[0002] A car's power steering system is a system that uses power generated by an electric motor to assist the driver in steering operations. The electronic control unit (ECU) of the power steering system plays a crucial role in the safety and stability of the car's steering. Specifically, the ECU mainly consists of a control board, which typically has various connectors to facilitate the transmission of current and signals.

[0003] Typically, connectors are connected to the control board via crimping, a method that is both convenient and highly efficient. A crimping fixture is a specialized device for performing the crimping operation. Specifically, the crimping fixture includes an upper die and a lower die.

Detailed Implementation

[0051] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0052] To address the issue of crimping fixtures failing to achieve proper alignment and crimping of the control board and connectors, refer to... Figures 1 to 13 As shown, this embodiment provides a crimping fixture, including an upper mold structure 100 and a lower mold structure 200.

[0053] The upper mold structure 100 is disposed on one side of the lower mold structure 200. An operating space for pressing the first and second parts to be pressed is formed between the upper mold structure 100 and the lower mold structure 200. The upper mold structure 100 can be moved to the pressing position in the direction close to the lower mold structure 200 under external drive so as to press the first part to be pressed onto the second part to be pressed.

[0054] A first positioning structure 300 is provided between the upper mold structure 100 and the lower mold structure 200. A second positioning structure 400 for positioning and connecting with the first piece to be pressed is provided on the side of the upper mold structure 100 near the lower mold structure 200. A third positioning structure 500 for positioning and connecting with the second piece to be pressed is provided on the side of the lower mold structure 200 near the upper mold structure 100.

[0055] In specific implementation, refer to Figure 1 As shown, the upper mold structure 100 is located on one side of the lower mold structure 200, which can be understood as the lower side. That is, the upper mold structure 100 and the lower mold structure 200 can be arranged in the vertical direction, with the upper mold structure 100 located on the upper side of the lower mold structure 200. In this case, the space between the upper mold structure 100 and the lower mold structure 200 in the vertical direction can form an operating space. During pressing, the first and second parts to be pressed can be placed in the operating space from top to bottom, so that when the upper mold structure 100 moves downward to the pressing position under external drive, the first and second parts to be pressed can be reliably pressed together.

[0056] Alternatively, in other implementations, the upper mold structure 100 being located on one side of the lower mold structure 200 can also be understood as the left or right side, meaning that the upper mold structure 100 and the lower mold structure 200 can be set along the left-right direction.

[0057] For example, the external drive can be the driving force provided by an external compressor or the gravity provided by other heavy objects.

[0058] Specifically, in this embodiment, a first positioning structure 300 is provided between the upper mold structure 100 and the lower mold structure 200, thereby achieving positioning alignment between the upper mold structure 100 and the lower mold structure 200. Simultaneously, a second positioning structure 400 for positioning and connecting with the first component to be pressed is provided on the side of the upper mold structure 100 near the lower mold structure 200, thereby achieving positioning alignment between the upper mold structure 100 and the first component to be pressed. Furthermore, a third positioning structure 500 for positioning and connecting with the second component to be pressed is provided on the side of the lower mold structure 200 near the upper mold structure 100, thereby achieving positioning alignment between the lower mold structure 200 and the second component to be pressed.

[0059] In other words, in this embodiment, by aligning the upper mold structure 100 and the lower mold structure 200, aligning the upper mold structure 100 with the first piece to be pressed, and aligning the lower mold structure 200 with the second piece to be pressed, accurate positioning between the first piece to be pressed and the second piece to be pressed can be achieved. After the first piece to be pressed and the second piece to be pressed are reliably aligned, the upper mold structure 100 is moved to the pressing position by external drive to perform the pressing operation. At this time, the first piece to be pressed and the second piece to be pressed can be aligned and pressed, thereby improving the alignment effect of the pressing and the yield of the pressing operation.

[0060] Furthermore, in this embodiment, the pressing position specifically refers to the position where the upper mold structure 100 moves to a position where it can make abutting contact with the lower mold structure 200 and is sufficient to press the first pressing member and the second pressing member together.

[0061] For example, in this embodiment, the first component to be crimped can be a control board or other components to be crimped, and the second component to be crimped can be a connector or a housing with connectors assembled, etc. The crimping fixture in this embodiment can achieve reliable alignment and crimping of the control board and the connector.

