Technical Field
[0001] This invention relates to the field of inspection tool technology, specifically to an inspection tool for curved automotive parts. Background Technology
[0002] Inspection tools are simple tools used by industrial manufacturing enterprises to control the various dimensions of products, improve production efficiency and control quality, and are suitable for mass-produced products. In the processing of automotive parts, inspection tools are required to inspect curved automotive parts.
[0003] For example, a circular arc mold part inspection fixture with announcement number CN217465585U includes a base plate, an upper plate, a mounting plate, an upper inspection piece, and a side inspection piece. The upper plate is connected to the base plate via a cylinder. The base plate is provided with a positioning groove. A power component is provided on the upper plate. The mounting plate is movably connected to the push rod of the power component via the upper inspection piece. The mounting plate is connected to the upper plate via a guide shaft. The upper inspection piece is located directly above the positioning groove. The side inspection piece is connected to the upper inspection piece. The side inspection piece includes a connecting plate and an inspection piece. The inspection piece is connected to the lower part of the upper inspection piece via the connecting plate. This device reduces the intensity of manual labor, improves the efficiency of inspection, and reduces errors during inspection.
[0004] However, when inspecting the contour of curved parts, a profilometer is required. The sensor of the profilometer needs to slide along the surface being measured, and acquire data by sensing changes in the surface contour through a stylus. It also needs to be kept close to the curved surface of the stylus to reduce measurement errors caused by gaps. Existing profilometers generally use linear guide rails or lead screw assemblies to drive the stylus movement during inspection. Since the curvature contours of different curved parts are different, existing equipment may need to frequently correct the data to keep the stylus moving stably along the surface of the curved part. When the distance between the stylus and the curved part is too large, it will affect the contour detection accuracy of the curved part. When the distance between the stylus and the curved part is too small, it may cause the stylus to collide with the curved part, thereby reducing the inspection effect of the fixture. Summary of the Invention

[0022] By adopting the above technical solution, rotating the screw and guiding the guide rod to guide the pressure plate, so that the pressure plate is close to the body of the extrusion profiler.
[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: By setting the detection component, the unit block adapts to the curvature rotation of the arc-shaped part body, and the unit block assists in adsorption and pressing the arc-shaped part body. The contact plate adapts to the curvature deflection of the unit block, maintaining a constant distance between the measuring head and the arc-shaped part body for detection. This facilitates the autonomous adaptation to the contour detection of arc-shaped parts with different curvatures within a certain range, improving the fixing stability and detection accuracy of the arc-shaped part body. The specific details are as follows: 1. By setting up the detection components, the operator first activates the lower electric push rods on both sides. The lower electric push rods drive the clamping blocks to move, and the two clamping blocks clamp the two ends of the arc-shaped part body. Then, the upper electric push rod is activated, causing it to drive the extrusion rollers to rise. Multiple extrusion rollers press and fix the bottom of the arc-shaped part body. The main hydraulic rod is activated, causing the fixing plate and the arc-shaped part body to rise. The arc-shaped part body will extrude multiple unit blocks. The unit blocks drive the lower rotating rod and the collar to rise. The collar slides on the outside of the vertical rod and compresses the spring. The unit blocks... The unit block adapts to the curvature of the curved component's body, causing the lower rotating rod to rotate. The lower rotating rod acts on the second torsion spring, making the unit block essentially the same curvature as the curved component's body, facilitating subsequent inspection. The more unit blocks there are, the closer they fit the surface of the curved component's body. When the curved component's body approaches the unit block, it first squeezes the side rod. The side rod drives the inner plate to compress the second spring, and the inner plate drives the center rod and piston plate to rise. Then, the curved component's body squeezes the sealing ring. At this point, the piston plate and the curved component's body are in a sealed state. The curved component's body continues to squeeze the side rod... The piston plate continues to rise, increasing the space between the piston plate and the arc-shaped part body, thus reducing the pressure. This maintains the auxiliary adsorption and pressing of the unit block onto the arc-shaped part body. Then, the linear guide rail is activated, driving the moving seat and moving plate to move. The moving plate drives the outer profilometer body to move, allowing the profilometer body to perform profile detection through the measuring rod and measuring head. The spring telescopic rod presses the moving plate down, pressing the contact plate against the top surface of the unit block. The contact plate is compressed by the arc of the unit block, causing the upper rotating rod to rotate. The upper rotating rod acts on the torsion spring, allowing the contact plate to adapt to the arc deflection of the unit block. The length of the contact plate is greater than the distance between adjacent unit blocks, allowing the contact plate to move smoothly. Guided by the arc-shaped distributed unit blocks, the contact plate adapts to the arc trajectory of the arc-shaped part body, thus maintaining a constant distance between the measuring head and the arc-shaped part body for detection without contacting or colliding with the unit blocks. This facilitates autonomous adaptation to the profile detection of arc-shaped parts with different arcs within a certain range, improving the fixing stability and detection accuracy of the arc-shaped part body. 2. By setting auxiliary components, when inspecting arc-shaped parts with large width dimensions, the auxiliary electric push rod is activated. The auxiliary electric push rod drives the lower plate to descend, and the lower plate drives the pressure plate to descend, making the pressure plate flush with the profilometer body. Rotating the screw guides the pressure plate, causing the pressure plate to approach and press against the profilometer body. The profilometer body drives the crossbar to move, and the crossbar drives the connecting plate to move. The connecting plate stretches the spring four, thereby adjusting the position of the profilometer body. This facilitates the inspection of the profilometer at different positions, improving the inspection range and accuracy. Attached Figure Description

[0031] A collar 517 is evenly slidably installed on one side of the front of the vertical plate 3. A lower rotating rod 519 is rotatably connected to the outer side of the collar 517. A unit block 520 is fixedly connected to the outer end of the lower rotating rod 519. A torsion spring 521 is sleeved on the outer side of the lower rotating rod 519. A side rod 524 and a sealing ring 530 are slidably installed at the bottom of the unit block 520.
