Description

Technical Field

[0001] The invention relates to the technical field of loading and unloading for motor shaft machining, and in particular to an automatic loading and unloading device for motor shaft machining. Background Art

[0002] In traditional processing, motor shafts are usually manually loaded and unloaded and processed. With the development of technology, fully automatic machine tools have entered factories, which has led to the need for continuous manual loading and unloading to achieve automatic processing of motor shafts. At this time, if you want to increase production capacity, you need to perform automatic loading and unloading; with the development of manipulators, automatic loading and unloading has entered factories. Multi-axis picking of manipulators is suitable for a variety of working conditions and can also be used for motor shaft processing. However, each work process of the manipulator is unloading, picking, loading and waiting. The waiting time is too long, and a loading and unloading device dedicated to motor shaft processing is needed to improve the processing efficiency of the motor shaft. The automatic loading and unloading device for motor shafts in the prior art still requires manual placement of the workpiece on the support table, which does not actually solve the problem, resulting in the inability to continuously process the motor shaft and a poor degree of automation.

[0004] Furthermore, the main device includes a swivel seat fixedly mounted on a main frame, two fixed gear seats fixedly mounted on the main frame, an extension plate fixedly mounted on the main frame, a feeding mechanism arranged on the main frame, and a discharging mechanism arranged on the extension plate.

[0005] Furthermore, the feeding mechanism includes an axle feed box fixedly mounted on the main frame, a feed spring is slidably mounted in the axle feed box, a feed plate is arranged between the feed spring and the axle feed box, an axle feed trolley is slidably mounted on the main frame, an axle feed hole is arranged on the axle feed trolley, a left motor is fixedly mounted on the axle feed trolley, a motor gear is fixedly mounted on the motor shaft of the left motor, a left vertical shaft is rotatably mounted on the axle feed trolley, a left lower gear and a left upper gear are fixedly mounted on the left vertical shaft, and a left rack is fixedly mounted on the axle feed trolley.

[0006] Furthermore, the discharging mechanism includes an axle discharging trolley slidably mounted on the extending plate, a motor frame is fixedly mounted on the axle discharging trolley, a right motor is fixedly mounted on the motor frame, a right motor gear is fixedly mounted on the motor shaft of the right motor, a fixed column is fixedly mounted on the axle discharging trolley, a lifting column is slidably mounted on the fixed column, a right turning column is rotatably mounted on the lifting column, a right upper gear and a right lower gear are fixedly mounted on the right turning column, a lifting connecting rod is rotatably mounted on the lifting column, a right slider is rotatably mounted on the lifting connecting rod, a slide rail is fixedly mounted on the axle discharging trolley, the right slider is slidably mounted on the slide rail, a right connecting rod is fixedly mounted on the right slider, the right connecting rod is fixedly mounted on the main frame, and a right rack is fixedly mounted on the axle discharging trolley.

[0007] Furthermore, a right roller is rotatably mounted on the axle-out vehicle, and a left roller is rotatably mounted in the axle-in vehicle.

[0008] Multiple motor shafts to be processed are placed in the shaft input box. The motor shafts are tensioned between the feed spring and the inner wall of the shaft input box through the feed plate. The weight of the motor shaft is greater than the elastic force of the feed plate. Driven by the left rack, the shaft input car slides in the shaft input box. When the shaft placement hole reaches under the motor shaft, the motor shaft falls into the shaft placement hole because the gravity of the motor shaft is greater than the elastic force of the feed plate. As the shaft input car moves forward, the motor shaft is transported forward.

[0009] Furthermore, the rotating arm device includes two unlocking frames fixedly mounted on the main frame, and two mechanical arm mechanisms are arranged on the main frame. The mechanical arm mechanism includes a rotating arm rotatably mounted on the main frame, and an upper gear and a lower gear are fixed on the rotating arm. A transmission belt is wrapped around the two upper gears, and the lower gear of the mechanical arm mechanism close to the feeding mechanism side is meshed with the left rack, and the lower gear of the mechanical arm mechanism close to the discharging mechanism side is meshed with the right rack.

