Abstract
The utility model relates to a bearing seat device used for positioning ball screws of an nc (numerical control) lathe, which is a part in the nc lathe and comprises a bearing seat. The utility model is characterized in that the bearing seat device used for positioning the ball screws of the nc lathe also comprises an outer spacer and positioning pins, wherein the outer spacer is in transitional match with the bearing seat and is connected with the bearing seat through positioning pins. The utility model has reasonable structure design, enables the bearing seat to be processed easily and assembled simply due to the arrangement of the outer spacer and the positioning pins so as to improve the transmission accuracy and the positioning accuracy of the ball screws.
Description
Technical field
The utility model relates to a kind of numerically controlled lathe ball-screw location and uses bearing holder device, and it belongs to the lathe mechanical field, is parts in the numerically controlled lathe.
Background technology
In the prior art, what numerically controlled lathe ball-screw positioning end structure was commonly used has two kinds, first kind of structure as shown in Figure 1, bearing block requires end face 1 perpendicular to Φ 1, end face 2 is perpendicular to Φ 2, and Φ 1 is coaxial with Φ 2; But often do not reach this three requirements in actual machined, this has just influenced the transmission accuracy and the positioning accuracy of the ball-screw after the assembling; Second kind of structure as shown in Figure 2, bearing block requires end face 1, end face 2 all perpendicular to Φ 1, though this difficulty in actual machined is littler than first kind of structure, but because end face is darker, can't observe during machined, also secondary method is measured, so still be difficult to reach requirement, the transmission accuracy and the positioning accuracy of the ball-screw after still influence is assembled.
Summary of the invention
The purpose of this utility model is to overcome existing above-mentioned deficiency in the prior art, and a kind of reasonable in design, the simple numerically controlled lathe ball-screw of process and assemble location bearing holder device are provided.
The technical scheme in the invention for solving the above technical problem is: this numerically controlled lathe ball-screw location comprises bearing block with bearing holder device, it is characterized in that also being provided with outer separator and alignment pin, outer separator and described bearing block interference fits, and outer separator is connected by alignment pin with bearing block.
Alignment pin described in the utility model has two.
The utility model its beneficial effect compared with the prior art is: reasonable in design owing to be provided with outer separator and alignment pin, the processing of bearing block is become easily, assemble also simple, thereby improved the transmission accuracy and the positioning accuracy of ball-screw.
Description of drawings
Fig. 1 is a bearing block structure schematic diagram of the prior art;
Fig. 2 is an another kind of bearing block structure schematic diagram of the prior art;
Fig. 3 structural representation of the present utility model.
Fig. 4 is the A-A cutaway view of Fig. 3.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Referring to Fig. 3-Fig. 4, the utility model comprises bearing block 3, outer separator 4 and alignment pin 5, outer separator 4 and described bearing block 3 interference fits, and outer separator 4 is connected by two alignment pins 5 with bearing block 3.The maximum characteristics of this structure are that bearing holder device processing is become easily, assemble also simple; During installation, only need dress up assembly earlier, reinstall bearing block 3, stamp two alignment pins 5 at last, promptly finish assembling.
Need to prove, allly conceive equivalence or the simple change that described structure and feature are done, be included in the protection domain of the present utility model according to the utility model.
