Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of bearing assembly equipment, and in particular relates to an automatic assembly device for bearing balls. Background Art
[0002] Bearing ball assembly refers to the process of assembling the ball of the ball bearing with parts such as the inner and outer rings. This process requires certain skills and methods to ensure that the quality and performance of the bearing after assembly meet the requirements. On the production line, bearing assembly is usually completed by automated equipment. Automatic assembly lines can achieve large-scale production and consistent assembly quality through precise control and efficient operation. However, the bearing ball assembly device in the prior art usually uses the transfer principle to abut the balls, but it is usually impossible to achieve fully automatic processing of the bearing and automatic feeding of the bearing balls, resulting in the inability to perform fully automatic feeding and assembly of the bearing balls. At the same time, the pressing of the balls must ensure the integrity of the pressing. Summary of the invention

[0006] Furthermore, the extrusion device includes a lower rack fixedly mounted on the slide, the lower rack is meshed with the transfer gear, a spiral motor is fixedly mounted on the slide, a right spiral column and a left spiral column are rotatably mounted on the slide, a right gear is fixedly mounted on the right spiral column, a left gear and a left bevel gear are fixedly mounted on the left spiral column, the right gear is meshed with the left gear, the slide and the lower screw form a threaded transmission, and the thread directions of the right spiral column and the left spiral column are opposite.
[0007] The rotation of the spiral motor drives the right spiral column to rotate, thereby driving the left gear to rotate through the right gear, thereby driving the left spiral column to rotate. The right spiral column and the left spiral column rotate in opposite directions, transporting the steel balls in the direction away from the spiral motor.
[0008] Furthermore, the bead feeding device includes a vertical screw rod rotatably mounted on the vertical frame, a lifting motor is fixedly mounted on the vertical frame, a motor shaft of the lifting motor is fixedly mounted on the vertical screw rod, a side docking wheel is fixedly mounted on the vertical screw rod, a short rotating shaft is rotatably mounted on the vertical frame, an upper docking wheel and a lower bevel gear are fixedly mounted on the short rotating shaft, the lower bevel gear is meshed with the bevel gear of the screw rod, a short transmission belt is wrapped around the upper docking wheel and the side docking wheel, and a lifting mechanism and a bead storage mechanism are provided on the vertical frame.
[0009] Furthermore, the lifting mechanism includes a bead loading rack slidably mounted in the vertical frame, a top block and a bead loading plate are fixedly mounted on the bead loading rack, steel balls are placed in the bead loading plate, a push slide column is slidably mounted on the bead loading rack, an outward push block is fixedly mounted on the push slide column, an outward push spring is arranged between the outward push block and the bead loading rack, and a bead ejecting mechanism is arranged on the bead loading rack.
[0010] Furthermore, the bead discharge mechanism includes a top plate fixedly mounted on the bead loading rack, a bead pressing block is slidably mounted on the bead loading rack, a bidirectional screw is rotatably mounted on the bead loading rack and the top plate, a docking bevel gear is fixedly mounted on the bidirectional screw, the bidirectional screw and the bead pressing block form a threaded transmission, and the docking bevel gear meshes with the left bevel gear after it drops to the lowest point.
[0011] Furthermore, the bead storage mechanism includes a top frame fixed on the vertical frame, a bead storage frame is fixedly installed on the top frame, a sliding column is fixedly installed on the bead storage frame, a blocking plate is slidably installed on the sliding column, a top opening column is fixedly installed on the blocking plate, a sliding column spring is arranged between the blocking plate and the sliding column, and steel balls are placed in the bead storage frame.
