Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Please refer to Figures 1-5. This utility model provides a technical solution: a truck seat frame inspection tool, comprising: A fixed base plate 1 has a horizontal plate lifting drive mechanism 2 and a horizontal plate lifting guide mechanism 3 vertically fixedly mounted on its upper surface on the left and right sides respectively. The rear wall of the horizontal plate 4 is fixedly connected to the front end of the movable part of the horizontal plate lifting drive mechanism 2 and the horizontal plate lifting guide mechanism 3; A transverse clamping assembly 5 is provided in front of the horizontal plate 4, and a limitable rotation structure 6 is installed between its rear wall and the horizontal plate 4. The mobile image acquisition device 7 is located on the outside of the fixed base plate 1.

[0023] Specifically, in this embodiment, the fixed base plate 1 is fixed on the testing platform, which is a truck base frame testing platform. In this embodiment, a steel plate with threaded holes is used. Furthermore, the horizontal plate lifting drive mechanism 2 is used to drive the horizontal plate 4 to lift and lower, the lifting guide mechanism 3 guides the lifting and lowering of the horizontal plate 4 to ensure the smoothness of the lifting and lowering, the lateral clamping assembly 5 is connected to the horizontal plate 4 through the limitable rotation structure 6, the lateral clamping assembly 5 rotates on the horizontal plate 4 through the limitable rotation structure 6, the limitable rotation structure 6 limits and fixes the position of the lateral clamping assembly 5 after it flips up and down, and adjusts the angle of the truck seat frame clamped on the lateral clamping assembly 5; More specifically, the mobile image acquisition device 7 allows the detection viewing angle to be moved, making it easy to adjust the coverage position of the image acquisition area; Understandably, this device can also be used to detect other appearance defects on truck seat frames, such as whether the holes, contours, and surfaces are up to standard.

[0024] In some embodiments, the rotatable limiting structure 6 includes: Sleeve 61, the rear wall of which is integrally formed with a ring; A round rod 63 is inserted into the middle of the inner cavity of the sleeve 61, and its outer wall slides against the inner ring surface of the ring. A through hole 62 is provided in the middle of the horizontal plate 4 corresponding to the round rod 63; A limiting ring 64 is fixedly sleeved on the middle of the outer wall of the round rod 63, which is located at the rear end of the inner cavity of the sleeve 61; The front end of the round rod 63 passes through the through hole 62 and is fixedly connected to the middle of the rear wall of the transverse clamping assembly 5; A spring 65 is inserted into the sleeve 61, with its two ends abutting against the front wall of the limiting ring 64 and the rear wall of the cross plate 4, respectively. Positioning rods 67 are fixedly mounted on the upper and lower positions of the rear wall of the transverse clamping assembly 5, and positioning holes 66 are opened on the front wall of the transverse plate 4 corresponding to the positioning rods 67. The positioning rod 67 is inserted into the corresponding positioning hole 66.

[0025] Specifically in this embodiment, the positioning rods 67 on the rear wall of the transverse clamping assembly 5 are symmetrically arranged vertically. After the transverse clamping assembly 5 rotates 180 degrees with the round rod 63, the positioning rods 67 in the vertically flipped position can be inserted into the re-aligned positioning hole 66. Furthermore, when the rotatable limit structure 6 is in the limit state, the positioning rod 67 is inserted into the positioning hole 66 to limit the relative position of the transverse clamping assembly 5 and the horizontal plate 4. At this time, the spring 65 is raised and supported by no external force to maintain the current state. Before rotating the round rod 63 to drive the transverse clamping assembly 5 to flip up and down, the round rod 63 needs to be pushed forward to drive the limiting ring 64 to compress the spring 65. The round rod 63 moves forward, causing the transverse clamping assembly 5 and the positioning rod 67 to move forward. The positioning rod 67 moves forward and disengages from the corresponding positioning hole 66. At this time, sufficient external force is applied to overcome the friction between the limiting ring 64 and the spring 65. The round rod 67 drives the transverse clamping assembly 5 to rotate. The rotation angle is controlled at 180 degrees to drive the transverse clamping assembly 5 to flip up and down. Then, the pushing force on the round rod 63 is released, and the spring 65 drives the limiting ring 64 and the round rod 63 to reset. The positioning rod 67 on the rear wall of the transverse clamping assembly 5 at the front end of the round rod 63 is inserted into the corresponding positioning holes 66 at the front and rear to limit the rotation position of the transverse clamping assembly 5.

