Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to weapon equipment technical field, and specifically apply to a kind of hammer proofing for hammer size detection. BACKGROUND
[0002] Hammer is a new part of 40Cr material, there are two symmetrical conical surfaces in middle position, the distance of one of the conical surfaces to hammer head is key size, and the angle of the conical surface is one of the reasons affecting the distance size, so the conical surface angle also needs to be considered when detecting distance, and the measurement accuracy of ordinary proofing for the key size of hammer is not high, which can easily lead to deviation, thereby causing significant impact on later assembly and use. SUMMARY
[0003] The utility model discloses to solve the defects and deficiencies existing in the prior art, and provide a kind of hammer proofing with simple structure, easy operation, and high stability of inspection.
[0004] The technical scheme of the utility model discloses a kind of hammer proofing, including proofing body and mandrel, proofing body is equipped with the detection channel and mandrel channel that are perpendicular and intersect each other, the end face of the detection end of detection channel is divided into two detection end faces at detection hole, and the distance of the two detection end faces to the other end face of detection channel is different;When detecting, hammer is located in detection channel, and mandrel is located in mandrel channel, when the first conical surface on hammer is tightly attached to mandrel at channel intersection, hammer is detected end between the two detection end faces of proofing body and is qualified.
[0005] Further, the two detection end faces of the proofing body are symmetrically distributed along the center line of the detection hole.
[0006] Further, the proofing body is a cube or a cuboid.
[0007] Further, the mandrel is also provided with a shoulder.
[0008] Further, the proofing body and the mandrel are made of carbon steel.

[0014] The utility model will be described in further detail below in connection with the drawings, but is not limited to the scope of protection of the utility model.
[0015] Example one,
[0016] A hammer gauge, comprising a gauge body 1 and a mandrel 3, the gauge body 1 is provided with a detection channel and a mandrel channel which are perpendicular to each other and intersect, the end face of the detection end of the detection channel is divided into two detection end faces at the detection hole, and the distance of the two detection end faces to the other end face of the detection channel is different.
[0017] When the hammer 2 detection is carried out, first, the hammer 2 is inserted into the detection channel, then the mandrel 3 is inserted into the mandrel channel, the hammer 2 is adjusted until the first conical surface 4 on the hammer 2 is tightly attached to the mandrel 3 at the intersection of the channel, then the hammer 2 is observed to be detected, when the detection end of the hammer 2 is between the detection end face one 501 and the detection end face two 502 of the gauge body 1, it is qualified, and when the detection end face of the hammer 2 exceeds or does not enter between the two detection end faces, it is unqualified.
[0018] In the embodiment, the distance difference of the detection end face one and the detection end face two to the other end face of the detection channel is 0.08cm, as shown in the enlarged view. Figure 3 In the enlarged view.
[0019] Further, the two detection end faces of the gauge body 1 are symmetrically distributed along the center line of the detection hole.
[0020] Further, the shape of the gauge body 1 is a cube or a cuboid.
[0021] Further, the mandrel 3 is also provided with a shaft shoulder, which is used for axial positioning when the mandrel 3 is inserted.
[0022] Further, the material of the gauge body 1 and the mandrel 3 is carbon steel.
