Tool for Fast Detection of Worm Length

Abstract

The present invention discloses a tool for fast detection of worm length, the tool comprises a base and a cover mounted on the base. Inner side wall of the cover is in rotatory connection with a second rotary rod through a bearing seat, lower end of the second rotary rod is in fixed connection with a fixed seat, the worm is clamped inside the fixed seat by a clamping mechanism, a scale is fixedlyinstalled on inner side wall of the cover, an oil storage barrel is fixedly installed on inner side wall of the cover, the oil storage barrel is filled with lubricating oil, and an oil outlet pipe isinstalled at bottom of the oil storage barrel. The tool can take the lead in realizing demonstration of working state of the worm through cooperation of the clamping mechanism and a simulated workingmechanism, so that detecting personnels can directly observe smoothness and occlusion tightness of meshing transmission between worm wheels and the worm through naked eyes, thereby worms that are outof specification are removed, greatly improving quality of worms leaving factory, preventing defective products from flowing into the market, and improving market reputation for enterprises to a certain extent.

Description

technical field [0001] The invention relates to the technical field of detection tooling, in particular to a tool for quickly detecting the length of a worm. Background technique [0002] There are many forms of mechanical transmission, which can be mainly divided into two categories: 1. Friction transmission that transmits power and motion by friction between parts, including belt transmission, rope transmission and friction wheel transmission. Friction transmission is easy to realize stepless speed change, and most of them can adapt to transmission occasions with large shaft spacing. Overload slipping can also play a role in buffering and protecting the transmission device, but this kind of transmission generally cannot be used in high-power occasions, and accuracy cannot be guaranteed. transmission ratio. 2. The meshing transmission that transmits power or motion by the meshing of the active part and the driven part or by the meshing of the intermediate part, including g...

Problems solved by technology

[0005] The purpose of the present invention is to solve the shortcomings in the prior art, such as: the appearance, size, specifications, etc. of the worm are generally detected when leaving the factory, but simply observing the appearance of the worm cannot detect the external thread of the worm. Whether the worm-shaped protrusion conforms to the specification can be judged, and there is no effective reference comparison, so a quick detection tool for the length of the worm is proposed.
