Description

Technical Field

[0001] The invention belongs to the technical field of spinning machines, in particular to a spinning machine for producing a wheel rim and an operating method thereof. Background Art

[0002] The rim, commonly known as the wheel rim, is a component around the wheel used to install and support the tire. It is located on the outer edge of the wheel and together with the spokes, it forms the wheel. As an important component of the wheel, the rim has an important impact on the safe driving and handling performance of the car. Therefore, the production and processing of the rim needs to be strictly controlled. At present, the common rim processing methods are mostly divided into gravity casting, forging, low-pressure precision casting and spinning technology; and the spinning technology often requires the cooperation of a spinning machine when used. When processing the rim, the spinning machine mainly preheats the blank and fixes it to the mold, then drives the blank to rotate at high speed through the clamping part, and at the same time, the rotating blank is squeezed and stretched by the spinning wheel to shape the shape of the rim. Finally, the high-speed rotation and high temperature are maintained, and the rim is stretched repeatedly under high pressure to reach the pre-designed size specifications.

[0003] In the prior art, wheel rims are generally made of aluminum alloy materials. Due to the relatively low melting point of aluminum alloy, when the spinning machine is used for large-scale continuous production, the long-term friction between the spinning wheel and the rim will cause the temperature of the spinning wheel to rise significantly, which will lead to local material adhesion on the surface of the spinning wheel. This problem will then cause scratches on the product surface during the processing of subsequent rims, reducing product quality. In order to cope with this situation, the spinning wheel needs to be polished and maintained regularly. However, the existing polishing methods mainly rely on manual grinding or automatic grinding with special polishing equipment after the spinning wheel is disassembled. Both of these treatment methods significantly reduce the working efficiency of the spinning machine, causing production interruptions and increasing time costs.

[0004] To this end, the present invention provides a spinning machine for producing a wheel rim and an operating method thereof. Summary of the invention

[0005] In order to make up for the shortcomings of the prior art and solve the problem that in the prior art, wheel rims are generally made of aluminum alloy materials, and due to the relatively low melting point of aluminum alloy, when a spinning machine is used for large-scale continuous production, the long-term friction between the spinning wheel and the rim will cause the temperature of the spinning wheel to rise significantly, thereby causing material adhesion to appear locally on the surface of the spinning wheel. This problem will subsequently cause scratches on the product surface during the processing of subsequent rims, thereby reducing product quality. In order to cope with this situation, the spinning wheel needs to be polished and maintained regularly. However, the existing polishing method mainly relies on manual grinding or automatic grinding with special polishing equipment after the spinning wheel is disassembled.

DETAILED DESCRIPTION

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0037] like Figure 1-Figure 12As shown, a wheel rim production spinning machine according to an embodiment of the present invention comprises a chassis 1, a mounting seat 2 is slidably connected in the inner cavity of the chassis 1, a wheel disc 5 is rotatably connected to the mounting seat 2, a gear ring 6 is fixedly connected to the wheel disc 5, a motor 3 is fixedly mounted on one side of the mounting seat 2, a gear 4 is fixedly connected to the output end of the motor 3, the gear 4 is meshingly connected to the gear ring 6, a plurality of mounting plates 7 are evenly fixedly connected to one side of the wheel disc 5, a cylinder 8 is fixedly mounted on the mounting plate 7, a mounting frame 9 is fixedly connected to the output end of the cylinder 8, and the mounting frame 9 is rotatably connected with a rotating shaft 10, a rotating wheel 11 is fixedly connected to the rotating shaft 10, a cylinder 2 13 is fixedly installed on the top of the side of the wheel disc 5 away from the mounting plate 7, a bracket 14 is fixedly connected to the output end of the cylinder 2 13, a maintenance box 15 is fixedly connected to the side of the bracket 14 close to the wheel disc 5, and a polishing machine is arranged in the maintenance box 15; when the spinning machine needs to maintain the rotating wheel 11 after working for a period of time, the staff can start the cylinder 2 13, so that the bracket 14 drives the maintenance box 15 to slide toward the wheel disc 5 until the maintenance box 15 The wheel 11 is moved to the bottom of the top of the wheel disc 5, and the mounting frame 9 is driven to move by the cylinder 8, so that the wheel 11 slides downward into the maintenance box 15, and the surface of the wheel 11 can be polished and ground by the polishing machine to clean the sticky material attached to the surface of the wheel 11, which effectively solves the problem that in the prior art, the wheel rim is generally made of aluminum alloy material, and the aluminum alloy has a relatively low melting point. When the spinning machine is used for large-scale continuous production, the long-term friction between the wheel 11 and the rim will cause the temperature of the wheel 11 to rise significantly, and then cause the material to adhere locally on the surface of the wheel 11. This problem will then cause scratches on the product surface when processing subsequent rims, reducing product quality. In order to cope with this situation, the wheel 11 needs to be polished and maintained regularly. However, the existing polishing method mainly relies on manual grinding or automatic grinding with special polishing equipment after the wheel 11 is disassembled. Both of these treatment methods significantly reduce the working efficiency of the spinning machine, causing production interruption and increasing time cost.

