Description

Technical Field

[0001] The invention discloses a rotary wheel processing grinder, belonging to the technical field of grinding processing. Background Art

[0002] The basic system of the spinning machine consists of six systems: mechanical, hydraulic, electronic control, numerical control, heating and cooling. The mechanical structure consists of four basic parts: bed, spindle box, tailstock, and rotary wheel frame. The hydraulic system includes hydraulic motor, hydraulic profiling, feed mechanism adjustment, and tailstock pressure regulation and pressure relief fuse. The equipment is available in two types: hydraulic automatic and manual. It can be applied to the one-step spinning of stainless steel, aluminum and other metals.

DETAILED DESCRIPTION

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] like Figures 1-10As shown, a rotary wheel processing grinder includes a workbench 1, a rotating table 18, a driving assembly and a grinding mechanism. The rotating table 18 is rotatably mounted on the workbench 1, and four mounting tables 2 with equal angles are rotatably mounted on the rotating table 18. The driving assembly is mounted on the workbench 1 and is used to drive the rotating table 18 to rotate. The rotating table 18 is provided with a first power assembly for driving the mounting table 2 to rotate. The first power assembly includes a first motor 23, a driving pulley 30, a driven pulley 20 and a belt 31. The first motor 23 is mounted on the rotating table 18, the driving pulley 30 is fixed on the first motor 23, four driven pulleys 20 are provided, and are rotatably mounted below the rotating table 18 corresponding to the mounting table 2 through a first mounting ring 19. The belt 31 1 is set on the outside of the driving pulley 30 and the driven pulley 20, and a transmission member 22 for controlling the power transmission between the two is set between the mounting platform 2 and the driven pulley 20. The grinding mechanism includes a first grinding component 9, a second grinding component 8, a second power component and a third power component. The first grinding component 9 and the second grinding component 8 have the same structure, and both are used to grind the outer circle of the rotating wheel. The first grinding component 9 and the second power component are installed on the outside of one of the mounting platforms 2 corresponding to the workbench 1. The second power component is used to drive the first grinding component 9 to move horizontally, the second grinding component 8 and the second power component are installed on the outside of the other mounting platform 2 corresponding to the workbench 1, and the third power component is used to drive the second grinding component 8 to move vertically.

[0019] The transmission member 22 includes a first transmission rod 38, a second transmission rod 35, a first spring 39 and a second spring 41. One end of the first transmission rod 38 is slidably arranged with the mounting platform 2, and the second transmission rod 35 is slidably arranged with the driven pulley 20. The first spring 39 is sleeved on the outside of the first transmission rod 38, and the first spring 39 applies a force to the first transmission rod 38 close to the second transmission rod 35. The second spring 41 is arranged on the inner side of the second transmission rod 35, and the second spring 41 applies a force to the second transmission rod 35 away from the first transmission rod 38. The ends of the first transmission rod 38 and the second transmission rod 35 close to each other are both provided with angularly distributed protrusions 36, and a groove 40 is provided between two adjacent protrusions 36. The second transmission rod 35 is away from One end of the first transmission rod 38 is a hemispherical structure, and the workbench 1 is provided with an annular ring 21 below the second transmission rod 35. The annular ring 21 has a first horizontal surface 34 and a second horizontal surface 32. The height of the second horizontal surface 32 is higher than the height of the first horizontal surface 34, and a guide slope 33 is provided between the second horizontal surface 32 and the first horizontal surface 34. When the rotating table 18 drives the transmission member 22 and the mounting table 2 to move to a position away from the first grinding assembly 9 and the second grinding assembly 8, one end of the second transmission rod 35 conflicts with the first horizontal surface 34. The protrusions 36 on the first transmission rod 38 and the second transmission rod 35 remain separated under the action of the first spring 39 and the second spring 41. When the rotating table 18 rotates, the second transmission rod 38 As the synchronous rotation is carried out, 35 will slide onto the second horizontal surface 32 through the guide inclined surface 33, so that the second transmission rod 35 slides upward and compresses the first spring 39 and the second spring 41, and finally makes the first transmission rod 38 and the second transmission rod 35 on the protrusion 36 in a state of mutual conflict. When the first motor 23 drives the second transmission rod 35 to rotate through the active pulley 30 and the driven pulley 20, the protrusions 36 on the first transmission rod 38 and the second transmission rod 35 are dislocated and engaged with each other, so that the second transmission rod 35 can drive the first transmission rod 38 and the mounting table 2 to rotate synchronously, and then drive the rotating wheel to rotate, so that the conical surface of the rotating wheel can be ground, so it is close to the first grinding assembly 9 and the second grinding assembly 8. The power transmission between the mounting platform 2 and the driven pulley 20 is smooth, while the power transmission between the mounting platform 2 away from the first grinding assembly 9 and the second grinding assembly 8 and the driven pulley 20 is disconnected. In this way, the first motor 23 can drive the two mounting platforms 2 to rotate while the other two mounting platforms 2 cannot rotate synchronously with the driven pulley 20. It can be achieved that while processing the rotary wheel, the rotary wheel can also be loaded and unloaded, effectively saving waiting time. The rotation power of the four mounting platforms 2 is provided by the first motor 23, which simplifies the structure of the first power component. Pressing plates 37 are provided on both sides of the first spring 39 and the second spring 41. The pressing plates 37 do not rotate with the first transmission rod 38 and the second transmission rod 35.The first spring 39 and the second spring 41 do not directly contact the first transmission rod 38 and the second transmission rod 35, thereby effectively reducing the wear of the first spring 39 and the second spring 41 and ensuring the service life of the springs. The mounting platform 2 rotates on the rotating platform 18 through the second mounting ring 16. The second mounting ring 16 is composed of two semicircular rings, which are fixed to the rotating platform 18 by bolts without affecting the rotation of the mounting platform 2.

