Abstract
A rechargeable electric drill with a tool box integrated on its back is composed of front and back casings, directional knob, switch, battery bay, force moment regulator, and power driver consisting of motor and gear chain. It features that its tools can not be lost easily.
Description
The present invention relates to a kind of rechargeable electric tool, particularly have the instrument cases of storing drill bit or rotating tool head function, it becomes chargeable electrodrill with drill tips box after can making up with Charge).
Existing commercially available and use electric drill, its instrument and drill bit are separately to deposit, take care of, and the time spent, have taken electric drill to go for drill bit again, drill bit often takes place lose the phenomenon that can not find, and use, carry all inconvenient.Especially open-air work high above the ground is used more inconvenient.On one's body the operator also need take the drill bit of various different sizes to, when changing drill bit aloft, accidentally, drill bit also will climb down and seek from dropping to the ground in the air, has influenced work, brings many worries to the operator again.
The object of the present invention is to provide a kind of chargeable electrodrill with drill tips box, can deposit drill bit or rotating tool head in the instrument cases, after electric drill combination, carry, easy to use, improved operating efficiency.
The present invention be achieved in that chargeable electrodrill with drill tips box by commutation button, switch, power brick, torque adjusting device are installed in forward and backward housing, the powered rotation device is formed, and described actuating unit is fixed on the bonnet by motor and gear-box, the output shaft of gear-box links into an integrated entity with the main shaft of band transposition gear, and by the engagement of the output gear on transposition gear and collet axis formation, Charge) housing back is equipped with instrument cases, arbitrarily dismounting.
Fig. 1, structural representation of the present invention (taking away fore shell).
The A-A view of Fig. 2, Fig. 1.
The B-B view of Fig. 3, Fig. 1.
The C-C view of Fig. 4, Fig. 1.
Below in conjunction with accompanying drawing embodiments of the invention are further described:
Procapsid (27), back casing (26) be symmetry substantially, reinforcement, joint pin, posting etc. are arranged on the inwall, the installing hole of adjusting nut (12), switch (24), commutation button (23) is arranged on the outer surface, on upper end one sidewall of procapsid (27), back casing (26) gathering sill (9) is arranged.
The cross section of instrument cases box body (3) is circular, periphery has equidistant 8 through holes, be used to lay drill bit or the rotating tool head of φ below 6 * 90 millimeters, end has counterbore to be placed with spring steel ball (7), it is that steel ball spring (7) location is used that box shell (5) inner face has 8 shallow bore holes, box shell (5) outer face has eccentric orfice can be connected collet axis (16) endoporus respectively with 8 through holes of box body (3) to communicate, respectively there is spring positioning key (4) box shell (5) lower limb both sides, respectively there is viewing hole (2) on (3) 8 openings limits of box body, box body (3) slides on the central shaft of box shell (5), is lived by the fixing shelves of lid (1).
In the middle of the collet axis (16) is through hole, and appearance is straight spline, and the cylindrical kink the nut of setting one's teeth on edge (17).
Actuating unit is fixed on the bonnet (8) by direct current generator (6) and gear-box (10), motor shaft is connected with gear in the gear-box (10), the output shaft of gear-box (10) links into an integrated entity with the main shaft (19) of band transposition gear (20), and goes up output gear (14) the engagement composition that tape spool holds (15) by transposition gear (20) and collet axis (16).Drill chuck is fixed on the collet axis (16) with screw thread, and goes up the outer locking that is threaded with nut of setting one's teeth on edge (17) and drill chuck (18).
Centring ring (21) on the annular of uniform through hole is arranged, inner ring is a splined hole.
The torque adjusting device is by being placed with steel ball (11) (1-2 grain) and spring (13) at the breach of regulating sleeve (22) and with gear-box (10) junction, inner face at regulating sleeve (22) is embedded with a steel ball, steel ball is transferred centring ring (21), connects adjusting nut (12) outward again and forms.
The main shaft (19) that the torque adjusting device is installed in actuating unit upward is connected one with it, drill chuck (18) is put into back casing (26) together with collet axis (16), bearing (15), output gear (14), switch (24), commutation button (23), cover procapsid (27), connect one with screw, put into power brick (25) again and form Charge), then with instrument cases till gathering sill (9) is pushed forward to positioning key (4) locking.Promptly form chargeable electrodrill with drill tips box.
Unclamp drill chuck (18) pinch, required drill bit enters in the instrument cases box body (3) through collet axis (16) intermediate throughholes and deposits, what a is put changes an angle with box body (3) again, continues then to put into drill bit from the intermediate throughholes of collet axis (16), enters in the box body (3) and deposits.And the like, and, make the interior drill bit of box body (3) be in closed state with 0 of box body (3) groove aligning, prevent to pour out (deposit drill bit and also instrument cases can be removed, directly deposit separately) from the inside.Earlier choose required drill bit during use from viewing hole (2), rotate box body (3) then, aim at and carve wire size, then that the electric drill front end is downward-sloping, drill bit is in the sliding only drill chuck of collet axis (16) intermediate throughholes, make its chucking, at this moment Push switch (24), motor (6) rotates, and drives main shaft (19) and rotates, by the transposition gear (20) on the main shaft (19), make output gear (14) rotation with its engagement, the drill chuck (18) that just drives the collet axis (16) on it and have a drill bit rotates and to carry out work, and work finishes, trip switch (24), motor (6) stops operating, drill chuck (18) stops operating, unclamp drill chuck (18) pin, the electric drill front end is inclined upwardly, and drill bit slides in the box body (3) from collet axis (16) intermediate throughholes and deposits, and the like, finish as work, forward box body (3) groove to 0, avoid drill bit from instrument cases, to drop out.
But clockwise direction rotates adjusting nut (12) and compresses regulating sleeve (22) and spring (13), and output torque is increased, and then moment diminishes on the contrary.
The present invention compares with existing: can deposit drill bit or rotating tool head because there are instrument cases at the electric drill back, all the time drilling tool is had drilling tool and Electric drill is kept at together, can not lose the phenomenon with the look round for drill bit, uses, easy to carry. Especially be the work of ascending a height The user of industry provides the more easily instrument that uses, and loading and unloading, transposing drill bit conveniently drill bit can not take place from falling down in the air Phenomenon, alleviated labour intensity, saved the time, improved operating efficiency.
