Description

Technical Field

[0001] This utility model relates to the field of clamps in wire box workshops, and in particular to a clamp for wire box workshops. Background Technology

[0002] Currently, in the production and assembly process of wire harnesses, equipment such as positive and negative electrode cutting and riveting machines and positive and negative electrode three-part separation machines often need to clamp and position the wire harnesses to complete subsequent operations. Traditional clamping methods mostly use fixed jaws or simple manual clamps, which have obvious limitations. First, the clamping force is fixed and cannot be adjusted. When dealing with wire harnesses of different materials and hardness, too little clamping force can easily lead to unstable clamping and loosening of the wire harness, affecting processing accuracy; too much clamping force can easily damage the insulation layer of the wire harness, causing dents or permanent deformation, seriously affecting the product's appearance and electrical safety quality.

[0003] To address the aforementioned issues, this patent proposes an automated gripper that can quickly adapt to different wire diameters, flexibly adjust clamping force, and has anti-damage capabilities. Utility Model Content

[0004] The main purpose of this utility model is to propose a clamping claw for wire box workshops, which aims to solve the problem that traditional clamping claws for wire box workshops use fixed clamping claws, with fixed and non-adjustable clamping force, which easily damages the insulation layer of wire harnesses.

[0005] To address the aforementioned problems, this utility model proposes a wire clamp for a wire box workshop, comprising a wire clamping base, a wire clamping assembly, a quick-release assembly, and a clamping force adjustment assembly. The wire clamping assembly includes an opening / closing motor, a connecting rod, an outer clamping plate, and an inner clamping plate. The upper sides of both ends of the wire clamping base are provided with opening / closing slots. An opening / closing motor is installed inside the lower end of each of the two opening / closing slots. A connecting rod is connected to the outside of each of the two opening / closing motors. An outer clamping plate is connected to the end of each of the two connecting rods away from the opening / closing motor. An inner clamping plate is installed on the upper side of each of the two outer clamping plates. A quick-release assembly is provided between the wire clamping assembly and the wire clamping base, allowing for quick installation and disassembly. A clamping force adjustment assembly is provided between each of the two outer clamping plates and the two inner clamping plates, allowing for adjustment of the clamping force of the wire clamping assembly.

[0006] Preferably, the quick-release assembly includes a disassembly slot and a disassembly block. The lower side of the inner wall at both ends of the opening and closing rotating groove is provided with a disassembly slot, and a disassembly block is provided inside each of the two disassembly slots. The two disassembly blocks are respectively connected to the front and rear ends of the opening and closing motor through the motor shaft.

[0007] Preferably, the disassembly and assembly slot has a connecting slot at the end near the opening and closing motor, and the opening of the connecting slot faces outward, for the motor shaft of the opening and closing motor to connect with the disassembly and assembly block. The disassembly and assembly slot has a limit hole at the end away from the opening and closing motor, and the disassembly and assembly block has a telescopic hole inside.

[0008] Preferably, a connecting slider is slidably connected inside the telescopic hole. The end of the connecting slider away from the motor is connected to a limit clamp, and the limit clamp extends through the outside of the disassembly block and is inserted into the limit clamp hole.

[0009] Preferably, a locking spring is provided inside the connecting slider near the opening and closing motor, and the locking spring is elastically connected inside the telescopic hole. A splitting push block is connected to the outside of the connecting slider, and the splitting push block passes through the outside of the disassembly and assembly block and protrudes from the outside of the clamping seat.

[0010] Preferably, the clamping force adjustment assembly includes a support slider, an adjustment push plate, a clamping spring, and a threaded knob. The upper end of the clamping outer plate is provided with a telescopic groove, and the lower end of the clamping inner plate is connected to the support slider, which is slidably connected inside the telescopic groove.

[0011] Preferably, an adjusting push plate is slidably connected to the bottom of the inner cavity of the telescopic groove, and multiple clamping springs are provided between the supporting slider and the adjusting push plate. A threaded sleeve is connected to the center of the lower end of the clamping outer plate, and a threaded knob is threadedly connected inside the threaded sleeve.

[0012] Preferably, one end of the threaded knob protrudes outside the lower end of the clamping outer plate, and the other end is connected to a rotating chuck, which is rotatably connected to the center of the adjusting push plate.

