Description
Technical field
The present invention relates to the gauge of machine components and methods, and in particular to the top surface of measurement part of the end face with inclined-plane
The measurer and method of length.
Background technique
It is shown in Figure 1, there are a kind of part 7 of the end face with inclined-plane, the ontology 7-1 of the part 7 in some special machines
The upper end of left side be inclined-plane M, the upper end of right side is inner concave K, and the formation angle of chamfer between inclined-plane M and top surface J is α
The end face length L of 0, top surface J are a significant dimensions.End face length L have defined standard value and permission maximum value and
Minimum value, and its allow maximum value and minimum value respectively the difference between standard value be end face length L standard value most grand duke
Difference and minimal tolerance value.As long as end face length L is equal to the maximum value and minimum value of defined standard value and permission, or is advising
Fixed standard value adds between maximum allowance value and defined standard value subtracts between minimal tolerance value, then end face length L is closed
Lattice.Since end face length L is the inner concave K of the inclined-plane M of the upper end of the left side of the ontology 7-1 of part 7 and the upper end of right side
The distance between top, i.e., be inclined-plane M, another side be on one side inner concave K.Thus, general measurer cannot be long to the top surface
Degree L is measured, and can only be measured using three coordinate measurement machines, the problems of be；Part 7 must be turned from lathe
It transports on three coordinate machine, if off-dimension, also by part 7, clamping is processed on lathe again.It is thus typically necessary to
Repeatedly measurement, repeatedly processing, just can determine that end face length L whether be equal to as defined in standard value or whether in maximum value or
Within the scope of minimum value, i.e., whether qualified, measurement efficiency and processing efficiency are lower.
Summary of the invention
Accurate, the higher measurement end face band inclined-plane part of efficiency that the technical problem to be solved in the present invention is to provide a kind of measurements
End face length measurer.
In order to solve the above technical problems, the present invention measures the measurer of the end face length of part of the end face with inclined-plane, including base
Quasi- plate, side plate, collet, screw, dial gauge and check gauge, it is characterized in that:

The measuring head of dial gauge 5 is resisted against on the inclined-plane M of part 7, and records the reading on dial gauge 5, then with the reading divided by base
The cosine value of first measurement angle α of quasi- plate 1 is compared with the maximum allowance value of the end face length L of part 7 and minimal tolerance value,
When the cosine value that the reading measures angle α divided by the first of datum plate 1 is greater than the maximum allowance value of the end face length L of part 7, part
It is unqualified, it is also necessary to continue to process；When the cosine value that the reading measures angle α divided by the first of datum plate 1 is equal to the top surface of part 7
The maximum allowance value or minimal tolerance value of length L, part is qualified, when the reading is divided by the cosine of the first measurement angle α of datum plate 1
For value between the maximum allowance value and minimal tolerance value of the end face length L of part 7, part is qualified；When the reading is divided by datum plate 1
First measurement angle α cosine value be less than part 7 end face length L minimal tolerance value, part is unqualified, scraps.Thus may be used
Know, the present invention can detect the end face length L of part 7 on lathe, detect processing more convenient and that make part 7 and
Qualification rate is higher.
Preferably, the collet 3 is made of spring steel.This enable its be open position 3-1 extended distance preferably
It reduces or becomes larger.
Preferably, the value of interference fit of the collet 3 and the location hole 2-3 on side plate 2 are 0~0.03mm.This to press from both sides
