Machine tool table exchange system for flexible line of gantry machining center

Abstract

The invention discloses a gantry machining center flexible line machine table exchanging system. When the gantry machining center flexible line machine table exchanging system works, a first ball screw drives a main engine sliding base to move to the position corresponding to a main engine tray base along first linear rails, a transport trolley horizontally moves to the position corresponding to the main engine tray base, or a tray warehouse or a loading and unloading station along trolley rails in the X direction, and corresponding work table exchanging action can be carried out; few driving mechanisms are needed by the exchanging system, only a first driving mechanism is arranged on the main engine tray base, and only a second driving mechanism and a third driving mechanism are arranged on the transport trolley; it is supposed that the machine tool table exchanging system is provided with N main engine tray bases, and the function of work table exchanging of the whole exchanging system can be achieved by using (N+2) driving mechanisms. The exchanging system can achieve stable, continuous and fast exchange of the work table, the exchanging requirement of the gantry machining center flexible line machine tool table is met, and the exchanging system is particularly suitable for exchanging heavy and large gantry machining center flexible line work tables.

Description

technical field [0001] The invention relates to a machine tool workbench exchange system, in particular to a machine tool workbench exchange system for a flexible line of a gantry machining center. Background technique [0002] With the advancement of smart factories, the application of flexible manufacturing systems is becoming more and more extensive, and the demand for flexible production lines of machine tools is also increasing. At present, flexible lines with a table top of about 1M×1M are relatively common in the market, and they are mostly found in flexible production lines of horizontal machining centers. However, flexible production lines for gantry machining centers are still relatively rare, especially for large-scale gantry machining centers. The biggest structural feature of the gantry flexible line machining center is that it can realize the interchangeability of worktable components, that is, when the machining center is running, the rest of the workbench ca...

Problems solved by technology

Usually, the driving methods used in the exchange of translational worktables include oil cylinders, sprocket chains, etc., but there are problems of unstable and discontinuous transmission when driving under the flexible line layout of the gantry machining center.
