Description

Technical Field

[0001] This utility model relates to the field of rare earth electrolysis equipment technology, specifically to a clamping component for a rare earth electrolysis furnace that serves two purposes. Background Technology

[0002] Currently, rare earth electrolysis is the main method for producing rare earth metals. As the main equipment in this process, the structure of the electrolytic cell directly affects the quality of rare earth metal products, working efficiency, and production costs. Existing electrolytic furnaces typically place a molybdenum pot for collecting rare earth metals at the bottom of the furnace, while graphite anodes are installed around the furnace chamber, and a tungsten rod is inserted in the middle of the furnace chamber as the cathode. Rare earth electrolysis is carried out under the action of the inter-electrode electric field between the cathode and the anode.

[0003] Before electrolysis, a clamping assembly is needed to transfer the crucible into the electrolysis furnace, or after electrolysis, the crucible is transferred to the forming device for tilting. In the existing rare earth electrolysis furnace device, since only one electrolysis furnace is set up and the forming device is set on the furnace platform surface of the electrolysis furnace, the clamping assembly can complete the above-mentioned crucible transfer action by only making a linear translational movement. However, when faced with a large production volume demand, this type of rare earth electrolysis furnace device will not be able to meet the production volume demand. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a clamping component for rare earth electrolysis furnace that can be used in two ways.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a dual-purpose clamping assembly for a rare earth electrolysis furnace, comprising:

[0006] A first electrolytic furnace and a second electrolytic furnace are arranged adjacent to each other, with a transfer area defined between them. Within the transfer area, a crucible extraction device and a discharge forming device are arranged opposite each other.

[0007] The crucible extraction device includes a base assembly, a Z-axis rotation module disposed on the base assembly, a Z-axis lifting module disposed on the moving end of the Z-axis rotation module, and a linear transfer module disposed on the moving end of the Z-axis lifting module. The moving end of the linear transfer module is provided with a clamping assembly.

[0008] Both the first and second electrolytic furnaces are provided with an electrolytic chamber for accommodating crucibles. The material discharge forming device is provided with a crucible discharge assembly and a forming receiving assembly for positioning crucibles. The electrolytic chamber and the crucible discharge assembly are both located within the transfer path of the clamping assembly. The crucible discharge assembly receives crucibles from the first and second electrolytic furnaces and transfers them to the forming receiving assembly.

[0009] Furthermore, the linear moving module is configured to extend from the center of the Z-axis rotating module toward the transfer area, and the linear moving module moves above the first and second electrolytic furnaces via the Z-axis rotating module.

[0010] Furthermore, the first electrolytic furnace, the second electrolytic furnace, the crucible extraction device, and the discharge forming device are all set on a concrete base layer on the same horizontal reference plane.

[0011] The base assembly includes a support base connected to the Z-axis rotation module, a first base plate embedded in the base layer, and a positioning plate fixed to the bottom of the support base. The base layer also has a plurality of first embedded parts, which are fixedly connected to the positioning plate.

[0012] Furthermore, the material discharge molding device also includes a machine base, and the crucible discharge component and the molding receiving component are both set on the machine base. The bottom of the machine base is provided with a second base plate pre-embedded in the base layer. The second base plate is flush with the surface of the base layer, and the bottom of the second base plate is provided with a plurality of base pillars inserted into the base layer.

[0013] Furthermore, the first substrate has an extension plate disposed at the bottom of the first electrolytic furnace and the second electrolytic furnace, and both the first electrolytic furnace and the second electrolytic furnace include a support platform, at least one end of the support platform being disposed on the extension plate.

[0014] Furthermore, the base layer is also provided with a plurality of second embedded parts, the second embedded parts including a main rod body embedded in the base layer and an upper rod body extending from the upper end of the main rod body. The upper rod body has a horizontal bend, and the upper surface of the upper rod body is flush with the lower surface of the first base plate and / or the extension plate. The upper surfaces of the plurality of upper rod bodies define an adjustment plane.

[0015] Furthermore, the clamping assembly includes multiple clamping units; the end of the support platform is provided with a correction plate, which is located within the movement path of the clamping unit, and the correction plate is provided with correction points corresponding to the clamping unit, the correction points being arranged with respect to the gripping or opening posture of the clamping unit.

[0016] Furthermore, a conductive furnace platform is provided above the support platform, an upper support column is provided between the conductive furnace platform and the support platform, and a lower support column is provided inside the support platform. The upper support column and the lower support column are fixedly connected by bolts and abut against the end of the correction plate.

[0017] Furthermore, the clamping unit includes a transmission arm that is driven to the power end of the clamping assembly, and a clamping arm for performing gripping and releasing actions. The clamping arm is inserted into the bottom of the transmission arm, and there is a relatively cooperating inclined surface between the clamping arm and the transmission arm. The clamping arm and the transmission arm are fixedly connected by bolts, and the bolts are inserted through the inclined surface.

[0018] Furthermore, the material discharge forming device also includes a machine base, and the crucible discharge assembly and the forming receiving assembly are mounted on the machine base;

[0019] The crucible discharge assembly includes a positioning clamping module acting on the lower part of the crucible, and a tilting discharge module that drives the positioning clamping module to rotate. The tilting discharge module includes a rotating disk mounted on the machine base, and a rotary drive unit that drives the rotating disk to rotate. The positioning clamping module is mounted on the rotating disk.

[0020] The forming and receiving assembly includes a forming box for receiving molten metal and a moving module for driving the forming box to move. The forming box is disposed on the tilting side of the tilting and discharging module. The moving module includes a swing plate mounted on the machine base and a linear push unit for driving the swing plate to rotate.

[0021] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0022] This invention arranges a transfer area between a first and a second electrolytic furnace, and sets up a crucible extraction device and a discharge forming device within the transfer area. The clamping assembly is initially located within the transfer area and can form a working path through the crucibles of the first and second electrolytic furnaces and the crucible clamping position of the discharge forming device through the coordinated action of the Z-axis rotation module, the Z-axis lifting module and the linear transfer module. Thus, the crucible transfer work on two or more electrolytic furnaces can be realized by a single crucible extraction device, realizing the multi-purpose nature of the clamping assembly. Furthermore, this layout of electrolytic furnaces, crucible extraction devices and discharge forming devices greatly reduces the space occupied by multiple electrolytic furnaces, meets the needs of production efficiency, and solves the cost and space problems caused by the requirement of equipping each electrolytic furnace with a crucible extraction device in the prior art.

[0023] On the other hand, the clamping assembly is fixed by the first base plate and the positioning plate in the base assembly. The first base plate is embedded in the base layer, and the positioning plate is fixed on the first base plate by the first embedded part. The support base is fixed on the positioning plate, and the first electrolytic furnace and the second electrolytic furnace are both set on the horizontal reference plane defined by the first base plate, thereby improving the horizontality between the clamping unit of the clamping assembly and the electrolytic furnace. This helps to ensure the clamping stability of the clamping unit on the crucible in the electrolytic furnace and reduce the offset between the clamping surface of the clamping unit and the crucible.

[0051] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0052] It should be understood that although the terms upper, middle, lower, top, one end, etc., appear in this document to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish the elements from each other for ease of understanding, and are not used to define any directional or sequential restrictions.

[0053] like Figure 1-18 As shown, a dual-purpose clamping assembly 7 for a rare earth electrolysis furnace includes: a first electrolysis furnace 1 and a second electrolysis furnace 2 arranged adjacent to each other and spaced apart. A transfer area 3 is defined between the first electrolysis furnace 1 and the second electrolysis furnace 2. A crucible extraction device 4 and a discharge forming device 5 are arranged opposite to each other in the transfer area 3. The crucible extraction device 4 is used to switch the crucible between the electrolysis furnace and the discharge forming device 5, and the discharge forming device 5 is used to collect the molten metal in the crucible.

[0054] The crucible extraction device 4 includes a base assembly 6 fixed on a concrete base layer 8, a Z-axis rotation module 4.1 mounted on the base assembly 6, a Z-axis lifting module 4.2 mounted on the moving end of the Z-axis rotation module 4.1, and a linear transfer module 4.3 mounted on the moving end of the Z-axis lifting module 4.2. The moving end of the linear transfer module is provided with a clamping assembly 7. The clamping assembly 7 is preferably a clamping unit 7.1 driven by an electric three-jaw chuck to perform gripping and releasing actions. The clamping unit 7.1 is rod-shaped and has a claw portion for gripping the crucible at the bottom.

