Description

Technical Field

[0001] This utility model relates to the field of automotive wiring harness production technology, specifically a stranding machine for automotive wiring harness production. Background Technology

[0002] Automotive wiring harnesses are the main network of automotive circuits; without wiring harnesses, there would be no automotive circuits. A wiring harness is an assembly that connects circuits by crimping copper contact terminals (connectors) to wires and cables, then molding an insulator or adding an outer metal shell, and finally bundling the wires together.

[0003] Existing wire harness production stranding machines require specific replacements due to differences in wire harness diameter or number of strands during actual use. However, the replacement speed is slow, resulting in long downtime. Additionally, the tail clamp can slip during use, requiring periodic lubrication. However, lubrication requires disassembling the clamp, which is extremely inconvenient. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a stranding machine for automotive wiring harness production, which has the advantages of easy replacement of stranding heads and easy addition of lubricant, thus solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a stranding machine for automotive wiring harness production, comprising a base, a drive device and a sliding rail fixedly mounted on the top of the base, a drive disc fixedly mounted on the output shaft of the drive device, a stranding head provided on the outer wall of the drive disc, a sliding clamp block slidably connected to the outer wall of the sliding rail, an oil storage chamber fixedly mounted on the outer wall of the sliding clamp block, a rubber hose movably sleeved on the outer wall of the oil storage chamber, a piston disc slidably connected to the inner wall of the oil storage chamber, a threaded column rotatably connected to the outer wall of the piston disc, a limit rod fixedly mounted on the outer wall of the piston disc, a fixing plate slidably connected to the inner wall of the sliding clamp block, a limit column and a connecting rod fixedly mounted on the outer wall of the fixing plate, a cross plate fixedly mounted on the outer wall of the connecting rod, a spring provided on the inner wall of the sliding clamp block, a bidirectional lead screw rotatably connected to the inner wall of the drive disc, a sliding plate slidably connected to the inner wall of the drive disc, a connecting plate fixedly mounted on the outer wall of the sliding plate, a clamping plate fixedly mounted on the outer wall of the connecting plate, an insert plate fixedly mounted on the outer wall of the clamping plate, and a fixing groove provided on the outer wall of the stranding head.

[0006] As a preferred technical solution of this utility model: the threaded column penetrates the outer wall of the oil storage cavity, and the threaded column and the oil storage cavity are threadedly connected, and the outer wall of the piston disc fits against the inner wall of the oil storage cavity.

[0007] As a preferred technical solution of this utility model: the number of the limiting rods is two, and the two limiting rods are symmetrically arranged on the outer wall of the piston disc, and the two limiting rods penetrate the outer wall of the oil storage chamber.

[0008] As a preferred technical solution of this utility model: the shape of the fixing plate is adapted to the inner wall shape of the sliding clamp, and the fixing plate is in contact with the inner wall of the sliding clamp.

[0009] As a preferred technical solution of this utility model: the bidirectional lead screw passes through the sliding plate, and the bidirectional lead screw and the sliding plate are connected by threads.

[0010] As a preferred technical solution of this utility model: the shape of the insert plate is adapted to the shape of the fixing groove, and the positions of the insert plate and the fixing groove correspond to each other.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This stranding machine for automotive wiring harness production places the stranded head outside the drive disc, aligning the fixing groove on the outside of the stranded head with the position of the insert plate. By rotating the bidirectional lead screw, the bidirectional lead screw drives two sliding plates to move, which in turn moves two connecting plates, clamping plates, and insert plates towards the center. This causes the insert plates on both sides to enter the fixing groove, thus fixing the fixing groove and securing the stranded head, making the replacement of the stranded head more convenient.

[0013] 2. This stranding machine for automotive wiring harness production rotates a threaded column, causing the threaded column to move against the inner wall of the oil reservoir through a threaded connection. This movement causes the oil reservoir to move a piston disc, which then moves against the inner wall of the oil reservoir, squeezing the lubricating oil inside the reservoir. The fixed plate is then squeezed into the sliding clamp, causing it to separate from the inner wall of the sliding clamp. This eliminates the sealing effect of the sliding clamp, allowing the lubricating fluid inside the oil reservoir to be introduced into the sliding clamp. Alternatively, a rubber hose can be installed outside the oil reservoir, allowing the piston disc to draw lubricating fluid into the reservoir. Attached Figure Description

[0021] 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.

[0022] Please see Figure 1 - Figure 6 A stranding machine for automotive wiring harness production includes a base 1. A drive unit 2 and a sliding rail 5 are fixedly mounted on the top of the base 1. A drive disc 3 is fixedly mounted on the output shaft of the drive unit 2. A stranding head 4 is provided on the outer wall of the drive disc 3. A sliding clamp 6 is slidably connected to the outer wall of the sliding rail 5. An oil storage chamber 7 is fixedly mounted on the outer wall of the sliding clamp 6. A rubber hose 8 is movably sleeved on the outer wall of the oil storage chamber 7. A piston disc 9 is slidably connected to the inner wall of the oil storage chamber 7. A threaded column 10 is rotatably connected to the outer wall of the piston disc 9. A limit rod 11 is fixedly mounted on the outer wall of the piston disc 9. A fixed plate 12 is slidably connected to the inner wall of the movable clamping block 6. A limit post 13 and a connecting rod 14 are fixedly installed on the outer wall of the fixed plate 12. A horizontal plate 15 is fixedly installed on the outer wall of the connecting rod 14. A spring 16 is provided on the inner wall of the sliding clamping block 6. A two-way lead screw 17 is rotatably connected to the inner wall of the drive disc 3. A sliding plate 18 is slidably connected to the inner wall of the drive disc 3. A connecting plate 19 is fixedly installed on the outer wall of the sliding plate 18. A clamping plate 20 is fixedly installed on the outer wall of the connecting plate 19. An insert plate 21 is fixedly installed on the outer wall of the clamping plate 20. A fixing groove 22 is opened on the outer wall of the auger 4.

