DETAILED DESCRIPTION

[0021] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a surface grinding device for metal sealing ring processing, comprising a workbench 1, on which a grinding mechanism 2 is arranged, through which the grinding mechanism 2 can complete the grinding process of the outer wall of the sealing ring in pairs, a support rod 3 is fixedly installed on the workbench 1, a support plate 4 is fixedly installed on the support rod 3, a slide groove 5 is opened on the support plate 4, a fixing mechanism 6 is arranged on the support plate 4, and an anti-falling mechanism 7 is arranged on the fixing mechanism 6.

[0022] In this embodiment, a fixing mechanism 6 is provided on the support plate 4. The ring 64 in the fixing mechanism 6 moves upward to squeeze the bottom end of the support rod 65, so that the four groups of sliders 61 can expand outward at the same time. The sliders 61 drive the clamping plates 62 on the outer wall to squeeze the inner wall of the sealing ring to complete the fixation, which is convenient for clamping and fixing sealing rings of different sizes.

[0023] In this embodiment, an anti-falling mechanism 7 is provided on the fixing mechanism 6. The bottom end of the squeezing rod 73 in the anti-falling mechanism 7 is squeezed, so that the squeezing rod 73 can rotate around the rotating rod 71. The upper end of the squeezing rod 73 is rotated to the top of the sealing ring for protection, which can prevent the sealing ring from falling when the clamping plate 62 is expanded. At the same time, during the disassembly process, the elastic force of the torsion spring 72 can rotate and reset the squeezing rod 73, which is convenient for taking out the sealing ring to complete the processing.

[0024] The above-mentioned fixing mechanism 6 includes a slider 61, which is slidably connected to the inner wall of the slide groove 5. A clamping plate 62 is fixedly installed on the outer wall of the slider 61, and the clamping plate 62 is set in an arc shape. The sealing ring is fixed by sleeve-fitting the outer side of the four groups of clamping plates 62. A supporting column 63 is fixedly installed on the bottom wall of the support plate 4. A collar 64 is slidably sleeved on the outer wall of the support column 63. The position of the collar 64 can be fixed by screwing the fastening bolt 66. The internal thread of the collar 64 is connected with the fastening bolt 66. The collar 64 is hinged to one end of the support rod 65, and the other end of the support rod 65 is hinged to the bottom end of the slider 61. The collar 64 moves upward to squeeze the bottom end of the support rod 65, so that the four groups of sliders 61 can expand outward at the same time. The slider 61 drives the clamping plate 62 on the outer wall to squeeze the inner wall of the sealing ring to complete the fixation.

[0025] The above-mentioned anti-falling mechanism 7 includes a rotating rod 71, which is rotatably connected to the inner wall of the clamping plate 62, the outer wall of the rotating rod 71 is fixedly connected to one end of a torsion spring 72, and the other end of the torsion spring 72 is fixedly connected to the inner wall of the clamping plate 62. The elastic force of the torsion spring 72 can make the extrusion rod 73 rotate and reset, so as to facilitate the removal of the sealing ring to complete the processing. The interior of the rotating rod 71 is fixedly penetrated by an extrusion rod 73, and the upper end of the extrusion rod 73 is rotated to the top of the sealing ring for protection, so as to prevent the sealing ring from falling when the clamping plate 62 is expanded. The extrusion rod 73 is arranged in a bent shape, and the bottom end of the extrusion rod 73 is squeezed by the sealing ring, so that the extrusion rod 73 can rotate around the rotating rod 71.

[0026] In this embodiment, when the sealing ring needs to be polished, the sealing ring is sleeved on the outer side of the four groups of clamping plates 62, and then the collar 64 is pushed upward to move upward, and the bottom end of the support rod 65 is squeezed by the upward movement of the collar 64, and then the four groups of sliders 61 are expanded outward at the same time through the hinge between the support rod 65 and the slider 61, and then the clamping plate 62 on the outer wall is driven by the slider 61 to squeeze the inner wall of the sealing ring to complete the fixation, and finally the position of the collar 64 is fixed by tightening the fastening bolt 66, and while the clamping plate 62 clamps the inner wall of the collar 64, The sealing ring squeezes the bottom end of the extrusion rod 73, thereby causing the extrusion rod 73 to rotate around the rotating rod 71, and then the upper end of the extrusion rod 73 rotates to the top of the sealing ring for protection, preventing the sealing ring from falling when the clamping plate 62 is expanded. Finally, the grinding process of the outer wall of the sealing ring is completed by the set grinding mechanism 2. After grinding, the fastening bolts 66 are loosened, and then the ring 64 is pulled downward to drive the bottom end of the support rod 65 to move downward, so that the slider 61 drives the clamping plate 62 to reset, and then the elastic force of the torsion spring 72 is used to rotate and reset, so that it is easy to remove the sealing ring to complete the processing.
