Integrated portal lathe bed

Abstract

The invention discloses an integrated portal lathe bed, which comprises a lathe bed body (10) and a portal frame (20). The lathe bed body (10) and the portal frame (20) are compounded into a whole. The upper end of the portal frame (20) is provided with two X-axis guide rail mounting surfaces (1) in an X direction; an X-axis component mounting groove is arranged between the two X-axis guide rail mounting surfaces (1). The upper part of the portal frame (20) is a U-shaped structure in the direction of the side surface. The portal frame (20) is provided with a tool magazine mounting hole (2). A cuttings discharge groove (8) is arranged in the lathe bed body (10); the lathe bed body (10) is provided with a cuttings discharge hole (5); one end of the cuttings discharge hole (5) is communicated with the cuttings discharge groove (8), and the other end thereof is communicated with the outer side of the lathe bed body (10). The invention has compact structure, small occupation area, high rigidity, convenient processing, high precision retaining ability, short production cycle and low cost and is not easy to deform. The integrated portal lathe bed is especially suitable for being applied to machine tools of small-sized components of pressurization turbine blades and the like.

Description

technical field [0001] The invention relates to an integrated gantry bed. Background technique [0002] The main component of the turbocharger of the automobile engine is the turbocharger, which can improve the overall performance of the engine such as power, economy and emission indicators. Due to the complex surface shape of the turbine blade, it is necessary to use a five-axis linkage high-speed machining center to process the surface shape. [0003] However, there are few five-axis processing machine tools in China, especially the machine tools dedicated to processing supercharged turbine blades are blank, and the price of importing from abroad is too high, which is very uneconomical. [0004] Moreover, the general gantry machine tool in the existing products is composed of bed, gantry and other components, the structure is relatively complex, need to be processed one by one, and then assembled separately; the rigidity is low, and the accumulation of machining errors wi...

[0003] However, there are few five-axis processing machine tools in China, especially the machine tools dedicated to processing supercharged turbine blades are blank, and the price of importing from abroad is too high, which is very uneconomical.

[0004] Moreover, the general gantry machine tool in the existing products is composed of bed, gantry and other components, the structure is relatively complex, need to be processed one by one, and then assembled separately; the rigidity is low, and the accumulation of machining errors will seriously affect the overall accuracy of the machine tool ;Shovel scraping and grinding are required during assembly, and the accuracy cannot be maintained for a long time

Long production cycle and high cost
