Description

Technical Field

[0001] The present invention relates to the technical field of precision casting wax pattern assembly and alignment, and relates to a large thin-walled wax mold splicing and alignment device and method. Background Art

[0002] Wax pattern splicing and alignment is an important link before the development process of precision casting of castings. During the process of splicing and aligning wax patterns, the wax mold is usually cleaned manually, and then the wax mold is positioned, aligned, spliced, and the dimensions are corrected. The manual wax mold splicing and alignment method is only applicable to some wax mold structures with simple structures, large wall thickness dimensions, fewer core molds and oil path cores, and relatively small deformation amounts. When performing splicing and alignment of large thin-walled wax molds, due to the large external dimensions and irregular structures, and at the same time the main wall thickness is relatively thin, the thin-walled part of the main wax mold is easily damaged during the manual alignment and splicing process; in addition, due to the irregular structure of the wax group, the center of gravity shifts, and the wax mold structure is easily deformed or even knocked and damaged during handling and placement; in addition, when multiple groups of wax molds are spliced, the cumulative error will be larger. Especially in the splicing of thin-walled parts, there are phenomena of excessive stretching and extrusion of the wax mold, resulting in serious deformation of the main body of the wax mold, it is difficult to guarantee the overall assembly accuracy, and the splicing work efficiency is low. Subsequently, problems such as out-of-tolerance casting dimensions, uneven wall thickness, poor mechanical properties, and even scrapping will occur. Summary of the Invention

[0015] Step 2: Pull open the reset mechanism and the conforming block, place the wax group to be spliced in the conforming positioning groove of the adjustment platform, make the positioning hole of the adjustment platform coincide with the limiting hole of the support column by adjusting the coordinate adjustment mechanism, and use the positioning pin to connect to realize the positioning of the adjustment platform, so as to realize the preliminary rough splicing between the wax groups to be spliced, and then close the reset structure and fix it with the limiting block;

[0042] To make the objectives, technical solutions, and advantages of the present invention more clear, the following will describe the technical solutions in the embodiments of the present invention in more detail in combination with the embodiments of the present invention. In the examples, the same or similar reference numerals represent the same or similar components or components with the same or similar functions throughout. The described embodiments are some embodiments of the present invention, rather than all embodiments. The following embodiments described by reference are exemplary and are intended to explain the present invention and should not be construed as a limitation to the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention. The following will be described in detail in combination with the embodiments of the present invention.

[0043] An embodiment of the present invention provides a large-sized thin-walled wax mold splicing and alignment device. As Figure 1 shown, the device includes: a movable splicing platform 1, a coordinate adjustment platform 2, a deformation adjustment mechanism 3, a height limiting plate 4, a re-inspection conforming template 5, a reference fixed support platform 6, and a positioning support column 7.

[0044] Exemplarily, the coordinate adjustment platform 2 and the reference fixed support platform 6 are fixed to the movable splicing platform 1 by screws. As Figure 1 shown, for the left and right parts of the movable splicing platform 1, the height difference between the movable splicing platform 1 and the reference fixed support platform 6 is set according to the height of the wax group to be spliced. The splicing and alignment reference is the wax group placed in the reference fixed support platform 6. Then, a height limiting plate is selected at the flat position of the wax mold for height direction limiting of the wax mold. Then, the adjustment knobs 20 of the coordinate adjustment mechanism are respectively adjusted to make the theoretical position holes of the adjustment platform 19 coincide with the theoretical position holes of the support column 11, and are connected by the positioning pin holes 12 to achieve rough positioning of the wax group to be spliced. According to the shape of the wax group to be spliced, two deformation adjustment mechanisms 3 are respectively fixed to the working surface of the adjustment platform 19 at positions, and the size alignment of the wax mold to be spliced is achieved through the opening and closing reset mechanism 24 and the fine adjustment mechanism 26. The position of the re-inspection conforming template 5 is set according to the position of the wax mold splicing seam, and by observing the coincidence degree between the template surface and the surface of the wax mold seam, the wax group is repeatedly adjusted in micro size.

[0045] Coordinate adjustment platform 2: By adjusting the button 20 to drive the lead screw 18, the bottom plate 15, the transition plate 16, and the working panel 17 generate relative position movements, and are fixed by the locking nut 21 after reaching the theoretical position. The brackets of the bottom plate 15, the transition plate 16, and the working panel 17 are in clearance fit through the slide rails and slide ways to ensure smooth sliding.

[0046] Among them, a conforming positioning groove is provided on the adjustment platform 19 to place the wax mold to be spliced.

