Description
Technical field
This utility model relates to machinery fixture technology field, particularly relates to a kind of accurate self-centering chuck being applicable to clamp super-huge annular element.
Background technology
Work holder is for clamping the device of workpiece on lathe, mainly utilizes the movable jaw being distributed on chuck seat to move radially Workpiece clamping and location.Such as the scroll chuck schematic diagram that accompanying drawing 1 is prior art, including chuck body 10a, claw the 20, first bevel gear 30 and the second bevel gear 40, being provided with the through hole 101 for placing workpiece in the middle of described chuck body 10a, claw 20 is three and is uniformly arranged on the claw track 50 on the end face of chuck body 10a in 120 ° of angles；Described second bevel gear 40 and the first bevel gear 30 engages and the back side of the second bevel gear 40 is provided with helicla flute 60；Described first bevel gear 30 is provided with, away from one end of chuck body 10a axis, the square hole 70 inserted for spanner；Described claw 20 is provided with multiple latch 80 for being meshed with helicla flute；When scroll chuck works, the square hole 70 spanner being inserted the first bevel gear 30 rotates the first bevel gear 30, drive the rotation of the second bevel gear 40 again, the helicla flute 60 at second bevel gear 40 back side rotates and drives three claws 20 to do radial motion along the claw track 50 of chuck body 10a again, thus clamps or unclamp workpiece.But this structure is only applicable to diameter workpiece within hundreds of millimeter, when the radial dimension of annular workpieces is bigger, even more than during chuck external diameter, claw is just difficult to directly clamp annular workpieces, this fixture scope of application is little, has limitation, and needs to rotate with wrench dynamic bevel gear, wasting time and energy, work efficiency is relatively low.
Chinese utility model patent 201520148999.4 discloses a kind of clipping chuck of split being suitable for annular workpieces, including chuck, the external diameter of chuck is less than the external diameter of annular workpieces, chuck surface radially cross distribution is provided with four groups of guide chutes, often slide on group guide chute and be provided with tabular fixture, tabular fixture bottom surface arranges the slide block coordinated with guide chute in the inner part, when tabular fixture slides into outermost, outer end can extend to the outside of chuck, tabular fixture upper surface is provided with internal stop and outer baffle block, annular workpieces is embedded between internal stop and outer baffle block, it is respectively equipped with ball screw on internal stop and outer baffle block and holds out against inner headed face and the periphery of annular workpieces, ball screw holds out against the end face of annular workpieces and uses corrugated surface.Solve the problem that tradition chuck is difficult to the excessive even more than annular workpieces of chuck external diameter of stable holding radial dimension.
Although this application solves, radially larger-size annular workpieces is clamped, the problem that its stability is difficult to ensure that, but still come with some shortcomings: this application uses four positions of four split type tabular fixtures cross distribution of de-clamping annular workpieces respectively, by the internal stop on tabular fixture and outer baffle block and combine the ball screw being respectively equipped with on it and hold out against inner headed face and the periphery of annular workpieces, thus realize gripping of annular workpieces, during Gai, holding out against of ball screw needs manual operation, and manual operation makes four tabular fixtures cannot hold out against annular workpieces simultaneously, and annular workpieces also cannot ensure unanimously at this pressure being subject to everywhere, annular workpieces is caused to clamp not strongly, sideslip it is susceptible to during Vehicle Processing, hit cutter situation；In addition, the ball screw arranged on internal stop and outer baffle block respectively and is point cantact mode between the inner headed face of annular workpieces and periphery, contact area is little between the two, when there is little flaw or pit on the inner headed face and periphery of annular workpieces, is difficulty with the accurate clamping of annular workpieces.
Chinese invention patent 201410725732.7 discloses a kind of scroll chuck, and described base is evenly equipped with three flutings, and fluting medial surface is equipped with the first screw, is mounted on clamping device in this first screw；Described clamping device includes that screw rod, screw rod are provided with on moveable Mobile base and Mobile base the claw connected, and screw rod one end extends outside the base and is connected with motor, and this utility model solves traditional chuck needs clamping manually, the problem wasted time and energy.Although this utility model drives corresponding screw rod to drive claw to move forward and backward by motor, realize automated exchanged cutter, but still suffer from some problems: in work process, the output torque of three motors is difficult to keep uniform synchronization, and during for clamping super-huge workpiece, frictional force between its worm-and-nut strengthens, loss is big, thus the distance causing electric motor driven screw to drive corresponding claw to move changes, workpiece cannot be clamped by claw simultaneously, self-centering cannot be realized, positioning clamping precision is low, it is difficult to meet high-accuracy processing request.
To sum up, modern mechanical digital control processing field is increasingly intended for the production of large-scale customization and lot-size, and traditional frock clamp can not meet current Production requirement.
