Description

Technical Field

[0001] The invention relates to the technical field of gear processing, in particular to a stable shaping device for processing reducer gears. Background Art

[0002] The reducer is also called a speed reducer. It adjusts the speed through the meshing transmission between gears of different specifications in the reducer. It is installed between the prime mover and the working machine. Its main function is to reduce the speed and increase the torque, thereby meeting the working machine's requirements for low speed and high torque. During the processing of the reducer gear, in order to improve the accuracy and surface quality of the gear, it is usually necessary to perform shaping processing to avoid burrs between the external teeth that affect the stability during meshing. Grinding shaping is a common tooth profile modification method. Tools such as grinding wheels or grinding belts are usually used. The surface of these tools has certain abrasive particles that can perform micro-grinding on the gear tooth surface.

[0003] In the prior art, during the grinding process of the reducer gear, the angle of the grinding wheel is generally adjusted through an adjustment system to match the angle of the gear teeth, and then the grooves between the teeth are ground by the grinding wheel. There is no grinding of the circumferential outer surface of the gear, and the function is relatively simple. When there are burrs or roughness on the outer surface of the gear, the bevel gear needs to be removed and then its outer surface needs to be ground and trimmed separately, which adds additional disassembly, installation and clamping work, consumes more time and manpower, reduces the smoothness of production, and affects work efficiency.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1.

Start the angle adjustment system, adjust the angle of the grinding disc, start the lateral feed system, and drive the grinding disc into the groove between the teeth. At the same time, the grinding assembly is driven to move together so that the diamond-coated grinding plate contacts the outer surface of the gear. Start the vertical feed system and the grinding motor, 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 outer surface of the gear. With the cooperation of the grinding assembly and the grinding assembly, two parts can be processed at the same time, and more grinding work can be completed in the same time, effectively shortening the overall processing time.

[0017] 2. When the present invention is used, start the forward and reverse motors to drive the rotating rod, rotating plate and 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 motors to turn off, and then start the two electric push rods to push the two T-shaped sleeves, T-shaped blocks and gear rollers to move relative to each other, so that the two grinding wheels contact the top and bottom of the gear. Start the dual-axis motor to drive the rotating shaft, driving gear, chain, driven gear and two I-shaped blocks to rotate, and drive the two grinding wheels to rotate together through the two gear rollers to grind the edges of the top and bottom of the gear. The grinding assembly, grinding assembly and upper and lower grinding assemblies can work together at the same time, or work separately and locally, which is more flexible and functional.

[0018] 3. When the present invention is used, turn off the electromagnet, the magnetism disappears, pull the pull ring, and drive the push rod, the conical block, the fixed rod and the circular magnet to move through the limit rod, so that the circular magnet returns to the movable hole. As the conical block moves, the two adjustment rollers roll downward in the two inclined grooves respectively, and the reset spring begins to rebound, so that the distance between the two adjustment rollers gradually shortens, and drives the top rod to move inside the reinforcement rod, and pulls the triangular block to the inside of the triangular hole, so that the reinforcement rod can be removed separately, which is convenient for removing the grinding assembly and using it on other shaping equipment. According to the coordination of the triangle mark and the indicator mark, the reinforcement rod can be moved to other positions, and then the pull ring is pushed to move in the opposite direction, so that the circular magnet and the electromagnet are magnetically attracted together, and the triangular block is pushed from the triangular hole into the inside of the triangular groove again to fix the reinforcement rod, thereby achieving the effect of adjusting the position of the diamond-coated grinding plate to adapt to gears of different sizes.

The outer surface of the reinforcement rod 202 is movably sleeved with a pull ring 227, and 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 hand-tightening bolts. One end of the two return springs 215 is fixedly connected to the inner wall of the reinforcement rod 202, and the other ends of the two return springs 215 are respectively fixedly connected to the outer surface of one side of the two circular plates 212.

