millimeter needs Drilling operation.At present to Eight characters inclined-plane wearing plate or welding manner assembling.There is the bolster Eight characters oblique surface machining technique of similar structures to be: first bolster to be rule on face plate, determine Eight characters inclined-plane, bolster two ends center line, longitudinally determine again the center size in each hole, adopt again plain radial drilling machine to carry out drilling processing, production efficiency is low, and machining accuracy can not be satisfied the demand.
Summary of the invention
The utility model discloses a kind of bolster Special Fixture for Machining according to the deficiencies in the prior art.Problem to be solved in the utility model is to provide a kind of special fixture, adopt this equipment special can bolster be located fixing well, and rotate bolster by hydraulic oil cylinder driving, and the Eight characters inclined-plane of bolster is in a horizontal position, complete rapidly and accurately the drilling processing in 17.5 millimeters of holes of 8 ￠.
The utility model is achieved through the following technical solutions:
Bolster Special Fixture for Machining, comprises the fixed mount of fixing bolster, it is characterized in that: described fixed mount is overall rotating reversing frame, and reversing frame two ends have turning cylinder and fixed frame to be rotationally connected, and wherein one end turning cylinder is also connected with hydraulic oil cylinder driving.
There are the centralized positioning pin and the four jiaos of alignment pins that mate with bolster center bearing in described reversing frame middle part, and four jiaos of alignment pin outsides also have four groups of clamp mechanism, and there is detachable cluster fixture at reversing frame two ends.
Described fixture is one to be folded into trapezoidal binding fixed strip, and fixed strip one end and reversing frame are hinged, and the other end is fixed by openable snap close and reversing frame, on two waists of trapezoidal binding fixed strip, is provided with location drilling.
Described oil cylinder bottom-hinged is in fixed frame, and oil cylinder piston end is axially articulated with and rotates on axial wall perpendicular to turning cylinder.
Described turning cylinder one end and reversing frame are welded and fixed, and the other end is connected and fixed by bearing and fixed frame.
The utility model, according to the size datum on bolster two ends Eight characters inclined-plane drawing requirement and Eight characters inclined-plane, will complete bolster middle part center bearing assembling face and hole and reversing frame centralized positioning pin and four jiaos of alignment pin location of processing, disposable by bolster location, clamping.
Adopt hydraulic oil cylinder driving turning cylinder to rotate bolster, the different Eight characters inclined-plane of bolster is horizontal, be beneficial to drilling processing and implementation.
By the drill bit of the location drilling location radial drilling machine on binding fixed strip, ensure bore position precision.In the time that drilling starts, location drilling plays control drill bit, avoids occurring because workpiece injustice makes drill slipping bore inclined to one side phenomenon, controls drill bit and stably accurately carries out drilling work.
The utility model helpfulness, the utility model adopts centralized positioning pin and four jiaos of alignment pin location bolster, and disposable location clamps, and can complete the drilling processing in 17.5 millimeters of holes of 8 ￠, bolster Eight characters inclined-plane, enhances productivity; Adopt hydraulic oil cylinder driving to rotate bolster, made the each Eight characters of bolster inclined-plane be horizontal level, facilitated drilling processing, alleviated operator's labour intensity; The drill bit that adopts the location drilling location radial drilling machine on binding fixed strip, accurately, overall reversing frame is turning in boring, facilitates bolster handling.
