Detailed description of the invention
Below in conjunction with accompanying drawing, a specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention not by the restriction of detailed description of the invention.It will be appreciated that, mentioned in following embodiment of the present invention " on ", D score, "left", "right", " front " and " reverse side " all with the direction shown in each figure for benchmark, these words being used for limiting direction are only used to be convenient to illustrate, do not represent the restriction to the concrete technical scheme of the present invention.
As depicted in figs. 1 and 2, bottom surface, cylinder block top hydraulically operated fixture of rough milling of the present invention is by original activity orientation mechanism of rough milling bottom surface, cylinder block top fixture and locating as the main shaft semicircle orifice that two stationary positioned blocks that vertical direction (parallel with bottom surface, top) is located change cylinder block front and back end into using the false boss of two on cylinder block left surface, specifically comprise: base 1 and the oil cylinder supporting base 2 being symmetricly set on these base 1 two ends, positioning support 3, and be symmetricly set on base 1 and oil cylinder supporting base 2, left surface detent mechanism on positioning support 3 and main shaft semicircle orifice activity orientation mechanism.
Wherein, main shaft semicircle orifice activity orientation mechanism comprises: horizontal activity orientation mechanism and coordinate longitudinal backup mechanism of positioning cylinder body with this horizontal activity orientation mechanism.
As shown in Figure 2, horizontal activity orientation mechanism comprises: hydraulic jack 41, joint 42, the axis of guide 43, activity orientation block 44 and pin 45.Hydraulic jack 41 is laterally arranged on the fixing hole of oil cylinder supporting base 2, for driving activity orientation block 44 positioning spindle semicircle orifice.
Joint 42 is column, activity is located in the first pilot hole of positioning support 3, left end (near cylinder block one end to be positioned) has the pin-and-hole longitudinally offered, and right-hand member is screwed on the piston rod of hydraulic jack 41, make its under the driving of hydraulic jack 41 in the first pilot hole transversal stretching; The right-hand member of the first pilot hole is provided with stop collar 31; Also be provided with jointing washer 411 between the piston rod of joint 42 and hydraulic jack 41, its effect is the stroke of adjustment hydraulic jack 41.
Positioning support 3 also offers second pilot hole parallel with the first pilot hole, fairlead 32 is provided with in second pilot hole, the horizontal activity of the axis of guide 43 is located in the fairlead 32 of the second pilot hole, and be connected with the left end pin-and-hole of joint 42 by pin 45, activity orientation block 44 is fixed on the left end of the axis of guide 43, be connected with hydraulic jack 41, side, activity orientation block 44 front end is the arc with main shaft semicircle orifice adaptation to be positioned.Be provided with locating piece adjusting pad 441 between activity orientation block 44 and the axis of guide 43, its effect is the positioning precision of adjustment activity orientation block 44.Due to the reciprocating motion of hydraulic jack 41 piston rod, activity orientation block 44 is driven to move forward and backward by joint 42, pin 45, the axis of guide 43.The effect of stop collar 31 is strokes of restriction hydraulic jack 41 piston rod.This detent mechanism is designed to movable structure, mainly can realize workpiece (cylinder block) location when activity orientation block 44 stretches out, can abdicate space be convenient to work-handling when activity orientation block 44 retreats.The separately design of activity orientation block 44 and the axis of guide 43, the replacing advantageously after the precision adjustment and wearing and tearing of activity orientation block 44.
Longitudinal backup mechanism comprises: the oil cylinder (not shown) of hook pressing plate 51 and this hook pressing plate 51 of driving, one end longitudinally-moving of this hook pressing plate 51 is arranged on positioning support 3, the other end (hook end) extend in cylinder block camshaft hole, during positioning cylinder body, activity orientation block 44 stretches into cylinder block main shaft semicircle orifice, hook pressing plate 51 promotes cylinder block and moves to activity orientation block 44 under the drive of oil cylinder, pushes against main shaft semicircle orifice realize accurately location to make activity orientation block 44.
Left surface detent mechanism symmetry is arranged on base 1 two ends, specifically comprises: main left surface locating piece 61, auxiliary left side locating piece 62 and right flank pressing plate 63, and drives the oil cylinder of this right flank pressing plate 63.Main left surface locating piece 61 and auxiliary left side locating piece 62 symmetry are arranged on in-plane two ends on base 1, form a horizontal plane, for the left surface of positioning supports cylinder block 7, wherein, auxiliary left side locating piece 62 is the cylinder block left surface location in order to adapt to different type of machines.Right flank pressing plate 63 is arranged on oil cylinder supporting base 2.Left surface detent mechanism and cylinder block semicircle orifice activity orientation mechanism form a complete workpiece positioning system.
As shown in Figures 2 to 4, before fixture loaded onto by workpiece, right flank clamp block 63 and hook pressing plate 51 are in releasing orientation, do not contact with workpiece (cylinder block); Activity orientation block 44 with hydraulic jack 41 back to extreme position so that workpiece (cylinder block) lifting.Composition graphs 5 can be found out, treat that cylinder block 7 hangs on fixture, the left surface of cylinder block 7 is fitted after main left surface locating piece 61, auxiliary left side locating piece 62, hydraulic jack 41 travels forward, and drives activity orientation block 44 to arrive forward the position of locating with the main shaft semicircle orifice of cylinder block 7 by joint 42, pin 45, the axis of guide 43.Then, hook pressing plate 51 promotes cylinder block 7 under the drive of oil cylinder, makes main shaft semicircle hole wall and activity orientation block 44 close contact of cylinder block 7, thus realizes reliable location.Finally, four right flank pressing plates 63 at two ends, left and right are from two ends compression cylinder body right flank, and cylinder block 7 just can carry out bottom surface, top Milling Process.After processing, right flank pressing plate 63 and hook pressing plate 51 unclamp, and hydraulic jack 41 moves backward, and drive activity orientation block 44 to move backward, avoid the main shaft semicircle orifice of cylinder block 7, cylinder block 7 can hang fixture smoothly.
It is simple and reasonable, easy and simple to handle that this rough mills bottom surface, cylinder block top hydraulically operated fixture, using the position error that main shaft semicircle orifice causes as the positioning datum rough milling bottom surface, cylinder block top operation to reduce positioning datum disunity; Meanwhile, activity orientation block and the axis of guide separate and design, the replacing advantageously after activity orientation block carries out accurate adjustment and wearing and tearing.
Be only several specific embodiment of the present invention above, but the present invention is not limited thereto, the changes that any person skilled in the art can think of all should fall into protection scope of the present invention.
