Description

Technical Field

[0001] This disclosure relates to the technical field of grinding threaded connectors, and more particularly to a grinding device for threaded connectors. Background Technology

[0002] Before being put into use, bushing terminals need to undergo anti-corrosion treatments such as painting, galvanizing, and chrome plating to form an anti-corrosion layer, blocking contact with corrosive media and extending their service life. However, during long-term use, terminals are susceptible to oxidation and corrosion, leading to a decline in material performance or even failure. Currently, there are no specialized tools for cleaning the oxide layer and rust on the threaded joints of terminals, and most methods rely on manual cleaning with brushes and cloths. This method has significant drawbacks: manual operation is labor-intensive and inconvenient; the cleaning effect is poor, making it difficult to completely remove the oxide layer and rust; the work efficiency is low, consuming a large amount of manpower and time, failing to meet the high-efficiency requirements of maintenance work, and may also affect the quality of subsequent maintenance due to incomplete cleaning, thus affecting the reliability of power supply.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that the description of these embodiments is intended to aid in understanding the invention, but does not constitute a limitation thereof. The specific structural and functional details disclosed herein are merely for describing exemplary embodiments of the invention. However, the invention can be embodied in many alternative forms and should not be construed as being limited to the embodiments described herein.

[0020] like Figures 1 to 3 As shown, a threaded joint grinding device 100 is proposed according to an embodiment of the present disclosure, including: a driving part 110; a grinding part 120, one end of the grinding part 120 is connected to the driving shaft of the driving part 110, and the driving part 110 drives the grinding part 120 to rotate; a grinding cavity is formed inside the grinding part 120 for inserting the threaded joint 200 to be ground.

[0021] It is understood that this disclosure includes at least the following beneficial effects: The threaded joint grinding device 100 provided in the embodiments of this disclosure is provided with a driving part 110 and a grinding part 120. The grinding part 120 has a grinding cavity formed inside, into which the threaded joint 200 to be ground can be inserted. One end of the grinding part 120 is connected to the driving part 110, so that the driving part 110 drives the grinding part 120 to rotate, thereby performing all-round grinding of the threaded joint 200 through the rotating grinding cavity. This achieves efficient grinding and rust removal of the threaded joint 200, simplifies the operation process, reduces labor intensity, saves manpower and time costs, and ensures the effectiveness of removing oxide layers and rust, avoiding affecting the quality of subsequent maintenance work, providing convenience for maintenance work, ensuring power supply reliability, reducing power supply failures caused by terminal failure, enhancing power supply reliability, and saving overall operation and maintenance costs.

[0022] It should be noted that when dealing with threaded connectors 200 of different specifications, it is only necessary to replace the grinding part 120 with a grinding chamber of the corresponding size. Furthermore, the threaded connector grinding device 100 can not only grind the threaded connectors 200 of the terminal block, but also grind other columnar structures, thus improving adaptability.

[0023] In some examples, such as Figures 1 to 3 As shown, the grinding part 120 includes: a sleeve 121, one end of which is connected to the drive shaft of the drive part 110, and the other end of which has an opening; a grinding member 122, which is coiled around the inner wall of the sleeve 121, and the grinding member 122 forms the grinding cavity on the side away from the inner wall of the sleeve 121; wherein the threaded joint 200 to be ground is inserted into the grinding cavity from the opening side.

[0024] It is understood that the grinding section 120 may be provided with a sleeve 121 and a grinding element 122. Specifically, one end of the sleeve 121 is sealed and can be connected to the drive shaft of the drive section 110, thereby driving the sleeve 121 to rotate via the drive shaft, and facilitating disassembly and assembly to ensure the convenience of subsequent maintenance and replacement; the other end of the sleeve 121 is provided with an opening to expose the internal space, so that the grinding element 122 can be spirally wound around the inner side wall of the sleeve 121. The side of the grinding element 122 facing away from the inner side wall of the sleeve 121 is the grinding end. After the grinding element 122 is spirally wound, the grinding end can be combined to form a grinding cavity, thereby driving the grinding cavity to rotate via the rotation of the sleeve 121, so as to perform all-round grinding of the threaded joint 200.

[0025] It should be noted that a coupling can be provided at the sealed end of the sleeve 121, and an adapter can be provided at the corresponding end of the drive shaft. The coupling is connected to the drive shaft through cooperation with the adapter, so that the drive shaft can drive the sleeve 121 to rotate synchronously. The coupling and the adapter can be connected by a snap-fit ​​structure for easy disassembly, maintenance and replacement.

[0026] In some examples, such as Figures 1 to 3 As shown, the above-mentioned grinding component 122 includes: a mounting edge 1221; and a grinding material 1222 disposed on one side of the mounting edge 1221; wherein, the other side of the mounting edge 1221 is spirally coiled around the inner wall of the sleeve 121 along the axial direction of the sleeve 121, so that the grinding material 1222 constitutes the grinding cavity.

[0027] It is understood that the grinding component 122 may be provided with an mounting edge 1221 and a grinding material 1222. The mounting edge 1221 may be made of a malleable metal part to improve the structural strength of the mounting edge 1221. The grinding material 1222 may be provided on one side of the mounting edge 1221, and the other side of the mounting edge 1221 may be spirally coiled around the inner wall of the sleeve 121 along the axial direction of the sleeve 121. Thus, by adjusting the shape of the mounting edge 1221, the overall shape of the grinding material 1222 is changed so that the grinding material 1222 forms a grinding cavity with a spiral coiled shape, and the overall length of the grinding cavity is greater than or equal to the length of the threaded joint 200 to be ground, so as to ensure all-round grinding of the threaded joint 200.