[0055] Both the first electrolytic furnace 1 and the second electrolytic furnace 2 are provided with an electrolytic chamber for accommodating crucibles. The material discharge forming device 5 is provided with a crucible discharge assembly 12 and a forming receiving assembly 13 for positioning crucibles. The electrolytic chamber and the crucible discharge assembly 12 are both located within the transfer path of the clamping assembly 7. The crucible discharge assembly 12 receives crucibles from the first electrolytic furnace 1 and the second electrolytic furnace 2 and transfers them to the forming receiving assembly 13.

[0056] In its initial state, the clamping assembly 7 is located within the transfer area 3. Through the coordinated action of the Z-axis rotation module 4.1, the Z-axis lifting module 4.2, and the linear transfer module 4.3, it forms a working path through the crucibles of the first electrolytic furnace 1 and the second electrolytic furnace 2, as well as the crucible clamping position of the discharge forming device 5. Thus, the crucible transfer work on two or more electrolytic furnaces can be realized through a single crucible extraction device 4, achieving the multi-purpose functionality of the clamping assembly 7. Furthermore, this layout of the electrolytic furnaces, crucible extraction device 4, and discharge forming device 5 greatly reduces the space occupied by multiple electrolytic furnaces, meets the requirements of production efficiency, and solves the cost and space problems caused by the requirement of configuring a crucible extraction device 4 for each electrolytic furnace in the prior art.

[0057] The transfer space also includes the outer contour of the first electrolytic furnace 1 and the second electrolytic furnace 2.

[0058] from Figure 1 and Figure 2 As can be seen from this embodiment, the linear moving module is set to extend from the center of the Z-axis rotating module 4.1 toward the transfer area 3, and the linear moving module moves above the first electrolytic furnace 1 and the second electrolytic furnace 2 through the Z-axis rotating module 4.1. That is, the linear moving module extends in the horizontal direction. By setting the Z-axis rotating module 4.1, the linear moving module does not need to be set with a fixed linear moving frame between the first electrolytic furnace 1 and the second electrolytic furnace 2, reducing the space occupation. In the non-transfer state, the clamping component 7 and the linear moving module are rotated into the transfer space, thereby avoiding interference with the cathode tungsten rod on the electrolytic furnace.

[0059] It should be pointed out that, as Figure 4 As shown, in order to ensure the clamping stability of the clamping unit 7.1 on the first electrolytic furnace 1 and the second electrolytic furnace 2, and to reduce the deviation between the three on the horizontal plane, a concrete base layer 8 is set up. The first electrolytic furnace 1, the second electrolytic furnace 2, the crucible extraction device 4 and the discharge forming device 5 are all set on the same horizontal reference plane on the concrete base layer 8.

[0060] Further reference Figures 3 to 6The base assembly 6 includes a support base 6.1 connected to the Z-axis rotation module 4.1, a first base plate 6.2 embedded in the base layer 8, and a positioning plate 6.3 fixed to the bottom of the support base 6.1. The upper surface of the first base plate 6.2 is flush with the concrete base layer 8, and the base layer 8 is also provided with a plurality of first embedded parts 6.4. The first embedded parts 6.4 pass through the base plate and are fixedly connected to the positioning plate 6.3, thereby providing a fixed reference connection surface for the positioning plate 6.3. .4 has a threaded portion 6.41 extending from the base plate and the positioning plate 6.3. The end of the threaded portion 6.41 is provided with a nut 6.5, thereby fixing the positioning plate 6.3 on the base plate. The bottom of the support base 6.1 is provided with a clearance hole 6.12 that matches the nut 6.5. The flatness between the positioning plate 6.3 and the base plate is adjusted by the nut 6.5. When disassembling and debugging the crucible extraction device 4, it is only necessary to remove the support base 6.1 from the positioning plate 6.3, which effectively improves the accuracy and convenience of secondary assembly.