[0020] The rotating platform 18 includes a first fixed platform 24 and a second fixed platform 28. At least three support columns 29 are provided on the first fixed platform 24. The second fixed platform 28 is fixedly connected to the first fixed platform 24 by bolts. The mounting platform 2 and the driven pulley 20 are both mounted on the second fixed platform 28. The rotating platform 18 is arranged as a split structure, the middle part of which is a hollow structure, which can facilitate the installation of the driving pulley 30, the driven pulley 20 and the belt 31. When the driving assembly drives the rotating platform 18 to rotate, the first power assembly also rotates synchronously with the rotating platform 18.

[0021] The driving assembly includes a second motor 25 and a driving gear 26. The second motor 25 is installed on the workbench 1. The driving gear 26 is fixed to the output shaft of the second motor 25. The outer periphery of the first fixed table 24 is provided with a plurality of tooth blocks 27 that mesh with the driving gear 26. The workbench 1 is provided with a third mounting ring 17 for mounting the first fixed table 24. The second motor 25 drives the driving gear 26 to rotate, and the rotating table 18 starts to rotate by virtue of the meshing of the tooth blocks 27 and the driving gear 26. In this way, the positions of the four mounting tables 2 can be switched, thereby processing different rotary wheels or loading and unloading the rotary wheels.

[0022] The first grinding assembly 9 includes a mounting seat 46, a rotating block 44, a third motor 47, a fixed shaft 54 ​​and a grinding rod 45. There are two rotating blocks 44, and a rotating shaft 43 is provided on both sides of the rotating block 44. The rotating shaft 43 on one rotating block 44 is rotatably connected to the mounting seat 46. The mounting seat 46 is provided with an arc groove 51 for sliding the rotating shaft 43 on the other rotating block 44. Both ends of the fixed shaft 54 ​​are rotatably connected to the two rotating blocks 44. The third motor 47 is installed on one of the rotating blocks 44, and the output shaft of the third motor 47 is connected to the fixed The grinding rod 45 is detachably mounted on the fixed shaft 54. The mounting seat 46 is provided with a first adjusting device 42 for adjusting the inclination angle of the grinding rod 45 to the horizontal plane. The first adjusting device 42 includes a first swinging rod 55, a second swinging rod 58, an adjusting bolt 60, a fixing nut 57 and an adjusting nut 56. One end of the first swinging rod 55 is rotatably connected to the rotating shaft 43, and the other end is embedded in the second swinging rod 58. One end of the second swinging rod 58 is rotatably mounted on the mounting seat 46, and both the second swinging rod 58 and the first swinging rod 55 are provided with mounting holes. The mounting portion 59 is provided, and one end of the adjusting bolt 60 passes through the two mounting portions 59 and is connected to the fixing nut 57. The adjusting nut 56 is connected to the adjusting bolt 60, and the adjusting nut 56 is located between the two mounting portions 59. An angle scale 53 is also provided on the mounting seat 46. An indicator rod 52 is installed between the rotating shaft 43 on the same side of the two rotating blocks 44. The grinding rod 45 can be disassembled and replaced by the two rotating blocks 44 and the fixed shaft 54, and the grinding rod 45 is driven to rotate by the third motor 47, so that the rotary wheel can be ground. In the actual processing process, the two sides of the rotary wheel are The inclination angles of the cone surfaces are different. In order to make the inclination angle of the grinding rod 45 consistent with the angle of the cone surface, by rotating the relative positions of the fixing nut 57 and the adjusting nut 56, the overall length of the first swing rod 55 and the second swing rod 58 is adjusted, so that the rotating shaft 43 on one of the rotating blocks 44 slides in the arc groove 51, thereby causing the grinding rod 45 to rotate, and the indicator rod 52 rotates synchronously with the rotating shaft 43. By observing that the indicator rod 52 points to different scale positions on the angle scale 53, the inclination angle of the grinding rod 45 can be adjusted.

