Description

Boring machine main shaft reinforcing sleeve

Technical Field

The utility model belongs to the technical field of the boring machine accessory, concretely relates to boring machine main shaft uide bushing.

Background

The boring machine is a machine tool which mainly uses a boring cutter to bore the existing prefabricated holes of workpieces. Typically, the boring tool rotation is the primary motion and the boring tool or workpiece movement is the feed motion. It is mainly used for machining high-precision holes or finishing multiple holes by one-time positioning, and can also be used for machining other machining surfaces related to hole finishing. The machining precision and the surface quality of drilling, milling and cutting can be higher than those of a drilling machine by using different tools and accessories. The boring machine is the main equipment for processing large box parts.

The existing boring machine finds that the boring machine main shaft has poor rigidity when needing to be stretched and processed, is easy to vibrate, has low feeding rate and low efficiency, and the processing precision can not meet the requirement.

SUMMERY OF THE UTILITY MODEL

To solve the problems set forth in the background art described above. The utility model provides a boring machine main shaft reinforcing sleeve has the rigidity of having strengthened the main shaft greatly, and machining efficiency obviously improves characteristics.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a boring machine main shaft reinforcing sleeve, includes the main shaft square, and the intermediate position of main shaft square rotates and is connected with extension main shaft, and the one end that the main shaft square was kept away from to extension main shaft is connected with the blade disc, and the cover has the reinforcing sleeve body on the circumference of extension main shaft.

As the utility model discloses a preferred technical scheme, the diameter ratio that the reinforcement sleeve body is close to main shaft square one end is kept away from the diameter of main shaft square one end greatly.

As the preferred technical scheme of the utility model, a plurality of notch have been seted up on the circumference that the reinforcement sleeve body is close to main shaft square one end evenly.

As the preferred technical scheme of the utility model, set up on the lateral wall of notch near main shaft square one side with main shaft square looks vertically hole.

As the utility model discloses a preferred technical scheme, run through female connection through the screw between reinforcement sleeve body and the main shaft bearing.

As the preferred technical scheme of the utility model, the reinforcement sleeve body is spring steel 65Mn component.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses the cover has a reinforcement sleeve body on the circumference of extension main shaft, and the diameter ratio that the reinforcement sleeve body is close to main shaft square one end is big that main shaft square one end was kept away from to the diameter ratio, and the reinforcement sleeve body rotates with extension main shaft simultaneously, has strengthened the rigidity of extension main shaft greatly to machining efficiency has been improved.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Examples

Referring to fig. 1-2, the present invention provides the following technical solutions: the utility model provides a boring machine main shaft reinforcing sleeve, includes main shaft square 1, and the intermediate position of main shaft square 1 is connected with extension main shaft 4 through the bearing rotation, and the one end that main shaft square 1 was kept away from to extension main shaft 4 is connected with blade disc 5, and the cover has on the circumference of extension main shaft 4 and strengthens set body 3.

Specifically, the diameter of the end of the reinforcing sleeve body 3 close to the spindle block 1 is larger than the diameter of the end far away from the spindle block 1.

Through adopting above-mentioned technical scheme, the diameter ratio that is close to main shaft square 1 one end is 3cm big than the diameter of keeping away from main shaft square 1 one end, makes the rigidity of strengthening sleeve body 3 better.

Specifically, a plurality of notches 2 are uniformly formed in the circumference of one end, close to the main shaft square 1, of the reinforcing sleeve body 3.

Through adopting above-mentioned technical scheme, four notches 2 have been seted up to this embodiment, and the convenience is connected the reinforcement sleeve body 3 with main shaft bearing.

Specifically, an inner hole 6 perpendicular to the main shaft square block 1 is formed in the side wall of the notch 2 close to one side of the main shaft square block 1, and the reinforcing sleeve body 3 is connected with the main shaft bearing through the inner hole 6 through a screw.

By adopting the technical scheme, the screw penetrates through the inner hole 6 to be meshed with the inner ring of the main shaft bearing, so that the reinforcing sleeve body 3 and the lengthened main shaft 4 can rotate simultaneously.

Specifically, the reinforcing sleeve body 3 is a spring steel 65Mn member.

To sum up, the utility model discloses the cover has a reinforcement sleeve body 3 on the circumference of extension main shaft 4, and the diameter ratio that reinforcement sleeve body 3 is close to 1 one end of main shaft square is big that main shaft square 1 one end was kept away from to the diameter ratio, and reinforcement sleeve body 3 rotates with extension main shaft 4 simultaneously, has strengthened the rigidity of extension main shaft 4 greatly to machining efficiency has been improved.
