Description

Technical Field

[0001] This utility model relates to the field of turbine integral guide production technology, and in particular to a welding auxiliary device for welding wax molds of integral guides. Background Technology

[0002] Currently, in the production process of wax models for integral aero-engine guide vanes, due to the complex structure of the wax model, it is typically divided into several wax model units. These units are pre-fabricated and then welded together to form a complete integral aero-engine guide vane wax model. During the welding process, if manual positioning is used without welding aids, inaccurate positioning can easily occur, potentially causing the spacing between wax model units to exceed tolerances. This affects the overall dimensions of the integral aero-engine guide vane wax model and consequently the quality of the subsequent casting. Therefore, there is an urgent need for a welding aid device for wax model welding that can improve the accuracy of the integral guide vane wax model and the quality of the subsequent casting. Summary of the Invention

[0003] The purpose of this utility model is to overcome at least one deficiency of the prior art and to provide a welding auxiliary device for wax mold welding that is beneficial to improving the accuracy of the overall guide wax mold.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: According to the present application, a welding auxiliary device for welding an integral guide wax model is provided. The integral guide wax model is annular and is composed of multiple wax model units welded end to end. It includes: Base; A rotating ring is rotatably mounted on the base. The rotating ring can rotate horizontally around the axis of the rotating ring relative to the base. The rotating ring is provided with a support part for supporting the wax mold unit to be welded. A rotating disk is circumferentially mounted on the base. The rotating disk is coaxially arranged with the rotating ring and can rotate circumferentially synchronously with the rotating ring. The rotating disk is provided with a support part two for supporting the wax mold unit to be welded. The rotating disk is located inside the rotating ring and forms an annular groove with the rotating ring. A placement posture calibration mechanism includes a support body and a placement posture calibration slider. The support body is mounted on a base, and the placement posture calibration slider is slidably mounted on the support body. The placement posture calibration slider can slide vertically relative to the support body in the vertical direction. A placement posture calibration head is provided at the upper end of the placement posture calibration slider. When the placement posture calibration slider slides vertically relative to the support body, the placement posture calibration head is positioned relative to the object to be welded, which is supported by support part one and support part two. The wax model unit has a positioning position and a retraction position; when the placement posture calibration head is located in the positioning position, the placement posture calibration head extends into the annular groove, and the placement posture calibration head can contact the wax model unit to be welded supported by the first support and the second support to calibrate the placement posture of the wax model unit, so that the placement posture of the wax model unit to be welded is accurate; when the placement posture calibration head is located in the retraction position, there is a distance of one between the placement posture calibration head and the wax model unit to be welded.

[0005] The beneficial effects of this utility model are as follows: In this embodiment, an annular groove is formed between the rotating disk and the rotating ring. The placement posture calibration mechanism includes a support body and a placement posture calibration slider. The placement posture calibration head has a positioning position and a retraction position relative to the wax model unit to be welded supported by the support part one and the support part two. When the placement posture calibration head is in the positioning position, the placement posture calibration head extends into the annular groove and can contact the wax model unit to calibrate the placement posture of the wax model unit. This is beneficial to ensure that the placement posture of the wax model unit is accurate and that the positions between the wax model units to be welded are appropriate during welding, thereby improving the overall accuracy of the guide wax model. During the welding process, the placement posture calibration mechanism is used to calibrate the position and posture of the wax model unit to be welded. After calibration, the wax model unit to be welded is welded, which is beneficial to ensure that two adjacent wax model units maintain the same height. Two or more welded wax model units form a wax model unit group. When the placement posture calibration head is in the retraction position... At the same time, there is a gap between the orientation calibration head and the wax model unit, so that when the orientation calibration head is in the retraction position, the orientation calibration head and the wax model unit do not contact each other. This facilitates the removal of the positioned wax model unit and its assembly above the orientation calibration head by rotating the rotating ring and rotating disk. This facilitates the placement of the next wax model unit to be welded and the orientation calibration of the next wax model unit. During the welding process, this helps to keep the wax model unit in an accurate and appropriate position and avoids the welding operation affecting the accuracy of the overall guide wax model. Furthermore, the rotating ring and rotating disk on the base are coaxially arranged and can rotate synchronously in the circumferential direction. This keeps the wax model units on support part one and support part two in the same position relative to the rotating ring and rotating disk. This helps to keep the wax model units in an accurate and appropriate position during the welding process, thereby helping to avoid the orientation change of the welded wax model unit assembly and the breakage of the welded position of the welded wax model unit assembly.

[0006] According to one embodiment of this application, the wax model unit includes a wax model body, a first horizontal support portion and a second horizontal support portion. The first horizontal support portion is connected to one outer end of the wax model body in the radial direction, and the second horizontal support portion is connected to one inner end of the wax model body in the radial direction. The first horizontal support portion is placed on the upper side of the first support portion and supported by the first support portion, and the second horizontal support portion is placed on the upper side of the second support portion and supported by the second support portion.

