[0018] The utility model discloses a kind of machining auxiliary positioning tools, datum block 2 inside is opened with a sliding slot that can make stand 1 only carry out linear motion, datum block 2 is sleeved on stand, then ruler 3 is inserted into the opening of recess one side opening in stand 1, installation of auxiliary tool can be completed.

[0019] The opening on the column 1 can make the scale move linearly inside, the tail end of the scale 3 is provided with a L-shaped limiting structure, so that the scale 3 is clamped after being inserted into the opening and cannot continue to move, the hook 5 is clamped in a row of clamping grooves on the scale 3, since the part of the hook 5 inserted into the clamping groove 4 is a vertical surface and an inclined surface, the inclined surface faces the insertion direction of the scale 3, and the vertical surface faces away from the insertion direction of the scale 3, so that the hook 5 can be rotated around the pin shaft when the scale 3 is inserted into the opening, when the next clamping groove moves to the lower side of the hook 5, the hook 5 is reset to be inserted into the clamping groove 4 under the pushing of the elastic element, and the surface of the clamping groove 4 facing the insertion direction is also a vertical surface, which cooperates with the hook 5 to limit the scale 3 from being withdrawn in the reverse direction, when the scale 3 needs to be withdrawn, the hook 5 can be pulled by inserting the fingers into the groove.

[0020] A right-angle notch is formed on one side of the reference block 2, the two surfaces of the reference block 2 in the right-angle notch are a horizontal reference surface and a vertical reference surface which are perpendicular to each other, the column is parallel to the vertical reference surface, and the scale 3 is parallel to the horizontal reference surface, after the blank is placed on the working surface, the notch of the reference block 2 is clamped on the upper surface and the side surface of the workbench, the column 1 drives the scale 3 to move up and down until the scale 3 falls on the upper surface of the blank, when the lower surface of the scale completely abuts against the blank, it indicates that the installation of the blank is accurate.

[0021] The scale 3 is processed with a scale, and the zero point of the scale is at the end away from the limiting structure, when the distance between the edge of the workpiece and the edge of the workbench needs to be measured, only the zero point end is contacted with the edge of the workpiece, the vertical surface of the reference block is contacted with the edge of the workbench, the uppermost edge of the reference block is on the same plane as the vertical reference surface, and only the reading of the uppermost edge is needed, when the hole depth of the surface of the workpiece needs to be measured, the scale is inserted for reading.
