Description

Double-drill-bit horizontal drilling machine

Technical Field

The utility model relates to a lathe field specifically is a double-drill horizontal drilling machine.

Background

An existing automobile spindle box often has a plurality of holes, for example, a hole to be machined 1' on the spindle box shown in fig. 1, a single-hole drilling machine is still used in the existing common method, and during operation, one hole is drilled first, and then a clamp or a drill bit is moved to perform second operation. However, no matter the clamp or the drill is moved, secondary positioning is often needed, so that the labor intensity is improved, the working efficiency is reduced, errors are large when drilling is carried out twice, the distance between two holes to be machined is difficult to guarantee, and the machining precision is reduced.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the technical problem that will solve lies in: often need secondary location, not only improve intensity of labour, reduce work efficiency, the error is great when also can lead to twice drilling moreover, is difficult to guarantee the interval between two holes of waiting to process, has reduced the machining precision.

In order to solve the technical problem, the utility model provides a following technical scheme:

a double-drill horizontal drilling machine comprises two guide rails, wherein a sliding block is arranged between the guide rails, the sliding block is driven by a screw rod matched with the sliding block and freely moves on the guide rails, and the screw rod is driven by an external driving device; the drilling machine is characterized in that a motor is arranged on the sliding block, a conversion box is arranged on one side of a main shaft of the motor, the main shaft is in transmission connection with two groups of output shafts through the conversion box, the distance and the position between the output shafts are matched with the distance and the position between holes to be machined, and a drill bit is installed on the output shafts.

As a further aspect of the present invention: the driving gear connected with the main shaft is arranged in the conversion box, the driven gears connected with the output shaft are further arranged in the conversion box, and the driving gear is meshed with the two groups of driven gears respectively.

As a further aspect of the present invention: the driven gears are the same size.

As a further aspect of the present invention: the upper end of the conversion box is a detachable top cover.

As a further aspect of the present invention: the end part of the output shaft is fixedly provided with a drill bit seat, and the drill bit is detachably connected with the drill bit seat.

As a further aspect of the present invention: the drill bits are the same length.

As a further aspect of the present invention: the motor is a stepping motor or a servo motor.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses can realize two while drilling of treating the machined hole of headstock, not need the secondary location, not only reduce intensity of labour, improve work efficiency, also reduce machining error moreover, guarantee the machining precision.

Fig. 2 is a schematic structural diagram of the embodiment.

In the figure: 1 '-a hole to be processed, 2' -a through hole, 1-a guide rail, 2-a slide block, 3-a screw rod, 4-a motor, 5-a main shaft, 6-a conversion box, 7-an output shaft and 8-a drill bit.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, a double-drill horizontal drilling machine comprises two guide rails 1, wherein a sliding block 2 is arranged between the guide rails 1, the sliding block 2 is driven by a screw rod 3 matched with the sliding block and freely moves on the guide rails 1, and the screw rod 3 is driven by an external driving device; the drilling machine is characterized in that a motor 4 is arranged on the sliding block 2, a conversion box 6 is arranged on one side of a main shaft 5 of the motor 4, the main shaft 5 is in transmission connection with two groups of output shafts 7 through the conversion box 6, the distance and the position between the output shafts 7 are matched with the distance and the position between holes 1' to be machined, and a drill bit 8 is arranged on the output shafts 7.

As an optional scheme, a driving gear connected with the main shaft 5 is arranged in the conversion box 6, driven gears connected with the output shaft 7 are further arranged in the conversion box 6, and the driving gear is respectively meshed with the two groups of driven gears.

Alternatively, the driven gears are the same size.

Optionally, the upper end of the conversion box 6 is a detachable top cover.

Optionally, a drill bit seat is fixedly arranged at the end of the output shaft 7, and the drill bit 8 is detachably connected with the drill bit seat.
