[0002] Bearings are an important component in contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. When installing ball bearings, most of the bearings currently rely on manual participation to assemble the bearings to the rotating shaft.

[0033] Reference Figure 1-Figure 12The present invention proposes a bearing assembly robot, including a robot body 1, at least two rotating frames 2 are rotatably installed on the outer periphery of the robot body 1, the two rotating frames 2 are symmetrically arranged about the robot body 1, and a clamping rod 3 is slidably installed on the rotating frame 2. The rotating frame 2 and the clamping rod 3 can be slidably adjusted and positioned manually, and the sliding position and positioning can also be adjusted by an electric slide rail. The electric slide rail is used for adjustment in the present invention. The rotating frame 2 is a frame-shaped structure, and the electric slide rail is fixedly installed on the clamping rod 3. The sliding of the electric slide rail is fixedly installed on the rotating frame 2, and the clamping rod 3 passes through the rotating frame 2. The clamping rod 3 is an L-shaped rod. The bending sections of the clamping rods 3 are arranged close to each other, and a rotation limit groove 20 is opened on the outer periphery of the robot body 1. The number of the rotation limit grooves 20 is the same as the number of the clamping rods 3 and is arranged one by one. The rotating frame 2 is rotatably installed in the rotation limit groove 20. The clamping rod 3 and the rotating frame 2 rotate in the rotation limit groove 20, which can limit the deviation of the clamping rod 3 and play a protective role at the same time, reducing accidents caused by clamping external objects. The end of the clamping rod 3 away from the robot body 1 (that is, the end of the bending section) is rotatably installed on the clamping block 4, and the spacing between the two clamping blocks 4 can be adjusted, and the two clamping blocks 4 can clamp the shaft. When the two clamping rods 3 are rotated, the two clamping blocks 4 are driven away from each other through the lever principle, thereby clamping the shaft, shaft seat, etc. In actual situations, when assembling the bearing, the shaft is not necessarily in a horizontal state. In addition, the clamping block 4 may not be able to completely clamp the shaft, because before the shaft is installed, some other parts may be installed on the shaft. In order to increase the contact area and increase the friction force during clamping, it is necessary to adjust the angle of the clamping block 4 so that the clamping block 4 can be as close to the surface of the clamping object as possible. The clamping rod 3 is equipped with a directional structure, which can fix the clamping block 4 on the clamping rod 3. Position, when the clamping block 4 is against the side of the clamped object, after the clamping block 4 is rotated to adjust the angle, in order to ensure that there will be no deflection during the bearing assembly process, it is necessary to fix the deflection angle between the column clamping block 4 and the clamping rod 3, thereby ensuring that the position between the robot body 1 and the shaft will not shift. A driving structure is installed on the robot body 1, and the driving structure is used to drive the clamping rod 3 to rotate on the robot body 1; when driving the clamping block 4 to clamp the shaft, the driving structure simultaneously drives the two clamping rods 3 and the rotating frame 2 to rotate synchronously, and the clamping blocks 4 at the ends of the bending sections of the two clamping rods 3 move close to each other and clamp the shaft.

[0034] like Figure 2As shown in, a mounting plate 5 is installed on the robot body 1, and the mounting plate 5 coincides with the axis of the robot body 1, and the spacing between the mounting plate 5 and the clamping positions of the two clamping blocks 4 can be adjusted. An adjusting structure is also installed on the robot body 1, and the adjusting structure is used to adjust the spacing between the mounting plate 5 and the clamping positions of the two clamping blocks 4; four positioning members 6 are installed on the side of the mounting plate 5 close to the clamping block 4; the four positioning members 6 are arranged in a circular array, and the four positioning members 6 can synchronously move towards each other, or synchronously move away from each other, so that the position of the circular axis formed by the four positioning members 6 remains unchanged, and then the four positioning members 6 clamp the bearing or insert the inner ring of the bearing to open and fix the bearing on the side of the mounting plate 5, ensuring that the bearing and the bearing of the mounting plate 5 coincide, and when assembling the bearing, the concentricity of the bearing and the shaft is improved, and the mounting plate 5 is driven to approach the end of the shaft through the adjusting structure, and the bearing is sleeved on the end of the shaft or the bearing is inserted into the shaft hole of the bearing seat.

