[0015] The beneficial effects of the present invention are as follows:

[0016] 1. At present, when inspecting the door panels of automobiles, mechanical measurement is mostly used, and the deformation of the material is read manually. The use of pure mechanical means requires manual operation, has low precision and large errors. The present invention sets a lifting and measuring mechanism to record the initial value of the automobile door panel plastic parts, and then compares it with the deformed automobile door panel plastic parts, so as to record data more intuitively, which is faster and more accurate than manual reading.

[0017] 2. The surface of the door panel is relatively smooth, and direct clamping may cause it to fall off when pulled. The present invention sets a universal clamping mechanism to achieve pulling of the automobile door panel plastic parts at multiple angles, increase the detection positions for deformation of the automobile door panel plastic parts, and provide multi-dimensional experimental results. The clamping assembly is not likely to cause the automobile door panel plastic parts to fall off when clamping, thereby increasing the stability of the automobile door panel plastic parts when pulled.

[0018] 3. Since the automobile door panel plastic parts will shake when pulled, they need to be fixed. Since the bottom of the automobile door panel plastic parts may have uneven protrusions and depressions, the second suction cup cannot be completely adsorbed on the automobile door panel plastic parts. The present invention sets a fixing mechanism and a limiting ring to limit the soft cover to prevent it from being excessively squeezed under the pressure of the automobile door panel plastic parts. When the automobile door panel plastic parts contact the second suction cup, its bottom also contacts the pad, so that the bottom of the automobile door panel plastic parts is dispersed to contact the pad, thereby enhancing the stability of the automobile door panel plastic parts and preventing the automobile door panel plastic parts from being displaced when being pulled and deformed, resulting in deviations in subsequent measurements.

[0019] 4. When pulling, since the surface of the automobile door panel plastic part is relatively smooth, ordinary clamps are prone to slipping during pulling, affecting the effect of pulling and deformation. The present invention arranges a clamping assembly, and the rotating block is close to one end of the first suction cup to press the suction cup so that it is tightly sucked with the upper and lower surfaces of the automobile door panel plastic part. At the same time, the universal head drives the clamping plate to clamp the upper and lower sides of the automobile door panel plastic part, thereby increasing the clamping force with the automobile door panel plastic part and the friction force at the same time, so that the automobile door panel plastic part is not easy to fall off during pulling, and the surface of the automobile door panel plastic part is protected to avoid leaving marks on the surface of the automobile door panel plastic part.

[0035] The bottom of the column 2 is fixedly connected to the top of the base 1, the top of the measuring ruler 507 is slidably connected to the inner wall of the fixed plate 508, the bottom of the limit assembly 502 is slidably connected to the top of the fixed plate 508, four driving blocks 601 are evenly arranged to pull the automobile door panel plastic parts from multiple directions, and the top of the base 1 is evenly arranged with a fixing mechanism 7, and the bottom of the fixing mechanism 7 is slidably connected to the top of the base 1.

[0036] During operation, the staff first places the automobile door panel plastic part inside the lifting and measuring mechanism 5, records the initial value of the automobile door panel plastic part, then the lifting and measuring mechanism 5 descends, places the automobile door panel plastic part on the fixing mechanism 7, then the lifting and measuring mechanism 5 returns to its original position, the universal clamping mechanism 6 fixes the automobile door panel plastic part from four directions, and pulls it outward to deform it, the universal clamping mechanism 6 pulls the automobile door panel plastic part at different positions alternately, so that it is pulled from multiple angles, and after the automobile door panel plastic part is deformed, the lifting and measuring mechanism 5 descends, the fixing mechanism 7 restores the automobile door panel plastic part to its initial position, the fixing shell 501 covers the automobile door panel plastic part and aligns the measuring ruler 507 with the edge of the automobile door panel plastic part at this time, records the data and compares it with the initial data to obtain the deformation, then removes the automobile door panel plastic part, and measures the next automobile door panel plastic part.

