Description

Technical Field

[0001] This utility model relates to the field of alloy casting processing technology, and in particular to a polishing mechanism for the inner wall of aluminum alloy castings. Background Technology

[0002] Aluminum alloy castings refer to parts with specific shapes made from aluminum alloys (aluminum as the base material, with the addition of alloying elements such as copper, magnesium, silicon, and zinc to optimize performance) through a "casting process". After casting, the inner wall of cylindrical aluminum alloy castings may have defects such as rough protrusions, residual casting sand particles, micro-pores, and machining marks, which directly affect its performance. Therefore, the inner wall is polished.

[0003] However, the polishing wheel used for polishing has a fixed diameter. If you need to polish cylindrical castings of different diameters, you need to change to a polishing wheel of a different diameter, which will cause the polishing equipment to be shut down for a long time, thus reducing the polishing efficiency. Utility Model Content

[0004] This invention provides a polishing mechanism for the inner wall of aluminum alloy castings. By raising and lowering the sliding component, the distance between the four protrusions and the polishing belt can be changed, thereby changing the circumferential diameter formed by the four polishing belts. This allows for polishing of the inner wall of aluminum alloy castings with different diameters. Only a short pause is needed to adjust the diameter of the adjusting structure, eliminating the need for cumbersome replacement of polishing wheels. This improves the polishing efficiency of aluminum alloy castings and enhances production efficiency.

Detailed Implementation

[0023] 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, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0025] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0026] like Figures 1 to 4 As shown, this application provides an aluminum alloy casting inner wall polishing mechanism, including: a diameter adjustment structure 4, which is disposed on the outer side of one end of the main rotating shaft 2. The diameter adjustment structure 4 is provided in four sets. The diameter adjustment structure 4 is adapted to change the polishing diameter under the adjustment of the adjustment component 3, and is used to polish aluminum alloy castings 5 ​​of different diameters.

[0027] The diameter adjustment structure 4 includes a sliding member 401. A drive arm 402 is rotatably provided on one side of the sliding member 401, and an end bracket 403 is rotatably provided at the other end of the drive arm 402. A receiving plate 404 and a protrusion 405 are fixedly provided on the other side of the end bracket 403. A lug 407 is fixedly provided on one side of the receiving plate 404 by bolts. A polishing belt 406 is fixedly provided between the lugs 407. A guide component is provided on one side of the end bracket 403. The guide component is located at the bottom end of the sliding member 401 and is used to stabilize the lateral position of the protrusion 405 and the polishing belt 406.

[0028] After adopting the above technical solution, when increasing the polishing diameter, it is necessary to lower the four sliding components 401. The lowering of the sliding components 401 causes the included angle between the drive arm 402 and the main rotating shaft 2 to gradually increase. At the same time, the end bracket 403, the receiving plate 404 and the protrusion 405 will be driven to move laterally, so that the protrusion 405 gradually moves away from the main rotating shaft 2, thereby achieving the effect of increasing the polishing diameter. If the sliding components 401 rise, the polishing diameter will decrease. The setting of the lug 407 makes the polishing belt 406 easy to replace. When the polishing belt 406 is no longer usable, a new polishing belt 406 can be replaced, thus eliminating the need for cumbersome replacement of polishing wheels and improving the polishing efficiency of aluminum alloy castings, thereby improving production and processing efficiency.

[0029] It should be noted that four grooves 201 are provided on the outer side of the main rotating shaft 2, the sliding component 401 is slidably disposed on the inner side of the groove 201, the protrusion 405 is semi-circular and made of rubber material, and the polishing belt 406 is attached to the outer side of the protrusion 405.

[0030] In an optional embodiment, the four grooves 201 are provided for sliding of the sliding member 401 during adjustment, and the protrusion 405 is set as a semi-circle and made of rubber, so that after adjusting the polishing diameter of the diameter adjustment structure 4, the polishing strip 406 can be tightly attached to the inner wall of the aluminum alloy casting 5, and the 450 is deformed by compression, increasing the contact area between the polishing strip 406 and the inner wall of the aluminum alloy casting 5, thereby achieving a better polishing effect.

