Description

Technical Field

[0001] This invention belongs to the field of automotive parts inspection technology, specifically referring to an inspection device for automotive longitudinal beam reinforcement components. Background Technology

[0002] The longitudinal beam reinforcement components of automobiles are critical parts of the chassis, crucial to the vehicle's safety, reliability, and durability. Their quality directly impacts performance; if the thickness does not meet design requirements or the surface is uneven, it can lead to reduced load-bearing capacity, stress concentration, deformation, and fracture, threatening driving safety. Therefore, rigorous thickness testing is a vital part of automobile manufacturing.

[0003] Existing reinforcement inspection technologies have several shortcomings: First, positioning and fixing are difficult. Traditional methods have low positioning accuracy, are not secure, and the fixtures are prone to loosening. Furthermore, they lack effective preliminary screening for offset mounting hole positions. Second, inspection accuracy is limited. Mechanical inspection is easily affected by interference, making it difficult to accurately detect thickness and surface unevenness, and failing to effectively identify potential stress concentration issues. Third, there is a lack of flexibility. Different types of reinforcements have different thickness requirements and inspection standards. Existing equipment is difficult to adjust parameters quickly, and modifications or replacements are costly, time-consuming, and inefficient. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides an inspection device for automotive longitudinal beam reinforcement, which effectively solves the above problems.

[0005] The technical solution adopted by this invention is as follows: This invention proposes an inspection device for automotive longitudinal beam reinforcement components, including a frame, an inspection positioning plate, an inspection rod assembly, and an adjustment device. The inspection positioning plate is disposed on the frame, and the inspection rod assembly and adjustment device are disposed within the inspection positioning plate. The adjustment device is located in the middle of the inspection rod assembly. A contouring seat is provided at the center of the frame, and a slide rail is also provided on the frame. The slide rail is located on one side of the contouring seat. Contouring wings are provided on both sides of the contouring seat. A positioning groove is provided on the top of the contouring seat, and a positioning column is provided at the center of the positioning groove. A clamping component rotating seat is provided below the contouring seat.

[0006] Furthermore, the frame also includes a clamping member and a sliding device. The clamping member is disposed on the conforming seat and includes a roller seat and a clamping member rotating rod. The clamping member rotating rod rotates on the clamping member rotating seat, and the sliding device slides on the slide rail.

[0007] Furthermore, the roller seat is provided with a pressure roller, and spring columns are provided on both sides of the roller seat. A pressure spring is provided on the spring column. The spring column slides on the clamping rotating rod, and the pressure spring is located between the clamping rotating rod and the spring column.

[0008] Preferably, the positioning groove and positioning post of the contouring seat are used to initially detect the positional deviation of the mounting hole of the reinforcing member. If there is a deviation, it cannot be inserted. The contouring side wing matches the outer contour of the reinforcing member, effectively preventing the reinforcing member from loosening during the test. The clamping member adopts a hinge rotation design. The clamping roller presses down on the contact point between the reinforcing member and the contouring side wing. The spring post and the clamping spring provide continuous elastic force for fixation, which solves the problem of easy loosening of traditional fixtures and ensures the stability of the reinforcing member position during the test.

[0009] Furthermore, the sliding device is provided with a sliding seat at the bottom, a support arm at the top, and rollers on both sides of the bottom of the sliding seat. The sliding seat slides on the slide rail, the rollers roll on the side wall of the slide rail, and the mounting plate is fixed to the end of the support arm.

[0010] Furthermore, the top of the detection positioning plate is provided with an indicator plate, the center of the detection positioning plate is provided with a rod group groove, the bottom of the detection positioning plate is provided with an adjustment groove, hydraulic pipe grooves are symmetrically provided on both sides of the adjustment groove, the side wall of the detection positioning plate is provided with an installation plate, the back of the indicator plate is provided with a pointer groove, the center of the indicator plate is provided with a balance bar slide groove, the pointer groove is located above the balance bar slide groove, and a buzzer is provided in the rod group groove.

[0011] Furthermore, the detection rod assembly includes a detection rod and a hydraulic pipe. The detection rod is mounted on the hydraulic pipe, which is located within a hydraulic pipe groove. A detection head is provided at the bottom of the detection rod, and a hydraulic plate is provided at the top of the detection rod. A hydraulic plate spring is provided at the top of the hydraulic plate, which is located within the hydraulic pipe. A thin top tube is provided above the hydraulic pipe.

[0012] Furthermore, the detection rod assembly also includes a liquid level rod and a balance rod. The bottom of the liquid level rod is located inside a thin top tube, and the top of the liquid level rod is provided with a liquid level rod top column. The balance rod slides in a balance rod groove, and top column grooves are provided on both sides of the balance rod. The liquid level rod top column is located in the top column groove.