[0037] The lifting and measuring mechanism 5 includes a fixed shell 501, the top of the fixed shell 501 is fixedly connected to the bottom of the hydraulic rod 4, the inner wall of the fixed shell 501 is fixedly connected to a fixed plate 508, the center of the fixed plate 508 is provided with a groove similar in shape to the automobile door panel plastic part, the bottom of the fixed plate 508 is evenly provided with measuring rulers 507, the measuring rulers 507 are evenly distributed along the edge of the groove on the fixed plate 508, the measuring rulers 507 extend out of the fixed plate 508 and contact with the automobile door panel plastic part, so as to obtain the initial value of the automobile door panel plastic part, after the pulling is completed, the measuring ruler 507 is extended again for measurement, and the two values ​​are recorded for comparison, and the top of the fixed plate 508 is evenly provided with a limit component 502;

[0038] The lifting and measuring mechanism 5 also includes a rotating frame 503, the bottom of which is rotatably connected to the top of the fixed plate 508. The rotating frame 503 is symmetrically arranged in two groups. The bottom of the rotating frame 503 is fixedly connected with a telescopic column 504. The rotating frame 503 is initially located at the edge of the fixed shell 501, avoiding the groove on the fixed plate 508. The bottom of the telescopic column 504 is fixedly connected with an automatic suction cup 505. The bottom of the fixed plate 508 is evenly provided with a supporting plate 506. The top of the supporting plate 506 is rotatably connected to the bottom of the fixed plate 508. Initially, the supporting plate 506 rotates to the edge beyond the groove of the fixed plate 508.

[0039] The staff places the automobile door panel plastic part on the bearing plate 506, and the limit assembly 502 adjusts the position of the automobile door panel plastic part so that it is located in the middle of the fixed plate 508. Then the rotating frame 503 rotates, and the automatic suction cup 505 is placed on the top of the automobile door panel plastic part, and sucks it tightly to keep the automobile door panel plastic part stationary. The internal power source of the fixed shell 501 drives the measuring ruler 507 to extend outward, contact the edge of the automobile door panel plastic part, and record the extended distance, which is the initial value. Then the measuring ruler 507 is retracted, and the hydraulic rod 4 drives the fixed shell 501 to move downward, so that the bottom of the automobile door panel plastic part contacts the fixing mechanism 7. At this time, the bearing plate 506 rotates, so that the bottom of the automobile door panel plastic part contacts the fixing mechanism 7 completely, and continues to press downward until the fixing mechanism 7 fixes the automobile door panel plastic part, and the hydraulic rod 4 drives the fixed shell 501 back to the initial position.

[0040] After the universal clamping mechanism 6 pulls and deforms the automobile door panel plastic part, the hydraulic rod 4 drives the fixed shell 501 to descend again, and places the deformed automobile door panel plastic part in the fixed shell 501. The automatic suction cup 505 absorbs the automobile door panel plastic part without changing the angle of the door panel after deformation. The load-bearing plate 506 holds the automobile door panel plastic part, and the measuring ruler 507 is extended again to measure the value of the edge of the automobile door panel plastic part at this time. The difference between the two measured data is the deformation amount.

[0041] The initial values ​​of the automobile door panel plastic parts are recorded, and then compared with the deformed automobile door panel plastic parts, so that the data can be recorded more intuitively, which is faster and more accurate than manual measurement.

[0042] The universal clamping mechanism 6 includes a driving block 601, the bottom of the driving block 601 is slidably connected to the top of the base 1, the outer wall of the driving block 601 is fixedly connected to a telescopic rod 602, and the end of the telescopic rod 602 away from the driving block 601 is rotatably connected to a universal head 603, the universal head 603 can drive the clamping assembly 604 to rotate at any angle, and the end of the universal head 603 away from the telescopic rod 602 is rotatably connected to the clamping assembly 604.

[0043] After the automobile door panel plastic part is fixed, the driving block 601 drives the telescopic rod 602 to extend, and gradually moves the clamping assembly 604 close to the edge of the automobile door panel plastic part. After the clamping assembly clamps the automobile door panel plastic part, the two opposite groups pull each other outward, and work alternately in pairs. When one group pulls outward, the other group keeps clamping but does not pull. Then the two opposite groups of clamping assemblies 604 are released, and the driving block 601 moves in the opposite direction and is located at the diagonal corner of the automobile door panel plastic part. When pulled, the automobile door panel plastic part will rotate, and the fixing mechanism 7 rotates with the automobile door panel plastic part. After pulling, the fixing mechanism 7 returns the automobile door panel plastic to its original position, and then another group of driving blocks 601 repeats the same action to pull another group of diagonal corners of the automobile door panel plastic part.

