Abstract:
The present invention relates to a method for manufacturing a joint. The method includes the following steps: A. mounting a pin on a ball, B. machining spherical surfaces on at least two socket parts, C. applying grinding paste on the ball and/or on the surfaces if the socket parts, D. connecting the pin to an equipment that rotates the ball, E. assembling the ball between the socket parts, F. applying a pressure between the socket parts and the ball, G. rotating and tilting the ball over the working range of the joint, H. cleaning the ball and the socket parts from the grinding paste, and I. assembling the joint by mounting the socket parts on a ball. The invention also relates to a joint obtainable with the method according to the invention.
Abstract:
The invention provides an industrial robot comprising a first robot part (38a) and a second robot part (4a) arranged to be moved in relation to each other, and at least one drive unit (1) arranged to move one of the robot parts (,) during operation of the robot.
