Description

Technical Field

[0001] This application relates to the field of wire harness winding device technology, and in particular to a fast clamping mechanism. Background Technology

[0002] A wire reel is a tool or device used for winding and storing linear materials such as wires, cables, and ropes, and it has wide applications in various fields. For example... Figure 1 The coil shown primarily consists of a spool 100, side plates 200, and a central shaft. The spool, typically cylindrical, is the core component and is used to wind wires or cables. The spool can be made of plastic, metal, or wood, depending on the specific application and environment. The side plates connect to both ends of the spool, providing fixation and support while preventing wires or cables from slipping off. The shape and size of the side plates can be designed according to the coil's intended use and specifications. The central shaft runs through the center of the spool and side plates, supporting the entire coil and allowing it to rotate freely.

[0003] When the wire harness is wound and stored using a wire spool, the spool needs to be positioned first. One side of the spool is driven by a motor, while the other side requires a clamping mechanism for contact. Existing clamping mechanisms are mainly handwheel and screw structures. The screw is driven by manually turning the handwheel. The nut that mates with the screw is confined within a fixed guide rail or groove and cannot rotate with the screw. It can only move linearly along the axis of the screw, causing the contact block connected to the nut to translate and gradually move closer to the spool until it is pressed against the side plate of the spool.

[0004] After the spool finishes winding, it needs to be removed. Since the linear movement of the lead screw depends on the rotation of the handwheel, the operator needs to rotate the handwheel many times to control the abutment block away from the spool. This operation is quite troublesome and needs to be improved. Utility Model Content

[0005] To facilitate the clamping and loosening of the wire reel and improve ease of use, this application provides a quick-clamping mechanism.

[0006] The rapid clamping mechanism provided in this application adopts the following technical solution:

[0007] A kind of quick chuck mechanism, including sleeve, outer tube, limiting component, screw rod, hand wheel and abutment block, the sleeve is hollowly arranged, the outer tube is sleeved in the sleeve, several limiting grooves are opened in the side wall of the outer tube, each limiting groove is spaced apart along the length direction of the outer tube;The limiting component is located on the sleeve, and is clamped in the limiting groove;The screw rod is located in the outer tube, the hand wheel is rotatably connected to one end of the outer tube, and is connected with the screw rod;The abutment block is rotatably connected to the end of the screw rod away from the hand wheel, the screw rod is used to control the linear movement of the abutment block, and the abutment block is used to abut on the side plate of the reel.

[0008] By adopting the above technical scheme, when the reel needs to be clamped, the staff first applies external force to the outer tube and controls the movement of the outer tube, the outer tube and the sleeve will move relatively, so that the entire outer tube quickly approaches the reel. Then the limiting component is clamped in the limiting groove to limit the movement of the outer tube. Then the staff manually rotates the hand wheel, and the abutment block connected with the screw rod produces translational motion, so that the abutment block further presses on the side plate of the reel.

[0009] When the reel winding is completed, the connection between the limiting component and the limiting groove can be released, so that the outer tube and the sleeve can move relatively, and then external force is applied to the outer tube, so that the entire outer tube and the abutment block quickly move away from the reel, completing the disassembly of the reel. Unlike the prior art, the hand wheel does not need to be rotated multiple times, improving the convenience of production.

[0010] Preferably, the limiting component includes a fixed block, a latch and a limiting block, a through hole is formed through the sleeve, the fixed block is provided in the through hole, one end of the latch passes through the fixed block and is connected with the limiting block, and the limiting block is clamped in the limiting groove. A clearance groove is formed in the fixed block for the limiting block to pass through.

[0011] By adopting the above technical scheme, the sleeve and the outer tube are limited by the cooperation of the limiting block and the limiting groove. When the movement of the outer tube needs to be controlled, the staff can apply a pulling force to the latch to make the limiting block disengage from the limiting groove. At this time, part of the limiting block will enter the clearance groove. When the position of the outer tube is adjusted, the limiting block is clamped in the corresponding limiting groove.

[0012] Preferably, the end of the latch away from the limiting block is provided with a disc.

[0013] By adopting the above technical scheme, the disc can increase the area of contact between the staff and the latch, so as to better apply external force to the latch.

[0014] Preferably, the fixed block is detachably connected to the sleeve by a fastener.

