Embodiment Construction

[0016] In specific implementation:

[0017] The first step is to make the cross arm 2 mainly composed of the measuring probe 1 , the fixed plate 3 , the driving screw 15 , the slide rail 17 , the motor 16 and the linear displacement sensor 20 .

[0018] The fixed plate 3 is located at one end of the cross arm and is made of steel, the basic shape is square, and the upper surface is stepped, such as Figure 5 As shown, there are slide rail mounting holes 34, slider mounting holes 35, folding plate mounting holes 36, motor mounting holes, and bearing mounting holes on the fixed plate 3. Fixed block 19 is positioned at cross arm other end, and is made of steel, and basic shape is cube, and the four jiaos of upper surface have the screw hole that bearing is installed, and side center has square through hole, and through hole size is identical with slide rail 17 profiles. On the fixed plate 3 and the fixed block 19, there are respectively screw-fixed bearings 11 in order to instal...

Abstract

In the present invention, products of sliding rail, linear displacement transducer, angular displacement transducer, transmission screw and motor on the market are used to assemble a three coordinate measuring instrument with cylindrical coordinate system. The instrument has three parts of cross arm, vertical arm and base for realizing movement of three-dimensional direction to achieve purpose of measuring workpieces in various outlines.

Description

(1) Technical field [0001] The invention relates to the technical field of measurement, in particular to a three-coordinate measuring instrument of a cylindrical coordinate system. (2) Background technology [0002] At present, the structure of the known three-coordinate measuring instrument of the cylindrical coordinate system consists of three parts: a cross arm, a vertical arm and a base. The vertical arm is cylindrical, and the lower end is fixedly installed on the base. There is a round hole at one end of the rectangular cross arm, through which the cross arm is set on the vertical arm, and can slide up and down along the vertical arm, and can also rotate around the vertical arm. The measuring probe is installed on the cross arm and can slide back and forth along the cross arm. The measuring probe slides along the transverse wall, and the transverse arm can rotate around the vertical arm while sliding along the vertical arm. Through the above-mentioned movement, the m...
