Embodiment 1

[0035] like Figure 1-4 As shown, the present embodiment provides a thread detection device, including a detection rod 1, an actuator 2 and a sound collection and analysis device 3, such as image 3 As shown, the front end of the probe rod 1 is provided with a probe 11, the probe 11 can be formed by protruding from the side of the end of the probe rod 1, or the front end of the probe rod 1 can be inclined to form the probe 11, and the probe 11 is used for connecting with the screw thread Abutment; the actuator 2 is connected with the detection rod 1, and is used to drive the detection rod 1 close to the thread to be detected, so that the probe 11 is in contact with one end of the thread, and drives the detection rod 1 to move along the length direction of the thread; sound collection and analysis device 3 is used to collect the sound generated when the detection rod 1 collides with the thread when it moves, and analyze the peak number of the sound signal corresponding to the s...

Embodiment 2

[0040] like Figure 5-Figure 6 As shown, the present embodiment provides a thread detection method, comprising the following steps:

[0041] S1: Extend the probe 1 into the thread to be tested, and abut the probe 11 on the probe 1 against the thread;

[0042] S2: The detection rod 1 sticks to the surface of the thread and moves from one end of the thread to the other end of the thread along the length of the thread;

[0043] S3: Collect the sound produced by the collision between the detection rod 1 and the thread during the moving process, and analyze the peak number of the sound signal corresponding to the sound.

[0044] When the probe 11 of the detection rod 1 moves from one end of the thread to be measured to the other end, it will collide and produce sound when it moves between two adjacent threads of the thread. By collecting the sound during the movement, and analyzing its corresponding The number of peaks of the acoustic wave signal can be used to obtain the number ...

Abstract

The invention discloses a thread detection device and method, relates to the technical field of thread detection, and is designed for detecting the number of threads. The thread detection device comprises a detection rod, an execution mechanism and a sound collection and analysis device, and a probe is arranged on the side face of the end of the detection rod in an outward protruding mode and abuts against the thread. The execution mechanism is connected with the detection rod and used for enabling the detection rod to be close to the to-be-detected thread, enabling the probe to abut against one end of the thread and driving the detection rod to move in the length direction of the thread. The sound collection and analysis device is used for collecting sound generated by collision between the detection rod and the threads when the detection rod moves and analyzing the number of peak values of sound signals corresponding to the sound. In the measurement process, the probe of the detection rod collides to generate sound when moving between two adjacent threads of the thread, the number of the threads of the detected thread can be obtained by collecting the sound and analyzing the number of the peak values of the sound wave signals corresponding to the sound, the structure is simple, the automation degree is high, and the detection efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of thread detection, in particular to a thread detection device and method. Background technique [0002] With the rapid development of industrial technology, the degree of automation of mechanical devices is getting higher and higher, and the requirements for the accuracy of workpieces in the manufacturing process are also getting higher and higher. It is necessary to test the quality of the produced workpieces to ensure the overall accuracy of mechanical devices. Require. [0003] At present, the traditional thread quality inspection methods mainly include thread ring gauge or plug gauge, thread micrometer measurement, tooth thickness vernier caliper measurement, three-needle measurement method, double-needle measurement method, etc. These measurement methods are slow in measurement speed and are not conducive to improving the assembly line. automatic detection speed. Contents of the invention [0004]...
