Described emery wheel 3 is externally provided with a protective hood of grinding wheel assembly, including protective hood of grinding wheel 5 and pulley 6.Specifically, described
Protective hood of grinding wheel 5 be arranged on the outside of emery wheel 3, most of profile of emery wheel 3 is all enclosed under protective hood of grinding wheel 5 to protect sand
Wheel, also ensures dust indiffusion or less diffusion；Described protective hood of grinding wheel 5 pivot is arranged at described gear train assembly
On shell, described protective hood of grinding wheel 5 is U-shaped arc profile, and the two ends of described U-shaped arc profile or wherein one end are provided with cunning
Wheel 6.
In conjunction with shown in Fig. 2, Fig. 3, when the two ends of the U-shaped arc profile in protective hood of grinding wheel 5 are provided with pulley 6, emery wheel is prevented
One projection is arranged at the top of guard shield 5, and projection is provided with an elastic component, can be spring or shell fragment, is bullet in the present embodiment
Spring 10, one end of described spring 10 is against on described protective hood of grinding wheel 5, and the other end is against on sand milling motor 2.Certainly, described tooth
Wheel transmission system and sand milling motor shell altogether, one end of described spring 10 is against on described protective hood of grinding wheel 5, and the other end also can be against
On the shell of gear train assembly.
In particular, protective hood of grinding wheel 5 is connected with sand milling motor 2 by connection sheet 9, and described connection sheet 9 is provided with 2
Individual kidney slot 8, sand milling motor 2 is provided with the circular guide pillar 7 of respective amount, and circular guide pillar 7 passes through kidney slot, makes connection sheet 9
Can move up and down along kidney slot under the restriction of guide pillar, the maximum of the length limitation of kidney slot protective hood of grinding wheel 5 movement away from
From.In the present embodiment, protective hood of grinding wheel 5 bottom is provided with 2 pulleys 6, before one, latter one, with ensure slide freely and
Steadily.Certainly, pulley 6 is arranged on and also may be used on the centre position of protective hood of grinding wheel 5.
In the present embodiment, described sanding system is carried out with respect to described vehicular platform in the presence of a lift control system
A range of elevating movement, described lift control system includes an electromagnetic adsorption system, and described electromagnetic adsorption system is
One is arranged on the electromagnet on described vehicular platform, and described electromagnet produces magnetic force in energising, and described sanding system is produced
One suction and then make described sanding system produce the displacement of relatively described vehicular platform.
When sand mill is not powered on, as shown in Fig. 2 sanding system is in liftoff highest order.Now, described circle guide pillar
The upper surface of 7 driving kidney slots 8, drives and moves on protective hood of grinding wheel 5.Now, spring 10 still can be applied to described protective hood of grinding wheel 5
The active force that plus one downward.
When sand mill energising start when, as shown in figure 3, due to sand milling motor 2, emery wheel 3, transmission driving force gear drive
System moves down in the presence of lift control system simultaneously, and circular guide pillar 7 will depart from the upper surface of kidney slot 8, now
Just compressing protective hood of grinding wheel 5 moves down spring 10.Now pulley 6 and the bottom tangent (minimum point) of emery wheel 3 are in together all the time
On one horizontal line, that is, emery wheel 3 waits sanded side to be in close contact with metallic plate all the time, and protective hood of grinding wheel 5 is also protected well
Emery wheel 3 simultaneously guarantees dust indiffusion or few diffusion.
After sand mill work a period of time, emery wheel 3 is frayed, as shown in figure 3, sanding system can be in lift control system
In the presence of continue entire lowering, spring 10 also can continuous compression contracting, and the active force of spring 10 can the bottom of driving pulley 6 be cut
Line (minimum point) is in same horizontal line with the bottom tangent (minimum point) of emery wheel 3 all the time.I.e. relative to, protective hood of grinding wheel 5
Move up with respect to the horizontal middle spindle of emery wheel 3, reach the purpose of automatic compensation.
2nd embodiment：
According to Fig. 4, when one end of the U-shaped arc profile in protective hood of grinding wheel 5 is provided with pulley 6, described emery wheel is prevented
Guard shield 5 pivot is arranged on described sand milling motor 2 or the shell of gear train assembly, connects for rotating between the two, for example may be used
(not shown) is connected with the guide pillar on sand milling motor 2 with the kidney slot arranging Curved on protective hood of grinding wheel 5.
When sand mill energising starts, sand milling motor 2, protective hood of grinding wheel assembly and emery wheel integrally move down, and emery wheel is prevented
The pulley 6 of guard shield 5 bottom is contacted with emery wheel 3 simultaneously treats sanded side.After sand mill work a period of time, emery wheel 3 is frayed,
Sanding system can continue entire lowering in the presence of lift control system, and treats that sanded side can apply one to described pulley 6
Individual reaction force, this reaction force driving protective hood of grinding wheel 5 rotates along the curved shape of kidney slot with respect to emery wheel 3, reaches
Automatically the purpose compensating.Now pulley 6 and the bottom tangent (minimum point) of emery wheel 3 are in same horizontal line, i.e. emery wheel 3
All the time wait sanded side to be in close contact with metallic plate, and protective hood of grinding wheel 5 is also protected emery wheel well and guaranteed that dust does not expand
Dissipate or few diffusion.
The automatic sand mill of self adaptation realized by above technical approach can be adjusted to emery wheel after abrasion of grinding wheel,
So that the sand milling depth is consistent, reach the purpose of automatic compensation.
Carried in the present invention upper and lower for relative concept, under being, be upper away from ground, in the present invention close to ground
The scheme that technical characteristic is carried out obtained by simple change or customary means displacement is included within the scope of protection of the invention.
