[0002] As the manufacturing industry becomes increasingly automated, the use of multi-joint robots is becoming increasingly common. Multi-joint robots perform various processing operations by replacing tools (such as welding heads and cutting tools). When replacing tools, the multi-joint robot releases the original tool to place it in the tool library, then locks the new tool and removes it from the library.

[0003] In existing technologies, when a multi-jointed robot is loosening or locking a tool, it must stop moving and wait for the tool to be changed before moving the tool to continue the operation. This can result in excessive tool changing time. Reducing this time is a question that those skilled in the art need to consider. Utility Model Content

The quick-change assembly 12 includes a connecting member 121 and a clamp member 125. The clamp member 125 is slidably arranged on the slide rail 112. The connecting member 121 includes a connecting ring 123 and a slider 124. The slider 124 is fixedly connected to the periphery of the connecting ring 123. The connecting ring 123 is detachably connected to the clamp member 125. The slider 124 can be moved along the slide rail 112 under force and abut against the push pin 113. The slider 124 rotates the connecting ring 123 to connect or separate the connecting ring 123 from the clamp member 125.

[0028] Please combine Figures 1 to 4 As shown, the quick-change device 1 provided in this embodiment moves the clamp member 125 into the slide rail 112 through the connecting member 121, and the sliding bracket 111 is used to place the clamp member 125. During the process of the connecting member 121 moving the clamp member 125 into the slide rail 112, the slider 124 and the push pin 113 push against each other, so that the slider 124 rotates the connecting ring 123 in a clockwise direction, thereby separating the connecting ring 123 from the clamp member 125; please refer to the embodiment of the quick-change device 1 Figure 5 and Figure 6 As shown, in the process of the connecting member 121 moving the clamp member 125 out of the slide rail 112, the slider 124 and the push pin 113 push against each other, so that the slider 124 rotates the connecting ring 123 counterclockwise, so that the connecting ring 123 is connected to the clamp member 125. Therefore, the quick-change device 1 locks or releases the clamp member 125 during the movement to reduce the time for changing tools.

[0029] In this embodiment, one end of the fixture 125 is connected to the connecting ring 123 , and the other end is connected to a processing tool such as a welding head or a cutting tool, so that the quick-change device 1 replaces the processing tool by locking or loosening the fixture 125 .

[0030] In one possible embodiment, the clamp member 125 includes a clamp body 126 and a connecting pin 127. The connecting pin 127 is fixed to one end of the clamp body 126 near the connecting ring 123. The connecting ring 123 is provided with a connecting hole 1231. The connecting hole 1231 includes a first through hole 1232 and a second through hole 1233. The first through hole 1232 and the second through hole 1233 are connected. The first through hole 1232 is used to rotate to a position corresponding to the connecting pin 127 to separate the connecting pin 127 from the connecting ring 123. The second through hole 1233 is used to rotate to a position corresponding to the connecting pin 127 to connect the connecting pin 127 to the connecting ring 123.

[0031] In this embodiment, the fixture body 126 is connected to a processing tool such as a welding head or a cutting tool, and the fixture body 126 is placed on the sliding bracket 111. When the processing tool needs to be installed, the connecting ring 123 is moved to a position close to the fixture member 125, and the first through hole 1232 of the connecting ring 123 is aligned with the connecting pin 127. The connecting pin 127 is inserted into the connecting ring 123 through the first through hole 1232. The connecting ring 123 is then rotated so that the connecting pin 127 is engaged with the second through hole 1233. This connects the fixture member 125 to the connecting member 121. The quick-change device 1 locks the processing tool during movement, thereby reducing the time required to change tools.

[0032] When the processing tool needs to be disassembled, the entrance of the sliding bracket 111 of the quick-change device 1 enters the slide rail 112, and the slider 124 moves along the slide rail 112 and abuts against the abutting pin 113, so that the slider 124 rotates the connecting ring 123 to make the connecting pin 127 enter the first through hole 1232 from the second through hole 1233, so that the clamp part 125 is separated from the connecting part 121. The quick-change device 1 separates the processing tool during the movement to reduce the time for changing tools.

[0033] In one possible embodiment, the connecting pin 127 includes a head 1271 and a rod 1272, one end of the rod 1272 is connected to the clamp body 126, and the other end is connected to the head 1271, the diameter of the head 1271 is larger than the diameter of the second through hole 1233 and smaller than the diameter of the first through hole 1232, and the rod 1272 cooperates with the first through hole 1232 to enable the head 1271 to be clamped with the connecting ring 123.

[0034] In this embodiment, the head 1271 passes through the first through hole 1232 and is inserted into the connecting ring 123, and then the connecting ring 123 is rotated so that the rod 1272 is stuck in the second through hole 1233, and the head 1271 corresponds to the periphery of the second through hole 1233, so that the connecting ring 123 is connected to the clamp body 126, and the clamp part 125 is connected to the connecting part 121. The quick-change device 1 locks the processing tool during the movement to reduce the time for changing tools.

