Description

Technical Field

[0001] This application relates to the field of through-hole positioning fixture technology, and in particular to through-hole positioning fixture for the outer layer of wire harness sleeve. Background Technology

[0002] The wire harness sleeve outer layer through-hole positioning fixture is a special tool used in the wire harness production process to accurately position the outer layer of the wire harness sleeve so that it can smoothly pass through specific holes.

[0003] Traditional devices use manual winding, which is inefficient, cannot meet batch production needs, and it is difficult to maintain a constant force manually, resulting in the winding area being either too loose or too tight.

[0004] Therefore, a new approach is needed to solve this problem. Utility Model Content

[0005] The purpose of this application is to provide a positioning fixture for the outer layer of the wire harness sleeve, which has the advantages of semi-automatic processing of products of different specifications. It solves the problems of low operating efficiency, inability to adapt to batch requirements, difficulty in maintaining constant force by hand, and easy occurrence of excessively loose or tight winding parts.

[0006] The wire harness sleeve outer layer through-hole positioning fixture provided in this application adopts the following technical solution: it includes a base, a motor is provided on the upper surface of the base, a connecting shaft is fixedly connected to the output end of the motor, a limit groove is formed on the outer surface of the connecting shaft, a connecting frame is slidably connected to the outer surface of the connecting shaft, the inner wall of the connecting frame is slidably connected to the limit groove, a threaded groove is formed on the outer surface of the connecting frame, a threaded post is threadedly connected to the inner wall of the threaded groove, a connecting head is fixedly connected to the end of the threaded post away from the connecting frame, and a plurality of long rods are fixedly connected to the outer surface of the connecting head, and a wire harness sleeve is sleeved on the outer surface of each long rod.

[0007] By adopting the above technical solution, the base serves as the basic support component of the entire tooling, used to fix and install other components, ensuring the stability of the tooling. The motor provides the power source, driving the connecting shaft to rotate through the output shaft, providing power support for subsequent positioning operations. After the motor starts, it drives the connecting shaft to rotate. Due to the sliding connection between the inner wall and the limiting groove of the connecting shaft, the connecting frame will rotate with the rotation of the connecting shaft. By rotating the threaded column and through the connection between the threaded column and the threaded groove, the long rod can be installed on the connecting frame. Then, the wire harness sleeve is put on the corresponding long rod, thereby realizing the position adjustment and positioning of the wire harness sleeve. The detachable connector makes it easy to replace the long rod of different specifications as needed to process products of different specifications.

[0008] Preferably, a tape roll is provided above the base, and a tape body is fixedly installed on the outer surface of the tape roll. The outer surface of the tape body is wound around the wire harness sleeve.

[0009] By adopting the above technical solution, the tape roll, as a storage and release component for the tape, is set above the base and can continuously supply tape. The tape roll is designed to be round for easy hand-holding. In use, the front end of the wire harness sleeve is fixed with tape, and then the motor is started. The two wire harness sleeves begin to rotate with the rotation of the two long rods, moving the tape backward from the fixed front end. As the tape rotates, it will tightly wrap around the outside of the two wire harness sleeves. When the specified position is reached and the tape is tightly wrapped, the motor rotation is stopped manually.

[0010] Preferably, the inner wall of the base is threaded with a fixing bolt, and the outer surface of the fixing bolt is inserted into the motor.

[0011] By adopting the above technical solution, the inner wall of the base is connected to the fixing bolts by threads, and the outer surface of the fixing bolts is then inserted into the motor, forming a dual fixing structure of thread locking and insertion positioning. This can effectively offset the vibration of the motor during operation and prevent the motor from shifting, which would cause deviations in subsequent positioning accuracy. The threaded fixing bolts can be flexibly disassembled. When the motor malfunctions and needs to be repaired or replaced, the motor can be removed simply by unscrewing the fixing bolts, without damaging the base or the motor itself, thus improving maintenance convenience.

[0012] Preferably, an elastic clamp is fixedly connected to the outer surface of the connecting frame, and an anti-slip woven sleeve is engaged with the inner wall of the elastic clamp.

[0013] By adopting the above technical solution, the elastic clamp is fixed on the outer surface of the connecting frame and serves as the direct clamping component for the anti-slip braided sleeve. The characteristics of the elastic clamp give it self-adaptive clamping capability. It can clamp the sleeve with its own elasticity to prevent loosening, and it can also adapt to anti-slip braided sleeves of different diameters, eliminating the need for frequent clamp replacements. Its snap-fit ​​design facilitates quick loading and unloading of the sleeve, improving operational efficiency. During use, two long rods are inserted into two wire harness sleeves respectively. After the wire harness sleeves are passed through the anti-slip braided sleeve, the motor is started to generate rotational force, which spirals the wire harness sleeves into the anti-slip braided sleeve.