[0013] Beneficial effects:

[0014] 1. The quick-release assembly of this utility model adopts a mechanical interlocking mechanism consisting of a disassembly and assembly slot, a disassembly and assembly block, a locking spring and a limit clamp head. Without tools, the entire wire clamp assembly can be quickly replaced and installed on the wire clamp base through a simple plugging and unplugging action, so as to adapt to wire harnesses of different diameters and improve the adaptability of production equipment.

[0015] 2. The clamping force adjustment component of this utility model drives the displacement of the push plate by rotating the threaded knob, thereby linearly compressing or releasing the clamping spring, realizing stepless adjustment of the pressure applied to the support slider and the clamping inner plate. This allows the clamping claws to accurately adjust the clamping force according to the softness and hardness of the wire harness material, avoiding damage to the cable insulation layer by the clamping claws or slippage due to insufficient force. While ensuring stable clamping, it perfectly protects the appearance and quality of the wire harness.

[0016] 3. The inner clamping plate of this utility model is made of polytetrafluoroethylene material and wrapped with an elastic rubber sleeve to form a composite clamping surface. This not only effectively prevents scratches on the wire harness surface caused by relative sliding during clamping, but also increases the contact area and buffers concentrated stress through elastic deformation, further eliminating the generation of clamping marks.

[0026] 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.

[0027] To achieve the above-mentioned utility model objectives, such as Figures 1-6 As shown, this utility model provides a wire clamp for a wire box workshop, including a wire clamping base 1, a wire clamping assembly, a quick-release assembly, and a clamping force adjustment assembly. The wire clamping assembly includes an opening and closing motor 3, a connecting rod 4, an outer clamping plate 5, and an inner clamping plate 6. The upper sides of both ends of the wire clamping base 1 are provided with opening and closing slots 2. An opening and closing motor 3 is installed inside the lower end of each of the two opening and closing slots 2. A connecting rod 4 is connected to the outside of each of the two opening and closing motors 3. The end of each connecting rod 4 away from the opening and closing motor 3 is connected to the outer clamping plate 5. An inner clamping plate 6 is provided on the upper side of each of the two outer clamping plates 5. A quick-release assembly is provided between the wire clamping assembly and the wire clamping base 1, allowing for quick installation and removal of the wire clamping assembly and the wire clamping base 1. A clamping force adjustment assembly is provided between each of the two outer clamping plates 5 and the two inner clamping plates 6, allowing for adjustment of the clamping force of the wire clamping assembly. During the clamping process of the positive and negative electrode cutting and riveting machine and the positive and negative electrode three-part machine in the wire box workshop, the clamping base 1 and the clamping assembly form a clamping claw. The clamping assembly is installed on the equipment through the clamping base 1, and the opening and closing motor 3 is electrically connected to the equipment through the wire harness. The corresponding clamping assembly can be quickly replaced through the quick-release assembly according to the thickness of the wire harness to ensure that the clamping assembly can stably clamp the wire harness. The clamping force can be adjusted through the clamping force adjustment assembly according to the softness and hardness of the wire harness to ensure that the clamping claw clamps the wire harness stably without clamping the wire harness and avoiding affecting the appearance and quality of the product. Then, the wire harness to be clamped is placed on the clamping base 1, and the opening and closing motors 3 on both sides are started. The opening and closing motors 3 drive the connecting rods 4 on both sides and the clamping outer plate 5 to rotate upward and move closer to each other, thereby clamping the wire harness.

[0028] The inner clamping plate 6 is made of polytetrafluoroethylene and is wrapped with an elastic rubber sleeve to reduce the clamping hardness of the jaws and further avoid damaging the wire harness. At the same time, the elastic clamping of the elastic rubber sleeve prevents the wire harness from loosening and improves the clamping stability.

[0029] Preferably, the quick-release assembly includes a disassembly / removal slot 7 and a disassembly / removal block 10. The lower side of the inner wall at both ends of the opening and closing rotating groove 2 is provided with a disassembly / removal slot 7. The two disassembly / removal slots 7 are provided with disassembly / removal blocks 10. The two disassembly / removal blocks 10 are respectively connected to the front and rear ends of the opening and closing motor 3 through the motor shaft. The wire clamping assembly can be quickly installed and removed by inserting and removing the disassembly / removal blocks 10 inside the disassembly / removal slots 7. This allows the wire clamping assembly to be replaced according to the thickness of the wire harness, and the clamps can stably clamp wire harnesses of different thicknesses, thereby improving the adaptability of the wire clamping assembly.

[0030] Preferably, the disassembly and assembly slot 7 has a connecting slot 8 at the end near the opening and closing motor 3, with the opening of the connecting slot 8 facing outwards, for connecting the motor shaft of the opening and closing motor 3 to the disassembly and assembly block 10. The disassembly and assembly slot 7 has a limit hole 9 at the end away from the opening and closing motor 3. The disassembly and assembly block 10 has a telescopic hole 11 inside, with a connecting slider 12 slidably connected inside the telescopic hole 11. The end of the connecting slider 12 away from the opening and closing motor 3 is connected to a limit head 13, which passes through the outside of the disassembly and assembly block 10 and is inserted into the limit hole 9. A locking spring 14 is provided inside the connecting slider 12 at the end near the opening and closing motor 3, and the locking spring 14 is elastically connected inside the telescopic hole 11. A splitting push block 15 is connected to the outside of the connecting slider 12, which passes through the outside of the disassembly and assembly block 10 and protrudes from the outside of the wire clamping seat 1. During the installation and disassembly of the wire clamping assembly, the opening and closing... The motor shaft between motor 3 and disassembly / assembly block 10 can slide inside the connecting groove 8, ensuring that disassembly / assembly block 10 can be smoothly inserted into disassembly / assembly slot 7, and that opening / closing motor 3 can be smoothly inserted into opening / closing rotating groove 2. When disassembly / assembly block 10 is inserted into disassembly / assembly slot 7, the limiting head 13 can be engaged with the limiting hole 9 through connecting slider 12 and locking spring 14, locking and limiting the disassembly / assembly slot 7 and disassembly / assembly block 10, ensuring that disassembly / assembly block 10 will not detach from the disassembly / assembly slot 7, and ensuring the stability of the gripper structure. When disassembly / assembly block 10 is pulled out from the disassembly / assembly slot 7, the connecting slider 12 is pulled inward by the splitting push block 15, and the limiting head 13 is pulled out from the limiting hole 9 through the connecting slider 12, releasing the lock between disassembly / assembly slot 7 and disassembly / assembly block 10, allowing disassembly / assembly block 10 to be smoothly pulled out from the disassembly / assembly slot 7, realizing the quick replacement of the wire clamping assembly.

[0031] Preferably, the clamping force adjustment assembly includes a support slider 17, an adjustment push plate 18, clamping springs 19, and a threaded knob 21. The upper end of the clamping outer plate 5 has a telescopic groove 16, and the lower end of the clamping inner plate 6 is connected to the support slider 17, which is slidably connected inside the telescopic groove 16. The bottom of the inner cavity of the telescopic groove 16 is slidably connected to the adjustment push plate 18. Multiple clamping springs 19 are arranged between the support slider 17 and the adjustment push plate 18. A threaded sleeve 20 is connected to the center of the lower end of the clamping outer plate 5, and a threaded knob 21 is threadedly connected inside the threaded sleeve 20. One end of the threaded knob 21 protrudes outside the lower end of the clamping outer plate 5, and the other end is connected to a rotating chuck, which rotates to connect to the center of the adjustment push plate 18. During the clamping force adjustment of the wire clamping assembly, the support slider 17 can be adjusted by multiple clamping springs... The clamping inner plate 6 is elastically connected inside the telescopic groove 16, so the clamping inner plate 6 can be elastically connected to the upper end of the clamping outer plate 5 through the support slider 17 and multiple clamping springs 19. When the clamping inner plates 6 on both sides rotate upward and move closer, the two clamping inner plates 6 can clamp the wire harness through the elastic force of multiple clamping springs 19, and the clamping force is positively correlated with the elastic force of multiple clamping springs 19. At this time, rotating the threaded knob 21, the threaded knob 21 drives the adjusting push plate 18 to move closer to or away from the support slider 17 through the threaded connection between the threaded knob 21 and the threaded sleeve 20, thereby increasing or decreasing the elastic force of multiple clamping springs 19 on the support slider 17, and thus increasing or decreasing the clamping force of the two clamping inner plates 6 on the wire harness, so that the wire clamping assembly can adjust the clamping force according to the softness and hardness of the wire harness, ensuring stable clamping of the wire harness without causing damage to the wire harness.

All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
