[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5As shown, this utility model is a support frame for machining and grinding the rear axle of a light truck drive, including a worktable 1; a moving component is provided at one end of the worktable 1; the moving component includes a robotic arm 18; a fixing component is provided on the worktable 1; the fixing component includes a lower fixing block 2; a work box 19 is fixedly connected to one end of the robotic arm 18; a rotating shaft 24 is rotatably connected inside the work box 19; a grinding motor 23 is fixedly connected to the top of the work box 19; the grinding motor 23 is connected to the rotating shaft 24; a grinding wheel 20 is fixedly connected to one end of the rotating shaft 24 extending out of the work box 19; and a fan blade 25 is fixedly connected to the rotating shaft 24 inside the work box 19.

[0026] By placing the drive rear axle on the lower fixing block 2 in the fixing assembly, and then fixing the drive rear axle with the fixing assembly, the work box 19 is moved to the area of ​​the drive rear axle that needs to be polished by the robotic arm 18 in the moving assembly. Then, the polishing motor 23 is started, which drives the rotating shaft 24 to rotate. The rotating shaft 24 drives the polishing wheel 20 to rotate, and the rotating polishing wheel 20 polishes the drive rear axle. At the same time, the rotating shaft 24 also drives the fan blade 25 to rotate. The fan blade 25 generates airflow to blow off the dust and debris polished by the polishing wheel 20. The worktable 1 has holes in the middle, and the debris and dust blown off by the fan blade 25 will fall into the bottom of the worktable 1 and be collected after polishing. This setting avoids the accumulation of dust and debris on the worktable 1, which would cause dust and debris to get stuck in the running parts and accelerate the wear of the parts. The work box 19 has air inlet and air outlet holes to facilitate airflow.

[0027] Please refer to the attached image. Figure 1 , Figure 2 and Figure 5 As shown, specifically, a lower fixing block 2 is fixedly connected to the worktable 1; a support block 22 is fixedly connected to one end of the worktable 1; a support frame 8 is fixedly connected to the support block 22; a drive rod 9 is rotatably connected inside the support frame 8; a first moving block 11 is rotatably connected to the drive rod 9; a bracket 7 is fixedly connected to the first moving block 11; an upper fixing block 6 is fixedly connected to the end of the bracket 7 away from the first moving block 11. During operation, by rotating the drive rod 9 inside the support frame 8, the rotating drive rod 9 drives the first moving block 11 to move up and down, and the up and down moving first moving block 11 also drives the bracket 7 to move. This allows the upper fixing block 6 on the bracket 7 to engage or disengage with the lower fixing block 2. This arrangement is to make the drive rear axle more firmly fixed on the worktable 1, preventing loosening or shaking during grinding.

[0028] Please refer to the attached image. Figure 1 and Figure 2As shown, specifically, a movable box 15 is fixedly connected to the end of the worktable 1 away from the support block 22; a one-way lead screw 14 is rotatably connected inside the movable box 15; a drive block 17 is rotatably connected to the one-way lead screw 14; and a robotic arm 18 is rotatably connected to the drive block 17. During operation, the rotation of the one-way lead screw 14 inside the movable box 15 will drive the drive block 17 on the one-way lead screw 14 to move left and right. The left and right movement of the drive block 17 will also cause the robotic arm 18 to move left and right. This arrangement is to make it easier for the grinding wheel 20 to grind the drive rear axle, and the direction can be changed at will according to the grinding position.

[0029] Please refer to the attached image. Figure 2 , Figure 4 and Figure 5 As shown, specifically, the drive rod 9 is rotatably connected to a second moving block 21 below the worktable 1; a collection box 16 is fixedly connected to the second moving block 21; a through slot 12 is provided on the worktable 1; the collection box 16 passes through the through slot 12; during operation, the drive rod 9 below the worktable 1 is configured with a thread opposite to that above the worktable 1, so when the drive rod 9 rotates, the first moving block 11 above the worktable 1 moves downward, and the second moving block 21 below the worktable 1 moves upward. The upward-moving second moving block 21 will drive the collection box 16 to pass through the through slot 12 on the worktable 1, and the collection box 16 will wrap around the worktable 1. This arrangement is to prevent dust and debris from falling out of the worktable 1 during grinding, and the debris and dust blown off by the fan blade 25 will also fall into the collection box 16, and then be disposed of uniformly after the process is completed.

[0030] Please refer to the attached image. Figure 1 , Figure 2 and Figure 5 As shown, specifically, a first through block 3 is fixedly connected to the lower fixed block 2; a second through block 4 is fixedly connected to the upper fixed block 6; a through rod 5 is fixedly connected to the worktable 1; the through rod 5 passes through the first through block 3 and the second through block 4; during operation, when the bracket 7 moves the upper fixed block 6 downward, to prevent the upper fixed block 6 from not aligning with the lower fixed block 2, causing a positional deviation that would make the drive rear axle unstable, the second through block 4 slides on the through rod 5. The through rod 5 passes through the first through block 3 and the second through block 4, so that the upper fixed block 6 and the lower fixed block 2 are at the same horizontal position and there will be no offset.

[0031] Please refer to the attached image. Figure 1 , Figure 4 and Figure 5As shown, specifically, a drive motor 10 is fixedly connected to the top of the support frame 8; the drive motor 10 is connected to the drive rod 9; a moving motor 13 is fixedly connected to one end of the moving box 15; the moving motor 13 is connected to the one-way lead screw 14; during operation, the drive rod 9 is driven to rotate by the drive motor 10, and the one-way lead screw 14 is driven to rotate by the moving motor 13. The drive motor 10 and the moving motor 13 provide kinetic energy to the drive rod 9 and the one-way lead screw 14, enabling them to work.

[0032] Please refer to the attached image. Figure 1 and Figure 4 As shown, specifically, there are two lower fixing blocks 2, which are symmetrically arranged on the worktable 1; there are two upper fixing blocks 6, which are symmetrically arranged on the bracket 7. During operation, the two lower fixing blocks 2 are set to make the drive rear axle more stable, and the two upper fixing blocks 6 are set to firmly fix the drive rear axle together with the lower fixing blocks 2, so that the grinding work can be carried out better.

[0033] The working principle of this utility model is as follows: The drive rear axle is placed on the lower fixing block 2 in the fixing assembly, and then the drive rear axle is fixed by the fixing assembly. After it is fixed, the work box 19 is moved to the area of ​​the drive rear axle that needs to be polished by the mechanical arm 18 in the moving assembly. Then, the polishing motor 23 is started, which drives the rotating shaft 24 to rotate. The rotating shaft 24 drives the polishing wheel 20 to rotate. The rotating polishing wheel 20 polishes the drive rear axle. At the same time, the rotating shaft 24 also drives the fan blade 25 to rotate. The fan blade 25 generates airflow to blow off the dust and debris polished by the polishing wheel 20. The worktable 1 has a hole in the middle. The debris and dust blown off by the fan blade 25 will fall into the bottom of the worktable 1 and be collected after polishing. This setting avoids the accumulation of dust and debris on the worktable 1, which would cause dust and debris to get stuck in the running parts and accelerate the wear of the parts. The work box 19 has an air inlet and an air outlet to facilitate airflow.
