Abstract
The invention discloses a self-centering clamping device for a hydraulic tubular column component and relates to a clamping mechanism of the tubular column component. The self-centering clamping device mainly comprises a ring sleeve, a clamping tool body, a power transmitting body, a rotating support, a clamping jaw guider, a copper slide plate, a connecting rod, a clamping jaw body, a slide sleeve and clamping jaws. Five clamping jaws are uniformly arranged in the peripheral direction at 360 degrees, due to the design of circular arcs on the contact surfaces between the clamping jaws and a workpiece, self-centering can be realized, the workpiece can be firmly clamped, and the surface of the workpiece can be prevented from being damaged by over high clamping force.
Description
Technical field
The present invention relates to the clamp mechanism of tubing string spare, be specially a kind of self-centering hydraulic tube piece clamping device.
Background technology
New forms of energy nuclear power, wind power plant fast development in recent years; The part dimension of device equipment is bigger; Do not allow to clamp distortion, but also will guarantee the reliability of armoring location in the process, do not influence form accuracy, dimensional accuracy and the surface quality etc. of part.Present common clamping device clamps difficulty, working (machining) efficiency is low.
Summary of the invention
The objective of the invention is provides a kind of convenient mounting and clamping to the problems referred to above, be out of shape little, the hydraulic self-centering clamping device of having good positioning.
The technical scheme that realizes above-mentioned purpose is: self-centering hydraulic tube column piece clamping device is characterized in that: mainly comprise ring set, clamp body, force transfer body, revolution support, claw guiding, connecting rod, copper shoe, jaw body, sliding sleeve and claw;
The periphery of ring set is fixedly connected with connector; Connector links to each other with the fluid pressure drive device that drives the ring set move left and right, and the left end in week has placed clamp body in the ring set, and the left end of clamp body is connected with and drives the drive unit that clamp body rotates; Be provided with force transfer body between the interior week of the periphery of clamp body and ring set; Be provided with sliding sleeve between the interior week of force transfer body and the clamp body, the periphery of force transfer body supports through revolution and is connected with ring set, and the right-hand member of force transfer body along the circumferential direction evenly is hinged and is connected to five connecting rods;
The right-hand member in week is fixedly connected with the claw guiding in the ring set; Claw guiding be distributed with five jaw body that match with five connecting rods of force transfer body right-hand member interior week, be provided with copper shoe between claw guiding and the jaw body, the claw guiding is wedge shape with the catching body; The beveled end of claw guiding is towards the axial centre of ring set; Claw guiding is relative with the beveled end of catching body, the narrow end of claw guiding and catching body in the opposite direction, the left end of jaw body and the right-hand member of connecting rod are hinged; Five jaw body are connected with claw through bolt respectively towards an end of ring set axial centre, and the surface that claw contacts with workpiece is a circular arc.
Self-centering hydraulic tube column piece clamping device of the present invention can make workpiece carry out angle and rotate freely, and processes on can be to the circumference of workpiece arbitrarily angled.
The present invention adopt five claws and in a circumferential direction 360 degree be uniformly distributed with, the design of the circular arc of claw and workpiece contact surface can be realized self-centering, it is even to cut clamping force, clamping work pieces firmly not only can prevent to crush because of clamping force is excessive surface of the work again.
The present invention adopts hydraulic clamp, and is not only easy to operate, and replaceable claw inner surface configuration makes it identical with the workpiece shape, thus stressed even, indeformable, have good positioning.
In a word, this fixture operation is convenient, and automaticity is high, and convenient mounting and clamping is had good positioning, and can realize high accuracy, mass production.
Description of drawings
Fig. 1 is a front view of the present invention;
Fig. 2 is that the A-A of Fig. 1 is to cutaway view;
Fig. 3 is a vertical view of the present invention;
Fig. 4 is the vertical view of claw;
Fig. 5 be Fig. 4 B-B to cutaway view.
The specific embodiment
Shown in shown in Fig. 1-5, the present invention mainly is made up of ring set 1, clamp body 2, force transfer body 3, revolution support 4, claw guiding 5, connecting rod 6, copper shoe 7, jaw body 8, sliding sleeve 9 and claw 10.
The periphery of ring set 1 is fixedly connected with connector 11; Connector 11 links to each other with the fluid pressure drive device 12 that drives the ring set move left and right; The left end in week has placed clamp body 2 in the ring set 1; The left end of clamp body 2 is connected with and drives the drive unit 13 that clamp body rotates, and is provided with force transfer body 3 between the interior week of the periphery of clamp body 2 and ring set 1, is provided with sliding sleeve 9 between the interior week of force transfer body 3 and the clamp body 2; The periphery of force transfer body 3 supports 4 through revolution and is connected with ring set 1, the right-hand member of force transfer body 3 along the circumferential direction evenly hinge be connected to five connecting rods 6.
The right-hand member in week is fixedly connected with claw guiding 5 in the ring set 1; Claw guiding 5 be distributed with five jaw body 8 that match with five connecting rods 6 of force transfer body 3 right-hand members interior week, be provided with copper shoe 7 between claw guiding 5 and the jaw body 8, claw guiding 5 and catching body 8 are wedge shape; The beveled end of claw guiding 5 is towards the axial centre of ring set 1; Claw guiding 5 is relative with the beveled end of catching body 8, the narrow end of claw guiding 5 and catching body 8 in the opposite direction, the right-hand member of the left end of jaw body 8 and connecting rod 6 is hinged; Five jaw body 8 are connected with claw 10 through bolt respectively towards an end of ring set axial centre, and the surface that claw 10 contacts with workpiece is a circular arc.
Operation principle:
Fluid pressure drive device 12 drives sliding sleeve 9 and horizontally slips, and sliding sleeve 9 drives force transfer body 3 and horizontally slips, and force transfer body 3 drives claw 10 through connecting rod 6 and horizontally slips along claw guiding 5, thereby realizes opening and degree of tightness of claw 10.
When drive unit 13 drive clamp bodies 2 rotated, clamp body 2 connected revolution support 4 and connecting rod 6 through force transfer body 3, supports 4 through revolution ring set 9 is not rotated, and can drive the rotation of jaw body 8 and claw 10 through connecting rod 6, thereby accomplish various machineds.