[0010] Furthermore, the mechanical arm mechanism also includes a sliding seat fixedly installed on the rotating arm, a tooth block is slidably installed on the sliding seat, a tooth spring is arranged between the tooth block and the sliding seat, a rotating gear plate is rotatably installed on the rotating arm, the tooth block cooperates with the rotating gear plate, two clamping claws are rotatably installed on the rotating gear plate, a docking gear is rotatably installed on the rotating gear, a clamping link is rotatably installed on the docking gear, the clamping link and the clamping claw are rotatably installed, a rotating claw is rotatably installed on the clamping claw, and a spring is arranged between the rotating claw and the clamping claw.

[0011] The transmission belt drives the rotating arm and the lower gear near the left rack side to rotate ninety degrees clockwise, thereby driving the left rack to move through the lower gear, and the left rack drives the axle-feeding car to slide inward. Under the action of the unlocking frame, the tooth block is lifted and the tooth spring is compressed. At this time, the tooth block is disengaged from the rotating gear plate, and the rotating gear plate is meshed with the fixed gear seat. Under the action of the fixed gear seat, the rotating gear plate rotates ninety degrees. At this time, the unlocking frame no longer lifts the tooth block, and the tooth block drops under the action of the tooth spring to clamp the rotating gear plate. At this time, the clamping claw is in a horizontal state and is located on both sides of the motor shaft in the shaft hole. At this time, the docking gear is meshed with the upper left gear, and the left motor drives the motor gear to rotate, thereby driving the lower left gear and the left vertical shaft to rotate, thereby driving the upper left gear to rotate, thereby driving the docking gear to rotate, thereby driving the clamping connecting rod to rotate, driving the clamping claw to tighten, and clamping the motor shaft through the rotating claw, and the spring is used to keep the rotating claw and the motor shaft in contact.

[0012] Then the transmission belt will reverse and drive the upper gear and the rotating arm to rotate counterclockwise 180 degrees. Similarly, under the action of the fixed gear seat and the unlocking frame, the rotating gear plate rotates 90 degrees, so that the motor shaft is in a horizontal state at this time. At this time, the rotating arm has rotated 90 degrees counterclockwise compared to the initial state. At this time, the docking gear is engaged with the opening and closing gear. The rotation of the opening and closing gear causes the docking gear to rotate, thereby driving the clamping connecting rod to rotate, so that the clamping claw and the rotating claw release the motor shaft. At this time, the motor shaft is located at the spindle of the processing machine for processing. At this time, the left rack drives the feed shaft car to retreat for the next feeding.

[0013] Since the two rotating arms must be in the same direction, when the transmission belt rotates, it will also drive the rotating arm close to the shaft outlet vehicle side to rotate at the same time. After the motor shaft is processed, the clamping claw on the rotating arm close to the shaft outlet vehicle side is in a vertical state, and the processed motor shaft is in a horizontal state. The rotation of the opening and closing gear drives the docking gear to rotate, thereby driving the clamping connecting rod to rotate, thereby driving the clamping claw and the rotating claw to clamp the processed motor shaft. Subsequently, the transmission belt rotates and drives the rotating arm close to the shaft outlet vehicle side to rotate 180 degrees counterclockwise. Under the action of the fixed gear seat, the clamping claw becomes horizontal, and the motor shaft is in a vertical state.

[0014] At the same time, the rotation of the rotating arm and the lower gear will drive the right rack and the axle-out vehicle to slide inward along the extended plate, driving the right slider to slide in the slide rail, thereby driving the lifting connecting rod to rotate, thereby driving the lifting column to rise along the fixed column, driving the lower right gear to engage with the right motor gear, and at this time the upper right gear is engaged with the docking gear close to the axle-out vehicle side, the motor shaft is located above the cylindrical hole of the axle-out vehicle, and the rotation of the right motor drives the right motor gear to rotate, thereby driving the lower right gear and the right rotating column to rotate, thereby driving the upper right gear to rotate, thereby driving the docking gear to rotate, driving the clamping connecting rod to rotate, driving the clamping claw to open, and dropping the motor shaft into the cylindrical hole of the axle-out vehicle. With the reverse movement of the transmission belt, the axle-out vehicle will be driven away from the main frame, the lifting column will descend, and the lower right gear will disengage from the right motor gear.

