Description

Technical Field

[0001] This utility model relates to the field of suspension insulator production technology, and in particular to a special clamping mechanism for an automatic forming production line of suspension insulators. Background Technology

[0002] Suspension insulators are generally constructed by gluing insulating components (such as porcelain or glass components) and metal fittings (such as steel feet, iron caps, and flanges) together with adhesive or mechanically clamping them together. Insulators are widely used in power systems and are generally external insulators, operating under atmospheric conditions. Overhead transmission lines, busbars in power plants and substations, and the external energized conductors of various electrical equipment must be supported by insulators to insulate them from the ground (or grounded objects) or other conductors with a potential difference.

[0003] In the production process of suspension insulators, spinning is a key step. During spinning, the pre-formed blank is located in the lower forming mold. After being spun by the upper forming mold, the formed suspension insulator will remain on the lower forming mold. Subsequent processes require separating the suspension insulator from the lower forming mold and transporting them to the corresponding workstations. How to efficiently and smoothly separate the formed suspension insulator from the lower forming mold and transport them to the corresponding workstations has become an urgent technical problem to be solved.

The clamping mechanism includes a clamping mechanism body connected to the industrial robot 4. The clamping mechanism body includes a connecting bracket 2, on which a first clamping arm 21 and a second clamping arm 22 are provided symmetrically. The connecting bracket 2 is connected to the moving mechanism 3 and the suction cup 210 connected to the moving mechanism 3. In the first state, the moving mechanism 3 drives the suction cup 210 to move to the central axis position away from the first clamping arm 21 and the second clamping arm 22. In the second state, the moving mechanism 3 drives the suction cup 210 to move to the central axis position between the first clamping arm 21 and the second clamping arm 22.

[0015] In a preferred embodiment, based on the lower forming mold body 1, a cylindrical limiting part 12 is provided on the side of the lower forming mold body 1, and an arc-shaped groove 23 matching the cylindrical limiting part 12 of the lower forming mold body 1 is provided on the inner side of the first clamping arm 21 and the second clamping arm 22.

[0016] In a preferred embodiment, the moving mechanism 3 includes a third slide rail 31, a sliding block 32, a first linear drive member 33, a rotating shaft 34, a first connecting rod 35, and a second connecting rod 36. The connecting bracket 2 is connected to a third slide rail 31, and a sliding block 32 is slidably connected to the third slide rail 31. The connecting bracket 2 is provided with a first linear drive 33 in the same direction as the third slide rail 31. The first linear drive 33 is connected to the sliding block 32. The connecting bracket 2 is connected to a rotating shaft 34. The middle part of the first connecting rod 35 is pivotally connected to the rotating shaft 34. One end of the first connecting rod 35 is connected to a second linear drive 211. The second linear drive 211 is connected to a suction cup 210. The other end of the first connecting rod 35 is pivotally connected to a second connecting rod 36. The other end of the second connecting rod 36 is pivotally connected to the sliding block 32.

[0017] In a preferred embodiment, the connecting bracket 2 is provided with a third linear drive member 24 and a fourth linear drive member 25 arranged symmetrically with opposite moving directions. The third linear drive member 24 is connected to a first slide block 28, and the fourth linear drive member 25 is connected to a second slide block 29. A first clamping arm 21 is connected to the first slide block 28, and a second clamping arm 22 is connected to the second slide block 29. The connecting bracket 2 is also provided with a first slide rail 26 and a second slide rail 27 that are parallel to each other. The first slide block 28 is slidably connected to the first slide rail 26, and the second slide block 29 is slidably connected to the second slide rail 27.

[0019] In a preferred embodiment, the second linear drive 211 is a cylinder, a hydraulic cylinder, or an electric cylinder; the third linear drive 24 is a cylinder, a hydraulic cylinder, or an electric cylinder.

[0020] In the above embodiments, after the suspension insulator is spun and formed on the lower forming mold body 1 in conjunction with the upper forming mold body 1, the suspension insulator remains on the lower forming mold body 1, the upper forming mold body moves upward and disengages from the suspension insulator, and the lower forming mold is supported by the support base below. At this time, the industrial robot 4 drives the connecting bracket 2 to move to the position of the lower forming mold, and the first clamping arm 21 and the second clamping arm 22 clamp the cylindrical limiting part 12 of the lower forming mold body 1. Then, the industrial robot 4 drives the clamped lower forming mold body 1 to move upward and disengage from the support base below. Then, the first linear drive member 33 is controlled to transmit power, causing the first connecting rod 35 to swing around the rotation axis 34 as the central axis, so that the suction cup 210 moves to the middle between the first clamping arm 21 and the second clamping arm 22. Below the axis position, the second linear drive 211 is controlled to drive the suction cup 210 to move upward and adhere to the air vent of the lower forming mold, thereby adsorbing the suspension insulator body through negative pressure. Then, the industrial robot 4 drives the connecting bracket 2 to flip, so that the suspension insulator body faces downward. The industrial robot 4 drives the connecting bracket 2 to move to the position of the suspension insulator body unloading point, and controls the second linear drive 211 to move, so that the suction cup 210 releases its adsorption on the lower forming mold body 1, so that the suspension insulator separates from the lower forming mold under the action of gravity, completing the unloading of the suspension insulator body. Then, the industrial robot 4 drives the connecting bracket 2 to flip again and move to the unloading position of the lower forming mold, releasing the first clamping arm 21 and the second clamping arm 22, completing the unloading of the lower forming mold body 1.
