[0020] 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.

[0021] Please see Figure 1-4This utility model provides a technical solution: a positioning device for processing bearing rings, including a base 1. The base 1 is used to set corresponding components. Connecting grooves 2 are provided on both sides of the front surface of the base 1. The connecting grooves 2 are used to set hydraulic cylinders 3. Hydraulic cylinders 3 are fixedly installed on opposite sides of the two connecting grooves 2. The hydraulic cylinders 3 are used to connect to positioning blocks 4. Positioning blocks 4 are fixedly installed on the output ends of the two hydraulic cylinders 3 on opposite sides. The positioning blocks 4 can position the product. A damping pad 5 is fixedly installed on the rear surface of the base 1. The damping pad 5 is used to set corresponding components. The interior of the damping pad 5 has a hollow section. A cross-shaped partition 7 is fixedly installed in the middle of the damping pad 5. The cross-shaped partition 7 is used to install corresponding components. The damping pad 5 is internally arranged with an array of aluminum foam honeycomb panels 8. The aluminum foam honeycomb panels 8 can absorb vibration, and the honeycomb holes in the aluminum foam honeycomb panels 8 can naturally form a damping cavity, thereby absorbing high-frequency vibration noise and achieving noise reduction. A through groove 9 is opened on the front surface of the cross-shaped partition 7. The through groove 9 is used to install corresponding components. A counterweight ball 10 is installed inside the through groove 9. The counterweight ball 10 is used for movement. An energy-absorbing sponge block 11 is arranged around the inner wall of the through groove 9. The energy-absorbing sponge block 11 can absorb energy.

[0022] Furthermore, the front end of the positioning block 4 extends to the outside of the connecting groove 2, wherein the positioning block 4 is capable of positioning the product.

[0023] Furthermore, mounting grooves 12 are provided at the four corners of the front surface of the damping pad 5, which facilitate the user's installation of the device.

[0024] Furthermore, the aluminum foam honeycomb panel 8 is fixedly connected to the cross partition 7. The aluminum foam honeycomb panel 8 can absorb vibration, and the honeycomb holes in the aluminum foam honeycomb panel 8 can naturally form a damping cavity, thereby absorbing high-frequency vibration noise and achieving noise reduction.

[0025] Furthermore, there are several through slots 9, and the through slots 9 and the cross-shaped partition 7 are integrated into one design. The through slots 9 are used to set the corresponding components.

[0026] Furthermore, the number of energy-absorbing sponge blocks 11 is several, and each pair of energy-absorbing sponge blocks 11 is designed to be equidistant from each other, wherein the energy-absorbing sponge blocks 11 are capable of absorbing energy.

[0027] Furthermore, a support spring 6 is fixedly provided on the rear surface of the counterweight ball 10, and the rear end of the support spring 6 is fixedly connected to the rear surface in the through groove 9. The support spring 6 can support the counterweight ball 10.

[0028] Working principle: When using this device, the user places the bearing ring to be processed at the two positioning blocks 4. Then, the user starts the hydraulic cylinder 3 to pull the positioning blocks 4 to move, so that the positioning blocks 4 exert force to position and clamp the bearing ring. When vibration occurs during product processing, the damping pads 5 can absorb the vibration transmitted from the base 1. The foamed aluminum honeycomb plate 8 absorbs the vibration again, and the honeycomb holes in the foamed aluminum honeycomb plate 8 can naturally form a damping cavity, thereby absorbing high-frequency vibration noise and achieving noise reduction. The counterweight ball 10, when subjected to vibration, shakes irregularly under the influence of the vibration, thereby contacting the energy-absorbing sponge block 11 and transmitting the vibration to the energy-absorbing sponge block 11 for absorption, thus absorbing the vibration again.

[0029] Based on the above work process, we can conclude that:

[0030] This positioning device for bearing ring machining, by incorporating a damping pad 5, a foamed aluminum honeycomb plate 8, a counterweight ball 10, and an energy-absorbing sponge block 11, can absorb the vibration generated during product cutting, thereby preventing chatter marks on the product surface, improving product processing quality, providing convenience for users, enhancing the practicality of the device, and meeting user needs.
