Abstract

In a box frame mounted robot, the X axis member 10 is terminated in a joint housing 12 which moves along the Y-axis member 14. The joint 12 is an integral part of the X-axis arm 10 casting eliminating brackets, stops, etc. The joint 12 also provides a housing for the trolleys 16 and 18 that ride along the Y-axis member 14. The joint 12 walls also serve as "way wipers".

End of X-Axis Joint

In a box frame mounted robot, the X axis member 10 is terminated in a joint housing 12 which moves along the Y-axis member 14. The joint 12 is an integral part of the X-axis arm 10 casting eliminating brackets, stops, etc. The joint 12 also provides a housing for the trolleys 16 and 18 that ride along the Y-axis member 14. The joint 12 walls also serve as "way wipers".

The trolleys 16 and 18 are shown in position in Fig. 1. Trolley 16 rides on the top surface of the Y arm 14, and the bottom trolley 18 rides along the bottom surface of the Y arm. The upper trolley 16 is supported by an adjustable swivel pad socket setscrew 20 which permits the trolley to conform to dimensional variations in the guide rail or arm 14. The bottom trolley 18 is supported by a spring-loaded ball plunger 22 which functions like the swivel-pad socket setscrew trolley adjustment 20 for the upper trolley with the additional feature of spring support which permits flexibility for shock loads as well as allowing conformance to thickness variations in the guide rail or arm 14.

Fig. 2 is a cross-sectional view showing in more detail the operation and mounting of the upper and lower trolleys riding on the Y-axis member.