[0015] Furthermore, the picking and placing device includes a rotating motor fixedly mounted on the transfer rack, a lower motor gear is fixedly mounted on the motor shaft of the rotating motor, a turntable and two rotating shafts are rotatably mounted on the transfer rack, a tensioning gear and an internal gear are fixedly mounted on the rotating shaft, a turntable gear and an eccentric column are fixedly mounted on the turntable, the turntable gear is meshed with the lower motor gear, a belt is wrapped around the lower motor gear and the two internal gears, and a belt rotating mechanism is arranged on the rotating seat.

[0016] Furthermore, the belt transfer mechanism includes a rotating plate rotatably mounted on a rotating seat, two sliders slidably mounted on the rotating plate, small racks rotatably mounted on the sliders, a slider spring is arranged between the sliders and the rotating plate, the small rack cooperates with the transmission belt, a vertical frame is slidably mounted on the rotating plate, and the eccentric column slides in the vertical frame.

[0017] The rotating motor drives the lower motor gear to rotate, thereby driving the turntable gear to rotate, thereby driving the turntable to rotate, thereby driving the vertical frame to slide left and right through the eccentric column. At the same time, the vertical frame can slide inward and outward relative to the eccentric column, thereby driving the rotating plate to rotate relative to the rotating seat. The slider spring makes the small rack always clamped with the transmission belt, the small rack can rotate relative to the slider, and the rotating plate rotates, which will drive the transmission belt to continuously switch forward and reverse through the small rack.

[0018] The rotation of the lower motor gear will also drive the internal gear and the card tooth block to rotate through the belt, thereby driving the opening and closing gear to rotate.

[0019] That is, the transmission belt is driven by the small rack to continuously switch and rotate forward and reverse. When the transmission belt first drives the two rotating arms to rotate clockwise by 90 degrees at the same time, it will also drive the shaft-in car to move toward the main frame for feeding. The left rotating claw takes out the motor shaft in the shaft-in car. At this time, the motor shaft is in a vertical state. At this time, the right rotating claw takes out the processed motor shaft. At this time, the processed motor shaft is in a horizontal state; the transmission belt then drives the two rotating arms to rotate counterclockwise by 180 degrees at the same time. At this time, the shaft-in car moves away from the main frame to prepare for the next feeding. The left rotating claw puts the motor shaft into the machine tool for processing. At this time, the motor shaft is in a horizontal state, and the shaft-out car moves toward the main frame to put the motor shaft on the right rotating claw into the shaft-out car for discharging. At this time, the processed motor shaft is in a vertical state.

[0020] Compared with the prior art, the present invention has the following beneficial effects: (1) the feeding mechanism provided in the present invention can continuously feed the motor shaft to be processed, and cooperate with the rotating arm device to clamp the fed motor shaft, and the discharging mechanism can take out the processed motor shaft, which has a high degree of automation; (2) the rotating arm device provided in the present invention can automatically adjust the motor shaft to a horizontal state and place it into the processing bed, and take out the processed motor shaft, thereby realizing automatic loading and unloading; (3) the picking and placing device provided in the present invention can continuously drive the rotating arm device to rotate back and forth, thereby cooperating with the feeding mechanism, the discharging mechanism and the rotating arm device to transfer the motor shaft, and can drive the release and taking of the motor shaft, which has a high degree of automation.

[0038] like Figure 2-Figure 6 As shown, the discharging mechanism includes an axle discharging vehicle 111 slidably mounted on the extending plate 128, a motor frame 113 is fixedly mounted on the axle discharging vehicle 111, a right motor 114 is fixedly mounted on the motor frame 113, a right motor gear 115 is fixedly mounted on the motor shaft of the right motor 114, a fixed column 116 is fixedly mounted on the axle discharging vehicle 111, a lifting column 118 is slidably mounted on the fixed column 116, a right rotating column 117 is rotatably mounted on the lifting column 118, and the right rotating column 117 is fixedly mounted on the right rotating column 117. A right upper gear 120 and a right lower gear 119 are fixedly mounted on the main frame 101, a lifting connecting rod 121 is rotatably mounted on the lifting column 118, a right slider 122 is rotatably mounted on the lifting connecting rod 121, a slide rail 124 is fixedly mounted on the axle-exiting vehicle 111, the right slider 122 is slidably mounted on the slide rail 124, a right connecting rod 123 is fixedly mounted on the right slider 122, the right connecting rod 123 is fixedly mounted on the main frame 101, and a right rack 125 is fixedly mounted on the axle-exiting vehicle 111.

