Description

Technical Field

[0001] This utility model relates to a deburring device, and more particularly to a deburring device for the inner ring of a die-cast part. Background Technology

[0002] Die casting refers to parts produced by pressure casting. It is a process in which molten metal is poured into the feed port of a die casting machine equipped with a casting mold, and the parts are die-cast. After die casting, the inner ring of the part will have burrs, which require a special deburring device to polish and remove the burrs. Existing deburring devices produce metal debris during the polishing process, which is difficult to clean and recycle. Therefore, there is an urgent need for a new type of deburring device for the inner ring of die castings to solve the above technical problems. Utility Model Content

[0022] Example:

[0023] Reference Figure 1-6 As shown, a preferred embodiment of this utility model provides a deburring device for the inner ring of a die-cast part, including a base 1, which is L-shaped. Several support legs 2 are fixedly installed at the bottom of the base 1. A fixing plate 3 is fixedly installed on the side wall of the base 1. A cylinder 4 is fixedly installed on the fixing plate 3. One end of the piston rod 5 of the cylinder 4 passes through the fixing plate 3 and is provided with a mounting block 6, symmetrical connecting plates 8, and symmetrical grinding parts 10. A mold 18 is provided on the base 1. A working groove 19 is opened on the mold 18. Symmetrical inner grooves 20 are opened in the working groove 19. An inner cavity 22 is opened in the mold 18. The outer grooves of the symmetrical inner grooves 20 are... A symmetrical collection cylinder 23 is fixedly installed at the bottom. A connecting pipe 25 is fixedly connected to the bottom of the symmetrical collection cylinder 23. Several fans 27 are fixedly installed inside the connecting pipe 25. One end of the connecting pipe 25 passes through the mold 18 and is fixedly connected to a collection box 26. The collection box 26 is placed on one side of the mold 18. After the cylinder 4 is started, its piston rod 5 will drive the symmetrical grinding parts 10 to grind and deburr the inner ring of the die-casting part in the working groove 19. During grinding, metal chips will be generated and fall into the inner groove 20. After the fans 27 are started, they can form a suction airflow to draw the chips from the through groove 21 into the collection box 26.

[0024] Secondly, the bottom of the symmetrical inner groove 20 is provided with a through groove 21 that communicates with the symmetrical collection cylinder 23. A filter ring 24 is fixedly installed inside the inner wall of the symmetrical collection cylinder 23. The filter ring 24 can intercept and filter dust and impurities, thereby improving the purity and quality of the collected metal scraps.

[0025] Secondly, the mounting block 6 is fixedly connected to one end of the piston rod 5. The mounting block 6 has slots 7 on both sides. The bottom of the symmetrical connecting plates 8 is provided with grinding parts 10. The grinding part 10 on one side is fixedly installed on the bottom of the connecting plate 8 on one side. The first motor 11 is fixedly installed on the connecting plate 8 on the other side. One end of the output shaft of the first motor 11 passes through the connecting plate 8 on the other side and is fixedly connected to the grinding part 10 on the other side. The side walls of the symmetrical connecting plates 8 are fixedly installed with locking blocks 9. The locking blocks 9 are locked in the slots 7. The symmetrical grinding parts 10 are located above the symmetrical inner grooves 20 and are adapted to them. After the first motor 11 is started, it can drive the grinding part 10 on the other side to rotate, so as to facilitate friction grinding of the inner groove 20 on the side below that is adapted to it. At the same time, the locking blocks 9 and the slots 7 facilitate the disassembly and replacement of the connecting plates 8 to adapt to different die-cast parts.

[0026] Finally, a sliding groove 12 is provided through the base 1. Symmetrical fixed seats 13 are fixedly installed on the bottom of the base 1 on both sides of the sliding groove 12. A second motor 14 is fixedly installed on the side wall of one fixed seat 13. One end of the output shaft of the second motor 14 passes through the fixed seat 13 and is fixedly connected to a bidirectional screw 15. One end of the bidirectional screw 15 is rotatably installed on the other fixed seat 13. Symmetrical connecting blocks 16 are threaded on the bidirectional screw 15. Limiting plates 17 are fixedly installed on the symmetrical connecting blocks 16. The symmetrical limiting plates 17 are used to clamp and fix the mold 18. After the second motor 14 is started, it can drive the bidirectional screw 15 to rotate and control the connecting blocks 16 on both sides and the limiting plates 17 fixedly connected to the connecting blocks 16 to move towards each other and clamp and fix the mold 18 in the middle, so as to fix and adapt molds 18 of different sizes and styles.

[0027] When operation is required, the mold 18 containing the die-casting part is placed between the two limiting plates 17. The second motor 14 is started to control the two limiting plates 17 to move towards each other until the mold 18 is clamped and fixed. Then, the collection box 26 is placed on one side of the mold 18. After that, according to the style and shape of the working groove 19 and inner groove 20 of the mold 18, the appropriate connecting plate 8 is selected and snapped onto both sides of the mounting block 6. After installation, the cylinder 4 and the first motor 11 are started to drive the piston rod 5 to move the grinding parts 10 on both sides downward and grind and deburr the inner ring of the die-casting part in the mold 18. During the grinding process, several fans 27 are started to generate suction airflow, which draws the metal chips generated by grinding into the connecting pipe 25 through the through groove 21 and finally into the collection box 26. At the same time, the filter ring 24 can intercept and filter the dust and impurities that fall into the inner groove 20 during the grinding process, thereby increasing the purity and quality of the collected metal chips.
