The utility model has the structure that a bottom board of a working table is fixedly provided with a guiding socket sleeve; the internal of the guiding socket sleeve is fixedly provided with a guiding upper sleeve and a guiding lower sleeve; both ends of a guiding pin arranged on a turning guiding axle are arranged between the guiding upper sleeve and the guiding lower sleeve; the upper end of the turning guiding axle is provided with a turning mold and a clamper; the lower end is provided with a spring; the upper part of the clamper is provided with a clamping oil cylinder; thus, the utility model has the characteristics that the structure is simple, the drilling machine is capable of automatically clamping and turning, the work efficiency is high, the machining precision is high, etc.
Description
The utility model relates to a kind of metalworking machinery, especially to processing the structural improvement of universal joint special drill press.
At present, the boring of machining for example drills through oilhole or store oil lumen pore on the Hooke's joint, adopt bench drill to carry out manual operations more.Thereby four spindle noses in the workpiece will just can be finished the processing of boring through No. four clampings.Therefore, exist labour intensity big, work efficiency is low, the bigger deficiency that waits of the error of boring.
The purpose of this utility model is at the deficiencies in the prior art, provides a kind of rational in infrastructure, can clamp and transposition work efficiency height, the numerical control drilling machine that machining accuracy is higher automatically.
Major scheme of the present utility model is: be fixed with the guiding cover for seat on described workbench base plate, be fixed with in it that guiding goes up cover and guiding is trapped, and the two ends of being located at the guide finger on the revolution axis of guide are in guiding and go up between cover and guiding trap; Upper end at the revolution axis of guide is provided with mold rotation and anchor clamps, and the lower end is provided with spring, and is provided with the clamping cylinder that is subjected to the control of numerical control case above described anchor clamps.
Described guiding cover for seat is to be fixed on the workbench base plate through rotary table, and is provided with several alignment pins on described rotary table, and mold rotation is provided with corresponding set pin sleeve.The lower end of described guiding cover for seat is provided with adjusting screw(rod); Described rotary table is provided with the alignment pin of four tapers that are perpendicular to one another.
On the workbench base plate, be provided with and fix, and screw mandrel driven by stepper motors, on described screw mandrel, be provided with movement nut and be located at therebetween screw mandrel live body, and the latter is connected with drilling head base on placing rail plate by the screw mandrel bearing.
Therefore, the utlity model has rational in infrastructurely, easy to operate, equipment manufacturing cost is lower, the work efficiency height, and the location of boring, the precision of the degree of depth are higher, can alleviate characteristics such as working strength of workers greatly, are a kind of special-purpose rigs that liked by manufacturing enterprise.
Fig. 1 is a kind of agent structure schematic diagram of the present utility model.
Fig. 2 is the local enlarged diagram of Fig. 1.
Fig. 3 is a kind of structural representation that guiding goes up cover in the utility model.
Below by embodiment, the utility model is further described in detail.By variable-ratio belt pulley 5 power is delivered to drilling head main shaft 9 by motor 2, and is delivered on the drill bit, realize boring the active force transmission of processing.Feeding power is realized by screw mandrel 17 by stepper motor 12, screw mandrel 17 is installed on the worktable panel 16 by holder 13, screw mandrel rotates under the driving of stepper motor, drive two movement nut 14 and do axially-movable, and power is delivered on the rail plate 11 by screw mandrel live body 15 therebetween, make the drilling head base 10 and the whole drilling head that are installed on the rail plate 11 carry out axial feed, be drilled into set depth after, withdraw from automatically.Then, being pressed on clamping cylinder 29 on the workpiece 27 is subjected to 30 controls of numerical control case and discharges, the revolution axis of guide 20 moves upward under the effect of spring 19, make 45 ° of the rotations under cover 23 on the guiding and guiding are trapped 21 effect of the guide finger 22 of lateral pin on it, mold rotation through being fixed on its end face 25 thus drives also rotation together of anchor clamps 26 (referring to accompanying drawing 1 to accompanying drawing 3).
Then, be fixed on the clamping cylinder 29 of anchor clamps top, be subjected to the control of numerical control case and press workpiece 27 and anchor clamps 26 downwards, make the revolution axis of guide 20 compression springs that fix with it, move downward, be located at the guide finger 22 of revolution on the axis of guide 20 guiding trap 21 and guiding under the effect of cover 23, in like manner make anchor clamps 26 rotate 45 ° again, at this moment, being located at four alignment pins 24 of guiding on the cover for seat 8 inserts in the corresponding set pin sleeve on side's mold rotation 25 provided thereon simultaneously, thereby realized anchor clamps 26 half-twists automatically, and more accurately located.Wherein, described guiding cover for seat 8 is to be fixed on the workbench base plate 16 through rotary table 7.After treating that workpiece 27 clamped oil cylinders 29 clamp fully, numerical control case 30 is control step motor 12 work, and by the drilling depth that sets, thereby the feeding that repeats above-mentioned drilling head base 10 has realized the purpose of automatic drilling.
Usually, on a workbench base plate, quadruplet numerical control drilling machine independently toward each other can be set simultaneously, and concentrate and be subjected to a control cabinet control, operation.