[0013] Preferably, the hydraulic plate of the detection rod assembly cooperates with the hydraulic pipe. When the detection head contacts the surface of the reinforcing member and rises, the hydraulic plate rises, pushing the liquid in the hydraulic pipe into the narrow top tube, raising the liquid level rod, and thus pushing the balance rod upward. By amplifying the lifting height of the detection rod through the hydraulic system, accurate detection of the thickness of the reinforcing member can be achieved, avoiding errors that may occur from direct measurement using mechanical structures.

[0014] Furthermore, a pointer is provided on one side of the center of the balance bar, and a pressure-sensitive plate is provided on the other side of the center of the balance bar. The pointer is located in the pointer slot, and conductive plates are symmetrically provided on both sides of the top of the pointer. A conductive plate spring is provided between the conductive plates and the pointer.

[0015] Preferably, the device has dual functions of thickness over-limit alarm and thickness non-uniformity detection: a pressure-sensitive plate is provided on the top of the balance bar. When the thickness exceeds the threshold, the pressure-sensitive plate contacts the pressure detection plate and triggers the buzzer alarm; the top column grooves on both sides of the balance bar cooperate with the top column of the liquid level bar. If the surface thickness of the reinforcing member is uneven, the two detection rods will be raised to different heights. The balance bar tilts, causing the pointer to deflect. The conductive piece at the top of the pointer contacts the edge of the pointer groove and triggers the buzzer again, effectively identifying potential stress concentration hazards.

[0016] Furthermore, the adjusting device includes an adjusting plate, a connecting gear, and a rotating lead screw. The adjusting plate is disposed in an adjusting groove, and an internal gear ring is provided on the inner side of the adjusting plate. The connecting gear rotates within the adjusting groove, and the rotating lead screw is disposed within the internal gear ring. The connecting gear meshes with the internal gear ring, and a lead screw gear is provided at the bottom of the rotating lead screw. The lead screw gear meshes with the connecting gear.

[0017] Furthermore, the adjusting device also includes a lifting threaded column, which passes through the top of the adjusting groove and is connected by a thread. The bottom of the lifting threaded column is provided with a lead screw bushing, and the rotating lead screw slides inside the lead screw bushing. The top of the lifting threaded column is provided with a pressure-sensing plate spring, and the end of the pressure-sensing plate spring is provided with a pressure-sensing plate, which is located below the pressure-sensitive plate.

[0018] Preferably, the lifting threaded column of the adjustment device is threadedly connected to the top of the adjustment groove. Rotating the adjustment plate drives the rotating screw to rotate, and the height of the lifting threaded column is adjusted through gear transmission, thereby changing the position of the pressure plate. Different thickness detection benchmark values ​​of different reinforcing parts can be flexibly set to meet diverse production needs.

[0019] The beneficial effects achieved by the present invention using the above structure are as follows:

[0020] 1. The positioning groove and positioning post of the contouring seat are used to initially check the positional deviation of the reinforcing member mounting hole. If there is a deviation, it cannot be inserted. The contouring side wing matches the outer contour of the reinforcing member, effectively preventing the reinforcing member from loosening during the test. The clamping part adopts a hinge rotation design. The clamping roller presses the contact point between the reinforcing member and the contouring side wing. The spring post and the clamping spring provide continuous elastic force to fix it, which solves the problem of easy loosening of traditional fixtures and ensures the stability of the reinforcing member position during the test.

[0021] 2. The hydraulic plate and hydraulic pipe of the detection rod assembly work together. When the detection head contacts the surface of the reinforcing member and rises, the hydraulic plate rises, pushing the liquid in the hydraulic pipe into the narrow top tube, raising the liquid level rod, and thus pushing the balance rod upward. By amplifying the lifting height of the detection rod through the hydraulic system, accurate detection of the thickness of the reinforcing member can be achieved, avoiding errors that may occur from direct measurement using mechanical structures.

[0022] 3. The equipment has dual functions of thickness over-limit alarm and thickness unevenness detection: The top of the balance bar is equipped with a pressure-sensitive plate. When the thickness exceeds the threshold, the pressure-sensitive plate contacts the pressure detection plate and triggers the buzzer alarm; the top column grooves on both sides of the balance bar cooperate with the top column of the liquid level bar. If the surface thickness of the reinforcing part is uneven, the two detection rods will be raised to different heights. The balance bar tilts, causing the pointer to deflect. The conductive plate at the top of the pointer contacts the edge of the pointer groove and triggers the buzzer again, effectively identifying potential stress concentration hazards.

[0023] 4. The lifting threaded column of the adjustment device is connected to the top of the adjustment groove by thread. Rotating the adjustment plate drives the rotating screw to rotate, and the height of the lifting threaded column is adjusted through gear transmission, thereby changing the position of the pressure plate. Different thickness detection benchmark values ​​of different reinforcing parts can be flexibly set to meet diverse production needs. Attached Figure Description

[0045] The detection rod assembly 3 also includes a liquid level rod 33 and a balance rod 34. The bottom of the liquid level rod 33 is located inside the thin top tube 321, and the top of the liquid level rod 33 is provided with a liquid level rod top column 331. The balance rod 34 slides in the balance rod groove 212, and the balance rod 34 is provided with top column grooves 341 on both sides.

