Detailed description of the invention
Fig. 1 is the structural schematic diagram of the mini small electric drill in the present invention.
Fig. 2 is the enlarged diagram in the portion A in Fig. 1.
Fig. 3 is the enlarged diagram of the drill point of mini small electric drill, drill bit fixed cell and electric-motor drive unit in the present invention.
Specific embodiment
To make those skilled in the art that the purposes, technical schemes and advantages of invention be more clearly understood, below
Invention is further elaborated in conjunction with the accompanying drawings and embodiments.
A kind of mini small electric drill, including drill point 5, drill bit fixed cell 1, electric-motor drive unit 2 and power supply unit 3；It is described
5 fixed cell 1 of drill point includes shell 11, and guide sleeve 12 is arranged in the shell 11；The electric-motor drive unit 2 includes motor
21；Described 5 one end of drill point passes through the guide sleeve 12 and is connected by flexible shaft 22 with the motor 23.In some preferred implementations
In example, the mini small electric drill further includes charhing unit 4.
Referring to Figure 2 together, it is preferable that bearing 13 is set between the shell 11 and guide sleeve 12.It is preferred that described
Bearing 13 includes spaced first bearing 131 and second bearing 132, further increases stability and consistency.Preferably,
The first bearing 131 and second bearing 132 pass through the isolation connection of retaining ring 14.12 interference of guide sleeve is embedded in described first
In bearing 131 and second bearing 132.In some preferred embodiments, the second bearing 132 is far from first bearing 131 1
Side setting holds out against ring 15.In certain embodiments, the first bearing 131 and second bearing 132 are ball bearing.
It is appreciated that assembling process is, drill point 5 is packed into guide sleeve 12, is fitted close with guide sleeve 12, guarantees drill point 5
With the consistency of guide sleeve 12 at work；12 interference of guide sleeve is embedded into first bearing 131 and second bearing 132, two rollings
Pearl bearing passes through the isolation connection of retaining ring 14；First bearing 131 and second bearing 132 are packed into shell 11, and by holding out against ring 15
Assemble it integrally with shell 11.
Guide sleeve 12 is hidden in shell 11, and at work, only 5 high speed rotation of drill point, reduces exposed rotary body, subtract
Few injury to operator；Drill bit fixed cell 1 selects high-precision bearing, and drill point 5 is fixed by duplex bearing, 5 quilt of drill point
Bearing includes enough length, ensure that the running accuracy of drill point 5, meets borehole accuracy needs.
Also referring to Fig. 3, drill point 5 is connected on motor 21 by flexible shaft 22, and flexible shaft 22 transmits motor 21 and transmits
Come rotation, torque, and by itself Light deformation offset motor 21 and drill point 5 bias, ensure that electric drill export drilling
Precision.
Preferably, the flexible shaft 22 is in hollow tubular, and one end is socketed the drill point 5, and the other end is socketed the motor 21
Motor shaft 211.Flexible shaft 22 provides 5 installation fixing position of drill point, provides enclasping force when work, the fast plug of drill point is supported to pacify
Dress mode.Flexible shaft 22 is made such as the rubber tube that fluorubber material is done by natural resiliency using with the pipe that elastic material is made into
With wrapping motor shaft 211, drill point 5.
Drill point 5 is inserted into flexible shaft 22, and 22 one end of flexible shaft connects motor 21；Push switch button 25, power supply unit 3 are given
Motor 21 is powered, 5 high speed rotation of drill point that the work of motor 21 drives flexible shaft 22 and is fixed on flexible shaft 22.
Preferably, the electric-motor drive unit 2 further includes shell 23, and the motor 21 is mounted in the shell 23.Into
One step, the motor 21 are fixed on the shell 23 by mounting base 24.The vibration in the work of motor 21 is reduced, is reduced
Noise transmission.
Mini small electric drill provided by the present invention realizes that the duplex bearing implication of drill bit is fixed, and is transmitted by flexible shaft
Torque, the drill bit mounting means that plugs fastly of support avoid the throwing of injury to operator, clast to meet application environment
