Description

Technical Field

[0001] The present application relates to the technical field of CNC winding machines, and in particular to a shaft disassembly and assembly mechanism of a CNC winding machine. Background Art

[0002] The CNC winding machine is an advanced motor winding equipment. Its main function is to complete the winding work by accurately controlling the movement of the motor winding mechanical arm and the rotation of the winding rod. It uses a CNC system to control, which can greatly improve the efficiency and quality of motor winding, while saving a lot of manpower and time costs for the enterprise.

[0003] The existing CNC winding machine puts the winding drum on the rotating shaft, inserts one end of the rotating shaft into the chuck of the winding machine and fixes it, and controls the hydraulic rod through the CNC system to push the rotating top of the winding machine to move toward the rotating shaft. Finally, the rotating top penetrates into the top groove of the rotating shaft and holds the rotating shaft to fix it.

[0004] The above-mentioned prior art solution has the following defects: when the rotary top is pushed to move by the hydraulic rod, the rotary top may easily exert excessive pressure on the rotating shaft, causing deformation or damage to the rotating shaft. Utility Model Content

[0005] In order to reduce the steps of disassembling and assembling the rotating shaft of a CNC winding machine and improve the winding efficiency of the CNC winding machine, the present application provides a rotating shaft disassembling and assembling mechanism for a CNC winding machine.

[0006] The above technical objectives of this application are achieved through the following technical solutions:

[0008] By adopting the above technical solution, the rotary center can be moved to a position close to the rotating shaft by moving the moving box, and then the rotary center fixing column rotating shaft can be made by rotating the bidirectional screw. After the rotating shaft is fixed, the locking assembly will prevent the bidirectional screw from rotating, thereby ensuring that the rotary center can firmly fix the rotating shaft when the winding machine is working. This can reduce the operating steps for the staff when disassembling and assembling the rotating shaft, facilitate the staff to disassemble and assemble the rotating shaft, and improve the winding efficiency of the CNC winding machine.

[0009] Optionally, the telescopic assembly includes a bidirectional screw, a limiting groove is provided on the sliding box, the bidirectional screw is rotatably connected in the limiting groove, one end of the bidirectional screw extends out of the outer wall of the limiting groove and is fixedly connected to a handwheel, two sliders are threadedly connected to the bidirectional screw, the sliders slide in the limiting groove, a connecting rod is hinged on one side of the slider, and the ends of the two connecting rods away from the slider are jointly hinged to a top seat for installing a rotating top, and the top seat slides on the top of the sliding box.

[0010] By adopting the above technical solution, the hand wheel is turned to rotate the bidirectional screw to drive the slider to move, and the two sliders move toward each other along the screw. When the slider moves, the connecting rod is hinged to one end of the slider and moves closer, driving the top seat to move along the top of the sliding box toward the rotating shaft, so that the rotating top can fix the rotating shaft, which can reduce the operating steps for the staff when disassembling and assembling the rotating shaft, making it easier for the staff to disassemble and assemble the rotating shaft.

A disassembly mechanism is slidably arranged on the upper plate surface of the mounting plate 1, and the disassembly mechanism includes a sliding box 2, a first slide rail 13 is fixedly connected to the plate surface of the mounting plate 1 away from the driving box 11 by bolts, the bottom of the sliding box 2 is slidably connected to the first slide rail 13, a rack 14 is fixedly connected to the first slide rail 13 by bolts, and the length direction of the mounting plate 1, the first slide rail 13 and the rack 14 are the same.

[0034] Reference Figure 2The bottom of the sliding box 2 is equipped with a motor 21, which is mounted inside the sliding box 2 and above the rack 14. The output shaft of the motor 21 is connected to a worm 22 through a coupling, and the bottom of the sliding box 2 is rotatably connected to a driven gear 23, which is meshed with the worm 22 and the rack 14.

[0035] Combination Figure 1 and Figure 2 A telescopic component 3 is installed on the top of the sliding box 2, and a rotating top 31 is installed on the side of the telescopic component 3 close to the driving box 11. The rotating top 31 can be inserted into the top groove of the rotating shaft 15. A supporting component 4 is provided on the side of the telescopic component 3 close to the driving box 11. The supporting component 4 is located below the rotating top 31, and a locking component 5 is provided on the telescopic component 3.

[0036] Reference Figure 2 The telescopic component 3 includes a bidirectional screw 32, and the bidirectional screw 32 is provided with two sections of threads with opposite rotation directions at the midpoint of its length. A limiting groove 25 is provided on the top surface of the sliding box 2, and the top and one side close to the rotating shaft of the limiting groove 25 are open. The bidirectional screw 32 is rotatably connected to the side walls at both ends of the length direction of the limiting groove 25. Two sliders 33 are threadedly connected to the bidirectional screw 32, and the two sliders 33 are respectively threadedly connected to the two sections of the threads of the bidirectional screw 32, and the sliders 33 both slide on the inner wall of the limiting groove 25. A connecting rod 34 is hinged on one side of the slider 33 close to the drive box 11, and a top seat 35 is hinged on one end of the two connecting rods 34 away from the slider 33. The top seat 35 slides on the top of the sliding box 2. The top of the sliding box 2 is fixed with a second slide rail 24 by bolts. The second slide rail 24 has the same length direction as the rotating shaft 15. The top seat 35 slides on the second slide rail 24. One end of the bidirectional screw 32 extends out of the outer wall of one end of the limiting groove 25 in the length direction and is fixed with a handwheel 36 by bolts.

