Two sets of slide grooves 720 are opened in the middle of the top of the base 710. The two sets of slide grooves 720 are arranged in a vertical cross shape. The insides of the slide grooves 720 are rotatably connected to bidirectional screw rods 730. The two sets of bidirectional screw rods 730 are also arranged in a cross shape. One bidirectional screw rod 730 is threadedly connected to the inner upper end of one slide groove 720, and the other bidirectional screw rod 730 is threadedly connected to the inner upper end of the other slide groove 720. 30 is threadedly connected to the lower end of the slide groove 720, the threads at both ends of the bidirectional lead screw 730 are rotated in opposite directions, a worm 740 is fixedly installed in the middle of one bidirectional lead screw 730, and a worm wheel 750 is fixedly installed in the middle of the other bidirectional lead screw 730, the worm 740 and the worm wheel 750 are meshingly connected, both ends of the bidirectional lead screw 730 are threadedly connected to a clamping member 760, the lower end of the clamping member 760 is slidably connected to the inside of the slide groove 720, a third motor 770 is fixedly installed on one side of the base 710, and the output end of the third motor 770 is fixedly connected to a bidirectional lead screw 730. There are two sets of adjustment mechanisms 300 in the concave seat 200 on the base 100, which cooperate with the positioning mechanism 700 on the top to achieve accurate positioning and fixation of the bearing, and can flexibly adapt to bearings of different specifications through the cooperation of the worm 740, the worm wheel 750 and the bidirectional screw 730, and have strong adaptability. At the same time, there are stamping mechanisms 500 and lifting mechanisms 600 on the support frame 400 outside the concave seat 200, which can effectively complete the stamping assembly of the bearing.

The slider 761 can achieve precise displacement when the screw rotates through the threaded connection with the bidirectional screw 730, thereby driving the support plate 762 to move, and the fixing block 763 and the clamping frame 764 on the inner side of the support plate 762 can firmly clamp the bearing. This structure can not only ensure the reliability of clamping, but also adapt to bearings of different sizes through the adjustment of the bidirectional screw 730, ensuring the effective fixation and precise operation of the bearing during the assembly process.

Anti-skid plates 765 are fixedly installed on both inner sides of the clamping frame 764, and anti-skid protrusions 766 are fixedly connected to the inner side of the anti-skid plates 765 at equal intervals.

The overall cross-sectional shape of the slider 761 is convex, the cross-sectional shape of the inner section of the slide groove 720 is also convex, and the top view shape of the clamping frame 764 is V-shaped. The convex cross-sectional shape of the slider 761 matches the convex cross-sectional shape of the slide groove 720. This design makes the slider 761 slide more stably and accurately in the slide groove 720, and is not prone to shaking or dislocation, ensuring the precise execution of the clamping action. The clamping frame 764 is V-shaped, which can better fit the shape of the bearing, which is conducive to the stable clamping of the bearing, and this special shape is also helpful to adapt to bearings of different shapes and sizes.

The rack 320 is fixedly installed on the inner front side of the concave seat 200. The inner side of the movable groove 310 is slidably connected with a sliding plate 330. The bottom of the sliding plate 330 is fixedly installed with a driving assembly 340. The upper end of the driving assembly 340 is meshed with the rack 320. The fixed plate 790 is fixedly installed on both sides of the sliding plate 330. The movable groove 310 provides a moving track for the sliding plate 330 to ensure that it can stably slide in the concave seat 200 and achieve accurate position adjustment. The meshing connection between the rack 320 and the driving assembly 340 can accurately control the movement of the sliding plate 330, and the transmission is efficient and stable. The fixed plate 790 is fixedly installed on both sides of the sliding plate 330, so that the positioning mechanism 700 can move flexibly with the sliding plate 330, so that the bearing can be accurately moved to the corresponding position as needed.

