Description
Technical field
The utility model belongs to mechanical fitting technical field, more particularly, to a kind of drill holder.
Background technology
Decelerator is that a kind of gear drive, worm-drive, gear worm transmission by being enclosed in stiff case is formed
Individual components, the speed reduction gearing being commonly used between driving link and working machine.In prime mover and working machine or executing agency
Between play a part of match rotating speed and transmit torque, the connection of reductor and motor is by motor output shaft and reductor worm screw
Cooperation realize.
The output shaft of single motor can only be adapted to a kind of some phases of the decelerator, the decelerator of different size etc. of worm screw specification
Equipment is answered to need to be coordinated with different motors, the scope of application is small, and often changes a kind of specification, all needs to open up a variety of moulds
Tool, causes greatly improving for production cost.
Utility model content
In place of the purpose of this utility model is the deficiencies in the prior art to be solved, and one kind is provided can quickly to change motor defeated
Go out the drill holder of shaft diameter, it is applied widely.
The purpose of this utility model is that solved by following technical proposal：
A kind of drill holder, it is characterised in that：Including annulus cylindricality drill holder body, drill holder body left side wall offers use
In the first dowel hole with motor input axis connection, drill holder body right side wall offer for be connected with worm screw output end the
Two dowel holes；
First dowel hole is through hole.
Alternatively, the second dowel hole described in the utility model is through hole.
Further, the width of the first dowel hole described in the utility model is less than the width of the second dowel hole, the first keyway
The height in hole is less than the height of the second dowel hole.
Alternatively, the second dowel hole described in the utility model is blind hole.
Further, the width of the first dowel hole described in the utility model is less than the width of the second dowel hole, the first keyway
The height in hole is slightly less than the height of the second dowel hole.
Preferably, the material of drill holder body described in the utility model is 45# steel.
Compared to the prior art the utility model has the characteristics that and beneficial effect：
Drill holder can effectively change the external diameter of motor output shaft, to coordinate the decelerator of different size, assemble simple fast
Speed, the scope of application of motor is improved, reduce production cost, drill holder is equally applicable to other and uses identical connection side simultaneously
The equipment of formula, strong adaptability.

Embodiment
The utility model is described in further details below in conjunction with accompanying drawing.
As Figure 1-4, embodiment 1：
A kind of drill holder, including annulus cylindricality drill holder body 1, the left side wall of drill holder body 1, which offers, to be used for and motor
The first dowel hole 2 of axis connection is exported, the right side wall of drill holder body 1 offers the second keyway for being connected with worm screw input
Hole 3.
First dowel hole 2 is through hole, and the second dowel hole 3 is through hole, and the width of the first dowel hole 2 is less than the second keyway
The width in hole 3, the height of the first dowel hole 2 are less than the height of the second dowel hole 3.
At work, first by drill holder body 1 set be set to outside motor output shaft, corresponding installation key is pressed into the first keyway
Hole 2 and motor output shaft simultaneously fix it, then the installation key coordinated with it is put into the second dowel hole 2, finally provided with installation
It is external that the worm screw of groove along installation key set is set to drill holder sheet, completes assembling.Because the diameter of motor output shaft is smaller, therefore use
In the first dowel hole 2 coordinated with motor output shaft in the case where can ensure that its function, selection of small size as far as possible.And worm screw
Be relatively large in diameter, in order to ensure transmission, the size of the second dowel hole 3 is greater than the first dowel hole 2.
The material selection 45# steel of drill holder body 1, there is good comprehensive mechanical performance.
As viewed in figures 5-8, embodiment 2：A kind of drill holder, including annulus cylindricality drill holder body 1, drill holder body 1 are left
Side wall is offered for the first dowel hole 2 with motor axis connection, and the right side wall of drill holder body 1 is offered for being connected with worm screw
The second dowel hole 3.
First dowel hole 2 is through hole, and the second dowel hole 4 is blind hole, and the width of the first dowel hole 2 is less than the second keyway
The width in hole 3, the height of the first dowel hole 2 are slightly less than the height of the second dowel hole 3.
At work, first by drill holder body 1 set be set to outside motor output shaft, corresponding installation key is pressed into the first keyway
Hole 2 and motor output shaft simultaneously fix it, then the installation key coordinated with it is put into the second dowel hole 2, finally provided with installation
It is external that the worm screw of groove along installation key set is set to drill holder sheet, completes assembling.Because the diameter of motor output shaft is smaller, therefore use
In the first dowel hole 2 coordinated with motor output shaft in the case where can ensure that its function, selection of small size as far as possible.And worm screw
Be relatively large in diameter, in order to ensure transmission, the size of the second dowel hole 3 is greater than the first dowel hole 2.
The material selection 45# steel of drill holder body 1, there is good comprehensive mechanical performance.
Drill holder body 1 in the utility model can effectively change the external diameter of motor output shaft, to coordinate different size
Decelerator, assembling it is simple and quick, improve the scope of application of motor, reduce production cost.
Specific embodiment described herein is only to the utility model spirit explanation for example.The utility model institute
Category those skilled in the art can make various modifications or supplement to described specific embodiment or using similar
Mode substitute, but without departing from spirit of the present utility model or surmount scope defined in appended claims.
