Description

Technical Field

[0001] The utility model relates to the technical field of wire harness welding, in particular to a wire harness welding tool. Background Art

[0002] The automotive wiring harness is the core component of the automotive circuit. It is formed by crimping the contact terminal (connector) made of stamped copper with the wire core, and then bundling it through plastic-pressed insulators or external metal shells to connect the circuit. During the production process, the crimping of the terminal and the wire core is usually done by welding.

[0003] In the operation of existing welding equipment, operators need to manually place the terminal to the welding position. Due to the small size and light weight of the terminal, when the operator places the terminal on the welding work plane and releases his hand, or when the terminal is pressed down after the equipment is started, the terminal is easily displaced on the welding work plane. At this time, when welding the wire core of the wire harness and the terminal, it is easy to cause the position of the wire core welding on the terminal to be offset, thereby affecting the welding quality of the wire harness. Utility Model Content

[0004] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a wire harness welding tool.

[0005] The technical solution of this utility model is as follows:

[0006] A wire harness welding tool comprises a workbench and a welding head on its upper side and a pre-pressing device on its rear side, and side pressing devices arranged on both sides of the workbench;

[0007] As the core technical concept of the utility model, the pre-pressing device includes a support frame arranged on the workbench and a pressing mechanism and a material blocking mechanism thereon, the pressing mechanism includes a clamping member that can elastically press against the workbench surface, the material blocking mechanism includes a blocking member vertically arranged on the rear side of the clamping member, the clamping member is configured to press the terminal on the workbench, and the blocking member is configured to press against the insertion end of the terminal.

[0008] It should be noted that the welding head and the side pressure device in the welding tool adopt the existing technology in the existing wire harness welding equipment, and no further description is given here.

[0009] Compared with the existing welding equipment, the present welding tool, through the pre-pressing device arranged on the rear side of the workbench, can press the terminal on the workbench surface under the elastic action of the elastically arranged pressing member when the terminal is placed on the workbench surface, and under the blocking action of the blocking member, the insertion depth of the terminal is controlled, so that the terminal can be pressed on a suitable welding position, and the terminal will not be shifted in position due to its own light weight or vibration generated by equipment startup, thereby ensuring the accuracy of the subsequent wire harness welding position, thereby improving the welding quality of the wire harness.

[0010] In a wire harness welding tool as described above, the front lower part of the clamping piece is a chamfered structure / rounded structure to ensure that the terminal can be clamped and positioned smoothly, accurately and safely, thereby ensuring the smooth progress of the welding process. Specifically, its chamfered or rounded structure can be used as a slope to guide the insertion of the terminal, helping the terminal to enter the predetermined position more smoothly. This design can reduce friction and interference during insertion, allowing the terminal to be placed and clamped on the workbench more easily and accurately. The chamfered or rounded design can also protect the contact part of the terminal from damage. If the front lower part of the clamping piece is a right angle during the insertion and clamping process, the terminal contact part may be scratched or deformed due to the high hardness of the material, affecting the performance of the electrical connection of the wiring harness after it is put into use.

[0011] As a preferred embodiment, the support frame includes a vertically arranged rear upright plate, the blocking member is connected to the rear upright plate through a first connecting member, and the front and rear positions of the blocking member are adjustable so that the insertion depth of the terminal can be adjusted, so that the device can be suitable for terminals of various lengths.

[0012] Furthermore, the support frame also includes a transversely arranged upper support plate, the lower side of which is connected to a connecting plate with adjustable height through a second connecting member, and the clamping member is elastically arranged on the lower side of the connecting plate, so that the device can be suitable for terminals of various thicknesses, and the elastic performance of the clamping member can also be adjusted by adjusting the height of the connecting plate.

[0013] Further preferably, the blocking member is a rectangular plate, and the upper and lower sides of the blocking member are slidably matched with the upper support plate and the workbench respectively to improve the stability of the blocking member's forward and backward movement. Specifically, protrusions are provided at both ends of the upper and lower edges of the blocking member, and sliding grooves are provided on the upper support plate and the workbench corresponding to the protrusions, and the protrusions are slidably matched with the sliding grooves, so that the terminal can be placed in the middle position of the workbench surface.

