These two types of machine tools are inconvenient for multi-sided workpiece machining, requiring frequent workpiece repositioning and mounting, increasing the number of workpiece mounting operations, resulting in high workload and low efficiency.

[0028] The following is an embodiment of a machining spindle with an integrated water spray structure provided by the present invention that can solve the above technical problems.

[0029] Please refer to Figure 2 and Figure 3 ,in Figure 2 This is a structural schematic diagram of the machining spindle with an integrated water spray structure of the utility model. Figure 3 for Figure 2 In the figure, units with similar structures are represented by the same reference numerals.

[0030] This embodiment provides a machining spindle 11 with an integrated water spray structure, which includes: a vertical base 21, a lifting frame 22, a tool head assembly 23, a first driving member 24, a second driving member 25, and a third driving member. The first driving member 24, the second driving member 25 and the third driving member can all be motors.

[0031] The lifting frame 22 is slidably connected to the vertical base 21, and the lifting frame 22 is connected to the output end of the first driving member 24. The cutter head assembly 23 is connected to the bottom end of the lifting frame 22 by rotating around the first rotating shaft. The first rotating shaft is parallel or perpendicular to the lifting direction of the lifting frame 22. Figure 2 When the first rotating axis is parallel to the lifting direction of the lifting frame 22, the orientation of the cutter head assembly 23 can be adjusted to process the four sides of the stationary workpiece. When the first rotating axis is perpendicular to the lifting direction of the lifting frame 22, the orientation of the cutter head assembly 23 can be adjusted to process the top surface and two side surfaces of the stationary workpiece.

[0032] The cutter head assembly 23 is connected to the output end of the second drive member 25. A cutter 232 is mounted on one side of the cutter head assembly 23, rotating about a second axis. The second axis is perpendicular to the first axis. The cutter 232 is connected to the output end of the third drive member, driving the cutter 232 to rotate and cut the workpiece. The third drive member is disposed within the cutter head housing 231.

[0033] The cutter head assembly 23 of this embodiment can be rotated around the first rotating shaft to adjust the orientation of the cutter head assembly, thereby being able to perform multi-faceted processing on a fixed workpiece, reducing the number of workpiece assembly times, reducing workload, and improving efficiency.

[0034] In this embodiment, the lifting frame 22 includes a vertical plate 221 and a horizontal seat 222. The horizontal seat 222 is connected to the bottom end of one side of the vertical plate 221. The second driving member 25 and the cutter head assembly 23 are respectively arranged on both sides of the horizontal seat 222. When it is necessary to set the first rotating shaft to be perpendicular to the lifting direction of the lifting frame 22, it is only necessary to Figure 2 In the viewing orientation of FIG, this can be achieved by rotating the horizontal seat 222 on the vertical plate 221 by 90°.

[0035] Please refer to Figure 3 The output end of the second driving member 25 is connected to the cutter head assembly 23 through a transmission mechanism, which includes a transmission housing, a driving gear, a sun gear 262, planetary gears 263, a transmission plate 264, and a hollow shaft 265. The transmission housing is composed of an upper cover 261 and a lower housing 266.

[0036] The transmission housing is fixedly connected to the transverse seat 222, and the transmission disc 264 is rotatably disposed within the transmission housing. A hollow shaft 265 passes through the transmission housing and the transmission disc 264, and is fixedly connected to the transmission disc 264 and rotatably connected to the transmission housing. The output end of the second driving member 25 passes through the transmission housing and is connected to the driving gear. A ring gear is provided on the inner wall of the transmission housing, and the sun gear 262 is sleeved on the outer circumference of the hollow shaft 265. The sun gear 262 includes a first gear and a second gear distributed axially, the first gear being meshed with the driving gear. A plurality of planetary gears 263 are transmission-connected between the ring gear and the second gear. The planetary gears 263 are connected to the transmission disc 264, and the transmission disc 264 is connected to the cutter head assembly 23. In this way, the second driving member 25 can drive the transmission disc 264 to rotate through the driving gear, the sun gear 262, and the planetary gears 263, thereby driving the cutter head assembly 23 to rotate.

