DETAILED DESCRIPTION

[0020] The foregoing and other technical contents, features and effects of the utility model are described below in conjunction with the accompanying drawings. Figs. 1 to 4 The embodiment is described in detail.

[0021] The embodiment provides a surface treatment device for synchronous motor main shaft machining, as shown in the accompanying drawings. Figs. 1-4As shown, the system includes a first electric push rod 1 and an outer protective shell 2. The outer protective shell 2 is fixedly installed at the top of the movable rod of the first electric push rod 1. There are several first electric push rods 1, and the fixed ends of several first electric push rods 1 can be vertically fixedly installed below the motor spindle clamping platform. The overall height of the outer protective shell 2 can be adjusted by controlling the extension and retraction of the movable rod of the first electric push rod 1, thereby facilitating the coaxial setting of the outer protective shell 2 and the spindle clamping part. The synchronous motor spindle can be clamped by passing through the interior of the outer protective shell 2 and the ring frame 4. The height of the outer protective shell 2 can be finely adjusted by the first electric push rod 1 to make the motor spindle and the ring frame 4 coaxial, ensuring that the motor spindle is in the center of the ring frame 4. The top of the interior of the outer protective shell 2... A lateral adjustment mechanism 3 is provided, with its movable end connected to a ring frame 4. The lateral adjustment mechanism 3 drives the ring frame 4 to move laterally back and forth, synchronously causing the external device for clamping the motor spindle to rotate the motor spindle slowly and uniformly. This allows the various structures on the ring frame 4 to fully treat the outer surface of the motor spindle. The top of the ring frame 4 is equipped with a sandblasting mechanism 5 for sandblasting the motor spindle, and one side is equipped with a polishing mechanism 6 for grinding and polishing the motor spindle. The sandblasting mechanism 5 can sandblast the spindle surface from multiple angles, effectively eliminating dead angles and ensuring surface uniformity. The polishing mechanism 6 can adapt to the spindle diameter and maintain constant polishing pressure, thereby obtaining a stable and high-precision surface finish. The bottom of the ring frame 4 is equipped with a cleaning mechanism 7 for cleaning the motor spindle. The cleaning mechanism 7 combines high-pressure rinsing with mechanical brushing, effectively removing debris and impurities from the spindle surface caused by sandblasting and grinding, ensuring a clean and smooth surface. On the side of the ring frame 4 away from the polishing mechanism 6, a drying and inspection mechanism 8 is installed to dry and inspect the motor spindle. The drying and inspection mechanism 8 quickly dries residual droplets on the surface and performs online visual inspection of the spindle surface, ensuring cleanliness and dryness, providing a guarantee for the next processing step or factory inspection, and achieving seamless integration of processing and inspection. The end of the outer protective shell 2 is horizontally aligned with the sandblasting mechanism 5, polishing mechanism 6, cleaning mechanism 7, and drying and inspection mechanism 8. All corresponding parts are provided with slots for pipes to pass through. The air inlet pipe and sand inlet pipe of the sandblasting mechanism 5, the cable pipe of the polishing mechanism 6, the water inlet pipe of the cleaning mechanism 7, and the air inlet pipe of the air drying and inspection mechanism 8 are all passed through their corresponding slots to ensure that each mechanism can move normally within the outer protective shell 2 as the ring frame 4 moves laterally, ensuring the normal operation of each mechanism. A drain pipe 9 for discharging waste liquid is fixedly connected to the middle of the bottom end of the outer protective shell 2. The outer protective shell 2 can protect the entire processing mechanism and effectively prevent dust diffusion and liquid splashing. The drain pipe 9 can be connected to an external waste liquid collection container through a pipe. The waste liquid mixed with debris particles generated when cleaning the motor spindle can be discharged from the drain pipe 9 for centralized collection and treatment.

