Description

Technical Field

[0001] The present invention relates to the technical field of cutting devices, and in particular to a shell cutting device for permanent magnet motor production. Background Art

[0002] With the continuous improvement of permanent magnet material performance and the development of motor technology, permanent magnet motors have been widely used in various fields of the national economy. Permanent magnet motor housings are needed in permanent magnet motors to protect them and increase their lifespan. In order to facilitate the installation of the permanent magnet motor, the housing needs to be cut.

[0003] The motor housing metal production cutter currently used has a simple structure and is usually manually supported by a person to expose the housing directly to the air for cutting. The debris generated during the cutting process will fly everywhere. Since the human body is too close to the cutting position, the flying debris can easily cause harm to the human body. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention provides a shell cutting device for permanent magnet motor production, which overcomes the shortcomings of the prior art and effectively solves the problem that in the prior art, the shell is manually supported and directly exposed to the air for cutting, and the debris generated during the cutting process will fly everywhere. Since the human body is too close to the cutting position, the flying debris can easily cause harm to the human body.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A shell cutting device for permanent magnet motor production comprises a bed, a shell is fixed on the top of the bed, and a cutting mechanism is fixed on the top inner wall of the shell, a conveying mechanism is arranged below the cutting mechanism, and guide mechanisms are arranged on both sides of the conveying mechanism, the cutting mechanism comprises a mounting plate, a push rod motor fixed to one end of the bottom of the mounting plate, a cutter fixed to the bottom end of the push rod motor, and an infrared sensor mounted on the other end of the bottom of the mounting plate, the conveying mechanism comprises symmetrically distributed support plates, rollers rotatably connected between two support plates at equal distances, and a conveyor belt transmission-connected to the two ends of the outer wall of the roller, the guide mechanism comprises a fixed frame, guide rollers rotatably connected in the fixed frame at equal distances, a connecting plate fixed to the bottom of the outer wall of one side of the fixed frame, a movable block fixed to the bottom end of the connecting plate, a screw rotatably connected to the top of the fixed frame, fixed rods fixed to the two ends of the top of the fixed frame, a fixed plate fixed to the tops of the two fixed rods, and a connecting shell arranged on one side of the fixed frame.

[0007] The first servo motor drives one of the bidirectional screws to rotate, and the rotating bidirectional screw drives the other bidirectional screw to rotate through the transmission connected pulley, and the rotating bidirectional screw drives the two screwed movable blocks to approach or move away from each other, so that the distance between the two guide mechanisms is adapted to the specifications of the shell, and the shell is placed on two conveyor belts, and the conveyor belts drive the shell to be transported into the outer shell. After the infrared sensor detects the shell below, the second servo motor drives the screw to rotate, and the rotating screw passes through the screwed first connecting block, cooperates with the second connecting block and the fixed rod to slide, so that the connecting shell moves downward to the shell, and the pressure wheel abuts against the top of the shell, and while pressing the shell down and fixing it, it can cooperate with the conveyor belt to transport the shell, and at the same time, the push rod motor extends downward to drive the cutter to approach the shell for cutting.

[0008] Preferably, a controller is installed on one side outer wall of the housing, and the first servo motor, the cutter, the infrared sensor, the drive motor and the second servo motor are all electrically connected to the controller.

[0009] The shell is used to shield and protect the debris generated by cutting, and the controller controls the first servo motor, the cutter, the infrared sensor, the drive motor and the second servo motor.

[0010] Preferably, grooves are provided on both sides of the top of the bed, and bidirectional screw rods are rotatably connected in the grooves.

[0011] Two bidirectional screw rods are installed on both sides of the bed body through grooves.

[0012] Preferably, one end of one of the bidirectional screw rods is connected to a first servo motor, and the other ends of the two bidirectional screw rods are both sleeved and fixed with pulleys, and the two pulleys are connected by belt transmission.

[0013] The first servo motor drives one of the bidirectional screws to rotate, and the rotating bidirectional screw drives the other bidirectional screw to rotate via a belt pulley connected by transmission.

[0014] Preferably, a driving motor is installed on one end of an outer wall of one side of one of the support plates, and an output shaft of the driving motor is connected and fixed to one of the rollers.

[0015] A driving motor drives one of the rollers to rotate, so that the two conveyor belts are transported on the rollers.

[0016] Preferably, a gap is left between the two conveyor belts, and the gap is located directly below the cutter.

[0017] The gap between the two conveyor belts can accommodate the cutter to perform cutting operations downward, thereby preventing the cutter from damaging the conveyor belts.

[0018] Preferably, a screw hole adapted to the bidirectional screw rod is provided on an outer wall of one side of the movable block, and the movable block forms a sliding fit with the groove.

[0019] The rotating bidirectional screw drives the two screw-connected movable blocks to move closer to or farther from each other.

[0020] Preferably, the bottom of the connecting shell is rotatably connected to pressure wheels distributed at equal distances, and a first connecting block threadedly connected to the screw rod is fixed to the outer wall of one side of the connecting shell, and second connecting blocks movably connected to the fixing rod are fixed to both ends of the outer wall of one side of the connecting shell.

[0021] The rotating screw rod cooperates with the plug-in sliding of the second connecting block and the fixing rod through the threaded first connecting block, so that the connecting shell moves downward close to the shell body, and the pressure wheel abuts against the top of the shell body, pressing down and fixing the shell body, and can cooperate with the conveyor belt to transport the shell body.

[0022] The beneficial effects of the present invention are:

[0023] By placing the shell on two conveyor belts, the conveyor belts drive the shell to be transported into the outer shell. After the infrared sensor detects the shell below, the second servo motor drives the connecting shell downward to the shell, and the pressure wheel abuts against the top of the shell. While pressing the shell down and fixing it, it can cooperate with the conveyor belt to transport the shell. At the same time, the push rod motor extends downward to drive the cutter to approach the shell for cutting operations. This effectively solves the problem in the prior art that the shell is manually supported and directly exposed to the air for cutting operations, and the debris generated during the cutting process will fly everywhere. Since the human body is too close to the cutting position, the debris flying everywhere can easily cause harm to the human body. BRIEF DESCRIPTION OF THE DRAWINGS
