Problems solved by technology

However, in the assembly line length detection device, because the assembly line is constantly moving, the workpieces to be detected placed on the assembly line, especially some light-weight workpieces, will move relatively on the assembly line, and even weak relative motions may cause Affects the accuracy of the detection results, therefore, it is necessary to solve the problem of relative motion of the workpiece to be tested on the assembly line

Abstract

The invention provides a length detection device, which includes an assembly line workbench, several length detection fixtures arranged on the assembly line workbench, and a length detector arranged on one side of the assembly line workbench, and the length detection fixture includes a bottom plate , a first clip, a second clip and several adjustment pieces, the first clip is a long straight profile with an L-shaped cross section, and the first clip snaps its L-shaped bend to the bottom plate On one side of the bottom plate; the adjustment piece is arranged on the surface plane of the bottom plate and is perpendicular to the first clip, and a free end of the adjustment piece is formed by abutting against the first clip and one side of the bottom plate in the gap and can move freely along the horizontal plane of the bottom plate in the gap; the second clip is set on the surface plane of the bottom plate and is perpendicular to the first clip; the bottom plane of the bottom plate is provided with the Describe the texture of the surface of the assembly line workbench. The detection result of the device of the invention is accurate and the error is small.

Description

technical field [0001] The present invention relates to a detection device, more particularly, to a length detection device. Background technique [0002] In the precision workpiece processing industry, it is necessary to measure the length of the processed workpiece. Nowadays, the laser length measurement method is often used, because the coherence of the laser is very good, the length can be measured precisely, and the range of the length that can be measured is also large, which can reach more than ten meters or even hundreds of meters. And the wavelength of the laser is short, the measurement accuracy is high, and the error is small. [0003] At present, laser length detectors are mostly used in assembly line length detection devices. The assembly line detection length is more efficient, and it saves manpower and reduces costs. However, in the assembly line length detection device, because the assembly line is constantly moving, the workpieces to be detected placed on ...
