Description

Technical Field

[0001] This invention relates to the field of investment casting technology, specifically a tooling for precisely positioning gas turbine blade investment casting assembly. Background Technology

[0002] Investment casting has very strict requirements. Even a small fluctuation can cause irreversible consequences, especially in the initial wax preparation stage. The wax preparation process involves: wax pressing, wax pattern inspection, wax pattern trimming, gating system preparation, and tree assembly. Tree assembly is a critical and core process in the whole process. Incorrect tree assembly plan, dimensions, and angles will directly affect the final result and may lead to unqualified metallurgical results in the casting, resulting in scrap.

[0003] Gas turbine blades are the core precision heat exchange and power components of a gas turbine. The verticality, height matching, and layout consistency of their assembly process directly determine the casting accuracy and the overall operational safety and stability. Currently, traditional assembly operations in the industry rely entirely on visual observation and manual fine-tuning by operators. Without the constraints of dedicated standardized positioning fixtures, human subjective judgment is highly random. Different operators and different work periods have significantly different judgment standards, which easily leads to quality defects such as blade misalignment, uneven height, and misalignment of front and rear spacing. After positioning deviations occur, it is necessary to remove the bonded blades and repeatedly reassemble and calibrate them, greatly increasing rework workload and severely reducing assembly production efficiency. At the same time, the manual positioning mode cannot guarantee the consistency of batch product accuracy, has poor process stability, and is prone to subsequent casting deformation, dimensional deviations, and scrapping problems, failing to meet the needs of mass standardized production. Summary of the Invention

[0004] To overcome the aforementioned deficiencies of the prior art, this invention provides a precision positioning fixture for assembling gas turbine blade melt molds. By setting a clamping mechanism on the fixture table to stably clamp the wax mold of the casting system, and then configuring auxiliary positioning components to abut the sides of the wax mold to be assembled, a precise and stable welding position is provided for the wax mold parts to be welded. This allows the wax mold parts in the assembly to be welded to the wax mold of the casting system using workpiece positioning instead of traditional manual visual inspection, reducing the burden of manual observation, ensuring assembly quality, reducing rework rates, improving production efficiency and the accuracy of products in the same batch, thereby solving the problems mentioned in the background art.

[0010] As a further embodiment of the present invention, the auxiliary positioning component includes an adjustment frame slidably connected to the side frame, an adjustment component is installed on the adjustment frame, and the upper and lower adjustment components are connected by a flexible hose. The adjusting component includes a telescopic vent pipe, a threaded telescopic rod, a workstation box, and a support block.

A slot is also provided at the center of the top of the workstation box.

[0011] As a further embodiment of the present invention, an ear plate is integrally provided on the top of the vertical plate on the left side, and a fixing plate is also sleeved on the telescopic vent pipe.

[0013] Compared with the prior art, the beneficial effects of the present invention are: By setting a clamping mechanism on the tooling table to stably clamp the wax model of the casting system, and then configuring auxiliary positioning components to abut the sides of the wax model to be assembled, a precise and stable welding position is provided for the wax model to be welded. This allows the wax model in the tree to be welded to the wax model of the casting system by workpiece positioning instead of traditional manual visual inspection, reducing the burden of manual observation, ensuring the quality of the tree, reducing the rework rate, improving production efficiency and the accuracy of products in the same batch. The clamping mechanism on the tooling table uses a lifting cylinder to synchronously drive the inner and outer clamping components to move. This inner support and outer frame method achieves the limiting and locking of the wax mold of the casting system. Combined with the limit lock in the outer toothed ring and auxiliary positioning component on the worktable, it prevents the quality of the mold from being affected by force deviation during the molding process. The auxiliary positioning component is equipped with an air-cooling system. An external fan generates airflow, which is then transported through pipes to enter each auxiliary component. The airflow entering the auxiliary component is finally discharged from the air outlet on the corresponding support block. This airflow corresponds to the welding position of the corresponding wax mold and can quickly remove the heat of the molten wax in the welding area, significantly shortening the solidification and setting time of the welding point. This avoids the problem of welding point displacement or detachment during the subsequent transfer of the wax tree, and specifically improves the cooling efficiency. In the air-cooled system, part of the airflow in the pipes is diverted to the high-pressure air box. The control valve is used to achieve high-pressure jetting of the airflow. This airflow is ejected when the auxiliary positioning component is reset, thereby cleaning the contact surfaces of each support block, ensuring their cleanliness, and reducing contamination of the subsequent mold.

