[0006] Preferably, a sliding sleeve is fixedly installed on the upper part of one side of each of the positioning strips via a connecting rod, a sliding rod is inserted into the interior of each of the sliding sleeves, one end of each of the sliding rods is fixedly connected to the top of the two equipment boxes respectively, the other end of each of the sliding rods is fixedly connected to the top of the two equipment boxes respectively via a fixing seat, a return spring is sleeved on the surface of each of the sliding rods, and both ends of each of the return springs are fixedly connected to the sliding sleeve and the fixing seat respectively.

[0007] Preferably, the second transmission assembly includes a shaft, which is fixedly installed at the output end of the drive motor. The surface of the drive motor is rotatably connected to the middle of two support seats through two bushings. A cam is fixedly installed at the middle of the shaft surface, with the top of the cam in close contact with the bottom of the contact frame.

[0008] Preferably, a driven bevel gear is meshed with the lower part of the surface of the driving bevel gear, the bottom of the driven bevel gear is rotatably connected to the top of the base plate, a sleeve is fixedly installed on the top of the driven bevel gear, and a transmission rod is movably inserted into the inside of both sleeves.

[0009] Preferably, four limiting blocks are fixedly installed at equal intervals in a ring at the lower end of the surface of the transmission rod, and four limiting grooves are opened at equal intervals in a ring on the inner wall of the sleeve, with the four limiting blocks slidably installed inside the four limiting grooves.

[0010] Preferably, an upper bearing is rotatably mounted on the upper end of the transmission rod surface, and a fixing strip is fixedly mounted on the surface of the upper bearing. The end of the fixing strip away from the upper bearing is fixedly connected to the moving platform.

[0011] Preferably, a lower bearing is rotatably mounted on the upper end of the sleeve surface, and a fixing frame is fixedly mounted on the surface of the lower bearing, with the bottom of the fixing frame fixedly connected to the top of the base plate.

[0012] Preferably, a drive sprocket is fixedly installed on the top of the transmission rod, a driven sprocket is fixedly installed on the surface of the rotating shaft, a chain is meshed between the driven sprocket and the drive sprocket, a positioning frame is rotatably installed on the top of the drive sprocket, and one end of the positioning frame is fixedly connected to the top of the moving table.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) When in use, the operator places the complex automotive interior parts on the top of the rotating table, and then the operator drives two cylinders to push the two equipment boxes to move towards each other. When the two equipment boxes move, they drive the slider to slide inside the slide groove, which increases the stability of the two equipment boxes when they move. When the two equipment boxes move towards each other, they drive several positioning bars to clamp the complex automotive interior parts through several moving bars. Because the surface shape of the complex automotive interior parts is uneven, when clamping, several moving bars on the two equipment boxes will shrink into the two equipment boxes according to the surface of the complex automotive interior parts. When the moving bars move, they drive the sliding sleeve to slide on the surface of the sliding rod through the positioning bars and connecting rods, and simultaneously squeeze the return spring, so as to ensure the stability of the moving bars while giving them an elastic return effect. When several moving bars shrink into the two equipment boxes, they squeeze the ball, squeezing the excess ball into other empty spaces to fill them, thereby achieving support for all moving bars, and thus achieving the clamping and positioning effect of several positioning bars on the complex automotive interior parts.

[0015] (2) After the complex automotive interior parts are positioned, the operator drives the drive motor to rotate the shaft inside the two bushings. When the shaft rotates, the cam intermittently pushes the contact frame upward. When the contact frame intermittently moves upward, it will drive the moving platform to move upward. When the moving platform moves upward, it will drive the two rectangular sleeves to move along the surface of the two rectangular rods, and at the same time drive the two rectangular rings to squeeze the two telescopic springs to contract. Thus, while ensuring the stable movement of the moving platform, the elasticity of the two telescopic springs can make the contact frame always in contact with the cam, and make the moving platform have the effect of elastic reset.

