Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example 1
[0025] As attached Figures 1 to 3 The intelligent lifting and sliding system for an automotive lower trim panel inspection fixture shown includes a support frame 1. A first motor 2 is bolted to one side of the support frame 1. The output end of the first motor 2 is connected to a first threaded rod 3 via a coupling. Slide plates 6 are welded and fixedly installed inside the support frame 1. Support slide rods 8 are slidably arranged on the left and right sides of the slide plates 6. A support plate 9 is welded and fixedly installed on the top of the support slide rods 8. A support frame 10 is detachably installed on the top of the support plate 9. A second motor 12 is arranged on one side of the support frame 10. A second threaded rod 13 is connected to the output end of the second motor 12. An internal threaded sleeve 15 is threadedly connected to the outer side of the second threaded rod 13. When the second threaded rod 13 rotates, the internal threaded sleeve 15 moves along its axial direction. A placement plate 18 is welded and fixedly installed on the top of the internal threaded sleeve 15. A lifter 19 is stably placed on the top of the placement plate 18. A support plate 20 is fixedly installed on the top of the lifter 19.
[0026] Specifically, the first motor 2, the second motor 12, and the support frame 10 are installed using detachable bolt connections, facilitating the installation, disassembly, and maintenance of the equipment, reducing maintenance costs and difficulty, and improving the equipment's operational flexibility. Furthermore, the cooperation between the first threaded rod 3 and the sliding plate 6 and the support sliding rod 8, as well as the threaded cooperation between the second threaded rod 13 and the internal threaded sleeve 15, enables the sliding of the bearing plate 9 and the axial movement of the placement plate 18, giving the system a sliding adjustment function to meet the inspection needs of different specifications of automotive lower trim panels. Additionally, a lifter 19 is installed on the top of the placement plate 18, which allows for the lifting and lowering of the support plate 20, further expanding the system's inspection range, improving the comprehensiveness and accuracy of the inspection, and providing strong support for high-quality inspection of automotive lower trim panels.
[0027] Example 2
[0028] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 3 As shown below, see details:
[0029] In a preferred embodiment, an inner threaded sleeve 4 is fitted onto the outer side of the first threaded rod 3 through a threaded engagement. As the first threaded rod 3 rotates forward and backward, the inner threaded sleeve 4 can reciprocate linearly along the axial direction of the first threaded rod 3. To ensure the stability and smoothness of the rotation of the first threaded rod 3, a first bearing 5 is provided at the end of the first threaded rod 3 away from the first motor 2, and the first bearing 5 is installed on the inner wall of the bearing frame 1, which effectively reduces the friction and shaking of the first threaded rod 3 during rotation.
[0030] In a preferred embodiment, the sliding plate 6 is symmetrically arranged on the left and right sides of the first threaded rod 3 to provide stable support for the entire sliding structure. The upper left and right sides of the sliding plate 6 are provided with slide rails 7. The cross-sectional shape of the slide rails 7 is adapted to the support slide rod 8, which has good guiding properties. The support slide rod 8 is embedded in the slide rail 7, and there is a suitable gap between the two. This ensures that the support slide rod 8 slides smoothly in the slide rail 7, and avoids shaking due to excessive gap, thereby ensuring the stability and reliability of the entire device during operation.
[0031] In a preferred embodiment, the bottom edge of the support frame 10 is provided with threaded holes evenly distributed. A positioning bolt 11 is installed inside the threaded hole. The external thread of the positioning bolt 11 engages with the internal thread of the threaded hole. The bearing plate 9 and the support frame 10 are positioned by the positioning bolt 11. Through this threaded connection, the bearing plate 9 and the support frame 10 are stably positioned.