[0022] In one optional embodiment, the lateral adjustment mechanism 3 includes a geared motor 301, a lead screw 302, and a guide rod 303. The lead screw 302 is connected to the output end of the geared motor 301 via a spline and is horizontally rotatably connected to one side of the top of the outer protective shell 2 via a bearing. The guide rod 303 is horizontally fixedly connected to the inner top of the outer protective shell 2 on the side away from the lead screw 302. The top of the ring frame 4 is connected to the outside of the lead screw 302 via a threaded drive on the side corresponding to the lead screw 302. The side of the ring frame 4 corresponding to the guide rod 303 is sleeved on the outside of the guide rod 303 and can slide laterally along its outside. The geared motor 301 drives the lead screw 302 to rotate forward or reverse, which can drive the ring frame 4 to move horizontally back and forth along the direction of the guide rod 303, thereby moving the overall structure on the ring frame 4 along the axial direction of the motor spindle, which facilitates the surface treatment of the entire motor spindle.

[0023] In one optional embodiment, the sandblasting mechanism 5 includes a plurality of sandblasting gun heads 501, which are evenly divided into two groups. One group of sandblasting gun heads 501 is vertically and equidistantly inserted into the top of the annular frame 4, and the other group of sandblasting gun heads 501 is obliquely and equidistantly inserted into the top of the annular frame 4. The outlet ends of both groups of sandblasting gun heads 501 are inserted into the interior of the annular frame 4 and face the center of the annular frame 4, which ensures that the sandblasting gun heads 501 are always aligned with the surfaces of motor spindles of different diameters and sandblast them. The sand inlet and air inlet ends of the top of the two groups of sandblasting gun heads 501 are connected to an external sand storage tank and a high-pressure air source, respectively. The arrangement of the two groups of sandblasting gun heads 501 can sandblast the surface of the spindle from multiple angles, effectively eliminating dead angles and ensuring the uniformity of the surface.

[0024] In one optional embodiment, the polishing mechanism 6 includes a second electric push rod 601, a support frame 602, a grinding wheel 603, and a drive motor 604. The fixed end of the second electric push rod 601 is horizontally fixedly mounted on the outer ring surface of the annular frame 4. The support frame 602 is fixedly mounted on the movable end of the second electric push rod 601, and the grinding wheel 603 is rotatably connected inside the support frame 602. Both the support frame 602 and the grinding wheel 603 are disposed inside the annular frame 4. The drive motor 604 is fixedly mounted on the side of the support frame 602, and its output end is connected to the side of the annular frame 4. The spline connects to the grinding wheel 603; the second electric push rod 601 can adjust the distance between the grinding wheel 603 and the surface of the motor spindle, so as to facilitate the adjustment of the position of the grinding wheel 603 according to the diameter of the motor spindle, making it easy to adapt to motor spindles of different diameters. The drive motor 604 drives the grinding wheel 603 to rotate at high speed, while the motor spindle itself rotates slowly. The lateral adjustment mechanism 3 drives the ring frame 4 to move laterally as a whole, so that the grinding wheel 603 can fully grind all parts of the outer surface of the motor spindle, improving the smoothness of the motor spindle surface.

[0025] In one optional embodiment, the cleaning mechanism 7 includes a high-pressure nozzle 701, a spring rod 702, and a brush 703. The high-pressure nozzle 701 is fixedly installed on the inner bottom wall of the annular frame 4. There are several high-pressure nozzles 701, all of which are fixedly installed on the inner bottom wall of the annular frame 4. The water outlets of the several high-pressure nozzles 701 all face vertically upwards, and the water inlets of the several high-pressure nozzles 701 are interconnected and connected to an external high-pressure water supply pipe. High-pressure water is injected into the high-pressure nozzles 701 through the external high-pressure water supply pipe, which can rinse the spindle surface after sandblasting and grinding, facilitating the removal of debris particles adhering to the spindle surface and maintaining the spindle surface's cleanliness. Clean and smooth; the fixed end of the elastic rod 702 is fixedly connected to the inner bottom wall of the ring frame 4, and the brush 703 is fixedly connected to the movable end of the elastic rod 702 and faces the center of the ring frame 4; the elastic rod 702 consists of a sleeve rod, a spring and a movable rod. The movable rod passes through the sleeve rod through the spring. The bottom end of the sleeve rod is fixedly connected to the inner bottom wall of the ring frame 4, while the brush 703 is fixedly connected to the top end of the movable rod. The movable rod can move up and down inside the sleeve rod under the action of the spring, so that the brush can press against the surface of the main shaft with different diameters. It works in conjunction with the high-pressure nozzle 701. When the motor main shaft rotates, the brush can thoroughly clean the surface of the main shaft, further improving the cleaning effect on the motor main shaft.

