Description

Technical Field

[0001] The invention relates to the technical field of crankshaft rolling, and in particular to a crankshaft rolling device for an air-conditioning compressor. Background Art

[0002] The crankshaft of the air-conditioning compressor is one of its core components, responsible for converting mechanical energy into compression kinetic energy of the compressor. Gray cast iron is one of the commonly used crankshaft materials in traditional compressors. It has good wear resistance and strength, and is suitable for some low-end applications and industrial uses. Some advanced compressors use aluminum alloy to manufacture crankshafts because of their lightweight, corrosion resistance and good thermal conductivity. Aluminum alloy crankshafts are generally used in high-performance, high-efficiency and lightweight applications. The outer end of the air-conditioning compressor crankshaft needs to be rolled during processing. The rolling of the air-conditioning compressor crankshaft in the prior art is mainly carried out by a rolling machine, which uses manual labor to continuously put the crankshaft into the rolling machine for rolling, which is dangerous. At the same time, it is impossible to carry out continuous compressor crankshaft rolling processing, and the degree of automation is low. Summary of the invention

[0003] In view of the above technical problems, the technical solution adopted by the present invention is: an air-conditioning compressor crankshaft rolling device, including a shaft feed device, the shaft feed device includes a feed box, the shaft feed device is used to feed the air-conditioning compressor main shaft, the shaft feed device is provided with a rolling device and a shaft outlet device, the rolling device includes a sliding motor frame and a rolling frame, the sliding motor frame is slidably installed on the feed box, the rolling device is used to roll the air-conditioning compressor main shaft, the shaft outlet device includes a rear docking gear, the rear docking gear is rotatably installed on the feed box, and the shaft outlet device is used to send out the rolled air-conditioning compressor main shaft.

[0004] Furthermore, the shaft feeding device includes a pushing electric cylinder fixedly mounted on the feed box, a pushing plate fixedly mounted on the top of the pushing electric cylinder, a plurality of crankshafts are placed in the feed box, and a long groove is provided in the feed box so that the bent part of the crankshaft is located in the long groove.

[0005] Furthermore, the feed box is provided with a sensing mechanism, which includes a retraction switch fixedly mounted on the feed box, a top block is slidably mounted on the feed box, a rear push plate is fixedly mounted on the top block, a push plate spring is provided between the rear push plate and the feed box, and a start switch is fixedly mounted on the feed box.

[0006] Put the crankshafts into the feed box one by one. When the start switch is pressed, the push cylinder extends and drives the push plate to push the crankshaft, pushing all the crankshafts backwards. The front crankshaft contacts the rear push plate, pushing the top block to move toward the retraction switch, and the push plate spring is compressed. When the retraction switch is pressed, the push cylinder stops extending and starts to retract, and the motor starts to rotate. At this time, the crankshaft falls from the feed box to the push rack, and then the push plate spring rebounds and drives the top block to leave the retraction switch while the rear push plate returns to the initial position to prevent subsequent crankshafts from falling in, ensuring that only one crankshaft is pushed out each time.

[0007] Furthermore, the rolling device includes a motor fixedly mounted on a sliding motor frame, a motor gear is fixedly mounted on the motor shaft of the motor, a split-tooth gear, a docking gear and an eccentric gear are rotatably mounted on the feed box, half of the upper half of the split-tooth gear is densely toothed, and the other half is sparsely toothed, and the lower half of the split-tooth gear is all densely toothed, the upper half of the split-tooth gear is meshed with the eccentric gear, the docking gear is meshed with the eccentric gear, a short push rod is rotatably mounted on the eccentric gear, the lower half of the split-tooth gear is meshed with the motor gear, a long push rod is rotatably mounted on the short push rod, a side rail is fixedly mounted on the feed box, a sliding frame is slidably mounted on the side rail, the sliding frame is rotatably mounted with the long push rod, a rotating rod is rotatably mounted on the sliding frame, a self-weight pressure roller is rotatably mounted on the rotating rod, a rotating gear is fixedly mounted on the self-weight pressure roller, a rolling rack is fixedly mounted on the rolling frame, and the rolling rack is meshed with the rotating gear.

