Thus, a feature defined as "first", "second", etc. may explicitly or implicitly include one or more of the features.

[0039] Example 1

[0040] like Figures 1 to 9 As shown, the present invention provides a technical solution:

[0041] A rod kit internal and surface deburring system, which at least includes but is not limited to a feeding part 1, a clamping part 2, a burr removal part 3, a protective cover 4 and a supporting base 5, wherein a sinking platform 51 is arranged in the supporting base 5, the clamping part 2 is arranged on the sinking platform 51, the burr removal part 3 and the feeding part 1 are arranged on the supporting base 5, the protective cover 4 is arranged on the clamping part 2 and the burr removal part 3, the feeding part and the protective cover 4 are intersectingly arranged, and the clamping part 2 can clamp the part 10 in the feeding part 1 into the burr removal part 3 for burr removal.

[0042] Based on the above structure, this solution adopts the clamping part 2 for automated operation, avoiding the grinding error caused by manual operation. The clamping part 2 clamps the parts to be ground 10 in the feeding part 1 into the burr removal part 3 for brake grinding one by one. The protective cover 4 can prevent the waste chips generated by grinding from escaping outside the entire system, realizing the division of manual feeding and mechanical automated grinding operations, and ensuring the safety of construction workers.

[0043] As an example, a secondary positioning fixture 6 is also provided on the support base 5, and a standard support position 61 for placing various types of parts 10 may be provided on the secondary positioning fixture 6;

[0044] Based on the above structure, when the clamping part 2 clamps the part 10 to be polished, due to the arbitrariness of manual placement of the part 10, if it is polished directly according to the prescribed polishing trajectory after clamping, a large error will occur. Therefore, a secondary positioning fixture 6 is set during polishing. The clamping part 2 first clamps the part 10 to the standard support position 61 to keep the initial position of each part 10 consistent. Then the clamping part 2 clamps the part 10 again from the standard support position 61 at the prescribed position. At this time, polishing according to the prescribed motion trajectory can greatly improve the polishing accuracy and improve the polishing yield rate.

[0045] As an example, the feeding section 1 may include a feeding support table 11, a first feeding line 12 and a second feeding line 13; the first feeding line 12 and the second feeding line 13 are arranged in parallel, the feeding support table 11 is connected through one end of the protective cover 4, the front ends of the first feeding line 12 and the second feeding line 13 are arranged on the feeding support table 11, and the rear ends are arranged in the protective cover 4.

[0046] Based on the above structure, by setting up two parallel feeding lines, manual sequential feeding can be facilitated. After the first feeding line 12 completes feeding, it slides into the inside of the protective cover 4 to provide the original parts for the clamping part 2, and the materials on the second feeding line 13 are prepared manually. After the materials on the first feeding line 12 are processed, the second feeding line 13 supplies parts 10, and continuous operation is achieved alternately.

[0047] As an example, a safety alarm device, such as a safety grating, is also provided on the feed support platform 11 . The safety alarm device is provided on the contact portion between the feed support platform 11 and the protective cover 4 .

[0048] Based on the above structure, the safety alarm device is used for safety alarm. When the clamping part 2 is performing the clamping operation of the part 10 or the grinding operation of the part 10, if the safety alarm device detects an abnormality, it will trigger an alarm to improve the overall safety.

[0049] As an example, the first feed line 12 is the same as the second feed line 13, and the first feed line 12 may include a power piece 121, a sliding plate 122, a support plate 123, a material carrier plate 124 and a guide assembly 125; the power piece 121 is arranged in parallel between the guide assemblies 125, the sliding plate 122 is provided with a sliding groove that matches the guide assembly 125, and the sliding plate 122 is connected to the power piece 121; the support plate 123 is arranged on the sliding plate 122 through a U-shaped plate 126, and a locking hole 127 that matches the material carrier plate 124 is provided on the support plate 123, and a matching hole 128 is provided on the material carrier plate 124, and the position of the matching hole 128 matches the locking hole 127.

The guide assembly 125 is provided in two strips, so that the sliding plate 122 can move more accurately. By providing a locking hole 127 on the support plate 123, on the one hand, the loading plate 124 can be quickly positioned, and on the other hand, the loading plate 124 can be quickly disassembled and assembled, which is convenient for manual quick operation.

[0051] As an example, the first feed line 12 can also include an upper sealing plate 129, an end sealing plate 130 and a support column 131.

[0054] Based on the above structure, when the sliding plate 122 moves to contact with the first limit switch 132, it reaches the extreme position inside the sliding plate 122. At this position, the holding part performs a clamping operation. When the sliding plate 122 moves to contact with the second limit switch 133, it reaches the extreme position outside the sliding plate 122. At this position, manual loading operations are performed.

[0055] As an example, the clamping part 2 may include a robot arm 21 and a gripping arm 22; the robot arm is provided with a rotating part cooperating with the gripping arm 22, and a single clamping claw may be provided on the rotating part;

Multiple auxiliary motors 322 can be installed with more cutting tools to realize the cutting and grinding operations.

[0060] As an example, a chip collecting bucket 52 is also provided in the sinking plate; waste chips generated by grinding are gathered in the chip collecting bucket 52 for collection.
