[0009] The bottom of the gantry surface is slidably connected with a moving base, both sides of the bottom of the moving base are fixedly connected with wedge-shaped clamping seats, and the surface of the moving base is threadedly connected with a transverse adjusting threaded rod.

[0010] The present invention further describes that both sides of the movable base are rotatably connected to hydraulic rods, the end of the hydraulic rod away from the movable base is rotatably connected to a rotating top frame, the top of the rotating top frame is fixedly connected to a T-shaped slider, and the bottom of the lifting heating seat is provided with a sliding rail adapted to the T-shaped slider.

[0011] The present invention further illustrates that the surface of the hydraulic rod is fixedly connected to a ferrule frame, the bottom of the ferrule frame is fixedly connected to an upper screw rod, the top of the wedge-shaped seat is fixedly connected to a lower screw rod, and the surface connected to the bottom end of the upper screw rod and the surface connected to the top end of the lower screw rod are both threadedly connected to an adjusting rotating ferrule.

[0017] The present invention further illustrates that the inspection method comprises the following steps:

[0018] Step 1: Place the body structure to be inspected on the placement disc, and turn the stop nut appropriately. At this time, since the compression spring will return to its original state after compression, the elastic force generated will cause the compression spring to open, thereby driving the limit slide bar and the clamping block to move toward the center of the placement disc until the clamping block abuts against the body structure, and then turn the stop nut until the stop nut abuts against the outer side of the lifting heating seat;

[0019] Step 2: Move the upper slide to the top of the positioning screw and turn the positioning nut to prevent the upper slide from moving down. Then start the motor to rotate the reciprocating screw and the half gear.

[0023] Step 6: Turn off the motor, pull the threaded slide rod to disengage the clamping block from the body structure, and then continue to rotate the retaining nut so that the retaining nut is against the outside of the lifting heating seat again, and then take out the body structure.

[0024] The present invention further illustrates that the impact rod in step 2 can be replaced, and the weight of the impact rod can be adjusted to adjust the impact force of the vehicle body structure.

[0025] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0026] (1) By setting up the inspection component and the impact component, the reciprocating screw can drive the movable slide to slide back and forth, the half gear can drive the movable internal gear plate to move back and forth, and then drive the detection probe to perform reciprocating scanning inspection at the position of the body structure, thereby realizing the function of adjusting the inspection position.

DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] refer to Figure 1 - Figure 5 The embodiment of the present invention provides a device and method for inspecting high-strength and tough body structural parts of a new energy vehicle, such as Figure 1 As shown, the high-strength and toughness body structure inspection device for new energy vehicles includes a gantry 1, a lifting and heating seat 2, an inspection component and an impact component. The inspection component includes a motor frame 3 and a supporting cross plate 4, and the impact component includes an upper slide 5 and a positioning screw 6.

[0043] like Figure 1 , Figure 8 and Fig.11As shown, the top of the lifting heating seat 2 is rotatably connected to a placement disc 7, and the placement disc 7 is used to place the body structure. The surface of the motor frame 3 is fixedly connected to the surface of one side of the gantry 1. The top of the motor frame 3 is fixedly connected to a motor 8. The output shaft of the motor 8 is fixedly connected to a half gear 9 through a coupling. When the motor 8 works, it drives the half gear 9 to start rotating through the output shaft. The surface of one side of the gantry 1 and located on both sides of the half gear 9 are fixedly connected with a support clamping shaft 10. The surface of the support clamping shaft 10 is slidably connected with a moving internal gear plate 11. Two support clamping shafts 10 are provided, which are respectively fixed on the surface of one side of the gantry 1 to support the sliding moving internal gear plate 11. The surface of the half gear 9 is meshed with the inner side of the moving internal gear plate 11. The rotation of the half gear 9 drives the moving internal gear plate 11 to reciprocate. The axis of the half gear 9 away from the motor 8 is fixedly connected to a reciprocating screw 12. The rotation of the half gear 9 Afterwards, it can also drive the reciprocating screw 12 to start rotating. The two sides of the supporting cross plate 4 are fixedly connected to the surface of the gantry 1. The surface of the reciprocating screw 12 is threadedly connected with a moving slide 13. The two sides of the moving slide 13 are slidably connected with a limit clamping rod 14. The limit clamping rod 14 limits the moving slide 13, so that the rotation of the reciprocating screw 12 drives the moving slide 13 to move back and forth. The bottom of the moving slide 13 and the moving inner tooth plate 11 are fixedly connected with a detection probe 15, and the detection probe 15 is used to inspect the vehicle body structure.

