During production, vehicles are assembled from a number of auto parts. These auto parts require extremely high rigidity. If the rigidity is insufficient, the vehicle will be damaged, and in serious cases, it may cause incalculable casualties. By placing the automobile parts that need to be inspected in the pressing component assembly in the casing 1, the pressing component assembly pressurizes the automobile parts, and the inspection component inspects the automobile parts while pressurizing. When the pressing component assembly continues to pressurize the automobile parts, the inspection component continues to inspect the automobile parts to obtain whether the appearance of the automobile parts is deformed under the action of different pressures, thereby detecting the bending rigidity of the automobile parts. By performing rigidity testing on automobile parts, suitable automobile parts can be processed during automobile assembly to prevent damage due to insufficient rigidity when the automobile is driving, and at the same time avoid serious road damage caused by automobile damage. The setting of the hub 3 is convenient for reflecting the rigidity detection of automobile parts in the casing 1, which plays a role in facilitating observation.
[0023] like Figures 6 to 10 As shown, the pressing piece assembly includes a pressing piece ring block 19, which is symmetrically arranged inside the housing 1. The two pressing piece ring blocks 19 are slidably connected to the inner wall of the housing 1. The outer walls of the two pressing piece ring blocks 19 are fixedly installed with a moment rod 6. A gear 15 is arranged between the two moment rods 6. A motor 5 is fixedly installed on one side of the gear 15. The teeth on the gear 15 mesh with the teeth on the two moment rods 6. When pressurizing, the automobile parts are fixed between the two pressure ring blocks 19, and then the motor 5 is started. The motor 5 drives the gear 15 to rotate. While the gear 15 rotates, it drives the two torque rods 6 to move inward. The two torque rods 6 thereby drive the two pressure ring blocks 19 to apply pressure on the automobile parts. The gear 15 drives the two torque rods 6 to move and at the same time drives the two pressure ring blocks 19 to pressurize the automobile parts. The two pressure ring blocks 19 can be moved, which is convenient for pressurizing automobile parts of different lengths and plays a role in adapting to automobile parts of different lengths. It should be noted here that the power of the motor 5 and the relative movement distance of the two pressure ring blocks 19 need to be actually measured and calculated.

When the automobile parts are placed in the pressing ring blocks 19, one end of the automobile parts squeezes the fixing block 20 in the pressing ring block 19 to move in the slide groove 21. When the fixing block 20 is pressed, the push block 24 at one end of the fixing block 20 will push the sliding shaft 22 to squeeze the return spring 23 to slide on the limit slide plate 31. When the automobile parts move to a certain distance in the pressing ring block 19, the fixing block 20 is pressed. When the motor 5 stops rotating, the push block 24 will be moved back by the rebound force of the reset spring 23. When moving back, the multiple fixing blocks 20 will be in a four-corner clamping and fixing state to firmly fix the automobile parts. By clamping the automobile parts at the four corners by the multiple fixing blocks 20, the device can be adapted to a variety of different types of automobile parts. It should be noted that the shapes of the automobile parts to be adapted, except for the circular and rectangular shapes, the other shapes of the automobile parts need to be obtained by actual testing, and the elastic force of the reset spring 23 needs to be actually calculated.

When the door panel 2 is closed, the door panel 2 drives the pressure measuring tube 4 to move outside the pressure piece ring block 19 through the connecting piece 17. When the door panel 2 is closed, the two pressure measuring tubes 4 completely cover the two pressure piece ring blocks 19, so that the automobile parts are in a closed environment under pressurization, which is convenient for the subsequent inspection components to inspect the automobile parts and play a role in coordinating operations.

The inner walls of the two shift blocks 10 are respectively threadedly connected to the outer walls of the two threaded rods 12, and the two shift blocks 10 are slidably connected to the inner wall of the housing 1. When closing the door panel 2, the rotating cylinder 11 rotates to drive the threaded rod 12 to rotate. While the two threaded rods 12 are rotating, they drive the two door panels 2 to slide in the casing 1 through the shifting block 10, thereby closing the door panel 2. When the door panel 2 is closed, it drives the two pressure measuring cylinders 4 to completely cover the pressure ring block 19, which is convenient for subsequent inspection components to inspect automobile parts. By driving the door panel 2 and the pressure measuring cylinder 4 to move by the rotating cylinder 11, manpower can be greatly saved and the operation is convenient.
