Abstract
The utility model discloses a multi-function electric drill, adopting a common hand held electric drill to appropriately combine components as a multifunction electric power tool provided with positioning drilling and wringing and positioning sawing. The multi-function electric drill is mainly characterized in that through the combination and the extended function of a cogging-shaped rack and the component or through the separation of the cogging-shaped rack and the component, the primary function and characteristic of the common electric hand drill is resumed, and the multifunctional and universal effect is achieved.
Description
The utility model relates to a kind of multifunction drill, particularly becomes through appropriate combination with common electric hand drill to have that the location drills and reams, the multi-functional electric tools of orientation cutting and grinding.
Electric hand drill has only single boring function at present, and borehole accuracy is not high.Though and common bench drill can improve borehole accuracy, its weight generally has about 60 kilograms, is difficult to carry, and its function still has only boring or reaming etc.Many little workshops or REPSH repair shop all be unable to do without drill and ream, operation such as cutting and grinding, because of economics dictate, can not too much purchase the electric tool of simple function, utility model 88211072 is introduced a kind of combined multipurpose bench drill, though its weight is lighter than common bench drill, its function is expanded to cutting mill, throwing etc. by boring, but still functions such as shortcoming orientation cutting and grinding, do not satisfy the needs of little workshop or the common operation of REPSH repair shop, and its structure is still complicated, cost is higher, is difficult to generally apply at little workshop or REPSH repair shop.Consider from the ratio of performance to price and use value, press for a kind of combined multifunctional electric tool on the market.
The purpose of this utility model is the power that utilizes common electric hand drill to provide, become through appropriate combination and to have that the location drills and reams, multi-functional electric tools such as orientation cutting and grinding, not only make electric tool but also make junior machine and use, and still keep the easy to carry of electric hand drill, advantage simple to operate.
The utility model adopts following design realization above-mentioned purpose, promptly based on common electric hand drill basic structure, mixes simple and easy stand, increases a little sub-assemblies and constitutes multi-functional electric tools.Its main part comprises electric hand drill (5), crossbeam (7), control stick (6), base (1), workbench (2) and column (10), its add-on assemble has the tenon shape tooth bar (31) that is fixed in the electric hand drill back and engages perpendicular to the terminal tenon shape teeth groove (38) of crossbeam (7), and the hook spring (9) that is fixed in the middle part of the crossbeam by lifter wheel (a 32) bar shaped alignment pin (37) and an end is combined into the location drilling device; Form grinding attachment by electric drill rotating shaft (3), belt pulley (4), belt pulley (14) and sand (pawl) wheel disc (13).The tenon shape tooth bar (31) at electric hand drill back and stationary rack pawl (25) engagement are combined into positions saw, are cut device by electric drill rotating shaft (3), drive (24), crank (26), power transmission shaft (27) and chuck mouth (23).Add-on assemble need be assembled at any time, dismantle to finish various processing operations by operation.
Concrete structure of the present utility model is provided by the following drawings and embodiment.
Fig. 1 is a multifunction drill basic structure schematic diagram.
Fig. 2 is assembled into saw, cuts the positioner schematic diagram.
Fig. 3 is when being assembled into location drilling, grinding attachment, the engagement of tenon shape tooth bar lifter wheel, the part cutaway view that engages with tenon shape teeth groove.
(1) base among the figure, (2) workbench, (3) electric drill rotating shaft, (4) belt pulley, (5) electric hand drill, (6) control stick, (7) crossbeam, (8) spring fastening nut, (9) spring, (10) column, (11) crossbeam clamping lever, (12) sand (pawl) wheel nut, (13) sand (pawl) wheel disc, (14) belt pulley, (15) needle beam, (16) sand (pawl) wheel shaft, (17) needle beam clamping lever, (18) column hold-down screw; (21) hand trigger piece, (22) saw blade, (23) chuck mouth, (24) drive, (25) stationary rack pawl, (26) crank, (27) power transmission shaft, (28) locating rack cover, (29) position fixing handle; (31) tenon shape tooth bar, (32) lifter wheel, (33) gear shaft, (34) gear key, (35) beam-ends, (36) lifting tooth race, (37) bar shaped alignment pin, (38) tenon shape teeth groove.
Below in conjunction with accompanying drawing structure, connection and the course of action of embodiment are done summary description.
Device when Fig. 1 represents to be assembled into boring and grinding inserts the transverse arm end with electric hand drill, makes lifter wheel (32) engagement of tenon shape tooth bar (31) with the fixed cross beam end at electric hand drill back, engages with tenon shape groove (38).Bar shaped alignment pin (37) is inserted between tenon shape teeth groove (38) and the tenon shape tooth bar (31).Make chucking tenon shape tooth bar (31) lower end, hook spring (9) lower end.Regulate the relative position of crossbeam clamping lever (11) and workbench (2) and tighten up, can control drilling accuracy, control stick (6) control drill bit progress, the elastic force of hook spring lower end provides constraints, when tenon shape tooth bar apical tooth is reduced to tenon shape teeth groove mid point, because the elastic force of hook spring restriction drill bit moves on.
When being combined into mill (cutting) device, the tenon shape tooth bar at electric hand drill back still engages with tenon shape teeth groove perpendicular to beam-ends, link to each other by chuck by electric drill rotating shaft (3) and belt pulley (4) axle and to tighten up, regulate the relative position of needle beam (15), make belt pulley (14) and belt pulley (14) be in same horizontal plane, tighten up needle beam (15) and grinding wheel spindle (16), belt pulley (14) also is fixed with sand (pawl) wheel disc (13).Grind or cut respectively with abrasive disc or ratchet wheel dish.
Fig. 2 represents to be assembled into saw with electric hand drill, when cutting device, the annexation of annex, drive (24) axle tightens up by the chuck of electric drill rotating shaft (3) is continuous, crank (26) one ends are fixed at the drive plate edge, the other end is fixed on the middle part of power transmission shaft (27), power transmission shaft one end has the chuck mouth (23) of fastening saw blade (or cutter), power transmission shaft is located by locating rack cover (28), position fixing handle (29) one ends are fixing by the locating rack cover, the other end is meshed with electric hand drill back tenon shape tooth bar (31) by stationary rack pawl (25), when starting, become the reciprocating motion of saw blade by the circular motion of electric drill rotating shaft.
Electric hand drill cooperates expanded function by its tenon shape tooth bar with other assemblies, also separates with crossbeam with the bar shaped alignment pin by tenon shape tooth bar, and recovers the original function of electric hand drill and characteristics, reaches multi-functional and unitized effect.
