Description

Technical Field

[0001] This invention relates to the technical field of assembling rotors, and in particular to a semi-automatic assembly device for attaching multiple magnets to the outer cylindrical surface of a metal ring. Background Technology

[0002] A workshop produced a batch of such Figure 1 The metal ring 1 shown is a hollow elongated cylinder. The manufacturing process requires attaching multiple magnets 2 to the outer cylindrical surface of the metal ring 1 to assemble the required rotor. The rotor is installed inside the motor housing as an important component of the motor. The structure of the assembled rotor is as follows: Figures 2-3 As shown, the spacing between any two adjacent magnets 2 is equal.

[0003] The method by which the workers in the workshop assemble this rotor is as follows:

[0004] K1, the worker takes out a... Figure 1 The metal ring 1 shown is coated with glue using a brush on its outer cylindrical surface.

[0005] K2. The worker takes out a magnet 2 and presses the magnet 2 onto the outer cylindrical surface of the metal ring 1. The magnet 2 is then glued and fixed in place, thus attaching the first magnet 2 to the metal ring 1.

[0006] K3. The worker repeats step K2 multiple times to attach multiple magnets 2 to the outer cylindrical surface of the metal ring 1, thereby assembling the first required rotor. The rotor structure is as follows: Figures 2-3 As shown;

[0007] K4. Workers can assemble multiple required rotors by repeating steps K1 to K3 multiple times.

[0008] However, while the methods used by the workers in the workshop are able to assemble the required rotors, the following technical defects still exist in actual operation:

[0009] In steps K2-K3, workers need to attach magnets 2 one by one to the outer cylindrical surface of the metal ring 1. This entire operation is done manually, which undoubtedly increases the workload. Furthermore, as many as 25 magnets 2 need to be attached to a single metal ring 1. Manually attaching these magnets one by one takes a very long time, reducing the efficiency of assembling the rotor.

[0010] Therefore, there is an urgent need for a semi-automatic assembly device and method that can greatly reduce the workload of workers and greatly improve the efficiency of assembling rotors. Summary of the Invention

[0053] The present invention will be further described below with reference to the accompanying drawings. The scope of protection of the present invention is not limited to the following description:

[0054] like Figures 4-17 As shown, a semi-automatic assembly device for attaching multiple magnets to the outer cylindrical surface of a metal ring includes a machine base 3, a guide post 4 fixed on the machine base 3, and a disc 5 fixed on the top of the guide post 4. The disc 5 has a central hole 6 penetrating its top and bottom surfaces in the center. A first cylinder 7 is fixed on the top surface of the disc 5 directly above the central hole 6. A second cylinder 8 is fixed on the top surface of the first cylinder 7 and communicates with it. Multiple protective plates are fixed on the inner wall of the second cylinder 8 along its circumference. Each pair of adjacent protective plates forms a cavity 9 for accommodating magnets 2. The spacing between each pair of adjacent cavities 9 in the second cylinder 8 is equal.

[0055] A long cylindrical column 10 is fixed inside the central hole 6. The top end of the long cylindrical column 10 extends into the first cylindrical body 7. Multiple vertical support plates are fixed on the cylindrical surface of the long cylindrical column 10 along its circumference. A vertical channel 11 is formed between each two adjacent vertical support plates. Each vertical channel 11 is connected to each cavity 9. A magnetic column 12 fixed inside the long cylindrical column 10 is provided in each vertical channel 11. The spacing between each two adjacent vertical channels 11 on the long cylindrical column 10 is equal.

[0056] The top surface of the disc 5 is provided with a plurality of radial channels 13 along its circumference, and each radial channel 13 is opposite to each magnetic column 12. A lifting cylinder 14 is fixed on the bottom surface of the machine base 3. The piston rod of the lifting cylinder 14 passes through the machine base 3 upward, and a lifting plate 15 and a fixed seat 16 are fixed on the extended end in sequence. A plurality of lifting strips 17 are fixed on the fixed seat 16 around its circumference, and each lifting strip 17 is inserted into the lower port of each vertical channel 11 from bottom to top.

