[0002] Polishing is a surface treatment technology that reduces the surface roughness of a workpiece through mechanical, chemical, or electrochemical actions to obtain a bright and flat surface. The process involves using polishing tools and abrasive particles or other polishing media to modify the surface of the workpiece. The main functions of polishing include improving the appearance quality, making the material surface smooth and flat, enhancing the aesthetics and texture; at the same time, polishing can also improve the optical performance, enhance the corrosion resistance, and in some cases improve the mechanical properties of the material. Polishing is widely used in many industries such as automobiles, jewelry, molds, optics, etc., and is an important means to improve the product quality and aesthetics.

[0003] During the production process of blades, it is necessary to polish the trailing edge sharp corners. The shapes of the blades are diverse, and the shapes of their trailing edge sharp corners will also vary. Existing polishing devices are difficult to polish according to the shape of the trailing edge sharp corners. Therefore, a precision polishing device for the trailing edge sharp corners of blades is proposed. Content of the Utility Model

A moving shaft 7 is fixedly installed on the first ejector cylinder body 501. A sliding support foot 8 is fixedly installed at one end of the first ejector cylinder body 501. A polishing mechanism 6 is arranged in the polishing chamber body 1. The clamping mechanism 5 can fix blades of different shapes in the positioning groove 4. After the blades of different shapes are fixed in the positioning groove 4, the polishing mechanism 6 is used to polish the trailing edge sharp corners of different shapes.

[0023] As Figure 3As shown, the clamping mechanism 5 includes a first ejector cylinder body 501 movably installed at the lower end of the positioning groove 4 and a second ejector cylinder body 502 fixed at the upper end of the positioning groove 4. A limiting ejector rod 507 is provided in both the first ejector cylinder body 501 and the second ejector cylinder body 502. A cylinder body pipeline 503 is connected to both the first ejector cylinder body 501 and the second ejector cylinder body 502. The end of the cylinder body pipeline 503 is connected to a piston cylinder body 504. A servo electric push rod 506 is provided on one side of the piston cylinder body 504. The clamping mechanism 5 further includes a linkage frame body 505 fixed at the end of the servo electric push rod 506, and the end of the linkage frame body 505 is fixed on the piston inside the piston cylinder body 504.

A lifting frame 10 is fixedly installed on the linkage frame body 505.

[0024] Specifically, the servo electric push rod 506 can drive the linkage frame body 505 to move forward. After the linkage frame body 505 moves forward, it will drive the piston inside the piston cylinder body 504 to move forward, thereby squeezing hydraulic oil into the first ejector cylinder body 501 and the second ejector cylinder body 502, causing the limiting ejector rods 507 in the first ejector cylinder body 501 and the second ejector cylinder body 502 to extend and fixing blades of different shapes in the positioning groove 4.

The polishing mechanism 6 further includes a recovery box body 607 provided at the bottom of the polishing chamber body 1. A limiting pin 606 is fixedly installed on the recovery box body 607.

[0026] Specifically, the horizontal servo slide 601 and the vertical servo slide 602 can drive the polishing wheel 605 at the output end of the polishing motor 604 to move back and forth and left and right. When the polishing wheel 605 moves back and forth and left and right, the stroke of the horizontal servo slide 601 and the vertical servo slide 602 can be controlled to make the polishing wheel 605 move along the trailing edge tip of blades of different shapes, so as to facilitate the user to polish the trailing edge tips of different shapes.

[0027] It should be noted that the present utility model is a precision polishing device for the trailing edge sharp corners of blades. During actual use, first place the blade in the positioning groove 4 and make the trailing edge sharp corner of the blade extend into the polishing chamber 1. Then, the servo electric push rod 506 can be started. After starting the servo electric push rod 506, it will drive the linkage frame 505 to move forward. After the linkage frame 505 moves forward, it will drive the piston in the piston cylinder body 504 to move forward, thereby squeezing the hydraulic oil into the first ejector cylinder body 501 and the second ejector cylinder body 502, causing the limit ejector rods 507 in the first ejector cylinder body 501 and the second ejector cylinder body 502 to extend, and fixing blades of different shapes in the positioning groove 4. After fixing blades of different shapes in the positioning groove 4, the horizontal servo slide 601 and the vertical servo slide 602 can be started. After starting the horizontal servo slide 601 and the vertical servo slide 602, they will drive the polishing wheel 605 at the output end of the polishing motor 604 to move back and forth, left and right. By controlling the stroke of the horizontal servo slide 601 and the vertical servo slide 602, the polishing wheel 605 can be moved along the trailing edge sharp corners of blades of different shapes, thus facilitating the user to polish the trailing edge sharp corners of different shapes. The metal debris generated during the polishing process will be collected by the recycling box 607. After the polishing is completed, the servo electric push rod 506 can be retracted. After retracting the servo electric push rod 506, the lifting frame 10 will lift one side of the first ejector cylinder body 501, making the first ejector cylinder body 501 tilt at a certain angle, allowing the workpiece on the first ejector cylinder body 501 to slide down automatically, realizing automatic workpiece blanking. During the blanking process, the telescopic side plate 9 will extend to prevent the workpiece from falling from both sides of the first ejector cylinder body 501. And the user can pull the recycling box 607 outwards. After pulling the recycling box 607 outwards, the limit pin 606 will disengage from the limit card slot 2, thus facilitating the user to remove the recycling box 607 for cleaning.