[0039] like Figure 2-Figure 6 As shown, a right roller 112 is rotatably mounted on the axle-exiting vehicle 111 , and a left roller 130 is rotatably mounted in the axle-incoming vehicle 104 .

[0040] Multiple motor shafts to be processed are placed in the shaft input box 103. The motor shafts are tensioned between the feed spring 126 and the inner wall of the shaft input box 103 through the feed plate 127. The weight of the motor shaft is greater than the elastic force of the feed plate 127. Driven by the left rack 110, the shaft input cart 104 slides in the shaft input box 103. When the shaft placement hole 105 reaches the bottom of the motor shaft, since the gravity of the motor shaft is greater than the elastic force of the feed plate 127, the motor shaft falls into the shaft placement hole 105, and as the shaft input cart 104 moves forward, the motor shaft is transported forward.

[0041] like Figure 7-Figure 9As shown, the rotating arm device includes two unlocking frames 214 fixedly mounted on the main frame 101, and two mechanical arm mechanisms are arranged on the main frame 101. The mechanical arm mechanism includes a rotating arm 201 rotatably mounted on the main frame 101, and an upper gear 202 and a lower gear 203 are fixed on the rotating arm 201. A transmission belt 204 is wrapped around the two upper gears 202. The lower gear 203 of the mechanical arm mechanism close to the feeding mechanism side is meshed with the left rack 110, and the lower gear 203 of the mechanical arm mechanism close to the discharging mechanism side is meshed with the right rack 125.

[0042] like Figure 7-Figure 9 As shown, the mechanical arm mechanism also includes a slide 206 fixedly mounted on the rotating arm 201, a tooth block 207 is slidably mounted on the slide 206, a tooth spring 208 is arranged between the tooth block 207 and the slide 206, a rotating gear disc 205 is rotatably mounted on the rotating arm 201, the tooth block 207 cooperates with the rotating gear disc 205, two clamping claws 209 are rotatably mounted on the rotating gear disc 205, a docking gear 213 is rotatably mounted on the rotating gear disc 205, a clamping link 212 is rotatably mounted on the docking gear 213, the clamping link 212 is rotatably mounted with the clamping claw 209, a rotating claw 210 is rotatably mounted on the clamping claw 209, and a spring 211 is arranged between the rotating claw 210 and the clamping claw 209.

[0043] The transmission belt 204 drives the rotating arm 201 and the lower gear 203 near the left rack 110 to rotate clockwise by ninety degrees, thereby driving the left rack 110 to move through the lower gear 203, and the left rack 110 drives the axle feed vehicle 104 to slide inward. Under the action of the unlocking frame 214, the tooth block 207 is lifted, and the tooth spring 208 is compressed. At this time, the tooth block 207 is disengaged from the rotating tooth plate 205, and the rotating tooth plate 205 is meshed with the fixed gear seat 102. Under the action of the fixed gear seat 102, the rotating tooth plate 205 rotates ninety degrees. At this time, the unlocking frame 214 no longer lifts the tooth block 207, and the tooth block 207 is in The tooth spring 208 descends and locks the rotating toothed disc 205. At this time, the clamping claw 209 is in a horizontal state and is located on both sides of the motor shaft in the shaft hole 105. At this time, the docking gear 213 is engaged with the upper left gear 131. The left motor 106 drives the motor gear 107 to rotate, thereby driving the lower left gear 109 and the left vertical shaft 108 to rotate, thereby driving the upper left gear 131 to rotate, thereby driving the docking gear 213 to rotate, thereby driving the clamping link 212 to rotate, driving the clamping claw 209 to tighten, and clamping the motor shaft through the rotating claw 210. The spring 211 is used to keep the rotating claw 210 in contact with the motor shaft.