[0031] Specifically, the guide assembly includes a stabilizing telescopic rod 408, which includes a fixed rod and a movable rod. The movable rod is slidably disposed inside the fixed rod. A rod end seat 410 is fixedly disposed at the end of the fixed rod that is away from the movable rod. The rod end seat 410 is fixedly connected to the end connector 403. A fixing block 411 is fixedly disposed on one side of the other rod end seat 410. The fixing block 411 is fixedly disposed at the bottom inner side of the slide groove 201.

[0032] The movable rod is provided with a first spring 409 on its outer side. The first spring 409 is fixedly disposed between the stable telescopic rod 408 and the rod end seat 410. The top of the fixed block 411 is fixedly disposed with a second spring 412. The second spring 412 is fixedly disposed at the bottom of the sliding member 401.

[0033] In an optional embodiment, during adjustment, the movable rod slides inside the fixed rod, allowing the stabilizing telescopic rod 408 to change with the adjusted diameter and preventing the end bracket 403, the receiving plate 404, and the protrusion 405 from leaving their original lateral positions, thus providing a guiding and fixing effect. If the diameter adjustment structure 4 has been adjusted to the maximum polishing diameter, the first spring 409 remains in a compressed state, thereby providing a top force to the end bracket 403, the receiving plate 404, and the protrusion 405 at all times, ensuring that the lateral position of the adjusted protrusion 405 does not change arbitrarily. The second spring 412 is also in a compressed state, providing an upward force to the sliding member 401. The upward force is transmitted to the screw barrel 302 through the receiving column 306, making the screw barrel 302 and the screw ring 301 more secure and preventing easy loosening, thus improving safety during polishing.

[0034] For example, the adjusting component 3 includes a screw ring 301, with a screw cylinder 302 threadedly connected to the inner side of the screw ring 301. The screw cylinder 302 is slidably disposed on the outer side of the main rotating shaft 2. The screw cylinder 302 is fixedly connected to the sliding member 401 through a plurality of bearing posts 306. A fixed shaft 303 is rotatably disposed on the top of the screw ring 301. The other end of the fixed shaft 303 is fixedly connected to a fixed ring 305 through a plurality of connecting rods 304. The fixed ring 305 is fixedly disposed on the outer side of the main rotating shaft 2.

[0035] In an optional embodiment, when adjusting the polishing diameter of the adjusting structure 4, the screw ring 301 is rotated so that the screw barrel 302 can move up and down on the outside of the main rotating shaft 2. The screw barrel 302 can drive the sliding component 401 to slide up and down on the inside of the slide groove 201 through the support column 306, thereby achieving the effect of adjusting the polishing diameter of the adjusting structure 4. When not adjusting, the screw ring 301 and the screw barrel 302 will not rotate arbitrarily. Since the fixing ring 305 is fixed on the outside of the main rotating shaft 2, the adjusting component 3 will rotate along with the main rotating shaft 2 when it rotates.

[0036] For example, a servo motor 102 is provided at the other end of the main rotating shaft 2. A support frame 101 is fixedly provided at the bottom end of the servo motor 102. A hydraulic rod 1 is fixedly provided on one side of the bottom end of the support frame 101. A hydraulic cylinder is externally connected to the hydraulic rod 1. The main rotating shaft 2 is fixedly connected to the drive end of the servo motor 102. The drive end of the servo motor 102 passes through and rotates on the top end of the support frame 101.

[0037] In an optional embodiment, the working height of the diameter adjustment structure 4 can be adjusted by extending or shortening the hydraulic rod 1, thereby enabling comprehensive polishing of the inner wall of the aluminum alloy casting 5. The rotation of the main shaft 2 is driven by the servo motor 102, which facilitates the polishing process.
