The specific embodiment
Further introduce embodiments of the invention below in conjunction with accompanying drawing.
Referring to Fig. 1, Fig. 2, Fig. 3.This hydraulic clamp turnover machine comprises mould turnover clamping device 1, crossbeam track 2 and lifting balancing device 3.Crossbeam track 2 is clipped between the 1h of directive wheel up and down of mould turnover clamping device 1, and lifting balancing device 3 is fixed on the top, middle part of crossbeam track 2.
Mould turnover clamping device 1 comprises left clamp arm 1a, right clamp arm 1b, left gear tooth bar swing upset hydraulic cylinder 1c, right gear tooth bar swing upset hydraulic cylinder 1d, left returning face plate 1e, right returning face plate 1f and clamping hydraulic cylinder 1g.Left side clamp arm 1a, right clamp arm 1b axisymmetricly, the two top is respectively equipped with each two directive wheel 1h up and down, left clamp arm 1a is provided with journal stirrup 1i, right clamp arm 1b is provided with journal stirrup 1j; The tail end of clamping hydraulic cylinder 1g is connected on the left clamp arm 1a by journal stirrup 1i with bearing pin, and clamping hydraulic cylinder 1g piston rod front end is connected on the right clamp arm 1b by journal stirrup 1j with bearing pin; Left gear tooth bar swing upset hydraulic cylinder 1c is by being bolted to the bottom of left clamp arm 1a, right gear tooth bar swing upset hydraulic cylinder 1d is by being bolted to the bottom of right clamp arm 1b, and left gear tooth bar swing upset hydraulic cylinder 1c is relative with the output shaft of right gear tooth bar swing upset hydraulic cylinder 1d; The output axle head is fixed left returning face plate 1e and right returning face plate 1f respectively.
Crossbeam track 2 comprises left sprocket wheel 2a, right sprocket wheel 2b, chain 2c, back adjusting lever 2d, preceding adjusting lever 2e and track main body 2f.Left side sprocket wheel 2a, right sprocket wheel 2b are separately fixed at the two ends of track main body 2f, chain 2c walks around left sprocket wheel 2a and right sprocket wheel 2b, the end of chain 2c is connected the end of back adjusting lever 2d by bearing pin, the other end of back adjusting lever 2d is fixed on the left clamp arm 1a, the end of adjusting lever 2e before the other end of chain 2c is connected by bearing pin, the other end of preceding adjusting lever 2e is fixed on the right clamp arm 1b.
Lifting balancing device 3 comprises connector 3a, hydraulic cylinder 3b, lifting body 3c and roller set 3d.Roller set 3d is bearing on the lifting body 3c, be processed with the chute track on the connector 3a, two rollers about roller set 3d comprises, the roller shaft of roller are by the diaxon bearing supporting that is installed on the lifting body, and the roller two ends embed in the set chute track of connector 3a front and back connecting plate.The cylinder body of hydraulic cylinder 3b is fixed on the connector 3a, and the front end piston rod of hydraulic cylinder 3b is by being threaded on the lifting body 3c; Connector 3a is by being bolted on the crossbeam track 2.
The operation principle of this hydraulic clamp turnover machine: utilize shop traveller or other lifting device, hang the lifting balancing device of this hydraulic clamp turnover machine, move to the sand mold or the sandbox place that want mould turnover, when clamping hydraulic cylinder 1g piston rod is stretched out, the right clamp arm 1b that links to each other with the piston rod front end produces shift action, clamping hydraulic cylinder 1g then moves to the rightabout that piston rod stretches out simultaneously, the rightabout motion that the left clamp arm 1a that is connected with the tail end of clamping hydraulic cylinder 1g also stretches out to piston rod simultaneously, this moment, the two ends owing to chain 2c were separately fixed on left clamp arm 1a and the right clamp arm 1b, and chain 2c walks around on left sprocket wheel 2a and the right sprocket wheel 2b, this just forces left clamp arm 1a and right clamp arm 1b outwards to move along the crossbeam track simultaneously, finishes and unclamps action; When the piston rod of clamping hydraulic cylinder 1g is withdrawn, then produce the clamping action of clamp arm.For sand mold or the sandbox that clamps different size, the folding size of clamp arm can be adjusted automatically according to sand mold or sandbox.When turnover machine is finished the action that clamps sand mold or sandbox, because the sand mold of different size or the center of gravity difference of sandbox, can make this hydraulic clamp turnover machine generation inclination in various degree, the piston rod that drive the hydraulic cylinder 3b on the lifting balancing device 3 this moment stretches out or withdrawal can make lifting body 3c produce displacement with respect to connector 3a, makes equipment reach balance again thereby change the lifting position.Behind balance of plant, left gear tooth bar swing upset hydraulic cylinder 1c and right gear tooth bar swing upset hydraulic cylinder 1d drive respectively turn over left-hand rotation plate 1e and right returning face plate 1f drive sand mold or sandbox in the same way Rotate 180 ° finish the mould turnover action; Clamping hydraulic cylinder 1g piston rod stretches out, and unclamps sand mold or sandbox.
In conjunction with the accompanying drawings the preferred embodiment for the present invention has been done detailed description above, but the present invention is not limited to above-mentioned embodiment, in the ken that those of ordinary skills possessed, can also under the prerequisite that does not break away from aim of the present invention, make various equivalent variations.