[0047] Deformation adjustment mechanism 3: The T-shaped slider 27 is placed in the T-shaped track 22 formed by fixing the stepped insert on the adjustment platform 19. One end of the T-shaped slider 27 is connected and fixed to the push-pull quick-change clamp on the adjustment platform 19, and the other end is connected to the contour block 25. The opening and closing reset of the contour block 25 is realized through the push-pull quick-change clamp. When it is opened, it is convenient to place the wax pattern to be assembled. After closing, the rough positioning and splicing of the wax pattern to be assembled are realized. The position of the T-shaped slider 27 is fixed by connecting with the locking buckle and the limit block 23. The fine-tuning mechanism 26 is to set a rectangular groove on the top surface of the T-shaped slider 27 and connect the fine-tuning block 28 through a cylinder and a screw. One end of the fine-tuning block 25 is connected to the contour block 25, and the other end is provided with a T-shaped limit groove. Then, the T-shaped slider and the fine-tuning block 28 are connected through the fine-tuning screw 29. By rotating the fine-tuning screw 29, the sliding of the fine-tuning block drives the contour block 25 to further realize the dimensional fine-tuning of the wax pattern to be assembled.

[0048] The fine-tuning block 28 and the T-shaped slider 27 of the deformation adjustment mechanism 3 are engraved with dimensional scale lines. During the process of adjusting the size of the wax pattern, the adjustment displacement of the fine-tuning block 28 shall not exceed the limited displacement of the dimensional scale line engraved on the T-shaped slider.

[0049] Positioning support column 7: The support column 11 is fixedly connected to the movable splicing platform 1 through screws, and the other end is provided with a theoretical position positioning hole. The adjustment platform 19 is moved in the X and Y directions by rotating the adjustment knob 20. When the theoretical position hole of the adjustment platform 19 coincides with the theoretical position positioning hole of the support column 11, the adjustment platform 19 is connected and positioned with the positioning support column 7 by using the positioning pin 12. The rough positioning of the wax group to be spliced is realized. The positioning pin 12 has a clearance fit with the theoretical position holes of the adjustment platform 19 and the positioning support column 7.

[0050] Height limiting plate 4: According to the highest plane or flat surface of the wax pattern to be assembled, the fixed bracket 30 and the adjustment platform 19 are fixedly connected through the positioning groove and screws. Then, a limit pressing plate 32 is arranged between the two fixed brackets 30 and fixed by the handle screw. The limit pressing plate 32 causes deformation when it is higher or lower than the wax pattern surface.

[0051] Re-inspection contour template 5: According to the joint position of the spliced wax pattern, the fixed bracket 30 and the contour template 31 are arranged. A rectangular groove is provided on the fixed bracket for the contour template 31. The clearance between the contour template 31 and the detection position of the spliced wax mold shall not be greater than 0.1 mm. After the detection size is qualified, the contour template 31 is locked by the handle screw to prevent secondary deformation during the welding process of the wax pattern to be assembled.

[0052] Using the above-mentioned large thin-walled wax mold splicing and calibration device, the present invention also provides a large thin-walled wax mold splicing and calibration method, including:

[0053] Step 1: Place the wax group to be spliced on the reference fixed support platform 6 and fix the wax group to be spliced through the height limiting plate 4;

[0054] Step 2: Pull open the reset structure 14 and the conformal block 15, place the wax group to be spliced in the conformal positioning groove of the adjustment platform 23, make the positioning hole of the adjustment platform coincide with the limit hole of the support column through the coordinate adjustment mechanism, and use the positioning pin to connect to position the coordinate adjustment platform 2, so as to achieve the preliminary splicing between the wax groups to be spliced. Then close the reset structure 14;

[0055] Step 3: Utilize the deformation adjustment mechanism 3, rotate the fine adjustment screw 17 to drive the fine adjustment block 16, and further drive the conformal block 26 to finely adjust the joint of the wax group to be spliced, so as to achieve the secondary adjustment between the wax groups to be spliced;

[0056] Step 4: Fix another wax group to be spliced through the height limiting plate 4, and then recheck and observe the joint position of the spliced wax group through the recheck conformal template 5. If the recheck is qualified, perform the overall dimension scanning of the wax pattern. If the recheck is unqualified, repeat Steps 2 to 4.

[0057] Step 5: If the overall dimension scanning of the wax pattern is qualified, the wax pattern splicing is completed. If the overall dimension scanning of the wax pattern is unqualified, according to the position of the out-of-tolerance dimension, repeat Steps 2 to 4 until the overall dimension of the wax pattern is qualified. Exemplarily, for the large thin-walled wax mold splicing and calibration method provided by the present invention, first place a part of the wax pattern to be assembled on the reference fixed support platform and use the positioning block to achieve positioning, then install the height limiting plate to achieve height limiting, and use this part of the wax mold as the reference. Then place another wax mold to be assembled in the conformal positioning groove of the adjustment platform, rotate the coordinate adjustment platform and the reset mechanism to achieve the preliminary splicing of the wax groups, and then finely adjust the size of the wax groups by adjusting the fine adjustment structure, and observe the fine adjustment displacement to determine whether the adjustment is effective. Then recheck the joint position through the recheck conformal template. After passing the inspection, carry out the dimension scanning and identification. If it is unqualified, repeat the above operation steps until the size of the wax group to be spliced is qualified.