[0007] In this embodiment, the first horizontal support is supported by support part one, and the second horizontal support is supported by support part two, which makes it easier to place the wax model body above the placement posture calibration head, which is conducive to accurate positioning of the wax model unit and thus helps to improve the overall guide wax model accuracy.

[0008] According to one embodiment of this application, the first support portion is an annular boss, and the second support portion is an annular boss.

[0009] In this embodiment, support part one is an annular boss one, and support part two is an annular boss two. This is beneficial to ensure that multiple wax mold units on support part one and support part two can maintain the same positioning height during the welding process, thereby improving the accuracy of the overall guide wax mold.

[0010] According to one embodiment of this application, the welding auxiliary device for welding the integral guide wax mold further includes: A circumferentially rotating positioning part is equidistantly spaced on the rotating ring; A locking mechanism is connected to the base and is used to lock the rotating ring.

[0011] In this embodiment, circumferentially spaced rotating positioning parts are provided on the rotating ring at equal intervals. After the previous wax model unit has been positioned and welded, it is easy to rotate from the current circumferential rotating positioning part to the next circumferential rotating positioning part to achieve a suitable circumferential rotation angle. This facilitates the rapid circumferential rotation of the rotating ring to an accurate position, enabling the positioning of the next wax model unit to be welded on the rotating ring. This facilitates accurate positioning of the wax model units to be welded, ensuring that the interval between each wax model unit and its two adjacent wax model units is the same during welding, thereby improving the overall accuracy of the guide wax model. Locking the rotating ring to the base with a locking mechanism helps prevent circumferential rotation of the rotating ring during welding, thus preventing the wax model units on the rotating ring from moving during welding.

[0012] According to one embodiment of this application, the welding auxiliary device for welding the integral guide wax mold further includes: A connector is provided, at least one of which is detachably connected between the rotating ring and the rotating disk.

[0013] In this embodiment, a connector is detachably provided between the rotating ring and the rotating disk, which facilitates the synchronous circumferential rotation of the rotating ring and the rotating disk. The wax model unit group that has been positioned and welded is moved out from above the placement posture correction mechanism. During the movement of the wax model unit group that has been welded, it is beneficial to avoid the wax model unit group that has been welded changing its posture and to avoid the welded position of the wax model unit group breaking.

[0014] According to one embodiment of this application, the support body includes a connecting support head and a guide protrusion connected together. The base is provided with a mounting recess groove, which communicates with the annular groove and is located on the lower side of the annular groove. The connecting support head is installed in the mounting recess groove, and the upper side of the connecting support head is flush with the bottom surface of the annular groove. The base is also provided with a clearance opening, which is connected to the mounting recess and located on the lower side of the mounting recess. The guide protrusion extends downward through the clearance opening.

[0015] In this embodiment, the connecting support head is installed in the mounting recessed groove, and the upper side of the connecting support head is flush with the bottom surface of the annular groove, so as to prevent the support body from protruding into the annular groove, thereby avoiding interference of the support body with the circumferential rotation of the rotating ring and the rotating disk.

[0016] According to one embodiment of this application, there is a distance of two between the radial sidewall of the connecting support head and the radial inner wall of the mounting recess. The welding auxiliary device for welding the wax mold of the integral guide also includes: A radial adjustment mechanism is mounted on the base, and the connecting support head is capable of radial movement under the radial drive of the radial adjustment mechanism; A locking element is used to lock the connecting support head.

[0017] In this embodiment, there is a gap of two between the connecting support head and the mounting recess, which allows for radial adjustment of the connecting support head in the radial direction. This facilitates adjusting the position of the connecting support head in the radial direction, making it easier to place the connecting support head in a suitable position in the radial direction. It also allows for adjustment of the radial position of the connecting support head according to requirements, thereby enabling the placement posture calibration mechanism to adapt to wax mold units to be welded for different sizes of integral guides. Furthermore, locking the connecting support head with a locking component helps to fix the connecting support head, which is already in a suitable position in the radial direction, and prevents the connecting support head from moving in the radial direction during the posture calibration process.

[0018] According to one embodiment of this application, the welding auxiliary device for welding the integral guide wax mold further includes: A radial adjustment reference part is disposed on the base, and the radial adjustment reference part is used to provide a reference for the adjustment distance of the connecting support head in the radial direction.

[0019] In this embodiment, by providing a radial adjustment reference part, it is beneficial for the operator to more accurately adjust the size of the distance 2 between the radial sidewall of the connecting support head and the radial inner wall of the mounting recess according to the size of the wax model unit. This is beneficial for more accurately adjusting the position of the connecting support head in the radial direction as needed, and thus for more accurately adjusting the placement posture calibration slider to a suitable position in the radial direction.

