Problems solved by technology

In addition, this positioning mechanism is an over-positioning mechanism. During the positioning and exchange process, the positioning mechanism will wear out, and error accumulation will easily occur after a long time, which cannot ensure the accuracy requirements of the entire machine tool; and if the positioning is not accurate, the exchange mechanism and workbench The lower support device rotates when the fit is not tight. When the entire exchange device is in a suspended position and rotates at high speed, the worktable support device and the workbench with the workpiece on the upper part will be separated from the lower exchange mechanism, resulting in serious security incident

Abstract

The invention relates to a double-worktable numerical-control machining center, in particular to a double-worktable exchanging mechanism of a machining center. The double-worktable exchanging mechanism of the machining center comprises a liftable base and two worktable support devices. The two worktable support devices are positioned on the upper side of the base; wireless positioning devices are further arranged on the exchanging mechanism and comprise wireless positioning switches and positioning screws, each wireless positioning switch is fixedly mounted on a side of the corresponding worktable support device, and the positioning screws are arranged on the base and are correspondingly positioned below the wireless positioning switches. The double-worktable exchanging mechanism has the advantages that shortcomings and worry due to mechanical positioning in the prior art can be overcome by wireless positioning mechanisms, the geometric precision of matching between the worktable support devices and the base can be guaranteed after worktables are exchanged, workpieces can be firmly clamped, and accordingly personal casualties or equipment damage due to separation of the two worktable support devices and the base when the two worktable support devices rotate in the air at high speeds can be prevented; the positioning speeds further can be increased, accordingly, the machining efficiency can be greatly improved, and the precision of components can be guaranteed.

Description

technical field [0001] The invention relates to a double-worktable numerical control machining center, in particular to a double-worktable exchange mechanism of the machining center. Background technique [0002] When processing workpieces with short cutting time in batches with machining center machine tools, the loading and unloading time of workpieces accounts for a large proportion of the entire workpiece processing cycle time. In order to reduce processing auxiliary time, an automatically exchangeable multi-station workbench is equipped on the machining center machine tools , so that cutting and auxiliary loading and unloading of workpieces can be carried out simultaneously, and the effective utilization rate of machine tools can be improved. Therefore, the application of exchange worktables in machining centers is becoming more and more common. The positioning mechanism plays a vital role in ensuring the positioning accuracy and repeat positioning accuracy of the excha...
