Technical Field

[0001] The utility model relates to the technical field of coal mill frame production, in particular to a vertical lathe for coal mill frame production. Background Art

[0002] A vertical lathe is a machine tool mainly used for processing large and heavy workpieces and workpieces that are not easy to be clamped on a horizontal lathe. The spindle axis of the vertical lathe is perpendicular to the horizontal plane, and the workpiece is installed on a horizontal rotating worktable. The vertical lathe can process various cylindrical, conical or other rotating surfaces and can perform multi-functional processing such as turning, milling, boring and drilling. In the processing and production of coal mill frames, a vertical lathe is required for grooving.

[0003] The existing vertical lathe for coal mill frame production is not convenient for driving the coal mill frame clamped between U-shaped clamping plates to rotate to a set angle, and cannot achieve full grooving treatment of the coal mill frame. In the existing processing, the position of the coal mill frame needs to be changed, reducing the processing efficiency. Therefore, a vertical lathe for coal mill frame production is proposed, which can drive the coal mill frame clamped between U-shaped clamping plates to rotate to a set angle, achieve full grooving treatment of the coal mill frame, and does not need to change the position of the coal mill frame, greatly improving the processing efficiency. Summary of the Invention

[0004] Aiming at the problems in the prior art, the utility model provides a vertical lathe for coal mill frame production, which can drive the coal mill frame clamped between U-shaped clamping plates to rotate to a set angle, achieve full grooving treatment of the coal mill frame, and does not need to change the position of the coal mill frame, greatly improving the processing efficiency.

[0005] The technical solution adopted by the utility model to solve its technical problems is a vertical lathe for coal mill frame production, including a base, end plate A and end plate B. At both ends of the top of the base, end plate A and end plate B are respectively arranged, and end plate A is welded to the base. On end plate A and end plate B, a rotating shaft A and a rotating shaft B are respectively sleeved through bearings. Inside the rotating shaft A and the rotating shaft B, U-shaped clamping plates are welded, and at one end of the rotating shaft A, a driven bevel gear is sleeved. On one side of end plate A, a servo motor is installed through a mounting seat, and a driving bevel gear is sleeved on the output shaft of the servo motor;

[0006] On one side of the base, a back plate is welded, and at one side of the bottom end of the back plate, a forward and reverse motor is installed through a mounting seat. A lead screw is sleeved on the output shaft of the forward and reverse motor, and a lead screw block is sleeved on the lead screw. On one side of the lead screw block, an XY displacement platform is connected through a connecting frame. At the bottom driving end of the XY displacement platform, a driving motor is installed through a mounting seat. At the inner bottom end of end plate A, an electric cylinder is installed through a mounting seat, and the output shaft of the electric cylinder is connected to end plate B through a connecting disc.

[0007] By adopting the above technical solution, the rotation angle of the servo motor is automatically controlled by the servo motor controller. The servo motor drives the active bevel gear to rotate. Since the active bevel gear and the driven bevel gear mesh with each other, the coal mill frame clamped between the U-shaped clamping plates is driven to rotate to a set angle, realizing full slotting treatment of the coal mill frame without changing the position of the coal mill frame, greatly improving the processing efficiency.

[0008] Specifically, on one side of the end plate A and at one end of the servo motor, a servo motor controller is installed by screws. The output end of the servo motor controller and the input end of the servo motor are electrically connected through a wire.

[0009] By adopting the above technical solution, it is convenient to control the rotation angle of the servo motor by the servo motor controller, so as to rotate the clamped coal mill frame to a set angle for use.

[0010] Specifically, the top of the back plate is welded with a top plate, and the top end of the lead screw is connected to the top plate through a bearing.

[0011] Specifically, clamping bolts are installed on both sides of the U-shaped clamping plate through bolt holes.

[0012] Specifically, the active bevel gear and the driven bevel gear mesh with each other, and a cutter head is sleeved on the output shaft of the driving motor.

[0013] Specifically, a chute is opened on one side of the back plate and above the forward and reverse motor. A slide bar slides in the chute, and the slide bar is connected to the lead screw block.

[0014] By adopting the above technical solution, the lead screw block slides back and forth on the lead screw, improving the stability effect.

[0015] The beneficial effects of the present utility model:

[0016] For a vertical lathe for producing a coal mill frame of the present utility model, after connecting the power supply of the electric cylinder, the distance between the U-shaped clamping plates is adjusted according to the size of the coal mill frame. The two ends of the coal mill frame are clamped in the U-shaped clamping plates and the clamping bolts are tightened to achieve quick fixation. The XY displacement platform is used to drive the driving motor for precise positioning and the cutter head is aligned with the slotting position of the coal mill frame. The driving motor is turned on to drive the cutter head to rotate quickly, and the power supply of the forward and reverse motor is connected. The forward and reverse motor drives the lead screw to rotate, thereby driving the lead screw block to slide downward on the lead screw, driving the cutter head of the driving motor to move downward, and performing slotting processing on the coal mill frame.

[0017] A vertical lathe for producing a coal mill frame according to the present utility model uses a servo motor controller to automatically control the rotation angle of the servo motor, and uses the servo motor to drive the rotation of the active bevel gear. Since the active bevel gear and the driven bevel gear mesh with each other, the coal mill frame clamped between the U-shaped clamping plates is driven to rotate to a set angle, realizing a full slotting process for the coal mill frame without changing the position of the coal mill frame, greatly improving the processing efficiency.

[0026] When in use, the servo motor controller 1 is used to automatically control the rotation angle of the servo motor 2, and the servo motor 2 is used to drive the active bevel gear 3 to rotate. Since the active bevel gear 3 and the driven bevel gear 4 are meshed with each other, the coal mill frame clamped between the U-shaped clamping plates 14 is driven to rotate to a set angle, thereby achieving comprehensive grooving of the coal mill frame without changing the position of the coal mill frame, thereby greatly improving the processing efficiency.
