Description

Technical Field

[0001] This invention relates to the field of crucible manufacturing technology, and more specifically to a machine tool for integrated processing of crucible semi-finished products, including lid cutting, grinding and polishing. Background Technology

[0002] Calcinated coke is produced by placing raw coke in a calcining facility and heating it at a high temperature of 1250℃-1350℃. This process removes volatiles and moisture from the raw material, causing it to shrink and stabilize in volume, thus transforming the raw coke into calcined coke. Calcinated coke is typically a mixture of varying sizes, with the diameter of the blocks generally less than 80mm. Its primary use is as a raw material aggregate in the production of carbon products. Calcinated coke can also be used to make crucibles for the production of graphene.

[0003] On the same day, the applicant filed a utility model patent application entitled "A Hot Press Molding Mold for Graphite Crucibles," which discloses a mold for manufacturing crucibles, comprising a mold shell, a mold core, and a switch door, as well as oil supply and return pipelines installed on the outer wall of the mold shell; the raw material is extruded from the feed port into the forming channel between the mold shell and the mold core through an extruder, so that the crucible body and the crucible bottom are formed integrally in one step. The structure of the crucible manufactured is as follows: Figure 1 and Figure 2 As shown.

[0004] However, products manufactured from the above molds, such as Figure 1 and Figure 2 The crucible shown is only a semi-finished product. First, the inner surface, bottom surface, and opening edge of the crucible semi-finished product after being extruded by the mold are relatively rough and require further polishing. In addition, the crucible semi-finished product lacks a lid, which needs to be made separately. However, making a lid requires the development of a new mold, and the lid made still needs to be polished. This not only increases the production input cost but also consumes a lot of manpower and time.

[0005] Further research revealed that by adjusting the mold dimensions in the aforementioned patent applications to increase the thickness of the crucible bottom, a layer of the bottom could be directly cut off after the crucible semi-finished product is extruded and processed into a lid. Figure 3 As shown. This eliminates the need for mold development in the production of the lid, and the cut lid dimensions are more suitable, resulting in a better fit, such as... Figure 4 The diagram shows the fitting of the top edge opening of the lid and the crucible semi-finished product.

[0006] Therefore, in order to meet the requirements of further processing of the above-mentioned crucible semi-finished products, as well as rough surface grinding and lid cutting, and to make the operation simpler and more efficient, it is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0007] In view of this, the present invention provides a machine tool for integrated processing of crucible semi-finished products, including cutting, lid cutting, and grinding, in order to solve the above-mentioned technical problems.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A machine tool for integrated processing of crucible semi-finished products, including:

[0010] Rotating part; the rotating part includes a rotating cylinder, the semi-finished crucible to be processed is clamped and fixed inside the rotating cylinder, and the two ends of the semi-finished crucible protrude from the two end openings of the rotating cylinder; the rotating cylinder rotates when the semi-finished crucible is being cut for the lid and ground for the inner wall.

[0011] The cutting section includes a double saw blade mechanism located outside the bottom of the crucible semi-finished product and capable of radially cutting in from the outside of the bottom of the crucible to cut the cover from the bottom of the crucible.

[0012] The grinding section includes a first cutting tool mechanism located on one side of the open end of the crucible semi-finished product. The first cutting tool mechanism can enter axially from the open end of the crucible semi-finished product and grind the crucible body and the inner wall of the crucible bottom of the crucible semi-finished product.

[0013] Through the above technical solution, the processing machine tool provided by the present invention can simultaneously perform lid cutting and grinding on crucible semi-finished products. After the crucible semi-finished product is loaded into the rotating drum and clamped, it begins to rotate and process. The double saw blade mechanism cuts radially from the outside of the bottom of the crucible. The saw blade closer to the rotating drum is used for layer cutting, and the saw blade farther from the rotating drum is used for grinding the bottom surface. The two saw blades operate simultaneously, completing the processing steps of lid cutting, grinding, and crucible bottom grinding together. After the lid cutting is completed, the first cutting tool mechanism enters axially from the open end of the crucible semi-finished product to grind the crucible body and the inner wall of the bottom of the crucible semi-finished product, completing the grinding operation. The overall machine tool structure is simple, and it can further process the crucible semi-finished product, making it not only smooth after one machine tool processing, but also saving the step of processing the lid separately, which greatly improves the crucible processing efficiency.