[0008] Furthermore, a propulsion mechanism is provided on the feed box, and the propulsion mechanism includes a propulsion gear rotatably installed on the feed box, the propulsion gear is meshed with the upper half of the toothed gear, a propulsion frame is slidably installed on the feed box, a slow-release spring is provided between the propulsion frame and the feed box, and a propulsion rack is fixedly installed on the propulsion frame, and the propulsion rack is meshed with the propulsion gear.

[0009] Furthermore, a pushing and turning mechanism is arranged in the pushing frame, and the pushing and turning mechanism includes a lifting frame slidably mounted on the pushing frame, a turning and pushing frame is rotatably mounted on the lifting frame, and the turning and pushing frame is not located directly below the crankshaft. The crankshaft pushed down from the feed box falls onto the pushing frame and the turning and pushing frame. Two springs on both sides are arranged between the turning and pushing frame and the lifting frame. A guide column is fixedly mounted on the lifting frame, and a track plate is fixedly mounted in the feed box. The guide column and the track plate are slidably mounted.

[0010] After being pushed out, the crankshaft falls into the gap of the push frame. The crankshaft part is located on the rotating push frame. The rotation of the motor drives the motor gear to rotate, thereby driving the split gear to rotate. The rotation of the split gear drives the docking gear to rotate quickly, thereby driving the eccentric gear to rotate, thereby driving the short push rod and the long push rod to rotate, thereby driving the sliding frame to slide back and forth along the side rail, thereby driving the self-weight pressure roller to move back and forth along the rolling frame through the rotating rod, and the rolling rack drives the rotating gear and the self-weight pressure roller to rotate.

[0011] The rotation of the split gear will also drive the propulsion gear to rotate. The dense tooth part of the split gear at this time is meshed with the propulsion gear, thereby driving the propulsion rack and the propulsion frame to slide along the feed box, thereby carrying the crankshaft toward the rolling frame through the propulsion frame, and the slow-release spring is stretched. When the guide column contacts the protrusion of the track plate, the end of the crankshaft reaches the rolling frame, and the self-weight pressure roller begins to roll the end of the crankshaft. The self-weight pressure roller is heavy, and the material of the crankshaft is aluminum or gray cast iron. The crankshaft will not lift the self-weight pressure roller and the rotating rod, and the lifting frame begins to rise along the propulsion frame, driving the rotating push frame to rotate and rise, and the rotating push frame drives the crankshaft to rotate along the propulsion frame, and cooperates with the self-weight pressure roller to roll the end of the crankshaft. When the crankshaft contacts the self-weight pressure roller, the sparse tooth part of the upper part of the split gear begins to mesh with the propulsion gear, and the speed of the propulsion gear is halved, so that the crankshaft is slowly rolled.

[0012] Furthermore, the shaft output device includes a lower gear rotatably mounted on the feed box, an upper bevel gear is fixedly mounted on the lower gear, the lower gear is meshed with the rear docking gear, a rear gear, a side gear and a transmission wheel are rotatably mounted on the feed box, a side bevel gear is fixedly mounted on the rear gear, the side bevel gear is meshed with the upper bevel gear, the rear gear is meshed with the side gear, the side gear is meshed with the transmission wheel, an output shaft is rotatably mounted on the feed box, a belt gear and an output frame are fixedly mounted on the output shaft, and a transmission belt is wrapped around the belt gear and the transmission wheel.

[0013] Furthermore, a lifting mechanism is provided on the transmission wheel, and the lifting mechanism includes a cam fixedly mounted on the transmission wheel, a lifting frame is slidably mounted on the sliding frame, a lifting column is fixedly mounted on the lifting frame, and the lifting frame cooperates with the cam.

