Abstract

The utility model discloses an optics centering apparatus for a motor shaft coupling. The optics centering apparatus comprises a laser emission-receiver and a reflector which are mutually matched to be used, wherein the emission-receiver comprises a laser emission probe and an indication disc with scales. One surface of the reflector is a plane reflective mirror and the other surface of the reflector is a prism reflective mirror. Through a light emission characteristic, a tiny gap is amplified and measurement precision is raised; the apparatus is without expensive parts, so that device cost can be effectively reduced; and a measurement principle is simple and the optics centering apparatus can dynamically display, so that a repeated measurement and calculation process in a conventional measurement method is removed and operation convenience is improved.

Description

The optics centralising device that is used for motor coupler

Technical field

The utility model relates to a kind of optical measuring apparatus, specifically a kind of centralising device of optics for motor coupler.

Background technology

the shaft coupling alignment of motor is an important content of rotating machinery installation and maintenance work, in real work, often the aligning method of application has single table method, double meter method and genuine standard, no matter any aligning method, common characteristics are arranged: the centering in surface level internal ratio vertical plane is easily made mistakes, repeatability is strong, consuming time many, calculate loaded down with trivial details, if the method for centering not to or the centering out of true as a result of looking for, the vibration values that can cause rotating machinery exceeds standard, the normal operation of rotating machinery in serious threat, easily cause the wearing and tearing of the rotatable parts such as the vibration of machine and bearing.Laser alignment instrument, appearred in the development along with technology, but equipment manufacturing cost is expensive, restricts it and apply.

The utility model content

The purpose of this utility model is to provide a kind of centralising device of optics for motor coupler, and is easy to install, with low cost, overcomes existing supplemental measurement tool complex operation and the low drawback of precision.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is:

A kind of centralising device of optics for motor coupler, described optics centralising device comprises Laser emission-receiver and the reverberator that is used in conjunction with each other, the send-receive device comprises the laser emission probe with graduated display disc and display disc central authorities, described reverberator is simultaneously plane mirror, one side is the faceted pebble reflective mirror, described Laser emission-receiver is arranged on by support and holder on the axle of motor, and reverberator is arranged on the axle of speed reduction unit by support and holder.

The beneficial effects of the utility model are: the utility model utilizes the light emission characteristics, small gap is amplified, thereby improve the precision of measuring, do not have high parts, can effectively reduce the cost of equipment, its measuring principle is simple, and dynamically shows, save the process of repeated measurement and calculating in the traditional measurement method, improved the convenience of operation.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail:

As shown in Figure 1-2, the optics centralising device that is used for motor coupler, comprise two Laser emission-receivers that are used in conjunction with each other 100 and reverberator 200, send-receive device 100 comprises laser emission probe 102 and is with graduated display disc 101, described reverberator 200 one sides are plane mirror 201, and one side is faceted pebble reflective mirror 202.

As shown in Figure 2, motor 1 and speed reduction unit 2 are by motor coupler 3 and device coupling 4 docking.Comprise the following steps in measuring method:

Step a, described Laser emission-receiver 100 is arranged on the axle of motor 1 by support 6 and holder 5, and reverberator 200 is arranged on the axle of speed reduction unit 2 by support 6 and holder 5.

Step b, Laser emission-receiver 100 and reverberator 200 over against, and make it to be in horizontality.

step c, if two axial lines is not parallel, the laser beam of laser probe emission is through the reflection of level crossing, reflection ray can be got on the display disc of assembly A, utilize the reading on display disc, distance between Laser emission-receiver 100 and reverberator 200, motor leg spacing, and the motor leg is apart from the vertical range of reverberator 200, namely can calculate easily regulated quantity, adjusting for horizontal level, can not calculate yet, directly regulate, because laser designation is dynamic, so can accurately judge regulated quantity, regulate until the reflection ray of laser beam overlaps position with incident ray, namely reached diaxon parallel.(as shown in Figure 4)

Steps d, regulate diaxon concentric.The reflecting surface of assembly B is rotated to the prism state.(as shown in Figure 5)

Step e, the rib of prism is just consistent with the height of laser probe, if the diaxon decentraction, laser beam can shine a side of prism, through reflection, can get on display disc,, according to the indication of display disc, determine to regulate direction, until laser beam is relative with the rib of prism, the display disc laser beam disappears, thereby determines that diaxon is concentric.

Step f, horizontal direction, with related this measurement mechanism 90-degree rotation of motor shaft, turns to vertical direction after regulating and completing, and measures and control method same level direction.

Although the above is described the utility model by reference to the accompanying drawings; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment is only schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model;, not breaking away from the scope situation that the utility model aim and claim protect, can also make the concrete conversion of a lot of forms, within these all belong to protection domain of the present utility model.
