Detailed description of the invention
With reference to Figure of description 1 to accompanying drawing 5, the fixture of a kind of fixing E-type bolt of the present utility model is described in detail below.
The fixture of a kind of fixing E-type bolt of the present utility model, its structure comprises train wheel bridge 1, lower plate 2, guiding returning device 3 and hold down gag 4, described train wheel bridge 1 is arranged on the top of lower plate 2, lead returning device 3 and hold down gag 4 is provided with between described train wheel bridge 1 and lower plate 2, described guiding returning device 3 comprises two, be symmetricly set on the two ends, left and right of train wheel bridge 1 and lower plate 2, described hold down gag 4 is arranged on the middle part of train wheel bridge 1 and lower plate 2, described hold down gag 4 comprises compression stud 41 and clamp nut 42, described compression stud 41 lower end and lower plate 2 fix, upper end is through train wheel bridge 1, and it is fastening by clamp nut 42, described train wheel bridge 1 is respectively arranged with the symmetrical inner side of lower plate 2 the clamping contact surface 5 contacted with E-type bolt, described clamping contact surface 5 matches with the outer surface of E-type bolt, E-type bolt levelness and add clamping in man-hour firmly when ensureing clamping, ensure that crudy, described lower plate 2 is connected with workbench by jockey 6.
Described jockey 6 comprises four lower plate fastening bolts 61, and four described lower plate fastening bolts 61 points two groups, are symmetricly set on the two ends, left and right of lower plate 2.Can conveniently assemble and disassemble lower plate 2, to change the frock of different model, adapt to the E-type bolt processing of different model.
Described guiding returning device 3 comprises guide pillar 31 and spring 32, the lower end of described guide pillar 31 is fixedly connected with lower plate 2, upper end is through train wheel bridge 1, train wheel bridge 1 is provided with through hole, guide pillar 31 is each passed through through hole, and coordinate with via clearance, the guide pillar 31 between described train wheel bridge 1 and lower plate 2 is provided with spring 32.Guide pillar 31 pairs of train wheel bridges 1 move down and play guide effect, and are provided with spring 32 between train wheel bridge 1 and lower plate 2, when getting workpiece, can make train wheel bridge 1 return, are convenient to take out workpiece.