A damping turntable 2 is provided on the top of the base 1. A support component for supporting the wax mold of the casting system is installed on the damping turntable 2. The configuration of the damping turntable 2 is to ensure that the support component can be stopped and started at any time when it is rotated and adjusted, so as to avoid the support component on it from being misaligned under the action of inertia and affecting the accuracy of the melt mold assembly tree. The side of the support component is provided with an auxiliary positioning component located on the base 1 to assist in the precise positioning of the casting mold.

The auxiliary positioning mechanism 5 and the high-pressure air box 6 are connected by pipes. The air-cooling system is designed so that the airflow can directly blow air onto the welding position, thereby concentrating the airflow to improve the cooling efficiency of the wax mold. On the other hand, it is used to blow airflow to the auxiliary positioning components in the reset state, thereby achieving a self-cleaning effect.

[0017] Please see Figures 2-5 In this embodiment of the invention, the tooling table 3 includes a disc 31 disposed on the top of the damping turntable 2.

The conical component 33 includes a conical cover 331 integrally set on the top shell wall of the disc 31. The top end of the conical cover 331 is threadedly connected to a top cover 332. The arrangement of the conical cover 331 conforms to the shape of the pouring cup in the wax mold of the gating system, and on the other hand, it has sufficient structural space inside to facilitate the assembly of the clamping mechanism 4. The threaded connection between the top cover 332 and the conical cover 331 facilitates the maintenance of its internal structure.

[0018] The clamping mechanism 4 includes a circular hole at the center of the disk 31. A lifting cylinder 41 is provided below the circular hole. The lifting cylinder 41 is fixedly connected to the bottom shell wall of the disk 31 by bolts. The output end of the lifting cylinder 41 passes through the circular hole and is equipped with a pushing assembly 44. The pushing assembly 44 is provided with an inner clamping assembly 42 and an outer clamping assembly 43. There are multiple inner clamping assemblies 42 and outer clamping assemblies 43, which are distributed along the circumferential direction. The inner clamping assembly 42 includes a notch opened on the peripheral wall of the conical cover 331, an inner support plate 421 slidably connected in the notch, a wedge block 422 slidably connected on the inner inclined surface of the inner support plate 421, and a flexible structure, such as a soft pad or an air bladder, is provided on the outer wall of the inner support plate 421, thereby reducing damage to the sprue cup of the wax mold of the gating system when providing internal support and ensuring the integrity of the product. A T-shaped guide groove is provided on the inclined surface of the inner side of the inner support plate 421, and a T-shaped slide bar is integrally provided on the inclined surface of the wedge block 422. The T-shaped slide bar is slidably connected to the T-shaped guide groove. The external clamping assembly 43 includes multiple slides formed along the circumferential direction on the top shell wall of the boss 32. The slides are connected to sliders, and clamping members 431 are installed on the top of the sliders. A bent rod 432 is fixedly connected to the side wall of the slider. The clamping member 431 includes a vertical rod 4311 fixedly connected to the top shell wall of the slider by bolts. A frame is integrally provided on the top of the vertical rod 4311. A T-shaped frame 4312 for pressing the wax mold of the gating system is slidably connected in the frame. A flexible structure, such as a soft pad or air bag, is also provided on the right shell wall of the T-shaped frame 4312, thereby reducing damage to the pouring cup of the wax mold of the gating system when clamping it on the outer wall and ensuring the integrity of the product. A threaded pin is provided on the top shell wall of the frame to limit and lock the T-shaped frame 4312 after displacement adjustment. The movement adjustment of the T-shaped frame 4312 on the frame makes it suitable for wax molds of different specifications of casting systems.

