[0002] The purposes of grinding the inner wall of the metal pen shell mainly include the following aspects: removing surface impurities and oxide layers: during the processing or storage of metal materials, oxides, processing residues or dirt may adhere to the inner wall. Grinding can effectively remove these substances, ensure the cleanliness of the inner wall, and avoid interference of impurities with the internal structure of the pen or ink flow; improving surface smoothness and corrosion resistance: grinding can eliminate burrs or minute unevenness on the metal inner wall, form a smoother surface, and on the other hand, reduce the risk of local corrosion caused by surface roughness and extend the service life of the pen shell, etc.

[0015] A metal pen includes the pen shell body, and the pen shell body is polished by using this inner wall grinding device.

[0016] The present invention has the following beneficial effects:

[0017] 1. In the inner wall grinding equipment for processing metal pen shells, through the cooperation of the servo motor, the toothed disc and the gear, the grinding head and the dust suction seat fixed on the first hollow rod can rotate synchronously, so as to grind the inner wall of the pen shell body fixed on the clamping seat and clean the waste chips. The position of the mounting plate can be adjusted by the servo cylinder, so as to prompt the grinding head to adjust the grinding position on the inner wall of the pen shell body. When the grinding head returns to grind on the pen shell body, one end of the first hollow rod is connected to the dust suction equipment through a rotary joint, and the negative pressure flows into the dust suction seat through the first hollow rod. The waste chips ground off are adsorbed through the suction port of the dust suction seat. At the same time, affected by the adsorption force, the circular plate drives the second hollow rod, the conical contact block and the second contact block to move synchronously, so as to prompt the second contact block to contact with the sliding bracket, and the purpose of moving the brush plate to abut against the inner wall of the pen shell body can be achieved. During the rotation of the brush plate, the waste chips on the inner wall of the pen shell body can be brushed off, improving the waste chip cleaning effect;

[0018] The guide rod makes the movement of the mounting plate relatively stable. At the same time, when the guide rod moves in the clamping seat, it can achieve the purpose of contacting with the adjusting component, prompting the adjusting component to automatically adjust the position of the clamping bracket, so that the pen shell body can be automatically and firmly fixed on the clamping seat during the grinding process, improving the stability of grinding.

[0019] 2. For the inner wall grinding equipment for processing metal pen shells, in order to further improve the waste chip adsorption effect, when the conical contact block contacts with several second contact rods, the initial position of the sector baffle is in a parallel folding state with the pen shell body, which is convenient for the sector baffle in the folding state to drive the connecting piece to stretch out on the dust suction seat and abut against the inner wall of the pen shell body, greatly reducing the air circulation gap between the dust suction seat and the pen shell body. On the one hand, it can prevent waste chips from splashing to the clean side of the pen shell body where the waste chips have been adsorbed, affecting the waste chip cleaning effect. On the other hand, it can reduce the leakage area of the negative pressure in the pen shell body, so that the negative pressure can be concentrated between the dust suction seat and the grinding head, greatly improving the waste chip adsorption effect. At the same time, when the sector baffle extends, it can achieve the purpose of contacting with the second contact rod, prompting the comb tooth plate to clean the waste chips attached to the bristles of the brush plate, improving the working efficiency of the brush plate;

[0020] During the preliminary grinding, the protective cover can reduce the contact between the waste chips and the nozzle, avoiding damage to the nozzle of the nozzle and affecting the spraying of the protective layer. When the sector baffle extends, the protective cover can be moved out from one side of the nozzle through linkage, so that the nozzle can be exposed for use when working.

[0021] 3. In the inner wall grinding equipment for processing the metal pen shell, when the grinding head on the first hollow rod rotates, the fourth contact rod can intermittently contact a number of fifth contact blocks, prompting the second contact bracket to reciprocally contact the third contact rod, and achieving the purpose of the third contact bracket reciprocally contacting the third contact block. When the brush plate works, it closely adheres to the inner wall of the pen shell body and reciprocates, reducing cleaning dead corners and improving the cleaning efficiency of waste chips. The treatment liquid sprayed by the nozzle can be evenly attached to the inner wall of the pen shell body, improving the quality of the protective layer spraying. When the brush plate reciprocates, it can reciprocally contact the second L-shaped contact strip, enabling the second L-shaped contact strip to push the nozzle to reciprocally deflect on the second mounting block, increasing the spraying range of the nozzle, reducing spraying dead corners, and further improving the spraying quality and uniformity of the nozzle.

[0040] When the pen shell body 2 is ready to be ground, refer to Figures 1 - 4 , first place it on the clamping seat 3. The motor shaft of the servo motor 38 drives the gear 39 to rotate. When the gear 39 meshes with the toothed disc 40, the purpose of rotating the first hollow rod 4 on the mounting plate 37 can be achieved. At the same time, the grinding head 5 and the dust suction seat 6 rotate synchronously.

On the one hand, it can prevent waste chips from splashing onto the side of the pen shell body 2 that has been adsorbed clean, affecting the waste chip cleaning effect. On the other hand, it can reduce the leakage area of the negative pressure in the pen shell body 2, so that the negative pressure can be concentrated between the dust suction seat 6 and the grinding head 5, greatly improving the adsorption effect of waste chips.
