a workbench structure

Abstract

The invention discloses a workbench structure, which comprises an upper top plate and a lower bottom plate, a plurality of cavity support tubes are arrayed between the upper top plate and the lower bottom plate, and the two ends of the cavity support tubes are respectively connected with the lower surface of the upper top plate and the upper surface of the lower bottom plate. contact, multiple cavity support tubes are filled with epoxy resin, and the outside of multiple cavity support tubes is located between the upper top plate and the lower bottom plate. A cavity structure support tube structure is installed between the upper top plate and the lower bottom plate, replacing the traditional rib structure, which can greatly reduce the weight of the workbench, and it is filled with epoxy resin, which has a low density and can increase the damping of the workbench , reduce the vibration and noise when the workbench is in use, the structure of the present invention is simple, realize the modular design, each part can be processed independently and at the same time, and the shape of each part is relatively simple, it is easier to process, and the overall assembly The process is simple and easy to operate, which can greatly shorten the manufacturing cycle.

Description

technical field [0001] The invention belongs to the field of high-precision, high-speed, high-efficiency five-axis linkage machining centers, and specifically relates to a workbench structure. Background technique [0002] As a suitable equipment for processing complex thin-walled parts, the five-axis machining center is widely used in aerospace processing. As an important functional component of the five-axis machining center, the workbench is the focus and difficulty of research and development. [0003] The traditional workbench is an integrated rib structure. When it is necessary to process larger-sized workpieces, a corresponding large-size workbench is required. At this time, the weight and inertia of the workbench will be very large. Considering the performance of the current motor on the market, The speed, acceleration and machining accuracy will be greatly limited when using the workbench for machining. Therefore, it is necessary to carry out lightweight design for...

[0003] The traditional workbench is an integrated rib structure. When it is necessary to process larger-sized workpieces, a corresponding large-size workbench is required. At this time, the weight and inertia of the workbench will be very large. Considering the performance of the current motor on the market, The speed, acceleration and machining accuracy will be greatly limited when using the worktable

Therefore, it is necessary to carry out lightweight design for the workbench. The traditional lightweight design for the workbench is to optimize the size and layout of the ribs and other structural lightweight design, or to carry out the material lightweight design using lightweight materials, but the reduced The weight is limited, and it is of little help to the improvement of the speed, acceleration and machining accuracy of the worktable.
