[0030] Please refer to Figure 1 ,in Figure 1 This is a structural schematic diagram of a machining spindle with a wire harness clamping structure according to the present invention.

[0031] This embodiment provides a machining spindle with a wire harness clamping structure, which includes: a spindle base 12, a cutter head assembly 13, a first driving member 14, a second driving member arranged in the cutter head assembly 13, a transmission mechanism 15, and an electric wire connected to the second driving member. The transmission mechanism 15 is connected between the first driving member 14 and the cutter head assembly 13. A tool 132 is provided on one side of the cutter head assembly 13, and the tool 132 is connected to the output end of the second driving member.

[0032] The transmission mechanism 15 includes a transmission housing 151 and a hollow shaft 152 that passes through the transmission housing 151. The transmission housing 151 is installed on the spindle base 12, and the wires are installed in the hollow shaft 152. The wires are located inside the hollow shaft 152. Although they are slightly loose, they do not appear messy. When the spindle base 12 and the cutter head assembly 13 move relative to each other, the wires are not easily pulled and damaged. The cutter head assembly 13 includes a cutter head housing 131. The cutter head housing 131 is provided with a wiring hole 1311 for the wires to pass through. The wiring hole 1311 is staggered with the port of the hollow shaft 152, so that when the cutter head housing 131 is connected to the transmission mechanism 15, the wires are limited between the cutter head housing 131 and the transmission mechanism 15, so that the wires are stably arranged and the connection between the wires and the cutter head assembly 13 is not easily pulled off and damaged.

[0033] The transmission housing 151 in this embodiment is composed of an upper cover 1511 and a lower housing 1512. The first driving member 14 and the second driving member can both be motors.

[0034] Please refer to Figure 2 In this embodiment, a limiting groove is also provided on the cutter head housing 131, and the wiring through hole 1311 is provided in the limiting groove. Part of the limiting groove is opposite to the port of the hollow shaft 152, so that the wire can extend from the hollow shaft 152 into the limiting groove and be confined in the limiting groove.

[0035] Specifically, the limiting groove includes a circular main groove portion 1312 and a branch groove portion 1313 connected to the peripheral side of the main groove portion 1312. The branch groove portion 1313 is in the shape of an elongated strip. The main groove portion 1312 is opposite to the port of the hollow shaft 152. The branch groove portion 1313 is staggered with the port of the hollow shaft 152. The wiring through hole 1311 is arranged in the branch groove portion 1313. After the cutter head housing 131 is connected to the transmission mechanism 15, the wires can be stably arranged in the branch groove portion 1313.

[0036] The machining spindle with a harness-fastening structure in this embodiment also includes a water spray pipe 134 and a water guide pipe. Multiple water spray pipes 134 are disposed on the side of the cutter head assembly 13 where the cutter 132 is located, with the water outlets of the multiple water spray pipes 134 all directed toward the cutter 132. The multiple water spray pipes 134 rotate along with the cutter head assembly 13, ensuring consistent water spray at the workpiece processing location without requiring manual adjustment of the water spray direction.

[0037] The water guide pipe is disposed in the hollow shaft 152 , and a first water guide channel 1314 for connecting the water guide pipe and the water spray pipe 134 is disposed in the cutter head housing 131 .

[0038] The cutter head assembly 13 further includes a connecting plate 133, to which multiple water spray pipes 134 are connected. The connecting plate 133 is connected to the cutter head housing 131. A second water channel is provided in the connecting plate 133. When the connecting plate 133 is fixedly connected to the cutter head housing 131, the water spray pipes 134 are connected to the first water channel 1314 via the second water channel. This allows for convenient assembly and disassembly of multiple water spray pipes 134 at the same time. Furthermore, the zigzag arrangement of the first water channel 1314 and the second water channel allows for more flexible positioning of the water spray pipes 134 and the water channel.

[0039] A connecting hole is provided on the connecting plate 133, and a connecting head protruding from the connecting plate 133 is provided at the outer end of the connecting hole. A nut piece for threaded connection with the connecting head is rotatably provided on the water spray pipe 134. When the nut piece is connected to the connecting head, the water spray pipe 134 is sealed and inserted into the connecting hole.

[0040] Please refer to Figure 3 The transmission mechanism 15 in this embodiment further includes a driving gear, a sun gear 153 , planetary gears 154 , and a transmission plate 155 .

