Description

Technical Field

[0001] This utility model belongs to the field of bearing processing technology, specifically a servo press for bearings. Background Technology

[0002] Bearings are an important component in modern mechanical equipment. They are precision mechanical elements that reduce friction loss. Press machines are used in the processing and pressing of bearings, and the effect of bearing pressing directly affects the performance and lifespan of vehicles or equipment.

[0003] A Chinese patent with authorization announcement number CN221494946U discloses a press for bearing installation. This utility model features a sliding groove on the inner wall of the worktable, through which guide rods are fixed. When the hydraulic press is working, a limiting rod on the surface of the pressure plate is movably embedded on the outer surface of the guide rods, thereby limiting the overall position of the pressure plate. Simultaneously, a spring is fixedly installed on one side of the limiting rod, and another side of the spring is fixedly installed on the surface of the sliding groove. This provides shock absorption when the pressure plate applies pressure to the bearing, reducing wear on parts during bearing processing and thus improving the overall service life of the device.

[0004] However, the above solution still has some problems. The lack of fixed bearing position leads to uneven distribution of pressing force due to bearing displacement or tilting during the pressing process, which in turn causes damage to the shaft. Therefore, a servo press for bearings is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and address the problems of existing equipment, this utility model proposes a servo press for bearings.

[0006] The technical solution adopted by this utility model to solve its technical problem is a servo press for bearings, comprising: a base, on which a PLC controller is installed, symmetrically arranged grooves inside the base, a drive motor installed inside the base, a gear fixedly connected to the output end of the drive motor, the gear being rotatably connected inside the base, racks symmetrically meshing on the gears, limit blocks fixedly connected to the lower surfaces of both sets of racks, the limit blocks being slidably connected inside the grooves, a connecting frame fixedly connected to one side of each set of racks, a fixing plate fixedly connected to the upper surface of the connecting frame, the fixing plate extending to the outside of the base, an anti-slip pad fixedly connected to one side of the fixing plate, and the two sets of fixing plates facing each other, the anti-slip pad increasing the friction with the arc-shaped surface of the bearing, thereby improving the fixing strength of the bearing.

[0007] Preferably, a first connecting rod is fixedly connected inside the two sets of racks, and a rotating rod is rotatably connected to the first connecting rod. The rotating rod is in contact with the inner wall of the base. The first connecting rod drives the rotating rod to move synchronously. The friction between the rotating rod and the inner wall of the base causes it to rotate, thereby improving the smoothness of the rack movement.

[0008] Preferably, the base is symmetrically equipped with slide rails, and a servo motor is mounted on the base. A ball screw is mounted on the output end of the servo motor, and a nut seat is mounted on the ball screw. When the servo motor is started, the ball screw is driven to rotate, thereby adjusting the height of the nut seat and the pressing plate, so as to perform the pressing operation on the bearing.

[0009] Preferably, a limiting frame is symmetrically installed on the arc-shaped surface of the nut seat. The limiting frame is slidably connected inside the slide rail. A second connecting rod is installed at the bottom of the limiting frame. One end of the limiting frame is located inside the slide rail, thereby cooperating with the ball screw to improve the stability of the nut seat movement.

[0010] Preferably, a third connecting rod is installed inside the second connecting rod, and a pressure sensor is installed at the bottom of the limiting frame. The pressure sensor is located inside the second connecting rod. During the pressing process, when the pressure of the third connecting rod on the pressure sensor reaches a certain value, the servo motor is turned off by the PLC controller, and the ball screw rotation is stopped, thereby stopping the pressing operation on the bearing and avoiding damage to the bearing or shaft due to excessive pressing force.

[0011] Preferably, a pressing plate is installed at one end of the third connecting rod, and the PLC controller is connected to the drive motor, servo motor and pressure sensor. The PLC controller controls the drive motor, servo motor and pressure sensor, thereby improving the ease of use of the servo press.

[0012] The advantages of this invention are as follows: starting the drive motor drives the gear to rotate, which in turn drives the two sets of racks to move relative to each other, thereby reducing the distance between the two sets of fixing plates. This allows the two sets of anti-slip pads to come into contact with the surface of the shaft, thus fixing the shaft. This prevents the bearing from shifting or tilting during the pressing process due to lack of fixing during the operation of the servo press. At the same time, it reduces the vibration and shaking of the bearing during the pressing process, improves the stability of the pressing, and avoids the problem of bearing damage during pressing, thereby improving the processing quality of the bearing by the servo press.

[0013] This utility model utilizes a servo motor to drive a ball screw to adjust the height of the nut seat and the limit bracket. Because one end of the limit bracket is located inside the slide rail, it cooperates with the ball screw to improve the stability of bearing press-fitting. At the same time, during the bearing press-fitting process, when the pressure of the third connecting rod on the pressure sensor reaches a certain value, the press-fitting operation of the bearing is stopped to avoid damage to the bearing or shaft due to excessive pressing force, while also improving the machining accuracy of the servo press.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figure 1-5As shown, a servo press for bearings includes: a base 1, a PLC controller 2 mounted on the base 1 (model FX3U), symmetrically arranged grooves 3 inside the base 1, a drive motor 4 installed inside the base 1, a gear 5 fixedly connected to the output end of the drive motor 4, the gear 5 rotatably connected inside the base 1, racks 6 symmetrically meshed on the gears 5, limit blocks 7 fixedly connected to the lower surfaces of both racks 6, the limit blocks 7 slidably connected inside the grooves 3, a connecting frame 8 fixedly connected to one side of each rack 6, a fixing plate 9 fixedly connected to the upper surface of the connecting frame 8, the fixing plate 9 extending to the outside of the base 1, an anti-slip pad 10 fixedly connected to one side of the fixing plate 9, and the two fixing plates 9 facing each other, a first connecting rod 11 fixedly connected inside the two racks 6, a rotating rod 12 rotatably connected to the first connecting rod 11, and the rotating rod 12 adhering to the inner wall of the base 1;