[0015] By adopting the technical scheme, when the whole limiting assembly is damaged, the fixed block can be disassembled from the sleeve and then replaced, thereby reducing the maintenance cost.

[0016] Preferably, the limiting assembly further comprises a spring, the spring is sleeved on the bolt, and two ends of the spring are connected with the limiting block and the fixed block respectively, when the limiting block moves away from the limiting groove, the spring is compressed.

[0017] By adopting the technical scheme, when the staff controls the bolt to be pulled out of the limiting groove, the limiting block moves relative to the fixed block, at this time, the spring is elastically deformed and compressed. When the action force of the bolt is removed, under the elastic restoring force of the spring, the limiting block can be clamped in the limiting groove, thereby improving the stability of the limiting block falling in the limiting groove.

[0018] Preferably, the abutting block is rotatably connected to the screw rod through a ball bearing.

[0019] By adopting the technical scheme, when one side of the wire reel abuts against the output shaft of the driving motor and the other side abuts against the abutting block, the driving motor is controlled to rotate the wire reel, and the existence of the ball bearing can realize the relative rotation of the abutting block and the screw rod, that is, the abutting block rotates synchronously with the wire reel, thereby completing the winding and rolling of the wire harness.

[0020] Preferably, the abutting block is detachably connected to the ball bearing through a bolt.

[0021] By adopting the technical scheme, when the abutting block is damaged, the abutting block can be disassembled and replaced. Or when different specifications of abutting blocks are needed, the corresponding abutting block can be replaced to abut against the wire reel.

[0022] Preferably, a plurality of friction lines are arranged on the handle of the hand wheel.

[0023] By adopting the technical scheme, the friction lines can increase the static friction force between the staff and the handle, thereby better exerting the external force on the hand wheel.

[0024] In summary, the present application has at least one of the following beneficial technical effects:

[0025] (1) By arranging the outer cylinder and the limiting assembly, when the wire reel is rolled up, the connection between the limiting assembly and the limiting groove on the outer cylinder can be released, so that the outer cylinder and the sleeve can move relatively, and then an external force is applied to the outer cylinder, so that the whole outer cylinder and the abutting block quickly move away from the wire reel.

[0026] (2) By arranging a disc at the end of the bolt, the disc can increase the contact area between the staff and the bolt, thereby better exerting the force on the bolt.

[0027] (3) By setting the fixed block can be detachably connected on the sleeve, when the limiting component is damaged, the limiting component can be replaced, reducing maintenance cost. BRIEF DESCRIPTION OF DRAWINGS

[0040] The embodiments of the present application disclose a quick chuck mechanism. Referring to Figures 2-3 , the chuck mechanism comprises a sleeve 1, an outer cylinder 2, a limiting assembly 3, a lead screw 4, a hand wheel 5 and an abutting block 6. The sleeve 1 is cylindrical and hollow. The outer cylinder 2 is also cylindrical, and the outer cylinder 2 is movably arranged in the sleeve 1. A plurality of limiting grooves 9 are formed on the side wall of the outer cylinder 2, each limiting groove 9 is on the same straight line and is distributed along the length direction of the outer cylinder 2. The limiting assembly 3 is installed on the sleeve 1 and is used for clamping in the limiting groove 9, so as to limit the relative movement of the outer cylinder 2 and the sleeve 1. The lead screw 4 is installed in the inner part of the outer cylinder 2, the hand wheel 5 is rotatably connected to one end of the outer cylinder 2 and is connected with the lead screw 4, and the hand wheel 5 is used to drive the lead screw 4 to rotate. The abutting block 6 is located on the end of the lead screw 4 away from the hand wheel 5, and is rotatably connected to the nut matched with the lead screw 4 through the ball bearing 8. The lead screw 4 is used to drive the abutting block 6 to do linear motion, and the abutting block 6 is used to abut on the side plate of the chuck plate. In some embodiments, the abutting block 6 is locked on the ball bearing 8 through bolts or screws, and the detachable connection of the abutting block 6 and the ball bearing 8 is realized by the screwing force.