[0012] In the initial state, the blocking plate blocks the steel balls in the bead storage rack, and the sliding column spring is in a normal state. The rotation of the lifting motor drives the vertical screw rod to rotate, thereby driving the bead loading rack to rise. When the top block rises and contacts the top opening column, it drives the top opening column to rise along the sliding column, and the sliding column spring is compressed. The blocking plate no longer blocks the bead storage rack, and the steel balls in the bead storage rack fall into the bead loading plate. When the vertical screw rod drives the bead loading rack to descend, the top block separates from the top opening column, and the blocking plate closes the bead storage rack again under the rebound action of the sliding column spring, and a slope is provided on the blocking plate to facilitate pushing away the steel balls under the blocking plate. When the bead loading rack descends to the bottom, the docking bevel gear begins to mesh with the left bevel gear, and the spiral motor rotates at this time. At the same time, the left bevel gear will drive the docking bevel gear to rotate, and the rotation of the docking bevel gear will drive the two-way screw to rotate, thereby driving the bead pressing block to descend. The bead pressing block descends and pushes the push-out block outward, and the push-out spring is compressed. A slope is provided on the bead loading plate. When the push-out block is stretched open, the steel ball rolls between the two push-out blocks, and the bead pressing block continues to descend, pushing the steel ball between the right spiral column and the left spiral column, and the steel ball is transported forward through the right spiral column and the left spiral column. Every time the right spiral column and the left spiral column rotate a full circle, the two-way screw drives the bead pressing block to complete a lift, that is, a steel ball falls onto the right spiral column and the left spiral column, until a steel ball is placed on each circle of thread on the right spiral column and the left spiral column.
[0013] The rotation of the vertical screw rod will drive the side docking wheel to rotate, thereby driving the upper docking wheel and the lower bevel gear to rotate through the short transmission belt, thereby driving the screw bevel gear and the lower screw rod to rotate, thereby driving the slide to slide along the main frame.
[0014] When the bead loading rack rises, the slide slides in the direction away from the vertical rack. When the bead loading rack moves to the top, the slide moves to the innermost side. At this time, the steel balls are pressed onto the bearings through the right and left spiral columns. At the same time, the bead storage rack puts the steel balls into the bead loading plate. When the bead loading rack descends, the slide slides in the direction of the vertical rack. Because the lower ends of the lower screw rod and the vertical screw rod have non-threaded sections, when the slide moves to the outermost side and the bead loading rack moves to the lower end, the bead loading rack and the lower screw rod continue to rotate and will no longer drive the slide and the bead loading rack to move. At this time, only the left bevel gear drives the docking bevel gear and the right spiral column to rotate. At this time, the bead loading plate puts the steel balls on the right and left spiral columns.
[0015] Furthermore, the steering device includes a descending frame slidably mounted on the vertical sliding column, a descending rack fixedly mounted on the descending frame, the descending rack meshing with the upper gear, a top column fixedly mounted on the descending frame, a steering electric cylinder fixedly mounted on the descending frame, a descending frame fixedly mounted on the top of the steering electric cylinder, the descending frame and the descending frame are slidably mounted, a lead screw is rotatably mounted in the descending frame by a thread, a return spring is arranged between the descending sliding column and the descending frame, the descending sliding column is fixedly mounted on the lead screw, a steering rod is fixedly mounted on the lead screw, a steering fork block is fixedly mounted on the steering rod, an upper turntable is rotatably mounted on the descending frame, a lower turntable is rotatably mounted on the steering rod, and a steering spring is arranged between the upper turntable and the lower turntable.
[0016] Furthermore, the clamping device includes an upper rack fixedly mounted on the sliding block, the upper rack meshing with the intermediate gear, the sliding block is fixedly mounted with a fixing frame, the fixing frame is provided with a clamping mechanism, the main frame is fixedly mounted with a top motor, the main frame is rotatably mounted with a clamping screw, the clamping screw is fixedly mounted with a motor shaft of the top motor, a lower pressing frame is slidably mounted on the upper sliding column, the lower pressing frame and the clamping screw form a threaded transmission, a lower pressing column is fixedly mounted on the lower pressing frame, two side frames are fixedly mounted on the lower column, two groups of telescopic frames are slidably mounted on the side frames, a clamping spring is provided between the telescopic frame and the side frames, a rotating column is rotatably mounted on the telescopic frame, a rotating circle gear is fixedly mounted on the rotating column, a toggle motor is fixedly mounted on the side frame, a motor gear is fixedly mounted on the motor shaft of the toggle motor, the motor gear meshes with the rotating circle gear, and a fixing ring is placed between the four rotating columns.
[0017] Furthermore, the clamping mechanism includes an inner rotating motor fixedly mounted on a fixed frame, an inner rotating disk is rotatably mounted on the fixed frame, a triangular rotating block is fixedly mounted on the motor shaft of the inner rotating motor, an inner clamping rod is slidably mounted on the inner rotating disk, a clamping spring is arranged between the inner clamping rod and the inner rotating disk, and an inner ring of a bearing is placed outside the inner clamping rod.
