Description

Technical Field

[0001] This utility model belongs to the technical field of hardware processing, specifically relating to an automatic tapping machine. Background Technology

[0002] like Figure 1 As shown, workpiece 1 includes a main body, a first screw hole 101 and a second screw hole 102. The main body is shaped like the number 7 and includes a first surface 103 arranged horizontally and a second surface 104 arranged vertically. The first screw hole 101 is provided on the first surface 103 and there are four of them, which are arranged in pairs on both ends of the first surface 103. The second screw hole 102 is provided on the second surface 104 and there are two of them, which are respectively arranged on both ends of the second surface 104.

[0003] Conventional tapping processes typically employ tapping machines. Existing tapping machines often have only one set of tapping components and a relatively limited tapping feed direction, generally either vertical, horizontal, or inclined. Therefore, automatic tapping machines can only tap one plane of the workpiece, processing each threaded hole on that plane individually. The problem is that when tapping a workpiece with this structure, the operator must move the workpiece horizontally to tap the first threaded hole on the first surface, then flip and move the workpiece horizontally again to tap the second threaded hole on the second surface. This requires the tapping machine to repeat the tapping operation multiple times on the same workpiece, and moving or flipping the workpiece takes time to align the threaded holes, increasing processing time and resulting in low processing efficiency, thus impacting normal production.

[0004] Therefore, further improvements are needed. Utility Model Content
