Problems solved by technology
[0003] At present, in order to improve the processing capacity, power turrets are generally used on ordinary CNC machine tools, but there are following deficiencies in processing workpieces on such CNC machine tools: 1. The cost of machine tools is too high due to the use of power turrets on CNC machine tools, And the power turret has no advantages in terms of price and speed when processing small products; 2. Due to the large size of the power turret, it brings great inconvenience to the subsequent Y-axis design and installation, and causes the entire machine tool volume bigger
[0004] In addition, in the prior art, there is also a way to install a multi-axis power head on an ordinary CNC machine tool, but the current multi-axis power head can only complete one of the radial or end face processing, and if two ordinary multi-axis power heads are installed The power head will consume a lot of the limited space and stroke of the machine tool, causing interference during processing, and cannot meet the processing needs of some workpieces
[0005] Although some companies on the market have developed cross-spindle multi-axis power head devices, due to structural limitations, the internal bearing span of a single power head unit is too small, resulting in insufficient rigidity, and tool vibration is extremely prone to occur during milling under heavy force
In addition, although some companies have developed a cross power head device with sufficient rigidity, it is difficult to install and use due to the large design structure

The invention discloses a crossed multi-axis power head device used on a numerical control machine tool. The device comprises a plurality of X-axis power shafts, a plurality of Z-axis power shafts, a motor base, a motor, a bearing block and a main shaft base. A drive gear and a power shaft transmission gear set are arranged in the motor base. The power shaft transmission gear set comprises a plurality of X-axis power shaft transmission gears and a plurality of Z-axis power shaft transmission gears, the right ends of the X-axis power shafts are arranged in X-axis bearings in the main shaft base, the left ends of the X-axis power shafts are arranged in X-axis bearings in the bearing block, Z-axis bearings are arranged at the front ends and the rear ends of the Z-axis power shafts, the drive gear is meshed with one X-axis power shaft transmission gear or Z-axis power shaft transmission gear, and each X-axis power shaft transmission gear is meshed with the corresponding Z-axis power shaft transmission gear. By means of the device, machining on the Z-axis end face and the X-axis end face can be completed in multiple procedures can be completed, the whole structure is high in rigidity and small in size, cutters are not prone to vibration during machining, and during operation, the rotation speed is high and noise is low.
Description
technical field [0001] The invention relates to the technical field of numerical control machine tools, in particular to a cross multi-axis power head device used on numerical control machine tools. Background technique [0002] With the development of industry, the requirements for the concentration of the processing procedures of CNC machine tools are getting higher and higher. In order to complete complex processes such as turning, drilling, milling and tapping on one CNC machine tool, it is necessary to improve the processing capacity of traditional CNC machine tools. [0003] At present, in order to improve the processing capacity, power turrets are generally used on ordinary CNC machine tools, but there are following deficiencies in processing workpieces on such CNC machine tools: 1. The cost of machine tools is too high due to the use of power turrets on CNC machine tools, And the power turret has no advantages in terms of price and speed when processing small produc...
