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.

Embodiment Construction

[0015] Further description will be given below in conjunction with the examples.

[0016] as attached figure 1 As shown, the adjustable movable lever dial indicator stand on the test plate is mainly composed of a compression spring 1, a base 2, an adjustment screw 3, a dial indicator fixing rod 7, a support rod 8, a first collet 9, a second Collet 10, first rotary screw 11, support rod lock nut 12, second rotary screw 13, third collet 14, lever dial indicator lock nut 15, lever rib plate 16, rotary pin 17, support Rod coupling mechanism 18 is formed.

[0017] The support rod coupling mechanism 18 fixes the support rod 8 on the lever rib 16, and the third collet 14, the rotary screw 13, and the lever dial indicator locking nut 15 are used to clamp the lever dial indicator 5. The first collet 9, the second collet 10, the first rotary screw 11, and the support rod lock nut 12 are used to fix the dial gauge fixing rod 7 on the support rod 8, loosen and tighten the support rod lo...

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 ...