[0057] Four guide posts 4 are fixed between the machine base 3 and the disc 5, distributed outside the central hole 6. The lifting plate 15 has four guide holes that correspond to the guide posts 4 respectively, and the four guide holes are respectively fitted onto the four guide posts 4.

[0058] The device also includes a fixture 18 for fixing the metal ring 1. The fixture 18 includes a base 19, a boss 20, and a stepped column 21 that are sequentially fixed together from bottom to top. The fixture 18 has positioning holes 22 that sequentially penetrate the base 19, the boss 20, and the stepped column 21. The outer diameter of the boss 20 is equal to the inner diameter of the metal ring 1. The boss 20 has a limiting hole 23 that penetrates the bottom surface of the base 19. The boss 20 has multiple blind holes along its circumference in the cylindrical surface. A horizontal spring is fixed to the bottom of the blind hole. A steel ball 24 that cooperates with the blind hole is fixed to the other end of the horizontal spring. The other half of the steel ball 24 is exposed outside the boss 20.

[0059] The elongated cylinder 10 is provided with a limiting component for positioning the fixture 18. The limiting component includes a fixing rod 25 fixed on the top surface of the elongated cylinder 10. The fixing rod 25 extends upward outside the second cylinder 8. A sliding sleeve 26 and a vertical spring 27 are sleeved on the fixing rod 25. The upper and lower ends of the vertical spring 27 are fixed on the sliding sleeve 26 and the elongated cylinder 10, respectively. A limiting rod 28 parallel to the fixing rod 25 is also fixed on the top surface of the elongated cylinder 10.

[0060] The device also includes a pressurizing assembly for pressing the fixture 18 downward. The pressurizing assembly includes an arched platform 29 disposed directly above the disc 5 and a pressurizing cylinder 30 fixed on the top surface of the arched platform 29. The piston rod of the pressurizing cylinder 30 passes downward through the arched platform 29 and an annular pressure sleeve 31 is fixed on its extended end.

[0061] Each radial channel 13 of the disk 5 is provided with a plurality of magnets 2, and the innermost magnets 2 in each radial channel 13 are respectively attached and fixed to each magnetic post 12.

[0062] The device also includes a controller, which is electrically connected to the lifting cylinder 14 and the pressurizing cylinder 30 via a signal line. The operator can control the extension or retraction of the piston rods of the lifting cylinder 14 and the pressurizing cylinder 30 via the controller, thereby facilitating the operator's operation.

[0063] A semi-automatic assembly method for attaching multiple magnets to the outer cylindrical surface of a metal ring includes the following steps:

[0064] S1. Workers apply adhesive to the outer cylindrical surface of metal ring 1 using an adhesive dispensing device;

[0065] S2. Fix the metal ring 1 onto the fixture 18:

[0066] The worker took out one like Figures 13-15 The jig 18 shown and a such jig 18 Figure 1The metal ring 1 shown is placed on the outside of the boss 20 of the fixture 18 from top to bottom, and then the metal ring 1 is pressed down. The bottom surface of the metal ring 1 presses down on the exposed part of the steel ball 24. Under the pressure, the steel ball 24 extends into the blind hole and compresses the horizontal spring radially.

[0067] When the bottom surface of the metal ring 1 is supported on the chassis 19, under the elastic restoring force of the horizontal spring, the steel ball 24 presses against the inner wall of the metal ring 1, thereby fixing the metal ring 1 internally and thus fixing the metal ring 1 onto the fixture 18. Figures 18-19 As shown;

[0068] S3. The worker places the positioning hole 22 and the limiting hole 23 in the fixture 18 onto the fixing rod 25 and the limiting rod 28 of the limiting assembly, respectively, and supports the base 19 of the fixture 18 on the top surface of the sliding sleeve 26, thereby restricting the fixture 18 onto the limiting assembly. Figures 20-21 As shown, at this time, the jig 18 is exactly above the second cylinder 8;

