DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Embodiment 1:

[0031] In this embodiment, the forging is polished and deburred by vibrating the abrasive in the vibrating plate 3. Figure 1 As shown:

[0032] A vibration plate 3 is connected to the upper part of the outer shell 2 of the vibration assembly, and a protective cover 5 is arranged on the inner side of the vibration plate 3. A connecting piece 4 is installed on the outer surface of the vibration plate 3, and a protective plate 6 is arranged on the upper part of the vibration plate 3.

[0033] When using the medical hip stem forging deburring device, first place the support base 1 of the device in a corresponding position, and arrange a vibration component outer shell 2 on the support base 1, and a vibration disk 3 is connected to the top of the vibration component outer shell 2, wherein the vibration component outer shell 2 includes a vibration machine base, a vibration motor, and an eccentric disk, which are known technologies on the market, and reference may be made to the patent with publication number CN207326686U. The use principle will not be described in too much detail, so the forging can be placed in the vibration disk 3, and then the forging can be polished and deburred by the abrasive vibration in the vibration disk 3.

[0034] Embodiment 2:

[0035] In this embodiment, a placement plate 14 is used to facilitate the placement of forgings, so that the forgings can be taken out after the later processing. Figure 2 and Figure 6 As shown:

[0036] The fixing plates 10 are distributed at equal angles, and a vibration spring 11 is installed between the fixing plates 10 and the bottom of the vibration disk 3, and the fixing plates 10 and the outer shell 2 of the vibration component are fixed by screws, a hydraulic rod 12 is installed on the top of the protective sleeve 5 by bolts, and the output end of the hydraulic rod 12 is connected to a mounting sleeve 13, and a placement plate 14 is installed on the outer surface of the mounting sleeve 13, there is a gap between the bottom of the mounting sleeve 13 and the vibration disk 3, a fixing groove 15 is opened on the placement plate 14, and the placement plate 14 and the mounting sleeve 13 are welded, and the placement plates 14 are distributed at equal intervals, and there is a gap between the placement plate 14 and the inner wall of the vibration disk 3;

[0037] When processing the forgings, the hydraulic rod 12 can be started first, and the hydraulic rod 12 will push the installation sleeve 13 to rise, and the installation sleeve 13 will drive the placement plate 14 to rise together. After the placement plate 14 rises to a suitable position, the forging to be processed is placed on the placement plate 14, and then the hydraulic rod 12 is reset and moved, thereby driving the placement plate 14 to descend, so that the forging will enter the vibration plate 3, and then the prepared abrasive is placed in the vibration plate 3. Because the placement plate 14 is provided with fixed grooves 15 distributed at equal angles, and the placement plates 14 are distributed at equal intervals, and there is a gap between the placement plate 14 and the inner wall of the vibration plate 3 interval, so when the abrasive is put in, the abrasive will flow from the fixed groove 15, so that the abrasive can smoothly enter the vibration plate 3, and then turn on the vibration motor in the vibration component outer shell 2, which will make the vibration plate 3 vibrate. The vibration of the vibration plate 3 will drive the abrasive and the forging to vibrate and move relative to each other, so that the friction between the abrasive and the forging can process the burrs on the forging, and achieve the effect of polishing and grinding the forging. In addition, a fixed plate 10 is installed on the outer wall of the vibration component outer shell 2, and a vibration spring 11 is installed between the fixed plate 10 and the vibration plate 3, so that the vibration effect of the vibration plate 3 can be better.

[0038] Embodiment three:

[0039] In this embodiment, it is disclosed that during the forging processing, the abrasive and the forging can be protected by the protective plate 6 to effectively prevent the overflow during the vibration process. Figure 3-Figure 5 As shown:

[0040] The outer surface of the outer shell 2 of the vibration assembly is provided with a fixing plate 10, and the inner side of the vibration plate 3 is provided with a placement structure for conveniently placing forgings, and the placement structure includes a placement plate 14;

[0042] When forging is processed, since the inner wall of the connecting piece 4 is provided with a limiting groove 9, and the size of the limiting groove 9 is consistent with the size of the positioning block 8 on the lower surface of the protective plate 6, the positioning block 8 on the lower surface of the protective plate 6 can be engaged into the limiting groove 9, so that the protective plate 6 and the connecting piece 4 can be installed. In this way, during the forging processing, the abrasive and the forging can be protected by the protective plate 6, and the overflow during the vibration process can be effectively prevented. When the forging is processed, the lever 7 can be pulled upward, and the lever 7 drives the protective plate 6 to move together to achieve the purpose of disassembling the protective plate 6, and then the hydraulic rod 12 is started. The hydraulic rod 12 will lift the installation sleeve 13, and the installation sleeve 13 will drive the placement plate 14 and the forging to rise together. This makes it easy to take the processed forgings, which brings convenience to the operation of the staff. The above is the working process of the entire device. The contents not described in detail in this manual belong to the existing technology known to professional and technical personnel in this field.
