[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy.

[0003] Insert bearing units are usually high-precision bearing assemblies composed of sealed insert bearings and various types of insert bearing seats. They have good interchangeability and certain self-aligning functions. They can work in different working conditions and mechanical devices. Insert bearing units are also called bearing units. When they are not equipped with bearings, they are called insert bearing seats.

[0004] Traditionally, the processing of outer spherical bearing seats uses a robot in conjunction with a conveyor belt to transfer the bearing seats to each process processing equipment for processing, forming a set of assembly line processing equipment.

[0029] The hydraulic slip ring 36 includes a rotor ring and a stator ring sleeved outside the rotor ring. The rotor ring is fixedly connected to the output shaft of the drive motor 3 29, and the stator ring is fixedly connected to the inner wall of the groove 9.

After the outer contour of the outer spherical bearing seat is scanned by the laser scanning sensor 26, the processor determines the corresponding type and specification of the outer spherical bearing seat and calls out the information and processing information of the outer spherical bearing seat of the type and specification. The processor establishes a three-dimensional model by scanning the actual overall contour of the outer spherical bearing seat, and compares it with the pre-stored three-dimensional model information to ensure that the degree of fit between the three-dimensional model of the outer spherical bearing seat and the pre-stored three-dimensional model is within the processing requirements; At the same time, the output end of the electric telescopic rod 2 31 corresponding to the 3D sensor 35 is controlled to extend a corresponding length, close to the inner wall of the center hole of the outer spherical bearing seat; the 3D sensor 35 is driven by the driving motor 3 29 to rotate in a circle, ensuring that the center hole of the outer spherical surface is coaxially arranged with the sleeve 30, thereby ensuring the coaxiality of the center hole of the outer spherical bearing seat; If the outer spherical bearing seat does not meet the requirements for fit or coaxiality, it should be replaced to prevent deviations during processing, which would render the processed outer spherical bearing seat unusable.

[0040] After the fixation is completed, the drive motor 8 is started to rotate the substrate 5 90 degrees to one side of the milling assembly 3, and then the output end of the hydraulic telescopic cylinder 5 46 on the fixing assembly 39 is controlled to extend so that the connecting plates 40 are close to each other, and then the output end of the hydraulic telescopic cylinder 4 42 is controlled to extend so that the top block 43 clamps and fixes the substrate 5, thereby improving the stability of the substrate 5 during the processing and improving the processing accuracy.

[0041] Then, the output end of the three-axis linear motor group 2 50 of the milling component 3 is controlled to move, so that the drive motor 51 rotates around the axis of the center hole of the outer spherical bearing seat, and the rotation diameter is smaller than the inner diameter of the center hole, and the milling cutter 54 of the drive motor 51 can mill the inner wall of the center hole, thereby completing the milling work of the outer spherical bearing seat.

[0042] During the milling process, the output end of the second electric telescopic rod 31 is controlled to extend to a corresponding length, and the output end of the third electric telescopic rod 33 corresponding to the second nozzle 34 is controlled to extend to a corresponding length, so that the second nozzle 34 is close to the inner wall of the outer spherical bearing seat, and then the third drive motor 29 is rotated to make the second nozzle 34 follow the milling cutter 54 for cooling and flushing; At the same time, the 3D sensor 35 follows the driving motor 3 29 to perform circular rotation, and the 3D sensor 35 performs size detection and roughness detection on the milling surface of the center hole.

[0043] During the milling process, the 3D sensor 35 is used to detect the size of the milling surface to prevent over-milling or under-milling. At the same time, during the milling process, the 3D sensor 35 is used to detect whether the roughness of the milling surface meets the requirements. If not, it means that the milling cutter 54 is excessively worn and needs to be replaced. The milling component 3 is stopped and reset, and milling is continued after the milling cutter 54 is replaced.

[0044] After the milling is completed, the center hole of the outer spherical bearing seat is scanned twice in a circular rotation by the 3D sensor 35 to determine that the size of the center hole after milling meets the requirements and the coaxiality meets the requirements; When a deviation in the coaxiality of the center hole of the outer spherical bearing seat is detected, it indicates that there is a problem with the clamping assembly 4, and the staff is notified to conduct relevant inspections and adjustments.

[0045] After the milling is completed, the output end of the hydraulic telescopic cylinder 42 is controlled to retract, and the top block 43 does not contact the substrate 5. Then the output end of the hydraulic telescopic cylinder 5 46 is controlled to retract to prevent the substrate 5 from colliding with the fixed component 39 when rotating.

[0046] Control the drive motor 8 to rotate, so that the substrate 5 rotates another 90 degrees along the last rotation direction, so that the side of the substrate 5 without the external spherical bearing seat is horizontally facing upward, and the external spherical bearing seat to be processed is clamped and placed on the support block 10 by the robot. This process is consistent with the operation process of placing the first external spherical bearing seat, and will not be repeated here.

[0047] After the second outer spherical bearing seat is placed, the driving motor 8 is controlled to run again, so that the base plate 5 is rotated 90 degrees again along the last rotation direction, so that the second outer spherical bearing seat faces the side of the milling component 3, and the first outer spherical bearing seat faces the side of the drilling component 2; Then, the output end of the hydraulic telescopic cylinder 5 46 on the fixing assembly 39 is controlled to extend again, so that the connecting plates 40 are brought closer to each other, and then the output end of the hydraulic telescopic cylinder 42 is controlled to extend, so that the top block 43 clamps and fixes the substrate 5, thereby improving the stability of the substrate 5 during the processing and improving the processing accuracy; At the same time, the drilling assembly 2 and the milling assembly 3 are started to machine the first outer spherical bearing seat and the second outer spherical bearing seat respectively; The milling process of the second outer spherical bearing seat is consistent with the operation process of the first milling process, and the specific processing data of the second outer spherical bearing seat is adjusted accordingly according to the relevant model specifications of the outer spherical bearing seat; When drilling the first outer spherical bearing seat, the processor controls the drilling assembly 2 to run the relevant program for processing the outer spherical bearing seat of this model and specification, controls the output end of the three-axis linear motor group 1 48 to move, so that the drill bit 53 on the driving motor 49 is close to the position to be drilled, and starts drilling; During the drilling process, the cylinder 24 is rotated by driving the motor 25 to make the nozzle 27 face the drilling position, and the spray distance and spray angle of the nozzle 27 are adjusted in conjunction with the electric telescopic rod 21. The pump body sprays coolant to the outer spherical bearing seat through the nozzle 27 to cool and flush the drill bit 53.

[0048] After the drilling is completed, the drilling component 2 is controlled to move and reset, and the outer spherical bearing seat is scanned again by the laser scanning sensor 26. The processor re-establishes a three-dimensional model of the scanned contour information of the outer spherical bearing seat and compares it with the corresponding three-dimensional model stored in advance to detect whether the processing information of the drilling meets the requirements. The processing information includes: position, aperture, etc.

[0049] If the processing information of the drilling does not meet the processing requirements, it indicates that there is a problem with the drill bit 53 of the drilling assembly 2. The staff is notified to check and adjust the state of the drill bit 53 of the drilling assembly 2, and the outer spherical bearing seat is recycled.

[0050] The driving motor 8 is controlled to operate again, so that the base plate 5 is rotated 90 degrees again along the last rotation direction, so that the first outer spherical bearing seat is horizontally facing upwards, and the second outer spherical bearing seat is horizontally facing downwards; After the inspection of the first outer spherical bearing seat is completed, the output end of the hydraulic telescopic cylinder three 52 is controlled to extend, and the output end of the hydraulic telescopic cylinder two 19 is controlled to retract, and then it is taken out by the robot, and the qualified outer spherical bearing seat is placed on the next process, and the unqualified outer spherical bearing seat is placed at the recycling area for recycling, and a piece of outer spherical bearing seat to be processed is clamped for clamping, so as to carry out continuous processing.
