[0009] Preferably, the mounting block is fixed to the bottom center of the mounting cylinder, and the limiting block is connected to the inside of the limiting groove to limit the knob so that the knob can only rotate.

[0010] Preferably, the outer wall of the knob is provided with anti-slip texture to prevent slippage, and the deflection plate is fixed to the middle of the outer wall of the rotating shaft.

[0011] Preferably, the baffle slides inside the mounting cylinder to limit the screw and prevent it from dislodging from the mounting cylinder, and the screw passes through the top center of the mounting cylinder.

[0012] Preferably, the fixing mechanism includes a housing fixed to the top of the deflection plate, slide rods symmetrically fixed to the top between the two sides of the inner cavity of the housing, slide plates symmetrically fixed to the outer side walls of the slide rods, a connecting plate fixed to the bottom center between the opposite sides of the two slide plates, a connecting shaft fixed to the bottom edge of the connecting plate, a vertical plate fixed to the top center of the slide plates, clamps fixed to the opposite sides of the two vertical plates, a drive motor fixed to the bottom center of the inner cavity of the housing, a turntable fixed to the end of the output shaft of the drive motor, and vortex grooves symmetrically formed at the top center of the turntable.

A movable slot is provided in the middle of the top of the outer shell, and the vertical plate is located inside the movable slot.

[0014] This utility model provides a device for machining oblique oil holes on the rear cover of an automotive air conditioning compressor, which has the following beneficial effects:

[0015] 1. This application, through the setting of the adjustment mechanism, by rotating the knob, which is screwed to the screw rod, the screw rod moves when the knob is rotated, thereby driving the connecting block to move, changing the length of the screw rod exposed on the outside of the mounting cylinder, thereby causing the deflection plate to drive the rotating shaft to deflect and change the angle. This facilitates changing the angle during the processing of the back cover, making it easy to adjust the angle according to the angled oil hole being processed, simplifying the processing, adapting to different back cover processing, improving versatility, reducing processing complexity, and increasing production efficiency.

[0016] 2. This application, through the setting of a fixing mechanism, places the back cover between two clamps. By starting the drive motor, the turntable rotates, causing the vortex groove to rotate, thereby causing the connecting shaft to move inside the vortex groove. This brings the connecting shaft closer to the center of the turntable, causing the connecting plate to move closer to each other, and the vertical plate to move the clamps closer to each other, thus clamping and fixing the back cover, thereby ensuring stability during processing, preventing the back cover from shaking, and ensuring processing quality.

[0032] Please refer to it again. Figure 5 and Figure 6The fixing mechanism 5 includes a housing 501 fixed to the top of the deflection plate 3. Slide rods 502 are symmetrically fixed to the top between the two sides of the inner cavity of the housing 501. Slide plates 503 are symmetrically fixed to the outer walls of the slide rods 502. A connecting plate 504 is fixed to the bottom center between the opposite sides of the two slide plates 503. A connecting shaft 505 is fixed to the bottom edge of the connecting plate 504. A vertical plate 506 is fixed to the top center of the slide plates 503. Clamps 507 are fixed to the opposite sides of the two vertical plates 506. A drive motor 508 is fixed to the bottom center of the inner cavity of the housing 501. A turntable 509 is fixed to the end of the output shaft of the drive motor 508. A vortex groove 510 is symmetrically formed at the top center of the turntable 509. The connecting shaft 505 is located in the vortex groove 510. Inside the housing 10, through slots are provided in the middle of both sides of the outer shell 501, and a moving slot is provided in the middle of the top of the outer shell 501, with the vertical plate 506 located inside the moving slot. Through the setting of the fixing mechanism 5, the back cover is placed between the two clamps 507. By starting the drive motor 508, the turntable 509 is driven to rotate, causing the vortex groove 510 to rotate, thereby causing the connecting shaft 505 to move inside the vortex groove 510, so that the connecting shaft 505 moves closer to the center of the turntable 509, thereby causing the connecting plate 504 to drive the sliding plate 503 to move closer to each other, and causing the vertical plate 506 to drive the clamps 507 to move closer to each other, clamping and fixing the back cover, thereby ensuring the stability during processing, preventing the back cover from shaking, and ensuring the processing quality.

[0033] In use, the following steps are taken: During processing, the back cover is placed between the two clamps 507. The power to the drive motor 508 is turned on, and the drive motor 508 is started. The start of the drive motor 508 drives the turntable 509 to rotate, causing the vortex groove 510 to rotate. This causes the connecting shaft 505 to move inside the vortex groove 510, bringing it closer to the center of the turntable 509. This, in turn, causes the connecting plate 504 to move the sliding plate 503 closer together, and the vertical plate 506 to move the clamps 507. The components are brought close together to clamp and fix the back cover. Then, the drive motor 508 is turned off. Before drilling the inclined oil hole, the knob 405 is turned. The knob 405 is screwed to the screw 404. When the knob 405 is turned, the screw 404 moves, thereby driving the connecting block 403 to move and changing the length of the screw 404 exposed outside the mounting cylinder 408. This causes the deflection plate 3 to drive the rotating shaft 401 to deflect and change the angle, thus facilitating the change of the angle during the processing of the back cover. Then, the inclined oil hole is drilled using a drilling machine.