[0027] like Figure 6 to Figure 7 As shown, the inner sides of the two pressure ring blocks 19 are symmetrically fixedly connected with moment sealing plates 18, wherein the outer walls of the two moment sealing plates 18 are slidably connected with the inner walls of the other two moment sealing plates 18, and the inner sides of the two moment rods 6 are fixedly installed with arc sealing plates 16, wherein the outer wall of one arc sealing plate 16 is slidably connected with the inner wall of the other arc sealing plate 16, and the outer walls of the four moment sealing plates 18 are slidably connected with the inner walls of the two pressure measuring cylinders 4 in pairs, and the inner walls of the two arc sealing plates 16 are slidably connected with the outer walls of the two pressure measuring cylinders 4; When the two pressing ring blocks 19 move to fix the automobile parts, the two pressing ring blocks 19 drive the two pairs of moment sealing plates 18 to slide relative to each other while moving. At the same time, the two moment rods 6 drive the two arc sealing plates 16 to move relative to each other. When the two pressing ring blocks 19 completely fix the automobile parts, the two pairs of moment sealing plates 18 and the two arc sealing plates 16 stop moving, and then the door panel 2 is closed, and the rotating cylinder 11 drives the pressure measuring cylinder 4 to slide on the outer wall of the pressing ring block 19. When the door panel 2 is closed, the pressure measuring cylinder 4 just covers the pressing ring block 19, and the two pairs of moment sealing plates 18 and the two arc sealing plates 16 will block the opening on the pressure measuring cylinder 4, so that the pressure measuring cylinder 4 completely covers the pressing ring block 19 inside, forming a closed state, which is convenient for the subsequent inspection component to inspect the automobile parts. It should be noted here that the outer walls of the two pairs of moment sealing plates 18 and the two arc sealing plates 16 are inlaid with sealing rings, and the shape and size of the sliding opening on the pressure measuring cylinder 4 need to be actually measured and calculated.
[0028] like Figure 12 to Figure 13 As shown, the inspection component includes a capsule tube 7, which is symmetrically arranged inside the housing 1, and the inner walls of the two capsule tubes 7 are fixedly installed with a capsule partition plate 26, and the bottoms of the two capsule tubes 7 are fixedly installed with a gas distribution plate 25, and the tops of the two gas distribution plates 25 are symmetrically provided with air bags; When the two pressure measuring cylinders 4 completely cover the pressure ring block 19, air is ventilated to the air distribution disk 25 in the bag receiving cylinder 7, and the airbag in the bag receiving cylinder 7 will be ventilated and opened, and the airbag will fill the space in the pressure measuring cylinder 4. When the airbag is filled in the pressure measuring cylinder 4, the airbag will gradually fit the automobile parts. When a certain amount of air is passed into the airbag, the ventilation is stopped. At this time, the airbag will completely fill the pressure measuring cylinder 4, and the airbag will completely fit the automobile parts. At the same time, the airbag will fit the inner wall of the pressure measuring cylinder 4. When the pressure ring block 19 applies pressure to the automobile parts, causing the automobile parts to deform, the deformed parts of the automobile parts will be squeezed and fit together. When the airbag is closed, the pressure measuring tube 4 will receive a signal, and the central device 3 will display that the automobile part has been deformed, so that the maximum rigidity value of the automobile part can be found. Through the airbag detection, the whole body of the automobile part can be completely detected, which plays a role in detecting automobile parts without blind spots. The setting of the partition plate 26 allows two airbags to be symmetrically accommodated in the connecting tube 27. The shape design of the top of the partition plate 26 can facilitate the airbag to pass out of the airbag tube 7. The four airbags in the two airbag tubes 7 can facilitate the complete filling of the pressure measuring tube 4. It should be noted here that the material of the airbag needs to be actually measured.

