Description

Technical Field

[0001] The utility model relates to the field of positioning tools, and more specifically, to a perpendicularity inspection tooling. Background Art

[0002] In sheet metal processing, for a workpiece as shown in Figure 1 , it includes a main board, with a first positioning shaft and a second positioning shaft vertically arranged at one end of the main board. The first positioning shaft has a through hole, and a bending part is arranged in the middle of the main board. The drawing requires that the perpendicularity error between the first positioning shaft and the second positioning shaft is very small. Therefore, after welding the first positioning shaft and the second positioning shaft to the main board, it is necessary to inspect the perpendicularity of the two shafts. Simply relying on manual use of a caliper to inspect whether the first positioning shaft and the second positioning shaft are perpendicular to the main board is inaccurate, and a single positioning shaft needs to be measured and inspected multiple times, resulting in low inspection efficiency. In view of the above problems, it is urgent to design a set of tooling that can quickly and accurately inspect the perpendicularity of the workpiece. Summary of the Utility Model

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a perpendicularity inspection tooling, aiming to improve the problem of how to quickly and accurately detect the perpendicularity of a workpiece.

[0004] The utility model is realized as follows: A perpendicularity inspection tooling includes two symmetrically arranged positioning blocks and a pin shaft. A gap is reserved between the two positioning blocks. Each positioning block includes a main body in the middle and an extension rod arranged around the main body. The main body is columnar, with a 1 / 4 notch opened on the main body. A sink is opened at the central position of the main body. A pin hole penetrating through both ends is opened at the bottom of the sink. An annular groove is opened around the sink on the main body. The pin shaft passes through the pin hole. Two opposite sinks form a cylindrical cavity, and two opposite annular grooves form a rotation channel.

[0005] Further, strip-shaped notches are opened on the end faces of the extension rods of the two positioning blocks close to each other, and two symmetric strip-shaped notches form a rectangular channel.

[0006] Further, a threaded hole is opened at the end of the extension rod far from the main body.

[0007] Further, a gasket is arranged between the two positioning blocks at the position of the end of the extension rod.

[0008] Further, the distance between the two positioning blocks is 2 mm.

[0009] Further, the extension rod includes three, which are respectively arranged around the main body at equal intervals.

[0010] The beneficial effects of the utility model are:

[0011] The verticality inspection tooling of the utility model has a simple structure, reasonable and ingenious design, and includes two symmetrically arranged positioning blocks and a pin shaft. A gap is reserved between the two positioning blocks. The positioning block includes a main body in the middle and an extension rod arranged around the main body. The main body is columnar, with a 1 / 4 notch opened on the main body, a counterbore opened at the center position of the main body, a pin shaft hole penetrating through both ends opened at the bottom of the counterbore, and an annular groove opened around the counterbore on the main body.