[0035] like Figure 2 , Figure 8 and Fig. 9 As shown in the figure, a laser lamp 7 is installed at the center position of one side of the mounting plate 5 close to the clamping block 4. The laser lamp 7 is retracted in the mounting plate 5. When the mounting plate 5 is against the end face of the shaft, it will not squeeze the laser lamp 7. The light emitted by the laser lamp 7 coincides with the axis of the robot body 1. In actual operation, the center position of the end face of the shaft is first determined, and then when the bearing is fixed on the side of the mounting plate 5, the laser lamp 7 is turned on so that the light of the laser lamp 7 is irradiated on the center position of the end face of the shaft. Through the adjustment structure, the directional structure and the driving structure, the clamping block 4 is clamped and fixed on the outer periphery of the shaft, and the concentricity of the robot body 1 and the shaft is fixed at the same time, and then the bearing is installed on the shaft (when the bearing is installed, the mounting plate 5 is against the side of the bearing to ensure that the inner ring and the outer ring of the bearing are pushed in at the same time), thereby completing the assembly operation of the bearing and the shaft, ensuring the concentricity of the bearing installation, and reducing the problems of excessive wear, temperature increase, noise and vibration caused by the offset of the bearing and the shaft assembly. At the same time, the bearing assembly robot can be directly used on the equipment, and the operation is simple and convenient.

[0036] In actual situations, when it is necessary to assemble bearings directly on the shaft on the equipment, many of them are now sleeved on the shaft end, and the staff use tools to hammer the bearings onto the shaft to complete the installation of the shaft, which will cause certain damage to the bearings. If mechanical operation is used, it is necessary to use tools to first fix the position of the shaft, then limit the position of the bearing, and then sleeve the bearing on the shaft. Many devices are used, the operation is relatively cumbersome, and the efficiency is also low (tools are also required for installation after heating or liquid nitrogen cooling of the bearing).

[0037] like Figure 2 and Fig.11As shown in the figure, the adjustment structure includes a hydraulic rod 8; a mounting hole is opened at the end of the robot body 1, the hydraulic rod 8 is fixedly installed in the mounting hole, and the mounting plate 5 is fixedly installed on the output shaft of the hydraulic rod 8. The axis of the hydraulic rod 8 coincides with the axis of the mounting plate 5. The hydraulic rod 8 pushes the mounting plate 5 and the bearing to move, so that the bearing sleeve is mounted on the shaft.

[0038] like Figure 2 , Fig.11 and Fig.12 As shown in the figure, the driving structure includes a lifting rod 9 and a ramp block 10; a through hole is opened on the robot body 1, and the lifting rod 9 is slidably installed in the through hole. The two ends of the lifting rod 9 can respectively abut against the outer periphery of the output shaft of the hydraulic rod 8 and the clamping rod 3; the ramp block 10 is fixedly installed on the outer periphery of the output shaft of the hydraulic rod 8, and the inclination angle of the ramp block 10 is gradually reduced (such as Fig.12The angles between the three straight lines a, b, and c and the horizontal plane gradually decrease), the end of the jacking rod 9 close to the output shaft of the hydraulic rod 8 can slide with the inclined surface on the inclined surface block 10. In actual situations, the power source for driving the clamping rod 3 to rotate is the hydraulic rod 8, and the hydraulic rod 8 drives the bearing to approach the end of the shaft and completes the assembly operation. In the process of driving the bearing to approach the end of the shaft, the clamping rod 3 will be driven to rotate synchronously, so that the clamping block 4 at the end of the clamping rod 3 clamps and fixes the shaft. When the bearing is installed on the end of the shaft, most of the shafts and the inner rings of the bearings are interference fits. It takes a lot of force to put the bearing sleeve on the end of the shaft, so it is necessary to apply a large force to the bearing. It is easy for the two clamping blocks 4 to have insufficient force to clamp the shaft, resulting in sliding friction, which will affect the assembly of the bearing. When the clamping blocks 4 are driven together by the hydraulic rod 8, the inclined angle of the inclined surface on the inclined surface block 10 gradually decreases, and the output shaft of the hydraulic rod 8 drives the two inclined surface blocks 10 to move synchronously (it is necessary to ensure that the light of the laser lamp 7 is irradiated at the center of the shaft end face). The inclined surface with a large inclination angle of the hydraulic rod 8 and the lifting rod 9 slide together, so that the lifting rod 9 The two clamping blocks 4 are driven by the two clamping rods 3 to clamp the shaft. When the bearing is against the end of the shaft, the hydraulic rod 8 needs to continue to work. When the hydraulic rod 8 pushes the mounting plate 5 and the bearing sleeve on the end of the shaft, it will drive the two inclined plane blocks 10 to move at the same time. As the inclination angle of the inclined plane of the inclined plane block 10 gradually decreases, when the output shaft of the hydraulic rod 8 is extended by the same length, the displacement generated by the inclined plane with a large inclination angle driving the lifting rod 9 is greater. The displacement of the lifting rod 9 driven by the inclined plane with a smaller inclination angle is greater than that of the inclined plane, thereby reducing the movement displacement of the clamping block 4. Although the movement displacement of the clamping block 4 is reduced, the two clamping blocks 4 will continue to move closer to each other, making the clamping force greater and increasing the friction (in actual conditions, the clamping block 4, the clamping rod 3 and other parts will produce a certain deformation when subjected to external force, thereby achieving the above-mentioned work), so that the bearing can be installed on the end of the shaft at one time, reducing the possibility that the clamping force of the clamping block 4 is too small to complete the bearing assembly operation.

