Description

[0002] A shaft is a mechanical part that supports a rotating part and rotates with it to transmit motion, torque, or bending moment. It is generally in the shape of a metal round rod, and each section can have a different diameter. The parts that make a rotary motion in a mechanical device / product are installed on the shaft. After the shaft is processed, chamfering treatment is usually required at both ends to facilitate the connection of other parts to the shaft.

[0039] A receiving box 7 for storing finished products is further arranged on one side of the chamfering mechanism 5. A chip receiving port is formed in its lower side. A dust collector 82 is arranged in the frame 1. A dust suction pipe 81 is arranged between the chip receiving port and the dust collector 82.

[0040] The working principle of the present invention is as follows:

[0041] The linear parts to be chamfered are placed into the vibrating bowl 21. The vibrating bowl 21 sequentially transports the parts onto the conveying track 22. The parts slide along the conveying track 22 to the temporary storage table 23. The first air claw 34 of the material taking mechanism 3 drives the first clamping arm 35 to move relatively closer along the clamping groove 24. After clamping and fixing the parts, the first rotary cylinder 32 drives the first air claw 34 to rotate 180°, and at the same time, the first cylinder 31 drives the first air claw 34 to rise, thus lifting the parts.

[0042] Start the manipulator 41 of the feeding mechanism 4. Remove the part clamped by the first gripper 34 through the second gripper 45 and the second clamping arm 47, and then transport it to the center of the first chuck 505 of the chamfering mechanism 5. When the piston rod of the second cylinder 43 extends, drive the push rod 49 to push the part into the first chuck 505. After the part extends to an appropriate depth, the first chuck 505 fixes the part. Then the first linear module 502 moves downward to make the part move towards the grinding wheel 510 and chamfer one end. A protective cover 511 is arranged on the outer side of the grinding wheel of the grinding wheel 510 to prevent waste chips from splashing and ensure the safety of the operator.

[0043] While the first part is being chamfered, the manipulator 41 drives the second gripper 45 and the second clamping arm 47 to remove the second part from the feeding mechanism 2. After the first part is chamfered, the first linear module 502 resets. The manipulator 41 drives the third gripper 46 and the second clamping arm 47 to remove the first part fixed in the first chuck 505, and then complete the feeding of the second part to the first chuck 505 through the second gripper 45, the second clamping arm 47, the second cylinder 43 and the push rod 49.

[0044] After the feeding of the second part is completed, the chamfering mechanism 5 chamfers the second part and resets. At the same time, the manipulator 41 drives the third gripper 46 and the second clamping arm 47 to transport the first part to the second chuck 64 at the upper end. After the second chuck 64 fixes the first part, the second rotary cylinder 62 rotates to make the first part in the vertical direction. Then start the second linear module 65 to drive the third chuck 67 to move upward to transfer the first part from the second chuck 64 to the third chuck 67, and then the third rotary cylinder 66 rotates outward to complete the flipping of the part end.

[0045] After the flipping of the first part end, the manipulator 41 drives the second gripper 45 and the second clamping arm 47 to remove the first part on the third chuck 67, and remove the second part fixed on the second chuck 64 through the third gripper 46 and the second clamping arm 47 and complete the feeding of the first part. Then the chamfering mechanism 5 chamfers the other end of the first part, and the manipulator 41 drives the second part to the flipping mechanism 6 for end flipping. At the same time, the manipulator 41 drives the second gripper 45 and the second clamping arm 47 to remove the third part from the feeding mechanism 2. After the first part is chamfered, the manipulator 41 drives the third gripper 46 and the second clamping arm 47 to remove the first part from the first chuck 505 and place the third part on it. The manipulator places the processed first part into the receiving box 7.

[0046] Remove the second part from the flipping mechanism 6, then remove the third part from the first chuck 505 and place the second part onto the first chuck 505, then place the third part onto the flipping mechanism 6, while removing the fourth part. Repeat the above actions to achieve batch automatic chamfering of the parts.

[0047] While performing the chamfering process, start the vacuum cleaner 82. The vacuum cleaner sucks the waste chips through the chip collection port and collects them through the suction pipe 81 to prevent the waste chips from affecting the equipment processing.

[0048] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
