Description

Technical Field

[0001] This utility model relates to the field of clamping technology, specifically to a universal clamp for a horizontal wire reel used in a wire take-up machine. Background Technology

[0002] A spool is a disc-shaped structure used with a take-up machine, where the take-up machine winds the yarn bundle onto an empty spool. Spools come in various sizes. A spool clamp is a device that holds and moves the spool, for example, by moving an empty spool to the take-up station or clamping and sending a full spool from the take-up station. However, existing spool clamps only have a gripping function. Before removing the spool, a manual operator must first use a tool to unscrew the nut on the spool shaft several times to remove it, and then use the spool clamp to remove the spool. After installing an empty spool, the nut must be turned several more times to lock the spool in place. This process is time-consuming, labor-intensive, and easily causes fatigue. Furthermore, excessive manual intervention prolongs the overall spool changing cycle, resulting in relatively low work efficiency and making it difficult to meet the continuous operation requirements of high-speed take-up machines. Utility Model Content

[0003] To address the aforementioned shortcomings, the purpose of this utility model is to provide a horizontal universal clamp for wire reels with a reasonable structural design that can simultaneously lock and unlock the nuts on the reel shaft while clamping and transporting the reel.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0005] A horizontal wire reel universal clamp includes at least three jaws, a rotating coil, a clamping seat, a clamping motor, a mounting base, a nut sleeve, a nut shaft, and a nut motor. The rotating coil is rotatably mounted within the clamping seat. The mounting base has several radial grooves symmetrically arranged around its center on its front side. The clamping seat is movably mounted on the radial grooves and has threads that mesh with the rotating coil. When the rotating coil rotates, it can drive several clamping seats to move closer or further away from the center synchronously. The jaws are mounted on the clamping seat, and the clamping motor is mounted on the clamping seat and can drive the rotating coil to rotate. The nut shaft is rotatably mounted at the center of the mounting base, the nut sleeve is mounted at the front end of the nut shaft, and the nut motor is mounted on the clamping seat and can drive the nut shaft to rotate.

[0006] As a preferred embodiment of this utility model, a shaft cylinder is provided at the center of the mounting base, and an outer bearing is sleeved on the outer wall of the shaft cylinder. The rotating coil is sleeved on the outer bearing, which has a good assembly effect, reduces the frictional resistance of the rotating coil, and makes the rotating coil run smoothly.

[0007] In a preferred embodiment of this utility model, a front inner bearing is provided at the front part of the shaft cylinder, and a rear inner bearing is provided at the rear part. The nut shaft is clearance-fitted with the inner ring of the front inner bearing, allowing the nut shaft to slide axially. A step is provided on the nut shaft at the position between the front and rear inner bearings. A flat part is provided at the tail of the nut shaft. An axial sleeve for axial movement of the nut shaft is fitted on the tail of the nut shaft. The axial sleeve is interference-fitted with the inner ring of the rear inner bearing. A spring is fitted on the nut shaft. The front end of the spring abuts against the step, and the tail end abuts against the axial sleeve, forming an axial elastic buffer, allowing the nut shaft to slide axially.

[0008] In a preferred embodiment of this utility model, a driven wheel is provided on the axial sleeve, and a driving wheel is provided on the drive shaft of the nut motor. The driving wheel is connected to the driven wheel via a belt, so that the nut shaft is driven by the nut motor.

[0009] As a preferred embodiment of this utility model, the back of the rotating coil is provided with a toothed ring, the drive shaft of the clamping motor extends into the toothed ring, and is provided with a gear that meshes with the toothed ring, so as to realize the clamping motor driving the toothed ring to rotate.

[0010] As a preferred embodiment of this utility model, guide bars are provided on the two opposite groove walls of the radial sliding groove, and guide grooves adapted to the guide bars are provided on the clamping seat to form a sliding guide and improve clamping stability.

[0011] As a preferred embodiment of this utility model, the gripper is provided with a hollow hole to reduce the weight of the gripper, reduce the load on the clamping motor, and improve the handling speed.

[0012] As a preferred embodiment of this utility model, the inner sidewall of the gripper is an inclined surface, which is more adaptable to the shape of the spool and provides better clamping stability.

[0013] The beneficial effects of this utility model are as follows: The structure is rationally designed. By driving the rotating coil with a clamping motor, multiple clamping seats can be driven to move closer or further apart synchronously, thereby achieving the clamping or releasing action of the coil, resulting in good clamping stability. A nut is fitted onto the nut on the coil shaft, and then the nut motor rotates to tighten or loosen the nut, eliminating the need for manual nut tightening. This facilitates quick and easy coil replacement. The entire operation is simple, fast, time-saving, and labor-saving, effectively improving work efficiency and promoting widespread application.

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0018] Figure 4 This is an exploded structural diagram of the present invention. Figure 2 . Detailed Implementation

[0019] See the example. Figures 1 to 4 This embodiment provides a horizontal wire reel universal clamp, which includes at least three clamping jaws 1, a rotating wire reel 2, a clamping seat 3, a clamping motor 4, a mounting seat 5, a nut sleeve 6, a nut shaft 7, and a nut motor 8.

[0020] In this embodiment, the number of grippers 1 is four, and the number of clamping seats 3 and radial grooves is the same as the number of grippers 1. In other embodiments, the number of grippers 1 can also be three, five, six, etc. Preferably, the grippers 1 are provided with hollow holes to reduce the weight of the grippers 1, reduce the load on the clamping motor 4, and improve the handling speed. Because one end of the coil has a smaller diameter and the other end has a larger diameter, the inner sidewall of the grippers 1 is preferably an inclined surface, which can better adapt to the shape of the coil and provide good clamping stability.