[0018] The inner ring of the bearing is placed on the inner turntable. The rotation of the inner rotating motor drives the triangular rotating block to rotate, thereby driving the inner clamping rod to slide along the inner turntable. The clamping spring is compressed, and the inner ring of the bearing is tightened by the inner clamping rod. The fixed ring is divided into upper and lower parts. The two parts are placed between the rotating columns. The rotation of the dial motor drives the motor gear to rotate, thereby driving the rotating circle gear and the rotating column to rotate, thereby driving the fixed ring to rotate. When the hole of the fixed ring rotates to the front of the positioning electric cylinder, the positioning electric cylinder will extend and extend into the hole of the fixed ring, thereby locating the hole position of the fixed ring. Then the positioning electric cylinder contracts, and the rotation of the top motor drives the pressing screw to rotate, thereby driving the lower pressure frame to descend along the upper sliding column, and the two fixing rings are pressed onto the inner turntable and the outside of the inner ring of the bearing through the fixing ring, and the two parts of the fixing ring are pressed into a whole. The fixing ring is rotatable relative to the inner ring of the bearing.
[0019] When the slide frame slides along the main frame, it will drive the intermediate gear to rotate through the lower rack, thereby driving the slider and the inner turntable to slide along the main frame, thereby bringing the right spiral column and the fixed frame to the middle at the same time, and finally the right spiral column reaches the front of the fixed ring. At the same time, the rotation of the intermediate gear will drive the gear shaft to rotate, thereby driving the lower wheel to rotate, thereby driving the upper gear and the upper wheel to rotate through the vertical transmission belt, thereby driving the descending rack and the descending frame to descend along the vertical sliding column, thereby driving the top column to press the fixed ring, and the rotation of the inner rotating motor drives the triangular rotating block to rotate, thereby driving the inner clamping rod to rotate. Since the inner clamping rod tightens the inner ring of the bearing, the rotation of the triangular rotating block will drive the inner ring of the bearing to rotate, while the fixed ring does not rotate at this time, and at the same time, the right spiral column and the left spiral column squeeze the steel balls into the holes of the fixed ring.
[0020] When a steel ball enters the fixed ring, the steering electric cylinder descends, driving the lowering frame to descend, and the return spring is compressed. When the steering fork block contacts the fixed ring, the steering electric cylinder continues to extend, which will drive the screw rod to rotate relative to the lowering frame, and the steering spring begins to be compressed, thereby driving the steering rod and the steering fork block to rotate, thereby driving the fixed ring to rotate through the steering fork block, aligning the next hole to be squeezed into the steel ball, and installing the next steel ball. After the rotation of the fixed ring is completed, the steering electric cylinder contracts, driving the steering rod and the steering fork block to rise. Under the action of the steering spring and the return spring, the steering rod and the lowering frame return to their initial positions.
[0021] Compared with the prior art, the present invention has the following beneficial effects: (1) The present invention adopts a combination of a ball feeding device and an extrusion device, through which steel balls can be fed into the ball feeding device and installed into the bearing. When the steel balls are installed into the bearing, the ball feeding device replenishes the steel balls from the ball storage rack, and the degree of automation is high; (2) The present invention can efficiently press the steel balls into the bearing fixing ring by combining the right spiral column and the left spiral column, and at the same time cooperate with the rotation of the bearing inner ring to prevent the steel balls from affecting the rotation relationship between the bearing inner ring and the bearing fixing ring during the pressing process; (3) The present invention uses the top column of the steering device to ensure that the bearing fixing ring will not rotate when the bearing inner ring rotates, thereby preventing the fixing ring from rotating during the squeezing process of the steel balls.

[0036] like Figure 3 As shown, the frame device includes a positioning electric cylinder 103 fixedly mounted on the main frame 101, an upper sliding column 104 and a lower column 105 are fixedly mounted on the main frame 101, a lower screw rod 107 is rotatably mounted on the main frame 101, a screw bevel gear 108 is fixedly mounted on the lower screw rod 107, a gear shaft 109 is rotatably mounted on the main frame 101, a transfer gear 106 and a lower wheel 110 are fixedly mounted on the gear shaft 109, an upper wheel 113 is rotatably mounted on the main frame 101, an upper gear 112 is fixedly mounted on the upper wheel 113, and a vertical transmission belt 111 is wrapped around the upper gear 112 and the lower wheel 110.

