Length detection device

Abstract

The invention discloses a length detection device. The length detection device comprises a substrate, a guide rail, a detection measuring tool, a fixed plate, a movable plate, a touch switch, an alarm apparatus and an oil cylinder, wherein the guide rail is arranged on the substrate; the detection measuring tool is fixed on the upper plane of the guide rail through bolts; the fixed plate is tightly attached to the end face of one end of the guide rail; the movable plate is arranged above the guide rail and moves left and right along the axis of the guide rail; the touch switch is arranged in the middle of the inner side of the movable plate, and the touch switch and the plane of the inner side of the movable plate are in the same horizontal plane; the oil cylinder is fixed above an engine base and is connected with the movable plate; the alarm apparatus is arranged on the upper end face of the movable plate and is connected with the touch switch. In this way, the length detection device disclosed by the invention can guarantee that the error value of object length detection size and practical processing size is the minimum to reach a high-standard detection requirement; meanwhile, the length detection device can further detect products with different lengths, and is wide in application range, convenient to detect, high in precision and easy to operate.

Description

Technical field [0001] The invention relates to a detection tool, in particular to a length detection device. Background technique [0002] Length detection is the longest part size detection used in mechanical processing. The current quantities used for length detection include vernier calipers, scales, tape measures, etc., but in the specific detection process, due to the large deviation of manual visual inspection, it leads to The measuring tool has a large size error, and it can fully meet the measurement requirements for parts that are not demanding in the use occasion, but it cannot meet the measurement requirements for parts that require high length and accurate accuracy. Summary of the invention [0003] The main technical problem solved by the present invention is to provide a length detection device that can ensure that the error value between the length of the object and the actual processing size is minimized, so as to meet the high standard detection requirements, and...

Problems solved by technology

[0002] Length detection is the longest used part size detection in machining. At present, there are vernier calipers, scales, tape measures, etc. for length detection. However, in the specific detection process, due to large deviations in manual visual inspection, resulting in its The size error of the measuring tool is large, and it can fully meet the measurement requirements for parts with low requirements in the use occasion, but it cannot meet the measurement requirements for parts with high length requirements and accurate accuracy.
