This drawbench is generally two pawls or three-jaw drawbench, be applicable to the outward flange of drawing small parts, cannot be by outward flange drawing, can only be by withdrawing pattern hole or the drawing of stress hole time when relatively large workpiece, on drawbench, the quantity of pulling claw is corresponding with the drawing hole on workpiece. Like this, the drawbench of fixed qty pulling claw uses limited, and machine repairing department need to be equipped with multiple drawbench, at least needs to be equipped with two pawls, three-jaw, five pawls, four kinds of chest expanders of seven pawls, expense is high, storage, use inconvenient. As use unmatched drawbench to dismantle mechanical part, unbalance stress, fragile drawbench and mechanical part.
Summary of the invention
The object of the invention is to solve above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, easy to use, applied widely, the adjustable drawbench that operating efficiency is high.
The present invention solves the problems of the technologies described above adopted technical scheme:
A kind of adjustable drawbench, be provided with drawing cover, it is characterized in that drawing cover bottom is provided with lower locating flange, the drawing of lower locating flange top puts and is provided with the upper locating flange that can slide up and down along drawing cover, upper locating flange is provided with relative annular slot with lower locating flange, between upper locating flange and lower locating flange, be provided with at least three contiguous blocks, contiguous block is provided with pulling claw connecting hole, the upper and lower both sides of contiguous block are provided with and upper locating flange, the arc clamping block that annular slot on lower locating flange matches, clamping block is embedded in annular slot, upper locating flange with on lower locating flange, be evenly equipped with the relative hole that is fastenedly connected, be fastenedly connected and in hole, be provided with connecting bolt.
Annular slot described in the present invention is to be provided with annular breach with drawing cover contact position on upper locating flange and lower locating flange, and annular breach and drawing cover outside surround annular slot.
The arc clamping block of the upper and lower both sides of contiguous block described in the present invention is: the arc clamping block fitting with drawing cover that contiguous block inner side is provided with outstanding contiguous block up and down.
Outside, drawing cover bottom described in the present invention is provided with along the deck of drawing cover radial protrusion, and lower locating flange is set in drawing and puts and be stuck on deck
When use, loosening connecting bolt, regulate contiguous block in annular slot week position upwards, withdrawing pattern hole on itself and workpiece to be removed is matched, then be fastenedly connected bolt and make locating flange compress and be fixedly connected with piece with lower locating flange, by with workpiece to be removed on the match pulling claw of number of withdrawing pattern hole be connected on contiguous block through pulling claw connecting hole. Again by drawing cover with leading screw through being threaded, the drag hook of pulling claw is hooked on the withdrawing pattern hole, stress hole of dismounting parts, drives leading screw to move forwards or backwards, leading screw pushes or pulls drawing cover, drives pulling claw that parts are pulled out from machinery. By the adjusting of contiguous block number and position, can recall and be applicable to the drawbench that various plant equipment are used, make it have two functions to the multiple drawbench of seven pulling claws, the scope of application is wide. Only drawbench can complete the function of multiple drawbench, have simple in structure, easy to use, applied widely, the advantage that operating efficiency is high. By the adjusting of contiguous block number and position, recall the drawbench matching with plant equipment, not fragile drawbench and mechanical part.
The present invention's easy processing simple in structure, draws horse device applicable to all kinds. Draw contiguous block number and position by improvement, can expand the scope of application of drawing cover. The design of contiguous block inner surface circular arc type, increases tension, anti-shearing force. Be particularly suitable for the manual drawbench that pulling capacity is larger.