[0014] Furthermore, the first connecting member includes a first screw rod that is arranged horizontally through the rear vertical plate, and a locking nut is provided on the first screw rod located on the front and rear sides of the rear vertical plate. The second connecting member includes a second screw rod that is arranged vertically through the upper support plate, and a locking nut is provided on the second screw rod located on the upper and lower sides of the upper support plate, so as to realize the positioning and movement of the connecting plate in the height direction and the positioning and movement of the blocking member in the front and rear direction through a simple connecting structure.

[0015] To facilitate disassembly and assembly, the connecting plate and the blocking member are detachably connected to the corresponding screw rods.

[0016] The beneficial effect of the wire harness welding tool of the utility model lies in that, through the pre-pressing device arranged on the rear side of the workbench, when the terminal is placed on the workbench surface, the terminal can be pressed on the workbench surface under the elastic action of the elastically arranged pressing member, and under the blocking action of the blocking member, the insertion depth of the terminal is controlled, so that the terminal can be pressed on a suitable welding position, and the terminal will not cause position displacement due to its own light weight or vibration generated by equipment startup, thereby ensuring the accuracy of the subsequent wire harness welding position, thereby improving the welding quality of the wire harness.

[0024] See also Figure 1 As shown, this embodiment provides a wire harness welding tool, which mainly includes a workbench 1 and a welding head 2 on its upper side and a pre-pressing device 4 on the rear side, as well as a side pressing device 3 arranged on both sides of the workbench 1 and a clamping device 7 arranged on the lower front side of the workbench 1.

[0025] In this embodiment, the clamping device 7 is used to clamp the insulation position of the wire harness body 6 before the terminal 5 and the wire core of the wire harness body 6 are welded. The side pressure device 3 is used to press the two sides of the terminal 5 after the operator places the terminal 5 on the workbench 1 and releases his hands. The welding head 2 is used to press the terminal 5 and the wire core of the wire harness body 6 by the two side pressure devices 3 and the clamping device 7. After that, the terminal 5 and the wire core of the wire harness body 6 are welded and connected. The welding head 2 and the side pressure device 3 are both existing technologies in the existing wire harness welding equipment, and therefore, no further description is given here.

[0026] As the core technical concept of the present utility model, the pre-pressing device 4 is used to pre-press the terminal 5 when the operator places the terminal 5 on the workbench 1 to prevent the terminal 5 from being displaced on the workbench 1 when the operator releases his hand when placing the terminal 5 on the workbench 1, or when the two side pressing devices 3 press down the terminal 5, so as to ensure the accuracy of the subsequent wire harness welding position and improve the welding quality of the wire harness. The structure of the pre-pressing device 4 is described in detail below.

[0027] Combination Figure 2 and Figure 3 The pre-pressing device 4 includes a support frame 41 arranged on the workbench 1 and a pressing mechanism and a material blocking mechanism thereon. The pressing mechanism includes a pressing member 43 that can elastically press against the surface of the workbench 1. The material blocking mechanism includes a blocking member 42 vertically arranged on the rear side of the pressing member 43. The pressing member 43 is configured to press the terminal 5 against the workbench 1, and the blocking member 42 is configured to press against the insertion end of the terminal 5. The welding position of the terminal 5 can be accurately located by the pressing member 43 and the blocking member 42, and the terminal 5 can be pressed against the welding position of the surface of the workbench 1 at the same time. The welding position of the terminal 5 will not be offset, thereby improving the welding quality of the wire harness.

[0028] Specifically speaking about the structure of the support frame 41, the support frame 41 includes a vertically arranged rear upright plate 411 and a transversely arranged upper support plate 412. The lower part of the rear upright plate 411 is arranged on the surface of the workbench 1, and the upper support plate 412 is vertically connected to the upper front side of the rear upright plate 411. The upper support plate 412 is connected to the rear upright plate 411 by welding. The welding device supports the blocking member 42 and the clamping member 43 through the rear upright plate 411 and the upper support plate 412 respectively.

