Description

Technical Field

[0001] This utility model relates to the technical field of sand core assembly equipment, and in particular to a large cylinder block automatic line cylinder core split assembly sand core device. Background Technology

[0002] Large cylinder blocks have complex internal structures, and the casting production of the internal cavity requires the assembly of various sand cores, including the core for the cylinder head, cylinder barrel, camshaft, water jacket, side plate, and small oil passage. These sand cores are heavy, with the cylinder barrel core generally being the heaviest. If the cylinder barrel core can be parted as a whole, the sand core can be produced using an automated core-making center, and then gripped and removed using a robotic arm. After deburring with a deburring fixture, it is then coated. However, if the cylinder barrel core has a complex shape and cannot be parted as a whole, it must be produced individually, assembled, and then coated. The coating process is complex and cannot be directly produced using a core-making center. Instead, individual cylinder sand cores are produced and then manually assembled into a whole and bolted together. A rotating coating hanger is then used for coating, and excess coating is drained before the cores are transferred to a surface drying furnace for drying. This process is not only time-consuming and labor-intensive but also carries various risks. The degree of damage to the sand cores during transportation, assembly, and rotating coating is uncontrollable, which will inevitably have a significant impact on the surface shape of the produced castings.

[0003] The existing technology, application number CN117655285A, describes a multi-layer sand core assembly device and method, which requires a specific workstation to position the sand core, and the turntable occupies a large area. In addition, it requires four handling operations before assembly, which consumes a lot of time and is inefficient.

[0004] Therefore, it is necessary to design a large-scale automatic cylinder core assembly and sand core device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a large-scale cylinder block automatic cylinder core split assembly sand core device to overcome the above-mentioned shortcomings of the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A large-scale automatic cylinder core assembly sand core device includes a working platform, characterized in that: it further includes a first linear slide rail and a second linear slide rail arranged parallel to each other on the working platform; a first placement platform slidably mounted on the first linear slide rail via a slider; a first drive unit placed on the working surface for driving the first placement platform to move; a second placement platform and a third placement platform respectively mounted on the second linear slide rail via sliders; a second drive unit for driving the second placement platform and the third placement platform to move; a fourth placement platform disposed on the working platform; and limiting components disposed on the working platform for limiting the first placement platform, the second placement platform, and the third placement platform respectively. Guide blocks are respectively provided at the bottom of one side of the second placement platform and the third placement platform, and the guide blocks of the two platforms are connected to each other by a connecting rod.

[0008] Preferably, the second drive unit is interconnected with the third placement platform via a connecting block.

[0009] Preferably, the second placement platform is disposed between the first placement platform and the third placement platform, and the fourth placement platform is disposed between the first placement platform and the second placement platform via a mounting base.

[0018] Reference Figures 1 to 3 A large cylinder block automatic cylinder core split assembly sand core device includes a working platform 1, a first linear slide rail 11 and a second linear slide rail 12 placed on the working platform and arranged parallel to each other, a first placement platform 2 slidably mounted on the first linear slide rail by a slider, a first drive unit 3 placed on the working table and used to drive the first placement platform to move, a second placement platform 41 and a third placement platform 4 respectively mounted on the second linear slide rail 12 by sliders, a second drive unit 5 driving the second placement platform and the third placement platform to move, a fourth placement platform 6 disposed on the working platform, and limiting components 7 disposed on the working platform to limit the first placement platform, the second placement platform and the third placement platform respectively.

[0019] The bottom of one side of the second and third placement platforms are respectively provided with guide blocks 5, and the guide blocks of the two are connected to each other by a connecting rod 51; the second drive unit is connected to the third placement platform by a connecting block, and the guide blocks can move along the connecting rod;

[0020] The second placement platform is positioned between the first placement platform and the third placement platform. The fourth placement platform is positioned between the first placement platform and the second placement platform via a mounting base. The fourth placement platform does not move and serves as the reference for the installation of the other three sets of placement platforms.

[0021] Each of the first, second, third, and fourth placement platforms is equipped with a sand core placement positioning block 21 for limiting the sand core; different sand core structures are placed on different platforms by a transport mechanism and fixed by the sand core placement positioning block 21.

