Detailed Implementation

[0026] The technical solutions of the embodiments 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 protection scope of this utility model.

[0027] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides an embodiment of a high-precision multi-functional metal machining fixture, comprising a support plate 1, a support frame 2 fixedly connected to the upper surface of the support plate 1, a first motor 3 fixedly connected to the upper surface of the support frame 2, a first lead screw 4 fixedly mounted at the output end of the first motor 3, a first connecting plate 5 threadedly connected to the outer wall of the first lead screw 4, a sleeve 6 fixedly connected inside the first connecting plate 5, a fixed rod 7 slidably connected inside the sleeve 6, a movable plate 8 fixedly connected to the outer wall of the first connecting plate 5, and a first... A first fixed box 9 has a fixed plate 10 fixedly connected to its outer wall, and a second fixed box 11 fixedly connected to its inner wall. A damping column 12 is rotatably connected inside one side of the second fixed box 11, and a second lead screw 13 is rotatably connected inside the other side of the second fixed box 11. A rack plate 14 is threadedly connected to the outer wall of the second lead screw 13, and a handle 16 is fixedly connected to the outer wall of the second lead screw 13. A first gear 15 is meshed with the tooth end of the rack plate 14. A clamping assembly is provided on the outer wall of the first fixed box 9 for clamping materials.

[0028] Specifically, by starting the first motor 3 to drive the first lead screw 4 to rotate, the first connecting plate 5 and the sleeve 6 slide up and down, thereby driving the moving plate 8, the first fixed box 9, the fixed plate 10, and the second fixed box 11 to slide up and down. The support plate 1 fixes the support frame 2, ensuring that the position of the support frame 2 and other components does not change. When the first lead screw 4 rotates, its threaded connection with the first connecting plate 5 allows the first connecting plate 5 to slide linearly along the outer wall of the lead screw 4. Simultaneously, the sleeve 6 and the fixed rod 7 ensure that the first connecting plate 5 does not rotate during sliding. This is achieved by adjusting the clamp... The height of the workpiece is adjusted to accommodate various workpiece specifications. By rotating the handle 16, the second lead screw 13 is rotated, which in turn drives the rack plate 14 to slide. Through the meshing of the rack plate 14 and the first gear 15, the rack plate 14 drives the first gear 15 to rotate when sliding. The second fixing box 11 restricts the second lead screw 13, limiting it to rotate only inside the second fixing box 11 and preventing it from falling off during rotation. This allows for adjustment of the angle of the metal workpiece, improving its versatility. The outer wall of the first fixing box 9 is provided with a clamping assembly for clamping materials.

[0029] Reference Figure 1 and Figure 5 The clamping assembly includes a second motor 17. The outer wall of the second motor 17 is fixedly disposed on the outer wall of the first fixed box 9. A vertical shaft 20 is fixedly disposed on the output end of the second motor 17. A second gear 19 is fixedly connected to the outer wall of the vertical shaft 20. A rack block 18 is meshed with the tooth end of the second gear 19. A connecting block 21 is fixedly connected to the outer wall of the rack block 18. The outer wall of the fixing plate 10 is fixedly connected to the outer wall of the connecting block 21. A clamping block 22 is rotatably connected inside the second fixed box 11.

[0030] Specifically, the second motor 17 is started to drive the vertical shaft 20 to rotate, thereby causing the second gear 19 to rotate. When the second gear 19 rotates, the meshing action between the second gear 19 and the rack block 18 causes the rack block 18 to slide, thereby driving the connecting block 21, the fixing plate 10, the second fixing box 11 and the clamping block 22 to slide, so that the clamping blocks 22 on both sides clamp the metal workpiece. The second gear 19 is fixed to the outer wall of the vertical shaft 20, so that when the vertical shaft 20 rotates, the second gear 19 rotates synchronously along the central axis of the vertical shaft 20.

[0031] Reference Figure 2 The outer wall of the first lead screw 4 is rotatably connected to the inside of the support plate 1, and the outer wall of the first connecting plate 5 slides on the inner wall of the support frame 2;

[0032] Specifically, the first lead screw 4 rotates inside the support plate 1 to prevent the position of the first lead screw 4 from changing during rotation. When the first connecting plate 5 slides, the outer wall of the first connecting plate 5 is attached to the inner wall of the support frame 2 to prevent the first connecting plate 5 from rotating and to improve the stability during sliding.

[0033] Reference Figure 2 The outer wall of the fixing rod 7 is fixedly connected to the inside of the support plate 1, and the outer wall of the fixing rod 7 is fixedly connected to the inside of the support frame 2;

[0034] Specifically, the support plate 1 and the support frame 2 fix the fixed rod 7, preventing the fixed rod 7 from falling off under force when the sleeve 6 slides on the outer wall of the fixed rod 7.

[0035] Reference Figure 4 The outer wall of the rack plate 14 slides on the inner wall of the second fixed box 11, and the outer wall of the first gear 15 is rotatably connected to the inside of the second fixed box 11.

