Description

Technical Field

[0001] This utility model relates to the field of rotor shaft processing technology, specifically a cutting device for rotor shaft processing with a protective structure. Background Technology

[0002] A rotor shaft is a forging with sufficient mechanical strength to withstand the torque transmitted from the prime mover and the huge electromagnetic torque of a sudden short circuit at the generator outlet, and with good magnetic permeability. It serves as the carrier of the generator's main magnetic poles.

[0003] When machining rotor shafts, a cutting device is needed to cut the rotor shafts. However, the rotor shafts are cut manually by workers, which can easily lead to accidental injury to workers during the manual feeding and cutting process, threatening their lives. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a cutting device for machining rotor shafts with a protective structure, which has advantages such as automatic feeding and cutting, and solves the problem that the cutting device does not have automatic feeding.

[0005] This utility model discloses a cutting device for machining rotor shafts with a protective structure, comprising a worktable. A cutting assembly is located on the right side of the top of the worktable, and a feeding assembly is located on the left side of the top of the worktable. The feeding assembly includes an L-plate, the bottom of which is fixedly connected to the worktable, and the right side of which is fixedly connected to the cutting assembly. A second motor is located on the top left side of the L-plate, and a screw is located at the output end of the second motor. A threaded sleeve is threaded onto the surface of the screw, and a fixing frame is fixedly connected to the bottom of the threaded sleeve. A fixing clamp is located within the inner cavity of the fixing frame. Springs are located at the connection points between the top two ends of the fixing clamp and the fixing frame. A pull ring is located at the top of the fixing clamp, and movable blocks are located at both ends of the fixing clamp. Movable grooves that match the movable blocks are opened at both ends of the inner cavity of the fixing frame. The bottom of the fixed frame is equipped with a slider, and the top of the worktable is provided with a groove that matches the slider. First, the pull ring is pulled, causing the fixed clamping plate to move upwards. The fixed clamping plate moves upwards in conjunction with the movable groove and movable block within the fixed frame. At this point, one end of the rotor shaft is positioned on the corresponding side of the fixed frame and the fixed clamping plate. Then, the pull ring is released, and the fixed clamping plate moves downwards due to the inertia of the spring. The fixed clamping plate and the fixed frame then fix one end of the rotor shaft. At this time, the second motor runs, driving the screw sleeve to move. The screw sleeve then drives the fixed frame to move, and the groove and slider on the worktable move in conjunction with the fixed frame. The fixed frame then drives the rotor shaft to move. When the rotor shaft reaches the desired cutting position, the cutting assembly cuts the rotor shaft.

[0006] This invention discloses a cutting device for machining rotor shafts with a protective structure. The cutting assembly includes a frame, the bottom of which is fixedly connected to a worktable. The left side of the frame is fixedly connected to an L-plate.

[0007] The present invention discloses a cutting device for processing rotor shafts with a protective structure, wherein a guide plate is provided on the right side of the top of the worktable and the guide plate is located on the left side of the cutting blade. Through the guide plate, when the rotor shaft is transported to the bottom of the cutting assembly by the feeding assembly for cutting, the guide plate can assist the rotor shaft in moving and prevent the rotor shaft from deviating from the predetermined cutting position during the conveying process.

[0008] The present invention relates to a cutting device for machining rotor shafts with a protective structure, wherein a movable plate is rotatably connected to the surface of the screw, and the top of the movable plate is fixedly connected to an L-plate. The movable plate can assist the screw in rotating, thus preventing the screw from jamming during rotation.

[0009] The present invention relates to a cutting device for machining rotor shafts with a protective structure, wherein the four corners of the bottom of the worktable are provided with support columns, and the bottom of the support columns is provided with anti-slip pads.

[0010] The present invention relates to a cutting device for processing rotor shafts with a protective structure, wherein the surface of the pull ring is provided with anti-slip particles, and the number of anti-slip particles is not less than fifty. The anti-slip particles can prevent the pull ring from slipping when it is pulled, thus preventing the pull ring from falling off when the user pulls it.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model first pulls the pull ring, which drives the fixed clamp plate to move upward. The fixed clamp plate moves upward through the movable groove and movable block in the fixed frame. At this time, one end of the rotor shaft is placed on the side of the fixed frame and the fixed clamp plate. Then, the pull ring is released, and the fixed clamp plate moves downward through the inertia of the spring. The fixed clamp plate and the fixed frame fix one end of the rotor shaft. At this time, the second motor runs, which drives the screw sleeve to move. The screw sleeve drives the fixed frame to move. The fixed frame moves through the sliding groove and slider on the worktable. The fixed frame drives the rotor shaft to move. When the rotor shaft moves to the required cutting position, the cutting component cuts the rotor shaft.

[0012] 2. When cutting is required, the electric push rod first runs, which drives the first motor to move. The first motor then drives the cutting blade to move. At this time, the first motor runs, which drives the cutting blade to rotate. The cutting blade can then cut the rotor shaft. The guide plate can assist the rotor shaft in moving when it is being transported by the feeding assembly to the bottom of the cutting assembly for cutting, thus preventing the rotor shaft from deviating from the predetermined cutting position during the conveying process. The movable plate can assist the screw in rotating, preventing it from jamming during rotation. The anti-slip particles prevent the pull ring from slipping when pulled, thus preventing it from falling off. Attached Figure Description
