Description

Technical Field

[0001] This invention relates to the field of terminal crimping mold technology, and in particular to a cable crimping mold and a cable crimping device. Background Technology

[0002] Cable crimping is a solderless connection technology that achieves a tight connection by applying pressure to the contact area between the conductor and the terminal, shaping it and providing a reliable electrical and mechanical connection over a long period of time.

[0003] Traditionally, the method of cutting the insulation layer on the surface of cables is mostly vertical downward pressing. The insulation layer is cut by the clockwise impact force between the blade and the insulation layer. After a long period of cutting, the clockwise impact force generated between the blade and the insulation layer surface will gradually accumulate, causing damage to the blade surface. As a result, the insulation layer surface will stick. That is, after long-term use, the damaged blade will lead to insufficient cutting of the insulation layer, resulting in some insulation layer that should be removed remaining on the cable surface. Furthermore, during the subsequent peeling process, the roughness of the cut surface of the insulation layer will lead to insulation layer residue, which will affect the crimping of the terminal and the cable. Summary of the Invention

[0004] To address the technical problems of existing cable crimping equipment, which relies on separate steps for insulation removal, waste stripping, and terminal crimping during cable end processing, resulting in incomplete insulation cutting, difficulty in removing residual material after cutting, large cable positioning deviations, and asynchronous terminal feeding and crimping, leading to low overall processing efficiency, insufficient processing accuracy, and poor crimping stability, this invention provides a lower limb structure for a bipedal walking robot that can stand upright.

[0031] As shown in the figure, specific structures and devices are marked in the figure to clearly illustrate the structure of the embodiments of the present invention. However, this is only for illustrative purposes and is not intended to limit the present invention to this specific structure, device and environment. Those skilled in the art can adjust or modify these devices and environments according to specific needs. Detailed Implementation

[0032] The technical solutions of the present invention will now be described with reference to the accompanying drawings. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some well-known technologies. Furthermore, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0033] like Figures 1 to 10 As shown, this embodiment of the invention provides a cable crimping mold, including a mounting plate 11, a lower cutting mechanism, an upper cutting mechanism, a stripping mechanism, and a crimping mechanism.

[0034] The lower cutting mechanism is located at the bottom of the mounting plate 11 and is used to cut off the bottom edge of the outer insulation layer of the cable end.

[0035] The upper cutting mechanism is positioned above the lower cutting mechanism and is used to cooperate with the lower cutting mechanism to cut off the top edge of the outer insulation layer of the cable end and prevent the insulation layer from being incompletely cut off.

[0036] The stripping mechanism is located on one side of the lower cutting mechanism and is used to peel off the cut insulation layer from the cable end to avoid leaving the cut insulation layer on the cable surface.

[0037] The crimping mechanism is mounted on the mounting plate 11 and is used to drive the upper cutting mechanism to operate, and to complete the crimping of the terminal after the insulation layer at the cable end is cut off.

[0038] It should be noted that the present invention uses the cooperation of the lower cutting mechanism and the upper cutting mechanism to perform upper and lower coordinated cutting of the outer insulation layer of the cable end, and then uses the stripping mechanism to peel off the cut insulation layer, and finally uses the crimping mechanism to complete the terminal crimping. In this way, insulation layer cutting, waste material removal and terminal crimping are integrated into the same mold structure, reducing manual transfer operations and improving the continuity of processing and the stability of crimping quality.

[0039] Furthermore, the lower cutting mechanism includes a base plate 21 fixedly installed on the bottom surface of the mounting plate 11. A fixed block 22 is fixedly installed on one side of the upper surface of the base plate 21. A movable block 23 is fixedly installed on one side of the fixed block 22 by bolts. A lifting core 24 is detachably installed inside the movable block 23. A cutting blade holder 25 is provided on the side of the movable block 23 away from the fixed block 22. A lower cutting blade 26 is slidably connected inside the top of the cutting blade holder 25. A small lower jaw 27 is provided on the side of the cutting blade holder 25 away from the movable block 23. A large lower jaw 28 is provided on the side of the small lower jaw 27 away from the cutting blade holder 25. A fixing bolt 29 is provided inside the large lower jaw 28.

[0040] The large lower jaw 28, small lower jaw 27, cutting blade holder 25, moving block 23, and fixed block 22 are arranged coaxially from left to right. One end of the fixing bolt 29 passes through the large lower jaw 28, small lower jaw 27, and cutting blade holder 25 and extends into the interior of the moving block 23. An elastic telescopic member is fixedly installed at the bottom of the lower cutting blade 26, and the elastic telescopic member at the bottom of the lower cutting blade 26 is fixedly connected to the top surface of the cutting blade holder 25.

[0041] In one possible implementation, the large lower jaw 28 and the small lower jaw 27 can be selected and installed according to the specifications of the terminal to be crimped, and fixed in the corresponding position by fixing bolts 29 to meet the crimping requirements of terminals of different sizes.

[0042] In one possible implementation, the fixed block 22, the moving block 23, and the lifting core 24 cooperate with each other to limit and adjust the positions of the cutting blade holder 25, the lower cutting blade 26, the small lower jaw 27, and the large lower jaw 28, so as to adapt to the processing requirements of different cables and terminals.

[0043] It should be noted that when the operator places one end of the cable into the lower cutting area consisting of the cutter holder 25, the lower cutter 26, the small lower jaw 27, and the large lower jaw 28, the lower cutter 26 positions and cuts into the underside of the outer insulation layer of the cable end, providing a lower reference for the subsequent cutting by the upper cutting mechanism 3. By setting replaceable large lower jaw 28 and small lower jaw 27, the positional relationship between the cable end and the terminal can be kept stable under different terminal crimping scenarios, thereby improving the consistency of cutting and crimping.

[0044] Furthermore, the upper cutting mechanism includes a mold frame 31 slidably mounted on the top side of the mounting plate 11. A material unloading rack 32 is fixedly mounted on the bottom surface of the mold frame 31. A lower pressure plate 33 is fixedly mounted on the bottom surface of the material unloading rack 32 away from the mold frame 31. A symmetrical through-cut groove 34 is provided on the surface of the lower pressure plate 33. A connecting rod 35 is slidably connected inside the groove 34. A fixing frame 36 is fixedly connected to the upper surface of one side of the base plate 21. A positioning plate 37 is fixedly connected to the end of the fixing frame 36 away from the base plate 21. A curved groove is symmetrically through-cut on both sides of the positioning plate 37. A positioning spring 38 is fixedly connected to the groove wall of the curved groove. An upper cutting blade 39 is slidably connected inside the curved groove.

[0045] The connecting rod 35 is arranged symmetrically along the vertical central axis of the lower pressure plate 33. The connecting rod 35 is composed of two connecting rods that are fixedly connected at right angles to each other. The bottom end of the connecting rod 35 on the same side is fixedly connected to the top end of the upper cutting blade 39. The connection point between the connecting rod 35 and the upper cutting blade 39 is located inside the arc-shaped groove. The end of the positioning spring 38 away from the wall of the arc-shaped groove is fixedly connected to the connection point between the connecting rod 35 and the upper cutting blade 39.

[0046] The two upper cutting blades 39 move away from each other along the cable surface under the constraint of the arc groove, so as to cooperate with the lower cutting blade 26 to complete the thorough cutting of the insulation layer on the cable surface.

[0047] A cylinder is fixedly mounted on the surface of the mounting plate 11, and the output shaft end of the cylinder is fixedly connected to the mold frame 31 to cause the mold frame 31 to move vertically on the surface of the mounting plate 11.

[0048] The bottom ends of the two upper cutting blades 39 that are close to each other are set as cutting edges. The cutting edges of the two upper cutting blades 39 are in contact with each other at their close ends. The upper cutting blades 39 are arranged axially symmetrically, and both upper cutting blades 39 are located above the lower cutting blade 26.

[0049] It should be noted that during the operation of the crimping device, the mold frame 31 first moves downward under the drive of the cylinder set on the surface of the mounting plate 11, thereby driving the unloading frame 32 and the lower pressure plate 33 to move downward synchronously. As the lower pressure plate 33 descends, the inclined groove wall of the inclined groove 34 abuts against the top of the connecting rod 35, causing the connecting rod 35 to move along the trajectory of the inclined groove 34. Since the bottom end of the connecting rod 35 is fixedly connected to the upper cutting blade 39, and the bottom end of the connecting rod 35 moves within the arc-shaped groove on the positioning plate 37, the connecting rod 35 will synchronously drive the upper cutting blade 39 to move downward while deflecting along the trajectory of the arc-shaped groove when pressing down.

[0050] Furthermore, during the descent, the upper cutting blade 39 gradually compresses the positioning spring 38 and, together with the lower cutting blade 26, clamps the cable end insulation layer located between them; as the upper cutting blade 39 continues to press down, its blade and the blade of the lower cutting blade 26 gradually cut into the interior of the insulation layer until the insulation layer is cut off.

[0051] Furthermore, after completing the top cut, the two upper cutting blades 39 will continue to move around the cable surface along the arc-shaped groove trajectory, thereby extending the cutting trajectory and cooperating with the lower cutting blade 26 to form a more thorough circumferential cut to the insulation layer.

[0052] It should be noted that by symmetrically arranging the two upper cutting blades 39, the radial force generated by unilateral cutting can be offset, preventing the cable from shifting or vibrating due to uneven force during cutting, thereby reducing problems such as slanted cuts or inconsistent cutting depths. Furthermore, the upper cutting blades 39 move along an arc-shaped trajectory around the cable surface, forming a continuous rotary cut. Compared to the traditional straight-up-down punching method, this reduces the instantaneous impact and friction of the blade on the insulation layer, lowers blade wear and jamming risks, and improves cutting integrity and blade life under long-term use.

[0053] Furthermore, the unloading mechanism includes a telescopic cylinder 41 fixedly installed on one side of the upper surface of the base plate 21. A connecting plate 42 is fixedly installed on one side of the output shaft end of the telescopic cylinder 41. A limiting frame 43 is fixedly connected to the side surface of the connecting plate 42 away from the telescopic cylinder 41. An unloading groove 44 is opened through the inside of the limiting frame 43. An arc-shaped plate 45 is rotatably installed on the side surface of the limiting frame 43 away from the lower cutting blade 26. Both ends of the arc-shaped plate 45 near the limiting frame 43 are rotatably connected to limiting rollers 46.

[0054] The connecting plate 42 is slidably connected to the upper surface of the base plate 21. The limiting frame 43 is located on the side of the fixed frame 36 away from the large lower jaw 28. The limiting frame 43 is configured as two, one above the other. The stripping grooves 44 are respectively opened on the two limiting frames 43 and are arranged axially symmetrically. Along the direction of the large lower jaw 28 toward the connecting plate 42, the two stripping grooves 44 are opened in the shape of a frustum and the inner diameter gradually decreases. The arc plate 45 is arranged centrally symmetrically along the surface of the stripping groove 44.

[0055] A torsion spring is provided at the connection between the arc-shaped plate 45 and the limiting frame 43.

[0056] With the center of the stripping trough 44 as a reference, the center of symmetry of the arc plate 45 is offset from the center of the stripping trough 44 so that one end of the arc plate 45 preferentially contacts the surface of the cable.

[0057] It should be noted that when the worker places the cable to be cut into the mold, the end of the cable to be cut will pass through the cutting area formed by the upper cutting blade 39 and the lower cutting blade 26, and continue to extend into the limiting frame 43, exiting through the stripping grooves 44 provided inside the two limiting frames 43. Since the two stripping grooves 44 together form a frustum-shaped channel that gradually narrows along the insertion direction, they can guide and clamp the insulation layer of the cable end to be cut, keeping the cable in a relatively stable centered state when entering the stripping area.

[0058] Furthermore, after the cable extends into the stripping groove 44, it will be located between the arc-shaped plate 45 and the limiting rollers 46. Multiple limiting rollers 46 contact the outer surface of the insulation layer, thereby clamping the insulation layer to be stripped. Since the structural center of the arc-shaped plate 45 is offset relative to the center of the stripping groove 44, one side of the limiting roller 46 will be preferentially pressed and drive the corresponding arc-shaped plate 45 to rotate, thereby causing the other side of the limiting roller 46 to simultaneously press against the cable surface, so as to achieve adaptive clamping.

[0059] In one possible implementation, after the upper cutting blade 39 and the lower cutting blade 26 have removed the cable insulation layer, the telescopic cylinder 41 is activated. Its output shaft retracts and drives the connecting plate 42 to move away from the upper cutting blade 39, while simultaneously driving the limiting frame 43 and its limiting rollers 46 to move synchronously. Since the cut insulation layer is held by the limiting rollers 46, the limiting frame 43 can pull the cut insulation layer away from the cable body when it moves backward, thereby achieving the stripping of the insulation layer.

[0060] Furthermore, the limiting frame 43 is slidably connected to the surface of the two fixing bolts 29. Therefore, the limiting frame 43 is guided and restricted by the fixing bolts 29 during movement, and can move in a straight line along a stable direction to avoid swaying during the stripping process and improve the smoothness and reliability of the stripping action.

[0061] It should be noted that the combination of the stripping groove 44 and the limiting roller 46 not only enables the rapid stripping of the insulation layer after cutting, but also the frustum-shaped stripping groove 44 can form a gradually narrowing cable guide channel, keeping the cable centered in the stripping area, reducing multiple positioning deviations, and thus facilitating the stable clamping of the cut insulation layer by the limiting roller 46, thereby improving the stripping efficiency.

[0062] Furthermore, the crimping mechanism includes a hanging head assembly 51 fixedly installed on the mounting plate 11. An upper punch 52 is fixedly installed on one side surface of the bottom of the hanging head assembly 51. The upper punch 52 is located directly above the large lower jaw 28.

