Technical field
It the utility model is related to a kind of polishing vacuum absorption device for strengthening adsorption.
Background technology
Because that compared to traditional positioning tool, without assembling and dissembling process, operation can be simplified and improve efficiency, it is known that enterprise is to workpiece flowing water
The workpiece on constant transmissions belt is all adsorbed using vacuum absorption device when changing polishing grinding operation.
Its composition of vacuum absorption device common at present mainly includes vacuum cavity, absorption cover plate, pipeline and vacuumized to set
It is standby.Vacuum cavity is enclosed and is spliced by bottom plate and four cycle side plates, and absorption cover plate is fixed on vacuum cavity top, adsorbs on cover plate
Adsorption hole is densely covered with, and adsorbs generally also to correspond on the transmission belt above cover plate and is densely covered with perforate.On the side plate of vacuum cavity
Provided with air entry, it is connected by pipeline with vaccum-pumping equipment.The air in vacuum cavity is taken out in use, starting vaccum-pumping equipment
Sky forms negative pressure so as to which absorption of workpieces is fixed on the transmission belt above absorption cover plate.
But known above-mentioned adsorbent equipment is be exposed during long-term use the problem of：
Vacuum cavity is often inadequate for the absorption affinity of workpiece, and adsorption is not high, traces it to its cause and is when belt operates
When making the adsorption hole in perforate thereon and absorption cover plate identical, the adsorption hole that reality works to absorption workpiece is seldom, and remaining
Adsorption hole pass through perforate and ventilated with extraneous（Gas leakage）On the contrary reduce the negative pressure performance in vacuum cavity, influence adsorption.
In order to solve the above problems, current corrective measure is generally all to change powerful vaccum-pumping equipment to inhale to strengthen
Power, but actual effect is limited, and enterprise's production cost is added on the contrary.
The content of the invention
The purpose of the utility model is：A kind of polishing vacuum absorption device for strengthening adsorption is provided, it is without increase
Vaccum-pumping equipment power just can obtain more excellent adsorption.
The technical solution of the utility model is：A kind of polishing vacuum absorption device for strengthening adsorption, including negative pressure
Cavity, the absorption cover plate for being fixed on vacuum cavity top and above absorption cover plate for transmitting the transmission belt of workpiece, institute
To state and be provided with some row adsorption holes along the transmission belt direction of motion on absorption cover plate, the adsorption hole uniform intervals in each row are distributed, and
Then correspond to each row adsorption hole below on transmission belt and be provided with some row perforates, the perforate in each row also uniformly between
Every distribution, the vacuum cavity is connected provided with air entry by pipeline with vaccum-pumping equipment；It is characterized in that the adsorption cover

Meet following condition：2l+b>L>L, while 2l+b>a>B, and a, L, b, l are all higher than 0, so when transmission belt operates, all the time
Only part open and the adsorption hole break-through on dislocation adsorption zone.
Further, a=L described in the utility model, and b+l=L, when transmission belt operates, only one is half-open all the time
Hole and the adsorption hole break-through on dislocation adsorption zone.
Preferably, b=l described in the utility model.
Cover plate is adsorbed described in the utility model and is provided with common adsorption zone, the length of the commonly adsorption hole in adsorption zone
Degree is equal to the length of the perforate on transmission belt, while often the spacing of capable two neighboring adsorption hole is equal to transmission in common adsorption zone
On belt often go two neighboring perforate length.
Further, intermediate distribution of the common adsorption zone described in the utility model along absorption cover plate, and the adsorption zone that misplaces
For two, the both sides of the common adsorption zone are distributed in.
Further, the adsorption hole of dislocation adsorption zone described in the utility model is slotted hole, and when on transmission belt
When perforate is overlapping with the adsorption hole on dislocation adsorption zone, orthographic projection of the adsorption hole on transmission belt on the dislocation adsorption zone
Contour area covers the contour area of the perforate.The utility model of shape in to(for) perforate does not limit actually, only needs
Its contour area is less than the absorption hole area to misplace on adsorption zone just, it is ensured that perforate can obtain the gettering efficiency of maximum（I.e.
Perforate gross area air-breathing utilizes）.
Further, when the perforate on transmission belt is overlapping with the adsorption hole on common adsorption zone in the utility model
When, the orthographic projection contour area of the commonly adsorption hole on adsorption zone on transmission belt covers the contour area of the perforate
Or coincide with.Similarly for the adsorption hole size on common adsorption zone, we are also not specifically limited, and only need to ensure perforate energy
It is enough to obtain maximum gettering efficiency（I.e. perforate gross area air-breathing utilizes）.
The utility model has the advantages that：
1. the utility model is corresponded on adjustment transmission belt by setting special dislocation adsorption zone in absorption cover plate
Perforate length and spacing distribution, it is ensured that when in transmission belt motion process, it only has part open and absorption cover plate dislocation all the time
Adsorption hole break-through on adsorption zone, rather than whole perforates all correspond to air-breathing as usual, so do carrying to a certain extent
The high negative pressure performance of vacuum cavity, effectively increases the suction for workpiece, enhances the adsorption of device.
2. the utility model need to be only modified to transmission belt and absorption cover plate, it is to be changed without and raising is taken out very
The lifting of the adsorption obtained on the premise of null device power, greatly save the improving cost of production equipment.
3. common adsorption zone further is set in transmission belt center in the utility model, and both sides set dislocation absorption
Area, because center often contacts intensive region with workpiece, it is main adsorption zone, so does actually significantly more efficient enhance
Main adsorption zone substantially increases the absorption steadiness for workpiece, is advantageous to carrying for polishing quality for the adsorption of workpiece
It is high.
