Embodiment Construction

[0029] Such as figure 1 , figure 2 As shown, the fixed plate 9 is installed on the air flotation guide rail 3, the Y-shaped cone plunger is installed on the fixed plate to install the fixed module 8, the cone plunger 6 is placed on the Y-shaped cone plunger installation and fixed module 8, and the air flotation guide rail 3 There are two sensor fixing modules 1 on both sides. The transmitting end 7 of the line laser scanning sensor LS9030 and the receiving end 5 of the line laser scanning sensor LS9030 are installed above the sensor fixing module 1 respectively.

[0030] The line laser scanning sensor LS9030 transmitting end 7 and the line laser scanning sensor LS9030 receiving end 5 used in the present invention have high-speed sampling and tilt correction functions. The sensor measurement distance is 0.08 to 30 mm, and the measurement accuracy is 2 μm, which ensures high-precision measurement of parts . The straightness of the air bearing guide rail 3 is 0.2 μm, and the e...

Abstract

The invention discloses a contour processing error measuring device and method of a hydraulic cone piston of an excavator. A cone piston part is fixed at a Y type cone piston mounting and fixing module; a line laser scanning sensor LS9030 carries out scanning to obtain contour information of the cone plunger part; a collected image is processed; contour parameters of the cone plunger part are calculated; and thus a contour processing error of the cone plunger is calculated.

Description

technical field [0001] The invention relates to a contour machining error measuring device, in particular to an excavator hydraulic taper plunger contour machining error measuring device. Background technique [0002] In recent years, the research work on contour machining error measurement has been carried out in many scientific research institutes, and the contour machining error measurement of excavator hydraulic cone plunger involves construction, coal, water conservancy, and other industries. [0003] At present, the methods for measuring the machining error of the hydraulic cone plunger of the excavator mainly include mechanical methods, optical measurement methods, and video methods. Among them, the mechanical method is easy to use and easy to carry, but its sensitivity is low, and it is not suitable for high-precision machining error measurement; the optical measurement method has high precision, high sensitivity and non-contact detection, but the structure of the op...
