Abstract
The utility model provides a swing clamping device which comprises a bracket, wherein an air cylinder and a compression bar used for compressing a workpiece are fixed on the bracket; a gear is hinged to the bracket; a piston rod of the air cylinder is eccentrically hinged to the gear; a horizontal rack is meshed with the gear; the rack is fixed on the bracket through two bearings; the tail end of the rack is hinged to the compressing end of the compression bar through a connecting rod; a swing link is further hinged to the bracket; the free end of the swing link is hinged to the rack; when in a compressed condition, the swing link and the connecting rod are in a straight line. According to the adoption of the structure of the clamping device, a toggle swing clamping mechanism is formed by the swing link and the connecting rod; particularly in a clamping position, the swing link and the connecting rod are in one straight line, therefore, a huge pressing force is born by the compressed workpiece; moreover, as the acting forces of the workpiece on the connecting rod and the swing link pass through a hinge joint on the rack, the driving torque is avoided, the revolution of the mechanism is avoided and the workpiece is clamped steadily.
Description
Technical field
The utility model relates to a kind of fixture of machining, is specifically related to a kind of clamping device that swings.
Background technology
Cylinder is a kind of common mechanical driver unit, it is fast that it has action, the advantage that continuation is good, weak point is if use the piston rod of cylinder directly to drive clamping device motion, cannot regulate the speed of clamping device in motion process to change, can not effectively complete when needing jogging speed to clamp in machining and unclamp at a slow speed.And the piston mandril of cylinder is to rely on air pressure to carry out jacking, cannot produce huge thrust, in the time needing hold down gag to improve larger pressure, be often difficult to accomplish.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of clamping device that swings, and by the frame for movement of ingenious setting, the piston rod that overcomes cylinder can not produce the shortcoming of larger pressure.
For achieving the above object, the technical solution of the utility model is: swing clamping device, comprise support, on described support, be fixed with the depression bar of cylinder and workpiece pressing, on described support, be also hinged with gear, the piston rod Eccentric-hinge of described cylinder is connected on gear, is engaged with the tooth bar of a level on described gear, and described tooth bar is fixed on support by two bearings; The compression end of the end of described tooth bar and depression bar passes through rod hinge connection; On described support, be also hinged with a fork, the free end of described fork is hinged on tooth bar, and when impaction state, fork and connecting rod are positioned on straight line.
While adopting technique scheme, adopted above-mentioned clamping structure, fork and connecting rod form toggle and swing clamp mechanism.Particularly in the time of clamped position, fork and connecting rod are positioned on straight line, now, workpiece pressing can be participated in very large thrust, and workpiece to the active force of connecting rod and fork all by the pin joint on tooth bar, therefore there is no rotating torque, cannot cause the revolution of mechanism, therefore clamping work pieces stably.Otherwise while unclamping workpiece, piston rod oppositely moves, and then drive the connecting rod and the fork that are positioned on straight line to rotate, can easily throw off workpiece, there is good result of use.
Further, described support vertically arranges, and described cylinder, depression bar, fork, connecting rod are all located at the homonymy of support.
Further, in order to limit the pendulum angle of fork, on described support, be also provided with the block of two restriction fork rotational angles.Further, described fork, the rod hinge connection same position on tooth bar.
Further, described block is provided with pressure sensor.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation that the utility model swings clamping device embodiment.
Detailed description of the invention
As shown in Figure 1, the utility model swings clamping device and comprises support, on described support, be fixed with the depression bar 2 of cylinder 1 and workpiece pressing 5, on described support, be also hinged with gear 11, the piston rod Eccentric-hinge of cylinder 1 is connected on gear 11, on gear 11, be engaged with the tooth bar 12 of a level, tooth bar 12 is fixed on support by two bearings.The compression end of the end of tooth bar 12 and depression bar 2 is hinged by connecting rod 4.On support, be also hinged with a fork 3, the free end of fork 3 is hinged on tooth bar 12, and when impaction state, fork 3 and connecting rod 4 are positioned on straight line.In addition, in order to limit the pendulum angle of fork 3, on support, be also fixed with the block 31 of two restriction fork 3 rotational angles.Block 31 is provided with pressure sensor.Can realize Automatic-clamping by the automatic telescopic of measurement data control cylinder.
When use, adopt above-mentioned clamping structure, formed toggle and swing clamp mechanism.Particularly in the time of clamped position, fork 3 and connecting rod 4 are positioned on straight line, now, workpiece pressing 5 can be participated in very large thrust, and workpiece 5 all passes through pin joint to the active force of connecting rod 4 and fork 3, therefore there is no rotating torque, cannot cause the revolution of mechanism, therefore clamping work pieces 5 stably.Otherwise while unclamping workpiece 5, piston rod oppositely moves, and then drive the connecting rod 4 and the fork 3 that are positioned on straight line to rotate, because the arm of force is longer, can easily throw off workpiece, there is good result of use.
Above-described is only preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; do not departing under the prerequisite of 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 affect effect and practical applicability that the utility model is implemented.
