Description
Technical Field
The utility model relates to a height measurement machine technical field, concretely relates to high-accuracy rotatory hand wheel height measurement machine.
Background
The measuring machine is the most representative measuring instrument. In the measuring machine, a mechanical coordinate system is established by taking a platform of a measuring instrument as a reference plane, coordinate values of measured points on the surface of a measured workpiece are collected and projected into a space coordinate system, and a space model of the workpiece is constructed. The measuring machine is widely applied in the field of measurement, the size of the measuring machine is determined as small as a hardware, and the measuring machine can be applied to various measuring instruments for measuring the geometric quantities of the whole machine and the whole vehicle.
When the existing measuring machine is used on the rubber block, because the rubber block and the fixed station have larger gaps, and the contact force of the contact is smaller, the measuring height of the rubber block is higher than the actual height greatly, and larger measuring errors are caused.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a high-accuracy rotatory hand wheel height measurement machine solves current measuring machine when using on the block rubber, because block rubber and fixed station have great clearance, and the contact dynamics is less moreover for the block rubber's measurement height is higher than actually needing greatly on the high side, causes the great technical problem who waits to solve urgently of great measuring error.
In order to realize the above-mentioned purpose, the utility model provides a high-accuracy rotatory hand wheel height measurement machine, include measuring machine base, fixed station, surveyed metal block, measuring machine support frame, boss, measuring arm, scale bar, contact head, rotatory hand wheel, the fixed station is installed at measuring machine base top, it fixes on the fixed station to be surveyed the rubber block, the measuring machine support frame passes through the boss to be fixed on the measuring machine base, the measuring arm is connected on the measuring machine support frame, the scale bar is installed on the measuring arm, the contact head is located the bottom of scale bar, rotatory hand wheel is connected at the top of scale bar, rotatory hand wheel clockwise rotation a week scale rises 0.01mm, rotatory hand wheel anticlockwise rotation a week scale descends 0.01 mm.
Preferably, the length of the measuring machine base is 180mm, and the width of the measuring machine base is 150 mm.
Preferably, the number of the reinforcing blocks is two.
Compared with the prior art, the beneficial effects of the utility model are that: connect at the top of scale bar through rotatory hand wheel, rotatory hand wheel clockwise rotation a week scale rises 0.01mm, rotatory hand wheel anticlockwise rotation a week scale descends 0.01mm, along with rotatory hand wheel anticlockwise rotation contact head will be surveyed the block rubber and flatten to the fixed station plane on, avoid the higher actual height of measurement height of block rubber to be greatly high, improve the measurement accuracy of block rubber.
