Automatic bolt testing machine

Abstract

The invention discloses an automatic bolt detection machine. The automatic bolt detection machine comprises a machine frame, a turntable workbench, a feeding mechanism, a height detection mechanism, athread detection mechanism and a discharging mechanism. The machine frame is provided with a feeding station, a height detection station, a height unqualified product outlet station, a thread detection station, a thread unqualified product outlet station and a qualified product outlet station along the circumference. The turntable workbench performs intermittent rotary movement and is installed in the centers of all stations of the machine frame, and multiple feeding gaps corresponding to all the stations are formed in the circumferential direction of the turntable workbench. The feeding mechanism is used for transporting a workpiece to be detected from a silo to the feeding station. The height detection mechanism is used for detecting the length of the workpiece to be detected. The thread detection mechanism is provided with a thread pass gauge and used for detecting whether a thread of the workpiece to be detected is qualified or not. The discharging mechanism is used for the smoothdischarge of the workpiece to be detected. The automatic bolt detection machine realizes the flow operation through the turntable workbench, sequentially performs height detection and thread detection on the workpiece to be detected, and has the advantages of high efficiency, low false detection rate and high automation degree.

Description

technical field [0001] The invention relates to the field of detection technology and equipment, in particular to an automatic detection machine for bolts. Background technique [0002] Non-standard parts with threaded parts need to be inspected after processing to see if they are qualified. The inspection items generally include size inspection, thread inspection, etc. as attached figure 1 For the valve bolt shown, the height and thread of the bolt need to be inspected, usually by means of a caliper and a thread gauge. If manual detection is adopted, it is not only inefficient, but also prone to false detection. The patent document of authorized notification number CN202284935U discloses a thread detection device for detecting the threaded part of a workpiece, which can automatically complete the detection of the thread, but it can only detect one workpiece at a time, and cannot realize assembly line operation, although It can reduce the workload of operators, but the ef...
