Description

Technical Field

[0001] This invention relates to the field of die-casting technology, specifically to an aluminum baking pan production equipment and its production method. Background Technology

[0002] Aluminum baking pans are kitchen baking utensils made from aluminum alloys (such as ADC12, A380 and other die-cast aluminum alloys) through a die-casting machine.

[0003] In the prior art, Chinese utility model with publication number CN215090624U discloses an aluminum baking pan die-casting mold. During use, the resulting baking pan has an ideal flatness of the iron sheet, a beautiful riveted joint, and the iron sheet and aluminum baking pan can fit tightly without gaps, thus ensuring the die-casting effect and production quality of the baking pan.

[0004] However, in traditional die-casting machines, when changing the mold, the positioning structure around the mold requires multiple adjustments by operators to ensure precise positioning between the fixed and moving molds. This mold change process is complex, and post-change positioning is difficult. Therefore, this invention proposes an aluminum baking tray production equipment and method to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an aluminum baking pan production equipment and production method to solve the problems mentioned in the background art, such as the complex mold replacement process and the difficulty in positioning after replacement in traditional die casting machines.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an aluminum baking pan production device, comprising: A mounting base and a sliding base are respectively provided with a fixed mold and a moving mold, and the two are compatible with each other; The outer side of the fixed mold is provided with sliding blocks for positioning. Two sliding blocks are provided as a group, and there are two groups in total. The two groups of sliding blocks are distributed in the X-axis direction and the Z-axis direction, respectively. The mounting bracket is fixed inside the mounting base. An X-axis double-ended screw and a Z-axis double-ended screw are rotatably mounted on one side of the mounting bracket and are offset from each other. The X-axis double-ended screw drives two sliding blocks of one group to move synchronously in opposite directions, and the Z-axis double-ended screw drives two sliding blocks of another group to move synchronously in opposite directions. The X-axis double-ended screw is movably sleeved on the outside, with a driven spur gear sliding along its length. The Z-axis double-ended screw is fixed on the outside, with a driven bevel gear. A transmission shaft parallel to the X-axis double-ended screw is provided between the X-axis and Z-axis double-ended screws. One end of the transmission shaft is fixed with a driving bevel gear, which meshes with the driven bevel gear. A driving spur gear is provided on one side of the driving bevel gear. The driving spur gear is movably sleeved on the outside of the transmission shaft and slides along its length. After sliding away from the driving bevel gear, the driving spur gear meshes with the driven spur gear. A thrust spring is provided between the driving spur gear and the driving bevel gear.

[0007] Preferably, a drive shaft is provided at the other end of the transmission shaft, and a polygonal insert is fixed at the end of the drive shaft. The polygonal insert is stepped, and the dimension of the end of the polygonal insert away from the drive shaft is larger than the dimension of the other end. A polygonal slot adapted to the polygonal insert is opened inside the other end of the transmission shaft, and the length of the polygonal slot is larger than that of the polygonal insert. A second thrust spring is provided in the inner cavity of one end of the polygonal slot, and the two ends of the second thrust spring abut against the inner wall of one end of the polygonal slot and one end of the polygonal insert, respectively.

[0008] Preferably, the drive shaft is rotatably mounted on one side of the mounting frame via a bracket, a driven wheel is fixedly sleeved on the outer side of the drive shaft, and a driving wheel is connected to the outer side of the driven wheel via a belt drive. The driving wheel is controlled to rotate by a drive motor mounted on the mounting frame.

[0009] Preferably, the inner wall of the driven spur gear is provided with a plurality of anti-rotation grooves arranged in a ring array, and the outer side of the X-axis double-ended screw is fixed with an anti-rotation boss corresponding to and adapted to the plurality of anti-rotation grooves. An annular stop is provided on one side of the driven spur gear and the annular stop is fixedly sleeved on the outer side of the X-axis double-ended screw. A return spring is provided between the annular stop and the driven spur gear, and a retaining spring is provided on the other side of the driven spur gear. An annular groove for the retaining spring to engage is provided on the surface of the X-axis double-ended screw.

[0010] Preferably, a baffle is fixed on one side of the driving spur gear, and a bushing is fixed in the middle of the other side of the driving spur gear. The bushing is movably sleeved on the outside of the transmission shaft. An adjusting plate is rotatably sleeved on the outside of the bushing. An avoidance groove is opened on the surface of the mounting bracket. One end of the adjusting plate is movably connected to the avoidance groove. A cylinder parallel to the transmission shaft is fixed on the other side of the mounting bracket. The movable end of the cylinder is fixedly connected to one end of the adjusting plate.

[0011] Preferably, the inner wall of the driving spur gear is fixed with a plurality of strip-shaped protrusions arranged in a ring array, and the surface of the transmission shaft is provided with strip-shaped grooves that correspond to and fit the plurality of strip-shaped protrusions. When the driving spur gear slides away from the driving bevel gear to one end of the strip-shaped groove, the driving spur gear is just fully engaged with the driven spur gear.

[0012] Preferably, a mold positioning plate is provided on one side of the sliding block, and a sleeve plate is fixed at one end of the mold positioning plate. The four mold positioning plates are connected end to end in sequence, and the four mold positioning plates are respectively attached to the four sides of the mold.

[0013] Preferably, a connecting slider is fixed in the middle of the mold positioning plate, a connecting groove is provided on one side of the sliding block for the connecting slider to slide, a guide groove is provided on the surface of the mounting base, a guide slider is fixed on the sliding block and slidably connected to the guide groove, a connecting frame is fixed on the surface of the guide slider, an internal threaded sleeve is fixed in the middle of the connecting frame, and four internal threaded sleeves are respectively threaded onto both ends of the X-axis double-ended screw and both ends of the Z-axis double-ended screw.

[0014] A method for producing an aluminum baking pan, using the aforementioned aluminum baking pan production equipment, specifically includes the following steps: Step 1: Place the fixed mold in the center of the front of the mounting base, and clamp and position the fixed mold by controlling the position of the four mold positioning plates. Step 2: Start the external hydraulic cylinder to drive the sliding seat to move closer to the mounting base until the moving mold on the sliding seat presses and fits tightly against the fixed mold; Step 3: Inject molten metal between the fixed mold and the moving mold. After cooling and solidification, separate the sliding seat from the mounting seat. Step 4: Use a robotic arm to remove the molded parts from the fixed mold.

[0015] Preferably, in step one, the cylinder drives the adjusting plate to move, which in turn drives the active spur gear to move. When the active spur gear moves closer to the active bevel gear, the active spur gear and the driven spur gear separate. The rotation of the transmission shaft drives the Z-axis double-ended screw to rotate through the meshing between the active bevel gear and the driven bevel gear. When the active spur gear moves away from the active bevel gear, the active spur gear and the driven spur gear mesh, and the active bevel gear and the driven bevel gear mesh. The rotation of the transmission shaft simultaneously drives the X-axis double-ended screw and the Z-axis double-ended screw to rotate. When the active spur gear continues to move away from the active bevel gear, the active spur gear drives the driven spur gear and the transmission shaft to move until the active bevel gear and the driven bevel gear separate. At this time, the rotation of the transmission shaft only drives the X-axis double-ended screw to rotate.

[0016] Compared with the prior art, the beneficial effects of the present invention are: This invention features an X-axis double-ended screw and a Z-axis double-ended screw inside a mounting base. A driven spur gear is slidably mounted on the X-axis double-ended screw, and a driven bevel gear is fixed on the Z-axis double-ended screw. The X-axis and Z-axis double-ended screws are staggered and connected by a transmission shaft parallel to the X-axis double-ended screw. A driving bevel gear is fixed to one end of the transmission shaft, and a driving spur gear is mounted on one side of the driving bevel gear. A thrust spring is positioned between the two. The driving spur gear is slidably mounted on the outside of the transmission shaft. When the driving spur gear is slid close to the driving bevel gear, the driving bevel gear meshes with the driven bevel gear, and the driving spur gear disengages from the driven spur gear. At this time, rotation of the transmission shaft can independently drive the Z-axis double-ended screw to rotate, moving the driving spur gear away from the driving bevel gear. When the bevel gear slides, the driving spur gear meshes with the driven spur gear, and the driving bevel gear remains meshed with the driven bevel gear. At this time, the rotation of the transmission shaft can simultaneously drive the X-axis double-ended screw and the Z-axis double-ended screw to rotate. When the driving spur gear continues to slide away from the driving bevel gear, the driving spur gear meshes with the driven spur gear, and the driving bevel gear separates from the driven bevel gear. At this time, the rotation of the transmission shaft can drive the X-axis double-ended screw to rotate independently. Therefore, by adjusting the position of the driving spur gear, this device can control the X-axis double-ended screw and the Z-axis double-ended screw to rotate independently or simultaneously. This makes it easier for operators to clamp and position the fixed mold in the X-axis and Z-axis directions, thereby facilitating the replacement of the fixed mold and ensuring more accurate positioning of the fixed mold.

[0019] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit 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.

[0020] Please see Figures 1 to 11 The present invention provides a technical solution: Example 1: An aluminum baking pan production equipment, comprising: a mounting base 1, a sliding base 2, and a mounting frame 5.

[0021] Specifically, a fixed mold 11 and a movable mold 21 are respectively provided on the mounting base 1 and the sliding base 2, and the two are compatible with each other. The mounting base 1 and the fixed mold 11 maintain their fixed positions, while the sliding base 2 can move closer to or away from the mounting base 1, thereby driving the movable mold 21 to close or open with the fixed mold 11. Secondly, sliding blocks 4 are provided on the outside of the fixed mold 11 for positioning. Two sliding blocks 4 are provided as a group, and there are a total of two groups. The fixed mold 11 has a square structure. The two groups of sliding blocks 4 are distributed in the X-axis direction and the Z-axis direction, respectively. The four sliding blocks 4 are located around the fixed mold 11, which can simultaneously achieve positioning of the fixed mold 11 in the X-axis and Z-axis, so as to avoid the fixed mold 11 from shifting its position and failing to keep in correspondence with the moving mold 21. Furthermore, the mounting bracket 5 is fixed inside the mounting base 1. An X-axis double-ended screw 6 and a Z-axis double-ended screw 7 are rotatably mounted on one side of the mounting bracket 5. The X-axis double-ended screw 6 and the Z-axis double-ended screw 7 are each fixed in position by a fixed bracket. The X-axis double-ended screw 6 and the Z-axis double-ended screw 7 can only rotate and will not shift in position. They are also staggered and will not interfere with each other. The X-axis double-ended screw 6 drives two sliding blocks 4 of one group to move synchronously in opposite directions. The Z-axis double-ended screw 7 drives two sliding blocks 4 of another group to move synchronously in opposite directions. The two sliding blocks 4 in the X-axis direction are driven to move by the X-axis double-ended screw 6, and the two sliding blocks 4 in the Z-axis direction are driven to move by the Z-axis double-ended screw 7. In addition, a driven spur gear 61 is movably sleeved on the outer side of the X-axis double-ended screw 6, sliding along its length. The driven spur gear 61 can only move along the length of the X-axis double-ended screw 6 and will not rotate relative to the X-axis double-ended screw 6. However, the X-axis double-ended screw 6 and the driven spur gear 61 can rotate synchronously. A driven bevel gear 71 is fixed on the outer side of the Z-axis double-ended screw 7. The driven bevel gear 71 itself does not move, but when it rotates, it can drive the Z-axis double-ended screw 7 to rotate. A transmission shaft 8 parallel to the X-axis double-ended screw 6 is provided between the X-axis double-ended screw 6 and the Z-axis double-ended screw 7. A driving bevel gear 82 is fixed at one end of the transmission shaft 8. Furthermore, the driving bevel gear 82 meshes with the driven bevel gear 71. Therefore, when the transmission shaft 8 rotates, the meshing between the driving bevel gear 82 and the driven bevel gear 71 drives the Z-axis double-headed screw 7 to rotate. A driving spur gear 81 is provided on one side of the driving bevel gear 82. The driving spur gear 81 is movably sleeved on the outside of the transmission shaft 8 and slides along its length. The driving spur gear 81 and the transmission shaft 8 can only move relative to each other along the length of the transmission shaft 8; they do not rotate relative to each other. Therefore, when the transmission shaft 8 rotates, it can also drive the driving spur gear 81 to rotate accordingly. After the driving spur gear 81 slides away from the driving bevel gear 82, it meshes with the driven spur gear 61. Figure 8As shown, in the current state, the driving spur gear 81 and the driven spur gear 61 are separated. When the transmission shaft 8 rotates, it only drives the Z-axis double-ended screw 7 to rotate. However, when the driving spur gear 81 moves away from the driving bevel gear 82 along the length of the transmission shaft 8, the driving spur gear 81 can mesh with the driven spur gear 61. Since the positions of the transmission shaft 8 and the driving bevel gear 82 remain unchanged, the rotation of the transmission shaft 8 can simultaneously drive the X-axis double-ended screw 6 and the Z-axis double-ended screw 7 to rotate. When the transmission shaft 8 moves and drives the driving bevel gear 82 to separate from the driven bevel gear 71, the transmission shaft 8... If the rotation continues, it will no longer be able to drive the Z-axis double-ended screw 7 to rotate. Therefore, this device can control the rotation of the X-axis double-ended screw 6 and the Z-axis double-ended screw 7 by controlling the position of the driving spur gear 81 and the transmission shaft 8. In addition, a thrust spring 813 is provided between the driving spur gear 81 and the driving bevel gear 82. When the driving spur gear 81 moves away from the driving bevel gear 82, the thrust generated by the thrust spring 813 makes the two always tend to move away from each other. At this time, the driving bevel gear 82 still maintains meshing with the driven bevel gear 71, while the driving spur gear 81 meshes with the driven spur gear 61.

