Screw thread automatic detecting equipment and method

Abstract

The invention relates to screw thread automatic detecting equipment and a method thereof; the main frame of the equipment is a fixing frame, a screw thread detecting pin is driven by a working air cylinder fixed at the center of the outer part of the top side to move downwards to carry out detection, a product detecting fixture is arranged on a base of the fixing frame, and the position of a screw thread hole of the product to be detected is arranged right below the screw thread detecting pin; a sensor is arranged at one side of the screw thread detecting pin, the front end part of the sensor is vertical to the screw thread detecting pin and is arranged at a distance from the screw thread detecting pin, the sensor is triggered to carry out detection by the insertion of a screw thread detecting rod at the front end of the screw thread detecting pin or by different working states generated by preventing from moving downwards. The equipment fully utilizes the difference of pore diameter of an extruding and tapping product before tapping and after tapping to carry out judgment and identification, and full-inspection identification and marking are automatically carried out by the equipment, thereby being beneficial to realizing assembly line work, avoiding changing or lagging the production flow, reducing the risk on producing defective products in the process and having remarkable economic benefit.

Description

technical field [0001] The invention relates to the field of production automation equipment, in particular to thread automatic detection equipment. Background technique [0002] In industries such as home appliances and automobiles, since the extruded threads on sheet metal products can be directly used for the assembly of parts, the method of extruding and then tapping is widely used on sheet metal parts for this type of thread processing. This requires manufacturers of extruded thread products to ensure that no missed tapping occurs on the product, so as not to stop the assembly line and cause serious economic losses. Therefore, in the process of extruding threads, the method of checking and marking all the threads will be added to reduce the occurrence of missing threads. At present, most manufacturers adopt the method of manual full inspection and marking of inspection marks. On the one hand, due to the heavy and monotonous workload, especially when there are many thr...

AI Technical Summary

Problems solved by technology

On the one hand, due to the heavy and monotonous workload, especially when there are many threads on the product, all inspectors are prone to visual fatigue after long-term work, and the risk of misjudgment and missed judgment is high, and there is still a high risk of unqualified products flowing out. Big risk; on the other hand, the efficiency of manual full inspection is low, and the labor intensity of workers is high, so it is difficult to realize the automation and high efficiency of assembly line production
