Description

Technical Field

[0001] The present 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] To transmit electrical signals, various wiring harnesses are often required. These harnesses serve as the overall set of equipment serving a specific group of load sources, such as relay lines, switching devices, and control systems. Traffic theory fundamentally studies the relationship between traffic volume, call loss, and wiring harness capacity. Therefore, wiring harnesses are a crucial concept within traffic theory.

[0003] Currently, in the process of wire harness processing, in order to connect two wire harnesses, welding is generally used for connection. The main welding method is to place the two wire harnesses under the welding head and press down through the welding head to perform welding, 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 in the prior art to fix the wire harness in advance, 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 for using it. Summary of the Invention

[0005] In response to the shortcomings of the existing technology, the present invention provides a fixing mechanism that facilitates the use of the cooperation between the elastic component and the fixing plate to fix the wiring harness without the need for frequent manual fixing or loosening of the wiring harness. At the same time, the adjustment component and the jacking component can be used in the later stage to generate different fixing clamping forces for wiring harnesses of different sizes, thereby improving the adaptability of the fixing mechanism.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0011] The pushing component is arranged at the end of the elastic component and is used to push the elastic component.

[0012] Preferably, a base assembly is provided below the welding head, and the base assembly includes a supporting platform located directly below the welding head, two vertical plates fixedly connected to the side edges of the supporting platform, an arc-shaped plate fixedly connected to the top of the vertical plates, and slots opened on both sides of the arc-shaped plate, and each fixed plate is aligned with the corresponding slot position.

[0013] Preferably, the adjustment assembly includes an adjustment threaded rod rotatably arranged at the top of the outer shell, a moving block threadedly connected to the outer surface of the adjustment threaded rod, an adjustment tooth fixedly connected to the bottom end of the moving block, an incomplete gear meshing with the adjustment tooth and an extrusion strip fixedly connected to one side of the incomplete gear, and the incomplete gear is rotatably arranged inside the outer shell.

[0014] Preferably, the elastic component includes a movable sleeve located below the extrusion strip, a movable rod slidably connected to one end of the movable sleeve, and an extrusion spring located inside the movable sleeve.

[0015] Preferably, the jacking assembly includes a jacking cover threadedly connected to the end of the movable sleeve and a jacking spring sleeved on the outer surface of the movable sleeve, and the jacking cover is always in contact with the extrusion strip under the elastic force of the jacking spring.

[0016] Preferably, an installation component is provided at the end of the shell, and the installation component includes a U-shaped piece plugged into one end of the movable sleeve, installation holes opened at both ends of the U-shaped piece, a groove opened at the top of the installation hole, a mounting threaded rod fixedly connected to the outside of the shell, and a mounting sleeve threadedly connected to one end of the mounting threaded rod through the corresponding mounting hole.

[0017] Preferably, a connecting assembly is provided between the shell and the welding head, and the connecting assembly includes a fixing seat fixedly connected to one side of the welding head, a linkage gear rotatably arranged inside the fixing seat, two clamping rods slidably arranged on the side of the linkage gear, a movable tooth fixedly connected to the clamping rod on the side close to the linkage gear, a connecting cover sleeved on the outside of the fixing seat, clamping grooves opened on both sides of the connecting cover and a horizontal bar fixedly connected to one end of one of the clamping rods passing through the inside of the fixing seat.

[0018] Preferably, the handle assembly includes a rotating column fixedly connected to one end of the outer side of the outer shell and extending from the adjusting threaded rod, a rotating round block rotatably arranged on the outside of the rotating column, a limiting groove opened on one side of the rotating column, a receiving round groove opened on the side of the rotating round block, a positioning round groove opened at one end of the receiving round groove, a fixed column plugged into the inside of the receiving round groove, a limiting ball fixedly connected to one end of the fixed column, a rubber sleeve fixedly connected to the other end of the fixed column, and a limiting strip fixedly connected to one end of the fixed column passing through the positioning round groove.

[0019] Preferably, the adjustment component further includes a limiting tooth fixedly connected to the outer surface of the incomplete gear, and the thickness of the extruded strip gradually increases from one end to the other end.

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

[0021] S1. Place the two wire harnesses on the base assembly, with the joints of the two wire harnesses placed on the support platform, and the joints of the two wire harnesses are 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 clamped into the slot and cooperates with the arc-shaped piece to limit the wiring harness. At the same time, as the welding head moves further downward, the movable rod starts to move along the inside of the movable sleeve, thereby squeezing the squeezing spring. The deformation of the squeezing spring makes the fixed plate cooperate with the base assembly to fix the wiring harness. Then, the welding head welds the wiring harness. After welding is completed, the welding head moves up and the fixed plate no longer fixes the wiring harness, making it easier to remove the wiring harness.

[0023] S3. When faced with wiring harnesses of different sizes, the handle assembly can be used to drive the adjustment threaded rod to rotate, thereby driving the moving block to translate along the inside of the shell. By utilizing the meshing cooperation between the adjustment teeth and the incomplete gear, the extrusion strip gradually further squeezes the ejection cover or further reduces the squeezing of the ejection cover, thereby changing the overall position of the elastic assembly, thereby generating different clamping and fixing forces for wiring 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 up, it will drive the fixing plate away from the wiring harness, making it easier to remove the wiring harness. At the same time, the handle component can be used to drive the adjustment component to move, 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 fixation 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) By rotating the mounting sleeve, the mounting sleeve is separated from the mounting threaded rod, and then the U-shaped piece is moved downward to separate the U-shaped piece from the shell, and then the jacking cover is rotated 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, which has good safety performance. 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] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort 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 facilitates the use of the elastic component 9 and the fixing plate 11 to fix the wire harness, and does not require frequent manual fixing or loosening of 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. As the welding head 4 moves further downward, the elastic component 9 pushes the fixing plate 11. The wire harness is fixed by the fixing plate 11 and the fixing plate 11 is moved to move stably until the welding head 4 completes welding of the two wire harness joints. Then, when the welding head 4 moves upward, the fixing plate 11 is driven away from the wire harness, thereby facilitating the removal of the wire harness. At the same time, the adjustment component 7 can be driven to move by the handle component 12, thereby driving the elastic component 9 and its fixing plate 11 to move, thereby changing the top force generated by the elastic component 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 and avoid welding dislocation and the like due to shaking during welding, but 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 with reference to the accompanying drawings and specific implementation methods.

