Description

Technical Field

[0001] The utility model relates to the field of crystal processing equipment, in particular to a loose bushing mechanism for a crystal grinding and polishing machine. Background Art

[0002] When the crystal grinding and polishing machine is processing, the crystal blank is transferred by controlling the opening and closing of the bushing. Specifically, the opening and closing of the bushing is controlled by the rotation of a support sleeve shaft. The surface of the support sleeve shaft is provided with support sleeve teeth. During the rotation of the support sleeve teeth, the sleeve shell on the bushing is driven to move upward. The positioning claws in the bushing can expand outward after being freed from the restraint. At this time, the crystal blank can be sent into the positioning claws, and then the limit on the sleeve shell can be released to achieve the positioning of the crystal blank. In this structure, the contact area between the support sleeve teeth and the sleeve shell is relatively small. In the actual production process, the contact points on the surface of the sleeve shell are prone to wear. Once damaged, the entire bushing needs to be replaced, resulting in excessively high operation and maintenance costs of the equipment. Utility Model Content

The structure of the bushings 22 is the same as that of the prior art, and both include a sleeve and a positioning claw piece. Linkage blocks 23 are fixed on both sides of the aluminum rack 2, and the linkage blocks 23 are rotatably connected to the support 1, and the linkage blocks 23 are fixedly connected to the second driving cylinder 12; a loose sleeve plate 3 that can be lifted and lowered relative to the support 1, the loose sleeve plate 3 is located below the support 1, the loose sleeve plate 3 is fixedly connected to the first driving cylinder 11, and a plurality of clamping notches 31 are provided on one side of the loose sleeve plate 3.

[0024] When the mechanism is in operation, the second driving cylinder 12 pushes the linkage block 23 to rotate, and the linkage block 23 drives the aluminum rack 2 and the aluminum row 21 to rotate synchronously. After the bushing 22 enters the clamping notch 31, the linkage block 23 stops rotating, and then the first driving cylinder 11 drives the loose sleeve plate 3 to rise, and after the clamping notch 31 abuts against the sleeve shell on the bushing 22, the sleeve shell is driven to rise by the loose sleeve plate 3, and the bushing 22 can be controlled to open for loading. In the mechanism, the contact area between the loose sleeve plate 3 and the sleeve shell is significantly increased compared with the bracing teeth in the prior art, and the force per unit area on the bushing 22 is reduced, thereby reducing the probability of damage to the bushing 22 during the production process.

The intersection of the first linkage arm 231 and the second linkage arm 232 is a rotating connection part 233. The rotating connection part 233 is rotatably connected to the connection seat 13. The first linkage arm 231 is arc-shaped. The arc-shaped first linkage arm 231 can reduce the interference with other components during the actual production process, ensuring the normal operation of the entire equipment. Specifically, the end of the first linkage arm 231 is hinged to the second driving cylinder 12, and the second linkage arm 232 is fixedly connected to the aluminum rack 2.

The rotating connecting part 233 can be provided with a through hole, and a rotating shaft is provided in the rotating groove 131. By inserting the rotating shaft into the through hole, the rotating connection effect of the rotating connecting part 233 and the rotating groove 131 can be achieved.

[0029] As shown in the figure, the cross-section of the snap-fitting notch 31 is semicircular, and the sleeve shell of the bushing 22 is cylindrical. The semicircular snap-fitting notch 31 can increase the contact area with the sleeve shell as much as possible, thereby reducing the probability of damage to the sleeve shell during use and extending the service life of the equipment.
