Description

Technical Field

[0001] The utility model relates to the technical field of pressure equalizing ring processing, in particular to a positioning structure for pressure equalizing ring processing. Background Art

[0002] The grading ring is a ring-shaped hardware that improves the voltage distribution of the insulator string. The function of the grading ring is to prevent side lightning strikes. It is suitable for AC voltage and can evenly distribute high voltage around the object to ensure that there is no potential difference between the various parts of the ring, thereby achieving the effect of voltage grading.

[0003] During the production of the equalizing ring, it is produced and formed through steps such as casting, splicing and fixing, and center calibration. However, during casting and splicing, its surface often has burrs, protrusions and other redundant parts, which will affect the installation and use of the equalizing ring. Therefore, after casting and splicing, the equalizing ring needs to be ground and polished; and before grinding and polishing, the equalizing ring needs to be placed on a positioning device for fixation to ensure the stability of the equalizing ring during grinding and polishing. However, the positioning device needs to contact the equalizing ring to fix the equalizing ring, which also causes the positioning device to partially block the equalizing ring. Therefore, during grinding and polishing, the polishing process needs to be paused to shift the equalizing ring to ensure that the equalizing ring is fully polished, but such a pause operation also delays the processing progress of the equalizing ring.

[0028] A first support seat 3 and a second support seat 25 are respectively installed at both ends of the top of the base 1, and a first clamping member and a second clamping member are respectively provided on the top of the first support seat 3 and the second support seat 25 on the side relatively close to each other;

[0029] like Figure 1 and Figure 3 As shown, a drive shaft 4 is vertically mounted on the middle portion of a side of the first clamping member away from the second clamping member, and the other end of the drive shaft 4 is mounted on a first drive motor 5. The first drive motor 5 is mounted on a side of the first support base 3 away from the first clamping member, and the drive shaft 4 is rotatably connected to the first support base 3, so that the operation of the first drive motor 5 can drive the first clamping member to rotate;

[0030] Among them, Figure 1 and Figure 4 As shown, the first clamping member includes an arc-shaped first U-shaped seat 6, the opening of the first U-shaped seat 6 is set away from the drive shaft 4, and the first U-shaped seat 6 is fixed to the end of the drive shaft 4. A plurality of first support wheels 8 are arranged at intervals along the arc direction of the first U-shaped seat 6, and the end of the first support wheel 8 is rotatably connected to the inner wall of the first U-shaped seat 6 through the first connecting shaft 7. The rotation of the first support wheel 8 does not affect the rotation of the object with it.

[0031] Specifically, a second drive motor 24 is installed on one of the first connecting shafts 7, and the second drive motor 24 is fixed to the outer wall of the first U-shaped seat 6 through a bracket. Each first connecting shaft 7 is coaxially mounted with at least one sprocket 22, and two adjacent sprockets 22 are connected by a chain 23. The operation of the second drive motor 24 provides power for the rotation of the first support wheel 8, and the transmission of the chain 23 also allows all the first support wheels 8 to rotate in the same direction.

[0032] It should be noted that a protective cover is provided on the outer wall of the first U-shaped seat 6, wherein the sprocket 22, the chain 23, and the second drive motor 24 are all placed in the protective cover, so that the sprocket 22, the chain 23, and the second drive motor 24 can be wrapped and protected to prevent debris from falling on the chain 23 or the sprocket 22 and affecting the normal transmission of the chain 23.

[0033] Furthermore, in order to ensure the normal power supply of the second drive motor 24 and prevent the power supply wire of the second drive motor 24 from being wound and damaged due to the rotation of the drive shaft 4, an electric slip ring is provided on the drive shaft 4. The electric slip ring includes a stator 10 and a rotor 9. The stator 10 is coaxially fixed on the drive shaft 4, and the stator 10 is connected to the second drive motor 24 through a wire, and the rotor 9 is rotationally connected to the stator 10, and the rotor 9 is also fixed to the first support seat 3 through the support frame 21.

[0034] In addition, an annular slide rail 11 is installed on the side of the first support seat 3 close to the first U-shaped seat 6. The first slide rail 11 is coaxially arranged with the drive shaft 4, and at least one slider 12 is slidably installed on the first slide rail 11. The slider 12 is fixed to the first U-shaped seat 6 through a connecting rod 13, providing guidance and support for the rotation of the first U-shaped seat 6, thereby ensuring the stability of the first U-shaped seat 6 during rotation.

[0035] like Figure 1 and Figure 2 As shown, a pushing mechanism 18 is rotatably mounted on the middle portion of the second clamping member away from the first clamping member. The pushing mechanism 18 is fixed to the second support base 25. In actual use, the pushing mechanism 18 is an electric push rod, a pneumatic cylinder, or a hydraulic cylinder, which can drive the second clamping member to move closer to or away from the first clamping member.

[0036] The second clamping member includes an arc-shaped second U-shaped seat 14, the opening of the second U-shaped seat 14 is arranged away from the pushing mechanism 18, and the second U-shaped seat 14 is fixed to the pushing mechanism 18.

A connecting frame 17 is installed at the end of the pushing mechanism 18, and a rotating shaft 20 is vertically installed on the other side of the connecting frame 17. The other end of the rotating shaft 20 is rotatably connected to the second U-shaped seat 14, allowing the second clamping member to rotate on the pushing mechanism 18;

[0037] Furthermore, a guide shaft 19 is provided parallel to the side of the pushing mechanism 18, one end of the guide shaft 19 is fixed on the connecting frame 17, and the other end of the guide shaft 19 slides through the second support seat 25, providing a guide for the linear motion of the second U-shaped seat 14, ensuring the stability of the second U-shaped seat 14 during movement, and preventing the second U-shaped seat 14 from being misaligned with the first U-shaped seat 6, resulting in the two being unable to be aligned.

[0038] Specifically, when in use, take the pressure equalizing ring to be polished (such as Figure 5 The second driving motor 24 can also be started to rotate the first supporting wheel 8, thereby driving the pressure equalizing ring to rotate about its own axis, so as to move the area shielded by the U-shaped seat to the pressure equalizing ring outward, so as to fully grind and polish the surface of the pressure equalizing ring, which not only saves the operation of manual turning and adjustment during the grinding process, but also saves processing time.

[0039] It should be noted that the surface of each first support wheel 8 and the surface of each second support wheel 16 are wrapped with a non-slip rubber sleeve, which increases the contact friction between the support wheel and the equalizing ring and improves the driving force of the first support wheel 8 on the equalizing ring when it rotates.

[0040] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this.