[0035] In a possible embodiment, there are multiple connecting pins 127 , which are spaced apart from each other. There are multiple connecting holes 1231 , which are spaced apart from each other. The connecting pins 127 correspond to the connecting holes 1231 one by one.

[0036] In this embodiment, the quick-change device 1 is provided with multiple connecting pins 127, and the multiple connecting pins 127 rotate simultaneously to enter the second through hole 1233, so that the connection between the connecting ring 123 and the clamp body 126 is more stable, and the quick-change device 1 is quickly connected or separated from the processing tool to reduce the time for changing tools.

[0037] In a possible embodiment, a positioning hole 1261 is provided on the circumference of the clamp body 126 , and the slide rail 112 is movably provided with a pin 114 , which corresponds to the positioning hole 1261 , and is used to fix the clamp part 125 after the connecting ring 123 is separated from the clamp part 125 .

[0038] In this embodiment, when the clamp part 125 is separated from the connecting part 121, the clamp part 125 is placed on the sliding bracket 111 and connected to the clamp body 126 through the pin 114 to fix the clamp part 125. This setting is beneficial to improving the positioning accuracy of the clamp part 125 and facilitating the connecting part 121 to clamp the clamp part 125, thereby reducing the time for changing tools.

[0039] In a possible embodiment, the connecting member 121 further includes a connecting body 122 , which is disposed on a side of the connecting ring 123 away from the clamp 125 , and is fixedly connected to the connecting ring 123 , and is used to connect the robotic arm of the multi-joint robot.

[0040] In this embodiment, one end of the connecting ring 123 is fixedly connected to the connecting body 122 and the other end is detachably connected to the clamp part 125. The connecting body 122 is used to connect the robotic arm of the multi-joint robot. The multi-joint robot locks or releases the clamp part 125 during the process of moving the connecting part 121, thereby reducing the time that the multi-joint robot stops moving and reducing the time for changing tools.

[0041] In a possible implementation, the slider 124 is provided with an inclined surface 1241 , which corresponds to the abutting pin 113 . When the inclined surface 1241 contacts the abutting pin 113 , it drives the slider 124 to rotate the connecting ring 123 .

[0042] In this embodiment, as the connecting member 121 moves along the slide rail 112, the inclined surface 1241 of the slider 124 contacts the abutting pin 113, causing the abutting pin 113 to abut the inclined surface 1241 of the slider 124, causing the slider 124 to rotate. When the connecting member 121 enters the sliding bracket 111 along the slide rail 112, the slider 124 drives the connecting ring 123 to rotate clockwise, causing the connecting pin 127 to enter the first through-hole 1232 from the second through-hole 1233, thereby separating the clamp 125 from the connecting member 121. When the connecting member 121 moves out of the sliding bracket 111 along the slide rail 112, the slider 124 drives the connecting ring 123 to rotate counterclockwise, causing the connecting pin 127 to enter the second through-hole 1233 from the first through-hole 1232, thereby connecting the clamp 125 to the connecting member 121. This allows the quick-change device 1 to quickly connect or disconnect with the processing tool, thereby reducing the time required for tool replacement.

[0043] In a possible embodiment, the sliding bracket 111 further includes a stopper 115 , which is spaced apart from the push pin 113 , and is fixedly connected to the slide rail 112 . The stopper 115 corresponds to the slider 124 , and when the stopper 115 contacts the slider 124 , it pushes the slider 124 to rotate.

[0044] In this embodiment, the connecting member 121 enters the sliding bracket 111 along the slide rail 112, and the stopper 115 contacts and abuts the slider 124, causing the slider 124 to rotate clockwise, causing the connecting pin 127 to enter the first through-hole 1232 from the second through-hole 1233, thereby separating the clamping member 125 from the connecting member 121. The stopper 115 and the abutting pin 113 together abut the slider 124, allowing the slider 124 to drive the connecting ring 123 to rotate. This facilitates the smooth rotation of the connecting ring 123, facilitates the release of the clamping member 125 from the connecting member 121, and reduces the time required for tool replacement.

[0045] In summary, the quick-change device 1 provided in this embodiment moves the clamp part 125 into the slide rail 112 through the connecting part 121, and the sliding bracket 111 is used to place the clamp part 125. In the process of the connecting part 121 moving the clamp part 125 into the slide rail 112, the slider 124 and the push pin 113 push against each other, so that the slider 124 rotates the connecting ring 123 in a clockwise direction, thereby separating the connecting ring 123 from the clamp part 125; in the process of the connecting part 121 moving the clamp part 125 out of the slide rail 112, the slider 124 and the push pin 113 push against each other, so that the slider 124 rotates the connecting ring 123 counterclockwise, thereby connecting the connecting ring 123 to the clamp part 125. The quick-change device 1 can quickly lock or release the clamp part 125 during the movement, thereby improving the convenience of the quick-change device 1, reducing the labor intensity of manually replacing processing tools, and reducing the tool replacement time.
