Description
Technical field
This utility model belongs to engine bench test technical field, and in particular to a kind of electromotor quick centering device.
Background technology
The centering of traditional electromotor is installed generally two ways：Rough and accurate.The useful ferrum of rough method
Circle drawn by silk or normal disc relies on micro-judgment than counterpart method, although quickly but degree of accuracy is very low, and with certain peace
Full hidden danger；Accurate method is mainly fixed on the accurate circular shaft in center or disk, then to electromotor using a dial gauge
The upper excessive flange being connected with power transmission shaft is measured, and the measurement need be sent out with measurement on end face in the circumference of excessive flange respectively
The concentricity and angular error of motivation, is then adjusted accordingly to engine location according to two kinds of error values respectively, but
During actual adjustment, it is difficult to reduce by two kinds of errors simultaneously, often have the phenomenon that attends to one thing and lose sight of another and occur, so need respectively to circumference
Repeated measurement is done with end face, is adjusted repeatedly, high precision but tedious process, prolonged installation cause conventional efficient too low.
Traditional approach has following Railway Project：
1st, property and rapidity become a kind of contradiction really electromotor centering to be installed, it is impossible to be incorporated into；
2nd, during adjustment engine location, people does not know the influence degree to error, can only be after adjustment
Measurement just can know that again；
3rd, with the increase of pendulous frequency, the precise decreasing of centralising device itself, it is impossible to ensure accuracy；
4th, service life is short, and the utilization rate of part is low；
5th, operator are had high demands, experience that need be certain can just be correctly completed.
Content of the invention
Technical problem to be solved in the utility model is to provide a kind of electromotor quick centering device, can pass through intuitively
The disposable continuous adjustment of reaction can complete the centering work of electromotor.
In order to solve above-mentioned technical problem, this utility model is adopted the following technical scheme that：
A kind of electromotor quick centering device, including bolt 1, to mid-game 2, check and correction regulating bolt 3, dial gauge 4, tight

12, described centering main shaft 10 goes gap thimble 6 to connect through the cylinder of centring spool 7 with centering main shaft 10 through centring spool 7
Touch, bracket base 9 is fixedly supported on below centring spool 7, and one end of centering main shaft 10 is fixedly connected with limited block 8, the other end
It is connected with to mid-game 2 by fastening bolt 5, mid-game 2 is made up of the first concentric disk 21 and the connection of the second disk 22, the
The front surface of two disks offers the hole for being coaxial therewith the heart, is arranged on described reference disk(-sc) 11 on the face relative with the second disk 22
There are one section of axle corresponding with hole 23, described bolt 1 and check and correction regulating bolt 3 to be threadedly coupled with centering disk, position
Bolt 1 offers axial through hole with check and correction regulating bolt 3, and two through holes are coaxial；The probe of described dial gauge 4 is passed through
The through hole of the through hole and bolt 1 of check and correction regulating bolt 3, and be welded as a whole with the through hole of check and correction regulating bolt 3, with positioning
The through hole of bolt 1 is contactless, and stop nut 12 is threadedly coupled with check and correction regulating bolt 3.
Described to being provided with 4 dial gauges 4 in mid-game 2.
Have the beneficial effect that：
This utility model is integrated with dial gauge on to mid-game, can constantly reflect state value；Check and correction governor motion is increased,
Replaceable, regulation, check and correction, fastening dial gauge；A disk is being increased to mid-game front end, is being matched somebody with somebody with the round shrinkage pool of its excessive flange
Close and use, it is ensured that concentricity；Gap thimble is increased, the rigging error between centering main shaft and centring spool is eliminated；Increase
Reference disk(-sc), prevents long-time using the decline of the device precision；Mid-game will be separated with centering main shaft, convenient maintenance is changed.
This utility model, can disposably be connected by intuitively reacting to concentricity and the repeated multiple times measurement of angular error without the need for respectively
Continuous adjustment can complete the centering work of electromotor, quick and precisely, and be more suitable for life-time service and maintenance.
Description of the drawings
Structural representations of the Fig. 1 for this utility model electromotor quick centering device.
Specific embodiment
Of the present utility model specific embodiment is described in detail below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of electromotor quick centering device, including bolt 1, to mid-game 2, check and correction regulating bolt 3,
Dial gauge 4, fastening bolt 5, remove gap thimble 6, centring spool 7, limited block 8, bracket base 9, centering main shaft 10,11 and of reference disk(-sc)
Stop nut 12, described centering main shaft 10 remove gap thimble 6 through cylinder and the centering master of centring spool 7 through centring spool 7
