Abstract
The utility model provides a quick assembly disassembly closing device, by the clamp plate, taut bolt and nut, push up tight screw rod and constitute, the two opposite sides of the screw of clamp plate afterbody have symmetrical dead slots, groove width B equals D-2 p, the tank bottom is the arc, the diameter D of its place circle equals D +1, push up tight screw rod both sides mill flat, mill the width B between the planomum equal D-2 p-0.3, wherein D is the outer diameter of pushing up tight screw rod, p is thread pitch. The utility model is used for processing equipment such as wire cut electrical discharge machining bed, milling machine adds the clamp of man-hour to the work piece tightly, can realize fast loading and unloading according to the nimble adjustment of work piece altitude variation, does not need the cushion, labour saving and time saving, convenient to use.
Description
Technical field
The utility model relates to a kind of machining hold down gag, particularly without cushion block, and adjustable for height quick loading and unloading hold down gag.
Background technology
Processing work on wire cutting machine tool, milling machine at first will be with Work-sheet pressing.Existing hold down gag is made up of pressing plate, turnbuckle and nut, cushion block, because workpiece is wide in variety, height dimension changes greatly, just need adjust with some different cushion blocks, and cushion block is changed trouble, wastes time and energy, and uses very inconvenient.Also useful fastening screw replaces cushion block, but height change is when big, and the turn screw speed is slow, and is equally very inconvenient.
The utility model content
The technical problems to be solved in the utility model provides a kind of without cushion block, adjustable height, quick loading and unloading hold down gag time saving and energy saving, easy to use.
The technical solution of the utility model is: load and unload hold down gag fast, constitute by pressing plate, turnbuckle and nut, fastening screw, improvements are dead slots that screw two opposite side of pressing plate afterbody have symmetry, the wide B=d-2p of dead slot, and the dead slot bottom is an arc, arc place diameter of a circle D=d+1, two pairs of side millings of described fastening screw are flat, and two mill the width b=d-2p-0.3 between flat horizontal surface, and wherein d is the fastening screw external diameter, p is a thread pitch, and each parameter unit is mm.
During with this device workpiece pressing, as long as the dead slot that flat horizontal surface is aimed at the pressing plate screw that mills with fastening screw, pressing plate just can move up and down, adjust to the height that needs rapidly, then with the fastening screw half-twist, threaded portion on the screw rod is connected with threaded portion in the pressing plate screw, screws the nut of turnbuckle again, just workpiece can be clamped.Operate in reverse order when unclamping workpiece, so this device can realize quick loading and unloading, use very convenient.The size that strict control screw rod mills flat size and pressing plate screw dead slot can guarantee that then this device compresses reliably, and adjust nimbly and freely.

Fig. 2 is the pressure plate structure schematic diagram;
Fig. 3 is the fastening screw schematic diagram;
Fig. 4 is along A-A place cutaway view among Fig. 3.
The specific embodiment
As figure, when this device was clamped condition, fastening screw 4 was threaded by part with pressing plate 2 afterbody screws, and the head of turnbuckle 5 is contained in the T type groove of workbench, and 3 heads with pressing plate 2 of nut are pressed on the workpiece 1.When unclamping,, and screw rod 4 half-twists are got final product as long as unscrew nut 3.Pressing plate afterbody screw two opposite side are processed into dead slot, the wide B=d-2p of dead slot, dead slot bottom arc place circular diameter D=d+1, two pairs of side millings of fastening screw are flat, and two mill the width b=d-2p-0.3 between flat horizontal surface, and wherein d is the fastening screw external diameter, p is a thread pitch, and each parameter unit is mm.
Claims (1)
1, a kind of quick loading and unloading hold down gag, constitute by pressing plate, turnbuckle and nut, fastening screw, it is characterized in that screw two opposite side of pressing plate afterbody have the dead slot of symmetry, the wide B=d-2p of dead slot, the dead slot bottom is an arc, arc place diameter of a circle D=d+1, two pairs of side millings of described fastening screw are flat, and two mill the width b=d-2p-0.3 between flat horizontal surface, and wherein d is the fastening screw external diameter, p is a thread pitch, and each parameter unit is mm.
