Description

Technical Field

[0001] The present invention relates to the technical field of gear processing, and particularly to a stable gear modification device for the processing of reducer gears. Background Art

[0002] A reducer, also known as a speed reducer, realizes the adjustment of rotational speed through the meshing transmission between different specifications of gears inside the reducer. It is installed between the prime mover and the working machine, and its main function is to reduce the rotational speed and increase the torque, so as to meet the requirements of the working machine in terms of low speed and high torque. During the processing of reducer gears, in order to improve the accuracy and surface quality of the gears, modification processing is usually required to avoid burrs between external teeth and other factors affecting the stability during meshing. Grinding modification is a common tooth profile modification method, and tools such as grinding wheels or grinding belts are usually used. The surfaces of these tools have certain grinding particles, which can perform micro grinding on the gear tooth surfaces.

[0003] In the prior art, during the grinding process of reducer gears, generally, the angle of the grinding wheel is adjusted through an adjustment system to make it match the tooth angle of the gear, and then the grinding wheel grinds the groove between the teeth. There is a lack of grinding on the circumferential outer surface of the gear, and the function is relatively single. When there are burrs or the outer surface is rough on the gear, the helical gear needs to be removed, and then its outer surface is ground and modified separately, which increases additional disassembly, installation, and clamping work, consumes more time and labor, reduces the production smoothness, and affects the work efficiency.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. When the present invention is in use, the gear is sleeved on the clamping rod disc, and the pressing screw rod is screwed into the top of the fixed shaft to clamp and fix the gear. The angle adjustment system is started to adjust the angle of the grinding disc, and the transverse feed system is started to drive the grinding disc into the groove between the teeth. At the same time, the grinding component is driven to move together, so that the diamond-coated grinding plate contacts the outer surface of the gear. The vertical feed system and the grinding motor are started. The grinding motor drives the grinding disc to rotate, and the vertical feed system drives the grinding disc and the diamond-coated grinding plate to move up and down together to grind and shape the teeth and the outer surface of the gear. With the cooperation of the grinding component and the grinding component, two parts can be processed simultaneously, more grinding work can be completed in the same time, the overall processing time can be effectively shortened, it is not necessary to remove the gear and grind the outer surface separately, the workload of disassembly and installation is reduced, and the work efficiency is improved.

[0020] 2. When the present invention is in use, the forward and reverse motor is started to drive the rotating rod, the rotating plate and the U-shaped frame to rotate, so that the two grinding wheels rotate to the top and bottom of the gear. At the same time, the angle sensor detects the rotation angle. When the rotation angle meets the set working threshold, the PLC controller will control the forward and reverse motor to shut down. Then, two electric push rods are started to push the two T-shaped sleeves, T-shaped blocks and gear rollers to move relatively, so that the two grinding wheels contact the top and bottom of the gear. The double-shaft motor is started to drive the rotating shaft, the driving gear, the chain, the driven gear and the two I-shaped blocks to rotate, and the two grinding wheels are driven to rotate together by the two gear rollers to grind the edges at the top and bottom of the gear. The grinding component, the grinding component and the upper and lower grinding components can either work together simultaneously or work locally separately, which is more flexible and has rich functions.

[0021] 3. When the present invention is in use, the electromagnet is turned off, the magnetism disappears, the pull ring is pulled, and the pushing rod, the tapered block, the fixed rod and the circular magnet are driven to move through the limiting rod, so that the circular magnet returns to the movable hole. As the tapered block moves, the two adjusting rollers roll downward in the two inclined grooves respectively, and the return spring starts to rebound, so that the distance between the two adjusting rollers gradually becomes shorter, and the ejector rod is driven to move into the reinforcing rod, and the triangular clamping block is pulled into the triangular hole, and then the reinforcing rod can be removed separately, which is convenient to remove the grinding component and use it on other shaping equipment. According to the cooperation of the triangular mark and the indication mark, the reinforcing rod can be moved to other positions, and then the pull ring is pushed to move in the reverse direction, so that the circular magnet is magnetically attracted to the electromagnet, and the triangular clamping block is pushed into the triangular groove again from the triangular hole to fix the reinforcing rod, so as to achieve the effect of adjusting the position of the diamond-coated grinding plate and adapting to gears of different sizes.