[0039] A boss is circumferentially connected to the outer periphery of the lifting rod 9, and an anti-slip groove slidably cooperated with the boss is opened in the robot body 1. A return spring 21 is installed in the anti-slip groove, and the two ends of the return spring 21 are respectively against the inner wall of the end of the anti-slip groove and the boss. In actual conditions, the return spring 21 will rebound the boss, driving the boss and the lifting rod 9 to slide and reset.

[0040] like Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7As shown in the figure, the directional structure includes a connector 11, a hydraulic telescopic rod 12 and a transmission assembly; the connector 11 is fixedly connected to the clamping block 4, and the end of the clamping rod 3 is provided with a rotating groove that rotates with the connector 11. A plurality of teeth are circumferentially connected on the outer arc surface of the connector 11, and a hidden hole is provided on the inner wall of the rotating groove. The hydraulic telescopic rod 12 is fixedly installed in the hidden hole, and the end of the output shaft of the hydraulic telescopic rod 12 can mesh with the teeth on the outer arc surface of the connector 11; the transmission assembly is used to convert the linear motion of the jacking rod 9 into the telescopic motion of the output shaft of the hydraulic telescopic rod 12, and the transmission assembly includes a hydraulic chamber 13, a piston block 14, connecting pipe 15 and return spring 16; a placement groove is provided in the clamping rod 3, the hydraulic chamber 13 is fixedly installed in the placement groove, the piston block 14 is slidably installed in the hydraulic chamber 13, and one side of the piston block 14 passes through the hydraulic chamber 13 and the clamping rod 3 and extends to the outside of the clamping rod 3, the end of the lifting rod 9 abuts against the piston block 14, and the connecting pipe 15 connects the hydraulic chamber 13 and the hydraulic telescopic rod 12; the return spring 16 is installed in the hydraulic chamber 13, and the two ends of the return spring 16 are respectively fixedly connected to the inner wall of the hydraulic chamber 13 and one side of the piston block 14. In the specific operation process, the output shaft of the hydraulic rod 8 extends forward The inclined surface of the inclined surface block 10 and the inclined surface of the end of the lifting rod 9 are slidably matched to drive the lifting rod 9 to move in the perforation. The other end of the lifting rod 9 abuts against the piston block 14, which can drive the piston block 14 to retract in the hydraulic chamber 13. The piston block 14 compresses the space in the hydraulic chamber 13, so that the liquid in the hydraulic chamber 13 is squeezed into the connecting pipe 15, and the liquid in the connecting pipe 15 is squeezed into the hydraulic telescopic rod 12. Due to the increase of liquid in the hydraulic telescopic rod 12, the conveying shaft of the hydraulic telescopic rod 12 is driven to extend, so that the end of the hydraulic telescopic rod 12 abuts against the outside of the connector 11. The teeth of the arc surface are meshed, thereby limiting the position of the connector 11 and the clamping block 4, thereby ensuring the deflection angle of the clamping block 4 and the connector 11, and at the same time ensuring the inclination angle between the connector 11 and the robot body 1, thereby ensuring the concentricity of the robot body 1 and the shaft, so as to facilitate the assembly of the bearing. After the assembly is completed, the rebound action of the return spring 16 pushes the piston block 14 out of the clamping rod 3, so that the liquid in the hydraulic telescopic rod 12 returns to the hydraulic chamber 13, thereby driving the output shaft of the hydraulic telescopic rod 12 to disengage from the connector 11, so as to facilitate the adaptive rotation of the clamping block 4 when used next time.

