[0002] Magnesium alloy products generally refer to various tools, parts and equipment made of metal materials. These products are widely used in daily life, industrial production, construction and other fields. Magnesium alloy products usually require clamps for clamping during processing.

[0003] Existing fixtures typically place magnesium alloy products horizontally on a jig and clamp them by abutting the sides of the product. This lack of internal clamping makes it difficult to achieve high-precision machining positioning and is unsuitable for magnesium alloy products requiring vertical machining. For example, the "Quick-locking Hardware Fixture" disclosed in patent document "CN218836866U" uses an L-shaped clamp to hold the horizontally placed magnesium alloy product, which can only clamp the sides of the product for fixation. This is insufficient for higher precision requirements and is also unsuitable for magnesium alloy products requiring vertical machining. Utility Model Content

Frame Detailed Implementation

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Please refer to Figure 1-5 ;

[0025] The workpiece targeted by this fixture has a connecting hole, and a slot is provided on one side of the workpiece.

[0026] Example 1:

[0027] A fixture for machining magnesium alloy products in a vertical direction includes a support plate 1 and a drive cylinder 2. The support plate 1 is arranged vertically, and the drive cylinder 2 is installed horizontally on one side of the support plate 1. Positioning plate 1 has a first positioning plate 3 and a second positioning plate 4 at both ends. The first positioning plate 3 has a slot 5 facing the second positioning plate 4, and the second positioning plate 4 has a slot 6 facing the first positioning plate 3. The support plate 1 has a through shaft hole. The piston shaft of the drive cylinder 2 is provided with a pull core 7. The piston shaft of the drive cylinder 2 is detachably connected to the pull core 7. The pull core 7 passes through the through shaft hole and can be used to fix the workpiece. The support plate 1 is also provided with a limit block 8. The first positioning plate 3, the second positioning plate 4, and the limit block 8 form a space for accommodating the workpiece. The support plate 1 is also provided with an opening and closing component for opening or closing the space.

[0028] Specifically, when the operator needs to use this fixture to clamp the workpiece, the first step is to ensure that the space for accommodating the workpiece is in the open state. The operator needs to insert the workpiece into the space, that is, slide one side of the workpiece with positioning plate 3 and the other side of the workpiece with positioning plate 4, so that the workpiece is inserted into slot 5 and slot 6. The second step is to extend the piston shaft of the drive cylinder 2 so that the pull core 7 passes through the connecting hole and abuts against the hole wall of the connecting hole, further fixing the workpiece from the inside. Since the support plate 1 is vertically set, the workpiece can be vertically clamped on the support plate 1. That is, the piston shaft of the drive cylinder 2 pushes the pull core 7 to extend out of the hole wall of the connecting hole that fills the workpiece to complete the fixation of the workpiece from the inside. The positioning plate 3, positioning plate 4 and limiting block 8 on the vertically set support plate 1 form a space for vertically positioning the workpiece, so that the workpiece can be kept fixed in the vertical direction. The third step is to close the space by opening and closing the opening and closing device to further improve the stability of the workpiece on this fixture.

[0029] In some embodiments, the support plate 1 is provided with a through groove 9 in the vertical direction, and the opening and closing element is located in the through groove 9. The opening and closing element includes a first spring 10, a second spring 11, and a sliding block 12. The first spring 10 and the second spring 11 are arranged in the horizontal direction. One end of the first spring 10 is fixedly connected to the bottom of the through groove 9, and the other end of the first spring 10 is fixedly connected to the sliding block 12. One end of the second spring 11 is fixedly connected to the bottom of the through groove 9, and the other end of the second spring 11 is fixedly connected to the sliding block 12.

[0030] Specifically, when a workpiece needs to be inserted into the space that accommodates it, the operator can press the sliding block 12 to compress the spring 10 and the spring 2 11, causing the sliding block 12 to fully enter the through groove 9, thereby opening the space formed by the positioning plate 1 3, the positioning plate 2 4, and the limiting block 8. When the workpiece is inserted into the space, the operator can release the pressed sliding block 12, releasing the elasticity of the spring 10 and the spring 2 11, allowing them to extend freely. This causes the sliding block 12 to close the space formed by the positioning plate 1 3, the positioning plate 2 4, and the limiting block 8, further fixing the workpiece on the support plate 1.

[0031] In some embodiments, a first cylinder (not shown in the figure) and a second cylinder (not shown in the figure) are provided on the bottom of the through groove 9. A first spring 10 is located inside the first cylinder, and a second spring 11 is located inside the second cylinder. One end of the first cylinder is fixedly connected to the bottom of the through groove 9, and one end of the second cylinder is fixedly connected to the bottom of the through groove 9. Furthermore, a fixing plate 13 is provided on the bottom of the through groove 9, and the fixing plate 13 forms a gap with the wall of the through groove 9. A sliding block 12 is located in the gap, and the sliding block 12 is slidably connected to the wall of the through groove 9 and the fixing plate 13. The sliding block 12 is provided with a toggle post 14, and the toggle post 14 is fixedly connected to the sliding block 12.

[0032] Specifically, when the operator needs to use the opening and closing mechanism to close the space formed by the positioning plate 3, the positioning plate 4 and the limiting block 8, the operator can move the sliding block down by using the toggle post 14, so that the sliding block enters the through groove 9, thereby facilitating the insertion of the workpiece into the space. Afterwards, the operator can release the toggle post 14, so that the elastic force of the spring 10 and the spring 21 is released, so that the spring 10 and the spring 21 are in a free extension state, thereby causing the sliding block 12 to close the space formed by the positioning plate 3, the positioning plate 4 and the limiting block 8.

[0033] In some embodiments, the support plate 1 is provided with a slider 15, which is slidably connected to the support plate 1 and is used to engage with the workpiece in a slot.

[0034] Specifically, after the workpiece is inserted into the space, the operator can slide the slider 15 to engage with the workpiece's slot, thereby further fixing the workpiece.

[0035] Example 2:

[0036] This embodiment has a structure that is largely the same as that of Embodiment 1;

[0037] The structural difference between this embodiment and Embodiment 1 is:

[0038] In this embodiment, the support plate 1 is provided with two reinforcing ribs 16, which are located on both sides of the drive cylinder 2. The reinforcing ribs 16 are provided with a worktable 17, and the upper surface of the worktable 17 is fixedly connected to the bottom of the reinforcing ribs 16.

[0039] Example 3:

[0040] This embodiment has a structure that is largely the same as that of Embodiment 2;

[0041] The structural difference between this embodiment and Embodiment 2 is:

[0042] In this embodiment, a rotating assembly is provided under the worktable 17. The rotating assembly is used to rotate the worktable 17. Specifically, the rotating assembly includes a drive component 18, a worm gear, a rotating shaft 19, and a frame 20. The frame 20 is fixedly connected to the lower surface of the worktable 17. The drive component 18 is used to drive the rotating shaft 19 to rotate. The rotating shaft 19 passes through the frame 20 and is rotatably connected to the frame 20. The worm gear is sleeved on the rotating shaft 19 and meshes with the worm gear. The worm gear is fixedly provided with a second rotating shaft, which is coaxially connected to the worm gear. The second rotating shaft is set in the vertical direction and is fixedly connected to the worktable 17. More specifically, the drive component 18 drives the rotating shaft 19 to rotate, the rotation of the rotating shaft 19 drives the worm gear to rotate, the worm gear meshes with the worm gear, and the rotation of the worm gear causes the second rotating shaft to rotate, thereby driving the worktable 17 to rotate.
