Embodiment Construction

[0019] The following examples refer to Figure 1~6 .

[0020] The omni-directional chassis of the industrial robot with variable wheelbase and capable of overcoming obstacles includes an industrial robot installation base 1, a casing 2, an ultrasonic sensor 3, a vehicle frame 4, a leg bracket 5, an electric push rod 6, a steering gear 7, and a steering gear connecting rod 8 , Servo motor 9, reducer 10, flange 11, Mecanum wheel 12, pen push rod 13, hinge 14, coaxial bracket 15, motor bracket 16, slide rail 17 and slider 18.

[0021] The industrial robot installation base 1 is installed on the frame 4. The frame 4 is an aluminum profile connection structure, which is constructed by the national standard 2020 industrial aluminum profile and supporting connecting corner fittings. It is the main part of the chassis and carries the entire weight of the chassis itself and the load. . Around the vehicle frame 4 and the top installation shell 2.

[0022] Four supporting legs are ins...

Abstract

The invention discloses a variable-wheelbase obstacle-surmounting omnidirectional chassis of an industrial robot, and is used to solve the technical problem that the existing omnidirectional chassis of an industrial robot is poor in obstacle-surmounting ability. The technical scheme adopted by the invention lies in that the front and rear wheelbase of the omnidirectional chassis can be changed. In addition, support legs are respectively mounted at four corners of the chassis. When not used, the support legs can be folded to reduce the occupied space; and when used, the support legs can be unfolded. After the support legs are unfolded, the support legs can extend downward to lift the whole chassis off the ground. When encountering obstacles, the support legs are unfolded to surmount the obstacles, and then lift the whole chassis off the ground; at this time, the wheelbase is changed, so that the wheels can surmount the obstacles; and after the obstacles are surmounted, the support legs are folded, and the chassis falls back to the ground to continue to move. For this reason, through the adoption of the variable-wheelbase obstacle-surmounting omnidirectional chassis disclosed by the invention, the obstacle-surmounting function of the omnidirectional chassis of the industrial robot is realized.

Description

technical field [0001] The invention relates to an omnidirectional chassis of an industrial robot, in particular to an omnidirectional chassis of an industrial robot with variable wheelbase and capable of surmounting obstacles. Background technique [0002] The modernization process of many industrial fields such as aerospace manufacturing, shipbuilding, petrochemical industry, etc. is accelerating, and strong technical strength and efficient productivity have become the core competitiveness of enterprises. In warehouses, airports, production workshops and other occasions, a large number of industrial robots are used to replace manual operations. However, most of the current industrial robots use a fixed-station working method, which is poor in versatility and flexibility. Due to the limitations of the work site and the large size and irregular shape of the industrial robot itself, it is difficult for ordinary mobile chassis to move it, and it is even more difficult to meet...
