DETAILED DESCRIPTION

[0020] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0021] like Figure 2-5 As shown, a fan cover deburring device comprises a base 1, a rotating assembly 2, a pressing assembly 3 and a trimming assembly 4;

[0022] The rotating assembly 2 includes a rotating disk 21, the rotating disk 21 is rotatably connected to the base 1, and the bottom surface of the fan cover 5 is placed on the rotating disk 21;

[0023] The pressing assembly 3 includes a pressing base 31, a pressing cylinder 32 and a pressing block 33. The pressing cylinder 32 is arranged on the pressing base 31, and the telescopic axis of the pressing cylinder 32 faces the turntable 21. The pressing block 33 is arranged at the end of the telescopic axis of the pressing cylinder 32.

[0024] The trimming assembly 4 includes a cutter 41 , and a blade of the cutter 41 faces toward the burr 51 of the fan cover 5 .

[0025] In the fan cover burr removal equipment, the fan cover 5 whose burrs 51 need to be sheared is placed on the turntable 21, and the pressing cylinder 32 drives the pressing block 33 to press down on the fan cover 5 to limit the fan cover 5. Specifically, the pressing block 33 is rotatably connected to the end of the telescopic shaft of the pressing cylinder 32, so that when the fan cover 5 follows the rotation of the turntable 21, the pressing block 33 will not block the rotation of the fan cover 5; then the burrs 51 are used to cut across the cutter 41 in the process of following the movement of the fan cover 5, so that the burrs 51 are sheared. Compared with manual shearing, the efficiency can be improved, and the situation where a burr 51 is missed and not sheared can be avoided.

[0026] It is worth noting that the rotating assembly 2 includes a rotating motor 22, a motor bracket 23 and a push-up cylinder 24. The output shaft of the rotating motor 22 is fixedly connected to the turntable 21. The rotating motor 22 is arranged on the motor bracket 23. The motor bracket 23 is slidably connected to the base 1 in the vertical direction. The motor bracket 23 is fixedly connected to the telescopic shaft of the push-up cylinder 24 to drive the motor bracket 23 to move in the vertical direction. The rotating motor 22 can drive the turntable 21 to rotate, thereby driving the fan cover 5 arranged on the turntable 21 to rotate. The base 1 is provided with a first guide rail, and the motor bracket 23 is arranged on the first guide rail. Through the push-up cylinder 24, the motor bracket 23 can be lifted and lowered along the first guide rail in the vertical direction. By rising, the rotating motor 22 can be driven to rise through the motor bracket 23, thereby driving the fan cover 5 to rise. Combined with the downward pressure of the pressing assembly 3, the fan cover 5 can be limited and will not be separated from the turntable 21 during the rotation of the fan cover 5.

[0027] Optionally, a moving assembly 6 is further included, the moving assembly 6 includes a mounting frame 61 and a moving cylinder 62, the mounting frame 61 is slidably connected to the base 1, specifically, the base 1 is provided with a second guide rail, the mounting frame 61 is arranged on the second guide rail, the cylinder body of the moving cylinder 62 is arranged on the base 1, and the telescopic shaft of the moving cylinder 62 is fixedly connected to the mounting frame 61 to drive the mounting frame 61 to move in a direction close to or away from the turntable 21; the trimming assembly 4 is arranged on the mounting frame 61. By driving the mounting frame 61 to move in a direction away from the turntable 21 by the moving cylinder 62, the space around the turntable 21 can be increased, so that the fan cover 5 can be conveniently placed. After the fan cover 5 is placed, the mounting frame 61 is driven by the moving cylinder 62 to approach the turntable 21, so that the trimming assembly 4 can be close to the fan cover 5.

[0028] Specifically, the trimming assembly 4 also includes a crankshaft connecting rod 42, a trimming motor 43, a driving wheel 44 and a driven wheel 45. The output shaft of the trimming motor 43 is fixedly connected to the driving wheel 44, and the driving wheel 44 is transmission-connected to the driven wheel 45. One end of the crankshaft connecting rod 42 is connected to the driven wheel 45 and is arranged at a position deviating from the center of the driven wheel 45, and the other end of the crankshaft connecting rod 42 is fixedly connected to the cutter 41.

[0029] Preferably, the trimming assembly 4 also includes a knife seat 46, and the knife seat 46 is slidably connected to the mounting frame 61. Specifically, the mounting frame 61 is provided with a third guide rail in the front-to-back direction, and the knife seat 46 is installed on the third guide rail. One end of the knife seat 46 is connected to the crankshaft connecting rod 42, and the other end of the knife seat 46 is connected to the cutter 41, so that the cutter 41 extends into the fan cover 5 and the blade of the cutter 41 faces the inner side of the burr 51.

[0030] The trimming motor 43 drives the driving wheel 44 to rotate, and then drives the driven wheel 45 to rotate through the belt. Since the crankshaft connecting rod 42 is set at an eccentric position of the driven wheel 45, the driven wheel 45 can drive the knife holder 46 to move in the front-back direction relative to the mounting frame 61 through the crankshaft connecting rod 42 during the rotation of the driven wheel 45. It is only necessary to adjust the rotation speed of the trimming motor 43 to adjust the frequency of the front-back movement of the knife holder 46, thereby adjusting the frequency of the cutter 41 hitting the burr 51, so that the cutter 41 moves back and forth at a high height, and combined with the moving burr 51 passing over the blade of the cutter 41, the efficiency of cutting the burr 51 can be improved.

[0031] It is worth noting that it also includes a material stopper assembly 7, which includes a material stopper cylinder 71, a material stopper bracket 72 and a material stopper block 73. The cylinder body of the material stopper cylinder 71 is arranged on the mounting frame 61, and the telescopic shaft of the material stopper cylinder 71 is arranged downward, and the telescopic shaft of the material stopper cylinder 71 is connected to one end of the material stopper bracket 72, and the other end of the material stopper bracket 72 is provided with the material stopper block 73, so that the material stopper block 73 faces the lower side of the annular keel 52 of the fan cover 5. The telescopic shaft of the material stopper cylinder 71 can drive the material stopper bracket 72 to descend or rise in the vertical direction, thereby driving the material stopper block 73 to descend or rise in the vertical direction, and then realizing the movement of the material stopper block 73 away from or close to the lower side of the annular keel 52 of the fan cover 5. When it is necessary to cut the burr 51, the blocking block 73 can be raised to support the annular keel 52 from the lower side of the annular keel 52, and the cutter 41 is working on the upper side of the annular keel 52 at this time. In this way, the blocking block 73 can provide a force to prevent the annular keel 52 from moving downward, thereby preventing the fan cover 5 from tipping over due to uneven force.

[0032] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
