[0017] The following is a more detailed description of the specific embodiment of the utility model by referring to the drawings and describing the embodiments, so as to help those skilled in the art have a more complete, accurate and in-depth understanding of the concept and technical solution of the utility model.

[0018] As Figures 1-3 shown, the utility model provides a cylinder drilling device, including a frame 1, a clamping mechanism 3 and a drilling mechanism 4. Limiting plates 2 are symmetrically arranged on both sides of the frame 1, and a limiting groove 21 for placing a workpiece is arranged in each limiting plate 2. The clamping mechanism 3 is arranged on the frame 1 and is used for simultaneously fixing the workpieces in the two limiting grooves 21. Two drilling mechanisms 4 are arranged symmetrically on both sides of the frame 1.

[0019] It should be noted that the clamping mechanism 3 includes a rotating plate 31, a first cylinder 33, a connecting plate 32 and a pressing plate 34. There are two rotating plates 31 which are symmetrically arranged on the frame 1. A connecting plate 32 is arranged on the side surface of each rotating plate 31. One end of each connecting plate 32 is rotatably connected to the rotating plate 31 through a pin shaft, and the other end of the connecting plate 32 is rotatably connected to the frame 1 through a pin shaft. The cylinder block of the first cylinder 33 is rotatably connected to the frame 1 through a pin shaft, and the piston rod of the first cylinder 33 is rotatably connected to one of the rotating plates 31 through a pin shaft. A pressing plate 34 is arranged at the lower end of each rotating plate 31. The two rotating plates 31 are connected through a fixing component 35. The fixing component 35 includes a fixing block 351 and a main board 352. A plurality of fixing blocks 351 are arranged on the side surfaces of the rotating plates 31. The fixing block 351 is of an "L" - shaped structure. The fixing blocks 351 on different rotating plates 31 are connected through the same main board 352. By connecting the two rotating plates 31 through the fixing component 35, the two pressing plates 34 can be driven by one first cylinder 33 to press two workpieces at the same time.

[0020] In addition, the drilling mechanism 4 includes a support rod 41, a support plate 42, a second cylinder 43 and a drilling motor 44. The support plate 42 is arranged on the support rod 41 on the frame 1. The cylinder block of the second cylinder 43 is installed on the support plate 42 and a drilling motor 44 is arranged at the lower end of its piston rod. A drill bit 45 is arranged on the output shaft of the drilling motor 44.

[0021] Specific implementation method and principle:

[0022] When the present utility model is actually applied, the compressor cylinders to be drilled are respectively placed in the limit grooves 21 on the limit plates 2 on both sides of the frame 1. Then, control the piston rod of the first cylinder 33 to drive the rotating plate 31 to rotate, and drive the rotating plate 31 on the other side of the frame 1 to rotate synchronously through the fixing block 351 and the main board 352 of the fixing component 35. The compressor cylinders in the limit grooves 21 are tightly fixed by the pressing plates 34 at the bottom of the rotating plates 31. Then, control the piston rod of the second cylinder 43 to extend to drive the drilling motor 44 to move downward, and the drill bit 45 on the output shaft of the drilling motor 44 drills the compressor cylinders.

[0023] To sum up, through the two rotating plates 31 and the pressing plates 34 on the clamping mechanism 3, the cylinder blocks in the limit grooves 21 on both sides of the frame 1 can be tightly clamped simultaneously under the drive of the first cylinder 33, and the cylinder blocks are drilled by the drilling motors 44 on the two drilling mechanisms 4, thereby improving the drilling efficiency of the cylinder blocks.

Obviously, the specific implementation of the present utility model is not limited by the above-mentioned manner. As long as various non-substantive improvements are made by adopting the concept and technical solution of the present utility model, or the present utility model and technical solution are directly applied to other occasions without improvement, they are all within the protection scope of the present utility model.
