can achieve effective and stable adjustment, synergistic effect, and ensure that the entire reciprocating pressing process is carried out continuously and effectively, meeting the actual use requirements of the follow-up abutting device for wire harness processing equipment.

[0060] Example 8 The method of using the follow-up abutment device for wire harness processing equipment according to the present invention includes the following steps: During installation, the follower abutment device is rotated or fixed on the frame 1 of the punch head 5 of the wire harness processing equipment. The frame 1 has a pad, and the height of the pad can be set as needed. The follower abutment device is set on the pad so that the wire harness and the terminal are at the same level when they are crimped.

[0061] Before use, the length of the second rod 41 in the second abutment mechanism 4 and the length of the first rod 21 in the first abutment mechanism 2 in embodiment 1 are precisely adjusted and fixed according to the desired pressing and abutting height.

[0062] The specific process of pressing down and contacting is as follows: The punch head 5 of the wire harness processing equipment moves toward the pressing die 6 to press the die 6. The follower abutment device moves in the pressing direction of the punch head 5 and performs up-and-down reciprocating motion.

[0063] Among them, the first abutting mechanism 2 is a wire harness clamp abutting mechanism, and the second abutting mechanism 4 is a terminal clamp abutting mechanism. When the wire harness clamp abutting mechanism and the terminal clamp abutting mechanism of the follow-up abutting device abut the terminal clamp and the wire harness clamp respectively, the press head 5 drives the pressing die 6 to move down, and the corresponding abutting terminals and wire harnesses are assembled in the pressing die 6, so that the wire harness and terminals are on the same horizontal plane when they are pressed.

[0064] When maintenance is required, the wire harness clamping mechanism 2 can rotate around the first rotating shaft at the corner of the double-sided groove by the support block 22 driving the detection part 225 of the wire harness clamping mechanism 2 through the first connecting groove and the first rotating shaft provided in the rotating shaft mounting hole 31. This realizes the rotation operation around the wire harness clamping mechanism 2, making the replacement of the pressing die time-saving and labor-saving. After the replacement is completed, the wire harness clamping mechanism rotates back to the original working position, waiting to enter the working state, and follows the reciprocating motion of the stamping head 5 up and down synchronously.

[0065] The present invention relates to a follow-up abutment device for wire harness processing equipment and its usage method. The device has low manufacturing cost, does not require overall disassembly during maintenance and mold replacement, and is easy to operate. Its position can be adjusted as needed, and the pressing abutment height can be adjusted precisely and conveniently.

[0066] Example 9 The wire harness processing equipment of the present invention includes a stamping head 5, a pressing die 6, and a follower abutting device as described in any of the above embodiments. The stamping head 5 and the pressing die 6 are arranged opposite to each other, and the follower abutting device is fixedly connected to the stamping head 5.

[0067] In summary, the follower-up abutment device and wire harness processing equipment of the present invention have a stable and ingenious structural design, a compact and lightweight structure, a small footprint, and are time-saving and labor-saving to use, replace and adjust, and easy to maintain. After use, the yield of wire harness and terminal processing is significantly improved, and the processing efficiency is significantly improved, thus meeting the actual needs of follower-up abutment devices in wire harness processing equipment.

[0068] The above are merely embodiments of the present invention. For example, the first abutting mechanism 2 and the second abutting mechanism 4 in the entire device can be used interchangeably; the first pressing block 26 and the second pressing block 42 can be designed into different shapes or as flexible pressing blocks according to the specific clamping structure required for abutment; the first rod 21 and the support block 22 are axially limited by a limiting component that extends laterally into both of them. The limiting component can be a structure that extends from the inside to the outside or a structure that extends from the outside to the inside; the limiting component can protrude from the first rod 21 toward the support block 22 to be limited by the limiting component or the support block 22, thus realizing the follow-up abutting device and its usage method of the present invention.

[0069] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