The top of the bottom plate 108 is installed with a protective cover 109 through bolts. A rotating motor 110 is arranged inside the protective cover 109. The output end of the rotating motor 110 is fixedly installed with a fixed shaft 111. A clamping rod disc 112 is fixedly installed on the outer surface of the fixed shaft 111. A pressing screw rod 113 is threadedly embedded at the top end of the fixed shaft 111. The top end of the fixed shaft 111 movably penetrates through the top of the protective cover 109. The bottom of the rotating motor 110 is fixedly installed on the top of the bottom plate 108.,

[0036] In this embodiment, during use, the transverse feed system 103, the vertical feed system 104, the angle adjustment system 105, the grinding motor 106, the rotating motor 110, the electromagnet 222, the forward and reverse motor 302, the angle sensor 304, the dual-axis motor 307, the electric push rod 316 and the PLC controller 102 are electrically connected. The structure of the clamping rod disc 112 is as Figure 3As shown, there are five vertical clamping posts. The gear to be ground is sleeved on the fixed shaft 111 and placed on the clamping rod disc 112, so that the clamping posts on the clamping rod disc 112 are inserted into the circular holes of the gear. Then, the pressing screw 113 is screwed into the top of the fixed shaft 111 to fix the gear on the clamping rod disc 112 and clamp the gear. The transverse feed system 103 is used to control the transverse movement of the vertical feed system 104. The vertical feed system 104 is used to control the vertical feed movement of the grinding disc 107 and the diamond-coated grinding plate 205 during the grinding process. The angle adjustment system 105 is used to adjust the relative angle between the grinding disc 107 and the gear to meet the grinding requirements of different helix angles, ensuring that the grinding disc 107 can contact the grooves between the gear teeth at an appropriate angle to achieve uniform and precise grinding. After the gear is installed and fixed, the angle adjustment system 105 is started to adjust the angles of the grinding motor 106 and the grinding disc 107 so that the angle of the grinding disc 107 matches the angle of the inclined teeth on the outer surface of the gear. Then, the transverse feed system 103 is started to drive the vertical feed system 104, the angle adjustment system 105, and the grinding motor 106 to move towards the gear, so that the grinding disc 107 enters the groove on the outer surface of the gear. While the angle adjustment system 105 moves, it drives the grinding component 2 to move together, so that the inner wall of the diamond-coated grinding plate 205 contacts the circular outer surface of the gear. The vertical feed system 104 and the grinding motor 106 are started. The grinding motor 106 drives the grinding disc 107 to rotate, and the vertical feed system 104 drives the angle adjustment system 105 to move up and down, driving the grinding disc 107 and the diamond-coated grinding plate 205 to move up and down together. The grinding disc 107 moves up and down in the groove of the gear to grind and modify the teeth, and at the same time, the diamond-coated grinding plate 205 moves up and down on the outer surface of the gear to grind and modify the circular outer surface, making the outer surface of the gear smoother and more regular, which is beneficial to accurately controlling the outer diameter size of the gear and coordinating with the grinding between the teeth, improving the shape accuracy and position accuracy of the whole gear. With the cooperation of the grinding component 1 and the grinding component 2, the machining of two parts can be carried out simultaneously, more grinding work can be completed in the same time, the overall machining time can be effectively shortened, there is no need to remove the gear and grind the outer surface separately, the workload of disassembly and installation is reduced, and the work efficiency is improved. When the grinding of one tooth groove is completed, the transverse feed system 103 drives the vertical feed system 104 to move in the reverse direction, so that the grinding disc 107 leaves between the teeth, and the diamond-coated grinding plate 205 separates from the outer surface of the gear. Then, the rotation motor 110 controls the rotation of the fixed shaft 111, driving the clamping rod disc 112 and the clamped gear to rotate, so that the ground teeth rotate away, and the next tooth to be ground rotates over. Under the control of the transverse feed system 103, the grinding disc 107 enters between the rotated teeth again to grind this place, and the diamond-coated grinding plate 205 grinds the outer surface of the gear after rotation.The diamond-coated grinding plate 205 is coated with diamond. Diamond has extremely high hardness and wear resistance, which can remove the material on the outer surface of the gear more quickly. Compared with ordinary grinding materials, it can grind at a higher speed and efficiency, further improving the processing efficiency. It solves the problem that in the grinding process of the reducer gear, generally the grooves between the teeth are ground, and the grinding of the outer circumferential surface of the gear is lacking, and the function is relatively single. When the outer surface of the gear is relatively rough, the helical gear needs to be removed and then its outer surface is ground and shaped separately, which increases extra work, consumes more time and manpower, reduces the production fluency, and affects the work efficiency.

