Description

Technical Field

[0001] The invention relates to the technical field of wire harness welding, in particular to a wire harness welding device and a use method thereof. Background Art

[0002] In order to transmit electrical signals, various wiring harnesses are often needed, and the wiring harness provides the overall service equipment for a certain load source group, such as relay lines, switching devices, control systems, etc. The basic research content of traffic theory is to study the relationship between traffic volume, call loss and wiring harness capacity. Therefore, wiring harness is an important basic concept in traffic theory.

[0003] Currently, in the process of wire harness processing, in order to connect two wire harnesses, welding is generally carried out by a welding machine. The main welding method is to place the two wire harnesses under the welding head and press down the welding head to weld them, so as to achieve a stable connection between the two wire harnesses.

[0004] During the welding process of the above-mentioned welding machine, it is necessary to manually connect the two wire harnesses, then fix them, and then wait for the welding head to move down for welding. However, due to long-term hand-holding, shaking is inevitable during the welding process. Once the hand shakes, problems such as wire harness welding misalignment or poor welding quality are likely to occur. There are also mechanisms for pre-fixing the wire harness in the prior art, but most of them require frequent manual operation of the fixing mechanism to fix or loosen the wire harness, which is relatively cumbersome. For this reason, we propose a wire harness welding device and a method of using it. Summary of the invention

[0020] In a second aspect, the present invention provides a method for using the wire harness welding device as described above, wherein the specific steps of the method are as follows:

[0021] S1. Place two wire harnesses on the base assembly, and place the butt joint of the two wire harnesses on the carrier, and the butt joint of the two wire harnesses is also located directly below the welding head;

[0022] S2. The welding head is driven downward by the telescopic cylinder to prepare for welding operation. Then the fixed plate is inserted into the slot and cooperates with the arc-shaped piece to limit the wiring harness. At the same time, as the welding head moves downward further, the movable rod is driven to move along the inside of the movable sleeve, thereby squeezing the squeezing spring. The deformation of the squeezing spring is utilized to make the fixed plate cooperate with the base assembly to fix the wiring harness. Then the welding head welds the wiring harness. After welding, the welding head moves upward and the fixed plate no longer fixes the wiring harness, thereby facilitating the removal of the wiring harness.

[0023] S3. When facing wire harnesses of different sizes, the handle assembly can be used to drive the adjusting threaded rod to rotate, thereby driving the moving block to translate along the inside of the shell, and the meshing cooperation of the adjusting teeth and the incomplete gear is used to make the extrusion strip gradually further squeeze the top cover or further reduce the squeezing of the top cover, thereby changing the overall position of the elastic assembly, thereby generating different clamping and fixing forces for wire harnesses of different sizes.

[0024] The present invention discloses a wire harness welding device and a method for using the same, which have the following beneficial effects:

[0025] (1) The welding head is driven downward by the telescopic cylinder, so that the fixing plate moves downward and contacts the wiring harness. As the welding head moves further downward, the elastic component pushes the fixing plate, so that the fixing plate stably fixes and clamps the wiring harness until the welding head completes welding at the joint of the two wiring harnesses. Then, when the welding head moves upward, it drives the fixing plate away from the wiring harness, making it easier to remove the wiring harness. At the same time, the adjustment component can be driven to move by the handle component later, thereby driving the elastic component and its fixing plate to move, thereby changing the pushing force generated by the elastic component when the fixing plate fixes the wiring harness, so as to adapt to the fixing of wiring harnesses of different sizes. This design can not only fix the wiring harness and avoid welding dislocation due to shaking during welding, but also eliminate the need to frequently fix or loosen the wiring harness.

[0026] (2) Rotate the mounting sleeve to separate the mounting sleeve from the mounting threaded rod, then move the U-shaped piece downward to separate the U-shaped piece from the housing, and then rotate the jacking cover to separate the jacking cover from the movable sleeve. At this time, the jacking spring and its extrusion spring can be replaced to maintain a good fixing effect of the fixing plate, and also to maintain a good jacking ability of the jacking assembly.

[0027] (3) By moving the limit bar outward, the limit bar is separated from the limit groove. At this time, even if the rotating round block is rotated, the adjusting threaded rod will not rotate abnormally. It has good safety performance in use. After the adjustment component adjusts the position of the elastic component, it can avoid abnormal movement of the elastic component due to accidental contact, making it impossible for the fixed plate to be fixed and clamped well.

DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] The embodiment of the present application provides a wire harness welding device and a method for using the same, and provides a fixing mechanism, which can conveniently use the cooperation of the elastic component 9 and the fixing plate 11 to fix the wire harness, and there is no need to frequently manually fix or loosen the wire harness. At the same time, the adjustment component 7 and the push-up component 10 can be used to cooperate in the later stage to generate different fixing clamping forces for wire harnesses of different sizes, thereby improving the adaptability of the fixing mechanism. The welding head 4 is driven downward by the telescopic cylinder 3, thereby synchronously driving the housing 6 to move, so that the fixing plate 11 moves downward and contacts the wire harness, and with the further downward movement of the welding head 4, the elastic component 9 pushes the fixing plate 11. The wire harness is moved so that the fixing plate 11 can stably fix and clamp the wire harness until the welding head 4 completes welding of the two wire harness joints. Then, when the welding head 4 moves up, it will drive the fixing plate 11 away from the wire harness, so as to facilitate the removal of the wire harness. At the same time, the handle assembly 12 can be used to drive the adjustment assembly 7 to move, thereby driving the elastic assembly 9 and its fixing plate 11 to move, thereby changing the top force generated by the elastic assembly 9 when the fixing plate 11 fixes the wire harness, so as to adapt to the fixation of wire harnesses of different sizes. This design can not only fix the wire harness, but also avoid welding dislocation and the like due to shaking during welding, and also eliminate the need to frequently fix or loosen the wire harness.

[0040] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0041] The embodiment of the invention discloses a wire harness welding device.

[0042] According to the attached Figure 1As shown in Figure 8, it includes a welding machine body 1, a telescopic cylinder 3 fixedly connected to the welding machine body 1, and a welding head 4 fixedly connected to the output end of the telescopic cylinder 3. A fixing mechanism is arranged on the side of the welding head 4, and the fixing mechanism includes: a fixing plate 11, the fixing plate 11 is located on one side of the welding head 4, and the fixing plate 11 is used to clamp and fix the wire harness; an elastic component 9, the elastic component 9 is connected to the upper part of the fixing plate 11, and the elastic component 9 is used to squeeze the fixing plate 11; a shell 6, the end of the elastic component 9 is plugged with the shell 6, the interior of the shell 6 is arranged with an adjustment component 7, and the adjustment component 7 is used to adjust the position of the elastic component 9, and the end of the adjustment component 7 is arranged with a handle component 12 for driving the adjustment component 7 to move; a pushing component 10, the pushing component 10 is arranged at the end of the elastic component 9, and the pushing component 10 is used to push the elastic component 9; through the telescopic cylinder 3 The welding head 4 is driven to move downward, thereby synchronously driving the housing 6 to move, so that the fixing plate 11 moves downward and contacts the wiring harness. With the further downward movement of the welding head 4, the elastic component 9 pushes the fixing plate 11, so that the fixing plate 11 stably fixes and clamps the wiring harness until the welding head 4 completes the welding of the two wiring harnesses at the joint. Then, when the welding head 4 moves upward, it will drive the fixing plate 11 away from the wiring harness, thereby facilitating the removal of the wiring harness. At the same time, the adjustment component 7 can be driven to move by the handle component 12 at a later stage, thereby driving the elastic component 9 and its fixing plate 11 to move, thereby changing the pushing force generated by the elastic component 9 when the fixing plate 11 fixes the wiring harness, so as to adapt to the fixing of wiring harnesses of different sizes. This design can not only fix the wiring harness, but also avoid welding dislocation due to shaking during welding, but also eliminate the need to frequently fix or loosen the wiring harness.

[0043] It should be further explained that a base assembly 2 is arranged below the welding head 4, and the base assembly 2 includes a supporting platform 201 located directly below the welding head 4, two vertical pieces 202 fixedly connected to the sides of the supporting platform 201, an arc-shaped piece 203 fixedly connected to the top of the vertical piece 202, and slots 204 opened on both sides of the arc-shaped piece 203, and each fixing plate 11 is aligned with the corresponding slot 204; the fixing plate 11 can be set as an arc-shaped plate, and when the two wiring harnesses are placed on the supporting platform 201, when the fixing plate 11 is moved down, it is convenient for the fixing plate 11 to just enter the slot 204, so as to cooperate with the arc-shaped piece 203, so as to fix the wiring harness in the center, thereby further improving the docking accuracy of the wiring harness when fixed, and the width dimension of the fixing plate 11 is slightly smaller than the width dimension of the slot 204, so that the fixing plate 11 can enter the inside of the slot 204.

[0044] Furthermore, the adjusting component 7 includes an adjusting threaded rod 701 rotatably arranged at the top of the shell 6, a moving block 702 threadedly connected to the outer surface of the adjusting threaded rod 701, an adjusting tooth 706 fixedly connected to the bottom end of the moving block 702, an incomplete gear 703 meshing with the adjusting tooth 706, and an extrusion strip 704 fixedly connected to one side of the incomplete gear 703, and the incomplete gear 703 is rotatably arranged inside the shell 6; the adjusting component 7 also includes a limiting tooth 705 fixedly connected to the outer surface of the incomplete gear 703, and the thickness of the extrusion strip 704 gradually increases from one end to the other end; the adjusting threaded rod 701 is driven to rotate by the handle assembly 12, and since the moving block 702 will be limited by the shell 6 and will not rotate, the rotating adjusting threaded rod 701 drives the moving block 702 to move, and the adjusting tooth 706 is used to mesh with the incomplete gear 703. The cooperation of the full gear 703 causes the incomplete gear 703 to rotate, thereby driving the extrusion bar 704 to rotate. Due to the shape design of the extrusion bar 704, the extrusion bar 704 is arc-shaped as a whole and changes with the external contour of the incomplete gear 703. At the same time, the pushing component 10 will always push the elastic component 9. When the extrusion bar 704 further squeezes the pushing component 10, the entire elastic component 9 will move downward. When the extrusion bar 704 no longer further squeezes the pushing component 10, the entire elastic component 9 will move upward, thereby changing the elastic force generated by the elastic component 9, so as to better fix wire harnesses of different sizes, avoid excessive fixing force, resulting in damage to the wire harness, or small fixing force, which cannot achieve a good fixing effect. At the same time, the setting of the limit tooth 705 can prevent the adjustment tooth 706 from separating from the incomplete gear 703.

[0045] Furthermore, the elastic component 9 includes a movable sleeve 901 located below the extrusion strip 704, a movable rod 902 slidably connected to one end of the movable sleeve 901, and an extrusion spring 903 located inside the movable sleeve 901; the movable rod 902 moves along the inside of the movable sleeve 901 to further compress the extrusion spring 903, and the deformation force generated by the extrusion spring 903 is utilized to make the fixed plate 11 have a better fixing effect.

[0046] Furthermore, the pushing assembly 10 includes a pushing cover 1001 threadedly connected to the end of the movable sleeve 901 and a pushing spring 1002 sleeved on the outer surface of the movable sleeve 901, and the pushing cover 1001 is always in contact with the extrusion strip 704 under the elastic force of the pushing spring 1002; the pushing cover 1001 is squeezed by the extrusion strip 704, thereby driving the entire elastic assembly 9 to move, and at the same time the pushing spring 1002 is in a compressed state, so that the pushing cover 1001 is always in contact with the extrusion strip 704.

