Description

Technical Field

[0001] This utility model relates to the field of bearing manufacturing technology, and in particular to a grinding wheel locking mechanism for grinding bearing steel balls. Background Technology

[0002] Bearings are important components used in rotating or moving mechanical parts. Their main function is to support rotating mechanical bodies, reduce the coefficient of friction during their movement, and ensure their rotational accuracy. Bearing ball grinding machines are specialized equipment used for precision grinding of bearing balls. Their main function is to improve the surface roughness, roundness, dimensional accuracy, and surface quality of bearing balls through grinding, polishing, and other methods, so that they meet the precision standards required for bearing assembly. They are key finishing equipment in the bearing ball production process. Therefore, a grinding wheel locking mechanism for bearing ball grinding is particularly needed.

[0003] Chinese patent CN216265336U, published on April 12, 2022, discloses a stable horizontal steel ball grinding machine. This machine uses a grinding disc and a balancing disc to grind steel balls. After the steel balls are placed, an adjusting motor is started, which drives an adjusting screw to lower the adjusting plate and adjusting frame. Since the adjusting frame and balancing disc are fixed mechanisms, the balancing disc descends synchronously with the adjusting frame. When the grinding disc is close to the steel ball, the grinding motor is started, causing the grinding disc to rotate and rotate the steel ball along the steel ball guide disc towards the center of the guide disc for grinding. This completes the grinding of the steel ball. However, in actual grinding, the upper and lower grinding discs of this stable horizontal steel ball grinding machine are prone to vibration, causing them to shift and affecting the quality of the finished product.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 This utility model provides a technical solution: a grinding wheel locking mechanism for grinding bearing steel balls, including a table 1, a base frame 2 and pads 3. A sliding frame 4 is connected through one side surface of the table 1. A lead screw 5 is rotatably connected to the side surface of the table 1 near the base frame 2. A connecting frame 6 is threadedly connected to the outer side surface of the lead screw 5. A first motor 7 is fixedly connected to one end of the lead screw 5. A round rod 8 is fixedly connected to one side surface of the connecting frame 6. A connecting piece 9 is fixedly connected to one side surface of the round rod 8. An upper grinding disc 10 is provided on the side surface of the connecting piece 9 near the table 1. A second motor 11 is provided on the upper surface of the connecting piece 9. A lower grinding disc 12 is fixedly connected to one side surface of the table 1. A fixing mechanism 13 is provided on one side surface of the upper grinding disc 10.

[0022] The fixing mechanism 13 includes a fixing member 1301, a rotating member 1302 rotatably connected to one side surface of the fixing member 1301, a support member 1303 fixedly connected to one side surface of the rotating member 1302, a roller 1304 rotatably connected to one side surface of the support member 1303, a ring 1305 slidably connected to the outer surface of the roller 1304, a slot 1306 and a rolling groove 1307 formed on one side surface of the ring 1305. Through the arrangement of the fixing member 1301, the rotating member 1302, the support member 1303, the roller 1304, the ring 1305, the slot 1306, and the rolling groove 1307, in... In use, first rotate the rotating component 1302 so that it rotates inward with the fixed component 1301 as the fulcrum, so that the arc groove on one side surface of the rotating component 1302 is precisely in contact with the outer surface of the upper grinding disc 10 and the lower grinding disc 12. Then, let the roller 1304 at the end of the support component 1303 first pass through the slot 1306 to reach the rolling groove 1307. By utilizing the size matching relationship between the slot 1306 and the roller 1304, the rotating component 1302 is restricted to rotate in the opposite direction, thereby initially locking the upper grinding disc 10 and the lower grinding disc 12. During the grinding operation, the second motor 11 drives the upper grinding disc 10 to rotate, and the rolling groove 1307 on the ring 1305 plays a limiting role for the roller 1304. Since the width of the rolling groove 1307 is adapted to the width of the roller 1304, the roller 1304 is confined within the rolling groove 1307, ensuring that the upper grinding disc 10 and the lower grinding disc 12 are always in close contact, reducing the offset between the upper grinding disc 10 and the lower grinding disc 12, and improving product quality.