[0044] like Figure 2 , Figure 3 and Fig.10As shown, the surface of the upper slide 5 is slidably connected with the surface of the supporting cross plate 4, and the upper slide 5 can slide up and down on the supporting cross plate 4. The bottom end of the upper slide 5 penetrates the supporting cross plate 4 and extends to the bottom of the supporting cross plate 4. The bottom end of the upper slide 5 is fixedly connected with an impact rod 16. When the upper slide 5 slides along the supporting cross plate 4, it can drive the impact rod 16 to rise and fall, thereby hitting the vehicle body structure. The bottom end of the positioning screw rod 6 is fixedly connected with the top of the supporting cross plate 4, and the surface of the positioning screw rod 6 is slidably connected with the surface of the upper slide 5. The upper slide 5 can slide on the surface of the positioning screw rod 6; the surface of the positioning screw rod 6 and the position at the bottom of the upper slide 5 are threadedly connected with a positioning nut 17, which is set at the bottom of the upper slide 5, and the positioning nut 17 is used to position the upper slide 5. Vibrating cams 18 are fixedly connected to both ends of the reciprocating screw 12 and one side of the supporting cross plate 4. The rotation of the reciprocating screw 12 drives the vibrating cam 18 to start rotating. Elastic buffer pads 19 adapted to the vibrating cams 18 are fixedly connected to the bottom of both sides of the upper slide 5. When in use here, if the upper slide 5 needs to move up and down, the positioning nut 17 is rotated to the bottom of the locking screw 6, so that the rotation of the vibrating cam 18 can drive the elastic buffer pad 19 to rise and fall, and then lift the upper slide 5. When the raised part of the vibrating cam 18 loses contact with the elastic buffer pad 19, since the upper slide 5 has no support, the upper slide 5 falls instantly due to its own gravity, driving the impact rod 16 to continuously hit the body structure.

[0045] like Figure 2 , Figure 3 and Figure 5 As shown, the bottom of the surface of the gantry 1 is slidably connected with a mobile base 20, and a connecting and fixing rod is fixed at the bottom of the surface of the gantry 1. The mobile base 20 is installed on this connecting and fixing rod and can slide on its surface; both sides of the bottom of the mobile base 20 are fixedly connected with a wedge-shaped seat 25, and the surface of the mobile base 20 is threadedly connected with a transverse adjustment threaded rod 33, and the rotation of the transverse adjustment threaded rod 33 drives the mobile base 20 to move.

[0046] like Figure 4 - Figure 7As shown, both sides of the movable base 20 are rotatably connected with hydraulic rods 21, and one end of the hydraulic rod 21 away from the movable base 20 is rotatably connected with a rotating top frame 22, and the top of the rotating top frame 22 is fixedly connected with a T-shaped slider 23. The bottom of the lifting heating seat 2 is provided with a sliding rail 24 adapted to the T-shaped slider 23. The hydraulic rod 21 will extend and retract when working, thereby driving the T-shaped slider 23 on the top of the rotating top frame 22 to slide inside the sliding rail 24. During this process, the lifting heating seat 2 will also be slowly lifted up. The surface of the hydraulic rod 21 is fixedly connected with a ferrule frame 26, the bottom of the ferrule frame 26 is fixedly connected with an upper screw rod 27, the top of the wedge-shaped card seat 25 is fixedly connected with a lower screw rod 28, and the surface at the bottom end of the upper screw rod 27 and the surface at the top end of the lower screw rod 28 are both threadedly connected with an adjusting rotating ferrule 29, and the adjusting rotating ferrule 29 rotates to drive the upper screw rod 27 and the lower screw rod 28 to rotate, thereby changing the distance between the upper screw rod 27 and the lower screw rod 28, thereby changing the distance between the ferrule frame 26 and the wedge-shaped card seat 25, and here the wedge-shaped card seat 25 is in a fixed state, so that the hydraulic rod 21 will be gradually lifted due to the change in distance, further increasing the height that can be lifted and lowered. A transmission vertical rod 30 is fixedly connected to the bottom of the placement disc 7, one end of the transmission vertical rod 30 passes through the lifting and heating seat 2 and extends to the bottom of the lifting and heating seat 2, one end of the transmission vertical rod 30 located at the bottom of the lifting and heating seat 2 is fixedly connected to a rotating base 31, and an adjusting rotating rod 32 is slidably connected to the surface of the rotating base 31. After the adjusting rotating rod 32 rotates, it drives the rotating base 31 to start rotating, and then drives the transmission vertical rod 30 to rotate. The rotation of the transmission vertical rod 30 drives the placement disc 7 to rotate, which can control the position of the vehicle body structure on the top of the placement disc 7, further improving the adaptability of the inspection.

