Description

Universal clamp device for vane overall length processing
Technical field
The present invention relates to blade processing tooling field, especially relate to the frock field of civil engine water conservancy diversion aluminium alloy vane overall length processing, particularly for the Universal clamp device of vane overall length processing.
Background technology
Blade forging top after forging and bottom surface have a withdrawing pattern inclined-plane, for meeting design requirement, milling blade forging both ends of the surface vane overall length need to be made to reach design load after forging.Processing vane overall length was the mode adopting square chest location in the past: first with pre-determined bit fixture by blade forging location to square chest, then in square chest, pour into a mould sn-bi alloy, until sn-bi alloy cooling until removing pre-determined bit fixture with blade forging after fully solidifying, Milling Machining blade forging both ends of the surface, until blade forging overall length meets design requirement, finally remove square chest.This localization method work step is many, long processing time, and different piece number products need to design independent pre-determined bit fixture, thus the production cycle of blade forging is long, and production efficiency is low.
Summary of the invention
For the problems referred to above, present invention provide for the Universal clamp device of vane overall length processing, it can solve vane overall length processing and adopt the production cycle length that square chest location mode exists, the problem that production efficiency is low.
Its technical scheme is such, it includes base, it is characterized in that: the transverse ends of described base is separately installed with integral shroud support plate and blade root support plate, described integral shroud support plate and blade root support plate are provided with two, on described base, it is positioned at said two integral shroud support plate, the longitudinally outboard end of two blade root support plates is separately installed with integral shroud pressing plate, blade root pressing plate, on described base, the longitudinally outboard end being positioned at said two blade root support plate is also separately installed with blade root clamping seats, described blade root clamping seats end face is provided with backward L-shaped groove, line block is positioned in the backward L-shaped groove of two blade root clamping seats and against the internal groove side wall of described backward L-shaped groove for blade forging longitudinal register, said two blade root clamping seats has longitudinal tapped through hole, in described tapped through hole, lock-screw is installed, blade forging to be processed is by described integral shroud support plate and the supporting of blade root support plate, longitudinal register is carried out by described line block alignd with the positioning marking on described blade root inner arc, and by integral shroud pressing plate, blade root pressing plate compresses and lock-screw locking.
It is further characterized by
Described integral shroud pressing plate, blade root pressing plate are installed on described base each through trip bolt, and are compressed by blade forging by described trip bolt;
All having mounting hole on described integral shroud pressing plate, blade root pressing plate, described integral shroud pressing plate, blade root pressing plate are installed on described base by described trip bolt after described mounting hole.
The square chest localization method adopted during with processing blade forging overall length in the past compares, having the beneficial effects that of present clip device: its simple in construction, easy to use, location reliable clamping for blade forging, it is possible to be greatly shortened the production cycle, improves production efficiency;Overall length for dissimilar blade is processed, owing to its integral shroud pressing plate, blade root pressing plate all having mounting hole, therefore integral shroud pressing plate, blade root pressing plate position can carry out the adjustment of adaptability position according to dissimilar blade, therefore its versatility, clamping is reliable, the utilization rate of frock can be greatly improved, reduce frock deployment cost.
Accompanying drawing explanation
Fig. 1 is that the present invention does not install the main TV structure schematic diagram under integral shroud pressing plate, blade root pressing plate state for the Universal clamp device that vane overall length is processed;
Fig. 2 is the plan structure schematic diagram of the Universal clamp device that the present invention processes for vane overall length;
Fig. 3 is by the schematic diagram that line block and the positioning marking on blade forging blade root inner arc come locating blades forging in Universal clamp device of the present invention.
Detailed description of the invention
See Fig. 1~Fig. 3, Universal clamp device of the present invention, it includes base 2, the transverse ends of base 2 is separately installed with integral shroud support plate 1 and blade root support plate 3, integral shroud support plate 1 and blade root support plate 3 are provided with two, on base 2, it is positioned at two integral shroud support plates 1, the longitudinally outboard end of two blade root support plates 3 is separately installed with integral shroud pressing plate 5, blade root pressing plate 6, on base 2, the longitudinally outboard end being positioned at two blade root support plates 3 is also separately installed with blade root clamping seats 4, blade root clamping seats 4 end face is provided with backward L-shaped groove 9, for in the backward L-shaped groove 9 that line block 8 is positioned over two blade root clamping seats 4 of blade forging longitudinal register and against the internal groove side wall 10 of backward L-shaped groove 9, two blade root clamping seats 4 have longitudinal tapped through hole, lock-screw 7 is installed in tapped through hole, blade forging 11 to be processed is supported by integral shroud support plate 1 and blade root support plate 3, longitudinal register is carried out by line block 8 is alignd with the positioning marking on blade root inner arc, and by integral shroud pressing plate 5, blade root pressing plate 6 compresses and lock-screw 7 is locked.Integral shroud pressing plate 5, blade root pressing plate 6 are installed on base 2 each through trip bolt 12, and are compressed by blade forging by trip bolt 12;All having mounting hole 13 on integral shroud pressing plate 5, blade root pressing plate 6, corresponding integral shroud pressing plate 5 or blade root pressing plate 6 are installed on base 2 by trip bolt 12 after mounting hole 13.
Below in conjunction with accompanying drawing, specifically describe the process of present clip device positioning and clamping blade forging: first unclamp the trip bolt 12 on integral shroud pressing plate and blade root pressing plate and lock-screw 7, the inner arc of blade forging to be processed is lain in integral shroud support plate 1 upward, on blade root support plate 3, to the two ends of line block 8 be positioned in the backward L-shaped groove of two blade root clamping seats 4 and against the internal groove side wall 10 of backward L-shaped groove 9, then utilize blade forging blade root inner arc positioning marking to be processed with described to line block positioned in alignment, take away line block 8 behind location, then respectively through integral shroud pressing plate 5, mounting hole 13 on blade root pressing plate 6 regulates integral shroud pressing plate 5, integral shroud convex surface and blade root intrados is compressed respectively behind the position of blade root pressing plate 6, namely tighten lock-screw 7 presses the clamping of blade forging location complete.
