Description

Technical Field

[0001] This utility model relates to the field of tapping machine technology, specifically to a tapping machine. Background Technology

[0002] A tapping machine is a machining equipment used to process internal threads in the holes of workpieces. It is widely used in industries such as machinery manufacturing, mold making, and automotive parts. Based on the driving method, it can be divided into manual, pneumatic, electric, and hydraulic tapping machines. Pneumatic tapping machines use compressed air as power and are characterized by their portability, high efficiency, and simple operation. Equipped with a precision torque collet, they prevent tap breakage and ensure a thread accuracy of grade 7. Electric tapping machines are driven by a motor, providing stable torque and rapid repeatability, suitable for machining threads from M3 to M24. The universal joint is a key component of the tapping machine, used to enable flexible rotation of the tapping machine spindle at multiple angles. Through a ball joint or cross-shaft structure, it allows the spindle to rotate freely within a certain angle range while maintaining continuous power transmission. The universal joint design allows the tapping machine to adapt to different tapping angle requirements, improving processing flexibility and efficiency. During the tapping process, the universal joint ensures the stability and accuracy of the tapping machine spindle, thereby guaranteeing the quality of the machined threads.

[0003] A search revealed that CN213795180U discloses a power head for drilling and tapping linkage, relating to automated machining equipment and hardware parts processing. It includes a tool assembly slide mounting block, a tool changing linear guide and slider, a tool changing mold side plate, a multi-axis gearbox, a first servo motor, a gearbox mounting back plate, a universal joint hexagonal sleeve, a gas-changing cylinder, an axial feed slide, a second servo motor, a ball screw, a screw nut, an axial feed module frame, a power head fixing plate, an axial feed linear guide and slider, a tool module block, a second tool, a first tool, a tool mounting output shaft, a hexagonal universal joint, a tool assembly slide, and a tool changing slide push plate. The tool changing linear guide and slider are connected below the tool assembly slide mounting block. The beneficial effects of this utility model are: the equipment adopts a method of fixing the workpiece, tooling, and machine head body while allowing the tool to move, increasing the practicality of the equipment.

[0004] The problem with the aforementioned power head that combines drilling and tapping is that:

[0005] 1. Insufficient rigidity of the tool changing mechanism: The pneumatic tool changer has limited positioning accuracy. In addition, the linear guide rail is prone to wear after long-term use, which affects stability. The tool changing process is prone to vibration, which affects machining accuracy.

[0006] Second: Limited accuracy of multi-axis synchronous control: There is a transmission gap between the output shafts of the multi-axis gearbox, making it difficult to accurately guarantee the synchronization of each tool axis. Torque fluctuations during tapping affect the thread quality. Utility Model Content
