Description

Technical Field

[0001] This invention belongs to the field of turbine blade wax model assembly and tree processing technology, specifically relating to a turbine blade wax model assembly and tree positioning device. Background Technology

[0002] In investment casting, wax pattern assembly welding is a crucial process connecting individual wax patterns to the gating system, and its welding quality directly affects the success or failure of subsequent shell making and casting. Turbine blades, as core hot-end components of aero-engines and gas turbines, have wax patterns characterized by complex contours, thin walls, and high dimensional accuracy requirements. Therefore, during the assembly welding process, the amount of wax oil applied to the wax pattern interfaces, the welding angle, and the positional accuracy must be strictly controlled. Otherwise, it can easily lead to wax pattern skewing, insufficient welding strength, or positioning deviations in the gating system, ultimately affecting the casting yield.

[0003] The prior art proposes a Chinese patent with publication number CN224042928U to solve the aforementioned technical problems. The technical solution disclosed in this patent document is as follows: a clamping and positioning platform for automatic assembly and welding of precision casting wax molds, including a base, a welding frame rotatably mounted on the base, a drive component one for driving the welding frame to rotate on the base, a positioning plate one horizontally mounted on the welding frame, a drive component two mounted on the welding frame, and a lifting component mounted on the base. The mold head is clamped automatically by the clamping plate one and clamping plate two, reducing the spontaneous movement of the mold head. However, this solution mainly solves the problem of clamping and fixing the tree assembly head, but the wax oil wetting depth during the welding of the wax model and the tree assembly is still difficult to control precisely. If too little wax oil is applied, the welding strength will be insufficient, and if too much wax oil is applied, a bloated wax nodule will form at the welding point, affecting the accuracy of the casting flow channel and the surface quality. At the same time, during the process of pressing the wax model interface with the tree assembly after applying wax, there is a lack of pretreatment and cooling and shaping mechanism for the interface surface, which makes it difficult to further improve the structural strength of the welded joint, thereby affecting the integrity and reliability of the wax model tree assembly in the subsequent shell making and dewaxing processes. Therefore, those skilled in the art provide a turbine blade wax model tree assembly positioning device to solve the problems mentioned in the background art. Summary of the Invention

[0004] The purpose of this invention is to provide a turbine blade wax model assembly and positioning device to improve the consistency of wax application at the wax model interface and assembly and positioning operations.

[0005] The present invention achieves the above objectives through the following technical solutions:

[0006] A turbine blade wax model assembly positioning device includes a support platform, and an adhesive component is provided on one side of the top of the support platform. The adhesive component is used to melt wax and assist in wax model welding. The bottom of the bonding component is provided with a cooling component, which is used to cool the air and promote the rapid solidification of the wax model tree after welding. A positioning component is fixedly connected to the rear side of the top of the support platform. The positioning component is used to position and install the group of trees that need to be welded. The bonding assembly includes a receiving box fixedly connected to one side of the top of the support platform. Electric heating modules are fixedly connected to both sides of the bottom of the inner wall of the receiving box. An adjustment mechanism is provided at the bottom of the inner wall of the receiving box. The bonding assembly also includes a sliding band. The adjustment mechanism is used to adjust the height of the upper surface of the sliding band.

[0007] By adopting the above technical solution, the wax block in the receiving box is heated into liquid wax oil by the electric heating module, which provides a wetting medium for the wax mold interface; at the same time, the adjustment mechanism can change the height of the upper surface of the sliding band, thereby controlling the depth of the wax mold interface immersed in the wax oil, providing a basic structural guarantee for solving the problem of inconsistent wax dipping depth and affecting the consistency of welding quality.

[0008] Preferably, the adjustment mechanism includes two positioning sleeves fixedly connected to the bottom of the inner wall of the receiving box. One of the positioning sleeves has a limit rod on its inner wall, and a first adjustment plate is slidably sleeved on the side wall of the limit rod. The other positioning sleeve is rotatably connected to a screw, which is threaded through the first adjustment plate. An auxiliary bonding module is slidably arranged in the middle of the first adjustment plate. A moving module that cooperates with the auxiliary bonding module is arranged on one side of the bottom of the inner wall of the receiving box.

[0009] By adopting the above technical solution, based on the height adjustment function, the stepless and self-locking fine adjustment of the height of the first adjustment plate is achieved through the cooperation of the screw and the limiting rod, ensuring that the adjusted position does not shift when under pressure; at the same time, the auxiliary bonding module set in the middle of the first adjustment plate can sink independently when the wax model is pressed down, thereby achieving flexible contact between the wax model interface and the sliding band while accurately controlling the wax impregnation depth, avoiding the problem of wax model deformation caused by rigid contact.

[0010] Preferably, the auxiliary bonding module includes a plurality of sliding rods that slide through the top of the first adjusting plate, wherein a first spring is sleeved on the side wall of one of the sliding rods and fixedly connected to the top of the first adjusting plate, a second adjusting plate is fixedly connected to the top of the plurality of sliding rods, a second rotating wheel is rotatably connected to both sides of the second adjusting plate, and a first rotating wheel is rotatably provided at the bottom of the plurality of sliding rods, wherein the sliding band cooperates with the first rotating wheel and the two second rotating wheels respectively.

[0011] By adopting the above technical solution, based on achieving flexible contact, the cooperation between the sliding rod and the first spring enables the second adjusting plate to automatically reset after being pressed down, facilitating continuous operation. Simultaneously, the sliding belt is tensioned between the first and second rotating wheels, forming a closed-loop belt surface that can circulate and slide. When the wax mold interface is pressed down into contact with the sliding belt, not only can wax oil be applied, but the rolling friction of the sliding belt can also perform micro-shaping of the softened wax mold interface, further solving the problem of insufficient welding contact area caused by uneven wax mold interface surfaces.

[0012] Preferably, the moving module includes a rack fixedly connected to the bottom of the inner wall of the receiving box, a ratchet fixedly connected to one end of the first rotating wheel, and a gear meshing with the rack on the side wall of the ratchet.

[0013] By employing the above technical solution, based on the closed-loop sliding of the sliding belt, the engagement of a gear with a fixed rack causes the gear to roll along the rack and drive the ratchet to rotate unidirectionally each time the sliding rod is pressed down. This, in turn, drives the first rotating wheel to intermittently advance, achieving automatic replacement of the sliding belt surface. This effectively solves the new problems of localized wax buildup, uneven heat conduction, and contamination of subsequent wax mold interfaces caused by repeated contact of the sliding belt with the same area of ​​the wax mold, ensuring the cleanliness and temperature consistency of the contact surface each time wax is applied.

[0014] Preferably, the cooling assembly includes a cooling shell fixedly connected to the bottom of the receiving box, a semiconductor cooling module fixedly passing through the middle of the top of the cooling shell, an air intake mechanism at one end of the cooling shell, and a cleaning mechanism slidably disposed at the top of the inner wall of the cooling shell.

[0015] By adopting the above technical solution, a cooling shell is set at the bottom of the receiving box, and the hot end of the semiconductor cooling module is attached to the bottom surface of the receiving box for auxiliary insulation, while the cold end is placed inside the cooling shell to generate cold air. This realizes the recovery and utilization of heat from the electric heating module and the centralized preparation of cold energy. This design solves the problems of high energy consumption of a single electric heating module and excessively long natural cooling time of the wax mold after welding, providing a stable cold source foundation for subsequent rapid air-cooling solidification.

[0016] Preferably, the air intake mechanism includes an air intake pipe that is fixedly connected to the cooling housing, and a sealing plug is slidably fitted on the inner wall of the air intake pipe, and a second spring is sleeved on the side wall of the sealing plug.

[0017] By employing the above technical solution, with the refrigeration shell equipped with a cold source, external air is introduced through the air inlet pipe for heat exchange. A second spring automatically adjusts the opening of the sealing plug based on changes in the internal temperature of the refrigeration shell, thereby controlling the air intake. This structure solves the problems of excessively rapid cold loss during the initial cooling phase and insufficient air intake after cooling stabilizes, achieved by the traditional fixed air inlet, realizing adaptive adjustment of the air intake and ensuring the continuity and stability of the cold air output.

[0018] Preferably, the cleaning mechanism includes a slide rail fixedly connected to the top of the inner wall of the cooling shell, a slide plate slidably connected to the side wall of the slide rail, a number of scrapers in a linear array at the top of the slide plate that contact the bottom of the semiconductor cooling module, a lever fixedly connected to one side of the slide plate that slides through the side wall of the cooling shell, a temperature indicator column fixedly connected to the middle of the top of the lever, a groove that cooperates with the lever on the side wall of the cooling shell, and an accordion cover provided on the inner wall of the groove.

[0019] By adopting the above technical solution, and based on adaptive air intake, a sliding plate driven by a lever slides along a rail, allowing a scraper to remove condensate from the cold end surface of the semiconductor cooling module. This effectively solves the problem of reduced cooling efficiency caused by condensation on the cold end during long-term operation. Simultaneously, the temperature indicator column visually displays the internal temperature, while the bellows cover prevents external hot air from intruding through the slide. The combination of these two features addresses the new problems of invisible internal conditions and heat loss introduced during maintenance, improving the system's maintainability and energy efficiency.

[0020] Preferably, a blower pipe is fixedly connected to the front end of the cooling shell, and a plurality of fans are provided on the inner wall of the blower pipe. A connecting plate is fixedly connected to one side of the top of the support platform, and a blower nozzle connected to the blower pipe is fixedly connected to the side wall of the connecting plate.

[0021] Using the above technical solution, after cold air is generated inside the cooling shell, it is delivered to the blower nozzle via a fan and precisely guided to the welded wax model tree nodes. The cold air not only accelerates the solidification of the wax oil, but also utilizes the cooling and contraction properties of the wax to create a "cold contraction and tightening" effect with the tree, solving the problems of insufficient adhesion strength and stress cracking or separation at the weld joint, thus significantly improving the connection reliability of the welded nodes.

[0022] Preferably, the positioning component includes a support plate fixedly connected to a support platform. A first worm gear module is disposed above the front end of the support plate. A fixed plate is fixedly connected to the output end of the first worm gear module. A second worm gear module is disposed at the front end of the fixed plate. A positioning plate is fixedly connected to the output end of the second worm gear module. An installation plate is disposed at the front end of the positioning plate. An installation block is fixedly connected to the middle of the installation plate. A plurality of balls are arranged in a circumferential array on the front end of the inner wall of the installation block. A top block that cooperates with the balls slides through the inner wall of the installation block. A third spring is sleeved on the side wall of the top block. A plurality of installation mechanisms that cooperate with the positioning plate are disposed at the front end of the installation plate.

[0023] By employing the above technical solution, and based on the cooling and enhanced welding capabilities, the first and second worm gear modules enable angle adjustment of the tree assembly in the pitch and rotation directions, while utilizing the self-locking characteristics of the worm gears to maintain posture stability. Simultaneously, a third spring within the mounting block pushes a top block, radially ejecting ball bearings to clamp the tree assembly mandrel. This structure solves the welding misalignment problems caused by inconvenient position adjustment and insecure mandrel clamping during the welding process, ensuring that tree assemblies of different specifications can be stably fixed in the optimal working posture.

[0024] Preferably, the installation mechanism includes a positioning slide rod that slides through the installation plate, a sliding adjustment block that is slidably connected to the side wall of the positioning slide rod, a fourth spring that is fixedly connected to the front end of the installation plate and sleeved on the side wall of the positioning slide rod, a limit block that is fixedly connected to the rear end of the positioning plate, a limit locking block that cooperates with the positioning slide rod that is slidably provided on the side wall of the limit block, a receiving plate that is fixedly connected to the middle of the top of the support platform, and a control module that is fixedly connected to the front side of the top of the support platform.

[0025] By adopting the above technical solution, based on fixing the tree assembly angle and clamping the mandrel, the positioning slide rod is inserted into the limiting block and automatically locked by the limiting block, realizing the rapid assembly and disassembly of the mounting plate and the positioning plate. At the same time, this locking action triggers the top block to squeeze the ball bearings, so that the tree assembly mandrel is clamped synchronously. This linkage design effectively solves the technical problem that the "clamping the mounting plate" and "clamping the tree assembly" need to be operated in separate steps in traditional devices, resulting in excessive auxiliary time. It greatly improves the efficiency of tree assembly replacement, and the ball bearing clamping method avoids scratching the mandrel surface and ensures repeatability and positioning accuracy.

[0026] The beneficial effects of this invention are as follows: 1. In this invention, the height of the upper surface of the first adjusting plate and the sliding band can be precisely controlled by the cooperation of the screw and the limiting rod in the adjusting mechanism, thereby achieving stepless adjustment of the immersion depth of the wax model interface in wax oil. This design effectively avoids the problem of inconsistent depth caused by manual wax dipping, preventing both excessive wax oil from affecting the casting accuracy and insufficient wax oil from causing insufficient welding strength, thus ensuring the consistency and reliability of the welding quality of each wax model assembly from the source.

[0027] 2. In this invention, the auxiliary bonding module achieves flexible pressing and automatic reset through a sliding rod and a first spring. Combined with the rolling friction of the sliding belt, it performs micro-shaping of the softened wax mold interface, increasing the effective bonding area. Simultaneously, the gears, racks, and ratchet work together to automatically replace the sliding belt after each press, effectively preventing localized wax buildup and uneven heat conduction, ensuring stable and clean interface treatment during continuous operation.

[0028] 3. In this invention, the hot end of the semiconductor cooling module is attached to the bottom surface of the receiving box, utilizing its heat generation to help maintain the liquid state of the wax oil, thus reducing the energy consumption of the electric heating module; its cold end is placed inside the cooling shell to generate cold air, achieving a "dual-purpose" energy optimization design. This structure effectively reduces energy waste and provides a sufficient and stable cold source foundation for the rapid solidification of subsequent welding nodes, significantly improving the overall energy efficiency level.

[0029] 4. In this invention, the second spring made of shape memory alloy in the air intake mechanism can automatically adjust the opening of the sealing plug according to the temperature change inside the cooling shell, realizing adaptive control of the air intake volume and avoiding excessive loss of cold air or insufficient air supply. Combined with the scraper and temperature indicator column in the cleaning mechanism, condensate at the cold end can be scraped off in a timely manner and the internal temperature status can be visually monitored, ensuring the long-term efficient operation of the semiconductor cooling module and reducing maintenance difficulty and troubleshooting time.

[0030] 5. In this invention, the fan delivers cold air from the cooling shell to the blower nozzle via the blower pipe, and precisely guides it to the newly welded wax model tree node. Rapid cooling not only significantly shortens the wax solidification time, but also utilizes the characteristics of wax material cooling and shrinking to form a "cold contraction and tightening" effect, resulting in a stronger mechanical locking force between the wax model and the tree, significantly improving the tensile strength and stress crack resistance of the welded node.

[0031] 6. In this invention, the positioning component achieves pitch and rotation angle adjustment through the first and second worm gear modules, and maintains stable posture by relying on the self-locking characteristics of the worm gears, adapting to different specifications of tree assembly. In the installation mechanism, while the positioning slide rod is inserted into the limiting block and locked by the limiting block, the top block is triggered to push the ball to clamp the tree assembly mandrel, realizing the simultaneous completion of "installation plate locking" and "tree assembly clamping", greatly shortening the replacement auxiliary time and effectively protecting the mandrel surface from damage.

[0034] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0035] Example: Figure 1 - Figure 13As shown, a turbine blade wax model assembly positioning device includes a support platform 4. An adhesive component 1 is provided on one side of the top of the support platform 4. The adhesive component 1 is used to melt wax and assist in wax model welding. A cooling component 2 is provided at the bottom of the adhesive component 1. The cooling component 2 is used to cool the air and promote the rapid solidification of the wax model assembly after welding. A positioning component 3 is fixedly connected to the rear side of the top of the support platform 4. The positioning component 3 is used to position and install the assembly to be welded. A control module 5 is fixedly connected to the front side of the top of the support platform 4 to coordinate the working sequence of each component.

