Description

Technical Field

[0001] This invention relates to the field of pressure equalization ball processing technology, specifically to a spinning device for pressure equalization ball processing and its manufacturing process. Background Technology

[0002] An equalizing sphere is a metallic conductor sphere that is typically installed in the electric field distortion region of a high-voltage conductor. It utilizes the uniform radius of curvature of its spherical geometry to eliminate electric field concentration caused by sharp edges. The equalizing sphere is a key shielding component in high-voltage electrical equipment. Its core function is to actively control the electric field distribution on the conductor surface to prevent discharge phenomena caused by excessively high local electric field strength, thereby ensuring the insulation safety of the equipment.

[0003] Existing spinning equipment for equalizing spheres often uses a robotic arm to control the spinning wheel to spin the equalizing sphere blank. This operation requires high precision from the equipment, is difficult to process, and has a high production cost.

[0004] In summary, most existing spinning equipment for processing equalizing balls uses a robotic arm to control the spinning wheel to spin the equalizing ball blank, which has high precision requirements, high operational difficulty, and high production costs. Summary of the Invention

[0009] Preferably, the main support assembly includes a support frame disposed at one top end of the base, and a motor is disposed at one bottom end of the base.

[0010] Preferably, the output end of the motor is provided with a drive wheel, and a driven wheel matching the drive wheel is rotatably provided on one side of the support frame, and the diameter of the driven wheel is larger than the diameter of the drive wheel. A transmission belt is movably provided on the outer side of both the drive wheel and the driven wheel.

[0011] Preferably, a limiting sleeve connected to a driven wheel is rotatably provided on the other side of the support frame, and a clamp is provided at one end of the limiting sleeve.

[0012] Preferably, the jacket is internally movably provided with a mandrel shaft for supporting the equalizing ball blank, and the end of the mandrel shaft is spherical.

A traction rod is slidably provided inside the pressure block, and a pressure handle is rotatably provided on the top of the traction rod.

[0017] A preparation process for processing equalizing spheres includes the following steps:

[0018] Step 1: Select an equalizing ball blank made of aluminum alloy, check its surface for cracks, and then clean the equalizing ball blank.

[0019] Step 2: Insert the concave part of the equalizing ball blank into one end of the mandrel shaft, and then rotate the handwheel at one end of the positioning screw. The handwheel drives the positioning screw to rotate forward, so that the other end of the positioning screw is pressed against the top of the spherical surface of the equalizing ball blank. The cooperation between the mandrel shaft and the positioning screw forms a stable limit on the equalizing ball blank.

[0020] Step 3: Start motor 3. Motor 3 drives driven wheel 3 to rotate. Driven wheel 3 drives the spinning disc to move. Start motor 1. Motor 1 drives the core mold shaft to rotate, thereby driving the entire pressure equalizing ball blank to rotate. Then, motor 4 drives the transverse lead screw to rotate. Motor 4 controls the transverse lead screw to perform periodic forward and reverse rotation, thereby realizing the back-and-forth movement of the spinning disc.

[0021] Step 4: When the spinning discs approach the equalizing ball blank, start motor 2. Motor 2 drives the vertical lead screw to rotate forward, thereby gradually reducing the distance between the spinning discs. This allows for uniform spinning of the equalizing ball blank. After spinning, motor 2 drives the vertical lead screw to rotate in reverse, increasing the distance between the spinning discs. Subsequently, the spinning discs move away from the equalizing ball blank.

[0022] Step 5: After completing the spinning operation, the worker drives the positioning screw to reverse through the handwheel, so that the other end of the positioning screw is away from the top of the spherical surface of the equalizing ball blank, and then the spun equalizing ball blank is removed.

[0023] The beneficial effects of this invention are:

[0024] 1. In this invention, the vertical sliding seat slides along the vertical slide rail by rotating the vertical lead screw, thereby further adjusting the distance between the spinning disc and the equalizing ball blank to meet different processing requirements. Furthermore, during the reciprocating motion of the spinning disc, the equalizing ball blank can be uniformly spun at different positions by controlling the indirect movement between the spinning discs, which improves the versatility and processing flexibility of the equipment. The device has a simple structure and is easy to operate, greatly reducing the difficulty of spinning the equalizing ball blank and providing great convenience for the spinning operation of equalizing ball blank in actual production.

