Description

Technical Field

[0001] This invention relates to the field of grinding equipment, and more particularly to an internal grinding machine for gear processing. Background Technology

[0002] A gear is a mechanical component with teeth on its rim that continuously meshes to transmit motion and power. It is a mechanical component with a continuous toothed structure on its edge, usually used in pairs, to transmit motion and power through the meshing of its teeth. Its basic principle is to use gear combinations with different numbers of teeth to change speed, torque, or direction of rotation. Common types include spur gears, helical gears, bevel gears, and worm gears. Gears are widely used in various mechanical transmission systems, such as automotive gearboxes, machine tools, watches, and industrial robots, and are core components for achieving precise transmission ratios and efficient energy transfer.

[0003] In the field of gear machining, the accuracy of the inner bore is a key factor affecting the gear transmission performance. Internal grinding machines are commonly used in the finishing of gear inner rings. However, the diameter of the grinding components' orbital trajectory on current internal grinding machines is usually fixed or has a limited adjustment range, making it difficult to flexibly adapt to the machining needs of gear inner rings with different inner diameters, resulting in low equipment versatility. Furthermore, the clamping mechanisms are mostly designed for gears with specific outer diameters or lengths, exhibiting poor adaptability to clamping gears of different specifications, easily leading to problems such as unstable clamping and positioning deviations, affecting grinding accuracy and surface quality.

[0043] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0044] Figures 1 to 15 The diagram shown is a structural schematic of an embodiment of the internal grinding machine for gear processing of the present invention.

[0045] An internal grinding machine for gear processing includes a grinding unit and a workpiece fixing unit. Both the grinding unit and the workpiece fixing unit are mounted on the top of the machine tool support frame 1. The grinding unit is used to grind the inner circle of the gear, and the workpiece fixing unit is used to disassemble and fix the gear. The grinding unit includes a grinding component 2 and a fixed ring plate 3. The grinding component 2 is connected to the execution end of the position control component 4.

Two symmetrically distributed rotating support assemblies 13 are connected to the outer side of the intermediate ring plate 9. The outer side of the intermediate ring plate 9 is connected to the execution end of the rotating drive assembly 14.

[0047] The feed component 6 controls the lateral position of the grinding component 2, which extends into the inner ring of the gear and rotates on its own axis. The rotating component 5 drives the grinding component 2 to revolve around the gear, thus grinding the inner ring of the gear. The position control component 4 can adjust the longitudinal position of the grinding component 2, thereby adjusting the diameter of the revolving trajectory of the grinding component 2, and thus grinding the inner ring of gears with different inner diameters. The main clamping assembly 11 can clamp and fix gears of different diameters, and the rotation drive assembly 14 can drive the auxiliary clamping plate 10 and other structures to rotate, thereby driving the gear to rotate. The rotation direction is opposite to the revolution direction of the grinding assembly 2, which can improve the grinding efficiency of the gear. At the same time, the main clamping assemblies 11 on both sides can assist in clamping and fixing the gear, improve the stability of the gear fixing, and thus improve the grinding accuracy of the inner ring of the gear. Furthermore, the positions of the two auxiliary clamping plates 10 can be adjusted by the main clamping assembly 11, so that the two auxiliary clamping plates 10 can move towards each other or away from each other, thereby adjusting the distance between the two auxiliary clamping plates 10. This allows the main clamping assembly 11 and the two auxiliary clamping plates 10 to clamp and fix gears of different lengths, improving the applicability of the workpiece fixing unit and increasing the practicality of the internal grinding machine.

[0048] The grinding assembly 2 includes a grinding power source 21, the output end of which is connected to a rotating shaft 22, and the end of the rotating shaft 22 away from the grinding power source 21 is detachably connected to a grinding head 23.

Multiple side bevel gears 45 arranged in a ring array are meshed on the side of the central bevel gear 44. One side of the side bevel gear 45 is connected to one end of the control threaded shaft 46. The end of the control threaded shaft 46 away from the side bevel gear 45 is rotatably connected to the inner side of the fixed ring plate 3. The control threaded shaft 46 is threadedly connected to a movable plate 47. One of the movable plates 47 is connected to a grinding power source 21 on one side, and the other movable plates 47 are connected to counterweights 48 on both sides.