[0036] like Figure 1 - Figure 5 As shown, the bonding component 1 includes a receiving box 101 fixedly connected to one side of the top of the support platform 4. Electric heating modules 103 are fixedly connected to both sides of the bottom of the inner wall of the receiving box 101, which are used to heat and melt the wax block in the receiving box 101. An adjustment mechanism is provided at the bottom of the inner wall of the receiving box 101, which is used to adjust the height of the upper surface of the sliding belt 106.

[0037] It should be noted that the wax block is heated and melted using the heating module 103. After the tree assembly is installed on the positioning component 3, the operator can dip the welding interface of the wax model into liquid wax oil and press it to weld it onto the corresponding node of the tree assembly. Because a layer of wax oil is evenly adhered to the sidewall of the wax model interface, the effective contact area and wetting effect between the wax model and the tree assembly are significantly increased. Therefore, the turbine blade wax model can be more firmly fixed to the tree assembly, effectively preventing accidental detachment during subsequent shell making or transportation.

[0038] It should be further explained that wax blocks of the same material as the wax model and the tree assembly are placed in the receiving box 101 to ensure that the melted wax oil has the same chemical composition and shrinkage rate as the base material, thereby improving the material compatibility between the wax model and the tree assembly and avoiding poor interface bonding or uneven shrinkage due to material differences.

[0039] like Figure 1 - Figure 5 As shown, in order to improve the control accuracy of the immersion depth of the interface when dipping in wax oil, the adjustment mechanism includes two positioning sleeves 102 fixedly connected to the bottom of the inner wall of the receiving box 101. One of the positioning sleeves 102 is provided with a limit rod 108 on its inner wall, and a first adjustment plate 105 is slidably sleeved on the side wall of the limit rod 108. The other positioning sleeve 102 is rotatably connected with a screw 104 that is threaded through the first adjustment plate 105. An auxiliary bonding module is slidably provided in the middle of the first adjustment plate 105, and a moving module that cooperates with the auxiliary bonding module is provided on one side of the bottom of the inner wall of the receiving box 101.

[0040] It should be noted that the height of the first adjusting plate 105 within the receiving box 101 can be precisely adjusted by rotating the screw 104. When the wax mold interface is pressed down, the auxiliary bonding module will sink accordingly, and its sinking stroke is limited by the set height of the first adjusting plate 105, thereby precisely controlling the immersion depth of the interface sidewall each time wax is applied. This avoids the weld joint from becoming bloated due to excessive wax application, which would affect the accuracy of the casting flow channel; and it also prevents insufficient wax application from resulting in insufficient weld contact surface, which would weaken the structural strength.

[0041] like Figure 1 - Figure 5 As shown, the auxiliary bonding module includes several slide rods 111 that slide through the top of the first adjustment plate 105. One of the slide rods 111 has a first spring 110 fixedly connected to the top of the first adjustment plate 105 on its side wall. The first spring 110 is used to provide a reset driving force after the pressing operation is completed, so as to ensure that the slide rod 111 and the components connected thereto can quickly return to the initial position, which facilitates continuous operation and avoids the wax from solidifying and sticking in the non-working position.

[0042] like Figure 1 - Figure 5 As shown, to improve the welding strength of the turbine blade wax model and the assembly tree, the bonding component 1 also includes a sliding band 106. The surface of the sliding band 106 is rough. When the wax model interface is pressed down, it will push the sliding band 106 to generate relative movement. With the help of its rough surface, and the wax model interface gradually softening under the heat conduction of the wax oil, the friction of the sliding band 106 can perform appropriate micro-plastic deformation on the interface surface, increasing the micro-roughness of the contact surface, thereby forming a stronger mechanical interlocking and adhesive synergy effect during subsequent welding.

[0043] It should be noted that a sliding band 106 is provided on the side wall of the second adjusting plate 112. This sliding band 106, through heat conduction from the wax oil in the receiving box 101, has a surface temperature between the wax oil temperature and room temperature (significantly higher than room temperature but lower than the wax oil temperature). This temperature range utilizes the characteristics of wax as an amorphous material, causing it to reach above its glass transition temperature upon contact, becoming soft and highly adhesive. Welding at this temperature allows for more complete interfacial diffusion and adhesion, thereby improving the overall structural strength of the tree assembly and the product qualification rate.

