Description

Technical Field

[0001] The utility model belongs to the technical field of bearing grinding and polishing equipment, and particularly relates to a grinding and polishing equipment for the outer ring of a bearing. Background Technique

[0002] A bearing is a mechanical component used to reduce friction between moving parts of a machine. Its main function is to support the rotating body of the machine, reduce the friction coefficient during its movement, and ensure its rotational accuracy. It consists of three parts: an inner ring of the bearing, an outer ring of the bearing, and rolling elements. The outer ring of the bearing is one of the key components of the bearing. Its main function is to support and fix the overall structure of the bearing. The surface of the outer ring of the bearing is often coated with alumina / titanium oxide. And the surface of the outer ring is required to be smooth. Therefore, after grinding, the outer ring still needs to be polished to reduce the surface roughness of the outer ring of the bearing.

[0003] After the existing outer ring of the bearing is ground by a grinding device, it needs to be disassembled, transferred to other equipment, and repositioned for polishing. Its disadvantages are as follows: First, it reduces the processing efficiency of the outer ring of the bearing; Second, the polishing positioning cannot ensure the consistency with the grinding positioning, which will affect the roundness of the outer ring of the bearing. In addition, when polishing the outer ring of the bearing, the polishing wheel will exert pressure on the bearing. Currently, the polishing equipment does not have a pressure detection function, and it is easy to have problems of excessive or insufficient polishing pressure on the outer ring of the bearing, thus affecting the processing of the outer ring of the bearing.

[0027] From Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 Similarly, the integrated device of the present utility model: the clamping component 3 is located inside the bracket 1, and it includes a clamping sleeve 31, a clamping motor 32, a worm 33, and at least two sets of clamping units. The clamping motor 32, the worm 33, and the clamping units are located inside the sleeve 31; each set of clamping units includes a central rod 30, a worm gear 34, a gear 35, a support rod 36, a rack 37, and a fixed chuck 39; the clamping sleeve 31 is fixedly connected to the output shaft of the driving motor 2, the clamping motor 32 is fixedly connected to the side of the clamping sleeve 31, and the worm 33 is fixed on the output shaft of the clamping motor 32; one end of the support rod 36 is fixedly connected to the side of the clamping sleeve 31, and the other end is sleeved on the middle section of the central rod 30; both ends of the central rod 30 are respectively connected to the worm gear 34 and the gear 35, and the worm gear 34 meshes with the worm 33; the tooth part of the rack 37 extends into the clamping sleeve 31, and the tooth end meshes with the gear 35; a fixed chuck 39 is fixed on one side of the end of the rack 37 outside the clamping sleeve 31.

[0028] The working principle of clamping assembly 3: The output shaft of clamping motor 32 drives worm gear 33 to rotate, causing worm wheel 34 to rotate. This, in turn, drives gear 35 to rotate via central rod 30, causing rack 37 to move in and out. This, in turn, causes the fixed chuck 39 at its end to move in and out, achieving side contact with the inner hole of the bearing outer ring 7 for support and positioning. The in and outward movement of the fixed chuck 39 increases the ease of fixing the bearing outer ring 7.

[0029] The clamping unit is preferably three sets, evenly distributed along the circumference, so as to ensure reliable positioning and clamping of the bearing outer ring 7 by the three evenly distributed fixed chucks 39.

[0030] Example 3

[0031] from Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 The integrated device of this utility model includes a guide plate 38 for each clamping unit. The guide plate 38 is fixedly connected to the side of the clamping sleeve 31, and the non-tooth end of the toothed part of the rack 37 is connected to the side of the guide plate 38.

[0036] When the rack 37 moves inward and outward, it drives the movable chuck at its end to move inward and outward. Loosen the screw 313 and adjust the axial position of the chuck sleeve 312 relative to the guide rod 41. When the movable head 314 contacts the outer ring 7 of the bearing, tighten the screw 43.

[0039] Among them, the rotation direction of the output shaft of polishing motor 65 is opposite to the rotation direction of the output shaft of drive motor 2.

[0040] The working principle of the polishing mechanism: The polishing motor 65 drives the polishing wheel 64 to rotate, and at the same time, the hydraulic rod 61 presses the polishing wheel 64 down on the bearing outer ring 7 through the lower pressure wheel frame 62, thereby completing the polishing of the outer circle of the bearing outer ring 7 by 64; the pressure sensor 62 is used to detect the pressure of the polishing wheel 64 on the bearing outer ring 7 during polishing, so as to avoid the problem of excessive polishing pressure causing an increase in the diameter error of the bearing outer ring or insufficient polishing pressure causing insufficient polishing degree of the bearing outer ring, thus ensuring the processing of the bearing outer ring.

[0044] Example 7

[0045] from Figure 1 , Figure 6The present invention relates to an integrated grinding device: the grinding mechanism 5 includes a handwheel 51, a lead screw 52, ​​a guide rod 53, a nut seat 54, a grinding head unit 55, and two support plates 56; the left and right support plates 56 are fixed on the upper part of the lower horizontal plate of the bracket 1; one end of the lead screw 52 is fixedly connected to the support plate near the vertical plate, and the other end passes through the support plate away from the vertical plate and is connected to the handwheel 51; both ends of the guide rod 53 are fixedly connected to the left and right support plates respectively; one hole of the nut seat 54 is connected to the lead screw 52, ​​and the other hole is connected to the guide rod 53; the grinding head unit 55 is mounted on the nut seat 54.

[0046] The working principle of the grinding mechanism 5: The handwheel 51 rotates, driving the lead screw 52 to rotate. The nut seat 54 drives the grinding head unit 55 to move along the guide rod 53 to the underside of the bearing outer ring 7. The grinding wheel in the grinding head unit 55 is rotated by the motor to grind the bearing outer ring 7. The rotation direction of the grinding wheel is the same as the rotation direction of the output shaft of the drive motor 2.

[0047] The working principle of this integrated device is as follows: the outer ring 7 of the bearing is fitted onto the clamping assembly 3 and clamped and fixed by the moving head 314 and the fixed chuck 39. At the same time, three support wheels 42 support the clamping sleeve 31 to improve the stability of the clamping assembly 3. The drive motor 2 drives the outer ring 7 of the bearing to rotate through the clamping assembly 3. The grinding head unit 55 moves to the bottom of the outer ring 7 of the bearing, and the motor drives the grinding wheel to grind the outer circle of the outer ring 7 of the bearing. After the grinding head unit 55 moves away, the polishing wheel 64 descends and contacts the outer ring 7 of the bearing. The polishing mechanism 65 drives the polishing wheel 64 to polish the outer circle of the outer ring 7 of the bearing, thereby completing and ensuring the processing quality of the outer ring 7 of the bearing.

[0048] The advantages of this integrated device are: 1. Grinding and polishing mechanisms are set up on the same machine, realizing the two processes of grinding and polishing in one machine. It is not necessary to transfer the grinding machine to the polishing machine for polishing after grinding, which greatly improves the processing efficiency. At the same time, the bearing outer ring is positioned by the clamping assembly to complete the two processes of grinding and polishing, so that the positioning of grinding and polishing is consistent and the processing quality of the outer circle of the bearing outer ring is guaranteed. 2. In the polishing process, the pressure sensor is used to detect the pressure of the polishing wheel on the bearing outer ring during polishing. This avoids the problem of excessive polishing pressure causing an increase in the diameter error of the bearing outer ring or insufficient polishing pressure causing insufficient polishing degree of the bearing outer ring, thus ensuring the processing of the bearing outer ring.
