Abstract

(57) [Summary] [Purpose] Accurately and quickly measure the groove depth of parts. [Structure] A base (3) in which the support (2) of the dial gauge (10) is processed into a curved surface or a V-shape on the lower part (6) of the base.
Through the hole (11) and fix the dial gauge (10) with the set screw (1). Use the space gauge corresponding to the depth of the groove to set the measured value, and then use the dial gauge (15).
Swing back and forth to read the deflection of the pointer.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a dial depth gauge for measuring the depth of a groove or the like formed in a component.

[0002]

[Prior art]

 When the part to be measured is mounted on the machine tool, the lower part of the dial depth gauge is flat, which is inconvenient because the measurement is done while constantly adhering to the part. Therefore, it was inefficient because of the inconvenience of having to measure while moving the whole body each time to change the position of the eyes.

[0003]

[Problems to be solved by the device]

 Since the parts to be measured and the lower part of the dial depth gauge are measured in close contact with each other on a flat surface, if foreign matter is mixed in or if the lower part of the base is inclined and not in close contact, accurate measurement cannot be performed. Atsuta

[Means for Solving the Problems]

 In order to quickly and easily measure the depth of the parts mounted on the machine tool, the shape of the lower part of the base is curved so that the contact condition with the lower part of the base is not a flat surface but a line even in a narrow depth. Alternatively, it was formed in a V shape.

[0005]

[Action]

 Prepare two space gauges corresponding to the measurement depth on the surface plate. Place the bottom of the base on it. Pass the bail of the dial gauge through the hole in the base, and fix the dial gauge with the set screw so that the pointer of the dial gauge corresponding to the measurement depth becomes 0 at the position where the measuring terminal touches the surface plate. If the measurement depth and the height of the space gauge are different, turn the adjustment dial and set with the dial fixing screw. Next, when the dial depth gauge is inserted into the groove to be measured and swung back and forth as shown in Fig. 3, when the pointer of the dial gauge swings and it matches the scale 0, it is found that the finish is the standard size. Also, when finished to a size other than the standard size, the depth of the part can be measured from the difference between the scale and the zero point when the deflection of the pointer is minimized.

【Example】

 Examples will be described with reference to the drawings. FIG. 1 is a side view of the present invention. The support brace 2 of the dial gauge 10 is passed through the hole 11 of the base 3, and the dial depth gauge 15 set to the measurement dimension is set by the set screw 1, the adjusting dial 8 and the dial fixing set screw 7 into the groove 14 of the component 13. Shows the ability to be plugged into. The measuring terminal 5 is in contact with the bottom of the groove 14 and the lower part 6 of the base is in contact with the upper part of the component 13. The lower part 6 of the base is curved. The lower part 6 of the base may be V-shaped, but it is not shown. This figure shows an example in which the base 3 is processed from a round bar, and this method is convenient when the base lower part 6 is curved. It is important to use a wear resistant material for the base 3 and to accurately finish the squareness between the hole 11 and the base lower portion 6.

FIG. 2 shows a measuring method. When the dial depth gauge 15 is swung back and forth as shown in the figure, the pointer 4 of the dial gauge 10 swings, and when the scale matches 0, it is found that the reference dimension is finished. If the scale does not match zero, reading the minimum scale will measure the increase or decrease from the nominal size.

FIG. 3 is a front view of the dial depth gauge 15 and shows a method of setting measurement values. Two space gauges 9 corresponding to the measurement depth are placed on the surface plate 12 for preparation. Place the lower part 6 of the base on it.

Next, as described above, when the pointer 4 is adjusted to the scale 0 with the adjusting dial 8 of the set screw 1 and the dial fixing set screw 7, the measurement preparation of the groove having the same depth as the space gauge 9 is prepared. Is completed. When the depth of the groove 14 is different from that of the space gauge 9, the scale may be increased or decreased by the adjustment dial gauge 8 and set by the dial gauge fixing screw 7.
