Technical Field

[0001] This utility model belongs to the field of alloy trimming technology, specifically, it relates to an aluminum alloy trimming device. Background Technology

[0002] Compared to traditional steel, aluminum alloys have a lower density, resulting in lighter weight per unit volume. They also possess high strength and excellent electrical and thermal conductivity, giving them superior performance in harsh environments such as high temperature and high pressure. Furthermore, the oxidation of aluminum creates a dense and robust Al2O3 protective film, effectively protecting the substrate from corrosion. Aluminum is also easy to process, and with the addition of certain alloying elements, cast aluminum alloys with good casting properties or wrought aluminum alloys with good processing plasticity can be obtained. Currently, many mechanical components in the aerospace field use aluminum alloys as the main constituent material.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0022] like Figures 1 to 4 As shown, an aluminum alloy finishing device includes a base 1, a groove 2 is provided on the upper surface of the base 1, and a grinding mechanism is provided at the upper end of the base 1.

[0023] The top of the support column 9 is provided with a threaded hole, and a fixing bolt 12 is threaded into the threaded hole.

The lower end shaft of the grinding rod 10 and the anti-slip tooth 20 correspond to the mounting hole opened inside the bushing 19 and are sleeved and installed there.

[0024] In this design, the present invention employs a longitudinal grinding column and a rotating table, which can be used to remove burrs from aluminum alloy parts of various shapes, such as circles and polygons, greatly increasing flexibility and adaptability. At the same time, the quick-release design makes it easy to quickly replace the grinding rod.

[0025] like Figures 1 to 4 As shown, in a specific embodiment, a sliding frame 5 is fixedly connected to the lower end of the support column 9, and sliders 21 are fixedly connected to the lower ends of both ends of the sliding frame 5. The sliders 21 correspond to the sliding groove 2 and are slidably sleeved with it. A positioning frame 3 is slidably engaged inside the sliding groove 2. The lower ends of the positioning frame 3 correspond to the sliding groove 2, and a sliding rod 22 is installed inside the sliding groove 2. The two ends of the sliding rod 22 are fixedly connected to the base 1. The sliding rod 22 passes through the sliders 21 and the two ends of the positioning frame 3 and is slidably sleeved with them. A threaded hole is opened in the middle of the positioning frame 3. A positioning bolt 16 is threaded into this threaded hole, and a spring 4 is fixedly connected between the two ends of the positioning frame 3 and the slider 21. The spring 4 is movably sleeved on the rod body of the sliding rod 22.

[0026] In this setup, the support column 9 is moved by sliding the positioning bracket 3 until the sanding rod 10 contacts the edge of the aluminum alloy part and generates appropriate pressure. Then, the positioning bolt 16 is rotated to fix the positioning bracket 3 on the base 1.

[0027] like Figures 1 to 4 As shown, in a specific embodiment, a lower bearing seat 6 is fixedly connected to the middle position of the base 1, a lower turntable 7 is movably installed on the upper end of the lower bearing seat 6, a connecting plate 27 is fixedly connected to one side of the base 1, a sleeve 24 is fixedly connected to one outer end of the connecting plate 27, a telescopic plate 25 is movably sleeved inside the sleeve 24, a support plate 15 is fixedly connected to the upper end of the telescopic plate 25, and a hydraulic cylinder 26 is fixedly connected to the upper surface of the connecting plate 27.

[0028] In this setup, when using this equipment, the center part of the aluminum alloy part to be repaired is first placed on the surface of the lower turntable 7, and then the hydraulic cylinder 26 is activated to retract, and the aluminum alloy part is clamped by the upper turntable 13.

[0029] like Figures 1 to 4 As shown, in a specific embodiment, the end of the telescopic rod at the upper end of the hydraulic cylinder 26 is fixedly connected to the lower end of the support plate 15. An upper bearing seat 23 is fixedly connected to the lower surface of one end of the support plate 15. An upper turntable 13 is movably installed at the lower end of the upper bearing seat 23.

The transmission shaft at the lower end of the first motor 14 passes through the support plate 15 and the upper bearing seat 23 and is fixedly connected to the center position of the upper turntable 13.

[0030] In this setup, the first motor 14 and the second motor 8 are started. The first motor 14 drives the aluminum alloy part to rotate through the upper turntable 13, and the second motor 8 drives the polishing rod 10 to rotate at high speed, while polishing the edge of the aluminum alloy part. If the aluminum alloy part is round, the position of the polishing rod 10 remains unchanged. When the aluminum alloy part is elliptical or polygonal, it will squeeze the polishing rod 10 to move to both sides and squeeze the spring 4 when it rotates, so as to adapt to the changing shape and keep the polishing rod 10 in close contact with the edge of the aluminum alloy part.

[0031] The implementation principle of the aluminum alloy trimming device in this embodiment is as follows:

[0032] This utility model, by adopting a longitudinal grinding column and a rotating table design, can remove burrs from aluminum alloy parts of various shapes such as circles and polygons, greatly increasing flexibility and adaptability. At the same time, the quick-release design makes it easy to quickly replace the grinding rod 10.

[0033] When using this equipment, first place the center of the aluminum alloy part to be repaired on the surface of the lower turntable 7, then start the hydraulic cylinder 26 to retract, clamp the aluminum alloy part through the upper turntable 13, and then move the support column 9 through the sliding positioning frame 3 until the grinding rod 10 contacts the edge of the aluminum alloy part and generates appropriate pressure. Then rotate the positioning bolt 16 to fix the positioning frame 3 on the base 1, and then start the first motor 14 and the second motor 8. The first motor 14 drives the aluminum alloy part to rotate through the upper turntable 13, and the second motor 8 drives the grinding rod 10 to rotate at high speed, while grinding the edge of the aluminum alloy part. At this time, if the aluminum alloy part is round, the position of the grinding rod 10 remains unchanged. When the aluminum alloy part is elliptical or polygonal, it will squeeze the grinding rod 10 to move to both sides when it rotates, and squeeze the spring 4, so as to adapt to the changing shape and keep the grinding rod 10 in close contact with the edge of the aluminum alloy part.