[0020] According to one embodiment of this application, the support body is provided with a vertical guide groove, and the placement posture correction slider is slidably installed in the vertical guide groove; the placement posture correction mechanism further includes: Locking mechanism two is installed on the support body. Locking mechanism two is used to lock the placement posture calibration slider, so that when the placement posture calibration head switches to the positioning position, the placement posture calibration slider is locked.

[0021] In this embodiment, the placement posture calibration slider is slidably installed in the vertical guide groove, so that the placement posture calibration slider only slides in the vertical direction. This helps to avoid the placement posture calibration slider moving in the circumferential or radial direction, and thus helps to make the placement posture of the wax model unit more accurate under the calibration effect of the placement posture calibration slider.

[0022] According to one embodiment of this application, the placement posture calibration slider is provided with a vertical height positioning hole one, and the support body is provided with a vertical height positioning hole two opposite to the vertical height positioning hole one; the locking mechanism two includes a locking pin, which is used to be inserted into the vertical height positioning hole one and the vertical height positioning hole two.

[0023] In this embodiment, the placement posture calibration head on the placement posture calibration slider is switched between a positioning position and a retraction position by the cooperation of vertical height positioning hole one, vertical height positioning hole two, and locking pin. When the locking pin is engaged with both vertical height positioning hole one and vertical height positioning hole two, the placement posture calibration head on the placement posture calibration slider is in the positioning position, which helps to keep the placement posture calibration head at a suitable height, thereby helping to ensure that the placement posture calibration heights of two adjacent wax model units are consistent. When the locking pin is not engaged with vertical height positioning hole one, the placement posture calibration head on the placement posture calibration slider is in the retraction position, which makes it easier to remove the placement posture calibration head from the underside of the wax model unit that has been positioned and welded after welding.

[0024] According to one embodiment of this application, the welding auxiliary device for welding the integral guide wax mold further includes: A vertical sliding drive mechanism is installed on the support body. The vertical sliding drive mechanism is used to drive the placement posture calibration slider to slide in the vertical direction, so that the placement posture calibration head can switch between the positioning position and the withdrawal position.

[0025] The vertical sliding drive mechanism in this embodiment enables the placement posture calibration slider to slide upward in the vertical direction, which facilitates the switching of the placement posture calibration head between the positioning position and the withdrawal position. This allows for quick switching of the placement posture calibration head to the positioning position, thereby facilitating rapid positioning of the wax model unit using the placement posture calibration head.

[0026] According to one embodiment of this application, the vertical guide slide has a lower opening, and the lower end of the support body is provided with a mounting through groove communicating with the vertical guide slide. The mounting through groove has a lower opening, and the lower end of the placement posture correction slider is directly opposite the movable avoidance through groove with a lower opening in the mounting through groove. The vertical sliding drive mechanism includes: The L-shaped rotating block is rotatably mounted on the support body and located in the first mounting slot. The L-shaped rotating block includes a first connecting edge and a second connecting edge connected together. The first connecting edge is provided with an adjustment limiting through hole. The placement posture correction slider is provided with a rotation limiting pin opposite to the adjustment limiting through hole. The rotation limiting pin passes through the adjustment limiting through hole. The first connecting edge can rotate in the first mounting slot and the movable clearance slot under the limiting action of the rotation limiting pin and the adjustment limiting through hole.

[0027] In this embodiment, the L-shaped rotating block is rotatably mounted on the support body and located in the mounting slot. When the second connecting edge is rotated, the first connecting edge can rotate at a suitable angle under the limiting action of the rotation limit pin and the adjusting limit through hole. This is beneficial for the placement posture calibration slider to slide upward a suitable distance in the vertical direction, which in turn helps to keep the placement posture calibration head at a suitable height position, thereby making the placement posture calibration height of two adjacent wax model units consistent.

[0028] According to one embodiment of this application, the orientation calibration head includes: A posture correction protrusion 1 is connected to the upper end of the posture correction slider. The posture correction protrusion 1 contacts the wax model unit to be welded, which is supported by the support part 1 and the support part 2, and constrains the placement height of the wax model unit. The second posture correction protrusion is connected to the upper end of the posture correction slider and is located on one side of the first posture correction protrusion in the circumferential direction. The second posture correction protrusion is arranged close to the rotating ring in the radial direction. The second posture correction protrusion is used to contact the wax model unit to be welded, which is supported by the first support and the second support, in the circumferential direction and to constrain the placement position of the wax model unit. The posture correction protrusion three is connected to the upper end of the posture correction slider and is arranged on the same side as the posture correction protrusion two in the circumferential direction. The posture correction protrusion three is arranged close to the rotating disk in the radial direction. The posture correction protrusion three is used to contact the wax model unit to be welded, which is supported by the support part one and the support part two, in the circumferential and radial directions and to constrain the placement position of the wax model unit. The posture correction protrusion one, the posture correction protrusion two, and the posture correction protrusion three can jointly contact the wax model unit to be welded, which is supported by the support part one and the support part two, and correct the placement posture of the wax model unit, so that the placement posture of the wax model unit to be welded is accurate.