[0047] like Figure 3 and Fig. 9 As shown, one end of the transverse adjustment threaded rod 33 passes through the gantry 1 and extends to one side of the gantry 1, and one end of the transverse adjustment threaded rod 33 located on one side of the gantry 1 is fixedly connected to a transmission gear 34, and one side of the transmission gear 34 is fixedly connected to a rotating chuck 35. The rotating chuck 35 is used to rotate the transmission gear 34, and the rotation of the transmission gear 34 drives the transverse adjustment threaded rod 33 to rotate. The number of transmission gears 34 is set to two, and the two transmission gears 34 are symmetrically arranged on both sides of the bottom of the gantry 1, and a transmission tooth chain 36 is meshed between the surfaces of the two transmission gears 34. Two transmission gears 34 are set, and the transmission tooth chain 36 is meshed for transmission, so that after one transmission gear 34 rotates, it can drive the other transmission gear 34 to rotate together.

[0048] like Figure 3 and Figure 5As shown, both sides of the lifting heating seat 2 are slidably connected with threaded slide rods 37, one end of the threaded slide rods 37 is fixedly connected with a clamping block 38, the threaded slide rods 37 slide on both sides of the lifting heating seat 2, and then the threaded slide rods 37 drive the clamping block 38 to slide. The two sides of the clamping block 38 are fixedly connected to the limit sliding rod 39, the surface of the limit sliding rod 39 is slidably connected to the surface of the lifting and heating seat 2, and the surface of the limit sliding rod 39 is sleeved with a compression spring 40, which drives the limit sliding rod 39 and the clamping block 38 to move toward the center of the placement disk 7. The surface of the threaded sliding rod 37 and the surface located on the outer side of the lifting and heating seat 2 are threadedly connected with a stop nut 41, the surface of the reciprocating screw 12 is rotatably connected to the surface of the supporting cross plate 4, and the two ends of the limit clamping rod 14 are fixedly connected to the surface of the supporting cross plate 4. After the body structure is placed, the stop nut 41 is rotated. At this time, since the compression spring 40 will return to its original state after compression, the elastic force generated will cause the compression spring 40 to open, thereby driving the limit sliding rod 39 and the clamping block 38 to move toward the center of the placement disk 7 until the clamping block 38 is against the body structure, and then the stop nut 41 is rotated until the stop nut 41 is against the outer side of the lifting and heating seat 2, thereby completing the positioning of the body structure.

[0049] Working principle: first install the body structure parts, and place the body structure parts on the placement disc 7. Since the compression spring 40 will return to its original shape after compression, the elastic force generated will cause the compression spring 40 to open, and then drive the limiting slide bar 39 and the clamping block 38 to move toward the center of the placement disc 7 until the clamping block 38 abuts against the body structure parts, and then rotate the abutting nut 41 until the abutting nut 41 abuts against the outer side of the lifting heating seat 2, and then start the inspection work. In order to ensure the accuracy of the inspection structure and obtain multiple sets of data, multiple sets of inspections are required here, namely, normal temperature no-impact inspection, normal temperature impact inspection, high temperature no-impact inspection and high temperature impact inspection. In the specific implementation process, the positioning nut 17 is rotated to the position close to the top of the positioning screw rod 6, and then the upper slide 5 is lifted, so that the vibration cam 18 cannot contact the elastic buffer pad 19; turn on the motor 8. When the motor 8 is working, it drives the half gear 9 to start rotating through the output shaft. After the half gear 9 rotates, it drives the reciprocating screw 12 to rotate and the mobile inner tooth plate 11 to start moving. The limit clamp rod 14 limits the mobile slide 13, so that the reciprocating screw 12 rotates and drives the mobile slide 13 to reciprocate. The bottom of the mobile slide 13 and the mobile inner tooth plate 11 are fixedly connected with a detection probe 15, and the detection probe 15 is used to inspect the body structure parts, which is mainly a normal temperature non-impact inspection; the positioning nut 17 is rotated to the bottom of the clamping screw 6, and the reciprocating screw 12 rotates to drive the vibration cam 18 to rotate. When the raised part of the vibration cam 18 contacts the elastic buffer pad 19, the upper slide 5 is gradually lifted. When the raised part of the vibration cam 18 loses contact with the elastic buffer pad 19, the upper slide 5 has no support, and then the upper slide 5 falls instantly due to its own gravity, driving the impact rod 16 to continuously knock the body structure parts, so as to realize the inspection under the condition of being hit at normal temperature;Next, the hydraulic rod 21 is made to work, and the hydraulic rod 21 will be extended and retracted when working, thereby driving the T-shaped slider 23 on the top of the rotating top frame 22 to slide inside the sliding rail 24. In this process, the lifting heating seat 2 will also be slowly lifted up. In addition, the rotating sleeve 29 is adjusted to rotate and drive the upper screw 27 and the lower screw 28 to rotate, thereby changing the distance between the upper screw 27 and the lower screw 28, thereby changing the distance between the sleeve frame 26 and the wedge-shaped seat 25, and the wedge-shaped seat 25 is in a fixed state here. In this way, due to the change in distance, the hydraulic rod 21 will be gradually lifted, further increasing the height that can be lifted and lowered, and the rotating chuck 35 is used to rotate to drive the transmission gear 34 to rotate, and the transmission gear 34 is rotated to drive the horizontal adjustment threaded rod 33 to rotate, and at the same time, it is set The two transmission gears 34 are meshed and transmitted through the transmission tooth chain 36, so that one transmission gear 34 can drive the other transmission gear 34 to rotate together after rotating, and the horizontal adjustment threaded rod 33 is used to rotate and drive the mobile base 20 to move. In this way, the mobile base 20 drives the hydraulic rod 21 and its lifting heating seat 2 to move, and the position of the bottom detection probe 15 of the mobile slide 13 and the body structure is changed. At the same time, the hydraulic rod 21 drives the height of the lifting heating seat 2 to change the position of the bottom detection probe 15 of the mobile inner tooth plate 11 and the body structure, so as to adjust the inspection position of the body structure, increase the inspection surface, and finally control the heating and temperature rise of the lifting heating seat 2. Repeating the above inspection workflow can provide multiple sets of different data and improve the accuracy of the inspection results. ;