[0038] The polishing machine includes a motor 2 17, a mounting rod 22 and a polishing wheel 24. An L-shaped plate 16 is fixedly connected to the outer wall of the maintenance box 15. The motor 2 17 is fixedly installed on the side of the L-shaped plate 16 close to the maintenance box 15. The output end of the motor 2 17 is fixedly connected to a rotating rod 37. The rotating rod 37 is fixedly connected to a gear 2 18. The bottom of the gear 2 18 is meshed and connected to a gear 3 19. The gear 3 19 is fixedly connected to a rotating sleeve 20. The rotating sleeve 20 is rotatably connected to the outer wall of the maintenance box 15. The inner cavity of the rotating sleeve 20 is provided with a mounting rod 22. The end of the mounting rod 22 away from the L-shaped plate 16 extends into the inner cavity of the maintenance box 15 and is fixedly connected to the polishing wheel 24. The rotating rod One end of 37 away from motor 2 17 extends into the inner cavity of the maintenance box 15 and is provided with a locking assembly; during operation, when the rotary wheel 11 is polished, the motor 2 17 drives the rotating rod 37 in the forward direction, so that the gear 3 19 meshing with the gear 2 18 drives the rotating sleeve 20 to rotate, and then the polishing wheel 24 on the mounting rod 22 rotates, so that the rotary wheel 11 that slides down into the maintenance box 15 is automatically polished. After the rotary wheel 11 on the top of the wheel disc 5 is polished, the motor 13 drives the gear 14 to rotate, so that the gear ring 6 drives the wheel disc 5 to rotate, so that other unpolished rotary wheels 11 can enter the maintenance box 15 to complete the polishing maintenance operation.

[0039] The locking assembly includes an electromagnet 38, a permanent magnet 39 and a cross block 41. A cross slot 12 is provided on the end of the rotating shaft 10. The electromagnet 38 is fixedly connected to the inner cavity wall of the rotating rod 37. A permanent magnet 39 is provided on the side of the electromagnet 38 away from the motor 17. The permanent magnet 39 is T-shaped. The permanent magnet 39 is slidably connected to the inner cavity of the rotating rod 37. The end of the permanent magnet 39 away from the electromagnet 38 extends to the outside of the rotating rod 37 and is fixedly connected to the cross block 41. The cross block 41 is adapted to the cross slot 12. A spring 40 is fixedly connected between the permanent magnet 39 and the inner cavity of the rotating rod 37. When working, when the rotating wheel 11 enters After being placed in the maintenance box 15, the electromagnet 38 is energized and generates a magnetic repulsion force with the permanent magnet 39, so that the permanent magnet 39 compresses the spring 2 40 and drives the cross block 41 to slide into the cross groove 12 of the rotating shaft 10, thereby locking the rotating shaft 10. As a result, the motor 2 17 drives the polishing wheel 24 and the rotating rod 37 to rotate, while the rotating shaft 10 drives the rotating wheel 11 to rotate under the drive of the cross block 41. Moreover, due to the meshing action of the gear 2 18 and the gear 3 19, the rotation direction of the rotating wheel 11 is opposite to that of the polishing wheel 24, so that the polishing wheel 24 can polish the rotating wheel 11 more efficiently and evenly.

