[0002] Thermocouples are commonly used temperature measuring elements in temperature measuring instruments.

[0033] Example 2

[0034] Based on the first embodiment, and different from the first embodiment,

[0035] A thermocouple sealing cap performance testing tool further comprising:

[0036] The material picking component 200 is used to pick up materials from the thermocouple sealing cap body 300. The material picking component 200 includes a hollow mounting seat 201 fixed on the upper surface of the base 100, and a rotating rod 202 rotatably set on the upper surface of the hollow mounting seat 201. The inner bottom wall of the hollow mounting seat 201 is provided with a second motor 2010 for driving the rotating rod 202 to rotate, and the output end of the second motor 2010 is fixed with an active gear disc 2011.

[0037] The bottom end of the rotating rod 202 extends into the interior of the hollow mounting seat 201 and is rotatably connected to the inner bottom wall of the hollow mounting seat 201 . A driven gear disc 2012 meshing with the driving gear disc 2011 is fixed to the surface of the rotating rod 202 .

[0038] The second motor 2010 is provided to facilitate adjustment of the position of the thermocouple sealing cap body 300 after adsorption and fixation, so that the thermocouple sealing cap body 300 can reach directly above the test assembly 400 .

[0039] A lifting rod 203 is slidably provided on the surface of the rotating rod 202 . A strip-shaped opening is opened on the surface of the rotating rod 202 , and the lifting rod 203 is slidably connected to the inner wall of the strip-shaped opening.

[0040] A third motor 2013 is fixed to the top of the rotating rod 202, and the output end of the third motor 2013 extends to the inner wall of the strip opening and is fixed with a threaded column 2014 that is rotatably connected to the inner bottom wall of the strip opening. A threaded hole is provided on the surface of the lifting rod 203 that is threadedly connected to the outer surface of the threaded column 2014. The setting of the third motor 2013 can realize the automatic lifting and lowering of the thermocouple sealing cap body 300 after adsorption and fixation.

[0041] A mounting plate 204 is fixed to the end of the lifting rod 203. A vacuum plate 205 is rotatably mounted on the lower surface of the mounting plate 204. A plurality of vacuum tubes 206 are embedded in a circular array on the lower surface of the vacuum plate 205. A vacuum suction cup 207 is mounted at the bottom end of each vacuum tube 206. A vacuum generator 208 for extracting and degassing the interior of the vacuum plate 205 is mounted on the side of the vacuum plate 205. A first motor 209 for driving the vacuum plate 205 to rotate is mounted on the upper surface of the mounting plate 204.

[0042] The output end of the first motor 209 extends to the lower surface of the mounting plate 204, and the bottom end of the output end of the first motor 209 is fixedly connected to the upper surface of the vacuum plate 205. The setting of the first motor 209 can realize the quick connection between the fixed thermocouple sealing cap body 300 and the connecting seat 402.

[0043] In this embodiment, by providing the material taking component 200, the tooling can achieve the purpose of automatically loading and taking materials for the thermocouple sealing cap body 300 during actual use, with a high degree of automation, which effectively improves work efficiency.

[0044] During operation, the threaded column 2014 can be rotated by the rotation of the third motor 2013. The rotation of the threaded column 2014 drives the lifting rod 203 to move downward, so that the vacuum suction cup 207 is adsorbed on the surface of the thermocouple sealing cap body 300. Then, the vacuum generator 208 is started to make the vacuum suction cup 207 effectively adsorb the surface of the thermocouple sealing cap body 300, and the third motor 2013 is started to reverse and drive the thermocouple sealing cap body 300 to rise. Then, the second motor 2010 is started to drive the active gear disc 2011 to rotate. The rotation of the active gear disc 2011 drives the driven gear disc 2012 and the rotating rod 202 to rotate, so that the thermocouple sealing cap body 300 follows the rotating rod 202 to rotate 180 degrees and reaches directly above the test assembly 400. The third motor 2013 is started again to drive the thermocouple sealing cap body 300 to move downward and correspond to the connecting seat 402. Then, the first motor 209 is started to drive the vacuum disc 205 and the thermocouple sealing cap body After the body 300 is rotated to make an effective connection with the connecting seat 402, the thermocouple sealing cap main body 300 is installed on the connecting seat 402, and the air pump 403 is started to inflate the interior of the thermocouple sealing cap main body 300. When the air pressure reaches a certain value, the inflation is stopped. At this time, the reading of the digital pressure gauge 405 is observed for 5 minutes to observe whether the reading of the digital pressure gauge 405 changes. If the value remains unchanged, it indicates that the sealing performance of the thermocouple sealing cap main body 300 is good. If the value decreases, it indicates that the sealing performance of the thermocouple sealing cap main body 300 is unqualified, thereby achieving the purpose of quickly testing the sealing performance of the thermocouple sealing cap main body 300, ensuring that the sealing performance of the thermocouple sealing cap main body 300 installed on the thermocouple is qualified, thereby ensuring the service life of the thermocouple, so that the tooling can achieve the purpose of automatically loading and taking out the thermocouple sealing cap main body 300, with a high degree of automation, effectively improving work efficiency.
