Abstract

An elbow drill belongs to the technical field of metal machining and particularly relates to an electric hand drill in which the boring direction and a power output shaft form an angle of 90 DEG. A bearing support is installed at a power output end of a motor, a power output shaft of the motor is extended to the outer side of the bearing support, radiating fans are installed on the inner side of the bearing support and the power output shaft between a bearing and the motor, a driving cone gear is fixed at the top end of the power output shaft, a gear box is installed at the front end of the bearing support, and a driven cone gear vertical to the driving cone gear is installed in the gear box and engaged with the driving cone gear fixed at the power output shaft end. The utility model has the advantage of achieving the goal that the direction of the power output shaft of the motor and the drilling direction of a drill bit form an angle of 90 DEG, and therefore, the utility model can machine positions which a traditional electric hand drill can not machine.

Description

Elbow drill

Technical field

The utility model belongs to the metalworking technology field, is specifically related to a kind of boring direction becomes 90 degree with power output shaft electric hand drill, international Patent classificating number: B23B 45/00.

Background technology

Now the electric hand drill that can see on the market all is that the motor power output shaft is coaxial with drill bit, that is to say, the coaxial direction of the direction of motor power output shaft and drill bit is identical.In the time need holing on the object of obstacle is arranged, when such as needs electric drill being deep into machine intimate and using, and working position is owing to have a certain degree with the direction of advancing to bore, and it is convenient inadequately that above-mentioned electric hand drill just seems, or even can't use.

Summary of the invention

Goal of the invention of the present utility model is to provide a kind of direction that traditional electric drill kind of drive is changed into the motor power output shaft to become 90 ° electric hand drill with the direction of drill bit drilling.

The technical solution of the utility model is: the clutch end at motor is equipped with the support of bearing, the power output shaft of motor reaches the outside of the support of bearing, bearing is installed on the inboard and power output shaft of the support of bearing, on the power output shaft between support of bearing inboard and bearing and the motor, radiator fan is installed, is fixed with the initiative taper generating gear on the top of power output shaft; Front end at the support of bearing is equipped with gear-box, be processed with two in gear-box inside and make the dop axle dop axle bearing seat vertical with power output shaft, two dop bearings are installed in the bearing block, the dop axle that dop is installed is installed in two dop bearings, on the dop axle between two dop axle bearings, passive angular wheel is installed, this passive angular wheel and the initiative taper generating gear engagement that is fixed on the power output shaft end; Can be made into two up and down for ease of processing and assembling gear case.

Good effect of the present utility model is: can realize that the direction of motor power output shaft becomes 90 ° purpose with the direction of drill bit drilling, so just can process the position that traditional electric hand drill can not be processed.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

The goal of the invention of utility model is to realize like this, as shown in Figure 1: the clutch end at motor 1 is equipped with the support of bearing 2, the power output shaft 3 of motor 1 reaches the outside of the support of bearing 2, bearing 5 is installed on the inboard and power output shaft 3 of the support of bearing 2, on the power output shaft 3 between the support of bearing 2 inboards and bearing 5 and the motor 1, radiator fan 4 is installed, is fixed with initiative taper generating gear 7 on the top of power output shaft 3; Front end at the support of bearing 2 is equipped with gear-box 6, be processed with two in gear-box 6 inside and make the vertical dop axle bearing seat of dop axle (10) and power output shaft 3, two

dop bearings

9,11 are installed in the bearing block, the dop axle 10 that dop 12 is installed is installed in two

dop bearings

9,11, passive angular wheel 8 is installed, this passive angular wheel 8 and initiative taper generating gear 7 engagements that are fixed on power output shaft 3 ends on the dop axle 10 between two dop axle bearings; For ease of processing and assembling, gear-box 6 can be made into two up and down, and promptly the bearing block of dop bearing 9 is at last, and the bearing block of dop bearing 11 is at following sheet.

The utility model is work like this: in the time will processing the working face vertical or angled with electric hand drill power output shaft direction, opening the motor power output shaft rotates, power passes to passive angular wheel 8 by initiative taper generating gear 7, passive angular wheel 8 drives dop axle 10 and rotates, make dop 12 drillings, reach the purpose at the traditional electric hand drill of the processing position that can not process.Among Fig. 1 13 is drill bit.