[0014] Preferably, in the above-mentioned integrated machining tool for cutting and grinding crucible semi-finished products, the cutting part further includes a second turning tool mechanism. The second turning tool mechanism is located on the outer side of the crucible bottom of the semi-finished product and opposite to the double saw blade mechanism. The second turning tool mechanism can radially cut into the crucible bottom from the outer side, and while the double saw blade mechanism is cutting, it turns the protruding edge of the lid on the outer bottom surface of the crucible bottom. The lid generally has a protruding edge on its inner bottom when it is fastened, which can achieve radial limiting after fastening. Therefore, in order to save machining steps, the present invention provides a second turning tool mechanism on the other side of the double saw blade mechanism, which can simultaneously machine the protruding edge while the double saw blade mechanism is cutting the lid, thus improving work efficiency.

[0015] Preferably, in the above-mentioned integrated machining tool for cutting, grinding, and finishing crucible semi-finished products, the double saw blade mechanism and the second cutting tool mechanism are respectively mounted on two moving platforms. These moving platforms are capable of axial and radial displacement relative to the crucible semi-finished product. The moving platforms are slide-rail type X-axis and Y-axis moving platforms, capable of controlling the movement of the double saw blade mechanism and the second cutting tool mechanism in a plane, and can adaptively control the grinding process according to the crucible position and processing dimensions.

[0016] Preferably, in the above-mentioned integrated machining tool for cutting, polishing, and finishing crucible semi-finished products, the double saw blade mechanism, the first cutting tool mechanism, and the second cutting tool mechanism are all rotating mechanical structures driven by an electric motor and transmitted through belts and pulleys. This traditional motor-driven, belt-driven structure is simple in overall design and provides stable and reliable drive transmission.

[0017] Preferably, in the above-mentioned integrated machining tool for cutting and grinding crucible semi-finished products, the grinding unit further includes a slide rail drive platform. The first cutting tool mechanism is mounted on the slide rail drive platform, which can achieve axial and radial displacement drive relative to the crucible semi-finished product. The slide rail drive platform also adopts a slide rail type X-axis and Y-axis moving platform, which can control the movement of the first cutting tool mechanism in the plane, facilitate the control of the cutting tool body of the first cutting tool mechanism entering the crucible body of the crucible semi-finished product, and effectively control the grinding dimensions.

[0018] Preferably, the above-mentioned integrated machining tool for cutting, polishing, and finishing crucible semi-finished products further includes a feeding unit. The feeding unit includes an arc-shaped base frame located at one end of the crucible bottom of the semi-finished product. Rollers are rotatably mounted on the arc-shaped base frame. The semi-finished crucible is placed on the arc-shaped base frame and can be pushed into the inner side of the rotating drum under external force. The feeding unit facilitates the feeding of the semi-finished crucible into the rotating drum. The semi-finished crucible is placed flat on the arc-shaped base frame and can be directly pushed into the rotating drum by the rolling of the rollers, making it more convenient to use.

[0019] Preferably, in the above-mentioned integrated machining tool for cutting, polishing, and finishing crucible semi-finished products, a positioning mechanism is connected to the arc-shaped base frame. This positioning mechanism is a foldable and retractable linkage structure. When the positioning mechanism is raised and locked, it can position the bottom of the crucible. When the positioning mechanism is unlocked and folded, it can be placed within the groove of the arc-shaped base frame. To ensure that the crucible semi-finished product can be accurately clamped inside the rotating drum, the positioning mechanism limits its position, which helps improve the machining accuracy of the double saw blade mechanism and the second cutting tool mechanism.

[0020] Preferably, in the above-mentioned integrated machining tool for cutting, polishing, and finishing crucible semi-finished products, the rotating part further includes a clamping mechanism and a braking mechanism; the clamping mechanism includes jaws and a locking clamp; there are multiple jaws, and the multiple jaws are rotatably connected to the side wall of the rotating drum via pins, and the locking clamp is threaded to the outside of the rotating drum; the braking mechanism is a multi-link structure, and can drive a brake pad to wrap tightly around the outside of the locking clamp through the multi-link structure. When the brake pad wraps tightly around the locking clamp, and the rotating drum rotates, the locking clamp generates radial displacement, pushing the jaws to clamp the outer wall of the crucible body. Through the cooperation of the clamping mechanism and the braking mechanism, the crucible semi-finished product can be clamped by the jaws by controlling the rotation of the rotating drum, and when the braking mechanism is released, it will not affect the independent rotation of the rotating drum.

