[0018] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0019] A drilling device for processing a compressor housing includes a base 1 and a drilling mechanism 2 disposed above the base 1. The top of the base 1 is also provided with a positioning mechanism 3 and a locking mechanism 4. The positioning mechanism 3 includes a vertical plate I32 driven by a motor I31. The vertical plate I32 is fixed with a rotating shaft 34 by a bearing 33. The rotating shaft 34 is connected to a positioning plate 36 by a U-shaped frame I35. A cylindrical cylinder 37 with a sealed end is provided on one side of the positioning plate 36. A motor I138 connected to the cylindrical cylinder 37 is provided on the positioning plate 36. A strip-shaped opening 39 is axially provided on the top wall of the cylindrical cylinder 37, and a circular groove 5 is provided on one end face of the positioning plate 36 to accommodate the sealed end side wall of the cylindrical cylinder 37.

[0020] The locking mechanism 4 includes a vertical plate II41 driven by a hydraulic rod 42. A U-shaped frame II44 driven by a motor III43 is provided on one side of the vertical plate II41. A locking plate 45 is provided on the U-shaped frame II44. A circular groove 46 for accommodating the open end of the cylinder 37 is provided at one end of the locking plate 45. A mounting pipe 47 for mounting a fan 48 is also provided on the locking plate 45. A dust collection bag 49 is sleeved on the mounting pipe 47.

[0021] like Figure 2 , 3As shown, the bottom wall inside the opening of the cylinder 37 is inclined, and the top of the bottom wall inside the opening of the cylinder 37 is on the same side as the sealed end of the cylinder 37. An electromagnetic adsorption strip 6 is also provided on the bottom wall inside the opening of the cylinder 37. When the adsorption strip 6 is energized, it can magnetically attract large metal debris that falls into the cylinder 37, preventing it from scattering everywhere. During subsequent cleaning, when the opening of the cylinder 37 is opened, the adsorption strip 6 is de-energized, and the impurities separate from it. At this time, the impurities can flow along the inclined surface of the bottom wall inside the cylinder 37 to its opening and fall into the container placed directly below the cylinder 37, thus facilitating the cleaning of impurities. Of course, the impurities can also be cleaned by manually intervening by inserting tools into the inside of the cylinder 37.

[0022] like Figure 2 As shown, the top of the base 1 is provided with a horizontal groove 7 to accommodate the bottom of the vertical plate II41, and a sliding rod 8 is provided in the groove 7, which passes through the sliding hole on the bottom side wall of the vertical plate II41.

[0023] like Figure 2 As shown, a circular seat 9 is provided at the bottom of the vertical plate I32, and a circular groove for accommodating the circular seat 9 is provided at the top of the base 1. The output shaft of the motor I31 is fixedly connected to the middle of the bottom of the circular seat 9.

[0024] like Figure 1 , 2 As shown in Figure 3, the positioning plate 36 is provided with an L-shaped frame I10 for fixing the motor II 38. The output shaft of the motor II 38 is fixedly connected to the center of the sealed end of the cylinder 37. A pointer 11 is vertically arranged on the output shaft of the motor II 38 between the positioning plate 36 and the L-shaped frame I10.

[0025] The drilling mechanism 2 includes an L-shaped frame II21 mounted above the base 1. A lead screw 22 driven by a drive motor 23 is mounted on the horizontal end of the L-shaped frame II21. Bosses 24 are mounted on the L-shaped frame II21 to fix both ends of the lead screw 22. A slide block 25 is mounted on the lead screw 22, and a screw hole is provided on the slide block 25 for screwing into the lead screw 22. A positioning rod 26 passing through a through hole in the slide block 25 is also provided between the two sets of bosses 24. An electric push rod 27 is vertically mounted on the slide block 25. A drilling motor 28 is mounted at the bottom of the electric push rod 27. A drill bit 29 is mounted on the output shaft of the drilling motor 28, and the drill bit 29 is located directly above the strip-shaped opening 39.