[0038] The screw motor 208 rotates to drive the right screw column 203 to rotate, thereby driving the left gear 206 to rotate through the right gear 205, thereby driving the left screw column 204 to rotate. The right screw column 203 and the left screw column 204 rotate in opposite directions, transporting the steel ball 311 in a direction away from the screw motor 208.
[0039] like Figure 6 , Figure 7As shown, the bead feeding device includes a vertical screw rod 307 rotatably mounted on the vertical frame 301, a lifting motor 308 is fixedly mounted on the vertical frame 301, the motor shaft of the lifting motor 308 is fixedly mounted on the vertical screw rod 307, a side docking wheel 306 is fixedly mounted on the vertical screw rod 307, a short rotating shaft 302 is rotatably mounted on the vertical frame 301, an upper docking wheel 303 and a lower bevel gear 304 are fixedly mounted on the short rotating shaft 302, the lower bevel gear 304 is meshed with the screw bevel gear 108, a short transmission belt 305 is wrapped around the upper docking wheel 303 and the side docking wheel 306, and a lifting mechanism and a bead storage mechanism are provided on the vertical frame 301.
[0040] like Figure 6 , Figure 7 As shown, the lifting mechanism includes a bead loading frame 309 slidably mounted in the vertical frame 301, a top block 310 and a bead loading plate 312 are fixedly mounted on the bead loading frame 309, a steel ball 311 is placed in the bead loading plate 312, a push slide 315 is slidably mounted on the bead loading frame 309, an outward push block 313 is fixedly mounted on the push slide 315, an outward push spring 314 is arranged between the outward push block 313 and the bead loading frame 309, and a bead discharge mechanism is arranged on the bead loading frame 309.
[0041] like Figure 6 , Figure 7 As shown, the bead discharging mechanism includes a top plate 322 fixedly mounted on the bead loading frame 309, a bead pressing block 323 is slidably mounted on the bead loading frame 309, a bidirectional screw rod 324 is rotatably mounted on the bead loading frame 309 and the top plate 322, a docking bevel gear 325 is fixedly mounted on the bidirectional screw rod 324, the bidirectional screw rod 324 and the bead pressing block 323 form a threaded transmission, and the docking bevel gear 325 is meshed with the left bevel gear 207 after it drops to the lowest point.
[0042] like Figure 6 , Figure 7 As shown, the bead storage mechanism includes a top frame 316 fixed on the vertical frame 301, a bead storage frame 317 is fixedly installed on the top frame 316, a sliding column 320 is fixedly installed on the bead storage frame 317, a blocking plate 319 is slidably installed on the sliding column 320, a top opening column 318 is fixedly installed on the blocking plate 319, a sliding column spring 321 is arranged between the blocking plate 319 and the sliding column 320, and steel balls 311 are placed in the bead storage frame 317.
[0043] In the initial state, the blocking plate 319 blocks the steel balls 311 in the bead storage rack 317, and the slide column spring 321 is in a normal state. The lifting motor 308 rotates to drive the vertical screw rod 307 to rotate, thereby driving the bead loading rack 309 to rise. When the top block 310 rises and contacts the top opening column 318, it drives the top opening column 318 to rise along the slide column 320. The slide column spring 321 is compressed. The blocking plate 319 no longer blocks the bead storage rack 317, and the steel balls 311 in the bead storage rack 317 fall. When the bead loading frame 309 is lowered by the vertical screw rod 307, the top block 310 is separated from the top opening column 318, and the blocking plate 319 closes the bead storage frame 317 again under the rebound action of the sliding column spring 321, and the blocking plate 319 is provided with a slope to facilitate pushing away the steel balls 311 under the blocking plate 319. When the bead loading frame 309 is lowered to the bottom, the docking bevel gear 325 begins to mesh with the left bevel gear 207. At this time, the screw motor 20 The rotation of the left bevel gear 207 will drive the docking bevel gear 325 to rotate at the same time. The rotation of the docking bevel gear 325 drives the two-way screw rod 324 to rotate, thereby driving the bead pressing block 323 to descend. The bead pressing block 323 descends to push the push block 313 outward, the push spring 314 is compressed, and the bead loading plate 312 is provided with a slope. When the push block 313 is stretched open, the steel ball 311 rolls between the two push blocks 313, and the bead pressing block 323 continues to descend, pushing the steel ball 311 outward. When the right and left spiral columns 203 and 204 rotate one full circle, the bidirectional screw rod 324 drives the bead pressing block 323 to complete a lifting, that is, a steel ball 311 falls onto the right and left spiral columns 203 and 204, until a steel ball 311 is placed on each circle of the right and left spiral columns 203 and 204.
