Abstract
The invention relates to a clamping device and specifically relates to a double-arm single-action hinge clamping device. The double-arm single-action hinge clamping device comprises a base, a pressing plate with a clamping head and a cylinder connected to the base, wherein the middle part of the pressing plate is hinged to the base. The double-arm single-action hinge clamping device is further provided with a lower hinge arm, an upper hinge arm, a hinged plate fixed on the base, and a drive rod of which one end is connected with the piston rod of the cylinder, wherein the other end of the drive rod, one end of the upper hinge arm and one end of the lower hinge arm are hinged to one another, the other end of the lower hinge arm is hinged to the hinged plate, and the upper hinge arm is hinged to the end, far away from the clamping head, of the pressing plate.
Description
Technical field
The present invention relates to a kind of clamping device, be specifically related to a kind of both arms single-acting hinge clamping device.
Background technology
On lathe during processing work, all must be by Workpiece clamping, prevent that workpiece is subject to the effect of the external force such as cutting force and moves in process, clamping device is exactly on lathe, to be used for the device of clamping work pieces.Clamping device generally can sub-power source and running part, and power source is for generation of clamping force, and that power source can come from is pneumatic, hydraulic pressure and manpower etc.Running part is clamping force by power-conversion, realizes and clamps action and clamp effect.
Hinge clamping mechanism is to use aborning more a kind of clamp mechanism, and it is simple in structure, and force increasing ratio is large, therefore, take hydraulic pressure or air pressure in the occasion of power, most hinge clamping devices that adopt.Existing hinge clamping device normally cylinder drives the above pressing plate clamping work pieces of 2 or 2 by hinge arms, and during this clamping device holding workpiece, to put on power on workpiece less for single pressing plate, is not suitable for the workpiece of the larger chucking power of requirement.
Summary of the invention
The defect existing for above-mentioned prior art, the object of the present invention is to provide a kind of both arms single-acting hinge clamping device, this clamping device is by pressing plate holding workpiece of air cylinder driven, puts on chucking power on workpiece large, is applicable to require the workpiece of larger chucking power.
For achieving the above object, technical scheme of the present invention is: both arms single-acting hinge clamping device, comprise pedestal, the pressing plate with clamping head and be connected in the cylinder on pedestal, wherein, described pressing plate middle part is articulated with on pedestal, also be provided with lower hinge arms, upper hinge arm, be fixed on the drive link that the articulated slab on pedestal is connected with the piston rod of cylinder with one end, the drive link other end, upper articulated jib one end and lower articulated jib one end three are hinged, the described lower articulated jib other end and articulated slab are hinged, and upper articulated jib and pressing plate clamping head far away one end is hinged.
While adopting technique scheme, the piston rod of cylinder drives drive link, drive link drives lower hinge arms and the upper hinge arm hinged with its one end simultaneously, instantly hinge arms and upper hinge arm are when straight line, pressing plate clamping head far away one end is upwards propped up, pressing plate clamping head one end bottom, by piece-holder.The present invention is by pressing plate holding workpiece of air cylinder driven, puts on chucking power on workpiece large, is applicable to require the workpiece of larger chucking power.
Further, described cylinder is arranged in the cavity that pedestal arranges, and cylinder piston rod far away one end is by being rotationally connected along cylinder connecting axle and pedestal radially.When cylinder piston rod drives drive link, cylinder can swing around connecting axle, and cylinder, in swing process, can be converted into mechanical energy by the potential energy after upper pendulum, and can shock absorbing power.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the structural representation of both arms single-acting hinge clamping device embodiment of the present invention.
The specific embodiment
As shown in Figure 1, a kind of both arms single-acting hinge clamping device, comprise pedestal 1, pressing plate with clamping head 7 and be connected in the cylinder 2 on pedestal 1, cylinder 2 is arranged in the cavity of pedestal 1 setting, cylinder 2 piston rod far away one end are by being rotationally connected with pedestal 1 along cylinder 2 connecting axle 9 radially, wherein, pressing plate 7 middle parts are articulated with on pedestal 1, also be provided with lower hinge arms, upper hinge arm, be fixed on the drive link 3 that the articulated slab 4 on pedestal 1 is connected with the piston rod of cylinder 2 with one end, drive link 3 other ends, upper articulated jib 6 one end and lower articulated jib 5 one end threes are hinged, lower articulated jib 5 other ends and articulated slab 4 are hinged, upper articulated jib 6 is hinged with pressing plate 7 clamping head far away one end.
Concrete using method:
As shown in Figure 1, workpiece 8 to be held is positioned over to clip position, from the air admission hole on cylinder 2 right sides, enter Compressed Gas, Compressed Gas promotes piston and piston rod is moved to the left, and the piston rod of cylinder 2 drives drive link 3 left, and drive link 3 promotes lower hinge arms and the upper hinge arm hinged with its one end left simultaneously, instantly hinge arms and upper hinge arm are when straight line, pressing plate 7 clamping head far away one end are upwards propped up, and pressing plate 7 clamping head one end bottoms, clamp workpiece 8.From the air admission hole in cylinder 2 left sides, enter Compressed Gas, Compressed Gas promotes piston and piston rod moves right, the piston rod of cylinder 2 pulls drive link 3 to the right, drive link 3 pulls the lower hinge arms hinged with its one end and upper hinge arm to the right simultaneously, now, upper articulated jib 6 pulls pressing plate 7 clamping head far away one end bottoms, and pressing plate is put on 7 clamping head one end, and workpiece 8 is unclamped.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; do not departing under the prerequisite of structure of the present invention; can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
Claims (2)
1. both arms single-acting hinge clamping device, comprise pedestal, the pressing plate with clamping head and be connected in the cylinder on pedestal, it is characterized in that, described pressing plate middle part is articulated with on pedestal, also be provided with lower hinge arms, upper hinge arm, be fixed on the drive link that the articulated slab on pedestal is connected with the piston rod of cylinder with one end, the drive link other end, upper articulated jib one end and lower articulated jib one end three are hinged, and the described lower articulated jib other end and articulated slab are hinged, and upper articulated jib and pressing plate clamping head far away one end is hinged.