[0021] Preferably, the above-mentioned integrated machining tool for cutting, grinding, and polishing crucible semi-finished products further includes a clamping mechanism. The clamping mechanism is mounted above the rotary drum and can be controlled by a hydraulic cylinder to move towards the open end of the crucible semi-finished product, and is clamped to the open end of the crucible semi-finished product by a clamping plate connected to the support. The clamping mechanism is designed to prevent the crucible semi-finished product from shifting during lid cutting. Therefore, the clamping mechanism is lowered during lid cutting and raised during inner wall grinding to prevent interference with the first cutting tool mechanism.

[0022] Preferably, in the above-mentioned integrated machining tool for cutting and grinding crucible semi-finished products, the grinding unit further includes a saw blade mechanism. The saw blade mechanism is located outside the open end of the crucible semi-finished product and can radially cut in from the outside of the open end of the crucible body to grind the edge of the opening. To facilitate the grinding of the opening edge, an independent saw blade mechanism is provided to grind the opening edge of the crucible semi-finished product separately, avoiding the problem of excessively high control precision and difficulty in operation when using the first cutting tool mechanism for grinding.

[0058] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0059] See appendix Figure 1 To be continued Figure 5 This invention discloses an integrated machining tool for cutting, polishing, and grinding crucible semi-finished products, comprising:

[0060] Rotating part 1; Rotating part 1 includes a rotating cylinder 11, the crucible semi-finished product 5 to be processed is clamped and fixed inside the rotating cylinder 11, and the two ends of the crucible semi-finished product 5 protrude from the two end openings of the rotating cylinder 11; the rotating cylinder 11 rotates when the crucible semi-finished product 5 is being cut on the lid 51 and ground on the inner wall.

[0061] Cutting part 2; The cutting part 2 includes a double saw blade mechanism 21, which is located outside the bottom 53 of the crucible semi-finished product 5 and can be radially cut from the outside of the bottom 53 to cut the cover 51 from the bottom 53.

[0062] Grinding section 3; Grinding section 3 includes a first cutting tool mechanism 31, which is located on one side of the open end of the crucible semi-finished product 5. The first cutting tool mechanism 31 can enter axially from the open end of the crucible semi-finished product 5 and grind the inner wall of the crucible body 52 and the bottom 53 of the crucible semi-finished product 5.

[0063] Example 1:

[0064] See appendix Figure 12 To be continued Figure 18 The rotating part 1 includes a rotating cylinder 11, which is supported by four support frames 14 symmetrically arranged on both sides. Each support frame 14 includes a triangular support base 141 and support wheels 142 rotatably connected to the triangular support base 141. Thus, the rotating cylinder 11 can rotate under the rolling support of the four support wheels 142. To further improve the stability of the rotating cylinder 11's rotation and prevent axial movement, at least one set of support wheels 142 has a limiting groove 1421, and the outer wall of the rotating cylinder 11 has a radially protruding limiting ring 111 that mates with the limiting groove 1421. Thus, the axial position of the rotating cylinder 11 is limited by the cooperation of the limiting groove 1421 and the limiting ring 111, preventing axial movement.

[0065] The rotating drum 11 has a corresponding driving force: a first transmission belt 15 is sleeved in the middle of the rotating drum 11, and a first servo motor 16 is arranged on the outside of the rotating drum 11. The power output end of the first servo motor 16 is connected to the first transmission belt 15 through a pulley. Under the driving action of the first servo motor 16, the first transmission belt 15 can drive the rotating drum 11 to rotate.

[0066] The rotating part 1 also includes a clamping mechanism 12 and a braking mechanism 13; the clamping mechanism 12 includes a pawl 121 and a locking clamp 122; there are multiple pawls 121, and the multiple pawls 121 are rotatably connected to the side wall of the rotating drum 11 through a pin 123, and the locking clamp 122 is threadedly connected to the outside of the rotating drum 11; the braking mechanism 13 is a multi-link structure, and can drive the brake pad 131 to wrap tightly around the outside of the locking clamp 122 through the multi-link structure. When the brake pad 131 wraps tightly around the locking clamp 122 and the rotating drum 11 rotates, the locking clamp 122 will generate radial displacement, pushing the pawl 121 to clamp the outer wall of the crucible body 52.