[0063] It should be noted that when the hanging head assembly 51 drives the upper punch 52 to move downward, it can cooperate with the upper and lower cutting mechanisms in sequence to achieve continuous crimping after the cable insulation layer is cut off, while completing the terminal crimping. The operation of the hanging head assembly 51 and the cooperation between the upper punch 52 and the small lower jaw 27 or the large lower jaw 28 to complete the terminal crimping can adopt existing mature structures, which will not be elaborated here.

[0064] like Figure 1 As shown, this embodiment of the invention also provides a cable crimping device, which, based on the above-mentioned cable crimping mold, further includes a feeding mechanism.

[0065] The feeding mechanism includes a feeding cylinder 61 fixedly installed on the top surface of one side of the mounting plate 11. A throttle valve 62 is fixedly connected to the surface of the feeding cylinder 61. A feeding plate 63 is fixedly connected to the output shaft end of one side of the feeding cylinder 61. A feeding claw 64 is fixedly connected to the bottom of the feeding plate 63. A pressure plate 65 is detachably installed on one side of the upper surface of the base plate 21 by bolts.

[0066] The feeding plate 63 is horizontally slidably connected to the surface of the mounting plate 11, and the bottom surface of the feeding claw 64 is slidably connected to the upper surface of the pressure plate 65.

[0067] In one possible implementation, the terminals are arranged in batches above the pressure plate 65. After the insulation layer of the cable end is cut off and stripped, the feeding cylinder 61 is activated, and its output axis extends outward, driving the feeding plate 63 to move horizontally on the surface of the mounting plate 11, and further driving the feeding claw 64 to move synchronously, pushing the terminals located on the pressure plate 65 forward between the upper punch 52 and the cutting knife seat 25, thereby completing the automatic feeding of the terminals.

[0068] Furthermore, the extension and retraction stroke of the output shaft of the feeding cylinder 61 corresponds to pushing one terminal into the crimping station, thus realizing quantitative feeding of terminals and improving the consistency of the crimping cycle. The throttle valve 62 is used to adjust the action speed of the feeding cylinder 61 to adapt to different terminal specifications and feeding rhythm requirements.

[0069] In one possible implementation, the cutting of the cable insulation layer, the peeling of the insulation layer after cutting, and the crimping and feeding of the terminals can be performed sequentially according to a preset program. The hanging head assembly 51, the telescopic cylinder 41, and the feeding cylinder 61 can all be uniformly controlled by the control program of the crimping device to achieve automated continuous operation.

[0070] The working process of this invention can be summarized as follows: the operator first places one end of the cable between the lower cutting mechanism and the upper cutting mechanism, so that the insulation layer to be cut passes through the cutting area and extends into the stripping groove 44 of the stripping mechanism;

[0071] Subsequently, the mold frame 31 moves down, driving the upper cutting blade 39 to cooperate with the lower cutting blade 26 under the guidance of the inclined groove 34 and the arc groove, to perform joint cutting of the insulation layer of the cable end; after the cutting is completed, the telescopic cylinder 41 drives the limiting frame 43 to move backward, and the limiting roller 46 peels the cut insulation layer from the surface of the cable end; then the feeding cylinder 61 pushes the terminal into the crimping station, and finally the hanging head assembly 51 drives the upper punch 52 to press down, so that the terminal is crimped to the exposed conductor of the cable end, completing the cable end processing.

[0072] In summary, the cable crimping mold and cable crimping device provided by the present invention, by setting up a lower cutting mechanism, an upper cutting mechanism, a stripping mechanism, a crimping mechanism and a feeding mechanism, realizes the integrated operation of cutting the insulation layer of the cable end, peeling off the waste insulation after cutting, automatic feeding of the terminal and crimping of the terminal.

[0073] Among them, the upper cutting blade 39 forms a rotating cutting action around the cable surface under the guidance of the arc groove, which can improve the integrity of the insulation layer cutting; the stripping groove 44 cooperates with the limiting roller 46 to quickly complete the stripping of the insulation layer after cutting; the feeding mechanism can quantitatively convey the terminals, thereby improving the overall processing efficiency, crimping stability and equipment automation.

[0074] The beneficial effects of the technical solutions provided in the embodiments of the present invention include at least the following:

[0075] By integrating insulation shearing, waste stripping, and terminal crimping into the same mold, manual transfer and repetitive positioning can be reduced, improving processing efficiency. The coordinated cutting of the upper and lower cutting mechanisms and the arc-shaped guiding motion of the upper cutting blade 39 can improve the integrity of insulation shearing and reduce incomplete cutting and localized tool wear. The cooperation between the stripping groove 44 and the limiting roller 46 can quickly and stably peel the insulation shearing from the cable end after cutting, avoiding residue. The quantitative feeding of terminals by the feeding mechanism 6 can improve the accuracy of terminal feeding into the station and the consistency of crimping cycle, thereby improving the overall quality of automated processing.

Furthermore, to avoid unnecessary misunderstanding of the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
