The specific embodiment
Contrast accompanying drawing below, the description by to optimum embodiment is described in further detail the specific embodiment of the present invention.
To shown in Figure 7, this clamping device is used for the location of workpiece such as the mould forging is inserted, steel plate, comprises auxiliary table 1 and arc pressuring plate 5, is provided with clamping screw 2 at auxiliary table 1 as Fig. 1, and arc pressuring plate 5 is provided with pressing plate rotating shaft 6; Clamping screw 2 is passed at pressing plate rotating shaft 6 middle parts, and arc pressuring plate 5 one ends contact with auxiliary table 1, and arc pressuring plate 5 other ends are provided with that to compress compressing of workpiece to be positioned dull and stereotyped 8, compress dull and stereotyped 8 and are pressed on surface of the work; Be pressed with the locking nut 3 adaptive with clamping screw 2 at pressing plate rotating shaft 6.
Be provided with the nut shim 4 adaptive with locking nut 3 at 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 arc pressuring plate 5 around the anglec of rotation of pressing plate rotating shaft 6, further guarantee the reliability of positioning of this clamping device.Because nut shim 4 welds with pressing plate rotating shaft 6, 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 type screw rod, and the head of T type screw rod is connected with auxiliary table 1, bar portion assembling pressing plate rotating shaft 6 and the locking nut 3 of T type screw rod; Be provided with the T type groove that matches with clamping screw 2 heads at auxiliary table 1, be located at number and the visual concrete condition adjustment of distribution mode of the T type groove of auxiliary table 1, the visual concrete condition adjustment of the length of the bar portion of T type 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 the plane, and plane contact can guarantee to locate the workpiece clamping area and not be scratched, the assurance workpiece surface quality.
Between arc pressuring plate 5 one ends that contact with auxiliary table 1 and auxiliary table 1, be provided with the adjustment cushion block, 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 contact with auxiliary table 1, and then improve and compress dull and stereotyped 8 height that can locate, satisfied location requirement of locating workpiece.
Be provided with lifting screw 9 at 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.
Be column structure with compressing dull and stereotyped 8 arc pressuring plates that are connected, 5 one ends, arc pressuring plate 5 with compress dull and stereotyped 8 lines and contact.
As shown in Figure 8, the high state that A represents that this clamping device compresses, B represents 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 it also is cylinder that the D of arc pressuring plate 5 holds, D holds and compresses dull and stereotyped 8 lines and contact; During around pressing plate rotating shaft 6 rotation, C point auxiliary table 1 relatively moves horizontally at arc pressuring plate 5, and D holds to drive and compresses flat board 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, D end with compress flat board 8 and contact, drive compresses dull and stereotyped 8 and moves horizontally, and compresses dull and stereotyped 8 and contacts with the Work-sheet pressing face.
Arc pressuring plate 5 is foundry goods, and grooving on the 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 comprises the steps:
Earlier processing work to be positioned is placed on the auxiliary table 1 and just locatees, again T type screw rod is pushed in the T type groove of auxiliary table 1;
The pressing plate rotating shaft 6 of arc pressuring plate 5 is passed T type screw rod, an end that camber pressing plate 5 is connected location dull and stereotyped 8 is placed on the Work-sheet pressing face, camber line pressing plate 5 other ends are placed on the auxiliary table 1, as locate the Work-sheet pressing face when surpassing the maximum height compress, between camber line pressing plate 5 and auxiliary table 1, increase the adjustment cushion block;
In T type screw rod upper end locking nut 3 is installed;
With spanner locking locking nut 3, make it compress arc pressuring plate 5, locking nut 3 is not locked first, treats the accurately locked locking nut 3 in back of lathe checking location, and workpiece is compacted can be processed.
This clamping device is the adjustable stroke clamp mechanism, in the process that arc pressuring plate 5 compresses, not be used in and regulates jack and make itself and workpiece contour, directly tightens locking nut 3 and gets final product quick workpiece pressing, can increase substantially the clamping efficient of instrument; The workpiece pressing end compresses dull and stereotyped 8 and contact with the Work-sheet pressing face, effectively solves to deposit clamp wire in the actual production and contact and weigh wounded surface of the work, the raising workpiece surface quality.
Above the present invention has been carried out exemplary description; obviously specific implementation of the present invention is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; or without improving design of the present invention and technical scheme are directly applied to other occasion, all within protection scope of the present invention.