[0067] Specifically, such as Figure 17 and Figure 18 As shown, the rotating drum 11 has multiple claw mounting holes 112 on its side wall, arranged in a ring on the side wall of the rotating drum 11. In this embodiment, the multiple claw mounting holes 112 form two groups, respectively arranged at both ends of the rotating drum 11, and each group has three claw mounting holes 112. Figure 15 and Figure 16 The distribution shown is as follows. The chuck 121 has an L-shaped structure and is rotatably connected to the chuck mounting hole 112 via a pin 123. One support rod of the chuck 121 protrudes from the outside of the chuck mounting hole 112, serving as the power end for the lever structure. The locking clamp 122 has an internal thread on its inner side, and the outer wall of the rotating drum 11 has an external thread. The locking clamp 122 is threadedly connected to the outer wall of the rotating drum 11. In this embodiment, there are two locking clamps 122, each used to control one set of chucks 121. Therefore, the outer wall of the rotating drum 11 also has two sets of external threads 113, which are arranged in a forward and reverse interlocking configuration. When the locking clamp 122 is held in place by the braking mechanism 13 and cannot rotate, the first servo motor 16 drives the rotating drum 11 to rotate, thus switching the rotational motion of the rotating drum 11 to the axial motion of the locking clamp 122. Figure 18 As shown, the locking clamp 122 moves towards the clasp 121, pushing the clasp 121 so that the clasp 121 clamps the outer wall of the crucible body 52 of the crucible semi-finished product 5. Unlocking can be achieved by reversing the drive of the first servo motor 16 in the same manner.

[0068] In this embodiment, there are two braking mechanisms 13, each used to brake one of the two locking clamps 122, as shown below. Figure 15 As shown, the braking mechanism 13 includes a stand 132 disposed on the outside of the rotating drum 11. Each of the lower middle parts of both sides of the stand 132 has a first hinge seat 133. The first hinge seat 133 is connected to the lower middle part of the arc-shaped rod 134 through a hinge shaft. The bottom end of the arc-shaped rod 134 is connected to the brake pad 131 through a second hinge seat 135. The brake pad 131 is an arc-shaped plate adapted to the locking clamp 122.

[0069] It should be noted that the width of the brake pad 131 is greater than the width of the locking clamp 122. This is because, although the locking clamp 122 is restricted from rotation by the brake pad 131, it is not restricted from axial movement. Therefore, the width of the brake pad 131 needs to be greater than the linear travel distance of the locking clamp 122 so that rotational braking can be maintained during the axial movement of the locking clamp 122.

[0070] A brake block 136 is connected to one side of the upper part of the support frame 132 via a hinge shaft, and a fixed pulley 137 is installed on the other side. A brake rod 1361 is fixed on the brake block 136, extending away from the support frame 132. The top of the arc-shaped rod 134 near the brake block 136 is fixedly connected to the brake block 136 with a first steel cable 138, and the top of the arc-shaped rod 134 away from the brake block 136 is fixedly connected to the brake block 136 by a second steel cable 139 passing over the fixed pulley 137. The initial state after connection is as follows. Figure 15 As shown. At this time, there is a gap between the brake pad 131 and the locking clamp 122, and the rotation of the rotating drum 11 is not affected. When it is necessary to brake the locking clamp 122, the brake lever 1361 is pressed down, as shown. Figure 16 As shown, at this time, the brake block 136 tilts upward, causing the first steel cable 138 and the second steel cable 139 to tighten. The arc-shaped rod 134 rotates around the first hinge seat 133 as a fulcrum, causing the brake pad 131 to engage with the locking clamp 122, thus applying braking force. The greater the downward pressure of the brake lever 1361, the better the braking effect. When the brake lever 1361 is released, the braking is disengaged.

[0071] It should be noted that the braking mechanism 13 is designed to work in conjunction with the clamping mechanism 12. Braking only occurs when clamping or releasing the crucible semi-finished product 5. Only after braking can the locking clamp 122 move axially. Figure 16 The state during processing. When the drum 11 rotates during processing, the braking mechanism 13 is not activated, such as... Figure 15 The state shown will prevent interference with the rotation of the rotating drum 11.

