Embodiment
Fig. 1 shows centering of the present invention and orientation module.The top of supporting structure comprises mounting panel and cramp bar, and cramp bar passes a pair of polygonal panel and is connected, and can regulate with respect to bottom support panel.The a pair of screw that is inserted into the screwed hole that passes in the cramp bar leans against on the face up of bottom support panel sidewall.Motor (63) and bear box are attached on this supporting structure.
Fig. 2 shows the partial assembled of centering machine of the present invention.When cylinder (17) when stretching out, it applies power upwards to the holding screw (not shown) that is connected with bar (20).This bar (20) passes two interior slide bushings (21) of quill shaft (18) that are accommodated in centering body (22).Centering body (22) comprises finger-like supporting member (12) that is positioned at centering body (22) upper end and the hole that extends through the finger-like supporting member.Quill shaft (18) is attached in the bottom of centering body (22).Slide bushing (21) has reduced dynamic friction, is used to make bar (20) to shift reposefully.The upper end of bar (20) is anchored on spindle frame (23).Preferably, each of four arms (24) all is pivotally mounted in the curved elbow place between a pair of supporting member (12) of centering body (22).First end (24a) of each arm (24) is inserted in the chamber (26) of spindle frame (23).Second end (24b) of each arm (24) partly cooperates with the U-shaped that refers to support (27).These supports (27) are inserted in a plurality of grooves (28) that are arranged on the centering pedestal (29), and centering pedestal (29) is installed on the centering body (22).Refer to that (30) are attached to finger support (27) clamp to be provided and to hold needed surface.
Fig. 3 shows the cross-sectional view strength of centering machine.Compression spring (31) is positioned at centering body (22).When cylinder (17) stretched out and make bar (20) action, compression spring (31) was compressed.When eliminating the power that is applied by cylinder (17), compression spring (31) stretches and makes bar (20) turn back to its initial position downwards.
Fig. 4 is meant the schematic diagram of the moment of (30) withdrawal.When spindle frame (23) during owing to the moving up of bar (20), the inner surface of the lower flange (40) of spindle frame (23) promote to be positioned at spindle frame (23) chamber (26) the arm that is pivotally mounted (24) first end (24a) this part.When arm (24) pivoted, the power that makes progress that is applied made that arm (24) is the center rotation with pivotal point (42).This causes conversely with second end (24b) that refers to the arm (24) that support (27) cooperates apply power on the outer wall (43) of the U-shaped part that refers to support (27), thereby generation refers to (30) moving radially outwardly.
Fig. 5 shows the schematic diagram that refers to the moment stretch out.When spindle frame (23) during owing to the moving down of bar (20), the inner surface of the upper flange (50) of spindle frame (23) promote to be positioned at spindle frame (23) chamber (26) arm (24) first end (24a) this part.When arm (24) pivoted, applied force made that arm (24) is the center rotation with pivotal point (42).This causes conversely with second end (24b) that refers to the arm (24) that support (27) cooperates apply power on the inwall (51) of the U-shaped part that refers to support (27), thereby generation refers to (30) moving radially inwardly.
Fig. 6 is the schematic diagram of attitude reference device.The middle part of centering body (22) is connected in pulley (60), and this pulley (60) is connected to another pulley (62) that is driven by motor (63) by belt (61).Pulley (61, rotatablely moving 62) can cause in the centering machine (not to be shown in Fig. 6 except bar (20), but in front in the diagrammatic sketch clearly) and spindle frame (23) (in Fig. 6, do not show, but in front in the diagrammatic sketch clearly) outside other respective element rotate together, bar (20) and spindle frame (23) all have nothing to do with any rotatablely moving of centering body (22), and this is not to be positioned on the rotation of centering body (22) because the both is anchored on centering body (22).The chamber (26) of spindle frame (23) allows arm (24) (26) rotation along the chamber during rotation.The bear box (64) that has the bearing (not shown) also is connected on the centering body (22).
In second embodiment of the invention,, all similar except the structure of spindle frame (23) to first embodiment as being used to feel relieved and the structure of all parts of attitude reference device.The centering machine of second embodiment also comprises the centering body (22) with a plurality of supporting members (12) and quill shaft (18), described a plurality of supporting member (12) is positioned at the upper end of centering body (22), quill shaft (18) is positioned at the lower end of centering body (22), and bar (20) passes wherein.The spindle frame (23) of second embodiment forms, and flange (50) is provided with the translot (44) that is used to hold pedestal annex (41) thereon, as shown in Figure 7.Pedestal annex (41) has top board (42) and axle (43), and this axle (43) is assemblied in the spindle frame (23), and is attached in the centre of top board (42) in the upright position.Pedestal annex (41) can be elevated to predetermined height from spindle frame (23).
The upper end of bar (20) is fastened on the axle (43) of pedestal annex (41).Preferably, each in four arms (60) all is pivoted on the curved elbow place between a pair of supporting member (12) of centering body (22).First end (24a) of each arm (62) all is inserted in the chamber (26) of spindle frame (23).Second end (24b) of each arm (60) all is matched with the U-shaped part that refers to support (27).Centering refers to that (30) are connected to finger support (27) and go up clamp to be provided and to hold needed surface.
In this embodiment, second end (24b) of first pair of relative arm (60a) meshes with the inner surface of the top board (42) of pedestal annex (41).When pedestal annex (41) during owing to the moving up of bar (20), the inner surface of top board (42) raises, and reserves for this relative arm (60a) space that inherent curved elbow place pivots in the chamber (26) of spindle frame (23).When relative arm (60a) pivoted, the outside power of second arm (24b) can cause that the relative finger support (27a) that connects with second arm (24b) is from centering pedestal (29) moving radially outwardly, as shown in Figure 8.
When bar (20) when further moving up, can promote spindle frame (23) and move up, be pushed against another part in the chamber (26) that is positioned at spindle frame (23) up to the inner surface of the lower flange (40) of spindle frame (23) first end (24a) of relative arm (60b).Then, another can radially move from centering pedestal (29) outwardly to relative finger support (27b).
When bar (20) when moving down, can spur pedestal annex (41) and move down and make the inner surface (41) of top board (42) be pushed against the part of first end (24a) of the relative arm (60a) of the first couple in the chamber (26) that is positioned at spindle frame (23).When first pair of relative arm (60a) pivoted, applied force made that arm (60a) is the center rotation with pivotal point (42).This can cause that the relative finger support (27a) that connects with second arm (24b) radially moves from centering pedestal (29) inwardly, as shown in Figure 9.
When bar (20) when further moving down, can move down by pulling spindle frame (23), be pushed against the part of first end (24a) of the relative arm (60b) of the second couple in the chamber (26) that is positioned at spindle frame (23) up to the inner surface of the lower flange (40) of spindle frame (23).Then, another can radially move from centering pedestal (29) inwardly to relative finger support (27b).
According to this layout, when bar (20) when moving up, first pair of relative finger support (61a) radially moves at first outwardly, and when bar (20) can be radially mobile inwardly when moving down.Further moving up of bar (20) can radially move second pair of relative finger support (61b) outwardly subsequently, and further moving down of bar (20) can make second pair of relative finger support (61b) radially move inwardly subsequently.Chip is felt relieved and directed technical process in, when chip is not placed on holding portion of the present invention exactly, this will prevent the possibility that chip damages.
Though the preferred embodiment of the present invention and their advantage are open in above-mentioned detailed description, the present invention is not limited in content recited above, but is defined by the spirit and scope of the appended claims.
