At the same time, the positioning accuracy of traditional fixtures is limited. Due to their insufficient fit with the part, slight displacement or positioning deviation of the part is prone to occur during the machining process, making it difficult to guarantee machining accuracy.

[0006] The adsorption mechanism includes a fixed rod, a lifting groove, a first motor, a lead screw, a slide rod, a lifting block, a lifting rod, a connecting rod, a suction cup, a suction tube, a valve, and a vacuum pump. A fixed rod is fixedly connected to the top of the base plate. A lifting groove is formed on one side of the fixed rod. The first motor is fixedly connected to the bottom of the lifting groove. A lead screw is fixedly connected to the upper surface of the first motor. A slide rod is fixedly connected to the inside of the lifting groove. Lifting blocks are slidably connected to the surfaces of both the lead screw and the slide rod. A lifting rod is fixedly connected to one side of the lifting block. A connecting rod is fixedly connected to the bottom of the lifting rod. A suction cup is fixedly connected to the bottom end of the connecting rod. A suction tube is fixedly connected to the top of the suction cup. A valve is provided on one side of the suction tube. A vacuum pump is fixedly connected to the top end of the suction tube.

[0007] Preferably, the mounting holes are provided in multiple sets on the surface of the base plate, and are symmetrically arranged at the four corners of the base plate with respect to the central axis of the base plate.

[0008] Preferably, multiple sets of the support feet are provided at the bottom of the positioning platform, and they are distributed in a cross shape at the bottom of the positioning platform with the center of the positioning platform in mind.

[0009] Preferably, two sets of fixing rods are provided on the surface of the base plate, and each set of fixing rods has a lifting groove on a corresponding side. One set of lifting grooves is connected to a lead screw, and the other set of lifting grooves is connected to a sliding rod.

[0010] Preferably, the position of the lifting block corresponds to the position of the lifting groove, and the outer wall dimension of the lifting block matches the inner wall dimension of the lifting groove.

[0011] Preferably, the dust collection mechanism includes a transfer chamber, a housing, a second motor, a rotating shaft, fan blades, a filter plate, and vents. The transfer chamber is fixedly connected to the surface of the top plate of the vacuum chamber. The housing is installed at the top of the transfer chamber. The second motor is fixedly connected to the inner side of the housing. The rotating shaft is fixedly connected to the bottom of the second motor.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This aluminum alloy part contour suction cup processing fixture, through the setting of the adsorption mechanism, when it is necessary to use the adsorption mechanism to adsorb and fix the aluminum alloy part, firstly, the first motor is started, driving the lead screw to rotate. Since the lifting block is simultaneously fitted on the lead screw and the slide rod, under the rotation of the lead screw and the guiding action of the slide rod, the lifting block will move vertically along the lifting groove. As the lifting block moves, the connected lifting rod drives the connecting rod and the suction cup to descend, bringing the suction cup close to the surface of the aluminum alloy part. Then, the vacuum pump is turned on and the valve is opened. The vacuum pump evacuates air from inside the suction cup through the suction pipe, creating a negative pressure environment inside the suction cup. Under the action of external atmospheric pressure, the suction cup tightly adsorbs onto the surface of the aluminum alloy part, thereby achieving the fixation of the part. This adsorption method can... It is effective in adapting to aluminum alloy parts of different shapes because the suction cup can automatically adjust the fit according to the contour of the part. Compared with traditional tooling, it greatly improves versatility. During the processing, because the suction cup is in close contact with the surface of the part and the adsorption force is evenly distributed on the contact surface between the suction cup and the part, it can effectively avoid the slight displacement and positioning deviation of the part, and significantly improve the positioning accuracy. Even when subjected to external forces such as cutting forces during processing, the suction cup can still stably adsorb the part, ensuring the accuracy of the part's position during processing, thereby guaranteeing the processing accuracy. It effectively solves the problem of difficulty in guaranteeing the processing accuracy caused by poor fit and inaccurate positioning of traditional tooling, improves the quality and reliability of aluminum alloy parts processing, reduces the scrap rate caused by positioning errors, lowers production costs, and improves production efficiency.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a tooling for processing aluminum alloy parts with a contour suction cup, including a base plate 1, an installation hole 2 on the surface of the base plate 1, a support foot 3 fixedly connected above the base plate 1, a positioning platform 4 fixedly connected above the support foot 3, a left and right suction mechanism 5 above the base plate 1, a top plate 6 above the suction mechanism 5, and a dust suction mechanism 7 on the surface of the top plate 6.

