Embodiment 1

[0040] A workpiece is a cylindrical part, its outer wall is a metal structure, the inner wall is a glass fiber reinforced plastic structure, its axial length is close to 1000mm, and its diameter is less than 70mm. When using manual measurement of wall thickness, put the cylindrical part on the measuring mandrel, use the dial gauge to withstand the outer wall, and at the same time apply radial force manually to make it close to the measuring mandrel, because the dial gauge and measuring mandrel If the zero position is calibrated between, the reading of the dial gauge is the wall thickness. This method cannot be automated and continuous measurement, and the efficiency is low and a large number of dial gauge heads are worn.

[0041] And use the cylinder wall thickness automatic measuring device based on laser sensor described in the present invention, from loading (furnished with automatic loading and unloading manipulator in addition), to the clamping of workpiece, location and m...

Abstract

The invention discloses an automatic cylinder wall thickness measurement device based on a laser sensor. The device comprises a machine frame, a transmission unit, a rotating mechanism, a guide bearing mechanism and a measurement and adjustment mechanism. On one hand, the defect that a measurement instrument is abraded due to contact measurement is overcome, on the other hand, influences of unevenness of materials on measurement precision are avoided, measurement efficiency and precision are greatly improved, and automatic pipelining measurement is easy to achieve. The measurement device is improved in the following aspects: (1) the transmission structure of the measurement device and the motion relation between the laser sensor and a workpiece to be tested, (2) the distribution and automatic measurement feeding mode of the laser sensor, (3) automatic positioning, clamping and rotating of the workpiece to be tested and the anti-collapsing or anti-tilt structure, and (4) function extensibility, measurement universality and implantation of an automatic production line. The measurement device has the advantages of being simple in structure, high in reliability and easy to obtain.

Description

technical field [0001] The invention belongs to the field of automatic precision measurement, and relates to an automatic and precise measurement device for cylinder wall thickness based on a laser sensor. Background technique [0002] A large number of cylindrical parts are involved in civil industry and national defense equipment, such as pneumatic cylinders, hydraulic cylinders, gun barrels, missile shells, etc. Especially for slender cylindrical parts, due to the semi-closed structure of the workpiece itself, it is difficult to measure the wall thickness. [0003] At present, there are mainly two methods for measuring the wall thickness of cylindrical parts: one is contact measurement, such as the patent document "A Device for Measuring Pipe Wall Thickness" with the patent number of 200910235928.7, etc. This contact measurement is mostly manual operation , the measurement efficiency is low, and the measured values ​​obtained are mostly discrete data, especially for work...
