[0013] The present invention also discloses a detection method based on a load-bearing capacity detection device for an automobile transmission shaft, which specifically comprises the following steps:

[0014] Step 1: The user places the automobile drive shaft on the fixed frame, and translates the automobile drive shaft so that the load-bearing end of the automobile drive shaft to be tested is moved to the lower side of the pressure piece, and the cylinders on both sides of the device are started. The cylinders drive the pressure frame downward. After the two pressure frames cooperate with the fixed frame to clamp the two sides of the automobile drive shaft, the cylinders are closed. At this time, the support frame fits the bottom of the automobile drive shaft, and the hydraulic cylinder is started. The hydraulic cylinder drives the pressure piece downward. After the bottom of the pressure piece contacts the upper end of the automobile drive shaft, the pressure piece gradually applies pressure to the automobile drive shaft under the action of the hydraulic cylinder. If the automobile drive shaft is deformed, the lower end of the automobile drive shaft bulges, and the convex end of the automobile drive shaft pushes the support frame downward. The support frame squeezes the second spring. Through the transmission of force, the pressure borne by the support frame is transmitted to the pressure sensor via the second spring. The pressure sensor transmits the pressure borne by the support frame to the terminal, and calculates the load-bearing capacity of the automobile drive shaft in conjunction with the pressure applied by the hydraulic cylinder.

[0015] Step 2: During the deformation of the automobile drive shaft, the deformed portion of the upper end of the automobile drive shaft pushes the rotating frame to rotate, and the rotating end of the rotating frame drives the pointer to rotate. When the user closes the hydraulic cylinder, the pointer and the dial are observed through the rectangular lens to obtain the rotation angle of the deformed end of the automobile drive shaft. During the deformation of the upper end of the automobile drive shaft, flying debris generated by the automobile drive shaft is blocked by the rotating frame. When the rotating frame rotates, it drives the first conductive block and the first spring to move upward through the connecting shaft. The first conductive block pushes the sliding rod to compress. After the hydraulic cylinder drives the pressure member to reset, the rotating frame is reset under the action of the first spring and the torsion spring.

[0016] Step 3: During the upward movement of the first conductive block, the first conductive block gradually contacts the first power-on block and the second power-on block. At this time, the external power supply supplies power to the air compressor through the second power-on block, the first conductive block, the first power-on block, and the first wire assembly. The air compressor draws in and compresses the outside air, and then the air compressor injects the compressed air into the ventilation filter plate through the jet pipe. The compressed air ejected by the air compressor is ejected through the rotating end of the rotating frame. The compressed air blows on the pressure block, the rotating frame, and the deformed end of the automobile drive shaft. While promoting the shedding of debris at the deformed end of the automobile drive shaft, the deformed end of the automobile drive shaft is blown to dissipate heat, thereby reducing subsequent cleaning steps.

[0017] Preferably, in step one, when the support frame moves downward, the second conductive block at the bottom of the support frame gradually contacts the energized seat. After the second conductive block contacts the energized seat, the external power supply supplies power to the warning light through the energized seat, the vehicle drive shaft, and the second wire assembly. The warning light lights up to remind the user that the vehicle drive shaft has been deformed, so that the user can close the hydraulic cylinder in time.

[0040] like Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 The third embodiment shown is mainly different from the second embodiment in that:

[0041] The adjusting member 722 is composed of a first conductive block 7221, a first power-carrying block 7222, a first wire assembly 7223, an air compressor 7224, a second power-carrying block 7225, an air jet pipe 7226, and a ventilation filter plate 7227.

At this time, the external power supply supplies power to the air compressor 7224 through the second power-on block 7225, the first conductive block 7221, the first power-on block 7222, and the first wire assembly 7223. The air compressor 7224 draws in and compresses the external air. Then, the air compressor 7224 injects the compressed air into the ventilation filter plate 7227 through the air injection pipe 7226.

While promoting the shedding of debris at the deformed end of the automobile transmission shaft 3, the deformed end of the automobile transmission shaft 3 is blown to dissipate heat, thereby reducing the subsequent cleaning steps.

