The specific embodiment

Below contrast accompanying drawing, by the description to optimum embodiment, the specific embodiment of the present utility model is described in further detail.

As shown in Figures 1 to 7, this clamping device, for the mould forging insert, the location of the workpiece such as steel plate, comprise auxiliary table 1 and arc pressuring plate 5, be provided with clamping screw 2 on auxiliary table 1, arc pressuring plate 5 is provided with pressing plate rotating shaft 6; Pressing plate rotating shaft 6 middle parts are through clamping screw 2, and arc pressuring plate 5 one ends contact with auxiliary table 1, and arc pressuring plate 5 other ends are provided with the compression flat board 8 that compresses workpiece to be positioned, compress dull and stereotyped 8 and are pressed on surface of the work; Be pressed with the locking nut 3 with clamping screw 2 adaptations on pressing plate rotating shaft 6.

Be provided with the nut shim 4 with locking nut 3 adaptations on pressing plate rotating shaft 6,

nut shim

4 and 6 welding of pressing plate rotating shaft, nut shim 4 is when guaranteeing locking nut 3 reliability of positioning; Can limit the anglec of rotation of arc pressuring plate 5 around pressing plate rotating shaft 6, further guarantee the reliability of positioning of this clamping device.Due to

nut shim

4 and 6 welding of pressing plate rotating shaft, the screw rod via hole of nut shim 4 is greater than the screw rod via hole of pressing plate rotating shaft 6 simultaneously.

Clamping screw 2 is T-shaped screw rod, and the head of T-shaped screw rod is connected with auxiliary table 1, bar section assembling pressing plate rotating shaft 6 and the locking nut 3 of T-shaped screw rod; Be provided with the T-shaped groove matched with clamping screw 2 heads on auxiliary table 1, be located at number and the visual concrete condition adjustment of distribution mode of the T-shaped groove of auxiliary table 1, the visual concrete condition adjustment of the length of the bar section of T-shaped screw rod is determined.

Compress dull and stereotyped 8 and be connected by screw 7 with arc pressuring plate 5, compressing dull and stereotyped 8 faces that contact with the Work-sheet pressing face is plane, and plane contact can guarantee that the positioning workpieces clamping area is not scratched, and guarantees workpiece surface quality.

Be provided with the adjustment cushion block between arc pressuring plate 5 one ends that contact with auxiliary table 1 and auxiliary table 1, adjust the jack that cushion block is preferably height-adjustable; When the Work-sheet pressing face surpasses the maximum height H that this clamping device can compress, adjust the height that cushion block can be raised the end that arc pressuring plate 5 contacts with auxiliary table 1, and then raising compression flat board 8 height that can locate, meet the location requirement of positioning workpieces.

Be provided with lifting screw 9 on auxiliary table 1.

Arc pressuring plate 5 one ends that contact with auxiliary table 1 are column structure, and arc pressuring plate 5 contacts with auxiliary table 1 line.

With compressing dull and stereotyped 8 arc pressuring plate be connected 5 one ends, be column structure, arc pressuring plate 5 contacts with dull and stereotyped 8 lines of compression.

As shown in Figure 8, the high state that A means that this clamping device compresses, B means the minimum state that this clamping device compresses, and the C end of arc pressuring plate 5 is cylinder, and the C end contact with auxiliary table line 1, and the D end of arc pressuring plate 5 is also cylinder, D holds and contacts with dull and stereotyped 8 lines of compression; At arc pressuring plate 5, when pressing plate rotating shaft 6 rotates, C point auxiliary table 1 relatively moves horizontally, and the D end can drive compression dull and stereotyped 8 and move horizontally.

When locking nut 3 is locked camber pressing plate 5, arc pressuring plate 5 is around rotating shaft 6 rotations, the C end of camber pressing plate 5 is preferably jack with auxiliary table 1(auxiliary table 1) contact, C holds relative auxiliary table 1 to move horizontally, the D end contacts with compression dull and stereotyped 8, drive compression dull and stereotyped 8 and move horizontally, compress dull and stereotyped 8 and contact with the Work-sheet pressing face.

Arc pressuring plate 5 is in the process of rotating, and the D end raises or reduces, and makes D end and the contour workpiece pressing of compacted workpiece.C, D two ends produce difference in height h, its maximum height difference H=L*sin θ, and the distance between the C that L is arc pressuring plate 5, D two ends, θ is the angle that camber pressing plate 5 can rotate around pressing plate rotating shaft 6; The crush pad scope is 0<h<H, but seal face is while surpassing H, and the upper cushion block of adjusting of C end pad get final product, owing to compressing end, is always and compresses dull and stereotyped 8 and contact with the processing work seal face, has avoided line to contact and weighs surface of the work wounded.

Arc pressuring plate 5 is foundry goods, and grooving on camber pressing plate 5 prevents arc pressuring plate 5 nut shim 4 and 5 interference of camber pressing plate when pressing plate rotating shaft 6 rotates.

The clamping and positioning method of this clamping device, comprise the steps:

First processing work to be positioned is placed on auxiliary table 1 and just locates, more T-shaped screw rod is pushed in the T groove of auxiliary table 1;

The pressing plate rotating shaft of arc pressuring plate 56 is passed to T-shaped screw rod, the end that camber pressing plate 5 is connected to location panel 8 is placed on the Work-sheet pressing face, camber line pressing plate 5 other ends are placed on auxiliary table 1, while as the positioning workpieces seal face, surpassing the maximum height compressed, increase between camber line pressing plate 5 and auxiliary table 1 and adjust cushion block;

Locking nut 3 is installed in T-shaped screw rod upper end;

With spanner locking locking nut 3, make it compress arc pressuring plate 5, locking nut 3 is not locked first, locked locking nut 3 after lathe checking registration, workpiece is compacted can be processed.

This clamping device, be the adjustable stroke clamp mechanism, in the process that arc pressuring plate 5 compresses, not be used in and regulate jack and make itself and workpiece contour, directly tightens locking nut 3 and get final product the fast-holding workpiece, can increase substantially the clamping efficiency of instrument; The workpiece pressing end has the flat board of compression 8 to contact with the Work-sheet pressing face, effectively solves in actual production and deposits the clamp wire contact and weigh surface of the work wounded, improves workpiece surface quality.

The above is exemplarily described the utility model; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