[0062] The crimping fixture in this embodiment includes an upper die structure 100 and a lower die structure 200. By setting the upper die structure 100 on one side of the lower die structure 200, an operating space for crimping the first and second parts to be crimped is provided between the upper die structure 100 and the lower die structure 200. The upper die structure 100 can be moved to the crimping position in a direction close to the lower die structure 200 under external drive, so as to achieve the purpose of crimping the first part to be crimped onto the second part to be crimped. Meanwhile, the crimping fixture of this utility model also includes a first positioning structure 300 disposed between the upper mold structure 100 and the lower mold structure 200, a second positioning structure 400 disposed on the side of the upper mold structure 100 near the lower mold structure 200, and a third positioning structure 500 disposed on the side of the lower mold structure 200 near the upper mold structure 100. First, the positioning alignment between the upper mold structure 100 and the lower mold structure 200 is achieved through the first positioning structure 300. Then, the positioning alignment between the upper mold structure 100 and the first part to be crimped is achieved through the second positioning structure 400. Finally, the positioning alignment between the lower mold structure 200 and the second part to be crimped is achieved through the third positioning structure 500. In this way, it can be ensured that the first part to be crimped and the second part to be crimped can be accurately aligned before crimping, thereby improving the alignment effect and accuracy of the first part to be crimped and the second part to be crimped, and thus improving the yield of the crimping operation.

[0063] Reference Figures 1 to 4 , Figure 10 , Figure 11 As shown, in some embodiments, the first positioning structure 300 includes a first positioning post 310 and a first positioning cylinder 320.

[0064] One of the first positioning post 310 and the first positioning cylinder 320 is disposed on the upper mold structure 100, and the other of the first positioning post 310 and the first positioning cylinder 320 is disposed on the lower mold structure 200. The first positioning post 310 can be inserted into the first positioning cylinder 320 when the upper mold structure 100 moves to the pressing position.

[0065] In other words, when the upper mold structure 100 moves to the pressing position, the first positioning pin 310 can be inserted into the first positioning cylinder 320, thereby ensuring the alignment and fit between the upper mold structure 100 and the lower mold structure 200.

[0066] For example, the first positioning post 310 can be disposed on the upper mold structure 100, and the first positioning cylinder 320 can be disposed on the lower mold structure 200, as detailed below. Figure 1 As shown. Alternatively, in other implementations, the first positioning post 310 can be placed on the lower mold structure 200, and the first positioning cylinder 320 can be placed on the upper mold structure 100.

[0067] Reference Figures 1 to 4 As shown, at least two first positioning posts 310 can be provided, and the at least two first positioning posts 310 are distributed at intervals along the circumference of the crimping fixture. At least two first positioning cylinders 320 are provided, and the first positioning cylinders 320 correspond one-to-one with the first positioning posts 310. Thus, the alignment effect of the upper mold structure 100 and the lower mold structure 200 can be further improved by the cooperation of at least two first positioning posts 310 and at least two first positioning cylinders 320.

[0068] For example, the first positioning post 310 and the first positioning cylinder 320 can both be configured as two, or three, or as follows. Figure 1 The four shown.

[0069] Reference Figure 1 , Figure 10 and Figure 11 As shown, in some embodiments, the first positioning cylinder 320 is disposed on the lower mold structure 200.

[0070] A first mounting hole is provided on the lower mold structure 200 at a position corresponding to the first positioning cylinder 320. The first positioning cylinder 320 is inserted into the first mounting hole, thereby achieving a reliable connection between the first positioning cylinder 320 and the lower mold structure 200.

[0071] For example, the first mounting hole and the first positioning cylinder 320 can be configured to be an interference fit to further improve the connection stability between the two and prevent loosening.

[0072] Reference Figure 10 and Figure 11 As shown, in some embodiments, a limiting sleeve 321 is provided on the outer wall of all first positioning cylinders 320. The limiting sleeve 321 is located outside the first mounting hole and fits against the side of the lower mold structure 200 facing the upper mold structure 100.

