Abstract
The invention discloses a hydraulic clamping mechanism which comprises an engine base, an oil cylinder, a piston, a clamping jaw hinged on the engine base and a force application rod. The force application rod is connected with the piston; a return spring is connected between the piston and a base; the force application rod is provided with a shaft collar; the shaft collar is connected with a connecting rod; a rocker and sliding block four-bar mechanism is formed by the connecting rod, the force application rod and the clamping jaw; and the driven end of the clamping jaw presses a workpiece. The hydraulic clamping mechanism has a simple structure; and in the operating process of the hydraulic clamping mechanism, clamping and loosening on the workpiece can be implemented only by injecting and pumping out pressurized fluid in the oil cylinder.
Description
Technical field
The invention belongs to mechanical field, be specifically related to a kind of Hydraulic Clamping Mechanism.
Background technology
Arrestment mechanism is to have to make moving component or movable machinery slow down, stop or keeping the device of the functions such as halted state, is the machine components that make the movement parts in the machinery stop or slowing down, and is commonly called as brake, lock; Arrestment mechanism applies certain active force by outer bound pair braking parts position, apparatus to running applies and the external force that operates opposite direction, utilize non-rotating element and stop the trend of rotation or the rotation of wheel with phase mutual friction between the spinner member, thereby it is carried out to a certain degree forced brake.Usually be contained on the high speed shaft of equipment in order to reduce a braking moment and structure cun brake, but the main equipment higher to security requirement (such as mine hoist, elevator etc.) then is installed near on the slow-speed shaft of equipment working portion.
Mechanical operating part is stopped or the moment of resistance that must apply of slowing down is called braking moment.Braking moment is design, selects the foundation of brake that its size is determined by pattern and the job requirement of machinery.The performance of used friction material directly affects braking procedure on the brake, and the principal element that affects its performance is operating temperature and temperature rise speed.Friction material should possess high and stable coefficient of friction and good wearability.
Summary of the invention
The technical problem to be solved in the present invention provides Hydraulic Clamping Mechanism a kind of simple in structure, easy to operate.
In order to solve the problems of the technologies described above, the invention provides a kind of Hydraulic Clamping Mechanism, comprise support, oil cylinder, piston, be hinged on jaw and force application rod on the support, force application rod is connected with piston, be connected with back-moving spring between piston and the base, force application rod is provided with the axle collar, and the axle collar is connected with connecting rod, connecting rod, force application rod and jaw consist of rocker slider four-bar mechanism, the driven end workpiece pressing of jaw.
During workpiece pressing, inject pressure fluid in oil cylinder, slide thereby the pushing piston motion drives force application rod, force application rod is as the power source of rocker slider four-bar mechanism, and the slip of force application rod drives jaw and rotates, so that the driven end workpiece pressing of jaw; In the time of need unclamping, extract in-oil cylinder fluid out, piston motion in the other direction under action of reset spring retracts force application rod, and the driven end that drives jaw breaks away from workpiece.Of the present invention simple in structure, only need in the operating process in-oil cylinder pressure fluid injected and extract out just can realize the clamping of workpiece and unclamp.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments:
Fig. 1 is the structural representation of the embodiment of the invention.
The specific embodiment
As shown in Figure 1, pressure fluid is injected into the right ventricle of oil cylinder 7, piston 9 will be moved to the left, clamping force reaches jaw 2 by sheet spring 4, and an end of sheet spring 4 is fixed on the jaw 2, and the other end curves in the endless groove that ring-type hangs over the axle collar 1, the axle collar 1 is contained on the piston rod 6, jaw 2 has 8, and its stage casing all is hinged on the support 5 and turns round centered by fixed axis, and the workpiece 3 of placing is clamped.After pressure fluid in the oil cylinder 7 flowed out, the restoring force of spring 8 moved right piston 9, unclamps workpiece 3.
Above-described only is preferred embodiment of the present invention, should be understood that for a person skilled in the art, under the prerequisite that does not break away from structure of the present invention, can also make some distortion and improvement, these can not affect effect of the invention process and practical applicability.
