Description

Technical Field

[0001] The utility model relates to a bearing positioning mechanism for a bearing super-light machine. Background Art

[0002] "Ultra-fine" refers to an ultra-fine polishing process, which is used to achieve an extremely high surface finish. This type of process is often used on parts that require high precision and high finish, such as optical components, precision bearings, etc., and can be understood as an advanced polishing technology.

[0003] The ultra-bright process is used for the groove surface machining of bearings to ensure that these surfaces achieve the required smoothness and accuracy, thereby ensuring the performance and life of the bearings. Therefore, accurate workpiece positioning is particularly important, because any slight deviation may affect the quality of the final product.

[0004] However, the turntable or other recycling positioning systems commonly used in the prior art have the following problems. After long-term use, the components of the positioning mechanism (such as clamps, positioning pins or guide rails) may wear. Wear may cause the gap between components to increase, which in turn affects the accuracy of positioning. During the processing, metal chips, grease and other contaminants may accumulate on the positioning mechanism. These contaminants will interfere with the normal movement of the components and cause inaccurate positioning. Under high-speed or high-load operating conditions, mechanical components may change size due to thermal expansion, which will also affect the accuracy of positioning.

[0005] In addition, repeated positioning actions may cause the regression accuracy of the mechanism to decrease, that is, the accuracy of the mechanism returning to the original positioning point decreases over time.

[0006] The above problems are essentially caused by deformation of the positioning mechanism due to various reasons. Utility Model Content

[0007] The purpose of the utility model is to provide a bearing positioning mechanism for a bearing super-optical machine, which can reduce the accuracy impact caused by the deformation of the positioning mechanism.

[0008] The utility model solves the above technical problems through the following technical solutions:

[0009] A bearing positioning mechanism for a bearing super-light machine comprises: a turntable, which is formed in the shape of a circular disk, and has a plurality of U-shaped grooves formed at intervals on the outer circumference of the turntable, wherein the U-shaped grooves are used to accommodate bearings to be polished, a turntable cover plate, which is arranged on the outer side of one end surface of the turntable, and when the turntable rotates, the turntable cover plate blocks the bearing to keep it in the U-shaped groove, and a notch is provided on the turntable cover plate for the bearing to enter and exit, a positioning plate, which is fixed to the other end surface of the turntable and protrudes from the end surface of the turntable, and a V-shaped groove is formed on the outer circumference of the positioning plate, and when the turntable drives the positioning plate to rotate to a predetermined position, a positioning bearing enters the V-shaped groove under the action of an elastic body, and the edges of the positioning bearing respectively contact the two wall surfaces of the V-shaped groove.

[0010] Preferably, there are several V-shaped grooves, which are equal to the number of U-shaped grooves. When one U-shaped groove is aligned with the notch, the locating bearing enters the V-shaped groove, and when the turntable is rotated until the next U-shaped groove is aligned with the notch, the locating bearing also enters the next V-shaped groove.

[0011] Preferably, the opening of the U-shaped groove faces the edge of the turntable and forms a trumpet shape that opens outwards.

[0012] Preferably, the rotating disk and the positioning disk are formed into a co-centric disk shape, and the V-shaped groove is located between two adjacent U-shaped grooves on the rotating disk.

[0013] Preferably, the turntable cover plate is formed with a side wall outside the side of the turntable, and a discharge port is formed on the side wall, and the discharge port is formed in a trumpet shape facing one side of the turntable side.

[0014] Preferably, a chamfer is formed on the opening of the U-shaped groove, which forms an angle of 12 to 40 degrees with the radial direction.

[0015] In summary, the U-shaped groove and the V-shaped groove are used for accommodating and positioning the bearing respectively. This design can reduce the contact surface between the positioning mechanism components, reduce the degree of wear, extend the service life, and improve the accuracy of positioning.

[0020] The present invention will be described more clearly and completely below by way of embodiments in conjunction with the accompanying drawings.

[0021] Figure 1 This is a structural schematic diagram of a bearing positioning mechanism for a bearing super-light machine according to an embodiment of the utility model. Figure 2 It is a schematic structural diagram of a turntable according to one embodiment of the utility model. Figure 3 This is a schematic structural diagram of a turntable cover plate according to an embodiment of the utility model. Figure 4 Schematic diagram of the structure of a positioning plate according to an embodiment of the present utility model. Figures 1 to 4 As shown, the bearing positioning mechanism 100 for a bearing super-light machine involved in this embodiment comprises: a turntable 10, which is formed in a disc shape, and has a plurality of U-shaped grooves 11 formed at intervals on the outer circumference of the turntable 10, the U-shaped grooves 11 being used to accommodate bearings to be polished, a turntable cover plate 20, which is arranged on the outer side of one end surface of the turntable 10, and when the turntable 10 rotates, the turntable cover plate 20 blocks the bearing so that it remains in the U-shaped groove 11, and a notch 21 is provided on the turntable cover plate 20 for the bearing to enter and exit, a positioning plate 30, which is fixed on the other end surface of the turntable 10 and protrudes from the end surface of the turntable 10, and a V-shaped groove 31 is formed on the outer circumference of the positioning plate 30, and when the turntable 10 drives the positioning plate 30 to rotate to a predetermined position, a positioning bearing 32 enters the V-shaped groove 31 under the action of the elastomer, and the edges of the positioning bearing 32 respectively contact the two wall surfaces of the V-shaped groove 31.

