Free rotating and connecting device of hose bag

Abstract

The invention relates to a free rotating and connecting device (1) of a hose bag. The free rotating and connecting device (1) comprises a semicircular connecting piece (3) and a connecting piece (2) connected with the semicircular connecting piece (3), wherein the connecting piece (2) is provided with a semicircular end part (9) which corresponds to the semicircular connecting piece (3) so as to form a circular ring, a rod part (10) extending from the semicircular end part (9), and a connecting plate (8) connected at the tail end of the rod part (10); the free rotating and connecting device (1) further comprises a ball-shaped free rotating and connecting component (11); the ball-shaped free rotating and connecting component (11) comprises a ball-shaped cavity (17) connected at the connecting plate (8) and a rotating ball connecting rod (5) which is fixed by virtue of the ball-shaped cavity (17) and rotates; and the rotating ball connecting rod (5) is provided with a ball-shaped front end (12) limited in the ball-shaped cavity (17) and a rod body (14) extending out of an opening at the lower end of the ball-shaped cavity (17) from the ball-shaped front end (12). According to the free rotating and connecting device (1), the rotation degree of freedom in a robot and a control circuit is enhanced, the interference is reduced and the service life is prolonged.

Description

technical field [0001] The invention relates to a free-rotating connection device for a robot hose package, especially for the connection between an industrial robot and a control circuit. Background technique [0002] The existing robot hose package connection device is a straight rod type connection, see Figure 1a-1c , shows a hose pack straight rod connection device 1' in the prior art. Such as Figure 1a-1c As shown, the shape of the hose package straight rod type connection device 1' is like a racket structure, including a semicircle connection part 3', a long straight rod connection part 2' connected with the semicircle connection part 3', which has a The corresponding semicircular end 9' of the connecting piece 3' and the straight rod part 10' extending from the semicircular end 9', the semicircular end 9' and the semicircular connecting piece 3' through the bolt 4' connected to form a circular ring, and also includes a square connecting plate 8' connected with the ...

Problems solved by technology

[0004] However, the hose pack straight rod type connection device has the following problems: when the robot shaft rotates, this hose pack straight rod type connection device has no rotational freedom and is not flexible enough. At the same time, the rotation space between the robot and the hose pack is limited, which is easy Interference with the robot will cause double wear of the robot body and the hose package, shorten the life of the hose package, and generate greater noise. At the same time, because the straight line connection needs to be configured with a longer line to connect, it increases the cost of the entire device. cost
