Abstract

(57) [Summary] [Purpose] Directly and easily measure the dross after cutting a metal plate. A block having a hole perpendicular to a wall surface in which a large-diameter hole having at least one surface open and a small-diameter hole are connected in two stages, and which can be operated from the outside and hits the small-diameter hole at a right angle There is.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an instrument for measuring the height of dross generated by cutting a metal plate with heat or laser.

[0002]

[Prior Art]

 The dross generated by cutting the metal plate with heat or laser is used to judge the quality of the cutting. In particular, the height of the dross is convenient and frequently used to determine the amount of dross generated. Conventionally, the dross height had to be cut into a size such that the portion of the metal plate containing the dross to be measured could be placed on the dross height measuring instrument. In addition, the non-contact height measuring device by focusing is often used as the measuring method, and the accuracy is low.

[0003]

[Problems to be solved by the device]

 An object of the present invention is to provide a simple method for solving the above-mentioned drawbacks and directly measuring the dross height.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention is a block having a hole having a large diameter and a hole having a small diameter, at least one side of which is open, connected in two steps and having a hole perpendicular to the wall surface. The feature is that there is a holding screw that can be operated from the outside that hits at a right angle.

[0005]

[Action]

 The dial gauge auxiliary jig used in the present invention is generally made of metal, but hard plastic can be used. Also, the size can be appropriately adjusted according to the object to be measured.

[0006]

【Example】

 FIG. 1 is a schematic view showing an embodiment of the present invention. Inside the block 1, there are a vertical small diameter hole 2 and a large diameter hole 3 connected to it, and one side surface of the large diameter hole is open and can be seen from the outside. The probe protection tube of the dial gauge is inserted in the small hole 2. The stylus protection tube is fixed with a cap screw 4. In order to measure the cutting dross of the metal plate, the wall surface 5 of the block 1 may be brought into contact with the direction of the metal plate 6 after cutting, and a stylus may be applied to the tip of the dross 7 while visually observing from the side surface. In addition, it is necessary to contact the stylus on a suitable flat plate in advance and set the scale at this time to zero.

[0007]

[Effect of the device]

 By carrying out the present invention, the dross after cutting the metal plate can be easily measured directly.