[0044] The rotation of the vertical screw rod 307 will drive the side docking wheel 306 to rotate, thereby driving the upper docking wheel 303 and the lower bevel gear 304 to rotate through the short transmission belt 305, thereby driving the screw bevel gear 108 and the lower screw rod 107 to rotate, thereby driving the slide 201 to slide along the main frame 101.
[0045] When the bead loading rack 309 rises, the slide 201 slides in the direction away from the vertical rack 301. When the bead loading rack 309 moves to the top, the slide 201 moves to the innermost side. At this time, the steel ball 311 is pressed onto the bearing through the right spiral column 203 and the left spiral column 204. At the same time, the bead storage rack 317 puts the steel ball 311 into the bead loading plate 312. When the bead loading rack 309 descends, the slide 201 slides in the direction of the vertical rack 301, and due to the lower screw rod 10 7 and the lower ends of the vertical screw rod 307 both have non-threaded sections. When the slide 201 moves to the outermost side and the bead loading rack 309 moves to the lowermost side, the bead loading rack 309 and the lower screw rod 107 continue to rotate and will no longer drive the slide 201 and the bead loading rack 309 to move. At this time, only the left bevel gear 207 drives the docking bevel gear 325 and the right spiral column 203 to rotate. At this time, the bead loading plate 312 puts the steel balls 311 on the right spiral column 203 and the left spiral column 204.
[0046] like Figure 8-Figure 10 As shown, the steering device includes a descending frame 401 slidably mounted on the vertical sliding column 102, a descending rack 402 is fixedly mounted on the descending frame 401, and the descending rack 402 is meshed with the upper gear 112.

[0048] like Fig.11 , Fig.12 As shown, the clamping mechanism includes an inner rotating motor 504 fixedly mounted on a fixed frame 503, an inner rotating disk 505 is rotatably mounted on the fixed frame 503, a triangular rotating block 506 is fixedly mounted on the motor shaft of the inner rotating motor 504, an inner clamping rod 507 is slidably mounted on the inner rotating disk 505, a clamping spring 508 is arranged between the inner clamping rod 507 and the inner rotating disk 505, and a bearing inner ring 520 is placed outside the inner clamping rod 507.
[0049] The inner ring 520 of the bearing is placed on the inner turntable 505. The inner rotating motor 504 rotates to drive the triangular rotating block 506 to rotate, thereby driving the inner clamping rod 507 to slide along the inner turntable 505. The clamping spring 508 is compressed, and the inner ring 520 of the bearing is tightened by the inner clamping rod 507. The fixed ring 521 is divided into two parts, the upper and lower parts, and the two parts are placed between the rotating columns 519. The rotating motor 514 rotates to drive the motor gear 515 to rotate, thereby driving the rotating circle gear 516 and the rotating column 519 to rotate, thereby driving the fixed ring 521 to rotate. When the hole of the fixed ring 521 rotates The electric cylinder 103 moves to the front of the positioning cylinder 103, and the positioning cylinder 103 extends to extend into the hole of the fixing ring 521, thereby positioning the hole position of the fixing ring 521, and then the positioning cylinder 103 contracts, and the top motor 509 rotates to drive the pressing screw 510 to rotate, thereby driving the lower pressing frame 511 to descend along the upper sliding column 104, and the two fixing rings 521 are pressed onto the inner turntable 505 and the outer side of the bearing inner ring 520 through the fixing ring 521, and the two parts of the fixing ring 521 are pressed into a whole, and the fixing ring 521 is rotatable relative to the bearing inner ring 520.
