Description

Technical Field

[0001] The present invention relates to a TC bearing performance comprehensive detection system and method, in particular to a TC bearing performance comprehensive detection system and method, belonging to the technical field of bearing detection. Background Art

[0002] TC bearings, also known as oil-sealed bearings, are important accessories for threaded electric drill tools used in oil exploration and drilling. They are mainly used to withstand the radial loads generated by the drive shaft of the electric drill tool during operation, ensuring the normal operation of the equipment and reducing energy consumption and maintenance costs. They can withstand harsh conditions under high temperature, high pressure and high speed, and ensure the sealing and stability of liquids or gases.

[0003] Therefore, it is necessary to test the TC bearings. Existing testing devices usually use stamping mode to test the stress of TC bearings. The impact force is relatively large and it is easy to cause direct damage. It is also well known that when TC bearings are in use, they will not be suddenly subjected to a large impact force, and it is difficult to guarantee the impact caused by local defects during impact testing. That is to say, if the TC bearings are directly impacted once, it is difficult to determine the local situation because local defects may cause insufficient stress as a whole. Another point is that stamping tests the TC bearings from the outside, and the inside of the TC bearings cannot be tested, so the accuracy of the test is greatly affected.

[0004] Therefore, it is urgent to improve the comprehensive detection system of TC bearing performance to solve the above problems. Summary of the invention

[0015] A method for using a TC bearing performance comprehensive detection system comprises the following steps: Step 1: Bearing installation: first, sleeve the TC bearing onto the internal stress detection device, and then start the first high-pressure air pump to inject gas into the internal stress airbag to fix the TC bearing. Step 2: Inner diameter stress detection. After the TC bearing is sleeved on the internal stress airbag, the first high-pressure air pump continuously inflates the internal stress airbag to squeeze the inside of the TC bearing to detect the pressure of the inner diameter of the TC bearing. By moving the position of the internal stress airbag inside the TC bearing, different positions of the TC bearing are detected. Step 3: External diameter stress detection: the TC bearing is pushed into the external stress detection device through the internal detection mechanism, and then the internal stress airbag is removed from the TC bearing after deflation, and the external stress airbag inside the external stress detection device is started to squeeze the TC bearing to detect the external stress of the TC bearing; Step 4: Torque detection, push the TC bearing onto the torsion airbag of the torque detection mechanism, then inflate the torsion airbag, push the TC bearing into the external stress detection device, fix the TC bearing through the external stress airbag, and then start the torque detection mechanism to drive the torsion airbag to rotate, so as to complete the torque detection of the TC bearing; Step 5: Corrosion test: push the salt spray cylinder into the TC bearing through the corrosion test telescopic rod, then use the atomizing pump to extract the brine inside the brine tank and atomize it, and then spray it onto the inner side of the TC bearing through the spray nozzle on the salt spray cylinder to perform corrosion test; Step 6: Cooling test: Heat the TC bearing through the heating strips on the heating strip grooves, and then cool it naturally. The cooling speed of the TC bearing is tested through the temperature change.

[0016] The present invention has at least the following beneficial effects: 1. The internal stress detection device and the external stress detection device can be used to detect internal stress, external stress, torque and corrosion resistance of TC bearings, which greatly improves the detection range and detection flexibility. At the same time, the internal stress detection and external stress detection can be used to detect different positions of TC bearings, thereby preventing local defects and greatly improving the detection accuracy.

[0017] 2. After the TC bearing is fixed inside the sleeve, start the second high-pressure air pump to rush gas into the external stress airbag through the first air pump connecting pipe. After the external stress airbag expands, the TC bearing is squeezed and fixed, and then the gas is continuously introduced to increase the pressure on the TC bearing to detect the external stress of the TC bearing. The TC bearing is moved inside the external stress detection device through the internal detection mechanism, so that different positions of the TC bearing can be detected, thereby improving the detection range and detection accuracy.

[0018] 3. A torsion airbag is fixedly arranged on the torsion shaft. Therefore, after air is filled into the interior of the flow channel, the gas enters into the torsion airbag through the second through hole on the torsion shaft, and expands the torsion airbag to squeeze and fix the TC bearing. Then, the TC bearing is pushed into the interior of the external stress detection device through the internal detection mechanism, but does not completely enter the interior of the external stress detection device. That is to say, one end of the TC bearing is fixed on the second through hole, and the other end is fixed inside the external stress detection device. The second high-pressure air pump is started to inflate the interior of the external stress airbag, and the upper side of the TC bearing is fixed after the external stress airbag is inflated and expanded. After fixation, the torsion motor is started to rotate the TC bearing to detect the torsion resistance of the TC bearing.

[0019] 4. The salt water inside the salt water tank is extracted by the atomizing pump, and then passed into the salt spray cylinder through the atomizing connecting pipe to achieve the purpose of corrosion resistance test of TC bearings. The salt spray can be evenly sprayed on the inside of the TC bearing through the spray nozzle on the salt spray cylinder to increase the contact area. The diameter of the salt spray cylinder is smaller than the inner diameter of the TC bearing to ensure sufficient entry of oxygen and the reaction rate as soon as possible. At the same time, a heating strip groove is opened on the outer side of the salt spray cylinder, and a heating strip is fixed inside the heating strip groove. After the heating strip is started, the salt spray can be heated. The higher the temperature, the faster the reaction rate, which further enhances the reaction rate and ensures the rapid progress of corrosion resistance test.

The scope of use is greatly improved. The internal stress detection device 1 includes an auxiliary limiting mechanism 4 and an internal detection mechanism 3 slidably arranged on the auxiliary limiting mechanism 4. The internal detection mechanism 3 includes an internal stress-propelled telescopic rod 301 and a connecting tube 302 arranged at the output end of the internal stress-propelled telescopic rod 301.

After the first high-pressure air pump 6 is started, gas is rushed into the interior of the connecting tube 302 through the second air pump connecting pipe 601. The gas enters through the first through hole 305 on the connecting tube 302 and then enters the interior of the internal stress airbag 304, so that the internal stress airbag 304 expands.