[0026] In some embodiments, the horizontal lifting drive mechanism 2 includes: The first rectangular frame 21 is welded to the top surface of the fixed base plate 1 at its lower end, and the first rectangular frame 21 is arranged horizontally; The inner wall of the first rectangular frame 21 is rotatably fitted with screws 23 at the middle of the top and bottom surfaces; A first drive motor 22 is fixedly mounted in the middle of the top surface of the first rectangular frame 21, and its output end passes through the top surface of the first rectangular frame 21 and is fixedly connected to the upper end of the screw 23; The inner wall of the first rectangular frame 21 is slidably fitted with a first rectangular block 24, which is screwed to the outside of the screw rod 23; The left side of the rear wall of the horizontal plate 4 is fixedly connected to the front end of the first rectangular block 24.

[0027] Specifically, in this embodiment, the first drive motor 22 is a servo motor, which drives the screw 23 to rotate in both directions. The rotating screw 23 drives the first rectangular block 24 on it to move up and down along the inner wall of the first rectangular frame 21. Furthermore, the lifting and lowering of the first rectangular block 24 causes the front-end fixed horizontal plate 4 to rise and fall accordingly, and the lifting and lowering of the horizontal plate 4 causes the horizontal clamping component 5 fixedly connected to it to rise and fall. It is understandable that the rear wall of the horizontal plate 4 does not fit against the front wall of the first rectangular frame 21 to avoid friction affecting the lifting and lowering of the horizontal plate 4.

[0028] In some embodiments, the horizontal plate lifting guide mechanism 3 includes: The second rectangular frame 31 is welded to the top surface of the fixed base plate 1 at its lower end, and the second rectangular frame 31 is arranged horizontally; Guide rods 32 are fixedly connected to the middle of the top and bottom surfaces of the inner wall of the second rectangular frame 31; The inner wall of the second rectangular frame 31 is slidably fitted with a second rectangular block 33, which is slidably sleeved on the outside of the guide rod 32; The right side of the rear wall of the horizontal plate 4 is fixedly connected to the front end of the second rectangular block 33.

[0029] Specifically, in this embodiment, after the horizontal plate lifting drive mechanism 2 drives the horizontal plate 4 to rise and fall, the second rectangular block 33 fixed at the rear end of the horizontal plate 4 slides on the outer wall of the guide rod 32. This is how the horizontal plate 4 is raised and lowered. Longitudinal movement guides and limits movement, improving the stability of the lifting and lowering of the horizontal plate 4 and the lateral clamping assembly 5. In some embodiments, the lateral clamping assembly 5 includes: Strip 51, which is arranged horizontally; Vertical plates 52 are fixedly assembled on both the left and right edges of the front wall of the strip plate 51; A two-way threaded rod 54 is rotatably assembled between the two upright plates 52; A second drive motor 53 is fixedly mounted on the outer wall of one side plate 52, and its output end passes through the same side plate 52 and is fixedly connected to the end of the bidirectional threaded rod 54. The two-way threaded rod 54 has a first connecting plate 55 screwed to both sides of its outer wall, and its outer wall slides against the front wall of the strip plate 51. The first connecting plate 55 has a clamping plate 56 attached to its front end in a detachable fixed assembly.

[0030] Specifically in this embodiment, the second drive motor 53 is a servo motor, which drives the bidirectional threaded rod 54 to rotate in both directions. Furthermore, the bidirectional threaded rod 54 drives the first connecting plate 55, which is symmetrically threaded on both sides of its upper outer wall, to move in opposite directions along the front wall of the strip plate 51. The movement of the first connecting plate 55 drives the two clamping plates 56 to move in opposite directions. Understandably, the two side clamps 56 move towards each other to clamp onto the outer wall of the truck seat frame, and the two side clamps 56 move in opposite directions to release the clamp on the truck seat frame.

