Embodiment Construction

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0027] Such as figure 1 As shown, the present invention provides a technical solution: a regular octagonal cross-section pipe part position inspection tool, including a bottom plate 1 and an electrical indicating circuit 9, and the top of the bottom plate 1 is connected with an insulating Board 2, the material of insulating board 2 can be polytetrafluoroethylene etc., make insulation effect better, and the two first fastening screws 4 that connect on insulatin...

Abstract

The invention discloses a regular-octagonal cross section type tubular part position degree checking device, which comprises a bottom plate and an electrical indicating circuit, wherein the top part of the bottom plate is connected with an insulating plate through a first positioning pin, a first fastening screw connected on the insulating plate extends into a threaded hole formed in the bottom plate, the top part of the insulating plate is connected with a stop block through a second fastening screw, the insulating plate and the stop block are fixed via the second fastening screw, the stop block is electrically connected with the electrical indicating circuit, and the top part of the stop block is connected with a stop cover through a rectangular groove. The regular-octagonal cross section type tubular part position degree checking device greatly reduces the unnecessary reworking load, and decreases the maximum mistaken reworking load from 29.3% to 7.6%, namely, can reduce the mistaken reworking load by 73% at most, thereby improving labor productivity, reducing cost, and avoiding the problem that a slightly-collided measured tube body is not easy to find out when adopting the traditional method.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a regular octagonal cross-section pipe part position inspection tool. Background technique [0002] It is reported abroad that the pattern recognition of the camera system is used, and the direct detection of the application of the vision system is used. The price of this system is high. There are also systems that use sensor detection, but the price is still high. For products with small batches, it will be difficult to recover the investment cost of the detection system. At present, most domestic enterprises adopt the detection method of square cross-section go-gauge and stop-gauge. However, this method tightens the allowable tolerance zone, and as a result, some qualified products become (repairable) waste products, resulting in unnecessary rework and reducing enterprise productivity. And the square cross-section pipe inspection tool is a traditional method,...