[0023] Furthermore, four identical fasteners 1301, rotating parts 1302, supporting parts 1303, and rollers 1304 are provided and are arranged at equal intervals around the vertical central axis of the upper grinding disc 10. The ring 1305, the upper grinding disc 10, and the lower grinding disc 12 are located on the same vertical horizontal line. Through the arrangement of fasteners 1301, rotating parts 1302, supporting parts 1303, and rollers 1304, during use, the equally distributed fasteners 1301, rotating parts 1302, supporting parts 1303, and rollers 1304 can ensure that the grinding disc is subjected to balanced force when rotating at high speed, reducing eccentricity error.

[0024] Furthermore, the rotating component 1302 has an "L"-shaped cross-section. An arc groove is provided on the side surface of the rotating component 1302 near the upper grinding disc 10 and the lower grinding disc 12. Through the setting of the rotating component 1302, during use, the rotating component 1302 can accurately fit with the arc-shaped outer surface of the upper grinding disc 10 and the lower grinding disc 12 through the arc groove design, increasing the contact area between the rotating component 1302 and the grinding disc, improving the clamping force, and avoiding the situation of excessive local force or slippage of the grinding disc during the grinding process.

[0025] Furthermore, the diameter of the roller 1304 is adapted to the slot 1306. The slot 1306 has four of the same size, which are arranged at equal intervals around the vertical central axis of the upper ring 1305. With the slot 1306, when the rotating component 1302 drives the roller 1304 to move to the position of the slot 1306 during use, the roller 1304 can be accurately inserted into the slot 1306 because the diameters of the two are adapted, making the operation smoother.

[0026] Furthermore, the width of the roller 1304 is adapted to the rolling groove 1307, and four feet 3 of the same size are provided. With the setting of the roller 1304 and the rolling groove 1307, when the rotating component 1302 drives the roller 1304 to move in the rolling groove 1307 during use, the roller 1304 will not deviate in the rolling groove 1307 because the widths of the two are adapted. It can always slide smoothly along the trajectory of the rolling groove 1307, ensuring that the rotation trajectory of the rotating component 1302 is precise and controllable, thereby ensuring the stability of the upper grinding disc 10 and the lower grinding disc 12.

[0027] Furthermore, two round rods 8 of the same size are provided and symmetrically distributed along the vertical central axis of the connecting frame 6. Two sliding frames 4 of the same size are provided and symmetrically distributed along the vertical central axis of the table 1. With the round rods 8 provided, when the first motor 7 drives the lead screw 5 to rotate and drive the connecting frame 6 to move linearly, the two symmetrically distributed round rods 8 can provide balanced support and guidance for the connecting frame 6, so that the connecting frame 6 will not tilt or deviate due to unilateral force during movement, and ensure that the upper grinding disc 10 can accurately rise and fall in the vertical direction.

[0028] Furthermore, the cross-section of the sliding frame 4 is designed in a U-shape. The dimensions of the sliding frame 4 and the connecting frame 6 are matched. The lead screw 5 and the round rod 8 are distributed in parallel. With the setting of the sliding frame 4 and the connecting frame 6, the connecting frame 6 can slide smoothly in the sliding frame 4 during use because the dimensions of the two are matched, without producing lateral sway, which greatly improves the stability of the mechanism.

[0029] Working principle: First, the base frame 2 and four feet 3 provide overall support to ensure the stability of the mechanism during grinding. When it is necessary to fix the upper grinding disc 10 and the lower grinding disc 12, the locking action is completed with the help of the fixing mechanism 13. The ring 1305 is in a fixed state. First, rotate the rotating part 1302 so that it rotates inward with the fixing part 1301 as the fulcrum, so that the arc groove on one side of the rotating part 1302 is precisely in contact with the outer surface of the upper grinding disc 10 and the lower grinding disc 12. Then, let the roller 1304 at the end of the support part 1303 first pass through the slot 1306 to reach the rolling groove 1307. By using the size matching relationship between the slot 1306 and the roller 1304, the rotating part 1302 is restricted to rotate in the opposite direction, thereby initially locking the upper grinding disc 10 and the lower grinding disc 12. During the grinding operation, the second motor 11 drives the upper grinding disc 10 to rotate, and the rolling groove 1307 on the ring 1305 plays a limiting role for the roller 1304. Since the width of the rolling groove 1307 is matched with that of the roller 1304, the roller 1304 is confined within the rolling groove 1307, ensuring that the upper grinding disc 10 and the lower grinding disc 12 are always in close contact, avoiding separation of the grinding discs due to centrifugal force or vibration generated by the rotation of the upper grinding disc 10. This completes the use process of a grinding wheel locking mechanism for grinding bearing steel balls.