[0023] In the above structure, the sliding plate 18 is attached to the inner wall of the drive disk 3, so that the sliding plate 18 is limited by the inner wall of the drive disk 3 when it moves, thereby limiting the sliding plate 18 when it moves, and thus preventing the sliding plate 18 from tilting when it moves.

[0024] In a preferred embodiment: the threaded post 10 penetrates the outer wall of the oil storage cavity 7, and the threaded post 10 and the oil storage cavity 7 are threadedly connected, and the outer wall of the piston disc 9 fits against the inner wall of the oil storage cavity 7.

[0025] In the above structure, by rotating the threaded column 10, the threaded column 10 moves within the inner wall of the oil reservoir 7 through its threaded connection with the oil reservoir 7. This causes the oil reservoir 7 to move the piston disc 9, which in turn moves by adhering to the inner wall of the oil reservoir 7. Consequently, the piston disc 9 squeezes or draws the lubricating oil inside the oil reservoir 7.

[0026] In a preferred embodiment, there are two limiting rods 11, and the two limiting rods 11 are symmetrically arranged on the outer wall of the piston disc 9, and the two limiting rods 11 penetrate the outer wall of the oil storage chamber 7.

[0027] In the above structure, the outer wall of the oil storage chamber 7 is penetrated by two limiting rods 11, so that the oil storage chamber 7 limits the two limiting rods 11, thereby limiting the two limiting rods 11 when they move, thus limiting the piston disc 9, so that the piston disc 9 will not tilt when it moves.

[0028] In a preferred embodiment, the shape of the fixing plate 12 is adapted to the inner wall shape of the sliding clamp 6, and the fixing plate 12 is in contact with the inner wall of the sliding clamp 6.

[0029] In the above structure, the fixed plate 12 is squeezed and moves into the interior of the sliding clamp 6, thereby separating the fixed plate 12 from the inner wall of the sliding clamp 6, thereby eliminating the sealing effect of the sliding clamp 6, and allowing the lubricant inside the oil storage cavity 7 to be input into the interior of the sliding clamp 6.

[0030] In a preferred embodiment, the bidirectional lead screw 17 passes through the sliding plate 18, and the bidirectional lead screw 17 and the sliding plate 18 are threadedly connected.

[0031] In the above structure, by rotating the bidirectional lead screw 17, the bidirectional lead screw 17 drives the sliding plate 18 to move through the threaded connection between the sliding plate 18 and the sliding plate 18, which in turn drives the connecting plate 19 to move, and the connecting plate 19 drives the clamping plate 20 and the insert plate 21 to move.

[0032] In a preferred embodiment, the shape of the insert plate 21 is adapted to the shape of the fixing groove 22, and the positions of the insert plate 21 and the fixing groove 22 correspond.

[0033] In the above structure, the insert plate 21 enters the interior of the fixing groove 22, thereby fixing the position of the fixing groove 22, and thus fixing the auger 4 through the fixing groove 22.

[0034] Working Principle: When using the equipment, the appropriate twisted head 4 needs to be selected based on the number and thickness of the wires used. The twisted head 4 is placed outside the drive disc 3, with the fixing groove 22 on the outside of the twisted head 4 corresponding to the position of the insert plate 21. Rotating the bidirectional lead screw 17 causes the two sliding plates 18 to move through their threaded connection. This, in turn, causes the two sliding plates 18 to move the two connecting plates 19, clamping plates 20, and insert plates 21 towards the center. The insert plates 21 then enter the fixing groove 22, fixing it in place and thus securing the twisted head 4. The wires are then fixed using the sliding clamp 6, and the end of the wire furthest from the sliding clamp 6 is connected to the twisted head 4. Activating the drive device 2 then rotates the drive disc 3. The drive disc 3 drives the winch head 4 to rotate, thereby performing the winding operation. When it is necessary to input lubricant into the sliding clamp 6, the threaded column 10 is rotated, causing the threaded column 10 to move through the threaded connection with the oil reservoir 7 and onto the inner wall of the oil reservoir 7. This causes the oil reservoir 7 to drive the piston disc 9 to move, causing the piston disc 9 to move by adhering to the inner wall of the oil reservoir 7. This causes the piston disc 9 to squeeze the lubricant inside the oil reservoir 7, and the fixed plate 12 to move into the sliding clamp 6 under pressure. This causes the fixed plate 12 to separate from the inner wall of the sliding clamp 6, thereby eliminating the sealing effect of the sliding clamp 6. This allows the lubricant inside the oil reservoir 7 to be input into the sliding clamp 6. This can be achieved by installing a rubber hose 8 on the outside of the oil reservoir 7, and then drawing the lubricant into the oil reservoir 7 through the movement of the piston disc 9.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
