Axial clearance matching machine for hub bearing

Abstract

The invention discloses an axial clearance matching machine for a hub bearing. A preselecting mechanism can be used for measuring an axial clearance of a bearing formed by assembling a to-be-assembled inner ring, a to-be-assembled outer ring and a standard retainer combination together and transmitting information to a control system; a ball storehouse is used for placing to-be-assembled retainer combinations with different tolerance ranges; a nesting mechanism can be used for pressurizing and nesting a preassembled product formed by the to-be-assembled inner ring, the to-be-assembled outer ring and a set of to-be-assembled retainer combination; a carrying mechanism can be used for conveying the pressurized and nested product into a measuring mechanism, carrying the product in the measuring mechanism to a defective product discharging station and carrying the product on the defective product discharging station to a subsequent output station; the measuring mechanism can be used for measuring the axial clearance of the product and transmitting information to the control system; a defective product discharging mechanism can be used for discharging the product on the defective product discharging station; and the control system is used for controlling the action of each mechanism. By using the axial clearance matching machine, the fit rate is increased, the phenomenon that a great number of intermediate products are detained does not appear, and the production efficiency and yield rate are increased.

Description

technical field [0001] The invention relates to a bearing detection and assembly equipment, in particular to a hub bearing axial clearance selection and matching machine. Background technique [0002] During the use of the bearing, if the axial clearance between the inner ring and the outer ring is too large, the axis of the bearing will have significant settlement, which will cause a lot of vibration during use and generate a lot of noise. When the bearing rotates, the precision of the bearing is low and it is easy to Wear and fatigue will greatly affect the bearing capacity. At present, when the bearing is assembled in the factory, the inner and outer rings of the bearing are pre-selected and sorted separately, and after the selection, the assembled product is also measured by another equipment. , resulting in many sizes of sorting rings required, large material warehouse, and low rate of matching. Because they are not together, when the follow-up inspection machine finds ...

[0002] During the use of the bearing, if the axial clearance between the inner ring and the outer ring is too large, the axis of the bearing will have significant settlement, which will cause a lot of vibration during use and generate a lot of noise. When the bearing rotates, the precision of the bearing is low and it is easy to Wear and fatigue will greatly affect the bearing capacity. At present, when the bearing is assembled in the factory, the inner and outer rings of the bearing are pre-selected and sorted separately, and after the selection, the assembled product is also measured by another equipment. , resulting in many sizes of sorting rings required, large material warehouse, and low rate of matching. Because they are not together, when the follow-up inspection machine finds sorting deviations, there will be more intermediate products, resulting in a large number of out-of-tolerance products, and subsequent repairs Large amount of work, high damages