[0073] In specific implementation, when multiple first positioning cylinders 320 are used, to ensure that the installation height of all first positioning cylinders 320 is consistent (i.e., the height of the portion of all first positioning cylinders 320 exposed outside the first mounting hole is consistent), a limiting sleeve 321 can be set on the outer wall of the first positioning cylinder 320. When the first positioning cylinder 320 is inserted into the first mounting hole and the limiting sleeve 321 is just attached to the upper surface of the lower mold structure 200, the insertion depth of the first positioning cylinder 320 can be considered as a preset insertion depth. By ensuring that the insertion depth of all first positioning cylinders 320 is the preset insertion depth, the installation height of all first positioning cylinders 320 is consistent. This ensures that the insertion depth of all first positioning pins 310 in the corresponding first positioning cylinders 320 is also the same, thereby achieving stable alignment of the upper mold structure 100 and the lower mold structure 200 and preventing skewing.

[0074] For example, the limiting sleeve 321 and the first positioning cylinder 320 can be integrally formed, or they can be separately formed and then fitted together.

[0075] Reference Figures 1 to 4 As shown, in some embodiments, an oil collection groove 311 is provided on the outer wall of the portion of the first positioning post 310 that is inserted into the first positioning cylinder 320. The oil collection groove 311 can be used to store lubricating oil so that the first positioning post 310 can be smoothly inserted into the first positioning cylinder 320.

[0076] For example, at least two oil collection grooves 311 can be provided, with at least two oil collection grooves 311 spaced apart along the length direction of the first positioning post 310, so as to achieve a lubrication effect by storing sufficient lubricating oil through at least two oil collection grooves 311.

[0077] Reference Figures 1 to 4 As shown, the first positioning post 310 includes a positioning post body 312, a first locking member, and a non-closed first clamp 313. The first clamp 313 is sleeved on the outer wall of the end of the positioning post body 312 away from the first positioning cylinder 320. The first clamp 313 is connected to the upper mold structure 100 or the lower mold structure 200, and the first clamp 313 is locked at both ends by the first locking member.

[0078] In specific implementation, this embodiment uses the example of the first positioning post 310 being disposed on the upper mold structure 100 and the first positioning cylinder 320 being disposed on the lower mold structure 200, as illustrated below:

[0079] A non-closed first sleeve 313 is provided at the end of the positioning column 312 away from the lower mold structure 200. That is, the first sleeve 313 can be in the shape of a "C". At this time, there is a gap between the two ends of the first sleeve 313. After the first sleeve 313 is put on the end of the positioning column away from the lower mold structure 200, the two ends of the first sleeve 313 are locked by the first locking member. At this time, a reliable connection can be achieved between the first sleeve 313 and the positioning column 312. Then the first sleeve 313 is connected to the upper mold structure 100, thereby realizing the indirect connection between the positioning column 312 and the upper mold structure 100.

[0080] For example, the first locking element can be a locking pin or a bolt. In this case, locking holes can be provided at both ends of the first sleeve 313. Before locking, the positioning pin 312 is inserted into the first sleeve 313, and then the locking pin or bolt is passed through the locking holes at both ends of the first sleeve 313 in sequence to lock the first sleeve 313. At this time, the first sleeve 313 and the positioning pin 312 cannot move relative to each other.

[0081] For example, the first clamp 313 and the upper mold structure 100 can be connected by fastening pins or bolts, or they can be connected by snap-fit.

[0082] Reference Figures 1 to 4 , Figure 6 As shown, in some embodiments, the second positioning structure 400 includes at least two positioning guide rods 410. The at least two positioning guide rods 410 are spaced apart along the length direction of the upper mold structure 100 and are both used for insertion and positioning with the first component to be pressed, thereby realizing the positioning and cooperation between the upper mold structure 100 and the first component to be pressed.

[0083] It should be noted that at this time, at least two positioning holes corresponding to the positioning guide rod 410 need to be set on the first plug-in to be connected. The positioning guide rod 410 is inserted into the positioning hole to achieve the positioning alignment between the upper mold structure 100 and the first plug-in to be connected.

[0084] For example, the positioning guide rod 410 can be configured as follows: Figure 6 The two shown can also be set to three or more.

