[0012] The present invention provides a chamfering tool for machining a positioning ring, which has the following beneficial effects: 1. The present invention ensures stable pressure when the chamfering and grinding of the positioning ring is performed by the first hinge block by setting a chamfering mechanism, and also avoids the problem that when the fixed first hinge block is chamfering and grinding the positioning ring, the first hinge block over-extrudes the chamfer of the positioning ring, causing damage and deformation due to improper control of the position distance between the positioning ring and the first hinge block, and also avoids the problem of insufficient grinding force due to low mutual pressure. The first hinge block automatically applies pressure to the outer wall of the positioning ring through different rotation speeds, and the grinding of the chamfer of the positioning ring is completed step by step from small to large; 2. The present invention sets a grinding mechanism. When the first hinge block rotates, the long plate and the arc strip on the first hinge block complete the grinding of the chamfer of the positioning ring. The arc strip is an arc surface, which makes the grinding of the chamfer of the positioning ring more stable and reduces the burr problem. At the same time, the long plate itself is also inclined. The long plate drives the arc strip to rotate and grind the chamfer of the positioning ring in an inclined manner. The inclination makes the angle between the long plate and the arc strip in the grinding direction of the positioning ring less than ninety degrees, which avoids the problem of excessive pressure, deformation and damage caused by the arc strip directly pressing against the chamfer of the positioning ring when there are burrs and unevenness at the chamfer of the positioning ring. 3. The present invention sets a grinding mechanism and controls the distance between the slider and the second motor through an electric telescopic machine, so that when the long plate and the arc strip are rotating, different positions of the outer wall of the arc strip can abut against the chamfer of the positioning ring, so that grinding can be performed at a faster speed. At the same time, the initial end and the end of the arc strip can be used to grind the positioning ring with different force arms, so that the speed can be adjusted and the pressure of the arc strip and the positioning ring can be adjusted, and they can be adjusted freely without affecting each other; 4. The present invention provides a grinding mechanism. Since the long plate is set to an inclined setting, when the long plate rotates, the long plate will stir the surrounding air to make the air flow. The air flows to the positioning ring and takes away the waste residue generated by the grinding chamfer in real time, thereby avoiding the problem of reduced grinding accuracy caused by the waste residue adhering to the arc strip and the outer wall of the positioning ring; 5. The present invention sets an auxiliary mechanism. When the sliding plate slides outward, the sliding distance of the sliding plate can be observed in real time through several grooves provided on the outer wall of the sliding plate and the position of the outer wall of the connecting head at this time. Then, the clamping angle of the arc strip to the positioning ring can be judged to a certain extent, which is convenient for the operator to observe and make subsequent timely adjustments.

DETAILED DESCRIPTION
[0015] Example 1: Please refer to Figure 1-4 The present invention provides a technical solution: a chamfering tool for positioning ring processing, comprising a table 5, a supporting leg 1 is fixedly connected to the bottom of the table 5, a processing seat 6 is fixedly connected to the top of the table 5, a first motor 7 is fixedly connected to the top of the processing seat 6, a positioning ring 8 is arranged at one end of the first motor 7, a slider 10 is arranged at the top of the processing seat 6, an electric telescopic machine 9 is arranged on one side of the slider 10, the electric telescopic machine 9 is fixedly connected to the inner wall of the processing seat 6, a second motor 11 is fixedly connected to the top of the slider 10, and a chamfering mechanism 2 is arranged on one side of the second motor 11; The chamfering mechanism 2 comprises: The connecting shaft 201 is a circular rod-shaped structure. One end of the connecting shaft 201 is fixedly connected to a connecting head 202. A sliding groove is provided on the inner wall of the connecting head 202. The connecting head 202 is slidably connected to a sliding plate 203 through the sliding groove on the inner wall. The sliding plate 203 is used to slide outward when the connecting head 202 rotates. Push plate 205, push plate 205 is a square plate structure, one side of push plate 205 is fixedly connected to the outer wall of sliding plate 203, one side of push plate 205 is fixedly connected to a fixed block 206, one side of fixed block 206 is fixedly connected to a spring 207, one end of spring 207 is fixedly connected to a first hinge block 208, and the first hinge block 208 is used to chamfer the positioning ring 8.
