Problems solved by technology

The principle of this method is correct, but because the end face of the ring is perpendicular to the grinding groove surface, the instrument using the Cartesian coordinate contact method to measure the contour will bring relatively large errors in the measurement and evaluation, and it is difficult to achieve high-precision measurement of the groove position of the bearing ring

Embodiment Construction

[0016] The measuring device used to realize the contact measuring method of precision measuring bearing ring groove position of the present invention consists of a workbench 1, a V-shaped groove table 2, a standard ball 4, a groove position measuring bracket 5, a locking screw 6, a baffle plate 7 and an inductance The sensor 7 constitutes.

[0017] combine Figure 1-2 Firstly, place a workbench 1 with a semi-arc groove on the profiler, and set a V-shaped groove table 2 on the upper end of the semi-arc groove workbench. The V-shaped groove table 2 can rotate along the semi-arc groove of the workbench 1. It can move horizontally along the length direction of the semi-arc groove of the workbench. A baffle 7 is installed at the left end of the V-shaped groove table 2. There is a straight groove in the middle of the baffle 7 in the vertical direction. The vertical center line of the straight groove of the baffle plate is aligned with the V-shaped groove table. The center line of t...

Abstract

The invention provides a contact type measuring method for precisely measuring position of a bearing ferrule trench. A worktable (1) and a V-type groove table (2) are provided, the V-type groove table is installed with a baffle (7), a trench position measuring bracket (5) moves up and down along the baffle and is fixed by a locking screw (6), and a standard ball (4) with the semi-diameter of R isfixed at the cantilever end of the trench position measuring bracket. Fine adjusting is carried out to lead bus lines of the standard ball and a standard column rod arranged on the V-type groove table to be axially superposed, an inductance sensor (8) which can horizontally move is fixed above the standard ball, and a measured ferrule (3) with the measured width of H is taken and placed on the V-type groove table. Suppose the standard ball is respectively tangential to the end faces A and B of the measured ferrule so as to obtain the trench circular arc center distance LA and LB in a measuring manner, the position size corrosion value E of the measured ferrule is obtained and stored into a computer for other measured ferrules to be detected in the same batch, and the actual trench position size W(any)` from any end face of other measured ferrules to a circular arc of the trench equals to W(any) minus E and equals to L(any) minus R minus E.

Description

technical field [0001] The invention belongs to the technical field of bearing ring measurement, in particular to a contact measurement method for precisely measuring the position of a bearing ring groove. Background technique [0002] The bearing ring groove position refers to the distance from the end face of the ring to the center of the groove. At present, the following methods are used to measure the position of the bearing ring groove: [0003] 1. Use the inversion method to measure through the length measuring instrument. The reverse method measurement method is to measure the position of the ring groove by comparing the position difference from the bottom of the bearing ring groove to the two ends of the ring and the total width of the ring. The measurement is relatively accurate, but it is cumbersome and not suitable for the same type of manufacturer. Batch detection. [0004] 2. Measured by a contact profiler. The measurement method of the contact profiler is t...