[0014] When the crankshaft is about to be rolled, the farthest end of the crankshaft contacts the sliding motor frame, and the crankshaft moves forward to push the sliding motor frame to slide along the feed box, thereby driving the motor gear to disengage from the toothed gear, and at this time the sliding motor frame is disengaged from the starting switch, and the toothed gear begins to mesh with the rear docking gear, and the motor rotation drives the motor gear to rotate, and the motor gear rotation drives the rear docking gear to rotate, thereby driving the lower gear to rotate, thereby driving the side bevel gear and the rear gear to rotate through the upper bevel gear, thereby driving the side gear and the transmission wheel to rotate, thereby driving the belt gear and the output shaft to rotate through the transmission belt, thereby driving the output frame to rotate, and the rotation of the transmission wheel will simultaneously drive the cam to rotate, thereby driving the lifting frame and the lifting column to rise, and the lifting column drives the rotating rod to rotate relative to the sliding frame, so that the self-weight pressure roller leaves the top of the crankshaft, and the crankshaft that has been rolled on the push frame is taken away by the output frame. When taking it away, the output frame takes the crankshaft away from the gap between the push frame and the push frame and the gap between the rolling frame and the sliding motor frame.

[0015] When the motor gear is disengaged from the toothed gear, the slow-release spring begins to rebound slowly, driving the propulsion frame to move in the direction of the start switch. When the propulsion frame contacts the sliding motor frame, it pushes the sliding motor frame to slide along the feed box, causing the sliding motor frame to contact the start switch. At this time, the push cylinder begins to extend and the motor stops rotating. At this time, the motor gear is disengaged from the rear docking gear, and the motor gear begins to re-engage with the toothed gear, preparing to start the rolling operation of the next crankshaft.

[0016] Compared with the prior art, the present invention has the following beneficial effects: (1) the shaft feeding device provided in the present invention is used to continuously feed the crankshafts of the air-conditioning compressor into the rolling device one by one for rolling processing, and automatically and continuously feed out the rolled crankshafts of the air-conditioning compressor through the shaft discharging device, which has a high degree of automation; (2) when the rolling device provided in the present invention rolls the crankshaft of the air-conditioning compressor, the moving speed of the crankshaft is reduced, and the crankshaft is driven to rotate continuously, and the crankshaft of the air-conditioning compressor is rolled with the heavy deadweight pressure roller, so that the rolling effect is good; (3) the rolling device and the shaft discharging device provided in the present invention are driven by a motor, so that all actions are coordinated, reducing the difficulty of the control system, and when the output rack sends out the crankshaft of the air-conditioning compressor, the lifting device lifts the deadweight pressure roller, so that the crankshaft of the air-conditioning compressor can be taken out smoothly, which has a high degree of automation.

[0033] The crankshafts 104 are placed in the feed box 101 one by one. When the start switch 219 is pressed, the push cylinder 102 extends and drives the push plate 105 to push the crankshafts 104, pushing all the crankshafts 104 backwards. The front crankshaft 104 contacts the rear push plate 106, pushing the top block 108 to move toward the retraction switch 103, and the push plate spring 107 is compressed. When the retraction switch 103 is pressed, the push cylinder 102 stops extending and starts to retract, and the motor 202 starts to rotate. At this time, the crankshaft 104 falls from the feed box 101 onto the rotating push frame 222, and then the push plate spring 107 rebounds and drives the top block 108 to leave the retraction switch 103 while the rear push plate 106 returns to the initial position to prevent subsequent crankshafts 104 from falling in, ensuring that only one crankshaft 104 is pushed out each time.

[0035] like Figure 4-Figure 9 As shown, a propulsion mechanism is provided on the feed box 101, and the propulsion mechanism includes a propulsion gear 216 rotatably mounted on the feed box 101, the propulsion gear 216 is meshed with the upper half of the toothed gear 211, a propulsion frame 218 is slidably mounted on the feed box 101, a slow-release spring 220 is provided between the propulsion frame 218 and the feed box 101, and a propulsion rack 217 is fixedly mounted on the propulsion frame 218, and the propulsion rack 217 is meshed with the propulsion gear 216.