[0046] A pointer 342 is provided on one side of the center of the balance bar 34, and a pressure-sensitive plate 345 is provided on the other side of the center of the balance bar 34. The pointer 342 is located in the pointer slot 211. Conductive plates 344 are symmetrically provided on both sides of the top of the pointer 342. A conductive plate spring 343 is provided between the conductive plate 344 and the pointer 342.

[0047] The adjusting device 4 includes an adjusting plate 41, a connecting gear 42, and a rotating screw 43. The adjusting plate 41 is located in the adjusting groove 23. An internal gear ring 411 is provided on the inner side of the adjusting plate 41. The connecting gear 42 rotates in the adjusting groove 23. The rotating screw 43 is located in the internal gear ring 411. The connecting gear 42 is meshed with the internal gear ring 411. A screw gear 431 is provided at the bottom of the rotating screw 43.

[0048] The adjusting device 4 also includes a lifting threaded column 44, which passes through the top of the adjusting groove 23 and is connected by threads. The bottom of the lifting threaded column 44 is provided with a screw bushing 441, and the rotating screw 43 slides in the screw bushing 441. The top of the lifting threaded column 44 is provided with a pressure detection plate spring 443, and the end of the pressure detection plate spring 443 is provided with a pressure detection plate 442, which is located below the pressure sensing plate 345.

[0049] In practical use, the reinforcing member 5 to be tested is installed on the contour base 11. The positioning groove 112 and the positioning post 113 are used to initially check whether the mounting holes on the reinforcing member 5 are misaligned. If the mounting holes are misaligned, the reinforcing member 5 cannot be installed on the contour base 11. After the reinforcing member 5 is installed on the contour base 11, it is observed whether there is a significant gap between the contouring edge 111 of the contour base 11 and the reinforcing member 5. If there is no significant gap, the clamping member 13 is rotated so that the clamping roller 1 of the clamping member 13... 31. Press down on the joint between the reinforcing member 5 and the contoured wing 111 to fix the reinforcing member 5 and prevent it from loosening during subsequent testing. When the clamping member 13 is not in use, the clamping roller 131 hangs down below the clamping member rotating seat 114. When the clamping member 13 is rotated to clamp the reinforcing member 5, the clamping roller 131 rolls along the side wall of the contoured wing 111, which will pull the spring column 133 and compress the clamping spring 134, so that the reinforcing member 5 is fixed by the elastic force of the clamping spring 134.

[0050] After the reinforcing member 5 is fixed, the sliding device 14 is pushed to slide on the slide rail 12, so that the detection head 311 of the detection rod 31 slides on the surface of the reinforcing member 5 for detection. Initially, the bottom end of the detection head 311 is flush with the surface of the contour seat 11. As the reinforcing member 5 is installed on the contour seat 11, the detection rod 31 slides on the reinforcing member 5, causing the detection rod 31 to rise, and then the hydraulic plate 312 rises. As the hydraulic plate 312 rises, the liquid in the hydraulic pipe 32 enters the thin top pipe 321 and raises the liquid level rod 33, which in turn pushes the balance rod 34 to move upward. Initially, the pressure-sensitive plate 345 is attached to the pressure-detecting plate 442, and the pressure-detecting plate spring 443 is in a compressed state. As the balance bar 34 rises, the pressure-detecting plate spring 443 gradually returns to its original length, and then the balance bar 34 disengages from the pressure-detecting plate 442. Through the hydraulic system, the lifting height of the detection rod 31 is amplified to detect the thickness of the reinforcing member 5. During the detection process, when the pressure-sensitive plate 345 contacts the pressure-detecting plate 442, the buzzer 221 sounds a whistle, indicating that the thickness of the reinforcing member 5 is not qualified. At the same time, by rotating the adjusting plate 41, the rotating screw 43 is driven to rotate. The cross-section of the rotating screw 43 and the screw bushing 441 is polygonal. By rotating the screw 43, the lifting threaded column 44 is driven to rotate, which is used to adjust the height of the lifting threaded column 44, thereby adjusting the height of the pressure-detecting plate 442, and thus changing the value of the detected thickness of the reinforcing member 5.

[0051] During the process of detecting the thickness of the reinforcing member 5, if the surface thickness of the reinforcing member 5 is uneven, the lifting height of the two detection rods 31 will be different, which will cause the balance rod 34 to tilt, and then cause the pointer 342 to tilt. When the tilt reaches a certain degree, the conductive sheet 344 will adhere to the edge of the pointer groove 211. At this time, the buzzer 221 will sound a whistle, which means that the uneven surface thickness of the reinforcing member 5 is detected, which is very easy to cause stress concentration.

[0052] The above is the overall workflow of this invention. You can repeat this step the next time you use it. The actual operation process is very simple and easy.