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

[0023] In this embodiment, when in use, the lateral feeding system 103, the vertical feeding 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 plate 112 is as follows: Figure 3As shown, it has five vertical clamping columns. The gear to be ground is sleeved on the fixed shaft 111 and falls onto the clamping rod disk 112, so that the clamping column on the clamping rod disk 112 is inserted into the circular hole of the gear, and then the clamping screw 113 is screwed into the top of the fixed shaft 111, so as to fix the gear on the clamping rod disk 112 and clamp the gear. The lateral feed system 103 is used to control the lateral movement of the vertical feed system 104, and 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 groove between the gear teeth at a suitable angle to achieve uniform and precise grinding. After the gear is installed and fixed, the angle adjustment system 105 is started to adjust the angle of the grinding motor 106 and the grinding disc 107 so that the grinding disc 107 matches the angle of the inclined teeth on the outer surface of the gear, and then the horizontal feeding system 103 is started to drive the vertical feeding system 104, the angle adjustment system 105 and the grinding motor 106 to move toward the gear so that the grinding disc 107 enters the groove on the outer surface of the gear. When the angle adjustment system 105 moves, it drives the grinding assembly 2 to move together so that the inner wall of the diamond-coated grinding plate 205 contacts the circular outer surface of the gear. Start the vertical feed system 104 and the grinding motor 106. The grinding motor 106 drives the grinding disc 107 to rotate. 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 shape the teeth. At the same time, the diamond coated grinding plate 205 moves up and down on the outer surface of the gear to grind and shape the circular outer surface, making the outer surface of the gear smoother and more regular, which is conducive to accurately controlling the outer diameter size of the gear, cooperating with the grinding between the teeth, and improving the shape accuracy and position accuracy of the entire gear. With the cooperation of the grinding component 1 and the grinding component 2, two parts can be processed at the same time, and more grinding work can be completed in the same time, effectively shortening the overall processing time. There is no need to remove the gear and grind the outer surface separately, reducing the workload of disassembly and installation, and improving work efficiency. When one of the tooth grooves is polished, the lateral feed system 103 drives the vertical feed system 104 to move in the opposite direction, so that the grinding disc 107 moves away from between the teeth, and the diamond coated grinding plate 205 is separated from the outer surface of the gear. Then the rotating motor 110 controls the fixed shaft 111 to rotate, driving the clamping rod disc 112 and the clamped gear to rotate, so that the ground tooth moves away, and the next tooth to be ground rotates over. Under the control of the lateral feed system 103, the grinding disc 107 enters between the rotating teeth again to grind the area, and the diamond coated grinding plate 205 grinds the outer surface of the gear after rotation.The diamond-coated grinding plate 205 adopts a diamond coating. Diamond has extremely high hardness and wear resistance, so as to 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 during the grinding process of the reducer gear, the grooves between the teeth are generally ground, and the outer surface of the gear circumference is lacking. The function is relatively single. When the outer surface of the gear is relatively rough, the bevel gear needs to be removed and the outer surface needs to be ground and reshaped separately, which adds extra work, consumes more time and manpower, reduces the fluency of production, and affects work efficiency.

[0024] Embodiment 2: Figure 1-Figure 5 As shown, the upper and lower grinding components 3 include a fixed frame 301, a forward and reverse motor 302 is fixedly installed on the top surface inside the fixed frame 301, a rotating rod 303 is fixedly installed on the output end of the forward and reverse motor 302, an angle sensor 304 is arranged on the outer surface of the rotating rod 303, two rotating plates 305 are fixedly installed on the outer surface of the rotating rod 303, a U-shaped frame 306 is fixedly installed between the two rotating plates 305, a double-axis motor 307 is fixedly installed on the outer surface of one side of the U-shaped frame 306, rotating shafts 308 are fixedly installed on both output ends of the double-axis motor 307, driving gears 309 are fixedly installed on one end of the two rotating shafts 308, chains 310 are meshedly connected on the outer surfaces of the two driving gears 309, driven gears 311 are meshedly connected inside the two chains 310, and I-shaped blocks 312 are fixedly installed on the opposite sides of the two driven gears 311, and gear rollers are meshedly connected inside the two I-shaped blocks 312 313, a T-block 314 is fixedly installed on the outer surface of one side of the two gear rollers 313, two mounting frames 315 are fixedly installed on the outer surface of the U-shaped frame 306, electric push rods 316 are fixedly installed inside the two mounting frames 315, and one end of the two electric push rods 316 is fixedly installed with a T-shaped sleeve 317, and the outer surface of the other side of the two gear rollers 313 is fixed with a grinding wheel 318 through bolts, and the top and bottom of the U-shaped frame 306 are provided with a rotating hole 319, and the outer surfaces of the two I-shaped blocks 312 are movably embedded in the inside of the two rotating holes 319, respectively, the rear surface of the fixed frame 301 is fixedly installed on the front surface of the grinding machine 101, and the bottom end of the rotating rod 303 is movably embedded in the bottom surface of the fixed frame 301, the outer surfaces of the two T-blocks 314 are movably embedded in the inside of the two T-shaped sleeves 317, and the outer surfaces of the two gear rollers 313 are movably embedded in the inside of the two driven gears 311.

