Definitions

• the present invention relates to a bearing support structure for a robot wrist, and is used for an industrial robot.
• the inner ring side of the outer ring crack cross-linker bearing 119 is supported by the support 12 'of the iron shaft 12 and the metal.
• the support part 12 ′ and the support piece 15 are fixed to each other by bolts 18, and the support piece 15 is fixed to the revolving passive member.
• the outer support 110 made of rubber is sandwiched between the iron support pieces 14 and fixed with the bolts 17, and the fixing projections 110 ′ of the outer support 110 are bolted to the support base 11.
• the housing was fixed at 16 and the outer support 110 and the support base 11 constituted a housing.
• the bearing support structure shown in Fig. 4 is a suitable support structure for the robot's wrist, but the number of small parts is large, and the man-hours in assembly and maintenance are increased. . Disclosure of the invention
• the fixed side of the bearing that is, the outer ring side
• the plastic outer support 1 1 as shown in FIG. 1 by insert molding.
• the conventional problem has been solved or improved by burying and fixing the fixing projections 10 ′ of the outer support 10 to the support base 11 with bolts 16.
• the bearing can be handled as a single part integrated with the outer support, and the number of parts has been reduced, making assembly and maintenance of the wrist easier and easier.
• each part for supporting the outer side of the cross roller can be omitted, and the number of assembly steps associated with a reduction in the number of parts is reduced.
• the cost can be reduced and the cost can be reduced.
• the outer support 10 is a plastic that is lighter than conventional aluminum materials, the weight of the wrist of the mouth bot can be reduced.
• FIG. 1 is a schematic sectional view of the bearing support structure of the present invention.
• Fig. 2 is an overall schematic side view of a robot to which the present invention is applied
• Fig. 3 is a schematic front view of the same.
• FIG. 4 is a schematic cross-sectional view of a conventional bearing support structure. BEST MODE FOR CARRYING OUT THE INVENTION
• Fig. 1 is a schematic cross-sectional view of the bearing support structure embodying the present invention. As is evident from the figure, a steel inner ring crack Inject resin, and cross-hole-to-labeling An outer support 10 having a fixing projection 10 ′ on the outside was formed by being buried and integrated on the surface.
• FIGS. 2 and 3 are schematic views of the entire robot in which the present invention is implemented.
• the first arm 3 is connected to, the first arm 3 the upper end provided with a second arm 2 you U rotated up and down through a second joint J 2, the second arm 2 tip, wrist joint J 3
• a wrist part 1 that turns, turns, and turns through.
• a mounting portion 13 for fastening various operating pieces is fastened.
• the bearing is integral with the outer support 10, for example, as shown in FIG. 4, an iron holding piece 14 and an iron holding member for holding the bearing outer ring side are provided. Parts such as fastening bolts 17 between the piece and the outer support 110 can be omitted, the wrist can be easily assembled, the number of parts is small, and the outer support 10 is plastic molded. As a result, the weight of the wrist can be reduced.
