Automatic detection device for M-value of worm and runout of tooth surface

An automatic detection device and worm technology, applied in the direction of measuring device, mechanical measuring device, using mechanical device, etc., can solve the problem that the M value of the worm and the runout of the tooth surface cannot be judged as a whole, whether the worm curve is consistent, and the accuracy of the M value measurement cannot be judged. To avoid the risk of manual error and missed detection, the structure and setting method are novel, and the measurement force is small.

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.

Embodiment

[0025] Such as figure 1 The automatic detection device for the M value and tooth surface runout of the worm shown includes a worktable 2 on which a clamping unit for clamping the worm and a measuring unit for measuring the worm M value and tooth surface runout are provided, The measurement unit includes a contact part, a measurement part, a mobile base and a measurement control part. The contact part is connected to the measurement part. The measurement part is arranged on the mobile base 35. The measurement control part is connected to the mobile base 35. The measurement control part can control the measurement part and the contact. The part moves in the direction parallel to the clamping axis of the worm 1 and the radial direction of the worm, so that the contact part is in contact with the worm tooth surface for measurement.

[0026] This embodiment aims to measure the M value and tooth surface runout of the worm 1 by flexibly controlling the movement of the measuring part and ...

Abstract

The invention belongs to the technical field of detection devices, and discloses an automatic detection device for an M-value of a worm and the runout of a tooth surface. The automatic detection device comprises a workbench, wherein the workbench is provided with a clamping unit used for clamping the worm and a measuring unit used for measuring the M-value of the worm and the runout of the tooth surface, the measuring unit comprises a contact portion, a measurement portion, a moving base and a measurement control portion, the contact portion is connected with the measurement portion, the measurement portion is arranged on the moving base, the measurement control portion is connected with the moving base, and the measurement control portion can control the measurement portion and the contact portion to move along a direction parallel to a clamping axis of the worm and a radial direction of the worm so as to enable the contact portion to be contacted with the tooth surface of the worm toperform measurement. The automatic detection device abandons a method of manually detecting the M-value, and improves the detection accuracy through refined component setting. Meanwhile, the automatic detection device is mechanically operated in the whole process, can realize full detection for the M-value of the worm, avoids the risk of manual wrong detection and missed detection and improves the detection efficiency at the same time.

Description

Technical field [0001] The present invention relates to the technical field of detection devices, in particular to an automatic detection device for the M value and tooth surface runout of a worm. 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 distance between the rods), which is measured manually by using a common normal micrometer or a micrometer with a measuring rod. During the specific operation, the measuring rod cannot be fixed on the worm tooth. Therefore, in the process of micrometer measurement, 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 is also possible to apply a small amount of butter on the measuring rod to make it fit the worm. The method in the tooth groove, but this is equivalent to the introduction of impurities in the w...