[0047] Furthermore, a mounting assembly 8 is provided at the end of the housing 6, and the mounting assembly 8 includes a U-shaped piece 801 plugged into one end of the movable sleeve 901, mounting holes 802 opened at both ends of the U-shaped piece 801, a groove 803 opened at the top of the mounting hole 802, a mounting threaded rod 804 fixedly connected to the outer side of the housing 6, and a mounting sleeve 805 threadedly connected to one end of the mounting threaded rod 804 passing through the corresponding mounting hole 802; when it is necessary to replace the extrusion spring 903 or the push spring 1002, the mounting sleeve 805 is rotated to separate the mounting sleeve 805 from the mounting threaded rod 804, and then Move the U-shaped piece 801 downward to separate the U-shaped piece 801 from the outer shell 6, and then rotate the push cover 1001 to separate the push cover 1001 from the movable sleeve 901. At this time, the push spring 1002 and its extrusion spring 903 can be replaced. During installation, reverse the push cover 1001 to make the push cover 1001 and the movable sleeve 901 threadedly engaged, and then dock the U-shaped piece 801 to make the groove 803 slide over the installation threaded rod 804, and then reverse the installation sleeve 805 to make the installation sleeve 805 and the installation threaded rod 804 screwed together, and the installation sleeve 805 can be plugged into the installation hole 802.

[0048] Furthermore, a connecting assembly 5 is provided between the housing 6 and the welding head 4, and the connecting assembly 5 includes a fixing seat 501 fixedly connected to one side of the welding head 4, a linkage gear 503 rotatably arranged inside the fixing seat 501, two clamping rods 504 slidably arranged on the side of the linkage gear 503, a moving tooth 505 fixedly connected to the clamping rod 504 near the side of the linkage gear 503, a connecting cover 502 sleeved on the outer side of the fixing seat 501, a clamping groove 506 opened on both sides of the connecting cover 502 and a horizontal bar 507 fixedly connected to one end of one of the clamping rods 504 passing through the inside of the fixing seat 501; when the fixing mechanism needs to be replaced, the horizontal bar 507 is pulled outward so that the horizontal bar 507 drives the clamping rod 504 to move, and the moving tooth 505 is engaged with the linkage gear 503, so that the other clamping rod 504 also moves synchronously until the clamping rod 504 is engaged with the linkage gear 503. 504 is separated from the card slot 506, and then the connecting cover 502 is moved sideways to complete the disassembly. During installation, the open side of the connecting cover 502 is aligned with the fixing seat 501 and inserted, and then the horizontal bar 507 is moved back so that the card rod 504 is extended and engaged with the card slot 506. This design is convenient for users to install or disassemble the entire fixing mechanism. Openings are provided on both sides of the connecting cover 502, one of which is used to expose the horizontal bar 507. A connecting piece (not shown in the figure) is connected between the connecting cover 502 and the shell 6. At the same time, a reset spring (not shown in the figure) can be fixedly connected to the end face of the card rod 504 that is not connected to the horizontal bar 507 and is away from the card slot 506, which is used to drive the card rod 504 to reset. The width of the horizontal bar 507 is larger than the width of the card rod 504 to prevent the horizontal bar 507 from entering the inside of the fixing seat 501.

[0049] Furthermore, the handle assembly 12 includes a rotating column 1201 fixedly connected to one end of the adjusting threaded rod 701 extending to the outer side of the shell 6, a rotating round block 1202 rotatably arranged on the outer side of the rotating column 1201, a limiting groove 1203 opened on one side of the rotating column 1201, a receiving round groove 1204 opened on the side of the rotating round block 1202, a positioning round groove 1205 opened at one end of the receiving round groove 1204, a fixed column 1206 inserted into the receiving round groove 1204, a limiting ball 1207 fixedly connected to one end of the fixed column 1206, a rubber sleeve 1208 fixedly connected to the other end of the fixed column 1206, and a limiting strip 1209 fixedly connected to one end of the fixed column 1206 passing through the positioning round groove 1205; when the adjustment assembly 7 needs to be adjusted, the limiting strip 1209 is aligned with the limiting groove 1203 by rotating the rotating round block 1202, and the limiting strip 1209 is pressed inward to The limiting groove 1203 is engaged, and the fixing column 1206 moves along the positioning circular groove 1205 until the rubber sleeve 1208 abuts against the inner wall of the positioning circular groove 1205, thereby temporarily fixing the limiting strip 1209. At this time, rotating the rotating block 1202 can make the rotating block 1202 drive the rotating column 1201 and its adjusting threaded rod 701 to rotate. When no adjustment is needed in the later stage, the limiting strip 1209 is moved outward to separate the limiting strip 1209 from the limiting groove 1203. At this time, even if the rotating block 1202 is rotated, the adjusting threaded rod 701 will not rotate abnormally, which has good safety performance in use. At the same time, a through hole for communicating the two is provided between the accommodating circular groove 1204 and the positioning circular groove 1205, and the inner diameter size of the through hole is adapted to the outer diameter size of the fixing column 1206, which can prevent the limiting ball 1207 from entering the positioning circular groove 1205 from the inside of the accommodating circular groove 1204.