[0040] The top of the maintenance box 15 is fixedly connected with an ear plate 42, and a worm 43 is rotatably connected to the ear plate 42. A gear 44 is fixedly connected to the end of the worm 43 close to the motor 2 17, and the gear 44 is meshed with the gear 2 18. The bottom of the worm 43 is meshed with a worm wheel 45, and a bidirectional threaded rod 46 is fixedly connected to the worm wheel 45. The two ends of the bidirectional threaded rod 46 are respectively rotatably connected to the inner walls of the two sides of the maintenance box 15. The bidirectional threaded rod 46 is symmetrically threaded with two screw sleeves 47, and the screw sleeve 47 is fixedly connected with an L-shaped rod 48, a flushing assembly is provided at the bottom end of the L-shaped rod 48, and the flushing assembly is adapted to the rotating wheel 11. Support rods 49 are fixedly connected to the inner walls on both sides of the maintenance box 15, and the L-shaped rod 48 is slidably connected to the support rods 49; when working, when the motor 2 17 rotates forward, the gear 44 meshing with the gear 2 18 rotates accordingly, and the two-way threaded rod 46 is driven to rotate through the cooperation of the worm 43 and the worm wheel 45, so that the two screw sleeves 47 slide in the opposite direction, and then the two L-shaped rods 48 drive the two flushing assemblies away from the rotating wheel 11.

[0041] The flushing assembly includes a fixed block 50, a fixed block 51, a water spray plate 52 and a sponge block 53. The bottom end of the L-shaped rod 48 is fixedly connected to the fixed block 50, and a fixed block 51 is arranged below the fixed block 50. The fixed block 50 is fixedly connected to the water spray plate 52, and the side of the water spray plate 52 away from the fixed block 50 is evenly provided with spray holes 55. The top of the water spray plate 52 is connected to a water inlet pipe 54, and the water inlet pipe 54 is externally connected to a liquid supply device. The sponge block 53 is fixedly connected to the fixed block 51, and the bottom of the inner cavity of the maintenance box 15 is connected to a drain pipe. During operation, after the L-shaped rod 48 drives the fixed block 50 and the fixed block 51 away from the rotary wheel 11, the polishing wheel 24 is polishing the rotary wheel 11. The water inlet pipe 54 is externally connected to the liquid supply device to send the cleaning liquid into the water spray plate 52, and then spray it out from the spray hole 55 to spray the rotary wheel 11, thereby assisting The polishing operation of the polishing wheel 24 is completed, and the motor 17 is reversed, so that the screw sleeve 47 drives the water spray plate 52 and the sponge block 53 to move toward the rotating wheel 11 until the sponge block 53 fits the surface of the rotating wheel 11. At this time, the water spray plate 52 is not in contact with the rotating wheel 11, the motor 17 is stopped, and the electromagnet 38 is powered off, so that the permanent magnet 39 drives the cross block 41 away from the cross groove 12 of the rotating shaft 10 under the elastic force of the spring 40. Thereafter, the rotating wheel 11 continues to rotate under the action of inertia and continuously contacts the sponge block 53 until it stops, which can avoid excessive friction between the rotating wheel 11 and the sponge block 53, and enable the sponge block 53 to wipe and absorb water from the rotating wheel 11, and clean the water stains on the rotating wheel 11. During the polishing process, the cleaning liquid sprayed by the water spray plate 52 is discharged through the drain pipe under the maintenance box 15.