[0053] The lateral distance of the grinding component 2 is adjusted by the position control component 4, so that the grinding component 2 can grind gear rings with different inner diameters.

[0056] Two fixed guide posts 42 are provided on both sides of the control threaded shaft 46, and the surface of the fixed guide posts 42 is slidably connected to the movable plate 47.

[0057] In use, based on the diameter of the inner ring of the gear, the control power source 43 drives the central bevel gear 44 to rotate, thereby simultaneously driving multiple side bevel gears 45 to rotate. When the side bevel gears 45 rotate, they drive the corresponding control threaded shaft 46 to rotate, which in turn drives the corresponding moving plate 47 to move along the fixed guide post 42, thereby driving the grinding assembly 2 to move in the same direction. The position of the grinding assembly 2 is adjusted, thereby controlling the diameter of the revolution trajectory of the grinding assembly 2.

[0058] The rotating assembly 5 includes a mounting plate 51, and adjusting plates 53 are provided on both the upper and lower sides of the fixed ring plate 3. Multiple connecting strips 52 are connected to one side of the mounting plate 51, and the ends of the connecting strips 52 away from the mounting plate 51 are respectively connected to two adjusting plates 53.

One side of the plate is connected to the output end of the rotating power source 54, and the end of the cylinder away from the plate is connected to one side of the fixed housing 41.

[0062] In use, the rotary power source 54 drives the rotary connecting frame 55 to rotate, thereby driving the fixed housing 41 to rotate, which in turn drives the fixed guide column 42 to rotate, thereby driving the fixed ring plate 3 to rotate. When the fixed ring plate 3 rotates, it drives the rotary track ring 56 to rotate around the fixed track shell 57.

[0063] When the fixed guide column 42 and other structures rotate, they drive the moving plate 47 to rotate, which in turn drives the grinding component 2 to rotate, so that the grinding component 2 can revolve around the inner ring of the gear and perform grinding processing on the inner ring of the gear.

[0064] The feed assembly 6 includes two feed threaded shafts 61, which are symmetrically distributed vertically. The two ends of the two feed threaded shafts 61 are rotatably connected to the two sides of the mounting frame 8. The surface of the feed thread shaft 61 is threaded to the adjusting plate 53, and one end of each of the two feed thread shafts 61 is connected to the synchronous drive assembly 7.

[0065] The lateral position of structures such as the rotating component 5 and the grinding component 2 is adjusted by the feed component 6.

[0066] Multiple anti-deviation columns 62 are connected to the inner wall of the mounting frame 8, and the surface of the anti-deviation column 62 is slidably connected to the adjusting plate 53.

[0068] The synchronous drive assembly 7 includes a synchronous power source 71, the output end of which is connected to a drive shaft 72. Two bevel gear transmission parts 73 are connected to the surface of the drive shaft 72, which are distributed vertically. The two bevel gear transmission parts 73 are respectively connected to one end of two feed thread shafts 61.

[0069] The synchronous drive assembly 7 provides driving force to both feed thread shafts 61 simultaneously.

[0070] The synchronous power source 71 is installed on the top of the mounting bracket, which is connected to the top of the machine tool support frame 1.

[0071] Both the drive shaft 72 and the bevel gear drive unit 73 are located inside the protective housing 74, and one side of the protective housing 74 is connected to the mounting frame 8.

[0072] The surface of the drive shaft 72 is rotatably connected to the bottom surface of the protective housing 74, and the top end of the drive shaft 72 is rotatably connected to the inner wall of the top surface of the protective housing 74.

[0073] The bevel gear transmission unit 73 consists of two meshing bevel gears, one of which is connected to the transmission shaft 72, and the other is connected to one end of the feed thread shaft 61.

