Abstract

The invention relates to a device for determining the verticality of honeycomb ceramics. The device comprises an upper laser emitter, a lower laser emitter, a first support, a vertical reference body, a rotary sample plate, a motor, an upper laser receiver, a lower laser receiver, a second support, a signal processor and a display unit, wherein the upper laser emitter and the lower laser emitter are connected with the first support in a sliding mode; the upper laser receiver and the lower laser receiver are connected with the second support in a sliding mode; the rotary sample plate is horizontally positioned between the lower laser emitter and the lower laser receiver; the motor drives the rotary sample plate to rotate through a transmission mechanism; the vertical reference body is vertical to the rotary sample plate and is positioned between the lower laser emitter and the lower laser receiver; and signal output ends of the upper laser receiver and the lower laser receiver are connected with a signal input end of the signal processor, and a signal output end of the signal processor is connected with a signal input end of the display unit. The device can be used for determining the verticality of the honeycomb ceramics with round, elliptic and rectangular cross sections, and the testing efficiency is quite high.

Description

Technical field [0001] The invention relates to a device for measuring the verticality of honeycomb ceramics. Background technique [0002] Verticality means that the measured element on the part maintains the correct 90° angle with respect to the reference element, that is, the degree of orthogonality between the two elements is usually said. Perpendicularity is the shape tolerance, that is, the maximum variation allowed between the actual direction of the measured element and the ideal direction perpendicular to the reference. At present, there are many types of measuring instruments with a tolerance of perpendicularity greater than 0.05mm, and the tolerance of less than 0.05mm is usually measured by a coordinate measuring machine. The report on verticality testing equipment is as follows: [0003] CN101581568 discloses a perpendicularity detector for detecting the perpendicularity of one end surface of a workpiece with respect to a certain reference surface on the workpiece.

Problems solved by technology

[0008] Honeycomb ceramics are a kind of porous ceramics, which are widely used as catalyst carriers for vehicle exhaust purification and various combustion furnace regenerators, but they have many cross-sectional shapes, are easily broken, and have poor strength.

The physical and chemical properties, external dimensions, perpendicularity and parallelism of honeycomb ceramics directly affect its use. So far, there has been no report on the method and device for measuring the perpendicularity of honeycomb ceramics.
