Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples.
As depicted in figs. 1 and 2, the Charpy key hole specimen break detection ruler of the utility model, including main scale 1, along main scale axial direction
Upper and lower ends in main scale same side are equipped with two axial rectangle terrace with edges 5 being arranged symmetrically, between two terrace with edges 5
The rectangle sliding slot 12 axially arranged is formed, is equipped with one logical ruler 3, in cunning in one end of sliding slot 12 in the sliding slot 12
For the other end of slot 12 equipped with one ruler 2 is stopped, the logical ruler 3 and only ruler 2 can be free to slide in sliding slot 12, lead to ruler 3 and stop
The head shape of ruler 2 is the V-arrangement or U-shaped to match with the notch geometry of impact specimen 11, logical ruler 3 herein and only ruler 2
Portion's shape is V-arrangement, and only the V-arrangement angle of ruler 2 is greater than the V-arrangement angle of logical ruler 3, lead to ruler 3 and only the head of ruler 2 respectively with main scale
1 both ends flush；The both ends of same terrace with edge 5 are respectively equipped with a reference graduation line 6 on main scale 1, on logical ruler 3 and only ruler 2 in
It is respectively equipped with a zero graduation line 7 at position corresponding with two reference graduation lines 6, in each on logical ruler 3 and only ruler 2
From 7 rear end of zero graduation line be also successively arranged a notch minimum-depth graduation mark 8 and notch depth capacity graduation mark 9 respectively.
As a preferred embodiment, one is equipped with for by logical ruler 3 and only ruler 2 to divide in the middle position of the main scale 1
Separate and come and be the rectangular boss 4 radially arranged relative to main scale 1, lead to ruler 3 and only the tail portion of ruler 2 respectively with the boss 4
It is close to two sides.
As another preferred embodiment, one is further respectively had on the lateral surface at 5 both ends of same terrace with edge on the main scale 1
Fixing screws 10 can be by logical ruler 3 and only ruler 2 is fixed in sliding slot 12 when the fixing screws 10 are screwed, to save
The testing result of detection ruler.
The detection application method of the utility model Charpy key hole specimen break detection ruler is as follows:
By taking Charpy V-arrangement impact specimen as an example, the size of qualified impact specimen is 10 × 10 × 55mm, and V-notch angle is
45 ± 2 °, V-notch depth is 2 ± 0.075mm, and V-notch root radius is 0.25 ± 0.025mm；Charpy key hole specimen break inspection
The logical ruler V-arrangement angle of measurement ruler is 43 °, top radius 0.225mm, and only ruler V-arrangement angle is 47 °, and top radius is
0.275mm。
Firstly, clearing up the impact specimen to be detected processed, degrease, the foreign matters such as iron filings, burr, it is then right
Impact specimen detection ruler carries out school zero, and confirmation main scale reference graduation line can be with logical ruler and only ruler zero graduation line is overlapped, to guarantee
Impact specimen V-notch to be detected opening face is bonded by detection accuracy with main scale end face later, and promotion stops ruler V-arrangement head and inserts
Enter and is measured in impact specimen V-notch to be detected；If only contacting indentations bottom at the top of ruler, and there are gaps for fitting, that is, lack
47 ° of bicker degree >, then detect Charpy key hole specimen break off-dimension, and Charpy key hole specimen break is bigger than normal；If only contacting notch at the top of ruler
Bottom, and it is bonded closed seamless gap, i.e. Notch angle=47 °, but indicate the reference graduation line of notch depth in notch minimum-depth
Except graduation mark and notch depth capacity graduation mark range, i.e., notch depth is unqualified, then detects Charpy key hole specimen break size not
Qualification, Charpy key hole specimen break depth are bigger than normal/less than normal；If only contacting indentations bottom at the top of ruler, and it is bonded closed seamless gap, i.e. notch
Angle=47 °, while indicating that the reference graduation line of notch depth is carved in notch minimum-depth graduation mark (containing) and notch depth capacity
It spends between line (containing), i.e., notch depth is qualified, then detects Charpy key hole specimen break size qualification；If only notch cannot be contacted at the top of ruler
Bottom, i.e. 47 ° of Notch angle <, then use logical ruler instead and measure；At this point, if contacting indentations bottom, i.e. notch angle at the top of logical ruler
>=43 ° of degree, and indicate the reference graduation line of notch depth in notch minimum-depth graduation mark (containing) and notch depth capacity scale
Line (contains) between range, i.e., notch depth is qualified, then detects Charpy key hole specimen break size qualification；If contacting notch bottom at the top of logical ruler
Portion, i.e. Notch angle >=43 °, and indicate that the reference graduation line of notch depth is maximum deep in notch minimum-depth graduation mark and notch
It spends except graduation mark range, i.e., notch depth is unqualified, then detects Charpy key hole specimen break off-dimension, and Charpy key hole specimen break is deep
It spends bigger than normal/less than normal；If indentations bottom, i.e. 43 ° of Notch angle < cannot be contacted at the top of logical ruler, then Charpy key hole specimen break size is detected
Unqualified, Charpy key hole specimen break angle is less than normal.
Charpy key hole specimen break is detected using the utility model Charpy key hole specimen break detection ruler, testing result is shown in Table
1:
Table 1
By the above detecting step, can quickly and accurately judge to detect whether Charpy key hole specimen break processing meets standard
It is required that reservation is fixed to measurement result in the screw that can be tightened when needing fixed reservation testing result.
In conclusion the Charpy key hole specimen break detection ruler of the utility model convenient, fast, accurately can either try impact
Sample notch size and precision are detected, and directly can carry out detection use, and the letter of its structure in impact specimen processing site
