Description

Technical Field

[0001] This utility model relates to the field of motor rotor processing technology, and more specifically, to a winding device for motor rotor processing. Background Technology

[0002] The motor rotor refers to the core component of a motor that rotates around its axis. It works with the stator to achieve electromechanical energy conversion. When processing the motor rotor, it is often necessary to use a winding device. For example, the copper wire winding device for a permanent magnet motor rotor proposed in application number "CN202122819436.1" relates to the field of rotor winding technology. It includes a base, with a fixing block fixedly installed at both ends of the upper surface of the base. A hollow hydraulic pump is fixedly installed at the upper end of each fixing block. The output end of the hollow hydraulic pump is connected to a hollow connecting pipe. A square groove is opened at one end of the hollow connecting pipe. A transmission winding mechanism is movably installed at the end of the hollow connecting pipe near the square groove.

[0003] However, in the above technical solution, since the movable rod is fixedly connected to the rotor clamping block, although the clamping head can clamp different types of rotors, the shafts of different types of rotors cannot be installed inside the rotor clamping block, which causes the rotor clamping block to malfunction. Therefore, we propose a winding device for motor rotor processing to solve the above problem. Utility Model Content

[0004] The main purpose of this utility model is to provide a winding device for machining motor rotors, which solves the problem that, due to the fixed connection between the movable rod and the rotor clamping block, although the clamping head can clamp different types of rotors, the shafts of different types of rotors cannot be installed inside the rotor clamping block, thus causing the rotor clamping block to malfunction.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A winding device for machining an electric motor rotor includes a base. Fixed blocks are mounted at both ends of the upper surface of the base. A hollow hydraulic pump is mounted at the upper end of each fixed block. Clamping blocks are mounted at the output ends of the hollow hydraulic pumps, and the clamping blocks are parallel to each other. A cylinder is mounted in the middle of the base. A second motor is mounted at the output end of the cylinder. A connecting mechanism is mounted at the output end of the second motor. A rotor clamping block is engaged at the upper end of the connecting mechanism and is located between the clamping blocks. A second gear is movably mounted through the outer side of the output end of each hollow hydraulic pump. A guide rod is mounted on the side of each second gear near the clamping block. A first motor is mounted on the upper surface of the block. A transmission rod is mounted on the output end of each of the first motors. A first gear is mounted on the end of each transmission rod that is close to each other. The first gear and the second gear are meshed together. The connecting mechanism includes a support block. The support block is mounted on the upper end of the output end of the second motor. The upper surface of the support block is provided with a placement groove. A locking block is mounted on the lower end of the rotor locking block. The locking block is locked inside the placement groove. Positioning frames are movably mounted on the upper and lower ends of both sides of the locking block. Positioning holes are provided on the upper and lower ends of both sides of the placement groove. The ends of the positioning frames that are far apart from each other are locked inside the positioning holes.

[0007] Preferably, a fixed plate is installed on the outer side of the output end of the hollow hydraulic pump, and the second gear is movably sleeved on the outer side of the fixed plate. An annular slider is installed on the inner wall of the second gear and at the end near the fixed plate. The annular slider is engaged and installed inside the fixed plate.

[0008] Preferably, a second extension block is installed on one side of the output end of the hollow hydraulic pump, and a first extension block is installed on the lower end of the clamping block on the side away from each other, with the first extension block and the second extension block overlapping vertically.

[0009] Preferably, the first and second extension blocks, which overlap each other, are each connected by a plurality of bolts through threads, and the lower ends of the bolts are each connected by threads to nuts.

[0010] Preferably, the upper and lower sides of the two ends of the locking block are respectively provided with grooves, and the positioning frame is respectively installed through the inside of the groove. A spring is installed between the end of the positioning frame that is close to each other and the groove.

