Adjustable and movable lever indicator bracket on test flat plate and application method thereof

Abstract

The invention provides an adjustable and movable lever indicator bracket on a test flat plate, which relates to a test device. The lever indicator bracket comprises a base, a supporting rod and a dial indicator fixing rod, wherein the supporting rod is fixed on the base; the dial indicator fixing rod is fixed on the supporting rod through a fixed adjusting mechanism, so the dial indicator fixing rod can point to the surface of a tested part at a certain angle, the dial indicator fixing rod can move up and down on the supporting rod to adjust the height, can expand along the axial direction ofthe dial indicator fixing rod to adjust the extension length of the dial indicator fixing rod; an extension end of the dial indicator fixing rod is provided with a dial indicator clamping mechanism for clamping the lever indicator; and the base is provided with a lever fine adjustment mechanism, so the lever indicator bracket slightly oscillates forward and backward to finely adjust the height ofa spherical measuring head of the lever indicator and the force pressing towards the surface of the tested part. The lever indicator bracket can be directly used for detecting the parallelism of regular parts on the test flat plate, and is very convenient and practical.

Description

technical field [0001] The invention relates to an inspection device, in particular to an adjustable movable lever dial indicator stand on an inspection board, which is mainly used for clamping a lever dial indicator to detect the parallelism of processed parts on the inspection board. Background technique [0002] The governor flyweight of a diesel engine is a special-shaped part with an irregular shape, but there are high requirements for shape and position tolerances such as parallelism and perpendicularity among multiple dimensional elements. In each link of the part manufacturing process, such as the first inspection , Self-inspection, patrol inspection, end-of-sequence inspection, factory inspection, etc. must be inspected frequently. Some dimensions are random inspections, and some dimensions are full inspections. The workload of inspections is very large. Although the detection accuracy of the three-coordinate measuring instrument is high, it is limited by funds and ...

AI Technical Summary

Problems solved by technology

Although the detection accuracy of the three-coordinate measuring instrument is high, it is limited by funds and work sites; it is feasible to use conventional detection equipment such as a lever dial indicator clamped by a magnetic table holder, or a height gauge, but the efficiency is low and it is not suitable for large quantities.
