[0002] A waterjet cutting fixture is a tool that uses water jet technology for cutting. It can cut materials such as metal, stone, and ceramics by using a mixture of high-pressure water jets and abrasives. Waterjet cutting fixtures are typically used for cutting materials.

[0003] In existing technology, the material block is placed on the fixture body, and the pressure plate is pressed against the fixture body by rotating the threaded rod, thus fixing the fixture body on the worktable and stabilizing the material block during cutting.

[0004] However, in actual use, the operator needs to press down the pressure plate through the threaded connection between the threaded rod and the pressure plate. But when rust appears on the surface of the threaded rod, it will cause the threaded rod to jam when rotating, which makes it inconvenient for the operator to use. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a waterjet cutting fixture with a positioning mechanism. This solves the problem that in actual use, workers need to press down the pressure plate through the threaded connection between the threaded rod and the pressure plate. However, when rust appears on the surface of the threaded rod, it can cause the threaded rod to jam during rotation, making it inconvenient for workers to use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waterjet cutting fixture with a positioning mechanism, comprising a worktable, a support plate fixedly connected to the top of the worktable, a fixture body mounted on the top of the support plate, a material block mounted on the top of the fixture body, a movable plate attached to the top of the worktable, a positioning structure mounted on the bottom of the movable plate, and a fixing structure mounted on the top of the movable plate.

[0019] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] In actual use, the operator needs to press down the pressure plate through the threaded connection between the threaded rod and the pressure plate. However, when rust appears on the surface of the threaded rod, it will cause the threaded rod to jam when rotating, which will make it inconvenient for the operator to use.

[0021] In view of this, the present invention provides a waterjet cutting fixture with a positioning mechanism, which solves the problem that in actual use, the operator needs to press down the pressure plate through the threaded connection between the threaded rod and the pressure plate. However, when rust appears on the surface of the threaded rod, it will cause the threaded rod to jam when rotating, which makes it inconvenient for the operator to use.

[0022] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0023] Example 1: By Figure 1-4It is known that a waterjet cutting fixture with a positioning mechanism includes a worktable 1, a support plate 11 fixedly connected to the top of the worktable 1, a fixture body 12 mounted on the top of the support plate 11, a material block 13 mounted on the top of the fixture body 12, a movable plate 15 attached to the top of the worktable 1, a positioning structure 3 mounted on the bottom of the movable plate 15, and a fixing structure 2 mounted on the top of the movable plate 15. The fixing structure 2 includes: a fixing shell 21, fixedly connected to the top of the movable plate 15 by bolts; a pressure plate 22, pressed against the top of the fixture body 12 and movably connected to the outer wall of the fixing shell 21; and a rack 23, fixedly connected to the pressure plate 21. Plate 22 extends to one end inside the fixed housing 21; ratchet 24 is rotatably connected to the inner wall of the fixed housing 21 via bearings and is frontally engaged with the front of rack 23. Several locking pins are provided on the front of ratchet 24, which can engage with the outer wall of rack 23; lever 25 is fixedly connected to the outer wall of ratchet 24 and movably connected to the inner wall of fixed housing 21; limiting structure 26 is installed on the top of ratchet 24; wherein, through the cooperation of fixed housing 21 and lever 25, ratchet 24 drives rack 23 to move, so that pressure plate 22 fixes tire body 12, and limiting structure 26 limits ratchet 24;

[0024] In the specific implementation process, it is worth noting that the tire body 12 is installed at the bottom of the material block 13, and the material of the tire body 12 is ceramic. Through the cooperation of the ratchet 24 and the limiting structure 26, the ratchet 24 is prevented from loosening. The tire body 12 is placed on the support plate 11, and with the cooperation of the limiting structure 26, the fixing shell 21 is pressed against the outer wall of the tire body 12. After it is fixed, the lever 25 is lifted to make the ratchet 24 rotate. Through the meshing of the ratchet 24 and the rack 23, the pressure plate 22 fixes the tire body 12. After it is fixed, the ratchet 24 will not loosen under the action of the limiting structure 26, ensuring that the pressure plate 22 fixes the tire body 12.

