Abstract
The invention relates to the field of a carbon fiber composite shaft head connection method, particularly a carbon fiber roll shaft head connection structure and method. The connection structure is characterized by comprising a pipe and a shaft head, wherein the front of the shaft head is provided with a polygonal structure; and the length of any diagonal line of the polygon is less than the internal diameter of the pipe. The connection method comprises the following steps: 1) grinding the front of the shaft head to obtain polygonal edges; 2) connecting the ground shaft heads in an interaction mode; 3) punching the superposition position of the shaft head front end and pipe by using a puncher, inserting a pin, and fixing; 4) filling a resin into the gap between the shaft head and pipe; and 5) curing the resin. The method can convert the force borne by the resin from shearing force into extrusion force, thereby enhancing the maximum bearing force and durability of the connecting shaft and solving the problem of high tendency to shedding and damage of the resin.
Description
Technical field
The present invention relates to the connecting means of a kind of carbon fiber composite spindle nose, be specifically related to the connecting means of a kind of carbon fiber roll shaft spindle nose.
Background technique
In prior art, in band large-scale metal axle weight, and its processibility and dynamic characteristic are not fine, and carbon fiber composite axoplasm amount is light, and intensity is high to be met under equal performance requirement, and its weight can alleviate more than 60%; Carbon fiber composite has good fatigue resistance and corrosion resistance, and noise is low, and vibration attenuation is good.Current carbon fiber roller bearing and working in coordination of pipe material inner wall are against resin-bonding or mechanical connection, when resin-bonding, when axle rotates time, resin will bear the effect of shearing force, and brute force when resin bears shearing force and patience can be poor, resin easily comes off, damage.
The patent No. is the linkage structure that the Chinese patent of CN201410033858.8 discloses a kind of carbon fiber axle and metal shaft, its structure is: be made up of polygonal metal end (1) and carbon fiber composite axle (2), the two ends of described carbon fiber composite axle form the polygonal consistent with the end shape of polygonal metal end by techniques such as windings, and it adopts splicing form to be connected with polygonal metal end end; Or be made up of polygonal metal end (1), inner metallic layer (3) and carbon fiber pipe (4), wherein polygonal metal end end adopts socket form to be connected with the polygonal hole of the inside of inner metallic layer; Described carbon fiber pipe is wrapped on the outer surface of inner metallic layer, and utilizes resin to be connected and fixed.The connection that the present invention overcomes metal and carbon fiber composite axle is not enough, when ensureing that the continuity of carbon fiber composite axle fiber is not destroyed, by changing the sectional shape of metal and carbon fiber shaft connection place, improve the join strength of metal and carbon fiber composite axle, this patent specification has set forth the linkage structure of a kind of carbon fiber axle and metal shaft, and the full content of this patent is quoted at this as prior art.
Summary of the invention
The invention provides a kind of carbon fiber roll shaft spindle head connecting structure and method thereof, solve with resin carry out spindle nose connect time, resin easily comes off, the problem of damage.
The technological scheme that the present invention specifically adopts is:
A kind of carbon fiber roll shaft spindle head connecting structure, it is characterized in that: comprise pipe and spindle nose, described spindle nose front portion is provided with polygon structure, and described polygonal any cornerwise length is all less than ips, can make like this to vacate gap between pipe and spindle nose.
Wherein, described spindle nose front end is connected with pipe by pin, firm fixed effect.
Wherein, described polygonal is regular polygon, and limit number is 3 ~ 6.
Wherein, outside described polygonal and be provided with resin between pipe.
A method for carbon fiber roll shaft spindle head connecting structure, is characterized in that: comprise the steps:
1) the anterior break-in of spindle nose is gone out polygonal corner angle;
2) spindle nose of break-in is connected with cooperatively interacting;
3) with punching machine, punched in spindle nose front end and pipe overlapping part, insert pin and fix;
4) resin is filled with in the space between spindle nose and pipe;
5) cured resin.
The beneficial effect of this method is:
Resin needs the conversion of the shearing force of bearing in order to extruding force by the present invention originally, enhances maximum strength and resisting power, without the need to frequent replacing, present invention also adds the fixation of pin, more enhance the stability of connection, improve working efficiency.
Accompanying drawing explanation
Fig. 1 is that spindle nose of the present invention connects schematic cross-section;
Fig. 2 is the schematic cross-section that the anterior polygonal of spindle nose of the present invention connects.
In figure, 1-pipe 2-spindle nose 3-resin 4-pin.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
As shown in Fig. 1 ~ 2, a kind of carbon fiber roll shaft spindle head connecting structure, comprises pipe and spindle nose, spindle nose front portion is provided with regular polygon structure, the limit number of regular polygon is 5, and any cornerwise length is all less than ips, and spindle nose front end is connected with pipe by pin.
The connecting means of a kind of carbon fiber roll shaft spindle nose, is characterized in that: comprise the steps:
1) the anterior break-in of spindle nose is gone out polygonal corner angle;
2) spindle nose of break-in is connected with cooperatively interacting;
3) with punching machine, punched in spindle nose front end and pipe overlapping part, insert pin and fix;
4) resin is filled with in the space between spindle nose and pipe;
5) cured resin.