[0037] The two sliders 33 move toward each other along the screw rod 14, and the connecting rod 34 is hinged to one end of the slider 33 when the slider 33 moves, driving the top seat 35 to move along the top of the sliding box 2 toward the rotating shaft 15 until the rotating top 31 fixes the other end of the rotating shaft 15, and the rotating top 31 is moved to a position close to the rotating shaft 15 by the movement of the moving box, and then the rotating top 31 is fixed to the column rotating shaft 15 by rotating the two-way screw 32. After the rotating shaft 15 is fixed, the locking assembly 5 will prevent the two-way screw 32 from rotating, thereby ensuring that the rotating top 31 can firmly fix the rotating shaft 15 when the winding machine is working.

[0038] After the winding is completed, the supporting component 4 is extended to support the rotating shaft 15, and then the hand wheel 36 is turned to retract the rotating top 31 to release the fixation of the rotating shaft 15. The support of the rotating shaft 15 by the supporting component 4 can facilitate the staff to remove the rotating shaft 15. When the rotating shaft 15 is fixed on the winding machine again, the supporting component 4 can support the rotating shaft 15, which is convenient for the staff to move the rotating top 31 to fix the rotating shaft 15. The hand wheel 36 is turned to make the top seat 35 drive the rotating top 31 to move and fix the rotating shaft 15, which can reduce the operating steps for the staff when disassembling and assembling the rotating shaft 15, and facilitate the staff to disassemble and assemble the rotating shaft 15.

[0039] Reference Figure 2 and Figure 3 The supporting assembly 4 includes a supporting box 41, which is fixed to the top of the sliding box 2 near the driving box 11 by bolts. A crank 43 is rotatably provided on the outer wall of one side of the supporting box 41. One end of the crank 43 located in the supporting box 41 is fixed to a driving bevel gear 42 by bolts. The end of the crank 43 near the supporting box 41 is rotatably connected to the outer wall of the supporting box 41. The bottom surface inside the supporting box 41 is rotatably connected to a driven bevel gear 44, and the driven bevel gear 44 is connected to a supporting screw by a key. 45, one end of the supporting screw 45 is connected to the driven bevel gear 23, and the other end extends out of the top of the supporting box 41. The supporting screw 45 extends out of the supporting box 41 and is threadedly connected to a moving block 46 on the peripheral wall. A fixed rod 47 is welded to the top end face of the supporting box 41. A moving rod 48 is slidably connected inside the fixed rod 47. The bottom of the moving rod 48 is welded to the moving block 46, and the top of the moving rod 48 is welded to a supporting bracket 49, which is located below one end of the rotating shaft 15 close to the rotating top 31.

[0040] When the shaft disassembly and assembly mechanism of the winding machine is used, the crank 43 is turned to rotate the active bevel gear 42, and the active bevel gear 42 drives the driven bevel gear 44 and the supporting screw 45 to rotate. When the supporting screw 45 rotates, it drives the moving block 46 to move, and the moving rod 48 connected to the moving block 46 extends to the supporting bracket 49 to support the rotating shaft 15. The supporting bracket 49 supports the rotating shaft 15, which can facilitate the staff to disassemble and assemble the rotating shaft 15, thereby improving the winding efficiency of the winding machine.

[0041] Refer to 2 and Figure 4 The locking assembly 5 includes a ratchet 51, which is sleeved and welded on the bidirectional screw 32. The ratchet 51 is located on the side of the handwheel 36 close to the bidirectional screw 32. The top of the sliding box 2 is rotatably connected with a locking ring 52. The locking ring 52 is located on the side of the sliding box 2 close to the handwheel 36 and sleeved on the peripheral wall of the ratchet 51. The top of the sliding box 2 is rotatably connected with a pawl 53. Two pawls 53 are provided and are respectively located on two opposite sides of the peripheral wall of the ratchet 51. The pawl 53 can prevent the ratchet 51 from rotating in the opposite direction. The inner wall of the locking ring 52 is integrally formed with a locking block 54. Two locking blocks 54 are provided and can be moved to the two pawls 53.

[0042] When the rotating shaft 15 is removed, the locking ring 52 and the locking block 54 can be used to press the ends of the two ratchet claws 53 that are away from each other, so that the two ratchet claws 53 release the limit of the ratchet wheel 51.