[0044] The automobile door panel plastic parts can be pulled at multiple angles, the detection positions of the automobile door panel plastic parts deformation are increased, and multi-dimensional experimental results are provided. The clamping assembly 604 is not easy to fall off when clamping the automobile door panel plastic parts, and the stability of the automobile door panel plastic parts when being pulled is increased.

[0045] The fixing mechanism 7 includes a rotating table 701, the bottom of the rotating table 701 is rotatably connected to the top of the base 1, the top of the rotating table 701 is fixedly connected to an air pump 702, the top of the air pump 702 is fixedly connected to a limiting ring 703, the top of the air pump 702 is fixedly connected to a second suction cup 705, the air pump 702 is turned on to drive the second suction cup 705 to be adsorbed on the plastic part of the automobile door panel, the outer wall of the air pump 702 is fixedly connected to a soft cover 704, the soft cover 704 is a soft rubber block, forming a sealed state, the inner wall of the soft cover 704 The wall contacts the outer wall of the second suction cup 705, the outer wall of the soft cover 704 is socketed with the inner wall of the limiting ring 703, and the top of the rotating table 701 is evenly provided with support rods 706, the bottom of the support rods 706 is rotatably connected to the top of the rotating table 701, and the top of the support rods 706 is fixedly connected with a pad 707, and the pad 707 is made of a material with relatively high elasticity. The bottom of the support rods 706 is fixedly connected with an elastic rod 708, and the bottom of the elastic rod 708 is fixedly connected to the top of the rotating table 701, and the elastic rod 708 is made of rubber.

[0046] Since the bottom of the automobile door panel plastic part may have uneven protrusions and depressions, the second suction cup 705 cannot be completely adsorbed on the automobile door panel plastic part. When the soft cover 704 contacts the bottom of the automobile door panel plastic part, due to its good elasticity, the top of the soft cover 704 is in close contact with the automobile door panel plastic part, so that the second suction cup 705 is in a sealed state, and the automobile door panel plastic part is sucked tightly. Compared with the automatic suction cup 505 which only fixes and lifts the automobile door panel plastic part and has a shorter service life, the second suction cup 705 has a better effect on the automobile door panel plastic part. The door panel plastic part plays a supporting role until it completes the pulling work, which requires stronger adsorption, and the limiting ring 703 limits the soft cover 704 to prevent it from being over-squeezed under the pressure of the door panel plastic part. When the door panel plastic part contacts the second suction cup 705, its bottom also contacts the pad 707, so that the bottom of the door panel plastic part is dispersed and in contact with the pad 707, thereby enhancing the stability of the door panel plastic part and preventing the door panel plastic part from being displaced when being pulled and deformed, resulting in deviations in subsequent measurements.

[0047] Embodiment 2, use Figure 1-Figure 8 A deformation detection device for automobile plastic parts according to one embodiment of the present invention is described as follows.

[0049] After placing the automobile door panel plastic part on the supporting plate 506, the electric push rod 5021 moves outward to make the limit rod 5024 contact the edge of the automobile door panel plastic part, and utilizes the induction of the laser sensor 5023 to make the distances between multiple groups of limit rods 5024 and the door panel consistent, which is used as the initial position of the automobile door panel plastic part. Then the measuring ruler 507 is extended to make the distance between each measuring ruler 507 and the edge of the automobile door panel plastic part equal, so that the initial value of the automobile door panel plastic part is more accurate, and the automobile door panel plastic part is not heavy and manual adjustment is more laborious.

[0051] When the telescopic rod 602 drives the universal head 603 to contact the edge of the automobile door panel plastic part, it first contacts the movable shell 6044 and pushes the movable shell 6044 to move inward, squeezing the spring 6045. During the movement of the movable shell 6044, the rotating block 6042 is driven to rotate. The rotating block 6042 is close to one end of the first suction cup 6043 to press the suction cup tightly so that it is sucked tightly against the upper and lower surfaces of the automobile door panel plastic part. At the same time, the universal head 603 drives the clamping plate 6046 to clamp the upper and lower sides of the automobile door panel plastic part, thereby increasing the clamping force with the automobile door panel plastic part and the friction force at the same time, so that the automobile door panel plastic part is not easy to fall off when pulled, and the surface of the automobile door panel plastic part is protected to avoid leaving marks on the surface of the automobile door panel plastic part.
