Description

VERNIER CALIPERS HAVING A SUPPORT DEVICE

The present invention relates to a vernier caliper provided with an auxiliary device, and more particularly, to a vernier caliper provided with an auxiliary device configured to be usefully squeezed out according to the shape of the workpiece to be measured.

In general, the vernier caliper is a kind of field precision measuring instrument that can measure the length, thickness, diameter, and depth of the workpiece.The measuring method is that the jaws of the mother and the jaws of the slider adhere closely to both ends of the workpiece to measure the length or thickness. The length and thickness of the workpiece were measured using the main scale and the vernier scale.

However, such a vernier caliper, as shown in Figure 1, the projection 11 is formed on one side of the measurement object 10, the other side of the mother to measure the length of the measurement object 10 is stepped When the workpiece 10 is placed between the jaw 21a and the jaws 22a of the slider 22, either the jaws 21a of the mother 21 or the jaws 21a of the jaws 22a of the slider 22 are provided. ), (22) end is caught by the projection (11) of the measurement object 10, so that the other side jaw is in a free state does not touch the measurement object 10 by the step of the measurement object (10) There was a problem that can not measure the exact length or thickness of the desired portion of 10).

The present invention is limited in view of the above problems, the purpose of the vernier caliper is provided with an auxiliary mechanism configured to combine the auxiliary device according to the shape of the workpiece to be measured to quickly and accurately measure the measurement object Is to provide.

According to a feature of the present invention, in a conventional vernier caliper consisting of a jaw of a mother scale having a main scale and a jaw of a slider having a vernier scale, a bracket coupled to a jaw of the mother or a jaw of a slider is detached from the bracket. There is provided a vernier caliper with an auxiliary device comprising an auxiliary device.

Hereinafter, with reference to the accompanying drawings a vernier caliper provided with an auxiliary mechanism which is an embodiment of the present invention in detail as follows.

2 is a perspective view showing an embodiment of the present invention.

As shown, the vernier caliper provided with the auxiliary device 320 of the present invention has a jaw 210a of the mother 210 with an engraved main scale 211 and a jaw of a slider 220 engraved with a vernier scale 221. Each bracket 310 is coupled to a predetermined portion, and the auxiliary mechanism 320 is detachably coupled to the bracket 310.

The bracket 310 has a cross-section c-shaped guide groove 311 in the longitudinal direction on both sides of the connection frame 312 disposed perpendicular to the jaw 210a of the mother 210 or the jaw 220a of the slider 220. It is formed along, the stopper 313 is formed horizontally on the upper end of the connecting frame 312, the bracket 310 is a predetermined portion of the front surface of the bracket 310 or 210 (a) of the mother 210 The coupling hole 314 is formed so that the fastening member 318 detachably attached to the jaw 220a of the slider 220 is fastened.

Meanwhile, the bracket 310 may be integrally formed with the jaw 210a of the mother 210 or the jaw 220a of the slider 220 and may be integrally formed with a vernier caliper. The jaw 210a and the jaw 220a of the slider 220 may be installed in only one of the jaws.

The auxiliary mechanism 320 has a guide rail 322 having a guide protrusion 321 is inserted into the guide groove 311 of the bracket 310 on one side of the guide frame 328 having a predetermined length is sliding It is formed in the inner direction, a fixing hole 323 is formed in the predetermined portion of the other side of the guide frame 328 to penetrate into the guide rail 322 from the outside, the fixing member (323) 325 is fastened so that the auxiliary mechanism 320 coupled to the bracket 310 can be fixed.

On the other hand, by forming a plurality of fixing holes of the auxiliary device to which the fixing member 325 is fastened to be able to more firmly fix the auxiliary device coupled to the bracket, the auxiliary device 320 is the measurement of the object 100 It can be configured in various lengths and shapes according to the shape.

Such a method of using the vernier caliper provided with the auxiliary device of the present invention, as shown in FIG. 3, the auxiliary device 320, which is easy to measure the workpiece 100, has a pair 210a of the mother 210. B, after coupling to the bracket 310 coupled to the jaw 220a of the slider 220, tighten the fixing screw 325, and the auxiliary mechanism 320 is connected to the jaw 210a of the mother 210 to which the bracket 310 is coupled. It is to be integrated with the jaw 220a of the slider 220, and then the measurement object 100 is measured using the auxiliary mechanism 320 as a reference plane.

As described above, a bracket is coupled to a jaw of a mother or a jaw of a slider, and a vernier caliper having an auxiliary device configured to detachably couple an auxiliary device made to be easily measured according to the shape of a workpiece to the bracket. Thus, by allowing the measuring object formed with the step or the projection to be more quickly and accurately, there is an effect that can improve the efficiency of the field work.
