A connecting hose 305 is provided on the top of the control component, and an adjusting component is provided on the top rear side of the connecting hose 305. The control component relies on the connecting hose 305 to link the adjusting component. The adjusting component is connected to the lower box body 402, and the angle change of the upper box body 403 is controlled by the adjusting component.

[0035] A clamping assembly is provided inside the lower box body 402, and the bottom of the clamping assembly is connected to the connecting hose 305. The clamping assembly can also be synchronously controlled through the connecting hose 305 to achieve positioning and clamping of the bearing, thereby ensuring the stability of the bearing during the cover opening process.

The inner side of each first connecting rod 208 is rotatably connected to the second connecting rod 209. The middle parts of the first connecting rod 208 and the second connecting rod 209 are hinged to each other. The bottom of the first connecting rod 208 is commonly connected to the first cylindrical rod 204. The front and rear ends of the first cylindrical rod 204 are slidably connected to the support plate 201. The front and rear ends of the first cylindrical rod 204 are slidably connected to the internal groove of the support plate 201, which can constrain the first cylindrical rod 204. The rod 204 can only move horizontally left and right. A first connecting block 203 is provided in the middle of the first cylindrical rod 204. A first electric push rod 202 is provided on the left side of the first connecting block 203. The bottom of the first electric push rod 202 is connected to the support plate 201. The first electric push rod 202 can be freely extended and retracted after power is turned on. The extension and retraction of the first electric push rod 202 can drive the first cylindrical rod 204 to move horizontally left and right through the first connecting block 203. The bottom of the second connecting rod 209 is commonly connected to the second cylindrical rod 207. The second cylindrical rod 207 and the second connecting rod 20 9 is rotatably connected, a second connecting block 206 is provided in the middle of the second cylindrical rod 207, a second electric push rod 205 is provided on the right side of the second connecting block 206, the bottom of the second electric push rod 205 is connected to the support plate 201, the front and rear ends of the second cylindrical rod 207 are slidably connected to the support plate 201, the second electric push rod 205 can drive the second connecting block 206 to move left and right, the second connecting block 206 drives the rotatably connected second cylindrical rod 207 to move horizontally inside the support plate 201, and the inner side of the second connecting rod 209 is provided with a two-way extension The retractable rod 215, the top of the bidirectional telescopic rod 215 is connected to the support frame 214, and the bottom of the bidirectional telescopic rod 215 is slidably connected to the support plate 201. When the hinge point position of the first connecting rod 208 and the second connecting rod 209 moves left and right, the support frame 214 can be driven to move left and right. When the height of the hinge point changes, the bidirectional telescopic rod 215 extends or contracts accordingly without affecting other movements of the support frame 214, ensuring that the left and right position of the support frame 214 can change with the change of the hinge point position of the first connecting rod 208 and the second connecting rod 209.

[0037] A second pin 212 is provided on the inner side of the top of the first connecting rod 208, and a second rectangular frame 213 is provided on the inner side of the second pin 212. The inner side of the second rectangular frame 213 is connected to the outer wall of the support frame 214. When the first connecting rod 208 rotates, the second pin 212 on the top can be driven to move in a circle, and the second pin 212 drives the second rectangular frame 213 slidably connected on the outer side to rise or fall. A first pin 210 is provided on the top of the second connecting rod 209, and a first rectangular frame 211 is provided on the inner side of the first pin 210. The inner side of the first rectangular frame 211 is connected to the outer wall of the support frame 214. The second connecting rod 209 rotates to drive the first pin 210 on the top to move in a circle, and the first pin 210 drives the first rectangular frame 211 to rise or fall. When in use, the second electric push rod 205 and the first electric push rod 202 extend at the same time, which can drive the bottom of the first connecting rod 208 and the second connecting rod 209 to move inward at the same time. The top and the top of the second connecting rod 209 move inward at the same time. At this time, the angle between the first connecting rod 208 and the second connecting rod 209 gradually becomes smaller, and the overall height becomes higher. At the same time, the first rectangular frame 211 and the second rectangular frame 213 are lifted up by relying on the first pin 210 and the second pin 212, so that the support frame 214 is lifted up as a whole to complete the adjustment of the bearing height. If the second electric push rod 205 is controlled to shrink alone, the second connecting block 206 can be driven to move to the right, and the bottom of the second connecting rod 209 starts to move to the right. Since the bottom position of the first connecting rod 208 remains unchanged, the angle between the first connecting rod 208 and the second connecting rod 209 gradually increases, the top height is reduced, and the hinge point of the first connecting rod 208 and the second connecting rod 209 moves to the right, so that the support frame 214 is lowered and moved to the right at the same time. Conversely, the support frame 214 can be raised and moved to the left at the same time. Correspondingly, the first electric push rod 202 can also be controlled alone to extend and retract to complete other operations.

