[0019] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0020] Please see Figure 1-3This utility model provides a technical solution: an automatic sleeve changing device for robots, including a mounting plate 1 and a diameter changing mechanism 7. A robotic arm body 3 is arranged above the mounting plate 1, and a connecting housing 6 is arranged above the mounting plate 1. Multiple sets of arc-shaped blocks 8 are arranged on the outer side of the connecting housing 6. The diameter changing mechanism 7 is arranged on the connecting housing 6 and is used to fix the sleeve.

[0021] The diameter-changing mechanism 7 includes a micro motor 701, a rotating plate 702, a sliding bar 703, a mounting bar 704, and a fixing block 705. The micro motor 701 is fixedly installed on the top of the connecting housing 6. The output shaft of the micro motor 701 extends into the interior of the connecting housing 6 and is fixedly installed on the rotating plate 702. The rotating plate 702 has six sets of arc-shaped openings. A set of sliding bars 703 is slidably installed in each of the six sets of arc-shaped openings. A set of mounting bars 704 is fixedly installed on the outer wall of each of the six sets of sliding bars 703. One end of each set of mounting bars 704 extends to the outer side of the connecting housing 6 and is fixedly installed on the fixing block 705. The robotic arm body 3 drives the connecting housing 6 into the sleeve that needs to be replaced. The diameter-changing mechanism 7 can drive the arc-shaped block 8 to expand and contact the inner wall of the sleeve to fix and clamp the sleeve. Compared with the connection between the sleeve and the thread, it reduces the wear of the thread of the connecting part of the sleeve and prevents the sleeve from shaking and the parts from being unable to be tightened during assembly when the thread of the connecting part is worn, thus reducing the work efficiency of assembling parts.

[0022] Each of the six sets of fixing blocks 705 is fixedly installed on one side with a set of arc-shaped blocks 8, and the mounting rod 704 is slidably installed with the connecting housing 6.

[0023] A protective housing 5 is fixedly installed on the top of the connecting housing 6, and the micro motor 701 is located inside the protective housing 5.

[0024] The top of the mounting plate 1 is fixedly mounted with a robotic arm base 2, and the top of the robotic arm base 2 is rotatably mounted with a robotic arm body 3. One end of the robotic arm body 3 is fixedly connected to a connecting rod 4, and one end of the connecting rod 4 is fixedly mounted to a protective shell 5.

[0025] A motor 9 is fixedly installed at the bottom of the mounting plate 1. The output end of the motor 9 extends to the top of the mounting plate 1 and a rotating short rod 10 is fixedly installed thereon. A placement plate 11 is fixedly installed at the top of the rotating short rod 10. A circular groove for placing a sleeve is opened in the placement plate 11. Four sets of supports are fixedly installed at the bottom of the mounting plate 1.

[0026] Working principle: When a sleeve needs to be retrieved, the start motor 9 is controlled. The output shaft of the start motor 9 rotates, driving the rotating short rod 10 to rotate. The rotation of the rotating short rod 10 drives the placement plate 11 to rotate, which in turn drives the sleeve on the placement plate 11 to rotate. The sleeve to be replaced is rotated to the underside of the connecting housing 6. The robotic arm base 2 is started, driving the connecting housing 6 downwards into the sleeve. The micro motor 701 is started, and the output shaft of the micro motor 701 rotates, driving the rotating plate 702 to rotate. The rotating plate 702 drives the six sets of sliding rods 703 to slide in the arc groove, thereby driving the mounting rod 704 to extend to the outside of the connecting housing 6, and then driving the arc block 8 to move outwards. When the arc block 8 contacts the inner wall of the sleeve, the sleeve can be fixed. The robotic arm body 3 is controlled again to move the sleeve and perform assembly work. When a sleeve needs to be replaced, the robotic arm body 3 is controlled to put the sleeve back in its original position. The start motor 9 is controlled to rotate, bringing the sleeve to be replaced to the underside of the connecting housing 6, and the robotic arm body 3 takes it out.

[0027] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