[0041] In actual situations, when the bearing and the bearing seat need to be installed and there is no place to clamp them, the bent section of the clamping rod 3 can be hooked on the bearing seat, and then the clamping rod 3 is used to clamp the bearing seat. A piece of paper is pasted in the mounting hole of the bearing seat, and the center position of the mounting hole is marked on the paper to facilitate laser alignment.

[0042] like Figure 2 , Figure 8 , Fig. 9and Fig.10 As shown in the figure, a plurality of positioning members 6 are arranged in a circular array, and an adjustment mechanism is installed on the mounting disk 5. The adjustment mechanism is used to adjust the position of the positioning member 6 on the mounting disk 5, and the adjustment mechanism includes a driving turntable 17 and a motor 18; a rotating adjustment groove that rotates with the driving turntable 17 is opened in the mounting disk 5, and a spiral groove 19 is opened on the side of the driving turntable 17 close to the positioning member 6, and a thread tooth that slides with the spiral groove 19 is provided at the end of the positioning member 6; the motor 18 is installed in the mounting disk 5, and the output shaft of the motor 18 is fixedly connected to the driving turntable 17. When adjusting the positioning member 6, the driving turntable 17 is driven to rotate by the motor 18. Since the positioning member 6 slides linearly on the mounting disk 5, the thread tooth at the end of the positioning member 6 and the spiral groove 19 on the side of the mounting disk 5 slide and cooperate, which can drive the four positioning members 6 to gather or spread synchronously, and ensure that the axis of the annular structure formed by the four positioning members 6 remains unchanged, thereby ensuring that the axis fixed on the side of the mounting disk 5 coincides with the light emitted by the laser lamp 7, thereby ensuring the accuracy of the installation of the bearing and the shaft.

[0043] Specific working principle: When it is necessary to directly assemble the bearing on the shaft of the equipment, the shaft can be placed stably to ensure that space for installing the bearing is reserved. First, mark the center position of the end face of the shaft, and then fix the bearing to the side of the mounting plate 5 through four positioning pieces 6. Driven by the electric slide rail, the clamping block 4 is placed at the corresponding position of the shaft (in some cases, only a local position on the shaft can be clamped), and the clamping rod 3 is extended to a suitable length (the extension length of the two clamping rods 3 is consistent, and the distance between the bearing and the end face of the shaft is adjusted according to the position of the clamping block 4). The position of the robot body 1 is adjusted so that the light beam emitted by the laser lamp 7 is irradiated on the mark on the end face of the shaft, and then the hydraulic rod 8 is turned on. The hydraulic rod 8 drives the two inclined plane blocks 10 to move synchronously. The inclined plane blocks 10 push the lifting rod 9 to move to both sides, and the lifting rod 9 is pressed against the piston block 14 on the clamping rod 3 (the two lifting rods 9 move synchronously). Due to the friction between the return spring 16 and the inner wall of the piston block 14 and the hydraulic chamber 13 (the clamping block 4 is not pressed against the outer periphery of the shaft), the piston block 14 and the clamping rod 3 are pressed against each other. The two clamping blocks 4 are respectively clamped on the outer periphery of the shaft. At this time, the clamping rod 3 is restricted by the clamping blocks 4 and cannot continue to rotate. The piston block 14 is pushed into the hydraulic chamber 13 by the lifting rod 9. The output shaft of the hydraulic telescopic rod 12 is extended through the hydraulic transmission and meshed with the teeth on the outer arc surface of the connecting head 11, which limits the rotation of the connecting head 11 and limits the inclination angle between the clamping block 4 and the clamping rod 3. Since the lifting rod 9 is against the clamping rod 3, the lifting rod 9 and the robot main The body 1 and the clamping rod 3 form a triangular structure, thereby ensuring the stability of the robot body 1 (at this time, the bearing is close to or has already rested on the end of the shaft), and the hydraulic rod 8 continues to work to push the bearing close to the shaft and put the bearing on the shaft. In this process, due to the continuous push of the lifting rod 9 to rotate the piston block 14 and the clamping rod 3, the clamping block 4 is clamped tighter, reducing the looseness caused by insufficient friction between the clamping block 4 and the shaft, and reducing the impact on the assembly of the bearing. In this process, when the shaft moves a small amount due to external force, the impact on the assembly of the bearing is also very small.

[0044] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
