Abstract
The invention relates to an automatic on-line detection method for dual measurement of a numerical control grinder. The method comprises the following steps of grinding the outer diameter of a bearing in a reciprocating manner on a numerical control vertical mill, according to the set grinding dimensions, in the grinding process, repeatedly recalling the measurement procedure of a measurement gauge I of measurement instruments, and measuring the grinding dimensions of grinding measuring points; after measurement is completed, recalling the measurement procedure of a measuring gauge II of the measurement instruments, and measuring dimension changes, caused by the temperature changes, of auxiliary measuring points; and according to the measuring results of the measuring gauge I and the measuring gauge II, recalling compensation dimension procedures, determining the next grinding quantity, and performing grinding and processing until the target dimension is obtained. According to the automatic on-line detection method disclosed by the invention, the dimension of products in the grinding process can be effectively and accurately controlled.
Description
Technical field
The invention belongs to and belong to numerically control grinder to bearing ring grinding manufacture field.Relate to numerically control grinder two measurement automatic on-line detection method.
Background technology
Conventional numerically control grinder is in grinding bearing lasso process, and on-line checkingi only detects grinding face, owing to producing thermal deformation in grinding, as easy as rolling off a logly occurs measure error, thus size is increased cause waste product or grinding size inadequate, be installed grinding again.In bearing products grinding (particularly extra large size bearing product), the grinding dimensional accuracy of variations in temperature to product is most important, as in external diameter (or internal diameter) operation grinding process, because emery wheel and lasso grinding produce heat, make the inside or outside dilatancy of lasso, usual on-line measurement only detects grinding side.Size=dilatancy amount+grinding the size of workpiece sensing, dilatancy amount is measure error.In order to obtain accurate dimension, after the complete workpiece of grinding needs insulation 8 hours, just grinding result can be measured, to determine being continue grinding, or overground or certified products.Variations in temperature is a great problem in grinding always, the serious crudy affecting product and working (machining) efficiency.
Summary of the invention
In order to ensure the defect that exists in the crudy of numerically control grinder in grinding bearing lasso process and on-line measurement work, the invention provides that a kind of numerically control grinder is two measures automatic on-line detection method,
Technical scheme of the present invention is: numerically control grinder is two measures automatic on-line detection method, realizes steps of the method are: (1) on numerical control vertical grinder with the external diameter of the reciprocal grinding bearing workpiece of emery wheel;
(2) according to the setting of grinding size, the process of measurement of the repeatedly chaining pin one of the amount of calling instrument in grinding process, measure the grinding size of grinding measurement point, after completing the measurement of grinding measurement point, the process of measurement of the chaining pin two of the amount of calling instrument, measures the change in size that subsidiary point causes due to the change of temperature;
(3) call free size program according to the measurement result of chaining pin one and chaining pin two, determine next stock removal, until be ground to target size, process qualified products.
The invention has the beneficial effects as follows, can effectively and accurately control the size of product in grinding process, improve grinding dimensional accuracy and the grinding efficiency of product.

Detailed description of the invention
The invention will be further described for composition graphs 1 and Fig. 2
Numerically control grinder is two measures automatic on-line detection method, and the implementation step of the method is:
(1) on numerical control vertical grinder, use the external diameter of the reciprocal grinding bearing workpiece 2 of emery wheel 1;
(2) according to the setting of grinding size, the process of measurement of the repeatedly chaining pin 1 of the amount of calling instrument 3 in grinding process, measure the grinding size in grinding measurement point A face, after completing the measurement in grinding measurement point A face, the process of measurement of the chaining pin 25 of the amount of calling instrument 3, measures the change in size that subsidiary point B face causes due to the change of temperature;
(3) call free size program according to the measurement result of chaining pin 1 and chaining pin 25, determine next stock removal, until be ground to target size.
In grinding bearing lasso process, adopt 2 on-line checkingi, except detecting grinding face, also will detect the opposite face (non-grinding face) of grinding face, in non-grinding face, detect thermal deformation, by the change of thermal deformation size, auto-compensation is in digital control system.In digital control system, establishment is two measures auto Detection Software, by the data analysis of two probe measurements and calculating, its result is incorporated in grinding program, thus controls the size of product in grinding process.Improve grinding dimensional accuracy and the grinding efficiency of product.
Claims (1)
1. numerically control grinder is two measures automatic on-line detection method, and it is characterized in that, the implementation step of the method is:
(1) on numerical control vertical grinder, use the external diameter of the reciprocal grinding bearing workpiece (2) of emery wheel (1);