[0044] like Figure 1 - Figure 5 As shown, in order to prevent wax residue from remaining on the surface of the sliding strip 106 due to prolonged local contact with the same position and to ensure a uniform surface temperature distribution, a second adjusting plate 112 is fixedly connected to the top of several sliding rods 111. A second rotating wheel 113 is rotatably connected to both sides of the second adjusting plate 112. A first rotating wheel 109 is rotatably provided at the bottom of several sliding rods 111. The sliding strip 106 cooperates with the first rotating wheel 109 and the two second rotating wheels 113 respectively.

[0045] It should be further explained that both second rotating wheels 113 and the first rotating wheel 109 are gear-shaped structures, and the inner wall of the sliding belt 106 has a toothed structure that meshes with them. This gear-belt mating design effectively prevents slippage caused by wax oil impregnation, ensuring the accuracy and stability of transmission. When the first rotating wheel 109 rotates, the sliding belt 106 slides synchronously, thereby bringing the clean, unheated belt surface out of the receiving box 101. On the one hand, this allows the wax oil to continuously impregnate the belt surface to maintain its temperature, avoiding localized overcooling that would lead to poor softening; on the other hand, residual wax lumps adhering to the belt surface will remelt and be recycled after being transferred to the wax oil surface, improving material utilization.

[0046] like Figure 1 - Figure 5 As shown, in order to achieve automated driving of the above sliding process, the moving module includes a rack 107 fixedly connected to the bottom of the inner wall of the receiving box 101, a ratchet 114 fixedly connected to one end of the first rotating wheel 109, and a gear 115 that meshes with the rack 107 is provided on the side wall of the ratchet 114.

[0047] It should be noted that when the slide bar 111 is pressed down, the first rotating wheel 109 and gear 115 descend synchronously. Gear 115, driven by its meshing with the fixed rack 107, rotates, which in turn drives the ratchet 114 to rotate. The ratchet 114 drives the first rotating wheel 109 to rotate in one direction, causing the sliding belt 106 to slide a fixed distance on the second adjusting plate 112. When the slide bar 111 returns to its original position under the action of the first spring 110, gear 115 rotates in the opposite direction, ratchet 114 is disengaged, and the first rotating wheel 109 remains stationary. This achieves intermittent feeding of "one press, one step," effectively preventing the same area of ​​the belt surface from being reused repeatedly.

[0048] like Figure 1 - Figure 3 , Figure 6 - Figure 8 As shown, in order to reduce energy consumption and improve energy utilization, the cooling component 2 includes a cooling shell 201 fixedly connected to the bottom of the receiving box 101. A semiconductor cooling module 205 is fixedly inserted through the middle of the top of the cooling shell 201. Its hot end is in close contact with the bottom of the receiving box 101, and its heat generation helps to maintain the wax oil liquid state, reducing the load on the electric heating module 103. Its cold end is placed inside the cooling shell 201 to generate cold energy and provide a rapid cooling air source for subsequent welding parts, realizing the energy efficiency optimization design of "one device for two purposes".

[0049] like Figure 1 - Figure 3 , Figure 6 - Figure 8As shown, in order to protect the interior of the cooling housing 201 from dust and assist in fault diagnosis, an air intake mechanism is provided at one end of the cooling housing 201. The air intake mechanism includes an air intake pipe 202 that is fixedly connected to the cooling housing 201. A sealing plug 211 is slidably fitted on the inner wall of the air intake pipe 202, and a second spring 212 is sleeved on the side wall of the sealing plug 211.

[0050] It should be noted that the second spring 212 is made of shape memory alloy. The second spring 212 deforms with the temperature change inside the cooling shell 201 to move the sealing plug 211 and adjust the opening of the air inlet pipe 202; the temperature indicator column 209 is used to display the temperature change inside the cooling shell 201, so that the operator can judge the operating status of the device.

