Description
Technical field
The present invention relates to engraving tool technical field, grinding machine is hung more particularly, to one kind.
Background technology
When metal and non-metallic object are compared fine engraving, it will necessarily use and hang grinding machine.Common hangs mill
Machine includes lower house and upper shell, and the top of lower house is provided with 2 connecting poles protruding upward, and connecting pole is provided with screw, on
Housing is realized by the screw and lower house that are screwed onto in screw to coincide.Wherein, set in the space of upper shell and lower house formation
There are stator and rotor, the rotary shaft of rotor extend out to the outside of the upper shell, and the upper end of the rotary shaft is connected by power flexible axle
It is connected to tool heads.Certainly, tool heads can be changed easily, and the rotary shaft of the rotor is provided with cooling fan.Meanwhile,
The stator is connected to power supply by a footswitch.
The foregoing defect for hanging grinding machine is：
1st, footswitch speed governing is not accurate enough.Reason is, footswitch and hang grinding machine for split-type structural, it is necessary to
Lead realizes switch and hangs the connection of electrical equipment inside grinding machine, so that structure is not reasonable.In other words, it is necessary to which there is a space on ground
Footswitch is placed, and live wire is connected, and potential safety hazard is also easy to produce after abrasion.Meanwhile, footswitch needs to use foot control
System, user, which must be seated, to be operated well, stand or couchant just bad operate.In addition, control of the foot to switch
System by experience and is felt to carry out mostly, and precision hardly possible support is held.
2nd, the space that cooling fan can take is smaller, and main cause is the space that 2 connecting poles occupy cooling fan,
Final to make that the diameter of cooling fan is smaller, radiating effect is poor.
The content of the invention
For above-mentioned prior art exist deficiency, hang grinding machine it is an object of the invention to provide one kind, it have speed governing compared with
For it is accurate and timely the characteristics of.Further, it also has the characteristics of cooling effect is preferable.
To achieve these goals, the technical solution adopted in the present invention is：
Grinding machine, including housing are hung, the enclosure interior is provided with stator and rotor, and the rotor has rotary shaft, in the rotary shaft
Provided with cooling blade, meanwhile, the rotary shaft connects dynamic flexible axle, and the power flexible axle other end is connected with tool heads, and, should
Stator is connected to power supply by switch, and the switch includes the speed-regulating switch and master switch being cascaded, the speed-regulating switch and
Master switch is respectively positioned on the housing.
The speed-regulating switch and master switch are located on the same side of the housing.
The speed-regulating switch is knob speed-regulating switch, and the adjusting knob of the speed-regulating switch is marked with speed governing digital.
The housing is the tubular of upper opening, and integrally formed provided with least three opening court on the side wall of the housing
On screw, there is a cover plate to be fixed by screws on the upper opening of the housing, screw is corresponding two-by-two to be screwed onto in screw,
Meanwhile, the middle part of the cover plate is provided with positioning hole, and the rotary shaft passes through the positioning hole, the cooling in the top of the vertical and rotary shaft
Blade is located in the housing and positioned at the lower section of the cover plate.
The external diameter of the cooling blade is 1.5-2.5 times of the root diameter.
The invention has the advantages that compared with the prior art,：
1st, speed governing is more accurate and timely.Using knob speed-regulating switch, speed-regulating switch and master switch are respectively positioned on housing,
It is easy to user to be operated, and speed governing digital is easy to user directly perceived and accurately grasps speed governing effect, more accurately.
2nd, relatively low is required to operator.Low to operating environment requirements without the space of foot, operator can stand work
Industry.
3rd, cooling effect is preferable.By using the housing of integral type, the space for enabling cooling fan to take is larger, so that
Cooling fan is relatively large in diameter, and radiating effect is preferable.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples：
Fig. 1 is the perspective exploded view for hanging grinding machine of embodiments of the invention；
Fig. 2 is the top view (being exaggerated relative to Fig. 1) of the housing of the present invention；
Fig. 3 is the schematic perspective view (being exaggerated relative to Fig. 1) of the speed-regulating switch of the present invention.
Embodiment
Embodiment, as shown in Fig. 1 to Fig. 3：Hang grinding machine, including housing 10.The inside of housing 10 is provided with stator 21 and rotor
22.The rotor 22 has rotary shaft 221, and the rotary shaft 221 is provided with cooling blade 222.Meanwhile, the rotary shaft 221 is connected with
Power flexible axle, the power flexible axle other end is connected with tool heads.That is, after the rotor 22 rotation, by the power flexible axle by moment of torsion
Tool heads are transferred to, can then carry out the operation such as carving.And, the stator 21 is connected to power supply by switch.That is, switch is closed
After conjunction, the stator 21 is powered, and the rotor 22 rotates.
Further say：
The switch includes the speed-regulating switch 31 and master switch 32 being cascaded, the speed-regulating switch 31 and the equal position of master switch 32
In on the housing 10.In such manner, it is possible to conveniently controlling switch, accomplish in time and precise manipulation.Wherein, the speed-regulating switch 31
Speed governing digital 311 is marked with for the adjusting knob of knob speed-regulating switch, and the speed-regulating switch 31.Speed governing digital 311 can be
Numeral is waited in " 1 ", " 2 ", " 3 " ..., in order to which user being capable of accurately speed governing.In addition, the master switch 32 is preferably with pressing
Formula is switched.
Optimization：
The speed-regulating switch 31 and master switch 32 are located on the same side of the housing 10.Such as, when the housing 10 is in circle
During cylindricality, the phase difference of the speed-regulating switch 31 and the position of master switch 32 is no more than 90 °；Put down when the side of the housing 10 has
When face or the housing 10 are square, the speed-regulating switch 31 and master switch 32 are located in the approximately the same plane of the avris of housing 10.
So, the speed-regulating switch 31 and master switch 32 can make operation more convenient simultaneously against operator.
The housing 10 is the tubular of upper opening, and is integrally formed on the side wall of the housing 10 by modes such as integrated injection moldings
Provided with the opening up screw 11 of at least three.In the present embodiment, screw 11 is 4.There is a cover plate 12 solid by screw 121
On the upper opening for being scheduled on the housing 10, screw 121 is corresponding two-by-two to be screwed onto in screw 11.Meanwhile, the middle part of the cover plate 12
Provided with positioning hole 122, the rotary shaft 221 passes through the positioning hole 122 in the top of the vertical and rotary shaft 221.Obviously, the rotation
The bottom of axle 221 can be positioned at the intracavity bottom of the housing 10 by bearing.The cooling blade 222 is located in the housing 10
And positioned at the lower section of the cover plate 12.So, by using the housing 10 of integral type, provide and more fill for the cooling blade 222
Abundant space, is easy to the sufficiently large of the diameter preparation of the cooling blade 222.In the present embodiment, the external diameter of the cooling blade 222
For 1.5-2.5 times of the diameter of rotor 22.Such as, the external diameter of the cooling blade 222 is 1.5,2 or the 2.5 of the diameter of rotor 22
Times.
The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the scope of the invention, it is every to utilize
Equivalent structure or equivalent flow conversion that description of the invention and accompanying drawing content are made, or directly or indirectly it is used in other correlations
Technical field, be included within the scope of the present invention.
