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.

[0019] Please refer to Figure 1-3 As shown, this utility model provides a drilling fixture for processing explosion-proof wave valves, including a limiting box 1 and a clamping block 2. The bottom of the limiting box 1 is provided with a drilling position 11. A sliding rod 9 is connected to one side of the limiting box 1. Two sets of sliding rods 9 are provided. One end of the sliding rod 9 passes through the clamping block 2 and is connected to an adjustment component. A clamping mechanism is provided at the lower end of the clamping block 2. Two sets of sliding grooves 10 are provided on the upper surface of the limiting box 1. An arc-shaped sliding plate 17 is slidably installed inside the sliding groove 10. A clamping device is provided at the upper end of the arc-shaped sliding plate 17.

[0020] Specifically, by rotating the knob 15, the bidirectional screw 14 is rotated. The rotation of the bidirectional screw 14 can cause the two sets of second clamping plates 4 to tighten inward, and at the same time, it can cause the slider 12 to slide inside the arc-shaped slide plate 17, thereby clamping the drilling tool. Then, pressing the drilling tool can cause the arc-shaped slide plate 17 to slide in the slide groove 10, thereby drilling the explosion-proof valve. In conjunction with the drilling position 11, the drilling accuracy is greatly improved.

[0021] The clamping device includes a slider 12, a second clamping plate 4, a connecting plate 13, a bidirectional screw 14, and a knob 15. The slider 12 is slidably disposed inside the upper end of the arc-shaped sliding plate 17. One end of the slider 12 is connected to the surface of one side of the second clamping plate 4. Two sets of second clamping plates 4 are provided, and the surface of one side of each set of second clamping plates 4 is connected to the connecting plate 13. Both ends of the bidirectional screw 14 pass through the two sets of connecting plates 13. The knob 15 is connected to one end of the bidirectional screw 14 and is disposed on one side of one set of connecting plates 13. By rotating the knob 15, the bidirectional screw 14 is driven to rotate. The rotation of the bidirectional screw 14 can drive the two sets of second clamping plates 4 to tighten inward, and at the same time drive the slider 12 to slide inside the arc-shaped sliding plate 17, thereby clamping the drilling tool. Then, pressing the drilling tool can drive the arc-shaped sliding plate 17 to slide in the slide groove 10, thereby drilling the explosion-proof valve.

[0022] The adjustment component includes a first baffle 5 and a second threaded rod 18. The first baffle 5 is installed at one end of the two sets of sliding rods 9 and is located on one side of the clamping block 2. The second threaded rod 18 is threadedly connected inside the first baffle 5. One end of the second threaded rod 18 is connected to a rotating block. By rotating the second threaded rod 18, the first baffle 5 is moved to one side. The movement of the first baffle 5 pulls the sliding rods 9 to slide inside the clamping block 2, thereby causing the limiting box 1 to move accordingly. This allows the drilling position to be adjusted, facilitating drilling at different positions.

[0023] The clamping mechanism includes a slide rod 6, a first threaded rod 7, a turntable 8, and a first clamping plate 3. The clamping block 2 is located at the lower end of the clamping block 2. The first threaded rod 7 is threadedly connected to the inside of the first clamping plate 3, with one end rotatably mounted on the surface of the clamping block 2. The turntable 8 is mounted on the other end of the first threaded rod 7. Two sets of slide rods 6 are provided and located on both sides of the first threaded rod 7. One end of the slide rod 6 is mounted on the surface of the clamping block 2, and the other end passes through the first clamping plate 3 and is connected to a stop block. The first clamping plate 3 can slide on the surface of the slide rod 6. By rotating the turntable 8, the first threaded rod 7 is driven to rotate. By rotating the first threaded rod 7, the first clamping plate 3 is driven to slide on the surface of the slide rod 6 and move inward, thus fixing it to one side of the explosion-proof wave valve.

[0024] Among them: a second baffle 16 is installed at one end of each of the two sets of sliders 12, and a limit plate is installed on the lower surface of the two sets of arc-shaped slide plates 17. The limit plate is set inside the limit box 1. The second baffle 16 can limit the slider 12 and prevent it from slipping. The limit plate installed on the lower surface of the arc-shaped slide plate 17 can limit the arc-shaped slide plate 17.

[0025] Among them, the upper surface of the limit box 1 is provided with a hole, and two sets of sliding grooves 10 are provided on both sides of the hole. The hole facilitates the movement of drilling tools and also facilitates drilling of the explosion-proof valve.

[0026] Working Principle: This utility model is a drilling fixture for processing blast-proof valves. First, rotating the turntable 8 drives the first threaded rod 7 to rotate. The rotation of the first threaded rod 7 drives the first clamping plate 3 to slide on the surface of the slide rod 6 and move inward, fixing it to one side of the blast-proof valve. Then, rotating the second threaded rod 18 drives the first baffle 5 to move to one side. The movement of the first baffle 5 pulls the slide rod 9 to slide inside the clamping block 2, thereby driving the limit box 1 to move accordingly, thus adjusting the drilling position. Then, the drilling tool is placed inside the second clamping plate 4, so that the drill bit is placed inside the drilling position 11. Then, rotating the knob 15 drives the bidirectional screw 14 to rotate. The rotation of the bidirectional screw 14 drives the two sets of second clamping plates 4 to tighten inward, and at the same time drives the slider 12 to slide inside the arc-shaped slide plate 17, thereby clamping the drilling tool. Then, pressing the drilling tool drives the arc-shaped slide plate 17 to slide in the slide groove 10, thereby drilling the blast-proof valve.
