A device and method for detecting worm spanning rod distance with automatic deviation correction function

Abstract

A worm spanning rod distance detection device with automatic deviation correction function, comprising a base on which a first positioning component, a second positioning component and a measuring component are arranged; a setting between the first positioning component and the second positioning component There is a worm placement assembly; the first positioning assembly includes a side plate arranged on the base, one side of the side plate is provided with two movable first positioning seats, each of the first positioning seats is provided with The first positioning column is axially rotatable, and the end of the first positioning column is provided with a first positioning head. The invention provides a worm spanning distance detection device and method with automatic deviation correction function. The overall structure of the device is compact and the design is reasonable. Three detection heads are used to locate the worm, and the positioning accuracy is high. Convenient and high detection accuracy.

Description

technical field [0001] The invention belongs to the field of worm measuring equipment, and in particular relates to a worm spanning distance detection device and method with automatic deviation correction function. Background technique [0002] Worm is a kind of hardware that is widely used. It usually works in conjunction with worm gear. The worm gear and worm structure are often used to transmit motion and power between two staggered shafts. Similar to the shape of the screw. [0003] For worms used in precision occasions, whether the size and depth of the ring gear on the surface are in compliance with regulations has a great impact on the product quality of the worm. Therefore, the finished worm needs to be inspected on the surface of the ring gear before leaving the factory. The depth of the ring gear is detected, the gap between the ring gear is detected, the inclination of the ring gear is detected, and the bar distance is detected. Generally, during the detection p...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, there is still a lack of a better detection device for the span of the worm, which takes a long time to detect and the detection efficiency is low

Moreover, some current detection devices lack the deviation correction function, which will cause the inclination angle of the detection head to be inconsistent with that of the upper ring gear of the worm, so that when the detection head is inserted into the gap of the ring gear, it cannot be perfectly matched and inserted, and the insertion depth is inaccurate, resulting in detection Accuracy drops

In the prior art, there are also some technologies in which the detection head can be rotated at a certain angle for insertion detection, but the structural matching is poor, the friction is large, and the wear is serious after long-term use, which also affects the detection accuracy.
