Description

Technical Field

[0001] The present invention relates to the technical field of rotor production and grinding, and particularly to an external grinding machine for rotors with a grinding protection function. Background Art

[0002] The background technology of rotor grinding mainly involves the surface treatment and repair of the core components of rotating machinery such as motors and turbines - rotors. Traditional methods include manual grinding, lathe machining, etc., but there are problems such as low efficiency, poor accuracy, and easy damage to the matrix. With the development of industry, automated grinding technologies (such as CNC grinders, laser grinding) have gradually become popular, improving the grinding accuracy and efficiency, but still facing challenges such as high cost and limited adaptability. In recent years, intelligent grinding technology has become a research hotspot, aiming to achieve higher-precision and lower-cost rotor repair; An existing internal grinding machine for steel pipes with the publication number of CN112171402B includes a track, a first trolley and a second trolley arranged on the track. A supporting wheel for supporting and driving the steel pipe to rotate is arranged on the first trolley. A lifting column, a connecting piece and a sleeve connected to the connecting piece are arranged on the second trolley. A first rotating shaft is arranged in the sleeve. The first rotating shaft is connected with a worm, and the worm meshes with a worm gear. The worm gear penetrates through the second rotating shaft. The second rotating shaft is connected with the sleeve through a parallel beam sensor. A clamping mechanism is also arranged in the sleeve; in the present invention, the axis of the grinding wheel is perpendicular to the axis of the first rotating shaft. The first rotating shaft only receives the bending moment in the vertical plane and will not receive the bending moment in the horizontal plane. Under the support of the sleeve, the first rotating shaft is prevented from bending in the vertical plane; and the parallel beam sensor can detect the pressure of the grinding wheel on the inner wall of the steel pipe, so that the grinding wheel has a suitable grinding amount on the inner wall of the steel pipe, avoiding excessive pressure from affecting the size of the inner diameter of the steel pipe; The existing rotor grinding machines mainly have the following disadvantages: When grinding the rotor, debris will be generated. If the generated debris is not removed in time, it will cause scratches on the rotor surface during grinding, affecting the product quality. Summary of the Invention

[0005] Further, the rough grinding part grinds the outer circle of the rotor through a grinding disc; and The reciprocating sliding assembly includes: A grinding disc protective cover, which is arranged outside the grinding disc, the grinding disc protective cover is fixedly connected to the base of the grinding machine body, the upper end of the grinding disc is fixedly connected to one end of the driving shaft, the driving shaft is concentric with the grinding disc, the other end of the driving shaft is fixedly connected to one end of the rotating rod, the other end of the rotating rod is rotatably connected to the first slider, the first slider is slidably connected to the first chute, the first chute is fixedly connected to one end of the first L-shaped connecting rod, and the other end of the first L-shaped connecting rod is fixedly connected to the triangular moving table; and Two support rods are also fixedly connected to the grinding disc protective cover, the upper ends of the two support rods are respectively fixedly connected to both ends of the second slider, a second chute is opened at the lower end of the triangular moving table, and the second slider is slidably connected to the second chute.

[0006] Further, the vibration chip removal assembly includes: Two second L-shaped connecting rods, one end of each of the two second L-shaped connecting rods is respectively fixedly connected to both sides of the upper end of the grinding disc protective cover, the other end of each of the two second L-shaped connecting rods is respectively rotatably connected to two clamping jaws, a torsion spring is fixedly connected to the position where the clamping jaw is rotatably connected to the second L-shaped connecting rod, a first roller is rotatably connected to one end of the clamping jaw, the two first rollers are respectively abutted against both sides of the triangular moving table, and a cleaning brush is fixedly connected to the opposite position of the two clamping jaws.

[0007] Further, the spring-back assembly includes: A sleeve, the sleeve is slidably connected to the grinding disc protective cover, one end of the sleeve is fixedly connected to a V-shaped rod, two second rollers are respectively rotatably connected to both ends of the V-shaped rod, a threaded structure is opened in the sleeve, the sleeve is in threaded cooperation with a lead screw, one end of the lead screw is fixedly connected to a spring, and the other end of the spring is fixedly connected to the grinding disc protective cover.

[0008] Further, the display assembly includes: A sliding rod, one end of the sliding rod is fixedly connected to the lead screw through a bolt, the other end of the sliding rod is slidably connected to a third chute, a pointer is fixedly connected to one end of the third chute, a fixed shaft is fixedly connected to the grinding disc protective cover, the third chute is rotatably connected to the fixed shaft, and a protractor is fixedly connected to the top of the fixed shaft.

