Description of the drawings
Fig. 1 is the structure diagram of the part tool for detecting surface profile of the prior art.
Fig. 2 is a kind of structure diagram of part tool for detecting surface profile of the utility model.
Specific embodiment
Referring to Fig. 1, the inventor of the utility model is in order to preferably managing the technical solution of the utility model
Solution, is described in detail below by specifically embodiment, and with reference to attached drawing：
Referring to Fig. 1, a kind of part tool for detecting surface profile of the utility model, including bearing 1 and test pin 3, branch
Seat 1 sets that there are one horizontal test pin through holes 11.
The radially inner side of test pin through hole 11 is coaxially provided with test pin guide sleeve 2, and the rear end of test pin guide sleeve 2 is one and branch
The annular table 21 of seat 1 rear end face fitting, the rear end face of annular table 21, the i.e. rear end face of test pin guide sleeve 2 are determined for test pin guide sleeve
Plane 22.Test pin 3 is in the radially inner side of test pin guide sleeve 2 and 2 slide fit of test pin guide sleeve；The front end of test pin 3 is equipped with can be with
The test pin confined planes 32 of the contoured surface fitting of part 9 to be detected.
It is recessed that position annular corresponding with 22 positions of test pin guide sleeve positioning surface is additionally provided on the outer circle wall of test pin 3
Slot 33, the width of annular groove 33 are equal with the width of the surface profile tolerance range of the contoured surface of part 9 to be detected.
For the ease of observation, pigment is scribbled in annular groove 33.The purpose for setting annular groove 33 is prevented because detection
The friction of pin 3 and test pin guide sleeve 2 and pigment is erased.What the rear end of test pin guide sleeve 2 was bonded for one with 1 rear end face of bearing
The purpose of annular table 21 is convenient for the position of observation annular groove 33.
In the present embodiment, the width of annular groove 33 is 2.0mm；The depth 0.3mm of annular groove 33.
When promoting test pin 3, so that the test pin confined planes 32 is bonded with the contoured surface of part 9, theoretically test pin guide sleeve
Positioning surface 22 should be corresponding with the midpoint of 33 width of annular groove, i.e. 22 zero set of test pin guide sleeve positioning surface.
When detecting part 9, relative position that can be between visual detection pin guide sleeve positioning surface 22 and annular groove 33, if ring
Connected in star 33 has all deflected away from detection guide sleeve positioning surface 22, i.e., observes along detection guide sleeve positioning surface 22, see completely straight down
It does not detect annular groove 33 or has observed complete annular groove 33, represent the surface profile of part allows beyond tolerance
Scope.Only observe straight down when along detection guide sleeve positioning surface 22 and observed the annular groove 33 of part, part 9
Surface profile be only it is qualified.
Since the part tool for detecting surface profile is detecting annular groove 33 and detection guide sleeve positioning surface 22 by visual observation
Between relative position when need to face, can not squint, otherwise detection can the larger of error in order to avoid error, can use and test pin
The sensor that guide sleeve positioning surface 22 is correspondingly arranged is visual to replace, and test pin is observed along the direction of test pin guide sleeve positioning surface 22
Position relationship on 3 between annular groove 33 and test pin guide sleeve positioning surface 22, according to the variation of color or sensor and inspection
The variation of distance between survey pin 3, judges relative position relation between annular groove 33 and detection guide sleeve positioning surface 22.
Test pin confined planes 32 are dismountable with test pin 3, and test pin 3 can detect the position degree in hole on part 9.
A kind of part tool for detecting surface profile of the utility model is also provided with go-no go gauge, to carry out surface profile detection
As a result phase mutual induction card.
The rear end of test pin 3 is equipped with handle 34, to control the patch between the contoured surface of test pin confined planes 32 and part 9
It closes.
The spring 35 being socketed with simultaneously on test pin 3 between handle 34 and annular groove 33.
A kind of advantage of part tool for detecting surface profile of the utility model is mainly reflected in：Measurement efficiency is high, can be with
Part surface profile is quickly judged, the part for being suitble to face tolerance bigger is easy to detect, beneficial to operation, without resolution
The size of go-no go gauge or clearance ruler, it is quick to measure, it is suitble to small lot and the measurement of large batch of full inspection.
Those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate that this practicality is new
Type, and be not used as the restriction to the utility model, as long as in the spirit of the utility model, to implementing above
Variation, the modification of example will all fall in the Claims scope of the utility model.
