Specific embodiment
With reference to Figure of description, the present invention is further elaborated.
A kind of detection method of annular tongue-and-groove working face size of the present invention is comprised the following steps：
According to tenon groove structure feature and working face size (as shown in Fig. 3 A, 3B), the minimum dimension sample of design tongue-and-groove working face 4
Plate, meets tongue-and-groove turnery processing minimum dimension；
In Vehicle Processing tongue-and-groove, when the close minimum dimension of processing dimension, being checked whether with minimum dimension model to pass through
Annular tongue-and-groove working face；
If model passes through, clearance gauge is added at measuring basis, as shown in Figure 1；
If added clearance gauge is smaller in size than equal to maximum H that should add clearance gauge thickness, tongue-and-groove working face and gyroaxis line angle
Spend for α when, H=δ/2 × tg α, δ is tolerance dimension, and tongue-and-groove working face size meets and requires.
If added clearance gauge thickness is more than H, illustrate that the tongue-and-groove is unqualified, dimension overproof；
If model cannot illustrate that tongue-and-groove working face does not also reach minimum dimension by tongue-and-groove working face, continue to process.
In the present invention, disk like members tenon groove structure schematic diagram is as shown in Fig. 3 A, 3B.
In Fig. 2A, 2B, KAmaxFor full-size of the annular tongue-and-groove in the margin of tolerance, KAminIt is annular tongue-and-groove in tolerance model
Interior minimum dimension is enclosed, δ is tolerance dimension.
As shown in Fig. 4 A, 4B, minimum dimension model has template head 1 and handle 2, and template head 1 is one by under handle 2
The projection of Fang Yanshen, the body shape of template head 1 and tongue-and-groove working face 4 coincide, handle 2 and the coupling part of template head 1
Both sides end face is measuring basis 3.In the present embodiment, sample sheet material is 20# steel；Turn blue；Carburizing depth 0.3-0.5mm；HRC58-
62。
The present embodiment is as a example by 45 °, as shown in Figure 2 B by tongue-and-groove working face and axis of rotation.
According to tenon groove structure feature and working face size, tongue-and-groove working face minimum dimension model is designed, meet tongue-and-groove turning
Processing minimum dimension.The template head 1 of minimum dimension model is generally the part-structure of the direct triangle of isosceles, isosceles direct three
Angular hypotenuse stretches out specified altitude, and the width and height of right angle rim portion match with tongue-and-groove working face appropriate section.
Right-angle side is symmetrically extended upwards in specified altitude position and is connected with handle 2.
Because model can only judge whether tongue-and-groove working face size meets minimum requirement, in order to measure working face size reality
Value, using the triangular relationship of 45 ° of working faces of tongue-and-groove, the clearance gauge between model benchmark and parts measurement benchmark, clearance gauge thickness
Should be less than being equal to 1/2 working face dimensional tolerance, meet tongue-and-groove turnery processing less than full-size tolerance, it is ensured that tongue-and-groove adds Chinese musical scale
It is very little to meet drawing requirement.
In disk like members annular tongue-and-groove process, using the detection method of the model+clearance gauge designed by the present invention, to tenon
Groove working face size is detected.Carry out item by item according to operating procedure, in Vehicle Processing tongue-and-groove, when processing dimension is close to minimum chi
When very little, model inspection is used, if model does not pass through, illustrate that working face does not also reach minimum dimension；When model passes through, survey is can be used on
Amount benchmark place plug clearance gauge, due to 45 ° of right-angle sides of triangle two of working face it is equal, therefore clearance gauge thickness answer≤1/2 dimensional tolerance for close
Lattice.When reality processing is detected, clearance gauge thickness generally selects the dimensional tolerances of ＜ 1/2, it is to avoid dimension overproof.
Detection method, can quickly realize the detection of working face size in tongue-and-groove processing, it is ensured that tongue-and-groove working face adds
Work dimensional requirement, the method is simple, and operator is easy to grasp, and can effectively improve tongue-and-groove processing, detection efficiency and reduce work
Dress up this.
