[0022] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0023] Please see Figures 1-6 This utility model provides a technical solution: a positioning fixture for sandblasting, comprising: a main frame 1, an adjustment device 3 rotatably connected to the outer wall of the main frame 1, a fixing device 2, the outer wall of the fixing device 2 being slidably connected to the outer wall of the main frame 1, the fixing device 2 including a fixing block 21, a fixing bolt 23 threadedly connected to the outer wall of the fixing block 21, a moving block 22 slidably connected to the outer wall of the fixing block 21, two sets of moving blocks 22 being provided, a shock-absorbing plate 25 being fixedly connected to the outer wall of the moving block 22, and the moving block 22 being pushed by the fixed block 21 due to the inclined surface design of the fixing block 21.
[0024] The fixing device 2 also includes a tension spring 24. The outer wall of the tension spring 24 is fixedly connected to the outer wall of the two sets of moving blocks 22 respectively. The outer wall of the moving blocks 22 is slidably connected to the groove of the outer wall of the main frame 1. The outer wall of the fixing bolt 23 is rotatably connected to the outer wall of the main frame 1. By setting the tension spring 24, the moving blocks 22 can be reset by themselves.
[0025] The adjusting device 3 includes an adjusting frame 31. A fixed plate 32 is slidably connected to the outer wall of the adjusting frame 31. A rotating roller 33 is rotatably connected to the inner wall of the adjusting frame 31. An adjusting bolt 34 is rotatably connected to the outer wall of the fixed plate 32 via a rotating bearing 35. The outer wall of the rotating bearing 35 is fixedly connected to the outer wall of the fixed plate 32. The inner wall of the rotating bearing 35 is fixedly connected to the outer wall of the adjusting bolt 34. The outer wall of the adjusting bolt 34 is threadedly connected to the inner wall of the adjusting frame 31. The outer wall of the adjusting frame 31 is rotatably connected to the outer wall of the main frame 1 via the rotating roller 33. The outer wall of the rotating roller 33 is fixedly connected to the outer wall of the main frame 1. By setting multiple sets of adjusting devices 3, and the adjusting devices 3 are linearly arrayed on the main frame 1, the adjusting device 3 at the corresponding position can be selected according to actual needs.
[0026] In use, the adjustment device 3 is first operated according to the size of the workpiece to be fixed. The outer wall of the adjustment frame 31 in the adjustment device 3 is rotatably connected to the outer wall of the main frame 1 through the rotating roller 33, and the outer wall of the rotating roller 33 is fixed to the outer wall of the main frame 1. By rotating the roller 33, the required adjustment device 3 is raised. Then, the position of the adjustment device 3 is finely adjusted. The outer wall of the adjustment bolt 34 is threadedly connected to the inner wall of the adjustment frame 31. The operator rotates the adjustment bolt 34. Due to the threaded connection between the adjustment bolt 34 and the adjustment frame 31, the fixing plate 32 can move on the adjustment frame 31, thereby realizing the fine adjustment of the position of the adjustment device 3 to adapt to the specific position requirements of the workpiece.
[0027] After adjusting the adjustment device 3, the workpiece is fixed using the fixing device 2. The operator rotates the fixing bolt 23, causing the fixing bolt 23 to move the fixing block 21 downward. As the fixing block 21 moves downward, it pushes the moving block 22 to slide in the groove of the main frame 1. There are two sets of moving blocks 22, and the outer walls of the two sets of moving blocks 22 are connected to each other by tension springs 24. As the moving block 22 slides, the shock-absorbing plate 25 fixed on the outer wall of the moving block 22 gradually approaches the fixing plate 32 of the adjustment device 3 and clamps the workpiece. The setting of the shock-absorbing plate 25 can buffer and dampen the shock while clamping the workpiece, avoiding damage to the surface of the workpiece. When the processing is completed and the workpiece needs to be released, the fixing bolt 23 is loosened, the tension spring 24 plays its role, and the moving block 22 is pulled back to its original position, so that the shock-absorbing plate 25 releases its clamping of the workpiece, making it easy to remove the workpiece.
