Embodiment

The application is described in further detail with reference to the accompanying drawings and examples.It is understood that this place is retouched The specific embodiment stated is used only for explaining related invention, rather than the restriction to the invention.It also should be noted that, in order to It is easy to illustrate only the part related to invention in description, accompanying drawing.

It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the application can phase Mutually combination.Describe the application in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

Fig. 1 be refer to for a kind of a kind of structural representation of embodiment of bicycle rim bar cap locking device of the application, should Device includes lower mould 10, the upper mould for being used to fix and control rim to rotate positioned at the lower top of mould 10 for being used to place rim Tool 20 and the equally distributed bar cap locking device 30 of excircle along rim；Also include be located at bar cap locking device 30 between can Along the sanding apparatus 40 of rim radial expansion.

In a preferred embodiment, the sanding apparatus 40 include cylinder 41 and be fixed on the piston rod of cylinder 41 can The brush stroke 42 stretched into rim excircle.After rim is placed on lower mould 10, mold 20, which is moved down, fixes rim；Bar cap Locking device 30 starts locking action, and cylinder 41, which stretches out, stretches into brush stroke 42 in the excircle of rim；Mold 20 is opened simultaneously It is dynamic to drive rim steppingly to rotate；Rim is polished device 40 when rotation and grinds off burr, fully by the rotation of rim Time and action have saved the time of independent deburring using deburring is carried out.

As shown in Fig. 2 the sanding apparatus 40 includes cylinder 41, is fixed on the piston of cylinder 41 in a preferred embodiment The brush stroke 42 that hairbrush fixed mount 43 on bar and be fixed on hairbrush fixed mount 43 two can be stretched into rim excircle； The hairbrush fixed mount 43 includes fixed block 44 and be fixed on the disk roller 45 of the lower section of fixed block 44 with can horizontally rotating；The fixation The side of block 44 towards rim offers the regulation passage of strip；Sliding block is slideably connected with the regulation passage；Institute The two ends of sliding block are stated by being fixedly connected through the fixed block and the steel wire rope 46 that is wound on disk roller；Two brush strokes 42 are fixed At the two ends of the sliding block；The center of the disk roller is extended with regulation handle.The life-span of brush stroke 42 is limitedly, it is necessary to frequently Ground is changed, in order that not influenceing the bar cap of bicycle rim to lock and sanding burr when must changing brush stroke 42, is utilized The time of rim is changed, disk roller is rotated so that new brush stroke 42 is moved to the center of regulation passage, while the brush stroke of abrasion 42 are moved to the end of regulation passage, when new brush stroke 42 works, can be changed the brush stroke 42 of abrasion.
