Description

Technical Field

[0002] Graphite bushing is a kind of matching part used for sealing and wear protection in mechanical parts. Graphite material has certain self-lubricating and high temperature resistance characteristics, which enables graphite bushing to maintain good performance in some special environments, so that the boring device can expand or process the inner surface of the graphite bushing by turning.

[0003] After searching, the Chinese patent document announcement number is: CN214321900U. This utility model discloses a high-efficiency drilling device for automobile axle sleeve processing, including a main body, a ceiling, an electric telescopic rod and a spindle motor. The clamping mechanism includes a shift rod, a clamping plate, a straight-threaded rod, a gear, a servo motor, a threaded block and a reverse-threaded rod. The servo motor is fixedly connected to one side of the top of the main body. One side of the servo motor is provided with a straight-threaded rod, and the outer side of one side of the straight-threaded rod is provided with a gear. When the utility model controls the servo motor to operate by clicking the control panel, the servo motor drives the straight-threaded rod to rotate through the gear. The two groups of threaded blocks are close to the surface of the straight-threaded rod and the reverse-threaded rod, so that the two groups of threaded blocks drive the clamping plates to be close to each other, and the plate is clamped. At the same time, the shift rod on one side of the shift rod keeps the clamping plate stable. When the plate is processed, the servo motor runs in the reverse direction to make the clamping plate loosen the plate, thereby realizing the clamping function of this device, improving the clamping speed, and improving work efficiency.

At the same time, the shift rod 201 on one side of the shift rod 201 keeps the clamping plate 202 stable to prevent the clamping plate 202 from shifting. When the plate processing is completed, the servo motor 205 runs in the reverse direction to make the clamping plate 202 release the plate to complete the clamping process.