[0016] When the moving table moves vertically, it drives the rotating table to move vertically via the rotating shaft. At the same time, the moving table also pulls the transmission rod to move vertically along the inside of the sleeve via the fixed bar and the upper bearing. When the transmission rod moves vertically, it drives the four limit blocks to slide along the inside of the four limit grooves, which increases the stability of the transmission rod when it moves. When the transmission rod moves vertically with the moving table, it can ensure that the driving sprocket and the driven sprocket always remain parallel, thereby ensuring the rotational transmission effect between the driving sprocket and the driven sprocket.

[0017] While the shaft rotates, it also drives the driven bevel gear to rotate via the active bevel gear. When the driven bevel gear rotates, it drives the sleeve to rotate along the lower bearing. When the sleeve rotates, it drives the transmission rod to rotate along the upper bearing. When the transmission rod rotates, it drives the active sprocket to rotate along the positioning frame. When the active sprocket rotates, it drives the driven sprocket to rotate via the chain. The driven sprocket drives the rotating table to rotate via the rotating shaft. When the rotating table rotates, it drives the four arc-shaped slide bars to slide in the grooves on the mounting ring, which increases the stability of the rotating table. This allows the rotating table to rotate while moving vertically back and forth. In turn, it can make the complex automotive interior parts clamped and positioned on the rotating table move vertically back and forth and rotate, so that the two industrial vision cameras can perform multi-angle inspection of the complex automotive interior parts.

[0018] (3) This automotive interior parts inspection fixture can adaptively position and clamp automotive interior parts with complex shapes, making it very convenient to use and enabling quick and easy multi-angle inspection with excellent performance. Attached Figure Description

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0031] Example 1, by Figures 1 to 8The invention includes a base plate 1. Two support seats 2 are fixedly installed at the center of the top of the base plate 1. A rectangular rod 3 is fixedly installed on the top of each support seat 2. A rectangular sleeve 5 is fitted on the surface of each rectangular rod 3. A rectangular ring 4 is fixedly installed inside the lower part of each of the two rectangular sleeves 5. A telescopic spring 6 is fitted on the surface of each rectangular rod 3. The two ends of the two telescopic springs 6 are fixedly connected to the rectangular rod 3 and the rectangular ring 4, respectively. A movable stage 7 is fixedly installed between the tops of the two rectangular sleeves 5. A rotating shaft 8 is rotatably installed at the center of the top of the movable stage 7. A rotating stage 9 is fixedly installed on the top of the rotating shaft 8. A support frame 10 is fixedly installed at the rear of the top of the base plate 1. An industrial vision camera 11 is fixedly installed on the inner top and the upper part of one side of the support frame 10. Several positioning strips 12 are provided on both sides above the rotating stage 9. Cylinders 14 are fixedly installed at both ends of the rotating stage 9 through connecting frames 13. The transmission ends of the two cylinders 14 are provided with first transmission components. The two first transmission components are connected to several positioning strips 12. The positioning strips 12 are connected by a transmission. When the two cylinders 14 are running, the power is output to several positioning strips 12 through two first transmission components, so that several positioning strips 12 clamp and position complex automotive interior parts. A contact frame 29 is fixedly installed in the middle of the bottom of the moving platform 7. A drive motor 30 is fixedly installed on one side of the top of the base plate 1. The output end of the drive motor 30 is provided with a second transmission component. The second transmission component is connected to the contact frame 29 and the rotating shaft 8. When the drive motor 30 is running, the power is output to the contact frame 29 and the rotating shaft 8 through the transmission component, so that the contact frame 29 drives the moving platform 7 to move upward and the rotating shaft 8 drives the rotating platform 9 to rotate. Four arc-shaped sliding strips 25 are fixedly installed at equal intervals in a ring at the bottom of the rotating platform 9. Support rods 28 are fixedly installed on the opposite sides of the two rectangular sleeves 5. An installation ring 26 is fixedly installed between the tops of the two support rods 28. A ring groove 27 is opened on the top of the installation ring 26. The four arc-shaped sliding strips 25 are slidably installed inside the four ring grooves 27.