[0029] The placement posture calibration head in this embodiment includes a posture calibration protrusion one, a posture calibration protrusion two, and a posture calibration protrusion three. The posture calibration protrusion one contacts the wax model unit to be welded and constrains the placement height of the wax model unit; the posture calibration protrusion two and the posture calibration protrusion three contact the wax model unit and constrain the placement position of the wax model unit in the circumferential direction; the three can jointly contact the wax model unit to be welded and calibrate the overall placement posture of the wax model unit, which helps to improve the accuracy of the placement posture of the wax model unit.

[0030] According to one embodiment of this application, the posture correction protrusion two includes a circumferential stop protrusion one, which is connected to the side of the posture correction protrusion two opposite to the posture correction protrusion one. The circumferential stop protrusion one near the side wall of the posture correction protrusion one is used to stop and limit the circumferential end face of the wax model unit to be welded, which is supported by the support part one and the support part two, in the circumferential direction. The top surface of the posture correction protrusion two is used to support the lower side surface of the wax model unit to be welded, which is supported by the support part one and the support part two. The posture correction protrusion three includes a circumferential stop protrusion two and a radial stop protrusion. The circumferential stop protrusion two is connected to the side of the posture correction protrusion three opposite to the posture correction protrusion one. The circumferential stop protrusion two near the side wall of the posture correction protrusion one is used to stop and limit the circumferential end face of the wax model unit to be welded, which is supported by the support part one and the support part two, in the circumferential direction. The top surface of the posture correction protrusion three is used to support the lower side surface of the wax model unit to be welded, which is supported by the support part one and the support part two. The radial stop protrusion is connected to the radial inner side of the attitude correction protrusion three and protrudes toward one side of the rotating disk. The radial stop protrusion toward the side wall of the rotating disk is used to stop and limit the radial end face of the wax model unit to be welded, which is supported by the support part one and the support part two, in the radial direction. The height of the radial stop protrusion is lower than the top surface of the attitude correction protrusion three.

[0031] In this embodiment, the circumferential stop protrusions one and two provide a stopping effect on the wax model unit, which helps to ensure that the wax model unit to be welded is in a suitable circumferential and vertical position. This improves the accuracy of the circumferential orientation of the wax model unit and helps to avoid errors caused by circumferential movement of the wax model unit during positioning and calibration. Furthermore, the radial stop protrusions stop and limit the radial end face of the wax model unit to be welded, which helps to ensure that the wax model unit is in a suitable position in the radial direction. This further helps to avoid errors caused by radial movement of the wax model unit during positioning and calibration. Attached Figure Description

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0036] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0037] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0038] This application provides a welding auxiliary device for welding integral guide wax models. The integral guide wax model is annular and is composed of multiple wax model units welded end to end. Figures 1 to 3 As shown, the welding auxiliary device for welding the wax mold of the integral guide includes: Base 1; Rotate the ring 2, which is rotatably mounted on the base 1. The ring 2 can rotate horizontally around the axis of the ring 2 relative to the base 1. The ring 2 is provided with a support part for supporting the wax mold unit to be welded. Rotating disk 3 is circumferentially mounted on base 1. Rotating disk 3 is coaxially arranged with rotating ring 2 and can rotate circumferentially synchronously with rotating ring 2. Rotating disk 3 is provided with support part 2 for supporting wax mold unit to be welded. Rotating disk 3 is located inside rotating ring 2 and forms an annular groove 7 between rotating disk 3 and rotating ring 2. The placement posture calibration mechanism 5 includes a support body 51 and a placement posture calibration slider 52. The support body 51 is mounted on the base 1, and the placement posture calibration slider 52 is slidably mounted on the support body 51. The placement posture calibration slider 52 can slide vertically relative to the support body 51 in the vertical direction. The upper end of the placement posture calibration slider 52 is provided with a placement posture calibration head. When the placement posture calibration slider 52 slides vertically relative to the support body 51 in the vertical direction, the placement posture calibration head has a positioning position and a retraction position relative to the wax model unit to be welded, which is supported by support part one and support part two. When the placement posture calibration head is in the positioning position, the placement posture calibration head extends into the annular groove 7, and the placement posture calibration head can contact the wax model unit to be welded, which is supported by support part one and support part two, and calibrate the placement posture of the wax model unit, so that the placement posture of the wax model unit to be welded is accurate. When the placement posture calibration head is in the retraction position, there is a distance of one between the placement posture calibration head and the wax model unit to be welded.

