Description

Technical Field

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

[0002] The TC bearing, also known as an oil seal bearing, is an important accessory for the screw electric drill used in oil exploration drilling. It is mainly used to bear the radial load generated by the drive shaft of the electric drill tool during operation, ensure the normal operation of the equipment, reduce energy consumption and maintenance costs, and can withstand the harsh conditions under high temperature, high pressure and high speed environments, and ensure the sealing and stability of liquids or gases.

[0003] Therefore, it is necessary to detect the TC bearing. The existing detection devices usually use a stamping mode to detect the stress of the TC bearing, with a relatively large impact force, which is very easy to directly cause damage. As is well known, when the TC bearing is in use, it will not suddenly receive a large impact force, and it is difficult to ensure the influence caused by local defects during impact detection. That is to say, if a one-time impact is directly applied to the TC bearing, due to local defects, the overall stress may be insufficient, making it difficult to judge the local situation. Another point is that stamping detects the TC bearing from the outside, and it is impossible to detect the inside of the TC bearing, so the detection accuracy is greatly affected.

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

[0005] The purpose of the present invention is to provide a comprehensive detection system and method for the performance of a TC bearing.

[0018] A usage method of a comprehensive performance detection system for TC bearings includes the following steps:

[0019] Step 1: Bearing installation. First, the TC bearing is sleeved on the internal stress detection device, and then gas is introduced into the internal stress airbag by starting the first high-pressure air pump to fixedly install the TC bearing.

[0020] 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 inside of 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.

[0021] Step 3: Outer diameter stress detection. The TC bearing is pushed into the external stress detection device by the inner detection mechanism, then the internal stress airbag is withdrawn 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.

[0022] Step 4: Torque detection. The TC bearing is pushed onto the torsion airbag of the torque detection mechanism, then the inside of the torsion airbag is inflated, and the TC bearing is pushed into the external stress detection device. The TC bearing is fixed by the external stress airbag, and then the torque detection mechanism is started to drive the torsion airbag to rotate to complete the torque detection of the TC bearing.

[0023] Step Five: Corrosion resistance detection. Push the salt spray cylinder into the interior of the TC bearing through the corrosion resistance detection telescopic rod. Then, extract the brine inside the brine tank through the atomizing pump and atomize it. Then, spray it onto the inner side of the TC bearing through the spray nozzle on the salt spray cylinder for corrosion experiments.

[0024] Step Six: Cooling detection. Heat the TC bearing through the heating element on the heating element groove, and then let it cool naturally. Detect the cooling rate of the TC bearing through the change in temperature.

[0025] The present invention has at least the following beneficial effects:

[0026] 1. The internal stress detection device and the external stress detection device can perform internal stress detection, external stress detection, torque detection, and corrosion resistance detection on the TC bearing, greatly improving the detection range and flexibility. At the same time, through internal stress detection and external stress detection, different positions of the TC bearing can be detected, so the occurrence of local defects can be eliminated, and the detection accuracy can be greatly improved.

[0027] 2. After the TC bearing is fixed inside the sleeve, start the second high-pressure air pump to inflate the inside of the external stress airbag through the first air pump connecting pipe. After the external stress airbag expands, it squeezes and fixes the TC bearing. Then, keep inflating the gas to increase the pressure on the TC bearing to achieve the detection of the external stress of the TC bearing. By moving the TC bearing inside the external stress detection device through the internal detection mechanism, different positions of the TC bearing can be detected, improving the detection range and detection accuracy.

[0028] 3. A torsion airbag is fixedly arranged on the torsion shaft. Therefore, after filling the air into the flow channel, the gas enters the interior of the torsion airbag through the second through hole on the torsion shaft, and the torsion airbag expands to squeeze and fix the TC bearing. Then, push the TC bearing into the interior of the external stress detection device through the internal detection mechanism, but not completely into 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. After starting the second high-pressure air pump to inflate the inside of the external stress airbag, the external stress airbag inflates and expands to fix the upper side of the TC bearing. After fixation, start the torsion motor to rotate the TC bearing to detect the anti-torsion ability of the TC bearing.

[0029] 4. The brine inside the brine tank is pumped by an atomizing pump and then passed through an atomizing connecting pipe into the inside of the salt spray cylinder to achieve the purpose of corrosion resistance detection of the TC bearing. The salt spray can be evenly sprayed inside the TC bearing through the spray nozzles on the salt spray cylinder, increasing the contact area. Moreover, the diameter of the salt spray cylinder is smaller than the inner diameter of the TC bearing, ensuring the full entry of oxygen and accelerating the reaction rate. At the same time, a heating strip groove is provided on the outer side of the salt spray cylinder, and a heating strip is fixedly arranged inside the heating strip groove. After the heating strip is started, the salt spray can be heated, and the higher the temperature, the faster the reaction rate, further enhancing the reaction rate and ensuring the rapid progress of the corrosion resistance detection.

[0030] 5. A heating strip is fixedly arranged inside the heating strip groove, which can heat the TC bearing. After heating the TC bearing, it is then naturally cooled, and observing the temperature change is convenient for cooling detection of the TC bearing. Description of the Drawings

Detailed implementation mode

[0042] The following will cooperate with the drawings and embodiments to detail the implementation mode of the present application, so as to fully understand how the present application uses technical means to solve technical problems and achieve the implementation process of technical effects and implement accordingly.

[0043] As Figures 1-9 shown, the TC bearing performance comprehensive detection system provided in this embodiment includes an internal stress detection device 1 and an external stress detection device 2. The internal stress detection device 1 detects the inner side of the TC bearing, and the external stress detection device 2 detects the outer side of the TC bearing, greatly improving the scope of use. 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 pushing telescopic rod 301 and a connecting cylinder 302 arranged at the output end of the internal stress pushing telescopic rod 301. A connecting shaft 303 is fixedly connected to the connecting cylinder 302, and an internal stress airbag 304 is fixedly arranged on the connecting shaft 303. The internal stress airbag 304 is communicated with the inside of the connecting cylinder 302 through a first through hole 305. The bottom of the connecting cylinder 302 is connected to a first high-pressure air pump 6 through a second air pump connecting pipe 601. After starting the first high-pressure air pump 6, gas is introduced into the inside of the connecting cylinder 302 through the second air pump connecting pipe 601. The gas enters the inside of the internal stress airbag 304 through the first through hole 305 on the connecting cylinder 302, causing the internal stress airbag 304 to expand. After the internal stress airbag 304 expands, it squeezes the TC bearing to achieve the purpose of fixing the TC bearing;

[0044] Internal stress detection. A TC bearing is sleeved on the internal stress airbag 304. After the internal stress airbag 304 expands, the internal stress airbag 304 squeezes the inner side of the TC bearing. Then, the internal stress airbag 304 is continuously inflated to increase the pressure on the internal stress airbag 304, so as to achieve the purpose of detecting the internal stress of the TC bearing. At the same time, by moving the position of the internal stress airbag 304 inside the TC bearing, different positions of the TC bearing can be detected. Therefore, the occurrence of local defects can be eliminated, and the detection accuracy can be greatly improved;

[0045] External stress detection. The external stress detection device 2 includes an external stress pushing telescopic rod 201 and a sleeve 202 arranged at the output end of the external stress pushing telescopic rod 201. An external stress airbag 203 is fixedly arranged inside the sleeve 202. A fixed connection block 204 is fixedly arranged on the outer side of the sleeve 202. The external stress pushing telescopic rod 201 is fixedly connected to the fixed connection block 204. An external stress airbag 203 is fixedly arranged inside the sleeve 202. The TC bearing is fixed by the external stress airbag 203. The external stress airbag 203 is connected to a second high-pressure air pump 206 through a first air pump connecting pipe 205. After the external stress airbag 203 is inflated, the external stress airbag 203 is used to squeeze the outer side of the TC bearing. After the TC bearing is fixed inside the sleeve 202, the second high-pressure air pump 206 is started to inject gas into the internal of the external stress airbag 203 through the first air pump connecting pipe 205. After the external stress airbag 203 expands, it squeezes and fixes the TC bearing. Then, the gas is continuously introduced to increase the pressure on the TC bearing, so as to achieve the detection of the external stress of the TC bearing;

[0046] By moving the TC bearing inside the external stress detection device 2 through the internal detection mechanism 3, different positions of the TC bearing can be detected, and the detection range and detection accuracy can be improved;

