Specific implementation mode
The utility model is described in detail with reference to the accompanying drawings and detailed description.
A kind of guide rail linearity measuring system provided by the utility model, including Machinery Ministry and measurement portion two parts, such as Fig. 1
Shown in Fig. 2, Machinery Ministry includes the basic rack 2 parallel with tested guide rail 1, and moving assembly 3 is provided on basic rack 2, is moved
Dynamic component 3 is moved along basic rack 2, and measuring head base 4 is fixed on moving assembly 3, and measuring head base 4 has connection cross bar 5, connects cross bar
5 one end is located at the top of tested guide rail 1 as installation end；As shown in figure 3, measurement portion includes being set to connection cross bar 5 to install
Two displacement sensors 6 at A, two displacement sensors 6 are held to be each perpendicular to the setting of 1 surface of tested guide rail, two displacement sensings
Device 6 is connected with analog-digital converter 7 jointly, and analog-digital converter 7 is connected with processor 9 by data collecting card 8.
Preferably, measuring head base 4 is magnetic stand, is 3 correspondence of moving assembly metal, is being moved in this way convenient for measuring head base 4
The dismounting on dynamic 3 surface of component.
Specifically, moving assembly 3 is made of two mutually perpendicular planks, two planks respectively with basic rack 2 and its
Side wall tightly fits closely, and to move along a straight line when ensureing that moving assembly 3 drives measuring head base 4 to move, will not shift.
Example, two displacement sensors are all made of Bi1-5-EG08-LU type inductance type transducers, analog-digital converter
Model MAX196, the model PCL-816 of data collecting card.
Before measuring, moving assembly 3 be close to basic rack 2 and can along its linear movement, adjust two displacement sensors 6 it
Between spacing and ensure that the surface of itself and tested guide rail 1 is vertically arranged, i.e. be mutually parallel between two displacement sensors 6.Displacement
