Abstract

The utility model discloses a dual-purpose boring and tapping drill press, comprising a motor(1) and a headstock(9). A driving wheel(2) is connected on the motor(1) and is connected with a driven wheel(3)through a belt; a tapping principal shaft(5) is sleeved at the driven wheel(3), and a secondary driven wheel(4)is connected with the driven wheel through a belt; a boring principal shaft(6)is sleeved with the secondary driven wheel(4); and the driving wheel(2), the driven wheel(3) and the secondary driven wheel(4) are sequentially arranged at the centerline of the headstock(9). The boring and tapping drill press adopts double principal shafts and can reach the purposes of both boring and tapping on the same drill press without changing an aiguille. The volume of the drill press is not increased, and the dual-purpose boring and tapping drill press is compact in structure and small in occupying area. A taping handle and a boring handle are respectively arranged at two sides of the headstock, thus avoiding collision of the taping handle and the boring handle when in use in a limited room. Therefore the taping handle and the boring handle have no interference to each other, thus convenient to use.

Description

The drilling and tapping convertible drilling machine

Technical field

The utility model relates to a kind of drilling and tapping convertible drilling machine, belongs to the drilling machine technical field.

Background technology

Present employed drilling machine is taked single main shaft form, and this drilling machine continues tapping operation if desired after carrying out drilling operation, then workpiece will be taken off, and bit change perhaps is put into the operation of getting on of an other drilling machine that threading drill bit is installed.Because bit change more, and behind bit change more to the steady job of workpiece, can spend many manpowers and time, so operating efficiency is greatly affected, problem has to be solved.

The utility model content

Technical problem to be solved in the utility model is, providing a kind of does not need to change drilling machine or drill bit can be holed and the convertible drilling machine of tapping operation.

The technical solution of the utility model: the utility model comprises motor 1 and main spindle box 9, be connected with driving wheel 2 on the motor 1, driving wheel 2 is connected with driven pulley 3 by belt, be socketed with tapping main shaft 5 on the described driven pulley 3, driven pulley 3 also is connected with time driven pulley 4, inferior driven pulley 4 socket drill spindles 6 by belt; Driving wheel 2, driven pulley 3 and inferior driven pulley 4 are arranged in a straight line successively on main spindle box 9 center lines.

Described tapping main shaft 5 is connected with tapping lowering or hoisting gear 10, and drill spindle 6 is connected with boring lowering or hoisting gear 11, is respectively applied for tapping main shaft 5 and controls with the lifting of drill spindle 6.

Described tapping lowering or hoisting gear 10 is connected with tapping handle 7, and boring lowering or hoisting gear 11 is connected with boring handle 8, and tapping handle 7 and boring handle 8 lay respectively at the both sides of main spindle box 9.

Described driving wheel 2, driven pulley 3, inferior driven pulley 4 are pulley concial disks.

The utility model is by being provided with tapping main shaft and drill spindle respectively in the main spindle box of original bench drill, adopted the structure of two main shafts, making is not needing under the situation of bit change more, just can reach on same bench drill and both hole, carry out the purpose of tapping again, and do not increase the volume of original drilling machine, the arrangement architecture compactness, it is little to take up space.Tapping handle and boring handle are separately positioned on the both sides of main spindle box in addition, just can avoid both collisions in use in limited space, thereby mutually noninterfere are easy to use.

Accompanying drawing 2 is the utility model plan structure schematic diagram.

The specific embodiment

Embodiment of the present utility model: structure of the present utility model as shown in Figure 1 and Figure 2, comprise motor 1 and main spindle box 9, be connected with driving wheel 2 on the motor 1, driving wheel 2 is connected with driven pulley 3 by belt, be socketed with tapping main shaft 5 on the described driven pulley 3, driven pulley 3 also is connected with time driven pulley 4, inferior driven pulley 4 socket drill spindles 6 by belt; Driving wheel 2, driven pulley 3 and inferior driven pulley 4 are arranged in a straight line successively on main spindle box 9 center lines.Tapping main shaft 5 is connected with tapping lowering or hoisting gear 10, and drill spindle 6 is connected with boring lowering or hoisting gear 11, is respectively applied for tapping main shaft 5 and controls with the lifting of drill spindle 6.Tapping lowering or hoisting gear 10 is connected with tapping handle 7, and boring lowering or hoisting gear 11 is connected with boring handle 8, and tapping handle 7 and boring handle 8 lay respectively at the both sides of main spindle box 9.Driving wheel 2, driven pulley 3, inferior driven pulley 4 are pulley concial disks.

In use, earlier workpiece is fixed on the fixed station, places the below of drill spindle 6, shake boring handle 8, descend, realize drilling operation by boring lowering or hoisting gear 11 keyhole main shafts 6.After boring is finished, shake boring handle 8, rising drill spindle 6, the fixed station of fixation workpiece by move at the slide rail that is provided with on the Drilling machines bench tapping main shaft 5 below, shake tapping handle 7, descend, carry out tapping by tapping lowering or hoisting gear 10 control tapping main shafts 5.After tapping is finished, shake tapping handle 7, rising tapping main shaft 5 is so far finished boring and tapping operation, and is very simple.Wherein, tapping speed is slower than penetration rate.
