Abstract
The utility model relates to a clamping mechanism for a tubular column part, in particular to a self-centering hydraulic clamping device for the tubular column part. The self-centering hydraulic clamping device for the tubular column part mainly comprises a loop, a clamp body, rotation supports, copper sliding plates, connecting rods, claw bodies, sliding sleeves and claws. According to the self-centering hydraulic clamping device for the tubular column part, five claws are adopted and are evenly distributed for 360 degrees in the peripheral direction; self centering can be realized by the circular arc design of the surfaces of the claws, which are contacted with the workpiece. Moreover, the clamping force is even; not only can the workpiece be firmly clamped but also the phenomenon that the surface of the workpiece is jammed because the clamping force is excessive can be prevented.
Description
Technical field
The utility model relates to the clamp mechanism of tubing string spare, is specially a kind of self-centering hydraulic pressure pipe fitting cramping arrangement.
Background technology
In recent years new forms of energy nuclear power, wind power plant fast development, the part dimension of device equipment is larger, do not allow to clamp distortion, but also will guarantee the reliability of armoring location in the process, do not affect 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 purpose of this utility model is for the problems referred to above, and a kind of convenient mounting and clamping is provided, 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 pressure tubing string spare 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, the left end in week has placed clamp body in the ring set, 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 by revolution and is connected with ring set, and the right-hand member of force transfer body evenly is hinged in the circumferential direction of the circle 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, the 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 have been bolted respectively claw towards an end of ring set axial centre, and the surface that claw contacts with workpiece is circular arc.
The utility model self-centering hydraulic pressure tubing string spare clamping device can make workpiece carry out angle and rotate freely, and processes on can be arbitrarily angled to the circumference of workpiece.
The utility model adopts five claws and 360 degree are uniform in a circumferential direction, the designed arc-shaped appearance of claw and workpiece contact surface can be realized self-centering, cut clamping force even, clamping work pieces firmly not only can prevent from again crushing because clamping force is excessive surface of the work.
The utility model 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.

The specific embodiment
Shown in shown in Fig. 1-5, the utility model mainly is comprised 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 1 interior week of ring set has placed clamp body 2, the left end of clamp body 2 is connected with and drives the drive unit 13 that clamp body rotates, be provided with force transfer body 3 between the interior week of the periphery of clamp body 2 and ring set 1, be 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 by revolution is connected connections with ring set, the right-hand member of force transfer body 3 in the circumferential direction of the circle evenly hinge be connected to five connecting rods 6.
The right-hand member in 1 interior week of ring set is fixedly connected with claw guiding 5, 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 is wedge shape with catching body 8, 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 have been bolted respectively claw 10 towards an end of ring set axial centre, and the surface that claw 10 contacts with workpiece is 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 by 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 by force transfer body 3, supports 4 by revolution sliding sleeve 9 is not rotated, and can drive the rotation of jaw body 8 and claw 10 by connecting rod 6, thereby finish various machineds.