[0039] In this embodiment, as Figures 1 to 3As shown, in this embodiment, an annular groove 7 is formed between the rotating disk 3 and the rotating ring 2. The placement posture calibration mechanism 5 includes a support body 51 and a placement posture calibration slider 52. The placement posture calibration head has a positioning position and a retraction position relative to the wax model unit to be welded supported by the support part one and the support part two. When the placement posture calibration head is in the positioning position, the placement posture calibration head extends into the annular groove 7 and can contact the wax model unit to calibrate the placement posture of the wax model unit. This is beneficial to ensure that the placement posture of the wax model unit is accurate and the position between the wax model units to be welded is appropriate during welding, thereby improving the overall guide wax model accuracy. During the welding process, the placement posture calibration mechanism 5 is used to calibrate the position and posture of the wax model unit to be welded. After calibration, the wax model unit to be welded is welded, which is beneficial to ensure that two adjacent wax model units maintain the same height. Two or more welded wax model units form a wax model unit group. When the placement posture calibration head is in the retraction position, the placement posture calibration head is positioned in the retraction position. The posture calibration head and the wax model unit have a gap of 1, so that when the posture calibration head is in the retraction position, the posture calibration head and the wax model unit do not contact each other. This facilitates the removal of the positioned wax model unit and its assembly above the posture calibration head by rotating the rotating ring 2 and rotating disk 3. This facilitates the placement of the next wax model unit to be welded and the posture calibration of the next wax model unit. During the welding process, this helps to keep the wax model unit in an accurate and appropriate position and avoids the welding operation affecting the accuracy of the overall guide wax model. Furthermore, the rotating ring 2 and rotating disk 3 on the base 1 are coaxially arranged and can rotate synchronously in the circumferential direction. This ensures that the wax model units on the support part 1 and support part 2 maintain the same position relative to the rotating ring 2 and rotating disk 3. This helps to keep the wax model units in an accurate and appropriate position during the welding process, thereby helping to prevent posture changes in the welded wax model unit assembly and preventing breakage at the welded position of the welded wax model unit assembly.

[0040] Furthermore, such as Figure 1 As shown, the base 1 is supported by a vertical support beam 11.

[0041] In one embodiment of this application, the wax model unit includes a wax model body, a first horizontal support portion and a second horizontal support portion. The first horizontal support portion is connected to the outer end of the wax model body in the radial direction, and the second horizontal support portion is connected to the inner end of the wax model body in the radial direction. The first horizontal support portion is placed on the upper side of the first support portion and is supported by the first support portion, and the second horizontal support portion is placed on the upper side of the second support portion and is supported by the second support portion.

[0042] In this embodiment, the first horizontal support is supported by support part one and the second horizontal support is supported by support part two, which makes it easier to place the wax model body above the placement posture calibration head, which is beneficial for accurate positioning of the wax model unit and thus helps to improve the overall guide wax model accuracy.

[0043] One embodiment of this application, such as Figure 1 As shown, support part one is an annular boss 20, and support part two is an annular boss 30.

[0044] In this embodiment, as Figure 1 As shown, in this embodiment, the first support part is an annular boss 20 and the second support part is an annular boss 30. This is beneficial to ensure that the multiple wax mold units on the first and second support parts can maintain the same positioning height during the welding process, thereby improving the accuracy of the overall guide wax mold.

[0045] One embodiment of this application, such as Figure 1 As shown, the welding auxiliary device for welding the integral guide wax mold also includes: The circumferential rotation positioning part 21 is equidistantly arranged on the rotating ring 2 in a circumferential manner; Locking mechanism 6 is connected to base 1 and is used to lock the rotating ring 2.

[0046] In this embodiment, as Figure 1 As shown, in this embodiment, circumferentially rotating positioning parts 21 are provided at equal circumferential intervals on the rotating ring 2. After the previous wax model unit has been positioned and welded, it is convenient to rotate from the current circumferentially rotating positioning part 21 to the next circumferentially rotating positioning part 21 to achieve a suitable circumferential rotation angle. This facilitates the rapid circumferential rotation of the rotating ring 2 to an accurate position, thereby positioning the next wax model unit to be welded on the rotating ring 2. This is beneficial for the accurate positioning of the wax model units to be welded, ensuring that the interval between each wax model unit and its two adjacent wax model units is the same during welding, which in turn improves the overall accuracy of the guide wax model. Locking the rotating ring 2 to the base 1 with the locking mechanism 6 helps to prevent the rotating ring 2 from rotating circumferentially during the welding process, thus preventing the wax model units on the rotating ring 2 from moving during the welding process.

[0047] Furthermore, such as Figure 1 As shown, the circumferential rotation positioning part 21 is a circumferential rotation positioning through hole. The locking mechanism 6 is fixed on the base. The locking mechanism 6 locks the rotating ring 2 by the action of the locking connector 61 on the circumferential rotation positioning part 21.

[0048] One embodiment of this application, such as Figure 1 As shown, the welding auxiliary device for welding the integral guide wax mold also includes: The connector 4 is provided at least once, and the connector 4 is detachably connected between the rotating ring 2 and the rotating disk 3.