[0043] like Figure 1 、 Figure 2 、 Figure 9 、 Figure 10 The fourth embodiment shown, the main difference from the third embodiment is;

[0044] The prompt member 14 is composed of an energized seat 141, a second wire assembly 142, and a prompt light 143. The front and rear sides of the connecting seat 1 are fixedly connected to the two energized seats 141 near the lower end of the second conductive block 13, and the front side of the connecting seat 1 is fixedly connected to the prompt light 143 near the upper end of the rectangular lens 15; the second wire assembly 142 is electrically connected to a second wire assembly 142 near the front side of the connecting seat 1, and the second wire assembly 142 is electrically connected to the external power supply near the back side of the connecting seat 1, and the upper side of the second wire assembly 142 is electrically connected to the prompt light 143; when the support frame 9 moves downward, the second conductive block 13 at the bottom of the support frame 9 gradually contacts the energized seat 141. After the second conductive block 13 contacts the energized seat 141, the external power supply supplies power to the prompt light 143 through the energized seat 141, the automobile transmission shaft 3, and the second wire assembly 142. The prompt light 143 lights up, reminding the user that the automobile transmission shaft 3 has been deformed, so that the user can close the hydraulic cylinder 6 in time.

[0045] The present invention also discloses a load-bearing capacity detection device and detection method based on an automobile transmission shaft, which specifically includes the following steps:

[0046] Step 1: The user places the automobile transmission shaft 3 on the fixed frame 2, and translates the automobile transmission shaft 3 so that the bearing capacity end of the automobile transmission shaft 3 to be tested is moved to the lower side of the pressure piece 7, and the cylinders 4 on both sides of the device are started. The cylinders 4 drive the pressure frame 5 to move downward. After the two pressure frames 5 cooperate with the fixed frame 2 to clamp the two sides of the automobile transmission shaft 3, the cylinders 4 are closed. At this time, the support frame 9 is in contact with the bottom of the automobile transmission shaft 3, and the hydraulic cylinder 6 is started. The hydraulic cylinder 6 drives the pressure piece 7 to move downward. After the bottom of the pressure piece 7 is connected with the upper end of the automobile transmission shaft 3, the pressure piece 7 is pressed downward. After the contact, the pressure member 7 gradually applies pressure to the vehicle transmission shaft 3 under the action of the hydraulic cylinder 6. If the vehicle transmission shaft 3 is deformed, the lower end of the vehicle transmission shaft 3 bulges. The bulging end of the vehicle transmission shaft 3 pushes the support frame 9 downward, and the support frame 9 squeezes the second spring 10. Through the transmission of force, the pressure on the support frame 9 is transmitted to the pressure sensor 11 via the second spring 10. The pressure sensor 11 transmits the pressure on the support frame 9 to the terminal and calculates the bearing capacity of the vehicle transmission shaft 3 in combination with the pressure applied by the hydraulic cylinder 6.

[0047] Step 2: During the deformation of the automobile transmission shaft 3, the deformed portion of the upper end of the automobile transmission shaft 3 pushes the rotating frame 73 to rotate, and the rotating end of the rotating frame 73 drives the pointer 74 to rotate. When the user closes the hydraulic cylinder 6, the pointer 74 and the dial 75 are observed through the rectangular lens 15 to obtain the rotation angle of the deformed end of the automobile transmission shaft 3. During the deformation of the upper end of the automobile transmission shaft 3, the flying debris generated by the automobile transmission shaft 3 is blocked by the rotating frame 73. When the rotating frame 73 rotates, it drives the first conductive block 7221 and the first spring 723 to move upward through the connecting shaft 721. The first conductive block 7221 pushes the slide bar 724 to compress. After the hydraulic cylinder 6 drives the pressure member 7 to reset, the rotating frame 73 is reset under the action of the first spring 723 and the torsion spring.

[0048] Step 3: During the upward movement of the first conductive block 7221, the first conductive block 7221 gradually contacts the first power-on block 7222 and the second power-on block 7225. At this time, the external power supply supplies power to the air compressor 7224 through the second power-on block 7225, the first conductive block 7221, the first power-on block 7222, and the first wire assembly 7223. The air compressor 7224 draws in and compresses the outside air, and then the air compressor 7224 injects the compressed air into the ventilation filter plate 7227 through the jet pipe 7226. The compressed air ejected by the air compressor 7224 is ejected through the rotating end of the rotating frame 73. The compressed air blows the pressure block 71, the rotating frame 73, and the deformed end of the automobile drive shaft 3. While promoting the shedding of debris at the deformed end of the automobile drive shaft 3, the deformed end of the automobile drive shaft 3 is blown to dissipate heat, thereby reducing the subsequent cleaning steps.