[0036] like Figure 4-Figure 9 As shown, a pushing and turning mechanism is arranged in the pushing frame 218, and the pushing and turning mechanism includes a lifting frame 221 slidably mounted on the pushing frame 218, and a turning and pushing frame 222 is rotatably mounted on the lifting frame 221. The turning and pushing frame 222 is not located directly below the crankshaft 104. The crankshaft 104 pushed down from the feed box 101 falls onto the pushing frame 218 and the turning and pushing frame 222. Two springs 223 on both sides are arranged between the turning and pushing frame 222 and the lifting frame 221. A guide column 225 is fixedly mounted on the lifting frame 221, and a track plate 224 is fixedly mounted in the feed box 101. The guide column 225 and the track plate 224 are slidably mounted.

[0037] After being pushed out, the crankshaft 104 falls into the gap of the pushing frame 218, and the crankshaft part is located on the rotating pushing frame 222. The rotation of the motor 202 drives the motor gear 210 to rotate, thereby driving the toothed gear 211 to rotate. The rotation of the toothed gear 211 drives the docking gear 212 to rotate quickly, thereby driving the eccentric gear 213 to rotate, thereby driving the short push rod 214 and the long push rod 215 to rotate, thereby driving the sliding frame 204 to slide back and forth along the side rail 203, thereby driving the self-weight pressure roller 206 to move back and forth along the rolling frame 208 through the rotating rod 205, and the rolling rack 209 drives the rotating gear 207 and the self-weight pressure roller 206 to rotate.

[0038] The rotation of the toothed gear 211 will also drive the propulsion gear 216 to rotate. The dense tooth part of the toothed gear 211 is meshed with the propulsion gear 216, thereby driving the propulsion rack 217 and the propulsion frame 218 to slide along the feed box 101, thereby advancing the crankshaft 104 toward the rolling frame 208 through the propulsion frame 218, and the slow-release spring 220 is stretched. When the guide column 225 contacts the protrusion of the track plate 224, the end of the crankshaft 104 arrives on the rolling frame 208, and the self-weight roller 206 starts to roll the end of the crankshaft 104. The self-weight roller 206 is heavy, and the crankshaft 104 is The material of 104 is aluminum or gray cast iron, and the crankshaft 104 will not lift the self-weight pressure roller 206 and the rotating rod 205. The lifting frame 221 begins to rise along the propulsion frame 218, and drives the rotating push frame 222 to rotate and rise. The rotating push frame 222 drives the crankshaft 104 to rotate along the propulsion frame 218, and cooperates with the self-weight pressure roller 206 to roll the end of the crankshaft 104. When the crankshaft 104 contacts the self-weight pressure roller 206, the sparse tooth part of the upper part of the toothed gear 211 begins to mesh with the propulsion gear 216, and the rotation speed of the propulsion gear 216 is halved, so that the crankshaft 104 is slowly rolled.

[0039] like Fig.10 , Fig.11 As shown, the shaft output device includes a lower gear 302 rotatably mounted on the feed box 101, an upper bevel gear 303 is fixedly mounted on the lower gear 302, the lower gear 302 is meshed with the rear docking gear 301, a rear gear 305, a side gear 306 and a transmission wheel 307 are rotatably mounted on the feed box 101, a side bevel gear 304 is fixedly mounted on the rear gear 305, the side bevel gear 304 is meshed with the upper bevel gear 303, the rear gear 305 is meshed with the side gear 306, the side gear 306 is meshed with the transmission wheel 307, an output shaft 311 is rotatably mounted on the feed box 101, a belt gear 309 and an output frame 312 are fixedly mounted on the output shaft 311, and a transmission belt 310 is wrapped around the belt gear 309 and the transmission wheel 307.