[0085] Reference Figure 6 As shown, in some embodiments, a second mounting hole is provided on the upper mold structure 100 at a position corresponding to the positioning guide rod 410, and the positioning guide rod 410 is inserted into the second mounting hole, thereby realizing the connection and cooperation between the positioning guide rod 410 and the upper mold structure 100.

[0086] For example, in order to improve the connection reliability between the positioning guide rod 410 and the upper mold structure 100, the positioning guide rod 410 can be configured to have an interference fit with the second mounting hole.

[0087] Reference Figure 6 As shown, in some embodiments, the positioning guide rod 410 includes a first guide rod segment 411 and a second guide rod segment 412 connected sequentially along the direction from the upper mold structure 100 to the lower mold structure 200. The end of the first guide rod segment 411 away from the second guide rod segment 412 is connected to the upper mold structure 100. The outer diameter of the first guide rod segment 411 is larger than the outer diameter of the second guide rod segment 412, thereby facilitating the insertion and engagement of the second guide rod segment 412 with its smaller outer diameter with the first member to be pressed. This avoids the problem of forming a large positioning hole on the first member to be pressed, which would affect the structural strength of the first member to be pressed and occupy a large positional space on the first member to be pressed.

[0088] For example, the positioning guide rod 410 can be made of hardened plastic mold steel, which will not scratch the first part to be pressed when it is connected to the first part to be pressed, while ensuring hardness.

[0089] Reference Figure 10 and Figure 11 As shown, in some embodiments, the third positioning structure 500 includes a contour positioning groove 510, the inner contour shape of which is adapted to the outer contour shape of the second part to be pressed, so that the lower mold structure 200 and the second part to be pressed can be initially positioned and aligned by placing the second part to be pressed in the contour positioning groove 510.

[0090] Reference Figure 10 and Figure 11 As shown, in some embodiments, the third positioning structure 500 further includes at least one positioning pin 520 disposed in the contour positioning groove 510. The positioning pin 520 is used to insert and position with the second part to be pressed, so that the lower mold structure 200 and the second part to be pressed can be aligned by inserting and positioning the positioning pin 520 with the second part to be pressed, thereby further improving the alignment accuracy of the lower mold structure 200 and the second part to be pressed.

[0091] For example, the locating pin 520 can be configured as one or as follows: Figure 10 Two or more as shown.

[0092] It should be noted that the second component to be pressed needs to be provided with positioning slots for insertion and positioning with positioning pins 520, and the position and number of positioning slots correspond to the position and number of positioning pins 520.

[0093] Reference Figures 1 to 6As shown, in some embodiments, the upper mold structure 100 includes an upper template assembly 110 and a pressing assembly 120 detachably connected to the upper template assembly 110 on the side near the lower mold structure 200. The upper template assembly 110 can drive the pressing assembly 120 to move under external drive to realize the pressing operation on the first and second pieces to be pressed.

[0094] In addition, by setting the crimping assembly 120 to be detachably connected to the upper template assembly 110, when the crimping assembly 120 is damaged, it is easy to disassemble the crimping assembly 120 for repair or replacement, thereby saving costs.

[0095] Reference Figure 6 , Figure 8 and Figure 9 As shown, when the first component to be crimped is a control board and the second component to be crimped is a connector, the crimping assembly 120 may specifically include a frame 121 connected to the upper template assembly 110, a pin crimping component 122 disposed at the bottom of the frame 121, and a crimping support component 123. The pin crimping component 122 has a central hole 124. When the crimping assembly 120 moves downwards for crimping, the pin crimping component 122 can crimp the control board and connector, allowing the connector pins to pass through the through holes on the control board and into the central hole 124, thus facilitating the smooth insertion of the pins.

[0096] For example, the pin crimping component 122 can be made of hardened plastic mold steel, which has excellent mechanical and processing properties. The center hole 124 can be chamfered, so that the pins on the connector can be smoothly inserted into the center hole 124 without damaging the control board.

[0097] In addition, the crimping support 123 is used to press against the control panel to prevent it from warping. Specifically, in order to adjust the pressing force of the crimping support 123 on the control panel, the crimping support 123 itself is a telescopic component. Specifically, the crimping support 123 includes a support cylinder 125 and a pressure rod 126 sleeved inside the support cylinder 125. A spring is provided between the pressure rod 126 and the inner wall of the support cylinder 125, thereby enabling the pressure rod 126 to move and extend relative to the support cylinder 125.

