4. The split ball nut structure of claim 2, wherein: the circumferential direction of the flange plate (2) is provided with a plurality of countersunk holes (22).

The technical field is as follows:

the invention relates to a split type ball nut structure.

Background art:

the traditional ball nut is mainly connected with a nut seat of a user by virtue of mounting holes on the ball nut, and in the actual use process, even when the matching excircle of the ball nut is consistent, the sizes, the numbers, the center distances, the flange chamfered edges, the oil hole positions, the oil hole types and the like of the mounting holes on the nuts of different users are different, so that the types of the nuts are various, the manufacturing cost is high, the period is long (the traditional ball nut needs to be forged, and the period of the photo-thermal treatment forging processing needs about 20 days), and the other machining time is calculated additionally. Along with the development of a machine tool, fewer and fewer installation occasions depend on the matching excircle phi d, more and more positioning modes depend on end face fixing, and time and labor are wasted in the manufacturing of the traditional ball nut.

The invention content is as follows:

the invention provides a split type ball nut structure, which is based on the fact that more and more end face positioning situations are generated when a ball nut is installed, namely, the positioning by virtue of an excircle is weakened, so that the following split type structure of a ball nut flange is provided, the production efficiency is improved, and the cost is reduced.

The technical scheme adopted by the invention is as follows: the utility model provides a split type ball nut structure, includes straight nut, ring flange and locking screw, through locking screw fixed connection between straight nut and the ring flange, and straight nut and the coaxial setting of ring flange.

Furthermore, a plurality of through holes are formed in the circumferential direction of the flange plate, a plurality of threaded holes are formed in the end face of one side of the straight barrel nut, and the locking screws penetrate through the through holes and are in threaded connection with the threaded holes.

Further, the through hole is a cylindrical hole.

Furthermore, a plurality of counter bores are formed in the circumferential direction of the flange plate.

The invention has the following beneficial effects:

based on the defects of long manufacturing period and high cost of the traditional ball nut, the invention provides an optimization scheme aiming at shortening the manufacturing period, improving the efficiency and reducing the manufacturing cost.

Description of the drawings:

FIG. 1 is a block diagram of the present invention.

Fig. 2 is a structural diagram of the application of the present invention.

The specific implementation mode is as follows:

the invention will be further described with reference to the accompanying drawings.

Referring to fig. 1 and 2, the split ball nut structure of the present invention includes a straight nut 1, a flange 2 and a locking screw 3, wherein the straight nut 1 and the flange 2 are fixedly connected through the locking screw 3, and the straight nut 1 and the flange 2 are coaxially disposed.

A plurality of through holes 21 are arranged in the circumferential direction of the flange plate 2, and the through holes 21 are cylindrical holes. A plurality of threaded holes 11 are formed in the end face of one side of the straight barrel nut 1, and the locking screw 3 penetrates through the through hole 21 and is in threaded connection with the threaded holes 11.

A plurality of counter bores 22 are arranged in the circumferential direction of the flange plate 2, and the counter bores 22 are used for being fixedly connected with a user nut seat.

The straight barrel nut 1 can be processed in batches for use without being mounted by matching with the excircle phi d, is used as a standard part for manufacturing a warehouse, and does not need forging, so that the period and the cost are saved;

the flange plate 2 is processed in real time according to the characteristics of users (such as the type and the angle of a mounting hole, the edge cutting of a flange, the position of an oil hole and the like); compared with the traditional integral ball nut, the integral ball nut only needs to manufacture a plurality of flange plates; the manufacturing time of each flange plate is about 4-7 days, and compared with the photo-thermal forging time of the traditional integral ball nut structure, the photo-thermal forging time is reduced by a large amount; the cost and the period are greatly reduced, for example, as follows.

Based on the defects of long manufacturing period and high cost of the traditional ball nut, the invention provides an optimization scheme aiming at shortening the manufacturing period, improving the efficiency and reducing the manufacturing cost.

The foregoing is only a preferred embodiment of this invention and it should be noted that modifications can be made by those skilled in the art without departing from the principle of the invention and these modifications should also be considered as the protection scope of the invention.
