Description
Technical field
The utility model relates to a kind of clamping device, is specifically related to a kind of as clamping part to be processed, the hydraulically powered coordinated type grip device of employing on the building-block machine.
Background technology
Widely used various hydraulically operated fixtures on building-block machine at present, most of structures are comparatively complicated, and the part of forming anchor clamps is many, manufacturing is time-consuming, and the assembling and setting process is longer.For the small-sized building-block machine of rotary table formula multistation, owing to will be furnished with the 8-10 sleeve clamp at little panoramic table, if the anchor clamps complexity, then the cost of manufacture of many sleeve clamps is very big especially, installs and also is a problem.Therefore building-block machine has strict requirement to clamp structure, wishes that clamping is reliable, simple in structure, be convenient to Installation and Debugging, cost is low.
Therefore, need a kind of new technical scheme to solve the problems referred to above.
The utility model content
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides a kind of coordinated type grip device, by the clamp arm that arranges of symmetry, makes that clamping is reliable, simple in structure, is convenient to Installation and Debugging.
Technical scheme: for achieving the above object, a kind of coordinated type grip device of the present utility model, comprise clamp body, be positioned at clamp body oil cylinder, be fixed on the pole on the clamp body and be fixed on clamp arm on the pole by hinge, be provided with pair of pistons in the described oil cylinder, described pair of pistons is connected with piston rod respectively, piston rod is connected with clamp arm by bearing pin, and the oil cylinder middle part is provided with fuel feed hole, and the fuel feed hole both sides respectively are provided with a spill port.
Described pole is fixed on the clamp body by holding screw; The both sides of described oil cylinder are provided with end cap.
The vertical central shaft that described clamp body, oil cylinder, piston, piston rod, pole, clamp arm, bearing pin and hinge are with this grip device is the structure of symmetry axis symmetric arrangement.
Coordinated type grip device of the present utility model is a kind of symmetrical structure, when hydraulic oil enters the oil cylinder rear portion from oil-in, two-piston is mobile round about respectively together with piston rod, under piston rod and bearing pin effect, clamp arm rotates around hinge, and the clamp arm front end is pressed on workpiece the upper surface of clamp body to carry out machining.
Beneficial effect: a kind of coordinated type grip device of the present utility model, drive the clamp arm clamping work pieces by the pressure oil driven plunger, adopt symmetrical structure, have advantages such as simple in structure, easily manufactured, that cost is low, assembling and setting is convenient, result of use is good, have good utilization promotional value, be fit to very much adopt in enormous quantities on the building-block machine.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation.
As shown in Figure 1, a kind of coordinated type grip device of the present utility model, comprise clamp body 15, be positioned at the oil cylinder 13 of clamp body 15, be fixed on the pole 1 on the clamp body 15 and be fixed on clamp arm 6 on the pole 1 by hinge 2, be provided with pair of pistons 11 in the oil cylinder 13, pair of pistons 11 is connected with piston rod 8 respectively, piston rod 8 is connected with clamp arm 6 by bearing pin 7, oil cylinder 13 middle parts are provided with fuel feed hole 12, fuel feed hole 12 both sides respectively are provided with a spill port 14, clamp body 15, oil cylinder 13, piston 11, piston rod 8, pole 1, clamp arm 6, the vertical central shaft that bearing pin 7 and hinge 2 are with this grip device is the structure of symmetry axis symmetric arrangement.
In the utility model, pole 1 is fixed on the clamp body 15 by holding screw 5, be provided with end cap 10 in the both sides of oil cylinder 13, bearing pin 7 inserts in the mounting hole of clamp arms 6, the clamping of clamp arm 6 with unclamp action and all promote by the bearing pin 7 that is fixed on piston rod 8 front ends.
A kind of coordinated type grip device of the present utility model, when reality is used, when pressure oil enters the working chamber of oil cylinder 13 by fuel feed hole 12, pressure oil drives left and right sides piston 11 outward directions and moves, piston 11 promotes piston rod 8 and moves, piston rod 8 is connected by bearing pin 7 with clamp arm 6, the mobile clamp arm 6 that promotes of piston rod 8 outwards moves, because clamp arm 6 middle parts are connected with pole 1 by hinge 2, clamp arm 6 can rotate around hinge 2, the front end of each clamp arm 6 moves down simultaneously, reaches the purpose of clamping work pieces 4.
When workpiece 4 has processed, has needed dismounting, pressure oil enters in oil cylinder 13 working chambers by spill port 14, promoting 11 while of left and right sides piston inward direction moves, piston 11 drives piston rod 8 inward directions and moves, thereby driving clamp arm 6 front ends moves up, reach the purpose of unclamping workpiece 4, can take out workpiece 4, reinstall new part.
In the utility model, a plurality of coordinated type grip devices can evenly be installed on the surface of building-block machine panoramic table successively by screw 9.
The above only is preferred embodiment of the present utility model; be noted that for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