[0009] Compared with the prior art, the above one or more technical solutions have the following beneficial effects: 1. By reciprocating the triangular moving platform, the rollers on both sides of the triangular moving platform are squeezed, and then the clamping jaws on both sides rotate. That is, when the triangular moving platform moves towards the rotor, the clamping jaws on both sides rotate, and the cleaning brushes on the two clamping jaws approach each other until they contact the rotor. When the triangular moving platform moves away from the rotor, under the action of the torsion spring, the cleaning brushes on the two clamping jaws move away from each other until the torsion spring resets and the triangular moving platform moves to the farthest position. During this process, the cleaning brushes move towards or away from the rotor, realizing the reciprocating movement of the cleaning brushes within a certain range, achieving a vibration effect, cleaning the debris on the surface of the rotor. The reciprocating movement of the cleaning brushes generates vibration, effectively removing stubborn debris such as metal powder and oil stains, effectively cleaning the debris generated during grinding, avoiding the risk of scratches caused by debris during rotor grinding, and effectively improving product quality.

[0010] 2. By reciprocating the triangular moving platform, the reciprocating distance of the triangular moving platform is fixed during this process. When the triangular moving platform moves towards the rotor, it drives the sleeve, screw rod, spring, V-shaped rod, and roller two to move towards the rotor together, making the roller two abut against the outer surface of the rotor. When moving further, the spring is compressed, and the sleeve and screw rod slide. When the surface of the rotor is ground, the compressed distance of the spring becomes smaller, and at the same time, the sliding distance of the sleeve and screw rod becomes smaller. Through the threaded cooperation between the sleeve and the screw rod, by rotating the screw rod, the distance between the roller two and the rotor is adjusted. Combining with the fixed moving distance of the triangular moving platform, the requirements for various rotor diameters can be met. The sliding of the screw rod drives the sliding rod to move backward together, and then the chute three drives the pointer to rotate on the fixed shaft three. By the number pointed to by the pointer on the protractor, the grinding degree of the rotor can be obtained. Combining with the diameter of the rotor before grinding, the diameter of the rotor after grinding can be obtained through the deflection angle of the pointer. The spring automatically adjusts the compression amount to ensure stable grinding pressure and avoid over-grinding or under-grinding. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] To enable those skilled in the art to better understand the solution of this application, the following will clearly and completely describe the technical solution in the embodiments of this application in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

[0015] Referring to Figure 1-4 As shown, a rotor outer circle grinding machine with grinding protection function includes a grinding machine body 1. The grinding machine body 1 includes a rough grinding part 11 and a fine grinding part 12. A chip removal mechanism 2 is fixedly connected to the rough grinding part 11, and a diameter monitoring mechanism 3 is fixedly connected to the chip removal mechanism 2. The chip removal mechanism 2 includes: A reciprocating sliding component 21, which is fixedly connected to the rough grinding part 11. A vibration chip removal component 22 is rotatably connected to the reciprocating sliding component 21. The diameter monitoring mechanism 3 includes: A rebound component 31, which is slidably connected to a display component 32. The display component 32 is rotatably connected to the reciprocating sliding component 21.

[0016] When the rotor is ground on the rough grinding part 11, the reciprocating sliding component 21 drives the vibration chip removal component 22 to vibrate to remove the chips on the surface of the rotor. At the same time, the reciprocating sliding component 21 drives the rebound component 31 to approach or move away from the rotor and reciprocate to measure the outer diameter of the rotor.

[0017] Referring to Figure 5-7 As shown, the rough grinding part 11 grinds the outer circle of the rotor through a grinding disc 111; and The reciprocating sliding component 21 includes: A grinding disc protective cover 211, which is arranged outside the grinding disc 111. The grinding disc protective cover 211 is fixedly connected to the base of the grinding machine body 1. The upper end of the grinding disc 111 is fixedly connected to one end of a driving shaft 212. The driving shaft 212 is concentric with the grinding disc 111. The other end of the driving shaft 212 is fixedly connected to one end of a rotating rod 213. The other end of the rotating rod 213 is rotatably connected to a slider one 214. The slider one 214 is slidably connected to a chute one 215. The chute one 215 is fixedly connected to one end of an L connecting rod one 216. The other end of the L connecting rod one 216 is fixedly connected to a triangular moving table 217; and Two support rods 218 are also fixedly connected to the grinding wheel protective cover 211. The upper ends of the two support rods 218 are respectively fixedly connected to both ends of the second slider 219. A second chute 2171 is formed at the lower end of the triangular moving platform 217. The second slider 219 is slidably connected to the second chute 2171.