[0037] The machining spindle 11 with an integrated water spray structure in this embodiment also includes a water spray pipe 27, a water conduit connected to the water spray pipe 27, and an electrical wire connected to a third drive member. Multiple water spray pipes 27 are positioned on the same side of the cutter head assembly 23 as the tool 232, with the water outlets of each water spray pipe 27 facing the tool 232. The water conduit and electrical wires are housed within the hollow shaft 265. This clever and compact arrangement of the water conduit and electrical wires ensures they remain unaffected by the rotation of the cutter head assembly 23. Furthermore, the multiple water spray pipes 27 rotate with the cutter head assembly 23, ensuring consistent water spray at the workpiece processing location without requiring manual adjustment of the water spray direction.

[0038] The cutter head assembly 23 includes a cutter head housing 231 , in which a first water channel 235 for connecting the water pipe and the water spray pipe 27 is provided. The cutter head housing 231 is provided with a wiring through hole 234 for the wires to pass through.

[0039] In this embodiment, the cutter head assembly 23 further includes a connecting plate 233, to which multiple water spray pipes 27 are connected. The connecting plate 233 is connected to the cutter head housing 231. A second water conduit is provided within the connecting plate 233. When the connecting plate 233 is fixedly connected to the cutter head housing 231, the water spray pipes 27 are connected to the first water conduit 235 via the second water conduit. This allows for convenient simultaneous assembly and disassembly of multiple water spray pipes 27. Furthermore, the tortuous arrangement of the first water conduit 235 and the second water conduit allows for greater flexibility in the placement of the water spray pipes 27 and the water conduit.

[0040] Among them, a connecting hole is provided on the connecting plate 233, and a connecting head protruding from the connecting plate 233 is provided at the outer end of the connecting hole. A nut part 271 for threaded connection with the connecting head is rotatably provided on the water spray pipe 27. When the nut part 271 is connected to the connecting head, the water spray pipe 27 is sealed and inserted into the connecting hole, and the disassembly and assembly of the water spray pipe 27 is very convenient.

[0041] In addition, the water spray pipe 27 in this embodiment can be a universal water spray pipe 27, such as a bamboo tube or a bendable metal tube, so as to adjust the water spray direction.

[0042] Please refer to Figure 1 In this embodiment, a connecting groove is provided on the vertical base 21, and the lifting frame 22 is arranged in the connecting groove. Guide rails 211 are provided on three sides of the connecting groove, and sliding grooves are provided on three sides of the lifting frame 22 for slidingly cooperating with the guide rails 211. The lifting and sliding of the lifting frame 22 are very stable.

[0043] The machining spindle 11 with the integrated water spray structure can be applied to a horizontal and vertical integrated drilling and tapping machine.

[0044] Please refer to Figure 1 When the first rotating shaft is arranged parallel to the lifting direction of the lifting frame 22, the horizontal-vertical integrated drilling and tapping machine can also be provided with an auxiliary machining spindle 12, and the rotation axis of the tool 232 of the auxiliary machining spindle 12 is parallel to the lifting direction of the lifting frame 22. By adjusting the orientation of the tool head assembly 23 of the machining spindle 11, the four sides of a stationary workpiece can be machined separately, and the auxiliary machining spindle 12 can be used to machine the top surface of the stationary workpiece. Alternatively, the machining spindle 11 can machine one workpiece while the auxiliary machining spindle 12 machines another workpiece. When necessary, the machining spindle 11 and the auxiliary machining spindle 12 can be moved to the other workpiece to perform corresponding machining.

[0045] When the first rotating shaft is positioned perpendicular to the lifting direction of the lifting frame 22, the horizontal-vertical integrated drilling and tapping machine can also be provided with a rotating processing platform (the rotating processing platform is not illustrated in this embodiment). The processing platform is located below the machining spindle 11 and is used to secure the workpiece to be processed. The axis of rotation of the processing platform is parallel to the lifting direction of the lifting frame 22. By adjusting the orientation of the cutter head assembly 23 and coordinating the rotation of the processing platform, the top surface and four side surfaces of the stationary workpiece can be processed.

[0046] The cutter head assembly of the machining spindle of this embodiment can be rotated about a first rotation axis to adjust the orientation of the cutter head assembly, thereby enabling multi-faceted machining of a fixed workpiece, reducing the number of workpiece assembly times and workload, and improving efficiency. Furthermore, multiple water spray pipes are provided on the cutter head assembly, which rotate with the cutter head assembly to consistently spray water at the machining position of the workpiece, eliminating the need for manual adjustment of the water spray direction and further improving work efficiency.

[0047] In summary, although the present invention has been disclosed above by way of embodiments, the above embodiments are not intended to limit the present invention. A person skilled in the art may make various modifications and improvements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined by the claims.
