[0033] Referring to Figure 1, the base 1 includes a support plate 11 and support legs 12. The support plate 11 is a square plate made of metal. There are two support legs 12 arranged horizontally and at intervals. The lengths of the two support legs 12 are parallel to each other. The support legs 12 are fixedly connected to the lower plate surface of the support plate 11. The base 1 provides stable support for the fixing component 2, the sliding component 3, and the grinding component 4, preventing the grinding component 4 from shaking during the grinding process.

[0034] Referring to Figure 2 , the fixing component 2 includes a fixing base 21, a chuck body 22, and movable jaws 24. The fixing base 21 is a right triangular prism. The fixing base 21 is fixedly connected to one side of the upper plate surface of the support plate 11. The side wall of the fixing base 21 away from the edge of the plate surface of the support plate 11 is perpendicular to the plate surface of the support plate 11. The right triangular prism-shaped fixing base 21 has higher stability. The chuck body 22 is fixedly connected to the side wall of the fixing base 21 perpendicular to the plate surface of the support plate 11. The chuck body 22 is arranged at an interval from the support plate 11.

[0035] Referring to Figure 2 , three placement grooves 23 are formed on the table surface of the chuck body 22 facing away from the fixing base 21. The placement grooves 23 are evenly distributed on the table surface of the chuck body 22 and are arranged centripetally in the length direction. There are three movable jaws 24. The three movable jaws 24 are respectively slidably installed in the three placement grooves 23. The center of the equilateral triangle formed by the three movable jaws 24 at rest coincides with the center of the table surface of the chuck body 22. The three movable jaws 24 can approach or move away from the center of the table surface of the chuck body 22 simultaneously. The inclined surfaces of the movable jaws 24 facing away from the center of the table surface of the chuck body 22 are processed into a three-stage stepped shape. The fixing component 2 can stably fix lean tube connectors of different shapes and sizes, facilitating subsequent grinding of the lean tube connectors.

[0036] Combined with Figure 1 and Figure 3 , a semi-circular sliding groove 31 is formed on the upper plate surface of the support plate 11. The arc opening of the sliding groove 31 faces the fixing base 21. The inner walls at both ends of the sliding groove 31 are flush with the side wall of the fixing base 21 perpendicular to the support plate 11. Teeth are processed on the inner wall of the sliding groove 31 close to the fixing base 21. The sliding component 3 includes a sliding seat 32 and a limiting member 33. The sliding seat 32 is a square column and is slidably arranged on the plate surface of the support plate 11. A protruding sliding block 321 is fixedly connected to the lower end of the sliding seat 32. The protruding sliding block 321 is slidably arranged in the sliding groove 31.

One end of the spring is fixedly connected to the blind hole, and the other end of the spring is fixedly connected to one end of the limiting member 33. The other end of the limiting member 33 is processed into a toothed end 331. The toothed end 331 is a single tooth, and the toothed end 331 meshes with the teeth on the inner wall of the sliding groove 31. By pushing the sliding seat 32, the protruding slider 321 moves in the sliding groove 31, and the toothed end 331 can be fixed in the tooth groove on the inner wall of the sliding groove 31. Fixing the sliding seat 32 can improve the stability of the grinding assembly 4 during the grinding process.

[0038] Combined with Figure 1 and Figure 3 , the sliding assembly 3 further includes a baffle 34 and a sliding guide rail 35. The baffle 34 is a strip-shaped metal plate and is semi-circular.

The surface of the baffle 34 is flush with the inner wall of the sliding groove 31. The baffle 34 can prevent the waste generated during the grinding of the lean tube connector by the grinding device from splashing into the sliding groove 31, interfering with the sliding of the sliding seat 32, and reducing the grinding accuracy.