[0025] In this embodiment, when in use, the grinding assembly 1 drives the grinding disc 107 to contact the groove between the teeth, and after the diamond-coated grinding plate 205 contacts the outer surface of the gear, the forward and reverse motor 302 is started, and 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 with the rotating rod 303 as the center, so that the two grinding wheels 318 rotate to the top and bottom of the gear, as shown in FIG. Figure 1As shown. At the same time, 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 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 motors 302 to turn off, so that the two grinding wheels 318 are located at the edges of the top and bottom of the gear respectively. Then, the two electric push rods 316 are started at the same time to push the two T-shaped sleeves 317 to move relative to each other, and push the two T-shaped blocks 314 to move relative to each other, so that the two gear rollers 313 move relative to each other in the corresponding I-shaped blocks 312, and further the two grinding wheels 318 move relative to each other and contact the top and bottom of the gear. When the grinding disc 107 and the diamond-coated grinding plate 205 are started, the dual-axis motor 307 is started at the same time. The two output ends of the dual-axis 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 and connected with the I-shaped block 312. When the I-shaped block 312 rotates, the two gear rollers 313 are driven to rotate together. At the same time, the T-block 314 rotates inside the T-sleeve 317, further driving the two grinding wheels 318 to rotate together, and grinding is performed on the edges of the top and bottom of the gear. With the cooperation of the grinding assembly 1, the grinding assembly 2 and the upper and lower grinding assemblies 3, the gears can be ground at different positions at multiple points at the same time, and the gears can be ground more comprehensively, which greatly improves the work efficiency. By removing the grinding assembly 1, the grinding assembly 1 can be used alone to grind the teeth of the gear. By driving the grinding disc 107, the grinding assembly 2 can be used alone to grind the outer surface of the gear. By only starting the upper and lower grinding assemblies 3, the top and bottom of the gear can be ground separately. The grinding assembly 1, the grinding assembly 2 and the upper and lower grinding assemblies 3 can work together at the same time or work separately and partially, which is more flexible and functional. When the lateral feed system 103 drives the grinding disc 107 to move in the reverse direction and reset, the dual-axis motor 307 is turned off, and the two electric push rods 316 are started again, and the two T-shaped sleeves 317 and the T-shaped block 314 are pulled to move in the reverse direction, and the two grinding wheels 318 are driven to leave through the gear roller 313 and separate from the gear. Then the motor 110 is rotated to drive 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 to perform the next grinding process.

[0027] In this embodiment, when in use, the electromagnet 222 is turned off by the PLC controller 102, so that the power is cut off and the magnetism disappears. At this time, the magnetic attraction between the circular magnet 209 and the electromagnet 222 is lost, and then the pull ring 227 is pulled to drive the limit rod 223 to move in the limit hole 224, and drive the push rod 206, the conical block 207, the fixing rod 208 and the circular magnet 209 to move, so that the circular magnet 209 leaves the magnetic attraction groove 220 and passes through the insertion hole 221 back to the movable hole 218. Fig. 9 As shown, with the movement of the conical block 207, the two adjusting rollers 211 are driven to roll downward in the two inclined grooves 216 respectively. At this time, the outward thrust on the adjusting roller 211 gradually decreases, and the extrusion force on the squeezed return spring 215 gradually decreases, and begins to rebound, generating a relative thrust on the two circular plates 212. When the adjusting roller 211 rolls 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 shortens, and the push rod 213 is driven to move into the reinforcement rod 202 through the roller frame 210 and the circular plate 212, and further drives 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 reinforcement rod 202 and the fixed plate 201 is lost, and the reinforcement 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 indicator mark 226, the reinforcing rod 202 can be moved to other positions, and then the pull ring 227 is pushed to move in the opposite direction, and the conical block 207 and the fixing rod 208 are pushed to move by the push rod 206, and the circular magnet 209 is pushed into the magnetic suction groove 220 from the corresponding position of the socket 221, and the electromagnet 222 is started again, so that the circular magnet 209 and the electromagnet 222 are magnetically attracted together to limit the conical block 207. When the conical block 207 moves, the adjusting roller 211 rolls from the lower position to the higher position inside the inclined groove 216, and is pushed outward at the same time, so that the two top 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, and the reinforcing rod 202 is fixed, so as to achieve the effect of adjusting the position of the reinforcing rod 202, and facilitate the adjustment of the position of the diamond-coated grinding plate 205 to adapt to gears of different sizes.