[0074] The main clamping assembly 11 includes a clamping housing 111, a main clamping plate 115 connected to one side of the clamping housing 111, and the output end of the telescopic device 12 connected to the other side of the clamping housing 111. The telescopic device 12 is connected to the outside of the intermediate ring plate 9. A clamping power source 112 is installed in the inner cavity of the clamping housing 111. The output end of the clamping power source 112 is connected to a central gear 113. Movable racks 114 are meshed on both sides of the central gear 113. A secondary clamping plate 10 is connected to the opposite ends of the two movable racks 114.

[0075] The positions of the two auxiliary clamping plates 10 are adjusted synchronously by the main clamping assembly 11, and the gear is clamped and fixed by the multiple auxiliary clamping plates 10 and the main clamping assembly 11.

[0076] The surface of the movable rack 114 is slidably connected to the side of the clamping housing 111.

[0077] The movable rack 114 has an anti-deviation opening, and multiple anti-deviation strips 116 are connected to the inner wall of the clamping housing 111. The anti-deviation strips 116 are slidably connected to the movable rack 114 through the anti-deviation opening.

[0078] In use, the telescopic device 12 drives the clamping housing 111 to move, causing the clamping housing 111 to move toward or away from the center of the intermediate ring plate 9, thereby driving the clamping housing 111, the moving rack 114, the auxiliary clamping plate 10 and the main clamping plate 115 to move in the same direction, and using multiple main clamping plates 115 to clamp and fix the gear.

[0079] Based on the length of the gear, the clamping power source 112 drives the central gear 113 to rotate. When the central gear 113 rotates, it drives the moving racks 114 on both sides to move towards or away from each other along the anti-deviation strip 116, thereby driving the auxiliary clamping plates 10 to move in the same direction. The positions of the auxiliary clamping plates 10 on both sides are adjusted synchronously, so that the longer gears can still be clamped stably, improving the accuracy of grinding long gears.

[0080] Both sides of the intermediate ring plate 9 are provided with follower rings 15. One side of the follower ring 15 is connected to a plurality of sliding columns 16 arranged in a ring array.

[0081] Multiple telescopic plates 18 arranged in a ring array are connected to the inner side of the follower ring 15. The end of the telescopic plate 18 away from the follower ring 15 is connected to the side of the moving rack 114.

[0082] The telescopic plate 18 is a multi-section interlocking telescopic structure, which allows the telescopic plate 18 to extend and retract as the moving rack 114 moves.

[0083] When the moving rack 114 moves longitudinally, it drives the secondary clamping plate 10 to move in the same direction, which in turn drives the telescopic plate 18 to extend and retract.

[0084] When the moving rack 114 moves laterally, it drives the secondary clamping plate 10 and the telescopic plate 18 to move in the same direction. When the telescopic plate 18 moves, it drives the follower ring 15 to move in the same direction, which in turn drives the sliding column 16 to move in the same direction, thus limiting the movement trajectory of the secondary clamping plate 10 and other structures. When the sliding column 16 moves, it drives the anti-deviation ring 17 to move in the same direction, preventing the sliding column 16 from slipping off the middle ring plate 9.

[0085] The rotating support assembly 13 includes a follower track ring 131. Two symmetrically distributed follower track rings 131 are connected to the outer side of the middle ring plate 9. The follower track rings 131 are slidably connected to the inner wall of the support track shell 132. The bottom of the support track shell 132 is connected to the top of the protective frame 133. The protective frame 133 is connected to the top of the machine tool support frame 1.

[0086] The intermediate ring plate 9 is rotated and supported by the rotating support assembly 13, making the intermediate ring plate 9 more stable when rotating.

[0087] The rotation drive assembly 14 includes a fixed gear ring 141. Two symmetrically distributed fixed gear rings 141 are connected to the surface of the intermediate ring plate 9. Two symmetrically distributed transmission gears 142 are meshed with the side of the fixed gear ring 141. A drive gear 143 is meshed with the lower side of the transmission gear 142. The transmission gear 142 and the drive gear 143 are respectively connected to the rotating support shaft 144, and the end face of the rotating support shaft 144 is rotatably connected to both sides of the protective frame 133.

[0088] The rotation drive assembly 14 drives the intermediate ring plate 9 and other structures to rotate, thereby driving the gear to rotate.