[0072] Example 2:

[0073] In this embodiment, the cutting part 2 includes not only the double saw blade mechanism 21, but also the second turning tool mechanism 22. The second turning tool mechanism 22 is located outside the crucible bottom 53 of the crucible semi-finished product 5 and opposite to the double saw blade mechanism 21. The second turning tool mechanism 22 can cut radially from the outside of the crucible bottom 53. When the double saw blade mechanism 21 is cutting, it turns the cover flange 54 on the outer bottom surface of the crucible bottom 53.

[0074] To further optimize the above technical solution, the double saw blade mechanism 21 and the second cutting tool mechanism 22 are respectively installed on two moving platforms 23, which can realize axial and radial displacement drive relative to the crucible semi-finished product 5.

[0075] In this embodiment, the mobile platform 23 is a track-driven platform capable of X-axis and Y-axis movement. It can be driven by hydraulic cylinders or by lead screws and nuts, similar to the principle of existing conventional three-axis robots. These are conventional structures in the prior art and will not be elaborated further here. See also the following patents: CN108566042B, entitled "An Invention Patent for an XY Rapid Moving Platform with an External Y-axis Motor"; CN106426413B, entitled "An Invention Patent for a CNC Saw Y-axis Worktable Rotation Device"; and CN103388725B, entitled "A Single-Layer XY Direction Adjustment Platform," etc. Their principles are essentially the same. Since controlling the X-axis and Y-axis movement is not the focus of this invention, it will not be elaborated upon.

[0076] See appendix Figure 10 The double saw blade mechanism 21 is mounted on the mobile platform 23 and can achieve reciprocating motion in the direction of the arrow shown in the figure. The drive structure of the double saw blade mechanism 21 is also a conventional structure, with the second servo motor 211 as the power source, and the second transmission belt 212 transmitting the power to ultimately drive the double saw blades 213 to rotate.

[0077] See appendix Figure 11 The second cutting tool mechanism 22 is mounted on the mobile platform 23 and can achieve reciprocating motion in the direction of the arrow shown in the figure. The driving structure of the second cutting tool mechanism 22 is also a conventional structure, with the third servo motor 221 as the power source and the third transmission belt 222 for power transmission, ultimately driving the second cutting tool 223 to rotate. Through the feed of the second cutting tool 223, the machining and forming of the cover flange 54 is achieved.

[0078] During actual processing, the double saw blade mechanism 21 and the second cutting tool mechanism 22 simultaneously cut radially into the bottom 53 of the crucible semi-finished product 5. The double saw blade mechanism 21 begins to cut the cover 51 in layers, while the double saw blades 213 cut radially from the outside of the bottom 53. The saw blade closer to the rotating cylinder 11 is used for layer cutting, while the saw blade farther from the rotating cylinder 11 is used to grind the bottom surface. The two saw blades operate simultaneously, completing the cutting and grinding steps of the cover 51 together. At the same time, the second cutting tool 223 can complete the machining of the cover's protruding edge 54. Since the double saw blade mechanism 21 and the second cutting tool mechanism 22 cut in from both sides respectively, there is no interference, so the machining operations can be performed simultaneously.

[0079] Example 3:

[0080] During the cutting process of the lid 51, in order to prevent the crucible semi-finished product 5 from axial movement, this embodiment also provides a clamping mechanism 24, see [link to documentation]. Figure 19 and Figure 20The clamping mechanism 24 is installed above the rotating drum 11 and can control the support 242 to move toward the open end of the crucible semi-finished product 5 through the hydraulic cylinder 241, and clamp it to the open end of the crucible semi-finished product 5 through the clamping plate 243 connected on the support 242.

[0081] The clamping mechanism 24 is installed on the upright frame 132 of Embodiment 1. The clamping mechanism 24 includes a triangular support frame 244 fixed to the top of the upright frame 132. The top of the triangular support frame 244 has a third hinge seat 245. The top of the upright frame 132 facing the grinding part 3 has a fourth hinge seat 246. The fourth hinge seat 246 is connected to an L-shaped bracket 247 via a hinge shaft. The L-shaped bracket 247 is the bracket 242. A hydraulic cylinder 241 is movably connected between the rod connecting the L-shaped bracket 247 and the fourth hinge seat 246 and the third hinge seat 245. The other rod of the L-shaped bracket 247 points downward and is fixed to a connecting rod 248 by a nut. The end of the connecting rod 248 facing the rotating drum 11 is connected to a clamping plate 243 via a universal joint 249. Figure 19 As shown. In this embodiment, the clamping plate 243 is a disc.

