Abstract

The invention discloses a pneumatic roll gap instrument. The pneumatic roll gap instrument comprises a ruler body and a ruler frame. The ruler body is connected with the ruler frame through a dovetail groove. The ruler frame can slide vertically on the ruler body. A single-acting cylinder is arranged in the ruler body. A side hole of the ruler body corresponds to an air hole of the single-acting cylinder. The head of a piston rod of the single-acting cylinder is connected with a connecting plate. An upper benchmark arc plate is fixed to the upper end of the connecting plate. A reading device is fixed to the lower end of the connecting plate. A lower benchmark arc plate is arranged at the lower end of the ruler body. The upper benchmark arc plate and the lower benchmark arc plate are respectively provided with three guide rails. The guide rails are evenly distributed on the upper benchmark arc plate and the lower benchmark arc plate. The pneumatic roll gap instrument is simple in structure, convenient to operate, high in accuracy, low in cost and suitable for popularization.

Description

technical field [0001] The invention relates to a measuring instrument, in particular to a pneumatic roll gap meter. Background technique [0002] Metallurgical enterprises and metal processing industries mostly extrude the slab with upper and lower rollers to achieve the required thickness or shape of the product. There must be strict precision requirements for the opening degree and symmetry of the upper and lower rollers. If the error of the upper and lower rollers does not meet the requirements, the product will seriously deviate after entering the roller table, the thickness of the pressed finished product will be inconsistent, and the quality will not meet the qualified standard. At this stage, most related enterprises use electronic roll gap meter to measure the opening and symmetry between two rolls. The electronic roll gap meter has high precision and clear readings. This instrument is the first choice of related enterprises. However, the electronic roll gap met...
