[0032] Reference Figure 1-5 ,

[0033] A fastener lathe comprises: a lathe body 10, a clamping member 20, a movable tool holder 30, a turning tool 40 and a drill 50. In the present embodiment, the clamping member 20 is a three-jaw chuck for clamping a cylindrical fastener blank. The clamping member 20 is mounted on the lathe body 10, and the lathe body 10 drives the clamping member 20 to rotate around the axis of the clamping member 20 itself, and the clamping member 20 drives the blank to rotate at high speed. The movable tool holder 30 is an existing slide box with a tool holder, and the turning tool 40 is fixed to the movable tool holder 30 by bolts. The lathe body 10 makes the movable tool holder 30 reciprocate along a fixed straight line, and the fixed straight line is parallel to the axis of the clamping member 20, so that the movable tool drives the turning tool 40 to cut and round the rotating blank. The drill bit 50 is installed on one end of the lathe body 10 away from the clamping member 20. The drill bit 50 faces the clamping member 20, and the axis of the drill bit 50 coincides with the axis of the clamping member 20. When the clamping member 20 drives the blank to rotate at high speed, the lathe body 10 makes the drill bit 50 approach the blank and drill a hole on the center axis of the blank, thereby realizing the simultaneous processing of the blank and drilling.

[0034] Specifically, it also includes: an illumination lamp 60. The movable tool holder 30 is installed on one side of the lathe body 10, and the illumination lamp 60 is placed on the other side of the lathe body 10. When the turning tool 40 cuts the blank, sometimes the light is dim, which is not conducive to the worker to observe the flatness of the cutting surface. The illumination lamp 60 is needed to supplement the light at the cutting position of the turning tool 40 to increase the brightness, so as to facilitate the worker to observe.

[0035] Specifically, a guide plane is formed on the upper surface of the lathe body 10, and the guide plane is parallel to the fixed straight line. The length direction of the guide plane is the same as the direction of the fixed straight line. The movable tool holder 30 forms a contact plane facing downward, and the contact plane and the guide plane slide together. The guide plane supports the movement of the movable tool holder 30, so that when the movable tool holder 30 moves, the height of the turning tool 40 is kept consistent, and at the same time, the vibration of the turning tool 40 when cutting the blank is reduced during movement, so as to improve the cutting quality of the turning tool 40.

[0036] Specifically, the lathe body 10 includes: a frame 11, a power member, a lead screw 12 and a first guide rod 13. The upper end of the frame 11 forms a guide plane, the power member is a motor, and the power member is fixedly mounted on the frame 11 by bolts. The two ends of the first guide rod 13 are fixed on the frame 11, the output end of the power member is connected to one end of the lead screw 12 by a coupling, and the other end of the lead screw 12 is rotatably connected to the frame 11. The axis of the lead screw 12 is parallel to the axis of the first guide rod 13, and the axis of the lead screw 12, the axis of the first guide rod 13 and the moving direction of the movable tool holder 30 are parallel to each other. The lead screw 12 is threadedly connected to the movable tool holder 30, and the first guide rod 13 penetrates the movable tool holder 30 to guide the movable tool holder 30. When the power member is started, the lead screw 12 is driven to rotate, and the lead screw 12 drives the threaded movable tool holder 30 to reciprocate along the first guide rod 13, and the movable tool holder 30 drives the turning tool 40 to move, thereby cutting the entire outer surface of the blank.

[0037] In another embodiment, the lathe body 10 further includes: a connecting plate 14, a slider 15, and a second guide rod 16. Both ends of the second guide rod 16 are fixedly connected to the frame 11, the axis of the second guide rod 16 is parallel to the axis of the first guide rod 13, the second guide rod 16 passes through the slider 15 and forms a sliding connection with the slider 15, the slider 15 is welded and fixed to one end of the connecting plate 14, the other end of the connecting plate 14 is welded and connected to the movable tool holder 30, and the illuminating lamp 60 is connected to the slider 15. When the movable tool holder 30 moves along the first guide rail, the connecting plate 14 drives the slider 15 to move synchronously along the second guide rod, thereby driving the illuminating lamp 60 installed on the slider 15 to move with the movable tool holder 30, so that the illuminating lamp 60 can follow the turning tool 40 to illuminate the cutting part of the blank.

[0038] Specifically, a clamp mounting hole 141 is formed on the connecting plate 14 for mounting a clamp. If the length of the blank is long, resulting in a large distance between the clamp 20 and the drill bit 50, the middle part of the blank is not supported and thus sags. When rotating at high speed, the middle part of the blank is prone to vibrate and thus damage the turning tool 40. By installing a clamp on the connecting plate 14, the middle part of the fastener can be supported to prevent the middle part of the blank from sagging.

[0039] Specifically, it also includes: a cleaning block 70. The cleaning block 70 is a sponge block, and multiple groups of cleaning blocks 70 are provided. The multiple groups of cleaning blocks 70 are respectively fixed to the movable tool holder 30 and the connecting plate 14 by bolts, and the lower end of the cleaning block 70 is in contact with the guide plane. When the turning tool 40 cuts the blank and the drill bit 50 drills the blank, the waste chips generated will fall on the guide plane. If the waste chips enter between the guide plane and the contact plane of the movable tool holder 30, the waste chips will lift the movable tool holder 30 and cause the movable tool holder 30 to vibrate. After the cleaning block 70 is provided, when the movable tool holder 30 moves along the first guide rod 13, the cleaning block 70 will push the waste chips on the guide plane to prevent the waste chips from contacting the contact plane of the movable tool holder 30, thereby preventing the waste chips from entering between the movable tool holder 30 and the guide plane.

[0040] Specifically, the frame 11 forms a material-dropping groove, which is formed in the middle of the guide plane. The surface of the cleaning block 70 that is toward the moving direction of the movable tool holder 30 is inclined toward the material-dropping groove. When the cleaning block 70 pushes the waste chips, the waste chips will fall into the material-dropping groove along the surface of the cleaning block 70 that is toward the moving direction of the movable tool holder 30, thereby preventing the waste chips from accumulating on the guide plane.

[0041] Specifically, it also includes: a waste tray 80. The waste tray 80 is placed below the material dropping channel to collect waste chips dropped from the material dropping channel.

[0042] Specifically, the lighting lamp 60 includes: a lamp head 61 and a connecting rod 62. One end of the connecting rod 62 forms a bowl-shaped joint groove, and the other end of the connecting rod 62 forms a ball head. The connecting rod 62 is provided in multiple groups, and in this embodiment, there are three groups. The bowl-shaped joint grooves of the three groups of connecting rods 62 are sleeved with the ball heads, so that the adjacent connecting rods 62 can be rotated to any angle. The ball head of the connecting rod 62 at one end is rotatably connected to the slider 15, and the connecting rod 62 at the other end is fixedly connected to the lamp head 61. The lamp head 61 is used to emit light for illumination. The worker rotates the three groups of connecting rods 62, so as to fine-tune the lamp head 61 to the top of the turning tool 40 to illuminate the cutting part of the blank.