[0042] A pair of water filter plates 58 are fixedly connected to both sides of the maintenance box 15, the sponge block 53 is adapted to the pair of water filter plates 58, and filter holes 59 are evenly opened on the water filter plates 58. The water filter plates 58 are composed of a horizontal plate and an inclined plate. The opposite side end surfaces of the pair of water filter plates 58 are each provided with a horizontal groove 1 60, an inclined groove 1 61, multiple square grooves 62, multiple inclined grooves 2 63, a vertical groove 64 and a horizontal groove 2 65. The horizontal groove 1 60 is connected to the top of the inclined groove 1 61, the square groove 62 and the inclined groove 2 63 are spaced and connected to each other, the bottom of the inclined groove 1 61 is connected to a square groove 62 on the side away from the inner wall of the maintenance box 15, the bottom of the vertical groove 64 is connected to a inclined groove 2 63 on the side close to the inner wall of the maintenance box 15, the top of the vertical groove 64 is connected to the horizontal groove 2 65, and the horizontal groove 2 65 is far away from the vertical groove 64. One side of the sponge block 53 is provided with an inclined surface, and the horizontal groove 1 60 and the horizontal groove 2 65 are on the same horizontal plane; during operation, after the sponge block 53 completes the cleaning and wiping of the rotary wheel 11, the motor 2 17 is driven to rotate forward to drive the sponge block 53 to move to the side of the water filter plate 58 again. During this process, the sponge block 53 contacts and is squeezed with a pair of water filter plates 58, so that the water absorbed in the sponge block 53 is discharged from the filter holes 59 on the water filter plates 58, thereby ensuring the drying of the sponge block 53. The horizontal groove 1 60, the inclined groove 1 61, the square groove 62, the inclined groove 2 63, the vertical groove 64 and the horizontal groove 2 65 provided on the water filter plate 58 cooperate with the fixed block 1 50 and the fixed block 2 51 to drive the sponge block 53 to shake up and down, and the impurities generated by the rotary wheel 11 during the polishing process and transferred to the sponge block 53 during the cleaning process are shaken off.

[0043] A T-shaped rod 2 56 is slidably connected in the inner cavity of the fixed block 1 50, and the bottom end of the T-shaped rod 2 56 extends to the bottom of the fixed block 1 50 and is fixedly connected to the top of the fixed block 2 51. A spring 3 57 is fixedly connected between the T-shaped rod 2 56 and the inner cavity of the fixed block 1 50. Receiving grooves 2 66 are provided on the outer walls of both sides of the fixed block 2 51, and a spring 67 is fixedly connected to the inner wall of the receiving groove 2 66. A limiting block 2 68 is slidably connected in the receiving groove 2 66, and one end of the limiting block 2 68 is in contact with the spring 67, and the other end of the limiting block 2 68 extends away from the spring 67. The slider 69 is fixed to the outside of the fixed block 51, and the slider 69 is slidably connected with the transverse groove 1 60, the inclined groove 1 61, the square groove 62, the inclined groove 2 63, the vertical groove 64 and the transverse groove 2 65. When working, when the fixed block 1 50 and the fixed block 2 51 slide toward the side of the water filter plate 58 driven by the screw sleeve 47, the slider 69 on the fixed block 2 51 first slides into the transverse groove 1 60. At this time, the spring 3 57 is in a natural state. When the slider 69 slides from the transverse groove 1 60 into the inclined groove 1 61, the fixed block 2 51 drives the T-bar 2 56 downward. The slider 69 slides and compresses the spring three 57 until the slider 69 slides into the square groove 62. The T-bar two 56 drives the fixed block two 51 to quickly reset under the elastic force of the spring three 57. During this process, the slider 69 impacts the top of the inner wall of the square groove 62, causing the sponge block 53 to vibrate, which is convenient for shaking off the impurities attached to the sponge block 53. When the slider 69 slides from the square groove 62 to the inclined groove two 63, the spring three 57 is squeezed by the T-bar two 56 again until the slider 69 slides into the square groove 62 again, and the spring three 57 is restored again, and so on. Until the slider 69 slides from the inclined groove 2 63 into the vertical groove 64 and directly slides up into the transverse groove 2 65, the spring 3 57 is completely restored. Thereafter, when the motor 2 17 reverses to make the sponge block 53 move away from the water filter plate 58, the slider 69 slides along the transverse groove 2 65 until the slider 69 contacts the inclined surface of the transverse groove 2 65 and slides into the transverse groove 1 60 again. During this process, the slider 69 is squeezed by the inclined surface of the transverse groove 2 65 to drive the limit block 2 68 to compress the spring piece 67. When the slider 69 slides into the transverse groove 1 60, it is reset under the elastic force of the spring piece 67.

