Description

Technical Field

[0001] The utility model relates to the field of drive shafts, in particular to a high-efficiency drive shaft punching device. Background Art

[0002] The automobile drive shaft is also called the automobile transmission shaft. It is the shaft in the transmission shaft of the universal joint that can transmit power. It is a high-speed, low-support rotating body, so its dynamic balance is very important. Generally, the transmission shaft must undergo a dynamic balance test before leaving the factory and be adjusted on a balancing machine. For front-engine rear-wheel drive vehicles, it is the shaft that transmits the rotation of the transmission to the main reducer. Therefore, the automobile drive shaft is one of the important components in the automobile manufacturing process.

[0003] At present, the hole feature processing of the internal parts of the automobile drive shaft is usually completed by CNC machining centers with automated processing and high processing accuracy. However, there are still some unresolved problems in the current CNC machining centers and the punching jigs used. The main problem is that during the drilling process of the current CNC machining center, the internal coolant system sprays from top to bottom from the direction of the punching transmission spindle, and then cools the workpiece and the tool during the processing. However, with the changes in processing height and processing position, the coolant sprayed by the coolant system is easy to deviate, which causes high friction temperature at the processing point of the tool and the workpiece, reducing the service life of the tool and easily damaging the workpiece.

[0004] For example, in a patent for a drive shaft punching device for automobile processing and production (Announcement No.: CN114310378A), it includes a CNC machining center and a basic fixture. The basic fixture is sleeved on the CNC machining center. The inner side of the top and the middle top surface of the basic fixture are respectively provided with a set of clearance grooves and a drive shaft component that is movably connected. The cooling pipe assembly, spray valve pipe assembly, direction adjustment component, and transition pipe provided in the invention are assembled together to form a new cooling auxiliary structure on the top of the basic fixture. Compared with the traditional coolant system that sprays from top to bottom, the new cooling auxiliary structure can spray coolant from multiple directions and multiple angles to the drive shaft component to be punched and the tool used for punching in the CNC machining center, thereby achieving a highly targeted and high-precision cooling effect, and solving the problem of the coolant sprayed from the traditional coolant system being offset, causing high friction temperature at the tool and workpiece processing.

[0005] The above patent achieves a highly targeted and precise cooling effect through a cooling pipe assembly and a liquid spray valve pipe assembly. In daily use, the valve pipe sprays water, causing water to accumulate in the device, and the water is reused and exported without change, which wastes water resources and reduces the resource utilization rate of the device. Therefore, it is necessary to invent an efficient drive shaft punching device to solve the above problem. Utility Model Content
