Description

Technical Field

[0001] The utility model relates to the technical field of wire harness connector processing, in particular to a welding tool for a wire harness connector with adjustable angle. Background Art

[0002] An electrical connector is a connection structure for a plug and a wiring harness, including a welding type connector. The existing patent (Announcement No.: CN110899889A) discloses a manual welding auxiliary tooling for welding wire type connectors. The invention sets a wire fixing device and a connector fixing device to limit the wire and the connector respectively, and cooperates with the constructed two-dimensional platform to facilitate the adjustment of the wire position, so that a single person can easily complete the welding work, reduce the workload, reduce the labor cost, and improve the work efficiency. The welding type connector usually requires multiple wire cores and corresponding welding pins for welding, but the wire fixing device in the above technical solution can only fix one wire core at a time. This fixing method requires the wire cores to be fixed one by one during the welding process, which is cumbersome and complicated to operate and reduces the work efficiency. To this end, we propose an angle-adjustable wire harness connector welding tooling. Utility Model Content

[0003] In order to solve the above problems, the utility model provides a wiring harness connector welding tool with adjustable angle.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] In the above solution, a support plate is fixed on the base plate, and the rotating plate is connected to the support plate via a damping shaft.

[0007] In the above scheme, the clamping groove is in a horizontal semi-columnar shape, and the inner wall of the clamping groove is covered with an elastic layer, and the elastic layer is made of polyurethane.

[0008] In the above solution, a clip is provided on the side of the placement plate away from the installation box.

[0009] In the above scheme, a gear is installed in the installation box through the driving shaft, and the side of the gear is meshed with a rack fixed to the installation plate. A support rod is fixed in the installation box, and a sliding sleeve mounted on the support rod is fixed on the rack.

[0010] In the above solution, a locking plate which can move up and down is provided above the gear.

[0011] In the above scheme, an electromagnet is installed on the top of the locking plate, an iron block is provided above the electromagnet, a power module is provided in the installation box, a switch is provided outside the installation box, a limit rod is fixed in the installation box, and both ends of the locking plate slide with the limit rod.

[0012] The advantages and beneficial effects of the utility model are as follows: by setting a rotating plate and a wire limiting mechanism, the angle of the wire limiting mechanism is adjusted by rotating the rotating plate. Compared with the prior art, it is not only convenient to connect the wire with the wire limiting mechanism, but also convenient to weld the wire and the connector at a suitable angle, thereby improving practicality. By setting the wire limiting mechanism, the wire core in the wire harness is laid flat on the placement plate, and then the pressure plate is moved downward so that the pressure plate is tightly pressed on the wire core, so that the wire core is effectively limited. Compared with the prior art, when multiple welding pins and wire cores need to be welded, there is no need to clamp the wire core multiple times.

DETAILED DESCRIPTION

[0018] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0019] See also Figure 1-3 The utility model provides a technical solution: an angle-adjustable harness connector welding tool, comprising a bottom plate 1 with a two-dimensional platform 2 on the top, and a base plate 3 slidably matched on the two-dimensional platform 2;

[0020] Specifically, the two-dimensional platform 2 includes an X-guide rail and a Y-guide rail, a sliding plate is slidably provided on the X-guide rail, the Y-guide rail is fixedly installed on the top of the sliding plate, and the substrate 3 is slidably connected to the Y-guide rail through a slider. By moving the sliding plate and the substrate 3, the substrate 3 can be moved along the X direction and the Y direction respectively, so that the wire can be connected to the connector.

[0021] A rotating plate 6 is movably provided on the base plate 3, and a wire limiting mechanism 5 is provided on the rotating plate 6;

[0022] Furthermore, a support plate 4 is fixed on the base plate 3, and a rotating plate 6 is connected to the support plate 4 via a damping shaft 7; the damping shaft 7 is used to not only enable the rotating plate 6 to rotate relative to the support plate 4, but also enable the rotating plate 6 to stop freely at any position, wherein the rotating plate 6 is made of aluminum alloy, which has a light weight, good strength, and certain flame retardant properties;

[0023] Specifically, by providing a rotating plate 6 and a wire limiting mechanism 5, the angle of the wire limiting mechanism 5 is adjusted by rotating the rotating plate 6. Compared with the prior art, it is not only convenient to connect the wire with the wire limiting mechanism 5, but also convenient to weld the wire and the connector at a suitable angle, thereby improving practicality.

