Advantage of the present utility model and good effect are: four hole drills of the present utility model are by arranging four drill bits, realized the operation in four holes of disposable brill, both promoted the positional precision between boring, and saved again in the operation of metal lining out, location and promoted drilling efficiency.The setting of handwheel, leading screw, guide pillar, has promoted the convenience that base plate moves up and down, and is convenient to material loading and the material returned.
Preferably: on described installing plate, be also connected with vertical gripper shoe, be connected with the pedestal of level in described gripper shoe, described reductor is installed on described pedestal.
Preferably: the left and right sides at described installing plate is equipped with fixed head, described the first axle bed and the second axle bed are installed on described fixed head.
Preferably: at the middle part of described plate upper surface, be also provided with metallic plate is carried out to spacing limiting tool.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, reductor; 2, pedestal; 3, gripper shoe; 4, fixed head; 5, installing plate; 6, the second axle bed; 7, guide pillar; 8, leading screw; 9, the first axle bed; 10, handwheel; 11, chain; 12, gear-box; 13, base plate; 14, drill bit; 15, limiting tool.
The specific embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples and be described in detail as follows:
Refer to Fig. 1, the utility model comprises the installing plate 5 that is positioned at top and the base plate 13 that is positioned at below, between both four jiaos, is equipped with guide pillar 7, and the top of guide pillar 7 and installing plate 5 are affixed, bottom is inserted in the axle sleeve being arranged on base plate 13.During practical operation, base plate 13 moves up with metallic plate, and four guide pillars 7 have guaranteed the stability of moving on base plate 13.
Between installing plate 5 and base plate 13, be also provided with top, two of left and right with the leading screw 8 of bevel gear, on leading screw 8, be provided with screw, this screw and base plate 13 are affixed.By driving leading screw 8 rotations, base plate 13 moves up and down.
In the left and right sides of installing plate 5, be respectively equipped with the first axle bed 9 and the second axle bed 6, on two axle beds, be provided with the rotating shaft of the inner bevel gear being meshed with the bevel gear with leading screw 8 tops, outer end in rotating shaft is equipped with sprocket wheel, between two sprocket wheels, be provided with chain 11, the outer end of a rotating shaft is also provided with handwheel 10 therein.In this example, in the left and right sides of installing plate 5, be equipped with fixed head 4, the first axle beds 9 and the second axle bed 6 and be installed on fixed head 4 separately.Now on fixed head 4, axle sleeve should be set, the upper end of leading screw 8 is positioned at axle sleeve, and the bevel gear at its top stretches out from this axle sleeve.By shaking handwheel 10, chain-driving sprocket rotation, bevel gear driving leading screw 8 rotations of rotating shaft the inner.
