Description

Technical Field

[0001] The present invention relates to the technical field of surface finishing of elevator wheels, and specifically to a device and process for surface finishing of elevator wheels. Background Technique

[0002] Elevator wheels mainly include traction wheels and deflecting sheaves, which play crucial roles in the elevator system. The traction wheel is a key component in the elevator system and is usually installed on a rigid track in the elevator shaft or between floors. Its main function is to transmit the traction power through the friction between the traction steel wire rope and the rope groove on the traction wheel rim, thereby driving the up and down movement of the elevator car and the counterweight. After the elevator wheel is processed, there will be some burrs on its surface. The existence of burrs will affect the safety of elevator wheel operation. After the elevator wheel is processed, the surface needs to be polished. When using a polishing device to polish the elevator wheel, the operator needs to hold the elevator wheel by hand to polish it. The operator needs to manually place the elevator wheel at the polishing end of the polishing device to polish it. During the polishing process, it is necessary to continuously adjust the polishing position of the elevator wheel, resulting in a relatively large labor intensity for the operator, and the sparks generated during polishing are likely to scald the operator.

One end of the hose away from the spraying frame penetrates through the cooling box and extends into the cooling box. The top of the protective frame extends above the processing frame.

[0013] Further, a process of a surface finishing device for an elevator wheel includes the following steps: S1: When the elastic frame moves downward, it will push the spherical plate to slide inside the cylindrical groove. The push plate is limited by the clamping plate. When the spherical plate moves downward, the bottom of the push plate will move away from each other due to the limitation of the clamping plate. At this time, the push plate will push the clamping plate to move towards the outer end of the sliding hole and squeeze and fix the elevator wheel. S2: When the bottom of the inclined plate moves downward, the top of the inclined plate will incline towards one end of the lifting ring. When the inclined plate inclines, it will push the grinding block to move through the connection between the bent plate and the sliding rod, and push the grinding block to contact the surface of the elevator wheel. S3: When the force-bearing plate moves downward, it pushes the telescopic frame to move towards the surface of the elevator wheel through the round rod. When the inclined surface grinding plates contact the upper and lower ends of the elevator wheel, they will move away from each other due to the pressure. At this time, the inclined surface grinding plates will contact the upper and lower ends of the elevator wheel and use the elasticity of the elastic plate to squeeze it. S4: The water pump will pump the coolant inside the cooling box into the hose. The hose transports the coolant to the inside of the spraying frame. At this time, the coolant can be sprayed on the grinding part of the elevator wheel through the spraying frame, avoiding the high temperature of the elevator wheel during grinding.

[0014] The present invention has the following beneficial effects: After the elevator wheel is placed on the surface of the positioning column in the present invention, the elevator wheel will slide downward and contact the top of the support plate. At this time, the electric push rod is activated to move downward. When the electric push rod moves downward, it pushes the pressure plate to contact the top of the contact plate and pushes the elastic support frame downward. When the elastic support frame moves downward, it will push the spherical plate to slide inside the cylindrical groove. The push plate is limited by the clamping plate. When the spherical plate moves downward, the bottom of the push plate will move away from each other due to the limitation of the clamping plate. At this time, the push plate will push the clamping plate to move towards the outer end of the sliding hole and squeeze and fix the elevator wheel. The number of clamping plates is set to four. The four clamping plates are used to squeeze and limit the elevator wheel, improving the stability of the elevator wheel during grinding and preventing it from shaking during grinding, which affects the processing accuracy. The elevator wheel can be directly sleeved on the surface of the positioning column, and the electric push rod can be used to squeeze and fix it, improving the convenience of installing the elevator wheel. When the elevator wheel needs to be disassembled, the electric push rod is activated to move upward and separate from the contact plate, and the pressure on the clamping plate will disappear. At this time, the elevator wheel can be easily taken out without the operator adjusting it.

[0015] When the pressure plate moves downward in the present invention, it pushes the lifting ring downward through the elastic extrusion frame. When the lifting ring moves downward, it pushes the bottom of the inclined plate downward. Since the bent plate limits the bottom of the inclined plate, when the bottom of the inclined plate moves downward, the top of the inclined plate will tilt towards one end of the lifting ring. When the inclined plate tilts, it will push the grinding block to move through the connection between the bent plate and the sliding rod, and the grinding block will be pushed to contact the surface of the elevator wheel. After the grinding block contacts the elevator wheel, the power device is activated to drive the rotating rod to rotate. When the rotating rod rotates, it drives the positioning column to rotate through the concave hole plate. At this time, the positioning column will drive the elevator wheel to rotate on the surface of the grinding block through the clamping plate, and the surface of the elevator wheel is circumferentially ground by the grinding block without adjusting its angle during grinding, improving the convenience of grinding the elevator wheel. At the same time, when the lifting ring moves downward, it will pull the stress plate downward through the synchronous plate. When the stress plate moves downward, it pushes the telescopic frame towards the surface of the elevator wheel through the round rod. When the inclined surface grinding plate contacts the upper and lower ends of the elevator wheel, it will move away from each other due to the pressure. At this time, the inclined surface grinding plate will contact the upper and lower ends of the elevator wheel and squeeze it using the elasticity of the elastic plate. When the elevator wheel rotates, the inclined surface grinding plate will grind its upper and lower ends, preventing burrs from remaining at the ends of the elevator wheel and affecting its production accuracy. When the elastic extrusion frame moves upward, the elastic extrusion frame will push the grinding block and the inclined surface grinding plate away from the surface of the elevator wheel, improving the convenience of finishing the elevator wheel.

[0016] When the present invention performs fine grinding on the elevator wheel, the water pump is started to operate. The water pump will pump the coolant inside the cooling tank into the inside of the hose, and the hose will transmit the coolant to the inside of the spraying rack. At this time, the coolant can be sprayed on the grinding part of the elevator wheel through the spraying rack, avoiding the high temperature of the elevator wheel during grinding. When the coolant flows downward, it will flow into the inside of the circular groove. At the same time, the coolant will carry the waste chips after grinding into the inside of the circular groove for storage. The coolant will enter the inside of the cooling tank through the sieve holes for recycling, while the waste chips will be stored in the circular groove for centralized treatment. A protective rack is provided on the surface of the processing rack to intercept the coolant to avoid waste.

[0017] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] A process for the surface finishing device of an elevator wheel includes the following steps: S1: When the elastic frame 23 moves downward, it will push the spherical ball plate 26 to slide inside the cylindrical groove 27. The push plate 28 is limited by the clamping plate 21. When the spherical ball plate 26 moves downward, the bottom of the push plate 28 will move away from each other due to the limitation of the clamping plate 21. At this time, the push plate 28 will push the clamping plate 21 to move towards the outer end of the sliding hole 22 and squeeze and fix the elevator wheel 25; S2: When the bottom of the inclined plate 47 moves downward, the top of the inclined plate 47 will incline towards one end of the lifting ring 43. When the inclined plate 47 inclines, it will push the grinding block 41 to move through the connection of the bent plate 42 and the sliding rod 45, and push the grinding block 41 to contact the surface of the elevator wheel 25; S3: When the force-bearing plate 52 moves downward, it pushes the telescopic frame 50 to move towards the surface of the elevator wheel 25 through the round rod 49. When the inclined surface grinding plate 51 contacts the upper and lower ends of the elevator wheel 25, it will move away from each other due to the pressure. At this time, the inclined surface grinding plate 51 will contact the upper and lower ends of the elevator wheel 25 and squeeze it using the elasticity of the elastic plate 53; S4: The water pump 65 will pump the coolant inside the cooling tank 64 into the hose 62. The hose 62 transmits the coolant to the inside of the spraying frame 61. At this time, the coolant can be sprayed on the grinding area of the elevator wheel 25 through the spraying frame 61 to prevent the temperature of the elevator wheel 25 from being too high during grinding.

