Description

Technical Field

[0001] The utility model relates to the technical field of swing heads, in particular to an A-axis box structure of a swing head. Background Art

[0002] The AC head of a machine tool refers to a device used in a five-axis machining center or other CNC machine tools to realize multi-degree-of-freedom positioning and processing of workpieces in space. The working principle of the AC head is based on two rotating coordinates, namely the A axis and the C axis. The two axes realize rotational motion through their respective drive systems. During the processing, the A axis and the C axis can rotate synchronously or independently as needed to adapt to workpieces of different shapes and processing requirements, where the A axis can rotate around the vertical axis and the C axis can rotate around the horizontal axis.

[0003] In order to achieve the rigidity of use, the A-axis box structure of the swing head is usually designed to be bloated, which reduces the applicability of the AC swing head. The conventional leg structure with the same width at the top and bottom has a very large structure and weight, which seriously limits the dynamic performance of the swing head's rotational motion and increases the deformation of its own weight, resulting in reduced swing head accuracy. When the machine tool swing head needs to process high-hardness and high-strength materials (such as titanium alloy, high-strength steel, etc.), the greater the cutting force will be, the worse the relative machinability will be. The common single-drive, single-turntable bearing-supported swing head cannot meet the cutting force and load-bearing rigidity requirements. Utility Model Content

[0004] The main purpose of the utility model is to provide a swing head A-axis box structure to solve the problem of a swing head A-axis box structure proposed in the related art.

[0005] In order to achieve the above-mentioned purpose, according to one aspect of the utility model, a swing head A-axis box structure is provided, including: an A-axis box, the A-axis box upwardly supports the C-axis component, the A-axis box is provided with a spindle component, a cavity is opened above the A-axis box, a left driving stator is fixedly arranged on the left side of the cavity, and a right driving stator is fixedly arranged on the right side of the cavity, and the left driving stator and the right driving stator are symmetrically arranged.

[0006] Furthermore, a left driving rotor is rotatably provided on the left driving stator, and a right driving rotor is rotatably provided on the right driving stator.

[0007] Furthermore, a left connecting plate is fixedly arranged under the left driving rotor, one end of which is fixedly connected to one side of the main shaft component, and a right connecting plate is fixedly arranged under the right driving rotor, one end of which is fixedly connected to the other side of the main shaft component.

[0008] Furthermore, a cavity is opened at the lower inner part of the A-axis housing, a left turntable bearing is arranged on the left side of the cavity, and one end of the left turntable bearing is connected to one end of the main shaft component.

[0009] Furthermore, a right turntable bearing is arranged on the right side of the cavity, and one end of the right turntable bearing is connected to the other end of the main shaft component.

[0010] Furthermore, the A-axis box has a structure that is wide at the top and narrow at the bottom.

[0011] Compared with the prior art, the utility model has the following beneficial effects: the A-axis box adopts a wide upper and narrow lower structure, which can achieve a good balance between the box support rigidity and the box lightweight. The lightweight A-axis box structure enables the swing head to have excellent dynamic response performance, effectively reducing the weight of the A-axis while greatly increasing its support rigidity and dynamic performance, so that the swing head can achieve higher precision and better stability, and at the same time has higher support rigidity and higher working accuracy than the conventional box structure swing head. The A-axis box structure adopts a dual motor drive structure and a dual turntable bearing support structure, achieving high cutting capacity, high rigidity and high precision.
