Description

Technical Field

[0001] This utility model relates to a casting sand core installation device, specifically to a positioning device for a compressor cylinder sand core. Background Technology

[0002] In the production process of compressor cylinder blocks, accurate positioning of the sand core is a crucial step in ensuring cylinder block quality. Traditional sand core positioning methods often suffer from insufficient precision, making it difficult to meet the high-precision production requirements of modern compressors. For example, manual positioning is prone to deviations, leading to inaccurate placement of the sand core within the cylinder block. This affects the dimensional and shape accuracy of the internal structure of the cylinder block, thereby reducing compressor performance and lifespan. Furthermore, some existing positioning devices are complex in structure and inconvenient to operate, increasing production costs and hindering production efficiency. Therefore, there is an urgent need for a compressor cylinder block sand core positioning device that can achieve high-precision positioning, is easy to operate, and is cost-effective.

By optimizing the structural design, it can achieve accurate and stable positioning of the compressor cylinder sand core, improve the sand core assembly accuracy, thereby improving the production quality and efficiency of the compressor cylinder, while simplifying the operation process and reducing production costs.

[0004] Technical Solution: The compressor cylinder sand core positioning device of this utility model mainly includes a worktable, sand core positioning blocks, a sand core moving slide structure, and a sand core inclined guide rail structure. The worktable serves as the basic support component of the entire device, providing a stable platform for the installation and operation of other components. Two sets of sand core positioning blocks are distributed on the upper left side of the worktable. A sand core moving slide structure and guide rail are provided on the right side of the worktable. Three sets of sand core positioning blocks are distributed on the moving slide structure, which can slide along the guide rail. An inclined guide rail and side sand core positioning blocks are provided on the lower left side of the worktable.

[0005] The device includes a workbench, which serves as the basic support structure of the apparatus. Sand core positioning blocks one and two are distributed on the upper left side of the workbench according to the placement position of the sand cores. A sand core moving slide structure is located on the right side of the workbench, with sand core positioning blocks three, four, and five distributed on it according to the placement position of the sand cores. A guide rail is provided between the sand core moving slide structure and the workbench, allowing the sand core moving slide structure to slide along the guide rail. An inclined guide rail structure includes side sand core positioning blocks and an inclined guide rail, with the inclined guide rail located on the left side of the workbench and side sand core positioning blocks provided on the inclined guide rail.

[0006] Furthermore, a guide limiting structure is provided between the movable slide plate structure and the guide rail. Through the cooperation of the slider and the slide groove, it can effectively ensure that the movable slide plate slides smoothly and accurately along the guide rail, thereby accurately adjusting and positioning the corresponding sand core in the horizontal direction.

[0007] Furthermore, the upper and lower sides of the mobile slide structure are equipped with auxiliary support and positioning structures, which can further fix and fine-tune the sand core after the initial positioning of the sand core, enhance the stability of the sand core on the mobile slide, and provide additional support, especially when the sand core has a complex shape and is prone to displacement, to prevent the sand core from shifting during subsequent processing.

[0008] Furthermore, a cylinder is provided on the inclined guide rail. The cylinder can drive the side sand core positioning block to slide along the inclined guide rail, thereby pushing the sand core to move upward, achieving precise vertical positioning and meeting the positioning requirements of the compressor cylinder sand core in different directions.

[0009] Furthermore, two sets of sand core positioning blocks distributed on the upper left side of the workbench are used to place the compressor valve mounting seat sand core, and the protruding part of the sand core placement part of the valve mounting seat matches the concave contact surface of the two sets of sand core positioning blocks; three sets of sand core positioning blocks on the movable slide structure are used to place the compressor cylinder chamber sand core, and the protruding part of the cylinder chamber sand core placement part matches the concave contact surface of the three sets of sand core positioning blocks; the side sand core positioning blocks in the inclined guide rail structure are used to place the piston guide sand core, and the protruding part of the piston guide sand core placement part matches the concave contact surface of the side sand core positioning blocks.

[0010] The inclined guide rail is equipped with a drive cylinder, which is used to drive the side sand core positioning block to slide along the inclined guide rail to push the sand core upward for positioning.

[0011] The first and second sand core positioning blocks are used to place the compressor valve mounting seat sand core, and the protruding part of the sand core placement area of ​​the valve mounting seat matches the concave contact surface of the first and second sand core positioning blocks; the third, fourth, and fifth sand core positioning blocks are used to place the compressor cylinder chamber sand core, and the protruding part of the cylinder chamber sand core placement area matches the concave contact surface of the third, fourth, and fifth sand core positioning blocks; the side sand core positioning block is used to place the piston guide sand core, and the protruding part of the piston guide sand core placement area matches the concave contact surface of the side sand core positioning block.

