Technical Field
The present utility model relates to an object detecting device, and more particularly to an object detecting device for a screw thread rolling machine.
Background
When a general screw thread rolling machine is used for thread rolling forming of a processing object, a thread rolling channel formed between two thread rolling plates is mainly utilized, so that the processing object can sequentially enter the thread rolling channel and is acted by the thread rolling plates to form threads on the processing object; therefore, in terms of the success or failure of the conventional screw thread rolling machine, depending on whether the processed object can be accurately positioned into the thread rolling channel, for example, when the processed object enters the thread rolling channel to be shifted (such as a high-low level difference or skew), the molded tooth shape of the processed object is incorrect or damaged, so that the processed object becomes a defective product.
The traditional detection mode is characterized in that the quality inspection after manufacture is generally performed by adopting a small metering sampling inspection mode, after finished products formed by the screw thread rolling machine are collected through a small collecting barrel, a person samples whether defective products exist or not, if no defective products exist in the small collecting barrel, the small collecting barrel is poured into a large collecting barrel for collecting, whether defective products exist in the forming process or not can not be found in real time, the screw thread rolling machine can rapidly manufacture and form the tooth shapes of the processed objects, the tooth shapes can reach more than hundred per minute, therefore, when defective products exist, a certain quantity is generally accumulated, the waste of the manufacturing cost of the process is caused, the problem of overlarge post selection time and cost is also caused, even if no defective products exist in the sampling inspection process, all the formed processed objects are defective products, and the whole quality cannot be ensured because the processed objects are not obtained through screening inspection; in addition, if the quality of each processed object can be guaranteed when the defective products are screened by the screening machine one by one after the fact, the screening mode is adopted one by one, besides the increase of the cost of the whole equipment caused by the need of purchasing screening equipment, the excessive detection time consumption can be caused by the additional screening mode, the defects of production efficiency reduction and whole production cost improvement are overcome, and the defect is needed to be improved.