[0051] like Figure 1 - Figure 3 , Figure 6 - Figure 8 As shown, to improve the operational stability of the semiconductor cooling module 205 and facilitate maintenance, a cleaning mechanism is slidably provided at the top of the inner wall of the cooling housing 201. The cleaning mechanism includes a slide rail 206 fixedly connected to the top of the inner wall of the cooling housing 201. A slide plate 204 is slidably connected to the side wall of the slide rail 206. The top of the slide plate 204 has a number of scrapers 208 arranged in a linear array that contact the bottom of the semiconductor cooling module 205. A lever 210 is fixedly connected to one side of the slide plate 204 and slides through the side wall of the cooling housing 201. A temperature indicator column 209 is fixedly connected to the middle of the top of the lever 210. A groove is opened on the side wall of the cooling housing 201 to cooperate with the lever 210. A bellows cover is provided on the inner wall of the groove. The bellows cover can prevent external dust from entering and block external heat from being introduced through the groove gap, thus avoiding cooling loss.

[0052] It should be noted that when the cooling efficiency of the cold end surface of the semiconductor cooling module 205 is affected by the accumulation of condensate, the operator can manually move the lever 210 to drive the scraper 208 to reciprocate along the slide rail 206 to scrape off the condensate film, keep the cold end surface dry, and restore the high-efficiency heat exchange capacity.

[0053] It should be further explained that the temperature indicator column 209, fixedly connected to the center of the top of the lever 210, is used to display the temperature changes inside the cooling housing 201. The temperature indicator column 209 is a transparent column with good thermal conductivity, embedded with a temperature indicator color bar, and has scale lines on its surface, which can reflect the internal temperature changes of the cooling housing 201. Since the cooling housing 201 needs to be wrapped with insulation material when the semiconductor cooling module 205 is in use, it is not possible to directly observe the internal condition. The temperature indicator column 209 provides a non-destructive visualization window of the internal status, making it convenient to observe the operating status of the device.

[0054] like Figure 1 - Figure 3 , Figure 6 - Figure 8As shown, a blower pipe 203 is fixedly connected to the front end of the cooling shell 201. Several fans 207 are installed on the inner wall of the blower pipe 203. A connecting plate 7 is fixedly connected to one side of the top of the support platform 4. A blower nozzle 8 connected to the blower pipe 203 is fixedly connected to the side wall of the connecting plate 7. The cold air can not only accelerate the solidification of wax oil and improve production efficiency, but more importantly, the wax oil will shrink appropriately during the rapid cooling process, thereby forming a stronger clamping force on the wood (i.e., the "cold shrinkage clamping" effect) and improving the tensile strength of the welded joint.

[0055] like Figure 1 , Figure 9 - Figure 13 As shown, the positioning component 3 includes a support plate 301 fixedly connected to the support platform 4. A first worm gear module 302 is disposed above the front end of the support plate 301. A fixing plate 303 is fixedly connected to the output end of the first worm gear module 302. A second worm gear module 304 is disposed at the front end of the fixing plate 303. A positioning plate 305 is fixedly connected to the output end of the second worm gear module 304. Both the first worm gear module 302 and the second worm gear module 304 adopt a worm gear self-locking structure, which can realize stepless adjustment of pitch angle and rotation angle respectively. The joint is adjusted and the angle is kept constant by the self-locking characteristic of the worm gear to avoid the tree group from shifting due to gravity or external force during the welding process. The front end of the positioning plate 305 is provided with a mounting plate 306. The middle of the mounting plate 306 is fixedly connected with a mounting block 307. The front end of the inner wall of the mounting block 307 has a number of balls 309 arranged in a circular array. The inner wall of the mounting block 307 has a top block 310 that cooperates with the balls 309. The side wall of the top block 310 is fitted with a third spring 308. The front end of the mounting plate 306 is provided with a number of mounting mechanisms that cooperate with the positioning plate 305.

