Abstract
The purpose of this utility model proposes a kind of combined type rotation shaft, to improve the manufacturing efficiency of rotating shaft.Combined type rotation shaft of the present utility model comprises rotating shaft body and pad, and the central authorities of described pad are provided with through hole, the sheathed tail end being fixed on rotating shaft body of described pad.Because the rotating shaft of combinations thereof formula is combined by rotating shaft body and pad, rotating shaft body can be completed by forging or milling process adding man-hour, and easy to process, and pad can complete in punching press, processes also very convenient, thus improves manufacturing efficiency.
Description
Technical field
The utility model relates to a kind of turning gear, the rotating shaft of specifically a kind of notebook computer or the use of integrated computer product.
Background technique
The effect of pivot joint is played in the rotating shaft that notebook computer or integrated computer product use, and enables display device, keyboard relatively rotates.The rotating shaft that current notebook computer or integrated computer product use is integral type, formed through turnery processing by axle center, pad diameter due to rotating shaft tail end is greater than the diameter of rotating shaft body, and therefore the turning operation of rotating shaft body middle position is very complicated, causes manufacturing efficiency low.
Model utility content
The purpose of this utility model proposes a kind of combined type rotation shaft, to improve the manufacturing efficiency of rotating shaft.
Combined type rotation shaft of the present utility model comprises rotating shaft body and pad, and the central authorities of described pad are provided with through hole, the sheathed tail end being fixed on rotating shaft body of described pad.Because the rotating shaft of combinations thereof formula is combined by rotating shaft body and pad, rotating shaft body can be completed by forging or milling process adding man-hour, and easy to process, and pad can complete in punching press, processes also very convenient, thus improves manufacturing efficiency.
Further, the tail end of described rotating shaft body is made up of the positioning section of cylindric carrying section and end, and the sidepiece of described positioning section is provided with cutting face; The shape of through holes of described pad and the shape of rotating shaft body tail end suitable.Carrying section being combined for fixing the installation of pad with positioning section, not only can ensure the stability of pad, effectively preventing from occurring relatively rotating between pad and rotating shaft body, the tail end intensity of rotating shaft body can also be improved.
Further, for ease of installing pad, the end of described positioning section is provided with guiding surface.
After the utility model changes traditional integral type rotating shaft into combined type rotation shaft, forging method production rotating shaft body can be utilized, process for stamping is utilized to produce pad, and then rotating shaft body and pad are fixed together, form combined type rotation shaft, because punching press is high with forging efficiency, solve the problem that manufacturing efficiency is low greatly.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of combined type rotation shaft of the present utility model.
Fig. 2 is the structural representation of pad of the present utility model.
Fig. 3 is the structural representation of rotating shaft body of the present utility model.
Embodiment
Contrast accompanying drawing below, by the description to embodiment, the effect and working principle etc. of embodiment of the present utility model as the mutual alignment between the shape of involved each component, structure, each several part and annexation, each several part are described in further detail.
Embodiment 1:
As shown in the figure, the combined type rotation shaft of the present embodiment comprises rotating shaft body 1 and pad 2, and the central authorities of described pad 2 are provided with through hole 21, the sheathed tail end being fixed on rotating shaft body 1 of described pad 2.
The tail end of rotating shaft body 1 is made up of the positioning section 12 of cylindric carrying section 11 and end, and the sidepiece of described positioning section 12 is provided with cutting face 13; Through hole 21 shape of described pad 2 and the shape of rotating shaft body 1 tail end suitable.Carrying section 11 being combined for fixing the installation of pad 2 with positioning section 12, not only can ensure the stability of pad 2, effectively preventing from occurring relatively rotating between pad 2 and rotating shaft body 1, the tail end intensity of rotating shaft body 1 can also be improved.
For ease of installing pad 2, the end of described positioning section 12 is provided with guiding surface 14.
Because the rotating shaft of combinations thereof formula is combined by rotating shaft body 1 and pad 2, rotating shaft body 1 add man-hour can by forging or milling process complete, and it is easy to process, and pad 2 can complete in punching press, process also very convenient, after rotating shaft body 1 and pad 2 being machined respectively, utilize fixture rotating shaft body 1 and pad 2 pressing to be fixed together, form combined type rotation shaft, thus improve manufacturing efficiency.
Claims (2)
1. a combined type rotation shaft, it is characterized in that comprising rotating shaft body and pad, the central authorities of described pad are provided with through hole, the sheathed tail end being fixed on rotating shaft body of described pad; The tail end of described rotating shaft body is made up of the positioning section of cylindric carrying section and end, and the sidepiece of described positioning section is provided with cutting face; The shape of through holes of described pad and the shape of rotating shaft body tail end suitable.
