Description
Technical field
The utility model relates to the technical field of structures of the Workpiece fixing of numerically controlled lathe, is specially a kind of numerically controlled lathe hydraulically operated fixture.
Background technology
The Workpiece clamping location of the turbine case of existing numerically controlled lathe, it manually controls clamping, need workman to be opened by chuck three-jaw by hand rotary spanner to be close to turbine case and to guarantee that location puts in place, drive clamping structure by turbine case Workpiece clamping by main shaft pull bar again, its service speed is slow, easily cause turbine case Workpiece fixing unreliable, in clamping process, often occur that locating surface pastes not tight and causes unstable product quality.
Summary of the invention
For the problems referred to above, the utility model provides a kind of numerically controlled lathe hydraulically operated fixture, and it can clamping turbine case rapidly, improve working (machining) efficiency, reduce labor intensity of operating staff, guarantee the uniformity of thrust simultaneously, ensure that locating surface is close to, improve processing dimension stability.
Its technical scheme is such: a kind of numerically controlled lathe hydraulically operated fixture, it is characterized in that, it comprises dual action cylinder, the centre of gyration of described dual action cylinder is provided with pull bar one and pull bar two, described pull bar one is provided with hydraulic pressure multi-jaw chuck, described hydraulic pressure multi-jaw chuck is provided with claw, and it is inner that described pull bar two is set in described pull bar one, and described pull bar two is provided with withstanding tight block.
It is further characterized in that, described pull bar one outer cover is equipped with ring flange, and described hydraulic pressure multi-jaw chuck movable cloth is placed in described ring flange end face;
Described pull bar one end lateral surface is provided with external screw thread, described hydraulic pressure multi-jaw chuck is provided with the internal thread of cooperation, and described pull bar one is fixedly connected with described hydraulic pressure multi-jaw chuck screw thread;
Described hydraulic pressure multi-jaw chuck is hydraulic pressure scroll chuck, the profile of tooth slide block of described hydraulic pressure scroll chuck is provided with three described claws;
Described withstanding tight block comprises three and is evenly arranged between adjacent claw respectively;
Described claw radially inner side upper surface is provided with inverted L-shaped fixture block;
Gap is left between described pull bar two and described pull bar one inwall.
After adopting structure of the present utility model, dual action cylinder first drives pull bar one to move to turbine case, the claw on hydraulic pressure multi-jaw chuck is made to stretch into turbine case inside, claw outwards struts and withstands turbine case medial surface, then dual action cylinder drives pull bar two to move to turbine case, withstanding tight block is made to compress turbine case end face outside, overcome the inefficient defect of manual operation, achieve rapid clamping turbine case, improve working (machining) efficiency, reduce labor intensity of operating staff, claw clamps from inside simultaneously, withstanding tight block holds out against from outside, guarantee the uniformity of thrust, ensure that locating surface is close to, improve processing dimension stability.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is claw structure schematic diagram.
Detailed description of the invention
As shown in Figure 1, a kind of numerically controlled lathe hydraulically operated fixture, it comprises dual action cylinder 1, the centre of gyration of dual action cylinder 1 is provided with pull bar 1 and pull bar 23, dual action cylinder 1 can drive pull bar 1 and pull bar 23 respectively, pull bar 1 is provided with hydraulic pressure scroll chuck 4, the profile of tooth slide block of hydraulic pressure scroll chuck 4 is provided with three claws 5, upper surface is provided with inverted L-shaped fixture block 9 to claw radially inner side, it can catch on turbine case 8 inner chamber better, realize the stationary positioned of turbine case 8 better, it is inner that pull bar 23 is set in pull bar 1, pull bar 23 is provided with three withstanding tight blocks 6 and three withstanding tight blocks 6 are evenly arranged between adjacent claw 5 respectively.
Pull bar 1 outer cover is equipped with ring flange 7, and hydraulic pressure scroll chuck 4 movable cloth is placed in ring flange 7 end face, plays certain position-limiting action, and ring flange 7 can be fixed on the main shaft gyration lathe end face of numerically controlled lathe, and the position realizing the utility model fixture is fixed.
Pull bar 1 end lateral surface is provided with external screw thread, hydraulic pressure scroll chuck 4 is provided with the internal thread of cooperation, and pull bar 1 is fixedly connected with hydraulic pressure scroll chuck 4 screw thread, also other modes can be adopted to connect, and as welding, the utility model adopts screw thread, its connected mode is simple, installs and changes conveniently.
Leave gap between pull bar 23 and pull bar 1 inwall, make pull bar 23 can have the change in location of trace, make withstanding tight block 6 hold out against outside turbine case 8 better.
