Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model is not limited to following examples.
As shown in Figure 1, a kind of air supported head device, comprises shell 1, main shaft 2, swinging structure, return structure, position limiting structure.
Described swinging structure is positioned in shell swingably; Described swinging structure comprises oscillating bearing, axle sleeve; Main shaft is positioned in shell by swinging structure.
Described oscillating bearing comprises outer ring 31 and is positioned at the inner ring 32 in outer ring swingably, and the inner peripheral surface of outer ring and the outer circumference surface of inner ring are formed and be slidably matched.
Described axle sleeve is positioned in shell inner cavity swingably by oscillating bearing, and described main shaft is rotatably positioned in axle sleeve; Described axle sleeve comprises Upper shaft sleeve 41 and Lower shaft sleeve 42; Upper shaft sleeve and inner ring are fixed, and the bottom boss of Upper shaft sleeve and nut 41.1 clamp the upper and lower end face of inner ring; Lower shaft sleeve to be fixed on below Upper shaft sleeve and to stretch out shell downwards; Described main shaft is rotatably positioned in axle sleeve, and main shaft is pneumatic main shaft and inputs compressed gas-driven by external impetus mechanism (omitting in figure); After described main shaft stretches out Lower shaft sleeve downwards, also connect collet chuck 44 by short sleeve 43, folder cylinder is used for fixing grinding head (omitting in figure).
Described return structure is used for forcing swinging structure to recover vertical state, and described return structure is positioned at above oscillating bearing; In described return structure: the floating neutral block 5 of annular is fixed between shell and axle sleeve, and the circumference of floating neutral block is evenly shaped with some installing holes 52, these installing holes extend in the radial direction of floating neutral block; Form an annular pneumatic chamber 50 between the outer circumference surface of floating neutral block and the inwall of shell, described shell is shaped with the air admission hole 11 connecting atmospheric pressure cavity.
Nail 51 ecto-entad that floats inserts in installing hole, and the head of a nail of the nail that floats is positioned on the outer circumference surface of floating neutral block, and the nail bar of the nail that floats can pass through installing hole (the nail bar end of the nail that floats props up the outer circumference surface of Upper shaft sleeve) horizontally slidingly; The head of a nail of described floating nail is arranged in atmospheric pressure cavity, and the head of a nail of the nail that floats, for limiting the sliding distance of the nail that floats, prevents floating nail from excessively stretching in installing hole; Float between the nail bar of nail and installing hole and seal completely, the two ends of can ensure to float nail produce draught head, promote all floating and nail full insertion in installing hole.The number of described floating nail is identical with the number of installing hole, shows and arrange 7 installing holes altogether in figure.
Described position limiting structure, for controlling oscillating bearing scope of activities, comprises the locating slot 32.1 that is formed on inner ring outer circumference surface and is formed on the alignment pin 31.1 coordinated on outer ring and with locating slot; Described locating slot extends in the short transverse of inner ring outer circumference surface; Described position limiting structure can avoid inner ring circumference to rotate, and can also limit the pendulum angle of inner ring, prevent from causing oscillating bearing to be damaged because pendulum angle is excessive.
Be provided with dust cap 62 above described shell, the floating cover 61 for fixing dust cap is fixed on floating neutral block.
The lower end of described shell is provided with cover plate 63, and the outer ring of oscillating bearing fixed by shell and cover plate; Be provided with lamina tecti 64 and the dust cover 64 for the protection of oscillating bearing below cover plate, cover plate and lamina tecti clamp the edge, upper end of dust cover, and the lower end of dust cover then embeds in the groove of Lower shaft sleeve outer circumference surface.
Utility model works principle is as follows:
As shown in Figure 8, the utility model 90 is fixed on support 91, and the collet chuck being fixed on main shaft bottom holds grinding head, and after passing into Compressed Gas, grinding head followed by main shaft and together rotates, and 92, robot catches workpiece 93 to carry out reconditioning processing on grinding head; When the stressed deflection of grinding head, the axle sleeve upper end of swinging structure offsets, thus promotes to float accordingly to follow closely in return structure to exit installing hole along radial direction; Now inject gases at high pressure to force the reverse return of nail that floats by air admission hole, floating nail will promote axle sleeve and get back to vertical state from shift state, and grinding head also gets back to initial position, and robot continues to process workpiece.
