Abstract
The utility model discloses a numerically controlled lathe with strong carrying capacity and stable operation, which comprises a lathe body and a main spindle box arranged thereon, wherein the main spindle box is provided with a cavity; a main splindle is arranged in the cavity; bearings are arranged between the periphery of the main splindle and the inner wall of the cavity; three pairs of bearings are arranged at the periphery of the front end of the main splindle, wherein the two pairs of bearings are arranged side by side, and the other pair of bearings are arranged at intervals; and two pairs of bearings are arranged at the periphery of the back end of the main splindle and arranged side by side. The utility model is suitable for numerically controlled lathes.
Description
Technical field
The utility model relates to a kind of numerically controlled lathe, relates in particular to the numerically controlled lathe that a kind of main shaft periphery is provided with many supplementary bearings.
Background technology
Centre numerically controlled lathe comprises lathe bed, lathe bed is provided with main spindle box, and main spindle box has cavity, is provided with main shaft in the cavity, be provided with bearing between main shaft periphery and the cavity inner wall, bearing is generally positioned at the front and back end of main shaft, and quantity respectively is a pair, during owing to spindle operation, need the bigger power of carrying, and the single supplementary bearing bearing capacity in front and back is limited, thereby causes main shaft to produce the rigidity deficiency, thereby influences crudy.
The utility model content
The technical problems to be solved in the utility model provides strong, the stable numerically controlled lathe of a kind of bearing capacity.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises lathe bed, is located at the main spindle box on the lathe bed, described main spindle box has cavity, be provided with main shaft in the described cavity, be provided with bearing between described main shaft periphery and the cavity inner wall, the described number of bearings of being located at the front-end of spindle periphery is 3 pairs, and wherein 2 supplementary bearings are arranged side by side, and another supplementary bearing is provided with at interval, the number of bearings of being located at the rear-end of spindle periphery is 2 pairs, for being arranged side by side.
Because the utility model front-end of spindle adopts 3 supplementary bearings, rear end to adopt the configuration of 2 supplementary bearings, thereby can effectively improve the base bearing loading capability, makes operation more stable.
Description of drawings
Accompanying drawing is the structural representation of utility model.
The specific embodiment
Below in conjunction with the drawings and the specific embodiments the utility model is described in further detail:
As shown in drawings: the utility model comprises lathe bed 1, lathe bed 1 is provided with main spindle box 2, and main spindle box 2 has cavity 3, is provided with main shaft 4 in the cavity 3, be provided with bearing between main shaft 4 peripheries and cavity 3 inwalls, be provided with 3 supplementary bearings in main shaft 4 front end peripheries, be respectively bearing 5, bearing 6, bearing 7, its middle (center) bearing 5, bearing 6 are arranged side by side, bearing 7 is provided with at interval with bearing 5, bearing 6, be provided with 2 supplementary bearings in main shaft 4 rear end peripheries, be respectively bearing 8, bearing 9, bearing 8, bearing 9 are for being arranged side by side.
