Abstract
The utility model discloses a plane polishing and grinding device for an electrolytic copper foil cathode roller. The plane polishing and grinding device comprises a main shaft box body (14), wherein a pushing assembly (15) is arranged below the main shaft box body (14); the main shaft box body (14) is provided with a main driving shaft (13); the main driving shaft (13) is sequentially and fixedly provided with three sets of angular contact bearings (9), two sets of parallel-connected angular contact bearings (7) and double rows of short cylindrical roller bearings (6) from left to right; the left and right ends of the main driving shaft (13) are exposed out of the main shaft box body (14); the leftmost end of the main driving shaft (13) is provided with a belt wheel (12) and the rightmost end of the main driving shaft (13) is provided with a plane grinding wheel (2). According to the plane polishing and grinding device for the electrolytic copper foil cathode roller, the disadvantages of existing polishing and grinding equipment that the unit area of cuttings is small, and low roughness, low outer roundness of the roller surface, low straight degree and low jumping precision are caused by the fact that a roller surface has obvious trembled lines can be overcome.
Description
Technical field
The utility model relates to a kind of cathode roll plane polishing and grinding apparatus of electrolytic copper foil cathode roll plane polishing and grinding apparatus, particularly a kind of electrolytic copper foil of using for printed circuit.
Background technology
Printed circuit Copper Foil is that cation is shifted to cathode roll under electric field action, and anion is shifted to anode, carries out electrochemical reaction.That is:
On cathode roll, be reduced into copper
On negative electrode, be reduced into hydrogen
In raw paper tinsel electrolytic process, the surface condition of cathode base material, the metal pretreatment of surface roughness and cathode roller produces huge decisive action to electrolytic copper foil texture evolution as machine glazed finish, chemistry and electrochemical polish.Cathode roll surface crystal structures shape the initial crystalline state of electrolytic copper foil.
Conventional cathode roller rubbing down mode has: abrasive belt rubbing down, outer round type rubbing down, but there is use limitation in these two kinds of rubbing down modes, and disposable use and cost are high.And conventional outer round type rubbing down exists that smear metal unit are is little, roll surface exists that the line that obviously trembles causes that roughness is low, roll surface outer circularity, linearity, drawback that the precision of beating is low.What main cause was its power transmission shaft employing is common bearing shell, lubricated oil cooled mode, cathode roll is because diameter is greater than 2m, in the process of rubbing down, have larger axial force and radial load, and bearing shell cannot bear larger axial impact force, so the line that trembles is obvious.
Utility model content
The purpose of this utility model is, a kind of electrolytic copper foil cathode roll plane polishing and grinding apparatus is provided.The utility model can solve that existing rubbing down equipment smear metal unit are is little, roll surface exists that the line that obviously trembles causes that roughness is low, roll surface outer circularity, linearity, drawback that the precision of beating is low.
The technical solution of the utility model: a kind of electrolytic copper foil cathode roll plane polishing and grinding apparatus, is characterized in: comprise main spindle box body, main spindle box body below is provided with pushing component; Described main spindle box body is provided with final drive shaft; On described final drive shaft, be fixed with successively from left to right three groups of angular contact bearings, two groups of angular contact bearings that are connected in parallel and double row cylindrical roller bearing; Main spindle box body is exposed at the two ends, left and right of final drive shaft, and high order end is provided with belt pulley, and low order end is provided with
flat-faced wheel.Final drive shaft is supported in main spindle box body by three groups of angular contact bearings on the left side and the angular contact bearing being connected in parallel and the double row cylindrical roller bearing on the right.
In above-mentioned electrolytic copper foil cathode roll plane polishing and grinding apparatus, described main spindle box body both sides are also provided with left platen and right platen is fixed final drive shaft; In described left platen, be also provided with deep groove ball bearing, the inner ring of deep groove ball bearing is fixed on final drive shaft.
In aforesaid electrolytic copper foil cathode roll plane polishing and grinding apparatus, the right-hand member of described three groups of angular contact bearings is also provided with spring and thrust pad.Thrust pad is used for propping up spring.
In aforesaid electrolytic copper foil cathode roll plane polishing and grinding apparatus, described in
flat-faced wheel is fixed on main shaft chuck by grinding wheel chuck, and main shaft chuck is fixed on final drive shaft.
Compared with prior art, the utility model, in order to bear extremely strong have axial and radial thrust, has designed double row cylindrical roller bearing and deep groove ball bearing, can bear respectively the axial force of axial forward end and end; And five groups of angular contact ball bearings can bear extremely strong radial thrust, for eliminating the play of radial load, ad hoc one group of spring and the thrust pad counted, stability while rotating to reach adjustment.Empirical tests, device of the present utility model has following some advantage:
1, emery wheel can bear very strong radial thrust, axial thrust, guarantees the stability of emery wheel High Rotation Speed;
2, emery wheel smear metal unit are is large, is at least 5 times of cylindrical smear metal area, and roll surface linearity is fabulous;
3, long service life, is the more than 10 times of plain wheel life-span, and cost is extremely low, has higher economic benefit.
