[0032] Further, for the method of a robotic arm joint drag chain test device, the method steps are as follows:

[0033] S1: Jamming detection: Since the inner threaded plate is moving continuously, the corresponding air pressure will suddenly increase. The corresponding工字 block will generate a stronger driving force under the action of the air pressure. The工字 block will act on the first pressure sensor through the contact rod. The corresponding first pressure sensor will record the change of the force. Thus, the jamming situation of the drag chain can be detected and judged by observing the pause situation of the drag chain and the force change recorded by the first pressure sensor.

[0034] S2: Adjusting air holes: When the inclined surface T-shaped block two rises, it will contact the adjusting knob. The adjusting knob will send a command to the telescopic electric rod. The telescopic electric rod will drive the C-shaped closing plate to move towards the driving part. When the工字 circular block drives the drag chain to move to the maximum distance, the rectangular air outlet at the bottom of the corresponding C-shaped closing plate will communicate with the second through groove. At this time, the first through groove will leave the rectangular air outlet at the top of the driving part. At this time, the rectangular air outlet at the top of the driving part is in a closed state.

[0035] S3: Reciprocating closing air holes: Since the rectangular air outlet at the bottom of the C-shaped closing plate communicates with the second through groove, the air in the strip-shaped limiting box and the rectangular pipe will be discharged outside the driving part from the rectangular air outlet at the bottom of the C-shaped closing plate and the second through groove. Then, with the elastic force of the reciprocating spring, the工字 circular block will quickly reset. During the reset process, the smoothness of the drag chain is further detected. After activating the telescopic electric rod, the telescopic electric rod will drive the C-shaped closing plate to reset again after the inner threaded plate rises to the inner wall of the top of the driving part.

[0036] S4: Pressure detection: As the air pressure continues to increase, the movable plate will contact the工字 skateboard. The T-shaped round block will apply a force to the second pressure sensor. The second pressure sensor will drive the工字 circular block to descend. At this time, the telescopic spring will undergo compressive deformation. The工字 circular block will drive the drag chain to descend. The drag chain will deform under the action of the pressure. As the air pressure becomes larger and larger, the force applied by the corresponding工字 circular block to the drag chain will also be greater. Thus, the compressive resistance of the drag chain is detected, and the maximum bearing capacity of the drag chain is measured by the value on the second pressure sensor.

[0037] The present invention has the following beneficial effects:

[0038] (1) For a robotic arm joint drag chain test device of the present invention, during use, the head and the end of the drag chain are respectively placed into the U-shaped plates below the limit sliding blocks, and then the I-shaped circular screw rod 1 and the I-shaped circular screw rod 2 are rotated to fix the drag chain, improving the stability of detection. Then, the driving motor is started, and the driving motor drives the internally threaded plate to descend. The internally threaded plate will push the gas inside the driving part to descend and be compressed. The gas inside the driving part will enter the strip-shaped limit box through the rectangular pipe. As the air pressure increases, the gas will push the I-shaped block to move in the direction away from the driving motor. The I-shaped block will drive the contact rod to move. At this time, the limit spring will undergo compressive deformation. During the movement of the contact rod, it will contact the pressure sensor 1. After being subjected to the thrust, the pressure sensor 1 will drive the I-shaped limit block to move synchronously. Since the drag chain is fixed to the bottom of the I-shaped circular block by the I-shaped circular screw rod 1, when the I-shaped circular block moves, it will drive the drag chain to bend and move. Correspondingly, the reciprocating spring will undergo compressive deformation. Since the internally threaded plate descends at a constant speed, the air pressure is also in a stable state at this time. When the drag chain gets stuck, the I-shaped circular block will get stuck synchronously. However, due to the continuous movement of the internally threaded plate, the corresponding air pressure will suddenly increase. Correspondingly, the I-shaped block will generate a stronger driving force under the action of the air pressure. The I-shaped block will act on the pressure sensor 1 through the contact rod. Correspondingly, the pressure sensor 1 will record the change of the force, so that the stuck situation of the drag chain can be detected and judged by observing the pause situation of the drag chain and the force change recorded by the pressure sensor 1;

[0039] (2) For a robotic arm joint drag chain test device of the present invention, during the movement of the I-shaped circular block, it will drive the limit circular rod to move. The limit circular rod will drive the T-shaped circular block to move. The T-shaped circular block will drive the cylinder to move. The cylinder will drive the I-shaped sliding plate to slide. The I-shaped sliding plate will drive the mounting plate to move synchronously. The mounting plate will move on the inclined surface of the T-shaped block 1. The inclined surface of the T-shaped block 1 will contact the inclined surface of the T-shaped block 2 during the movement. Under the action of the inclined surface of the T-shaped block 2, the T-shaped block 2 will rise. At this time, the adaptation spring 2 will undergo compressive deformation. When the T-shaped block 2 rises, it will contact the adjustment button. The adjustment button will send a command to the telescopic electric rod. The telescopic electric rod will drive the U-shaped closing plate to move in the direction close to the driving part. When the I-shaped circular block drives the drag chain to move to the maximum distance, the rectangular air outlet at the bottom of the corresponding U-shaped closing plate will communicate with the through groove 2. At this time, the through groove 1 will leave the rectangular air outlet at the top of the driving part. At this time, the rectangular air outlet at the top of the driving part is in a closed state;

[0040] (3) In a drag chain test device for a robotic arm joint of the present invention, since the rectangular air outlet at the bottom of the U-shaped closing plate communicates with the second through groove, at this time, the air in the strip-shaped limiting box and the rectangular pipe will be discharged outside the driving part from the rectangular air outlet at the bottom of the U-shaped closing plate and the second through groove. Then, with the elastic force of the reciprocating spring, the工字 circular block will quickly reset. During the reset process, the smoothness of the drag chain is further detected. After activating the telescopic electric rod, the telescopic electric rod will drive the U-shaped closing plate to reset again after rising to the inner wall of the top of the driving part;

[0041] (4) In a drag chain test device for a robotic arm joint of the present invention, under the action of the reciprocating threaded rod, the inner threaded plate will rise. When the inner threaded plate rises, it will push air from the L-shaped round pipe, the first round sleeve, and the second round sleeve into the circular hollow plate again. The air will push the movable plate and the T-shaped round block to move in opposite directions. As the air pressure continuously increases, the movable plate will contact the工字 sliding plate, and the T-shaped round block will exert a force on the second pressure sensor. The second pressure sensor will drive the工字 circular block to descend. At this time, the telescopic spring will undergo compressive deformation, and the工字 circular block will drive the drag chain to descend. The drag chain will deform under the action of the pressure. As the air pressure becomes greater and greater, the corresponding force exerted by the工字 circular block on the drag chain will also be greater, thereby detecting the compressive resistance of the drag chain, and measuring the maximum bearing capacity of the drag chain through the value on the second pressure sensor.

[0042] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

The top end of the first adapting spring 318 is fixedly connected to the mounting plate 316, and the bottom end of the first adapting spring 318 is fixedly connected to the inclined surface T-shaped block one 317. A C-shaped frame 319 is fixedly installed on the top of the limiting part 3. A strip-shaped mounting plate 320 is fixedly installed on the C-shaped frame 319. An adjusting knob 321 is fixedly installed on the inner wall of the top of the C-shaped frame 319. An inclined surface T-shaped block two 322 is slidably installed through the strip-shaped mounting plate 320. A second adapting spring 323 is sleeved on the inclined surface T-shaped block two 322. The top end of the second adapting spring 323 is fixedly connected to the inclined surface T-shaped block two 322, and the bottom end of the second adapting spring 323 is fixedly connected to the strip-shaped mounting plate 320.

[0088] The cylinder 302 drives the I-shaped slide plate 301 to slide. The I-shaped slide plate 301 drives the mounting plate 316 to move synchronously. The mounting plate 316 moves on the inclined surface T-shaped block 1 317. The inclined surface T-shaped block 1 317 contacts the inclined surface T-shaped block 2 322 during the movement. Under the action of the inclined surface of the inclined surface T-shaped block 2 322, the inclined surface T-shaped block 2 322 rises. At this time, the adaptation spring 2 323 undergoes a compressive deformation. When the inclined surface T-shaped block 2 322 rises, it contacts the adjustment knob 321, and the adjustment knob 321 issues a command to the telescopic electric rod 311.

[0089] As Figure 1 - Figure 8 shown, a method for a manipulator joint drag chain test device is as follows:

[0090] S1: Jamming detection: Since the internal thread plate 203 is moving continuously, the corresponding air pressure will suddenly increase. The corresponding I-shaped block 206 will generate a stronger driving force under the action of the air pressure. The I-shaped block 206 acts on the pressure sensor 1 211 through the contact rod 210. The corresponding pressure sensor 1 211 records the change of the force. Thus, the jamming situation of the drag chain can be detected and judged by observing the pause situation of the drag chain and the force change recorded by the pressure sensor 1 211.

[0091] S2: Adjusting the air hole: When the inclined surface T-shaped block 2 322 rises, it contacts the adjustment knob 321. The adjustment knob 321 issues a command to the telescopic electric rod 311. The telescopic electric rod 311 drives the C-shaped closing plate 312 to move towards the direction close to the driving part 2. When the I-shaped circular block 212 drives the drag chain to move to the maximum distance, the rectangular air outlet 315 at the bottom of the corresponding C-shaped closing plate 312 communicates with the through groove 2 314. At this time, the through groove 1 313 leaves the rectangular air outlet 315 at the top of the driving part 2. At this time, the rectangular air outlet 315 at the top of the driving part 2 is in a closed state.

[0092] S3: Reciprocally closing the air hole: Since the rectangular air outlet 315 at the bottom of the C-shaped closing plate 312 communicates with the through groove 2 314, the air in the strip-shaped limiting box 205 and the rectangular pipe 204 will be discharged outside the driving part 2 from the rectangular air outlet 315 at the bottom of the C-shaped closing plate 312 and the through groove 2 314. With the elastic force of the reciprocating spring 2081, the I-shaped circular block 212 will quickly reset. During the reset process, the smoothness of the drag chain is further detected. After activating the telescopic electric rod 311, the telescopic electric rod 311 drives the C-shaped closing plate 312 to reset again after the internal thread plate 203 rises to the inner wall at the top of the driving part 2.

[0093] S4: Pressure detection: As the air pressure continues to increase, the movable plate 307 will contact the I-shaped slide plate 301, and the T-shaped round block 308 will apply force to the pressure sensor 309. The pressure sensor 309 will drive the I-shaped round block 212 to descend. At this time, the telescopic spring 213 is compressed and deformed, and the I-shaped round block 212 will drive the drag chain to descend. The drag chain will deform under the action of pressure. As the air pressure becomes higher and higher, the corresponding I-shaped round block 212 will apply greater force to the drag chain, thereby detecting the pressure resistance of the drag chain, and measuring the maximum pressure bearing capacity of the drag chain through the value on the pressure sensor 309.
