Testing fixture for elbow

Abstract

The invention discloses a testing fixture for an elbow. The testing fixture comprises a cuboid metal base and a sliding table, a cylindrical boss is arranged at the end, away from the sliding table, of the base, a sliding rail is arranged between the boss and the sliding table, and a first electric push rod parallel to the upper surface of the base is arranged on the upper portion of the sliding table; the side wall of the boss is provided with three protruding blocks capable of stretching out and drawing back automatically to serve as clamping devices. By adopting the technical scheme, 90-degree elbows with different bottom apertures can be fixed through automatic extension and retraction of the lug on the side wall of the boss, when the sliding table returns to the original position, thelug is automatically retracted, the elbows can be easily taken down, and meanwhile, the elbows with different heights can be detected through extension and retraction of the second electric push rod;and the extension of the first electric push rod is matched with the movement of the sliding block on the sliding rail, so that the range of the detected length of the elbow straight pipe is expanded, the cost for purchasing different testing fixtures is reduced, and the working intensity of workers is also reduced through automatic control.

Description

technical field [0001] The invention belongs to the field of mechanical manufacturing, and more specifically, the invention relates to a checking fixture for elbows. Background technique [0002] The inspection tool is a special inspection equipment used to measure and evaluate the dimensional quality of the parts. On the part production site, the online inspection of the parts is realized through the inspection tool. , or measuring table, or caliper, or mandrel, plug piece, etc. to inspect the surface and surroundings of the part, or use inspection pins or visual inspection to visually inspect the holes of different properties on the part and the connection position between parts and parts , so as to ensure the rapid judgment of the quality status of parts during production. When designing the structure of modern gauges, it is also considered that it can be used as a measuring bracket. For the inspection fixtures of matching parts that have matching requirements such as f...

Problems solved by technology

[0003] With the advancement of science and technology, parts are constantly being improved in manufacturing and production, and after parts are improved, they need to be measured with gages, but the gages of existing parts are fixed on the gage base and cannot be disassembled and replaced. Each checking fixture has to be matched with a checking fixture base, resulting in high cost of the checking fixture, and there is no automatic control in the checking fixture, and the work intensity of the staff is high
