Abstract
The invention belongs to a measuring method, in particular to an error online measuring method of a cam contour. The error online measuring method is characterized in that a measuring head is arrangedon a guide rail of a sand wheel frame through a measuring head seat; the vertical surface of the measuring head leans closely against the outer surface of a cam to be measured; the guide rail of thesand wheel frame is provided with a grating scale; the measuring head is provided with a position measuring device; a cam shaft is provided with an encoder; the cam shaft is rotated and the guide railof the sand wheel frame is moved synchronously so as to lead the rotation of the cam shaft and the movement of the guide rail of the sand wheel frame to conform to a rotating angle-lift curve of thecam, drive the measuring head seat to move horizontally, and measure the position size of the sand wheel frame displayed by the grating rule of the guide rail of the sand wheel frame when the cam is positioned at all angles and the position size displayed by the position measuring device on the measuring head, the two position sizes are added to obtain the practical rotating angle-lift curve of the cam; and compared with the required rotating angle-lift curve, the contour lift error at all angles of the cam can be calculated. The error online measuring method has simple method, convenient measurement and good economy and is scientific and reasonable.
Description
Technical field
The invention belongs to the measuring method class, specifically is a kind of error online measuring method of cam contour.
Background technology
In mechanical drive, usually use cam, but because the cam ground difficulty of processing is bigger, necessary on-line measurement error, the digital control system that makes lathe are processed higher precision according to measurement result correction data program thereby reach cam contour.The THE CAM PROFILE ERROR measuring essence is that cam is when all angles, vertical with surface level and draw error amount with position and desired corner-lifting curve contrast on the tangent plane of cam, during separately with measuring head traverse measurement lift, the measuring head stroke must be greater than cam lift, when cam lift is big, as big stroke more than the 100mm, measuring head is just very complicated, cause this square law device complex structure, involve great expense, failure rate is higher in the use.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, the error online measuring method of simple, easy to use, the scientific and reasonable cam contour of a kind of method that adopts mobile grinding carriage guide rail is provided.
Technical scheme of the present invention is as follows:
A kind of error online measuring method of cam contour, it is characterized in that: measuring head is installed on the grinding carriage guide rail by measuring headstock, the vertical plane of measuring head is near cam outer face to be measured, the grating chi is housed on the grinding carriage guide rail, position-measurement device is housed on the measuring head, scrambler is housed on the camshaft, the rotating cam axle, and with moved further grinding carriage guide rail, make the camshaft rotation move the corner-lifting curve that meets cam with the grinding carriage guide rail, driving the measurement headstock moves horizontally, measure the cam position dimension that position-measurement device shows on grinding carriage position dimension that the grinding carriage guide rail grating chi on all angles shows and measuring head, and, can draw the cam angle-lifting curve of reality both additions, compare with the corner-lifting curve that requires, can calculate the profile lift range error of cam in all angles.
The present invention adopts moving of grinding carriage guide rail, makes big stroke motion with the grinding carriage guide rail, only needs the measurement of micromovements head just can accurately measure the lift range error of cam contour, and method is simple, and it is convenient, scientific and reasonable to measure, good economy performance.