The top of the rectangular cylinder 304 is connected to the connecting hose 305, and the connecting hose 305 runs through the support plate 201. When the bottom of the first connecting rod 208 and the second connecting rod 209 move inward at the same time, the height of the support rod 301 increases, driving the limit frame 302 and the piston rod 303 to move upward, so that the gas inside the rectangular cylinder 304 can be discharged through the connecting hose 305.

[0039] The clamping assembly includes a high-pressure hose 312. The bottom of the high-pressure hose 312 is connected to the front end of the connecting hose 305.

A plurality of springs 410 are arranged on the bottom circumference of the limiting rod 405, and the top of the spring 410 is connected to the upper box body 403. When the gas inside the second cylinder 411 is reduced, the limiting rod 405 can be moved downward under the action of the spring 410. At the same time, the four clamping rods 409 rotate outward to contact the fixing of the inner and outer rings of the bearing, and cooperate with the movement of the shift fork to move the bearing to the next process position.

[0040] The regulating component includes a first solenoid valve 306, the right side of the first solenoid valve 306 is interconnected with the connecting hose 305, the first solenoid valve 306 is a prior art, and the on-off state of the valve is adjusted by electric control, and a first cylinder 307 is provided on the left side of the first solenoid valve 306, and the high-pressure gas enters the interior of the first cylinder 307 through the first solenoid valve 306, and the front end of the first cylinder 307 is interconnected with the support plate 201, and the interior of the first cylinder 307 is slidably connected with a first piston 308, and the gas entering the interior of the first cylinder 307 can push the first piston 308 to Move to the left, a first straight rod 309 is provided on the left side of the first piston 308, and a first rack 310 is provided on the left end of the first straight rod 309.

[0041] Specifically: in the normal state, the height of the upper box body 403 is flush with the height of the guide rail 102. At this time, the four clamping rods 409 are in the open state and the limit rod 405 is hidden inside the upper box body 403. The first solenoid valve 306 and the second solenoid valve 401 are both in the closed state. Then the first electric push rod 202 shrinks, the second electric push rod 205 remains stationary, and the left side of the first connecting rod 208 starts to move to the left, pulling the second connecting rod 209 to rotate to the left, so that the angle between the first connecting rod 208 and the second connecting rod 209 becomes larger, and the first connecting rod 208 and The height of the hinge point of the second connecting rod 209 decreases and moves to the left at the same time, so that the support frame 214 decreases in height and moves to the left at the same time, and begins to dock with the right end of the guide rail 102. At the same time, the four clamping rods 409 and the limit rod 405 in the clamping assembly are hidden inside the upper box body 403 and will not interfere with the movement of the bearing. The bearing is connected with the guide rail 102 and the vibration plate 101, and the bearing moves to the surface of the upper box body 403. Then the first electric push rod 202 begins to extend to the initial state, so that the support frame 214 is in the middle of the support plate 201.

[0042] Subsequently, the second electric push rod 205 is controlled separately to extend. During the extension process, the first solenoid valve 306 is controlled to be in a closed state, and the second solenoid valve 401 is in an open state. The bottom of the second connecting rod 209 gradually moves to the left, pushing the first connecting rod 208 to rotate to the left, and the angle between the first connecting rod 208 and the second connecting rod 209 gradually decreases. The middle hinge point position of the first connecting rod 208 and the second connecting rod 209 rises upward and moves to the left at the same time, driving the support frame 214 to move to the left, and at the same time, the position of the support rod 301 also starts to move upward, and part of the gas inside the rectangular tube 304 is first discharged into the second cylinder 411, so that the limit rod 405 is extended and the four clamping rods 409 rotate inward, clamping the inside and outside of the bearing at the same time.

[0043] After the bearing is clamped, the second solenoid valve 401 is closed and the first solenoid valve 306 is opened. As the support frame 214 continues to rise, the internal gas of the rectangular tube 304 begins to enter the first cylinder 307, pushing the first rack 310 to drive the first gear 311 to rotate, and the lower box body 402 and the upper box body 403 are tilted to achieve the following effect. Fig.11 The puncture state shown in the lower part, at this time, the inclination angle of the upper box body 403 is perpendicular to the puncture needle 106, ensuring that the puncture needle 106 can be inserted vertically to ensure the puncture effect of the puncture needle 106, and at the same time, the electric telescopic rod 105 controls the puncture needle 106 to extend and pierce the puncture needle 106 into the interior of the dust cover.