[0044] Then the transmission belt 204 will reverse and drive the upper gear 202 and the rotating arm 201 to rotate counterclockwise by 180 degrees. Similarly, under the action of the fixed gear seat 102 and the unlocking frame 214, the rotating gear disc 205 rotates 90 degrees, so that the motor shaft is in a horizontal state at this time. At this time, the rotating arm 201 rotates 90 degrees counterclockwise compared to the initial state. At this time, the docking gear 213 is engaged with the opening and closing gear 308. The rotation of the opening and closing gear 308 causes the docking gear 213 to rotate, thereby driving the clamping link 212 to rotate, so that the clamping claw 209 and the rotating claw 210 release the motor shaft. At this time, the motor shaft is located at the main shaft of the processing machine for processing. At this time, the left rack 110 drives the feed shaft car 104 to retreat for the next feeding.

[0045] Since the two rotating arms 201 are oriented in the same direction, when the transmission belt 204 rotates, it will also drive the rotating arm 201 near the axle output vehicle 111 to rotate at the same time. After the motor shaft is processed, the clamping claw 209 on the rotating arm 201 near the axle output vehicle 111 is in a vertical state, and the processed motor shaft is in a horizontal state. The rotation of the opening and closing gear 308 drives the docking gear 213 to rotate, thereby driving the clamping link 212 to rotate, thereby driving the clamping claw 209 and the rotating claw 210 to clamp the processed motor shaft. Subsequently, the transmission belt 204 rotates and drives the rotating arm 201 near the axle output vehicle 111 to rotate 180 degrees counterclockwise. Under the action of the fixed gear seat 102, the clamping claw 209 becomes horizontal, and the motor shaft is in a vertical state.

[0046] At the same time, the rotation of the rotating arm 201 and the lower gear 203 will drive the right rack 125 and the axle-exiting vehicle 111 to slide inward along the extending plate 128, drive the right slider 122 to slide in the slide rail 124, thereby driving the lifting connecting rod 121 to rotate, thereby driving the lifting column 118 to rise along the fixed column 116, driving the right lower gear 119 to mesh with the right motor gear 115, and at this time, the right upper gear 120 is meshed with the docking gear 213 close to the axle-exiting vehicle 111 side, and the motor shaft is located above the columnar hole of the axle-exiting vehicle 111. The rotation of the motor 114 drives the right motor gear 115 to rotate, thereby driving the lower right gear 119 and the right rotating column 117 to rotate, thereby driving the upper right gear 120 to rotate, thereby driving the docking gear 213 to rotate, driving the clamping link 212 to rotate, driving the clamping claw 209 to open, and dropping the motor shaft into the columnar hole of the axle output vehicle 111. As the transmission belt 204 moves in the opposite direction, the axle output vehicle 111 will be driven away from the main frame 101, the lifting column 118 will descend, and the lower right gear 119 will disengage from the right motor gear 115.

[0047] like Figure 10-12As shown, the picking and placing device includes a rotating motor 312 fixedly mounted on the transfer frame 301, a lower motor gear 313 is fixedly mounted on the motor shaft of the rotating motor 312, a turntable 305 and two rotating shafts 307 are rotatably mounted on the transfer frame 301, a tensioning gear 308 and an internal gear 309 are fixedly mounted on the rotating shaft 307, a turntable gear 311 and an eccentric column 306 are fixedly mounted on the turntable 305, the turntable gear 311 is meshed with the lower motor gear 313, a belt 310 is wrapped around the lower motor gear 313 and the two internal gears 309, and a belt rotating mechanism is arranged on the rotating seat 129.

[0048] like Figure 10-12 As shown, the belt transfer mechanism includes a rotating plate 302 rotatably mounted on a rotating seat 129, two sliders 314 are slidably mounted on the rotating plate 302, a small rack 303 is rotatably mounted on the slider 314, a slider spring 315 is provided between the slider 314 and the rotating plate 302, the small rack 303 cooperates with the transmission belt 204, a stand 304 is slidably mounted on the rotating plate 302, and an eccentric column 306 slides in the stand 304.