The driving assembly 340 includes a fixing frame 341, which is fixedly mounted on the bottom of the sliding plate 330. A first motor 342 is fixedly mounted inside the fixing frame 341. A gear 343 is fixedly mounted on the output end of the first motor 342 through the fixing frame 341. The gear 343 is meshed and connected with the rack 320. The fixing frame 341 provides a stable installation position for the first motor 342 to ensure the stability of the motor when working. The first motor 342 drives the gear 343 to rotate. Through the meshing with the rack 320, the rotational motion of the motor can be converted into the linear movement of the sliding plate 330 in the movable groove 310, realizing the effective transmission and precise control of power. This driving method is simple and efficient, and can quickly and accurately drive the sliding plate 330 and the positioning mechanism 700 thereon to move, adapt to different assembly requirements, and provide a strong guarantee for the smooth assembly of the bearing.

The base 100 is arranged in a rectangular frame shape, and a fixing plate 800 is fixedly installed at each of the four inner corners of the base 100, and a countersunk hole 900 is provided in the middle of the fixing plate 800. The base 100 is in a rectangular frame shape, which provides a stable support foundation for the entire device and ensures the stability of the device during operation. The fixing plates 800 fixedly installed at the four inner corners enhance the stability of the structure, and the countersunk hole 900 provided in the middle facilitates fixed installation, and can firmly fix the device in the desired position, ensuring that it will not shake or shift due to external forces during operation.

The stamping mechanism 500 includes a circular plate 510, which is fixedly mounted on the middle part of the upper end of the support frame 400.

The bottom output end of the hydraulic cylinder 520 penetrates the circular plate 510 and is fixedly mounted with a fixed seat 530. A stamping plate 540 is fixedly mounted on the bottom of the fixed seat 530. The circular plate 510 plays a role in firmly supporting the hydraulic cylinder 520 to ensure the firmness of its installation. The hydraulic cylinder 520 can provide a strong driving force to achieve precise control of the stamping action. Its output end penetrates the circular plate 510 and is connected to the fixed seat 530, thereby driving the stamping plate 540 to perform a downward pressing action. This design makes the stamping process have strong power and accuracy, can efficiently complete the stamping assembly operation of the bearing, and improve work efficiency and quality. At the same time, the entire stamping mechanism 500 has a compact structure and cooperates well with other parts such as the support frame 400, ensuring the reliability and stability of the entire device during the stamping operation.

The lifting mechanism 600 includes a side plate 610, which is fixedly installed at the lower end of one side inside the support frame 400. A second motor 620 is fixedly installed at the bottom of the side plate 610. The output end of the second motor 620 passes through the side plate 610 and is fixedly installed with a one-way screw rod 630. The one-way screw rod 630 is rotatably connected to the side plate 610 and is located between the inner sides of the support frame 400. The outer surface of the one-way screw rod 630 is threadedly connected to a lifting plate 640, and a push plate 650 is fixedly installed at the front end of the lifting plate 640. The side plate 610 provides a stable installation position for the second motor 620 and the one-way screw 630, ensuring the reliability of operation. The second motor 620 drives the one-way screw 630 to rotate, thereby driving the lifting plate 640 threadedly connected thereto to achieve precise lifting and lowering movements. This transmission method is simple, direct and effective. The push plate 650 at the front end of the lifting plate 640 can interact well with other components as the lifting and lowering movements occur, such as a close connection with the positioning mechanism 700, to achieve precise control and coordinated operation of certain steps in the bearing assembly process.

The top of the push plate 650 is rotatably connected with balls 660 at equal intervals, and the top of the balls 660 is closely connected to the bottom of the base 710; the balls 660 at equal intervals on the top of the push plate 650, on the one hand, reduce the friction resistance between the base 710 and the push plate 650, so that the base 710 can move more smoothly under the push of the lifting mechanism 600, improving the fluidity and efficiency of the action. On the other hand, the close connection between the balls 660 and the bottom of the base 710 can provide a more stable support and pushing effect, ensuring the stability of the base 710 during the lifting process, and avoiding shaking or instability.

