Abstract
The utility model discloses an eccentric gear hydraulic clamp and relates to the technical field of clamping equipment. The eccentric gear hydraulic clamp comprises a clamping jaw, a guiding plate, a guiding rail, two eccentric wheels, drive rods and a hydraulic cylinder. Two pistons are arranged in the hydraulic cylinder. The portion between each piston and one side wall of the hydraulic cylinder is respectively provided with one of two springs. The middle of each piston is respectively provided with an axial hole. A ball head is arranged in each axial hole and connected with one end of each drive rod. The other end of each drive rod is hinged with each eccentric wheel. Each eccentric wheel is installed in an oval groove formed in the guiding plate. Each oval groove is perpendicular to each axial hole in the length direction. The guiding plate is connected with the guiding rail in a sliding mode. The lower end of the guiding plate is connected with the clamping jaw through a bolt. The eccentric gear hydraulic clamp overcomes the shortages of complex structure and operation and improves machining efficiency.
Description
Technical field
The utility model relates to the clamping device technical field, particularly a kind of eccentric wheel hydraulically operated fixture.
Background technology
Along with the raising day by day of engineering goods precision, certainly will the corresponding required precision that has improved anchor clamps.Anchor clamps are mainly used to reduce the time of workpiece processing, to raise labour productivity, alleviate working strength of workers, but common high efficiency anchor clamps have automation anchor clamps, high speed anchor clamps and have the anchor clamps etc. of clamping force device, and structure is too complicated, and the more complicated that operates, not only can not reduce the time of processing, also increase working strength of workers, do not satisfied the demand of high accuracy clamping and positioning, reduced production efficiency.
The utility model content
The utility model provides an axial workpiece hydraulically operated fixture simple in structure, simple to operate.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme: a kind of eccentric wheel hydraulically operated fixture, comprise jaw, guide plate, guide rail, two eccentric wheels, drive rod, hydraulic cylinder, be provided with two pistons in the described hydraulic cylinder, be provided with two springs between the sidewall of described piston and hydraulic cylinder, two middle of piston offer axial hole respectively, be provided with bulb in the described axial hole, bulb is connected with an end of drive rod, the other end and eccentric wheel are hinged, described eccentric wheel is installed in the oval groove of offering on the guide plate, and guide plate and guide rail are slidingly connected, and the lower end of described guide plate is connected by bolt with jaw.
Described axial hole is vertical with the oval groove length direction.
Beneficial effect: the utility model eccentric wheel hydraulically operated fixture, make double-piston move by the hydraulic fluid pressure in the hydraulic cylinder, thereby two eccentric wheels of the spin drive installation in the piston in the oval groove that guide plate is offered are synchronized with the movement, the jaw that is connected with guide plate is clamped workpiece, simple in structure, with the power output of hydraulic means as anchor clamps, again by spin, drive rod, the eccentric kind of drive, make that friction loss is few and output is big, clamping work pieces firmly, reliably.
Description of drawings
Fig. 1 is the schematic diagram of a kind of eccentric wheel hydraulically operated fixture of the utility model embodiment.
The specific embodiment
Shown in Fig. 1, the utility model eccentric wheel hydraulically operated fixture, comprise jaw 2, guide plate 3, guide rail 4, two eccentric wheels 5, drive rod 7, hydraulic cylinder 6, be provided with two pistons 9 in the hydraulic cylinder 6, be provided with two springs 8 between the sidewall of described piston 9 and hydraulic cylinder 6, the middle part of two pistons 9 offers axial hole 10 respectively, be provided with bulb 11 in the described axial hole 10, bulb 11 is connected with the upper end of drive rod 7, the lower end of drive rod 7 and eccentric wheel 5 are hinged, two eccentric wheels 5 are installed in the oval groove of offering on the guide plate 3, oval groove is vertical with axial hole 10 both length directions, guide plate 3 is slidingly connected with guide rail 4, the lower end of described guide plate 3 is connected by bolt 12 with jaw 2, added hydraulic oil between two pistons 9, under the driving of hydraulic means, two pistons 9 begin expansion under the effect of hydraulic fluid pressure, the bulb 11 that is provided with in the axial hole is to lower slider, two eccentric wheels 5 that the drive rod 7 that is connected with bulb 11 drives in the guide plate 3 rotate, make guide plate 3 on guide rail 4 to lower slider, the jaw 2 that is connected with guide plate 3 at last moves down workpiece 1 clamping and positioning.
Above-described only is preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not influence effect and practical applicability that the utility model is implemented.