[0032] In use, the operator places the complex automotive interior parts on the top of the rotating platform 9. Then, the operator drives two cylinders 14 to drive two first transmission components. When the two first transmission components are running, they drive several positioning bars 12 to clamp and position the complex automotive interior parts. After the complex automotive interior parts are positioned, the operator drives the drive motor 30 to drive the second transmission component. When the second transmission component is running, it intermittently pushes the contact frame 29 upward. When the contact frame 29 is intermittently moving upward, it will drive the moving platform 7 upward. When the moving platform 7 moves upward, it will drive two rectangular sleeves 5 to move along the surface of two rectangular rods 3, and at the same time drive two rectangular rings 4 to squeeze two telescopic springs 6 to contract. Thus, while ensuring the stable movement of the moving platform 7, the elasticity of the two telescopic springs 6 can keep the contact frame 29 in contact with the cam 33, and give the moving platform 7 an elastic reset effect.

[0033] When the moving stage 7 moves vertically, it drives the rotating stage 9 to move vertically via the rotating shaft 8. At the same time, the second transmission component also drives the rotating stage 9 to rotate via the rotating shaft 8. When the rotating stage 9 rotates, it causes the four arc-shaped sliders 25 to slide within the grooves 27 on the mounting ring 26, increasing the stability of the rotating stage 9 during rotation. This allows the rotating stage 9 to rotate while moving vertically back and forth, enabling the complex automotive interior parts clamped and positioned on the rotating stage 9 to move vertically back and forth and rotate. This allows the two industrial vision cameras 11 to perform multi-angle inspection of the complex automotive interior parts. This makes the automotive interior parts inspection fixture adaptively positioned and clamped on complex-shaped automotive interior parts, which is very convenient to use and can quickly and easily perform multi-angle inspection, resulting in excellent performance.

[0034] In Embodiment Two, based on Embodiment One, both first transmission components include a device box 15. The two device boxes 15 are respectively fixedly installed on the transmission ends of the two cylinders 14. Several moving strips 16 are movably inserted into the sides of the two device boxes 15 that are close to each other. One end of each moving strip 16 is fixedly connected to several positioning strips 12. Several balls 18 are placed inside each of the two device boxes 15. A slider 23 is fixedly installed at the bottom of each of the two device boxes 15. Slide grooves 24 are opened on both sides of the top of the rotating platform 9, and the two sliders 23 are slidably installed. Inside the two slide grooves 24; a sliding sleeve 19 is fixedly installed on the upper part of one side of several positioning strips 12 via connecting rods 17. A sliding rod 20 is inserted into the inside of several sliding sleeves 19. One end of several sliding rods 20 is fixedly connected to the top of two equipment boxes 15 respectively. The other end of several sliding rods 20 is fixedly connected to the top of two equipment boxes 15 via fixing seats 21 respectively. A return spring 22 is sleeved on the surface of several sliding rods 20. Both ends of several return springs 22 are fixedly connected to the sliding sleeve 19 and the fixing seat 21 respectively.

[0035] The operator drives two cylinders 14 to push two equipment boxes 15 to move towards each other. As the two equipment boxes 15 move, they both cause the sliders 23 to slide inside the slide grooves 24, increasing the stability of the movement. When the two equipment boxes 15 move towards each other, they both use several moving strips 16 to drive several positioning strips 12 to clamp the complex automotive interior parts. Because the surface shape of the complex automotive interior parts is uneven, during clamping, the moving strips 16 on the two equipment boxes 15 will retract inwards according to the surface of the complex automotive interior parts. When the moving strips 16 move, they all drive the sliding sleeves 19 to slide on the surface of the sliding rod 20 through the positioning strips 12 and the connecting rods 17, and simultaneously compress the return springs 22. This ensures the stability of the moving strips 16 while giving them an elastic return effect. When several moving strips 16 retract into the two equipment boxes 15, they will compress the balls 18, squeezing the excess balls 18 into other empty spaces to fill them, thereby supporting all the moving strips 16 and achieving the clamping and positioning effect of several positioning strips 12 on complex automotive interior parts.

