[0032] This embodiment provides an electrode polishing assembly that can be used to polish the surface of an electrode and can adaptively adjust its size to completely polish the surface of the electrode.
[0033] Please refer to Figure 1-4The electrode grinding assembly provided in this embodiment includes a grinding piece 1 and a fastening and adjusting unit 2. One end of the grinding piece 1 is provided with at least two grinding claws 11 arranged at intervals along the circumference of the grinding piece 1. The grinding claws 11 can undergo elastic deformation. A plurality of grinding claws 11 enclose a receiving space 13. The inner wall of the grinding claws 11 forms a grinding surface. The workpiece 100 to be polished can extend into the receiving space 13 and be polished by the grinding surface. The fastening and adjusting unit 2 includes a fastening strap 21 and a locking piece 22. The fixed end of the fastening strap 21 is provided with a locking hole 211. The movable end of the fastening strap 21 passes through the locking hole 211 and can be selectively locked or unlocked relative to the fixed end by the locking piece 22. The fastening and adjusting unit 2 is used to make the grinding claws 11 undergo elastic deformation and adjust the elastic deformation degree of the grinding claws 11 so that the grinding surface can contact the surface of the workpiece 100 to be polished.
[0034] Specifically, the workpiece 100 to be polished can enter the accommodating space 13 through the opening at one end of the accommodating space 13, and the movable end of the fastening tie 21 passes through the locking hole 211. When the polishing surface is completely in contact with the surface of the workpiece 100 to be polished, the locking piece 22 cooperates with the locking hole 211 to lock the movable end of the fastening tie 21 with the fixed end, and the surface of the workpiece 100 to be polished is polished by relative rotation between the polishing claw 11 and the workpiece 100 to be polished, which can improve the polishing effect. The polishing device will be continuously worn during repeated use. In addition, the size of the electrode will continue to decrease after repeated polishing. Both of them will cause the polishing device to be unable to fit the electrode surface. At this time, the locking piece 22 is used to unlock the movable end of the fastening tie 21 with the fixed end, and the movable end of the fastening tie 21 is adjusted to elastically deform the polishing claw 11 until the polishing surface is completely in contact with the surface of the workpiece 100 again. The movable end of the fastening tie 21 is locked with the fixed end again, and polishing is continued to ensure the polishing effect.
[0035] For further information, please refer to Figure 1 The grinding claw 11 includes a grinding sandpaper 111 and a mounting portion 112 that can be elastically deformed. The grinding sandpaper 111 is arranged on the inner side of the mounting portion 112, and the inner side of the grinding sandpaper 111 forms a grinding surface. Exemplarily, in order to improve the grinding efficiency of the grinding piece 1, the grinding sandpaper 111 completely covers the inner side of the mounting portion 112, so that the grinding surface can completely cover the surface of the to-be-grinded piece 100 entering the accommodating space 13, and the grinding efficiency of the grinding piece 1 on the to-be-grinded piece 100 is higher. Specifically, the mounting portion 112 can be made of plastic to facilitate deformation of the mounting portion 112, and the fastening tie 21 is used to fasten it to achieve the purpose of adjusting the elastic deformation degree of the mounting portion 112.
[0036] For further information, please refer to Figure 1In order to ensure that the sandpaper 111 and the mounting portion 112 are firmly installed, the sandpaper 111 is bonded to the inner side of the mounting portion 112. The bonding is used to improve the firmness of the installation between the sandpaper 111 and the mounting portion 112 to avoid the sandpaper 111 shifting due to the rotation of the workpiece 100 relative to the sanding claw 11 during the sanding process. Since the sandpaper 111 itself has a certain hardness, the sandpaper 111 is not easy to wrinkle during the sanding process to affect the sanding effect.
[0037] For further information, please refer to Figure 1 In order to facilitate the operator to hold, the electrode grinding assembly also includes a handle 3, which is connected to the end of the grinding piece 1 away from the grinding claw 11. By providing the handle 3, the area that can be held is increased, making the grinding operation simpler and more convenient.
[0038] For further information, please refer to Figure 1 In order to prevent the operator from slipping while holding the handle 3 during the grinding process, an anti-slip protrusion is provided on the outer surface of the handle 3 to increase the friction force generated when the handle 3 is held.
