Abstract
The invention discloses an inner chamfer detection device and method, and belongs to the technical field of detection. The inner chamfer detection device comprises a handle. A measuring rod made of metallic tin is arranged on the handle. The measuring rod is inserted into the sunken portion of a part to be detected and attached to an inner chamfer. The inner chamfer detection method comprises the following steps of firstly fixing the part to be detected, inserting the measuring rod made of the metallic tin into the sunken portion of the part to be detected so that the front end of the measuring rod can be pressed to form an outer chamfer consistent with the inner chamfer, pulling out the measuring rod, using a fillet gauge for detecting the outer chamfer formed at the front end of the measuring rod, judging whether relative reading is within the allowable tolerance range of the size of the inner chamfer or not, and continuously and circularly conducting rapid detection on the inner chamfer of a next part to be detected. Compared with the prior art, the front end of the measuring rod is pressed to form the outer chamfer consistent with the inner chamfer, the outer chamfer is directly measured, limitation caused by aperture changes does not exist, and meanwhile the inner chamfer detection device has the advantages of being simple in structure, convenient to use and operate, free of space limitation and the like.
Description
Technical field
The invention belongs to detection technique field, relate in particular to a kind of interior chamfer detecting device and detection method.
Background technology
In mechanical processing industry, be seen everywhere for the chamfering in hole, one utilizes slide calliper rule or projector to detect the depth of chamfering in hole, but slide calliper rule cannot correctly be positioned the inclined-plane of chamfering, cause testing result inaccurate, shadow instrument is subject to space constraint, in narrow space, cannot detect.The problems referred to above, urgently to be resolved hurrily.
Summary of the invention
The present invention is directed to deficiency of the prior art, a kind of interior chamfer detecting device and detection method are provided.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals: chamfer detecting device in a kind of, comprise handle, on described handle, be provided with the cylindrical measurement bar of being made by metallic tin, described sounding rod be inserted in the depressed part of part to be detected and with interior chamfering laminating; Also comprise fillet gage.Above-mentioned interior chamfering comprises interior bevelling and interior rounding.
In order to obtain better technique effect, further technological improvement is, the depth value of described sounding rod is greater than the depth value of the depressed part of described part to be detected.
Chamfering detection method in a kind of, comprises the steps: 1) first part to be detected is fixed; 2) hand holds handle, is inserted into the cylindrical measurement bar of being made up of metallic tin in the depressed part of part to be detected, makes the front end of sounding rod be pressed into the outer chamfering that interior chamfering is consistent; 3) extract sounding rod, detect the outer chamfering of sounding rod front end formation with fillet gage, whether read fortune falls in interior chamfer dimesion Measurement Allowance reading; 4) continue circulation the interior chamfering of next one part to be detected is carried out to fast detecting.
The invention has the beneficial effects as follows: the present invention adopts under normal temperature quality softer, fusing point is lower, the metallic tin that plasticity is strong is used as sounding rod, be inserted in the depressed part of part to be detected, make the front end of sounding rod be pressed into the outer chamfering that interior chamfering is consistent, and then the outer chamfering of the front end of directly measuring sounding rod, can not be subject to the restriction of varying aperture, have simultaneously simple in structure, use easy to operate, be not subject to the features such as space constraint, cost of manufacture are low.
Brief description of the drawings
