Automatic detection device for worm m value and tooth surface runout

Abstract

The invention belongs to the technical field of detection devices, and discloses an automatic detection device for the M value of a worm and the runout of a tooth surface. A beating measuring unit, the measuring unit includes a contact part, a measuring part, a moving base and a measuring control part, the contact part is connected with the measuring part, the measuring part is arranged on the moving base, the measuring control part is connected with the moving base, and the measuring control part can be The measuring part and the contact part are controlled to move along the direction parallel to the clamping axis of the worm and the radial direction of the worm, so that the contact part is in contact with the tooth surface of the worm to measure. The invention abandons the method of manually detecting the M value, improves the detection accuracy by refining the setting of the parts, and at the same time, the whole mechanical operation can realize the full inspection of the M value of the worm, avoid the risk of manual error and missed detection, and at the same time improve the detection efficiency.

Description

technical field [0001] The invention relates to the technical field of detection devices, in particular, to an automatic detection device for the M value of a worm and the runout of a tooth surface. Background technique [0002] In the prior art, the detection of the M value of the worm relies on manual inspection (the M value is the value across the rod distance). Therefore, in the process of measuring the micrometer, it is necessary to take into account the two important issues of the stable placement of the measuring rod and the accurate measurement position of the micrometer, and the operation is complicated. The practice in the tooth slot, but this is equivalent to introducing impurities in the worm tooth slot, which will affect the measurement accuracy of the M value more or less. [0003] Furthermore, the manual measurement of the M value through the measuring rod and the micrometer is a point value, and it is impossible to judge whether the curve of the entire helic...

Problems solved by technology

[0002] In the prior art, the detection of the M value of the worm relies on manual inspection (M value is the value of the distance across the rod), and the measurement is performed manually with a common normal micrometer or a micrometer with a measuring rod. During the specific operation process, the measuring rod cannot be fixed on the worm gear. Therefore, in the process of measuring the micrometer, it is necessary to take into account the two important issues of stable placement of the measuring rod and accurate measurement position of the micrometer. The operation is complicated. Of course, it can also be achieved by applying a small amount of butter to the measuring rod. The practice in the tooth groove, but this is equivalent to introducing impurities into the tooth groove of the worm, which will more or less affect the accuracy of the M value measurement

[0003] Furthermore, the manual measurement of the M value with a measuring stick and a micrometer is a point value, and it is impossible to judge whether the curve of the entire helical groove surface of the worm is consistent. The operator's operation and measurement methods are different, which will cause a large risk of manual measurement errors, and the manual measurement speed is slow and the measurement repeatability is not high. It is impossible to judge the M value and tooth surface runout of the worm as a whole, and it is easy to bury quality hidden dangers.