[0021] The adsorption mechanism 5 includes a fixed rod 501, a lifting groove 502, a first motor 503, a lead screw 504, a slide rod 505, a lifting block 506, a lifting rod 507, a connecting rod 508, a suction cup 509, a suction tube 510, a valve 511, and a vacuum pump 512. The fixed rod 501 is fixedly connected to the top of the base plate 1. A lifting groove 502 is formed on one side of the fixed rod 501. The first motor 503 is fixedly connected to the bottom of the lifting groove 502. A lead screw 504 is fixedly connected to the upper surface of the first motor 503. A slide rod 505 is fixedly connected to the inside of the lifting groove 502. Lifting blocks 506 are slidably connected to the surfaces of both the lead screw 504 and the slide rod 505. A suction cup 509, a suction tube 510, a valve 511, and a vacuum pump 512 are connected to one side of the lifting block 506. A lifting rod 507 is fixedly connected, and a connecting rod 508 is fixedly connected to the bottom of the lifting rod 507. A suction cup 509 is fixedly connected to the bottom end of the connecting rod 508, and a suction tube 510 is fixedly connected to the top of the suction cup 509. A valve 511 is provided on one side of the suction tube 510, and a vacuum pump 512 is fixedly connected to the top end of the suction tube 510. Through the setup of the adsorption mechanism 5, when it is necessary to use the adsorption mechanism 5 to adsorb and fix aluminum alloy parts, the first motor 503 is first started. The first motor 503 drives the lead screw 504 to rotate. Since the lifting block 506 is simultaneously fitted onto the lead screw 504 and the sliding rod 505, under the rotation of the lead screw 504 and the guiding action of the sliding rod 505, the lifting block 506 will... The lifting block 506 moves vertically along the lifting groove 502. As it moves, the lifting rod 507 connected to it drives the connecting rod 508 and the suction cup 509 to descend, bringing the suction cup 509 close to the surface of the aluminum alloy part. Then, the vacuum pump 512 is turned on and the valve 511 is opened. The vacuum pump 512 evacuates air from inside the suction cup 509 through the suction pipe 510, creating a negative pressure environment inside the suction cup 509. Under the action of external atmospheric pressure, the suction cup 509 tightly adheres to the surface of the aluminum alloy part, thus fixing the part. This adsorption method can effectively adapt to aluminum alloy parts of different shapes because the suction cup 509 can automatically adjust the fit according to the contour of the part, which is much better than traditional tooling. The improved versatility of the suction cup 509 enhances its versatility. During processing, the suction cup 509 adheres tightly to the surface of the part, and the adsorption force is evenly distributed on the contact surface between the suction cup and the part. This effectively avoids minor displacement and positioning deviations of the part, significantly improving positioning accuracy. Even when subjected to external forces such as cutting forces during processing, the suction cup 509 can still stably adsorb the part, ensuring the part's accurate position during processing and thus guaranteeing processing precision. This effectively solves the problem of difficulty in guaranteeing processing precision caused by poor fit and inaccurate positioning in traditional tooling. It improves the quality and reliability of aluminum alloy part processing, reduces the scrap rate caused by positioning errors, lowers production costs, and increases production efficiency.

