Abstract
The invention relates to a working table structure used in an improved vertical type grinding machine. The working table structure has the advantages of high precision, good rigidity, strong supporting capacity and abrasion resistance and consists of a flange, an electric magnetic chuck and a belt pulley; the flange is provided with the electric magnetic chuck and installed on a shackle which is mounted at the machine body by a support, the exterior of the shackle is sheathed with the belt pulley, the central bottom of the flange is installed on the machine body by a support; the working table structure is characterized in that: the support between the shackle and the machine body is a closed hydrostatic guideway support, while the support between the central bottom of the flange and the machine body is a radial hydrostatic bearing support.
Description
(1) technical field
The present invention relates to the grinding machine components technical field, be specially a kind of vertical grinder Working table structure.
(2) background technology
Traditional vertical grinder Working table structure, it comprises and connects dish, and the described dish that connects is gone up magnechuck is installed, and the described dish that connects is installed on lathe bed, motor drives belt pulley and connects dish and magnechuck revolution by the torsion shaft drive by decelerator and belt during its work, the shortcoming of this structure is that radial ball bearing centering is radially adopted in its revolution, and axially adopts plane roller bearing to fix, like this during work table rotation, bearing is easy to wear, cause whole Working table structure poor rigidity, bearing capacity is little, and precision is low.
(3) summary of the invention
At the problems referred to above, the invention provides a kind of vertical grinder Working table structure, its precision height, good rigidly, bearing capacity is strong, and is not easy to wear.
Its technical scheme is: it comprises and connects dish, magnechuck, belt wheel, described connecing is equipped with magnechuck on the dish, the described dish that connects is installed on T-Ring, described T-Ring is installed on lathe bed by supporting, the outer cover of T-Ring is equipped with belt wheel, described connect dish center bottom be installed on lathe bed by supporting, it is characterized in that: the supporting between described T-Ring and the described lathe bed is closed hydrostatic slideway supporting; Described center bottom and the supporting between the lathe bed that connects dish is radially hydrostatic bearing supporting.
It is further characterized in that: described closed hydrostatic slideway supporting comprises upper support piece, lower support piece, the top of described upper support piece is pressed with pressure ring, pressure ring is connected with lathe bed, described lower support piece is connected with cushion block, described cushion block is connected with described lathe bed, is pressure oil cavity between described upper support piece, lower support piece and the described T-Ring; Described radially hydrostatic bearing comprises revolving body, fixed body, described revolving body with connect the dish be connected, described fixed body is installed on base, described base is installed on lathe bed, is high-voltage oil cavity between revolving body and the fixed body.
In the said structure of the present invention, the closed hydrostatic slideway supporting can be controlled the axial float of workbench, and radially hydrostatic bearing can control the circular runout of workbench, the magnechuck revolution steadily, as long as oil supply system is normal, the working table movement part is never wornout, guarantees rigidity, bearing capacity and the precision of work.
(4) description of drawings
Fig. 1 is the cutaway view of structural front view of the present invention;
Fig. 2 is the vertical view of Working table structure among Fig. 1.
(5) specific embodiment
See Fig. 1, Fig. 2, the present invention includes and connect dish 1, magnechuck 2, belt wheel 3, connect on the dish 1 magnechuck 2 is installed, connect dish 1 and be installed on T-Ring 9, T-Ring 9 is installed on lathe bed 8 by supporting, this supporting is closed hydrostatic slideway, the outer cover of T-Ring 9 is equipped with belt wheel 3, connects dish 1 center bottom and is installed on lathe bed 8 by supporting, and this supporting is hydrostatic bearing radially, described closed hydrostatic slideway supporting comprises upper support piece 4, lower support piece 5, the top of upper support piece 4 is pressed with pressure ring 6, and pressure ring 6 is connected with lathe bed 8, and lower support piece 5 is connected with cushion block 7, cushion block 7 is connected with lathe bed 8, upper support piece 4, be pressure oil cavity between lower support piece 5 and the T-Ring 9; Described radially hydrostatic bearing comprises revolving body 10, fixed body 11, revolving body 10 with connect dish and 1 be connected, fixed body 11 is installed on base 12, base 12 is installed on lathe bed 8, be high-voltage oil cavity between revolving body 10 and the fixed body 11, narrow V belt 16, belt wheel 17 play the effect with narrow V belt 13 tensionings.