[0011] Preferably, the support block has movable grooves at both ends, and the movable grooves are connected to the positioning holes. Push plates are movably installed inside the movable grooves. Push rods are installed at the upper and lower ends of the push plates near the positioning holes. The push rods are respectively engaged inside the positioning holes. Extension rods are movably installed through the movable grooves at opposite ends. The extension rods are respectively connected to the push plates at opposite ends.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] (1) In this utility model, the detachable design of the support block, the placement groove and the rotor clamping block is adopted. By the locking and fixing of the positioning frame and the positioning hole, the rotor clamping block of different specifications can be quickly replaced, so that the lower end of each model of rotor can be accurately locked into the corresponding rotor clamping block. This avoids the processing limitation caused by the single specification of the rotor clamping block. At the same time, the rotor clamping block and the second motor are rigidly connected through the connection mechanism. The cooperation design of the positioning frame and the spring can provide elastic clamping force to ensure that the rotor remains stable during the processing and reduce shaking.

Fixing blocks 2 are respectively installed at both ends of the upper surface of the base 1. Hollow hydraulic pumps 3 are respectively installed at the upper ends of the interior of the fixing blocks 2.

A cylinder 7 is installed in the middle of the interior of the base 1. A second motor 8 is installed at the output end of the cylinder 7. A connecting mechanism 9 is installed at the output end of the second motor 8. A rotor clamping block 10 is engaged at the upper end of the connecting mechanism 9, and the rotor clamping block 10 is located between the clamping blocks 14. A second gear 12 is movably installed through the outer side of the output end of the hollow hydraulic pump 3. A guide rod 13 is respectively installed on the side of the second gear 12 near the clamping block 14. The fixing blocks 2... The upper surface is respectively equipped with a first motor 4, and the output end of the first motor 4 is respectively equipped with a transmission rod 5. The ends of the transmission rods 5 that are close to each other are respectively equipped with a first gear 6. The first gear 6 and the second gear 12 are meshed and connected. The connecting mechanism 9 includes a support block 901, which is installed on the upper end of the output end of the second motor 8. The upper surface of the support block 901 is provided with a placement groove 902. The lower end of the rotor clamping block 10 is equipped with a locking block 903, which is locked and installed inside the placement groove 902. The upper and lower ends of both sides of the locking block 903 are respectively movably installed with positioning frames 905. The upper and lower ends of both sides of the placement groove 902 are respectively provided with positioning holes 907. The ends of the positioning frames 905 that are far apart from each other are locked and installed inside the positioning holes 907.

[0024] like Figure 4As shown, in another embodiment of this utility model, a fixed plate 11 is installed on the outer side of the output end of the hollow hydraulic pump 3. Second gears 12 are movably sleeved on the outer side of the fixed plate 11. Annular sliders 18 are installed on the inner wall of the second gears 12 near the fixed plate 11. The annular sliders 18 are respectively engaged inside the fixed plate 11. A second extension block 16 is installed on one side of the output end of the hollow hydraulic pump 3. A first extension block 15 is installed on the lower end of the clamping blocks 14 on the side furthest from each other. The first extension block 15 and the second extension block 16 overlap vertically. Several bolts 17 are threaded through and installed between the overlapping first extension block 15 and second extension block 16. Nuts are threaded onto the lower ends of the bolts 17 to engage. The upper and lower sides of the inner ends of block 903 are respectively provided with grooves 904. Positioning brackets 905 are respectively installed through the inside of the grooves 904. Springs 906 are respectively installed between the adjacent ends of the positioning brackets 905 and the grooves 904. The inner ends of support block 901 are respectively provided with movable grooves 908, and the movable grooves 908 are connected through to the positioning holes 907. Push plates 909 are movably installed inside the movable grooves 908. Push rods 910 are respectively installed at the upper and lower ends of the push plate 909 near the positioning holes 907. The push rods 910 are respectively engaged inside the positioning holes 907. Extension rods 911 are movably installed through the inner ends of the movable grooves 908 and at the opposite ends. The adjacent ends of the extension rods 911 are respectively connected to the push plates 909.

[0025] When different specifications of motor rotors need to be processed, the extension rod 911 in the connecting mechanism 9 is pushed. Then, the extension rod 911 drives the push plate 909 to move in the movable slot 908, so that the push plate 909 pushes the positioning frame 905 out of the positioning hole 907 of the support block 901 through the push rod 910. Then, the user can take out the old rotor clamping block 10, insert the locking block 903 of the rotor clamping block 10 that is adapted to the new rotor specification into the placement slot 902 of the support block 901, and then release the extension rod 911. Under the elastic force of the spring 906, the positioning frame 905 pops out and locks into the positioning hole 907, completing the fixing of the rotor clamping block 10. Then, the user removes the bolt 17 by thread to replace the clamping block 14. The adapted clamping block 14 is connected to the first extension block 15 and the second extension block 16 and then the user can remove the bolt 17 by thread. During installation, bolt 17 and nut are used to position the first extension block 15 and the second extension block 16. Then, the rotor to be processed is placed in the clamping groove of the rotor clamping block 10. The cylinder 7 inside the base 1 is started. The cylinder 7 pushes the second motor 8 and the rotor clamping block 10 upward, so that the rotor is aligned with the clamping blocks 14 on both sides. Then, the hollow hydraulic pump 3 is started. Its output end pushes the clamping block 14 to move towards the center, so that the clamping block 14 clamps and positions the rotor. Then, the copper wire is passed through the guide rod 13 on the second gear 12 outside the output end of the hollow hydraulic pump 3. Then, the first motor 4 is started. It drives the first gear 6 to rotate through the transmission rod 5. The first gear 6 meshes with the second gear 12, driving the second gear 12 to rotate around the output end of the hollow hydraulic pump 3. Then, as the second gear 12 drives the guide rod 13 to rotate synchronously, the copper wire is wound around the outer circumference of the rotor with the rotation of the guide rod 13.

[0026] The annular slider 18 on the outer side of the fixed plate 11 engages with the inner wall of the second gear 12 to ensure that the second gear 12 maintains coaxiality when rotating, and to prevent the copper wire from winding and shifting due to shaking.

[0027] The cylinder 7 can adjust the vertical height of the rotor clamping block 10 to adapt to rotors of different lengths and avoid clamping failure due to differences in rotor shaft length.

[0028] The engagement of the positioning bracket 905 with the positioning hole 907, combined with the elastic clamping force of the spring 906, ensures that the rotor clamping block 10 does not wobble during processing, thus improving winding accuracy.

[0029] The working principle of a winding device for machining motor rotors:

[0030] In use, when different specifications of motor rotors need to be processed, firstly, push the extension rod 911 in the connecting mechanism 9. Then, the extension rod 911 drives the push plate 909 to move in the movable slot 908, so that the push plate 909 pushes the positioning frame 905 out of the positioning hole 907 of the support block 901 through the push rod 910. Then, the user can take out the old rotor clamping block 10, insert the clamping block 903 of the rotor clamping block 10 that is adapted to the new rotor specification into the placement slot 902 of the support block 901, and then release the extension rod 911. Under the elastic force of the spring 906, the positioning frame 905 pops out and locks into the positioning hole 907, completing the fixing of the rotor clamping block 10. Then, the user removes the bolt 17 by thread to replace the clamping block 14. Connect the adapted clamping block 14 with the first extension block 15 and the second extension block 16. Then, the user can replace the bolt 17 by thread. 7. Install the rotor by using bolts 17 and nuts to position the first extension block 15 and the second extension block 16. Then, place the rotor to be processed into the clamping groove of the rotor clamping block 10. Start the cylinder 7 inside the base 1. The cylinder 7 pushes the second motor 8 and the rotor clamping block 10 upward to align the rotor with the clamping blocks 14 on both sides. Then, start the hollow hydraulic pump 3. Its output end pushes the clamping block 14 to move towards the center so that the clamping block 14 clamps and positions the rotor. Then, pass the copper wire through the guide rod 13 on the second gear 12 outside the output end of the hollow hydraulic pump 3. Then, start the first motor 4. It drives the first gear 6 to rotate through the transmission rod 5. The first gear 6 meshes with the second gear 12 and drives the second gear 12 to rotate around the output end of the hollow hydraulic pump 3. Then, as the second gear 12 drives the guide rod 13 to rotate synchronously, the copper wire is wound around the outer circumference of the rotor with the rotation of the guide rod 13.

[0031] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
