Abstract
The utility model relates to a grating displacement measuring device, and belongs to a displacement measuring instrument. The grating displacement measuring device comprises a grating sensor, and a spline guide rail. The spline guide rail is provided with a straight groove along an axial direction. The grating sensor comprises a metal grating ruler and a grating reading head. The metal grating ruler is struck on the straight groove. The grating reading head is fixed on a sliding sleeve of the spline guide rail. Movement distances of the sliding sleeve along the spline guide rail are accurately measured by the grating sensor. Since the spline guide rail has certain bending strength, other functional components can be installed on the sliding sleeve, thereby realizing measuring specific positions or control operation.
Description
Technical field
The utility model relates to grating displacement measuring device, belongs to displacement measuring instrument.
Background technology
Grating has obtained in fields such as exact instrument, coordinate measuring machine, high precision Precision Machining using widely as a kind of instrument of precision measurement.For wide range, high-precision position, displacement detection system, generally adopt double-frequency laser method and grating measuring technology at present in the world.On precision, the dual-frequency laser measurement method is better than grating measuring; But dual-frequency laser measurement installation cost height, technical sophistication, relatively harsher to the environmental requirement of using.And grating measuring can both satisfy high-precision requirement under most of occasions, add its good reliability, range is big, simple in structure, cost is relatively low, to series of advantages such as environmental requirement are tight, anti-interference is good, thereby in precision measurement and machine tool industry, be widely used.Grating measuring requires grating chi and read head to install respectively on the parts that move with a pair of opposing parallel, in machine tool industry, the grating measuring device volume is bigger, the grating chi is installed on the other pedestal of guide rail, read head is installed on the parts that move along guide rail, moving-member can carry other parts of constant weight, and the relative position of guide rail and pedestal is hard and fast; In precision measurement, grating displacement measuring device often is designed to integrated form, and volume is little, and on the installation of grating chi and the moving-member, read head is installed on the fixed part, and moving-member can not carry weight.
Summary of the invention
The purpose of this utility model is to provide a kind of can carry constant weight, grating displacement measuring device that volume is little
Technical solution
The utility model comprises grating sensor, spline guide rail, and the spline guide rail has groove vertically, and grating sensor is made up of metal grating chi, grating reading head, and the metal grating chi is pasted on the groove, and grating reading head is fixed on the spline guide rail slip cap.
The utility model metal grating chi is pasted in the groove, and grating reading head is fixed on the slip cap of spline guide rail, and slip cap can accurately be recorded by grating sensor along the distance that the spline guide rail moves.Because the spline guide rail has certain flexural strength, so on the slip cap other functional part can be installed, realize ad-hoc location is measured or control operation, satisfied the little grating measuring demand that can carry constant weight again of volume.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
The utility model comprises grating sensor, spline guide rail 2, bar-shaped trough left vertically by spline guide rail 2, grating sensor is made up of metal grating chi 1, grating reading head 3, and metal grating chi 1 is pasted on the bar-shaped trough, and grating reading head 3 is fixed on the spline guide rail slip cap 4.
During work, slip cap 4 moves along spline guide rail 2, and read head 3 reads the position signalling of metal grating chi 1, realizes accurately measuring.
