Technical Field

[0001] This utility model relates to the field of bearing ring technology, specifically to an automatic centering bearing ring turning device. Background Technology

[0002] Bearing rings are ring-shaped parts of radial rolling bearings with one or more raceways. Bearing rings need to be machined by turning to make them conform to the manufacturing process.

[0003] However, bearing ring turning devices often use rigid contact when clamping the workpiece, which can easily damage the workpiece surface. They also cannot adapt to small deviations in the inner and outer diameters of the rings, making the machining process inconvenient and no longer meeting the user's needs. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic centering bearing ring turning device to solve the problems mentioned in the background art, where bearing ring turning devices often make hard contact when clamping the workpiece, which easily damages the surface of the workpiece and cannot adapt to the slight deviation of the inner and outer diameters of the ring, making the processing inconvenient and no longer meeting the user's needs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic centering bearing ring turning device, comprising a machine body, the machine body having an internal cavity, an automatic centering machine fixedly mounted at the bottom of the machine body, a turning machine fixedly mounted at the top of the automatic centering machine, a machining table fixedly mounted on one side of the machine body, a chuck fixedly mounted on one side of the machining table, the chuck having an internal cavity, three connecting frames fixedly mounted inside the chuck, return boxes fixedly mounted on both sides, guide grooves formed on the front and rear surfaces of the connecting frames, a clamping block mounted at the end of the connecting frame away from the chuck, a water-filled buffer bag fitted on the outer surface of the clamping block, conduits connected to the opposite sides of the two return boxes, guide blocks fixedly mounted on the front and rear surfaces of the clamping block, and a hydraulic cylinder fixedly mounted inside the guide groove.

[0019] The utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. The following embodiments are only descriptive and are not limiting of the scope of protection of this utility model.

[0020] Please see Figure 1-4This utility model provides a technical solution: an automatic centering bearing ring turning device, including a body 1, which is used to set corresponding components. The body 1 has an internal cavity. An automatic centering machine 2 is fixedly installed at the bottom of the body 1. A lifting cylinder is installed inside the automatic centering machine 2, and the output end of the lifting cylinder is fixedly connected to a turning machine 3. Centering induction probes are fixedly installed on the front surfaces of both the turning machine 3 and the machining table 4. When the two centering induction probes are misaligned, the automatic centering machine 2 will automatically start to raise and lower the turning machine 3 for centering. The turning machine 3 is fixedly installed on the top of the automatic centering machine 2 and is used to process the product. A machining table 4 is fixedly installed on one side of the body 1, and a chuck 5 is used to set up the chuck. A clamping assembly is also fixedly installed on one side of the machining table 4. The chuck 5 has an internal cavity. Three connecting frames 6 are fixedly installed inside the chuck 5. The connecting frames 6 are used to set the corresponding components. Return boxes 7 are fixedly installed on both sides of the connecting frames 6. The return boxes 7 are used to temporarily store water flow. Guide grooves 8 are opened on the front and rear surfaces of the connecting frames 6. The guide grooves 8 facilitate the movement of the guide blocks 12. A clamping block 9 is set at the end of the connecting frame 6 away from the chuck 5. The clamping block 9 plays a clamping role. A water bladder buffer bag 10 is sleeved on the outer surface of the clamping block 9. The water bladder buffer bag 10 plays a buffering role. The opposite sides of the two return boxes 7 are connected to the conduit 11. The conduit 11 plays a guiding role. Guide blocks 12 are fixedly installed on the front and rear surfaces of the clamping block 9. The guide blocks 12 are used for guiding. A hydraulic cylinder 13 is fixedly installed inside the guide groove 8. The hydraulic cylinder 13 adopts a common model that conforms to the present application document.

[0021] Furthermore, a safety door 14 is movably provided on the front surface of the body 1, and a handle is fixedly provided on the front surface of the safety door 14, wherein the handle facilitates the user to open the safety door 14.

[0022] Furthermore, the connecting frame 6 adopts an isosceles triangle arrangement design, which makes the device more stable when clamped.

[0023] Furthermore, the water-filled buffer pack 10 is fixedly connected to the clamping block 9, and the water-filled buffer pack 10 is connected to the conduit 11. The water-filled buffer pack 10 can play a buffering role.

[0024] Furthermore, the opposite sides of the two guide blocks 12 extend into the interior of the guide groove 8 and contact the inner wall of the guide groove 8. The guide blocks 12 and the guide groove 8 are movably connected. This design can guide the clamping block 9.

[0025] Furthermore, the output end of the hydraulic cylinder 13 located at the bottom is fixedly connected to the guide block 12, wherein the hydraulic cylinder 13 can drive the guide block 12 to move.

[0026] Furthermore, a base is fixedly installed at the bottom of the body 1, which can support the body 1.

[0027] Working principle: When using this device, when the user places the ferrule into the chuck 5 for clamping, the user activates the hydraulic cylinder 13 to push the guide block 12 to drive the clamping block 9 to clamp the ferrule. During clamping, the water-filled buffer bag 10 will first contact the ferrule, and the pressure generated will act on the water-filled buffer bag 10. The water-filled buffer bag 10 contains water, which, after being squeezed by the pressure, will flow through the conduit 11 to the return box 7. In this process, the pressure will be relieved, avoiding damage to the ferrule. After a portion of the water-filled buffer bag 10 flows out, a portion will remain, which will form a support in the water-filled buffer bag 10, making the water-filled buffer bag 10 fit more closely to the workpiece and enabling it to adapt to the workpiece.

[0028] Based on the above work process, we can conclude that:

[0029] This automatic centering bearing ring turning device, through the setting of a return box 7, a water bladder buffer 10, a conduit 11, and a hydraulic cylinder 13, adopts a flexible clamping design during use, which can effectively avoid damage to the product surface. Moreover, during clamping, the flexible design can shrink and adapt to the size of the product, fully fitting the product and ensuring processing accuracy. This brings convenience to the user, improves the practicality of the device, and meets the user's needs.
