Therefore, we propose a fixed clamping device for camshaft production. Utility Model Content

[0004] The present invention proposes a fixed clamping device for camshaft production, which solves the problem that existing fixed clamping devices for camshaft production often require clamping and limiting the camshaft during use, but the clamping process is cumbersome, thus affecting the processing efficiency and convenience.

A support frame is fixedly connected to the top surface of the processing table, and a movable rod is slidably connected to the top of the extension of the support frame. A cylinder is fixedly connected to the top of the movable rod, and a fixed frame is fixedly connected to the surface of the cylinder. A groove is formed inside the top surface of the fixed frame, and a slider is connected through the groove. A piston rod is installed inside the fixed frame. A wedge is fixedly connected to the top of the piston rod, and a roller is slidably connected to the inclined surface of the wedge. A fixed shaft is fixedly connected inside the roller, and the first end of a tension spring is provided in the middle of the fixed shaft. A movable frame is fixedly connected to the middle of the roller, and a pin is rotatably connected to the top of the movable frame. A movable clamping frame is installed in the middle of the pin, and a fixed clamping frame is integrally connected to the top of the fixed frame.

[0007] This utility model further illustrates that: the support frame forms a sliding structure through a movable rod, and the movable rod and the cylinder form a fixed structure; the support frame forms a fixed structure through a threaded rod and the movable rod.

[0008] This utility model further illustrates that: the cylinder forms a movable structure through the piston rod and the inclined wedge block, the groove forms a sliding structure through the slider, and the slider and the inclined wedge block form a fixed structure.

[0009] This utility model further illustrates that: the inclined wedge block is closely fitted with the roller, and the roller forms a tension structure with the tension spring through a fixed shaft.

[0010] This utility model further illustrates that: the roller forms a rotating structure through the movable frame and the pin shaft, and the movable clamping frame forms a rotating structure through the movable frame and the fixed frame.

[0011] The advantages of this utility model are:

[0012] 1. This utility model features a threaded rod. By removing the threaded rod, the movable rod inside the moving support frame can be moved back and forth at any time by the cylinder that is fixedly connected to it. When it is moved to a suitable position, the threaded rod is threadedly connected to the movable rod through the support frame to fix the movable rod. This allows the user to easily adjust and fix the rod back and forth, thereby improving processing efficiency.

[0013] 2. This utility model, by setting a piston rod, pressurizes the cylinder, causing the piston rod to move the wedge block downwards together, overcoming the tension of the compression spring, thereby causing the movable clamping frame to open. When the cylinder is depressurized, the piston rod, through the compression spring, lifts the wedge block, causing the movable rod to move, realizing the closure of the movable clamping frame and the fixed clamping frame, clamping the camshaft, making it convenient for users to clamp the camshaft and enhancing the convenience of processing.

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 scope of protection of the present utility model.

[0020] Please see Figure 1-3 As shown, a fixed clamping device for camshaft production includes a processing table 1. A support frame 2 is fixedly connected to the top surface of the processing table 1, and a movable rod 3 is slidably connected to the top of the extension of the support frame 2. A cylinder 4 is fixedly connected to the top of the movable rod 3, and a fixed frame 5 is fixedly connected to the surface of the cylinder 4. A groove 6 is formed inside the top surface of the fixed frame 5, and a slider 7 is connected through the groove 6. A piston rod 8 is installed inside the fixed frame 5. A wedge block 9 is fixedly connected to the top of the piston rod 8, and a roller 10 is slidably connected to the inclined surface of the wedge block 9. A fixed shaft 11 is fixedly connected inside the roller 10. The head end of a tension spring 12 is provided in the middle of the fixed shaft 11. A movable frame 13 is fixedly connected to the middle of the roller 10, and a pin 14 is rotatably connected to the top of the movable frame 13. A movable clamping frame 15 is installed in the middle of the pin 14, and a fixed clamping frame 16 is integrally connected to the top of the fixed frame 5.

[0021] Furthermore, the support frame 2 forms a sliding structure through the movable rod 3, and the movable rod 3 forms a fixed structure with the cylinder 4. The support frame 2 forms a fixed structure with the movable rod 3 through the threaded rod 17, which satisfies the forward and backward movement and fixation of the cylinder 4 and plays an auxiliary role in the clamping operation.

[0022] Furthermore, the cylinder 4 forms a movable structure with the piston rod 8 and the wedge block 9, and the groove 6 forms a sliding structure with the slider 7. The slider 7 and the wedge block 9 form a fixed structure, thereby driving the wedge block 9 to move back and forth under the action of the piston rod 8.

[0023] Furthermore, the wedge block 9 is in close contact with the roller 10, and the roller 10 forms a tension structure with the tension spring 12 through the fixed shaft 11, so that the roller 10 moves while the wedge block 9 moves.

[0024] Furthermore, the roller 10 forms a rotating structure with the pin 14 via the movable frame 13, and the movable clamping frame 15 forms a rotating structure with the fixed frame 5 via the movable frame 13, thereby realizing the closure of the movable clamping frame 15 and the fixed clamping frame 16.

[0025] Working principle: In use, first, take out the threaded rod 17. Move the movable rod 3 inside the support frame 2, and at the same time move the cylinder 4 which is fixedly connected to it back and forth. When it moves to the appropriate position, thread the threaded rod 17 and the movable rod 3 are threadedly connected through the support frame 2 to fix the movable rod 3. This makes it convenient for the user to adjust and fix it back and forth, improving processing efficiency. By pressurizing the cylinder 4, the piston rod 8 moves the wedge block 9 down together, thereby opening the movable clamping frame 15. When the cylinder 4 is depressurized, the piston rod 8 lifts the wedge block 9, causing the movable frame 13 to move, realizing the closure of the movable clamping frame 15 and the fixed clamping frame 16, clamping the camshaft, making it convenient for the user to clamp the camshaft and enhancing the convenience of processing.