[0022] To ensure the accuracy of sand core assembly, the positions of the first, second, and third placement platforms need to be repositioned to ensure that each sand core component can be aligned after movement, thus guaranteeing assembly accuracy. The limiting component 7 includes a first limiting block module 71 located at the left end of the first linear slide rail, a first placement platform limiting module 72 located near the first limiting block module 71 and positioned on both sides of the first linear slide rail, a third placement platform limiting module 73 located at the right end of the second linear slide rail and positioned on both sides, a second placement platform limiting module 74 positioned on both sides of the middle of the second linear slide rail, and a second limiting module 74 located on both sides of the second linear slide rail. Block module 75; The first limiting block module is used to limit the movement of the first placement platform and prevent the drive from moving out of the slide rail. When the first placement platform moves to the side, the first placement platform limiting modules 72 on both sides are adjusted to limit the two sides of the first placement platform and limit its position, thus adjusting the position of its placement platform; Similarly, when the third placement platform moves to the end, the third placement platform limiting module 74 limits and adjusts it. The second limiting block module 75 is used to limit the sliding position of the second placement platform, preventing it from moving close to the third placement platform, so that it cannot cooperate with the second placement platform limiting module 74 for limiting. The position of the second placement platform is limited by the second placement platform limiting module 75.

[0023] In order to effectively control each drive unit, a solenoid valve device 8 is also provided on the working platform. The solenoid valve device is connected to the equipment and controls the air intake and exhaust of the cylinder.

[0024] In order to sense whether the product is installed in place, a device sensing device 9 is also provided on the side of the work platform 1; the device sensing device senses whether the product is installed in place, as well as the level adjustment, etc.

[0025] In order not to affect the travel of each platform, the third placement platform is smaller than the second placement platform, and the second limiting block module is not on the formation path of the third placement platform;

[0026] In this implementation, the solenoid valve device 8 controls two sets of drive units, causing the two cylinders on the assembly fixture to be in the ejected state. At this time, the first placement platform is pushed forward, opening the first placement table limiting module 72 and placing it on both sides of the first placement platform. The first placement platform is in contact with the first limiting module 71, restricting the position of the first placement platform. The first placement table limiting module is opened to position and fix the first placement platform. When the placement work platform moves when the robot places the sand core, the dier drive unit drives the third placement platform to move to the right along the second linear slide rail, contacting the end limiting block to restrict its position. The third placement platform is then opened to position and fix it. The placement platform limiting module restricts its position to prevent movement during placement. Since the second and third placement platforms are connected by a linkage, the movement of the third placement platform to the end will cause the second placement platform to move and come into contact with the second limiting module 75. The second limiting block module restricts the second placement platform, and the second placement platform limiting module 74 is opened to fix the position of the second placement platform. Then, the core-making center robotic arm clamping device places the four produced sand cores onto the assembly fixture in sequence. The number of times the equipment sensing device detects the placement of the four sand cores determines that the placement of the four sand cores is complete; the initial placement of the top and sand cores is completed.

[0027] Then, through the control of the solenoid valve device, the two sets of drive units are driven to be in a closed state. At this time, with the sand core of the fourth placement platform as the center, the first placement platform is driven to move closer to the fourth placement platform 6, so that the two are combined. Simultaneously, the third placement platform moves to the left and moves closer to the fourth placement platform 6, so that the two are close together and combined. The third placement platform continues to push, driving the second placement platform to move synchronously and move closer to the fourth placement platform. At this point, the four sets of platforms 1, 2, 3, and 4 are close together, so that the four sets of sand cores are combined together. The sand cores are then locked together by bolt structure or other connection structure. After being picked up by a robot arm and clamped as a whole, they are soaked, drained, and placed in a circulating tray to enter the surface drying oven for drying.

[0028] The advantages of this utility model are that, by setting different slide rails and using two sets of drive units, the assembly can be completed in three steps. Compared with the prior art, this utility model has fewer steps, simpler process, lower equipment cost, reduced labor input, saves time and effort, and effectively improves product quality.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