[0028] The effect and working principle of the whole mechanism are as follows: the gear to be ground is sleeved on the fixed shaft 111 and falls on the clamping rod disk 112, so that the clamping column on the clamping rod disk 112 is inserted into the circular hole of the gear, and then the pressing screw 113 is screwed into the top of the fixed shaft 111, so that the gear is fixed on the clamping rod disk 112. The angle adjustment system 105 is started, and the angles of the grinding motor 106 and the grinding disc 107 are adjusted so that the grinding disc 107 matches the angle of the inclined teeth on the outer surface of the gear, and then the horizontal feeding system 103 is started to drive the vertical feeding system 104, the angle adjustment system 105 and the grinding motor 106 to move toward the gear, so that the grinding disc 107 enters the groove on the outer surface of the gear. When the angle adjustment system 105 moves, it drives the grinding assembly 2 to move together, so that the inner wall of the diamond-coated grinding plate 205 contacts the circular outer surface of the gear. Start the forward and reverse motor 302 to drive the rotating rod 303 to rotate, and drive the U-shaped frame 306 to rotate with the rotating rod 303 as the center through the two rotating plates 305, so that the two grinding wheels 318 rotate to the top and bottom of the gear. At the same time, 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 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. Then start the two electric push rods 316 at the same time, push the two T-shaped sleeves 317 to move relative to each other, and push the two T-shaped blocks 314 to move relative to each other, so that the two gear rollers 313 move relative to each other in the corresponding I-shaped blocks 312, and further make the two grinding wheels 318 move relative to each other and contact the top and bottom of the gear. Start the vertical feed system 104 and the grinding motor 106. The grinding motor 106 drives the grinding disc 107 to rotate. 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 shape the teeth. At the same time, the diamond-coated grinding plate 205 moves up and down on the outer surface of the gear to grind and shape the circular outer surface. With the cooperation of the grinding assembly 1 and the grinding assembly 2, two parts can be processed at the same time. Start the dual-axis motor 307 to 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, the two I-shaped blocks 312 and the two gear rollers 313 are driven to rotate together, and the two grinding wheels 318 are further driven to rotate together to grind the edges of the top and bottom of the gear.When one of the tooth grooves is polished, the lateral 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, the diamond-coated grinding plate 205 is separated from the outer surface of the gear, 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 the T-shaped blocks 314 to move in the reverse direction, and the two grinding wheels 318 are driven to move away through the gear roller 313, and then the motor 110 is rotated to drive 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 to carry out the next grinding process. Turn off the electromagnet 222 to lose the magnetic attraction between the circular magnet 209 and the electromagnet 222, then pull the pull ring 227 to drive the limit rod 223 to move in the limit hole 224, and drive the push rod 206, the conical block 207, the fixing rod 208 and the circular magnet 209 to move, so that the circular magnet 209 leaves the magnetic attraction groove 220 and passes through the insertion hole 221 back to the movable hole 218. As the conical block 207 moves, the two adjusting rollers 211 are driven to roll downward in the two inclined grooves 216 respectively. At this time, the outward thrust on the adjusting rollers 211 gradually decreases, and the return spring 215 begins to rebound, so that the distance between the two adjusting rollers 211 gradually shortens, and the top rod 213 is driven to move into the reinforcement rod 202 through the roller frame 210 and the circular plate 212, and further drives 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 reinforcement rod 202 and the fixed plate 201 is lost, and the reinforcement 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 indicator mark 226, the reinforcing rod 202 can be moved to other positions, and then the pull ring 227 is pushed to move in the opposite direction, and the conical block 207 and the fixing rod 208 are pushed to move by the push rod 206, and the circular magnet 209 is pushed into the magnetic suction groove 220 from the corresponding position of the socket 221, and the electromagnet 222 is started again, so that the circular magnet 209 and the electromagnet 222 are magnetically attracted together to limit the conical block 207. When the conical block 207 moves, the adjusting roller 211 rolls from the lower position to the higher position inside the inclined groove 216, and is pushed outward at the same time, so that the two top 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, and the reinforcing rod 202 is fixed, so as to achieve the effect of adjusting the position of the reinforcing rod 202, and facilitate the adjustment of the position of the diamond-coated grinding plate 205 to adapt to gears of different sizes.
