Description

Technical Field

[0001] The utility model relates to the field of material processing, in particular to a bar stock blanking mechanism for a centerless lathe. Background Art

[0002] A bar stock blanking mechanism for a centerless lathe is mainly used to orderly and accurately convey the bar stock to be processed to the turning processing area at a certain rhythm and accuracy during the processing of the centerless lathe, push the bar stock along the guiding device to the specified processing position, and ensure the position accuracy through the positioning device to prepare for the subsequent centerless lathe processing. There are some disadvantages in the existing bar stock blanking mechanism. First of all, the traditional blanking method often relies on manual operation, which is not only inefficient, but also difficult to ensure the accuracy and consistency of blanking, easily causing material waste and unstable processing quality. Secondly, the simple blanking device has a simple structure and single function, and cannot adapt to complex processing processes and diverse bar stock specifications, with poor adaptability and inability to flexibly adapt to bar stocks of different specifications. To solve the above problems, we propose a bar stock blanking mechanism for a centerless lathe. Summary of the Invention

Through the left and right movement of the third support plate, the bar stock is driven to move, adapting to complex processing techniques and diverse bar stock specifications, and being able to flexibly adapt to bar stocks of different specifications. When the bar stock runs to the upper end of the loading mechanism, the air pump operates to drive the conveying plate and the third support plate to descend, causing the bar stock to fall onto the upper end of the loading mechanism. Since the upper end of the loading mechanism is inclined, the bar stocks are automatically stacked, reducing the manual labor intensity, ensuring operation safety, avoiding accidental injuries that may occur during the manual cutting process of workers, and improving production safety.

The second V-shaped support frame 21 is rotatably connected with the second support plate 17. The second support plate 17 is rotatably connected with a linking rod 27. The linking rod 27 is fixedly connected with the second V-shaped support frame 21. The other end of the second V-shaped support frame 21 is rotatably connected with a first push plate 22. A first push plate 22 is arranged at one end of the first push plate 22. A first support rod 24 is arranged on the side wall of the first push plate 22. A fixed plate 26 is arranged at the top end of the first support rod 24. A housing 46 is arranged at the top end of the fixed plate 26.

[0027] Specifically, the operation of the air pump 13 drives the push shaft 14 to move, drives the rotating plate 16 to rotate by driving the first push block 15, thereby driving the first V-shaped support frame 18 to rotate. One end of the first V-shaped support frame 18 drives the second push plate 23 to push the conveying plate 47 upward, and at the same time, the other end of the first V-shaped support frame 18 drives the second V-shaped support frame 21 to rotate. The other end of the second V-shaped support frame 21 drives the first push plate 22 to move, so that the first support rod 24 moves upward. By the operation of the two groups of air pumps 13, the lifting of the conveying plate 47 and the third support plate 52 is controlled.

[0028] In this embodiment, a hole is formed in the side wall of the housing 46 and a rotating rod 43 is rotatably connected. A third gear 42 is arranged on the side wall of the rotating rod 43.

The rotating shaft 51 is in transmission connection with the fourth gear 44.

[0031] Specifically, the two groups of fourth gears 44 drive the two groups of rotating shafts 51 to rotate, so that the sliding plate 5 drives the third support plate 52 to move left and right in the groove formed at the top end of the conveying plate 47. The buffer pad 53 arranged at the top end of the third support plate 52 protects the bar stock.

[0032] In this embodiment, the bottom end of the conveying plate 47 is fixedly connected to the second push plate 23. A fixing plate 26 is arranged at the bottom end of the housing 46.

[0033] Specifically, the left and right movement of the third support plate 52 drives the bar stock above the buffer pad 53 to move. When the bar stock runs to the upper end of the loading mechanism 7, the operation of the air pump 13 drives the conveying plate 47 and the third support plate 52 to descend, so that the bar stock falls on the upper end of the loading mechanism 7. Since the upper end of the loading mechanism 7 is inclined, the bar stock is automatically stacked.

A lifting mechanism 6 is provided at the bottom end of the first motor 3. A first rotating shaft 32 is provided at one end of the first motor 3. The first rotating shaft 32 is rotatably connected to a transmission sleeve 33. A plurality of groups of second rotating shafts 34 are provided on the side wall of the transmission sleeve 33.

[0035] Specifically, the operation of the first motor 3 drives the first rotating shaft 32 to rotate. Through the transmission connection between the first rotating shaft 32 and the second rotating shaft 34, the first gear 35 rotates. Through the operation of the lifting mechanism 6, the mounting plate 31 moves up and down, and at the same time drives the conveying wheel 36 to move up and down.

[0036] In this embodiment, a first gear 35 is provided on the side wall of the second rotating shaft 34. A plurality of groups of first gears 35 are in transmission connection. A conveying wheel 36 is provided at one end of the second rotating shaft 34. A support plate 37 is provided at the top end of the mounting plate 31.

[0038] It should be noted that the present utility model is a bar stock blanking mechanism for a centerless lathe. The user drives the first rotating shaft 32 to rotate by the operation of the first motor 3. Since the first rotating shaft 32 is in transmission connection with the second rotating shaft 34, the first gear 35 rotates. The conveying wheel 36 is fixed by the fixed bracket 38. Through the rotation of several groups of the first gears 35, the conveying wheel 36 rotates, and the bar stock is conveyed by the rotation of the conveying wheel 36. When the bar stock is completely above the conveying wheel 36, the air pump 13 operates to push the push shaft 14 to move, drive the rotating plate 16 to rotate by driving the first push block 15, thereby driving the first V-shaped support frame 18 to rotate. One end of the first V-shaped support frame 18 drives the second push plate 23 to push the conveying plate 47 to move upward. At the same time, the other end of the first V-shaped support frame 18 pushes the second V-shaped support frame 21 to rotate, and the other end of the second V-shaped support frame 21 drives the first push plate 22 to move, so that the first support rod 24 moves upward. By the operation of two groups of air pumps 13, the lifting of the conveying plate 47 and the third support plate 52 is controlled. The operating lifting mechanism 6 drives the mounting plate 31 to move up and down, and at the same time drives the conveying wheel 36 to move up and down, so as to lift the bar stock by the third support plate 52. The second motor 4 operates to drive the second gear 41 to rotate, thereby driving the third gear 42 and the rotating rod 43 to rotate. The rotation of the rotating rod 43 drives the fourth gear 44 to rotate. Two groups of the fourth gears 44 drive two groups of rotating shafts 51 to rotate, so that the sliding plate 5 drives the third support plate 52 to move left and right in the groove provided at the top end of the conveying plate 47. The bar stock is protected by the buffer pad 53 provided at the top end of the third support plate 52. The left and right movement of the third support plate 52 drives the bar stock on the upper end of the buffer pad 53 to move. When the bar stock runs to the upper end of the bearing mechanism 7, the air pump 13 operates to drive the conveying plate 47 and the third support plate 52 to descend, so that the bar stock falls on the upper end of the bearing mechanism 7. Since the upper end of the bearing mechanism 7 is inclined, the bar stock is automatically stacked.
