DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following Figures 1 - 4 is a further detailed description of the present utility model.

[0023] This embodiment discloses a fixture for bearing processing: Refer to Figures 1 - 4, A fixture for bearing processing includes a bracket 10, a clamping assembly 20 and a driving member 30;

[0024] The clamping assembly 20 includes a housing 21, a limiting ring 22, a turntable 23, a plurality of round blocks 24, a plurality of clamping plates 25 and a plurality of chucks 26. The housing 21 is arranged on the bracket 10. A through hole 211 is formed in the housing 21. The limiting ring 22 is fixedly arranged inside the housing 21. The turntable 23 is rotatably arranged inside the housing 21. The round blocks 24 are installed on the turntable 23 by forming a plurality of arc-shaped grooves 231 thereon. The clamping plates 25 are connected to the round blocks 24. The limiting ring 22 slidably installs the clamping plates 25 by forming a plurality of limiting grooves 221 thereon. The clamping ends of the clamping plates 25 pass through the housing 21, extend into the through hole 211, and are connected to the chucks 26;

[0025] The driving member 30 is arranged on the bracket 10 and is used to drive the rotation of the turntable 23.

[0026] When it is necessary to fix the bearing, place the bearing in the through hole 211, start the driving member 30, the turntable 23 rotates, and the clamping plates 25 and the round blocks 24 respectively perform centripetal motion under the constraints of the limiting holes and the arc-shaped grooves 231 until the plurality of chucks 26 abut against the side wall around the bearing, achieving the fixing effect; when facing bearings of different sizes, the clamping area of the chucks 26 can be adjusted by rotating the turntable 23, so as to clamp and fix bearings of different sizes. Therefore, the arrangements of the housing 21, the limiting ring 22, the turntable 23, the plurality of round blocks 24, the plurality of clamping plates 25 and the plurality of chucks 26 enable the staff to fix the bearing by starting the driving member 30, the turntable 23 rotates, and driving the chucks 26 to fix the bearing when facing bearings of different sizes, and the versatility is good.

[0027] Refer to Figures 1 - 2 , A backing plate 212 is arranged on the inner wall of the through hole 211, and support plates 11 are arranged on both sides of the bottom of the bracket 10.

[0028] When it is necessary to fix the bearing, place the bearing on the backing plate 212, start the driving member 30, the turntable 23 rotates, and the clamping plates 25 and the round blocks 24 respectively perform centripetal motion under the constraints of the limiting holes and the arc-shaped grooves 231 until the plurality of chucks 26 abut against the side wall around the bearing, achieving the fixing effect. Therefore, the arrangement of the backing plate 212 facilitates the staff to fix the bearing; and the support plates 11 support the bracket 10.

[0029] Refer to Figure 2, the driving member 30 includes a first gear 31, a second gear 32 and a motor 33. The first gear 31 is fixedly arranged on the turntable 23. The second gear 32 is rotatably arranged at the bottom of the bracket 10. The motor 33 is arranged at the bottom of the bracket 10. The first gear 31 meshes with the second gear 32, and the output end of the motor 33 is connected to the second gear 32.

[0030] When a bearing needs to be fixed, place the bearing in the through hole 211, start the motor 33, the second gear 32 rotates, the first gear 31 rotates, and drives the turntable 23 to rotate. The clamping plate 25 and the round block 24 respectively perform centripetal motion under the constraint of the limiting hole and the arc-shaped groove 231 until multiple chucks 26 abut against the side wall around the bearing, achieving the fixing effect. Therefore, the settings of the first gear 31, the second gear 32 and the motor 33 facilitate the staff to control the rotation of the turntable 23.

[0031] Refer to Figures 2 to 4 , the chuck 26 is arc-shaped, and the four clamping plates 25 are arranged in a circular array around the limiting ring 22.

[0032] The arc-shaped chuck 26 can better fit the side wall of the bearing, increasing the fixing effect; the setting of the distribution positions of the four clamping plates 25 enables the clamping plates 25 to limit the bearing around through the chucks 26, strengthening the limiting effect of the clamping plates 25.

[0033] Refer to Figures 3 to 4 , both sides of the clamping end of the clamping plate 25 are hinged with a connecting rod 27, and one ends of the multiple connecting rods 27 away from the clamping plate 25 are hinged to both ends of the chuck 26; the connecting rods 27 on both sides of the clamping plate 25 form an acute angle with the chuck 26 along the side close to each other.

[0034] When multiple clamping plates 25 perform centripetal motion to clamp the bearing; each chuck 26 will abut against the side wall of the bearing, the chuck 26 is stretched by the force, and the connecting rod 27 flips, so as to achieve the effect of increasing the clamping area of the chuck 26, and the chuck 26 is made of elastic rubber material and is difficult to damage the side wall of the bearing; therefore, the connecting rod 27 and the chuck 26 can further clamp the bearing while being difficult to damage the bearing; thus reducing the probability of loss generated during the fixing process of the bearing.

[0035] The above are all the preferred embodiments of the present invention, and the protection scope of the present invention is not limited accordingly. Therefore: All equivalent changes made according to the structure, shape and principle of the present invention should be covered within the protection scope of the present invention.