[0025] Furthermore, the limiting structure 26 includes: a locking block 261, which is engaged with the outer wall of the ratchet 24; a mounting shell 262, which is sleeved on the outer wall of the locking block 261 and fixedly connected to the top of the inner wall of the fixing shell 21 by bolts; a spring 263, which is disposed on the inner wall of the mounting shell 262 and abuts against the locking block 261 and the fixing shell 21; and a pull rod 264, which is inserted into the inner wall of the spring 263 and the inner wall of the fixing shell 21, and one end of which extends into the interior of the fixing shell 21 is fixedly connected to the top of the locking block 261; wherein, through the cooperation of the spring 263 and the mounting shell 262, the pull rod 264 drives the locking block 261 to move;

[0026] In the specific implementation process, it is worth noting that the mounting shell 262 is used to fix and limit the spring 263, so that the spring 263 is stable when it is compressed. When the pressure plate 22 is separated from the tire body 12, the pull rod 264 is pulled, which drives the locking block 261 to compress the spring 263, so that the locking block 261 is separated from the ratchet 24, ensuring that the ratchet 24 can rotate in the opposite direction to separate the pressure plate 22 from the tire body 12.

[0027] Furthermore, a water collection tank 14 is provided on the top of the workbench 1, and a water flow hole 16 is provided at the bottom of the water collection tank 14.

[0028] In the specific implementation process, it is worth noting that when the material block 13 is cut, excess water enters the water collection tank 14 and is discharged through the water outlet 16 to avoid water accumulation in the workbench 1 and affecting the use of the parts in the workbench 1.

[0029] Specifically, when using the waterjet cutting fixture with a positioning mechanism, when cutting the material block 13, the fixture body 12 is placed on the support plate 11, and under the action of the positioning structure 3, the fixing shell 21 is pressed against the outer wall of the fixture body 12, clamping the fixture body 12. After clamping, the lever 25 is lifted upward, driving the ratchet 24 to rotate. Through the engagement of the ratchet 24 and the rack 23, the pressure plate 22 fixes the fixture body 12. After fixing, the ratchet 24 is in the limiting structure 2. Under the action of 6, it will not loosen, ensuring that the pressure plate 22 is fixed to the tire body 12. When disassembling, pull the pull rod 264, which will cause the locking block 261 to squeeze the spring 263 and separate the locking block 261 from the ratchet 24. After the reset is completed, the locking block 261 is locked on the outer wall of the ratchet 24 under the action of the spring 263. When the ratchet 24 rotates normally, the tooth surface of the ratchet 24 is sloped, so that the ratchet 24 can rotate normally and avoid reverse rotation.

[0030] Example 2: From Figure 1-4 As can be seen, the positioning structure 3 includes: a movable block 31, which is fixedly connected to the bottom of the movable plate 15 and movably connected to the top of the worktable 1; a slide rod 32, which is inserted into the inner wall of the movable block 31 and fixedly connected to the inner wall of the worktable 1; a return spring 33, which is sleeved on the outer wall of the slide rod 32 and abuts against the movable block 31 and the worktable 1; and a slider 34, which is fixedly connected to the bottom of the movable plate 15 and slidably engaged with the inner wall of the worktable 1. The movable block 31 drives the movable plate 15 to move through the cooperation of the slide rod 32 and the return spring 33, while the slider 34 ensures the stability of the movable block 31 during movement.

[0031] In the specific implementation process, it is worth noting that, with the cooperation of the moving block 31, the return spring 33 and the slider 34, after the tire body 12 is placed on the support plate 11, the moving block 31 moves towards the side closer to the support plate 11 under the compression of the return spring 33, and the slider 32 can ensure that the moving block 31 is stable when moving, so that the fixed shell 21 is pressed against the outer wall of the tire body 12 to position the material block 13, and the slider 32 can stabilize the return spring 33 when it is compressed;

[0032] Furthermore, a limiting plate 17 is fixedly connected to the top of the support plate 11, and the top of the limiting plate 17 is inserted into the bottom of the tire body 12.

[0033] In the specific implementation process, it is worth noting that the limiting plate 17 can ensure the stability of the tire body 12 during installation and facilitates installation.

[0034] Specifically, based on the above embodiment, after the limiting plate 17 is inserted into the bottom of the tire body 12, the fixed shell 21, under the action of the return spring 33, causes the moving block 31 to move on the outer wall of the slide rod 32. When the return spring 33 is compressed, the slide rod 32 can ensure that it is stable when compressed and will not deviate. It can also ensure that the moving block 31 is stable when moving, thus positioning the tire body 12.
