Detailed description of the invention
In order to there be understanding clearly to technical characteristic of the present invention, object and effect, now contrast accompanying drawing and the specific embodiment of the present invention is described.
Technology provided by the invention is to provide a kind of carrier 1, utilizes central gear and planetary relation, can the difficulty of efficient solution known technology.The workpiece of work piece is loaded into after on fixture, utilizes planetary gear to revolve round the sun and reaches the object that workpiece overturns simultaneously while rotation.
The schematic perspective view of carrier 1 as shown in Figure 1 and the plane relation schematic diagram of Fig. 2, comprise on a pedestal 2 and have a motor 44, motor output shaft 45 connects a driven wheel 40, one driven gear 35 driven by driven wheel 40, rotate centered by a fixed axis 5, one disk 30 is fixed on driven gear 35, one clutch shaft bearing 36 is socketed on driven gear 35 and between disk 30 and fixed axis 5, and make driven gear 35 and disk 30 with fixed axis 5 for friction during axis rotation is minimum, one central gear 10 is fixed on the fixed axis 5 of the suitable At The Height above disk 30, affixed mode is not limit, such as (or claim public with external screw teeth and internal screw thread, female thread) or weld or separately all can so that fixed head is affixed, multiple planetary gear 20, each with one second fixed axis 25 for axis rotation, one workpiece fixing seat 27 is fixed on the addendum circle of the end of planetary gear 20.Fig. 2 A shows the schematic top plan view of planetary gear 20 and central gear 10.
One second bearing 26 is socketed between planetary gear 20 and the second fixed axis 25, and makes planetary gear 20 with the second fixed axis 25 for friction during axis rotation is minimum.
Above-mentioned multiple planetary gear 20, with the axle center rotation of the second fixed axis 25, revolves round the sun simultaneously centered by central gear 10.Second fixed axis 25 is fixed on disk 30, and affixed mode is not limit, such as, with external screw teeth and internal screw thread (or claiming male and female thread) or welding or screw or nail is affixed all can.
Above-mentioned workpiece fixing seat 27 is fixed on the end of planetary gear 20, and therefore, as long as planetary gear 20 rotates, workpiece fixing seat 27 also can synchronous axial system together.Workpiece fixing seat 27 loads a workpiece 28.The mode that workpiece 28 is loaded into workpiece fixing seat 27 is not limit, and can be clamping, electromagnetic adsorption or vacuum suction.Certainly, with clamp or electromagnetic adsorption cost lower, and vacuum suction, though cost is relatively high, absorption affinity easily controls, and the loading or unloading time is also short, and clamping then needs to coordinate fixture (not shown).
Central gear 10 and planetary gear 20 have identical circular pitch (Circular pitch), and according to a preferred embodiment of the present invention, workpiece 28 is hexahedrons, and except one side is fixed on except workpiece fixing seat 27, all the other five faces are all processed.Selected central gear and the gear ratio of planetary gear 20 are 2:1, and planetary gear 20 is fixed on disk 30 by the second fixed axis 25 with a tiltangleθ.Planetary gear 20 itself with fixed axis 5 for revolving round the sun, with the second fixed axis 25 rotation in axle center.When planetary gear 20 revolve round the sun 1 week time, planetary gear 20 rotation 2 weeks, has namely only revolved round the sun 45 when planetary gear 20 often turns 90 °.The periphery of central gear 10 has eight planetary gears 20 (being all same track).In the embodiment shown in fig. 1, have eight planets, θ about 60 °.

Certainly, each machined surface of above-mentioned workpiece 28 on demand, area, processing content, and make some face need long processing time, some is then short, and even do not need processing, these changes above-mentioned can achieve the goal through the setting of Interprocess Controller 140.
In the present invention, eight planetary gears 20 that central gear 10 is hung, also can be considered eight stations, and therefore, above-mentioned front processing also can select one of them the station processing at rear four stations, or two station processing.Certainly, also can utilizing in the process at the 5th to the 8th station, carry out resistance measurement, or spray paint or sputter etc. or carry out the second stage processing of each side, allocating according to needing.
The present invention has following advantage:
1. workpiece is loaded once, and except bottom surface, other front and side can be processed, and unloading interval scale, after completion of processing.In middle turn-over process, workpiece does not need unloading.
2. carrier of the present invention is specially adapted to Laser Processing.Because the Laser Processing time is short, and machining tool does not need to be attached on workpiece.Therefore, such as there is the processing of similar characteristics, also can utilize carrier of the present invention.
3., compared to prior art, process with a collection of coplanar, then turn-over, workpiece loading of the present invention unloads interval scale again and completes, and therefore, the time of duration is more easily grasped.
4. prior art, processes to multiaspect simultaneously, and must have the processing laser of many groups, the present invention then only needs a set of processing laser 110.