[0014] Preferably, a sleeve is fitted onto the outer surface of the connecting frame, and the sleeve is fitted onto the anti-slip woven sleeve.

[0015] By adopting the above technical solution, the sleeve, when fitted onto the anti-slip braided sleeve, provides additional fastening, preventing loosening or displacement during tooling operation. Combined with the elastic clamp, it more stably holds the anti-slip braided sleeve, ensuring accuracy during operations such as hole positioning. The sleeve provides a precise positioning reference for the anti-slip braided sleeve, helping it to accurately occupy the predetermined position for subsequent cooperation with other components. During hole operations, it guides the wire harness sleeve to accurately pass through the corresponding hole, improving processing accuracy and consistency.

[0016] Preferably, a connecting column is fixedly connected to the outer surface of the connecting frame, an insert rod is slidably connected to the inner wall of the connecting column, and a pull block is fixedly connected to the end of the insert rod away from the connecting column.

[0017] By adopting the above technical solution, the connecting column serves as the sliding carrier of the insertion rod, fixed on the outer surface of the connecting frame, providing a stable installation foundation and sliding guide for the insertion rod, and enabling manual operation through the pull block.

[0018] Preferably, the inner wall of the limiting groove is provided with a slot, and the inner wall of the slot is inserted into the rod.

[0019] By adopting the above technical solution, the slot is opened on the inner wall of the limiting groove of the connecting shaft, serving as a precise positioning interface for the plug rod. It cooperates with the plug rod to mechanically lock the connecting frame and the connecting shaft, forming a rigid fixation.

[0020] Preferably, a spring is fitted onto the outer surface of the insertion rod, with one end of the spring near the connecting frame fixedly connected to the insertion rod and the other end fixedly connected to the connecting post.

[0021] By adopting the above technical solution, the two ends of the spring are fixed to the insertion rod and the connecting post respectively. Under natural conditions, it is in a slightly compressed state and will continuously apply a spring force to the insertion rod to push it into the slot. When the pull block is pulled to unlock, the spring will automatically push the insertion rod into the nearest slot when the pull block is released, without the need for manual alignment or pushing, which greatly improves the operating efficiency.

[0022] In summary, this application includes at least one of the following beneficial technical effects: This wire harness sleeve outer layer through-hole positioning fixture, by setting up components such as a motor, connecting shaft, limiting groove, connecting frame, threaded groove, threaded post, connector, long rod, and wire harness sleeve body, allows empty wire harness sleeve bodies to be fitted into the corresponding long rods. Then, the motor is started to drive the long rods to rotate around the central axis of the connecting shaft. By setting up detachable connectors and installing connectors with long rods of different specifications to the connecting frame, products of different specifications can be processed. Thus, this device can achieve the effect of semi-automatic processing of products of different specifications through the motor and detachable connectors. Attached Figure Description

[0027] The base 1 serves as the basic support component of the entire tooling, used to fix and install other components, ensuring the stability of the tooling. The motor 2 provides the power source, driving the connecting shaft 4 to rotate through the output shaft, providing power support for subsequent positioning operations. After the motor 2 starts, it drives the connecting shaft 4 to rotate. The connecting frame 7, due to the sliding connection between its inner wall and the limiting groove 5 of the connecting shaft 4, will rotate with the rotation of the connecting shaft 4. By rotating the threaded column 15 and connecting the threaded column 15 with the threaded groove 13, the long rod 17 can be installed on the connecting frame 7. Then, the wire harness sleeve 21 is fitted onto the corresponding long rod 17, thereby realizing the position adjustment and positioning of the wire harness sleeve 21. The detachable connector 16 facilitates the replacement of long rods 17 of different specifications as needed to process products of different specifications.

[0028] Example 2: Wiring harness outer layer through-hole positioning fixture, please refer to Figure 1 , Figure 2 A tape roll 19 is provided above the base 1. A tape body 20 is fixedly installed on the outer surface of the tape roll 19. The outer surface of the tape body 20 is wrapped around the wire harness sleeve 21. The tape roll 19 serves as a storage and release component for the tape body 20. It is located above the base 1 and can continuously provide the tape body 20. The tape roll 19 is designed to be round for easy hand-holding. When in use, the front end of the wire harness sleeve 21 is fixed with tape. Then the motor 2 is started, and the two wire harness sleeves 21 begin to rotate with the rotation of the two long rods 17, moving the tape backward from the fixed front end. As the tape rotates, it will be tightly wrapped around the outside of the two wire harness sleeves 21. When the specified position is reached and the tape is tightly wrapped, the motor 2 is manually stopped.

