Description

Vise for Vickers hardness tester {VISE FOR VICKERS HARDNESS TESTER}

The present invention relates to a vice for a Vickers hardness meter, and more specifically, to a vise for a Vickers hardness tester that can be easily fixed regardless of the shape error of the object to be measured.

The measuring principle of Vickers hardness is to apply a certain amount of force to a pyramid-shaped press to press the surface of the specimen, and then calculate the hardness by measuring the average diagonal length of the indentation (mark permanently pressed by the press) permanently left on the surface of the specimen. In other words, the hardness test method uses the phenomenon that when force is applied to a press to deform a material, large indentations appear in the case of soft materials and small indentations appear in the case of hard materials.

A first screw hole for screwing the screw 140 is formed in the first fixing tank 120.

Figures 7 and 8 are exploded perspective views of the moving tank of a Vickers hardness test vise according to an embodiment of the present invention.

The moving tank 200 is configured to move along the upper surface of the body 110 and fix the object to be measured (10).

The moving tank 200 includes a slider 210 and a tilt adjusting unit 220.

The slider 210 includes a bottom portion 211 and a pressing portion 212.

The bottom portion 211 is placed on the base 100 and a guide convex portion 211a is formed on the lower surface, and the guide convex portion 211a is inserted into the sliding groove 111 and guided along the sliding groove 111.

And the pressing portion 212 protrudes upward from one area of the upper surface of the bottom portion 211. A screw groove 212a is formed on one surface of the pressing portion 212. The screw 140 penetrates the first screw hole and is coupled to the screw groove 212a, and as the screw 140 rotates, the slider 210 advances and retreats along the sliding groove 111. And a pair of insertion holes 222 are formed on the other surface of the pressing portion 212.

The other upper surface area of the bottom portion 211, that is, the upper surface of the bottom portion 211 where the pressing portion 212 is not formed, consists of a seating surface 211b and an inclined surface 211c. The seating surface 211b is a flat surface formed at approximately the center of the upper surface area of the bottom portion 211, and the inclined surface 211c slopes downward from both ends of the seating surface 211b.

The tilt adjustment unit 220 is configured to firmly fix the object to be measured (10) despite the shape error of the object to be measured (10).

The tilt adjustment unit 220 is placed on the upper surface of the upper surface area of the bottom surface 211. More specifically, the tilt adjustment unit 220 is seated on the seating surface 211b.

A second screw hole 211d is formed in the bottom part 211, and a through hole 221 is formed in the tilt adjustment part 220 along the height direction so that the fixing screw 211e passes through the through hole 221. It is coupled to the second screw hole (211d). Here, the through hole 221 is provided larger than the fixing screw 211e to allow movement of the inclination adjustment unit 220, which will be described later.

One side of the tilt adjusting unit 220 is parallel to the second fixing tank 130 or the first fixing tank 120, and the other surface is inclined toward the virtual center line of the pressing unit 212 from both ends and protrudes. It is prepared as follows. In other words, the central part of the other surface of the tilt adjustment unit 220 is closest to the other surface of the pressing unit 212, and the degree of separation from the other surface of the pressing unit 212 increases as it moves toward both ends.

In addition, a pair of insertion holes 222 are formed on one surface of the tilt adjustment unit 220, that is, on the surface opposite to the pressing unit 212. That is, a pair of corresponding insertion holes 222 are formed on opposing surfaces of the pressing portion 212 and the tilt adjusting portion 220, and an elastic member (not shown) is inserted into each insertion hole 222.

Depending on the shape of one surface of the tilt adjusting unit 220, rotation of the tilt adjusting unit 220 is allowed. This rotation is allowed only until one surface of the tilt adjusting unit 220 contacts the other surface of the pressing unit 212.

Due to this rotation, the object to be measured (10) can be firmly fixed despite the shape error of the object to be measured (10). As the pressing part 212 moves, the tilt adjusting part 220 comes into close contact with the object to be measured (10). At this time, if the shape of the object to be measured (10) is not flat due to an error, etc., the object to be measured (10) is moved. ) The tilt adjustment unit 220 is rotated according to the shape.

When the tilt adjusting unit 220 does not rotate, the elastic member is in a restored state, and when the tilt adjusting unit 220 rotates in one direction, the elastic member in that direction is compressed and the elastic member in the opposite direction is stretched.

When the pressing part 212 is retracted and the tilt adjusting part 220 is not in contact with the object to be measured 10, the compressed/extended elastic members are restored and the tilt adjusting part 220 is returned to its original position.

Figure 9 is a coupling relationship diagram of the adjusting part of the Vickers hardness test vise according to an embodiment of the present invention.

The adjusting unit 300 is also configured to firmly fix the object to be measured (10) despite the shape error of the object to be measured (10).

