Description

Technical Field

[0001] This utility model belongs to the field of machining fixture technology, and more specifically, it relates to a machining fixture for a sealing ring. Background Technology

[0002] Currently, Chinese patent CN219967578U discloses a machining fixture for sealing rings, including a mounting plate. A disc is movably mounted on the top of the mounting plate, and a groove is formed on the top of the disc. A movable block is movably fitted inside the groove, and a clamping block is movably mounted on the outside of the movable block. A slot is formed inside the movable block, and the bottom of the clamping block penetrates the movable block and extends into the slot. A mounting rod is fixedly mounted on the inner wall of the slot, and a moving block is movably fitted on the outer surface of the mounting rod. The front of the moving block extends to the outside of the slot, and a clamping block is mounted on the inner side of the moving block. The inner side of the clamping block penetrates the movable block and extends into the inner cavity of the clamping block. A spring is fixedly connected to the outer side of the moving block. This allows the operator to easily clamp sealing rings of different sizes by changing the clamping block, thus facilitating the machining process.

[0003] While this type of clamp can quickly clamp sealing rings, it is not stable enough during actual grooving processing. It lacks sufficient external support, is prone to deformation, is not safe enough, and requires manual clamping and loosening, which is very time-consuming and labor-intensive, and cannot meet the needs of large-scale processing operations.

[0011] This utility model provides a machining fixture for sealing rings, which has the following beneficial effects:

[0012] By setting multiple mounting slots of different specifications on the processing plate, sealing rings of different specifications can be placed independently. At the same time, a micro motor drives the first bevel gear on the rotating shaft to rotate. The first bevel gear drives the second bevel gear meshing with it to rotate, so that the screw rotates and drives the top block to push out, thereby quickly positioning the inner ring of the sealing ring and realizing the first stage of clamping. When the processing plate is driven to rise by the electric cylinder, the adjusting pressure rod on the lifting frame will rise, causing the side pressure block to retract, which is to release. When the processing plate descends, the adjusting pressure rod on the lifting frame will descend, causing the side pressure block to push out, which is to clamp, quickly clamping the outer side of the sealing ring. A buffer chamber is set at one end of the side pressure block. When the side pressure block is clamped, the lower pressure block can fix the upper surface of the positioning ring, preventing the positioning ring from shaking during processing and affecting product quality.

The lifting mechanism includes an electric cylinder 14, which is fixed to the base 1. The extension end of the electric cylinder 14 is connected to a lifting frame 15. A guide rod 151 is provided at the top of the lifting frame 15. The guide rod 151 is slidably engaged in the worktable 3 and connected to the processing plate 5 at the top. At the same time, multiple clamping seats 4 are arranged around the processing plate 5. The multiple clamping seats 4 are circumferentially distributed and each of the multiple clamping seats 4 is provided with a clamping mechanism.

[0023] The clamping mechanism includes a side pressure block 402, which has a square hole. An adjusting wheel 403 is mounted in the square hole via a pin. An adjusting rod 401 is attached to one side of the adjusting wheel 403. The top of the adjusting rod 401 has an inclined surface for pressing the side pressure block 402 to move it. The adjusting rod 401 is slidably fitted in the square hole. The bottom of the adjusting rod 401 is movably connected to the lifting frame 15 of the lifting mechanism via a pin. The lifting frame 15 is driven by an electric cylinder 14 to move up and down, thereby causing the adjusting rod 401 to rise and fall. The adjusting rod 401 presses the adjusting wheel 403, thereby causing the side pressure block 402 to move forward. The side pressure block 402 is now compressed. A buffer chamber is provided inside one end of the side pressure block 402. A lower pressure block 4021 is provided inside the buffer chamber. The lower pressure block 4021 has a T-shaped cross section and a rounded chamfer at the bottom. The lower pressure block 4021 extends to the bottom of the side pressure block 402. Multiple springs 4022 are provided on the top of the lower pressure block 4021. The multiple springs 4022 are fixed in the buffer chamber, thereby fixing and limiting the surface of the sealing ring 6. Multiple chip removal holes 301 are also provided on the surface of the worktable. The multiple chip removal holes 301 are circumferentially distributed and have an arc shape, which are used to remove the iron chips generated by the grooving of the sealing ring 6. A positioning mechanism is also provided in the center of the processing disc 5.

[0024] The positioning mechanism includes a positioning seat 7, a micro motor 8 on the top of the positioning seat 7, a rotating shaft 10 connected to the drive end of the micro motor 8, a first bevel gear 11 mounted on the rotating shaft 10, and multiple second bevel gears 12 meshing on one side of the first bevel gear 11. The first bevel gear 11 drives the multiple second bevel gears 12 to rotate in the same direction. Each second bevel gear 12 is equipped with a screw 131.

The base 1 has multiple mounting holes 101 with U-shaped openings for easy overall installation.

[0025] The specific usage and function of this embodiment: The operator places the sealing ring 6 in the mounting groove of the processing plate 5. According to the different specifications of the sealing ring 6, it is placed in the mounting groove of the corresponding diameter specification. The micro motor 8 is started, which drives the first bevel gear 11 on the rotating shaft 10 to rotate. The first bevel gear 11 simultaneously drives the second bevel gear 12 meshing with it to rotate, so that the screw 131 rotates and drives the top block 9 to push out, thereby quickly positioning the inner ring of the sealing ring. Then, the electric cylinder 14 is started, which drives the lifting frame 15 to move up and down. The lifting frame 15 drives the top guide rod 151 to move up and down. When the processing plate 5 rises, the adjusting pressure rod 401 on the lifting frame 15 will rise, so that the side pressure block 402 retracts, which is to release. When the processing plate 5 falls, the adjusting pressure rod 401 on the lifting frame will fall, so that the side pressure block 402 pushes out, which is to clamp, quickly clamping the outside of the sealing ring 6. After clamping is completed, the whole is moved to the processing area and bolted through the mounting hole 101 on the base plate.
