Furthermore, the bearing itself is stationary during processing, and passively receiving processing will affect the uniformity of processing. Therefore, a wear-resistant bearing ring end face grinding device is proposed here. Utility Model Content

[0017] Please refer to the following: Figure 1-4 This utility model discloses a wear-resistant bearing ring end face grinding device, including a processing base 1, a movable base 2 provided in the middle of the top side wall of the processing base 1, and fixed bases 4 provided in the middle of the two side walls of the movable base 2. The fixed bases 4 are detachably connected to the top side wall of the processing base 1 by screws. A drive wheel 9 is connected in the middle of the top side wall of the movable base 2. The movable base 2 and the two fixed bases 4 form a cross-shaped structure. A grinding wheel 8 is provided in the top side wall of each of the two fixed bases 4. The two grinding wheels 8 are rotatably connected to the side walls of the two grinding wheels 8 facing each other and close to the top. A driver is connected in the vertical plate 7 and connected to one end of the grinding wheel 8.

[0018] A limiting wheel 10 is provided on the top and near both ends of the side wall of the movable seat 2. The two ends of the limiting wheel 10 are rotatably connected to the support rods, and the support rods are detachably connected to the top side wall of the movable seat 2 through the bottom end. The drive wheel 9 has the same structure as the limiting wheel 10, and the outer walls of the drive wheel 9 and the limiting wheel 10 are fixedly fitted with anti-slip pads. The edges of the two ends of the limiting wheel 10 and the drive wheel 9 are fixedly connected with anti-detachment retaining rings 13. The drive wheel 9 and the grinding wheel 8 are placed in the middle of the anti-detachment retaining rings 13. A motor 14 is detachably connected to the support rod at one end of the drive wheel 9 by screws.

[0019] The technical effect of this solution is as follows: the bearing sleeve is placed on the limiting wheel 10 and the drive wheel 9. Because anti-disengagement retaining rings 13 are fixed at both ends of the limiting wheel 10 and the drive wheel 9, the bearing sleeve can be limited and ensured to remain stable in its original position. Then, the motor 14 is started to drive the drive wheel 9 to rotate. Because anti-slip pads are fitted on the drive wheel 9 and the limiting wheel 10, the friction between them and the bearing sleeve can effectively drive the bearing sleeve to rotate, achieving its self-rotation effect. This enables active processing and improves the uniformity of processing.

[0020] The top sidewall of the motor 14 is detachably connected to a fixed column 15. The fixed column 15 has a movable groove 18 inside. A tension spring 19 is fixedly connected to the bottom sidewall of the movable groove 18. A pressing column 16 is telescopically inserted into the movable groove 18. One end of the tension spring 19 is fixedly connected to the sidewall of the pressing column 16 located in the movable groove 18. The pressing column 16 has an L-shaped structure. An arc-shaped plate 17 is fixedly connected to the bottom sidewall of the horizontal plate of the pressing column 16. Ball bearings are evenly rotatably connected to the bottom sidewall of the arc plate 17.

[0021] The technical effect of this solution is as follows: To improve the stability of the bearing sleeve, a pressing column 16 is set up. The pressing column 16 is pulled up and the bearing sleeve is placed on one side below the horizontal plate of the pressing column 16. Then, driven by the tension spring 19, the pressing column 16 is pulled down so that the arc plate 17 fits against the inner wall of the bearing sleeve, thereby pressing and positioning the bearing sleeve, thereby improving the stability of the bearing sleeve. The set ball bearings can ensure the normal rotation of the bearing sleeve.

[0022] A groove 5 is provided in the middle of the top side wall of the fixed seat 4. A through hole is provided in the movable seat 2 at the position opposite to the groove 5, and the through hole communicates with the grooves 5 on both sides. A bidirectional screw 11 rotates in the groove 5, and the middle section of the bidirectional screw 11 is inserted into the through hole. A screw driver 12 is detachably connected to the outer wall of one of the fixed seats 4. The output end of the screw driver 12 is detachably connected to one end of the bidirectional screw 11. A slider 6 is threaded on the bidirectional screw 11. The slider 6 is detachably connected to the bottom side wall of the vertical plate 7 through its top end. Two slide rails 3 are detachably connected to the middle of the top side wall of the processing seat 1 by screws. The movable seat 2 is slidably connected to the slide rails 3 through its bottom. The movable seat 2 is attached to one side wall of the fixed seat 4 through its two side walls.

[0023] The technical effect of this solution is as follows: the start screw driver 12 drives the bidirectional screw 11 to rotate, and drives the two grinding wheels 8 to approach the bearing sleeve through the threaded connection. The driver installed in the vertical plate 7 controls the grinding wheels 8 to rotate at high speed, thereby grinding the bearing sleeve. After the processing is completed, the moving seat 2 is controlled to move out along the slide rail 3, and the bearing sleeve can be replaced.

[0024] Specifically, when using this utility model, the pressing column 16 is pulled up, and then the bearing sleeve is placed on the limiting wheel 10 and the drive wheel 9. Then, the moving seat 2 is controlled to move along the slide rail 3 between the two fixed seats 4. Then, the screw driver 12 is started to drive the bidirectional screw 11 to rotate. Through the threaded connection, the slider 6 and the vertical plate 7 are driven to gradually approach the bearing sleeve. At the same time, the motor 14 is started to drive the drive wheel 9 to rotate, thereby driving the bearing sleeve to rotate. When the grinding wheel 8 is in contact with the bearing sleeve, grinding can be performed. With the rotation of the bearing sleeve, the bearing sleeve can be evenly and comprehensively ground. After the processing is completed, the vertical plate 7 is removed first, and then the moving seat 2 is moved out from between the two fixed seats 4. Then, the bearing sleeve is replaced for a new round of processing.

[0025] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0026] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
