Detailed Implementation

[0022] Example 1

[0023] A positioning mechanism for processing automotive parts, such as Figures 1-2 As shown, it includes a worktable 1, four support columns 2 disposed at the bottom end of the worktable 1, four through slots 3 evenly distributed around the center of the worktable 1, a positioning component disposed in each through slot 3, and a driving component disposed below the worktable 1 and driving the positioning component to make vertical displacement within the through slot 3; as shown Figures 1-2 As shown, the positioning assembly includes an L-shaped movable plate 4 slidably disposed within the through groove 3, a first hydraulic rod 5 disposed on the L-shaped movable plate 4, and a positioning plate 6 disposed at the telescopic end of the first hydraulic rod 5; as shown Figure 2 As shown, the drive assembly includes a support plate 7 disposed on the support column 2. Figure 2 and Figure 3 In the middle, the support plate 7 is directly mounted on the two diagonally opposite support columns 2, the second hydraulic rod 8 is mounted on the support plate 7, and the connecting assembly is mounted between the telescopic end of the second hydraulic rod 8 and the four L-shaped movable plates 4. Further, as Figures 2-3 As shown, the connecting assembly includes a connecting plate 20 disposed at the telescopic end of the second hydraulic rod 8, and a connecting rod 10 disposed between the connecting plate 20 and the four L-shaped movable plates 4. Further, as... Figures 1-3 As shown, the side wall of the L-shaped movable plate 4 is provided with a first slider 11, and the inner wall of the through groove 3 is provided with a vertical sliding groove 12 that slides and engages with the first slider 11.

[0024] Working principle: The automotive part to be drilled, such as a car door, is placed on the worktable 1, positioned in the middle of the four positioning components. Then, the second hydraulic rod 8 is activated, causing the four positioning components to move upwards synchronously until the positioning plate 6 in the positioning components is completely removed from the through groove 3. During the upward movement of the positioning components, the first slider 11 slides upwards within the vertical slide groove 12. Subsequently, the four first hydraulic rods 5 are activated, causing the four positioning plates 6 to move towards the automotive part respectively, until they are in contact with all four sides of the automotive part and exert a certain amount of pressure, thus achieving the purpose of positioning the automotive part. Drilling operations can then proceed normally.

[0025] After the drilling operation is completed, the first hydraulic rod 5 is retracted to return the positioning plate 6 to its original position. Then the second hydraulic rod 8 is retracted to return the positioning component to its original position (at this time, the top of the positioning component is not higher than the top surface of the worktable 1). After that, the workers can move the drilled car parts away from the worktable 1.

[0026] Example 2

[0027] Based on Example 1, such as Figures 1-3 As shown, a second slider 14 is provided at the bottom of the positioning plate 6, and a horizontal groove 15 is provided at the top of the worktable 1 to slide in cooperation with the second slider 14. By setting the second slider 14 and the horizontal groove, the first slider 11 is located within the horizontal groove 15 during the process of the positioning plate 6 moving towards the automotive parts, thereby limiting the movement path of the positioning plate 6 and supporting the positioning plate 6.

[0028] Furthermore, because some automotive parts are in contact with the top surface of workbench 1 during drilling, the drill bit may penetrate workbench 1, causing damage to workbench 1. Therefore, if... Figures 1-3 As shown, the workbench 1 has multiple vertical holes 16 located between the four positioning components to facilitate the passage of drill bits. By providing multiple holes 16, it is convenient for the operator to adjust the drilling area of ​​the automotive parts to be directly above the holes 16, so that the drill bit can directly enter the holes 16 after drilling, without damaging the workbench 1.

[0029] like Figures 2-3 As shown, a receiving box 17 is provided at the bottom of the workbench 1, and the vertical projections of all holes 16 are located within the receiving box 17. Because some debris may fall into the holes 16 during drilling operations, the receiving box 17 collects this debris, thus preventing it from falling randomly onto the ground or the connecting plate 20. Furthermore, as... Figures 2-3 As shown, the receiving box 17 is movably mounted on the connecting plate 20. Figure 2As shown, when the drilling operation is not performed, there is a gap between the receiving box 17 and the bottom surface of the workbench 1, and when the drilling operation is performed, the receiving box 17 is just in contact with the ground, so that the collection of the debris can be effectively realized, and the receiving box 17 is convenient to take and place.
