Robot Arm with Adjustable Structure

Abstract

The invention provides a manipulator with an adjusting structure. The manipulator comprises a moving base which has a plurality of degrees of freedom of operation, and an adjusting module of which one end is chained with the moving base, wherein the adjusting module comprises a main body, a sleeve, a fixing part and combining means; the main body extends in a direction to form an elongated structure, and the extending direction is defined to be an axis direction; outer threads and an axial groove are formed in the outer edge surface of the main body; the sleeve is provided with a through hole sleeved with the outer threads; a bulge corresponding to the groove is arranged on the inner edge surface of the through hole; the bulge is stored into the groove to limit the degree of freedom of the sleeve rotating relative to the main body; the fixing part is provided with a through hole of which the inner edge surface is provided with inner threads, and the inner threads are screwed to the outer threads in the main body; the fixing part is fixed on one end surface of the sleeve through the combining means.

Description

technical field [0001] The invention relates to a robot, in particular to a robot arm with an adjustable arm length and an adjustable structure. Background technique [0002] Due to the manipulability of the robotic arm, it is widely used in equipment in various fields. For example, in the field of mechanical processing, the robotic arm can be used with a processing machine to automatically pick and place the processing object, allowing the processing machine to process the processing object; and in the medical field, the robotic arm can be controlled by a doctor. It can be used to perform surgery and medical treatment on patients; and then applied to the field of game entertainment, by controlling the movement of the mechanical arm to perform the function of clamping game objects. [0003] refer to Figure 9 As shown, the side view of the mechanical arm showing the first arm length is mainly composed of a pivotable base 11, a first arm unit 12 pivotally arranged on the bas...

Problems solved by technology

[0004] However, because the length of the support rod 132 in the second support arm unit 13 is fixed and cannot be adjusted, the mechanical arm can only be used for the control of a single distance. Another robotic arm with an arm length such as Figure 10 As shown, the length of the pole 152 of the second arm unit 15 is longer than Figure 9 The length of the pole 132 of the second arm unit 13 is suitable for the control of a long distance. Therefore, the mechanical arm of each specification can only be used for the control of a single distance, which highlights the defect of insufficient applicability.
