Detailed description of the invention
With reference to Figure of description 1 to accompanying drawing 6, the present invention is described in detail below.
A kind of flexible fixture for casing, including base 1, clamp body 2, Anchor plate kit 3, servo clamping device 4, gear wheel 5 with planar rectangular screw thread, little gear 6, it is characterized in that, there is installing hole at the two ends of described base 1, described clamp body 2 is threaded connection and is fixed in the middle part of base 1, described Anchor plate kit 3 is threaded connection the upper surface being arranged on clamp body 2, described servo clamping device 4 is arranged on the upper surface of clamp body 2, the gear wheel 5 of described band planar rectangular screw thread is arranged in the middle of base 1 and clamp body 2, with servo clamping device 4 by planar rectangular threaded engagement, carry out gear with little gear 6 to coordinate, described little gear 6 has three, it is distributed on the gear wheel 5 of band planar rectangular screw thread around, carry out gear cooperation.
Further, described clamp body 2 includes that chute 21, connecting hole 22, described chute 21 have three, being distributed on clamp body 2, be used for carrying servo clamping device 4, servo clamping device 4 can being made to move above, described connecting hole 22 has three, it is distributed on clamp body 2, is connected with Anchor plate kit 3.
Further, described Anchor plate kit 3 includes pressing plate 31, pin-and-hole 32, alignment pin 33, bolt hole 34, fixing bolt 35, described pressing plate 31 is to 7 pressuring actions of workpiece, described pin-and-hole 32 is in pressing plate 31 termination, described alignment pin 33 fixes workpiece 7 by after pin-and-hole 32, described bolt hole 34 has three, makes Anchor plate kit 3 adjustable, and described fixing bolt 35 is connected with clamp body 2, for fixation clip 31 by bolt hole 34.
