Fig. 2 is a cross-sectional view along AA in fig. 1.

In the figure: 1. the positioning device comprises a base plate, 2, a positioning coordinate, 3, a first positioning pin, 4, a second positioning pin, 5, a spiral spring, 6, a third positioning pin, 7, a handle, 8 and parts.

Detailed Description

The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in the figure, the utility model discloses a measuring device of part, including the anchor clamps of clamping part and the three-dimensional measuring machine (not shown) of measurement part size, anchor clamps include bottom plate 1, be provided with location coordinate 2 on the bottom plate 1, still be provided with a plurality of measuring area on the bottom plate 1, be provided with two at least first locating pins 3 in the measuring area, still be provided with second locating pin 4 in the measuring area, be provided with the recess in the second locating pin 4, install coil spring 5 in the recess.

Furthermore, a third positioning pin 6 is provided in the measuring region. The part 8 to be detected can be positioned through the third positioning pin 6, and the position of the part 8 to be detected is prevented from being reversed.

Further, the height of the third positioning pin 6 is smaller than the height of the first positioning pin 3.

Furthermore, the measuring areas in the same horizontal direction are in one group, a plurality of groups of measuring areas are arranged on the plurality of bottom plates, and the distances between the measuring areas in the same group are the same, so that the positioning is convenient.

Furthermore, at least two first positioning pins 3 are vertically arranged, so that the X-axis direction and the Y-axis direction of the part to be detected 8 can be conveniently fixed.

Furthermore, the handles 7 are arranged on the two sides of the bottom plate 1, so that the lifting tool is convenient to take.