[0041] The transmission disc 155 is rotatably disposed in the transmission housing 151 . The hollow shaft 152 penetrates the transmission disc 155 . The hollow shaft 152 is fixedly connected to the transmission disc 155 . The hollow shaft 152 is rotatably connected to the transmission housing 151 .

[0042] The output end of the first drive member 14 extends into the transmission case and connects to the driving gear. A ring gear is provided on the inner wall of the transmission case 151. A sun gear 153 is sleeved onto the outer circumference of the hollow shaft 152. The sun gear 153 includes a first gear and a second gear arranged axially. The first gear meshes with the driving gear. A plurality of planetary gears 154 are drivingly connected between the ring gear and the second gear. The planetary gears 154 are connected to a transmission disc 155, which is in turn connected to the cutter head assembly 13. Thus, the first drive member 14, through the driving gear, sun gear 153, and planetary gears 154, drives the transmission disc 155 to rotate, thereby driving the cutter head assembly 13.

[0043] Please refer to Figure 2 The machining spindle with a wire harness securing structure in this embodiment further includes a fixing plate 16, which is connected between the cutter head housing 131 and the transmission plate 155. The fixing plate 16 is provided with a docking through-hole 161 that is opposite to the main body groove 1312. When the fixing plate 16 is connected to the cutter head housing 131, the fixing plate 16 presses the wires into the branch groove 1313. This allows the fixing plate 16 to be fixedly connected to the cutter head housing 131, thereby forming a stable connection between the wires and the cutter head assembly 13. This prevents damage to the connection between the wires and the cutter head assembly 13 due to pulling during subsequent transportation and assembly.

[0044] The diameter of the main groove portion 1312 is larger than the width of the branch groove portion 1313 , and the diameter of the docking through hole 161 is smaller than the inner diameter of the main groove portion 1312 , so that the fixing plate 16 can better restrict the wires.

[0045] In addition, a water conducting through hole 162 is also provided on the fixing plate 16 corresponding to the first water conducting channel 1314 .

[0046] Please refer to Figure 1 and Figure 3 In this embodiment, the spindle base 12 includes a first plate 121 and a second plate 122 connected in an L-shaped structure. A reinforcing plate 123 is connected between the first plate 121 and the second plate 122. The first plate 121 is used to connect to the movable frame 11, and the transmission mechanism 15 is disposed on the second plate 122. A protective cover 17 for enclosing the first drive member 14 and the transmission mechanism 15 can also be connected to the movable frame 11. The movable frame 11 is slidably mounted on the crossbeam of the machine tool and can drive the spindle base 12 to rise and fall, as well as slide horizontally along the crossbeam, so as to process various predetermined positions of the workpiece.

[0047] The machining spindle with a harness-fastening structure of this embodiment can be used in a horizontal-vertical integrated drilling and tapping machine. The cutter head assembly 13 is connected to one side of the spindle base 12 by rotating about a first axis, and the cutting tool 132 is mounted on one side of the cutter head assembly 13 by rotating about a second axis, the second axis being perpendicular to the first axis. Rotating about the first axis, the cutter head assembly 13 can be adjusted in position, enabling multi-faceted machining of a fixed workpiece, reducing workpiece assembly times and workload, and improving efficiency.

[0048] Before assembling the machining spindle with a wire harness securing structure of this embodiment, the fixing plate 16 is first fixedly connected to the cutter head housing 131, thereby ensuring a stable connection between the wires and the cutter head assembly 13 and preventing damage to the connection between the wires and the cutter head assembly 13 due to pulling. The wires and the water conduit are then passed through the hollow shaft 152, and the fixing plate 16 is connected to the transmission disc 155 of the transmission mechanism 15.

[0049] The processing spindle with a wiring harness clamping structure in this preferred embodiment is achieved by arranging a hollow shaft in the transmission mechanism, and the wires are arranged in the hollow shaft. The wiring through hole on the cutter head housing is staggered with the port of the hollow shaft, so that when the cutter head housing is connected to the transmission mechanism, the wires are cleverly and compactly limited between the cutter head housing and the transmission mechanism, with good protection effect. The wires are located inside the hollow shaft and do not appear messy even if they are slightly loose. When the spindle base and the cutter head assembly move relative to each other, the wires are not easily pulled and damaged.

[0050] To sum up, although the utility model has disclosed above with preferred embodiment, the preferred embodiment above is not used to limit the utility model, ordinary skilled in the art can make various changes and decorations without departing from the spirit and scope of the utility model, therefore the protection scope of the utility model is accurate with the range defined by claim.