[0050] When the slide 201 slides along the main frame 101, the transfer gear 106 is driven to rotate through the lower rack 202, thereby driving the slider 501 and the inner turntable 505 to slide along the main frame 101, thereby driving the right spiral column 203 and the fixed frame 503 to move toward the middle at the same time, and finally the right spiral column 203 arrives in front of the fixed ring 521. At the same time, the rotation of the transfer gear 106 drives the gear shaft 109 to rotate, thereby driving the lower wheel 110 to rotate, thereby driving the upper gear 112 and the upper wheel 113 to rotate through the vertical transmission belt 111. Thereby, the descending rack 402 and the descending frame 401 are driven to descend along the vertical sliding column 102, thereby driving the top column 411 to press the fixing ring 521, and the inner rotating motor 504 rotates to drive the triangular rotating block 506 to rotate, thereby driving the inner clamping rod 507 to rotate. Since the inner clamping rod 507 tightens the inner ring 520 of the bearing, the rotation of the triangular rotating block 506 will drive the inner ring 520 of the bearing to rotate, while the fixing ring 521 does not rotate at this time. At the same time, the right spiral column 203 and the left spiral column 204 squeeze the steel ball 311 into the hole of the fixing ring 521.
[0051] When a steel ball 311 enters the fixing ring 521, the steering electric cylinder 403 descends, driving the descending frame 404 to descend, and the return spring 406 is compressed. When the steering fork block 410 contacts the fixing ring 521, the steering electric cylinder 403 continues to extend, which will drive the screw rod 407 to rotate relative to the descending frame 404, and the steering spring 408 begins to be compressed, thereby driving the steering rod 409 and the steering fork block 410 to rotate, thereby driving the fixing ring 521 to rotate through the steering fork block 410, aligning the next hole to be squeezed into with the steel ball 311, and installing the next steel ball 311. After the rotation of the fixing ring 521 is completed, the steering electric cylinder 403 contracts, driving the steering rod 409 and the steering fork block 410 to rise, and under the action of the steering spring 408 and the return spring 406, the steering rod 409 and the descending frame 404 return to their initial positions.
[0052] The working principle of this embodiment is as follows: the inner ring 520 of the bearing is placed on the inner rotating disk 505, the inner rotating motor 504 rotates to drive the triangular rotating block 506 to rotate, thereby driving the inner clamping rod 507 to slide along the inner rotating disk 505, the clamping spring 508 is compressed, and the inner ring 520 of the bearing is tightened by the inner clamping rod 507, the fixed ring 521 is divided into two parts, the upper and lower parts are placed between the rotating columns 519, the rotating motor 514 rotates to drive the motor gear 515 to rotate, thereby driving the rotating circle gear 516 and the rotating column 519 to rotate, thereby driving the fixed ring 521 to rotate, when the fixed ring 5 The hole of 21 rotates to the front of the positioning electric cylinder 103, and the positioning electric cylinder 103 extends to extend into the hole of the fixing ring 521, thereby positioning the hole position of the fixing ring 521, and then the positioning electric cylinder 103 contracts, and the top motor 509 rotates to drive the pressing screw 510 to rotate, thereby driving the lower pressing frame 511 to descend along the upper sliding column 104, and the two fixing rings 521 are pressed onto the inner turntable 505 and the outer side of the bearing inner ring 520 through the fixing ring 521, and the two parts of the fixing ring 521 are pressed into a whole, and the fixing ring 521 is rotatable relative to the bearing inner ring 520.In the initial state, the blocking plate 319 blocks the steel balls 311 in the bead storage rack 317, and the slide column spring 321 is in a normal state. The lifting motor 308 rotates to drive the vertical screw rod 307 to rotate, thereby driving the bead loading rack 309 to rise. When the top block 310 rises and contacts the top opening column 318, it drives the top opening column 318 to rise along the slide column 320. The slide column spring 321 is compressed. The blocking plate 319 no longer blocks the bead storage rack 317, and the steel balls 311 in the bead storage rack 317 fall into the bead loading plate 312. When the vertical screw rod 307 drives the loading rack When the bead rack 309 descends, the top block 310 separates from the top opening column 318, and the blocking plate 319 closes the bead storage rack 317 again under the rebound action of the sliding column spring 321, and a slope is provided on the blocking plate 319 to facilitate pushing away the steel balls 311 under the blocking plate 319. When the bead loading rack 309 descends to the bottom, the docking bevel gear 325 begins to mesh with the left bevel gear 207. At this time, the rotation of the spiral motor 208 will simultaneously drive the docking bevel gear 325 to rotate through the left bevel gear 207, and the rotation of the docking bevel gear 325 will drive The movable bidirectional screw rod 324 rotates, thereby driving the bead pressing block 323 to descend. The bead pressing block 323 descends to push the push block 313 outward, the push spring 314 is compressed, and a slope is provided on the bead loading plate 312. When the push block 313 is stretched open, the steel ball 311 rolls between the two push blocks 313, and the bead pressing block 323 continues to descend, pushing the steel ball 311 between the right spiral column 203 and the left spiral column 204. The spiral motor 208 rotates to drive the right spiral column 203 to rotate, thereby driving the left gear 206 through the right gear 205. The right spiral column 203 and the left spiral column 204 rotate in opposite directions, and the steel ball 311 is transported forward by the right spiral column 203 and the left spiral column 204. Every time the right spiral column 203 and the left spiral column 204 rotate a full circle, the bidirectional screw rod 324 drives the bead pressing block 323 to complete a lifting, that is, a steel ball 311 falls onto the right spiral column 203 and the left spiral column 204, until a steel ball 311 is placed on each circle of thread on the right spiral column 203 and the left spiral column 204.
