Abstract
The utility model discloses a hydraulic clamping mechanism which comprises a machine base, an oil cylinder, a piston, a clamping claw and a force applying rod, wherein the clamping claw and the force applying rod are connected on the machine base in a hinged mode, the force applying rod is connected with the piston, a reset spring is connected between the piston and the machine base, a shaft ring is arranged on the force applying rod and is connected with a connection rod, a rocker-slider four-bar mechanism is formed by the connection rod, the force applying rod and the clamping claw, and the driven end of the clamping claw is used for tightly compressing a workpiece. The hydraulic clamping mechanism is simple in structure, and clamping and loosening of the workpiece can be achieved by injection and extraction of pressurized fluid in the oil cylinder in an operation process.
Description
Technical field
The utility model belongs to mechanical field, is specifically related to a kind of hydraulic clamp mechanism.
Background technology
Arrestment mechanism is to have to make moving component or movable machinery slow down, stop or keeping the device of 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 detent position, apparatus to running applies the external force opposite with operating 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 (as mine hoist, elevator etc.) then is installed near on the slow-speed shaft of equipment working portion.
Mechanical operating part is stopped or slowing down the moment of resistance that must apply be called braking moment.Braking moment is design, selects the foundation of brake for use that its size is determined by pattern and the job requirement of machinery.The performance of used friction material directly influences braking procedure on the brake, and the principal element that influences its performance is operating temperature and temperature rise speed.Friction material should possess high and stable coefficient of friction and good wearability.
The utility model content
The technical problems to be solved in the utility model provides hydraulic clamp mechanism a kind of simple in structure, easy to operate.
In order to solve the problems of the technologies described above, the utility model provides a kind of hydraulic clamp 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 constitute rocker slider four-bar mechanism, the driven end workpiece pressing of jaw.
During workpiece pressing, inject pressure fluid in oil cylinder, drive force application rod and slide thereby promote the piston motion, 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, and makes 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 utility model 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
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model embodiment.
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 of placing 3 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 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 can not influence effect and practical applicability that the utility model is implemented.