An annular block 26 is sleeved on the outer side of the guide ring 31, and a connecting rod 25 is fixedly connected between the annular block 26 and the polishing wheel 24. A guide piece is provided on the annular block 26, and an annular groove 1 32 is provided on the side of the guide ring 31 away from the polishing wheel 24, and an annular groove 2 33 is provided on the side of the guide ring 31 close to the polishing wheel 24. A spiral groove 34 is provided on the guide ring 31, and the spiral groove 34 is located between the annular groove 1 32 and the annular groove 2 33, and the guide piece cooperates with the annular groove 1 32, the annular groove 2 33 and the spiral groove 34; when working, when the motor 2 17 is turned on, the rotating sleeve When the cylinder 20 drives the mounting rod 22 to rotate, the annular block 26 connected to the polishing wheel 24 drives the guide to slide along the annular groove 1 32, the spiral groove 34 and the annular groove 2 33 of the guide ring 31, so that the mounting rod 22 can drive the polishing wheel 24 to slide axially along the limit groove 21 opened in the rotating sleeve 20. By controlling the forward and reverse rotation of the motor 2 17, it is achieved that when the motor 2 17 rotates forward, the polishing wheel 24 slides and rotates toward the side of the rotating wheel 11, and the sponge block 53 moves away from the rotating wheel 11. When the motor 2 17 reverses, the polishing wheel 24 moves away from the rotating wheel 11, and the sponge block 53 approaches the rotating wheel 11 until it fits, and the motor 2 17 stops, effectively preventing the debris generated by the polishing wheel 24 during polishing from directly splashing onto the sponge block 53. When the sponge block 53 is wiping, the polishing wheel 24 affects the rotating wheel 11 under the action of inertia.

[0045] The guide member includes a T-shaped rod 28, a spring 29 and a guide block 30. A receiving groove 27 is provided on the inner side of the annular block 26. The inner cavity of the receiving groove 27 is slidably connected with a T-shaped rod 28. A spring 29 is fixedly connected between the T-shaped rod 28 and the inner wall of the receiving groove 27. One end of the T-shaped rod 28 away from the spring 29 extends to the outer side of the receiving groove 27 and is movably connected with the guide block 30. The guide block 30 is slidably connected with the annular groove 1 32, the annular groove 2 33 and the spiral groove 34. A stopper 35 is fixedly connected to the connection between the annular groove 1 32 and the spiral groove 34. The connection between the annular groove 2 33 and the spiral groove 34 A stopper 2 36 is fixedly connected, and both the stopper 1 35 and the stopper 2 36 are provided with inclined surfaces; during operation, when the rotary wheel 11 enters the maintenance box 15 and the motor 2 17 rotates forward, the guide block 30 on the annular block 26 rotates one circle from the annular groove 1 32 under the drive of the polishing wheel 24, and then passes through the stopper 1 35 and directly slides into the spiral groove 34. When the guide block 30 passes through the inclined surface of the stopper 1 35, it is squeezed and drives the T-bar 1 28 to slide upward and compress the spring 1 29, until the guide block 30 slides into the spiral groove 34, and the spring 1 29 is restored. When the guide block 30 slides to the connecting point between the spiral groove 34 and the annular groove 2 33, due to The guide block 30 is blocked by the second stopper 36 and directly slides into the second annular groove 33. Thereafter, it continuously rotates along the second annular groove 33. When the guide block 30 passes the inclined surface of the second stopper 36, the T-bar 1 28 compresses the spring 1 29 until the guide block 30 leaves the second stopper 36 and slides into the second annular groove 33 again. At this time, the electromagnet 38 is in the energized state, the polishing wheel 24 rotates relative to the rotating wheel 11, and the grinding operation of the rotating wheel 11 is realized. The screw sleeve 47 continues to slide on the bidirectional threaded rod 46 until the end of the bidirectional threaded rod 46. At this time, the control motor 17 is reversed, and the polishing wheel 24 drives the annular block 26 to reverse, so that The guide block 30 slides directly from the annular groove 2 33 into the spiral groove 34, and under the action of the stop block 1 35, slides from the spiral groove 34 into the annular groove 1 32, and then continuously rotates along the annular groove 1 32. At this time, the screw sleeve 47 drives the sponge block 53 to slide toward the rotating wheel 11 until the sponge block 53 contacts the rotating wheel 11. The motor 2 17 stops, the electromagnet 38 is powered off, and the sponge block 53 can wipe and clean the rotating wheel 11 that rotates by inertia.