[0032] A lower electric push rod 511 is fixedly installed on one side of the inclined plate 510. A clamping block 512 is fixedly connected to the output end of the lower electric push rod 511. There are no fewer than three upper electric push rods 513. Vertical grooves 515 are evenly and vertically opened on one side of the front of the vertical plate 3. A vertical rod 516 is fixedly connected vertically inside the vertical groove 515. A collar 517 is slidably connected to the vertical rod 516.
[0033] A spring 518 is sleeved on the upper part of the vertical rod 516. The two ends of the spring 518 are fixedly connected to the inner top surface of the collar 517 and the vertical groove 515, respectively. The two ends of the torsion spring 521 are fixedly connected to the collar 517 and the unit block 520, respectively. The bottom of the unit block 520 is provided with a cylindrical groove 522 and a U-shaped groove 523.
[0034] Side rods 524 are slidably installed on both sides inside the U-shaped groove 523. An inner plate 525 is fixedly connected between the two side rods 524. The inner plate 525 is slidably connected to the U-shaped groove 523. A second spring 526 is fixedly connected to the top of the inner plate 525. The top of the second spring 526 is fixedly connected to the inner top surface of the U-shaped groove 523. A center rod 527 is fixedly connected to the bottom of the inner plate 525.
[0035] A piston plate 528 is fixedly connected to the bottom end of the center rod 527. The piston plate 528 fits against the inner wall of the cylindrical groove 522 and is slidably connected to the cylindrical groove 522. A spring 529 is fixedly connected between the piston plate 528 and the sealing ring 530. The sealing ring 530 is slidably connected to the cylindrical groove 522.
[0036] Example 1: As Figure 3 - Figure 13 As shown, the operator first activates the lower electric push rods 511 on both sides. The lower electric push rods 511 drive the clamping blocks 512 to move, and the two clamping blocks 512 clamp the two ends of the arc-shaped body 4. Then, the operator activates the upper electric push rod 513, which drives the extrusion rollers 514 to rise. The multiple extrusion rollers 514 press and fix the bottom of the arc-shaped body 4. The operator then activates the main hydraulic rod 58, which drives the fixing plate 59 and the arc-shaped body 4 to rise. The arc-shaped body 4 will then extrude multiple unit blocks 512. 20. Unit block 520 drives the lower rotating rod 519 and collar 517 to rise. The collar 517 slides on the outside of the vertical rod 516 and compresses the first spring 518. Unit block 520 will adapt to the curvature of the arc-shaped body 4. Unit block 520 drives the lower rotating rod 519 to rotate. The lower rotating rod 519 acts on the second torsion spring 521, so that unit block 520 basically presents the same curvature as the arc-shaped body 4, which is convenient for subsequent inspection. The more unit blocks 520 there are, the more closely they fit the surface of the arc-shaped body 4.
[0037] When the arc-shaped body 4 approaches the unit block 520, since the bottom height of the side rod 524 is lower than the bottom height of the sealing ring 530, the side rod 524 will be squeezed first. The side rod 524 drives the inner plate 525 to compress the second spring 526. The inner plate 525 drives the center rod 527 and the piston plate 528 to rise. Then the arc-shaped body 4 will squeeze the sealing ring 530. At this time, the piston plate 528 and the arc-shaped body 4 are in a sealed state. The arc-shaped body 4 continues to squeeze the side rod 524, and the piston plate 528 continues to rise, which increases the space between the piston plate 528 and the arc-shaped body 4 and reduces the pressure, thereby maintaining the auxiliary adsorption and pressing of the unit block 520 on the arc-shaped body 4.
[0038] Next, the linear guide 51 is activated, which drives the moving seat 52 and the moving plate 54 to move. The moving plate 54 drives the outer profilometer body 7 to move, so that the profilometer body 7 performs profilometry through the measuring rod 8 and the measuring head 9. The spring telescopic rod 53 presses down the moving plate 54, so that the contact plate 57 is pressed against the top surface of the unit block 520. The contact plate 57 is squeezed by the arc of the unit block 520, which will drive the upper rotating rod 55 to rotate. The upper rotating rod 55 acts on the torsion spring 56, so that the contact plate 57 will adapt to the arc deflection of the unit block 520.