[0050] A method for using a wire harness welding device, the specific steps of the method are as follows:

[0051] S1, placing two wire harnesses on the base assembly 2, and the butt joint of the two wire harnesses is placed on the carrier 201, and the butt joint of the two wire harnesses is also located directly below the welding head 4;

[0052] S2. The welding head 4 is driven downward by the telescopic cylinder 3 to prepare for welding operation. Then, the fixing plate 11 is inserted into the notch 204 and cooperates with the arc-shaped piece 203 to limit the wiring harness. At the same time, as the welding head 4 moves downward further, the movable rod 902 is driven to start moving along the inside of the movable sleeve 901, thereby squeezing the squeezing spring 903. The deformation of the squeezing spring 903 is utilized to make the fixing plate 11 cooperate with the base assembly 2 to fix the wiring harness. Then, the welding head 4 welds the wiring harness. After welding, the welding head 4 moves upward, and the fixing plate 11 no longer fixes the wiring harness, thereby facilitating the removal of the wiring harness.

[0053] S3. When facing wire harnesses of different sizes, the handle assembly 12 can be used to drive the adjusting threaded rod 701 to rotate, thereby driving the moving block 702 to translate along the inside of the outer shell 6, and the meshing cooperation of the adjusting teeth 706 and the incomplete gear 703 can be used to make the extrusion strip 704 gradually further squeeze the push cover 1001 or further reduce the squeezing of the push cover 1001, thereby changing the overall position of the elastic assembly 9, thereby generating different clamping and fixing forces for wire harnesses of different sizes.

10. A method for using a wire harness welding device according to any one of claims 1 to 9, characterized in that: The specific steps of the method of use are as follows: S1. Place two wire harnesses on the base assembly (2), and place the butt joint of the two wire harnesses on the support platform (201), while the butt joint of the two wire harnesses is also located directly below the welding head (4); S2. The welding head (4) is driven downward by the telescopic cylinder (3) to prepare for welding operation. Then, the fixing plate (11) is inserted into the notch (204) and cooperates with the arc-shaped plate (203) to limit the wiring harness. At the same time, as the welding head (4) moves further downward, the movable rod (902) starts to move along the inside of the movable sleeve (901), thereby squeezing the squeezing spring (903). The deformation of the squeezing spring (903) is utilized to make the fixing plate (11) cooperate with the base assembly (2) to fix the wiring harness. Then, the welding head (4) welds the wiring harness. After welding is completed, the welding head (4) moves upward and the fixing plate (11) no longer fixes the wiring harness, thereby facilitating the removal of the wiring harness. S3. When facing wire harnesses of different sizes, the handle assembly (12) can be used to drive the adjusting threaded rod (701) to rotate, thereby driving the moving block (702) to translate along the inside of the housing (6), and the meshing cooperation between the adjusting teeth (706) and the incomplete gear (703) can be used to make the extrusion strip (704) gradually further squeeze the top cover (1001) or further reduce the squeezing of the top cover (1001), thereby changing the overall position of the elastic assembly (9), thereby generating different clamping and fixing forces for wire harnesses of different sizes.