[0098] For example, multiple pin crimping members 122 can be provided, and the multiple pin crimping members 122 can be arranged in an array. Multiple crimping support members 123 can also be provided, and the multiple crimping support members 123 can be arranged at circumferential intervals along the frame 121.

[0099] Reference Figure 6As shown, in some embodiments, the upper template assembly 110 is provided with a first connection hole, and the crimping assembly 120 is provided with a second connection hole. The crimping assembly 120 is connected to the upper template assembly 110 by a quick-release pin 600 passing through the first connection hole and the second connection hole, thereby realizing quick assembly and disassembly of the crimping assembly 120 and the upper template assembly 110.

[0100] Reference Figure 6 As shown, a connecting block 111 is provided on the upper template assembly 110 at a position corresponding to the second connecting hole, and the first connecting hole is provided on the connecting block 111 to facilitate the connection between the upper template assembly 110 and the pressing assembly 120. For example, the connecting block 111 can be screwed, snapped, or integrally formed with the upper template assembly 110.

[0101] Reference Figure 6 As shown, the first connection hole includes at least two, and the at least two first connection holes are spaced apart along the length direction of the crimping fixture. The second connection hole includes at least two, and the second connection hole corresponds one-to-one with the first connection hole, so as to further improve the connection reliability of the upper module assembly and the crimping assembly 120 through the cooperation of at least two first connection holes and at least two second connection holes.

[0102] Reference Figures 10 to 13 As shown, in some embodiments, one of the upper mold structure 100 and the lower mold structure 200 is provided with a limiting component 700 that can be raised and lowered along the moving direction of the upper mold structure 100. The limiting component 700 can abut against the other of the upper mold structure 100 and the lower mold structure 200 when the upper mold structure 100 moves to the pressing position, so as to ensure that the height between the upper mold structure 100 and the lower mold structure 200 can be kept consistent each time pressing is performed.

[0103] For example, the limiting component 700 can be disposed on the upper mold structure 100 or on the lower mold structure 200. When the limiting component 700 is disposed on the upper mold structure 100, when the upper mold structure 100 moves to the pressing position, the bottom end of the limiting component 700 abuts against the lower mold structure 200. When the limiting component 700 is disposed on the lower mold structure 200, when the upper mold structure 100 moves to the pressing position, the top end of the limiting component 700 abuts against the upper mold structure 100.

[0104] Reference Figures 1 to 13 As shown, in some embodiments, the limiting assembly 700 includes a second clamp 710, a second locking member, and an abutting post 720 for abutting engagement with the other of the upper mold structure 100 and the lower mold structure 200.

[0105] The second sleeve 710 is connected to one of the upper mold structure 100 and the lower mold structure 200. The abutment post 720 is disposed inside the second sleeve 710 and can move relative to the second sleeve 710 to switch at different height positions. The second locking member is used to lock the first and last ends of the second sleeve 710 when the abutment post 720 moves to a preset height position, so as to restrict the movement of the abutment post 720.

[0106] For example, the following explanation uses the limiting component 700 being installed on the lower mold structure 200:

[0107] The second sleeve 710 is connected to the lower mold structure 200. The abutment post 720 is disposed within the second sleeve 710 and can reciprocate relative to the second sleeve 710 along the direction from the lower mold structure 200 to the upper mold structure 100 to adjust its height. When the abutment post 720 is moved to the desired preset height position, the first and last ends of the second sleeve 710 are locked by the second locking member. At this time, the second sleeve 710 and the abutment post 720 are connected together and cannot move relative to each other, thereby limiting the position of the abutment post 720 and ensuring that the abutment post 720 can be reliably maintained at the preset height position.

[0108] Reference Figure 13 As shown, in some embodiments, the second clamp 710 includes a closed sleeve section 711 and a non-closed clamp section 712 connected to the sleeve section 711, with the side of the sleeve section 711 away from the clamp section 712 connected to one of the upper mold structure 100 and the lower mold structure 200.

[0109] A non-closed notch 713 extending circumferentially along the sleeve section 711 is provided between the sleeve section 711 and the hoop section 712.

