The grinding belt 25 in the first side plate 21 is a coarse grinding belt, and the grinding belt 25 in the second side plate 22 is a fine grinding belt. The first side plate 21 and the second side plate 22 in the burr removal mechanism 2 are arranged side by side up and down, and a rotating belt 24 and a grinding belt 25 are sleeved on the middle roller 23. At the same time, the grinding belts 25 on the first side plate 21 and the second side plate 22 are made of different materials, so that the metal stamping parts pass through the middle of the grinding belts 25 rotating in the two groups of burr removal mechanisms 2 from top to bottom. At the same time, a buffer pad 241 is installed between the rotating belt 24 and the grinding belt 25, so that the metal stamping parts are fully in contact with the grinding belts 25 of different coarse and fine materials, thereby playing a deburring role.

[0023] Both ends of the two adjacent roller shafts 23 on each group of first side plates 21 and second side plates 22 are sleeved with connecting plates 26, which play a connecting and limiting role. An auxiliary frame 211 is fixedly installed on the outer side of each first side plate 21, and sliding grooves are opened on both sides of the outer frame 1 corresponding to the auxiliary frames 211. The auxiliary frames 211 slide in the sliding grooves. The auxiliary frames 211 are slidably installed in the sliding grooves, which can support the burr removal mechanism 2 and also meet the movement of the burr removal mechanism 2.

[0024] Gears 27 are fixedly installed at both ends of the two adjacent roller shafts 23 in each group of the first side plate 21 and the second side plate 22. The two adjacent gears 27 on the outer sides of each group of the first side plate 21 and the second side plate 22 are meshed and transmitted.

[0026] Example 2

[0027] According to Example 1, the distance between the first side plates 21 in the two sets of burr removal mechanisms 2 in Example 1 is not easy to adjust the limit position.

The outer frame 1 has mounting seats 31 fixedly installed at both ends and the middle of the two outer sides. The bidirectional screw 32 is rotatably installed on the mounting seat 31. The bidirectional screw 32 is rotatably installed on the mounting seat 31 and threadedly connected to the auxiliary frame 211 in the spacing control mechanism 3, so that when the bidirectional screw 32 is rotated, the spacing between the first side plates 21 in the two groups of burr removal mechanisms 2 can be adjusted. On the one hand, it can adapt to the deburring of hardware stamping parts of different sizes. On the other hand, it can also intermittently fine-tune the spacing between the first side plates 21 in the two groups of burr removal mechanisms 2 during the deburring operation to optimize the deburring effect with different contact areas.

[0029] Motors are fixedly mounted on the outer sides of the mounting seat 31 and the first side plate 21 , and the output shaft of the motor is fixedly connected to the bidirectional screw 32 and the roller shaft 23 respectively.

[0030] Working principle: The roller shaft 23 is synchronously driven to rotate by a motor, and the driving rotation direction is opposite. When the roller shaft 23 in the middle of the first side plate 21 rotates, the gear 27 is meshed to drive the roller shaft 23 in the second side plate 22 to rotate, thereby driving the grinding belts 25 in the first side plate 21 and the second side plate 22 to rotate synchronously. The metal stamping parts pass through the middle of the grinding belts 25 rotating in the two groups of burr removal mechanisms 2 from top to bottom, so that the metal stamping parts are fully in contact with the grinding belts 25 of different coarse and fine materials, which plays a deburring role. The rotation of the bidirectional screw 32 is controlled by the motor to adjust the spacing between the first side plates 21 in the two groups of burr removal mechanisms 2. By controlling the extension and retraction of the telescopic rod 29, the spacing can be adjusted synchronously with the two groups of first side plates 21, and the spacing between the two groups of second side plates 22 can also be adjusted by autonomous extension and retraction control to optimize the grinding effect.
