Mechanical deburring device

Abstract

The invention belongs to the field of machining operation and particularly relates to a mechanical deburring device arranged at the tail end of a mechanical arm. The mechanical deburring device comprises a motor, a magnetic buffer, a rotating shaft, a tool bit and a casing, wherein the motor is arranged in the casing, and the magnetic buffer is located on the outer side of the casing and fixedly connected with the casing. One end of the motor is connected with a universal joint which is fixedly connected with the casing, an output shaft of the motor is fixedly connected with the rotating shaft which penetrates through the magnetic buffer and is connected with the tool bit through a torque limited coupler, and one end of the rotating shaft close to the motor is provided with a gravity center adjusting part. The mechanical deburring device is directly driven by the motor, does not need an air compressor for switching, reduces power cost and device cost, improves resource use efficiency, is small in noise after being driven, achieves intelligentized buffer due to the fact that the magnetic buffer is used for buffering and the buffering effect can be adjusted at any time, and is good in deburring effect.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and in particular relates to a mechanical deburring device arranged at the end of a manipulator. Background technique [0002] Existing mechanical deburring devices are generally aimed at special parts. Manipulator-assisted machining deburring is an important part of advanced manufacturing technology, which can be suitable for deburring of various parts. However, most robots are position-controlled and have High position control accuracy and repetition accuracy, while most of the manipulators are in series structure, and their rigidity is low. Therefore, if there is a large part error or assembly error, such as a large error, the manipulator, tool or parts will be Therefore, the deburring device installed at the end of the manipulator is required to have a certain degree of compliance and tolerate the existence of errors to a certain extent. The existing manipulator deburring device generally...

Problems solved by technology

However, the pneumatic drive needs to be equipped with an air compressor, and a dry and clean air source and sealing device are required

It still has defects such as small application range, high requirements for sealing, difficult to achieve accurate speed control, large airflow noise and high power cost.

[0005] 3. Regardless of the spring or pneumatic buffer, the high-speed rotating shaft will inevitably contact the buffer device, resulting in greater friction and noise