A groove 131 having an arc-shaped cross section is formed on the inner surface of the above-described second fixing tank 130.

The adjusting part 300 is provided to have a curvature corresponding to the groove part 131 and is mounted in the groove part 131. At this time, the arc length of the adjusting part 300 is provided to be larger than the arc length of the groove part 131, so that the adjusting part 300 protrudes from the inner surface of the second fixing tank 130.

In this embodiment, the groove portion 131 and the adjusting portion 300 are magnetically coupled, and rotation of the groove portion 131 is allowed. The rotation of the groove portion 131 is linked to the tilt of the tilt adjusting portion 220.

Specifically, when the shape of the object to be measured 10 is not flat due to an error, etc., the pressing part 212 moves so that the tilt adjustment part 220 comes into close contact with the object to be measured 10, and the object to be measured ( The tilt adjustment unit 220 is tilted according to the shape of 10). At this time, the adjusting unit 300, which is in close contact with the opposite side of the measuring object 10, also rotates by the tilt adjusting part 220, so that the measuring object 10 is connected to the tilt adjusting unit 220 and the adjusting unit ( 300) and is firmly fixed between them.

From now on, the operation of the Vickers hardness meter vise according to an embodiment of the present invention will be described. For convenience of explanation, the shapes of the objects to be measured (10) are separately described. 10 to 12 are diagrams illustrating the operation of a Vickers hardness tester vise according to an embodiment of the present invention.

When there is no error in the shape of the object being measured

Referring to FIG. 10 , the object to be measured 10 is placed on the upper surface of the body 110 while the tilt adjusting unit 220 and the adjusting unit 300 are sufficiently spaced apart from each other. Afterwards, the screw 140 is rotated to move the slider 210 toward the adjusting unit 300.

As the slider 210 moves, the tilt adjusting unit 220 presses one side of the measuring object 10, causing the measuring object 10 to move toward the adjusting unit 300, and the measuring object 10 The tilt adjustment unit 220 presses the object to be measured 10 while being in close contact with the adjustment unit 300 on the other surface.

Through this, the object to be measured (10) is firmly fixed.

Object to be measured with a side that is not parallel to the other side of the tilt adjuster

Referring to FIG. 11 , the object to be measured 10 is placed on the upper surface of the body 110 while the tilt adjusting unit 220 and the adjusting unit 300 are sufficiently spaced apart from each other. Afterwards, the screw 140 is rotated to move the slider 210 toward the adjusting unit 300.

As the slider 210 moves, the tilt adjusting unit 220 presses one side of the measuring object 10, causing the measuring object 10 to move toward the adjusting unit 300, and the measuring object 10 It is in close contact with the control unit 300 on the other side.

However, due to the shape of the object to be measured 10, the side of the object to be measured 10 is not parallel to the other surface of the tilt adjusting unit 300, so the other surface of the tilt adjusting unit 220 and the object to be measured 10 A separation space is formed between them.

When the screw 140 is continuously rotated, while the other surface of the object to be measured 10 is in close contact with the adjuster 300, the tilt adjuster 220 rotates by the space separated from the object to be measured 10, thereby adjusting the tilt. The control unit 220 is also in close contact with the object to be measured (10).

At this time, the elastic member in the direction in which the tilt adjustment unit 220 is rotated is compressed, and the elastic member in the opposite direction is stretched.

If the pressing part 212 is retracted after measurement and the tilt adjusting part 220 is not in contact with the object 10 to be measured, the compressed/extended elastic members are restored and the tilt adjusting part 220 is returned to its original position.

An object to be measured that has an upper or lower surface that is not parallel to the body

Referring to FIG. 12 , the object to be measured 10 is placed on the upper surface of the body 110 while the tilt adjusting unit 220 and the adjusting unit 300 are sufficiently spaced apart from each other. Afterwards, the screw 140 is rotated to move the slider 210 toward the adjusting unit 300.

As the slider 210 moves, the tilt adjusting unit 220 presses one side of the measuring object 10, causing the measuring object 10 to move toward the adjusting unit 300, and the measuring object 10 It is in close contact with the control unit 300 on the other side.

However, the upper and/or lower surfaces of the object to be measured 10 are not parallel to the body 110, so a separation space is formed between the other surface of the tilt adjustment unit 300 and the object to be measured 10.

When the screw 140 is continuously rotated, the other surface of the object to be measured 10 is in close contact with the adjuster 300, and the tilt adjuster 220 is tilted by the space spaced apart from the object to be measured 10. The control unit 220 is also in close contact with the object to be measured (10).

At this time, the adjusting unit 300 rotates as much as the tilt adjusting unit 220 is tilted, so that the object to be measured 10 is firmly fixed as a whole.

According to the present invention, a vice for a Vickers hardness meter that can be easily fixed regardless of the shape error of the object to be measured is provided.
