The utility model content
The purpose of the utility model is the above-mentioned deficiency to prior art, and a kind of lathe locating clip locking structure is provided, and it is applicable to the operating mode of bearing big disturbing moment, have simple in structure, cost is lower, responding ability is strong, precision is high, the advantage of good anti-vibration.
For achieving the above object; The vertical composite guide rails of the heavy type numerical control lathe of the utility model is secondary; Comprise column, be fixed in two vertical guide rails, moving component on the column; It is characterized in that also comprising with each vertical guide rail being positioned at the two straight-line rolling pieces that two surfaces on the disturbing moment direction contact respectively that wherein a straight line scroll box is loaded in the locating slot in the moving component, in the packaged pressing plate on being fixed on moving component of another straight-line rolling; In moving component, also be provided with and the straight-line rolling piece that contacts respectively of two surfaces in addition of a vertical guide rail wherein, the direction at this place, two surfaces is vertical with the direction of disturbing moment; In moving component, also be respectively equipped with the laminating plate corresponding with each straight-line rolling piece, every block of laminating plate contacts with each self-corresponding vertical guide rail surface.
Because the two straight-line rolling pieces that are positioned on the disturbing moment direction in the moving component contact respectively with vertical guide rail two surfaces; Can bear the disturbing moment that the moving component own wt forms; Add and the straight-line rolling piece that contacts respectively of two surfaces in addition of a vertical guide rail wherein; Can in two dimensional surface, carry out spacingly to moving component, positioning accuracy is high; The structure of straight-line rolling piece and laminating plate, have again simple in structure, cost is lower, responding ability is strong, precision is high, good anti-vibration advantage.
As the further improvement of the utility model, also be associated with the adjustment pad between each straight-line rolling piece and the moving component; Can between straight-line rolling piece and guide rail, form suitable preload through the adjustment pad;
As the further improvement of the utility model, wherein also be provided with the adjustment panel between a straight line scroll box and the moving component; Through the adjustment panel, can between straight-line rolling piece and guide rail, form suitable preload equally;
As the further improvement of the utility model, said two vertical guide rails are steel guideway; Have better rigidity and wearability;
In sum, the utility model is applicable to the operating mode of bearing big disturbing moment, have simple in structure, cost is lower, responding ability is strong, precision is high, the advantage of good anti-vibration.
Description of drawings
Fig. 1 is the vertical view of the utility model embodiment.
Fig. 2 is the partial enlarged drawing at A place among Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed explanation.
By illustrated in figures 1 and 2; The vertical composite guide rails of this heavy type numerical control lathe is secondary; Comprise column 1, be fixed in two vertical guide rails 2 and 3, moving component 4 on the column 1, be positioned at the two straight-line rolling pieces 5 and 6 that two surfaces on the disturbing moment direction contact respectively with each vertical guide rail 2 and 3; Said two vertical guide rails 2 and 3 are steel guideway, and wherein a straight line scroll box 5 is loaded in the locating slot in the moving component, and another straight-line rolling piece 6 is loaded in the pressing plate 7 that is fixed on the moving component 4; In moving component 4, also be provided with the straight-line rolling piece 8 and 9 that contacts respectively with vertical guide rail 2 other two surfaces; The direction at this place, two surfaces is vertical with the direction of disturbing moment; Also be associated with adjustment pad 10 between each straight-line rolling piece and the moving component 4, also be provided with adjustment panel 11 between straight-line rolling piece 9 and the moving component 4 through screw; In moving component 4, also be respectively equipped with the laminating plate 12 corresponding with each straight-line rolling piece through bonding or injection moulding, every block of laminating plate 12 contacts with the surface of each self-corresponding vertical guide rail 2 or 3.
