The precision measuring device comprises a measuring device body, which comprises a base (1) and a control platform (13) disposed on the base. The upper part of the control platform is provided with a control panel (12), a gas floatation main shaft (6), and a gas flotation vertical column guide rail (10). The upper part of the gas floatation main shaft is provided with an aligning leveling working bench (7), and the front part of the gas floatation vertical column guide rail is horizontally provided with a horizontal guide rail (11). The front end part of the horizontal guide rail is provided with a sensor support (9), and a sensor (8) is connected with the horizontal guide rail by the sensor support. A lower computer (3) is connected with the precision measuring device by a USB and Ethernet, and is used to feed information back to an upper computer. A computer display (4) is used for real-time display. The precision measuring device is not limited by an industrial computer, and has advantages of high precision, easy operation, stable transmission, and high transmission efficiency.

Description

technical field [0001] The invention relates to the technical field of industrial large-size outer diameter and inner diameter measurement, in particular to a precision measurement device based on roundness cylindricity and a measurement method thereof. Background technique [0002] Although the traditional roundness and cylindricity measuring instrument adopts the structure of air-floating shaft system and air-floating column, the angular stiffness of the shaft system is poor, and its load bearing is slightly deviated, which affects the measurement accuracy, and further can cause the shaft system to tilt and cause jamming. Stalled, unable to move. At the same time, more of its column system adopts spring adjustment mechanism, its stability is difficult to guarantee, and the traditional sensor bracket is not suitable for end face measurement and deep hole measurement. On the other hand, the acquisition and control systems of the traditional roundness and cylindricity measur...

Problems solved by technology

[0002] Although the traditional roundness and cylindricity measuring instrument adopts the structure of air-floating shafting and air-floating column, the angular stiffness of the shafting is poor, and its load is slightly deviated, which will affect the measurement accuracy and further cause the shafting to tilt and jam stagnant, unable to move

At the same time, the column system uses more spring adjustment mechanisms, and its stability is difficult to guarantee, and the traditional sensor bracket is not suitable for end surface measurement and deep hole measurement

On the other hand, the acquisition and control systems of traditional roundness and cylindricity measuring instruments are all based on PCI or PCIe slots, and must be used with computers with PCI or PCIe slots, but commercial computers or other general-purpose computers popular on the market It does not fully have the above-mentioned slots, so that the user of the instrument must use the industrial computer as the backup computer of the instrument, and cannot choose the computer flexibly, thereby increasing the cost of the equipment, and it is not convenient for customers to use and after-sales maintenance; at the same time, the traditional roundness The human-machine interface and operability of the software used in the cylindricity measurement system adopt the traditional integrated system interface of control, acquisition and analysis, and the interface is not friendly and the user experience is poor
