[0002] The head lathe is a device used to turn the end of the wire. Before reducing the diameter of the wire, the end of the wire needs to pass through the eye die. Therefore, the head lathe is needed to turn the end of the wire to reduce the diameter of the wire and pass through the eye die smoothly so that the mechanism behind the eye die can clamp the wire. The head lathe is provided with a tool holder for installing the turning tool. Since the turning tool installed on the existing turning tool holder can only turn the wire to a certain depth at a time, when the turning depth is greater than the single turning depth of the turning tool, two or even multiple turnings are required, which affects the turning efficiency, and the cutting depth adjustment of the tool is also more troublesome, affecting the processing efficiency.

[0018] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0019] like Figure 1-6As shown, a turning tool seat structure of a headstock machine comprises an annular base 1, an annular groove 2 is provided on one side of the base 1, at least two guide grooves 3 are evenly provided on one side of the base 1, the guide grooves 3 are connected to the groove 2, the depth of each guide groove 3 is different, a turning assembly is provided inside each guide groove 3, the turning assembly comprises a turning tool rod 4 slidably connected to the guide groove 3, a tool head 5 is provided at one end of the turning tool rod 4, a mounting groove is provided on the side of the turning tool rod 4 close to the groove 2, a limit plate 6 is provided inside the groove 2, and the limit plate 6 is located in the mounting groove Inside, a compressible pad 7 is provided on the side of the limit plate 6 away from the cutter head 5, and the pad 7 is located in the mounting groove. A rotatable bearing 8 is provided on the other side of the turning tool rod 4. A sleeve 9 is rotatably connected to one side of the base 1. A guide ring 10 is provided inside the sleeve 9. The inner side of the guide ring 10 contacts the outer surface of the bearing 8. When the guide ring 10 rotates, the distance moved by each turning tool rod 4 in the guide groove 3 is different. A locking bolt 11 is provided on the outer surface of the sleeve 9, and a card slot 12 for moving the locking bolt 11 is provided on the outer surface of the base 1.

[0020] The limit plate 6 and the pad 7 can limit the tool rod 4 in the guide groove 3, and can also reset the tool rod 4 through the compressed pad 7. When the tool rod 4 is reset, the tool rod 4 will move toward the outside of the base 1 under the action of the pad 7.

[0021] In this specific embodiment, there are four guide grooves 3 and four turning assemblies. Since the depths of the guide grooves 3 are different, the cutter heads 5 in the four guide grooves 3 turn the wire in sequence. The smaller the depth of the guide groove 3, the earlier the cutter head 5 in the guide groove 3 participates in the turning of the wire. The depths of the four guide grooves 3 increase successively. The depth of the first guide groove 3 is 20 mm, and the depths of the remaining three guide grooves 3 are 20.5 mm, 21 mm and 21.5 mm respectively. When turning the wire, the cutter head 5 in the guide groove 3 with a depth of 20 mm first participates in the turning of the wire, and the cutter head 5 in the guide groove 3 with a depth of 21.5 mm participates in the turning of the wire last.

[0022] The inner surface of the guide ring 10 has four arcs, each of which corresponds to the bearing 8. The curvature of the four arcs is different. When the sleeve 9 rotates, the inner side of the guide ring 10 will abut against the bearing 8, thereby pushing the cutter head 5 to move, so that the cutter head 5 moves toward the central axis of the base 1. After the sleeve 9 rotates a certain angle, the distances moved by the four cutter heads 5 are different, and the four cutter heads 5 divide the turning depth into four equal parts, that is, when the wire needs to be turned to a depth of 4mm, by rotating the sleeve 9, the four turning tool rods 4 on the base 1 are moved at the same time, and the cutter head 5 is moved toward the central axis of the base 1. When the cutter head 5 with the farthest moving distance is able to turn the wire to a depth of 4mm, the sleeve 9 stops rotating, and then passes The locking bolt 11 fixes the sleeve 9 on the base 1. At this time, the positions of the other three cutter heads 5 can respectively turn the wire at a depth of 3mm, 2mm and 1mm, and the cutter head 5 that can turn the wire at a depth of 1mm is the closest to the wire, and the cutter head 5 that can turn the wire at a depth of 4mm is the farthest from the wire. Therefore, when turning the wire, the cutter head 5 at the front can turn the front end of the wire at a depth of 1mm, and the remaining cutter heads 5 turn 2mm, 3mm and 4mm at the front end of the wire in turn, so that the actual turning depth of each cutter head 5 is 1mm each time, thereby reducing the turning depth of the cutter head 5, protecting the cutter head 5, and improving the turning efficiency.

[0023] Furthermore, when the guide ring 10 rotates, an identification line 13 is provided on the tool rod 4 with the longest moving distance, and a scale line 14 is provided on the base 1 and located on one side of the identification line 13. When adjusting the position of the tool rod 4, it is only necessary to compare the identification line 13 with the scale line 14 to observe whether the tool rod 4 with the longest moving distance has reached the predetermined position. If the tool rod 4 with the longest moving distance reaches the predetermined position, the other three tool rods 4 also reach the predetermined positions accordingly, thereby improving the adjustment efficiency of the tool head 5.

[0024] Furthermore, two groups of locking bolts 11 and slots 12 are provided, and the slots 12 are symmetrically arranged on the outer surface of the base 1. When the sleeve 9 is fixed on the base 1, the locking bolts 11 are rotated, and the bottom of the locking bolts 11 contacts the bottom of the slots 12. The friction force generated can limit the rotation of the sleeve 9. At the same time, since the lower end of the locking bolts 11 is located in the slots 12, the sleeve 9 can be prevented from falling off the outer surface of the base 1.

[0025] Furthermore, a slider 15 is threadedly connected to the screw rod of the locking bolt 11, and the slider 15 is slidably connected to the slot 12. The slider 15 is located in the slot 12 and can only move in the slot 12 but cannot rotate in the slot 12. When the locking bolt 11 is not tightened, the slider 15 can improve the stability of the sleeve 9 when it rotates on the base 1.

[0026] Furthermore, a cylinder 16 is provided at one end of the base 1 , and a connecting hole 17 is provided on the cylinder 16 , which is connected to the output shaft of the external power device by bolts through the cylinder 16 and the connecting hole 17 .

[0027] This type of turning tool holder can simultaneously install multiple cutter heads 5, and the turning depth and distance between each cutter head 5 and the front end of the wire are different, so that the multiple cutter heads 5 on the turning tool holder can perform multiple turnings of different depths on the front end of the same wire, thereby improving the turning efficiency of the wire, and the cutting depths of all cutter heads 5 can be adjusted at the same time, which is easy to adjust and has a good use effect.

[0028] In the description of this utility model, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.