[0049] At the same time, the contents not described in detail in this specification belong to the existing technology known to those skilled in the art. In step one, when the support frame 9 moves downward, the second conductive block 13 at the bottom of the support frame 9 gradually contacts the energized seat 141. After the second conductive block 13 contacts the energized seat 141, the external power supply supplies power to the warning light 143 through the energized seat 141, the automobile transmission shaft 3, and the second wire assembly 142. The warning light 143 lights up, notifying the user that the automobile transmission shaft 3 has been deformed, so that the user can close the hydraulic cylinder 6 in time.

8. A detection method based on a load-bearing capacity detection device for an automobile transmission shaft according to any one of claims 3 to 7, characterized in that: The specific steps include: Step 1: The user places the automobile transmission shaft (3) on the fixed frame (2), and translates the automobile transmission shaft (3) so that the bearing end of the automobile transmission shaft (3) to be tested is moved to the lower side of the pressure member (7), and the cylinders (4) on both sides of the device are started. The cylinders (4) drive the pressure frame (5) to move downward. After the two pressure frames (5) cooperate with the fixed frame (2) to clamp the two sides of the automobile transmission shaft (3), the cylinders (4) are closed. At this time, the support frame (9) is in contact with the bottom of the automobile transmission shaft (3), and the hydraulic cylinder (6) is started. The hydraulic cylinder (6) drives the pressure member (7) to move downward. After the bottom of the pressure member (7) is in contact with the automobile transmission shaft (3), the hydraulic cylinder (6) is started. The hydraulic cylinder (6) drives the pressure member (7) to move downward. After the upper end contacts, the pressure member (7) gradually applies pressure to the automobile transmission shaft (3) under the action of the hydraulic cylinder (6). If the automobile transmission shaft (3) is deformed, the lower end of the automobile transmission shaft (3) bulges, and the bulging end of the automobile transmission shaft (3) pushes the support frame (9) to move downward. The support frame (9) squeezes the second spring (10). Through the transmission of force, the pressure borne by the support frame (9) is transmitted to the pressure sensor (11) through the second spring (10). The pressure borne by the pressure sensor (11) and the support frame (9) is transmitted to the terminal. In combination with the pressure applied by the hydraulic cylinder (6), the bearing capacity of the automobile transmission shaft (3) is calculated. Step 2: During the deformation of the automobile transmission shaft (3), the upper deformation portion of the automobile transmission shaft (3) pushes the rotating frame (73) to rotate, and the rotating end of the rotating frame (73) drives the pointer (74) to rotate. When the user closes the hydraulic cylinder (6), the pointer (74) and the scale plate (75) are observed through the rectangular lens (15) to obtain the rotation angle of the deformation end of the automobile transmission shaft (3). During the deformation of the upper end of the automobile transmission shaft (3), the flying debris generated by the automobile transmission shaft (3) is blocked by the rotating frame (73). When the rotating frame (73) rotates, it drives the first conductive block (7221) and the first spring (723) to move upward through the connecting shaft (721). The first conductive block (7221) pushes the slide bar (724) to compress. After the hydraulic cylinder (6) drives the pressure member (7) to reset, the rotating frame (73) is reset under the action of the first spring (723) and the torsion spring. Step 3: As the first conductive block (7221) moves upward, the first conductive block (7221) gradually contacts the first power block (7222) and the second power block (7225). At this time, the external power supply supplies power to the air compressor (7224) through the second power block (7225), the first conductive block (7221), the first power block (7222), and the first wire assembly (7223). The air compressor (7224) draws in and compresses the external air. The rear air compressor (7224) injects compressed air into the ventilation filter plate (7227) through the air jet pipe (7226). The compressed air ejected by the air compressor (7224) is ejected through the rotating end of the rotating frame (73). The compressed air blows the pressure block (71), the rotating frame (73), and the deformed end of the automobile transmission shaft (3). While promoting the shedding of debris at the deformed end of the automobile transmission shaft (3), the deformed end of the automobile transmission shaft (3) is blown to dissipate heat, thereby reducing the subsequent cleaning steps.

9. The detection method based on the load-bearing capacity detection equipment of the automobile transmission shaft according to claim 8, characterized in that: In step 1, when the support frame (9) moves downward, the second conductive block (13) at the bottom of the support frame (9) gradually contacts the energizing seat (141). After the second conductive block (13) contacts the energizing seat (141), the external power supply supplies power to the warning light (143) through the energizing seat (141), the vehicle transmission shaft (3), and the second wire assembly (142). The warning light (143) lights up, notifying the user that the vehicle transmission shaft (3) has been deformed, so that the user can close the hydraulic cylinder (6) in time.