[0082] Figure 19 The state is that the clamping plate 243 of the clamping mechanism 24 is lowered and clamps the open end of the crucible semi-finished product 5. In order to ensure that the clamping angle is appropriate, the clamping plate 243 is connected with a universal joint 249. This ensures that no matter what the lowering angle of the L-shaped bracket 247 is, the clamping plate 243 can fit with the open end of the crucible semi-finished product 5.

[0083] When clamping is not required, retract hydraulic cylinder 241 to lift L-shaped bracket 247, as shown. Figure 20 Then, the inner walls of the crucible body 52 and the bottom 53 of the crucible semi-finished product 5 can be ground.

[0084] Example 4:

[0085] See appendix Figure 21 The grinding section 3 also includes a slide rail drive platform 32, on which the first cutting tool mechanism 31 is mounted. The slide rail drive platform 32 is capable of axial and radial displacement drive relative to the crucible semi-finished product 5.

[0086] The first cutting tool mechanism 31 is mounted on the mobile platform 23, which can achieve the following: Figure 21 The reciprocating motion is shown in the figure. The drive structure of the first cutting tool mechanism 31 is also a conventional structure, powered by the fourth servo motor 311 and transmitted by the fourth transmission belt 312, which ultimately drives the first cutting tool 313 to rotate. Through the feed of the first cutting tool 313, the inner wall of the crucible body 52 and the bottom 53 of the crucible semi-finished product 5 is ground.

[0087] It should be noted that since the first cutting tool 223 needs to enter the crucible body 52 of the crucible semi-finished product 5, the tool holder of the first cutting tool 313 needs to be of a certain length so that it can enter.

[0088] The slide rail drive platform 32 in this embodiment has the same structural principle as the mobile platform 23 in embodiment 2, and will not be described again here.

[0089] Example 5:

[0090] To facilitate loading the crucible semi-finished product 5 into the rotating drum 11, this embodiment also provides a feeding section 4, see [link to relevant documentation]. Figure 6 and Figure 7 The feeding section 4 includes an arc-shaped base frame 41 located at one end of the crucible bottom 53 of the crucible semi-finished product 5. Rollers 42 are rotatably mounted on the arc-shaped base frame 41. The crucible semi-finished product 5 is placed on the arc-shaped base frame 41 and can be pushed to the inside of the rotating cylinder 11 under the action of external force.

[0091] like Figure 6 and Figure 7 As shown, the cross-section of the arc-shaped base 41 is arc-shaped, which can fit with the side wall of the crucible body 52 of the crucible semi-finished product 5. The rollers 42 are symmetrically arranged in two sets along the length of the arc-shaped base 41, so that the crucible semi-finished product 5 can be easily pushed into the rotating cylinder 11.

[0092] Example 6:

[0093] Based on Example 5, in order to ensure accurate positioning of the crucible semi-finished product 5 after it is loaded into the rotating cylinder 11, and to facilitate the alignment and processing of the double saw blade mechanism 21 and the second cutting tool mechanism 22, a positioning mechanism 43 is also connected to the arc-shaped base frame 41 in this embodiment. See Appendix Figure 6 , Figure 8 and Figure 9 The positioning mechanism 43 is a foldable linkage structure. When the positioning mechanism 43 is lifted and locked, it can position the bottom of the crucible 53. When the positioning mechanism 43 is unlocked and folded, it can be placed in the groove 411 of the arc-shaped base frame 41.

[0094] Specifically, the positioning mechanism 43 includes a first connecting rod 431, a second connecting rod 432, and a positioning rod 433; the arc-shaped base frame 41 is fixed to the base plate 45 by a support block 44; one end of the first connecting rod 431 is connected to the fifth hinge seat 451 on the base plate 45 via a hinge shaft; one end of the second connecting rod 432 is connected to the sixth hinge seat 452 on the base plate 45 via a hinge shaft; one end of the positioning rod 433 is hinged to the other end of the first connecting rod 431 via a hinge shaft; the middle part of the positioning rod 433 is hinged to the other end of the second connecting rod 432 via a hinge shaft; the connection end of the positioning rod 433 and the first connecting rod 431 has a 90° downward-curved bend 434; the first connecting rod 431 has a socket 435; a locking pin 436 is connected to the bend 434; the locking pin 436 can be inserted into the socket 435, and its inserted state is as follows. Figure 9 As shown, the first connecting rod 431, the second connecting rod 432, the base plate 45, and the positioning rod 433 form a quadrilateral structure. The structure is stable because the locking pin 436 is engaged and locked with the socket 435. At this time, the end of the positioning rod 433 away from the bend 434 is used to abut against the bottom of the crucible 53 for positioning. After positioning is completed, the locking pin 436 is opened, as shown... Figure 8 As shown, the quadrilateral structure can be folded.

