Description

Technical Field

[0001] This utility model belongs to the field of die casting technology, and specifically relates to a surface treatment device for magnesium alloy die castings. Background Technology

[0002] In modern manufacturing, magnesium alloy die castings are highly favored due to their unique advantages. Magnesium alloys, with their low density, high specific strength and specific stiffness, excellent shock absorption performance and strong electromagnetic shielding, have become ideal materials for achieving product lightweighting, performance enhancement and competitiveness in many fields such as automobiles, electronics, and aerospace. Through the die casting process, in which liquid magnesium alloy is rapidly filled into the mold cavity under high pressure and solidified under pressure, die castings with high dimensional accuracy, good surface quality and complex shapes can be produced, such as automobile engine blocks, transmission housings and electronic product shells.

[0003] To ensure the appearance and performance of magnesium alloy die castings, surface polishing is a crucial step. Existing technologies have been working to enhance the additional functions of polishing operations. For example, the surface treatment device for magnesium alloy die castings disclosed in Chinese Patent No. CN222078866U, utilizing components such as a second servo motor, fan blades, support feet, connecting holes, filter plates, and ventilation mesh, effectively cleans dust generated during processing, improves the working environment, and enhances the device's practicality. However, it is undeniable that such devices have a significant weakness in the core polishing stage. The fixed spacing of the grinding sleeves means that when faced with polishing requirements for magnesium alloy die castings of varying thicknesses, the height of the grinding sleeves cannot be flexibly adjusted to adapt to different workpieces. This greatly limits the equipment's versatility and processing efficiency, making it difficult to meet diverse and high-precision production requirements. Therefore, improvements to the existing technology are necessary. Utility Model Content

[0004] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a surface treatment device for magnesium alloy die castings to solve the problem of poor adaptability during the application of existing technologies.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A surface treatment device for magnesium alloy die castings includes a base, a collection frame fixedly installed on the top of the base, a polishing mechanism fixedly installed in the middle of the upper rear side of the collection frame, and a clamping mechanism fixedly installed in the upper front side of the collection frame. The inner side of the clamping mechanism holds the alloy part to be polished, and the alloy part to be polished is disposed inside the polishing mechanism.

[0007] The polishing mechanism includes a frame, which is fixedly installed in the middle of the back of the collection frame. Polishing components are movably installed at both ends of the inside of the frame. An adjustment component is fixedly installed on one side of the frame, and the adjustment end of the adjustment component is connected to the polishing component.

[0008] As a preferred technical solution, a collection drawer is slidably connected inside the collection frame, and a side plate is fixedly installed on the outside of the collection drawer extending out of the collection frame.

[0009] As a preferred technical solution, fixing plates are fixedly installed at both the upper and lower ends of both sides of the side plate, and a hand-tightening screw is threaded to the outer end of the fixing plate, and the hand-tightening screw is threaded to the collection frame.

[0010] As a preferred technical solution, the adjustment component includes a side rail, which is fixedly installed on one side of the frame. A lead screw is rotatably connected inside the side rail, and the two ends of the lead screw have opposite thread directions. A slider is threaded to both ends of the lead screw. A connecting arm is fixedly installed on the outside of the slider. The outside of the connecting arm is connected to the polishing component. A first motor is fixedly installed on the top of the side rail, and the bottom output end of the first motor is fixedly connected to the top of the lead screw.

[0011] As a preferred technical solution, the polishing assembly includes a movable block, which is slidably connected to the top and bottom of the frame. The outer side of the movable block is fixedly connected to the end of the connecting arm. A second motor is fixedly installed on the outer side of the movable block, and a polishing roller is fixedly installed through the movable block at the output end of the second motor.

[0012] As a preferred technical solution, the clamping mechanism includes a mounting sleeve, which is fixedly connected to the upper ends of both sides of the front of the collection frame. An electric push rod is fixedly installed on the inner side of the mounting sleeve. A bending connecting rod is fixedly installed at the output end of the electric push rod. A clamping assembly is fixedly installed at the outer end of the bending connecting rod. The bending connecting rod clamps and installs the alloy part to be polished through the clamping assembly.

[0013] As a preferred technical solution, the clamping assembly includes a concave seat, which is fixedly installed on the outer end of the bending connecting rod. An adjusting screw is threadedly connected to the top of the concave seat, and a clamping plate is rotatably connected to the bottom of the adjusting screw through the upper end of the concave seat. Support shafts are fixedly connected to both sides of the top of the clamping plate, and the top of the support shafts passes through the concave seat.

[0014] In summary, the present invention has the following main advantages:

[0015] First, by setting up a polishing mechanism, this device can effectively improve the adaptability and efficiency of polishing magnesium alloy die castings. During operation, the first motor is started, which drives the lead screw to rotate.

During operation, the casting is placed in the concave seat, and the adjusting screw is rotated to move the clamping plate down to clamp the casting. The support shaft ensures that the clamping plate moves smoothly. After clamping, the electric push rod is activated, which pushes the bending connecting rod to drive the casting to move laterally between the polishing rollers. By controlling the electric push rod, the top and bottom of the casting can be automatically and efficiently polished, improving the convenience and efficiency of polishing.