[0012] Beneficial effects: By moving the sliding plate horizontally along the guide rail and pushing the sand core vertically into position via the inclined guide rail, combined with the positioning block, the sand core can be precisely adjusted and fixed from multiple dimensions, effectively improving the positioning accuracy of the sand core and ensuring the accuracy of the internal structural dimensions of the compressor cylinder. The guide limit structure and auxiliary support positioning structure enhance the smoothness of the sliding plate during the sliding process and the stability of the sand core after positioning, reducing production quality problems caused by sand core shaking or displacement. The device has a reasonable structural design, clear functions of each component, and a simple and easy-to-understand operation process.

Figure 3 A schematic diagram of the sand core assembly process of this utility model; Figure 4 A schematic diagram of the completed sand core assembly of this utility model. Detailed Implementation

[0014] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0015] First, install workbench 1 at the predetermined position on the compressor cylinder production line. During installation, use tools such as a level to ensure the workbench is level, and secure it firmly to the ground or production equipment base using anchor bolts and other connectors, providing a stable and reliable foundation platform for subsequent sand core positioning operations.

[0016] Before positioning the compressor cylinder chamber sand core 5, check the connection between the movable slide plate structure 2 and the guide rail 24 to ensure that the guide limiting structure 26, i.e., the sliding block 261 and the slide groove 262, are not loose or obstructed by foreign objects. According to the positioning requirements of the compressor cylinder chamber sand core 5, a manual drive method is used to slowly push the movable slide plate structure 2. During the sliding process of the movable slide plate structure 2, the guide limiting structure 26 functions to ensure that the movable slide plate structure 2 moves strictly along the predetermined straight trajectory, avoiding deviation or shaking. Place the cylinder chamber sand core 5 in the corresponding positioning area of ​​the movable slide plate structure 2. At this time, the protruding part of the placement part of the cylinder chamber sand core 5 precisely matches the concave contact surfaces of positioning blocks 21, 22, and 23. When the movable slide plate structure 2 slides to the appropriate position, the cylinder chamber sand core 5 is initially positioned in the horizontal direction. Subsequently, the auxiliary support positioning structure 25 on the movable slide plate structure 2 is used to further fix the cylinder chamber sand core 5 to prevent it from moving during subsequent operations.

[0017] After the initial positioning of the compressor cylinder chamber sand core 5 is completed, the operator, wearing clean gloves (to prevent oil, dust, etc., from contaminating the sand core surface and affecting subsequent processing quality), moves the compressor valve mounting seat sand core 6 to the workbench 1. Based on the pre-set sand core positioning blocks 41 and 42 on the workbench 1, the operator manually and accurately places the valve mounting seat sand core 6 in its corresponding position. During placement, the operator can visually inspect and use simple measuring tools to ensure that the protruding part of the placement area of ​​the valve mounting seat sand core 6 closely matches the recessed contact surfaces of positioning blocks 41 and 42, ensuring the accuracy of the valve mounting seat sand core 6's position.

[0018] Before positioning the piston guide sand core 7, a comprehensive inspection of the cylinder 33 on the inclined guide rail 32 is conducted to confirm that the air pressure of the cylinder 33 is within the specified range and that the air pipe connection is secure and leak-free. Simultaneously, the surface of the inclined guide rail 32 is cleaned to ensure that no foreign objects affect the sliding of the component. The cylinder 33 drive of the inclined guide rail 32 is activated, and the piston rod of the cylinder 33 is extended by controlling the air circuit valve, pushing the component connected to the piston guide sand core 7 to slide upwards along the inclined guide rail 32. The movement trajectory of the piston guide sand core 7 is closely monitored to ensure accurate movement along the inclined guide rail 32. Through precise control of the cylinder 33 drive, the piston guide sand core 7 is pushed to the predetermined vertical height position, ensuring that the protruding part of its placement area precisely matches the recessed contact surface of the side sand core positioning block 31, achieving precise vertical positioning.

[0019] After positioning the cylinder chamber sand core 5, valve mounting seat sand core 6, and piston guide sand core 7, the remaining sand cores are placed. Operators manually place the sand cores sequentially according to their type and shape, and the installation requirements. Ensure that the protruding parts of each sand core perfectly align with the recessed contact surface of the corresponding positioning block. Keep the sand cores clean and avoid impacts during placement. For sand cores with specific installation orientation requirements, strictly follow the design specifications. After placement, thoroughly check the fit between all sand cores and the auxiliary positioning structure to ensure all sand cores are securely and accurately positioned, preparing for subsequent compressor cylinder block machining processes.

[0020] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