[0037] Embodiment 2: As Figures 1 - 5 shown, the upper and lower grinding assemblies 3 include a fixed frame 301. A positive and negative motor 302 is fixedly installed on the top surface inside the fixed frame 301.

A driven gear 311 is meshed with the inside of each of the two chains 310. An I-shaped block 312 is fixedly installed on the opposite side of each of the two driven gears 311. A gear roller 313 is meshed with the inside of each of the two I-shaped blocks 312. A T-shaped block 314 is fixedly installed on the outer surface of one side of each of the two gear rollers 313. Two mounting frames 315 are fixedly installed on the outer surface of the U-shaped frame 306. An electric push rod 316 is fixedly installed inside each of the two mounting frames 315. A T-shaped sleeve 317 is fixedly installed at one end of each of the two electric push rods 316. A grinding wheel 318 is installed on the outer surface of the other side of each of the two gear rollers 313 through bolts. Rotating holes 319 are opened at the top and bottom of the U-shaped frame 306. The outer surfaces of the two I-shaped blocks 312 are respectively movably embedded in the two rotating holes 319. The rear surface of the fixed frame 301 is fixedly installed on the front surface of the grinding bed 101.

The outer surfaces of the two T-shaped blocks 314 are respectively movably embedded in the two T-shaped sleeves 317. The outer surfaces of the two gear rollers 313 are respectively movably embedded in the two driven gears 311.

[0038] In this embodiment, during use, the grinding assembly 1 drives the grinding disc 107 to contact the groove between the teeth. After the diamond-coated grinding plate 205 contacts the outer surface of the gear, the forward and reverse motor 302 is started. The rotation of the output end of the forward and reverse motor 302 drives the rotating rod 303 to rotate, and the two rotating plates 305 drive the U-shaped frame 306 to rotate around the rotating rod 303, so that the two grinding wheels 318 rotate to the top and bottom of the gear, as Figure 1As shown. Meanwhile, the angle sensor 304 detects the rotation angle of the rotating rod 303 and transmits the detected angle data to the PLC controller 102 for identification and comparison. The threshold value of the angle data is set in advance inside the PLC controller 102. When the rotation angle of the rotating rod 303 meets the set working threshold, the PLC controller 102 will control the forward and reverse motor 302 to turn off, so that the two grinding wheels 318 are respectively located at the edges of the top and bottom of the gear. Then, the two electric push rods 316 are started simultaneously to push the two T-shaped sleeves 317 to move relatively and push the two T-shaped blocks 314 to move relatively, so that the two gear rollers 313 move relatively in the corresponding I-shaped blocks 312 respectively, and further make the two grinding wheels 318 move relatively and contact the top and bottom of the gear. While starting the grinding disc 107 and the diamond-coated grinding plate 205 to work, the double-shaft motor 307 is started. The two output ends of the double-shaft motor 307 drive the two rotating shafts 308 and the two driving gears 309 to rotate together. Under the connection of the two chains 310, the two driven gears 311 and the two I-shaped blocks 312 are driven to rotate together. The gear roller 313 is meshed with the I-shaped block 312. When the I-shaped block 312 rotates, it drives the two gear rollers 313 to rotate together. At the same time, the T-shaped block 314 rotates inside the T-shaped sleeve 317, and further drives the two grinding wheels 318 to rotate together to grind and process the edges of the top and bottom of the gear. With the cooperation of the grinding component 1, the grinding component 2 and the upper and lower grinding component 3, the gear can be ground at multiple points and different positions simultaneously, and the gear can be ground more comprehensively, greatly improving the working efficiency. By removing the grinding component 1, the grinding component 1 can be used alone to grind the teeth of the gear. By driving the grinding disc 107, the grinding component 2 can be used alone to grind the outer surface of the gear. By only starting the upper and lower grinding component 3, the top and bottom of the gear can be ground separately. The grinding component 1, the grinding component 2 and the upper and lower grinding component 3 can not only work together simultaneously, but also work locally alone, which is more flexible and has rich functions. When the transverse feed system 103 drives the grinding disc 107 to move backward and reset, the double-shaft motor 307 is turned off, and the two electric push rods 316 are started again to pull the two T-shaped sleeves 317 and the T-shaped blocks 314 to move backward. The two grinding wheels 318 are driven to leave and separate from the gear by the gear roller 313. Then, the rotating motor 110 drives the clamped gear to rotate. After adjusting the position, the grinding disc 107 enters between the teeth again, and the electric push rod 316 pushes the grinding wheel 318 to contact the gear again for the next grinding process.

