Description

VI. Description of the Invention: [Technical Field to Which the Invention Is Alonged] The present invention relates to a robot connecting shaft, which is connected to a person. [Prior Art] The industrial robot system can imitate a person's (four) function reading, grasping, transporting objects or operators, and the type of automatic device. Industrial robot

MM achieves the mechanization and automation of production, and can be used in mechanical systems such as electronics and atomic energy industries. With the constant technology, people gradually develop into multi-axis to achieve more complex movements. In the Xi axis robot, the phase-connected - axis + is relatively rotated, so the two-axis

In particular, it relates to a multi-axis machine that will be stored in a certain gap. When the robot is in a harsh environment, such as oil: or other environments with a lot of waste liquid, the joint faces of the two shafts are all flat, oil or other liquid may stick to the joint end face, when the two shafts rotate. It is easy to enter the robot from the joint and corrode it; the fittings affect the normal operation of the robot. SUMMARY OF THE INVENTION It is necessary to provide a robot connecting shaft that can prevent external liquid from entering the inside. A robot connecting shaft includes a first shaft body and a second shaft body rotatably coupled to the first shaft body, the first shaft body includes a base and a first interface away from the base, and the second shaft body has a docking with the first interface The second interface, the first interface is provided with a first chamfer, the second interface is provided with a second chamfer, the first chamfer 1362318 is the second inclined groove, and the inclined slot is connected to the robot. The 卩 is connected and faces the opening of the first shaft base. The other person connects the shaft to the interface of the first-axis body and the second shaft body respectively, and recognizes the chamfering and the second chamfering respectively, and the first chamfering and the tilting groove of the second person and the robot are connected to the outside of the shaft and The opening σ is toward the base of the first shaft ,, so oil or other liquid is not likely to accumulate at the joint of the first shaft body' to prevent the liquid from being in the first shaft body and the second shaft body; . Axis Rotation [Embodiment] Robot Connection The present invention will be further described in detail with reference to the accompanying drawings and embodiments. Please refer to the embodiment of the present invention. The robot connecting shaft 100 includes a first shaft body 10 and a second shaft body 30 rotatably coupled to the first shaft body 10. Referring to FIG. 2, the first shaft body 10 includes a base u and is extended from the base u.

The extended outer casing 13 is coupled to the first mounting portion 15 and to the retaining member 17 detachably coupled to the outer casing 13. The base 11 is substantially a rectangular plate, and mounting holes 111 are formed at four corners thereof. The outer casing 13 is a cylinder extending from the base u, and the outer casing 13 has a first interface 131, a first correcting portion 133, and an outlet port 135. The first interface m is circularly located at one end of the outer casing 13 away from the base u. The first interface 131 is provided with a first chamfer 1311, and the angle of the first chamfer 1311 can be between 3 degrees and 6 degrees. Any angle 'In the present embodiment, the inclination angle of the first chamfer 13 is 45 degrees, and the inner wall height of the outer casing 13 is larger than the outer wall. First School 5 • The front portion 133 is the first connection from the outer casing 13. (3) The rectangular block formed by the wall protrusion, the upper surface correcting hole 133 is provided: the first correcting portion 133 of the second opening is provided with a first position, which is available for _not shown), and the second casing is placed close to the base. The structure can be a matrix. It can be understood that the outer casing 13 may not be circular. Jing or other shapes 'only need the first-interface 131 square ^ - text = 15 from the base " the middle extension, and the extension of the outer casing 13. The same as the first ampoule portion 15 is located in the outer casing U. For mounting components such as a motor (not shown) and a speed reducer (not shown). The first housing portion 15 and the outer casing 13 have a certain space to accommodate the cable. = the position member 17 is known to be made of rubber' and is detachably fixed to the 乂, 133 by screws for easy replacement. Of course, the limiting member 丨7 can also be made of other buffering materials such as plastic. Read more in FIG. 3' The first shaft body 30 includes a joint 31 and a mount 33. The connecting base 31 includes a connection 311 extending from the edge of the connecting surface 311: a wall 313, a second mounting portion 315 extending from a middle portion of the connecting surface 311, and a plurality of reinforcing ribs interposed between the side wall 313 and the second mounting portion 315 317. The side J 313 has a second interface 3131 and a second correcting portion η]]. The second interface 3131 is circular, and is located at one end of the side wall 313 away from the connecting surface 3, and the second interface 3131 is provided with a second chamfer 3135. The second chamfer 3135 can be 3G to 6 degrees. In the present embodiment, the angle of inclination of the third chamfer 3135 is 45 degrees, and the outer surface of the side wall 313 is greater than the inner surface. The second correcting portion is formed to protrude from the outer surface of the side wall, and the second correcting hole 3137 is opened thereon. 1362318, the second dian 315 extends from the middle of the connecting surface 311, and the extension t direction is the same. The first mounting portion Γ5 of the first shaft 1110 is mounted in the second mounting jaw 315 and the first body 10 and the second shaft body 30 are rotatably coupled. The provision of the first shaft reinforcing rib 317 to the side wall 313 and the second mounting portion 3 enhances the strength of the second shaft body 3''. The lacking room ... the mounting seat _33 extends obliquely from the connecting seat 31 for the wire motor, minus

The elements are not shown in order to connect the second shaft body 30 with another shaft body (not shown). Referring to FIG. 2 to FIG. 4, after the first (fourth) 1G and the second shaft body 3G of the robot connecting shaft (10) of the embodiment of the present invention are installed, the second shaft body 30 can be rotated to make the second correcting hole 3137 and the first shaft body. The first correction hole U31 of 10 is coaxial, thereby determining the origin of rotation. The limiting member 17 can abut against the second correcting portion 3133 of the second shaft body 3 to limit the rotation angle of the second shaft body, thereby preventing the cable from being twisted due to excessive rotation. * After the first shaft body 10 and the second shaft body 30 are installed, the first interface 131 = the first interface 3131 is butted, the first chamfer 1311 and the second chamfer 3135 group. Forming an inclined groove 5〇 (shown in FIG. 1) opening toward the base u of the first shaft body 1′ can prevent the waste liquid from flowing into the robot connecting shaft 1 from the connection between the first interface 131 and the second interface 31. 〇 Internal. Further, since the liquid does not accumulate at the joint, the first shaft body 1〇 and the second shaft body 3〇 can be prevented from rotating relative to each other. The waste liquid flows into the robot connecting shaft due to the rotation. In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application in accordance with the law. However, the above description is only the preferred embodiment of the present invention, and the scope of the patent application is not limited thereto. Equivalent modifications or variations made by persons skilled in the art, in light of the spirit of the invention, are intended to be included within the scope of the following claims.
