Abstract
The utility model relates to a device for measuring and adjusting the concentricity of an air cylinder and a slide way of a reciprocating compressor, which belongs to a novel device which is used when the reciprocating compressor is installed and overhauled. The central lines of the air cylinder and the slide way are displayed through an independent special center adjusting device which changes a visional axis to a real axis; then, the centering and aligning functions of a shaft coupler of a laser measuring device are combined to measure and adjust the concentricity of the air cylinder and the slide way. The method has the advantages of exact measurement, high precision, real-time display, adjustable measuring result, estimable error and simple operation, and compared with the general method, work efficiency is increased by five times. The utility model can be used for measuring the concentricity of air cylinders and slide ways of horizontal reciprocating compressors with different cylinder diameters.
Description
The utility model relates to a kind of cylinder of reciprocating compressor and measurement and the adjusting gear and method of slideway concentricity of being applied to, and belongs to installation, maintenance a kind of new device that reciprocating compressor adopted.
Cylinder and slideway concentricity measuring method that present reciprocating compressor is adopted, be " photoelectric method ", promptly between slideway and cylinder, draw a steel wire, suspend in midair its tension with the weight of respective quality at two ends, by battery, miniature bulb and lead micrometer inside caliper being connected with steel wire is a loop, determines by distance and the bulb brightness measured on cylinder, the slideway inside surface between four points and steel wire whether steel wire is positioned at the center of cylinder, slideway and is adjusted to the standard of reaching.
Though domesticly continue to use traditional " photoelectric method " and measure always, but the shortcoming of this method is the repeated relatively poor of measuring accuracy and measurement result, efficiency of measurement is low, calculating is numerous and diverse, measuring error is difficult to estimate, especially in little cylinder diameter, big span occasion, " photoelectric method " just more is not suitable for execute-in-place.
The purpose of this utility model is just in order to solve weak point of the prior art, and proposed a kind of " laser method ".This " laser method " provides a kind of special-purpose laser alignment instrument alignment device (showing as Fig. 1), air feed cylinder, slideway use respectively, it can show with the form of axle in kind, and then realize the measurement and the adjustment of cylinder and slideway concentricity at an easy rate touching less than, invisible cylinder, slideway center line.
The purpose of this utility model is achieved in that
" laser method " measurement mechanism is made up of adjuster bar, dummy shaft, high-precision rolling bearing and laser target etc.Special dial gauge wherein has been installed on the dummy shaft, and indicator is beaten on slideway and cylinder inner wall.At first judge the actual deviation of dummy shaft center line and measured object (cylinder, slideway) center line, utilize shaft coupling centering principle to carry out concentricity then and measure adjustment by the dial gauge reading.
The purpose of this utility model can also be further perfect by following steps:
Adjuster bar in " laser method " and dummy shaft link are to be threaded; By each adjuster bar of accurate adjustment, deviation is revised.When the reading variation range of the back dial gauge that rotates a circle is no more than 0.01mm, can think a bit overlapping on this point and measured object (cylinder, slideway) center line on the dummy shaft, survey again and a bit can think the center line and corresponding dummy shaft central lines of cylinder, slideway, utilize the shaft coupling centering function of laser alignment instrument to carry out the concentricity measurement and adjustment in real time of cylinder and slideway then, up to reaching standard.
The utility model has a width of cloth accompanying drawing, is most preferred embodiment of the present utility model, also can make the accompanying drawing of specification digest.
Fig. 1 is a structural representation of the present utility model.
The utility model compared with prior art has following advantage:
(1), can supply multiple measurement; (2), " the change imaginary axis is real axis " is special With transferring the center alignment device, with cylinder, slideway after to the accurate adjustment of centering frame Center line " clear ", recycling shaft coupling centering principle carry out cylinder, The measurement of slideway concentricity; (3), simple to operate, measure accurately, directly perceived, Effect can improve 5 times, can satisfy specification requirement; (4) also can be used for difference The concentricity of the cylinder-slideway of the horizontal opposed reciprocating compressor of cylinder diameter is measured.
Below in conjunction with accompanying drawing most preferred embodiment of the present utility model is further described:
Most preferred embodiment of the present utility model as shown in Figure 1, its groundwork principle is to select the adjuster bar of different length (3) for use, high-precision rolling bearing (1) is equipped with at dummy shaft (5,8) two ends, make it to rotate freely, adjuster bar and dummy shaft link are to be threaded, by adjuster bar, can realize the accurate adjustment in dummy shaft axle center.Special dial gauge assembly (2) has been installed on the dummy shaft, and indicator is beaten on the inwall of slideway (7) and cylinder (6).During adjustment, the rotation dummy shaft, by the actual deviation value of dial gauge reading judgement dummy shaft center line and measured object (cylinder, slideway) center line, each adjuster bar of accurate adjustment is revised deviation then.When the reading variation range of the back dial gauge that rotates a circle is no more than 0.01mm, can think a bit the overlapping of this point and measured object (cylinder, slideway) center line on the dummy shaft, survey again and a bit can think the center line and corresponding dummy shaft central lines of cylinder, slideway, utilize at last the laser target (4) installed on the dummy shaft according to shaft coupling centering principle to the concentricity of cylinder and slideway measure, adjustment.
Slideway is owing to be made up of two arc surfaces on the circle, so the support bar of its centering frame and cylinder is slightly different, be three bar vertical direction symmetrical expressions, and the bracing frame of cylinder is that three bar circumference are evenly distributed.
Claims (1)
1, the concentricity laser measurement alignment device of compresser cylinder-slideway, it is characterized in that: design a cover voluntarily and adjust center fixture, with its by with the ingenious combination of a cover laser alignment instrument, realize reciprocating compressor cylinder-slideway concentricity precision, fast measure and adjust in real time.It is adjusted center fixture and is made up of dummy shaft, adjuster bar, high-precision rolling bearing, dial gauge assembly, high-precision rolling bearing is installed in the dummy shaft two ends, by thread connecting mode 3 adjuster bars are linked to each other with bearing outside, adjuster bar is supported in to be measured circumferential inner surface, the dial gauge bar is fixed on the dummy shaft with thread connecting mode, dial gauge is installed on the table boom end, and its indicator contacts with surface measurements, and the laser target of laser alignment instrument then is fixed in the dummy shaft end face by being threaded.By the assembling of above-mentioned each parts, thereby constituted all technical characteristic of this device.