[0061] Combination Figure 5 and Figure 6 As shown, to further ensure the ease of disassembly and assembly of the base assembly 6 and the reliability of positioning after secondary assembly, the positioning plate 6.3 is provided with at least one positioning post 6.31, and the bottom of the support base 6.1 is provided with a positioning hole 6.11 that matches the positioning post 6.31. The positioning post 6.31 and the positioning hole 6.11 are set about the rotation center of the clamping assembly 7. The center position of the base assembly 6 is corrected by the cooperation of the positioning post 6.31 and the positioning hole 6.11.

[0062] like Figure 9 As shown, as a further embodiment of fixing the support base 6.1, positioning plate 6.3, and base plate, the position of the first embedded part 6.4 is arranged radially outward about the positioning post 6.31 and positioning hole 6.11, and forms a first fixing area 6.7 and a second fixing area 6.8 on the positioning plate 6.3. The first fixing area 6.7 is specifically located on the periphery of the positioning post 6.31, and the second fixing area 6.8 is specifically located on the contour side of the positioning plate 6.3. The support base 6.1 and the positioning plate 6.3 are fixedly connected by threaded connectors, and a first adjustment position for setting the threaded connectors is arranged on the bottom periphery of the support base 6.1. The first adjustment position is also correspondingly arranged on the positioning plate 6.3 and the base plate. The first adjustment position defines a third fixing area 6.9, which is located between the first fixing area 6.7 and the second fixing area 6.8. By adjusting the tightness of the multiple threaded connectors in the fixing area, the levelness between the support base 6.1, positioning plate 6.3, and base plate is adjusted.

[0063] Further reference Figure 4As a further arrangement of the horizontal reference, the first substrate 6.2 has an extension plate 6.21 disposed at the bottom of the first electrolytic furnace 1 and the second electrolytic furnace 2. The extension plate 6.21 is specifically disposed on both sides of the first substrate 6.2 and integrally formed with the first substrate 6.2. The first electrolytic furnace 1 and the second electrolytic furnace 2 both include a support platform 9 and a furnace platform assembly mounted on the support platform 9. A furnace body 9.5 is disposed at the center of the support platform 9 and the furnace platform assembly. Electrode plates are disposed on the support platform 9, and anode graphite is disposed on the furnace platform assembly. An electrolysis chamber is formed inside the furnace body 9.5. At least one end of the support platform 9 is disposed on the extension plate 6.21. Through the above improvements, the first substrate 6.2 also provides a horizontal reference surface for the first electrolytic furnace 1 and the second electrolytic furnace 2, thereby ensuring the levelness between the first electrolytic furnace 1, the second electrolytic furnace 2 and the crucible extraction device 4, and reducing the deviation between the clamping unit 7.1 and the crucible.

[0064] Specifically, the base layer 8 is further provided with a plurality of second embedded parts 10. The second embedded parts 10 include a main rod 10.1 embedded in the base layer 8, an upper rod 10.2 extending to the upper end of the main rod 10.1, and a lower rod 10.3 extending to the lower end of the main rod 10.1. The main rod 10.1 extends vertically, and the upper rod 10.2 and the lower rod 10.3 have horizontal bends. Preferably, the second embedded parts 10 are set as tubular members, and the upper surfaces of the plurality of upper rods 10.2 jointly define the adjustment plane, specifically the horizontal cross-section of the tubular member, and the adjustment plane of the upper rods 10.2 is flush with the lower surface of the first base plate 6.2 and / or the extension plate 6.21.

[0065] In this embodiment, the second embedded part 10 forms a horizontal adjustment plane, which serves as the horizontal base surface of the substrate and constitutes the first horizontal construction surface 14 of the base layer 8. At this time, the first embedded part 6.4 is placed in the base layer 8, and the fixing holes on the substrate are aligned with the first embedded part 6.4 to position the substrate on the first horizontal construction surface 14. Then, the base layer 8 is further processed so that the upper surface of the substrate serves as the second horizontal construction surface 15, providing a horizontal reference surface for the first electrolytic furnace 1, the second electrolytic furnace 2, and the crucible extraction device 4. Through the above improvements, the lower surface of the substrate is guaranteed to be horizontal through the second embedded part 10, and the upper surface of the substrate is guaranteed to be horizontal through the construction of the concrete base layer 8, further improving the levelness of the first electrolytic furnace 1, the second electrolytic furnace 2, and the crucible extraction device 4, and effectively reducing height deviation.

