[0029] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Example

[0031] The present invention will now be further described with reference to the accompanying drawings.

[0032] like Figures 1 to 5 As shown, this embodiment provides a high-precision automatic lathe, including a bed 10, and further including: a spindle unit 11, a longitudinal feed unit 12 and a loading unit 13 mounted on the bed 10. The spindle unit 11 and the loading unit 13 are distributed opposite to each other. A pneumatic chuck 14 for clamping workpieces is mounted on the spindle unit 11. A transverse feed tool post 15 is mounted on the longitudinal feed unit 12. A unloading robot 16 is located near the side of the bed 10. The loading unit 13 includes a vibratory feeder 24, a linear feed rail 25 located at the discharge end of the vibratory feeder 24, a screw sorting assembly 26 located at the discharge end of the linear feed rail 25, and a clamping assembly 44 for feeding.

[0033] The working principle and beneficial effects of the above technical solution are as follows:

[0034] This utility model discloses a high-precision automatic lathe. Screws are arranged via a vibratory feeder 24 and fed into a linear feed track 25, one by one, until they are positioned near the clamping assembly 44. The clamping assembly 44 then feeds the screws into a pneumatic chuck 14. After the pneumatic chuck 14 clamps the screws, the longitudinal feed unit 12 operates, driving the transverse feed tool holder 15 located thereon to move towards the spindle unit 11. The transverse feed tool holder 15 rests against the surface of the workpiece. The spindle unit 11 then operates, rotating the pneumatic chuck 14 and the screws mounted on it to complete the turning process. After turning, the unloading robot 16 removes the screws. This utility model provides a high-precision automatic lathe suitable for batch processing of small objects such as screws.

[0035] In one embodiment, screw sorting assembly 26 includes:

[0036] The tilting cylinder 17 is mounted on the top of the bed 10 via a support frame;

[0037] The sorting seat 27 is installed at the output end of the tilting cylinder 17 and is located near the discharge end of the linear feeding track 25.

[0038] The sorting chamber 28 is located at the top of the sorting seat 27. The screws delivered from the discharge end of the linear feeding track 25 fall into the sorting chamber 28.

[0039] The working principle and beneficial effects of the above technical solution are as follows:

[0040] Screws fall one by one into the sorting chamber 28. Based on the position of the screws at the beginning and end within the chamber 28, the rotating cylinder 17 operates, causing the sorting seat 27 to rotate 180°, thus ensuring that the beginning and end positions of the screws are consistent. This facilitates clamping by the clamping assembly 44.

[0041] In one embodiment, a detection block assembly and a pneumatic telescopic rod 29 are distributed opposite to each other in the sorting chamber 28. The detection block assembly includes a detection plate 30 and two sets of detection blocks 31 symmetrically installed on its front side. A gap 32 is left between the two sets of detection blocks 31 for the tail of a screw to enter. An arc-shaped fixing frame 33 is installed on the back side of the detection plate 30. One end of the detection rod 34 extends into the arc-shaped fixing frame 33. A position sensor 35 is installed on one end of the detection rod 34. The other end of the detection rod 34 is connected to a vertical mounting frame 36. The vertical mounting frame 36 is installed on the top of the sorting seat 27. A return spring 37 is sleeved on the detection rod 34 and abuts against the vertical mounting frame 36 and the arc-shaped fixing frame 33.

[0042] The working principle and beneficial effects of the above technical solution are as follows:

[0043] After the screw falls into the sorting chamber 28, the pneumatic telescopic rod 29 operates, thereby pushing the screw located in the sorting chamber 28, such as... Figure 5 As shown, if the tail of the screw is close to the detection plate 30, when the pneumatic telescopic rod 29 pushes the screw, the tail of the screw extends into the gap 32 between the two sets of detection blocks 31, thus preventing the detection plate 30 from moving. However, when the head of the screw is close to the detection plate 30, when the pneumatic telescopic rod 29 pushes the screw, the head of the screw cannot extend into the gap 32 between the two sets of detection blocks 31. The head of the screw abuts against the detection block 31, thereby driving the detection plate 30 connected to the detection block 31 and the bow-shaped fixing bracket 33 installed on the back of the detection plate 30 to move on the detection rod 34. The reset spring 37 is compressed by force, and the position sensor 35 installed on the detection rod 34 abuts against the back of the detection plate 31. The position sensor 35 sends a working signal to the flip cylinder 17, and the flip cylinder 17 rotates 180°, thereby keeping the head and tail of the screw in the same position.

