The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
In conjunction with Fig. 1 and Fig. 2, the portable pressing plate of the present invention comprises clamping part 1, Z-shaped part 2, force part 3 and fulcrum part 4 from left to right successively.The front end cross section of clamping part 1 is circular arc, referring to Fig. 2.The lower end of clamping part 1 is provided with step, comprises step upper surface 11 and step side 12, and step side 12 is arc surface.3 places, force part are provided with slotted hole 31, by Z-shaped part 2, are connected with clamping part 1.Fulcrum part 4 is provided with straight trough 41 below.
As shown in Figure 3, clamping device of the present invention is that above-mentioned pressing plate 6 is combined with clamp body 14, by the clamping part 1 of pressing plate and one end clamping work pieces 5 of clamp body 14.Slotted hole 31 places in pressing plate force part 3 penetrate screw rod 9, and the two ends of screw rod 9 are fastening with the force part 3 of clamp body 14 and pressing plate by locking nut 11 and nut 8 respectively.Nut 8 is provided with packing ring 7 with the junction of screw rod 9, in the middle of screw rod 9, is provided with spring 10, and the two ends of spring 10 contact with force part 3 and locking nut 11 respectively.Clamp body 14 other ends are by the fastening pillar 12 of locking nut 13, and the upper end of pillar 12 is located in pressing plate straight trough 41, by pillar, realize the supporting role to pressing plate fulcrum part 4.
Pressing plate of the present invention is the diameter dimension size according to the endoporus of required processing thin-walled sleeve workpiece and cylindrical, first the front end circular arc of portable pressing plate clamping part 1 and the radius size of lower end step side circular arc are processed in design, and two radial distance sizes between circular arc, step upper surface 11 is contacted to greatest extent with the thin-walled of sleeve workpiece.Then the screw rod 9 of required installation is, the height dimension of the axial length dimension design processing Z-shaped part 2 of the height dimension of clamp nut 11 and workpiece 5 just in time can be stuck between clamp body 14 and pressing plate clamping part 1 workpiece 5.Finally according to the needs design processing slotted hole of force part 3 of work-handling and the size of the straight trough of fulcrum part 4.When pressing plate 6 is combined with clamp body 14, by screw rod 9 lower ends, through after pressing plate 6 middle part slotted holes 31, pocketed springs 10 and locking nut 11, adopt and be threaded with clamp body 14, after screw rod 9 upper end suit packing rings 7, adopts and be threaded with nut 8.Pillar 12 lower end suit locking nuts 13, adopt and are threaded with clamp body 14, and pillar 12 upper ends are arranged in the straight trough 41 of pressing plate 6.Until workpiece 5, complete behind location, unscrew locking nut 11,13, adjusting screw(rod) 9 and pillar 12, after suitable height, screw locking nut 11,13, and pressing plate 6 is moved to correct position along straight trough 41 and slotted hole 31.Fastening nut 8, moves down packing ring 7 and pressing plate 6, relies on the step of the clamping part 1 of pressing plate 6 to realize the clamping to workpiece 5.When thin walled cylinder body workpiece 5 completes after processing, unscrew nut 8, rely on the elastic force promotion pressing plate 6 of spring 10 to move up, make workpiece 5 released, promote pressing plate 6 and move after straight trough 41 and slotted hole 31, can realize freely loading and unloading of workpiece 5.And when larger change occurs the axial length dimension of workpiece 5, only need to change screw rod 9 and the pillar 12 of different length size.
