Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology, and specifically relates to a spinning machine. Background Technology

[0002] Spinning machines are used in the cookware industry for forming pot bodies from round pieces. For example, Chinese patent literature discloses a spinning machine for processing multi-curvature pot bodies [Application No.: 202321080075.6; Authorization Announcement No.: CN220028485U], which includes a worktable, a main shaft rotatably connected to the worktable, a drive device for driving the main shaft to rotate on the worktable, a rotating platform and a pot blank connected to the rotating platform on the main shaft, a steel plate clamping mechanism on the worktable, and a positioning plate. The worktable also includes an X-axis moving device for driving the positioning plate and a Z-axis moving device for adjusting the height of the positioning plate. A [missing information - likely a component or mechanism] is rotatably connected to the positioning plate. The mounting base has a first motor fixedly connected to the positioning plate. The output shaft of the first motor is horizontally or diagonally positioned and used to drive the mounting base to rotate. A spinning wheel is rotatably connected to the mounting base. An abutment block is provided on the positioning plate, and an arc-shaped surface is provided on the abutment block. A roller is rotatably mounted on the mounting base, and the roller abuts against the arc-shaped surface. The steel plate pressing mechanism includes a fixed column and a movable plate. The movable plate and the fixed column are respectively provided with a first connecting hole and a second connecting hole for fastener connection. A horizontal plate is fixedly mounted on the movable plate, and a rotating shaft is rotatably connected to the horizontal plate. A stop block is provided on the rotating shaft located below the horizontal plate, and a pressure plate is connected to the lower end of the rotating shaft.

[0003] The aforementioned spinning machine for processing multi-curvature pot bodies increases the rotational freedom of the spinning wheel, allowing the angle of the spinning wheel to be adjusted, which is beneficial for the production of multi-curvature pot bodies. However, the steel plate clamping mechanism needs to be set on the worktable, which requires a large support area of ​​the worktable. This makes the structure less compact and increases the overall volume of the spinning machine. Moreover, the machining accuracy requirements for the abutment block and the arc surface are high, otherwise it will affect the curvature of the pot body. The arc surface also limits the rotation range of the mounting base, that is, it limits the extreme curvature of the pot body, resulting in poor adaptability. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a spinning machine with a compact structure and good adaptability.

[0005] The objective of this utility model can be achieved through the following technical solution: A spinning machine includes a worktable, a mounting base fixedly connected to the worktable, a vertically displaceable slide plate one on the mounting base, a horizontally displaceable slide plate two on the slide plate one, a reduction motor fixedly connected to the slide plate two, a rotating seat fixedly connected to the output end of the reduction motor, and a spinning wheel on the rotating seat.

A protruding cylindrical roller bearing is provided at the end face of the rotating seat away from the spinning wheel, and the slide plate two has a flat surface for the cylindrical roller bearing to abut against.

[0006] In the aforementioned spinning machine, the guiding structure includes a guide sleeve and a guide post. The guide sleeve is vertically inserted into the mounting beam, and the guide post axially passes through the guide sleeve, with its lower end fixedly connected to the mounting plate.

[0007] In another scenario, in one of the aforementioned spinning machines, the guiding structure includes a slide rail vertically fixed to a mounting beam, and a slider fixed to the slide rail on a mounting plate. The slider and slide rail work together to guide the piston rod of the cylinder, preventing it from wobbling and ensuring good operational stability.

[0008] In the aforementioned spinning machine, the adapter seat is equipped with a deep groove ball bearing and a tapered roller bearing. The deep groove ball bearing is located above the tapered roller bearing, and a spacer is provided between the two.

[0021] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, this spinning machine includes a worktable 1, a mounting base 2 fixedly connected to the worktable 1, a vertically displaceable slide plate 3 on the mounting base 2, a horizontally displaceable slide plate 4 on the slide plate 3, a reduction motor 5 fixedly connected to the slide plate 4, a rotating seat 6 fixedly connected to the output end of the reduction motor 5, a spinning wheel 7 on the rotating seat 6, a longitudinally arranged mounting beam 8 protruding from the side of the rotating seat 6 fixedly connected to the top of the mounting base 2, a cylinder 9 fixedly connected to the mounting beam 8, a mounting plate 10 fixedly connected to the piston rod of the cylinder 9 vertically downward, a transition seat 11 fixedly connected to the bottom of the mounting plate 10, a rotating shaft 12 connected to the transition seat 11, a pressure plate 13 connected to the lower end of the rotating shaft 12, a guide structure between the mounting beam 8 and the mounting plate 10 for guiding the piston rod of the cylinder 9, a protruding cylindrical roller bearing 14 on the end face of the rotating seat 6 away from the spinning wheel 7, and a flat surface 15 on the slide plate 4 for the cylindrical roller bearing 14 to abut against.