[0044] In one embodiment, the sorting chamber 28 is surrounded by a detection plate 30, two sets of opposing side baffles 38, and a top plate 39. The side baffles 38 are installed on the top of the sorting seat 27, and the top plate 39 is installed at the output end of the pneumatic telescopic rod 29.

[0045] The working principle and beneficial effects of the above technical solution are as follows:

[0046] The top plate 39 is designed to facilitate the pneumatic telescopic rod 29 to push the screw. The sorting chamber 28 is surrounded by the detection plate 30, two sets of opposing side baffles 38 and the top plate 39, which facilitates the clamping assembly 44 to clamp the screw.

[0047] In one embodiment, each set of side baffles 38 consists of two side baffles, with space reserved between the two side baffles for the clamping assembly 44 to clamp the screws.

[0048] In one embodiment, the clamping component 44 includes:

[0049] Linear module 40, which is mounted on the top of the bed 10;

[0050] Longitudinal telescopic frame 41 is installed at the output end of linear module 40;

[0051] A transverse telescopic frame 42 is installed at the output end of the longitudinal telescopic frame 41.

[0052] Pneumatic gripper 43 is installed at the output end of the transverse telescopic frame 42 and is used to grip screws.

[0053] The working principle and beneficial effects of the above technical solution are as follows:

[0054] The linear module 40 drives the pneumatic gripper 43 to move between the screw sorting component 26 and the pneumatic chuck 14. With the cooperation of the longitudinal telescopic frame 41 and the transverse telescopic frame 42, the pneumatic gripper 43 can grasp the screw.

[0055] In one embodiment, the spindle unit 11 includes an electric spindle 18 and a spindle mounting base 19. The spindle mounting base 19 is mounted on the top of the bed 10, the electric spindle 18 is mounted inside the spindle mounting base 19, and the pneumatic chuck 14 is mounted on the output end of the electric spindle 18.

[0056] The working principle and beneficial effects of the above technical solution are as follows:

[0057] The electric spindle 18, mounted on the spindle mounting base 19, operates, thereby driving the pneumatic chuck 14 mounted on the output end of the electric spindle 18 and the screw located on the pneumatic chuck 14 to rotate at high speed to complete the cutting operation.

[0058] In one embodiment, the longitudinal feed unit 12 includes: a linear guide 20, a longitudinal feed seat 21, a ball screw 22, and a servo motor 23. The linear guide 20 is mounted on the top of the bed 10, the longitudinal feed seat 21 is slidably mounted on the linear guide 20, the transverse feed tool post 15 is mounted on the longitudinal feed seat 21, the ball screw 22 is located at the side end of the bed 10, the bottom end of the longitudinal feed seat 21 is sleeved on the ball screw 22, and the servo motor 23 is mounted at the side end of the bed 10. The output end of the servo motor 23 is connected to one end of the ball screw 22 through a gearbox.

[0059] The working principle of the above technical solution is as follows:

[0060] The servo motor 23 installed on the side of the bed 10 works, thereby driving the ball screw 22 installed on the output end of the servo motor 23 to rotate. The longitudinal feed seat 21 sleeved on the ball screw 22 slides along the linear guide rail 20, thereby realizing the left and right lateral movement of the transverse feed tool holder 15 installed on the longitudinal feed seat 21.

[0061] In one embodiment, a protective cover is installed at the top of the bed 10.

[0062] The beneficial effects of the above technical solution are as follows:

[0063] The protective casing serves a protective function.

[0064] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