[0053] The rotation of the vertical screw rod 307 will drive the side docking wheel 306 to rotate, thereby driving the upper docking wheel 303 and the lower bevel gear 304 to rotate through the short transmission belt 305, thereby driving the screw bevel gear 108 and the lower screw rod 107 to rotate, thereby driving the slide 201 to slide along the main frame 101. When the bead loading frame 309 rises, the slide 201 slides in the direction away from the vertical frame 301. When the bead loading frame 309 moves to the top, the slide 201 moves to the innermost side. At this time, the steel ball 311 is pressed onto the bearing through the right spiral column 203 and the left spiral column 204, and the bead storage frame 317 puts the steel ball 311 into the bead loading plate 312. When the bead loading frame 309 descends, the slide 201 slides in the direction of the vertical frame 301, and because the lower screw rod 10 7 and the lower ends of the vertical screw rod 307 both have non-threaded sections. When the slide 201 moves to the outermost side and the bead loading rack 309 moves to the lowermost side, the bead loading rack 309 and the lower screw rod 107 continue to rotate and will no longer drive the slide 201 and the bead loading rack 309 to move. At this time, only the left bevel gear 207 drives the docking bevel gear 325 and the right spiral column 203 to rotate. At this time, the bead loading plate 312 puts the steel balls 311 on the right spiral column 203 and the left spiral column 204. When the slide 201 slides along the main frame 101, the transfer gear 106 is driven to rotate through the lower rack 202, thereby driving the slider 501 and the inner turntable 505 to slide along the main frame 101, thereby driving the right spiral column 203 and the fixed frame 503 to move toward the middle at the same time, and finally the right spiral column 203 arrives in front of the fixed ring 521. At the same time, the rotation of the transfer gear 106 drives the gear shaft 109 to rotate, thereby driving the lower wheel 110 to rotate, thereby driving the upper gear 112 and the upper wheel 113 to rotate through the vertical transmission belt 111. Thereby, the descending rack 402 and the descending frame 401 are driven to descend along the vertical sliding column 102, thereby driving the top column 411 to press the fixing ring 521, and the inner rotating motor 504 rotates to drive the triangular rotating block 506 to rotate, thereby driving the inner clamping rod 507 to rotate. Since the inner clamping rod 507 tightens the inner ring 520 of the bearing, the rotation of the triangular rotating block 506 will drive the inner ring 520 of the bearing to rotate, while the fixing ring 521 does not rotate at this time. At the same time, the right spiral column 203 and the left spiral column 204 squeeze the steel ball 311 into the hole of the fixing ring 521.When a steel ball 311 enters the fixing ring 521, the steering electric cylinder 403 descends, driving the descending frame 404 to descend, and the return spring 406 is compressed. When the steering fork block 410 contacts the fixing ring 521, the steering electric cylinder 403 continues to extend, which will drive the screw rod 407 to rotate relative to the descending frame 404, and the steering spring 408 begins to be compressed, thereby driving the steering rod 409 and the steering fork block 410 to rotate, thereby driving the fixing ring 521 to rotate through the steering fork block 410, aligning the next hole to be squeezed into with the steel ball 311, and installing the next steel ball 311. After the rotation of the fixing ring 521 is completed, the steering electric cylinder 403 contracts, driving the steering rod 409 and the steering fork block 410 to rise, and under the action of the steering spring 408 and the return spring 406, the steering rod 409 and the descending frame 404 return to their initial positions.