[0039] Combined with Figure 1 and Figure 3 , the sliding guide rail 35 is a square column. The bottom surface of the sliding guide rail 35 is fixedly connected to the upper end of the sliding seat 32. The sliding guide rail 35 and the sliding seat 32 are arranged in a T shape. A trapezoidal groove 351 is formed on the top surface of the sliding guide rail 35 facing away from the sliding seat 32. The length direction of the trapezoidal groove 351 is parallel to the length direction of the sliding guide rail 35, and the extension line of the length direction of the trapezoidal groove 351 always coincides with the center of the sliding groove 31. The opening area of the trapezoidal groove 351 is smaller than the bottom area. The grinding assembly 4 is slidably arranged on the sliding guide rail 35. The sliding assembly 3 can enable the grinding assembly 4 to grind the lean tube connector to be ground from multiple angles, which can improve the working efficiency compared with manually adjusting the connector.

[0040] Combined with Figure 3 and Figure 4, the grinding assembly 4 includes a placement seat 41, an electric push rod 42, a motor 43, and a spherical grinding wheel 44. The placement seat 41 is square-shaped, and a trapezoidal sliding block (not shown in the figure) is fixedly connected to the lower end face of the placement seat 41. The trapezoidal sliding block is adapted to the trapezoidal groove 351 and is slidably installed in the trapezoidal groove 351. The electric push rod 42 is fixedly installed at one end of the upper surface of the sliding guide 35 away from the fixed seat 21. The length direction of the electric push rod 42 is parallel to the length direction of the sliding guide 35. The push rod of the electric push rod 42 is fixedly connected to the side wall of the placement seat 41 facing away from the fixed seat 21, and the length of the push rod is less than the length of the sliding guide 35. The motor 43 is fixedly connected to the upper surface of the placement seat 41. The spherical grinding wheel 44 is composed of a grinding ball 441 and a connecting shaft 442. The grinding ball 441 is fixedly connected to one end of the connecting shaft 442, and the end of the connecting shaft 442 away from the grinding ball 441 is detachably connected to the output shaft 431 of the motor 43. The electric push rod 42 pushes the placement seat 41 close to the movable claw 24, and the motor 43 rotates to drive the spherical grinding wheel 44 to perform grinding work. The grinding assembly 4 can grind and polish the lean tube connector to be ground, improving the work efficiency and the qualified product rate at the same time.

[0041] Combined with Figure 3 and Figure 4 , a fixing plane 443 is formed by cutting along the length direction on the peripheral wall of the connecting shaft 442 away from the grinding ball 441. A groove adapted to the connecting shaft 442 is opened on the end face of the output shaft 431. The end of the connecting shaft 442 processed with the fixing plane 443 is detachably inserted into the groove on the end face of the output shaft 431.

[0042] Referring to Figure 4 , first limiting notches 4311 and second limiting notches 4421 are respectively opened on the peripheral walls of the output shaft 431 and the connecting shaft 442 away from the fixing plane 443. The first limiting notch 4311 communicates with the outer peripheral wall of the output shaft 431 and the groove opened on the end face of the output shaft 431. When the connecting shaft 442 is inserted into the groove on the end face of the output shaft 431, the side walls on the same side of the first limiting notch 4311 and the second limiting notch 4421 are flush. A first limiting groove 4312 is opened on the peripheral wall of the output shaft 431 opposite to the first limiting notch 4311. The length direction of the first limiting groove 4312 is perpendicular to the length direction of the output shaft 431. The side walls on the same side of the first limiting notch 4311 and the second limiting notch 4421 are flush with the first limiting groove 4312, and the first limiting notch 4311 and the second limiting notch 4421 are spaced apart from the first limiting groove 4312.

[0043] Combined with Figure 3 and Figure 4, the grinding assembly 4 further includes a fixing buckle 45, which is a U-shaped elastic member. When the connecting shaft 442 is inserted into the groove on the end face of the output shaft 431, one leg of the fixing buckle 45 is clamped in the first limiting notch 4311 and the second limiting notch 4421, and the other leg of the fixing buckle 45 is clamped in the first limiting groove 4312. Triangular thickening parts are formed on the opposite side walls of the two ends of the fixing buckle 45. The thickening parts can make the two ends of the fixing buckle 45 clamped on the outer wall of the output shaft 431, avoiding the loosening of the buckle caused by the rotation of the motor 43 during the grinding process. The fixing buckle 45 clamps and fixes the connecting shaft 442 on the output shaft 431, facilitating the maintenance and replacement of the spherical grinding wheel 44.