[0023] Example

[0024] refer to Figures 1 to 5The surface treatment device for magnesium alloy die castings in this embodiment includes a base 1, a collection frame 2 fixedly installed on the top of the base 1, a polishing mechanism 3 fixedly installed in the middle of the upper rear side of the collection frame 2, a clamping mechanism 5 fixedly installed in the upper front side of the collection frame 2, and an alloy part 4 to be polished clamped in the inner side of the clamping mechanism 5. The alloy part 4 to be polished is disposed in the inner side of the polishing mechanism 3.

[0025] The polishing mechanism 3 includes a frame 31, which is fixedly installed in the middle of the back of the collection frame 2. Polishing components 32 are movably installed at both ends of the frame 31. An adjustment component 33 is fixedly installed on one side of the frame 31. The adjustment end of the adjustment component 33 is connected to the polishing component 32. When this magnesium alloy die-casting surface treatment device is working, the base 1 provides stable support for the entire device. The alloy part 4 to be polished is fixed at the upper front of the collection frame 2 by the clamping mechanism 5 and is located inside the polishing mechanism 3. The frame 31 in the polishing mechanism 3 is fixed in the middle of the back of the collection frame 2. When the adjustment component 33 is activated, its adjustment end acts on the polishing components 32 movably installed at both ends of the frame 31 to adjust the position of the polishing component 32 so that the polishing component 32 can fit against the alloy part 4 to be polished. Then, the polishing component 32 starts to work and polishes the surface of the alloy part. Waste generated during the polishing process will fall into the collection frame 2 below. The whole process realizes the surface treatment operation of the magnesium alloy die-casting.

[0026] refer to Figures 1-3 A side plate 7 is fixedly installed on the outside of the collection drawer 6, extending from the outside of the collection frame 2. Fixing plates 8 are fixedly installed at both the top and bottom ends of both sides of the side plate 7. A hand-tightening screw 9 is threaded to the outer end of the fixing plate 8. The hand-tightening screw 9 is threadedly connected to the collection frame 2. In this device, the collection drawer 6 is fixed to the outside of the side plate 7, and fixing plates 8 are provided at both the top and bottom ends of both sides of the side plate 7. The hand-tightening screw 9 is threaded to the outer end of the fixing plate 8. When it is necessary to fix the collection drawer 6, the hand-tightening screw 9 is rotated. Because the hand-tightening screw 9 is threaded with the collection frame 2... The axial force generated by the connection and rotation causes the screw to gradually screw into the collection frame 2. During the screwing process, the screw drives the fixed plate 8 and side plate 7 connected to it to move towards the collection frame 2, thereby tightly abutting the collection drawer 6 against the collection frame 2, achieving a stable installation of the collection drawer 6. To remove the collection drawer 6, turn the hand-tightening screw 9 in the opposite direction to gradually unscrew it from the collection frame 2, releasing the fixation of the side plate 7 and the collection drawer 6, and then the collection drawer 6 can be pulled out of the collection frame 2 for easy cleaning of waste and other items inside the collection drawer 6.

[0027] refer to Figures 1-4The adjusting component 33 includes a side rail 331, which is fixedly installed on one side of the frame 31. A lead screw 332 is rotatably connected inside the side rail 331, with opposite thread directions at both ends of the lead screw 332. A slider 333 is threaded to both ends of the lead screw 332. A connecting arm 334 is fixedly installed on the outer side of the slider 333, and its outer side is connected to the polishing component 32. A first motor 335 is fixedly installed on the top of the side rail 331, and its bottom output end is fixedly connected to the top of the lead screw 332. The polishing component 32 includes a movable block 321, which is slidably connected to the top and bottom of the frame 31. The outer side of the movable block 321 is fixedly connected to the end of the connecting arm 334. A second motor 322 is fixedly installed on the outer side of the movable block 321, and its output end passes through the movable block 321 to fix a polishing roller 323. This magnesium alloy die-casting surface treatment device uses an adjustment component 33 and a polishing component 32 in combination. During use, the first motor 335 can be started, and its bottom output end drives the lead screw 332 to rotate in the side rail 331. Since the threads at both ends of the lead screw 332 turn in opposite directions, when the lead screw 332 rotates, it drives the slider 333 connected to the threads at both ends to make linear movements in opposite directions in the side rail 331. The slider 333 drives the movable block 321 connected to it to slide at the top and bottom of the frame 31 through the outer connecting arm 334, thereby adjusting the distance between the two movable blocks 321 and adjusting the position of the polishing component 32 to adapt to alloy parts 4 of different thicknesses to be polished. Then, the second motor 322 is started, and its output end drives the polishing roller 323 to rotate. The rotating polishing roller 323 contacts the surface of the alloy part 4 to be polished, completing the polishing treatment of the alloy part surface.