[0041] In combination with Figures 4-6Specifically, the limiting assembly 3 comprises a fixed block 31, a bolt 32 and a limiting block 33. A through hole is formed through the sleeve 1, and the through hole is communicated with the limiting groove 9. The fixed block 31 is installed at the through hole, one end of the bolt 32 penetrates through the fixed block 31 and is connected with the limiting block 33, and the limiting block 33 is clamped in the limiting groove 9. A clearance groove 10 is formed in the fixed block 31, and the clearance groove 10 is used for allowing the limiting block 33 to penetrate through. The end of the bolt 32 away from the limiting block 33 is fixedly connected with a disc 7, and the diameter of the disc 7 is greater than the diameter of the bolt 32. The disc 7 can increase the contact area between the worker and the bolt 32, so that the external force can be better applied to the bolt 32. In the embodiment, the fixed block 31 is detachably connected to the sleeve 1 by a fastener, the fastener is a fastening bolt, and the fixed block 31 and the sleeve 1 are fixed by screwing. When the entire limiting assembly 3 is damaged, the fixed block 31 can be detached from the sleeve 1, and then replaced, thereby reducing the maintenance cost.

[0042] When it is necessary to clamp the wire coil, the worker first applies an external force to the outer cylinder 2 and controls the movement of the outer cylinder 2, so that the outer cylinder 2 and the sleeve 1 move relatively, so that the entire outer cylinder 2 quickly approaches the wire coil. Then the limiting block 33 is clamped in the limiting groove 9 to limit the movement of the outer cylinder 2. Then the worker manually rotates the hand wheel 5, and the abutting block 6 connected with the screw rod 4 generates a translational motion, so that the abutting block 6 is further pressed on the side plate of the wire coil.

[0043] When the winding of the wire coil is completed, the connection between the limiting block 33 and the limiting groove 9 can be released, so that the outer cylinder 2 and the sleeve 1 can move relatively, and then an external force is applied to the outer cylinder 2, so that the entire outer cylinder 2 and the abutting block 6 quickly move away from the wire coil, completing the disassembly of the wire coil, without the need to rotate the hand wheel 5 multiple times as in the prior art, thereby improving the convenience of production.

[0044] The limiting assembly 3 further comprises a spring 34, the spring 34 is sleeved on the bolt 32, and the two ends of the spring 34 are connected with the limiting block 33 and the fixed block 31 respectively. When the worker controls the bolt 32 to be pulled out of the limiting groove 9, the limiting block 33 moves relative to the fixed block 31, at this time the spring 34 is elastically deformed and compressed. When the action force of the bolt 32 is removed, the limiting block 33 can be clamped in the limiting groove 9 under the elastic restoring force of the spring 34, thereby improving the stability of the limiting block 33 falling in the limiting groove 9. In addition, a plurality of friction lines are arranged on the handle of the hand wheel 5. The friction lines can increase the static friction force between the worker and the handle, so that the external force can be better applied to the hand wheel 5.

[0045] The implementation principle of the quick chuck mechanism in the embodiment of the application is as follows: when the wire coil needs to be clamped, the worker first applies an external force to the outer cylinder 2 and controls the outer cylinder 2 to move, so that the outer cylinder 2 and the sleeve 1 are relatively displaced, and then the whole outer cylinder 2 quickly approaches the wire coil. Then, the limiting block 33 is clamped in the limiting groove 9, so as to limit the movement of the outer cylinder 2. Then, the worker manually rotates the hand wheel 5, and the abutting block 6 connected with the screw rod 4 immediately generates a translational motion, so that the abutting block 6 can be further tightly pressed on the side plate of the wire coil.

[0046] When one side of the wire coil abuts against the output shaft of the driving motor and the other side abuts against the abutting block 6, the driving motor is operated to control the wire coil to rotate. Since the ball bearing 8 exists, the relative rotation of the abutting block 6 and the screw rod 4 can be realized, that is, the abutting block 6 rotates synchronously with the wire coil, so that the winding and winding of the wire harness are completed.

[0047] After the winding of the wire coil is completed, the connection between the limiting block 33 and the limiting groove 9 can be released, so that the outer cylinder 2 and the sleeve 1 can be relatively moved again. Then, the external force is applied to the outer cylinder 2, so that the whole outer cylinder 2 and the abutting block 6 quickly move away from the wire coil, so that the dismounting operation of the wire coil is completed. Compared with the method of rotating the hand wheel 5 many times in the prior art, the method significantly improves the convenience of the production process.

[0048] The above are the preferred embodiments of the application, and do not limit the protection scope of the application, so that: any equivalent changes made according to the structure, shape, principle of the application should be covered in the protection scope of the application.