When the air flow is extracted, the air bag on the top of the air distribution plate 25 will lose its filling. Driven by the suction force of the vacuum pump 9, the air bag in the pressure measuring cylinder 4 will be drawn back into the bag receiving cylinder 7, which plays the role of resetting the air bag, making it easier to take out the automobile parts and inspect the automobile parts next time.
[0031] like Figure 11 to Figure 12 As shown, the inner wall of the pressure measuring cylinder 4 is fixedly mounted with a detector 13, and a wire 14 is provided between the detector 13 and the pressure measuring cylinder 4; During operation, the airbag fits perfectly with the automobile parts, and at the same time, the airbag fits with the inner wall of the pressure measuring cylinder 4. When the pressure ring block 19 applies pressure to the automobile parts, causing the automobile parts to deform, the deformed part of the automobile parts will squeeze the airbag that fits with it, so that the detector 13 located in the pressure measuring cylinder 4 will detect the squeezing of the pressure measuring cylinder 4 through the wire 14, and then the detector 13 transmits the detected information back to the hub 3 for display, thereby realizing deformation detection.
[0032] Working principle: The automobile parts to be inspected are placed in the pressing component assembly in the housing 1, and the pressing component assembly pressurizes the automobile parts. The inspection component inspects the automobile parts while pressurizing. When the pressing component assembly continuously pressurizes the automobile parts, the inspection component continuously inspects the automobile parts to obtain whether the appearance of the automobile parts is deformed under the action of different pressures, thereby inspecting the bending rigidity of the automobile parts. By inspecting the rigidity of automobile parts, suitable automobile parts can be assembled and processed in the automobile to prevent damage caused by insufficient rigidity when the automobile is driving, and to avoid serious road damage caused by automobile damage. The setting of the central device 3 is convenient for reflecting the rigidity inspection of automobile parts in the housing 1, which plays a role in facilitating observation. When pressurizing, the automobile parts are fixed between the two pressing ring blocks 19, and then the motor 5 is started, and the motor 5 drives the gear 15 to rotate. While the gear 15 rotates, it drives the two moment rods 6 to move inward, and the two moment rods 6 drive the two pressing ring blocks 19 to apply pressure to the automobile parts. The two moment rods 6 are driven by the gear 15 to move and the two pressing ring blocks 19 are driven to pressurize the automobile parts. The two pressing ring blocks 19 can be moved, which is convenient for pressurizing automobile parts of different lengths, and plays a role in adapting to automobile parts of different lengths; When fixing the automobile parts, the automobile parts are placed horizontally between the two pressing ring blocks 19, and then the motor 5 is controlled to rotate so that the two pressing ring blocks 19 slowly approach the automobile parts. When the automobile parts are placed in the pressing ring block 19, one end of the automobile parts squeezes the fixing block 20 in the pressing ring block 19 to move in the slide groove 21. When the fixing block 20 is under pressure, the push block 24 at one end of the fixing block 20 will push the sliding shaft 22 to squeeze the return spring 23 to slide on the limiting slide plate 31. When the automobile parts move to a certain extent in the pressing ring block 19, the rotation of the motor 5 is stopped. At this time, the push block 24 will be moved back by the rebound force of the return spring 23. When moving back, multiple fixing blocks 20 will present a four-corner clamping and fixing state to firmly fix the automobile parts. By clamping and fixing the automobile parts at four corners by multiple fixing blocks 20, the device can be adapted to a variety of different types of automobile parts. When the automobile parts are fixed, the door panel 2 is closed. When the door panel 2 is closed, the door panel 2 drives the pressure measuring cylinder 4 to move outside the pressing ring block 19 through the connecting piece 17. When the door panel 2 is closed, the two pressure measuring cylinders 4 completely cover the two pressing ring blocks 19, so that the automobile parts are in a closed environment under pressure, which is convenient for the subsequent inspection component to inspect the automobile parts and play a role in cooperation with the operation; When closing the door panel 2, the rotating cylinder 11 rotates to drive the threaded rod 12 to rotate. The two threaded rods 12 drive the two door panels 2 to slide in the housing 1 through the moving block 10 while rotating, so that the door panel 2 is closed. When the door panel 2 is closed, it drives the two pressure measuring cylinders 4 to completely cover the pressing ring block 19, which is convenient for the subsequent inspection component to inspect the automobile parts. The rotating cylinder 11 drives the door panel 2 and the pressure measuring cylinder 4 to move, which can greatly save manpower and facilitate the operation. When the two pressing ring blocks 19 move to fix the automobile parts, the two pressing ring blocks 19 drive the two pairs of moment sealing plates 18 to slide relative to each other while moving. At the same time, the two moment rods 6 drive the two arc sealing plates 16 to move relative to each other. When the two pressing ring blocks 19 completely fix the automobile parts, the two pairs of moment sealing plates 18 and the two arc sealing plates 16 stop moving, and then the door panel 2 is closed, and the rotating cylinder 11 drives the pressure measuring tube 4 to slide on the outer wall of the pressing ring block 19. When the door panel 2 is closed, the pressure measuring tube 4 just covers the pressing ring block 19, and the two pairs of moment sealing plates 18 and the two arc sealing plates 16 will cover the opening on the pressure measuring tube 4, so that the pressure measuring tube 4 completely covers the pressing ring block 19 inside, forming a closed state, which is convenient for the subsequent inspection component to inspect the automobile parts; When the two pressure measuring cylinders 4 completely cover the pressure ring block 19, air is ventilated to the gas distribution disk 25 in the bag receiving cylinder 7, and the airbag in the bag receiving cylinder 7 will be ventilated and opened, and the airbag will fill the space in the pressure measuring cylinder 4. When the airbag is filled in the pressure measuring cylinder 4, the airbag will gradually fit with the automobile parts. When a certain amount of air is passed into the airbag, the ventilation is stopped. At this time, the airbag will completely fill the pressure measuring cylinder 4, and the airbag will completely fit with the automobile parts. At the same time, the airbag will fit with the inner wall of the pressure measuring cylinder 4. When the pressure ring block 19 applies pressure to the automobile parts, causing the automobile parts to deform, the automobile parts The deformed part will squeeze the airbag in contact with it, the pressure measuring tube 4 will receive a signal, and the central device 3 will show that the automobile part has been deformed, so that the maximum rigidity value of the automobile part can be found. Through the airbag detection, the whole body of the automobile part can be fully detected, which plays a role in detecting automobile parts without blind spots. The setting of the airbag plate 26 allows the connecting tube 27 to symmetrically accommodate two airbags. The shape design of the top of the airbag plate 26 can facilitate the airbag to pass through the airbag tube 7. The four airbags in the two airbag tubes 7 can facilitate the full filling of the pressure measuring tube 4. When the two pressure measuring cylinders 4 completely cover the pressing ring block 19, the blower 8 ventilates the second connecting pipe 28 through the air inlet pipe 29, and the introduced gas will flow along the two ends of the second connecting pipe 28 and finally enter the gas distribution plate 25 in the receiving bag cylinder 7. Then the gas in the gas distribution plate 25 enters the airbag to expand the airbag to fill and wrap the pressure measuring cylinder 4, thereby playing the role of ventilating the airbag; When the test is completed, the vacuum pump 9 enters the field to extract air, and the air flow in the air distribution plate 25 is extracted through the air extraction pipe 30 and the connecting pipe 27. When the air flow is extracted, the air bag on the top of the air distribution plate 25 will lose its filling. Driven by the suction force of the vacuum pump 9, the air bag in the pressure measuring cylinder 4 will be drawn back into the bag receiving cylinder 7, which plays the role of resetting the air bag, making it easier to take out the automobile parts and test the automobile parts next time. During operation, the airbag fits perfectly with the automobile parts, and at the same time, the airbag fits with the inner wall of the pressure measuring cylinder 4. When the pressure ring block 19 applies pressure to the automobile parts, causing the automobile parts to deform, the deformed part of the automobile parts will squeeze the airbag that fits with it, so that the detector 13 located in the pressure measuring cylinder 4 will detect the squeezing of the pressure measuring cylinder 4 through the wire 14, and then the detector 13 transmits the detected information back to the hub 3 for display, thereby realizing deformation detection.