[0040] like Fig.10 , Fig.11 As shown, a lifting mechanism is provided on the transmission wheel 307, and the lifting mechanism includes a cam 308 fixedly mounted on the transmission wheel 307, a lifting frame 313 is slidably mounted on the sliding frame 204, a lifting column 314 is fixedly mounted on the lifting frame 313, and the lifting frame 313 cooperates with the cam 308.

[0041] When the crankshaft 104 is about to be rolled, the farthest end of the crankshaft 104 contacts the sliding motor frame 201, and the crankshaft 104 moves forward to push the sliding motor frame 201 to slide along the feed box 101, thereby driving the motor gear 210 to disengage from the toothed gear 211, and at this time the sliding motor frame 201 is disengaged from the start switch 219, and the toothed gear 211 begins to mesh with the rear docking gear 301, the motor 202 rotates to drive the motor gear 210 to rotate, and the motor gear 210 rotates to drive the rear docking gear 301 to rotate, thereby driving the lower gear 302 to rotate, thereby driving the side bevel gear 304 and the rear gear 305 to rotate through the upper bevel gear 303, thereby driving the side gear 306 and the transmission gear 306. The driving wheel 307 rotates, thereby driving the gear 309 and the output shaft 311 to rotate through the transmission belt 310, thereby driving the output frame 312 to rotate. The rotation of the driving wheel 307 will also drive the cam 308 to rotate, thereby driving the lifting frame 313 and the lifting column 314 to rise. The lifting column 314 drives the rotating rod 205 to rotate relative to the sliding frame 204, so that the self-weight pressure roller 206 leaves the top of the crankshaft 104. At this time, the crankshaft 104 rolled on the pushing frame 218 is removed by the output frame 312. When removing it, the output frame 312 removes the crankshaft 104 from the gap between the rotating and pushing frame 222 and the pushing frame 218 and the gap between the rolling frame 208 and the sliding motor frame 201.

[0042] When the motor gear 210 is disengaged from the toothed gear 211, the slow-release spring 220 begins to rebound slowly, driving the propulsion frame 218 to move toward the direction of the start switch 219. When the propulsion frame 218 contacts the sliding motor frame 201, it pushes the sliding motor frame 201 to slide along the feed box 101, so that the sliding motor frame 201 contacts the start switch 219. At this time, the pushing cylinder 102 begins to extend and the motor 202 stops rotating. At this time, the motor gear 210 is disengaged from the rear docking gear 301, and the motor gear 210 begins to re-engage with the toothed gear 211, preparing to start the rolling operation of the next crankshaft 104.

