Abstract
Description
Technical Field
[0001] This utility model relates to the field of CNC machining technology, and in particular to an automatic feeding device for CNC machining of pipe fittings. Background Technology
[0002] In the CNC machining of pipe fittings, feeding is a key pre-process. Traditional feeding methods mostly rely on manual operation, where workers need to place the pipe fittings to be processed one by one into the feed port of the processing equipment. This is not only inefficient, but also labor-intensive and costly. Furthermore, manual feeding is prone to errors that can lead to inaccurate pipe fitting positioning, affecting processing accuracy. Although some companies have begun to try semi-automatic feeding equipment, existing equipment often suffers from complex structures, easy pipe fitting stacking and blockage, and feeding rhythm that is not matched with the processing equipment, making it difficult to meet the high-efficiency production needs of batch pipe fitting processing. Therefore, we propose an automatic feeding device for CNC machining of pipe fittings. Utility Model Content
[0003] To address the aforementioned problems, this utility model provides an automatic feeding device for CNC machining of pipe fittings. This utility model solves the problem that workers must place the pipe fittings to be processed one by one into the feed inlet of the processing equipment, which is not only inefficient but also labor-intensive and costly. Furthermore, manual feeding is prone to errors due to operational mistakes, leading to inaccurate pipe fitting positioning and affecting processing accuracy. Although some companies have begun to try semi-automatic feeding equipment, existing equipment often suffers from complex structures, easy pipe fitting stacking and blockage, and a feeding rhythm that is mismatched with the processing equipment, making it difficult to meet the high-efficiency production needs of batch pipe fitting processing.

[0010] The advantages and beneficial effects of this utility model are as follows: This utility model provides an automatic feeding device for CNC machining of pipe fittings. Through the transmission of the moving plate 10, the push plate 11 also moves accordingly. The push plate 11 pushes the pipe fittings inside the feeding trough 6. When the pipe fittings move above the guide plate 13, the pipe fittings roll onto the conveyor belt 5 through the guide plate 13. Through the mutual cooperation between the first drive shaft 3 and the second drive shaft 4, the conveyor belt 5 can transport the pipe fittings to be processed. The second motor 14 drives the shaft 15 to rotate. Through the transmission of the shaft 15, the unloading plate 16 also rotates accordingly. The pipe fittings move between the two unloading plates 16 through the conveyor belt 5. When the unloading plate 16 rotates, the automatic feeding of the pipe fittings can be completed. This type of feeding device has a simple structure. Through the cooperation of the first motor, the second motor and the hydraulic cylinder, it realizes the full automation of the pipe fitting from storage, transportation to pushing, without the need for manual intervention, which greatly improves the feeding efficiency. The design of the inclined feeding trough, partition plate, guide rod and protective plate effectively avoids the pipe fitting from stacking and blocking, shifting and falling, and ensures the stable feeding rhythm.
