DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Reference Figure 1-3 , a surface deburring device for die-casting hardware, comprising:

[0025] The base 1 has a top plate 12 fixedly connected to the top of the base 1 via four support rods 11. A grinding device 13 is provided below the top plate 12. A rotating disk 15 is rotatably connected to the top of the base 1 via a rotating shaft 14.

[0026] In actual use, the grinding roller in the grinding device 13 can be lowered by the cylinder. When it is lowered to the level with the side of the hardware, the grinding roller is moved close to the hardware, and then the grinding roller is driven to rotate by the motor to grind and remove burrs from the hardware. This is a mature existing technology and will not be repeated here.

[0027] The fixing component 2 includes a first threaded rod 21 rotatably connected to the inside of the rotating disk 15, the spiral directions of the threads on both sides of the first threaded rod 21 are opposite, and the threads on both sides of the first threaded rod 21 are threadedly fitted with a first clamping plate 22. Two second threaded rods 23 are rotatably connected to the inside of the rotating disk 15, and the two second threaded rods 23 are threadedly fitted with a second clamping plate 24. A bevel gear ring 25 is interference fit on the first threaded rod 21, and a bevel gear 26 is interference fit on the side of the two second threaded rods 23 close to the first threaded rod 21. The two bevel gears 26 are meshed with the two sides of the bevel gear ring 25.

[0028] Among them, the two first clamping plates 22 and the two second clamping plates 24 are extended to the top of the rotating disk 15, so that the two first clamping plates 22 and the two second clamping plates 24 can clamp and fix the hardware when they are close to the hardware in the center of the rotating disk 15.

[0029] Among them, four limiting grooves 151 are provided above the rotating disk 15, and the two first clamping plates 22 and the two second clamping plates 24 are respectively slidably connected to the inner walls of the four limiting grooves 151. The limiting grooves 151 can limit the clamping plates so that the clamping plates can only move along the predetermined track, while preventing them from rotating along the threaded rod.

[0030] Among them, the side walls of the two first clamping plates 22 and the two second clamping plates 24 close to the center of the rotating disk 15 are both wavy, so that the two first clamping plates 22 and the two second clamping plates 24 can better fix the hardware when they are close to the hardware.

[0031] One side of the first threaded rod 21 extends outside the rotating disk 15 and is fixedly connected to a knob.

[0032] It should be noted that before deburring, the hardware is placed on the rotating disk 15, and then the knob is turned. The rotation of the first threaded rod 21 drives the two first clamping plates 22 to approach each other. At the same time, the first threaded rod 21 drives the two second threaded rods 23 to rotate through the bevel gear ring 25 and the two bevel gears 26, so that the two second clamping plates 24 are also close to each other, clamping and fixing the hardware from all sides, preventing the hardware from moving during the grinding process, so that the grinding roller can squeeze and grind the hardware well, thereby improving the deburring effect of the hardware.

[0033] The driving assembly 3 includes a rotating rod 31 rotatably connected to the top of the base 1, a first gear 32 is interference fit on the rotating rod 31, and a second gear 33 is interference fit on the rotating shaft 14. The first gear 32 and the second gear 33 are engaged with each other. A motor 34 is provided below the base 1, and the output shaft of the motor 34 is fixedly connected to the rotating rod 31.

[0034] Among them, the radius of the first gear 32 is half of the radius of the second gear 33, so that when the motor 34 drives the rotating rod 31 to rotate two circles, the rotating disk 15 only rotates one circle, which reduces the rotation speed of the hardware on the rotating disk 15, allowing the grinding roller to remove burrs on the hardware more carefully, while avoiding excessive load on the motor 34 caused by excessive weight of the hardware.

[0035] It is worth mentioning that after the hardware is fixed, the motor 34 can drive the rotating rod 31 and the first gear 32 to rotate, and the second gear 33 can further drive the rotating disk 15 to rotate. When the hardware is polished, the rotation of the hardware can enable the polishing roller to comprehensively polish and remove burrs on the surrounding side walls of the hardware, thereby improving the deburring effect on the surrounding side walls of the hardware.

[0036] The functional principle of this utility model can be explained through the following operation modes:

[0037] During use, place the hardware in the center position of the rotating disk 15, and then rotate the first threaded rod 21 through the knob to make the two first clamping plates 22 approach each other. At the same time, the first threaded rod 21 drives the two second threaded rods 23 to rotate through the bevel gear ring 25 and the two bevel gears 26, so that the two second clamping plates 24 approach each other. When the four clamping plates are close to the hardware, the hardware can be clamped and fixed to prevent the hardware from moving during the grinding process. Then, move the grinding roller to close to the hardware, turn on the motor 34 and make the grinding roller start to rotate. The motor 34 drives the rotating rod 31 to rotate, and further drives the rotating disk 15 to rotate through the first gear 32 and the second gear 33, and the rotating grinding roller is used to fully grind the peripheral side walls of the hardware.

[0038] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