[0026] In one optional embodiment, the air-drying inspection mechanism 8 includes a high-pressure air knife 801 and an industrial camera 802. The high-pressure air knife 801 is fixedly installed horizontally on the side of the ring frame 4 away from the polishing mechanism 6, with its outlet end facing the center of the ring frame 4. The air inlet end of the high-pressure air knife 801 can be connected to an external ventilation duct. The high-pressure air knife 801 can quickly dry the liquid remaining on the surface of the motor spindle, ensuring the spindle is dry. The industrial camera 802 is fixedly installed on the side of the ring frame 4 away from the polishing mechanism 6 and positioned above the high-pressure air knife 801. The industrial camera 802 can perform visual inspection on the surface of the motor spindle to ensure that the surface treatment effect of the motor spindle meets the set standard, thereby improving the processing and inspection efficiency of the motor spindle.

[0027] The first electric push rod 1, the geared motor 301, the second electric push rod 601, the drive motor 604, and the industrial camera 802 are all electrically connected to the external control unit and are all electrically connected to the external circuit through wires.

[0028] In summary, the surface treatment device for machining synchronous motor spindles has the following operating steps:

[0029] 1. The operator inserts the synchronous motor spindle to be processed into the outer protective shell 2 and the ring frame 4, which have been raised to a high position. The two ends of the spindle are firmly clamped to the external spindle rotation drive device. By controlling several first electric push rods 1, the height of the outer protective shell 2 is finely adjusted so that the center of the ring frame 4 is coaxial with the axis of the motor spindle.

[0030] 2. Control the motor spindle to rotate at a constant speed and start the sandblasting mechanism 5. The external high-pressure air source and sand storage tank start working. The abrasive is sprayed onto the spindle surface from multiple angles through two sets of sandblasting gun heads 501. At the same time, the external drive equipment drives the spindle to rotate slowly and at a constant speed. The reduction motor 301 drives the lead screw 302 to rotate, which drives the entire ring frame 4 to move smoothly along the spindle axis at a set speed along the guide rod 303, forming a sandblasting treatment trajectory that fully covers the outer surface of the spindle and has no dead spiral lines.

[0031] 3. After the sandblasting process is completed, the ring frame 4 moves back to the starting end, and the sandblasting mechanism 5 is closed; the second electric push rod 601 pushes the support frame 602 and the grinding wheel 603 to feed radially until the grinding wheel 603 is in contact with the spindle surface. Then the drive motor 604 starts and drives the grinding wheel 603 to rotate at high speed; the spindle continues to rotate, and at the same time the transverse adjustment mechanism 3 drives the ring frame 4 to move axially again. The high-speed rotating grinding wheel 603 performs comprehensive grinding and polishing on the spindle surface.

[0032] 4. After polishing, the ring frame 4 returns to the starting end, the polishing mechanism 6 retracts and closes; water is supplied to the high-pressure nozzle 701 through the external high-pressure water supply system to powerfully rinse the spindle surface; at the same time, under the constant force of the elastic rod 702, the brush 703 always adheres to the spindle surface, and under the rotation of the spindle, the brush 703 mechanically scrubs it, working in conjunction with the high-pressure water flow to thoroughly remove abrasive residues and metal shavings from the surface; the waste liquid generated by rinsing flows into the external collection and treatment system through the drain pipe 9 at the bottom of the outer protective shell 2.

[0033] 5. After cleaning, the air drying inspection mechanism 8 is activated, and the high-pressure air knife 801 blows out a high-speed airflow to quickly disperse and evaporate the residual water stains on the spindle surface, making it completely dry; at the same time, the industrial camera 802 takes real-time pictures of the dried spindle surface and transmits the image data to the control system for online visual inspection, automatically judging the surface treatment quality, thereby completing the processing of the motor spindle.

[0034] The above description is only for illustrating the present utility model. It should be understood that the present utility model is not limited to the above embodiments, and various modifications that conform to the concept of the present utility model are within the protection scope of the present utility model.