[0031] In some embodiments, anti-slip pads 8 are attached to the opposite surfaces of the two side clamps 56. The anti-slip pads 8 serve to prevent slippage, making the two side clamps 56 more stable when holding the truck seat frame.

[0032] In some embodiments, the mobile image acquisition device 7 includes: The first base plate 71 has casters 72 evenly fixedly mounted on its bottom surface; A bearing seat 73 is fixedly assembled in the middle of the upper surface of the first base plate 71, and a telescopic rod 74 is fixedly assembled on its inner ring surface. A camera mechanism 75 is hinged to the upper end of the telescopic pole 74.

[0033] Specifically, in this embodiment, the first base plate 71 and the casters 72 are combined to form a movable base, which facilitates the movement of the device; Furthermore, the lower end of the telescopic rod 74 can rotate within the bearing seat 73 to adjust the orientation of the camera mechanism 75; More specifically, the camera mechanism 75 is hinged to the upper end of the telescopic rod 74. The camera mechanism 75 can be adjusted in elevation, and the extension and retraction of the telescopic rod 74 can drive the camera mechanism 75 to adjust in height. It is understandable that the purpose of the above-mentioned adjustment methods is to change the position corresponding to the acquisition area of ​​the camera mechanism 75.

[0034] In some embodiments, the telescopic rod 74 includes: The lower cylindrical tube 741 has its lower outer wall fixedly mounted on the inner ring surface of the bearing seat 73; A piston rod 742 is slidably inserted into the upper end of the lower cylinder 741, and its upper end is hinged to the camera mechanism 75; A limit bolt 743 is screwed onto the upper end of the outer wall of the lower cylinder 741, and its end abuts against the outer wall of the piston rod 742.

[0035] Specifically in this embodiment, the limiting bolt 743 is used to limit the relative position between the lower cylinder 741 and the piston rod 742; Furthermore, when it is necessary to adjust the length of the telescopic rod 74, after loosening the limiting bolt 743, slide the piston rod 742 to adjust its position inside the lower cylinder 741. After adjusting the piston rod 742 to the appropriate position, tighten the limiting bolt 743 to limit and fix the position of the piston rod 742.

[0036] In some embodiments, the camera mechanism 75 includes: The second connecting plate 751 is hinged to the upper end of the piston rod 742 via a pivot, and the second connecting plate 751 is positioned by friction at the contact point with the outer wall of the piston rod 742; The upper end of the second connecting plate 751 is fixedly equipped with a camera 752.

[0037] Specifically in this embodiment, the second connecting plate 751 is attached to the outer wall of the piston rod 742. When the second connecting plate 751 rotates around the axis of rotation, an external force is required to overcome the friction between the second connecting plate 751 and the outer wall of the piston rod 742. After the external force is removed, this friction is used to limit the relative position between the second connecting plate 751 and the piston rod 742, and plays a positioning role. This positioning role has taken into account the gravity of the camera 752. It is understandable that the friction between the second connecting plate 751 and the outer wall of the piston rod 742 can be achieved by setting a textured surface on the contact surface or by setting an anti-slip pad on the contact surface. Camera 752 is used to acquire images at the solder joints and can be connected to other inspection equipment for magnified display of the images, which is a common application of existing technology.

[0038] In some embodiments, the fixed base plate 1 includes: The second base plate 11 has fixing bolts 12 passing through the four corners of its upper surface; A triangular reinforcing rib 13 is fixedly assembled between the upper surface of the second base plate 11 and the lower end of the outer wall of the horizontal plate lifting drive mechanism 2 and the horizontal plate lifting guide mechanism 3.

[0039] Specifically in this embodiment, the second base plate 11 is connected to the preset threaded hole on the detection platform by fixing bolts 12; Furthermore, the addition of triangular reinforcing ribs 13 enhances the strength of the connection and fixation between the second base plate 11 and the horizontal plate lifting drive mechanism 2 and the horizontal plate lifting guide mechanism 3.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