[0022] The rotating disk 10 and the positioning disk 30 are designed in the shape of a disk, and the matching U-shaped groove 11 and V-shaped groove 31 are used to accommodate and position the bearings respectively. This design can reduce the contact surface between the positioning mechanism components, reduce the degree of wear, extend the service life, and improve the accuracy of positioning. Compared with the circular groove, the V-shaped groove has only two contact points with the positioning bearing 32, which is not easy to cause positioning deviation.

[0023] Prevent pollution interference: The turntable cover 20 is set on the outer side of one end surface of the turntable 10. When the turntable 10 rotates, the turntable cover 20 can block the bearing, and the gap 21 allows the bearing to enter and exit. This design can prevent pollutants such as metal chips and grease from entering the positioning system, ensuring the normal and stable movement of the positioning mechanism.

[0024] The positioning plate 30 is fixed to the other side end surface of the rotating plate 10 and protrudes from the side end surface. This design can reduce the influence of thermal expansion of mechanical parts caused by high-speed or high-load operating conditions. At the same time, the design of the positioning bearing 32 (609 model) under the action of the elastic body entering the V-shaped groove 31 can also reduce the positioning deviation caused by thermal expansion. Please refer to Figure 1 A spring mechanism is provided near the locating bearing 32 to push the locating bearing 32 into the V-shaped groove 31 .

[0025] The edges of the positioning bearing 32 are in contact with the two wall surfaces of the V-shaped groove 31 respectively. This design can improve the return accuracy and ensure that the accuracy of the mechanism returning to the original positioning point will not decrease over time.

[0026] The rotating disk 10 drives the workpiece (i.e. the bearing to be processed) to perform loading. The rotating disk cover 20 is fixed on the rotating disk 10. After the workpiece is processed, loading and unloading are required. This process is completed by the rotating disk 10 being driven by the lower ruler (not shown in this scheme) to rotate 60°. The positioning bearing 32 and the V-shaped groove 31 on the upper side of the positioning disk 30 are assembled, and the workpiece is processed on the upper side.

[0027] Furthermore, there are several V-shaped grooves 31, which are equal to the number of U-shaped grooves 11. When one U-shaped groove 11 is aligned with the notch 21, the locating bearing 32 enters the V-shaped groove 31, and the turntable 10 is rotated until the next U-shaped groove 11 is aligned with the notch 21, and the locating bearing 32 also enters the next V-shaped groove 31.

[0028] Furthermore, the opening of the U-shaped groove 11 faces the edge of the turntable and forms a trumpet shape that opens outward.

[0029] Furthermore, the rotary disk 10 and the positioning disk 30 are formed into a disk shape with the same center, and the V-shaped groove 31 is located between two adjacent U-shaped grooves 11 on the rotary disk 10.

[0030] Furthermore, the turntable cover 20 is formed with a side wall 23 outside the side of the turntable 10 , and a discharge port 22 is formed on the side wall 23 . The discharge port is formed in a trumpet shape facing one side of the turntable 10 .

[0031] Furthermore, a chamfer 111 is formed on the opening of the U-shaped groove 11, which forms an angle of 12 to 40 degrees with the radial direction.

[0032] The number of V-shaped grooves 31 is equal to the number of U-shaped grooves 11, which ensures that each U-shaped groove has a corresponding V-shaped groove. When a U-shaped groove is aligned with the notch 21, the positioning bearing 32 enters the corresponding V-shaped groove 31. This design ensures that each bearing can be accurately positioned at the correct position, thereby improving the accuracy and stability of positioning.

[0033] The opening of the U-shaped groove 11 is toward the edge of the rotary disk, and forms a trumpet shape that opens outwards. This design can make the bearing enter the groove more easily, while reducing the resistance of the workpiece entering the groove and improving the efficiency of positioning.

[0034] The rotating disk 10 and the positioning disk 30 are formed into a co-centric disk shape, and the V-shaped groove 31 is located between two adjacent U-shaped grooves 11 on the rotating disk 10. This design can ensure the coordinated movement between the positioning disk and the rotating disk and maintain the stable positioning of the bearing.

[0035] The turntable cover 20 is formed with a side wall 23 outside the side of the turntable 10, and a discharge port 22 is formed on the side wall 23, and the discharge port is formed in a trumpet shape facing one side of the turntable 10. This design can effectively prevent contaminants from entering the positioning system, and at the same time facilitate the smooth entry and exit of the bearing, thereby improving the stability and reliability of the positioning system.

[0036] A chamfer 111 with an angle of 12 to 40° with the radial direction is formed on the opening of the U-shaped groove 11. This design can reduce the friction when the bearing enters the groove, allowing the bearing to enter the groove more smoothly, thereby improving the accuracy and efficiency of positioning.

[0037] The above contents are only preferred embodiments of the present invention and cannot limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made within the scope defined in the claims of the present invention should still fall within the protection scope of the present invention.
