In order to solve above technical problem, the central rack of composite drilling cutting milling sample machine for laboratory use of the present utility model is installed removable worker's platform, drilling and milling unit head are installed in top, on described worker's platform anchor clamps are housed, described frame lower is supported with worker's platform and moves the driving screw mandrel, the nut that screws with described mobile driving screw mandrel is fixed on the worm gear case, worker's platform top panel is housed on the described worm gear case, in the horizontal worm gear of worm drive is housed, described worm gear is connected with internal gear is coaxial, described internal gear respectively with three uniform pinion, the top of described pinion is connected with three curve pieces that are positioned on the top panel respectively, form the three-jaw clamping structure around the worm gear axle center, the side of described curve piece is shaped on the cumulative curved profile in utmost point footpath.
Like this, when worm gear rotates under worm screw drives, will drive three pinions by internal gear and rotate synchronously, the result makes the curve piece that forms the three-jaw clamping structure dwindle interior zone gradually, by the effect of curved profile, fast the different shape sample on worker's platform top panel is clamped.Afterwards, under the driving of leading screw and nut mechanism, worm gear case is together with the workpiece move left and right, milling, under the effect of drill bit, in time finishing required drilling and drilling processing.
In order to reach further purpose, install respectively by the drilling of driven by motor and milling driven pulley the upper cross plate both sides of above composite drilling cutting milling sample machine for laboratory use frame, the middle lifting that driven by motor is installed drives screw mandrel, described drilling and milling driven pulley are connected with the cutter spindle of drilling and milling unit head by the spline mechanism at its center respectively, the knife bar axle sleeve of described drilling and milling unit head is fixed on the middle yoke plate, yoke plate constitutes vertical moving sets with upper vertical plate under being fixed on upper cross plate in described, and is fixed with the nut that screws with lifting driving screw mandrel.
Be understood that owing to arrange about drilling and milling unit head, therefore the workpiece on mobile worker's platform can switch fast, thereby satisfies the processing request that in time carries out drilling after the milling between two stations.Simultaneously, since drilling and milling unit head respectively by driven by motor, therefore be easy to obtain required low speed drilling and high-speed milling by control; And the elevating movement of drilling and milling unit head makes complete machine structure simple, compact by elevating screw nut body interlock control, and use in very suitable Metallographic Analysis laboratory.
This shows that the utility model mechanism configuration is ingenious, reasonable, coordinate each other, compactness, various profile sample workpieces of clamping rapidly, and realize workpiece bore, the miller position switches fast, thereby can satisfy the specific demand that laboratory sample is processed.