[0028] In some examples, the pitch of the spirally wound mounting edge 1221 is 20 ± 0.2 mm.

[0029] Understandably, after the mounting edge 1221 is spirally coiled, the entire mounting edge 1221 is spiral-shaped. To ensure the grinding chamber can effectively grind the threaded joint 200 from all directions, the pitch of the spiral mounting edge 1221 needs to be adjusted. If the pitch is too large, the gap between adjacent grinding material sections 1222 will be too large, creating grinding dead angles and making it difficult to guarantee the grinding effect. If the pitch is too small, it will result in a large consumption of grinding material 1222 and a larger mounting edge 1221 size, and the installed grinding material 1222 will be too crowded, causing the grinding material 1222 to be crowded and deformed. Therefore, the pitch of the spiral mounting edge 1221 is adjusted to 20±0.2mm. On the one hand, this ensures that the gap between adjacent grinding material sections 1222 is set reasonably to guarantee the grinding effect; on the other hand, it ensures that the amount of material used and the arrangement of the grinding material 1222 are reasonable, improving reliability.

[0030] In some examples, the aforementioned polishing material 1222 includes: copper-plated steel wire, stainless steel wire, and nylon wire.

[0031] Understandably, the grinding material 1222 can be made of soft materials such as copper-plated steel wire, stainless steel wire, and nylon wire, and extends inward along the axial direction of the sleeve 121. The aforementioned soft materials have good flexibility and wear resistance, so as to ensure that the grinding part 120 can efficiently remove the oxide layer and rust on the surface of the threaded joint 200 through the grinding material 1222 during high-speed rotation. At the same time, it can avoid damage to the threaded joint 200 by the grinding material 1222, improve protection, and extend the service life of the grinding part 120 and the threaded joint 200.

[0032] In some examples, the mounting edge 1221 is welded to the inner wall of the sleeve 121.

[0033] It is understandable that the mounting edge 1221 can be made of metal to facilitate plasticity and ensure the reliability of the connection between the grinding material 1222 and the mounting edge 1221. Furthermore, the metal mounting edge 1221 can be installed on the inner wall of the sleeve 121 by welding to ensure a tight connection and prevent the mounting edge 1221 from falling off the inner wall of the sleeve 121 when the grinding part 120 rotates at high speed, thereby improving stability.

[0034] In some examples, such as Figure 1 As shown, the drive unit 110 includes: a housing 111, on which a handle 113 is provided; a motor 112, which is disposed inside the housing 111; and a drive shaft passing through the housing 111 and connected to the motor 112 via a gearbox.

[0035] Understandably, the drive unit 110 may include a housing 111, a motor 112, and a gearbox. The housing 111 can be designed for easy portability and includes a handle 113 for user grip and operation. The motor 112 can be installed within the housing 111, and the drive shaft can be connected to the motor 112 via the gearbox. The torque can be adjusted via the gearbox rack to ensure the drive shaft can drive the grinding unit 120 to rotate at high speed, thereby ensuring the grinding effect. It should be noted that the housing 111 may be made of lightweight material to reduce the overall weight of the threaded joint grinding device 100, thus facilitating operation.

[0036] In some examples, the handle 113 is an insulated handle 113, and the insulated handle 113 is provided with anti-slip texture.

[0037] Understandably, the handle 113 of the housing 111 can be made of insulating material or wrapped with insulating material to ensure the safety of grinding operations. Furthermore, anti-slip textures are provided on the insulating handle 113 to meet the needs of outdoor and high-altitude maintenance, improve the operator's operating feel, and facilitate use.

[0038] In some examples, such as Figure 1 As shown, the drive unit 110 further includes a rechargeable lithium battery 114, which is disposed inside the housing 111 and is used to supply power to the motor 112. The charging port of the rechargeable lithium battery 114 is opened in the housing 111.

[0039] It is understandable that the drive unit 110 may also be equipped with a rechargeable lithium battery 114. Specifically, the rechargeable lithium battery 114 may be located inside the housing 111 near the bottom, supplying power to the motor 112. The charging port of the rechargeable lithium battery 114 may be located in the housing 111 for charging with a charger. The rechargeable lithium battery 114 has a high capacity and is lightweight, which reduces the overall weight of the threaded joint grinding device 100 while maintaining a long operating range, making it easier to operate.

[0040] In some examples, such as Figure 1 As shown, the drive unit 110 also includes a speed control switch 115, which is disposed in the housing 111 and is used to adjust the speed of the motor 112.

[0041] It is understood that the drive unit 110 may also be equipped with a speed control switch 115. The speed control switch 115 is located in the housing 111 and electrically connected to the motor 112. By operating the speed control switch 115, the speed of the motor 112 can be adjusted in multiple stages. This allows for adjustment of the appropriate speed according to the grinding requirements of the threaded joints 200 with different degrees of corrosion, avoiding damage to the threaded joints 200 due to excessive speed or affecting the grinding effect due to excessive speed, thereby improving reliability and adaptability. For example, the speed control switch 115 may be a trigger structure, located on the front side of the handle 113, so that the operator can operate it with one hand, and adjusting the speed control switch 115 is simple and convenient.
