Nut thread inspecting machine

Abstract

The invention discloses a nut thread inspecting machine. The nut thread inspecting machine comprises a machine frame, an inspecting motor fixed on the machine frame, an automatic feeding device installed on the machine frame, a work station switching plate and a swinging shaft, an axial feeding power device, an initial position detection sensor and a final position detection sensor which are fixed on the machine frame, and a discharged material collecting device, wherein an output shaft of the inspecting motor is provided with an inspected thread; the swinging shaft is rotationally installed on the machine frame, a feeding cylinder is installed on the work station switching plate in an axial sliding manner, 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; the axial feeding power device is connected with the feeding cylinder; the initial position detection sensor is corresponding to the head position of the inspected thread, and the final position detection sensor is corresponding to the tail position of the inspected thread; and the discharged material collecting device is used for collecting nuts. The inspecting machine is capable of realizing automatic feeding, inspection and discharging of nut threads, so that the inspecting efficiency is greatly improved, and the accuracy of the inspecting result is improved.

Description

technical field [0001] The invention relates to an inspection device, in particular to 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, the efficiency of inspection is v...

[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
