The purpose of this utility model provides a kind of guide rail structure of accurate coordinate table, the steel ball of double V-shaped groove and two row's interference fit is set on each moving guide rail of planker 2 above and belows, influence with the transverse pressure of eliminating interference fit, simultaneously be provided with the auxiliary guide rail pair in the inboard of main guide rail pair, when workpiece weight is excessive, the auxiliary guide rail pair begins to work, and avoids the excessive distortion of working plate 3 and planker 2, thereby realizes improving the purpose of machining accuracy.
Description of drawings:
Fig. 1 is that the x of existing coordinate table is to the guide rail structural representation.
Fig. 2 is that x of the present utility model is to the guide rail structural representation.
Fig. 3 is that y of the present utility model is to the guide rail structural representation.
Realize that the utility model purpose technical measures are: the moving guide rail in the main guide rail pair adopts double V-shaped structure, eliminates the working plate flexural deformation that interference fit causes; Simultaneously in the inboard of a pair of main guide rail pair a pair of auxiliary guide rail pair is set, when service weight is excessive, prevents that working plate and planker excessively are out of shape.
Below in conjunction with description of drawings, be described in detail particular content of the present utility model.
The guide rail structure of accurate coordinate table of the present utility model comprises x to guide rail, and y is characterized in that to guide rail:
---x contains secondary and two the auxiliary guide rail pairs of two main guide rails to guide rail, each main guide rail pair is made up of steel ball A, the B of quiet guide rail 11,12, moving guide rail 21, band isolating frame, respectively establish a V-type groove on the wherein quiet guide rail 11,12, be connected with support 1 respectively, moving guide rail 21 bottoms are provided with two V-type grooves, fixedly connected with planker 2 in its top, steel ball A, the B of band isolating frame are arranged between two pairs of V-type grooves of dynamic and static guide rail 21,11,12, adopts interference fit to connect; It is secondary inboard that the auxiliary guide rail pair is positioned at main guide rail, each auxiliary guide rail pair is made up of quiet guide rail 13, pedestal 22, axle 23, ball bearing 24, wherein pedestal 22 bottoms are provided with a through hole that is used to arrange bearing 23, fixedly connected with planker 2 in its top, ball bearing 24 is installed on the axle 23, and contacts with quiet guide rail 13;
---y contains secondary and two the auxiliary guide rail pairs of two main guide rails to guide rail, each main guide rail pair by quiet guide rail 21 ', 22 ', steel ball C, the D of moving guide rail 31, band isolating frame form, wherein quiet guide rail 21 ', 22 ' on respectively establish a V-type groove, fixedly connected with planker 2 respectively, moving guide rail 31 bottoms are provided with two V-type grooves, fixedly connected with working plate 3 in its top, steel ball C, the D of band isolating frame be arranged in dynamic and static guide rail 31,21 ', 22 ' two pairs of V-type grooves between, adopt interference fit to connect; It is secondary inboard that the auxiliary guide rail pair is positioned at main guide rail, each auxiliary guide rail pair by quiet guide rail 23 ', pedestal 32, axle 33, ball bearing 34 forms, wherein pedestal 32 bottoms are provided with a through hole that is used for disposed axle 33, fixedly connected with working plate 3 in its top, ball bearing 34 is installed on the axle 33, and with quiet guide rail 23 ' contact.
When the screw rod Lx between planker 2 and support 1 rotated, the nut Mx that matches with screw rod Lx drove planker 2 moving linearlies; When the screw rod Ly between planker 2 and working plate 3 rotated, the nut My that matches with screw rod Ly drove working plate 3 moving linearlies.