Principle and advantages of use: By setting up the adjustment mechanism 300, during the use of the device, the bearing to be assembled can be placed inside the positioning mechanism 700, and the bearing can be fixed by operating the positioning mechanism 700. After the bearing is fixed, the first motor 342 can be started to operate, and the first motor 342 drives the gear 343 to rotate, and the gear 343 and the rack 320 are meshed and connected. The rotation of the rack 320 can drive the sliding plate 330 to slide on the inner side of the movable groove 310. The sliding of the sliding plate 330 inside the movable groove 310 can assist in adjusting and driving the bearing to move to the bottom of the stamping mechanism 500. At this time, by starting the hydraulic cylinder 520 to operate, the stamping plate 540 at the bottom of the fixed seat 530 can be driven downward by the hydraulic cylinder 520. The bearing can be contacted by moving the stamping plate 540 downward, and the bearing can be pressed to complete the assembly by squeezing the bearing. During this assembly process, since two sets of adjustment mechanisms 300 and positioning mechanisms 700 are set, one set of positioning mechanisms 700 is located at the bottom of the stamping plate 540 for stamping, while the positioning mechanism 700 located outside can continue to assemble the bearing. After the bearing is assembled, the drive assembly 340 is started again to run. At this time, the bearing located at the bottom of the stamping plate 540 is stamped and pressed, and the pressed bearing is moved out, while the unpressed bearing is moved to the bottom of the stamping plate 540. The two sets of positioning mechanisms 700 are designed to cooperate with each other in an alternating manner, which can carry out continuous and uninterrupted production, thereby improving the overall production and processing efficiency of the device.

By setting the positioning mechanism 700 and the lifting mechanism 600, the device can be used in a specific process. The assembled bearing can be placed on the top of the base 710 and the second motor 620 can be started to run. The third motor 770 drives the bidirectional screw rod 730 to rotate. The rotation of the bidirectional screw rod 730 can drive the slider 761 to slide inside the slide groove 720, and the worm 740 and the worm wheel 750 cooperate with each other for transmission. As the bidirectional screw rod 730 rotates, the worm 740 and the worm wheel 750 can be driven to cooperate with each other, and then the two sets of bidirectional screw rods 730 can be driven to rotate synchronously. The rotation of the two sets of bidirectional screw rods 730 can assist The auxiliary driving slider 761 is located inside the slide groove 720 and reciprocates. At this time, the four groups of sliders 761 all move toward each other, thereby synchronously driving the four groups of support plates 762 to move relative to each other. The movement of the four groups of support plates 762 can drive the clamping frame 764 to move relative to each other. The displacement of the clamping frame 764 can assist in clamping the bearing. The four groups of clamping frames 764 are set to be able to synchronously clamp and position the outer side of the bearing, and the overall clamping has strong stability. In addition, the anti-slip plate 765 and the anti-slip protrusion 766 are set on the inner side of the clamping frame 764, which can play a good anti-slip role, so that the device can clamp and position the bearing more stably. Due to the reciprocating displacement setting of the clamping frame 764, it can stably clamp and position bearings of different sizes and specifications, which can improve the adaptability of the overall positioning and clamping bearing of the device. During the clamping and positioning process, if the height needs to be adjusted, the second motor 620 can be started to run, and the second motor 620 can drive the one-way screw 630 to rotate. The rotation of the one-way screw 630 can assist in driving the lifting plate 640 to move up and down. The lifting and lowering of the lifting plate 640 can drive the push plate 650 to lift the base 710, and the base 710 slides on the outer surface of the support shaft 780, which can enable the device to flexibly adjust its height. Due to the setting of the ball 660, the friction force at the bottom of the base 710 can be increased, which is convenient for adjustment, so that the device as a whole can not only flexibly adjust the clamping adaptability, but also flexibly adjust the adaptability height, and the overall adaptability is strong.
