Description

Technical Field

[0001] This utility model belongs to the field of grinding technology for cast aluminum parts, and in particular relates to a tooling for grinding cast aluminum automotive parts. Background Technology

[0002] Automobiles are an important means of transportation for people's daily travel, and many of their parts are made of cast aluminum. Cast aluminum is a process in which molten aluminum is poured into a mold and cooled to form an aluminum part of the required shape. The resulting casting is called an aluminum casting. During the processing of cast aluminum parts, some parts may develop burrs or be too rough, thus requiring polishing.

[0003] A search revealed a patent with application number 202021029018.1, which discloses an efficient grinding device for the edges of cast aluminum parts. This patent, by setting up a first grinding device and a second grinding device to work together, can quickly and efficiently grind the edges of cylindrical parts, improving grinding efficiency and quality. This utility model has a simple structure and is easy to operate. However, it uses a clamping method for the parts, which may cause the clamped parts to be ground incompletely. Moreover, it requires stopping the machine to adjust the position of the parts, which is troublesome, increases the processing time of the parts, and results in low processing efficiency.

[0014] See appendix Figure 1-2 As shown, a tooling for grinding cast aluminum automotive parts includes a base 1 and a clamping mechanism 4. Two symmetrical support rods 2 are fixed to the upper side of the base 1, and an annular block 3 is fixed to the upper end of each support rod 2. The clamping mechanism 4 includes a first hydraulic cylinder 41, a movable frame 42, a reduction motor 43, and rollers 44. At least three mounting holes are provided on the side of the annular block 3, equidistantly arranged around the central axis of the annular block 3. A first hydraulic cylinder 41 is installed in each mounting hole, and a movable frame 42 is installed at the telescopic end of each first hydraulic cylinder 41. The movable frame 42 has a U-shaped structure, and a reduction motor 43 is installed on the upper side of each movable frame 42. The output shaft of each reduction motor 43 extends into the inner side of the movable frame 42, and the output shaft of the reduction motor 43... Each output shaft is fitted with a roller 44. A support tray 6 is fixed to the upper side of the base 1 via a driven shaft 5. The support tray 6 is located directly below the central axis of the annular block 3. A fixing frame 7 is fixed to the upper side of the annular block 3. The fixing frame 7 has a "U" shaped structure. A limiting mechanism 8 is provided on the bottom side of the horizontal end of the fixing frame 7. By setting a clamping mechanism 4, the automotive cast aluminum parts can be rotated. The dynamic clamping method avoids the situation where the clamping part is not ground properly. It also avoids the trouble of frequently changing the grinding position of the cast aluminum parts manually. No machine stoppage is required, which greatly saves the part processing time and improves work efficiency. By setting a driven shaft 5 and a support tray 6 on the base 1, the cast aluminum parts can be placed to prevent them from shifting during processing.

[0015] The limiting mechanism 8 includes a second hydraulic cylinder 81, a bearing 82, and a pressure plate 83. The second hydraulic cylinder 81 is installed on the bottom side of the horizontal end of the fixed frame 7. The extension end of the second hydraulic cylinder 81 is rotatably connected to the pressure plate 83 through the bearing 82. The pressure plate 83 is located directly above the central axis of the annular block 3, and the pressure plate 83 is coaxially arranged with the support tray 6. By setting the limiting mechanism 8, the upper end of the cast aluminum part can be fixed, and in conjunction with the support tray 6, the stability during processing is ensured.

[0016] Working principle: The cast aluminum automotive part to be ground is placed inside the annular block 3, with its bottom end contacting the upper side of the support tray 6. Then, the first hydraulic cylinder 41 extends, thereby driving the moving frame 42 to move closer together. The cast aluminum automotive part is clamped by the rollers 44 inside the moving frame 42. The reduction motor 43 drives the rollers 44 to rotate, thereby driving the cast aluminum automotive part and the support tray 6 to rotate simultaneously. In conjunction with the external grinding mechanism, it is ground. The dynamic clamping method avoids the situation of incomplete grinding of the clamping part and avoids the trouble of frequently changing the grinding position of the cast aluminum part manually. No machine downtime is required, which greatly saves the processing time of the parts and improves the work efficiency. After the cast aluminum automotive part is clamped by the clamping mechanism 4, the second hydraulic cylinder 81 drives the pressure plate 83 to move downward through the bearing 82 to fix the upper end of the cast aluminum automotive part. In conjunction with the support tray 6, it ensures the stability of the part during processing.