[0049] In this embodiment, as Figure 1 As shown, in this embodiment, the connecting member 4 is detachably connected between the rotating ring 2 and the rotating disk 3, which is beneficial to achieve synchronous circumferential rotation of the rotating ring 2 and the rotating disk 3; the wax model unit group that has been positioned and welded is moved out from above the placement posture correction mechanism 5. During the process of moving the wax model unit group that has been welded, it is beneficial to avoid the wax model unit group that has been welded changing its posture and to avoid the welded position of the wax model unit group breaking.

[0050] One embodiment of this application, such as Figures 1 to 5 As shown, the support body 51 includes a connecting support head 511 and a guide protrusion 510 connected to each other. The base 1 is provided with a mounting recess 12. The mounting recess 12 communicates with the annular groove 7 and is located on the lower side of the annular groove 7. The connecting support head 511 is installed in the mounting recess 12, and the upper side of the connecting support head 511 is flush with the bottom surface of the annular groove 7. The base 1 is also provided with a clearance opening, which is connected to the mounting recess 12 and located on the lower side of the mounting recess 12. The guide protrusion 510 extends downward through the clearance opening.

[0051] In this embodiment, as Figures 1 to 5 As shown, in this embodiment, the connecting support head 511 is installed in the mounting recess 12, and the upper side of the connecting support head 511 is flush with the bottom surface of the annular groove 7, so as to prevent the support body 51 from protruding into the annular groove 7, thereby avoiding interference of the support body 51 with the circumferential rotation of the rotating ring 2 and the rotating disk 3.

[0052] One embodiment of this application, such as Figure 3 As shown, there is a gap of two between the radial sidewall of the connecting support head 511 and the radial inner wall of the mounting recess 12; Welding auxiliary devices for welding wax molds of integral guides also include: A radial adjustment mechanism 54 is mounted on the base 1, and the connecting support head 511 can move radially under the radial drive of the radial adjustment mechanism 54; Locking element 53 is used to lock the connecting support head 511.

[0053] In this embodiment, as Figure 3As shown, in this embodiment, there is a gap of two between the connecting support head 511 and the mounting recess 12, which allows the connecting support head 511 to have radial adjustment space in the radial direction. This makes it easier to adjust the position of the connecting support head 511 in the radial direction, which is beneficial for setting the connecting support head 511 in a suitable position in the radial direction. It is also beneficial for adjusting the position of the connecting support head 511 in the radial direction according to the requirements. This makes it easier for the placement posture calibration mechanism 5 to adapt to the wax mold units to be welded of different sizes of integral guides. Furthermore, locking the connecting support head 511 by the locking member 53 helps to fix the connecting support head 511, which is already in a suitable position in the radial direction, and prevents the connecting support head 511 from moving in the radial direction during the posture calibration process.

[0054] Furthermore, such as Figures 3 to 5 As shown, the connecting support head 511 is provided with a radial adjustment mounting groove 515, and the base 1 is provided with a radial adjustment mounting through hole. The radial adjustment mechanism 54 is installed on the radial adjustment mounting groove 515 and the radial adjustment mounting through hole. It should be noted that the radial adjustment mounting through hole is not shown in this embodiment. The connecting support head 511 is also provided with a locking member mounting through groove 5111, which is beneficial to enable the connecting support head 511 to be radially adjusted and fixedly locked in the mounting recess 12 under the radial drive of the radial adjustment mechanism 54.

[0055] One embodiment of this application, such as Figure 3 As shown, the welding auxiliary device for welding the integral guide wax mold also includes: A radial adjustment reference part 13 is provided on the base 1. The radial adjustment reference part 13 is used to provide a reference for the adjustment distance of the connecting support head 511 in the radial direction.

[0056] In this embodiment, as Figure 2 and Figure 3 As shown, in this embodiment, by providing a radial adjustment reference part 13, it is beneficial for the operator to more accurately adjust the size of the distance 2 between the radial side wall of the connecting support head 511 and the radial inner wall of the mounting recess 12 according to the size of the wax model unit. This is beneficial for more accurately adjusting the position of the connecting support head 511 in the radial direction as needed, and further beneficial for more accurately adjusting the placement posture calibration slider 52 to a suitable position in the radial direction.

[0057] Furthermore, such as Figure 2 and Figure 3 As shown, the connecting support head 511 is provided with a radial adjustment positioning line 5112. When the connecting support head 511 is adjusted in the radial direction, the corresponding positional relationship between the radial adjustment positioning line 5112 and the radial adjustment reference part 13 can be used to provide a reference for the radial position of the connecting support head 511.

[0058] One embodiment of this application, such as Figure 4 and Figure 5 As shown, the support body 51 is provided with a vertical guide groove 514, and the placement posture correction slider 52 is slidably installed in the vertical guide groove 514; the placement posture correction mechanism 5 also includes: Locking mechanism two is installed on the support body 51. Locking mechanism two is used to lock the placement posture calibration slider 52, so that when the placement posture calibration head switches to the positioning position, the placement posture calibration slider is locked.

