Abstract

The utility model discloses a multifunctional combined drill, which comprises a gearbox body; a central shaft is arranged in the gearbox body; a plurality of driven shafts are arranged in the gearbox body in a ring-shaped way; one end of each driven shaft is connected with a drill clamp; and the central shaft is in transmission connection with the driven shafts. The utility model disperses power on a main shaft of a drill machine to the central shaft mounted in the gearbox body, so that a plurality of drill bits can rotate simultaneously, and the purposes of clamping a plurality of cutters at one time and processing a plurality of workpieces at the same time can be achieved. The multifunctional combined drill of the utility model is convenient in cutter clamping and simple in installation and maintenance, can be used in coordination with the prior drill machine, and increases the efficiency by 5 times.

Description

A kind of multi-functional combination drill

Technical field

The utility model relates to a kind of drilling tool, relates to the multi-functional combination drill on a kind of drilling machine specifically.

Background technology

Drilling machine is as a kind of processing equipment, along with continuing to increase of production demand, for production more products in the identical time, enhance productivity to reduce cost, only take to strengthen factory, increase equipment and number of workers, when output improves, also strengthened the input of production cost and management cost, traditional drilling machine generally all is once can only drill bit of clamping, production efficiency is lower, has so not only wasted resource but also has increased workman labour.

The utility model content

Problem to be solved in the utility model is in order to overcome the deficiency of existing drilling tool, a kind of multi-functional combination drill that can process a plurality of parts simultaneously to be provided, can enhancing productivity, reduce labor strength.

In order to address the above problem, the technical solution adopted in the utility model is:

A kind of multi-functional combination drill comprises gear housing, is provided with central shaft in the described gear housing, is provided with some driven shafts in gear housing ringwise, and an end of described driven shaft is connected with drilling attachment, and described central shaft and driven shaft are in transmission connection.

Below be the utility model for further improvement of these options:

On the described central shaft driving wheel is installed, driven pulley is installed on the driven shaft, be provided with jackshaft between central shaft and the driven shaft, be provided with breast wheel on jackshaft, breast wheel is connected respectively with driven pulley with driving wheel.

Further improve:

Described driven shaft is the six roots of sensation, and jackshaft is three, and one group in twos of the driven pulley on the described six roots of sensation driven shaft is in transmission connection by breast wheel and driving wheel on jackshaft wherein respectively.

Further improve:

Described drilling attachment comprises the chuck that is installed on the gear block, is provided with chuck nut in the end of chuck, in chuck and chuck nut drill bit is installed, and described driven pulley is provided with counterbore near an end of chuck, and the afterbody of described drill bit is positioned at counterbore.

The utility model adopts such scheme, and when central shaft rotated, the moment of torsion of output was delivered on three breast wheels, and moment of torsion is delivered on three groups of driven pulleys by three breast wheels simultaneously, and driven pulley drives 6 drill bits of driven shaft rotation drive and rotates at a high speed.

The utility model adopts gear drive, with the power decentralized on the drill press spindle to the central shaft that is installed in the gear-box, a plurality of drill bits are rotated simultaneously, thereby reach a plurality of cutters of clamping No. one time, process the purpose of a plurality of workpiece simultaneously, the multi-functional combination drill clamping of the utility model cutter is convenient, installation and maintenance simple, can with the supporting use of existing drilling machine, effect can be brought up to original 6 times.

Below in conjunction with drawings and Examples the utility model is further specified:
