Detailed Implementation

[0016] The present invention will be further illustrated below with reference to specific examples and accompanying drawings.

[0017] like Figures 1-4As shown, a CNC feed machine for wire processing includes a frame 1. A vertical plate 2 is fixedly mounted on the left side of the frame 1. A wire rotating device 3 is provided at the lower part of the vertical plate 2. The wire rotating device 3 passes through the vertical plate 2 and the wire feeding direction is perpendicular to the plane of the vertical plate 2. Three vertical tool holders 4 are provided on the upper part of the vertical plate 2. Each vertical tool holder 4 includes a vertical tool holder mounting base 41, a vertical lead screw motor 42, a vertical sliding tool holder 43, and a vertical tool 44. The vertical tool holder mounting base 41... Fixed on the vertical plate 2, the vertical screw motor 42 is mounted on the upper part of the vertical blade holder mounting base 41. The lower part of the vertical blade holder mounting base 41 is provided with a vertical slide rail. The vertical slide rail is a double linear track, which helps to ensure the stability of the vertical sliding blade holder 43 when sliding. The vertical sliding blade holder 43 is driven by the vertical screw motor 42 to move up and down along the vertical slide rail. The vertical blade 44 is mounted on the lower part of the vertical sliding blade holder 43. The sliding direction of the vertical blade 44 points to the axis of the wire rotating device 3. The wire rotating device 3 is provided with side-moving tool holders 5 on both sides along the wire feeding direction. Each side-moving tool holder 5 includes a side tool holder mounting base 51, a longitudinal lead screw motor 52, a longitudinal slide block 53, a transverse lead screw motor 54, a transverse slide block 55, and a side tool holder 56. The side tool holder mounting base 51 is fixed on the frame 1. The longitudinal lead screw motor 52 is mounted on the side tool holder mounting base 51. The longitudinal slide block 53 is driven by the longitudinal lead screw motor 52, and its lower surface moves laterally against the upper surface of the frame 1. The transverse lead screw motor 54 is fixedly mounted on the longitudinal slide block 53. The transverse slide block 55 slides along the upper surface of the longitudinal slide block 53 under the drive of the transverse lead screw motor 54. The side tool holder 56 is fixedly mounted on the transverse slide block 55. The side tool holder 56 is provided with a tool head mounting groove, and the tool head is fixed in the tool head mounting groove by bolts for easy tool head replacement. The frame 1 on the left side of the vertical plate 2 is equipped with a wire rotation transmission device 6. The wire rotation transmission device 6 drives the wire rotation device 3 to rotate. The wire rotation device 3 is provided with a telescopic fixing claw for clamping the wire. When the fixing claw retracts, it releases the wire, and when it extends, it clamps the wire. An axial drilling and tapping device 7 is provided on the right side of the frame 1. The axial drilling and tapping device 7 includes a drill bit holder slide rail 71. A drill bit holder slide drive motor 73 is fixedly installed at one end of the drill bit holder slide rail 71. A drill bit holder slide 72 placed on the drill bit holder slide rail 71 is driven by the drill bit holder slide drive motor 73 to move longitudinally on the drill bit holder slide rail 71. A drill bit holder 74 is provided on the drill bit holder slide 72. The drill bit holder 74 is provided with three drill bit rods that are parallel to each other and face the end face of the wire. An axial drive motor 75 is provided on the frame 1 on the right side of the drill bit holder slide rail 71. The axial drive motor 75 drives a drill bit push block 76 to move axially along the wire clamped by the wire rotating device 3. The drill bit push block 76 pushes the drill bit rods on the drill bit holder 74 facing the wire towards the end face of the wire.

[0018] The frame 1 is surrounded by a barrier 11 for collecting metal shavings generated during wire processing.

[0019] The rear side of the frame 1 is also equipped with a touch screen control box 8. The control devices in the touch screen control box 8 are respectively connected to the vertical lead screw motor 42, the longitudinal lead screw motor 52, the transverse lead screw motor 54, the drill bit holder slide drive motor 73, and the drill bit axial drive motor 75. The vertical lead screw motor 42, the longitudinal lead screw motor 52, the transverse lead screw motor 54, the drill bit holder slide drive motor 73, and the drill bit axial drive motor 75 are all high-precision lead screw motors.

[0020] The central axis of the lead screw of the transverse lead screw motor 54 is parallel to the central axis of rotation of the wire rotating device 3.

[0021] This utility model designs a CNC feed machine for wire processing. When processing wire with a circular cross-section and a small radius, the operating parameters of the corresponding motors for the cutter and drill are set in advance according to the shape requirements of the parts to be processed. The CNC feed machine automatically completes operations such as grooving, cutting or texturing, drilling or tapping on the outer edge of the wire. The wire is installed in the wire rotating device 3, which is driven by the wire rotating transmission device 6. As the wire rotates with the wire rotating device 3, the vertical screw motor 42 on the vertical tool holder mounting base 41 of the grooving vertical tool holder 4 drives the vertical sliding tool holder 43 to push the vertical tool 44 into the wire to carve an annular groove, and then retracts the tool. For example, to carve a spiral groove, a side-moving tool holder 5 is used. The longitudinal lead screw motor 52 on the side tool holder mounting base 51 drives the cutter head on the side tool holder 56 to advance by pushing the longitudinal slide 53. At the same time, the transverse lead screw motor 54 drives the transverse slide 55 to move the cutter head on the side tool holder 56 laterally, thus completing the machining of the spiral pattern. After machining, the tool is retracted. While the wire is being grooved or textured on the side, the front end of the wire along the feeding direction is also being drilled or tapped using the axial drilling and tapping device 7. During drilling or tapping, the drill bit holder slide 72, which is placed on the drill bit holder slide rail 71, is driven by the drill bit holder slide drive motor 73 to move longitudinally on the drill bit holder slide rail 71, thereby selecting the corresponding drill bit rod of the drill bit holder 74. Then, the drill bit axial drive motor 75 drives the drill bit push block 76 to move axially along the wire clamped by the wire rotating device 3. The drill bit push block 76 pushes the drill bit rod on the drill bit holder 74, which is facing the wire, to feed into the end face of the wire. The drilling or tapping is completed when the wire rotates. After drilling or tapping is completed, the drill bit push block 76 is pulled back by the drill bit axial drive motor 75, and the drill bit rod automatically springs back, completing the retraction. After completing the grooving or texturing of the wire side and the drilling or tapping operations along the wire axis, the cutting tool holder 4 finally cuts the wire. When the telescopic fixed claw in the wire rotating device 3 retracts, it releases the wire. The feeding device pushes the wire to the right by one part length, and then the telescopic fixed claw extends to clamp the wire, completing the step feeding. This process is repeated to complete the batch processing of parts of the same model. When switching to processing another batch of parts with different specifications and sizes, the corresponding motor operating parameters can be imported into the CNC feed machine. However, due to the special structure of the cam machine, its production models are relatively fixed and inconvenient to change. Therefore, the CNC feed machine for wire processing of this utility model facilitates production model changes, has a high degree of automation, and high processing efficiency.

[0022] The above embodiments are merely preferred embodiments of the present utility model and are only used to explain the present utility model, not to limit the present utility model. Any changes, substitutions, combinations, simplifications, modifications, etc., made by those skilled in the art without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
