Abstract
A self-centering manual hydraulic clamp device belongs to the technical field of mechanical manufacture and comprises a chuck seat, a tension and compression chuck, a hydraulic device, a pull rod, a return spring, lever gears, a sliding rack, a stress pull block and a jaw block, wherein the hydraulic device is mounted in the chuck seat; a piston of the hydraulic device is connected with the pull rod; three lever gears are mounted on the tension and compression chuck; lever heads of the lever gears are arranged in clamping grooves at the top end of the pull rod; a sliding chute is formed on the upper surface of the tension and compression chuck; the sliding rack is mounted in the sliding chute; teeth at the tail parts of the lever gears are meshed with corresponding teeth of the sliding rack; and the stress pull block and the jaw block are mounted on the sliding rack. When the self-centering manual hydraulic clamp device works, a workpiece to be processed is placed in the jaw block, the hydraulic device is started and the workpiece to be processed is clamped by using a part driving jaw block. The self-centering manual hydraulic clamp device disclosed by the utility model can be self-centered and is firmly fixed and is simple for operation.
Description
Technical field
The utility model belongs to machinery manufacturing technology field, relates to a kind of anchor clamps.
Background technology
At present, the anchor clamps that are used for machining have scroll chuck, three-jaw wedge-type chuck etc.; It is exactly that fastener is insecure that all there is a drawback in these chucks; Owe power, adopt pneumatic or mechanical-hydraulic like three-jaw wedge-type chuck, though the operation smooth operation is easy; High efficiency, but just owed power for strong load operation.Its reason is that wedge becomes the inclined-plane with the wedge groove, the horizontal body of wedge in the chute of chuck, when drift when drop-down; Under the gravitation on inclined-plane, the horizontal body of wedge moves in laterally in the chute of chuck, at this moment wedge in the wedge groove above internal friction; Below outer friction; The then top mill anterior angle of the horizontal body of wedge is ground relief angle below, and pulling force major part pneumatic or that hydraulic pressure produces is disappeared on these rubbing surfaces.
Scroll chuck can only turn cingulum moving big basin tooth in little angle only according to people's hand-power; Make flat thread drive claw expert or layman in chute again, this messenger's hand-power is very limited and affact this limited strength on the workpiece of scroll chuck and need overcome frictional force layer by layer.Promptly require great effort with scroll chuck, time-consuming again, not can adapt to sequencing production in enormous quantities.Moreover the frequent card engaging workpiece of scroll chuck, the chuck internal works is worn the most easily, and its service life is not long.
Summary of the invention
The technical problem that the utility model will solve provides a kind of easy to operate, fixed self-centering hand-hydraulic grip device.
The scheme of the utility model technical solution problem is to adopt chuck seat, tension and compression chuck, hydraulic means, pull bar, return spring, lever and gear wheel, sliding rack, stress pulling block and rest shoe to constitute self-centering hand-hydraulic grip device, and the tension and compression chuck is installed on the chuck seat, and hydraulic means is housed in the chuck seat; The piston cylinder lever connecting rod of hydraulic means, the top of pull bar have three draw-in grooves that are 120 degree angles, and return spring is installed on the pull bar; Three lever and gear wheels are installed on the tension and compression chuck; Three lever and gear wheels are 120 degree angles respectively at grade, and the lever head of each lever and gear wheel is respectively in a draw-in groove; Tension and compression chuck upper surface has three chutes that are 120 degree angles; Three chutes with the axle center of tension and compression chuck be central point radially, three sliding racks are installed in respectively in the chute of a correspondence, the tooth engagement of the tooth of lever and gear wheel afterbody and corresponding sliding rack; A stress pulling block is installed on each sliding rack, a rest shoe is housed on each stress pulling block.During work, workpiece is placed in the rest shoe, the primer fluid pressure device, piston drives pull bar and moves downward; Draw-in groove depress lever head, the tooth of lever and gear wheel afterbody drives sliding rack and moves to the axis direction of tension and compression chuck, and sliding rack drives the stress pulling block and rest shoe moves to the axis direction of tension and compression chuck; Rest shoe is accomplished the clamping to workpiece, after the completion of processing, controls hydraulic means; Hydraulic oil is refluxed, and pull bar is return under the effect of return spring, and drives other parts return.Can change different rest shoes for different workpieces.
The utility model can self-centering, and is fixed, simple to operate, durable in use, increases substantially operating efficiency, thoroughly solves the hypodynamic problem of card, adapts to extensive sequencing production.
Description of drawings
Accompanying drawing is the cutaway view of the utility model.
The specific embodiment
The utility model is made up of chuck seat 1, tension and compression chuck 2, hydraulic means 3, pull bar 5, return spring 7, lever and gear wheel 8, sliding rack 10, stress pulling block 12 and rest shoe 13, and tension and compression chuck 2 is installed on the chuck seat 1, and hydraulic means 3 is housed in the chuck seat 1; Piston 4 cylinder lever connecting rods 5 of hydraulic means 3, there are three draw-in grooves 6 that are 120 degree angles on the top of pull bar 5, and return spring 7 is installed on the pull bar 5; Three lever and gear wheels 8 are installed on the tension and compression chuck 2; Three lever and gear wheels 8 are 120 degree angles respectively at grade, and the lever head 9 of each lever and gear wheel 8 is respectively in a draw-in groove 6; Tension and compression chuck 2 upper surfaces have three chutes 11 that are 120 degree angles; Three chutes 11 with the axle center of tension and compression chuck 2 be central point radially, three sliding racks 10 are installed in respectively in the chute 11 of a correspondence, the tooth engagement of the tooth of lever and gear wheel 8 afterbodys and corresponding sliding rack 10; A stress pulling block 12 is installed on each sliding rack 10, a rest shoe 13 is housed on each stress pulling block 12.