[0023] This spinning machine integrates a mounting beam 8 on the mounting base 2 of the worktable 1, resulting in a compact structure and small overall size. During operation, the piston rod of the cylinder 9 extends downward, driving the mounting plate 10 and the adapter 11 to descend together until the pressure plate 13 presses the workpiece tightly. During the spinning process, the rotating shaft 12 rotates relative to the adapter 11. The guiding structure not only ensures smooth extension and retraction of the piston rod of the cylinder 9 but also prevents the mounting plate 10 and the adapter 11 from shaking, ensuring operational stability. The cylindrical roller bearing 14 abuts against the plane 15 on the slide plate 2 4, supporting the rotating seat 6 and preventing the rotating seat 6 from loosening at the connection due to prolonged stress, thus ensuring operational stability. The cylindrical roller bearing 14 and the plane 15 cooperate without restricting the rotation range of the cylindrical roller bearing 14, thus eliminating the limitation of the previous arc-shaped surface on the extreme curvature of the pot body, resulting in good adaptability. The cylindrical roller bearing 14 has a large radial load capacity, can withstand heavy loads and impact loads, and has a long service life.

[0024] In further detail, the guide structure in this embodiment includes a guide sleeve 16 and a guide post 17. The guide sleeve 16 is vertically inserted into the mounting beam 8, and the guide post 17 axially passes through the guide sleeve 16, with its lower end fixedly connected to the mounting plate 10. The guide post 17 and the guide sleeve 16 cooperate to guide the piston rod of the cylinder 9, preventing wobbling and ensuring operational stability. In this embodiment, there are two guide sleeves 16 and two guide posts 17, with the piston rod of the cylinder 9 located between the two guide posts 17, resulting in good balance and stable operation. The lower end of the guide sleeve 16 is a flange, through which several screws pass and are fixedly connected to the mounting beam 8. The lower end of the guide post 17, protruding from the bottom surface of the mounting plate 10, also has a flange, through which several screws pass and are fixedly connected to the mounting plate 10, facilitating assembly.

[0025] The adapter 11 houses a deep groove ball bearing 18 and a tapered roller bearing 19. The deep groove ball bearing 18 is positioned above the tapered roller bearing 19, with a spacer 20 between them. The upper end of the rotating shaft 12 passes through the deep groove ball bearing 18 and the tapered roller bearing 19. The spacer 20 prevents interference between the deep groove ball bearing 18 and the tapered roller bearing 19. The tapered roller bearing 19 bears the combined radial and axial loads of the rotating shaft 12, has a high load-bearing capacity, and a low limiting speed. The deep groove ball bearing 18 has low frictional resistance and can withstand the combined loads of the rotating shaft 12. When the rotating shaft 12 drives the pressure plate 13 to press the workpiece, the deep groove ball bearing 18, in conjunction with the tapered roller bearing 19, restricts the axial displacement of the rotating shaft 12, ensuring smooth rotation of the rotating shaft 12 and guaranteeing operational stability.

[0026] A flat plate 21 is fixed to the slide plate 4 by screws. The flat surface 15 of the flat plate 21 is used for the cylindrical roller bearing 14 to abut against. The flat plate 21 is replaceable, reducing the cost of use. An insert 22 is embedded in the top of the rotating seat 6. The insert 22 is fixed to the rotating seat 6 by screws. A fastening pin 23 is inserted through the insert 22 with an interference fit. The cylindrical roller bearing 14 is located in the insert 22 and is provided for the fastening pin 23 to pass through. In this way, the cylindrical roller bearing 14 and the insert 22 are integrated together, which is convenient for installation, removal and replacement, easy to operate and has low operating costs.

[0027] The rotating base 6 is fixed to a right-angled connecting plate 24 by screws. A locking pin is inserted through the connecting plate 24 with an interference fit. A tapered needle roller bearing 25 is fitted on the locking pin. The spinning roller 7 is fitted with an interference fit on the outside of the tapered needle roller bearing 25. This makes installation and removal convenient, and the tapered needle roller bearing 25 has a good load-bearing capacity, ensuring the service life of the spinning roller 7.

[0028] The spinning roller 7 includes a mounting portion 71 and a spinning portion 72. The outer wall of the mounting portion 71 is cylindrical and is mounted on the outside of the tapered needle roller bearing 25. The outer wall of the spinning portion 72 is a ring of convex spherical surface. The mounting portion 71 facilitates the installation of the spinning roller 7 and avoids interference. The spherical surface ensures good load-bearing capacity of the spinning portion 72 and smooth spinning process.