[0059] In this embodiment, as Figure 4 and Figure 5 As shown, in this embodiment, the placement posture calibration slider 52 is slidably installed in the vertical guide groove 514, so that the placement posture calibration slider 52 only slides in the vertical direction. This helps to avoid the placement posture calibration slider 52 from moving in the circumferential or radial direction, and thus helps to make the placement posture of the wax model unit more accurate under the calibration effect of the placement posture calibration slider 52.

[0060] One embodiment of this application, such as Figure 4 and Figure 5 As shown, the positioning posture calibration slider 52 is provided with a vertical height positioning hole 1 521, and the support body 51 is provided with a vertical height positioning hole 2 512 opposite to the vertical height positioning hole 1 521; the locking mechanism 2 includes a locking pin 55, which is used to be inserted into the vertical height positioning hole 1 521 and the vertical height positioning hole 2 512.

[0061] In this embodiment, as Figure 4 and Figure 5 As shown, in this embodiment, the vertical height positioning hole 521, the vertical height positioning hole 512, and the locking pin 55 are used to switch the placement posture calibration head on the placement posture calibration slider 52 between the positioning position and the retraction position. When the locking pin 55 is engaged with both the vertical height positioning hole 521 and the vertical height positioning hole 512, the placement posture calibration head on the placement posture calibration slider 52 is in the positioning position, which helps to keep the placement posture calibration head at a suitable height, and thus helps to make the placement posture calibration height of two adjacent wax model units consistent. When the locking pin 55 is not engaged with the vertical height positioning hole 521, the placement posture calibration head on the placement posture calibration slider 52 is in the retraction position, which makes it easier to remove the placement posture calibration head from the underside of the wax model unit that has been positioned and welded after welding.

[0062] One embodiment of this application, such as Figure 4 and Figure 5 As shown, the welding auxiliary device for welding the integral guide wax mold also includes: A vertical sliding drive mechanism is installed on the support body 51. The vertical sliding drive mechanism is used to drive the placement posture calibration slider 52 to slide in the vertical direction, so that the placement posture calibration head can switch between the positioning position and the withdrawal position.

[0063] In this embodiment, as Figure 4 and Figure 5 As shown, the vertical sliding drive mechanism in this embodiment enables the placement posture calibration slider 52 to slide upward in the vertical direction, which facilitates the switching of the placement posture calibration head between the positioning position and the withdrawal position. This allows for quick switching of the placement posture calibration head to the positioning position, thereby facilitating rapid positioning of the wax model unit through the placement posture calibration head.

[0064] One embodiment of this application, such as Figure 4 and Figure 5 As shown, the lower side of the vertical guide slide 514 is open, and the lower end of the support body 51 is provided with a mounting through groove 1 that communicates with the vertical guide slide 514. The lower side of the mounting through groove 1 is open, and the lower end of the orientation correction slider 52 is directly opposite the movable avoidance through groove 523 with a lower side opening in the mounting through groove 1; the vertical sliding drive mechanism includes: The L-shaped rotating block 56 is rotatably mounted on the support body 51 and located in the first mounting slot. The L-shaped rotating block 56 includes a first connecting edge and a second connecting edge connected together. The first connecting edge is provided with an adjustment limiting through hole 561. The positioning posture correction slider 52 is provided with a rotation limiting pin 57 opposite to the adjustment limiting through hole 561. The rotation limiting pin 57 passes through the adjustment limiting through hole 561. The first connecting edge can rotate in the first mounting slot and the movable avoidance through slot 523 under the limiting action of the rotation limiting pin 57 and the adjustment limiting through hole 561.

[0065] In this embodiment, as Figure 4 and Figure 5 As shown, in this embodiment, the L-shaped rotating block 56 is rotatably mounted on the support body 51 and located in the mounting through groove 1. When the second connecting edge is rotated, the first connecting edge can rotate at a suitable angle under the limiting action of the rotating limiting pin 57 and the adjusting limiting through hole 561. This is beneficial for the placement posture calibration slider 52 to slide upward a suitable distance in the vertical direction, which in turn is beneficial for keeping the placement posture calibration head at a suitable height position, so that the placement posture calibration height of the two adjacent wax model units is consistent.

[0066] Furthermore, such as Figure 4 and Figure 5As shown, the L-shaped rotating block 56 is provided with a second rotating block mounting hole 562, and the support body 51 is provided with a first rotating block mounting hole 513. The rotating block mounting pin 58 is installed on both the first rotating block mounting hole 513 and the second rotating block mounting hole 562 at the same time, so that the middle part of the L-shaped rotating block 56 is rotatably mounted on the support body 51 and located in the first mounting slot.

[0067] Furthermore, such as Figure 4 and Figure 5 As shown, the orientation calibration slider 52 is provided with a rotation limiting hole 522 for installing a rotation limiting pin 57. The rotation limiting pin 57 is rotatably installed in the rotation limiting hole 522. In addition, the vertical sliding drive mechanism in this embodiment can also adopt other vertical drive devices.

