Abstract
Disclosed is a tool changing mechanism of a gear shaping machine. The tool changing mechanism of a gear shaping machine comprises a tool rest body, the inside of the tool rest body is provided with a tool shaft, and the inside of the tool shaft is provided with an oil cavity; an oil cavity inlet at the top end of the tool shaft is provided with a ball joint drawbar and provides high-pressure oil through the ball joint drawbar; the bottom end of the tool shaft is arranged inside the oil cavity and provided with a tool retracting mechanism, the tool retracting mechanism comprises a piston rod, a spring is sleeved outside the lower portion of the piston rod, and the bottom end of the piston rod is provided with a catch jaw; a tool changing seat is arranged under the spring, the inside of the tool changing seat is provided with a pop rivet, the upper end of the pop rivet is matched with the catch jaw, the low end of the pop rivet is connected with a tool bar, and the lower portion of the tool bar is fixedly provided with a tool. The tool changing mechanism of the gear shaping machine replaces a traditional screw locking mode into an elastic deforming force locking mode of the Belleville spring, overcomes the shortcoming that the action force of a tool rest indexing worm gear pair is required during tool assembly of an existing gear shaping machine tool to result in damage to the precision of the tool rest indexing worm gear pair, reduces the machine tool operating difficulty and the operating time and is convenient to operate, simple in structure, wide in application range and particularly applicable to a small or medium size numerical control machine tool.
Description
Technical field
The present invention relates to a kind of gear shapping machine cutter-exchange mechanism.
Background technology
The output of domestic existing shaping machine is very large, particularly middle-size and small-size gear shapping machine.Tool-post structure is as a core precise part of shaping machine, and its operating accuracy directly affects the overall precision of lathe, and replacing, the installation of the process tool in tool-post structure are very frequently.Replacing, the installation of the cutter of existing gear shapping machine are all directly carried out on lathe, the workload of operation is very large, time is long, thereby particularly in the time of loose cutter, tight cutter, need to damage by the active force cutter setting frame index worm gear pair precision of tool-post structure index worm gear pair, thereby reduce the machining accuracy of lathe.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of gear shapping machine cutter-exchange mechanism, overcome the time shortcoming such as long and destruction machine tool accuracy of time length, complicated operation, time of existing shaping machine tool changing, dress cutter, reduce the operation easier of lathe, reduce the operating time, guaranteed the overall precision of lathe.
The object of the present invention is achieved like this:
A kind of gear shapping machine cutter-exchange mechanism, it comprises tool-post structure, in tool-post structure, be provided with cutter shaft, in cutter shaft, be provided with oil pocket, the oil pocket entrance on cutter shaft top is provided with ball pull bar, provide hydraulic oil by ball pull bar to oil pocket, cutter shaft bottom is positioned at oil pocket and is provided with retraction mechanism, and described retraction mechanism comprises piston rod, under piston rod, is arranged with spring, piston rod bottom is provided with pulling claw, spring bottom is provided with tool changing seat, in tool changing seat, is provided with blind rivet, and blind rivet upper end coordinates with pulling claw, blind rivet lower end connects knife bar, under knife bar, is installed with cutter.
Above-mentioned cutter is fixed on knife bar by nut.
Above-mentioned spring is disc spring or dish spring.
The present invention has obtained following technique effect:
The present invention has replaced conventional screw locking mode with the elastic deformation force's of disk spring locking mode, thereby the shortcoming that need to damage by the active force cutter setting frame index worm gear pair precision of knife rest index worm gear pair while overcoming existing shaping machine mounting cutter, the operation easier that has reduced lathe, has reduced the operating time; Easy to operate, simple in structure, applicability is wide, is specially adapted to the application of middle-size and small-size Digit Control Machine Tool.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is structural representation of the present invention;
Fig. 2 is bottom of the present invention enlarged diagram.
The specific embodiment
As shown in Figure 1-2, a kind of gear shapping machine cutter-exchange mechanism, it comprises tool-post structure 1, in tool-post structure, be provided with cutter shaft 2, in cutter shaft, be provided with oil pocket 12, the oil pocket entrance on cutter shaft top is provided with ball pull bar 10, provides hydraulic oil by ball pull bar to oil pocket, and cutter shaft bottom is positioned at oil pocket and is provided with retraction mechanism, described retraction mechanism comprises piston rod 3, under piston rod, be arranged with spring 4, piston rod bottom is provided with pulling claw 5, and spring bottom is provided with tool changing seat 11, in tool changing seat, be provided with blind rivet 6, blind rivet upper end coordinates with pulling claw, and blind rivet lower end connects knife bar 7, is installed with cutter 9 under knife bar.Described cutter is fixed on knife bar by nut 8.Described spring is disc spring or dish spring.
Implementation step of the present invention is as follows:
1, provide hydraulic oil by ball pull bar 10, through the oil pocket 12 of cutter shaft 2, promote piston rod 3, make pulling claw 5 unclamp blind rivet 6, thereby knife bar 7 is exited from cutter shaft together with nut 8, cutter 9 entirety;
2, the knife bar that cutter is housed 7 taking off from lathe is arranged on to tool changing seat 11, unclamps nut 8 and take out, take off the cutter 9 that needs replacing, load onto new cutter 9, fastening nut 8, takes out knife bar 7 from tool changing seat 11, and tool changing completes;
3, the knife bar 7 of more finishing changing cutter 9 is inserted to cutter shaft 2, the hydraulic oil providing by ball pull bar 10 disconnects, and at effect lower piston rod 3 rollbacks of dish spring 4, makes pulling claw 5 strain blind rivet 6, thus locking knife bar 7, and lathe tool changing, the whole process of dress cutter complete.
