Abstract
The utility model discloses a three-point centering hydraulic clamp for a flywheel cover. The three-point centering hydraulic clamp for the flywheel cover is characterized by comprising a bottom plate (1), wherein a three-point centering component (2), a sequence valve a (3), a sequence valve b (11), supporting columns (4), supporting cylinders (5), corner cylinders (6), and an angular positioning component (10) are sequentially arranged on the bottom plate (1). The three-point centering hydraulic clamp for the flywheel cover has the benefits that three-point centering and positioning is adopted, the center of a workpiece hole and the positioning center of the clamp are consistent, so that the wall of the workpiece hole processed later is guaranteed to be uniform and consistent, and the processing quality of workpieces is stable.
Description
Technical field
The utility model relates to clamping tool for machine work design field, is specifically related to bell housing 10 order three points centering hydraulic pressure clamp for machining.
Background technology
The 10 order clamp for machining centering of flywheel current shell adopt two place's stator rings, the adjective-centre structure of place's spring floating formula guide wheel.Due to the casting batch difference of workpiece blank, the dimensional discrepancy of workpiece blank is larger, cause workpiece Chu Kong center, location and the fixture centre of location to produce relatively large deviation, fixture does not play the effect of centering, cause the workpiece of postorder processing to occur pore wall thickness uneven phenomenon, deviation is excessive, occurs waste product.
Utility model content
In order to overcome above-mentioned defect, the utility model has designed a kind of bell housing three points centering hydraulically operated fixture.
The technical solution of the utility model is achieved in that by pushing away cylinder and promotes 3 equally distributed guide rods, makes the positioning head centering on guide rod.
Bell housing three points centering hydraulically operated fixture, comprises the parts such as clamp bottom board, three points centering assembly, sequence valve a, sequence valve b, support column, shoring, corner cylinder and angle positioning component successively.Three points centering assembly by three points centering seat, centring sleeve, push away cylinder, push rod, thrust flange, guide rod, lining, location guide pin bushing, spring, positioning head and adjusting pad etc. and form.Angle positioning component is made up of riser, scuffing of cylinder bore, angle locating piece etc.It is characterized in that, described three points centering assembly is arranged on clamp bottom board, by adjusting adjusting pad, positioning head is on same circular arc, promotes 3 equally distributed guide rods by pushing away cylinder, makes the positioning head centering on guide rod.Described sequence valve, support column, shoring, corner cylinder are arranged on clamp bottom board.Described angle positioning component is arranged on clamp bottom board, and angle locating piece is arranged on riser, and scuffing of cylinder bore is arranged on riser and connects with angle locating piece.
Workpiece is placed on workpiece on support column by angle orientation, at this moment makes the off-load that mediates of Hydraulic Station magnetic valve, angle locating piece inserts the notch location on workpiece.In oil circuit, after logical oil, the cylinder that pushes away in three points centering assembly promotes push rod, and the positioning head on guide rod is moved, and contact workpiece locating surface is realized three points centering location.By sequence valve, shoring rises fixing afterwards.By sequence valve, corner cylinder is by Work-sheet pressing again.After workpiece processes, oil circuit release, at this moment the scuffing of cylinder bore in angle positioning component retracts angle locating piece, departs from workpiece.In three points centering assembly, push away cylinder and return, push rod is return under the effect of spring, and guide rod drives positioning head to return under spring action, and positioning head departs from workpiece.
The beneficial effects of the utility model are: adopted three points centering location, workpiece hole center is consistent with the fixture centre of location, have ensured that the workpiece hole wall of postorder processing is even all consistent, and workpiece crudy is stable.
