Thread detection device of a nut thread inspection machine

Abstract

The invention discloses a thread inspecting device of a nut thread inspecting machine. The thread inspecting device comprises a machine frame, a motor, a work station switching plate and a swinging shaft, wherein the swinging shaft is rotationally installed on the machine frame, the work station switching plate and the swinging shaft are fixedly connected, and the work station switching plate is driven by a swinging power device; a feeding cylinder installed on the work station switching plate in an axial sliding manner, wherein the a material returning power device is fixed in an internal embedded hole of the feeding cylinder; an axial feeding power device, wherein the axial feeding power device is fixed to the work station switching plate and connected with the feeding cylinder, and the axial feeding power device drives the feeding cylinder to move in the axial direction; and an initial position detection sensor and a final position detection sensor which are fixed on the machine frame, the initial position detection sensor is corresponding to the head position of an inspected thread, and the final position detection sensor is corresponding to the tail position of the inspected thread. The thread inspecting device is capable of automatically inspecting nuts, so that a manual hand-held nut inspection mode is replaced, and the inspection efficiency and the accuracy of the inspection result are improved.

Description

technical field [0001] The invention relates to a thread detection device, in particular to a thread detection device of a nut thread inspection machine. Background technique [0002] The thread processing of the nut needs to be inspected. The nut with qualified thread rotates very smoothly when it is matched with the screw, and the nut with qualified thread will be jammed when it is matched with the screw, which will affect its qualified use. , and currently there is no equipment for automatic inspection of the threads of the threads. Usually, it is necessary to hold the nut and place it on the screw rod, and use the operator to feel whether the cooperation between the nut and the screw rod is smooth, so as to check whether the thread of the nut is good or not. However, there are many disadvantages in this backward detection method: 1. Since the nut is manually inspected by hand, judging whether the thread is good or bad is also manually judged. 2. Due to manual operation,...

[0002] The thread processing of the nut needs to be inspected. The nut with qualified thread rotates very smoothly when it is matched with the screw, and the nut with qualified thread will be jammed when it is matched with the screw, which will affect its qualified use. , and currently there is no equipment for automatic inspection of threaded threads. Usually, it is necessary to hold the nut and place it on the screw rod, and use the operator to feel whether the cooperation between the nut and the screw rod is smooth, so as to inspect the thread quality of the nut.

However, this backward detection method has many disadvantages: 1. Since it is manual hand-held nut detection, at the same time, judging whether the thread is good or bad is also a manual judgment. Therefore, the requirements for workers' skills are relatively high, and veterans with certain experience are required to complete

2. Due to manual operation, the efficiency of inspection is very low

3. Hand-held, there is a certain risk; 4. The test results are not necessarily accurate
