Single slideway sleeve barrel mechanical arm

Abstract

The present invention provides a single-slideway sleeved manipulator. The manipulator includes a single-bar slideway, the both sides of which are provided with grooves, an inner sleeve with raised keys is mounted on the single-bar slideway, an outer sleeve is mounted outside the inner sleeve, a gear ring is arranged on the lower end of the outer sleeve, the lower end of the inner sleeve is provided with a lug boss, on which a direct current servo motor is fixed, and a driving gear is mounted on the shaft of the direct current servo motor and engaged with the gear ring. A fixed pulley is fixedon the upper end of the single-bar slideway, a winding pulley mounted on the lower end is jointed with a servo winding motor via a coupling, both ends of a steel rope is fixed by two connecting boltsmounted on the inner sleeve, the steel rope is orderly connected with the fix pulley and the winding pulley via the grooves on both sides of the slideway, the inner sleeve is provided with a retainingscraper, a mechanical arm is firmly connected with the outer sleeve, and a paw is arranged on the end of the mechanical arm. The present invention has the advantages of compact structure, light weight, low energy consumption, long lifting travel and 360-degree rotation and can grasp and move any objects with irregular mesopores.

Description

(1) Technical field [0001] The invention relates to a manipulator, especially a manipulator capable of axial movement and circumferential movement. (2) Background technology [0002] In many workplaces, mechanical devices capable of moving, ascending, grabbing, lifting, loading, etc. are used. Therefore, there are many designs about manipulators at present. For example, the manipulator used in the robot competition can grab the middle-hole cylindrical volume block from the block storage area on the ground and send it to the block launching platform with a height of 1000mm. Because there is a large amount of lifting and rotation, the usual design method is to design a double-track slideway and an enveloping manipulator claw, and the whole is fixed to the main body of the robot with a gantry type to realize the rotation and lifting movement of the manipulator. The disadvantages of this kind of manipulator are: large volume, heavy weight, large rotation space, large moment of...

AI Technical Summary

Problems solved by technology

The disadvantages of this kind of manipulator are: large volume, heavy weight, large rotation space, large moment of inertia, low efficiency, difficult wiring, poor stability, etc.

Due to space constraints and working stroke requirements, the double-slider slider connection method is often used, but when there is a requirement for a circumferential degree of freedom stroke, the gantry type hoisting and fixing are often used, and these manipulators are bulky and redundant. , low control efficiency and other defects, ordinary double slideways need to rotate the entire slideway mechanism to achieve rotary motion, which consumes a lot of energy and noise, and is not suitable for precision operations in small spaces