[0046] An operating method of a spinning machine for producing a wheel rim, the operating method is applicable to the above-mentioned spinning machine for producing a wheel rim, and the operating method comprises the following steps:

[0047] S1: When the rotary wheel 11 needs maintenance, the staff can start the cylinder 2 13, so that the bracket 14 drives the maintenance box 15 to slide toward the wheel disc 5, until the maintenance box 15 moves to the top of the wheel disc 5 directly below the rotary wheel 11, and the cylinder 1 8 drives the mounting frame 9 to move, so that the rotary wheel 11 slides downward into the maintenance box 15;

[0048] S2: After the rotary wheel 11 enters the maintenance box 15, the surface of the rotary wheel 11 can be polished and ground by a polishing machine to clean the sticky material attached to the surface of the rotary wheel 11;

[0049] S3: After the rotating wheel 11 on the top of the wheel disc 5 is polished, the motor 3 drives the gear 4 to rotate, so that the gear ring 6 drives the wheel disc 5 to rotate, and then the other unpolished rotating wheels 11 can enter the maintenance box 15 to complete the polishing maintenance operation.

[0050] Working principle: when the spinning machine needs to maintain the rotating wheel 11 after working for a period of time, the staff can start the cylinder 2 13 to make the bracket 14 drive the maintenance box 15 to slide toward the wheel disc 5 until the maintenance box 15 moves to the top of the wheel disc 5 directly below the rotating wheel 11, and drive the mounting frame 9 to move through the cylinder 1 8, so that the rotating wheel 11 slides downward into the maintenance box 15, and the surface of the rotating wheel 11 can be polished and polished by the polishing machine to clean the sticky material attached to the surface of the rotating wheel 11. When polishing the rotating wheel 11, the rotating rod 37 is driven forward by the motor 2 17, so that the gear 3 19 meshing with the gear 2 18 drives the rotating sleeve 20 to rotate, and then the polishing wheel 24 on the mounting rod 22 rotates, so as to slide down to the maintenance box 15. The rotating wheels 11 are automatically polished. After one of the rotating wheels 11 is polished, the motor 13 drives the gear 14 to rotate, so that the gear ring 6 drives the wheel disc 5 to rotate, and then the other unpolished rotating wheels 11 can enter the maintenance box 15 to complete the polishing maintenance operation. When the rotating wheel 11 enters the maintenance box 15, the electromagnet 38 is energized and generates a magnetic repulsion force with the permanent magnet 39, so that the permanent magnet 39 compresses the spring 2 40 and drives the cross block 41 to slide into the cross groove 12 of the rotating shaft 10, thereby locking the rotating shaft 10, and then the motor 2 17 drives the polishing wheel 24 and the rotating rod 37 to rotate. At the same time, the rotating shaft 10 drives the rotating wheel 11 to rotate under the drive of the cross block 41, and because of the meshing action of the gear 2 18 and the gear 3 19, the rotating wheel 11 The rotation direction is opposite to that of the polishing wheel 24, so that the polishing wheel 24 can polish the rotary wheel 11 more efficiently and evenly. When the motor 2 17 rotates forward, the gear 44 meshing with the gear 2 18 rotates accordingly, and the cooperation of the worm 43 and the worm wheel 45 drives the bidirectional threaded rod 46 to rotate, so that the two screw sleeves 47 slide in the opposite direction, and then the two L-shaped rods 48 drive the fixed block 1 50 and the fixed block 2 51 away from the rotary wheel 11. During the polishing of the rotary wheel 11 by the polishing wheel 24, the water inlet pipe 54 is externally connected to the liquid supply equipment to send the cleaning liquid into the water spray plate 52, and then spray it out from the spray hole 55, so as to realize the spraying of the rotary wheel 11 and assist the polishing operation of the polishing wheel 24. When the polishing operation is completed, the motor 2 17 is reversed, so that the screw sleeve 47 drives the water spray plate 52 and the sponge block 53 move toward the rotating wheel 11 until the sponge block 53 is in contact with the surface of the rotating wheel 11. At this time, the water spray plate 52 is not in contact with the rotating wheel 11, the motor 17 is stopped, and the electromagnet 38 is powered off, so that the permanent magnet 39 drives the cross block 41 away from the cross groove 12 of the rotating shaft 10 under the elastic force of the spring 2 40. Thereafter, the rotating wheel 11 continues to rotate under the action of inertia and continuously contacts the sponge block 53 until