[0002] Thermal spraying is a workpiece surface treatment process that uses high-pressure air to blow the molten coating material onto the surface of the workpiece, causing the coating material to adhere to the surface of the workpiece to form a protective layer, making the workpiece's anti-oxidation and corrosion resistance properties better.

[0003] When thermal spraying is performed on a tubular workpiece, after the clamping member of the tubular workpiece fixes the tubular workpiece, the thermal spraying gun is generally located on the outside or inside of the workpiece, and thermal spraying is performed on the outer wall or inner wall of the tubular workpiece.

A clamping component 7 is fixedly installed on the rear side of the top of the L-shaped bracket 23.

[0028] See also Figure 2-4The rotating component 1 includes a mounting seat 11, and a fixed shaft 12 is fixedly mounted on the mounting seat 11. A fixed plate 13 is fixedly mounted on the left end of the fixed shaft 12. Two annular baffles 14 are fixedly mounted on the right end of the fixed shaft 12. A sleeve 15 is sleeved on the outer side of the right annular baffle 14, and the sleeve 15 can rotate on the outer side of the annular baffle 14. An annular flange is arranged at the right opening of the sleeve 15, and the annular flange is arranged between the two annular baffles 14. The sleeve 15 is stably sleeved on the outer side of the annular baffle 14. Ball bearings 16 are arranged in an array between the sleeve 15 and the annular baffle 14. Through the arrangement of the ball bearings 16, the sleeve 15 can rotate more smoothly on the outer side of the annular baffle 14. A ring gear 17 is fixedly mounted on the right end of the sleeve 15, and a gear 18 is meshed on the surface of the ring gear 17. A driving motor is arranged at the center of the gear 18, thereby driving the gear 18 and the ring gear 17 to rotate. The center of the gear 18 is rotatably connected with a shaft seat 19, which is fixedly mounted on the front side of the mounting seat 11, the L-shaped bracket 12 is fixedly mounted on the center of the fixing plate 13, and the L-shaped bracket 23 is fixedly mounted on the center of the sleeve 15. Thus, the L-shaped bracket 23 can rotate relative to the L-shaped bracket 12 and with the fixing shaft 12 as the axis.

[0029] See also Figure 1-3 The limiting component 4 includes two side plates 41 fixedly mounted on the top of the fixed plate 13 and distributed front and back, a rotating plate 42 is rotatably connected between the two side plates 41, a clamping block 43 is integrally formed at the bottom of the right end of the rotating plate 42, a cylinder 44 is fixedly mounted between the bottom of the left end of the rotating plate 42 and the L-shaped bracket 2, and a clamping tooth 45 is arranged in an array on the left outer wall of the sleeve 15, and the clamping block 43 is inserted between two adjacent clamping teeth 45. The width of the clamping block 43 is equal to the spacing between two adjacent clamping teeth 45. The clamping block 43 is clamped between two adjacent clamping teeth 45 to inhibit the sleeve 15 from rotating, so that the sleeve 15 after rotation is fixed at the current position.

[0030] See also Figure 1 and Figure 5The spraying component 5 includes an L-shaped slide plate 51 which is arranged on the top of the L-shaped bracket 2. The L-shaped slide plate 51 is located on the axis of the three-jaw chuck 6. A mounting groove 52 is arranged on the upper part of the vertical part of the L-shaped bracket 2. The mounting groove 52 is in an inverted T shape. The L-shaped slide plate 51 is inserted into the mounting groove 52. The cross section of the horizontal part of the L-shaped slide plate 51 is in an inverted T shape except for the two ends, which is adapted to the mounting groove 52. A spring 53 is fixedly installed between the left end of the L-shaped slide plate 51 and the L-shaped bracket 2. The elasticity of the spring 53 makes the L-shaped slide plate 51 have a tendency to move to the left. A nozzle 54 is fixedly installed on the right end of the L-shaped slide plate 51. The shell of the nozzle 54 is welded to the end of the L-shaped slide plate 51. During welding, the nozzle 54 can be adjusted to tilt toward the rear lower side. The left side of the vertical part of the L-shaped bracket 2 is rotatably connected with a roller 55 and a winding wheel 56. A servo motor is provided at the center of the winding wheel 56 to drive the winding wheel 56 to rotate clockwise or counterclockwise. The winding wheel 56 is located directly below the roller 55. A steel wire rope 57 is fixedly installed at the left end of the L-shaped slide 51. The steel wire rope 57 abuts against the upper right side of the roller 55, and the other end of the steel wire rope 57 is fixedly installed on the surface of the winding wheel 56. The steel wire rope 57 is horizontal between the L-shaped slide 51 and the roller 55. Therefore, when the winding wheel 56 rotates to wind up the steel wire rope 57, the pulling force of the steel wire rope 57 on the end of the L-shaped slide 51 is horizontal to the right.

