Abstract
The utility model provides a variable speed drilling-tapping amphibious machine, belonging to the mechanical skill. The utility model solves the present trouble of assembling, disassembling and servicing of the variable speed drilling-tapping amphibious machine. Meanwhile, the problems that the speed reducing member limits speed reducing ratio and always hinders the view of the operator are also solved. The utility model comprises a base, and a pillar fixed on the base. And the pillar is equipped with an electric motor, a transmission member, a spindle, and the speed reducing member. So the electric motor can turn the spindle through the transmission member, while the speed reducing member is positioned between the motor and the transmission member. The speed reducing member is a underdriving gear set. The transmission member comprises a driving pulley positioned on the rotating shaft of the electric motor, a driven pulley positioned on the input shaft of the underdriving gear set and a belt connected with the driving pulley and the driven pulley. The variable speed driving-tapping amphibious machine has the advantages of easy operation and maintenance, higher speed reducing ratio, convenient operation and low cost.
Description
Technical field
The utility model relates to a kind of drilling machine, and the brill that relates in particular to a kind of variable-ratio is attacked convertible drilling machine, belongs to field of mechanical technique.
Background technology
Drilling machine can be holed or tapping processing to workpiece, and drilling machine is being holed to workpiece or during tapping, and the velocity of rotation that is used to install the main shaft of drill bit or screw tap on the drilling machine is different; When boring, require the velocity of rotation height of main shaft, when tapping, require the velocity of rotation of main shaft low, therefore, on drilling machine, also need to be provided with reducing gear and switching mechanism, be used for the switching of main shaft between high speed and low speed.Reducing gear on the existing drilling machine is arranged on the bottom of main shaft, and the drilling machine of this structure has its defective: 1, maintenance mounting or dismounting trouble.2, be subjected to the restriction of main shaft mount pad overall dimensions, under the speed of permission running, the speed reducing ratio of reducing gear can not be very big, and the function of drilling machine has certain limitation.3, drilling machine in the course of the work, reducing gear also can hinder operator's sight line, this can have influence on operator's Job Operations.
Summary of the invention
The purpose of this utility model is to bore at existing variable-ratio to attack the problems referred to above that convertible drilling machine has, provide a kind of novel variable-ratio to bore and attack convertible drilling machine, it is convenient that it has the maintenance mounting or dismounting, the excursion of the speed of mainshaft is big on the drilling machine, drilling machine is convenient to operation in the course of the work, can not increase the advantage of drilling machine manufacturing cost.
The purpose of this utility model can realize by following technical proposal: a kind of variable-ratio bores attacks convertible drilling machine, comprise base, be fixed in the column on the base, on column, be provided with motor, transmission mechanism, main shaft, reducing gear, motor drives main shaft by transmission mechanism and rotates, it is characterized in that described reducing gear is located between transmission mechanism and the main shaft.
Described main shaft and reducing gear link, and generally also need to be provided with a switching device shifter on the reducing gear.When drilling machine adds man-hour in that workpiece is holed, the power on the motor is directly delivered on the main shaft without reducing gear, and the velocity of rotation of main shaft is fast.And add man-hour when drilling machine need carry out tapping to workpiece, and the operation switching device shifter participates in the process of transmission of power reducing gear, and the velocity of rotation of main shaft is low, and driving torque is big.Reducing gear generally is arranged in the casing of a sealing, and this casing is arranged on the top of main shaft mount pad, and main shaft directly is connected on the casing.
Attack in the convertible drilling machine at above-mentioned variable-ratio brill, described main shaft is perpendicular to the base setting, and described reducing gear is located at the top of main shaft.Reducing gear directly links with transmission mechanism, and the casing that main shaft mount pad and being used to is installed reducing gear is fixed together, and the top attachment of main shaft is in reducing gear.
Attack in the convertible drilling machine at above-mentioned variable-ratio brill, described reducing gear is a train of reduction gears.The different-diameter in the train of reduction gears and the gear of modulus are meshing with each other together, make train of reduction gears when participating in transmission of power, can reduce the rotating speed by institute's transferring power on the transmission mechanism.
Bore at above-mentioned variable-ratio and to attack in the convertible drilling machine, described transmission mechanism is driving pulley, the driven pulley on the train of reduction gears power shaft on the machine shaft and connects belt on above-mentioned two belt wheels.The outputting power of motor is exported by machine shaft, and the belt pulley on the belt pulley on machine shaft, belt, train of reduction gears power shaft and being delivered in the train of reduction gears.
Compared with prior art, the beneficial effects of the utility model are:
1, because reducing gear is located between the main shaft and transmission mechanism of drilling machine, and when maintenance, only the cover plate that need remove on the deceleration box can be realized, and does not need to dismantle the main shaft mount pad, maintenance operation is convenient.
2, the set position of reducing gear can not be subjected to the restriction of main shaft mount pad size and working environment, and power can obtain bigger speed reducing ratio after via the deceleration of reducing gear, can satisfy the real work demand of drilling machine.
3, the position of reducing gear setting also can not have influence on operator's sight line, is convenient to the smooth operation of drilling machine.
4, the just variation of reducing gear position setting in this drilling machine is compared with existing drilling machine, and its cost is constant.