[0066] Preferably, there are multiple second embedded parts 10, which are arranged on both sides of the installation area formed by the first embedded part 6.4. Specifically, the second embedded parts 10 are arranged below the extension plate 6.21, thereby further improving the leveling of the substrate. The support platform 9 of the first electrolytic furnace 1 and the second electrolytic furnace 2 has a support end plate 9.4 mounted on the extension plate 6.21, thereby ensuring the reliability of the crucible extraction device 4 when transferring crucibles for the first electrolytic furnace 1 and the second electrolytic furnace 2.

[0067] like Figure 8 As shown, in some other embodiments, the discharge molding device 5 further includes a machine base 5.1, and the crucible discharge assembly 12 and the molding receiving assembly 13 are both disposed on the machine base 5.1. The bottom of the machine base 5.1 is provided with a second substrate 5.2 pre-embedded in the base layer 8. The second substrate 5.2 is flush with the upper surface of the base layer 8, and the bottom of the second substrate 5.2 is provided with a plurality of base pillars 5.21 inserted in the base layer 8. In this way, the second substrate 5.2 is pre-embedded with a reference surface flush with the upper surface of the substrate, and the reliability of the second substrate 5.2 is further improved by the base pillars 5.21.

[0068] like Figure 10 As shown, specifically, the clamping assembly 7 includes multiple clamping units 7.1; the end of the support platform 9 is provided with a correction plate 11, which is located within the movement path of the clamping unit 7.1, and the correction plate 11 is provided with correction points 11.1 corresponding to the clamping unit 7.1. The correction points 11.1 are arranged with respect to the gripping or opening posture of the clamping unit 7.1. Thanks to the first substrate 6.2 and the base layer 8 as the horizontal base surface, the horizontal posture reliability of the correction plate 11 is ensured, thereby improving the reliability of the correction reference of the correction plate 11.

[0069] As one embodiment of the calibration point 11.1, the calibration point 11.1 can be a calibration pattern reference flush with the end face of the calibration plate 11, or it can be composed of multiple calibration posts disposed on the calibration plate 11. The calibration posts pass through the calibration plate 11 to form the calibration point 11.1. The calibration posts extend out of or are flush with the end face of the calibration plate 11. Alternatively, the calibration plate 11 can be adjusted by adjusting the relative height of the calibration posts. For example, the calibration posts can be fixed to the calibration plate 11 by threads.

[0070] As a further arrangement of the calibration points 11.1 and the clamping units 7.1, there are multiple clamping units 7.1 arranged in a circumferential direction, and multiple calibration points 11.1 are arranged circumferentially, and the calibration points 11.1 define a calibration contour, which is consistent with the expected contour of the clamping units 7.1. The calibration center of the calibration center corresponds to the clamping center of the clamping unit 7.1. That is, after the calibration of the clamping unit 7.1 and the calibration points 11.1 is completed, the center alignment of the clamping unit 7.1 is also completed at the same time.

[0071] As an example, multiple clamping units 7.1 are arranged about the clamping center, and multiple correction points 11.1 located on the same circumference are provided on the correction plate 11. The purpose is to match the clamping units 7.1 under different rotation angles to improve the convenience of correction reference work. In this embodiment, the number of correction points 11.1 is 6, and they are arranged at equal angular intervals about the circumference. The number of clamping units 7.1 is 3.

[0072] like Figure 11 and Figure 12 As shown, in one embodiment of adjusting the clamping unit 7.1, the clamping unit 7.1 includes a transmission arm 7.11 that is tractively connected to the power end of the clamping assembly 7, and a clamping arm 7.12 for performing gripping and releasing actions. Specifically, the transmission arm 7.11 is hinged to a three-jaw chuck and the three-jaw chuck further drives the clamping arm 7.12. The clamping arm 7.12 is inserted into the bottom of the transmission arm 7.11, and there is a relatively mating inclined surface 7.13 between the clamping arm 7.12 and the transmission arm 7.11. The clamping arm 7.12 and the transmission arm 7.11 are fixedly connected by bolts, which pass through the inclined surface 7.13. Thus, after determining that the clamping unit 7.1 has an offset through the correction point 11.1, the relative position of the clamping arm 7.12 and the transmission arm 7.11 can be further adjusted by adjusting the tightness of the bolts between the clamping arm 7.12 and the transmission arm 7.11.

