Description

The aligning concentricity instrument

One, technical field:

The utility model relates to a kind of shaft coupling (to wheel) and looks for the instrument of (centering) with one heart, particularly relates to the Installation and Debugging of equipment in a kind of power machine field of adopting the shaft coupling transmission and the aligning concentricity instrument of beating the steel wire knot of maintenance.

Two, background technology:

As everyone knows, in power transmission machinery, the mode that a lot of transferring power are arranged, as the permanent coupling kind of drive, because it is simple in structure, the efficient height, easy for installation, life-span is grown and is widely adopted, but the concentricity to diaxon has higher requirements, it is guaranteed by the concentricity of adjusting shaft coupling, if the diaxon Concentricity tolerance is too big, not only can produce noise and vibration, increase power consumption, also can influence the working condition of equipment, reduce service life of equipment, so the plant equipment that adopts the shaft coupling transmission all has strict requirement to the concentricity of diaxon, general big-and-middle-sized equipment axis to, radial error is all between 0.06～0.09mm, for reaching this higher accuracy requirement, generally adopt dial gauge to cooperate in the on-the-spot installation and maintenance to look for magnet stand concentric, through repeatedly reaching technical requirement after the repeated test adjustment.

Adopt dial gauge and magnetic force dial framework to look for that all kinds of corrupt practices creep in one heart: 1. the mechanical type dial gauge belongs to precision instrument, needs the periodic check through specialized department; 2. each measurement all need be readjusted and school zero, installs because of debugging very trouble; 3. need to reserve the truth of a matter, can not be from zero reading, to adjust loaded down with trivial detailsly, the value of reading is easily made mistakes; 4. the single face dial plate can not be looked at straight after the anglec of rotation, and the error and the value of reading difficulty can take place; 5. weight is big, easily slides in the rotation or comes off and damage instrument; 6. installation volume is big, and the less plant equipment of shaft coupling surrounding space can't be used; 7. symmetry is set up two instrument respectively, influences the jiggering operation and the value of reading and calculates loaded down with trivial details.

Three, summary of the invention:

The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, a kind of various drawbacks that can abandon original mechanical type dial gauge centering fully are provided, it is little to have volume, in light weight, simple in structure, easy for installation, need not return to zero, calibration, the aligning concentricity instrument of advantages such as the value of reading is directly perceived, and precision is higher, and the scope of application is extensive.

Its technical scheme is: mainly by axial probe (1), radially probe (4), probe socket (3), telescopic arm (6), retracting cylinder (8), flexible cable (9) and magnet base (10) are formed instrument calibration partly and the single-chip computer control system part; Be provided with telescopic arm (6) in the described retracting cylinder (8), and in retracting cylinder (8), slide; Axial probe (1) and radially pop one's head in (4) are installed in respectively on the probe socket (3) of telescopic arm (6), and two probes are mutually 90 degree operating angles; The signal of two probes is then drawn through flexible cable (9) to the single-chip computer control system part by the inner built-in signal line (2) of telescopic arm (6).

Be processed with guide slot (5) on the described telescopic arm (6), regulate axial probe (1) and the position of radially pop one's head in (4) by set lever (7).

Described single-chip computer control system part by signal transmission socket (20), four LED charactrons (21), power switch key (22), radial measurement pilot lamp (23), axially measure pilot lamp (24), data storage key (25), reset key (26), radially four point measurement change-over switches (27), Microcomputer Data interface (28), axial four point measurement change-over switches (29) and single-chip microcomputer are formed, and are used for signal controlling, computing, demonstration, storage.

Four LED charactrons (21) are that LED or LCD show; Radially four point measurement change-over switches (27), axial four point measurement change-over switches (29) are button change-over switch or rotation fork shift switch.

Advantages such as the beneficial effects of the utility model are: abandon the various drawbacks of original mechanical type dial gauge centering fully, it is little, in light weight, simple in structure, easy for installation to have a volume, need not return to zero, calibration, and the value of reading is directly perceived, and precision is higher, and the scope of application is extensive.Because influence the environment and the temperature of ultrasonic measurement precision, much at one, both error was identical in the one-shot measurement process, be the poor of two numbers and desire value, so just avoided Effect of Environmental; Because ultrasonic probe is in light weight, volume is little, and that the instrument calibration size can be done is less (work only takes up room to original 1/4, and weight is less than original 1/5), makes the mensuration of the narrow and small coupling system concentricity of surrounding space structure become possibility; Only need a less instrument calibration just can finish the mensuration of two values simultaneously, installs easy to carryly, measure and the demonstration split, be convenient to the installation and the value of reading owing to adopt; By single-chip microcomputer memory function is arranged, can once survey whole data, calculate at last; The scope of application, work efficiency and measuring accuracy greatly improve.