[0110] In other words, to facilitate a reliable connection between the second clamping sleeve 710 and the lower mold structure 200, the second clamping sleeve 710 can be provided with a sleeve section 711. This sleeve section 711 can be connected to the lower mold structure 200. Specifically, a connecting seat 723 can be integrally formed at the bottom of the sleeve section 711, and the connecting seat 723 is then connected to the lower mold structure 200 by fasteners such as bolts or pins. There are gaps between the two ends of the clamping sleeve section 712 to allow the abutment column 720 to move within the clamping sleeve section 712 to achieve height adjustment.

[0111] In addition, since the first and last ends of the clamping section 712 need to be locked with a second locking element, a non-closed notch 713 needs to be set between the clamping section 712 and the sleeve section 711. The notch 713 is connected to the gap between the first and last ends of the clamping section 712, so as not to affect the connection and locking of the first and last ends of the clamping section 712.

[0112] For example, the length of the notch 713 extending along the circumference of the sleeve section 711 can be greater than a quarter of the circumference of the sleeve section 711 and less than the circumference of the sleeve section 711.

[0113] Reference Figure 13 As shown, in some embodiments, a flexible sleeve 721 is fitted onto one end of the abutment post 720 that is closer to the other of the upper mold structure 100 and the lower mold structure 200, so as to avoid damage caused by hard abutment between the abutment post 720 and the upper mold structure 100 or the lower mold structure 200.

[0114] For example, the flexible tube 721 can be a silicone tube or a rubber tube.

[0115] In addition, to facilitate the movement of the lower mold structure 200, handles 800 can be provided on the lower mold structure 200. Specifically, there are two handles 800, which are respectively located at opposite ends of the lower mold structure 200 along its length. Specifically, the handles 800 can be welded or screwed onto the lower mold base plate 210.

[0116] Reference Figure 13 As shown, the outer wall of the abutment post 720 is provided with a socket 722 for inserting external tools, so that when moving the abutment post 720, the external tools can be inserted into the socket 722, and the abutment post 720 can be moved by handing the external tools.

[0117] In addition, a support block 900 is provided on the lower mold structure 200. The support block 900 is used to support the second part to be pressed. The support block 900 can be fixed to the lower mold structure 200 by bolts. In order to avoid the second part to be pressed, an avoidance slot 910 can also be provided on the support block 900. For example, the support block 900 can be provided as two spaced apart along the length direction of the lower mold structure 200, or three or more can be provided.

[0118] Reference Figures 1 to 13 As shown, this embodiment provides a crimping device, including a press, a machine base, and the crimping fixture described above.

[0119] The lower mold structure 200 is set on the machine base, and the press is connected to the upper mold structure 100 to drive the upper mold structure 100 to move toward or away from the lower mold structure 200, so as to realize the pressing operation of the first and second parts to be pressed.

[0120] The specific structure and implementation principle of the crimping fixture in this embodiment are the same as those of the crimping fixture provided in the above embodiments, and can bring the same or similar technical effects. They will not be described in detail here. For details, please refer to the description of the above embodiments.

[0121] Specifically, the upper mold plate assembly 110 may include an upper mold base plate 112 and an upper mold fixing plate 113, with the upper mold fixing plate 113 connected to the side of the upper mold base plate 112 near the lower mold structure 200. The upper mold fixing plate 113 and the upper mold base plate 112 can be connected by fastening pins, and both the upper mold fixing plate 113 and the upper mold base plate 112 may have mounting through holes 116 that mate with the fastening pins. Furthermore, the upper mold base plate 112 may have a first threaded hole 114 and a first pin hole 115 for engagement with an external press.

[0122] Specifically, the lower mold structure 200 may include a lower mold base plate 210 and a lower mold fixing plate 220 located on the side of the lower mold base plate 210 near the upper mold structure 100. A contour positioning groove 510 may be provided on the lower mold fixing plate 220. A second pin hole 230 and a second threaded hole 240 may be provided on the lower mold base plate 210 to facilitate reliable connection with the machine tool. In addition, the lower mold base plate 210 and the lower mold fixing plate 220 may be connected by pins or bolts.
