Ball slide block measuring device and method

Abstract

The invention discloses a ball slide block measuring device and method. The measuring device comprises a rectangular frame and a slide block positioning assembly, the slide block assembly is composed of a fixed seat, a mobile seat, a mobile auxiliary member and two measuring heads, the two measuring heads are arranged on the fixed seat and the mobile seat symmetrically, the fixed seat is fixed in the left side of the internal bottom side of the rectangular frame, the mobile auxiliary member is mounted in the right side of the internal bottom side of the rectangular frame, the mobile seat is arranged on the mobile auxiliary member, a pressure spring is arranged between the fixed seat and the mobile seat, the external surface in the upper portion of each measuring head is provided with upper and lower arc chutes corresponding to upper and lower raceways of a ball slide block, the upper and lower arc chutes are provided with measuring rods whose radius is the same with that of a ball respectively, a fastening screw which enables the mobile seat to move left and right is arranged in the right side of the rectangular frame, the upper and lower measuring rods are fit to the corresponding upper and lower raceways under effect of the pressure spring, measuring tool locking seats are mounted in top, left and right sides of the rectangular frame respectively, and dial gauges are mounted on the measuring tool locking seats respectively. The measuring device and method have the advantages that the measuring efficiency can be improved, and many error factors can be eliminated to improve the measuring precision.

Description

technical field [0001] The invention relates to a part measuring technology in a ball linear guide pair, in particular to a measuring device and a measuring method of a ball slider, which can quickly and accurately measure various dimensions of a concave-shaped ball slider. Background technique [0002] With the advancement of "Industry 4.0" and the national strategy "2025", automation, high integration, high precision, and quick response equipment are also emerging one after another, and ball linear guides play an important role in it. With the rapid development of processing technology, the requirements for the measurement accuracy and measurement efficiency of the main parts of the ball linear guide pair, the guide rail and the ball slider, are getting higher and higher. Especially the ball slider, due to its special shape, a single measuring tool cannot be directly measured. The traditional method of measuring the raceway of the ball slider is to use a measuring rod, a ...

AI Technical Summary

Problems solved by technology

The slider raceway measuring device and its working method are more convenient than the traditional slider raceway measurement method, and can directly measure the position size of the slider raceway. However, through the slider raceway measurement device and its Working method When measuring the slider, it is necessary to plug the wedge-shaped rod tightly and take a micrometer to perform manual measurement, which has certain troubles; Will affect the measurement accuracy
