The relative measuring surfaces of the two measuring boxes are separately arranged with a '-'shaped laser device and an one-dimensional PSD sensing device, and the '-'shaped laser device on one measuring surface is corresponded with the PSD sensing device on the other measuring surface, a tilt angle sensing device is assembled on the side surface of the measuring box. The power source signal of the '-'shaped laser device, the one-dimensional PSD sensing device and the tilt angle sensing device and the data signal are connected to control cable. Alignment with the utility model not only has high accuracy but also has simple utilization. With no need of adjusting the PSD sensing device to original point, the required data can be obtained by arbitrarily taking three measuring points to measure. Staking-out work is simple relative to a two-dimensional sensing device, in the same time, the cost is markedly reduced.
Description
Technical field
The utility model relates to a kind of a kind of instrument of proofreading and correct the amount of misaligning between two respective shaft in the machine shaft mating operation of two or more rotations, particularly a kind of laser alignment instrument.
Background technology
In many large-scale slewings,, also be unfavorable for the sealing of rotating shaft simultaneously because misaligning the serviceable life that can shorten bearing of machine reduces the service efficiency of machine.Traditional measuring method adopts dial gauge to carry out centering, and the naked eyes reading causes measurement inaccurate, and the long-acting rate of Measuring Time is low simultaneously.The import centering equipment of Chu Xianing has adopted laser measurement method in recent years, and measuring accuracy has been improved greatly, has quick, easy characteristics simultaneously, can replace traditional measuring method fully.But all be to adopt the Two-dimensional PSD sensor in the import centering instrument, two of main existence are obviously not enough, and the one, big, the trouble of the workload of Two-dimensional PSD transducer calibration, the while precision also is lower than one dimension PSD sensor, the 2nd, costing an arm and a leg of Two-dimensional PSD sensor is tens times of one dimension PSD sensor.
The utility model content
The purpose of this utility model provides a kind of laser alignment instrument, improve precision (precision of one dimension PSD sensor own is higher than the Two-dimensional PSD sensor), easy to use, do not need to adjust the PSD sensor to initial point, appoint and to get three measurement points and measure the data that just can obtain needs, staking-out work is simple, and cost significantly reduces simultaneously.
The purpose of this utility model is achieved by the following technical solution: two measuring units all are provided with and are fixed in two fixed supports on the measurement axis, connect measuring box by fixed bar on the fixed support, yi word pattern laser instrument and one dimension PSD sensor respectively are set on the two measuring box relative measurement faces, and the yi word pattern laser instrument on the measurement face is corresponding with the PSD sensor on another measurement face, obliquity sensor of assembling on the side of a measuring box; The yi word pattern laser instrument in two measuring boxes and the power supply signal and the data-signal of one dimension PSD sensor and obliquity sensor are connected to umbilical cable.
The utility model has the advantages that: not only the centering precision improves (precision of one dimension PSD sensor own is higher than the Two-dimensional PSD sensor), and easy to use, does not need to adjust the PSD sensor to initial point, appoints to get three measurement points and measure the data that just can obtain needs.The relative Two-dimensional PSD sensor of staking-out work is simple, and cost significantly reduces simultaneously.
