[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model is a double-layer tool head for CNC lathes, comprising:
[0007] A cutter head assembly, comprising an upper cutter head, a blade, a fixed base, and a mating groove;
[0008] The fixing component includes a lower cutter head, positioning rods, positioning rings, mounting rings, inner grooves, positioning holes, a rotating shaft, side plates, and a pressure plate. The lower cutter head is located on the lower surface of the upper cutter head. The mounting ring is installed between the upper and lower cutter heads. Multiple positioning holes are opened inside both the upper and lower cutter heads. Multiple positioning rods are connected to the top and bottom of the mounting ring and are inserted into the positioning holes.

[0010] Furthermore, it also includes a reinforcing component, which includes a rubber block and a limiting semi-ring. The rubber block is symmetrically connected to the top of the inner surface of the groove. The rubber block is located at the top of the pressure plate. The limiting semi-ring is connected to the bottom of the pressure plate and fits against the outer surface of the positioning ring.
[0011] Furthermore, the upper and lower cutter discs have multiple mating grooves on their outer surfaces, the fixing seat is embedded in the mating grooves, and the blade is connected to one side of the outer surface of the fixing seat.
[0012] Furthermore, it also includes positioning components, which include insertion holes, spheres, upright plates, support rods, springs, limiting discs, support frames, support plates, slide grooves, sliders, insert rods, and fixing grooves. Insertion holes are provided at the top of the upper cutter disc, inside the fixing seat, and at the bottom of the lower cutter disc. Insert rods are inserted and connected inside the insertion holes. Fixing grooves are symmetrically provided on the lower part of the outer surface of the insert rod. Multiple upright plates are respectively connected to the bottom of the upper cutter disc and the top of the lower cutter disc. Support rods are connected to one side of the upright plates.