[0032] In a preferred embodiment, a second bearing 14 is installed at one end of the second threaded rod 13. The inner diameter of the second bearing 14 matches the outer diameter of that end of the second threaded rod 13 to ensure a stable installation. During the assembly of the entire device, one end of the second threaded rod 13 of the second bearing 14 is embedded in a pre-designed mounting position inside the support frame 10, and the second bearing 14 is installed inside the support frame 10 to ensure the smooth and stable rotation of the second threaded rod 13.
[0033] In a preferred embodiment, a guide plate 16 is bolted to the inside of the support frame 10. The guide plate 16 is installed on the left and right sides of the second threaded rod 13, forming a symmetrical layout, which provides a stable guiding effect for the movement of subsequent components. A groove 17 is provided on the top of the guide plate 16. The width and depth of the groove 17 are accurately calculated so that it can perfectly match the relevant sliding components, ensuring that the sliding components can move smoothly in the groove 17 without deviation.
[0034] In a preferred embodiment, guide rods 26 are welded and fixedly installed on the left and right sides of the placement plate 18, respectively. The welding points are uniform and have high strength, ensuring that the guide rods 26 are firmly connected to the placement plate 18. The guide rods 26 are positioned directly above the guide plate 16, forming a vertical correspondence with the guide plate 16. The shape and size of the guide rods 26 are adapted to the groove 17 opened on the top of the guide plate 16. When the relevant components drive the placement plate 18 to move, the guide rods 26 can slide smoothly inside the groove 17, playing a good guiding and limiting role.
[0035] In a preferred embodiment, a positioning plate 21 is horizontally fixedly installed on the upper part of the support plate 20 by welding. The positioning plate 21 is flat and fits the support plate 20. At the same time, multiple fixing plates 22 are arranged horizontally and evenly on the upper part of the support plate 20. Clamping rods 23 are movably arranged on the upper side of each fixing plate 22, and multiple positioning holes 24 are evenly opened on the upper part of the clamping rods 23 at a certain interval.
[0036] In a preferred embodiment, the upper part of the fixing plate 22 is provided with a pin hole that matches the pin 25. When it is necessary to position the clamping rod 23, the pin 25 is inserted into the corresponding pin hole on the fixing plate 22, and at the same time, the pin 25 also passes through the hole on the clamping rod 23. Since the pin 25 cooperates with the pin hole and the hole on the clamping rod 23, this insertion connection method can effectively restrict the rotation or movement of the clamping rod 23, thereby achieving a stable positioning between the fixing plate 22 and the clamping rod 23 and ensuring the stability of the entire device structure.
[0037] In this embodiment, the first motor 2 and the second motor 12 are both commercially available devices known to those skilled in the art. They can be customized or selected according to actual needs. Here, we are only using them and have not made any structural or functional improvements. We will not go into details here.
[0038] The working process of this utility model is as follows: First, the support frame 10 is installed on the bearing plate 9 by the positioning bolt 11. The first motor 2 is started, and its output end drives the first threaded rod 3 to rotate in the first bearing 5 through the coupling. The inner threaded sleeve 4 moves accordingly, so that the support slide rod 8 slides in the slide rail 7 of the slide plate 6, driving the bearing plate 9 to move horizontally. Next, the second motor 12 on the support frame 10 is started, driving the second threaded rod 13 to rotate in the second bearing 14. The inner threaded sleeve 15 moves axially, adjusting the position of the placement plate 18. The guide rod 26 of the placement plate 18 slides in the groove 17 of the guide plate 16 in the support frame 10 to ensure stable movement. After that, the lifter 19 is placed stably on the placement plate 18, and the support plate 20 is fixed on its top. The support plate 20 is lifted and lowered by the lifter 19. The lower trim panel of the car is placed on the positioning plate 21 of the support plate 20. The clamping rod 23 on the fixed plate 22 is rotated, and the pin 25 is inserted into the pin hole of the fixed plate 22 and the positioning hole 24 of the clamping rod 23 to complete the positioning test of the lower trim panel. The above describes the working principle of this intelligent lifting and sliding system for automotive lower trim panel inspection.
