Description

Technical Field

[0001] The utility model relates to the technical field of electronic component production, in particular to a tooling fixture for cutting the lead wires of a power supply housing. Background Technique

[0002] The lead wires of a power supply housing are a group of conductors that connect electrical appliances to indoor wiring. These conductors are usually housed inside the electrical appliance or its connection box. Their function is to transmit electric power from the power supply to the electrical equipment to ensure the normal operation of the electrical appliance. This design not only facilitates the installation and use of the electrical appliance but also ensures the safety and efficiency of power transmission.

[0003] The patent with the publication number CN217570665U discloses a tooling fixture for cutting the lead wires of a power supply housing. It includes an operation platform, on which there are a slide rail, a first cutter, and a second cutter. The slide rail and the first cutter are fixed to the operation platform, and the slide rail is perpendicularly connected to the first cutter. One end of the second cutter is rotatably connected to the side of the first cutter away from the slide rail. After the lead wires at one end of the power supply housing are sheared by this tooling fixture, there is no need to disassemble the power supply housing from this tooling fixture. Just pull the slide seat and rotate the rotating seat, and then the lead wires at the other end of the power supply housing can be sheared. The shearing efficiency is high;

[0004] However, this device only has a set of first cutter and second cutter. As a result, after the power supply housing is fixed by the spring clamping structure, it is necessary to use the limit bolt to adjust the position of the slide seat to determine the lead wire cutting position. After cutting, it is also necessary to move the slide seat to separate it from the second cutter to the installation distance and then rotate the slide seat to turn the lead wires at the other end to the cutter end to reposition the cutting position before cutting. The operation is cumbersome and it is inconvenient to quickly cut according to the lead wire cutting requirements. For this reason, a tooling fixture for cutting the lead wires of a power supply housing is proposed to solve the problem that the existing lead wire tooling fixture is difficult to quickly adjust the cutting according to the lead wire cutting position.

SPECIFIC EMBODIMENTS

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0025] Embodiment: Please refer to Figures 1-6, A tooling fixture for cutting the leads of a power supply housing, comprising a workbench 1. A moving seat 2 is arranged at the top of the workbench 1. A power supply housing 3 is arranged at the top of the moving seat 2. A clamping mechanism 4 is arranged at the top of the moving seat 2. A T-shaped groove 5 is formed in the top of the workbench 1. A T-shaped block 6 is arranged in the inner cavity of the T-shaped groove 5. A fixed frame 7 is fixedly connected to the top of one side of the workbench 1. A bidirectional lead screw 8 is arranged between the fixed frames 7. A servo motor 9 is fixedly connected to one end of the fixed frame 7. Two groups of symmetrical moving cylinders 10 are screwed on the outer part of the bidirectional lead screw 8. A rotating ring 11 is rotatably connected to the outer part of one end of the moving cylinder 10. A cutting seat 12 and a cutting tool 13 are respectively fixedly connected to the outer rings of the moving cylinder 10 and the rotating ring 11.

[0026] Furthermore, the clamping mechanism 4 includes two clamping plates 401 arranged at the top of the moving seat 2. A fastening groove 402 is formed in the top of the moving seat 2. Two fastening blocks 403 are arranged in the inner cavity of the fastening groove 402. The fastening blocks 403 are fixedly connected to the clamping plates 401.

[0027] Furthermore, a bidirectional screw 404 is arranged in the inner cavity of the fastening groove 402. The bidirectional screw 404 penetrates through the two fastening blocks 403 and is in threaded connection with them. The bidirectional screw 404 penetrates through the moving seat 2 and the intersection position is rotatably connected by a bearing. A knob 405 is fixedly connected to one end of the bidirectional screw 404. After placing the power supply housing 3 on the moving seat 2, by cooperating with the knob 405 and the bearing, the bidirectional screw 404 is driven to rotate. Then, under the action of the fastening blocks 403 in the fastening groove 402, the two clamping plates 401 are driven to move inwards to clamp the power supply housing 3, achieving the purpose of conveniently fixing according to the size of the power supply housing and improving the applicability of this tooling fixture.

[0028] Furthermore, the T-shaped block 6 is fixedly connected to the moving seat 2. The T-shaped block 6 is slidably connected in the inner cavity of the T-shaped groove 5 and there is a minimum friction force that can keep the moving seat 2 stationary. After the power supply housing 3 is fixed on the moving seat 2 by the clamping mechanism 4, the moving seat 2 can be accurately moved to the middle position between the cutting seats 12 by using the T-shaped block 6 in the T-shaped groove 5. With the cooperation of the friction force between the T-shaped groove 5 and the T-shaped block 6, the position of the moving seat 2 is self-fixed, improving the stability of subsequent lead cutting.

[0029] Furthermore, the servo motor 9 penetrates through the fixed frame 7 and is fixedly connected to the bidirectional lead screw 8. One side of the cutting seat 12 is in contact with the inner cavity of the fixed frame 7 and is slidably connected. The bottom of the cutting seat 12 is in contact with the workbench 1 and can slide freely, while the other side is in contact with the fixed frame 7 and can slide, so as to limit the moving cylinder 10 and prevent the moving cylinder 10 from rotating together with the cutting seat 12 when the bidirectional lead screw 8 rotates, thus affecting the subsequent cutting of the leads.

[0030] Furthermore, both ends of the top of the moving seat 2 are fixedly connected with limiting plates 14. A plurality of limiting grooves 15 are formed in the tops of the limiting plates 14. A fastening pad 16 is arranged in the inner cavity of the limiting groove 15. After the power supply housing 3 is fixed on the moving seat 2, the lead wires can be placed in the limiting grooves 15 at appropriate positions in the limiting plates 14, and clamped according to the lead wire size in cooperation with the fastening pad 16, so as to limit and clamp the lead wires, thereby improving the stability during lead wire cutting.

[0031] Working principle: When using this tooling fixture for cutting the lead wires of the power supply housing, first separate the two groups of moving cylinders 10. After placing the power supply housing 3 on the moving seat 2 and fixing it with the clamping mechanism 4, push it between the cutting seats 12 through the T-shaped blocks 6 in the T-shaped grooves 5. After the 180-degree rotating cutting knife 13 is supported by the fixing frame 7, start the servo motor 9 to drive the movement of the moving cylinders 10 outside the bidirectional lead screw 8, so that the cutting seats 12 are placed at the positions where the lead wires need to be cut. Rotate the cutting knife 13 in cooperation with the rotating ring 11 to cut the lead wires at both ends simultaneously. The structure is simple, and there is no need to move the position of the power supply housing 3 to adjust the lead wire orientation and cutting position, and the operation is convenient, which solves the problem that the existing lead wire tooling fixture is difficult to quickly adjust the cutting according to the lead wire cutting position; if the cutting positions of the lead wires outside the power supply housing 3 are different, the position of the cutting seat 12 can be moved to cut one end of the lead wire, and then continue to adjust the cutting seat 12 at the other end to move it to the cutting position of the lead wire at the other end and cooperate with the cutting knife 13 for cutting, so as to cut the lead wires at different positions at both ends of the power supply housing 3, improving the practicability of this tooling fixture for cutting the lead wires of the power supply housing.
