Description

TECHNICAL FIELD

[0001] The utility model mainly relates to die casting processing technical field, concretely relates to a surface polishing device for die casting. BACKGROUND

[0002] Die casting is an important product in metal forming process, and burrs, oxide layers or rough textures often exist on its surface, which need to be polished to improve the smoothness, aesthetics and functionality. Currently, the industry generally uses motor-driven polishing devices to grind the workpiece surface through high-speed rotation or vibration of the polishing head. The traditional polishing device is usually composed of a power unit, a connecting shaft and a detachable polishing head. During operation, different roughness polishing heads need to be replaced in sequence according to the polishing process requirements. For example, a coarse-grained polishing head is used to remove obvious defects in the initial stage, followed by a medium-grained polishing head for transitional polishing, and finally a fine-grained polishing head for fine polishing.

[0003] However, the existing technology has significant shortcomings: because different polishing stages require frequent replacement of polishing heads, operators must repeatedly stop, disassemble the old polishing head and install the new one. This process not only consumes time and effort, resulting in reduced processing efficiency, but also easily causes the polishing head to become loose or eccentric due to operational errors, affecting the stability of the polishing quality.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Example

[0031] See attached document Figures 1-6 A surface polishing device for die castings includes a base 1 and a Y-axis platform 2 and an XZ-axis platform 3 disposed thereon. A single-axis motor 5 is mounted on the Z-axis of the XZ-axis platform 3. The output shaft of the single-axis motor 5 is fixedly connected to a horizontally extending slide rail 6. A guide slide member 7 is slidably fitted inside the slide rail 6.

[0032] The bottom surface of the guide slide 7 has three telescopic mechanisms 8 equidistantly distributed along the extension direction of the slide rail 6, and each telescopic mechanism 8 has a polishing head 9 with a different polishing roughness installed at its bottom end. The working end of each polishing head 9 faces the carrier plate 4 set on the top of the Y-axis platform 2.

[0033] In this embodiment, after the die-cast part to be polished is placed on the carrier plate 4, the die-cast part can be polished by moving the Y-axis platform 2 and the XZ-axis platforms 3, in conjunction with the polishing head 9. After the guide slide 7 slides in the slide rail 6, the polishing head 9 with different polishing roughness can be moved to the center of the slide rail 6. In conjunction with the telescopic mechanism 8 for lifting and lowering, the die-cast part can be polished from coarse to fine without changing the polishing head 9, which reduces labor intensity and improves work efficiency.

[0034] The guide slide 7 is equipped with a dual-axis motor 10. The two output ends of the dual-axis motor 10 are connected to lead screws 11 through connecting shafts. Each lead screw 11 is threaded into the threaded hole at the end of the locking block 12. The locking block 12 is slidably connected to the movable groove 701 opened inside the guide slide 7. The movable groove 701 is adapted to the three sets of locking grooves 601 opened inside the slide rail 6.

[0035] The three sets of locking grooves 601 are distributed at equal intervals along the length of the slide rail 6, and the center distance between two adjacent locking grooves 601 is equal to the center distance between two adjacent polishing heads 9.

[0036] In this embodiment, after the dual-axis motor 10 is started to rotate in both directions, the lead screw 11 can be driven to rotate synchronously so that the locking block 12 slides in the movable groove 701. When the movable groove 701 is aligned with the locking groove 601, the locking block 12 can enter the locking groove 601 to lock the guide slide 7. The center distance between two adjacent locking grooves 601 is equal to the center distance between two adjacent polishing heads 9. Therefore, when the two locking blocks 12 enter the three sets of locking grooves 601, they can lock different polishing heads 9 at the center of the slide rail 6 respectively.

[0037] The guide slide 7 is provided with elastic components 13 at both ends. The elastic components 13 include fixing blocks 131 fixed to the ends of the guide slide 7. The fixing blocks 131 have first sliding grooves 132 on both sides. The first sliding grooves 132 are adapted to three sets of slots 602 on the inner side of the slide rail 6. A locking block 133 is slidably assembled in the first sliding groove 132. A guide slide post 134 is integrally formed at the end of the locking block 133. A spring 136 is sleeved on the guide slide post 134 and slidably installed in a second sliding groove 135 that is connected to the end of the first sliding groove 132. The three sets of slots 602 are evenly distributed along the length of the slide rail 6, and the center distance between two adjacent slots 602 is equal to the center distance between two adjacent polishing heads 9.

[0038] In this embodiment, when the guide slide 7 slides within the slide rail 6, when one of the polishing heads 9 is located at the center of the slide rail 6, the two first slide grooves 132 will align with one set of slots 602. At this time, under the elastic force of the spring 136, the two locking blocks 133 can engage with this set of slots 602 to initially lock the guide slide 7. Then, the dual-axis motor 10 can be started to drive the two locking blocks 12 into the locking grooves 601 of the alignment group to further lock the guide slide 7.

[0039] A limiting groove 137 is provided on one side of the first sliding groove 132. The limiting groove 137 extends to the outside of the fixing block 131 and is provided with a limiting block 138 inside. The limiting block 138 is detachably connected to the locking block 133.

[0040] In this embodiment, after pulling the limiting block 138, the locking block 133 can be driven away from the slot 602, thereby releasing the locking of the guide slide 7 in the slide rail 6. After removing the guide slide 7 from the slide rail 6, the limiting block 138 can be removed, and the locking block 133 and the guide slide 134 can be taken out, so that the spring 136 can be replaced.

[0041] The telescopic mechanism 8 includes a fixed rod 81 and an extension rod 82. One end of the fixed rod 81 is fixed to the bottom of the guide slide 7 and has two first threaded holes 84 spaced longitudinally. The bottom of the extension rod 82 is detachably connected to the polishing head 9. A guide slide sleeve 83 integrally formed on one side is slidably connected to the fixed rod 81. The guide slide sleeve 83 has a second threaded hole 85 that matches the first threaded hole 84. A hand screw 86 is installed in the second threaded hole 85.

[0042] In this embodiment, the extension rod 82 can slide on the fixed rod 81 through the guide sleeve 83. When the second threaded hole 85 is aligned with the first threaded hole 84, tightening the hand screw 86 to make it enter the first threaded hole 84 can lock the extension rod 82. Since there are two first threaded holes 84 spaced longitudinally, the extension rod 82 can be locked at different heights to achieve the raising and lowering of the polishing head 9.

[0043] An electromagnet is installed inside the carrier plate 4;

[0044] The top of the carrier plate 4 is provided with a protective cover 14, and a number of evenly distributed insertion rods 141 are installed at the bottom of the protective cover 14. The insertion rods 141 are inserted into the insertion holes 401 opened on the top of the carrier plate 4.

[0045] In this embodiment, an electromagnet is provided inside the carrier plate 4. When energized, it can magnetically attract the die-casting part for limiting its movement during polishing. Most of the waste generated during polishing can be blocked by the protective cover 14. The bottom of the protective cover 14 is inserted into the insertion hole 401 opened on the top of the carrier plate 4 via a plug rod 141 for disassembling the protective cover 14 to facilitate the disposal of waste.

However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
