Description

Technical Field

[0001] This utility model mainly relates to the field of forgings, and specifically to an adsorption clamp for moving forgings. Background Technology

[0002] Currently, common methods for handling forgings include mechanical clamping, magnetic adsorption, and vacuum adsorption. Among these, vacuum adsorption fixtures (or suction cup fixtures) are widely used because they do not cause mechanical damage to the surface of the forgings and are not limited by the magnetic properties of the forging material (especially suitable for non-magnetic materials such as aluminum alloys and stainless steel).

[0003] However, existing vacuum adsorption fixtures still have a significant technical drawback when handling forgings: uneven distribution of adsorption force, leading to a high risk of forgings falling off during movement. The root causes of this problem lie mainly in the following aspects: The complexity of forging surface morphology: Forging surfaces are not ideally smooth planes; they often contain undulations, oxide scale, microcracks, or draft angles caused by the forging process. When using traditional rigid-mounted suction cups, the lips of the suction cups cannot fully conform to these irregular surfaces, easily creating localized air leakage points. This not only reduces the overall vacuum level but also leads to significant differences in the actual suction force of each suction cup. Some suction cups may withstand excessive loads due to good contact, while others will generate almost no suction force due to air leakage, making the entire clamping system fragile and unstable.

[0004] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0007] Furthermore, the movable structure includes a housing, with mounting grooves on both sides of the outer wall of the housing and guide grooves on both sides of the inner wall of the housing, and the mounting grooves are slidably connected to the slider.

[0019] See attached document Figure 1-4 A forging moving adsorption clamp includes a moving structure 1, with limiting clamp structures 2 provided on both sides of the outer wall of the moving structure 1, and a main adsorption structure 3 provided directly below the moving structure 1. The limiting clamp structure 2 includes a slider 201, an adjusting bolt 202 rotatably connected to the top of the slider 201, and a rotating bar 203 rotatably connected to the bottom of the slider 201. A planar spiral spring is provided between the adjusting bolt 202 and the rotating bar 203. A fitting strip 204 is provided on the bottom inner side of the rotating bar 203, and an inclined groove 205 is formed at the bottom of the fitting strip 204. The number of rotating bars 203 is set to four, and a connecting strip 206 is provided between the four rotating bars 203. A pusher bar 207 is provided in the middle of the top of the connecting bar 206. During the downward movement of the housing 101, the outer wall of the forging contacts the bottom of the inclined groove 205, thereby pushing the bonding bar 204 to rotate along the connection position between the rotating bar 203 and the slider 201. After the bonding bar 204 has completely passed the forging, the planar spiral spring provided between the rotating bar 203 and the slider 201 is reset, so that the top of the bonding bar 204 is in contact with the bottom of the forging, supporting the forging and preventing the forging from falling off during adsorption and movement.

[0020] Furthermore, the movable structure 1 includes a housing 101. Mounting grooves 102 are provided on both sides of the outer wall of the housing 101, and guide grooves 103 are provided on both sides of the inner wall of the housing 101. The mounting grooves 102 are slidably connected to the slider 201. Side plates 104 are provided on both sides of the interior of the housing 101, and a bottom plate 106 is provided on the inner wall of the housing 101. A sliding rod 105 is provided between the side plates 104 and the housing 101, connecting the top of the housing 101 to a crane or other moving device, so that the movable structure 1 can be used to lift and move the forging after adsorption.

[0021] Furthermore, the main adsorption structure 3 includes a sliding bar 301, one end of which has a sliding hole 302. The sliding hole 302 is slidably connected to a sliding rod 105. A return spring 303 is provided between the sliding hole 302 and the sliding rod 105. A positioning shaft 304 is provided on the inner side of the sliding bar 301. A rotating rod 305 is provided on the outer wall of the positioning shaft 304. A rotating ring 306 is provided on one end of the rotating rod 305. The rotating ring 306 is rotatably connected to the positioning shaft 304. A positioning plate 307 is rotatably connected to the other end of the rotating ring 306. The bottom of the positioning plate 307 is provided with a suction cup assembly. When the housing 101 moves downward, the suction assembly at the bottom of the positioning plate 307 moves with the top of the forging to achieve suction of the forging. Then, when the housing 101 and the suction assembly move the forging upward, the weight of the forging can pull the positioning plate 307 downward. Then, the positioning plate 307 moves downward and pushes the rotating rod 305 to rotate. The rotating rod 305 pushes the sliding strip 301 to slide on the outer wall of the sliding rod 105 and stretches the sliding hole 302, so that the bottom of the forging is in contact with the outer wall of the limiting clamp structure 2. The suction cup assembly of the main adsorption structure 3 is made of flexible material and designed as a multi-chamber independent suction cup to better adapt to the irregular shape of the forging surface. Each suction cup can be connected to an independent vacuum channel to ensure that the overall adsorption force is maintained even if there is local air leakage.

[0022] Initial state: The clamp is connected to the hoist or moving device through the top of the housing 101 of the moving structure 1 and is in a suspended state.

[0023] Descent Phase: The moving structure 1 moves the entire clamp downwards. The suction cup assembly of the main adsorption structure 3 first contacts the top of the forging and fixes the forging by vacuum adsorption. At the same time, the inclined groove 205 of the fitting strip 204 of the limiting clamp structure 2 contacts the side surface of the forging. The forging pushes the fitting strip 204 to rotate around the connection point of the rotating strip 203 and the slider 201, compressing the planar spiral spring.

[0024] Adhesion stage: After the adhesion strip 204 has completely passed the bottom of the forging, the flat spiral spring returns to its original position, causing the adhesion strip 204 to rotate upward, so that its top is tightly adhered to the bottom of the forging, thus supporting the forging from the bottom.

[0025] Lifting stage: The moving structure 1 moves upward, the main adsorption structure 3 adsorbs the forging from the top through the suction cup assembly, while the limiting clamp structure 2 supports the forging from the bottom. The positioning plate 307 of the main adsorption structure 3 moves downward, pushing the rotating rod 305 to rotate around the positioning shaft 304, thereby pulling the sliding bar 301 to slide along the sliding rod 105 and stretching the return spring 303 to adapt to the shape and weight distribution of the forging and ensure stable adsorption.

[0026] Movement phase: After the fixture carries the forging to the target position, the moving structure 1 descends. When the contact strip 204 of the limiting clamp structure 2 contacts the support surface, the connecting strip 206 is manually pushed to rotate. The connecting strip 206 pushes the rotating strip 203 to rotate, so that the contact strip 204 is detached from the bottom of the forging, releasing the bottom support of the forging. At the same time, the vacuum adsorption of the main adsorption structure 3 is released, and the forging is safely placed.

[0027] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
