Abstract
The invention provides a machine tool spindle quick cutter changing combination mechanism connected to a numerically-controlled machine tool spindle. A pulling rod is arranged in the spindle. The cutter changing combination mechanism body pushes the pulling rod to change a cutter and comprises a manipulator, a pressure bearing component, a return spring and a plug. The manipulator squeezes the pressure bearing component connected with the plug and the return spring. The return spring wraps the outer diameter of the plug, and the pulling rod built in the spindle is arranged below the plug. A connecting seat is arranged below the pressure bearing component, the pressure bearing component and the top of the connecting seat are provided with a spatial structure, and the height of the spatial structure is larger than the stretchable length of the return spring. The connecting seat is fixedly connected with the spindle and wraps the plug. A countersink is formed in the connecting seat, and the return spring is arranged between the countersink of the connecting seat and the pressure bearing component. The machine tool spindle quick cutter changing combination mechanism is simple in structure and high in cutter changing speed, and operating efficiency of the machine tool is improved accordingly.
Description
Technical field
The present invention relates to a kind of machine tool chief axis rapid changing knife combined mechanism, belong to machine tool technology field.
Background technology
The cutter-exchange mechanism of Digit Control Machine Tool is generally cam-type, fluid pressure type, link-type and gear type, moreover is the combination of various mechanism form.The tool changing combined mechanism tool-changing speed of this kind of traditional structure form is slower, generally needs to carry out continuously a plurality of actions, just carries out tool changing action, therefore, how can improve tool-changing speed, is the technical problem to be solved in the present invention.
Summary of the invention
The invention provides a kind of machine tool chief axis rapid changing knife combined mechanism, this mechanism's tool-changing speed is fast.
For solving above technical problem, the invention provides following technical scheme: a kind of machine tool chief axis rapid changing knife combined mechanism, described tool changing combined mechanism is connected in main shaft of numerical control machine tool, in main shaft, be provided with pull bar, this tool changing combined mechanism pushing drawing rod carries out tool changing, described combined mechanism comprises mechanical arm, pressure part, back-moving spring and piston, mechanical arm extruding pressure part described in described pressure part, pressure part connects piston and back-moving spring, back-moving spring is wound in piston external diameter, and the below of piston is the built-in pull bar of main shaft; Described pressure part below is provided with Connection Block, and pressure part and Connection Block top have space structure, and the height of this space structure is greater than back-moving spring Extensible; Described Connection Block is fixedly connected with main shaft, Connection Block parcel piston; In Connection Block, have counterbore, back-moving spring is arranged between Connection Block counterbore and pressure part.
Further, described pressure part is tube structure, comprises pressing plate and the barrel that press on mechanical arm top.
Further, between described barrel and Connection Block, be provided with linear bearing.
Further, the connector between described Connection Block and main shaft is screw.
Further, described Connection Block top has top cover, top cover with in Connection Block, adopt screw to be connected.
This machine tool chief axis rapid changing knife combined mechanism the present invention relates to, simple in structure, tool-changing speed is high, and then has improved the operating efficiency of lathe.
Accompanying drawing explanation
Fig. 1 is machine tool chief axis rapid changing knife combined mechanism structural representation of the present invention.
The specific embodiment
As shown in Figure 1, tool changing combined mechanism is connected in main shaft of numerical control machine tool 1, in main shaft, be provided with pull bar 2, this tool changing combined mechanism pushing drawing rod 2 carries out tool changing, described combined mechanism comprises mechanical arm 8, pressure part 7, back-moving spring 6 and piston 3, mechanical arm extruding pressure part 7 described in described pressure part 7, and pressure part 7 connects piston 3 and back-moving springs 6, back-moving spring 6 is wound in piston 3 external diameters, and the below of piston 3 is the built-in pull bar of main shaft 2; Described pressure part 7 belows are provided with Connection Block 4, and pressure part 7 has space structure with Connection Block 4 tops, and the height of this space structure is greater than back-moving spring 6 Extensibles; Described Connection Block 4 is fixedly connected with main shaft 1, Connection Block 4 parcel pistons; In Connection Block 4, have counterbore, spring 6 is arranged between Connection Block counterbore and pressing plate.