[0036] In Example 3, based on Example 1, the second transmission assembly includes a shaft 31, which is fixedly installed at the output end of a drive motor 30. The surface of the drive motor 30 is rotatably connected to the middle of two support seats 2 via two bushings 32. A cam 33 is fixedly installed at the middle of the surface of the shaft 31, and the top of the cam 33 is in close contact with the bottom of the contact frame 29. A drive bevel gear 34 is fixedly installed at the end of the shaft 31 away from the drive motor 30. A driven bevel gear 35 is meshed with the lower part of the surface of the drive bevel gear 34. The bottom of the driven bevel gear 35 is rotatably connected to the top of the base plate 1. A sleeve 36 is fixedly installed at the top of the driven bevel gear 35. A transmission rod 37 is movably inserted into the interior of each of the two sleeves 36. Four limiting blocks 38 are fixedly installed at equal intervals in an annular pattern at the lower end of the surface of the transmission rod 37. Four limiting grooves 39 are opened at equal intervals in an annular pattern on the inner wall of the sleeve 36. The four limiting blocks 38 are slidably installed inside the four limiting grooves 39.

[0037] An upper bearing 42 is rotatably mounted on the upper end of the transmission rod 37. A fixing strip 43 is fixedly mounted on the surface of the upper bearing 42. The end of the fixing strip 43 away from the upper bearing 42 is fixedly connected to the moving table 7. A lower bearing 40 is rotatably mounted on the upper end of the sleeve 36. A fixing frame 41 is fixedly mounted on the surface of the lower bearing 40. The bottom of the fixing frame 41 is fixedly connected to the top of the base plate 1. A drive sprocket 44 is fixedly mounted on the top of the transmission rod 37. A driven sprocket 46 is fixedly mounted on the surface of the rotating shaft 8. A chain 47 meshes between the driven sprocket 46 and the drive sprocket 44. A positioning frame 45 is rotatably mounted on the top of the drive sprocket 44. One end of the positioning frame 45 is fixedly connected to the top of the moving table 7.

[0038] After the complex automotive interior parts are positioned, the operator drives the drive motor 30 to rotate the shaft 31 inside the two bushings 32. When the shaft 31 rotates, it intermittently pushes the contact frame 29 upward through the cam 33. When the contact frame 29 moves upward intermittently, it drives the moving platform 7 upward. When the moving platform 7 moves vertically, it drives the rotating platform 9 to move vertically through the rotating shaft 8. At the same time, the moving platform 7 also pulls the transmission rod 37 vertically along the inside of the sleeve 36 through the fixing bar 43 and the upper bearing 42. When the transmission rod 37 moves vertically, it drives the four limit blocks 38 to slide along the inside of the four limit grooves 39, which increases the stability of the transmission rod 37 when it moves. When the transmission rod 37 moves vertically with the moving platform 7, it can ensure that the driving sprocket 44 and the driven sprocket 46 always remain parallel, thereby ensuring the rotational transmission effect between the driving sprocket 44 and the driven sprocket 46.

[0039] While the shaft 31 rotates, it also drives the driven bevel gear 35 to rotate via the driving bevel gear 34. When the driven bevel gear 35 rotates, it drives the sleeve 36 to rotate along the lower bearing 40. When the sleeve 36 rotates, it drives the transmission rod 37 to rotate along the upper bearing 42. When the transmission rod 37 rotates, it drives the driving sprocket 44 to rotate along the positioning frame 45. When the driving sprocket 44 rotates, it drives the driven sprocket 46 to rotate via the chain 47. The driven sprocket 46 drives the rotating table 9 to rotate via the rotating shaft 8. This allows the rotating table 9 to rotate while moving vertically back and forth, thereby enabling the complex automotive interior parts clamped and positioned on the rotating table 9 to move vertically back and forth and rotate.