[0016] The inner wall of the first hinge block 208 is rotatably connected to a rotating shaft 209, and the outer wall of the rotating shaft 209 is fixedly connected to a second hinge block 210. One side of the second hinge block 210 is fixedly connected to the outer wall of the connector 202. The rotating shaft 209 is used to play the role of free rotation of the first hinge block 208; When in use, the positioning ring 8 is fixed on one side of the first motor 7, and then the electric telescopic machine 9 is started to control the slider 10 on the processing seat 6 to move, and the position of the second motor 11 is adjusted so that the connecting shaft 201 on the output end of the second motor 11 is close to the positioning ring 8, and the second motor 11 is started to drive the connecting shaft 201 and the connecting head 202 to rotate. The rotation of the connecting head 202 drives the external first hinge block 208 to rotate. When the first hinge block 208 rotates, the chamfer of the positioning ring 8 is polished through its outer wall, completing the work of polishing the chamfer of the positioning ring 8; By means of the rotary grinding of the first hinge block 208, the sliding plate 203 in the inner wall of the connector 202 is thrown outwards by the centrifugal effect of its rotation. When the sliding plate 203 slides outwards, it will simultaneously push the push plate 205 and the fixed block 206 outwards. The fixed block 206 pulls the first hinge block 208 through the spring 207. When one side of the first hinge block 208 is pulled, one end of the first hinge block 208 is hinged to the second hinge block 210 through the rotating shaft 209, so that the first hinge block 208 performs an articulated rotation movement on the inner wall of the second hinge block 210 through the rotating shaft 209. When the first hinge block 208 is hinged and rotated, the first hinge block 208 will rotate. When the first hinge block 208 rotates, the side of the first hinge block 208 that is close to the positioning ring 8 will be pressed tighter, so that the first hinge block 208 will complete the automatic pressure on the chamfer of the positioning ring 8, thereby ensuring the stable pressure effect when the first hinge block 208 is used to chamfer and grind the positioning ring 8, and also avoiding the problem that the first hinge block 208 over-extrudes the chamfer of the positioning ring 8 and causes damage and deformation due to improper control of the position distance between the positioning ring 8 and the first hinge block 208 when the fixed first hinge block 208 is used to chamfer and grind the positioning ring 8, and also avoiding the problem that the grinding force is insufficient due to the small pressure between each other. The first hinge block 208 automatically applies pressure to the outer wall of the positioning ring 8 by different rotation speeds, and the grinding effect of the chamfer of the positioning ring 8 is gradually completed from small to large. Example 2: Please refer to Figure 1-8 On the basis of the first embodiment, the present invention provides a technical solution: a grinding mechanism 3 is provided on one side of the first hinge block 208, and the grinding mechanism 3 includes a long plate 301, one end of the long plate 301 is fixedly connected to one side of the first hinge block 208, and the long plate 301 is used to be driven by the first hinge block 208 to rotate together.
[0017] An arc strip 302 is fixedly connected to one side of the long plate 301 , and the arc strip 302 is used to grind the outer wall of the positioning ring 8 .
[0018] The long plate 301 is an inclined plate-like structure, and the long plate 301 is inclined. The inclined setting of the long plate 301 is used to move the air flow; When the first hinge block 208 rotates, the long plate 301 and the arc strip 302 on the first hinge block 208 complete the grinding of the chamfer of the positioning ring 8, and the arc strip 302 is a curved surface, which makes the grinding of the chamfer of the positioning ring 8 more stable and reduces the burr problem. At the same time, the long plate 301 itself is also inclined, and the long plate 301 drives the arc strip 302 to rotate and grind the chamfer of the positioning ring 8 in an inclined manner. The inclination makes the angle between the long plate 301 and the arc strip 302 in the grinding direction of the positioning ring 8 less than ninety degrees, which avoids the arc strip 302 directly pressing against the chamfer of the positioning ring 8 when there are burrs and unevenness at the chamfer of the positioning ring 8, thereby causing the problem of excessive pressure, deformation and damage; By controlling the distance between the slider 10 and the second motor 11 through the electric telescopic machine 9, the long board 301 and the arc strip 302 can be rotated so that different positions of the outer wall of the arc strip 302 can abut against the chamfer of the positioning ring 8, so that grinding can be performed at a faster speed. At the same time, the initial end and the end of the arc strip 302 can be used to grind the positioning ring 8 with different force arms, so that the speed can be adjusted and the pressure between the arc strip 302 and the positioning ring 8 can be adjusted without affecting each other, so that they can be adjusted freely. Example 3: Please refer to Figure 1-11 On the basis of the first and second embodiments, the present invention provides a technical solution: the outer wall of the sliding plate 203 is provided with an auxiliary mechanism 4, the auxiliary mechanism 4 includes a groove 401, the groove 401 is opened on the outer wall of the sliding plate 203, and the groove 401 is a square groove.
[0019] A spring 402 is fixedly connected to one side of the sliding plate 203 . The spring 402 has elastic force, and one end of the spring 402 is fixedly connected to the inner wall of the connecting head 202 .
[0020] The fixing block 206 is a square block structure, and the fixing block 206 is fixedly connected to the center position of one side of the push plate 205; When the sliding plate 203 is rotated by the connector 202, the spring 402 is pulled to deform, thereby pushing the push plate 205 outward. At the same time, when the sliding plate 203 slides outward, the sliding distance of the sliding plate 203 can be observed in real time through the several grooves 401 opened on the outer wall of the sliding plate 203 and the position of the outer wall of the connector 202 at this time, and then the clamping angle of the arc strip 302 to the positioning ring 8 at this time can be judged to a certain extent, which is convenient for the operator to observe and make subsequent timely adjustments; And because the long plate 301 is set to be inclined, when the long plate 301 rotates, the long plate 301 will stir the surrounding air, causing the air to flow. The air flows to the positioning ring 8 and takes away the waste residue generated by the grinding and chamfering in real time, thereby avoiding the problem of reduced grinding accuracy caused by the waste residue adhering to the outer wall of the arc strip 302 and the positioning ring 8.
[0021] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
