The invention relates to a pallet exchanging device of a numerical control machine tool, belonging to the field of a machine tool. The device is characterized by comprising an exchanging table body; a detecting switch, a push-pull cylinder, a sliding plate track, a pallet supporting body and a side detecting switch are respectively fixed on the exchanging table body; the sliding plate track is in parallel to the X shaft of the machine tool; a small sliding plate capable of moving along the track is arranged on the sliding plate track; a bidirectional secondary hydraulic cylinder, the former detecting switch and the latter detecting switch are fixed on the small sliding plate; a positioning block is fixed on the secondary hydraulic cylinder; the push-pull cylinder is fixedly connected with the small sliding plate and can push the small sliding plate to move along the sliding plate track; a positioning cylinder and a parallel rolling track are fixed on the pallet supporting body; a left working pallet is arranged on the parallel rolling track and is located by the positioning cylinder; and a right working pallet is arranged on the X shaft of the machine tool and can move along the X shaft of the machine tool.
Description
technical field [0001] The invention relates to the field of machine tools, and relates to a pallet exchange device for a numerically controlled machine tool. Background technique [0002] As we all know, there are two main types of pallet exchange devices for CNC machine tools: one is rotary exchange, and the other is push-pull exchange. Because the two workpieces to be exchanged are lifted and rotated by the exchange device at the same time, it is only suitable for small-mass workpieces and has certain limitations; the push-pull exchange method can exchange larger-mass workpieces, generally using ordinary hydraulic cylinders or Sprocket drive, these two kinds of drive generally need to occupy a large space, especially when the design space is small, they are greatly restricted. Contents of the invention [0003] In order to overcome the disadvantages of the existing rotary pallet exchange device of CNC machine tools, such as the small exchange quality and the large spa...