[0029] Please see Figure 1 , Figure 2 , Figure 3 The inner wall of the base 1 is threaded with a fixing bolt 3. The outer surface of the fixing bolt 3 is inserted into the motor 2. The inner wall of the base 1 is connected to the fixing bolt 3 by threads, and the outer surface of the fixing bolt 3 is then inserted into the motor 2, forming a dual fixing structure of threaded locking and insertion positioning. This can effectively offset the vibration of the motor 2 during operation and prevent the motor 2 from shifting, which would cause subsequent positioning accuracy deviations. The threaded fixing bolt 3 can be flexibly disassembled. When the motor 2 malfunctions and needs to be repaired or replaced, the motor 2 can be removed simply by unscrewing the fixing bolt 3, without damaging the base 1 or the motor 2 itself, thus improving maintenance convenience.

[0030] Please see Figure 3 , Figure 4 , Figure 5An elastic clamp 12 is fixedly connected to the outer surface of the connecting frame 7. An anti-slip braided sleeve 14 is snapped into the inner wall of the elastic clamp 12. The elastic clamp 12 is fixed to the outer surface of the connecting frame 7 and serves as the direct clamping component for the anti-slip braided sleeve 14. The characteristics of the elastic clamp 12 give it self-adaptive clamping capability. It can clamp the sleeve with its own elasticity to prevent loosening and can adapt to anti-slip braided sleeves of different diameters without frequent clamp replacement. Its snap-fit ​​design facilitates quick loading and unloading of the sleeve and improves operating efficiency. During use, two long rods 17 are respectively inserted into two wire harness sleeves 21. The wire harness sleeves 21 are then passed through the anti-slip braided sleeve 14. The motor 2 is started to generate rotational force, which spirals the wire harness sleeves 21 into the anti-slip braided sleeve 14.

[0031] Please see Figure 1 , Figure 2 , Figure 3 A sleeve 18 is fitted onto the outer surface of the connecting frame 7. The sleeve 18 is fitted onto the anti-slip braided sleeve 14. The sleeve 18 provides additional fastening for the anti-slip braided sleeve 14, preventing it from loosening or shifting during tooling operation. Together with the elastic clamp 12, it can more stably hold the anti-slip braided sleeve 14, ensuring its accuracy during operations such as hole positioning. The sleeve 18 provides a precise positioning reference for the anti-slip braided sleeve 14, helping it to be accurately positioned in the predetermined location for subsequent cooperation with other components. During hole operations, it can guide the wire harness sleeve 21 to accurately pass through the corresponding hole, improving the processing accuracy and consistency.

[0033] Please see Figure 5 The inner wall of the limiting groove 5 is provided with a slot 6, and the inner wall of the slot 6 is inserted into the insertion rod 9. The slot 6 is opened on the inner wall of the limiting groove 5 of the connecting shaft 4, serving as a precise positioning interface for the insertion rod 9. In conjunction with the insertion of the insertion rod 9, the connecting frame 7 and the connecting shaft 4 are mechanically locked together to form a rigid fixation.

Both ends of the spring 11 are fixed to the insertion rod 9 and the connecting post 8 respectively. In its natural state, it is in a slightly compressed state and will continuously apply a spring force to the insertion rod 9 to push it toward the slot 6. When the pull block 10 is pulled to unlock it, and the pull block 10 is released, the spring 11 will automatically push the insertion rod 9 into the nearest slot 6 without the need for manual alignment or pushing, which greatly improves the efficiency of operation.

[0035] The implementation principle of this application embodiment is as follows: First, take out the connectors 16 of different specifications as needed, then use the fixing bolts 3 to fix the motor 2 on the base 1 and install it with the connecting bracket 7. During this process, by rotating the connector 16, the threaded post 15 is connected to the threaded groove 13, so that the long rods 17 of different specifications can be installed. Then, pull the pull block 10 to make it drive the insertion rod 9 to slide horizontally along the connecting post 8. At this time, the spring 11 will be compressed. Then, the connecting bracket 7 is sleeved along the connecting shaft 4, and the connecting bracket 7 will slide horizontally along the limiting groove 5 until the insertion rod... With slot 9 and slot 6 on the same central axis, release the pull block 10. The spring 11 will push the plug rod 9 into slot 6 under its rebound force, thus completing the quick installation of the connector 7. Then, put the wire harness sleeve 21 on the corresponding long rod 17, and then fix the front end of the wire harness sleeve 21 with tape. Start the motor 2, and the wire harness sleeve 21 will start to rotate with the rotation of the two long rods 17. Move the tape from the fixed front end backward. As the rotation occurs, the tape will be tightly wrapped around the outside of the two wire harness sleeves. When the specified position is reached and the tape is tightly wrapped, manually stop the rotation of the motor 2.