[0033] Please see Figure 1-7 As shown, this embodiment is a double-layer tool head for a CNC lathe, including:
[0034] The cutter head assembly includes an upper cutter head 11, a blade 12, a fixed base 13, and a docking groove 14;
[0035] The fixing component includes a lower cutter head 21, a positioning rod 22, a positioning ring 23, a mounting ring 24, an inner groove 25, a positioning hole 26, a rotating shaft 27, a side plate 28, and a pressure plate 29. The lower cutter head 21 is located on the lower surface of the upper cutter head 11. The mounting ring 24 is installed between the upper cutter head 11 and the lower cutter head 21. Multiple positioning holes 26 are opened inside both the upper cutter head 11 and the lower cutter head 21. Multiple positioning rods 22 are connected to the top and bottom of the mounting ring 24. The positioning rods 22 are inserted into the positioning holes 26. Multiple positioning rings 23 are connected to the top of the upper cutter head 11 and the bottom of the lower cutter head 21. The positioning rings 23 are embedded in the outer surface of the positioning rods 22.
[0036] The positioning rod 22 is inserted into the positioning hole 26, while the positioning ring 23 is simultaneously embedded in the upper rotating side plate 28 on the outer surface of the positioning rod 22. The pressure plate 29 is adjusted and pressed into the inner groove 25 to fix the position of the positioning rod 22 after insertion. In this way, the upper cutter head 11, the lower cutter head 21 and the mounting ring 24 will be installed together to achieve the effect of a double-layer cutter head.
[0037] The upper part of the outer surface of the positioning rod 22 is provided with an inner groove 25, the outer surface of the positioning ring 23 is symmetrically connected with a rotating shaft 27, the side plate 28 is rotatably connected to the outer surface of the rotating shaft 27, and the pressure plate 29 is connected to the upper part of one side of the side plate 28 and pressed into the inner groove 25.
[0038] The pressure plate 29 is pressed into the inner groove 25 by rotation and snap-fit, positioning the inserted positioning rod 22.
[0039] It also includes a reinforcing component, which includes a rubber block 31 and a limiting half-ring 32. The top of the inner surface of the inner groove 25 is symmetrically connected with the rubber block 31, which is located on the top of the pressure plate 29. The limiting half-ring 32 is connected to the bottom of the pressure plate 29 and fits against the outer surface of the positioning ring 23.
[0040] After the pressure plate 29 is pressed into the interior of the groove 25, the rubber block 31 is pressed against the top of the pressure plate 29 to prevent the pressure plate 29 from becoming loose.
[0041] Multiple mating grooves 14 are provided inside the outer surfaces of the upper cutter head 11 and the lower cutter head 21. The fixing seat 13 is embedded in the inside of the mating groove 14, and the blade 12 is connected to one side of the outer surface of the fixing seat 13.
[0042] Insert the fixing seat 13 into the docking groove 14 in sequence, so that the blade 12 is installed on the outside of the upper blade disc 11 and the lower blade disc 21 in sequence.
[0043] The working principle is as follows: First, the positioning rod 22 is inserted into the positioning hole 26, so that the upper cutter head 11 is installed on the top of the mounting ring 24, and the lower cutter head 21 is installed on the bottom of the mounting ring 24. At the same time, the positioning ring 23 is embedded in the upper rotating side plate 28 on the outer surface of the positioning rod 22. The pressure plate 29 is adjusted and pressed into the inner groove 25 to fix the position of the positioning rod 22 after insertion. The rubber block 31 is pressed on the top of the pressure plate 29, and the limiting half ring 32 is clamped on the outer surface of the positioning rod 22 to prevent the pressure plate 29 from loosening. In this way, the upper cutter head 11, the lower cutter head 21 and the mounting ring 24 are installed together to achieve the effect of a double-layer cutter head, which multiplies the number of cutters on the cutter head without increasing the diameter of the cutter head, which is beneficial to improving the processing efficiency of the workpiece.
[0044] Please see Figure 1-7 As shown, this embodiment, based on the above embodiment, further includes a positioning component. The positioning component includes an insertion hole 41, a ball 42, a vertical plate 43, a support rod 44, a spring 45, a limiting plate 46, a support frame 47, a support plate 48, a sliding groove 49, a slider 491, an insertion rod 492, and a fixing groove 493. Insertion holes 41 are provided on the top of the upper cutter head 11, inside the fixing seat 13, and at the bottom of the lower cutter head 21. The insertion rod 492 is inserted and connected inside the insertion hole 41, and its outer surface... The lower part is symmetrically provided with fixing grooves 493. Multiple upright plates 43 are respectively connected to the bottom of the upper cutter head 11 and the top of the lower cutter head 21. The support rod 44 is connected to one side of the upright plate 43. The spring 45 is wound and connected to the outer surface of the support rod 44. The support rod 44 is connected through the inside of the support frame 47.

The ball 42 is connected to one side of the outer surface of the support frame 47 and is embedded in the inside of the fixing groove 493.
[0045] The ball 42 extends and retracts to one side due to the elastic force generated by the spring 45. When the insertion rod 492 extends to the bottom, the spring 45 rebounds, fixing the ball 42 inside the fixing groove 493 and fixing the position of the insertion rod 492 after insertion.
[0046] The support plate 48 is connected to the bottom and top of the upper cutter head 11 respectively. The support plate 48 has a groove 49 inside. The slider 491 is connected to both ends of the outer surface of the support frame 47 and is movably connected inside the groove 49.
[0047] When the spring 45 generates elastic force, the support frame 47 moves, causing the slider 491 to slide inside the groove 49, which can support the support frame 47.
[0048] The working principle is as follows: First, the fixing seat 13 is inserted into the docking groove 14 to install the blade 12. Then, the insertion rod 492 is inserted into the insertion hole 41. Through the elastic force generated by the spring 45, the ball 42 extends and retracts to one side. When the insertion rod 492 extends to the bottom, the spring 45 rebounds, so that the ball 42 is fixed inside the fixing groove 493, and the position of the insertion rod 492 after insertion is fixed, so as to achieve reliable fixation of the blade 12 after installation.