[0026] The working principle of this invention is as follows: In the initial state of this device, the hydraulic rod 42 drives the vertical plate II 41 to move to the left, which causes the vertical plate II 41 to drive the motor III 43, the mortise frame II 44 and the locking plate 45 to move to the left, so that the locking mechanism 4 moves away from the positioning mechanism 3. At the same time, the motor I 31 drives the circular seat 9 and drives the vertical plate I 32 to rotate 90 degrees, so that the vertical plate I 32 drives the mortise frame I 35, the positioning plate 36, the motor II 38 and the cylinder 37 to rotate in the same direction and angle through the rotating shaft 34. Finally, the cylinder 37 is set to face forward or backward, so that people can put the compressor housing on the cylinder 37 and one end contacts the positioning plate 36. At this time, since the cylinder 37 is set longitudinally, the locking mechanism 4 will not affect the normal loading and unloading of the housing on the cylinder 37.

[0027] During use, motor I31 drives the positioning mechanism 3 to rotate and reset, so that the cylinder 37 is positioned laterally and located between the positioning plate 36 and the locking plate 45, specifically as follows: Figure 1 , 2 As shown in Figure 3, at this time, the hydraulic rod 42 drives the vertical plate II 41 to drive the motor III 43, the shaped frame II 44 and the locking plate 45 to move to the right, so that the circular groove 46 is fastened to the left end of the cylinder 37 and the locking plate 45 abuts against the left end of the housing, thereby realizing the locking and fixing of the housing by the locking plate 45 and the positioning plate 36.

[0028] At this time, the cylinder 37 is driven to rotate inside the housing by the motor II38. The circular groove 46 and the slot 5 can support the cylinder 37. When the output shaft of the motor II38 rotates, it can drive the pointer 11 to rotate. When the pointer 11 is in a vertical downward position, it indicates that the strip opening 39 on the cylinder 37 is above it and directly opposite the position of the drilled hole on the housing, so as to facilitate the position adjustment of the strip opening 39. When drilling, the drive motor 23 drives the lead screw 22 to rotate in the screw hole on the slide 25, so as to move the slide 25 and drive the electric push rod 27 at the same time. The drilling motor 28 and drill bit 29 move laterally, and the electric push rod 27 drives the drilling motor 28 and drill bit 29 to move downward, so that the drilling motor 28 can drill holes in different areas of the top of the shell laterally through the drill bit 29. When the drill bit drills through the side wall of the shell, it will pass through the strip opening 39 and slide into the cylinder 37. At this time, the debris obtained from drilling falls to the outside of the shell and can be extracted by other dust removal equipment, or it can slide off the outer wall of the shell and fall into the container above the base 1 for recycling. Since the above structure and equipment are all existing technologies, they will not be described in detail.

[0029] When debris falls into the cylinder 37, the fan 48 operates to guide the dust and debris into the dust collector bag 49 through the installation pipe 47 for filtration, thus achieving dust collection. Larger and heavier debris falls to the bottom of the cylinder 37, where the electrically powered adsorption strip 6 magnetically attracts the debris, preventing it from scattering and causing it to fall quickly to the ground when the cylinder 6 opens. When drilling is required in different areas of the outer wall of the housing, the motor III 43 drives the frame II 44 to rotate the locking plate 45. At this time, the locking plate 45 rotates the housing, cylinder 37, and positioning plate. The 36 and the I35 rotate together, and the I35 drives the rotating shaft 34 to rotate on the bearing 33, causing the housing, which is locked and fixed by the locking plate 45 and the positioning plate 36, to rotate. This causes the position of the housing to be drilled to rotate to the top, so that the drill bit 29 can drill at the top position. Before this, the cylinder 37 needs to be rotated by the motor II38 to drive the strip opening 39 to adjust its position. At the same time, the pointer 11 can easily rotate the strip opening 39 to the top of the cylinder 37 to face the drilling area, so that the side wall of the housing can be drilled through, or the drilling debris can fall into the cylinder 37.

[0030] After drilling is completed, the locking mechanism 4 moves to the left to reset, and at the same time, the positioning mechanism 3 rotates to drive the cylinder 37 and the shell to rotate 90 degrees, so that people can easily pull out the shell on the cylinder 37 and replace it. The present invention supports and fixes the entire side wall of the shell through the cylinder 37, preventing the side wall from being suspended and improving the safety during drilling. The debris obtained from drilling falls into the cylinder 37 through the strip opening 39, so as to effectively prevent the debris from adhering to the inner wall of the shell. At the same time, the dust is drawn out by the fan 48 and filtered and collected by the dust collection bag 49. Large-volume impurities are magnetically attracted to the adsorption strip 6 so that they can be cleaned after the opening of the cylinder 37 is opened.

[0031] The present invention has been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
