Abstract
The invention relates to a swinger clamping device comprising a support. A cylinder and a pressure bar which is used for compressing a workpiece are fixed on the support. A gear is also hinged to the support. A piston rod of the cylinder is hinged to the gear. A horizontal rack meshes with the gear and is fixed on the support through two bearings. The tail end of the rack is hinged to the compressing end of the pressure bar through a link. A swing bar is also hinged to the support. The free end of the swing bar is hinged to the rack. When compressed, the swing bar and the link are collinear. The swing bar and the link in the swinger clamping device form a toggle swinger clamping mechanism. When the swinger clamping device is in the state of clamping, the swing bar and the link are collinear, and meanwhile, the work piece being compressed can experience high compressing force, acting forces of the work piece to the link and the swing bar both pass hinge points of the rack, so that no rotational torque exists, rotation of the device is avoided and the work piece can be stably clamped.
Description
Technical field
The present invention relates to a kind of fixture of machining, be specifically related to a kind of swing clamping device.
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 unclamping at a slow speed.And the piston mandril of cylinder is to rely on air pressure to carry out jacking, cannot produce huge thrust, when needing hold down gag to improve larger pressure, be often difficult to accomplish.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of swing clamping device, 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, technical scheme of the present invention 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 during 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 when 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.
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 that the present invention swings clamping device embodiment.
The specific embodiment
As shown in Figure 1, the present invention 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 during 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.
During use, adopted above-mentioned clamping structure, formed toggle and swing clamp mechanism.Particularly when 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 the active force of 5 pairs of connecting rods 4 of workpiece and fork 3 all passes through pin joint, 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 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.
