Abstract

The invention discloses a steering gear for changing drill bit directions of an electric drill. The electric drill is one of the most commonly used tools during mechanical operation and is convenient to use and flexible in operation, however, complex environments or workpieces limited in size are frequently encountered during operation, and the electric drill cannot extend into the workpieces for operation due to the fact that the length of an drill bit is beyond the size. In order to solve the problem, an L-shaped tube and a T-shaped tube are utilized to make a coupling base, two pairs of 45-degree bevel gears are arranged in the coupling base to form a serially-connected coupling, and drilling directions of an existing electric drill are changed by the aid of driving of drive shafts. The drill bit can be conveniently mounted and dismounted on the electric drill, the drill bit and can be replaced directly, the directions of the drill bit of the electric drill can be changed optionally in 360 degrees without changing the existing electric drill to enable the electrical drill to be operated inside the complex workpieces limited in size or in the complex environments, and accordingly operation limit of conventional electric drills is overcome.

Description

A kind of steering gear that changes the drill bit direction

Technical field

What the present invention relates to is a kind of steering gear that changes the drill bit direction, belongs to the motor machine technical field.

Background technology

Drill bit is an instrument the most frequently used in the mechanically actuated, has the characteristics of flexible operation easy to use, can be applied in the diversified environment, all can use in nearly all construction, in mechanically actuated, has brought into play enormous function.But meet the perhaps workpiece of size-constrained system of some complex environments through regular meeting in the operation, existing electric drill is because drill bit length is long, and can't be placed into wherein perhaps can't be with vertical angle boring.Therefore, seeking a kind ofly can change bore angle and drill bit length, can make the device that workpiece that electric drill faces complex environment or size-constrained system also can normal running, is highly significant.

Summary of the invention

The object of the invention just provides a kind of steering gear that changes the drill bit direction; The axle connected device that this steering gear mainly utilizes two groups of gears to form reaches drill bit length and the bore angle that changes electric drill; The purpose that electric drill after this steering gear can be operated complex part or narrow environment make to be installed; And this steering gear can make things convenient for dismounting freely, has overcome the shortcoming of operating inconvenience even can't operate when traditional electrical is drilled in the face of narrow environment or complex part.

The foregoing invention purpose is achieved; It is because adopted following technical scheme: a kind of steering gear that changes the drill bit direction; Comprise a L type pipe and a T type pipe that is connected with L type pipe, an end of L type pipe links to each other with input adapter, and the other end is fixed with the jointing of a band disk; Living between one end of the horizontal body of T type pipe and the jointing is connected, and can do 360 ° and turn to arbitrarily; The other end of the horizontal body of T type pipe is fixed with the anchor tip of a band disk, and corresponding fixing hole is arranged on the clutch disk of jointing and the fixed disc of anchor tip, passes through bolt between the fixing hole; Be fixed with the input bearing in the input adapter, be fixed with input shaft on the input bearing, input shaft stretches into L type Guan Yiduan and is fixed with the input bevel gear; Be fixed with connection bearing in the jointing, be fixed with the connection power transmission shaft on the connection bearing, the end that the connection power transmission shaft gos deep into L type pipe is fixed with the connection bevel gear, imports bevel gear and is connected the bevel gear engagement; The end that the connection power transmission shaft gos deep into the horizontal body of T type pipe is fixed with the transmission bevel gear; T type pipe vertically end links to each other with out splice going splice; Be fixed with the output bearing in the out splice going splice; Be fixed with take-off (propeller) shaft on the output bearing, take-off (propeller) shaft is stretched into by vertical end of T type pipe, and an end that stretches into T type pipe is fixed with the output bevel gear; Transmission bevel gear and the engagement of output bevel gear, the take-off (propeller) shaft other end is fixed with an electric drill drill point.

Take the present invention of above-mentioned measure; The T type pipe that utilizes L type pipe and link to each other with L type pipe is as axle connected device pedestal; Two pairs of 45 ° of bevel gears are set have constituted two axle connected devices; Two-stage axle connected device is together in series and changes twice rotation direction, drives drill point through the power transmission shaft that links to each other with bevel gear simultaneously, has changed the final boring direction of original electric drill.Thereby the present invention has 360 ° of rotations of drill bit do that can make electric drill regulates boring direction arbitrarily; Need not change electric drill, conveniently detachable on electric drill, drill bit can directly be changed; The characteristics that can make electric drill under the inner perhaps complex environment of the complex part of size-constrained system, hole or polish; Expanded the range of application of electric drill, saved man-hour, made electric drill give play to bigger effect.

For specifying the present invention,, the present invention is made further detailed description below in conjunction with the accompanying drawing and the specific embodiment.
