Automatic measuring device for axial clearance and assembly height of double-row bearings

Abstract

The invention relates to the field of bearing detection, in particular to an automatic measuring device for the axial clearance and the assembly height of double-row bearings. The automatic measuringdevice comprises a fundamental base, a workpiece transport passage, a walking beam assembly, a double jacking assembly and a measuring assembly. The workpiece transport channel, the walking beam assembly and the double jacking assembly are mounted on the fundamental base, a workpiece bearing is driven to move and be positioned on the workpiece transport passage by the walking beam assembly, the double jacking assembly comprises an inner ring jacking mechanism and an outer ring jacking mechanism, the inner ring jacking mechanism is abutted against the lower end of the inner ring of the workpiece bearing during detection, the outer ring jacking mechanism is abutted against the lower end of the outer ring of the workpiece bearing, the measuring assembly is disposed above the double jacking assembly, and the upper end of the workpiece bearing is in contact with the measuring assembly during detection. The automatic measuring device can complete the accurate measurement of the axial clearance and the assembly height parameters in one time, the whole process is automatically controlled, and the on-line culling function is provided for the unqualified workpieces, which is convenient for the worker to perform offline maintenance.

Description

technical field [0001] The invention relates to the field of bearing detection, in particular to an automatic measuring device for axial clearance and assembly height of double-row bearings. Background technique [0002] Bearings are widely used in various industrial fields. For the automotive industry, the two parameters of axial clearance and assembly height of double row bearings are the key factors affecting the quality and service life of bearings. These two parameters must be checked during the production process of bearings. This parameter is strictly controlled, so it needs to be measured accurately, otherwise it will affect the safety of the car. In the prior art, the measurement of the axial clearance and assembly height of double row bearings in the assembly process is mostly manual or semi-automatic measurement, and the bearing needs to be turned 180° during the detection process to complete. Clearance detection is cumbersome to operate, and workers are prone to...

Problems solved by technology

In the prior art, the measurement of the axial clearance and assembly height of double row bearings in the assembly process is mostly manual or semi-automatic measurement, and the bearing needs to be turned 180° during the detection process to complete. Clearance detection is cumbersome to operate, and workers are prone to fatigue due to long-term work. In addition, due to the limitation of bearing measurement positions, most of them use indirect measurement methods, which are prone to insufficient measurement accuracy and poor consistency, which will affect the quality of bearings.
