The pull bar anchor clamps that use now, general simplex pull rod clamping device and duplex pull rod clamping device, the simplex pull rod clamping device usually needs fixed station to cooperate in clamping process, the double pull rod structure normal operation is in the symmetrical work pieces structure, and be fixed pin as auxiliary clamp, because there is certain difference in the size of workpiece, to be clamped of workpiece is the inclined plane, use conventional pull bar anchor clamps so that Workpiece clamping is inharmonious, inconvenient operation, there is shortcomings in the workpiece that processes, does not reach desirable effect.
Summary of the invention:
The technical problem to be solved in the present invention is: the operations such as a kind of convenience clamps, unclamps are provided and clamp two pull-up structure anchor clamps of coordinating.
In order to solve the above problems, the invention provides a kind of pair of pull-up structure composite fixture and comprise clip base, line shaft, the duplex pull rod pressing section, the fore-set clamping part, described line shaft is arranged in the cavity of clip base, be provided with wedge-like portion and section of rack on this line shaft, it is characterized in that: described duplex pull rod pressing section comprises short rod, long draw, connecting plate, driven shaft and jaw, the drive end of described long draw and short rod is hinged on the two ends of connecting plate, one end of described jaw is hinged on the clip base, the jaw middle part is hinged on the driven end of long draw and short rod, the other end clamping work pieces of jaw, the driven end of described driven shaft is hinged on the connecting plate middle part, drive end and described wedge-like portion are slidingly matched, and described fore-set clamping part comprises and line shaft section of rack meshed gears, with the co-axially fixed runner of gear, the fore-set of extruding workpiece lower surface and the straight pin that is arranged on the fore-set bottom are provided with the cam path that is slidingly matched with straight pin on the described runner.
Use two pull-up structure composite fixtures of technical solution of the present invention that following benefit is arranged: 1, owing to use long and short two kind pull bar, described jaw middle part is hinged on the driven end of long draw and short rod, this jaw one end is hinged on the clip base, other end clamping work pieces, this structure can be fixed clamping to the inclined plane of workpiece, 2, because anchor clamps also are provided with the fore-set clamping part, this clamping part is provided with fore-set, fore-set comes workpiece is carried out radially location by the hole on the workpiece, and 3, described line shaft is arranged in the cavity of clip base, be provided with wedge-like portion and section of rack on this line shaft, when line shaft moved in the horizontal, wedge-like portion can drive driven shaft and move up and down, the rotation of section of rack driven gear.
As preferred version, in order to reduce the loss of jaw, the position that described jaw contacts with workpiece is hinged with active chuck, often contacts workpiece, is easy to corrosion and damage, at this time only needs to change active chuck and gets final product.
As preferred version, be provided with the annular groove tangent with the cam path edge at runner, this annular groove is set; 1, eliminate fore-set in the vibrations process, loosening; 2 prevent that section of rack from can't rotate and situation that wedge-like portion is not also worked good.