[0031] See also Figure 1 and Figure 6 The clamping component 7 includes a support plate 71 fixedly mounted on the top of the rear side of the L-shaped bracket 23. The support plate 71 is provided with an inclined branch at the lower side near the right end thereof, and the support plate 71 is further supported by the branch, so that the support plate 71 is fixedly mounted on the rear side of the L-shaped bracket 23 more stably. A C-shaped plate 72 is fixedly mounted on the left end of the support plate 71. The top and bottom of the C-shaped plate 72 are provided with threaded holes. A screw 73 is threadedly connected to the threaded hole provided in the C-shaped plate 72. The end of the screw 73 is rotatably connected to an arc-shaped clamping plate 74. The arc centers of the C-shaped plate 72 and the arc-shaped clamping plate 74 coincide with the axis center of the three-jaw chuck 6. A ball bearing 2 75 is arranged in an array on one side of the arc-shaped clamping plate 74 near the arc center. A hemispherical groove is arranged in an array along the length direction of the arc-shaped clamping plate 74 near the arc center, and the ball bearing 2 75 is arranged in the hemispherical groove. Therefore, when the arc clamping plate 74 is clamped on the end of the tubular workpiece, the second ball 75 abuts against the surface of the tubular workpiece, making it convenient for the tubular workpiece to rotate.

[0032] When in use, the three teeth of the three-jaw chuck 6 are clamped on the right end of the tubular workpiece, and then the C-shaped plate 72 is sleeved on the left end of the tubular workpiece, and then the screw 73 is turned to clamp the two arc-shaped clamping plates 74 on the upper and lower sides of the tubular workpiece, thereby fixing the two ends of the tubular workpiece, and then the three-jaw chuck 6 is driven to rotate by the rotating shaft of the three-jaw chuck 6, thereby driving the tubular workpiece to rotate synchronously, and the right end of the tubular workpiece slides on the surface of ball bearing 2 75.

[0033] The winding wheel 56 is then rotated to wind up the wire rope 57, which moves across the surface of the roller 55 and pulls the L-shaped slide 51 to move to the right. The spring 53 is compressed, and the nozzle 54 follows the L-shaped slide 51 to move to the right, is inserted from the left end of the tubular workpiece, and moves to the right along the axis of the tubular workpiece, thereby performing thermal spraying on the inner wall of the tubular workpiece.

[0034] After that, the winding wheel 56 rotates in the opposite direction to release the wire rope 57, and the elasticity of the spring 53 causes the L-shaped slide plate 51 to gradually move to the left, and the nozzle 54 moves out from the end of the tubular workpiece. Then, the gear 18 rotates, driving the ring gear 17 to rotate, thereby driving the sleeve 15 to rotate along the ring gear 17, driving the L-shaped bracket 23 to deflect to the rear side, and the tubular workpiece follows the L-shaped bracket 23 to deflect to the rear side along the fixed axis 12 synchronously until the tubular workpiece is located at the rear lower side of the nozzle 54. Then, the output shaft of the cylinder 44 extends, driving the rotating plate 42 to deflect, driving the clamping block 43 to insert into the two adjacent clamping teeth 45, limiting the sleeve 15 and inhibiting the sleeve 15 from rotating.

[0035] Similarly, the three-jaw chuck 6 drives the tubular workpiece to rotate, the winding wheel 56 rotates, the wire rope 57 is wound, and the spray head 54 follows the L-shaped slide plate 51 to move horizontally to the right, so as to spray the outer wall of the tubular workpiece.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