A magnetic attraction groove 220 is formed inside the fixing plate 201. Multiple jacking holes 221 are equidistantly formed on the rear surface inside the fixing plate 201. An electromagnet 222 is fixedly installed inside the magnetic attraction groove 220. Two limiting rods 223 are fixedly installed on the outer surface of the other end of the pushing rod 206. Two limiting holes 224 are formed on the outer surface of the reinforcing rod 202. Two triangular marks 225 are fixedly installed on the outer surface of the reinforcing rod 202 near the limiting holes 224. Multiple indicating marks 226 are equidistantly formed on the front surface of the fixing plate 201. A pull ring 227 is movably sleeved on the outer surface of the reinforcing rod 202. The rear surface of the fixing plate 201 is fixedly installed on the front surface of the angle adjustment system 105. The connecting block 204 and the mounting block 203 are connected by a hand-tightening bolt. One end of both of the two return springs 215 is fixedly connected to the inner wall of the reinforcing rod 202. The other end of both of the two return springs 215 is fixedly connected to the outer surface of one side of both of the two circular plates 212 respectively. The outer surfaces of both of the two adjusting rollers 211 are respectively movably embedded inside the two inclined grooves 216. The outer surfaces of both of the two jacking rods 213 are respectively movably embedded inside the two triangular holes 217. The outer surface of the fixing rod 208 is movably embedded inside the movable hole 218. The outer surfaces of both of the two triangular clamping blocks 214 are respectively movably embedded inside two of the triangular grooves 219.

The rear surface of the circular magnet 209 is magnetically connected to the front surface of the electromagnet 222. The outer surfaces of both of the two limiting rods 223 are respectively movably embedded inside the two limiting holes 224. One end of both of the two limiting rods 223 is respectively fixedly installed on both sides inside the pull ring 227.

[0040] In this embodiment, during use, the electromagnet 222 is turned off by the PLC controller 102, causing it to lose power and magnetic attraction. At this time, the magnetic attraction between the circular magnet 209 and the electromagnet 222 disappears. Then, the pull ring 227 is pulled, driving the limit rod 223 to move in the limit hole 224, and driving the push rod 206, the conical block 207, the fixed rod 208, and the circular magnet 209 to move, so that the circular magnet 209 moves out of the magnetic suction groove 220, passes through the jack 221, and returns to the movable hole 218. As shown in the inclined groove 216 Figure 9 As shown, as the conical block 207 moves, the two adjusting rollers 211 are respectively driven to roll downward in the two inclined grooves 216. At this time, the outward thrust received by the adjusting rollers 211 gradually decreases, and the extrusion force received by the compressed return spring 215 gradually becomes smaller, and the return spring 215 begins to rebound, generating a relative thrust on the two circular plates 212. When the adjusting rollers 211 roll from the high position to the low position of the inclined groove 216, under the elastic force of the return spring 215, the distance between the two adjusting rollers 211 gradually becomes shorter. The push rod 213 is driven to move into the inside of the reinforcing rod 202 through the roller frame 210 and the circular plate 212, further driving the triangular latch 214 to move from the triangular groove 219 into the triangular hole 217. At this time, the connection between the reinforcing rod 202 and the fixing plate 201 is lost, and the reinforcing rod 202 can be removed separately, facilitating the removal of the grinding assembly 2 for use on other shaping devices. According to the cooperation of the triangular mark 225 and the indication mark 226, the reinforcing rod 202 can be moved to other positions. Then, the pull ring 227 is pushed to move in the reverse direction, and the conical block 207 and the fixed rod 208 are pushed through the push rod 206, and the circular magnet 209 is pushed from the jack 221 at the corresponding position into the magnetic suction groove 220. The electromagnet 222 is restarted, causing the circular magnet 209 and the electromagnet 222 to be magnetically attracted together to limit the conical block 207. When the conical block 207 moves, the adjusting rollers 211 roll from the low position to the high position inside the inclined groove 216, and at the same time, they receive an outward thrust, causing the two push rods 213 to move outward simultaneously, pushing the triangular latch 214 from the triangular hole 217 into the triangular groove 219 again to fix the reinforcing rod 202, thereby achieving the effect of adjusting the position of the reinforcing rod 202, facilitating the adjustment of the position of the diamond-coated grinding plate 205 to adapt to gears of different sizes.

[0041] The effects and working principle achieved by the entire mechanism are as follows: The gear to be ground is sleeved on the fixed shaft 111 and placed on the clamping rod disc 112, so that the clamping columns on the clamping rod disc 112 are inserted into the circular holes of the gear. Then, the pressing screw 113 is screwed into the top of the fixed shaft 111 to fix the gear on the clamping rod disc 112. Start the angle adjustment system 105 to adjust the angles of the grinding motor 106 and the grinding disc 107 so that the angle of the grinding disc 107 matches the angle of the inclined teeth on the outer surface of the gear. Then, start the transverse feed system 103 to drive the vertical feed system 104, the angle adjustment system 105, and the grinding motor 106 to move towards the gear, so that the grinding disc 107 enters the groove on the outer surface of the gear. When the angle adjustment systemAfter one of the tooth grooves is polished, the transverse feed system 103 drives the vertical feed system 104 to move in the reverse direction, so that the grinding disc 107 moves away from between the teeth, and the diamond-coated grinding plate 205 separates from the outer surface of the gear. Then, the dual-axis motor 307 is turned off, and the two electric push rods 316 are started again to pull the two T-shaped sleeves 317 and T-shaped blocks 314 to move in the reverse direction, driving the two grinding wheels 318 away through the gear roller 313. Then, the rotating motor 110 drives the clamped gear to rotate. After adjusting the position, the grinding disc 107 enters between the teeth again, and the electric push rod 316 pushes the grinding wheel 318 to contact the gear again for the grinding process at the next location. The electromagnet 222 is turned off, so that the magnetic attraction between the circular magnet 209 and the electromagnet 222 is lost. Then, the pull ring 227 is pulled to drive the limiting rod 223 to move in the limiting hole 224, and drive the pushing rod 206, the conical block 207, the fixing rod 208 and the circular magnet 209 to move, so that the circular magnet 209 moves out of the magnetic attraction groove 220 and returns to the movable hole 218 through the jack 221. As the conical block 207 moves, it drives the two adjusting rollers 211 to roll downward in the two inclined grooves 216 respectively. At this time, the outward thrust received by the adjusting rollers 211 gradually decreases, and the return spring 215 starts to rebound, so that the distance between the two adjusting rollers 211 gradually becomes shorter. Through the roller frame 210 and the circular plate 212, the ejector rod 213 is driven to move inside the reinforcing rod 202, further driving the triangular clamping block 214 to move from the triangular groove 219 to the inside of the triangular hole 217. At this time, the connection between the reinforcing rod 202 and the fixing plate 201 is lost, and the reinforcing rod 202 can be removed separately, which is convenient for removing the grinding assembly 2 for use on other shaping equipment. According to the cooperation of the triangular mark 225 and the indication mark 226, the reinforcing rod 202 can be moved to other positions. Then, the pull ring 227 is pushed to move in the reverse direction, and the conical block 207 and the fixing rod 208 are pushed to move through the pushing rod 206, and the circular magnet 209 is pushed from the jack 221 at the corresponding position into the magnetic attraction groove 220. The electromagnet 222 is started again, so that the circular magnet 209 is magnetically attracted to the electromagnet 222 to limit the conical block 207. When the conical block 207 moves, the adjusting rollers 211 roll upward from the lower part inside the inclined groove 216, and are simultaneously subjected to an outward thrust, so that the two ejector rods 213 move outward at the same time, and the triangular clamping block 214 is pushed from the triangular hole 217 into the triangular groove 219 again to fix the reinforcing rod 202, so as to achieve the effect of adjusting the position of the reinforcing rod 202, which is convenient for adjusting the position of the diamond-coated grinding plate 205 to adapt to gears of different sizes.

[0042] Among them, the horizontal feed system 103, the vertical feed system 104, the angle adjustment system 105, the grinding motor 106, the rotation motor 110, the electromagnet 222, the forward and reverse motor 302, the angle sensor 304, the dual-axis motor 307, the electric push rod 316 and the PLC controller 102 are all prior arts, and their components and working principles are all public technologies, so no further explanation will be given here.