[0044] After the puncture is completed, the second electric push rod 205 begins to actively retract, pulling the second connecting rod 209 to rotate to the right, driving the upper box body 403 to start rotating counterclockwise while moving downward, cooperating with the puncture needle 106 to realize the action of simulating the manual use of the puncture needle 106 to pry the dust cover, so that the puncture needle 106 applies an oblique upward force to the dust cover, and at the same time the upper box body 403 moves downward, further ensuring that the dust cover can be completely separated from the bearing, and then the dust cover can be removed from the puncture needle 106.

[0045] After the cover is opened, the first connecting rod 208 and the second connecting rod 209 return to the Figure 3 The state shown, then the second solenoid valve 401 opens, controlling the first electric push rod 202 and the second electric push rod 205 to contract at the same time, driving the bottom of the first connecting rod 208 and the second connecting rod 209 to move outward at the same time, driving the support frame 214 to move vertically downward, at this time, negative pressure is generated inside the rectangular tube 304 to extract the gas inside the second spring 410, realizing the downward movement of the limit rod 405 and the opening of the four clamping rods 409, thereby releasing the fixation of the bearing.

[0046] Subsequently, the second solenoid valve 401 is closed first, and then the first electric push rod 202 is controlled to extend separately, pushing the bottom of the first connecting rod 208 to move to the right. At this time, the angle between the first connecting rod 208 and the second connecting rod 209 continues to decrease, and the hinge position of the first connecting rod 208 and the second connecting rod 209 begins to move to the right, driving the support frame 214 to rise and move to the right at the same time. At the same time, the internal gas of the rectangular tube 304 gradually enters the first cylinder 307, realizing the clockwise rotation of the lower box body 402 and the upper box body 403, thereby rotating to Fig.11 In a similar tilted state, and at this time, due to the closure of the second solenoid valve 401, the bearing is no longer clamped, and the right end of the upper box body 403 begins to contact the left end of the left conveying plate 107. Under the action of gravity, the bearing will slide along the tilted upper box body 403, and then rely on the shift fork to push the bearing into the block 109, and cooperate with the flip cylinder 108 to complete the flipping of the bearing, thereby realizing the double-sided cover of the bearing.

[0047] It should be noted that, by means of the telescopic assembly, the control assembly and the clamping assembly, the support frame 214 is lowered in height and moved to the left at the same time, so as to dock with the right end of the guide rail 102. At the same time, the four clamping rods 409 and the limit rod 405 in the clamping assembly are hidden inside the upper box body 403, and will not interfere with the movement of the bearing. The bearing connection is completed in cooperation with the guide rail 102 and the vibration plate 101. By controlling the second electric push rod 205 alone, the middle hinge point position of the first connecting rod 208 and the second connecting rod 209 is raised upward and moved to the left at the same time, thereby driving the support frame 214 to move to the left. By cooperating with the control assembly and the clamping assembly, the limit rod 405 is extended and the four clamping rods 409 are rotated inwardly, so as to clamp the inside and outside of the bearing at the same time. Subsequently, the telescopic assembly, the control assembly and the adjustment assembly cooperate to make the lower box body 402 and the upper box body 403 become inclined. The inclination angle of the upper box body 403 is perpendicular to the puncture needle 106, so as to ensure that the puncture needle 106 can be inserted vertically. , to ensure the puncture effect of the puncture needle 106. After the puncture is completed, the second electric push rod 205 begins to actively retract, pulling the second connecting rod 209 to rotate to the right, driving the upper box body 403 to start rotating counterclockwise while moving downward, cooperating with the puncture needle 106 to simulate the action of manually prying the dust cover with the puncture needle 106, so that the puncture needle 106 applies an oblique upward force to the dust cover, and at the same time the upper box body 403 moves downward, further ensuring that the dust cover can be completely separated from the bearing. After the cover is pulled, Through the cooperation of the telescopic component, the control component, the adjustment component and the clamping component, the limit rod 405 moves downward and the four clamping rods 409 are opened, the bearing is released, and the support frame 214 is driven to rise and move to the right side, realizing the clockwise rotation of the lower box body 402 and the upper box body 403. The right end of the upper box body 403 begins to contact the left end of the left conveying plate 107. Under the action of gravity, the bearing will slide along the inclined upper box body 403, completing the unloading operation after the bearing cover is opened.
