Transporting trolley for gantry multi-tray exchange system

Abstract

The invention discloses a transporting trolley for a gantry multi-tray exchange system. A support, a first oblique sliding base and a second oblique sliding base of the transporting trolley are integrally arranged on a transporting track, and the movement of the transporting trolley along a first linear rail on the transporting track is achieved through engagement of a first drive gear and a first rack. Compared with a manner that a traditional double-exchange workbench gantry machining center exchanges workbenches through an oil cylinder and a chain transmission system, the gear and rack transmission manner of the transporting trolley is continuous and stable in action, the transmission precision and reliability are greatly improved, precision retentivity is good, and the workbench transmission precision can be ensured; meanwhile, the problem that after the traditional chain transmission system is used for a long term, a chain is stretched, and consequently precision is lowered can be effectively solved; and the transporting trolley is adjustable in height, and stable and smooth exchange of the workbenches between a machining center main machine and the transporting trolley or between the transporting trolley and a tray warehouse or an unloading and loading station can be achieved.

Description

technical field [0001] The invention relates to a transport trolley, in particular to a transport trolley for a gantry multi-pallet exchange system. 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 exchange of worktables, that is, when the machining center is running, the rest of the worktables can be disassembled at the loading and unloading station or waiting fo...

AI Technical Summary

Problems solved by technology

For the "two-by-two" leveling between the machining center and the main machine pallet seat matched with the machining center, it is relatively easy to realize in assembly, while for other adjustments such as between the transport trolley and the main machine pallet seat or pallet warehouse or loading and unloading station Flat, difficult to assemble

It will be a difficult task for the installers if all the workbenches of the main engine, the pallet base of the main engine, the transport trolley, the pallet warehouse and the workbench of the loading and unloading station are all adjusted to the same level