[0043] The working principle of an air-conditioning compressor crankshaft rolling device disclosed in the present invention is as follows: the crankshafts 104 are placed in the feed box 101 in sequence. When the start switch 219 is pressed, the push cylinder 102 extends and drives the push plate 105 to push the crankshafts 104, pushing all the crankshafts 104 backwards. The front crankshaft 104 contacts the rear push plate 106, pushing the top block 108 to move toward the retraction switch 103, and the push plate spring 107 is compressed. When the retraction switch 103 is pressed, the push cylinder 102 stops extending and starts to retract, and the motor 202 starts to rotate. At this time, the crankshaft 104 falls from the feed box 101 onto the rotating push frame 222, and then the push plate spring 107 rebounds and drives the top block 108 to leave the retraction switch 103 while the rear push plate 106 returns to the initial position to prevent subsequent crankshafts 104 from falling in, ensuring that only one crankshaft 104 is pushed out each time. After being pushed out, the crankshaft 104 falls into the gap of the pushing frame 218, and the crankshaft part is located on the rotating pushing frame 222. The rotation of the motor 202 drives the motor gear 210 to rotate, thereby driving the toothed gear 211 to rotate. The rotation of the toothed gear 211 drives the docking gear 212 to rotate quickly, thereby driving the eccentric gear 213 to rotate, thereby driving the short push rod 214 and the long push rod 215 to rotate, thereby driving the sliding frame 204 to slide back and forth along the side rail 203, thereby driving the self-weight pressure roller 206 to move back and forth along the rolling frame 208 through the rotating rod 205, and the rolling rack 209 drives the rotating gear 207 and the self-weight pressure roller 206 to rotate. The rotation of the toothed gear 211 will also drive the propulsion gear 216 to rotate. The dense tooth part of the toothed gear 211 is meshed with the propulsion gear 216, thereby driving the propulsion rack 217 and the propulsion frame 218 to slide along the feed box 101, thereby advancing the crankshaft 104 toward the rolling frame 208 through the propulsion frame 218, and the slow-release spring 220 is stretched. When the guide column 225 contacts the protrusion of the track plate 224, the end of the crankshaft 104 arrives on the rolling frame 208, and the self-weight roller 206 starts to roll the end of the crankshaft 104. The self-weight roller 206 is heavy, and the crankshaft 104 is The material of 104 is aluminum or gray cast iron, and the crankshaft 104 will not lift the self-weight pressure roller 206 and the rotating rod 205. The lifting frame 221 begins to rise along the propulsion frame 218, and drives the rotating push frame 222 to rotate and rise. The rotating push frame 222 drives the crankshaft 104 to rotate along the propulsion frame 218, and cooperates with the self-weight pressure roller 206 to roll the end of the crankshaft 104. When the crankshaft 104 contacts the self-weight pressure roller 206, the sparse tooth part of the upper part of the toothed gear 211 begins to mesh with the propulsion gear 216, and the rotation speed of the propulsion gear 216 is halved, so that the crankshaft 104 is slowly rolled.When the crankshaft 104 is about to be rolled, the farthest end of the crankshaft 104 contacts the sliding motor frame 201, and the crankshaft 104 moves forward to push the sliding motor frame 201 to slide along the feed box 101, thereby driving the motor gear 210 to disengage from the toothed gear 211, and at this time the sliding motor frame 201 is disengaged from the start switch 219, and the toothed gear 211 begins to mesh with the rear docking gear 301, the motor 202 rotates to drive the motor gear 210 to rotate, and the motor gear 210 rotates to drive the rear docking gear 301 to rotate, thereby driving the lower gear 302 to rotate, thereby driving the side bevel gear 304 and the rear gear 305 to rotate through the upper bevel gear 303, thereby driving the side gear 306 and the transmission gear 306. The driving wheel 307 rotates, thereby driving the gear 309 and the output shaft 311 to rotate through the transmission belt 310, thereby driving the output frame 312 to rotate. The rotation of the driving wheel 307 will also drive the cam 308 to rotate, thereby driving the lifting frame 313 and the lifting column 314 to rise. The lifting column 314 drives the rotating rod 205 to rotate relative to the sliding frame 204, so that the self-weight pressure roller 206 leaves the top of the crankshaft 104. At this time, the crankshaft 104 rolled on the pushing frame 218 is removed by the output frame 312. When removing it, the output frame 312 removes the crankshaft 104 from the gap between the rotating and pushing frame 222 and the pushing frame 218 and the gap between the rolling frame 208 and the sliding motor frame 201. When the motor gear 210 is disengaged from the toothed gear 211, the slow-release spring 220 begins to rebound slowly, driving the propulsion frame 218 to move in the direction of the start switch 219. When the propulsion frame 218 contacts the sliding motor frame 201, it pushes the sliding motor frame 201 to slide along the feed box 101, so that the sliding motor frame 201 contacts the start switch 219. At this time, the pushing cylinder 102 begins to extend, and the motor 202 stops rotating. At this time, the motor gear 210 is disengaged from the rear docking gear 301, and the motor gear 210 begins to re-engage with the toothed gear 211, preparing to start the rolling operation of the next crankshaft 104.