it stops, which can avoid excessive friction between the rotating wheel 11 and the sponge block 53 and enable the sponge block 53 to wipe and absorb water from the rotating wheel 11 and clean the water stains on the rotating wheel 11. During the polishing process, the cleaning liquid sprayed by the water spray plate 52 is discharged through the drain pipe under the maintenance box 15. When the sponge block 53 finishes cleaning and wiping the rotating wheel 11,The motor 2 17 is rotated forward to drive the sponge block 53 to move toward the side of the water filter plate 58 again. During this process, the slider 69 on the fixed block 2 51 first slides into the horizontal groove 1 60. At this time, the spring 3 57 is in a natural state. When the slider 69 slides from the horizontal groove 1 60 into the inclined groove 1 61, the fixed block 2 51 drives the T-bar 2 56 to slide downward and compresses the spring 3 57 until the slider 69 slides into the square groove 62. The T-bar 2 56 drives the fixed block 2 51 to reset quickly under the elastic force of the spring 3 57. During this process, the slider 69 impacts the top of the inner wall of the square groove 62, causing the sponge block 53 to shake, which is convenient for shaking off the impurities attached to the sponge block 53. When the slider 69 slides from the square groove 62 to the inclined groove 2 63, the spring 3 57 is again compressed by the T-bar The slider 69 is squeezed by the second groove 56 until the slider 69 slides into the square groove 62 again, and the spring three 57 is restored again, and so on and so forth until the slider 69 slides from the oblique groove two 63 into the vertical groove 64 and directly slides up into the horizontal groove two 65, and the spring three 57 is completely restored. Thereafter, when the motor two 17 is reversed to make the sponge block 53 move away from the water filter plate 58, the slider 69 slides along the horizontal groove two 65 until the slider 69 contacts the inclined surface of the horizontal groove two 65 and slides into the horizontal groove one 60 again. In this process, the slider 69 is squeezed by the inclined surface of the horizontal groove two 65 to drive the limit block two 68 to compress the spring piece 67. When the slider 69 slides into the horizontal groove one 60, it is reset under the elastic force of the spring piece 67, and the water absorbed in the sponge block 53 is squeezed out through a pair of water filter plates 58, thereby ensuring that the sponge When the rotary wheel 11 enters the maintenance box 15 and the motor 17 rotates forward, the guide block 30 on the annular block 26 rotates one circle from the annular groove 32 under the drive of the polishing wheel 24, and then passes through the block 35 and directly slides into the spiral groove 34. When the guide block 30 passes the inclined surface of the block 35, it is squeezed and drives the T-bar 28 to slide upward and compress the spring 29 until the guide block 30 slides into the spiral groove 34. The spring 29 is restored. When the guide block 30 slides to the connecting part of the spiral groove 34 and the annular groove 23, it is blocked by the block 236 and directly slides into the annular groove 23. Thereafter, it rotates continuously along the annular groove 23. When the guide block 30 passes the inclined surface of the block 236, the T-bar 28 compresses the spring 29. , until the guide block 30 leaves the stopper 2 36 and slides into the annular groove 2 33 again. At this time, the electromagnet 38 is in the energized state, the polishing wheel 24 rotates relative to the rotating wheel 11, and the grinding operation of the rotating wheel 11 is realized. The screw sleeve 47 continues to slide on the bidirectional threaded rod 46 until the end of the bidirectional threaded rod 46. At this time, the control motor 2 17 is reversed, and the polishing wheel 24 drives the annular block 26 to reverse, so that the guide block 30 slides directly from the annular groove 2 33 into the spiral groove 34, and under the action of the stopper 1 35, after sliding from the spiral groove 34 into the annular groove 1 32, it rotates continuously along the annular groove 1 32. At this time, the screw sleeve 47 drives the sponge block 53 to slide toward the rotating wheel 11, until the sponge block 53 contacts the rotating wheel 11, the motor 2 17 stops, and the electromagnet 38 is powered off.The sponge block 53 can wipe and clean the rotating wheel 11 that rotates by inertia, and so on, so as to achieve intermittent grinding and cleaning of the rotating wheel 11, so that the staff can observe the grinding effect of the rotating wheel 11 by controlling the forward and reverse rotation and shutdown of the motor 2 17.