[0023] The first grinding assembly 9 also includes a second adjusting device 10, which includes a base 48, a first screw 49 and a first guide rod 50. The mounting seat 46 is slidably set on the base 48. Both ends of the first guide rod 50 and the first screw 49 are rotatably connected to the base 48. The middle part of the first screw 49 is threadedly connected to the mounting seat 46, and one end of the first screw 49 has an inner hexagonal groove. The first guide rod 50 and the mounting seat 46 are slidably set. By rotating the first screw 49, the mounting seat 46 slides along the first guide rod 50, so that the grinding rod 45 can maintain synchronous movement, thereby changing the contact position of the grinding rod 45 and the rotating wheel, thereby improving the utilization rate of the grinding rod 45.

[0024] The second power assembly includes a first slide 11, a second screw 14 and a fourth motor 13. A mounting block 12 is provided on the workbench 1. Both ends of the second screw 14 are rotatably connected to the workbench 1 and the mounting block 12 respectively. The first slide 11 is threadedly connected to the second screw 14. Guide blocks 15 are provided on both sides of the workbench 1 corresponding to the first slide 11. The output shaft of the fourth motor 13 is fixedly connected to the second screw 14. The first grinding assembly 9 is installed on the first slide 11. The second screw 14 is driven to rotate by the fourth motor 13, so that the second screw 14 drives the first slide 11 to slide along the guide block 15, so that the grinding rod 45 contacts the rotating wheel. At the same time, the third motor 47 drives the grinding rod 45 to rotate. The rotation direction of the grinding rod 45 is opposite to that of the rotating wheel, so that the conical surface of the rotating wheel can be ground smoothly.

[0025] The third driving force assembly includes a second slide 4, a fixed frame 3, a second guide rod 7, a third screw 5 and a fifth motor 6. The fixed frame 3 is fixed on the workbench 1, and both ends of the second guide rod 7 and the third screw 5 are rotatably connected to the fixed frame 3 and the workbench 1 respectively. The fifth motor 6 is installed on the fixed frame 3, and the output shaft of the fifth motor 6 is fixedly connected to the third screw 5. The second slide 4 is threadedly connected to the third screw 5, and the second slide 4 is slidably connected to the second guide rod 7. The second grinding assembly 8 is installed on the second slide. The third screw 5 is driven by the fifth motor 6 to rotate, so that the third screw 5 drives the second slide 4 to move vertically along the second guide rod 7, so that the grinding rod 45 approaches the rotating wheel from top to bottom and grinds the rotating wheel. The grinding rods 45 in the first grinding assembly 9 and the second grinding assembly 8 have different inclination angles. The two can grind the two conical surfaces of the rotating wheel separately. There is no need to clamp the rotating wheel for the second time, and there is no need to repeatedly adjust the inclination angle of the grinding rod 45, which is easy to operate.

[0026] Working principle: The rotary wheel is fixed to the mounting table 2 by bolts, and then the driving assembly drives the rotating table 18 to rotate 90 degrees, so that the mounting table 2 rotates with the rotating table 18 to a position close to the first grinding assembly 9. During this process, one end of the second transmission rod 35 moves from the first horizontal plane 34 to the second horizontal plane 32, so that the second transmission rod 35 moves upward for a distance and slides relative to the driven pulley 20 until the protrusion 36 on the second transmission rod 35 conflicts with the protrusion 36 on the first transmission rod 38. When the first motor 23 drives the driven pulley 20 to rotate by relying on the active pulley 30 and the belt 31, the second transmission rod 35 rotates synchronously with the driven pulley 20, so that the protrusion 36 on the second transmission rod 35 and the first transmission rod 38 are misaligned, and the second transmission rod 35 and the first transmission rod The protrusion 36 on 38 is engaged with the groove 40, so that the second transmission rod 35 can drive the first transmission rod 38 and the mounting platform 2 to rotate synchronously, so that the rotating wheel can rotate together, and then the second power assembly drives the grinding rod 45 on the first grinding assembly 9 to contact the rotating wheel. Driven by the third motor 47, the grinding rod 45 begins to grind one of the conical surfaces of the rotating wheel. After one of the conical surfaces is ground, the driving assembly drives the rotating table 18 to continue to rotate 90°, and relies on the second grinding assembly 8 and the third power assembly to grind the other conical surface of the rotating wheel. In this way, the processing of two conical surfaces of the rotating wheel with different inclination angles can be achieved by clamping once. The operation is simple and convenient. While the rotating wheel is being ground, the rotating wheel can also be loaded and unloaded, which effectively improves the processing efficiency of the rotating wheel.
