[0001] The present application relates to the technical field of rotor production and grinding, in particular to a rotor external circle grinding machine with grinding protection function. BACKGROUND

[0002] Rotor grinding background technology mainly involves surface treatment and repair of the core component-rotor of rotating machinery such as motors and turbines. Traditional methods include manual grinding and lathe processing, but there are problems such as low efficiency, poor precision, and easy damage to the substrate. With the development of industry, automated grinding technology (such as CNC grinding machine, laser grinding) has gradually become popular, improving the grinding accuracy and efficiency, but still faces 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;

[0004] The existing rotor grinding machine mainly has the following shortcomings:

[0005] When grinding the rotor, debris will be generated, and if the debris is not removed in time, it will cause scratches on the surface of the rotor during grinding, affecting the product quality. SUMMARY

[0015] The grinding disc protective cover is arranged on the outer side of the grinding disc, and 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, and the driving shaft is concentrically arranged with the grinding disc. The other end of the driving shaft is fixedly connected to one end of the rotating rod, and the other end of the rotating rod is rotatably connected to the sliding block one. The sliding block one is slidably connected to the sliding groove one, and the sliding groove one is fixedly connected to one end of the L connecting rod one. The other end of the L connecting rod one is fixedly connected to the triangular moving table.

[0016] Two support rods are further fixedly connected to the grinding disc protective cover, and the upper ends of the two support rods are respectively fixedly connected to the two ends of the sliding block two. The lower end of the triangular moving table is provided with a sliding groove two, and the sliding block two is slidably connected to the sliding groove two.

[0017] Further, the vibration debris removal assembly comprises:

[0018] Two L connecting rods two are respectively fixedly connected to the two sides of the upper end of the grinding disc protective cover, and the other ends of the two L connecting rods two are respectively rotatably connected to the two clamping jaws. A torsional spring is fixedly connected to the position where the clamping jaw is rotatably connected to the L connecting rod two. One end of the clamping jaw is rotatably connected to the roller one, and the two rollers one are respectively abutted to the two sides of the triangular moving table. The cleaning brush is fixedly connected to the opposite position of the two clamping jaws.

[0019] Further, the rebound assembly comprises:

[0020] The sleeve is slidably connected to the grinding disc protective cover. One end of the sleeve is fixedly connected to the V-shaped rod, and the two ends of the V-shaped rod are respectively rotatably connected to the roller two. The sleeve is provided with a threaded structure, and the sleeve is threadedly connected to the lead screw. One end of the lead screw is fixedly connected to the spring, and the other end of the spring is fixedly connected to the grinding disc protective cover.

[0021] Further, the display assembly comprises:

[0022] The sliding rod is fixedly connected with the lead screw at one end, and is slidably connected with the sliding groove three at the other end, the sliding groove three is fixedly connected with the pointer at one end, the grinding disc protective cover is fixedly connected with the fixed shaft, the sliding groove three is rotatably connected with the fixed shaft, and the top end of the fixed shaft is fixedly connected with the protractor.

[0023] Compared with the prior art, the above one or more technical solutions have the following beneficial effects:

[0024] 1. The triangular mobile platform reciprocates, so that the rollers on both sides of the triangular mobile platform are squeezed, and then the clamping jaws on both sides are rotated, that is, when the triangular mobile platform moves towards the rotor, the clamping jaws on both sides are rotated, the cleaning brushes on the clamping jaws on both sides are close to each other, and when the triangular mobile platform moves away from the rotor, the cleaning brushes on the clamping jaws on both sides are away from each other under the action of the torsional spring until the torsional spring resets, and the triangular mobile platform moves to the farthest position. In this process, the cleaning brushes move towards or away from the rotor, realize reciprocating movement within a certain range, realize vibration effect, clean the debris on the surface of the rotor, generate vibration through the reciprocating movement of the cleaning brushes, effectively remove stubborn debris such as metal powder and oil stains, effectively clean the debris generated during polishing, avoid scratches caused by debris during polishing of the rotor, and effectively improve product quality.

[0025] 2. The triangular mobile platform reciprocates, and the reciprocating distance of the triangular mobile platform is fixed. When the triangular mobile platform moves towards the rotor, the sleeve, the lead screw, the spring, the V-shaped rod and the roller two move towards the rotor together, so that the roller two abuts against the outer surface of the rotor. When continuing to move, the spring is compressed, and the sleeve and the lead screw slide. After the surface of the rotor is polished, the compression distance of the spring becomes smaller, and the sliding distance of the sleeve and the lead screw becomes smaller. Through the thread cooperation of the sleeve and the lead screw, the distance between the roller two and the rotor is adjusted by rotating the lead screw. Combined with the fact that the moving distance of the triangular mobile platform is fixed, the demand for various diameters of the rotor can be met. The sliding of the lead screw drives the sliding rod to move backwards, and then the sliding groove three drives the pointer to rotate on the fixed shaft three. The polishing degree of the rotor can be obtained by the number on the protractor pointed by the pointer. Combined with the diameter of the rotor before polishing, the diameter of the polished rotor can be obtained by the angle of the pointer deflection. The spring automatically adjusts the compression amount to ensure the stability of the polishing pressure and avoid over-polishing or under-polishing. BRIEF DESCRIPTION OF DRAWINGS
