Background technologyIn field of machining, all has stepped hole on many components of machine, especially the stepped hole of axial workpiece is more common, the vehicle compressor axle is as axial workpiece commonly used, its stepped hole right alignment is the whether qualified and important indicator that affects product quality of check product, it is the problem that often runs in the surveying work that vehicle compressor axle right alignment detects, at present, the right alignment that is used for this axle stepped hole of check mainly adopts special-purpose surveying instrument, three-coordinates measuring machine for example, although three-dimensional coordinates measurement can be checked the right alignment of stepped hole more intuitively, still has the following disadvantages:
1, complicated operation, proving time is long, greatly affects production efficiency, increases production cost;
2, there is certain error in check, can not realize one hundred percent inspection at processing site, can not in time reflect product quality.
Summary of the inventionThe object of the present invention is to provide a kind of not only proving time short, simple to operate, reduce production costs, enhance productivity, and error is little, can realize one hundred percent inspection at processing site, can in time reflect the method that is used for check vehicle compressor axle stepped hole right alignment of product quality.
Particular content of the present invention is as follows:
The product that the present invention checks is existing vehicle compressor axle, has stepped hole radially on it, the upper end that is product has downward hand-hole, it is macropore, the lower end of product has hand-hole upwards, be aperture, the bottom of macropore has the hole that communicates with it, i.e. hole A, the bottom of hole A has the hole that is communicated with it, be hole B, the diameter of this hole B is less than the diameter of hole A, and the bottom of hole B has the hole that is communicated with it, be hole C, the diameter of this hole C is identical with the diameter of hole A, and the upper end of hole C is connected with hole B, and the lower end of hole C is connected with aperture.Require the right alignment of above-mentioned hole A and hole C less than 0.1mm, the method for inspection is as follows:
One, the instruments of inspection: comprise hole axle and axle, its mesopore axle is the diameter circular shaft identical with the hole A diameter of product, inwardly establishes the round slot bore identical with the hole B diameter of product along an axial end face of hole axle; Above-mentioned axle is comprised of coaxial two parts circular shaft, this two parts circular shaft is connected as a single entity, the diameter of its middle and upper part circular shaft is identical with the diameter of the hole A of product, the diameter of bottom circular shaft is identical with the hole B diameter of product, and the length of bottom circular shaft is more than or equal to the degree of depth of hole axle inner circular slotted eye, and the length of described bottom circular shaft is also more than or equal to the hole B of product and the total depth of hole C;
Two, check: axle is inserted in the A of hole by the large nose end of product, then the top circular shaft of axle is engaged in the hole A of product, the bottom circular shaft of axle passes the hole B of product, then the hole axle is inserted in the C of hole along the small bore end of product, can the round slot bore of inspection hole axle cooperate with the bottom circular shaft of axle, if the bottom circular shaft of axle can be inserted in the round slot bore of hole axle, judge that then product is qualified, after the insertion, the hole axle matches with the hole C of product, the round slot bore of hole axle matches with the bottom circular shaft of axle, and the top circular shaft of axle matches with the hole A of product; If the bottom circular shaft of axle can not the round slot bore of patchhole axle in, judge that then product is defective.
The present invention compared with prior art has following advantage:
1, verify error is little, and the time is short, enhances productivity;
2, simple to operate, reduce production costs, save duty cycle;
3, one hundred percent inspection can be realized at processing site, product quality can be reflected timely.