[0022] To drive the transmission shaft 8 to rotate, this application further includes a drive shaft 84 at the other end of the transmission shaft 8. A polygonal insert 841 is fixed to the end of the drive shaft 84. The polygonal insert 841 is stepped, and the dimension of the end of the polygonal insert 841 away from the drive shaft 84 is larger than the dimension of the other end. A polygonal slot 842 adapted to the polygonal insert 841 is opened inside the other end of the transmission shaft 8, and the length of the polygonal slot 842 is larger than that of the polygonal insert 841. Figure 10 As shown, the drive shaft 84 and the transmission shaft 8 can move relative to each other by a certain distance along the length of the transmission shaft 8, thereby enabling them to move closer or further apart. The cooperation between the polygonal insert 841 and the polygonal slot 842 can guide the relative movement between the transmission shaft 8 and the drive shaft 84 on the one hand, and prevent relative rotation between the transmission shaft 8 and the drive shaft 84 on the other hand. That is to say, the transmission shaft 8 and the drive shaft 84 always maintain synchronous rotation. In addition, a thrust spring 843 is provided in the inner cavity of one end of the polygonal slot 842. The two ends of the thrust spring 843 abut against the inner wall of one end of the polygonal slot 842 and one end of the polygonal insert 841, respectively. The thrust spring 843 provides thrust, so that the drive shaft 84 and the transmission shaft 8 always tend to move away from each other.

