Summary of the invention
Technical problem to be solved by this invention is, for the shortcoming of above prior art, proposes a kind of turbine Blade Machining special fixture, can not only shorten the process-cycle, and simple in structure, cost is low, and can ensure machining accuracy, improves the quality of products and operating efficiency.
In order to solve the problems of the technologies described above, technical scheme of the present invention is achieved in the following ways: a kind of turbine Blade Machining special fixture, comprise: fan-shaped arc section positioning seat, gripper shoe, pressing plate, base plate, compact heap and revolution pivot pin, horizontally disposed base plate upper surface is provided with fan-shaped arc section positioning seat, one side of fan-shaped arc section positioning seat is connected with gripper shoe by securing member, gripper shoe is also provided with pressing plate away from one end of fan-shaped arc section positioning seat, one end of pressing plate is connected with gripper shoe by being set in revolution pivot pin, and pressing plate can rotate at above-below direction taking revolution pivot pin as axis, the other end of pressing plate is also provided with compact heap, compact heap is connected with fan-shaped arc section positioning seat through pressing plate, fan-shaped arc section positioning seat is also provided with circular arc locating slot near a side of gripper shoe.
Like this, by technical scheme of the present invention, can not only ensure the machining accuracy of turbine blade, improve crudy, can also reduce cost, shorten the process-cycle, improve productivity effect, turbine blade is fixedly clamped with pressing plate and alignment pin, in the time processing a slice, can be fast by the adjusting of pressing plate and alignment pin, reorientate rapidly turbine blade blank, thereby save time, increase work efficiency, and be provided with circular arc locating slot, guarantee accuracy of gauge.
The technical scheme that the present invention further limits is:
Aforesaid turbine Blade Machining special fixture, one end of fan-shaped arc section positioning seat is also provided with locating hole, and by locating hole, stationary fixture fast and accurately, saves time.
The special fixture of aforesaid turbine blade, the gripper shoe that is arranged on fan-shaped arc section positioning seat one side has two at least, and gripper shoe is not all at sustained height, because turbine blade blank is fan-shaped, when not on sustained height, all gripper shoe drawings just can be identical, without special processing, increase work efficiency, reduce assembling difficulty.
The special fixture of aforesaid turbine blade, pressing plate is provided with boss near an end face of fan-shaped arc section positioning seat, is provided with boss, can improve like this compression effect to workpiece, rational in infrastructure, science.
The special fixture of aforesaid turbine blade, compact heap is hexagon socket cap head screw, can reduce costs like this, simple to operate.
The special fixture of aforesaid turbine blade, the through hole that pressing plate coordinates with compact heap is U-shaped groove, owing to often processing a slice turbine blade blank, compact heap must be readjusted once, make trip bolt have enough adjustable ranges by U-shaped groove, ensure that compact heap can compress blade blank, and simple in structure, easy to process.
The invention has the beneficial effects as follows: by technical scheme of the present invention, can not only shorten the process-cycle, simple in structure, cost is low, and can ensure machining accuracy, improves the quality of products and operating efficiency.
