Description

Technical Field

[0001] The utility model belongs to the field of shaft sleeve processing, in particular to a tooling for shaft sleeve processing. Background Art

[0002] The sleeve is a cylindrical mechanical part that is sleeved on the rotating shaft and is a component of the sliding bearing. Generally speaking, the sleeve and the bearing seat adopt an interference fit, and the sleeve and the shaft adopt a clearance fit. When processing the sleeve, the sleeve needs to be fixed, and then the inner and outer walls of the sleeve are processed. However, during the processing of the sleeve, the sleeve needs to be clamped and kept horizontal.

[0003] A Chinese patent with announcement number CN218984526U discloses a tooling for processing shaft sleeves, including a workbench, a circular plate fixedly provided on the upper inner side of the workbench, four clamping blocks slidingly provided in a circular array on the upper end of the circular plate, a first contact surface provided on one side of the upper end of each clamping block, three sliding rods slidingly provided inside each clamping block, an elastic member connected between each sliding rod and the clamping block, a pressure sensor provided at the lower end of each elastic member, a convex portion provided on the upper end of each clamping block deviating from the first contact surface, and each convex portion provided with a second contact surface on the side facing the first contact surface. The staff connects the connectors on the four clamping blocks to the air pump, and the air enters the fourth connecting channel through the one-way valve. The air in the fourth connecting channel moves toward the three air outlets respectively, and the fit between the sleeve and the second contact surface will block the three air outlets on the second contact surface, and the air pressure detector on the lower side of each air outlet is used to detect the air pressure near the air outlet. When the air pressure detected by each air pressure detector is different, the linear drive mechanism is controlled to shrink a certain distance and then continue to extend, so that the four protrusions first loosen the sleeve, and then move radially inward to re-clamp it, and then the air pressure is detected by the air pressure detector. The tooling for sleeve processing in this application needs to detect the air pressure near the air outlet by the air pressure detector, and control the linear drive mechanism to shrink a certain distance for correction, which has low sleeve positioning efficiency and affects the sleeve positioning processing efficiency.

[0004] In view of this, the present utility model is proposed. Utility Model Content
