Abstract
Description
Technical Field
[0001] This utility model relates to the field of bearing processing and grinding technology, and in particular to a two-end grinding mechanism for bearing manufacturing. Background Technology
[0002] Bearings are components that fix and reduce the coefficient of friction of loads during mechanical transmission. In other words, when other machine parts move relative to each other on a shaft, they are used to reduce the coefficient of friction during power transmission and keep the center position of the shaft fixed. Bearings are a crucial component in modern mechanical equipment. Their main function is to support rotating mechanical bodies and reduce the coefficient of friction of mechanical loads during transmission. According to the different frictional properties of moving elements, bearings can be divided into two categories: rolling bearings and sliding bearings.
[0003] Rolling bearings are generally composed of an outer ring, balls, a cage, and an inner ring. During the machining of the bearing outer ring, the end face of the bearing outer ring needs to be ground to ensure the manufacturability and aesthetics of the outer ring. The traditional grinding method is to manually hold the bearing close to a bench grinder to grind the end face of the bearing. This method is labor-intensive, and the existing bearing outer ring end grinding devices are not very efficient, as they can only grind one side of the end face, which affects production efficiency. Utility Model Content
[0004] This invention provides a two-end grinding mechanism for bearing manufacturing to solve the problems mentioned in the background art.
[0005] To address the aforementioned problems, this utility model provides a two-end grinding mechanism for bearing manufacturing, comprising a grinding disc, a rotating shaft rotatably mounted at the center of the grinding disc, and several positioning pins rotatably mounted at equal intervals around the rotating shaft within the grinding disc. A first grinding plate is installed within the grinding disc, and the rotating shaft and positioning pins pass through the first grinding plate. A drive motor is provided at the bottom of the grinding disc and is connected to the rotating shaft. A gear drive disc is installed at the top of the rotating shaft, and a driven gear disc is rotatably mounted in the positioning pins, meshing with the gear drive disc. Several placement slots are evenly spaced on the driven gear disc. An L-shaped support frame is fixed to the rear side of the grinding disc, and an electric telescopic rod is provided at the top of the support frame. A cover plate matching the grinding disc is installed at the lower end of the electric telescopic rod, and a second grinding plate is installed on the lower surface of the cover plate.
[0006] Preferably, the support frame has a sliding groove, and the rear side of the cover plate has a slider that is slidably connected to the sliding groove.
[0007] Preferably, the bottom surface of the driven gear disk does not come into contact with the first grinding plate.
[0008] The beneficial effects of adopting the above technical solutions are:
[0009] In use, place the outer ring of the bearing at the end that needs to be polished into the placement slot of the driven gear disk. Then, the motor drives the gear drive disk to rotate, thereby driving the meshing driven gear disk to rotate. The rotation of the driven gear disk drives the outer ring of the bearing to move, and in conjunction with the first polishing plate and the second polishing plate, polishes both sides of the outer ring of the bearing, effectively improving polishing efficiency.

Detailed Implementation
[0014] The embodiments of this utility model are described in detail below with reference to the accompanying drawings.
[0015] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, a movable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0017] like Figure 1-2In this embodiment, a bearing manufacturing end-grinding mechanism includes a grinding disc 1. A rotating shaft 11 is rotatably mounted at the center of the grinding disc 1, and a plurality of positioning pins 12 are rotatably mounted equidistantly around the rotating shaft 11 inside the grinding disc 1. A first grinding plate 2 is installed inside the grinding disc 1, and the rotating shaft 11 and positioning pins 12 pass through the first grinding plate 2. A drive motor 13 is provided at the bottom of the grinding disc 1, and the drive motor 13 is connected to the rotating shaft 11. A gear drive disk 3 is installed at the top of the rotating shaft 11. A driven gear disk 4 is rotatably mounted in the positioning pins 12, and the driven gear disk 4 meshes with the gear drive disk 3. A plurality of placement slots 41 are equally spaced on the driven gear disk 4. An L-shaped support frame 5 is fixedly provided on the rear side of the grinding disc 1, and an electric telescopic rod 51 is provided at the top of the support frame 5. A cover plate 6 matching the grinding disc 1 is installed at the lower end of the electric telescopic rod 51, and a second grinding plate 7 is installed in the lower surface of the cover plate 6.
[0018] With the above technical solution, the outer ring of the bearing is placed in the placement groove 41 inside the driven gear disk 4. Then, the cover plate 6 is driven by the electric telescopic rod 51 to press the grinding disk 1, so that the second grinding plate 7 abuts against the upper surface of the outer ring of the bearing. Then, the drive motor 13 drives the rotating shaft 11 to drive the gear drive disk 3 to rotate, thereby driving the driven gear disk 4 to rotate. The driven gear disk 4 drives the outer ring of the bearing in the placement groove 41 to move accordingly. Together with the first grinding plate 2 and the second grinding plate 7, the two ends of the outer ring of the bearing are ground. By grinding both ends simultaneously, the grinding efficiency is improved, and the grinding effect is also improved.
[0019] Preferably, the support frame 5 has a sliding groove 52, and the rear side of the cover plate 6 has a slider 61 that is slidably connected to the sliding groove 52.
[0020] Through the above technical solution, the sliding connection between the slider 61 and the slide groove 52 can ensure the stability of the electric telescopic rod 51 driving the cover plate 6 to move up and down.
[0021] Preferably, the bottom surface of the driven gear disk 4 does not come into contact with the first grinding plate 2.
[0022] With the above technical solution, the bottom of the driven gear disk 4 does not contact the first grinding plate 2, which facilitates the movement of the driven gear disk 4 and thus facilitates the grinding of the bottom end of the bearing outer ring.
[0023] Finally, it should be noted that the above embodiments are only used to illustrate this utility model and are not intended to limit the technical solutions described in this utility model. Therefore, although this specification has described this utility model in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model, and all technical solutions and improvements that do not depart from the spirit and scope of this utility model should be covered within the scope of the claims of this utility model; technologies not described in detail in this utility model are implemented using existing technologies.
