Description

Technical Field

[0001] The present invention relates to the technical field of bearing production and processing, and particularly to a multi-functional grinding machine tool for bearing processing. Background Art

[0002] Bearings are important components in mechanical equipment. Their main functions are to support rotating mechanical bodies, reduce the friction coefficient during movement, and ensure rotational accuracy. Bearings can be divided into two major categories: rolling bearings and sliding bearings. Rolling bearings achieve load transmission through the rolling of rolling elements (such as spheres, cylinders, etc.) between the inner and outer rings, while sliding bearings achieve load transmission by forming a lubricating film between the inner and outer rings of the bearing through lubricants; bearings are widely used in various mechanical equipment, such as automobiles, motors, machine tools, wind turbines, metallurgical equipment, etc.

[0003] During the production and processing of bearings, grinding operations need to be performed on the outer and inner rings of the bearings. Most existing grinding machine tools can only process the outer or inner ring of the bearing during the grinding process of the bearing, with relatively single functions and low processing efficiency; in order to process the outer and inner rings of the bearing in one step, the existing method is mostly to connect an inner ring grinding machine tool behind the outer ring grinding machine tool for the bearing. After the outer ring of the bearing is processed, it is sent to the inner ring grinding machine tool through a conveying device for further processing, so as to achieve the grinding of the inner and outer rings of the bearing in one step; however, this connection method has the disadvantages of a large volume of the processing device and a large floor area, and can only be used in large workshops, and is not suitable for small processing workshops.

[0033] In some examples, both the outer ring clamping claws 32 and the inner ring clamping claws 52 of the present invention adopt a three-claw structure.

[0034] The working principle of the present invention is as follows: When grinding the bearing, first, the bearing is conveyed to the loading chute 2 by the automatic conveying device. When the bearing drops to the bottom of the loading chute 2; At this time, the outer ring clamping drive assembly 4 is started. First, the cam roller turntable 41 is started, and it rotates 180 degrees through the cam roller turntable 41, so that the outer ring clamping claws 32 rotate towards the direction of the loading chute 2. Then, the first motor 47 is started to drive the first ball screw 45 to rotate, so that the first sliding seat 42 drives the outer ring clamping module to perform a sliding movement in the X-axis direction, so that the outer ring clamping claws 32 can approach the loading chute 2 until they are inserted into the clamping holes 21, so as to clamp and fix the outer ring of the bearing; At this time, receiving the signal from the sensor, the lifting cylinder 23 drives the limit block 22 to descend, so as to facilitate the outer ring clamping claws 32 to take out the bearing from the bottom of the loading chute 2, and the position of the bearing is rotated and adjusted by the outer ring clamping drive assembly 4; Among them, after the bearing leaves the loading chute 2, the lifting cylinder 23 will push the limit block 22, so that the limit block 22 returns to the bottom position of the loading chute 2, so as to facilitate the automatic conveying device to convey the next bearing to the loading chute 2 for loading; Driven by the outer ring clamping drive assembly 4, the bearing will first perform a sliding movement in the X-axis direction and move closer to the grinding module position, and then rotate 90 degrees through the cam roller turntable 41, so that the bearing can face the inner ring grinding wheel 71; When the bearing is positioned, at this time, the grinding drive assembly is started. The third motor 85 drives the third ball screw 83 to rotate, so as to drive the third sliding seat 8 to drive the grinding module to perform a sliding movement in the Y-axis direction until the inner ring grinding wheel 71 is inserted into the inner ring of the bearing and stops; at this time, the grinding motor 73 is started again, and the grinding motor 73 can drive the first rotating shaft 74 to rotate, so as to drive the inner ring grinding wheel 71 to perform a rotating movement; When the inner grinding wheel 71 rotates, the outer ring clamping drive assembly 4 starts again at this time. By driving the first sliding seat 42 to slide in the X-axis direction, the inner wall of the bearing can be brought closer to and contact the rotating inner grinding wheel 71. Meanwhile, the outer ring drive motor 33 is started to drive the outer ring clamping rotating body 31 to rotate, thereby driving the outer ring clamping claws 32 and the clamped and fixed bearing to rotate synchronously. When the bearing rotates, the inner grinding wheel 71 rotates in the opposite direction in the inner hole of the bearing, so as to realize the grinding process of the inner ring of the bearing; After the inner ring of the bearing is processed, the grinding module resets. The bearing rotates 90 degrees on the cam roller turntable 41 and faces the inner ring clamping claws 52. At this time, the inner ring clamping drive assembly 6 is started to drive the inner ring clamping module to move, so that the inner ring clamping claws 52 approach the bearing until they are inserted into the inner hole of the bearing, so that the inner ring clamping claws 52 can clamp and fix the bearing from the inner ring of the bearing. The outer ring clamping claws 32 release the clamping and, under the drive of the outer ring clamping drive assembly 4, the outer ring clamping claws 32 can move back to the loading chute 2 to clamp and fix the outer ring of the newly loaded bearing, and then repeat the above operation to move to the grinding module to wait for grinding; while the bearing that has just completed the inner ring processing is driven by the inner ring clamping drive assembly 6 to slide in the X-axis direction until the bearing clamped and fixed by the inner ring is in the same vertical plane as the outer grinding wheel 72, waiting for outer ring grinding; After the two bearings are positioned, the grinding module starts again, so that the inner grinding wheel 71 is inserted into the inner hole of the bearing clamped and fixed by the outer ring, and the outer grinding wheel 72 approaches and contacts the outer wall of the bearing clamped and fixed by the inner ring. While the two bearings rotate, the inner grinding wheel 71 and the outer grinding wheel 72 rotate synchronously, so that the inner grinding wheel 71 grinds the inner ring of the bearing clamped and fixed by the outer ring, and the outer grinding wheel 72 grinds the outer ring of the bearing clamped and fixed by the inner ring.

[0035] After the outer ring of the bearing is processed, it can move to the position of the discharge chute 9. At this time, the inner ring clamping claws 52 are released, so that the bearing falls into the discharge chute 9 for discharging. Then, repeat the above steps to clamp and fix the inner ring of the next bearing, and the outer ring clamping claws 32 move to the loading chute 2 to clamp and fix the outer ring of the newly loaded bearing.

[0036] When the grinding machine tool of the present invention processes bearings, it can simultaneously grind the inner or outer rings of two bearings respectively, and the entire processing steps can realize automatic loading, grinding and unloading, making the grinding machine tool of the present invention multifunctional, thereby effectively improving the efficiency of grinding bearings; In addition, for the machine tool of the present invention, by setting the inner grinding wheel 71 and the outer grinding wheel 72 into an integrated modular structure, a compact structure is achieved, thereby effectively reducing the volume of the machine tool, enabling it to be applicable to small workshops and improving the universality of the application scenarios.