[0039] The length of the contact plate 57 is greater than the distance between adjacent unit blocks 520, allowing the contact plate 57 to move smoothly. The contact plate 57 is guided by the arc-shaped distributed unit blocks 520, which facilitates the contact plate 57 to adapt to the arc-shaped trajectory of the arc-shaped part body 4, thereby maintaining the measuring head 9 at a constant distance from the arc-shaped part body 4 for detection, and preventing contact and collision with the unit blocks 520. This facilitates autonomous adaptation to the contour detection of the arc-shaped part body 4 with different curvatures within a certain range, improving the fixing stability and detection accuracy of the arc-shaped part body 4.
[0040] like Figure 1 and Figure 11 - Figure 13 As shown, an auxiliary component 6 is provided on one side of the front of the mounting bracket 2. The auxiliary component 6 includes a mounting plate 61 fixedly installed on the top of the contact plate 57. A crossbar 62 is fixedly connected to the inside of the mounting plate 61. A connecting plate 63 is fixedly connected to one end of the crossbar 62. A spring 64 is fixedly connected between the connecting plate 63 and the mounting plate 61.
[0041] The other end of the crossbar 62 is fixedly installed to the profilometer body 7. An auxiliary electric push rod 65 is symmetrically fixedly installed on the upper part of one side of the front of the mounting bracket 2. The bottom end of the telescopic part of the auxiliary electric push rod 65 is fixedly connected to the same lower plate 66.
[0042] The lower plate 66 has a screw 67 threaded in the middle. The end of the screw 67 near the mounting bracket 2 is rotatably connected to a pressure plate 68. The side of the pressure plate 68 near the lower plate 66 is symmetrically fixed with a guide rod 69, which is slidably connected to the lower plate 66.
[0043] Example 2: Figure 11 - Figure 13 As shown, when inspecting the body 4 of a large-width arc-shaped component, the auxiliary electric push rod 65 is activated, which drives the lower plate 66 to descend. The lower plate 66 then drives the pressure plate 68 to descend, making the pressure plate 68 flush with the profilometer body 7. The screw 67 is rotated, and the guide rod 69 guides the pressure plate 68, causing it to approach and press against the profilometer body 7. The profilometer body 7 then moves the crossbar 62, which in turn moves the connecting plate 63. The connecting plate 63 stretches the spring 64, allowing the position of the profilometer body 7 to be adjusted. This facilitates the inspection of profilometers at different positions, improving the inspection range and accuracy.
[0044] Working principle: When using this device, firstly, as... Figure 1 - Figure 13As shown, the operator first activates the lower electric push rods 511 on both sides. Two clamping blocks 512 clamp the two ends of the arc-shaped body 4, and multiple extrusion rollers 514 press and fix the bottom of the arc-shaped body 4. Then, the main hydraulic rod 58 is activated, causing the fixing plate 59 and the arc-shaped body 4 to rise. The arc-shaped body 4 will then press against multiple unit blocks 520. The unit blocks 520 will adapt to the curvature of the arc-shaped body 4, and the unit blocks 520 will provide auxiliary suction and pressing to the arc-shaped body 4. Then, the... The linear guide 51 drives the moving seat 52 and the moving plate 54 to move. The moving plate 54 drives the outer profilometer body 7 to move, so that the profilometer body 7 performs profilometry through the measuring rod 8 and the measuring head 9. The spring telescopic rod 53 presses down the moving plate 54, so that the contact plate 57 is pressed against the top surface of the unit block 520. The contact plate 57 is squeezed by the arc of the unit block 520, which drives the upper rotating rod 55 to rotate. The upper rotating rod 55 acts on the torsion spring 56, so that the contact plate 57 is pressed against the top surface of the unit block 520. The plate 57 adapts to the arc deflection of the unit block 520, and the length of the contact plate 57 is greater than the distance between adjacent unit blocks 520, allowing the contact plate 57 to move smoothly. The contact plate 57 is guided by the arc-shaped distributed unit blocks 520, which facilitates the contact plate 57 to adapt to the arc trajectory of the arc-shaped part body 4, thereby maintaining a constant distance between the measuring head 9 and the arc-shaped part body 4 for detection. When detecting the arc-shaped part body 4 with a large width, the auxiliary electric push rod 65 is activated, which drives the lower plate 66 to descend. The lower plate 66 drives the pressure plate 68 to descend, making the pressure plate 68 flush with the profilometer body 7. The screw 67 is rotated, and the guide rod 69 guides the pressure plate 68, causing the pressure plate 68 to approach and press the profilometer body 7. The profilometer body 7 drives the crossbar 62 to move, and the crossbar 62 drives the connecting plate 63 to move. The connecting plate 63 stretches the spring 64, allowing the position of the profilometer body 7 to be adjusted, thereby facilitating the detection of the profilometer at different positions and improving the detection range and detection accuracy.
