Abstract

The utility model provides an electric drill support, which is characterized in that the electric drill support is composed of a soleplate 10 with a work hole 6 and a pillar base 8, a pillar 19 arranged in the pillar base 8, a spring 9 sheathed out of the pillar 19, a sleeve barrel 18 with a clamp ring 13, a head clip 4 which is connected with lower end of the sleeve barrel 18 via a transverse rod 5, a rail clip 16 which is sheathed out of the sleeve barrel 18 and is provided with a pressing plate 15, a connecting rod 11 which is hinged with edges of the soleplate 10 and a feeding handle 1 which passes through the sleeve barrel clamp ring 3 and is hinged with the connecting rod 11. The handle 1 is sheathed with a spring 14 between the clamp ring 13 and the connecting rod 11. The utility model can rapidly and simply clamp and install electric drills with various types and standards and can conveniently drill holes in plane surfaces, vertical surfaces and top surfaces.

Description

Electric drill support

The utility model relates to a kind of support, and particularly a kind of Electric drill support uses for the various electric drills of clamping are installed.

At present, various electric drills (comprising percussion drill, hydraulic pressure brill etc.) all are operations dominated by hand, and labour intensity is big, poor stability, and accuracy is low, is easy to the drill bit that fractures.

The purpose of this utility model provides a kind of Electric drill support that the electric drill clamping quickly and easily of various model specifications can be installed and carried out easily plane, facade and end face drilling operation.

Electric drill support of the present utility model, it is characterized in that its base plate by band working hole and column base, be installed in the column in the column base, be enclosed within the outer spring of column and the sleeve of band clasp, be connected a clip of sleeve lower end through cross bar, be enclosed within outside the sleeve, the tail clip of band pressing plate, the connecting rod hinged with bottom edge passes the sleeve snap ring and forms with the feeding handle of rod hinge connection; Handle is with spring between snap ring and connecting rod; Have keyway on the column, have key to cooperate with it in the sleeve.

More reliable when using and using for the electric drill that can adapt to the different size model, safety, Electric drill support of the present utility model also are provided with annexes such as hoop sleeve, crumb loading cover, platter, stern post.

Electric drill support of the present utility model can be installed the electric drill clamping quickly and easily of various model specifications, on the plane, inclined-plane, facade and end face can both operate by fringe surely, reduces labor intensity, increase work efficiency and borehole accuracy, owing to set up annex, opened up the multiple function of use that has increased electric drill.

Describe the concrete structure and the course of work of the utility model Electric drill support in detail below in conjunction with accompanying drawing.

Fig. 1 is the schematic diagram of the utility model Electric drill support.

Fig. 2 is the accessory part figure of the utility model Electric drill support.

Among the figure, the 1st, feeding handle, the 2nd, electric drill, the 3rd, a clip fishbolt, the 4th, a clip, the 5th, a clip cross bar, the 6th, base plate working hole, the 7th, column trip bolt, the 8th, base plate column base, the 9th, sleeve back-moving spring, the 10th, base plate, the 11st, connecting rod, the 12nd, stop screw, the 13rd, sleeve snap ring, the 14th, lever back-moving spring, the 15th, tail clip pressing plate, the 16th, tail clip, the 17th, tail clip fishbolt, the 18th, sleeve, the 19th, column, the 20th, column pin-and-hole, the 21, the 22nd, hoop sleeve, the 23rd, crumb loading cover, the 24th, platter, the 25th, stern post.

When electric drill is installed, the front cover shell of electric drill 2 is stretched into a clip 4 downwards, drill bit is over against the working hole 6 of base plate 10, tappet head clip butterfly or hex nut 3, the shaft bearing seat position of electric drill 2 is clamped, compress the rear casing of electric drill 2 with the pressing plate 15 of tail clip 16, tighten tail clip butterfly or hex nut 17, electric drill 2 just is fixed on the sleeve 18, the interior circle of sleeve 18 cooperates with the cylindrical of column 19, sleeve 18 can endwisely slip along column 19, on the keyway of column 19 and the sleeve 18 interior circles, the key of lower end cooperates, and makes between sleeve 18 and the column 19 and can not rotate, feeding handle 1 passes the snap ring 13 that is fixed on the sleeve 18, hinged with connecting rod 11, connecting rod 11 is hinged with base plate 10 again, presses fixed handle 1, the electric drill 2 that just can drive sleeve 18 and be clamped on the sleeve 18 is done the boring feeding, release handle 1 relies on the acting in conjunction of sleeve back-moving spring 9 and lever back-moving spring 14, and drill bit withdraws from boring.

In the annex, hoop sleeve 21,22 cylindrical portion cooperates with the interior circle of a clip 4, and interior circle has different diameters, clip 4 is not put hoop sleeve or is put into different hoop sleeves, just can adapt to the electric drill front cover shell of different size model and with its clamping, when carrying out the end face drilling operation, crumb loading cover 23 is installed between a clip 4 and the base plate 10 drill bit cover post, can avoid dust to be splashed to operator's head, face, in relatively-stationary workplace, fixing hole by base plate 10 support is installed in plate and on, its stability is as good as with bench drill, if replace base plate 10 with platter 24, support is more light, also available binding clip is clipped in the platter 24 of support on the working face, then use similar very valuable magnetic drill press, just need hand feed, the cylindrical of stern post 25 cooperates with the interior circle of column 19, length is on demand inserted the part of stern post 25 in the column 19, pass both perforation pin-and-holes fixes with pin, then when boring the end face hole, support stern post 25 can be supported on falsework or the double ladder, save manpower and prop up the crown drill hole.

In an embodiment, the utility model seamless steel pipe processing and manufacturing tail clip 16, sleeve 18, column 19 and stern post 25, make crumb loading cover 23 with plastic telescopic pipe, all the other all use the processing and manufacturing of A3 steel, base plate 10 thick 10mm wherein, platter 24 and pressing plate 15 thick 4mm, the internal diameter of column base is 18mm, the external diameter of column is 18mm, the interior external diameter of sleeve is respectively 18mm and 23mm, the garter spring internal diameter of tail clip 16 is 23mm, the long 518mm of column, cover tube length 320mm, column base center and working hole centre distance are 85mm, note its relation of cooperatively interacting, base plate 10 between each part, 24 and column base 8 between, between sleeve 18 and cross bar 5 and the snap ring 13, between a cross bar 5 and the clip 4, all adopt electric welding to be connected between tail clip 16 and the pressing plate 15, handle 1 and connecting rod 11, connecting rod 11 and base plate 10, hinged employing bolt between 24.