[0039] For further information, please refer to Figure 1 In order to prevent the fastening tie 21 from moving along the extension direction of the grinding claw 11, a positioning piece 12 is provided on the outer surface of the grinding claw 11, and the positioning piece 12 can limit the fastening tie 21 from moving along the extension direction of the grinding claw 11. Specifically, the positioning piece 12 extends along the extension direction of the grinding claw 11, and both ends of the positioning piece 12 are connected to the outer surface of the grinding claw 11. The positioning piece 12 and the outer surface of the grinding claw 11 are surrounded by a positioning hole, and the fastening tie 21 passes through the positioning hole. After the fastening tie 21 passes through the positioning hole, the movement of the fastening tie 21 along the extension direction of the grinding claw 11 is limited in the positioning hole, thereby preventing the fastening tie 21 from moving along the extension direction of the grinding claw 11. In other embodiments, the positioning piece 12 can be a positioning groove provided on the outer surface of the grinding claw 11, and the fastening tie 21 can be clamped in the positioning groove.
[0040] For further information, please refer to Figure 2 In order to improve the adjustment effect of the fastening strap 21 on the aperture of the accommodating space 13, each grinding claw 11 is provided with a plurality of positioning members 12 along the extension direction of the grinding claw 11. The positioning members 12 at the same height along the extension direction of the grinding claw 11 are grouped as one, and each fastening strap 21 corresponds to each group of positioning members 12. By providing a plurality of groups of positioning members 12 along the extension direction of the grinding claw 11, the force on the grinding claw 11 can be made more uniform, so that the grinding surface fits more completely with the surface of the workpiece 100 to be polished, and the grinding effect is better.
[0041] Furthermore, the positioning member 12 and the mounting portion 112 are integrally formed. In other embodiments, the positioning member 12 may be mounted on the outer surface of the mounting portion 112 by fasteners.
[0042] For further information, please refer to Figure 3 In this embodiment, a limiting groove 212 is provided on the inner wall of one side of the locking hole 211 and penetrates the locking hole 211 axially. The locking hole 211 is connected with the limiting groove 212. The movable end of the fastening strap 21 passes through the locking hole 211 through the limiting groove 212. The inner wall of the locking hole 211 is provided with a thread. The outer side of the movable end of the fastening strap 21 is provided with a thread. The locking member 22 is an adjusting screw. The adjusting screw cooperates with the thread of the inner wall of the locking hole 211 to press the movable end penetrated in the limiting groove 212 against the inner bottom wall of the limiting groove 212, so as to lock the movable end of the fastening strap 21 relative to the fixed end. When the elastic deformation degree of the grinding claw 11 needs to be readjusted, the movable end of the fastening strap 21 can be unlocked relative to the fixed end by screwing the adjusting screw out of the locking hole 211.
[0043] Furthermore, in order to enhance the locking effect of the locking piece 22 on the movable end of the fastening tie 21, a plurality of through holes arranged at intervals are provided at the movable end of the fastening tie 21. During the process of tightening the adjusting screw, the through holes can cooperate with the adjusting screw so that the external thread of the adjusting screw is inserted into the near through holes, thereby making the locking of the movable end of the fastening tie 21 relative to the fixed end more secure.
[0044] Specifically, the fastening tie 21 can be made of stainless steel, which can extend the service life of the fastening tie 21 and enhance the fastening effect of the fastening tie 21. Of course, in other embodiments, the fastening tie 21 can also be an ordinary plastic tie with a self-locking function in the prior art, and the locking piece 22 can be removed.
[0045] Please refer to Figure 4 The specific working process of the electrode grinding assembly provided in this embodiment is as follows:
[0046] S1. Use a screwdriver to adjust the adjusting screw to loosen the fastening tie 21 so that the grinding claw 11 can restore its elastic deformation. Insert the workpiece 100 to be polished into the electrode polishing assembly. Use a screwdriver to adjust the adjusting screw to tighten the fastening tie 21 so that the grinding claw 11 can be elastically deformed until the polishing surface fits the surface of the workpiece 100 to be polished.
[0047] S2. Fix the workpiece 100 to be polished with one hand and rotate the handle 3 with the other hand. After repeated rotation for several times, observe the polishing condition of the workpiece 100 from the gap between the polishing claws 11. If the polishing effect is not good, use a screwdriver to adjust the adjusting screw to tighten the fastening tie 21 and rotate repeatedly until the surface of the workpiece 100 to be polished turns silver-white when observed from the gap between the polishing claws 11.
[0048] S3. Use a screwdriver to adjust the adjustment screw, loosen the fastening tie 21, remove the workpiece 100 from the electrode polishing assembly, and use high-purity water to rinse the surface of the workpiece 100 to be polished. The polishing is completed.