[0095] To facilitate lifting and folding of the quadrilateral structure, a pull ring 437 is fitted on the positioning rod 433 for users to lift.

[0096] To further improve positioning accuracy, the end of the positioning rod 433 away from the elbow 434 is connected to a positioning head 438 by a thread. The positioning head 438 can be finely adjusted by screwing the thread.

[0097] It should be noted that when the crucible semi-finished product 5 is loaded, the positioning mechanism 43 is in a folded and retracted state, hidden in the groove 411 of the arc-shaped base 41. At this time, the crucible semi-finished product 5 is placed on the arc-shaped base 41, and then the crucible semi-finished product 5 is pushed into the rotating cylinder 11. After the crucible semi-finished product 5 is loaded into the rotating cylinder 11, the pull ring 437 is pulled up to lift the positioning mechanism 43. After the positioning mechanism 43 is lifted and locked by the locking pin 436, the position of the positioning head 438 should be the position of the crucible bottom 53. At this time, the position of the crucible semi-finished product 5 is adjusted according to the position of the positioning head 438. After the position of the crucible semi-finished product 5 is accurately adjusted, the crucible semi-finished product 5 is clamped by the jaw 121 through the cooperation of the clamping mechanism 12 and the braking mechanism 13. Then the locking pin 436 is unlocked, and the positioning mechanism 43 is folded back into the groove 411 of the arc-shaped base 41.

[0098] Example 7,

[0099] During the processing of the crucible semi-finished product 5, the bottom 53 and the cover 51 of the crucible are first cut and ground by the double saw blade mechanism 21 and the second cutting tool mechanism 22. The clamping mechanism 24 is used simultaneously during this process. After the cutting is completed, the bottom 53 and the cover 51 are also ground. Then, the clamping mechanism 24 is retracted, and the inner wall of the crucible body 52 and the bottom 53 of the crucible semi-finished product 5 are ground by the first cutting tool mechanism 31. Finally, only the opening edge of the crucible semi-finished product 5 remains unground. Therefore, this embodiment also provides a saw blade mechanism 33. (See attached diagram.) Figure 22 and attached Figure 23 The saw blade mechanism 33 is located outside the open end of the crucible semi-finished product 5, and can be radially cut in from the outside of the open end of the crucible body 52 to achieve grinding of the opening edge.

[0100] In this embodiment, the saw blade mechanism 33 is a manual grinding mechanism. Since the grinding of the open end of the crucible 52 is relatively simple and belongs to the final finishing work, a combination of manual and automatic structure is adopted in order to save costs.

[0101] Specifically, the saw blade mechanism 33 includes a base 331. Two bearing seats 332 are fixed at both ends of the top surface of the base 331. A light shaft 333 is fixed between the two bearing seats 332. A sleeve 334 is slidably connected to the light shaft 333. A handle 335 and a mounting bracket 336 are radially fixed to the sleeve 334. A fifth servo motor 337 and a support cylinder 338 are fixed to the mounting bracket 336. A rotating shaft is rotatably connected inside the support cylinder 338. One end of the rotating shaft is connected to a saw blade 339, and the other end of the rotating shaft is connected to the power output end of the fifth servo motor 337 via a pulley and belt drive. When the fifth servo motor 337 is started, it drives the saw blade 339 to rotate. By lifting the handle 335, the entire mounting bracket 336 is moved towards the open end of the crucible semi-finished product 5, thus grinding the opening edge of the crucible semi-finished product 5. When the mounting bracket 336 is retracted, it rests on the pad 3311 on the top surface of the base 331. Figure 22 As shown. When the saw blade mechanism 33 needs grinding, the handle 335 is lifted, causing the mounting bracket 336 to change angle, as shown. Figure 23 As shown.

[0102] It should be noted that the axial direction of the optical axis 33 is the same as that of the rotating cylinder 11, and the position of the mounting bracket 336 can be adjusted by moving the sleeve 334.

[0103] The saw blade 339 also cuts radially from the outside of the crucible semi-finished product 5 for grinding.