[0029] Specifically speaking of the structure of the rear vertical plate 411 supporting the blocking member 42, the blocking member 42 is connected to the rear vertical plate 411 via a first connecting member, the first connecting member includes a first screw rod arranged transversely through the rear vertical plate 411, the blocking member 42 and the first screw rod are detachably connected to facilitate disassembly and assembly, and locking nuts are provided on the first screw rods located on the front and rear sides of the rear vertical plate 411 for locking the first screw rods to the rear vertical plate 411, so that the installation of the blocking member 42 is more stable.

[0030] In this embodiment, the blocking member 42 is a rectangular plate, and the upper and lower sides of the blocking member 42 are respectively slidably matched with the upper support plate 412 and the workbench 1 to improve the stability of the blocking member 42 moving forward and backward. Specifically, protrusions are provided at both ends of the upper and lower sides of the blocking member 42, wherein the protrusion on the upper side is set upward, and the protrusion on the lower side is set downward. The upper support plate 412 and the workbench 1 correspond to these four protrusions, and four sliding grooves are opened along the moving direction of the blocking member 42, and the protrusions are slidably matched with the sliding grooves, so that the terminal 5 can be placed in the middle position of the table top of the workbench 1. By adjusting the first screw, the four protrusions of the blocking member 42 will slide along the sliding grooves on the upper support plate 412 and the workbench 1, so that the insertion depth of the terminal 5 can be adjusted, so that the device can be suitable for terminals 5 of various lengths.

[0031] Combination Figure 4 In the sliding matching structure of the blocking member 42 and the workbench 1, the two slide grooves on the workbench 1 are the first slide grooves 11, and the two protrusions on the lower side of the blocking member 42 are the first protrusions 421. By adjusting the first screw, the first protrusion 421 will slide horizontally forward and backward along the first slide groove 11, thereby realizing the adjustment of the front and rear position of the blocking member 42.

[0032] Specifically speaking, the upper support plate 412 is connected to a height-adjustable connecting plate 44 on the lower side through a second connecting member, and the clamping member 43 is elastically arranged on the lower side of the connecting plate 44. The second connecting member includes a second screw rod vertically passing through the upper support plate 412, and locking nuts are arranged on the second screw rods on the upper and lower sides of the upper support plate 412. The connecting plate 44 is detachably connected to the second screw rod for easy disassembly and assembly. By adjusting the second screw rod, the connecting plate 44 will move in the height direction, so that the present device can be used for terminals 5 of various thicknesses. At the same time, the elastic performance of the clamping member 43 can also be adjusted by adjusting the height of the connecting plate 44.

[0033] In this embodiment, the clamping member 43 is a rectangular structure, and the lower front part thereof is a chamfered structure or a rounded structure, so as to ensure that the terminal 5 can be smoothly, accurately and safely clamped and positioned, thereby ensuring the smooth progress of the welding process. Specifically, its chamfered or rounded structure can be used as a slope to guide the insertion of the terminal 5, helping the terminal 5 to enter the predetermined position more smoothly. This design can reduce friction and interference during insertion, so that the terminal 5 can be placed and clamped on the workbench 1 more easily and accurately. The chamfered or rounded design can also protect the contact part of the terminal 5 from damage. If the lower front part of the clamping member 43 is a right angle during the insertion and clamping process, the contact part of the terminal 5 may be scratched or deformed due to the high hardness of the material, affecting the performance of the electrical connection of the wiring harness after it is put into use.

[0034] The pre-pressing device 4 realizes the positioning and movement of the connecting plate 44 in the height direction and the positioning and movement of the blocking member 42 in the front-rear direction through a simple connecting structure, thereby improving the working convenience and high efficiency of the welding device.

[0035] The utility model discloses a wire harness welding tool. Through a pre-pressing device 4 arranged at the rear side of a workbench 1, when a terminal 5 is placed on the workbench 1, the terminal 5 can be pressed on the workbench 1 under the elastic action of an elastically arranged pressing member 43, and under the blocking action of a blocking member 42, the insertion depth of the terminal 5 is controlled, so that the terminal 5 can be pressed on a suitable welding position. The terminal 5 will not be positionally shifted due to its own light weight or vibration generated when the equipment is started, thereby ensuring the accuracy of the subsequent wire harness welding position, thereby improving the welding quality of the wire harness.
