1053 contact with datum level (surface of the minute wheel disk of engine), and pressure measuring head 1053 makes big pointer rotation be greater than a circle, rotation
Dial is aligned 0 line with big pointer, and measuring staff upper end is then lifted 1-2mm letting go again falls it, checks after 2-3 times repeatedly
Whether pointer is still aligned with 0 line, as uneven, resets；And then guarantee the first dial gauge 106 and 105 measurement data of the second dial gauge
Accuracy rate and service life.
Specifically, connecting rod includes first connecting rod 102 and the second connecting rod 104,102 first end of first connecting rod and solid
Determine the connection of frame 101, second end is connect by locking member 103 with the second connecting rod 104；Second connecting rod, 104 first end passes through lock
Tight part 103 is connect with first connecting rod 102, and second end is connect with the first dial gauge 106 or the second dial gauge 105.Wherein, first
102 first end of connecting rod is fixedly connected with fixed frame 101.
Further, first connecting rod 102 is set as universal connection rod.
Further, locking member 103 is set as locking nut.
Wherein, locking nut generally hex nut, and be threadedly coupled with universal connection rod.
It should be noted that when using the first dial gauge 106 and the second dial gauge 105, if axle center distance and center
It when height is all improper, needs to adjust the first dial gauge 106 and the second dial gauge 105, then locking nut tune pine can be adjusted
Universal connection rod is saved, the first dial gauge 106 and the second dial gauge 105 are adjusted to suitable position, then lock locking nut
Tightly, then to the axle center distance and centre-height of the minute wheel disk of engine it tests.
It should be noted that the first dial gauge 106 and the second dial gauge 105 pass through fixing piece 107 and the second connecting rod
104 connections.
It should also be noted that, fixing piece 107 is threadedly coupled with the second connecting rod 104.
In the present embodiment optinal plan, the first dial gauge 106 and the second dial gauge 105 include table body 1052, gear cap
1051 and measuring head 1053, measuring head 1053 and engine divide sheave contact.In use, by the first dial gauge 106 and second
The scale of dial gauge 105 is adjusted to the position needed, uses manpower and material resources sparingly, and be not required to be equipped with professional again to adjust
Level can reduce the research and development time, improve efficiency.
It should be noted that fixed frame 101, connecting rod and locking member 103 are all made of stainless steel material and are made.
It is being used in conjunction with can be seen that centralising device provided in this embodiment to the detailed description of the utility model above
When, fixed frame 101 is installed on dynamometer machine, the first dial gauge 106 and the second dial gauge 105 are connected to fixation by connecting rod
On frame 101, contact the first dial gauge 106 and the second dial gauge 105 axially and radially with engine flywheel disk respectively, and will
Scale on first dial gauge 106 and the second dial gauge 105 is adjusted to the position of needs, then rotates the rotating disk of dynamometer machine,
Centre-height and the axle center of engine flywheel disk are adjusted by the data variation of the first dial gauge 106 and the second dial gauge 105
Distance, only when the pointer of the first dial gauge 106 and the second dial gauge 105 is in the position of setting and when will not change, then
The centre-height and axle center distance for proving engine flywheel disk are adjusted and are finished, and adjust axial direction again without having adjusted radial direction, and
Need repeated multiple times be adjusted；The application can then be adjusted simultaneously, therefore substantially increase adjusting efficiency, and precision mentions therewith
Height, therefore solve time-consuming technical problem in the prior art.
