A kind of measuring tool and measuring and processing method for rotating body fork lug bushing

Abstract

The invention provides a rotary body fork lug bushing measuring tool and a measuring and processing method. The tool comprises: a base plate (2), a process bushing (4), a reference mandrel (6), a positioning mandrel (7), and a center positioning block (8) and a distance measuring device; the positioning hole on the bottom plate (2) is provided with a central positioning block (8), which is used to be clamped in the rotating hole of the rotating body workpiece (1) to fix the rotating body workpiece (1). On the base plate (2); the positioning mandrel (7) passes through the direction hole on the base plate (2) and the direction hole on the rotating body workpiece (1); the process bushing (4) is used to pass through the rotating body workpiece in turn (1) in the through holes on both sides of each fork lug; the distance measuring device is used to measure the gap between the process bushing (4) and the reference mandrel (6); the two gap values ​​corresponding to each fork lug are used To indicate the machining of swivel lug bushings. It can solve the problem that the rotating body no longer has the conditions for re-processing after the bushing is installed.

Description

technical field [0001] The invention belongs to a mechanical assembly process method, in particular to a measuring tool and a measuring and processing method for a rotating body fork lug bushing. Background technique [0002] The symmetry of the rotating body fork lug to the central axis has a great influence on the installation position of the fork lug. Therefore, it is very important to ensure high-precision symmetry after the fork lug is installed with the bushing. In order to meet this requirement, the method of secondary machining of the bushing on the CNC machine tool after the bushing is installed is generally adopted. [0003] However, this method has the following problems: after the bushing is installed, it still requires secondary repair processing and occupies equipment resources; and if the rotating body datum is covered or cannot be immersed in coolant, this method is not applicable. SUMMARY OF THE INVENTION [0004] The invention provides a measuring tool a...
