Description

Technical Field

[0001] The utility model relates to the technical field of die casting edge processing, in particular to an edge grinding device for die casting processing. Background Art

[0002] Die-casting edge grinding is a crucial process step. It involves the use of professional grinding tools and techniques to finely process the edges of die-castings to remove burrs, sharp edges and uneven surfaces, ensuring that the die-castings achieve the required dimensional accuracy, surface finish and appearance quality. This process is of great significance for improving the overall quality of die-castings, enhancing their performance and extending their service life. It also provides a good foundation for subsequent assembly, painting and other processes.

[0003] Some high-precision die-casting parts have complex structures and often require manual grinding of their edges. Different edge positions require different sized grinding heads to ensure grinding accuracy. When replacing the grinding head of the existing grinder, the original grinding head needs to be removed and put aside before installing the appropriate grinding head. The replacement steps are cumbersome, which reduces the grinding efficiency. In addition, the grinding head is small in size and is easy to lose after disassembly, resulting in unnecessary waste and increased production costs. Utility Model Content

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods. Example 1:

[0020] like Figure 1-4 The edge grinding device for die casting processing shown in the figure includes a grinder body 1, the front end of the grinder body 1 is rotatably connected to a connecting shaft 6, the connecting shaft 6 is connected to the driving device inside the grinder body 1 to drive the grinding device, the front end of the connecting shaft 6 is fixedly connected to a fixed disk 5, and when the connecting shaft 6 rotates, the fixed disk 5 is driven to rotate, the outer surface of the connecting shaft 6 is threadedly connected to a movable block 18, the outer surface of the movable block 18 is fixedly connected to a bearing 17, and the outer surface of the bearing 17 is movably connected to a connecting rod 16, through By setting a bearing 17, the connecting rod 16 will not rotate when the movable block 18 rotates. The outer surface of the fixed disk 5 is movably connected to the first grinding head 3 for grinding larger edges. The inner wall of the first grinding head 3 is provided with multiple groups of pin holes 10. The inner wall of the pin hole 10 is slidably connected with a pin block 15. When the pin block 15 is inserted into the pin hole 10, the fixed disk 5 and the first grinding head 3 can be fixed together, thereby achieving the purpose of driving the first grinding head 3 to grind. The front end of the grinder body 1 is provided with two groups of symmetrical shelf grooves 2;

[0021] The tail end of the connecting rod 16 is movably connected to the top of the pin block 15, and the pin block 15 is slidably connected to the inner wall of the fixed plate 5. When the inclination angle of the connecting rod 16 changes, the pin block 15 will be driven to slide; the inner walls of the two groups of shelf grooves 2 are slidably connected with a connecting rod 12, and the front end of the connecting rod 12 is fixedly connected to the fixed block 4. The tail end of the connecting rod 12 is fixedly installed with a spring 13, and a telescopic rod is provided inside the spring 13. The bottom walls of the two groups of shelf grooves 2 are fixedly installed with a mounting block 14, and the mounting block 14 is fixedly connected to the tail end of the spring 13. When the fixed block 4 is squeezed, it will retract into the shelf groove 2. When the pressure disappears, under the action of the spring 13, the fixed block 4 rebounds and resets; the inner wall of the first grinding head 3 is provided with two groups of limiting grooves 8, and the limiting grooves 8 are set to be inclined , so that when the first grinding head 3 moves upward, the limiting groove 8 can squeeze the fixing block 4 into the shelf groove 2, and the inner wall of the first grinding head 3 is provided with two groups of limiting holes 9, and the limiting holes 9 are located below the limiting groove 8.

After the fixing block 4 slides to the through groove 7, the first grinding head 3 is rotated and the fixing block 4 is aligned with the strip groove 11, which can release the fixation of the first grinding head 3 and enable the first grinding head 3 to move downward; the tail end of the connecting shaft 6 is fixedly installed with a second grinding head 19 for grinding smaller edges.

[0022] It should be noted that the present invention is an edge grinding device for die-casting processing. When in use, when grinding a smaller edge, the driving power inside the grinder body 1 is turned off to fix the connecting shaft 6. Then, the movable block 18 is rotated. Under the action of the thread engagement, the movable block 18 drives the front end of the bearing 17 and the connecting rod 16 to move upward. The pin block 15 is disengaged from the pin hole 10 under the action of the connecting rod 16, thereby releasing the fixation of the first grinding head 3. The first grinding head 3 is lifted upward, so that the fixed block 4 passes through the limiting groove 8 and rebounds into the limiting hole 9 under the action of the spring 13. When the first grinding head 3 is used, the first grinding head 3 is lifted upwards so that the fixing block 4 is located in the through groove 7. Then, the first grinding head 3 is rotated so that the fixing block 4 is aligned with the strip groove 11, and the first grinding head 3 can be moved downwards until the top of the first grinding head 3 is aligned with the top of the fixed plate 5. The movable block 18 is rotated in the opposite direction to fix the first grinding head 3 using the pin block 15. The operation steps are simple and the replacement speed is fast.