[0018] When the grinding wheel 111 grinds the rotor, the rotation of the grinding wheel 111 drives the rotation of the driving shaft 212, and then drives the rotation of the rotating rod 213 fixedly connected to the upper end of the driving shaft 212. When the first slider 214 slides on the first chute 215, it pushes the first chute 215, the first L connecting rod 216 and the triangular moving platform 217 to reciprocate. The triangular moving platform 217 reciprocates relative to the second slider 219 through the second chute 2171.

[0019] Refer to Figure 8 As shown in the figure, the vibration chip removal assembly 22 includes: Two second L connecting rods 221. One ends of the two second L connecting rods 221 are respectively fixedly connected to both sides of the upper end of the grinding wheel protective cover 211. The other ends of the two second L connecting rods 221 are respectively rotatably connected to two clamping jaws 222. A torsion spring 223 is fixedly connected to the position where the clamping jaw 222 is rotatably connected to the second L connecting rod 221. One end of the clamping jaw 222 is rotatably connected to a first roller 224. The two first rollers 224 are respectively abutted against both sides of the triangular moving platform 217. A cleaning brush 225 is fixedly connected to the opposite positions of the two clamping jaws 222.

[0020] Through the reciprocating movement of the triangular moving platform 217, the first rollers 224 on both sides of the triangular moving platform 217 are squeezed, and then the two clamping jaws 222 rotate. That is, when the triangular moving platform 217 moves towards the rotor, the two clamping jaws 222 rotate, and the cleaning brushes 225 on the two clamping jaws 222 approach each other until they contact the rotor. When the triangular moving platform 217 moves away from the rotor, under the action of the torsion spring 223, the cleaning brushes 225 on the two clamping jaws 222 move away from each other until the torsion spring 223 resets, and the triangular moving platform 217 moves to the farthest position. During this process, the cleaning brush 225 moves towards or away from the rotor, realizing the reciprocating movement of the cleaning brush 225 within a certain range, achieving the vibration effect, and cleaning the debris on the surface of the rotor.

[0021] Refer to Figure 10 As shown in the figure, the rebound assembly 31 includes: A sleeve 311 is slidably connected to the grinding disc protective cover 211. One end of the sleeve 311 is fixedly connected to a V-shaped rod 312. Two rollers 313 are respectively rotatably connected to both ends of the V-shaped rod 312. A threaded structure is provided inside the sleeve 311. The sleeve 311 and a lead screw 314 are in threaded cooperation. One end of the lead screw 314 is fixedly connected to a spring 315, and the other end of the spring 315 is fixedly connected to the grinding disc protective cover 211.

[0022] The triangular moving platform 217 reciprocates. During this process, the reciprocating movement distance of the triangular moving platform 217 is fixed. When the triangular moving platform 217 moves towards the rotor, it drives the sleeve 311, the lead screw 314, the spring 315, the V-shaped rod 312 and the two rollers 313 to move towards the rotor together, so that the two rollers 313 are in contact with the outer surface of the rotor. When continuing to move, the spring 315 is compressed, and the sleeve 311 and the lead screw 314 slide. When the surface of the rotor is polished, the compressed distance of the spring 315 becomes smaller, and at the same time, the sliding distance of the sleeve 311 and the lead screw 314 becomes smaller. Through the threaded cooperation between the sleeve 311 and the lead screw 314, by rotating the lead screw 314, the distance between the two rollers 313 and the rotor is adjusted. Combining with the fixed movement distance of the triangular moving platform 217, the requirements for various rotor diameters can be met.

[0023] Refer to Figure 9 As shown, the display assembly 32 includes: A slide bar 321. One end of the slide bar 321 is fixedly connected to the lead screw 314 by a bolt. The other end of the slide bar 321 is slidably connected to a third chute 322. One end of the third chute 322 is fixedly connected to a pointer 323. A fixed shaft 324 is fixedly connected to the grinding disc protective cover 211. The third chute 322 is rotatably connected to the fixed shaft 324. A protractor 325 is fixedly connected to the top of the fixed shaft 324.

[0024] The sliding of the lead screw 314 drives the slide bar 321 to move backward together, thereby causing the third chute 322 to drive the pointer 323 to rotate on the fixed shaft 324. By the number pointed to by the pointer 323 on the protractor 325, the grinding degree of the rotor can be obtained. Combining with the diameter of the rotor before grinding, the diameter of the rotor after grinding can be obtained through the deflection angle of the pointer 323.