[0024] The wire limiting mechanism 5 includes a placement plate 52 fixed to the rotating plate 6, the placement plate 52 is fixed to the top surface of the rotating plate 6, a pressing plate 51 connected to the rotating plate 6 by bolts 55 is provided above the placement plate 52, and screw holes matching with the bolts 55 are provided on the rotating plate 6 so as to facilitate the installation of the bolts 55, and a plurality of mutually docking clamping grooves 53 are provided on the placement plate 52 and the pressing plate 51, if there are multiple wire cores, the wire cores can be placed in the clamping grooves 53 one by one, and the wire core heads are exposed from the clamping grooves 53 for a certain length to facilitate welding;

[0025] Furthermore, the clamping groove 53 is in a horizontal semi-columnar shape, and the inner wall of the clamping groove 53 is covered with an elastic layer 54, and the elastic layer 54 is made of polyurethane, which is insulating and flame-retardant and is suitable for use here;

[0026] Specifically, after the placement plate 52 and the pressure plate 51 are pressed tightly, the clamping groove 53 is connected and assembled into a complete column, which is the same shape as the wire core. The elastic layer 54 is used to fill the gap between the thinner wire core and the inner wall of the clamping groove 53, and the elasticity of the elastic layer 54 is used to apply a pre-tightening force to the wire core, thereby effectively limiting the wire core.

[0027] Furthermore, a clamp 56 is provided on the side of the placement plate 52 away from the installation box 8. The clamp 56 is used to clamp the wire. The clamp 56 is placed horizontally, and the clamping plate located below the clamp 56 is fixedly connected to the rotating plate 6. When in use, the clamp 56 can be opened by pressing the upper clamping plate, and the wire is placed in the opening of the clamp 56, so as to limit the unstripped part of the wire, prevent the stripped part of the wire from being pulled during welding, and avoid the wire from being disconnected;

[0028] Specifically, by setting the wire limiting mechanism 5, the wire core in the wire harness is laid flat on the placement plate 52, and then the pressure plate 51 is moved downward so that the pressure plate 51 is tightly pressed on the wire core, so that the wire core is effectively limited. Compared with the prior art, when multiple welding needles and wire cores need to be welded, there is no need to clamp the wire core multiple times. After a single clamping, the wires and welding needles can be directly welded one by one, which reduces the cumbersome clamping steps and improves the welding efficiency.

[0029] A connector fixing mechanism is provided on the bottom plate 1, and the connector fixing mechanism includes a mounting box 8 fixed on the bottom plate 1, and a mounting plate 9 which can be adjusted up and down is provided on the mounting box 8, and a moving opening is provided on the top of the mounting box 8, and the connector is connected to the mounting plate 9 by fasteners;

[0030] Further, a gear 11 is installed in the installation box 8 through a drive shaft 10, one end of the drive shaft 10 passes through the installation box 8, and a rotary handle is fixed to the end of the drive shaft 10 outside the installation box 8, a rack 12 fixed to the installation plate 9 is meshed with the side of the gear 11, and the rack 12 and the installation plate 9 form a C-shape with the opening facing downward, a support rod 13 is vertically fixed in the installation box 8, and a sliding sleeve 14 sleeved on the support rod 13 is fixed on the rack 12;

[0031] Specifically, the drive shaft 10 is rotated, the gear 11 rotates, and drives the rack 12 to move up and down. The sliding sleeve 14 and the support rod 13 are used to make the mounting plate 9 move up and down stably, so that the height of the welding pin on the connector is adapted to the wire core for welding.

[0032] Furthermore, a locking plate 15 that can move up and down is provided above the gear 11; by moving the locking plate 15 downward, the locking plate 15 and the gear 11 are pressed against each other, so that the gear 11 is locked, so that the height of the locking mounting plate 9 remains unchanged, thereby ensuring the stability of welding.

[0033] Further, an electromagnet 16 is installed on the top of the locking plate 15, and an iron block 19 fixed to the inner wall of the top of the installation box 8 is provided above the electromagnet 16. A power module 17 is provided in the installation box 8, and a switch 18 is provided on the outside of the installation box 8. A limit rod 20 is fixed in the installation box 8, and both ends of the locking plate 15 are slidably matched with the limit rod 20. In practical applications, the installation box 8 can be set to be transparent so as to observe the internal situation of the installation box 8;

[0034] Specifically, the switch 18 is connected to the power module 17 and the electromagnet 16 respectively. When the gear 11 needs to be locked, the switch 18 is disconnected, the circuit is disconnected, and the electromagnet 16 is not magnetic. Therefore, the locking plate 15 naturally falls along the limit rod 20 under the action of gravity until it abuts against the gear 11. At this time, the gear 11 is locked. When the gear 11 needs to be adjusted, the switch 18 is turned on to make the circuit conductive. The electromagnet 16 is magnetic, so the electromagnet 16 will move upward along the limit rod 20 and adsorb on the iron block 19, thereby keeping the locking plate 15 away from the gear 11.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