[0073] Preferably, the lower end of the transmission arm 7.11 is provided with a trapezoidal linkage block 7.2, and the upper end of the clamping arm 7.12 is provided with a linkage groove 7.3 that matches the linkage block 7.2. The inclined surface 7.13 is specifically formed on both sides of the linkage block 7.2. At least two second adjusting bolt positions are provided at the upper end of the clamping arm 7.12. The second adjusting bolt positions are arranged at intervals along the length of the clamping arm 7.12 and pass through the linkage groove 7.3 and the linkage block 7.2.

[0074] Furthermore, a T-shaped block is provided at the lower end of the linkage block 7.2, and a T-shaped groove matching the T-shaped block is provided at the bottom end of the linkage groove 7.3. Through the setting of the T-shaped block and the T-shaped groove, the pre-positioning of the transmission arm 7.11 and the clamping arm 7.12 is realized.

[0075] like Figures 13 to 15As shown, specifically, the furnace platform assembly also includes a conductive furnace platform 9.1 arranged above the support platform 9. An upper support column 9.2 is provided between the conductive furnace platform 9.1 and the support platform 9. A lower support column 9.3 is provided inside the support platform 9. The upper support column 9.2 and the lower support column 9.3 are fixedly connected by bolts and abut against the end of the correction plate 11. Preferably, the lower support column 9.3 is provided on the support end plate 9.4, so that the levelness of the correction plate 11 is ensured by the extension plate 6.21 and the base plate. The levelness of the correction plate 11 on the furnace platform assembly is adjusted by adjusting the bolt fit between the upper support column 9.2 and the lower support column 9.3.

[0076] The correction plate 11 has a connecting part 11.2 at its end. A first flange 9.21 surface is fixedly provided on the periphery of the upper support column 9.2, abutting against the upper end face of the connecting part 11.2. A second flange 9.31 surface is provided on the periphery of the lower support column 9.3, abutting against the lower end face of the connecting part 11.2. A plurality of first adjusting bolt positions are provided between the first flange 9.21 surface and the second flange 9.31 surface. The first adjusting bolt positions are spaced apart in the circumferential direction about the center of the support column. In this embodiment, the correction point 11.1 is set about the center of the correction plate 11. By setting the connecting part 11.2 at the end of the correction plate 11, the bolts on the first flange 9.21 surface and the second flange 9.31 surface can be adjusted, thereby adjusting the levelness of the correction plate 11 to ensure the reliability of the correction work of the clamping unit 7.1. In addition, the correction plate 11 is also held in position by the upper support column 9.2 and the lower support column 9.3, improving the stability of the correction plate 11 after the position adjustment.

[0077] like Figure 16 and Figure 17 As shown, as one embodiment of the discharge forming device 5, the discharge forming device 5 also includes a machine base 5.1, and the crucible discharge assembly 12 and the forming receiving assembly 13 are disposed on the machine base 5.1;

[0078] The crucible discharge assembly 12 includes a positioning clamping module 12.1 acting on the lower part of the crucible, and a tilting discharge module 12.2 that drives the positioning clamping module 12.1 to rotate. The tilting discharge module 12.2 includes a rotating disk 12.3 mounted on the machine base 5.1, and a rotary drive unit 12.4 that drives the rotating disk 12.3 to rotate. The positioning clamping module 12.1 is mounted on the rotating disk 12.3.

[0079] The forming receiving assembly 13 includes a forming box 13.1 for receiving molten metal and a moving module 13.2 for driving the forming box 13.1 to move. The forming box 13.1 is disposed on the tilting side of the tilting discharge module 12.2. The moving module 13.2 includes a swing plate 13.3 mounted on the machine base 5.1 and a linear push unit 13.4 for driving the swing plate 13.3 to rotate.

