Specific embodiment
The present invention will be further described in detail below with reference to the embodiments, following embodiment be explanation of the invention and
The invention is not limited to following embodiments.
As described in Figure 1, the grinding hydraulic regulating system for grind spectacle lens of the present embodiment, including water pump 90, grinding liquid case
10, vertical tube 11, grinding mechanism 20, eyeglass to be ground 50, filter 60 and reservoir 93 pass through inverted U-shaped the at the top of water pump 90
It is connected at the top of two conduits 92 and grinding liquid case 10,10 top of grinding liquid case also has the switch 13 for being placed in lapping liquid, grinding
The bottom of liquid case 10 is connected to by vertical tube 11 with grinding mechanism 20, is had inlet opening 12 on the side wall of vertical tube 11, is ground mechanism 20
Filter 60 is arranged in lower section, and 60 surface of filter has sieve pore, and liquid can be flowed into filter 60 by sieve pore.Filter 60
Eyeglass 50 to be filtered is placed in top, and eyeglass 50 to be filtered is corresponding with the grinding position of mechanism 20.Filter 60 divides for coarse grain mistake
Filter 61, particulate filter 62, molecular filter 63 are simultaneously successively from top to bottom connected to, in coarse grain filter 61, particulate filter
62, the inside of molecular filter 63 all has removable filter net, dismountable and replaced when grinding waste material and saving bit by bit more
Strainer.It is connected to by third connecting tube 23 with reservoir 93 in the bottom of molecular filter 63, passes through first at the top of reservoir 93
Conduit 91 is connected to 90 bottom of water pump.
When the grinding hydraulic regulating system work for grind spectacle lens of the present embodiment, the switch at 10 top of liquid case will be first ground
13 open, by lapping liquid by the way that in the merging grinding liquid case 10 of switch 13, turning off the switch 13 makes grinding liquid case 10 keep air-tight state.
Lapping liquid flows into grinding mechanism 20 by vertical tube 11.After the grinding of grind spectacle lens 50 is treated in completion, lapping liquid and grinding clast one
And flow into filter 60, by the filtering of coarse grain filter 61, particulate filter 62, molecular filter 63, lapping liquid passes through
Third connecting tube 23, when the lapping liquid in grinding liquid case 10 is inadequate, opens water pump 90 into reservoir 93, will be in reservoir 93
Lapping liquid from the first conduit 91, the second conduit 92 return grinding liquid case 10, when grind liquid case 10 in lapping liquid it is enough when, close
Water pump 90 is closed, to achieve the purpose that economize on resources.
In conjunction with Fig. 2, grinding mechanism 20 includes water level chamber 30, water storage cavity 33,40 and of adjusting cavity being sequentially communicated from top to bottom
Grinding head 51.A motion bar 31 is connected in the one side wall of water level chamber 30, one end of motion bar 31 and water level chamber 30 are pivotally connected, are living
31 other end of lever connects floating ball 32, and 30 bottom of water level chamber is equipped with the first connecting tube 21, and water level chamber 20 passes through the first connecting tube 21
It is connected to water storage cavity 33, there is through-hole at the top of the first connecting tube 21, there is the plug cooperated with through-hole, water level chamber on motion bar 31
Lapping liquid in 30 flows into water storage cavity 33 from the through-hole of the first connecting tube 21, and 33 upper surface of water storage cavity has elasticity.Work as water storage cavity
When water in 33 is reduced, 33 upper surface of water storage cavity makes the water level decreasing in water level chamber 30, to make 32 descent tape of floating ball to recessed
Dynamic motion bar 31 is rotated relative to water level chamber 30, separates the plug on motion bar 31 with the through-hole in the first connecting tube 21, with
This to reach the air pressure balance in water level chamber, forces the lapping liquid in grinding liquid case to flow into water level chamber 30 by vertical tube 11 simultaneously
In.When lapping liquid, which enters water level chamber 30, increase water level, floating ball 32 floats and drives motion bar 31 relative to 30 turns of water level chamber
It is dynamic, cooperate the plug on motion bar 31 and the through-hole of the first connecting tube 21, plug, which blocks through-hole, makes lapping liquid be no longer flow into storage
Water cavity 33.
Water storage cavity 33 is connected to by the second connecting tube 22 with adjusting cavity 40, adjusting cavity 40 be it is movable and with the second connecting tube
22 relative motions are fixedly connected with telescopic rod 41 on bottom in adjusting cavity 40, and telescopic rod 41 upwardly extends, and 41 diameter of telescopic rod is greater than the
The diameter of two connecting tubes 22, the upward diameter in the top of telescopic rod 41 gradually become smaller to form cone, the cone top of telescopic rod 31
Portion protrudes into 22 bottom of the second connecting tube.41 top two sides of telescopic rod connect one end of adjusting rod 42, adjusting rod 42 by connecting rod 43
The other end pass through adjusting cavity 40 side wall extend outwardly and end formed handle 44.40 bottom of adjusting cavity connects grinding head
51, there is the drainage hole 45 of connection 40 bottom wall of adjusting cavity and grinding head 51 on 40 bottom wall of adjusting cavity.
When the grinding hydraulic regulating system work for grind spectacle lens of the present embodiment, carried out when needing to treat grind spectacle lens 50
When depth is ground, adjusting rod 42 is pulled out from adjusting cavity 40, makes adjusting rod 42 that connecting rod 43 be driven to make under 41 top of telescopic rod
Drop, the gap between 41 top of telescopic rod and the second connecting tube 22 increase, and more lapping liquids is made to flow into adjusting cavity from water storage cavity 33
In 40, make adjusting cavity 40 with the water increase in adjusting cavity 40 and relative to 22 descending motion of the second connecting tube, at the same time,
Due to the decline of adjusting cavity 40, increase grinding head 51 and the contact surface of eyeglass 50 to be ground, so as to treat grind spectacle lens
50 carry out depth grinding；When needing to treat the progress either shallow grinding of grind spectacle lens 50, adjusting rod 42 is inwardly drawn from adjusting cavity 40
It is dynamic, make adjusting rod 42 that connecting rod 43 be driven to make to rise at the top of telescopic rod 41, the seam between 41 top of telescopic rod and the second connecting tube 22
Gap reduces, and reduces the water that lapping liquid flows into adjusting cavity 40 from water storage cavity 33, makes adjusting cavity 40 with the water in adjusting cavity 40
Amount reduce and relative to 22 ascending motion of the second connecting tube, at the same time, due to the rising of adjusting cavity 40, make grinding head 51 with to
The contact surface of grind spectacle lens 50 is reduced, and carries out either shallow grinding so as to treat grind spectacle lens 50.
In addition, it should be noted that, the specific embodiments described in this specification, the shape of parts and components are named
Title etc. can be different.The equivalent or simple change that all structure, feature and principles described according to the invention patent design are done, is wrapped
It includes in the scope of protection of the patent of the present invention.Those skilled in the art can be to described specific implementation
Example is done various modifications or additions or is substituted in a similar manner, and without departing from structure of the invention or surmounts this
Range as defined in the claims, is within the scope of protection of the invention.