[0049] The rotating motor 312 drives the lower motor gear 313 to rotate, thereby driving the turntable gear 311 to rotate, thereby driving the turntable 305 to rotate, thereby driving the stand 304 to slide left and right through the eccentric column 306, and at the same time the stand 304 can slide inside and outside relative to the eccentric column 306, thereby driving the rotating plate 302 to rotate relative to the rotating seat 129, and the slider spring 315 makes the small rack 303 always clamped with the transmission belt 204, the small rack 303 can rotate relative to the slider 314, and the rotating plate 302 rotates, which will drive the transmission belt 204 to do continuous forward and reverse switching movements through the small rack 303.

[0050] The rotation of the lower motor gear 313 will also drive the internal gear 309 and the latching tooth block 207 to rotate through the belt 310, thereby driving the opening and closing gear 308 to rotate.

[0051] That is, the transmission belt 204 is driven by the small rack 303 to continuously switch and rotate forward and reverse. When the transmission belt 204 first drives the two rotating arms 201 to rotate ninety degrees clockwise at the same time, it will also drive the shaft-in vehicle 104 to move toward the main frame 101 for feeding. The left rotating claw 210 takes out the motor shaft in the shaft-in vehicle 104. At this time, the motor shaft is in a vertical state. At this time, the right rotating claw 210 takes out the machined motor shaft, and the machined motor shaft is in a horizontal state; the transmission belt 204 then drives the two rotating arms 201 to rotate one hundred and eighty degrees counterclockwise at the same time. At this time, the shaft-in vehicle 104 is away from the main frame 101 to prepare for the next feeding. The left rotating claw 210 puts the motor shaft into the machine tool for processing. At this time, the motor shaft is in a horizontal state, and at this time, the shaft-out vehicle 111 moves toward the main frame 101, and the motor shaft on the right rotating claw 210 is put into the shaft-out vehicle 111 for discharging. At this time, the machined motor shaft is in a vertical state.

