Description

Technical Field

[0001] The utility model relates to the technical field of motor shaft processing, in particular to an automatic feeding and discharging device for motor shafts based on a manipulator. Background Art

[0002] The motor shaft is a shaft used to connect a rotating device and is an important component of the motor. Usually, the motor shaft is made of iron, steel, stainless steel and other materials. Its diameter and length depend on the size and type of the motor used. The function of the motor shaft is to transmit the rotational power of the motor to other rotating equipment. When the motor rotates, the motor shaft transmits the power to the transmission device or rotating equipment to start rotating. The motor shaft usually needs to be polished on a lathe to keep the surface of the motor shaft smooth and ensure the flatness of the motor shaft surface.

[0003] At present, the existing motor shaft processing method is usually: the staff places the motor shaft sleeve in the chuck on the lathe, starts the chuck, clamps and fixes the motor shaft, and then starts the lathe to turn the motor shaft. After the motor shaft turning is completed, the staff takes out the processed motor shaft.

[0004] In the above scheme, the prior art requires the staff to manually complete the feeding and unloading operations of the motor shaft, and the work efficiency is low. Utility Model Content

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and provide an automatic feeding and unloading device for a motor shaft based on a manipulator. By providing a manipulator and a pneumatic clamp, the feeding and unloading work of the motor shaft can be automatically completed, thereby solving the problem that the prior art requires staff to manually complete the feeding and unloading work of the motor shaft, thereby improving work efficiency.

[0006] The solution of the utility model to solve the technical problem is:

[0007] A motor shaft automatic feeding and discharging device based on a manipulator includes a CNC lathe, a manipulator and a support frame. Two pneumatic clamps are symmetrically fixed to the end of the manipulator. A conveying mechanism is provided in the support frame. The conveying mechanism includes a conveying component and an abutment component. A clamping component is provided on the conveying component. An induction component is provided at the upper end of the support frame. The induction component is located at the output end of the conveying component. A collecting component is provided on one side of the CNC lathe.

[0008] When the motor shaft needs to be processed, multiple motor shaft sleeves are placed in the clamping component, and the transmission component is started, so that multiple motor shafts can be driven for transmission. When the sensing component senses the presence of the motor shaft, the transmission component is controlled to stop working, the manipulator is started, and the pneumatic clamp is driven to move, and one of the motor shafts is clamped and fixed by one of the pneumatic clamps, and then the pneumatic clamp is driven by the manipulator to move to the CNC lathe, and the motor shaft that has been turned is taken out by another pneumatic clamp, and then the motor shaft sleeve clamped and fixed on one of the pneumatic clamps is placed on the CNC lathe. The motor shaft is clamped and fixed by the chuck in the lathe, and the CNC lathe is started so that the motor shaft can be turned. At the same time, the motor shaft that has been turned is driven by the manipulator to move to the collection component so that the motor shaft that has been turned can be collected, thereby automatically completing the feeding and unloading operations of the motor shaft. The pneumatic clamp is driven by the manipulator to move to the required position, and the motor shaft is clamped and fixed by the pneumatic clamp. After waiting for the turning of the motor shaft in the CNC lathe to be completed, the above operation is repeated, so that the motor shaft can be turned continuously.

[0009] By providing a manipulator and a pneumatic clamp, the feeding and unloading of the motor shaft can be automatically completed, which solves the problem that the prior art requires workers to manually complete the feeding and unloading of the motor shaft, thereby improving work efficiency.

[0011] Through the above technical scheme, the conveyor belt is divided into an inclined surface and a horizontal surface. When the motor shaft sleeve needs to be placed in the clamping assembly, the conveyor belt is provided with an inclined surface, so as to facilitate the placement of the motor shaft sleeve in the clamping assembly. After placing multiple motor shaft sleeves in the clamping assembly, the motor is started, and one of the rollers is driven to rotate by the motor. The rotation of the roller can drive the conveyor belt to rotate, thereby driving the motor shaft on the inclined surface to be transported to the horizontal surface, so that the pneumatic clamp can clamp and fix the motor shaft.

[0012] The utility model is further configured as follows: the abutment assembly includes a connecting shaft rotatably connected in the support frame, a pressing wheel is fixed to the middle of the connecting shaft, and the pressing wheel abuts against the side wall of the conveyor belt.

[0013] Through the above technical solution, by providing a pressing wheel, the inner side wall of the conveyor belt can be pressed against the roller in the middle, thereby reducing the space occupied by the conveyor belt.

[0015] Through the above technical solution, when the motor shaft needs to be driven by the conveyor belt for transportation, the motor shaft sleeve is placed in the clamping block, so that the motor shaft can be driven by the conveyor belt for transportation.

[0016] The utility model is further configured as follows: the sensing component includes a first proximity sensor fixed on the upper end of the support frame, the first proximity sensor is located at the output end of the transmission component, the first proximity sensor is electrically connected to the controller, and the controller is electrically connected to the motor.

[0017] Through the above technical solution, by providing a first proximity sensor, when the first proximity sensor senses the presence of a motor shaft, the controller controls the motor to stop working, so that the motor shaft is fixed in the desired position, thereby facilitating the manipulator to drive the pneumatic clamp to clamp and fix the motor shaft.

[0018] The utility model is further configured as follows: the collecting component includes a bracket arranged on one side of the CNC lathe, and a collecting frame is placed on the upper end of the bracket.

[0019] Through the above technical solution, the motor shaft that has been turned can be driven by the manipulator to move into the collection frame, so that the motor shaft that has been turned can be collected.

[0020] The utility model is further configured as follows: a second proximity sensor is fixed to the upper end of the support frame, the second proximity sensor is located at the output end of the transmission component, the second proximity sensor is electrically connected to the controller, and the controller controls the manipulator.

[0021] Through the above technical solution, after the manipulator drives the pneumatic gripper to complete the action of removing the motor shaft, the manipulator drives the pneumatic gripper to move to the required position, and the pneumatic gripper is sensed by the second proximity sensor to determine whether the pneumatic gripper has removed the motor shaft, thereby preventing invalid operation.

[0022] The utility model is further configured as follows: two CNC lathes are provided.

[0023] Through the above technical solution, when one of the CNC lathes is turning the motor shaft, the motor shaft can be driven by the manipulator to move to another CNC lathe for turning, thereby improving the turning efficiency of the motor shaft.

[0024] The beneficial effects of the utility model are:
