Detailed description of the invention
Combine accompanying drawing below by detailed description of the invention the application is described in further detail.
Accurate chuck given by the present embodiment is as it is shown in figure 1, include retainer ring 4, guide ring 1, and arranges with fixing Screw thread rotating disk 3, card lobe 2 and worm screw 5 between ring 4 and guide ring 1.Retainer ring 4 inner periphery is formed with annular housing, screw thread rotating disk 3 are contained in this cavity, and can rotate in cavity.Retainer ring 4 is formed with annular edge 41 away from the side inwall of guide ring 1, Annular edge 41 radially-inwardly stretches along retainer ring so that retainer ring 4 presents one end diameter towards guide ring 1 more than deviating from guiding One end of ring 1;Retainer ring 4 is provided with multiple fixing ear 42 axially extended towards the sidewall of a side opening of guide ring 1, adjacent Accommodating a described card lobe 2 between two fixing ears 42, fixing ear 42 is fixing with guide ring 1 to be connected.Specifically, fixing ear 42 court Be provided with the first screw 421 to a side end face of guide ring 1, guide ring 1 side surface is provided with second corresponding with the first screw 421 Screw 11, during assembling, is screwed fixing bolt by the second screw 11 to the first screw 421 and can realize retainer ring 4 and guide ring 1 Fixing connection.
Further, as shown in Figures 1 and 2, cylindrically, its both ends of the surface are annular to screw thread rotating disk 3, and side is cylinder Shape surface, the side of screw thread rotating disk 3 is formed with the radially-arranged first pretension screw thread 31 of helical pitch direction threadingly rotating disk 3, and first Pretension screw thread 31 is outwards distributed by the side radially from coil to coil of screw thread rotating disk 3 annular.Screw thread rotating disk 3 outer surface is formed with gear Structure 33, this gear structure 33 threadingly rotating disk 3 circle distribution one is enclosed.Retainer ring 4 outer circumference surface is provided with and screw thread rotating disk 3 phase Adaptive worm screw 5, worm screw 5 surface is axially distributed threaded area 52.Surface, threaded area 52 is provided with and is meshed with gear structure 33 Screw thread, so, screw thread rotating disk 3 and worm screw 5 just constitute turbine and worm drive mechanism.Retainer ring 4 outer circumference surface is provided with For fixing the bearing holder (housing, cover) 51 of worm screw 5.Worm screw 5 is distributed gear structure 33 phase of threaded one end and screw thread rotating disk 3 excircle Engagement, threadless one end is suitable with bearing holder (housing, cover) 51, serves as the rotating shaft that worm screw 5 rotates.The end, one end of worm screw 5 be provided with for The operating portion screwed, this operating portion mainly can be easy to screw worm screw 5, in the present embodiment, operating portion to present various structures form For nut structure.Bearing holder (housing, cover) 51 and the side of retainer ring surface foundation be provided with for worm screw 5 screwed one section expose open Window so that worm screw 5 is meshed through this gear structure 33 windowed with screw thread rotating disk 3 excircle.
As shown in Figures 1 and 3, card lobe 2 is arranged between screw thread rotating disk 3 and guide ring 1, and the circumference of threadingly rotating disk 3 Direction is arranged.Card lobe 2 entirety is circular arc, the draw-in groove 23 that its inner surface concave shaped is in the arc-shaped.Draw-in groove 23 outside opening is relative Bottom is wider so that draw-in groove 23 cross section is in " V " or " u "-shaped, it is also possible in isosceles trapezoid.Card lobe 2 is preferably centrosymmetric The threadingly circumferencial direction distribution of rotating disk 3.A card lobe 2 just side surface to the first pretension screw thread 31 is formed and the first pretension spiral shell Second pretension screw thread 21 of stricture of vagina 31 phase occlusion.Card lobe 2 is provided with protruding vertically away from a side surface of the first pretension screw thread 31 Guide pad 22, the width of guide pad 22 is gradually increased to end to end by root so that guide pad 22 in gathering sill 12 along footpath In time sliding, it is limited by gathering sill 12 in axial displacement.As it is shown in figure 1, guide ring 1 is towards a side surface of card lobe 2 Being provided with and card lobe 2 gathering sill 12 one to one, gathering sill 12 extends radially through inwall and the excircle of guide ring along guide ring 1 Face;Gathering sill 12 agrees with guide pad 22 phase, defines the guide pad 22 displacement along guide ring 1 circumferencial direction so that card lobe 2 Can in gathering sill radially sliding along guide ring 1 in 12.After guide ring 1 and retainer ring 4 interfix, guide ring 1 is along axle Screw thread rotating disk 3 is pressed to so that the first pretension screw thread 31 is mutually twisted with the second pretension screw thread 21 to by card lobe 2.By controlling machine Tool hand-screw twists the operating portion of worm screw 5, by turbine and worm transmission, screw thread rotating disk 3 is rotated, due to the of screw thread rotating disk 3 side One pretension screw thread 31 is engaged with the second pretension screw thread 21 phase of card lobe 2 side, has thus driven card lobe 2 along the footpath of guide ring 1 To producing displacement.In the present embodiment, card lobe 2 is along the guide ring 1 equally spaced distribution of circumferencial direction six, so, and the footpath of logical card lobe 2 To motion, it is achieved that six card lobes 2 shrink simultaneously or discharge.Certainly, it will be understood by those skilled in the art that card lobe 2 Shape be not limited to arc-shaped, its number can also have multiple conversion, as long as can be formed annular surround structure.
Further, as shown in Figures 4 and 5, the accurate chuck 6 given by the present embodiment, it is mainly used in connection tube The bump joint 7 at two ends, road.During use, the edge of bump joint 7 is put into the draw-in groove 23 of card lobe 2, and at the flange at two ends Sealing ring 8 is put between joint 7.Now there is certain interval between bump joint, do not fully seal.By manual or control The instruments such as Robot actions spanner processed screw the operating portion of worm screw 5 so that card lobe 2 moves to shrinkage direction, due to draw-in groove 23 sections Face is " V " shape (or " u "-shaped, isosceles trapezoid), and its bottom space becomes narrow gradually, and so along with the contraction of card lobe 2, two flanges connect 7 sidewalls that will be gradually gradually tightened up by draw-in groove 2 compress, and reach the effect sealed.
Accurate chuck given by the application, by arranging contractile card lobe in accurate chuck, utilizes turbine and worm Drive mechanism, realizes controlling the function of the card lobe concentric folding and unfolding of synchronization by screwing worm screw, and yoke configurations is accurate, it is possible to achieve more Accurate pretension.The operating process of accurate chuck goes out to screw outside worm screw, it is not necessary to dismount extra bolt, and pretensioning operation is simple, just In by manipulator remote control operation.And during pretension, it is only necessary to the operating portion of worm screw is screwed operation, operation stream Journey simplifies, and task difficulty is low.
Above content is to combine the further description that the application is made by specific embodiment, it is impossible to assert this Shen Being embodied as please is confined to these explanations.For the application person of an ordinary skill in the technical field, do not taking off On the premise of the present application is conceived, it is also possible to make some simple deduction or replace.