[0025] 2. In this invention, the ball-shaped end of the mandrel shaft can better match the pressure equalizing ball blank, providing stable support for the pressure equalizing ball blank and ensuring the positional accuracy of the blank during processing. Attached Figure Description

[0039] In this embodiment, specifically, the end of the threaded bushing 12 is provided with a compensation groove 39, and the end of the threaded bushing 12 is symmetrically provided with pressure blocks distributed vertically. A traction rod 40 is slidably provided inside the pressure block, and a pressure handle 41 is rotatably provided on the top of the traction rod 40.

[0040] A preparation process for processing equalizing spheres includes the following steps:

[0041] Step 1: Select an equalizing ball blank made of aluminum alloy, check its surface for cracks, and then clean the equalizing ball blank.

[0042] Step 2: Insert the concave part of the equalizing ball blank into one end of the core mold shaft 9, and then rotate the handwheel at one end of the positioning screw 13. The handwheel drives the positioning screw 13 to rotate forward, so that the other end of the positioning screw 13 is pressed against the top of the spherical surface of the equalizing ball blank. The cooperation between the core mold shaft 9 and the positioning screw 13 forms a stable limit on the equalizing ball blank.

[0043] Step 3: Start motor 3 28. Motor 3 28 drives driven wheel 3 30 to rotate. Driven wheel 3 30 drives spinning disc 27 to move. Start motor 1 3. Motor 1 3 drives core mold shaft 9 to rotate, thereby driving the entire pressure equalizing ball blank to rotate. Then motor 4 36 drives transverse lead screw 34 to rotate. Motor 4 36 controls transverse lead screw 34 to perform periodic forward and reverse rotation, thereby realizing the back-and-forth movement of spinning disc 27.

[0044] Step 4: When the spinning disc 27 approaches the equalizing ball blank, start motor 20. Motor 20 drives the vertical lead screw 18 to rotate forward, thereby gradually reducing the distance between the spinning discs 27. This allows for uniform spinning of the equalizing ball blank. After spinning, motor 20 drives the vertical lead screw 18 to rotate in reverse, increasing the distance between the spinning discs 27. Subsequently, the spinning discs 27 move away from the equalizing ball blank.

[0045] Step 5: After completing the spinning operation, the operator drives the positioning screw 13 to reverse through the handwheel, so that the other end of the positioning screw 13 is away from the top of the spherical surface of the equalizing ball blank, and then the spun equalizing ball blank is removed.

[0046] Working principle: When using the device, the concave part of the equalizing ball blank is inserted into one end of the mandrel shaft 9. Then, the handwheel at one end of the positioning screw 13 is rotated, driving the positioning screw 13 to rotate forward. This causes the other end of the positioning screw 13 to press against the top of the spherical surface of the equalizing ball blank. The cooperation between the mandrel shaft 9 and the positioning screw 13 forms a stable limit on the equalizing ball blank. Then, motor 3 28 is started, driving driven wheel 30 to rotate. Driven wheel 30 drives the spinning disc 27 to move. Then, motor 4 36 drives the transverse lead screw 34 to rotate, controlling the transverse lead screw 34 to periodically rotate forward and backward. This enables the spinning discs 27 to move back and forth. When the spinning discs 27 approach the equalizing ball blank, motor 20 is started, driving the vertical lead screw 18 to rotate clockwise, thus gradually reducing the distance between the spinning discs 27. This allows for uniform spinning of the equalizing ball blank. After spinning, motor 20 drives the vertical lead screw 18 to rotate counterclockwise, increasing the distance between the spinning discs 27. Subsequently, the spinning discs 27 move away from the equalizing ball blank. After completing the spinning operation, the operator drives the positioning screw 13 to rotate counterclockwise via the handwheel, so that the other end of the positioning screw 13 is away from the top of the spherical surface of the equalizing ball blank. Then, the spun equalizing ball blank is removed.

[0047] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
