Description

Centering hydraulic center frame
Technical field:
The utility model relates to a kind of centre frame, is specially a kind of centering hydraulic center frame.
Background technology:
The closed center rest that horizontal lathe uses is upper and lower two body combining structures, three centripetal mandrel holding workpieces.Need during clamping workpiece to open centre frame upper body, closing body after loading workpiece, rotational workpieces is according to round numerical value of beating, and the axial internal clearance of adjustment mandrel, the pivot of the bearing center and workpiece that reach centre frame overlaps.Work pieces process completes, and opens centre frame upper body again, unloads workpiece.Such work, the workpiece adjustment concentric time is long, and efficiency is not high.Can the device of a kind of quick centering of utility model, shorten non-cutting time, enhance productivity.Through design demonstration repeatedly, we find the scheme addressed this problem finally, and that adopts centering hydraulic mechanism exactly.
Utility model content:
In order to solve the problem existing for background technology, the utility model provides by the following technical solutions:
A kind of centering hydraulic center frame, comprises the base below semicircular upper bracket and semicircular lower carriage and lower carriage, described upper bracket and lower carriage one end hinged, the other end is connected by connecting bolt, and described upper bracket is provided with jacking block at least one; Described lower carriage is provided with two lower jacking blocks, and described lower jacking block is fixed on a support plate, and described support plate is by eccentric stiffener and coarse adjustment mechanism controls; Described eccentric stiffener comprises slide block and eccentric wheel, and described slide block is located at below support plate, and described slide block is driven by the eccentric wheel below it.
Described coarse adjustment mechanism comprises the connecting rod being located at support plate side, and described connecting rod is by lower Driven by Hydraulic Cylinder.
Hydraulic center frame has four jacking blocks, and two, bottom jacking block is embedded on a support plate, and when moving up and down position, its bearing center left and right is constant; Two, top jacking block each freedom small cylinder controls its clamping and unclamps.When diameter of work changes, first unclamp eccentric stiffener, then use hydraulic means fast servo two lower jacking blocks, then use eccentric stiffener accurate adjustment center, then lock eccentric stiffener.Close centre frame upper cover, each upper jacking block hydraulic clamp.Only need to retract upper jacking block during dismounting workpiece, open centre frame upper body, hang out workpiece.
In eccentric stiffener, rotated by rotating shaft and change eccentric radial variations, support well.Be Cylindrical Surfaces Contact between eccentric wheel and slide block, increase contact rigidity.Although slide block offsets with eccentric rotation, its bearing center line crosses axle center all the time, therefore can not produce torque reaction.Be plane contact between slide block and rest pad, centre is connected by feather key, has well supporting and guide effect.
Accompanying drawing illustrates:
Fig. 1 is the utility model Facad structure schematic diagram;
Fig. 2 is the utility model Facad structure sectional view;
Fig. 3 is the utility model side structure sectional view.
Detailed description of the invention:
See accompanying drawing, a kind of centering hydraulic center frame, comprise the base 3 below semicircular upper bracket 1 and semicircular lower carriage 2 and lower carriage 2, described upper bracket 1 is hinged with lower carriage 2 one end, the other end is connected by connecting bolt 4, and described upper bracket 1 is provided with jacking block 5 at least one; Described lower carriage 2 is provided with two lower jacking blocks 6, and described lower jacking block 6 is fixed on a support plate 7, is provided with slide block 8 below described support plate 7, and slide block 8 is driven by the eccentric wheel 9 below it.
Further, described support plate 7 side is provided with connecting rod 10, and described connecting rod 10 is driven by lower hydraulic cylinder 11.
Further, described slide block 8 is connected by feather key 12 with support plate 7.
Further, described upper jacking block 5 is driven by upper hydraulic cylinder 13.
Further, described support plate 7, slide block 8, eccentric wheel 9 by a gland by 14 its be limited in the cavity of base 3 inside, gland 14 has the groove 15 moved up and down for connecting rod 10.
Further, described connecting rod 10 has two, and connecting rod 10 one end is connected on support plate 7, and the other end connects top board 16, connects lower hydraulic cylinder 11 below top board 16.
In use during heart frame secondary process, moved to appropriate location, pressing plate locking is carried out position and is fixed.Open centre frame upper bracket 1, hanging in workpiece wouldn't loose lifting rope.Unclamp eccentric wheel 9, use lower hydraulic cylinder 11 to be embedded on rest pad 7 by top board 16 and connecting rod 10 fast servo support plate 7, two lower jacking blocks 6, while lower jacking block 6 rises, rotating shaft 17 keeps eccentric wheel 9, slide block 8, the contact of each of support plate 7; Be Cylindrical Surfaces Contact between eccentric wheel 9 and slide block 8, contact area is large, and supporting rigidity is strong; That key connects between slide block 8 and support plate 7, can along the direction relative sliding of feather key 12.When two lower jacking blocks 6 are with absorption surface, unclamp lifting rope, close centre frame upper bracket 1.Eccentric stiffener carries out accurate adjustment, and the pivot of the bearing center and workpiece that reach centre frame overlaps, and then locks eccentric stiffener.Upper jacking block 5 drives rapid clamping by upper hydraulic cylinder 13.Complete back work, the manufacturing procedure of workpiece can be carried out.
All these eccentric stiffeners are all be assemblied in the cavity in the base 3 of centre frame, and gland 14 pairs of slide blocks 8 and support plate 7 play the role of positioning, between contact surface slidably.Work pieces process completes, and upper hydraulic cylinder 13 drives upper jacking block 5 of retracting rapidly, opens centre frame upper body, hangs out workpiece.