[0028] refer to Figures 1-3 and Figure 5The clamping mechanism 5 includes a mounting sleeve 51, which is fixedly connected to the upper ends of both sides of the front of the collection frame 2. An electric push rod 52 is fixedly installed inside the mounting sleeve 51. A bending connecting rod 53 is fixedly installed at the output end of the electric push rod 52. A clamping assembly 54 is fixedly installed at the outer end of the bending connecting rod 53. The bending connecting rod 53 clamps the alloy part 4 to be polished through the clamping assembly 54. The clamping assembly 54 includes a concave seat 541, which is fixedly installed at the outer end of the bending connecting rod 53. An adjusting screw 542 is threadedly connected to the top of the concave seat 541. The bottom of the adjusting screw 542 passes through the upper end of the concave seat 541 and is rotatably connected to a clamping plate 543. Support shafts 544 are fixedly connected to both sides of the top of the clamping plate 543. The top of the support shafts 544 passes through the concave seat 541. The alloy part 4 to be polished is clamped inside the concave seat 541 by the clamping plate 543. By setting the clamping mechanism 5, the mounting sleeve 51 can be clamped inside the concave seat 541 during use. 1. The built-in electric push rod 52 of the mounting sleeve 51 is fixed to the upper ends of both sides of the front of the collection frame 2 by bolts. When the electric push rod 52 is started, its output end pushes the bending connecting rod 53 connected to it to move. The outer end of the bending connecting rod 53 is equipped with a clamping assembly 54, in which the concave seat 541 is fixed to the outer end of the bending connecting rod 53. When it is necessary to clamp the alloy part 4 to be polished, the alloy part is placed in the concave seat 541. The adjusting screw 542 connected to the top of the concave seat 541 is rotated. The bottom of the adjusting screw 542 drives the clamping plate 543 to move downward. The support shafts 544 on both sides of the top of the clamping plate 543 play a guiding role in the concave seat 541 to ensure that the clamping plate 543 descends smoothly until the clamping plate 543 tightly clamps the alloy part 4 to be polished inside the concave seat 541. Then, the electric push rod 52 continues to work, pushing the clamping assembly 54 and the clamped alloy part to move through the bending connecting rod 53, so that it enters the inner side of the polishing mechanism 3 for polishing.

[0029] Operating principle and advantages: This device, by setting up polishing mechanism 3, can effectively enhance its adaptability and work efficiency in the polishing process of magnesium alloy die castings. In actual operation, the first motor 335 is started. The power generated by the first motor 335 drives the lead screw 332 to rotate inside the side rail 331. Since the threads at both ends of the lead screw 332 turn in opposite directions, during the rotation of the lead screw 332, it can drive the slider 333 to reciprocate linearly within the side rail 331. The reciprocating sliding of the slider 333 further drives the movable block 321 to slide inside the frame 31. By flexibly adjusting the sliding position of the movable block 321 within the frame 31, the two polishing groups can be precisely driven. The component 32 moves back and forth. By adjusting the distance between the two polishing components 32, the device can flexibly adapt to magnesium alloy die castings of different thicknesses to be polished. When polishing, it is only necessary to drive the polishing rollers 323 of the two polishing components 32 to move inward so that they fit tightly against the outer surface of the magnesium alloy die casting to be polished. Then, the second motor 322 is started. The second motor 322 drives the polishing rollers 323 to rotate at high speed. The polishing rollers 323 are then used to achieve efficient polishing of the outer surface of the magnesium alloy die casting to be polished. This design greatly improves the polishing adaptability of the device in actual use and significantly enhances the application range and versatility of the equipment.

[0030] This device, with its clamping mechanism 5, provides strong support for the stable fixation and automated processing of magnesium alloy die castings to be polished during use. During operation, the magnesium alloy die casting to be polished is placed inside the concave seat 541. Then, by rotating the adjusting screw 542, it is moved downwards. The downward movement of the adjusting screw 542 causes the clamping plate 543 to move downwards synchronously. During the downward movement of the clamping plate 543, it tightly clamps the outer surface of the magnesium alloy die casting to be polished. During the downward adjustment of the clamping plate 543, the support shaft 544 provides support and guidance, ensuring that the clamping plate 543 can move smoothly up and down, thereby achieving the stability of the magnesium alloy die casting to be polished. After clamping the magnesium alloy die-casting to be polished, the electric push rod 52 is activated. The thrust generated by the electric push rod 52 assists in moving the bending connecting rod 53. The movement of the bending connecting rod 53 further displaces the magnesium alloy die-casting to be polished, which is held by the clamping assembly 54 at its end. This causes the magnesium alloy die-casting to be polished to move laterally between the polishing rollers 323. By continuously controlling the operation of the electric push rod 52, the reciprocating lateral movement of the magnesium alloy die-casting to be polished between the polishing rollers 323 can be realized, thereby achieving automated and efficient polishing of its top and bottom. This greatly improves the convenience and efficiency of polishing during the overall use of the device.