[0036] Specifically, when the rack plate 14 slides, its outer wall is attached to the inner wall of the second fixed box 11 to prevent the rack plate 14 from rotating. The second fixed box 11 provides rotational support for the first gear 15 to prevent the tooth tip of the first gear 15 from disengaging from the rack plate 14 and causing it to stop when rotating.

[0037] Reference Figure 5 The outer wall of the rack block 18 slides on the inner wall of the moving plate 8, the outer wall of the vertical shaft 20 is rotatably connected to the inside of the first fixed box 9, the outer wall of the clamping block 22 is fixedly connected to the outer wall of the damping column 12, and the outer wall of the other clamping block 22 is fixedly connected to the outer wall of the first gear 15.

[0038] Specifically, the rack block 18 is attached to the inner wall of the moving plate 8 when sliding to prevent instability during sliding. The first fixed box 9 provides rotational support for the vertical shaft 20. Due to the friction of the damping column 12, it works in conjunction with the clamping block 22 on the other side and the first gear 15 to enable the clamping blocks 22 on both sides to rotate synchronously when the workpiece is clamped.

[0039] Reference Figure 1 and Figure 6 A slide rail 23 is fixedly connected to the lower surface of the support plate 1. A moving block 24 is slidably connected to the outer wall of the slide rail 23. An X-shaped bracket 25 is rotatably connected to the inner wall of the moving block 24. A fixed block 26 is rotatably connected to the outer wall of the X-shaped bracket 25. A base 27 is fixedly connected to the lower surface of the slide rail 23 on the other side. A hydraulic cylinder 28 is fixedly connected to the outer wall of the base 27. A second connecting plate 29 is fixedly installed at the output end of the hydraulic cylinder 28. The lower surface of the fixed block 26 is fixedly connected to the upper surface of the base 27. The outer wall of the second connecting plate 29 is fixedly connected to the outer wall of the moving block 24.

[0040] Specifically, by activating the hydraulic cylinder 28 to push the second connecting plate 29, the movable blocks 24 fixed on both sides of the second connecting plate 29 slide against the base 27 on the outer wall of the slide rail 23, thereby causing the X-shaped bracket 25 to rotate on the inner wall of the movable blocks 24 and the fixed blocks 26 connected at the four ends, and thus causing the X-shaped bracket 25 to retract. The slide rail 23 guides the movable blocks 24, so that the movable blocks 24 can only move linearly along the outer wall of the slide rail 23. The second connecting plate 29 keeps the movable blocks 24 on both sides sliding synchronously, thereby raising the position of the support plate 1 and the clamping block 22, achieving the effect of conveniently picking up metal workpieces.

[0041] Working principle: When processing metal workpieces of different heights, the first motor 3 on the upper surface of the support frame 2 drives the first lead screw 4 to rotate, causing the first connecting plate 5 and sleeve 6 to slide up and down on the inner wall of the support frame 2 and the outer wall of the fixed rod 7. This causes the moving plate 8, the first fixed box 9, the fixed plate 10 and the second fixed box 11 to slide up and down, thereby causing the clamping block 22 to slide up and down to adjust the clamping height. After adjusting to a suitable clamping height, the metal workpiece is placed between the upper surface of the support plate 1 and the clamping blocks 22 on both sides. Then, the second motor 17 is started to drive the vertical shaft 20 to rotate, thereby causing the second gear 19 fixed on the outer wall of the vertical shaft 20 to rotate. When the second gear 19 rotates, the meshing action between the second gear 19 and the rack block 18 causes the rack block 18 to slide on the inner wall of the first fixed box 9, thereby causing the connecting block 21, the fixed plate 10, the second fixed box 11 and the clamping block 22 to slide, so that the clamping blocks 22 on both sides clamp the metal workpiece. By adjusting the height of the clamping block 22, the effect of adapting to workpieces of various specifications can be achieved.

[0042] When the machining position of the metal workpiece needs to be adjusted, the second lead screw 13 is rotated by turning the handle 16, which in turn drives the rack plate 14 to slide. Through the meshing action of the rack plate 14 and the first gear 15, the rack plate 14 drives the first gear 15 to rotate when sliding, which in turn causes the clamping block 22 to rotate and drives the damping column 12 and the clamping block 22 on the other side to rotate, thereby adjusting the angle of the metal workpiece. This achieves the effect of improving versatility. By cooperating with the moving plate 8, the machining angle of the metal workpiece can be adjusted after clamping it, which can avoid frequent adjustment of the fixture in the operation of metal workpieces that require multi-face machining, thereby achieving the effect of improving production efficiency.

[0043] During loading and unloading, the hydraulic cylinder 28 is activated to push the second connecting plate 29, causing the movable blocks 24 fixed on both sides of the second connecting plate 29 to slide against the base 27 on the outer wall of the slide rail 23. This causes the X-shaped bracket 25 to rotate on the inner wall of the movable blocks 24 and fixed blocks 26 connected at four ends, thereby causing the X-shaped bracket 25 to retract and raise the position of the support plate 1 and the clamping block 22, achieving the effect of conveniently picking up metal workpieces.

[0044] In other words, this machining fixture not only achieves the effects of adapting to workpieces of various specifications, improving versatility and production efficiency, but also facilitates the handling of metal workpieces.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
