And pivoting part 9, mounting plate 6, horizontal slide unit 7, longitudinal slide unit 8 and pivoting part 9 are installed in the welding stand 5
On, wherein horizontal slide unit 7 is slidably connected with welding stand 5, and the mounting plate 6 is for installing grinding device and being fixed on welding
In rack 5, pivoting part 9 is for installing workpiece 18 to be polished.
The longitudinal slide unit 8 be slidably mounted in the horizontal slide unit 7 and can transversely slide unit 7 length direction from
By sliding, the supporting plate 13 also normal thereto in longitudinal slide unit 8, slidably 8 length direction of slide unit is sliding along longitudinal direction for the supporting plate 13
It is dynamic, and the free end upper surface of the stretching longitudinal slide unit 8 of supporting plate 13 is equipped with the pivoting part 9, and supporting plate 13 is being slided
When pivoting part 9 on workpiece 18 can be contacted with the milling tools of the grinding device on the mounting plate 6.
The grinding device includes polishing rack 17, upper polishing component, lower polishing component, and the lower polishing component includes bearing
Seat-box 1 and the polishing axis 2 being mounted in bearing seat-box 1, the output end of axis 2 of polishing towards its end direction be successively fixedly installed with from
Moving gear 3, the second belt wheel 10, upper polishing component includes the polishing motor 11 for being fixedly mounted on 1 upper surface of bearing seat-box, institute
It states and is successively fixed with first pulley 14, driving gear 16 towards its end on the main shaft 12 of polishing motor 11, be fixedly installed in described
The polishing rack 17 on bearing seat-box 1 is in inverted L-type, and the cantilever beam of polishing rack 17 is sequentially installed with two by its free end
Two driven pulleys cooperated respectively with the first pulley 14, the second belt wheel 10, so that two polishing belts 15 are installed respectively
In corresponding belt wheel group, and the driving gear 16 and the engaged transmission of driven gear 3 and make two polishing belts 15 fortune
It moves contrary.
When using this numerical control sander, the transverse direction that is arranged on welding stand 5, longitudinal slide unit 8 realize clamping workpiece 18
Pivoting part 9 it is mobile, and longitudinal slide unit 8 is slidably mounted in horizontal slide unit 7, can transversely slide unit 7 be slided, so that longitudinal
Slide unit 8 laterally move apart from further expansion, and planker is to be slidably mounted in longitudinal slide unit 8 and can slide unit along longitudinal direction
The sliding of 8 length directions, vertically moves pivoting part 9 neatly, so that the pivoting part 9 of clamping workpiece 18 has
There is a biggish moving range, meanwhile, for the flexibility for promoting grinding effect and using, specially design special polishing dress
It sets, the numerically controlled processing equipments such as the grinding device and general grinding machine are different, are the belt polishings used, are beaten using friction belt
18 surface of grinder part can be polished to the place that many rigid grinding wheels cannot be polished to, and will not so that polishing is more abundant
Occur forcing polishing, because there is polishing belt 15 itself flexibility can adaptively be covered on some special surfaces of workpiece 18,
Realize the polishing of better and safer；Also, the grinding device uses two-way polishing, and grinding effect is more preferable, is not easy clamping stagnation,
For the more coarse workpiece 18 in surface, the grinding efficiency of two-way polishing is higher, is aided with the flexible speciality of belt, can
More ideally to polish some abnormal workpieces 18, it can be seen that, the numerical control sander structure is simple, grinding efficiency is high, effect
Fruit is good, is particularly suitable for slightly soft 18 surface of the special-shaped workpiece polishing of some hardness.
Further, the diameter ratio and the driving gear 16 of the first pulley 14 and the second belt wheel 10 with it is driven
The transmission effect of the be superimposed generation of transmission ratio between gear 3 is faster than 15 movement velocity of polishing belt of lower polishing component
The movement velocity of the polishing belt 15 of polishing component.This design is primarily due to 15 elder generation of polishing belt and the workpiece of lower polishing component
18 contacts are once polished, and required polishing speed is when slightly faster, the preferably excellent effect polished of matching Double direction differential,
It fully ensures that polishing quality and grinding efficiency, while clamping stagnation can be better protected from.
Further, the first pulley 14 and the second belt wheel 10 is in the same size, and 16 number of teeth of the driving gear is more
In the number of teeth of driven gear 3, it is faster than with more simply more directly effectively realizing 15 movement velocity of polishing belt of lower polishing component
The function of the movement speed of the polishing belt 15 of upper polishing component.
Further, the horizontal slide unit 7 is driven by drag chain 20, directly to buy drag chain 20 from market, is simplified
Production.
Further, the bottom end of four feet of the welding stand 5 is equipped with lower margin 4, it is ensured that solid and reliable.
Further, overload protection arrangement, the overload protection arrangement are equipped between second belt wheel 10 and polishing axis 2
So that the second belt wheel 10 skids under the predetermined frictional force that polishing belt 15 transmits, it is stuck to avoid polishing component instantly
When, the normal work of polishing component is influenced, and entire polishing function will not be caused to stop because lower polishing component is stuck
Only, it because frictional force is more more easily stuck greatly when the polishing of lower polishing component, cannot be influenced because of lower polishing component stuck
Upper the stuck of component of polishing, so that at least one polishing component works normally, structure design is very ingenious, structure letter
It is single, but greatly improve the service performance of numerical control sander entirety.
Further, as shown in figure 4, the overload protection arrangement includes friction of two pairs of arranged for interval on polishing axis 2
Component, the friction component include the adjusting nut 19 being screwed on polishing axis 2, cover the holddown spring 21 on polishing axis 2 and rub
Scrubbing pad piece 22, be equipped with second belt wheel 10 between two friction shims 22 of two friction components and two adjusting nuts 19 tighten after make
The both ends of the surface close proximity of two friction shims 22 and the second belt wheel 10 is obtained, so that the second belt wheel 10 passes through the folder of two friction shims 22
Tight effect is fixed on polishing axis 2, when belt 15 of polishing occurs relative motion clamping stagnation and generates huge frictional force with workpiece 18,
Second belt wheel 10 starts to skid relative to friction shim 22, plays overload protective function.This kind of structure makes overload protection arrangement
Manufacturing cost is cheap, simple and reliable for structure.
The above embodiments are only illustrative of the principle and efficacy of the utility model, and not for limitation, this is practical new
Type.Any person skilled in the art can all carry out above-described embodiment under the spirit and scope without prejudice to the utility model
