Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] This utility model provides, for example Figures 1 to 4 The multi-axis deep hole drilling machine shown includes a drill table 1, a spindle head 2, a multi-axis drill 3, a positioning frame 4, and a spray cooling component. The spindle head 2 is mounted on the drill table 1. A drive spindle 22 is installed between the multi-axis drill 3 and the spindle head 2. The positioning frame 4 is fixedly mounted on the drill table 1, and a positioning plate 43 that can be adjusted vertically along the positioning frame 4 is fixedly mounted on the positioning frame 4. The output end of the multi-axis drill 3 passes through the positioning plate 43 to limit the stroke of the multi-axis drill 3. The spray cooling component is mounted on the drill table 1 and is used to cool the workpiece.

[0020] The positioning frame 4 includes a support base 41 fixedly mounted on the drilling platform 1. Columns 42 are fixedly mounted on both sides of the support base 41. The positioning plate 43 can be selectively installed at any height on the outer wall of the column 42 by means of nuts.

[0021] A drill bit 32 is fixedly installed at the output end of the multi-axis drill 3, and a through slot 46 adapted to the drill bit 32 is provided on the positioning plate 43.

[0022] Both sides of the multi-axis drill 3 are fixedly equipped with lifting guide sleeves, which are movably sleeved on the outer wall of the column 42.

[0023] A guide rail 44 is fixedly installed on the positioning plate 43. The top of the guide rail 44 moves through the lifting guide sleeve. A spring 45 is movably sleeved on the outer surface of the bottom end of the guide rail 44. A workpiece holder 5 for limiting the position of the workpiece is installed on the support base 41 directly opposite the through slot 46. By pre-adjusting the height of the positioning plate 43, when the drill bit 32 descends, the lifting guide sleeve moves downward synchronously, so that the spring 45 is compressed. When the spring 45 is compressed to the limit, the transmission spindle 22 drives the multi-axis drill 3 to rise, thereby realizing the control of the drilling depth. The through slot 46 is used to position the drill bit 32 to prevent it from deflecting during drilling due to its excessive length.

[0024] A mounting column 23 is fixedly installed on the top of the drilling platform 1, and the spindle head 2 is fixedly installed on the mounting column 23. The drive spindle 22 is installed in the spindle head 2 and moves up and down.

[0025] A start / stop switch 24 is fixedly installed on the outer wall of the spindle head 2, and an operation panel 6 is fixedly installed on the drilling platform 1. The start / stop switch 24 is used to control the start and stop of multiple spindle heads 2, and the operation panel 6 is used to adjust parameters such as drilling depth and drilling speed.

[0026] The spray cooling component includes a universal nozzle 9 mounted on the positioning plate 43 and a circulating water tank 7 installed inside the drilling platform 1.

A drain pipe is fixedly installed on the drilling platform 1, and a filter basket is placed on the circulating water tank 7. The bottom end of the drain pipe is directly opposite the filter basket. During the drilling process, the circulating pump 8 draws up the coolant in the circulating water tank 7, and the angle of the universal nozzle 9 is adjusted so that the coolant is sprayed directly onto the drilling position. The sprayed coolant, carrying metal shavings, falls into the filter basket through the drain pipe for filtration. The filtered coolant flows back to the circulating water tank 7, thus achieving recycling.

[0027] Working principle: When using this device, the workpiece is placed inside the workpiece holder 5, and then the spindle head 2 is started. At this time, the spindle head 2 drives the transmission spindle 22 to rotate and move the transmission spindle 22 downward. The transmission spindle 22 drives the multi-axis drill 3 to move downward and simultaneously drives multiple drill bits 32 to rotate synchronously. At this time, the drill bits 32 move downward along the through groove 46 to drill holes in the workpiece. Before drilling, the height of the positioning plate 43 is pre-adjusted. When the drill bit 32 descends, the lifting guide sleeve moves downward synchronously, which compresses the spring 45. When the spring 45 is compressed to the limit, the transmission spindle 22 drives the multi-axis drill 3 to rise, thereby realizing the control of drilling depth. The through slot 46 is used to position the drill bit 32 to prevent it from deflecting during drilling due to its excessive length. During the drilling process, the coolant in the circulating water tank 7 is drawn up by the circulating pump 8, and the angle of the universal nozzle 9 is adjusted so that the coolant is sprayed directly at the drilling position. The sprayed coolant, carrying metal shavings, falls into the filter basket through the drain pipe for filtration. The filtered coolant flows back to the circulating water tank 7, thus realizing recycling.