[0047] Torque detection, as Figure 1 shown, a torque detection mechanism 5 is fixedly arranged on the outer side of the connecting shaft 303. The torque detection mechanism 5 includes a torsion motor 501 and a torsion shaft 502. A flow channel 306 is opened inside the rotor of the torsion motor 501. The flow channel 306 is communicated with the inside of the connecting cylinder 302. The torsion motor 501 is fixedly arranged on the connecting shaft 303. A flow channel 306 communicated with the inside of the connecting cylinder 302 is opened inside the connecting shaft 303. Therefore, the gas inside the connecting cylinder 302 can directly enter the internal of the first air pump connecting pipe 205 through the flow channel 306, and direct inflation is achieved through the connection of the flow channel 306. The structure is simple, which neither affects the normal rotation of the torsion shaft 502 nor affects the air delivery, and the use range and flexibility are improved;

[0048] The interior of the torsion shaft 502 is connected to the interior of the connecting cylinder 302 through the flow channel 306. A torsion airbag 503 is fixedly arranged on the torsion shaft 502. The torsion airbag 503 is connected to the interior of the torsion shaft 502 through the second through hole 504. Since the torsion airbag 503 is fixedly arranged on the torsion shaft 502, after air is filled into the interior of the flow channel 306, the gas enters the interior of the torsion airbag 503 through the second through hole 504 on the torsion shaft 502, and the torsion airbag 503 expands to squeeze and fix the TC bearing. Then, the TC bearing is pushed into the interior of the external stress detection device 2 by the internal detection mechanism 3, but does not completely enter the interior of the external stress detection device 2. That is to say, one end of the TC bearing is fixed on the second through hole 504, and the other end is fixed inside the external stress detection device 2. When the second high-pressure air pump 206 is started to inflate the interior of the external stress airbag 203, after the external stress airbag 203 is inflated and expanded, it fixes the upper side of the TC bearing;

[0049] After fixation, by starting the torsion motor 501, the TC bearing rotates to detect the torsional resistance of the TC bearing.

[0050] Furthermore, the device can also perform corrosion resistance detection, such as Figure 2 and Figure 8 As shown, a corrosion resistance detection mechanism 7 is arranged inside the sleeve 202. The corrosion resistance detection mechanism 7 includes a corrosion resistance detection telescopic rod 701 and a salt spray cylinder 703 arranged at the output end of the corrosion resistance detection telescopic rod 701. The salt spray cylinder 703 is inserted into the interior of the TC bearing through the corrosion resistance detection telescopic rod 701. A hollow driving rod 702 is arranged at the output end of the corrosion resistance detection telescopic rod 701. The hollow driving rod 702 is fixedly connected to the salt spray cylinder 703, and the interior of the hollow driving rod 702 is connected to the interior of the salt spray cylinder 703. Moreover, the hollow driving rod 702 at the output end of the corrosion resistance detection telescopic rod 701 is of a hollow structure. Therefore, the atomized salt spray can be directly discharged to the inner side surface of the TC bearing through the salt spray cylinder 703. A plurality of uniformly distributed spray nozzles 706 are arranged on the salt spray cylinder 703. The hollow driving rod 702 is connected to an atomizing pump 708 through an atomizing connecting pipe 707. A brine tank 11 is arranged directly below the corrosion resistance detection mechanism 7. The atomizing pump 708 is arranged inside the brine tank 11. The atomizing pump 708 extracts the brine inside the brine tank 11, and then passes it through the atomizing connecting pipe 707 into the interior of the salt spray cylinder 703 to achieve the purpose of detecting the corrosion resistance of the TC bearing. The salt spray can be evenly sprayed inside the TC bearing through the spray nozzles 706 on the salt spray cylinder 703 to increase the contact area. Moreover, the diameter of the salt spray cylinder 703 is smaller than the inner diameter of the TC bearing to ensure the full entry of oxygen and accelerate the reaction rate;

[0051] Meanwhile, a heating strip groove 704 is formed on the outer side surface of the salt spray cylinder 703, and a heating strip 705 is fixedly arranged inside the heating strip groove 704. After the heating strip 705 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 the corrosion resistance test.

[0052] In addition, a heating strip 705 is fixedly arranged inside the heating strip groove 704. The TC bearing can be heated through the heating strip 705. After the TC bearing is heated, it is then naturally cooled, and observing the temperature change is convenient for the cooling test of the TC bearing.

