[0030] The fixing mechanism 8 includes a base 801, one side of the base 801 is fixedly connected to the inner wall of the electric wheel 2, a connecting hole 802 is provided on the side of the base 801 close to the electric wheel 2, and the connecting hole 802 is a circular hole that passes through the base 801 from top to bottom, and the front side of the base 801 and the rear side of the base 801 are provided with plug holes 803, and the plug holes 803 are holes that pass through the base 801 from top to bottom, and the side wall of the base 801 is provided with threaded holes 804, and the threaded holes 804 are holes that pass through the outer side of the base 801 and the inside of the plug holes 803. The upper side of the base 801 is a semicircular groove structure, and the inner wall of the groove is provided with an embedded hole, and a load-bearing wheel 805 is embedded in the embedded hole. Both ends of the load-bearing wheel 805 are rotatably connected to the inner wall of the embedded hole through bearings, and one side of the load-bearing wheel 805 extends to the outer side of the base 801, and a limiting frame 806 is provided on the upper side of the base 801, and the lower end of the limiting frame 806 is plugged into the plug hole 80 Inside, the inner wall of the threaded hole 804 is threadedly connected with a threaded pile 807, one end of the threaded pile 807 contacts the outer wall of the limiting frame 806, the upper side of the limiting frame 806 is fixedly connected with a motor 808, the output end of the motor 808 is fixedly connected with a transmission wheel 809, the lower side of the transmission wheel 809 penetrates the limiting frame 806 and extends to the lower side of the limiting frame 806, the fixing mechanism 8 also includes an air pipe 810, one end of the air pipe 810 is fixedly connected with the inner wall of the connecting hole 802, the other end of the air pipe 810 penetrates the rubber sheet 5 and extends to the rear side of the rubber sheet 5, the rear side of the upper surface of the bottom bracket 1 is fixedly connected with an air pump 811, the input end of the air pump 811 is fixedly connected with one end of the air pipe 810 located at the rear side of the rubber sheet 5, the left side of the inner wall of the electric wheel 2 and the right side of the inner wall of the electric wheel 2 are both provided with a base 801, and the connection between the air pipe 810 and the base 801 is located on the side of the connecting hole 802 close to the inner wall of the electric wheel 2;
[0031] When grinding the axle, after opening the sealing door 401, take out the threaded pile 807 from the inside of the threaded hole 804, then take out the limiting frame 806 from the inside of the base 801, place the axle on the upper side of the base 801, then insert the limiting frame 806 back into the inside of the base 801, fix the threaded pile 807 back into the inside of the threaded hole 804, so that the limiting frame 806 and the base 801 limit the axle, and at this time, the outer wall of the load-bearing wheel 805 and the outer wall of the transmission wheel 809 limit the surface of the axle at three points, and then close the sealing door 401;
[0032] Since the rotation of the processing ring 3 is controlled by the electric wheels 2 installed on both sides of the processing ring, the electric wheels 2 can drive the processing ring to rotate by adjusting the rotation direction and speed of the internal motor thereof, and when the motor 808 is started to drive the transmission wheel 809 to rotate, the axle can rotate under the squeezing and friction of the transmission wheel 809, and the mechanical arm of the grinding operation extends from the wrapping tube 6 into the interior of the processing ring 3 to grind the surface of the axle. Since the axle can be moved, the movement range and angle of the mechanical arm can be reduced, so that the axle can be processed from various angles on the operating table. By controlling the speed and direction of the electric wheels 2, the processing ring 3 can realize multi-angle rotation, and the axle can be driven to rotate by the transmission wheel 809, ensuring that the grinding tool can reach every surface of the axle even though the moving space and angle are reduced, thereby improving the comprehensiveness and accuracy of the processing, and the movement range of the mechanical arm is reduced, which can prevent the grinding chips caused by certain angles from adhering to the sensing element of the mechanical arm;
[0033] During the grinding process, the processing area is protected by a protective system formed by a sealing mechanism 4 to prevent the overflow of grinding chips. The sealing door 401, the processing ring 3 and the rubber sheet 5 together form a semi-closed processing environment, thereby preventing the grinding chips from splashing out during the grinding process.
[0034] During the grinding process, the air pump 811 can evacuate air through the air pipe 810, so that the inside of the processing ring 3 can be air-intaken through the fixed pipe 402, so that negative pressure is generated at the connecting hole 802. Since the inside of the axle is a hollow structure, and the part of the axle that needs to be ground is the plane side of the middle differential case and the two ends of the axle that need to be connected with the connecting piece, negative pressure is generated at the connecting hole 802, which will cause negative pressure at both ends of the axle, thereby generating suction inward in the middle of the axle, so that when the middle of the axle is ground, the grinding chips can be smoothly sucked away by the connecting hole 802 through the inside of the axle, and when the two ends of the axle are ground, they can also be sucked by the connecting hole 802. The grinding chips can be discharged into the collection device after passing through the air pump 811, thereby completing the collection of the grinding chips and avoiding pollution to the outside world.
[0035] In addition, when the fixed pipe 402 inputs the airflow into the machining ring 3, the airflow is guided by the airflow guide plate 403, so that the airflow rotates at a high speed, and then the airflow diffuses outwards due to the centrifugal force at the moment of entering the machining ring 3, thereby reducing the adhesion of the flying grinding chips to the axle surface, and accelerating the airflow exchange inside the machining ring 3, and avoiding the internal seal of the machining ring 3 from heating up;
[0036] After use, since the interior of the machining ring 3 can be closed, abrasive can be injected into the machining ring 3 and then the machining ring 3 can be rotated, so that the grinding chips adhering to the inner wall of the machining ring 3 can be quickly ground off, thereby ensuring the cleanliness of the interior of the machining ring 3 and facilitating the collection and management of grinding chips.
