Specific embodiment
Principle of the invention and feature are described below in conjunction with accompanying drawing, example is served only for explaining the present invention, and
It is non-for limiting the scope of the present invention.
It is a kind of check metalwork linear dimension scope device, as shown in Figures 1 to 5, including proof-reading block 4, reference block 3,
Cubing plate 1, chaining pin 2, light emitting diode 6, battery 5 and resistance 7, the proof-reading block 4 be located at the reference block 3 top, and with
The reference block 3 is connected, the cubing plate 1 be located at the proof-reading block 4 top, and one end of the cubing plate 1 following table
Face is fitted on the upper surface of the proof-reading block 4, and the center of the cubing plate 1 is provided with a tapped through hole 9, and the chaining pin 2 passes through
Its afterbody is connected through the tapped through hole 9 with the cubing plate 1；The positive pole of the light emitting diode 6 passes through wire and institute
The positive pole for stating battery 5 is connected, and its negative pole is connected by wire with one end of the resistance 7, and the other end of the resistance 7 passes through
Wire is connected with one end of metalwork 8, and the other end of the metalwork 8 is connected with the negative pole of the battery 5, the cubing
The lower surface of plate 1 is fitted with the measurement datum on the metalwork 8.
The height dimension of the reference block 3 is identical with the minimum dimension of the linear dimension of the metalwork 8, the reference block 3
Height sum with the proof-reading block 4 is identical with the full-size of the linear dimension of the metalwork 8.
The cubing plate 1 is insulator, and its shape is plate-like.
In hemispherical, its afterbody is in stud shape to the head of the chaining pin 2, and the afterbody of the chaining pin 2 external screw thread size
Matched (see Fig. 2, afterbody is represented at A, head is represented at B) with the dimension of inner screw thread of the tapped through hole on the cubing plate 1.
Operation principle of the invention is as follows：
When using：
1) as shown in Figure 2 and Figure 3, reference block 3 is placed on levelling bench.The lower surface of cubing plate 1 is upper with reference block 3
Fit on surface.Rotation chaining pin 2 is until top and the upper surface of levelling bench of chaining pin 2.The other end and metalwork of battery 5
8 conductings.The lower surface of cubing plate 1 is fitted with the measurement datum on metalwork 8.If light emitting diode 6 does not light, metalwork
8 actual linear dimension meets the minimum dimension requirement of linear dimension；If light emitting diode 6 lights, the actual line of metalwork 8
Shape size is unsatisfactory for the minimum dimension requirement of linear dimension less than the minimum dimension requirement of linear dimension.
If light emitting diode 6 lights, show that the sphere on chaining pin top is contacted with the measuring surface of metalwork 8, circuit is led
Logical, i.e. the measuring surface of metalwork 8 is also smaller than desired minimum dimension with the distance between the measurement datum of metalwork 8, is discontented with
Sufficient minimum dimension requirement；If light emitting diode 6 does not light, the sphere and the measuring surface of metalwork 8 for showing chaining pin top do not have
Contact, circuit is off, i.e. the distance between the measuring surface of metalwork 8 and measurement datum of metalwork 8 ratio is required
Minimum dimension it is big, meet minimum dimension requirement.
2) as shown in Figure 4, Figure 5, proof-reading block 4 is placed in the top of reference block 3.The lower surface of cubing plate 1 and proof-reading block 4
Fit upper surface.Rotation chaining pin 2 is until top and the upper surface of levelling bench of chaining pin 2.The other end and metal of battery 5
Part 8 is turned on.The lower surface of cubing plate 1 is fitted with the measurement datum on metalwork 8.If light emitting diode 6 lights, metalwork
8 actual linear dimension meets the full-size requirement of linear dimension；If light emitting diode 6 does not light, the reality of metalwork 8
Linear dimension is unsatisfactory for the full-size requirement of linear dimension more than the full-size requirement of linear dimension.
If light emitting diode 6 lights, show that the sphere on chaining pin top is contacted with the measuring surface of metalwork 8, circuit is led
Logical, i.e. the measuring surface of metalwork 8 is smaller than desired full-size with the distance between the measurement datum of metalwork 8, meets most
Large scale requirement；If light emitting diode 6 does not light, the sphere and the measuring surface of metalwork 8 for showing chaining pin top are not in contact with,
Circuit is off, i.e., the maximum that the distance between measurement datum of the measuring surface of metalwork 8 and metalwork 8 ratio is required
Size is big, is unsatisfactory for full-size requirement.
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all it is of the invention spirit and
Within principle, any modification, equivalent substitution and improvements made etc. should be included within the scope of the present invention.