[0050] A method for inspecting high-strength and tough body structural parts of new energy vehicles comprises the following steps:

[0051] Step 1: Place the vehicle body structure to be inspected on the placement disc 7, and rotate the positioning nut 41 appropriately. At this time, since the compression spring 40 will return to its original state after compression, the elastic force generated will cause the compression spring 40 to open, thereby driving the limiting slide bar 39 and the clamping block 38 to move toward the center of the placement disc 7 until the clamping block 38 rests on the vehicle body structure, and then rotate the positioning nut 41 until the positioning nut 41 rests on the outer side of the lifting and heating seat 2.

[0052] Step 2: Move the upper slide 5 to the top of the locking screw 6, and rotate the positioning nut 17 to prevent the upper slide 5 from moving downward, then start the motor 8 to make the reciprocating screw 12 and the half gear 9 start to rotate, the reciprocating screw 12 drives the moving slide 13 to slide back and forth, the half gear 9 drives the moving internal gear plate 11 to move back and forth, and then drives the detection probe 15 to perform inspection without impacting the vehicle body structure.

[0053] Step three: Rotate the positioning nut 17 to the bottom end of the positioning screw 6. The reciprocating screw 12 rotates to drive the vibration cam 18 to rotate. When the raised part of the vibration cam 18 contacts the elastic buffer pad 19, the upper slide 5 is gradually lifted. When the raised part of the vibration cam 18 loses contact with the elastic buffer pad 19, the upper slide 5 has no support and then falls instantly due to its own gravity, driving the impact rod 16 to continuously hit the body structure, so as to realize inspection under the condition of impact.

[0054] Step 4: Use the rotating chuck 35 to drive the transmission gear 34 to rotate, and the rotation of the transmission gear 34 drives the horizontal adjustment threaded rod 33 to rotate, driving the mobile base 20 to move, and the mobile base 20 drives the hydraulic rod 21 and its lifting and heating seat 2 to move, changing the position of the bottom detection probe 15 of the mobile slide 13 and the body structure. At the same time, the hydraulic rod 21 drives the height of the lifting and heating seat 2 to change the position of the bottom detection probe 15 of the mobile inner gear plate 11 and the body structure, thereby achieving the function of adjusting the inspection position of the body structure.

[0055] Step 5: Control the heating and temperature rise of the lifting heating seat 2, and repeat steps 2 to 4 to achieve the inspection work in a high temperature environment.

[0056] Step 6: Turn off the motor 8, pull the threaded slide rod 37 to disengage the clamping block 38 from the body structure, then continue to rotate the stop nut 41 so that the stop nut 41 is against the outer side of the lifting heating seat 2 again, and then take out the body structure.

[0057] In step 2, the impact rod 16 can be replaced, and the weight of the impact rod 16 can be adjusted to adjust the impact force of the vehicle body structure.