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

[0042] According to the attached Figure 1-8, comprising 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 provided on the side of the welding head 4, the fixing mechanism comprising: 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 provided 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 provided with a handle component 12 for driving the adjustment component 7 to move; a pushing component 10, the pushing component 10 is provided 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 It drives the welding head 4 downward, thereby synchronously driving the housing 6 to move, so that the fixing plate 11 moves downward and contacts the wiring harness. As the welding head 4 moves further downward, 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. Then, when the welding head 4 moves upward, it will drive the fixing plate 11 away from the wiring harness, making it easier to remove 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 fixation of wiring harnesses of different sizes. This design can not only fix the wiring harness, but also avoid welding dislocation and other phenomena due to shaking during the welding process. At the same time, there is no need to frequently fix or loosen the wiring harness.

[0043] It should be further explained that a base assembly 2 is provided 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 side of the supporting platform 201, an arc-shaped piece 203 fixedly connected to the top of the vertical piece 202, and a slot 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 that it is convenient 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 and the incomplete gear are meshed. 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 changes in 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 too small a fixing force, which cannot achieve a good fixing effect. At the same time, the setting of the limiting 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 bar 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, thereby further compressing the extrusion spring 903, and utilizing the deformation force generated by the extrusion spring 903 to ensure that the fixed plate 11 has 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 bar 704 under the elastic force of the pushing spring 1002; the pushing cover 1001 is squeezed by the extrusion bar 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 bar 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 provided at both ends of the U-shaped piece 801, a groove 803 provided at the top of the mounting hole 802, a mounting threaded rod 804 fixedly connected to the outside 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 shell 6, and then rotate the top cover 1001 to separate the top cover 1001 from the movable sleeve 901. At this time, the top spring 1002 and its extrusion spring 903 can be replaced. During installation, reverse the top cover 1001 so that the top cover 1001 is screwed into the movable sleeve 901, and then dock the U-shaped piece 801 so that the groove 803 slides over the installation threaded rod 804, and then reverse the installation sleeve 805 so that the installation sleeve 805 is screwed into the installation threaded rod 804, and the installation sleeve 805 is 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 fixed seat 501 fixedly connected to one side of the welding head 4, a linkage gear 503 rotatably arranged inside the fixed seat 501, two clamping rods 504 slidably arranged on the side of the linkage gear 503, a movable tooth 505 fixedly connected to the clamping rod 504 near the side of the linkage gear 503, a connecting cover 502 sleeved on the outside of the fixed 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 fixed seat 501; when the fixing mechanism needs to be replaced, the horizontal bar 507 is pulled outward to make the horizontal bar 507 drive the clamping rod 504 to move, and the movable 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 fixed. 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 then the horizontal bar 507 is moved back so that the card rod 504 extends out and engages with the card slot 506. This design makes it 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 interior of the fixing seat 501.

[0049] Furthermore, the handle assembly 12 includes a rotating column 1201 fixedly connected to one end of the outer side of the shell 6 and extending from the adjusting threaded rod 701, 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 fixing column 1206 inserted into the inside of the receiving round groove 1204, a limiting ball 1207 fixedly connected to one end of the fixing column 1206, a rubber sleeve 1208 fixedly connected to the other end of the fixing column 1206, and a limiting bar 1209 fixedly connected to one end of the fixing column 1206 passing through the positioning round groove 1205; when the adjustment assembly 7 needs to be adjusted, the limiting bar 1209 is aligned with the limiting groove 1203 by rotating the rotating round block 1202, and the limiting bar 1209 is pressed inward to When the locking cam 1208 is in engagement with the locking cam 1209, the locking cam 1209 is engaged with the locking cam 1209, and the locking cam 1209 is engaged with the locking cam 1209, thereby temporarily fixing the locking cam 1209.

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

[0051] S1. Place two wire harnesses on the base assembly 2, with the butt joint of the two wire harnesses placed on the carrier 201, and the butt joint of the two wire harnesses 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 the welding operation. Then the fixing plate 11 is stuck in 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 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 used 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 the 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.

[0053] S3. When facing wire harnesses of different sizes, the handle assembly 12 can be used to drive the adjustment threaded rod 701 to rotate, thereby driving the moving block 702 to translate along the inside of the shell 6, and the engagement of the adjustment teeth 706 with the incomplete gear 703 is used to make the extrusion bar 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.

6. The method for using a wire harness welding device according to claim 2, wherein: The specific steps of the method of use are as follows: S1. Place two wire harnesses on the base assembly (2), with the joints of the two wire harnesses placed on the support platform (201), and the joints of the two wire harnesses 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 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 the 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). By utilizing the meshing cooperation between the adjusting teeth (706) and the incomplete gear (703), the extrusion strip (704) gradually further squeezes the top cover (1001) or further reduces 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.
