Description

Multi-purpose machine

The utility model relates to a kind of family expenses lathe that can carry out car, brill, milling, that is, and and multi-purpose machine.

Develop multi-purpose machine product producer as taking the lead in, the series of products of having released are the same with the like product of other producer, technology becomes better and approaching perfection day by day, the quality quite stable, its basic structure still is the combination of engine lathe and drilling machine, but exist complete machine general layout to owe harmony, the range of work is less, main shaft speed change, belt swelling trouble, many weak points such as driving-chain long pass efficiency of movement is low, as Bangbu machine tool plant produce disclosed multi-purpose machine (Chinese patent: 87214113), its transmission chain length, transmission efficiency is low, and the manual drives planker vertically moves effort.

The purpose of this utility model is at the weak point in the above-mentioned prior art, design a kind of multi-purpose machine, it is big that it has the range of work, precision height, transmission efficiency height, turning and the swelling of brill milling belt are effective, and speed change is convenient, and manual drives slide carriage length feed is light, quick, the Drilling and milling head lift rotary, positioning and locking is laborsaving, convenient, reliable.

The purpose of this utility model is achieved in that multi-purpose machine, and it mainly comprises: Drilling and milling head case 1, column 2, knife rest 3, workbench 4, slide carriage 5, tailstock 6, slip crate 8, lathe bed 9, geared head 10, left socle 11 and transmission case 12.Under main frame, also be provided with two box-like bases 7 of group.

The lifting of Drilling and milling head case, revolution, positioning and locking device in the multi-purpose machine, be but that an elevating screw 14 is set on the column head 13 of plane rotation, by on the elevating screw 14 with Drilling and milling head case 1 on the secondary mechanism of bevel-gear sett, can make the Drilling and milling head case do oscilaltion.One screw rod 20 is set on Drilling and milling head case 1, two

nut block

21,22 clamping columns 2 that hand of spiral is opposite on the screw rod 20, rotating screw bolt 20 can make Drilling and milling head case 1 positioning and locking on column 2.

Bore milling belt take-up in the multi-purpose machine, be to mill increase by one counter wheel 28 between the belt wheel at electrical machine belt pulley 23 and brill, counter wheel 28 places on the eccentric shaft 29, adjusting along with the motor take-up, by belt 25, can change counter wheel 28 and bore the centre-to-centre spacing of milling belt wheel, make to bore and mill speed change, swelling, convenient, fast.

Multi-purpose machine middle slide carriage longitudinal feeding device, in the time of manually, lathe bed 9 upper racks 30 and gear shaft 31 engagements that are fixed on the slip crate 8, handwheel 34 is by a pair of gear pair gear shaft 31, to realize the slide carriage length feed.When motor-driven, then by screw mandrel 36, by two formula clasp nuts, the 35 driving slide carriage length feeds of partable.

Multi-purpose machine middle slide carriage length feed shift transmission, be in driving gear pair, being provided with one can be along the duplicate gear 40 of jackshaft 41 left and right slips, stir the movable block 39 that places between 40 liang of gears of duplicate gear, make the different gears engaged of duplicate gear 40 with upper level, can make the auto-feed shift, the range of work also expands and is twice.

Turning belt take-up in the multi-purpose machine, also be that increase by one counter wheel 53, counter wheel 53 are installed on the supporting plate 54 between electrical machine belt pulley and turning main shaft belt wheel, supporting plate 54 can rotate around the axle 55 that is fixed on the transmission case 12, and supporting plate 54 lower ends are connected with transmission case 12 by spring 56.During the belt swelling, spring 56 elongates stressed between counter wheel 53 and electrical machine belt pulley, and supporting plate 54 is rotated around axle 55 by the tension force effect, makes that belt is able to swelling between counter wheel 53 and turning main shaft belt wheel.Otherwise, under spring 56 restoring force effects, each belt slack, at this moment, replaceable belt changes rotating speed.

Owing to adopt such scheme, the complete machine layout is coordinated attractive in appearance, and the shortening of driving-chain has reduced noise, has improved transmission efficiency; Brill, the lifting of milling case are turned round, locate laborsaving, safe, reliable; The belt take-up makes main shaft speed change, driving belt swelling, easy to operate; The turning length feed, manual light and flexible, motor-driven clutch is fast reliable.
