Description

Technical Field

[0001] This utility model relates to the field of connecting wire technology, and in particular to a cutting device for connecting wires. Background Technology

[0002] Connecting cables are crucial carriers for data and power exchange, and their waterproof performance directly affects product functionality and lifespan. With the rapid development of modern society and the continuous advancement of technology, people are paying increasing attention to the safety of various electronic products, and the quality and functional requirements of electronic products are also becoming higher. As a carrier for data and power exchange between devices, between devices and machines, and between machines, the importance of connecting cables is self-evident. Moreover, during the production and processing of connecting cables, it is often necessary to cut the length of the connecting cables according to requirements, which necessitates the use of cutting devices to cut the connecting cables.

[0003] However, existing cable cutting equipment can only cut cables to a fixed length, which is insufficient when different lengths of cable are needed, thus presenting certain limitations. Utility Model Content

[0004] The purpose of this invention is to provide a cutting device for connecting wires to solve at least one of the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wire cutting device, comprising a worktable with a placement slot, a U-shaped plate fixedly mounted on the top of the worktable, a fixed box fixedly mounted on the top of the U-shaped plate, two rotating rods rotatably mounted inside the fixed box, a semi-circular gear and a worm gear respectively fixedly mounted on the two rotating rods, a dual-axis motor fixedly mounted inside the fixed box, worm gears fixedly mounted on the two output shafts of the dual-axis motor, and the two worm gears respectively meshing with the two worm gears, and a sliding mechanism slidably mounted on the U-shaped plate. The sliding rod has two toothed plates fixedly installed on it, and the two toothed plates mesh with two semi-circular gears respectively. A connecting plate is fixedly installed at the bottom of the sliding rod, and a cutter is fixedly installed at the bottom of the connecting plate. An adjusting screw is threaded onto the connecting plate and passes through the connecting plate. An L-shaped plate is rotatably installed at one end of the adjusting screw. A groove is formed on the outer wall of the L-shaped plate, and a fixing rod is fixedly installed in the groove. An L-shaped limiting baffle is slidably installed on the fixing rod, and the bottom of the L-shaped limiting baffle extends into the placement groove.

[0006] Preferably, two guide rods are slidably mounted on the U-shaped plate, and the bottom ends of the two guide rods are fixedly connected to the connecting plate. Compression springs are movably sleeved on the two guide rods, and the top ends of the two compression springs are fixedly connected to the U-shaped plate, and the bottom ends of the two compression springs are fixedly connected to the connecting plate.

[0007] Preferably, both compression springs are tin-plated springs.

[0008] Preferably, a rotating handle is fixedly installed at one end of the adjusting screw, and an anti-slip sleeve is fixedly fitted on the rotating handle.

[0009] Preferably, the L-shaped limiting baffle has a through hole, a linear bearing is fixedly installed in the through hole, and the fixing rod passes through the linear bearing and is slidably connected to the inner wall of the linear bearing.

[0010] Preferably, the bottom of the workbench is fixedly equipped with four support legs, and the bottom of each of the four support legs is fixedly fitted with an anti-slip base plate.

[0011] The beneficial effects of this utility model are as follows:

[0012] In this invention, when the L-shaped limiting baffle moves downward and contacts the bottom of the placement groove, driven by the rotation of the dual-axis motor, the connecting wire is pushed to move so that one end of the connecting wire contacts the L-shaped limiting baffle. As the dual-axis motor continues to rotate, the cutter moves downward to cut the connecting wire. When the connecting wire is cut, the semi-circular gear has just completed half a cycle and no longer meshes with the toothed plate. The compression spring returns to its original shape, pulling the cutter and the L-shaped limiting baffle upward out of the placement groove. The worker puts the new connecting wire into the placement groove and pushes the already cut connecting wire to the other side, so that the new connecting wire can be cut again. When it is necessary to cut connecting wires of different lengths, the L-shaped plate and the L-shaped limiting baffle are moved by rotating the handle clockwise, thereby changing the lateral distance between the L-shaped limiting baffle and the cutter, thus cutting connecting wires of different lengths, greatly increasing the applicability of this device.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model provides, for example Figure 1-5The diagram shows a wire cutting device, including a workbench 1 with a placement slot 2. To support the workbench 1 and facilitate its use, four support legs are fixedly installed at the bottom of the workbench 1, and each of the four support legs has an anti-slip base plate fixedly fitted on its bottom. The anti-slip base plate increases the friction between the support legs and the ground, thus making the device more stable on the ground. A U-shaped plate 3 is fixedly installed on the top of the workbench 1, and a fixed box 4 is fixedly installed on the top of the U-shaped plate 3. Two rotating rods 7 are rotatably installed inside the fixed box 4. Four rotating slots are respectively opened on the inner walls of both sides of the fixed box 4. Both ends extend into two rotating slots and are respectively fitted with bearings. The outer rings of the two bearings are respectively fixedly connected to the inner walls of the two rotating slots. Semi-circular gears 9 and worm gears 8 are respectively fixedly fitted on the two rotating rods 7. A dual-axis motor 5 is fixedly installed in the fixed box 4. Worms 6 are fixedly installed on the two output shafts of the dual-axis motor 5, and the two worm gears 6 mesh with the two worm gears 8 respectively. A sliding rod 10 is slidably installed on the U-shaped plate 3. Two toothed plates 11 are fixedly installed on the sliding rod 10, and the two toothed plates 11 mesh with the two semi-circular gears 9 respectively. A connecting plate 13 is fixedly installed at the bottom end of the sliding rod 10. The bottom of the connecting plate 13 is fixedly installed with... The device is equipped with a cutter 15. An adjusting screw 14 is threaded onto the connecting plate 13. To facilitate easier rotation of the handle 16, a handle 16 is fixedly mounted on one end of the adjusting screw 14. An anti-slip sleeve is fixedly fitted onto the handle 16 to prevent slippage and maintain work efficiency. The adjusting screw 14 passes through the connecting plate 13, and an L-shaped plate 17 is rotatably mounted on one end of the adjusting screw 14. A groove 18 is formed on the outer wall of the L-shaped plate 17, and a fixing rod 19 is fixedly mounted within the groove 18. An L-shaped limiting baffle 20 is slidably mounted on the fixing rod 19. To reduce the height of the L-shaped limiting baffle 20... The friction between the fixed rod 19 and the fixed rod 19 is reduced, thereby reducing the wear of the fixed rod 19 and increasing its service life. The L-shaped limiting baffle 20 has a through hole, in which a linear bearing is fixedly installed. The fixed rod 19 passes through the linear bearing and slides through the inner wall of the linear bearing. The bottom of the L-shaped limiting baffle 20 extends into the placement groove 2. By rotating and moving the adjusting screw 14 to the right, the movement of the adjusting screw 14 drives the L-shaped plate 17 and the L-shaped limiting baffle 20 to move, thereby changing the lateral distance between the L-shaped limiting baffle 20 and the cutter 15, thus cutting connecting lines of different lengths, greatly increasing the applicability of this device.

