Description

Technical Field

[0001] This utility model relates to the field of machining center technology, and in particular to a four-axis swing mechanism for machining centers. Background Technology

[0002] In the existing technology, the machining center is a new type of CNC machine tool with a high level of automation and intelligence. It integrates multiple machining functions and, through pre-programmed CNC programs, the equipment can accurately control the relative movement between the tool and the workpiece to realize various machining processes such as milling, drilling, boring, and tapping.

[0003] Announcement No. CN113803412A discloses a swing-type four-axis transmission mechanism with the same speed and force, including a fixed housing and a swing housing, which are rotatably connected in an X-shape. A central shaft runs through the rotation center of the fixed housing and the swing housing, and the central shaft is connected to the output shaft of a rotary drive device, driving gears installed in the fixed housing and the swing housing to rotate simultaneously. The gears in the fixed housing drive two output shafts to rotate at the same speed and force through corresponding driven wheel sets on both sides. The gears in the swing housing drive two other output shafts to rotate at the same speed and force through corresponding driven wheel sets on both sides. The transmission ratios of the two sets of driven wheel sets to the corresponding gears are the same. This invention achieves the same speed and torque output through multiple transmission shafts, and the position of the swing shaft can be changed when needed. It has a simple structure, high integration, and strong environmental adaptability, and can meet the requirements of multi-axis transmission with the same speed and force for moving shafts.

[0004] In the existing technology, the four-axis swing mechanism lacks protection after use and is easily damaged by collision with the outer wall, which seriously affects its service life.

[0005] Therefore, this application proposes a four-axis swing mechanism for machining centers to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing four-axis swing mechanisms, which lack protection after use and are easily damaged by collisions with the outer wall, severely affecting their service life. Therefore, this invention proposes a four-axis swing mechanism for machining centers.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:
