Utility model content
The utility model provides a kind of self can clamp the spiral-plate heat exchanger skull drilling equipment of plurality of specifications skull with clamping structure.
This programme is as follows: spiral-plate heat exchanger skull drilling equipment, comprise pedestal and the workpiece support platform being positioned at pedestal side direction, pedestal is provided with can the distribution of vertical motion and the ejector pin that can move horizontally, the end face of distribution and ejector pin is inclined-plane, two inclined-planes offset, pedestal is stretched out in the end of ejector pin, the jacking block that can rotate along selve support axle is provided with between pedestal and workpiece support platform, the side that jacking block is positioned at ejector pin is plane, the side of jacking block ejector pin is dorsad round and smooth convex surface, the end of ejector pin can hold out against the lower end plane of jacking block, the boss that can block convex surface restriction jacking block rotational angle is provided with in the side of brace table, convex surface and the Plane intersects place of jacking block upper end form the top of positioning workpieces, this is top can offset with the side of pedestal, promote and stretch out pedestal and fix with one end of a plate, stage clip is provided with between connecting plate and pedestal, the middle part sliding sleeve of connecting plate is provided with vertical drive rod, the top of drive rod is connected with the piston rod of cylinder, drive rod be circumferentially with tapered flanges, tapered flanges can withstand connecting plate forces connecting plate to move downward, the other end of connecting plate is provided with drill bit, upper in the laterally disposed locating piece with strip-shaped clamp groove of drive rod at pedestal.
This programme operation principle is as follows: when processing the skull of spiral-plate heat exchanger, first skull is placed on brace table, a side of skull is inserted in the strip-shaped clamp groove of locating piece, then the piston rod of cylinder moves downward, drive drive rod is downward, when the tapered flanges of drive rod props up connecting plate, connecting plate is forced to move downward, the drill bit of connecting plate side is downward, drive is promoted downwards by connecting plate opposite side simultaneously, the inclined-plane promoting lower end forces ejector pin to move to jacking block direction, withstand jacking block lower end, the top lower surface withstanding skull of jacking block upper end, make top cover clamping position more firm, until bit run can be holed to skull after putting in place.After having holed, first the side of skull is extracted out from locating piece, then in the process of jacking block return, top by jack-up skull, skull is tilted, is convenient to inloading part.
The utility model drilling equipment carries clamping structure, and when needing the skull of clamping position different specification size, only need to change the locating piece with different size strip-shaped clamp groove, easy to use, cost is low.
Further, on promoting, be axially arranged with bar shaped guide groove along what promote, pedestal is provided with pilot pin, and the end of pilot pin is positioned at bar shaped guide groove.During sales promotion campaign, pilot pin has guide effect to distribution.
Further, in order to realize automatically reseting of jacking block, the lower end of jacking block and one end of extension spring are fixed, and in the horizontal direction, the other end of extension spring is fixed on pedestal in extension spring.
Further, in order to realize automatically reseting of ejector pin, be provided with the stage clip resetted for ejector pin in the periphery of ejector pin.
