The universal fixture device comprises a base. The universal fixture device is characterized in that two blade tip shroud support plates and two blade root support plates are installed at the two transverse ends of the base respectively, blade tip shroud pressing plates are installed on the base and located at the longitudinal outer side ends of the two blade tip shroud support plates respectively, blade root pressing plates are installed on the base and located on the longitudinal outer side ends of the two blade root support plates respectively, blade root clamping bases are further installed on the base and located at the longitudinal outer side ends of the two blade root support plates respectively, a reverse-L-shaped groove is formed in the top surface of each blade root clamping base, alignment blocks used for longitudinal locating of a blade forge piece are placed in the reverse-L-shaped grooves of the two blade root clamping bases and are tightly close to the inner walls of the reverse-L-shaped grooves, the two blade root clamping bases are respectively provided with a longitudinal threaded through hole, and locking screws are installed in the threaded through holes.
Description
Technical field
The utility model relates to blade processing tooling field, especially relates to the frock field of civil aviation engine flow guiding aluminium alloy vane overall length processing, is specially a kind of universal fixturing device for the processing of blade overall length.
Background technology
Blade forging top and bottom surface after forging have a withdrawing pattern inclined-plane, for meeting design requirement, need after forging, milling blade forging both ends of the surface make blade overall length reach design load.Machining blade overall length was the mode that adopts square chest location in the past: first with pre-determined bit fixture, blade forging is positioned in square chest, then in square chest, pour into a mould sn-bi alloy, cooling until remove pre-determined bit fixture after fully solidifying with blade forging until sn-bi alloy, 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 design independent pre-determined bit fixture, thereby the production cycle of blade forging is long, and production efficiency is low.
Summary of the invention
For the problems referred to above, the utility model provides a kind of universal fixturing device for the processing of blade overall length, and it can solve the problem that production cycle is long, production efficiency is low that the processing of blade overall length adopts square chest locate mode to exist.
Its technical scheme is such, it comprises 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, be positioned at described two integral shroud support plates, longitudinal outboard end of two blade root support plates is separately installed with integral shroud pressing plate, blade root pressing plate, on described base, the longitudinal outboard end that is positioned at described two blade root support plates is also separately installed with blade root clamping seats, described blade root clamping seats end face is provided with anti-L shaped groove, for blade forging longitudinal register line piece is positioned in the anti-L shaped groove of two blade root clamping seats and near the internal groove side wall of described anti-L shaped groove, described two blade root clamping seats have longitudinal tapped through hole, in described tapped through hole, lock-screw is installed, blade forging to be processed is supported by described integral shroud support plate and blade root support plate, by described, line piece is alignd and carries out longitudinal register 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 in that:
Described integral shroud pressing plate, blade root pressing plate are all installed on described base by trip bolt, and by described trip bolt, blade forging are compressed;
On described integral shroud pressing plate, blade root pressing plate, all have mounting hole, described trip bolt is installed on described integral shroud pressing plate, blade root pressing plate on described base through after described mounting hole.
The square chest localization method adopting during with machining blade forging overall length in the past carrys out comparison, the beneficial effect of the utility model grip device is: it is simple in structure, easy to use, for the location reliable clamping of blade forging, can greatly shorten the production cycle, enhance productivity; For the overall length processing of dissimilar blade, owing to all having mounting hole on its integral shroud pressing plate, blade root pressing plate, therefore the adjustment of adaptability position can be carried out according to dissimilar blade in the position of integral shroud pressing plate, blade root pressing plate, therefore its versatility, clamping is reliable, can greatly improve the utilization rate of frock, reduce frock deployment cost.