[0052] The working principle of the automatic loading and unloading device for motor shaft processing disclosed in the present invention is as follows: the rotating motor 312 drives the lower motor gear 313 to rotate, thereby driving the turntable gear 311 to rotate, thereby driving the turntable 305 to rotate, thereby driving the stand 304 to slide left and right through the eccentric column 306, and at the same time, the stand 304 can slide inside and outside relative to the eccentric column 306, thereby driving the rotating plate 302 to rotate relative to the rotating seat 129, and the small rack 303 is always clamped with the transmission belt 204 through the slider spring 315, and the small rack 303 can rotate relative to the slider 314. The rotating plate 302 rotates, and the transmission belt 204 is driven to perform continuous forward and reverse switching movements through the small rack 303. The rotation of the lower motor gear 313 will also drive the internal gear 309 and the card tooth block 207 to rotate through the belt 310, thereby driving the opening and closing gear 308 to rotate. The transmission belt 204 drives the rotating arm 201 and the lower gear 203 near the left rack 110 to rotate clockwise by ninety degrees, thereby driving the left rack 110 to move through the lower gear 203, and the left rack 110 drives the axle feed vehicle 104 to slide inward. Under the action of the unlocking frame 214, the tooth block 207 is lifted, and the tooth spring 208 is compressed. At this time, the tooth block 207 is disengaged from the rotating tooth plate 205, and the rotating tooth plate 205 is meshed with the fixed gear seat 102. Under the action of the fixed gear seat 102, the rotating tooth plate 205 rotates ninety degrees. At this time, the unlocking frame 214 no longer lifts the tooth block 207, and the tooth block 207 is in The tooth spring 208 descends and locks the rotating toothed disc 205. At this time, the clamping claw 209 is in a horizontal state and is located on both sides of the motor shaft in the shaft hole 105. At this time, the docking gear 213 is engaged with the upper left gear 131. The left motor 106 drives the motor gear 107 to rotate, thereby driving the lower left gear 109 and the left vertical shaft 108 to rotate, thereby driving the upper left gear 131 to rotate, thereby driving the docking gear 213 to rotate, thereby driving the clamping link 212 to rotate, driving the clamping claw 209 to tighten, and clamping the motor shaft through the rotating claw 210. The spring 211 is used to keep the rotating claw 210 in contact with the motor shaft. Multiple motor shafts to be processed are placed in the shaft input box 103, and the motor shafts are tensioned between the feed spring 126 and the inner wall of the shaft input box 103 through the feed plate 127. Driven by the left rack 110, the shaft input cart 104 slides in the shaft input box 103. When the shaft placement hole 105 reaches below the motor shaft, the motor shaft falls into the shaft placement hole 105, and as the shaft input cart 104 moves forward, the motor shaft is transported forward.Then the transmission belt 204 will reverse and drive the upper gear 202 and the rotating arm 201 to rotate counterclockwise by 180 degrees. Similarly, under the action of the fixed gear seat 102 and the unlocking frame 214, the rotating gear disc 205 rotates 90 degrees, so that the motor shaft is in a horizontal state at this time. At this time, the rotating arm 201 rotates 90 degrees counterclockwise compared to the initial state. At this time, the docking gear 213 is engaged with the opening and closing gear 308. The rotation of the opening and closing gear 308 causes the docking gear 213 to rotate, thereby driving the clamping link 212 to rotate, so that the clamping claw 209 and the rotating claw 210 release the motor shaft. At this time, the motor shaft is located at the main shaft of the processing machine for processing. At this time, the left rack 110 drives the feed shaft car 104 to retreat for the next feeding. Since the two rotating arms 201 are oriented in the same direction, when the transmission belt 204 rotates, it will also drive the rotating arm 201 near the axle output vehicle 111 to rotate at the same time. After the motor shaft is processed, the clamping claw 209 on the rotating arm 201 near the axle output vehicle 111 is in a vertical state, and the processed motor shaft is in a horizontal state. The rotation of the opening and closing gear 308 drives the docking gear 213 to rotate, thereby driving the clamping link 212 to rotate, thereby driving the clamping claw 209 and the rotating claw 210 to clamp the processed motor shaft. Subsequently, the transmission belt 204 rotates and drives the rotating arm 201 near the axle output vehicle 111 to rotate 180 degrees counterclockwise. Under the action of the fixed gear seat 102, the clamping claw 209 becomes horizontal, and the motor shaft is in a vertical state. At the same time, the rotation of the rotating arm 201 and the lower gear 203 will drive the right rack 125 and the axle-exiting vehicle 111 to slide inward along the extending plate 128, drive the right slider 122 to slide in the slide rail 124, thereby driving the lifting connecting rod 121 to rotate, thereby driving the lifting column 118 to rise along the fixed column 116, driving the right lower gear 119 to mesh with the right motor gear 115, and at this time, the right upper gear 120 is meshed with the docking gear 213 close to the axle-exiting vehicle 111 side, and the motor shaft is located above the columnar hole of the axle-exiting vehicle 111. The rotation of the motor 114 drives the right motor gear 115 to rotate, thereby driving the lower right gear 119 and the right rotating column 117 to rotate, thereby driving the upper right gear 120 to rotate, thereby driving the docking gear 213 to rotate, driving the clamping link 212 to rotate, driving the clamping claw 209 to open, and dropping the motor shaft into the columnar hole of the axle output vehicle 111. As the transmission belt 204 moves in the opposite direction, the axle output vehicle 111 will be driven away from the main frame 101, the lifting column 118 will descend, and the lower right gear 119 will disengage from the right motor gear 115.

[0053] That is, the transmission belt 204 is driven by the small rack 303 to continuously switch and rotate forward and reverse. When the transmission belt 204 first drives the two rotating arms 201 to rotate ninety degrees clockwise at the same time, it will also drive the shaft-in vehicle 104 to move toward the main frame 101 for feeding. The left rotating claw 210 takes out the motor shaft in the shaft-in vehicle 104. At this time, the motor shaft is in a vertical state. At this time, the right rotating claw 210 takes out the machined motor shaft, and the machined motor shaft is in a horizontal state; the transmission belt 204 then drives the two rotating arms 201 to rotate one hundred and eighty degrees counterclockwise at the same time. At this time, the shaft-in vehicle 104 is away from the main frame 101 to prepare for the next feeding. The left rotating claw 210 puts the motor shaft into the machine tool for processing. At this time, the motor shaft is in a horizontal state, and at this time, the shaft-out vehicle 111 moves toward the main frame 101, and the motor shaft on the right rotating claw 210 is put into the shaft-out vehicle 111 for discharging. At this time, the machined motor shaft is in a vertical state.