[0023] A press is used during the pressing and mounting of bearings. The pressing effect directly affects the performance and lifespan of vehicles or equipment. To avoid damage to the bearing due to misalignment or tilting during pressing caused by insufficient bearing fixation, a servo press for bearings is proposed. In actual use, the shaft to be processed is placed on the base 1, with the shaft positioned between two sets of fixing plates 9. The PLC controller 2 controls the operation of the drive motor 4, starting the drive motor 4 to rotate the gear 5. Since both sets of racks 6 mesh with the gear 5, the rotation of the gear 5 drives the two sets of racks 6 to move relative to each other, thereby reducing the distance between the two sets of fixing plates 9 and the anti-slip pads 10, ensuring that the two sets of anti-slip pads 10 are in contact with the surface of the shaft. The shaft is fixed by the fixing plate 9, and then the drive motor 4 is turned off. This fixes the position of the shaft to be processed, thus avoiding the bearing from shifting or tilting during the press-fitting process due to the lack of bearing fixation. It also reduces the vibration and shaking of the bearing during the press-fitting process, improves the stability of the press-fitting process, and avoids the problem of bearing damage during the press-fitting process. This improves the processing quality of the bearing by the servo press. When the rack 6 moves, it drives the rotating rod 12 to move synchronously through the first connecting rod 11. The friction between the rotating rod 12 and the inner wall of the base 1 causes it to rotate, thereby improving the smoothness of the rack 6's movement. In cooperation with the gear 5, it can avoid the component from getting stuck during the bearing fixation process, thereby improving the fixing efficiency of the bearing.

[0024] Please see Figure 1-5As shown, slide rails 13 are symmetrically mounted on the base 1, servo motors 14 are mounted on the base 1, ball screws 15 are mounted on the output end of servo motors 14, nut seats 16 are mounted on ball screws 15, limit frames 17 are symmetrically mounted on the arc-shaped surface of nut seats 16, limit frames 17 are slidably connected to the inside of slide rails 13, a second connecting rod 18 is mounted at the bottom of limit frames 17, a third connecting rod 19 is mounted inside the second connecting rod 18, a pressure sensor 20 is mounted at the bottom of limit frames 17, the pressure sensor 20 is located inside the second connecting rod 18, a pressing plate 21 is mounted at one end of the third connecting rod 19, and PLC controller 2 is connected to drive motor 4, servo motor 14 and pressure sensor 20;

[0025] After fixing the bearing to be press-fitted using two sets of fixing plates 9, the servo motor 14 is started, driving the ball screw 15 to rotate, thereby adjusting the height of the nut seat 16 and driving the limit brackets 17 on both sides to move synchronously. Since one end of the limit bracket 17 is located inside the slide rail 13, it cooperates with the ball screw 15 to improve the stability of the movement of the nut seat 16. The pressing plate 21 is driven to move synchronously through the second connecting rod 18 and the third connecting rod 19, so that the pressing plate 21 can perform the pressing operation on the bearing. During the pressing process, the third connecting rod 19 moves into the second connecting rod 18. When the pressure of the third connecting rod 19 on the pressure sensor 20 reaches a certain value, the servo motor 14 is turned off by the PLC controller 2, stopping the rotation of the ball screw 15, thereby stopping the pressing operation on the bearing and avoiding damage to the bearing or shaft due to excessive pressing force. At the same time, it improves the processing accuracy of the servo press.

[0026] Working principle: The shaft to be processed is placed on the base 1, with the shaft positioned between two sets of fixing plates 9. The PLC controller 2 controls the operation of the drive motor 4, starting the drive motor 4 to rotate the gear 5. Since both sets of racks 6 mesh with the gear 5, the rotation of the gear 5 drives the two sets of racks 6 to move relative to each other, thereby reducing the distance between the two sets of fixing plates 9 and the anti-slip pads 10. This allows the two sets of anti-slip pads 10 to contact the surface of the shaft, thus fixing the shaft with the fixing plates 9. The servo motor 14 is then started, driving the ball screw 15 to rotate, thereby adjusting the height of the nut seat 16 and the limit brackets 17 on both sides. This adjustment is achieved through the second connecting rod 18 and the third connecting rod 19. The connecting rod 19 drives the pressing plate 21 to move synchronously, so that the pressing plate 21 can perform the pressing operation on the bearing. During the pressing process, when the pressure sensor 20 is pressed by the third connecting rod 19 to a certain value, the servo motor 14 is turned off by the PLC controller 2, and the rotation of the ball screw 15 is stopped, thereby stopping the pressing operation on the bearing and avoiding damage to the bearing or shaft due to excessive pressing force. Then, the servo motor 14 drives the ball screw 15 to rotate in the opposite direction, so that the pressing plate 21 moves upward. At the same time, the drive motor 4 drives the gear 5 to rotate in the opposite direction, which can increase the distance between the two sets of fixing plates 9, thereby releasing the fixing of the bearing and allowing the processed bearing to be taken out.