[0080] Throughout the entire material discharge and forming process, the crucible is removed from the electrolytic furnace using a gripper structure, and the crucible containing electrolyte is placed on the positioning and clamping module 12.1. The positioning and clamping module 12.1 clamps and fixes the crucible. The rotation drive unit 12.4 drives the rotating disk 12.3 to rotate, causing the molten metal in the crucible to be poured into the forming box 13.1 for forming. When the clamping assembly 7 is transferring the crucible, the linear push unit 13.4 drives the swing plate 13.3 away from the positioning and clamping module 12.1 to avoid the gripper structure. When pouring the molten metal, the linear push unit 13.4 drives the swing plate 13.3 closer to the positioning and clamping module 12.1 to receive the material.

[0081] Further explanation of the positioning and clamping module 12.1: The positioning and clamping module 12.1 includes a rotating arm 12.5 connected to the rotating disk 12.3, a clamping cylinder 12.6 disposed on the rotating arm 12.5, a first clamping piece 12.7 connected to the output end of the clamping cylinder 12.6, a connecting plate 12.8 connected to the rotating arm 12.5, and a second clamping piece 12.9 disposed on the connecting plate 12.8, wherein the first clamping piece 12.7 and the second clamping piece 12.9 form a space for the crucible to be placed. The clamping space is provided. Specifically, the rotating arm 12.5 is fixed on the rotating disk 12.3 and extends to the outside of the rotating disk 12.3. The clamping cylinder 12.6 is offset at the center of the rotating disk 12.3. The clamping assembly 7 is used to clamp the crucible into the clamping space. When the clamping cylinder 12.6 drives the second clamping piece 12.9 to approach the first clamping piece 12.7, the crucible is clamped. The rotating arm 12.5 is rotated by the rotating disk 12.3 to complete the pouring of the molten metal into the forming box 13.1.

[0082] Specifically, regarding the further explanation of the forming and receiving assembly 13, a fixed plate 13.5 is provided on the machine base 5.1, and a rotating seat 13.6 is inserted into the fixed plate 13.5. The swing plate 13.3 is rotated on the rotating seat 13.6. The moving end of the swing plate 13.3 is connected to a limiting plate 13.7. The forming box 13.1 is placed on the limiting plate 13.7. The driving end of the swing plate 13.3 is rotatably connected to the moving end of the linear push unit 13.4. The fixed end of the linear push unit is rotatably connected to the machine base. The linear push unit 13.4 drives the swing plate 13.3 to rotate on the fixed plate 13.5, causing the forming box 13.1 to move, so as to receive material or avoid the clamping assembly 7 that grabs the crucible. In addition, the swing plate 13.3 drives the forming box 13.1 to swing, which helps to improve the uniformity of the molten metal in the forming box 13.1, avoids accumulation after solidification, and facilitates the subsequent treatment of oxides on the surface of the molten metal.

They can both be configured as execution blocks driven by the lead screw nut 6.5 structure.

[0084] As a further embodiment of the Z-axis rotation module 4.1, the base assembly 6 also includes a support frame 6.6 fixed to the support base plate. The Z-axis rotation module 4.1 includes a rotation module placed inside the support frame 6.6. The Z-axis rotation module 4.1 serves as a support for the Z-axis lifting module 4.2 and the linear movement module, and is fixedly installed by the support base plate. The support base plate ensures horizontality through the positioning plate 6.3 and the base plate. In addition, placing the rotation module inside the support frame 6.6 makes full use of the vertical space.

[0085] Specifically, the rotation module includes a vertically arranged rotation unit 4.11 and a first transmission base 4.12 disposed on the output end of the rotation unit 4.11. The first transmission base 4.12 is provided with a planetary gear set 4.13, and the output end of the planetary gear set 4.13 is provided with a second transmission base 4.14. The Z-axis lifting module 4.2 is disposed on the second transmission base 4.14. The first transmission base is provided with a first bevel gear 4.15 connected to the input end of the planetary gear set 4.13. The first bevel gear is connected to the output shaft of the rotation unit. The first bevel gear 4.15 meshes with a second bevel gear 4.16. A side transmission shaft 4.17 extends from the second bevel gear 4.16. The side transmission shaft 4.17 is vertically arranged about the output axis of the rotation unit 4.11. It can be connected to a hand tool to adjust the circumferential position of the clamping assembly 7 in emergency situations or in the event of a power failure. In some embodiments, the side transmission shaft 4.17 can also be connected to a reducer to further improve the stability of the clamping assembly 7 during rotation.
