Abstract
The utility model discloses a manual tool changing mechanism which comprises a camshaft, a manual tool hitting body, a guiding plate, a threaded sleeve, a main shaft pull rod, a main shaft and a handle seat, wherein the manual tool hitting body is mounted in the threaded sleeve at the upper end of the main shaft through the guiding plate, the threaded sleeve is arranged at the upper end of the main shaft, the main shaft pull rod is arranged inside the main shaft, an expansion chuck is arranged at the lower end of the main shaft pull rod, the camshaft is arranged inside the manual tool hitting body, the camshaft extends to the handle seat on the outer side of the manual tool hitting body, and a torsion spring is arranged at the tail end of the camshaft. The manual tool changing mechanism provided by the utility model overcomes the defects in the prior art, the design is simple, the structure is reasonable, by using the lever cam principle, the tool changing can be achieved through rotation operation, the operation is convenient, the labor intensity is small, and the tool changing efficiency is high.
Description
Technical field
The utility model relates to Digit Control Machine Tool cutter-exchange mechanism technical field, specifically belongs to manual tool changing mechanism.
Background technology
CNC milling machine can complete mill, the processing of a plurality of operations such as brill, expansion, boring, hinge, its working (machining) efficiency and machining accuracy are higher than engine lathe, more suitable family and teaching are used.Existing CNC milling machine cutter-exchange mechanism is adopted in two ways usually, and the one, promote the cylinder piston motion by cylinder, then thrust is drop-down by piston rod, reach the tool changing purpose.This cutter-exchange mechanism also needs to be equipped with air pump, in the situation that have a power failure or just can not use without source of the gas; Also have kind of the tension of dependence pull bar and become flexible manual tool changing, it is large that this tool changing mode operates labour intensity, and tool change time is long, and efficiency is low.
The utility model content
The purpose of this utility model has been to provide manual tool changing mechanism, has overcome the deficiencies in the prior art, and simplicity of design is rational in infrastructure, by utilizing the lever and cam principle, and the rotating operation tool changing, easy to operate, labour intensity is little, and tool changing efficiency is high.
The technical solution adopted in the utility model is as follows:
Manual tool changing mechanism, comprise camshaft, manually forge a knife body, positioning disk, thread bush, main shaft pull bar, main shaft and handle set, the described body of manually forging a knife is installed in the thread bush of main shaft upper end by positioning disk, thread bush is arranged at the main shaft upper end, be provided with the main shaft pull bar in main shaft, main shaft pull bar lower end is provided with collet, in the body of manually forging a knife, is provided with camshaft, camshaft extends on the handle set of the external side of manually forging a knife, and tail end of camshaft is provided with torsion spring.
Described main shaft upper end is provided with locking nut.
Described main shaft and main shaft pull bar upper end are provided with the dish spring.
Compared with the prior art, the beneficial effects of the utility model are as follows:
The utility model is by utilizing the lever and cam principle, the rotating operation tool changing, and easy to operate, labour intensity is little, and tool changing efficiency is high.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is manually the forge a knife structural representation of body of the utility model.
The specific embodiment
Referring to accompanying drawing, manual tool changing mechanism, comprise camshaft 1, manually forge a knife body 2, positioning disk 3, thread bush 4, main shaft pull bar 5, main shaft 6 and handle set 7, the body 2 of manually forging a knife is installed in the thread bush 4 of main shaft 6 upper ends by positioning disk 3, thread bush 4 is arranged at main shaft 6 upper ends, is provided with main shaft pull bar 5 in main shaft 6, and main shaft pull bar 5 lower ends are provided with collet 8, main shaft 6 is provided with dish spring 9 with main shaft pull bar 5 upper ends, and main shaft 6 upper ends are provided with locking nut.Manually forge a knife in body 2 and be provided with camshaft 1, camshaft 1 extends on the handle set 7 in body 2 outsides of manually forging a knife, and camshaft 1 end is provided with torsion spring 10.