[0022] Furthermore, multiple sets of mounting holes 2 are provided on the surface of the base plate 1, and are symmetrically arranged at the four corners of the base plate 1 with respect to the central axis of the base plate 1. The mounting holes 2 provide a rich and stable selection of fixing points for the entire tooling to be installed on the worktable of the processing equipment. This symmetrical distribution ensures that the tooling is subjected to uniform force after installation, avoiding tilting or displacement of the tooling due to improper installation, thereby providing a solid foundation for the processing of aluminum alloy parts, ensuring the stability and accuracy of the processing process. At the same time, multiple sets of mounting holes 2 also facilitate the adaptation of the tooling to processing equipment of different models and specifications, improving the versatility and compatibility of the tooling, reducing the trouble of redesigning the tooling installation structure due to equipment differences, and helping to reduce production costs and improve production efficiency.

[0023] Furthermore, multiple sets of support feet 3 are provided at the bottom of the positioning table 4, and are distributed in a "+" shape around the center of the positioning table 4. The support feet 3 provide stable and uniform support for the positioning table 4. When the aluminum alloy parts are placed on the positioning table 4 for processing, the "+" shaped distribution of support feet 3 can effectively distribute the weight of the parts and the tooling itself, preventing the positioning table 4 from deforming or sinking due to excessive local force. This ensures that the levelness and flatness of the positioning table 4 remain stable during the processing. A stable positioning table 4 helps to improve the positioning accuracy of the parts, reduce processing errors caused by the instability of the tooling base structure, and ensure the consistency and reliability of the processing quality of aluminum alloy parts.

[0024] Furthermore, two sets of fixing rods 501 are provided on the surface of the base plate 1, and each set of fixing rods 501 has a lifting groove 502 on a corresponding side. One set of lifting grooves 502 is connected to a lead screw 504, and the other set of lifting grooves 502 is connected to a slide rod 505. The fixing rods 501 and the lifting grooves 502 provide a stable and precise guiding structure for the lifting movement of the suction cup 509. The lead screw 504 connected to one set of lifting grooves 502 is used to provide power to achieve lifting, and the slide rod 505 connected to the other set plays an auxiliary guiding role. This design allows the lifting block 506 to run smoothly along a predetermined straight trajectory when driving the suction cup 509 to lift.

[0025] Furthermore, the position of the lifting block 506 corresponds to the position of the lifting groove 502, and the outer wall size of the lifting block 506 matches the inner wall size of the lifting groove 502. Through the setting of the lifting groove 502 and the lifting block 506, the accuracy and stability of the lifting process are further guaranteed. The precise dimensional matching effectively avoids the shaking or jamming of the lifting block 506 in the lifting groove 502, so that the suction cup 509 can accurately reach the predetermined position and achieve good adhesion and adsorption with the surface of the aluminum alloy part. This improves the gripping and fixing accuracy of the adsorption mechanism 5 on the part, thus laying the foundation for subsequent high-precision processing operations. It also helps to reduce processing waste caused by inaccurate positioning of the suction cup and improve production efficiency and product quality.

[0026] Furthermore, the vacuuming mechanism 7 includes a transfer chamber 701, a housing 702, a second motor 703, a rotating shaft 704, fan blades 705, a filter plate 706, and a vent 707. The transfer chamber 701 is fixedly connected to the surface of the top plate 6. The housing 702 is installed at the top of the transfer chamber 701. The second motor 703 is fixedly connected to the inner side of the housing 702. The rotating shaft 704 is fixedly connected to the bottom of the second motor 703. The fan blades 705 are fixedly connected to the outer surface of the rotating shaft 704. The filter plate 706 is installed inside the transfer chamber 701. A vent 707 is provided at the bottom of the transfer chamber 701. Through the configuration of the vacuuming mechanism 7, when processing aluminum alloy parts, the second motor 703 is activated. The second motor 703 drives the rotating shaft 704 to rotate at high speed, thereby causing the fan blades 705 fixed on the rotating shaft 704 to rotate at high speed as well. The high-speed rotation of the fan blades 705... A negative pressure environment is generated inside the transfer chamber 701. At this time, since the bottom of the transfer chamber 701 is connected to the external processing area through the vent 707, under the action of pressure difference, metal chips, dust and other impurities generated in the processing area are sucked into the transfer chamber 701. The filter plate 706 installed inside the transfer chamber 701 can filter and intercept the sucked impurities, preventing them from entering other parts of the dust collection mechanism 7 with the airflow, avoiding damage to key components such as the second motor 703. It also facilitates the centralized cleaning of the collected impurities. In this way, the dust collection mechanism 7 can effectively clean the chips and dust generated during the processing, maintain the cleanliness of the processing environment, reduce the impact of chip residue on the processing accuracy of aluminum alloy parts, and also help extend the service life of tooling and processing equipment, improve the safety of the production environment, and protect the health of operators.

