Description

Technical Field

[0001] The invention belongs to the field of deep groove ball bearing processing, and in particular relates to a deep groove ball bearing inner ring outer groove processing device. Background Art

[0002] Deep groove ball bearings are one of the most widely used types of rolling bearings. The quality of the precision grooves (raceways) on the outer surface of their inner rings directly determines the bearing's load capacity, rotational accuracy, and service life. Machining the outer grooves of the inner rings is a critical process in bearing manufacturing and typically requires high-precision, specialized grinding machines or turning equipment.

[0003] Currently, equipment used for this type of machining primarily employs two modes for loading and unloading workpieces (bearing inner rings): manual loading and unloading, and automated loading and unloading by a robot (or manipulator). Manual loading and unloading relies on a human operator to manually place the inner ring blank onto the machine tool fixture and manually remove the finished product after machining. Automated loading and unloading by a robot uses a pre-programmed robotic arm, coupled with an appropriate end effector and sensors, to automatically grasp, position, load, and unload the workpiece after machining.

[0004] However, both of the above-mentioned existing technical solutions have obvious limitations. Although the equipment investment cost of manual loading and unloading is relatively low, it has disadvantages such as low automation, production efficiency is limited by the worker's operating speed, unstable rhythm due to fatigue, safety hazards, and difficulty in meeting the needs of continuous large-scale production. On the other hand, although the use of robots for automatic loading and unloading can significantly improve production efficiency and automation level, ensure the stability of processing rhythm, and improve operation safety, its system structure is complex (requiring a robot body, control system, end tooling, possible safety fences and sensors, etc.), resulting in high overall equipment costs and huge one-time investment costs, which are often unaffordable for small and medium-sized bearing manufacturers. At the same time, its programming and debugging are relatively complex, and it may not be flexible enough to adjust the model for different specifications of products. Therefore, it is difficult for existing technologies to achieve an ideal balance between high efficiency and low cost, which restricts the further optimization and upgrading of the deep groove ball bearing inner ring manufacturing process. It is urgent to develop a loading and unloading solution that combines high automation efficiency and economy. Summary of the Invention

An upwardly inclined feed shell 105 is fixedly provided on the side wall of the material rack 104, and the feed shell 105 is connected to the material rack 104. A lifting rack 106 is vertically slidably connected inside the material rack 104, and a telescopic part 107 is fixedly provided at the bottom of the material rack 104. The telescopic part 107 adopts a cylinder or an electric telescopic rod, etc. The telescopic end of the telescopic part 107 is connected to the bottom of the material rack 104, and a semi-arc cleaning brush 112 is fixedly provided on the side of the lifting rack 106 away from the concave movable plate 102.

[0037] In the embodiment of the present invention, when in use, the inner ring of the deep groove ball bearing to be processed is put into the feed shell 105. A plurality of deep groove ball bearing inner rings can be stored in the feed shell 105. The inner ring of the deep groove ball bearing at the lower end of the feed shell 105 slides into the feed rack 104 and is located on the ejector rack 106. The telescopic member 107 is extended, and the telescopic member 107 drives the ejector rack 106 to move upward. The ejector rack 106 drives the inner ring of the deep groove ball bearing to move above the workbench 101. The side wall of the ejector rack 106 blocks the lower end of the feed shell 105 to prevent the inner ring of the deep groove ball bearing in the feed shell 105 from continuing to enter the feed rack 104. The rotating component 6 drives the main shaft 111 to rotate, and the moving component 2 5 drives the main shaft 111 to move. One end of the main shaft 111 extends into the ejector rack When the spindle 111 is moved to the side wall of the rack 106, the semi-arc cleaning brush 112 wipes the rotating spindle 111, thereby preventing residual processing debris on the spindle 111 and affecting the clamping accuracy of the fixing component 7 on the spindle 111 on the inner ring of the deep groove ball bearing. When one end of the spindle 111 moves to the ejecting rack 106 and inserts into the inner ring of the deep groove ball bearing, the spindle 111 stops rotating, and the fixing component 7 fixes the inner ring of the deep groove ball bearing on the spindle 111, and the telescopic member 107 contracts.

[0038] The moving component 2 5 continues to drive the main shaft 111 to move into the concave moving plate 102, the rotating component 6 drives the main shaft 111 to rotate, the main shaft 111 drives the inner ring of the deep groove ball bearing to rotate, the moving component 1 2 drives the concave moving plate 102 to move, the concave moving plate 102 drives the tool 103 to contact the processing position of the inner ring of the deep groove ball bearing, and the outer groove of the inner ring of the deep groove ball bearing is processed by the rotation of the inner ring of the deep groove ball bearing and the feeding of the tool 103 by the concave moving plate 102. After the outer groove depth meets the standard, the moving component 1 2 drives the concave moving plate 102 to move in the opposite direction, and the concave moving plate 102 drives the grinding and polishing mechanism 3 to contact the outer groove of the inner ring of the deep groove ball bearing, and then polishes the outer groove of the inner ring of the deep groove ball bearing, thereby improving the processing quality of the outer groove of the inner ring of the deep groove ball bearing;

[0039] After the grinding and polishing is completed, the moving component 1 2 drives the concave moving plate 102 to move, thereby moving the tool 103 and the grinding and polishing mechanism 3 away from the processed deep groove ball bearing inner ring, the main shaft 111 stops rotating, and the moving component 2 5 drives the main shaft 111 to move in the opposite direction. The main shaft 111 drives the processed deep groove ball bearing inner ring from the avoidance hole 109 into the material withdrawal guide housing 108. The fixing component 7 releases the processed deep groove ball bearing inner ring, and the main shaft 111 continues to move in the opposite direction. The main shaft 111 is pulled out of the material withdrawal guide housing 108 from the material withdrawal hole 110. The processed inner ring of the deep groove ball bearing is retained in the material stripping guide housing 108 and is stripped by the guide of the material stripping guide housing 108, thereby completing the processing of the inner ring of the deep groove ball bearing once. Repeat the above operation to proceed to the processing of the next inner ring of the deep groove ball bearing. The present invention can complete the loading and unloading of deep groove ball bearings, the cutting and grinding of deep groove ball bearings, and the cleaning of the main shaft 111 by moving and rotating the main shaft 111, making the processing of deep groove ball bearings more continuous, improving processing efficiency and processing accuracy, and reducing manual participation.