[0056] like Figure 1 , Figure 9 - Figure 13As shown, the installation mechanism includes a positioning slide rod 314 that slides through the mounting plate 306. A sliding adjustment block 313 is slidably connected to the side wall of the positioning slide rod 314. A fourth spring 315, which is fixedly connected to the front end of the mounting plate 306, is sleeved on the side wall of the positioning slide rod 314. A limit block 311 is fixedly connected to the rear end of the positioning plate 305. A limit locking block 312 that cooperates with the positioning slide rod 314 is slidably provided on the side wall of the limit block 311. A receiving plate 6 is fixedly connected to the top center of the support platform 4. During the installation process, the operator moves the mounting plate 306 toward the positioning plate 305, so that the positioning slide rod 314 is inserted into the limit block 311, and the limit locking block 312 automatically locks the groove of the positioning slide rod 314, thus completing the quick locking. Simultaneously, the pushing action of the mounting plate 306 compresses the third spring 308 and pushes the top block 310 forward. The top block 310 radially pushes the ball bearing 309 out of the inner wall of the mounting block 307, thereby clamping the tree assembly mandrel inserted into the center hole of the mounting block 307. This linkage design achieves the simultaneous completion of "mounting plate locking" and "tree assembly clamping", greatly shortening the clamping auxiliary time, and the ball bearing clamping method causes minimal damage to the mandrel surface.

[0057] It should be noted that, in the operation of this turbine blade wax model assembly positioning device, the operator first inserts the mandrel to be welded into the mounting block 307, then pushes the mounting plate 306 towards the positioning plate 305, causing the positioning slide rod 314 to insert into the limiting block 311 and be automatically locked by the limiting block 312. This action simultaneously triggers the top block 310 to move forward, pushing the ball 309 radially out, thereby achieving a stable clamping of the mandrel. After the assembly is completed, according to the specifications of this batch of wax models, the operator drives the first adjusting plate 105 to slide up and down along the limiting rod 108 by rotating the screw 104, precisely adjusting the height position of the upper surface of the sliding strip 106, thereby setting the predetermined depth for the wax model interface to be dipped in wax oil. At the same time, the electric heating module 103 heats the wax block in the receiving box 101, melting it into liquid wax oil, while the hot end of the semiconductor cooling module 205 simultaneously supplements heat to the bottom of the receiving box 101 to help maintain the temperature of the wax oil. After preparation, the welding operation begins. The operator holds the turbine blade wax model and presses its welding interface downwards onto the surface of the sliding band 106 on the second adjusting plate 112. The sliding rod 111 overcomes the elastic force of the first spring 110, causing the second adjusting plate 112 and the sliding band 106 to sink synchronously until they reach the height limited by the first adjusting plate 105. At this point, the sidewall of the wax model interface is soaked in wax to a predetermined depth. During this pressing process, the gear 115 rolls along the fixed rack 107, driving the first rotating wheel 109 to rotate unidirectionally via the ratchet 114. This causes the sliding band 106 to slide a certain distance on the second adjusting plate 112, achieving automatic step-by-step replacement of the band surface and ensuring that a clean and uniformly heated band surface area is used for each wax application. At the same time, the rough surface of the sliding band 106 produces a small amount of frictional shaping on the heated and softened wax model interface, increasing the effective contact area for subsequent welding. The operator then quickly moved the wax mold dipped in wax oil to the positioning component 3, aligned it with the predetermined welding node on the assembly tree, and pressed it together. The liquid wax oil formed a uniform adhesive layer at the interface. After welding, the system enters a rapid cooling and resetting phase. The operator starts the fan 207 via control module 5, delivering cold air prepared by the cold end of the semiconductor cooling module 205 within the cooling shell 201 through the air duct 203 to the air nozzle 8. This air is precisely blown onto the newly welded joint, causing the wax to solidify rapidly. The cooling and contraction of the wax creates a "cold contraction and tightening" effect, significantly improving the connection strength of the welded joint. The position of the welded wax model is adjusted by the first worm gear module 302 and the second worm gear module 304. The worm gear self-locking structure maintains the optimal working posture of the tree assembly in the pitch and rotation directions, facilitating the operator to sequentially weld the remaining wax models on the same tree assembly. After all wax models are welded, the operator releases the locking block 312 from the positioning slide rod 314, removes the mounting plate 306 along with the mounting block 307 and the welded wax model tree assembly, and proceeds to the next shell-making process, thus completing one full work cycle.