[0019] The pushing assembly 44 includes a cone 441 fixedly connected to the output end of the lifting cylinder 41. A sub-plate 442 is provided on the top of the cone 441. Multiple protrusions are provided on the peripheral wall of the sub-plate 442 along the circumferential direction. The protrusions are fixedly connected to the corresponding wedges 422 by bolts. Thus, when the lifting cylinder 41 is running, the pushing assembly 44 realizes the synchronous adjustment of multiple inner clamping assemblies 42. Multiple grooves are provided on the circumferential wall of the cone 441, and a movable block is slidably connected in each groove. The inner ends of multiple bent rods 432 are respectively fixedly connected to the corresponding movable blocks. The vertical cross section of the groove is T-shaped. To ensure the stability of the movable blocks in the groove, they are also T-shaped. When the cone 441 is raised and lowered, the movable blocks slidably connected to it can move downward due to the corresponding external clamping components 43. The downward movement of the movable blocks will cause the external clamping components 43 to move towards the center, thereby clamping the wax mold of the casting system.

[0020] Please see Figure 1 and Figures 6-9 In this embodiment of the invention, the auxiliary positioning mechanism 5 includes a carrier 51, an electric push rod 52, a sliding plate 53, a limit lock 54, a side frame 55, and an auxiliary positioning component 56. The carrier 51 includes a U-shaped seat 511 that is fixedly connected to the base 1 by bolts. The U-shaped seat 511 is provided with a guide rod assembly 512 inside. The guide rod assembly 512 is composed of two guide rods arranged symmetrically in front and behind, which are used to ensure the stability of the movement of the sliding plate 53. The top two sides of the U-shaped seat 511 are provided with receiving slots. The electric push rod 52 is set in the receiving slot on the left side, the limit lock 54 is movably connected to the receiving slot on the right side, the slide plate 53 is slidably connected to the guide rod assembly 512, the output end of the electric push rod 52 is fixedly connected to the slide plate 53, the left shell wall of the limit lock 54 is fixedly connected to the slide plate 53 by bolts, and the limit lock 54 is inserted into the external toothed ring 34 for limiting, and the side frame 55 is fixedly connected to the top shell wall of the slide plate 53 by bolts.

[0021] The auxiliary positioning component 56 includes an adjustment frame 561 slidably connected to the side frame 55. An adjustment component 562 is installed on the adjustment frame 561. The upper and lower adjustment components 562 are connected by a hose.

The adjusting component 562 includes a telescopic vent pipe 5621, a threaded telescopic rod 5622, a work station box 5623, and a support block 5624. The telescopic vent pipe 5621 is provided with vertical plates symmetrically arranged on the left and right sides. The vertical plates are fixed to the adjusting frame 561, thereby realizing the assembly of the telescopic vent pipe 5621 on the adjusting frame 561. The workstation box 5623 is fixedly connected to the output end of the telescopic vent pipe 5621, and the workstation box 5623 and the inner cavity of the telescopic vent pipe 5621 are interconnected. A slot is also provided at the center of the top of the workstation box 5623. The slot is configured to facilitate the assembly of the support block 5624.

[0022] An ear plate is integrally set on the top of the left vertical plate, and a fixed plate is also fitted on the telescopic vent pipe 5621. The threaded telescopic rod 5622 is located between the ear plate and the fixed plate. The threaded telescopic rod 5622 is composed of an inner threaded cylinder and a screw. The screw is threadedly connected to the inner threaded cylinder. The left end of the inner threaded cylinder is rotatably connected to the ear plate through a bearing, and the right end of the screw is fixedly connected to the fixed plate. By rotating and adjusting the inner threaded cylinder, the screw connected to the thread inside can move, thereby realizing the telescopic adjustment of the telescopic vent pipe 5621. The support block 5624 is fixedly connected to the top shell wall of the workstation box 5623 by bolts. The bottom end of the support block 5624 is integrally provided with an extension tube. The extension tube extends into the interior of the workstation box 5623 through a slot, so that the airflow in the workstation box 5623 can enter the extension tube. An air duct is provided above the extended pipe and located inside the support block 5624. Multiple air outlets are provided on the front and rear sides of the air duct and on the corresponding side walls of the support block 5624. The air outlets are opened at an angle upward, thereby realizing centralized air blowing at the welding position of the casting mold.

[0023] The pipeline includes a main pipe and branch pipes. The main pipe is located above the base 1 and its front end is connected to the high-pressure air box 6 and is equipped with a control valve 1. The branch pipe is set on the side frame 55, its top end is connected to the hose, and a control valve 2 is also installed on the branch pipe. The bottom end of the branch pipe is also connected to the main pipe through a hose. The configuration of control valve one and control valve two is used to control the direction of airflow, thereby achieving different functions.

[0024] The working principle of this invention is as follows: When the mold assembly tree is being manufactured, appropriate support blocks 5624 are first loaded onto the corresponding workstation box 5623 according to the shape of the mold components in the mold assembly tree to be assembled, and the threaded telescopic rod 5622 in the adjusting component 562 is adjusted so that the length of the corresponding telescopic vent pipe 5621 is adjusted, thereby completing the pre-adjustment. After pre-adjustment, the wax model of the gating system is placed on the tooling table 3. Then, the lifting cylinder 41 in the clamping mechanism 4 is activated by the external controller, causing the pushing component 44 on it to move upward. During the upward movement of the pushing component 44, the wedges 422 on the multiple inner clamping components 42 connected to the sub-plate 442 slide upward. When the wedges 422 slide upward, they squeeze the corresponding inner support plate 421 to move outward, thereby pressing and supporting the inner wall of the pouring cup in the wax model of the gating system. When the pushing component 44 moves upward, the cone 441 also moves. When the cone 441 moves upward, the multiple moving blocks connected to it move in the corresponding slide groove, thereby causing the bent rod 432 in each outer clamping component 43 to drive the corresponding slider to move inward. The clamping parts 431 on it move synchronously, thereby clamping the outer wall of the pouring cup in the wax model of the gating system, thereby achieving stable positioning of the wax model of the gating system. After the clamping mechanism 4 on the tooling table 3 completes the limiting and fixing of the wax mold of the casting system, the tooling table 3 can be manually rotated and adjusted to adjust the wax mold of the casting system loaded on it, so as to facilitate the subsequent casting mold assembly operation. Then, the electric push rod 52 and external fan in the auxiliary positioning mechanism 5 are started by the external controller. The operation of the electric push rod 52 pushes the slide plate 53 to move to the right. At this time, the limit lock 54, side frame 55 and auxiliary positioning component 56 on the slide plate 53 move to the right in sync. The limit lock 54 inserts and limits the external toothed ring 34 in the tooling table 3. The rightward movement of the auxiliary positioning component 56 causes the support block 5624 on it to move closer to the wax mold of the casting system. Finally, when the electric push rod 52 reaches the maximum mileage, the support block 5624 abuts against the wax mold of the casting system, which makes it convenient for the staff to accurately weld the molded parts to be assembled to the wax mold of the casting system. The operation of the external fan generates airflow, which is transported in the pipeline. When the slide plate 53 moves to the right, control valve one closes and control valve two opens. The airflow then enters the corresponding regulating component 562 through the pipeline. The airflow enters the corresponding support block 5624 along the telescopic vent pipe 5621. Finally, it is discharged from each vent hole in the support block 5624. The airflow discharged from the vent hole cools the welding joint of the wax mold assembly, thereby concentrating the airflow to improve the cooling efficiency of the wax mold. When welding of the casting mold part needs to be performed on other external components on the wax mold of the casting system, the external controller first closes the control valve two, then opens the control valve one, allowing the airflow to enter the high-pressure air box 6. Then, the electric push rod 52 is activated to move the slide plate 53 to the left. The leftward movement of the slide plate 53 not only removes the limit lock 54 from the tooling table 3, making it easier to rotate and adjust, but also allows the auxiliary positioning component 56 to pass through the airflow area discharged from the high-pressure air box 6 during the leftward movement of its various support blocks 5624. Under the action of the high-pressure airflow, the contact surface of the support block 5624 used to contact the casting mold part is cleaned by the airflow.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