[0021] In order to enable the cutter 15 to automatically return to its original position for the next cut after cutting the connecting line, two guide rods 12 are slidably installed on the U-shaped plate 3, and the bottom ends of the two guide rods 12 are fixedly connected to the connecting plate 13. Compression springs 21 are movably sleeved on the two guide rods 12, and the top ends of the two compression springs 21 are fixedly connected to the U-shaped plate 3, and the bottom ends of the two compression springs 21 are fixedly connected to the connecting plate 13. In order to improve the service life of the compression springs 21, both compression springs 21 are tin-plated springs.

[0022] The working principle of the connecting wire cutting device provided by this utility model is as follows: In the initial state, the compression spring 21 is in a compressed state. When it is necessary to cut the connecting wire, the connecting wire is first placed in the placement groove 2. The dual-axis motor 5 is started. The rotation of the dual-axis motor 5 drives the worm gear 6 to rotate. The rotation of the worm gear 6 drives the worm wheel 8 to rotate. The rotation of the worm wheel 8 drives the rotating rod 7 to rotate. The rotation of the rotating rod 7 drives the semi-circular gear 9 to rotate. The rotation of the semi-circular gear 9 drives the toothed plate 11 to move downward. The movement of the toothed plate 11 drives the sliding rod 10, the connecting plate 13, and the L-shaped limiting baffle 20 to move downward. When the L-shaped limiting baffle 20 moves downward and contacts the bottom of the placement groove 2, the connecting wire is pushed to move so that one end of the connecting wire contacts the L-shaped limiting baffle 20. As the dual-axis motor 5 continues to rotate, it drives the cutter 15 to move downward to cut the connecting wire. When the connecting wire is cut, the semi-circular gear 9 has just completed half a cycle and no longer meshes with the toothed plate 11. The compression spring 21 returns to its original shape, pulling the connecting plate 13, the cutter 15, and the L-shaped limiting baffle 20 upwards out of the placement groove 2. The worker puts the new connecting wire into the placement groove 2 and pushes the already cut connecting wire to the other side, so that the new connecting wire can be cut again. When it is necessary to cut connecting wires of different lengths, turn the rotating handle 16 clockwise. The rotation of the rotating handle 16 drives the adjusting screw 14 to rotate and move to the right. The movement of the adjusting screw 14 drives the L-shaped plate 17 and the L-shaped limiting baffle 20 to move, thereby changing the lateral distance between the L-shaped limiting baffle 20 and the cutter 15, thus cutting connecting wires of different lengths, which greatly increases the applicability of this device.

[0023] Compared with related technologies, the wire cutting device provided by this utility model has the following advantages:

[0024] This utility model provides a wire cutting device. When the dual-axis motor 5 rotates and drives the L-shaped limiting baffle 20 downwards to contact the bottom of the placement groove 2, it pushes the connecting wire so that one end of the connecting wire contacts the L-shaped limiting baffle 20. As the dual-axis motor 5 continues to rotate, it drives the cutter 15 downwards to cut the connecting wire. When the cutting of the connecting wire is completed, the semi-circular gear 9 has just completed half a cycle and no longer meshes with the toothed plate 11. The compression spring 21 returns to its original shape, pulling the cutter 15 and... The L-shaped limiting baffle 20 moves upward out of the placement groove 2. The worker puts the new connecting wire into the placement groove 2 and pushes the already cut connecting wire to the other side, so that the new connecting wire can be cut again. When it is necessary to cut connecting wires of different lengths, the L-shaped plate 17 and the L-shaped limiting baffle 20 are moved by rotating the handle 16 clockwise, which changes the lateral distance between the L-shaped limiting baffle 20 and the cutter 15, thereby cutting connecting wires of different lengths, which greatly increases the applicability of this device.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
