Abstract

The utility model discloses a roller hardness monitoring point depth-scale; a main body of the depth-scale is of a rectangular main scale (1), wherein, one side of the main scale (1) is provided with scale marks, and the other side of the main scale (1) is provided with a comma-shaped auxiliary scale (2) that is movably connected with the main scale, and the connection point between the main scale (1) and the auxiliary scale (2) is arranged at the middle part of the auxiliary scale (2); one end of the auxiliary scale (2) is provided with a pointing end (21) that points to the scale, and the other end of the auxiliary scale (2) is provided with a measuring head (22) that is probed into a drop pit of the monitoring point. When in measurement, the main scale is horizontally arranged above the roller monitoring point, and the measuring head is arranged inside the drop pit, and the measuring head is slightly pressed by the thumb to reach the bottom of the pit, so that the precise depth value can be read from the main scale. The depth-scale is simple, convenient and flexible to use, and can precisely, rapidly and conveniently measure the depth of the drop pit of the roller hardness monitoring point.

Description

Roll hardness check point dipstick

Technical field

The utility model relates to a kind of special measurement utensil, especially a kind of dipstick that is used to measure the roll hardness check point degree of depth.

Background technology

In the roll stage and semi-finished product, need carry out hardness and detect, by the technology requirement, the pit of several dark 0.5-5mm that polish at detected position, and then detect hardness number accurately with sclerometer.When polishing check point in the past, the degree of depth of each pit varies with each individual by operator's eye estimate, and is deep mixed, and therefore same the detected hardness of roll is also inaccurate, inconsistent, influences the formulation of next step heat treatment parameter; Sometimes the check point degree of depth exceeds standard, and also can make the roll turning quantity not sufficient, causes inferior waste product, brings unnecessary loss to enterprise.

Summary of the invention

The purpose of this utility model is exactly in order to overcome the above problems, and a kind of roll hardness check point dipstick of the accurate measurement hardness check point degree of depth is provided.

The utility model roll hardness check point dipstick main body is a rectangle main scale, main scale one side has scale mark, the main scale opposite side is provided with the secondary chi of the comma shape that flexibly connects with it, the tie point of main scale and secondary chi is located at the middle part of secondary chi, secondary chi one end is made as the indication end, point to scale, the secondary chi other end is made as gauge head, probes into the check point pit.

During measurement, the main scale of dipstick is lain in roll check point top, gauge head is put in the pit, one pressed gauge head gently, touch the hole at the end with thumb, just can read accurate depth value from main scale, because main scale, secondary chi tie point are located at the middle part of secondary chi, utilize lever principle, when gauge head test 1mm, the 1mm scale mark place on the main scale is just pointed in the indication end, and the expression check point degree of depth is 1mm.This dipstick is simple to operate in use, and is convenient, flexible, has good readability and intuitive, can measure the degree of depth of roll hardness check point pit accurately, quickly and easily, obtain hardness number accurately, thereby correctly formulate the roll Technology for Heating Processing, guarantee roll quality; And can avoid crossing deeply because of check point and cause phenomenon residual, inferior, waste product, accuracy of detection can reach 0.5mm, guarantees accuracy and consistance that hardness detects, helps improving the quality of products.

Description of drawings

Fig. 1 is the utility model structural representation.

Embodiment

As shown in Figure 1, the utility model roll hardness check point dipstick comprises main scale 1 and secondary chi 2, main scale 1 is a rectangle corrosion resistant plate, one side of main scale 1 has the 0-5mm scale mark, the opposite side of main scale 1 is equipped with the secondary chi 2 of comma shape, 2 of main scale 1 and secondary chis are flexible connection, as secondary chi 2 being combined with main scale 1 usefulness rivet, riveting point 12 is located at the middle part of secondary chi 2, so secondary chi 2 just becomes an active lever, and secondary chi 2 one ends are indication end 21, points to main scale 1 scale, the other end of secondary chi 2 is a gauge head 22, can probe into the check point pit.This dipstick is simple to operate in use, only needs a hand, main scale 1 side on the check point, one presses gauge head 22 gently with thumb, touch cheat the end after, pick up main scale 1 and just can read accurate depth value from main scale 1, accuracy of detection can reach 0.5mm.

Claims

1, a kind of roll hardness check point dipstick, it is characterized in that: its main body is a rectangle main scale (1), main scale (1) one side has scale mark, main scale (1) opposite side is provided with the secondary chi (2) of the comma shape that flexibly connects with it, the tie point (12) of main scale (1) and secondary chi (2) is located at the middle part of secondary chi (2), and secondary chi (2) one ends are made as indication end (21), points to scale, secondary chi (2) other end is made as gauge head (22), probes into the check point pit.
