A spring slice and a positioning screw is also added on the work table, making the whole device become automatic production. The utility model has the advantages of high precision, high work efficiency, compact structure, flexible operation, convenient operation and multifunction and formulates a key in 30 seconds.

Description

All-automatic multi-function key milling machine

The utility model belongs to the table device of grinding metal parts.

Employed in the market repair key milling-tapping machine mostly is armstrong's patent, its structure is by shaking handwheel, the milling cutter that is driven, workbench, compositions such as profiling bar, workbench is fixed on the fixed axis by sliding sleeve, fix a profiling bar in milling cutter one side, make workbench on fixed axis, make horizontal move left and right with shaking handwheel, taking original key in a side is that standard is the location with the profiling bar, on workbench, just be replicated a new key the same through manual operations with the left side original key near the milling cutter position, the shortcoming of this machine is manual operations, labour intensity is big, inefficiency, not steady by workbench hand-manipulated, the preparation key is of poor quality, imitated precision is low.

The utility model provides a kind of novel key milling-tapping machine, makes machine reach full-automatic, multi-functional purpose thereby increased motor, decelerator and eccentric wheel on original old-fashioned machine.

Structure of the present utility model is to have increased new parts again on former machine includes the basis of handwheel, milling cutter, imitative type bar and workbench, be made up of motor, decelerator, eccentric wheel and eccentric wheel pull bar and manual or automatic public sliding shaft sleeve, this motor is that 1380 ac motors that change, worm type of reduction gearing, the worm gear transmission ratio that decelerator is two-stage gear no-load voltage ratio are respectively 48:1 for 220 volts, 120 watts of interchanges, rotating speed; 24:1, fixing eccentric wheel before the screw rod, to be driven eccentric speed be 1.58 rev/mins, the sliding axle that eccentric wheel circles can prepare a key, fixing workbench is with two kinds of duties, the one, under automatic condition, drag work by motor, another kind is to work under the manual case, automatically the time, drive and remove handwheel and hand wheel pole workpiece, workbench by hold-down screw be fixed on the screw, eccentric wheel rotation, the eccentric links that is driven by eccentric wheel drives workbench by little sliding axle and screw and does back and forth and move horizontally; Stationary table puts outside sliding axle, it is fastening with screw that little sliding axle right-hand member is being fixed handwheel, inner axle claims the screw thread between the little sliding axle, make workbench make move left and right with little sliding axle rotation, drive in the time of manually and remove little sliding axle and top pin, can adorn imperial handwheel and hand wheel pole with the sliding shaft sleeve right-hand member drives workbench by screw mandrel and screw equally and moves horizontally, workbench is provided with key root locator, locator is made up of with manual pressing plate locating rack and two location retainings, spacing on two location retainings and the locating rack is adjustable, concrete grammar is to be the horizontal strip hole with bolting hole between positioning of one of them and the locating rack, at the key root device right-hand member of fullying recover from an illness surely manual depression bar is arranged, key root locator is rotated up and down around axle, after new and old key is good by pressure board, the hand depression bar, two location keep off being in harmony and block new and old two key roots on the locator, to determine the relative position of key, as calibration, this locator is below two key pressing plates, unclamp depression bar after the new and old key positioner, set back automatically by spring action.After changing milling cutter, can adjust spacing easily like this, save rapidoprint simultaneously and improved precision again.Be provided with dog screw on the workbench again; prevented that workbench from directly not contacting under the working condition with milling cutter with imitative type backstay; shield mutually; in the workbench outside spring leaf is installed; because the inside elastic force of spring leaf; make workbench in working order down automatically near milling cutter and imitative type backstay; under off working state, leave milling cutter and imitative type backstay again automatically; increased the automaticity of this machine; axle head has been installed drill point on the milling cutter right side; when making key, can make pellet shot from a slingshot again; make spring and boring; increased the function of this machine; the complete machine component locations is to have the right back of the bearing bracket stand of milling cutter at board; big belt wheel is being adorned in the termination; motor is equipped with at the board rear portion; and it is moving between the big belt wheel with the belt holder; heavy with motor shaft in the board left side is decelerator directly; on the decelerator right side is the active operation table top; workbench can all around move on board; when mobile backward; treat that bitting has been in harmony the aligning milling cutter, wherein imitative type positioning seat and key root locator are all at the workbench rear portion, and whole device all is fixed on the board.

Its course of work is as follows: existing key and new key to be prepared are placed on respectively under the pressing plate of workbench, fixedly card well, press key positioner device depression bar then, check two relative positions that key is put with the location of two on locator retaining, after distance presses between the adjustment, push away workbench (manually time) forward and lean on the elastic force of the spring leaf below the workbench when locating, make milling cutter work, workbench from left to right, by old on the key breach and imitative type backstay all the time near, milling nine and move from left to right, is standard with the left side key, and the new key of aiming at milling cutter is promptly milled out and the same key of old the same tooth pitch with size.

Advantage of the present utility model: imitated precision height, new and old key error be less than 0.06mm, and it is convenient that high efficiency can be prepared a key, multi-functional, compact conformation, use flexible operating in 30 seconds.
