General three-coordinate tool for measuring side plate product

Abstract

The invention discloses a general three-coordinate tool for measuring a side plate product. A guide rail, a strut and a cantilever are connected by threads to form a frame with an opened edge; a cantilever end is provided with a compacting and adjusting mechanism; and the guide rail is provided with a support limiting mechanism. The compacting and adjusting mechanism ensures that the product does not deform during clamping, and the reliability and the repeatability for detecting data can be ensured; the support limiting mechanism has a favorable positioning function and is convenient to operate; corresponding brackets are replaced for different types of products; the products with the same type can be programmed for one time and can be recycled. The tool is suitable for batch detection, and the detection efficiency is improved. The general tool is not only suitable for the detection of the side plate products, but also suitable for the detection of part non-side plate products, such as gear rings and shaft sleeves.

Description

technical field [0001] The invention relates to a measuring tool, in particular to a general tool for three-coordinate measuring side plate products, which belongs to the manufacturing technical field of the mechanical processing industry. Background technique [0002] Coordinate measuring machine is a new type of high-efficiency precision measuring instrument, which has become an indispensable measuring equipment for modern industrial inspection and product quality control. The side plate products, the key components of the hydraulic gear pump, are 8-shaped, thin in thickness: 1.5-10mm, large in length-thickness ratio: generally greater than 10, and require high shape and position accuracy, especially the flatness and parallelism of the two ends of the side plate , the existing pressure plate tooling of the three-coordinate measuring machine and some testing tools such as plasticine fixing, there are: 1) The pressing force is uncontrollable, causing the product to be clampe...

Problems solved by technology

The side plate products, the key components of the hydraulic gear pump, are 8-shaped, thin in thickness: 1.5-10mm, large in length-thickness ratio: generally greater than 10, and require high shape and position accuracy, especially the flatness and parallelism of the two ends of the side plate , the existing pressure plate tooling of the three-coordinate measuring machine and some testing tools such as plasticine fixing, there are: 1) The pressing force is uncontrollable, causing the product to be clamped and deformed, which affects the reliability of the measurement results; 2) There is no adjustable support Limit mechanism, the clamping and positioning of the tested product is not accurate, it is not suitable for continuous and repeated automatic measurement; for changing products of different sizes, the clamping tooling needs to be replaced, which affects the measurement speed and leads to low work efficiency

Existing patents ZL 200420029658.7, ZL 200920227810.5 and ZL 201020131055.3 cannot be applied to the detection of side panel products, and the measurement of the flatness and parallelism of both ends of the side panel cannot be completed at one time
