Abstract
The utility model discloses a movable pressure plate which belongs to machine tool accessories. The utility model is characterized in that the operation end of a worm screw 5 is denudated on the upper part of a shell 4, one end of a pressure arm 2 and a worm wheel 3 are connected together, the other end of the pressure arm 2 extended out of the shell 4 is provided with a rotatable pressure block 1, the bottom of the shell is provided with a detachable setting plate 6, and a positioning regulation bolt 7 is penetrated through a pressing plate positioning block 8 and the setting plate 6 and assembled at the bottom of the shell 4. Accessories, such as pressure iron, a sizing block, a screw, etc. necessary for fixing a workpiece when the workpiece is processed by machine tools can be replaced by the utility model. The utility model has the advantages of convenient operation and good effects. The time needed by fixing the workpiece can be shortened.
Description
A kind of movable pressing board, the utility model belongs to machine tool accessories.
Work piece is fastened on conventional method on the workbench, is to adopt parallels to adjust working depth, and foundary weight pressure holding workpiece is by bolt locking.In the batch machining process, be to shorten the clamping time, often adopt the setting foundary weight, or with screw rod locking, or with air pressure locking, or use camlock, or with tooth bar and camlock, or the like.Their total shortcomings are that versatility is not strong.
The purpose of this utility model is a kind of worm and gear device that is installed on the platen of design, regulates depressing highly of pressure arm by the rotation of worm gear, so that workpiece is fastened on the workbench; Rely on the self-lock ability of worm-drive, in the process, workpiece then can not become flexible.
The operating side that is characterised in that worm screw 5 of the present utility model exposes the top at housing 4, one end and the worm gear 3 of pressure arm 2 link together, pressure arm 2 stretches out on the other end of housing 4 rotating briquetting 1 is housed, dismountable backing plate 6 is equipped with in the bottom of housing 4, and location adjustment screw 7 is passed the bottom that pressing plate locating piece 8 and backing plate 6 are assemblied in housing 4.
Below in conjunction with accompanying drawing the utility model is specified:
Fig. 1: the structural representation of movable pressing board;
Fig. 2: A-A profile;
Fig. 3: B-B profile.
Worm gear 3, worm screw 5 are installed in the housing 4 by bearing, the operating side of worm screw 5 exposes the top at housing 4, one end and the worm gear 3 of pressure arm 2 link together, pressure arm 2 stretches out on the other end of housing 4 rotating briquetting 1 is housed, dismountable backing plate 6 is equipped with in the bottom of housing 4, and location adjustment screw 7 is passed the bottom that pressing plate locating piece 8 and backing plate 6 are assemblied in housing 4.
In the use, according to the size of machining tool workbench T type groove, select the pressing plate locating piece 8 of corresponding size for use earlier, and the exposed length of adjustment screw 7, locating piece 8 can be pushed in the T type groove more conveniently, make the gap of movable pressing board and work top as far as possible little again.Rotary worm 5, worm gear 3 servo-actuateds, the pressure arm 2 that is connected on the worm gear moves down, and the briquetting 1 by pressure arm 2 the other end just is fastened on workpiece on the workbench.Counter-rotating worm screw 5, pressure arm 2 rises, and briquetting 1 unclamps, and workpiece can take out easily.
In the bottom of movable pressing board, dismountable backing plate 6 is housed, improve effective working depth of movable pressing board with this; Or, change effective working depth of movable pressing board by changing the thickness of backing plate 6.
When the utility model can replace the lathe processing work, be annexes such as the essential foundary weight of fixation workpiece, parallels, screw rod; Within effective working depth of movable pressing board, the pressure holding height can steplessly change; And can change effective working depth of movable pressing board neatly; Easy to operate, fastening effective, widely applicable, can shorten the required time of fixation workpiece.