[0068] One embodiment of this application, such as Figures 3 to 5 As shown, the orientation calibration head includes: The posture correction protrusion 524 is connected to the upper end of the posture correction slider 52. The posture correction protrusion 524 contacts the wax model unit to be welded, which is supported by the support part 1 and the support part 2, and constrains the placement height of the wax model unit. The second posture correction protrusion 525 is connected to the upper end of the posture correction slider 52 and is located on one side of the first posture correction protrusion 524 in the circumferential direction. The second posture correction protrusion 525 is set close to the rotating ring 2 in the radial direction. The second posture correction protrusion 525 is used to contact the wax model unit to be welded supported by the first support and the second support in the circumferential direction and constrain the placement position of the wax model unit. The posture correction protrusion 3 526 is connected to the upper end of the posture correction slider 52 and is set on the same side as the posture correction protrusion 2 525 in the circumferential direction. The posture correction protrusion 3 526 is set close to the rotating disk 3 in the radial direction. The posture correction protrusion 3 526 is used to contact the wax model unit to be welded supported by the support part 1 and the support part 2 in the circumferential and radial directions and to constrain the placement position of the wax model unit. The posture correction protrusion 1 524, posture correction protrusion 2 525 and posture correction protrusion 3 526 can jointly contact the wax model unit to be welded supported by support part 1 and support part 2 and correct the placement posture of the wax model unit, so that the placement posture of the wax model unit to be welded is accurate.

[0069] In this embodiment, as Figures 3 to 5As shown, the placement posture calibration head in this embodiment includes a posture calibration protrusion one 524, a posture calibration protrusion two 525, and a posture calibration protrusion three 526. The posture calibration protrusion one 524 contacts the wax model unit to be welded and constrains the placement height of the wax model unit; the posture calibration protrusion two 525 and the posture calibration protrusion three 526 contact the wax model unit and constrain the placement position of the wax model unit in the circumferential direction; the three can jointly contact the wax model unit to be welded and calibrate the overall placement posture of the wax model unit, which is beneficial to improving the accuracy of the placement posture of the wax model unit.

[0070] One embodiment of this application, such as Figures 3 to 5 As shown, the second posture correction protrusion 525 includes a circumferential stop protrusion 1, which is connected to the side of the second posture correction protrusion 525 away from the first posture correction protrusion 524. The side wall of the first posture correction protrusion 1 near the first posture correction protrusion 524 is used to stop and limit the circumferential end face of the wax model unit to be welded, which is supported by the first support and the second support, in the circumferential direction. The top surface of the second posture correction protrusion 525 is used to support the lower side surface of the wax model unit to be welded, which is supported by the first support and the second support. The posture correction protrusion 3 526 includes a circumferential stop protrusion 2 and a radial stop protrusion. The circumferential stop protrusion 2 is connected to the side of the posture correction protrusion 3 526 away from the posture correction protrusion 1 524. The side wall of the circumferential stop protrusion 2 near the posture correction protrusion 1 524 is used to stop and limit the circumferential end face 1 of the wax model unit to be welded supported by the support part 1 and the support part 2 in the circumferential direction. The top surface of the posture correction protrusion 3 526 is used to support the lower side surface of the wax model unit to be welded supported by the support part 1 and the support part 2. The radial stop protrusion is connected to the radial inner side of the attitude correction protrusion 3 526 and protrudes towards the side of the rotating disk 3. The radial stop protrusion facing the side wall of the rotating disk 3 is used to stop and limit the radial end face of the wax model unit to be welded, which is supported by the support part 1 and the support part 2, in the radial direction. The height of the radial stop protrusion is lower than the top surface of the attitude correction protrusion 3 526.

[0071] In this embodiment, as Figures 3 to 5 As shown, in this embodiment, the circumferential stop protrusion one and circumferential stop protrusion two provide a stopping effect on the wax model unit, which helps to ensure that the wax model unit to be welded is in a suitable position in the circumferential and vertical directions. This helps to improve the accuracy of the circumferential orientation of the wax model unit and avoids errors caused by circumferential movement of the wax model unit during positioning and calibration. Furthermore, the radial stop protrusions stop and limit the radial end face of the wax model unit to be welded, which helps to ensure that the wax model unit is in a suitable position in the radial direction. This further helps to avoid errors caused by radial movement of the wax model unit during positioning and calibration.

[0072] Furthermore, for a wax model unit with a certain structure, the structure and position of the posture correction protrusion 1 524, posture correction protrusion 2 525 and posture correction protrusion 3 526 can be adaptively adjusted based on the posture correction head in this embodiment. This allows the radial end face of the wax model unit to be welded to be stopped and limited by the radial stop protrusion, which helps to place the wax model unit to be welded in a suitable circumferential and vertical position, thereby improving the accuracy of the circumferential posture placement of the wax model unit.