[0027] Furthermore, three sets of filter plates 706 are arranged inside the transfer chamber 701, and the pore size of each set of filter plates 706 gradually decreases from bottom to top. Through the arrangement of filter plates 706, the three sets of filter plates 706 work together to form a highly efficient graded filtration system. The relatively large pore size of the bottom filter plate 706 can first intercept larger metal debris and dust particles, such as larger aluminum chips and coarse sand particles, to prevent them from clogging or impacting and damaging the subsequent filter plates 706. The middle filter plate 706 further filters medium-sized impurities, while the top filter plate 706, with its smaller pore size, can capture finer dust and small metal particles, ensuring that only a very small amount of tiny impurities or even almost pure air can pass through the entire filter plate 706 system. This graded filtration method greatly improves the accuracy and efficiency of filtration, effectively purifies the air in the processing area, and reduces the adverse effects of impurities on the surface quality of aluminum alloy parts.

[0028] Working principle: First, according to the specifications and installation requirements of the processing equipment's worktable, select suitable mounting holes 2 on the base plate 1, and use bolts and other connectors to firmly install the fixture on the worktable. Thanks to the symmetrical distribution of the mounting holes 2, the fixture can remain stable and evenly stressed after installation. Place the aluminum alloy part to be processed on the positioning table 4. The positioning table 4 maintains stable levelness and flatness by relying on the support feet 3 distributed in a "+" shape at the bottom, providing a precise placement foundation for the part. Then, start the first motor 503 of the adsorption mechanism 5, which drives the lead screw 50. 4. Rotation causes the lifting block 506, fitted onto the lead screw 504 and slide bar 505, to descend vertically along the lifting groove 502. This, via the lifting rod 507 and connecting rod 508, brings the suction cup 509 closer to the part surface. Then, the vacuum pump 512 is activated and the valve 511 is opened. The vacuum pump 512 creates negative pressure inside the suction cup 509, causing it to tightly adhere to the part. Because the suction cup 509 can automatically adjust its fit according to the part's contour, it can adapt to parts of different shapes and ensure positioning accuracy. During processing, it can effectively resist external forces such as cutting forces, ensuring stable part positioning. During operation, the second motor 703 of the dust collection mechanism 7 is simultaneously activated. The second motor 703 drives the rotating shaft 704 and fan blades 705 to rotate at high speed, generating negative pressure in the transfer chamber 701. Metal scraps, dust, and other impurities from the external processing area are drawn into the transfer chamber 701 through the vent 707. The impurities entering the transfer chamber 701 are then filtered sequentially by three sets of filter plates 706. Large particles are intercepted by the lower filter plate, medium-sized particles are blocked by the middle filter plate, and fine dust and small metal particles are captured by the upper filter plate. The purified air is then discharged or recycled and collected. Impurities are collected and cleaned at appropriate times. The dust collection mechanism 7 keeps the processing environment clean, reduces the impact of impurities on the processing accuracy of parts, extends the life of tooling and equipment, ensures operational safety and health, and makes the entire processing process efficient, accurate and stable, effectively improving the processing quality and production efficiency of aluminum alloy parts. The first motor 503 is model Y315S-2, the vacuum pump 512 is model FY-1H, and the second motor 703 is model YE2-132S-4. This completes the use of the aluminum alloy parts contour suction cup processing tooling.
