A Comprehensive Measuring Instrument for Tapered Roller Bearing Inner Ring Large Rib

Abstract

The invention discloses an integrated measurement instrument of an inner-ring large flange of tapered roller bearing. The integrated measurement instrument comprises a pedestal, a workbench, a workpiece installation mechanism and a measurement mechanism. A Y-direction guide rail and a Y-direction positioned are installed at the upper end surface of the pedestal; the workbench is installed on the Y-direction guide rail through a movable support leg with an adjustable length and a fixed support leg, the movable support leg is of a stud structure and is provided with a Z-direction positioned, and the workbench is enabled to adjust an inclination angle; a workpiece positioning mechanism comprises a positioning frame, a pair of positioning screw rods, a fixed positioning pin and a movable positioning pin; and the measurement mechanism comprises an upright column, a measurement arm, a center position display instrument and a measurement instrument. According to the invention, whether the center position of a workpiece is adjusted in place can be observed through the workpiece center position display instrument; and the center position of the workpiece can be fixed through the fixed positioning pin, the movable positioning pin and the pair of positioning screw rods. The integrated measurement instrument provided by the invention can finish dimension deviation, angle deviation and linearity measurement of the large flange only through adjustment once.

Description

technical field [0001] The invention relates to a comprehensive measuring instrument for the large rib of the inner ring of a tapered roller bearing. Background technique [0002] With the development of science and technology, there are more and more bearing products, and manufacturers have higher and higher requirements for bearing tests. People are also increasingly aware of the importance of bearing tests. In the stage of bearing product development, what is to be done is the test of the bearing structure. Whether the test product can meet the working conditions of its bearing is mainly the assessment of the bearing structure. After the product finalization test, it is mainly to assess the quality of the bearing, identify the quality level of the bearing product, and promote the improvement of the quality, so as to find the problem in a weak link such as the bearing structure, material, and manufacturing process, and control it. Therefore, the bearing test is an indisp...

AI Technical Summary

Problems solved by technology

[0005] The above detection methods have the following deficiencies: ① The measurement of angle and linearity cannot be combined into one, and two instruments are required for measurement; ② The workpiece to be measured can only be detected in the measuring room, and cannot be used for detection on the processing site;

[0006] 3. For the measurement of the height of the large rib of the inner ring, the on-site inspection is measured with a special instrument for bearings, and its disadvantage is that the size transmission accuracy is low;

[0007] 4. For the processing site, the existing detection method is to use a custom-made sample through the light gap method. The disadvantage is that it is qualitative but not quantitative. It is affected by the workshop environment, light color and intensity, and includes personal experience factors.