[0053] Furthermore, as Figure 3 、 Figure 5 and Figure 9 shown, the auxiliary limiting mechanism 4 includes a plurality of limiting telescopic rods 401 and an auxiliary limiting plate 402 arranged at the output end of the limiting telescopic rod 401. A baffle through hole 403 is formed on the auxiliary limiting plate 402, and a baffle 307 is fixedly arranged on the connecting cylinder 302. The baffle 307 is slidably arranged inside the baffle through hole 403. An auxiliary limiting mechanism 4 cooperating with the internal detection mechanism 3 is arranged on the outer side surface of the internal detection mechanism 3, which can limit and support the TC bearing, and at the same time can abut against one side surface of the TC bearing to improve the stability of the TC bearing.

[0054] Still further, as Figure 1 and Figure 2 shown, a triangular support frame 8 is arranged on one side of the internal stress detection device 1. A plurality of triangular fixed connection blocks 801 are arranged on the triangular support frame 8. The internal stress pushing telescopic rod 301 and the limiting telescopic rod 401 are both fixedly arranged on the triangular fixed connection blocks 801. The bottom of the triangular support frame 8 is connected with a support base 9 through a triangular support foot 802. The internal stress pushing telescopic rod 301 and the limiting telescopic rod 401 are fixed through the triangular fixed connection blocks 801 on the triangular support frame 8 to improve the stability of the internal detection mechanism 3 and the auxiliary limiting mechanism 4. The other end of the support base 9 is connected with a flat angle support frame 901 through a flat angle support foot 902. The external stress pushing telescopic rod 201 and the corrosion resistance detection telescopic rod 701 are both fixedly arranged on the flat angle support frame 901. The corrosion resistance detection telescopic rod 701 and the external stress pushing telescopic rod 201 are fixed through the flat angle support frame 901 to improve the stability of the external stress detection device 2 and the corrosion resistance detection mechanism 7. A recycling box 10 is arranged on the support base 9. The recycling box 10 is arranged directly below the external stress detection device 2. A recycling box 10 is arranged on the support base 9. After the atomized salt spray is cooled, it will liquefy into water and then drip into the inside of the recycling box 10, which is convenient for recycling waste liquid and other impurities and improves the convenience of use.

[0055] As Figures 1-9As shown, the usage method of the comprehensive TC bearing performance detection system provided in this embodiment includes the following steps:

[0056] Step 1: Bearing installation. First, the TC bearing is sleeved on the internal stress detection device 1, and then the first high-pressure air pump 6 is started to inflate the internal stress airbag 304 with gas to fixedly install the TC bearing.

[0057] Step 2: Inner diameter stress detection. After the TC bearing is sleeved on the internal stress airbag 304, the first high-pressure air pump 6 continuously inflates the inside of the internal stress airbag 304 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 304 inside the TC bearing, different positions of the TC bearing are detected.

[0058] Step 3: Outer diameter stress detection. The TC bearing is pushed into the internal stress detection device 2 by the internal detection mechanism 3. Then, after deflating, the internal stress airbag 304 is withdrawn from the TC bearing, and the external stress airbag 203 inside the external stress detection device 2 is started to squeeze the TC bearing to detect the external stress of the TC bearing.

[0059] Step 4: Torque detection. The TC bearing is pushed onto the torsion airbag 503 of the torque detection mechanism 5, and then the inside of the torsion airbag 503 is inflated. The TC bearing is then pushed into the internal stress detection device 2, and the external stress airbag 203 is used to fix the TC bearing. Then, the torque detection mechanism 5 is started to drive the torsion airbag 503 to rotate to complete the torque detection of the TC bearing.

[0060] Step 5: Corrosion resistance detection. The salt spray cylinder 703 is pushed into the inside of the TC bearing through the corrosion resistance detection telescopic rod 701. Then, the salt water in the salt water tank 11 is pumped and atomized by the atomizing pump 708, and then sprayed onto the inner side of the TC bearing through the spray nozzle 706 on the salt spray cylinder 703 for corrosion experiments.

[0061] Step 6: Cooling detection. The TC bearing is heated by the heating strip 705 on the heating strip groove 704 and then naturally cooled. The cooling speed of the TC bearing is detected by the change in temperature.