[0021] The rotating coil 2 is rotatably disposed within the clamping seat 3. Specifically, a shaft cylinder 51 is provided at the center position of the mounting base 5, and an outer bearing 52 is sleeved on the outer wall of the shaft cylinder 51. The rotating coil 2 is sleeved on the outer bearing 52, resulting in a good assembly effect, reducing the frictional resistance of the rotating coil 2, and making the rotating coil 2 run smoothly.

[0022] The rotating coil 2 has an Archimedean spiral groove on its front side, and the mounting base 5 has four radial grooves 53 symmetrically arranged in a circle on its front side. The clamping seat 3 is movably mounted on the radial grooves 53. Preferably, guide bars are provided on the opposite two groove walls of the radial grooves 53, and the clamping seat 3 has guide grooves adapted to the guide bars to form a sliding guide and improve sliding stability.

[0023] The clamp 3 is provided with threads that engage with the Archimedean spiral groove on the rotating coil 2. The jaw 1 is disposed on the clamp 3.

[0024] When the rotating coil 2 rotates, it adapts to the threads on the Archimedes spiral groove and the clamp 3, which can drive the four clamps 3 to move radially and move closer or further away from the center in sync, so as to realize the automatic centering clamping and loosening of the gripper 1.

[0025] The clamping motor 4 is fixedly mounted on the back of the clamping seat 3 via a support plate. The clamping motor 4 can drive the rotating coil 2 to rotate. Specifically, a gear ring 9 is provided on the back of the rotating coil 2. The drive shaft of the clamping motor 4 extends into the gear ring 9 and is provided with a gear 41 that meshes with the gear ring 9, so that the clamping motor 4 drives the gear ring 9 to rotate.

[0026] The nut shaft 7 is rotatably positioned at the center of the mounting base 5. The nut sleeve 6 is located at the front end of the nut shaft 7. Specifically, a front inner bearing 54 is provided at the front part of the shaft sleeve 51, and a rear inner bearing 55 is provided at the rear part. The nut shaft 7 is clearance-fitted with the inner ring of the front inner bearing 54, allowing the nut shaft 7 to slide axially. A step 71 is provided on the nut shaft 7 at the position between the front inner bearing 54 and the rear inner bearing 55. A flat part 72 is provided at the tail end of the nut shaft 7. An axial sleeve 10 is fitted on the tail end of the nut shaft 7 to allow the nut shaft 7 to move axially. The axial sleeve 10 is interference-fitted with the inner ring of the rear inner bearing 55, enabling the axial sleeve 10 to be rotated. The axial sleeve 10 has a flat hole that matches the flat part 72, allowing the axial sleeve 10 to drive the nut shaft 7 to rotate while also allowing axial movement. A spring 73 is sleeved on the nut shaft 7. The front end of the spring 73 abuts against the step 71, and the tail end abuts against the axial sleeve 10, forming an axial elastic buffer, which allows the nut shaft 7 to slide and reset axially.

[0027] The nut motor 8 is fixedly mounted on the back of the clamp 3 via a motor frame and can drive the nut shaft 7 to rotate. Specifically, the axial sleeve 10 is provided with a driven wheel 81, and the drive shaft of the nut motor 8 is provided with a driving wheel 82. The driving wheel 82 is connected to the driven wheel 81 via a belt 83, so that the nut shaft 7 is driven by the nut motor 8.

[0028] During operation, the universal horizontal wire reel clamp of this utility model is mounted on the robotic arm. When the wire reel needs to be removed, the gripper 1 is in the open state; the robotic arm moves the universal horizontal wire reel clamp to the side of the wire reel to be gripped, making the nut shaft 7 and the reel shaft coaxial, and then moves towards the reel shaft, so that the nut sleeve 6 is fitted onto the nut on the reel shaft; next, the clamping motor 4 drives the rotating coil 2 to rotate, driving the four clamping seats 3 to move closer synchronously, thereby realizing the gripper 1 to clamp the wire reel and grab it. At this time, the nut motor 8 starts, driving the nut sleeve 6 to rotate through the nut shaft 7, realizing the loosening of the nut. When the nut is loosened, under the action of the thread, it will axially compress the spring 73 towards the nut sleeve 6. The deformation of the spring 73 provides space for the nut to unscrew, effectively replacing the traditional manual nut-tightening step. When the nut is unscrewed, the robotic arm uses the universal horizontal wire reel clamp to drive the reel shaft, realizing the purpose of removing the wire reel.

[0029] When loading a reel is required, the robotic arm uses a horizontal reel universal clamp to grab the empty reel, then raises it until its hole aligns with the reel shaft, inserting the reel shaft into the hole. The robotic arm continuously pushes the empty reel axially, causing the end screw of the reel shaft to abut against the nut inside the nut sleeve 6, compressing the spring 73. At this point, the nut motor 8 starts, driving the nut sleeve 6 to rotate via the nut shaft 7, thus screwing the nut onto the reel shaft and locking it. Next, the clamping motor 4 drives the rotating reel 2 to rotate, causing the four clamping seats 3 to simultaneously separate, thereby releasing the reel from the gripper 1, achieving the purpose of loading the reel. The entire operation is simple, fast, and saves time and effort.

Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
