Description
Technical Field
The invention relates to a metal processing machine, in particular to a processing machine with a horizontal central spindle and double tool towers on two sides.
Background
The existing horizontal, double-spindle and double-turret processing machine (taiwan certificate number M536108 patent) comprises a frame body, a centrally arranged movable shaft seat, a first shaft seat arranged on the frame body and located on one side of the movable shaft seat along a transverse axis, and a second shaft seat arranged on the frame body and located on the other side of the movable shaft seat along the transverse axis. The processing ends of a first main shaft of the first shaft seat and a second main shaft of the second shaft seat face each other (the first main shaft and the second main shaft are parallel or positioned on the same straight line), the first shaft seat and the second shaft seat are respectively provided with cutters, and a first rotating shaft and a second rotating shaft of the movable shaft seat are respectively provided with cutters, so that a workpiece can be processed.
Another three-axis horizontal processing machine (taiwan certificate No. TW M546866) includes a machine table, two processing groups, and a workpiece clamping group, where each processing group has a tool changing mechanism, and the axial directions of the tool changing mechanisms are located on the same first rotation axis.
Although both of the above-described horizontal processing machines have double turret and can achieve the intended processing purpose. However, when the operator wants to perform the tool changing operation on the turret, the turret must be manually rotated to make the tool to be replaced approach to the front side of the machine (i.e., adjacent to the operator's standing position), which results in a relatively long tool changing operation.
In addition, when the tool mounted on the turret performs cutting processing on a workpiece, the turret rotates in a direction toward a standing position of an operator, and chips generated in the cutting processing may strike the operator, possibly causing accidental injury.