[0069] S4. The piston rod of the pressurizing cylinder 30 of the pressurizing assembly, controlled by the worker, extends downward. The piston rod drives the annular pressure sleeve 31 to move downward. The annular pressure sleeve 31 first fits onto the outside of the stepped column 21 of the fixture 18, and its bottom surface contacts the top surface of the metal ring 1. Figure 22 As shown; then the annular pressure sleeve 31 presses down on the metal ring 1, and the metal ring 1 drives the chassis 19 to press down on the sliding sleeve 26, and the sliding sleeve 26 compresses the vertical spring 27 downward along the fixed rod 25.

[0070] When the piston rod of the pressurizing cylinder 30 is fully extended, the annular pressure sleeve 31 presses against the top surface of the second cylinder 8, and at the same time, the metal ring 1 enters the second cylinder 8, as... Figure 23 As shown;

[0071] S5. The piston rod of the control lifting cylinder 14 extends upward, the piston rod drives the lifting plate 15 to move upward, the lifting plate 15 drives the fixed seat 16 to move upward, the fixed seat 16 drives each lifting bar 17 on it, the lifting bar 17 lifts the magnet 2 upward, the magnet 2 moves upward along the vertical channel 11 and moves towards the cavity 9 of the second cylinder 8.

[0072] After the piston rod of the lifting cylinder 14 is fully extended, the magnet 2 enters the cavity 9 of the second cylinder 8 and is attached to the outer cylindrical surface of the metal ring 1. This allows multiple magnets 2 to be attached to the outer cylindrical surface of the metal ring 1 at once, thereby assembling the required rotor. The structure of the assembled rotor is as follows: Figures 2-3 As shown;

[0073] In step S2, the worker simply positions the metal ring 1 on the fixture 18; then in step S3, the fixture 18 is fixed on the limiting assembly; then in step S4, the piston rod of the pressurizing cylinder 30 is controlled to extend downward so that the metal ring 1 enters the second cylinder 8; then in step S5, the piston rod of the lifting cylinder 14 is controlled to extend upward so that the magnet 2 adsorbed and fixed on the magnetic column 12 is lifted into the cavity 9 of the second cylinder 8, thereby attaching multiple magnets 2 to the outer cylindrical surface of the metal ring 1, and finally assembling the required rotor.

[0074] Therefore, it can be seen that, compared with the assembly method in the workshop, this semi-automatic assembly device does not require workers to manually stick the magnet 2 to the outer cylindrical surface of the metal ring 1, but automatically sticks the magnet 2 to the outer cylindrical surface of the metal ring 1, thereby greatly reducing the workload of workers.

[0075] Furthermore, this semi-automatic assembly device enables the simultaneous attachment of 25 magnets 2 onto the outer cylindrical surface of the metal ring 1, eliminating the need for workers to attach these 25 magnets 2 one by one onto the outer cylindrical surface of the metal ring 1. This allows for the production of the required rotor in a short time, thereby greatly improving the efficiency of rotor assembly.

[0076] S6. Removal of the rotor:

[0077] S61, the piston rod of the pressurizing cylinder 30 retracts upward, and the piston rod drives the annular pressure sleeve 31 to move upward. Under the elastic restoring force of the vertical spring 27, the sliding sleeve 26 moves upward along the fixed rod 25. The sliding sleeve 26 drives the fixture 18 to move upward, thereby pushing the rotor out of the second cylinder 8.

[0078] S62. The worker removes the fixture 18 from the limit assembly and then removes the rotor from the fixture 18.

[0079] S7. Control the piston rod of the lifting cylinder 14 to retract downwards. The piston rod drives the lifting plate 15 and the fixed seat 16 to move downwards. The fixed seat 16 drives the lifting bar 17 to move downwards. When the lifting bar 17 passes the magnetic column 12 downwards, the next magnet in the radial channel 13 is attracted and fixed on the magnetic column 12. The worker repeats the operation of steps S2 to S6 to assemble the second rotor.
