Description

Technical Field

[0001] This utility model relates to the field of die casting clamping technology, specifically a clamping fixture for magnesium-aluminum alloy die castings. Background Technology

[0002] Magnesium-aluminum alloy die castings are parts manufactured through a die casting process. Their main components are magnesium and aluminum. Clamping fixtures for magnesium-aluminum alloy die castings are equipment or tools specifically designed to fix and support magnesium-aluminum alloy die castings, ensuring the stability and accuracy of the parts during processing, assembly, or inspection.

[0003] The patent document with announcement number CN216326707U describes a clamping device for magnesium-aluminum alloy die castings. The described solution uses a drive motor to drive two clamping seats to move closer together to achieve clamping. During clamping, the die casting limiting rod on the clamping seat can be inserted into the hole punched in the magnesium-aluminum alloy die casting, making the fixation more secure. Moreover, the die casting limiting rod is elastically connected by a spring, which can maximize the protection of the magnesium-aluminum alloy die casting and prevent damage to it.

[0004] The above case has the problem of not being able to adjust the clamping seat. Since the shapes and sizes of magnesium-aluminum alloy die castings vary, adjustments need to be made according to the actual size when clamping them in order to clamp magnesium-aluminum alloy die castings of different shapes. However, this device cannot be adjusted, which has certain limitations and cannot be adapted to some magnesium-aluminum alloy die castings. Utility Model Content

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] In one embodiment, such as Figures 1-3 As shown, a clamping fixture for a magnesium-aluminum alloy die-casting part includes: a support plate 100, a concave plate 200, and a clamping assembly. The concave plate 200 is disposed on the top of the support plate 100. The clamping assembly includes a first motor 301, which is disposed on one side of the concave plate 200. The output end of the first motor 301 is provided with a bidirectional lead screw 302, which is rotatably connected to the inside of the concave plate 200. A slider is also slidably connected inside the concave plate 200. 2. Both ends of the slider are threaded into the inside of the slider. The top of the slider is fixedly connected to a first clamping block 303. The first clamping block 303 is slidably connected to a second clamping block 304. The first clamping block 303 is provided with an adjustment component for adjusting the second clamping block 304. By starting the first motor 301, it drives the bidirectional lead screw 302 to rotate, thereby driving the two sliders to slide inside the concave plate 200, thereby driving the two second clamping blocks 304 to move closer or further apart.

[0027] In one embodiment, such as Figure 1 and Figure 3 As shown, the adjusting assembly includes a locking nut 401, which is threaded to both sides of the upper part of the first clamping block 303. The second clamping block 304 has sliding grooves 402 on both sides, and one end of the locking nut 401 is located in the sliding groove 402. By rotating the locking nut 401, it is moved away from the sliding groove 402, so that the second clamping block 304 can slide inside the first clamping block 303.

[0028] In one embodiment, such as Figure 1 and Figure 2 As shown, both sides of the concave plate 200 are provided with heat dissipation components for cooling the magnesium-aluminum alloy die-casting machine. The heat dissipation components include several fans 501, which are located at both ends of both sides of the concave plate 200. The output ends of the fans 501 are located inside the concave plate 200. Several ventilation holes 502 are opened on the top of the concave plate 200. By starting the fans 501, air is blown into the concave plate 200 through the output ends and then discharged through the ventilation holes 502, thereby cooling the magnesium-aluminum die-casting parts.

[0029] In one embodiment, such as Figure 2 As shown, the bottom of the support plate 100 is provided with a rotating assembly for rotating the concave plate 200. The rotating assembly includes a support frame 601, which is fixedly connected to the bottom of the support plate 100. The bottom of the support frame 601 is provided with a second motor 602. The output end of the second motor 602 is provided with a first rotating gear 603. The first rotating gear 603 meshes with a second rotating gear 604. The second rotating gear 604 has a rotating column inside. The bottom of the rotating column is rotatably connected to the inside of the support frame 601. The top of the rotating column passes through the support plate 100 and is fixedly connected to the concave plate 200. By starting the second motor 602, it drives the first rotating gear 603 to rotate, which in turn drives the second rotating gear 604 and the rotating column to rotate, thereby causing the concave plate 200 to rotate on the surface of the support plate 100.

[0030] In one embodiment, such as Figure 1 As shown, the bottom of the support plate 100 is also provided with a lifting assembly for raising and lowering the support plate 100. The lifting assembly includes a plurality of telescopic columns 701, the telescopic ends of the plurality of telescopic columns 701 are fixedly connected to the bottom of the support plate 100, a support bar is provided between the telescopic columns 701, an electric telescopic rod 702 is installed on the support bar, and the output end of the electric telescopic rod 702 is fixedly connected to the bottom of the support plate 100. By activating the electric telescopic rod 702, the support plate 100 is raised and lowered.

[0031] In one embodiment, such as Figure 1 and Figure 3 As shown, protective pads are provided on the sides of the two second clamping blocks 304 that are close to each other to prevent damage to the magnesium-aluminum die-casting parts during clamping.

[0032] In one embodiment, such as Figure 2 As shown, the concave plate 200 has a hollow structure, which facilitates the air blown out by the fan 501 to pass through the ventilation hole 502.

[0033] In one embodiment, such as Figure 1 and Figure 3 As shown, the end of the locking nut 401 away from the slide groove 402 is hexagonal, which facilitates the rotation of the locking nut 401.

[0034] The above embodiment discloses a clamping fixture for magnesium-aluminum alloy die castings. The magnesium-aluminum die casting is placed on top of a concave plate 200. Then, a fan 501 is activated to blow air into the concave plate 200 through its output end, which is then discharged through a ventilation hole 502, thereby cooling the magnesium-aluminum die casting. The second clamping block 304 is then adjusted according to the size of the magnesium-aluminum die casting. By rotating the locking nut 401, it is moved away from the slide groove 402, allowing the second clamping block 304 to slide inside the first clamping block 303. After sliding to a suitable height, the locking nut 401 is rotated again to bring it closer to the inside of the slide groove 402, increasing friction and thus fixing the second clamping block 304. Finally, the first motor 301 is activated... It drives the bidirectional lead screw 302 to rotate, thereby causing the two sliders to slide inside the concave plate 200, which in turn causes the two second clamping blocks 304 to move closer together, thus clamping the magnesium-aluminum die-casting. Then, it is adjusted according to the height of the operator. By activating the electric telescopic rod 702, it drives the support plate 100 to rise and fall, so that the concave plate 200 reaches a suitable operating height, and then the magnesium-aluminum die-casting can be operated. Alternatively, the second motor 602 can be activated to drive the first rotating gear 603 to rotate, which in turn drives the second rotating gear 604 and the rotating column to rotate, thereby causing the concave plate 200 to rotate on the surface of the support plate 100, and thus causing the magnesium-aluminum die-casting to rotate, so that it can be operated in multiple ways.

[0035] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