[0032] During use, after placing the elevator wheel 25 on the surface of the positioning post 20, the elevator wheel 25 will slide downward and contact the top of the support plate 30. At this time, start the electric push rod 5 to move downward. When the electric push rod 5 moves downward, it pushes the pressure plate 6 to contact the top of the contact plate 24 and pushes the elastic frame 23 downward. When the elastic frame 23 moves downward, it will push the spherical plate 26 to slide inside the cylindrical groove 27. The push plate 28 is limited by the clamping plate 21. When the spherical plate 26 moves downward, the bottom of the push plate 28 will move away from each other due to the limitation of the clamping plate 21. At this time, the push plate 28 will push the clamping plate 21 to move toward the outer end of the sliding hole 22 and squeeze and fix the elevator wheel 25. The number of clamping plates 21 is set to four. The four clamping plates 21 are used to squeeze and limit the elevator wheel 25, improving the stability of the elevator wheel 25 during grinding and avoiding shaking during grinding, which may affect the processing accuracy. The elevator wheel 25 can be directly sleeved on the surface of the positioning post 20, and the electric push rod 5 can be used to squeeze and fix it, improving the convenience of installing the elevator wheel 25. When it is necessary to disassemble the elevator wheel 25, start the electric push rod 5 to move upward and separate from the contact plate 24, and the pressure on the clamping plate 21 will disappear. At this time, the elevator wheel 25 can be easily taken out without the operator adjusting it. When the pressure plate 6 moves downward, it pushes the lifting ring 43 downward through the elastic extrusion frame 40. When the lifting ring 43 moves downward, it pushes the bottom of the inclined plate 47 downward. Since the bent plate 42 limits the bottom of the inclined plate 47, when the bottom of the inclined plate 47 moves downward, the top of the inclined plate 47 will tilt toward one end of the lifting ring 43. When the inclined plate 47 tilts, it will push the grinding block 41 to move through the connection between the bent plate 42 and the sliding rod 45, and push the grinding block 41 to contact the surface of the elevator wheel 25. After the grinding block 41 contacts the elevator wheel 25, start the power device 9 to drive the rotating rod 8 to rotate. When the rotating rod 8 rotates, it drives the positioning post 20 to rotate through the concave hole plate 29. At this time, the positioning post 20 will drive the elevator wheel 25 to rotate on the surface of the grinding block 41 through the clamping plate 21, and use the grinding block 41 to perform circumferential grinding on the surface of the elevator wheel 25 without adjusting its angle during grinding, improving the convenience of the elevator wheel 25 during grinding operations. At the same time, when the lifting ring 43 moves downward, it will pull the stress plate 52 downward through the synchronous plate 48. When the stress plate 52 moves downward, it will push the telescopic frame 50 to move toward the surface of the elevator wheel 25 through the round rod 49. When the inclined surface grinding plate 51 contacts the upper and lower ends of the elevator wheel 25, it will move away from each other due to the pressure. At this time, the inclined surface grinding plate 51 will contact the upper and lower ends of the elevator wheel 25 and squeeze it using the elasticity of the elastic plate 53. When the elevator wheel 25 rotates, the inclined surface grinding plate 51 will grind its upper and lower ends, avoiding burrs remaining at the ends of the elevator wheel 25, which may affect its production accuracy. When the elastic extrusion frame 40 moves upward, the elastic extrusion frame 40 will push the grinding block 41 and the inclined surface grinding plate 51 to separate from the surface of the elevator wheel 25, improving the convenience of the elevator wheel 25 during finishing processing.When the elevator wheel 25 is polished and finish-machined, the water pump 65 is started to operate. The water pump 65 will pump the coolant inside the cooling tank 64 into the inside of the hose 62. The hose 62 transmits the coolant to the inside of the spraying rack 61. At this time, the coolant can be sprayed on the polishing area of the elevator wheel 25 through the spraying rack 61, so as to avoid the high temperature of the elevator wheel 25 during polishing. When the coolant flows downward, it will flow into the inside of the circular groove 67. At the same time, the coolant will carry the waste chips after polishing into the inside of the circular groove 67 for storage. The coolant will enter the inside of the cooling tank 64 through the sieve holes 66 for recycling, while the waste chips will be stored in the circular groove 67 for centralized treatment. A protective rack 63 is arranged on the surface of the processing rack 3 to intercept the coolant by using the protective rack 63 to avoid waste.