[0023] In order to drive the drive shaft 84 to rotate, the drive shaft 84 of this application is rotatably mounted on one side of the mounting bracket 5 via a bracket. The drive shaft 84 itself is fixed in position and can only rotate. A driven wheel 85 is fixedly sleeved on the outer side of the drive shaft 84. A driving wheel 86 is connected to the outer side of the driven wheel 85 via a belt drive. The driving wheel 86 is controlled to rotate by a drive motor 87 mounted on the mounting bracket 5. When the drive motor 87 is working, it drives the driving wheel 86 to rotate, and then drives the drive shaft 84 to rotate through the belt drive, thereby driving the drive shaft 84 and the transmission shaft 8 to rotate.

[0024] To limit the travel of the driven spur gear 61, this application also includes multiple anti-rotation grooves 611 arranged in a ring array on the inner wall of the driven spur gear 61, and anti-rotation bosses 612 corresponding to and adapted to the multiple anti-rotation grooves 611 fixed on the outer side of the X-axis double-ended screw 6, such as... Figure 9 As shown, the mutual cooperation between the anti-rotation groove 611 and the anti-rotation boss 612 can prevent relative rotation between the driven spur gear 61 and the X-axis double-ended screw 6, and ensure that the driven spur gear 61 and the X-axis double-ended screw 6 can move relative to each other in the length direction of the X-axis double-ended screw 6. An annular stop 62 is provided on one side of the driven spur gear 61 and is fixedly sleeved on the outside of the X-axis double-ended screw 6. A return spring 63 is provided between the annular stop 62 and the driven spur gear 61. The return spring 63 is always in a compressed state, ensuring that the driven spur gear 61 and the annular stop 62 always tend to move away from each other. A retaining ring 65 is provided on the other side of the driven spur gear 61. An annular groove 64 for the retaining ring 65 to engage is opened on the surface of the X-axis double-ended screw 6. The retaining ring 65 and the annular stop 62 are located on both sides of the driven spur gear 61, and can be used to limit the sliding stroke of the driven spur gear 61 on the X-axis double-ended screw 6.

[0025] To drive the driving spur gear 81 to move relative to the drive shaft 8 along its length, this application further includes a baffle 811 fixed on one side of the driving spur gear 81. When the driving spur gear 81 moves away from the driving bevel gear 82, the driving spur gear 81 first meshes with the driven spur gear 61. Then, the baffle 811 abuts against the side of the driven spur gear 61, so that when the driving spur gear 81 continues to move away from the driving bevel gear 82, the driving spur gear 81 will not disengage from the driven spur gear 61, but will instead drive the driven spur gear 61 to move synchronously. A bushing 812 is fixed in the middle of the other side of the driving spur gear 81, and the bushing 812 is movably sleeved on the outside of the drive shaft 8. An adjusting plate 83 is rotatably sleeved on the outside of the bushing 812. The adjustment plate 83 rotates relative to the bushing 812 without separating from it. Therefore, by controlling the adjustment plate 83 to move along the length of the drive shaft 8, the drive spur gear 81 can be driven to move relative to the drive shaft 8. An avoidance groove 51 is provided on the surface of the mounting bracket 5. One end of the adjustment plate 83 is movably connected to the avoidance groove 51. The avoidance groove 51 can prevent the adjustment plate 83 from colliding with the mounting bracket 5 when it moves. A cylinder 52 parallel to the drive shaft 8 is fixed on the other side of the mounting bracket 5. The movable end of the cylinder 52 is fixedly connected to one end of the adjustment plate 83. When the cylinder 52 is working, it extends and retracts, thereby driving the adjustment plate 83 to move, which facilitates the adjustment of the position of the drive spur gear 81.

[0026] To separate the driving bevel gear 82 from the driven bevel gear 71, this application further includes multiple strip-shaped protrusions arranged in a circular array fixed on the inner wall of the driving spur gear 81, and strip-shaped grooves corresponding to and fitting the multiple strip-shaped protrusions on the surface of the transmission shaft 8, such as... Figure 10 and Figure 11 As shown, the engagement of the strip-shaped protrusion and the strip-shaped groove not only prevents relative rotation between the driving spur gear 81 and the drive shaft 8, but also limits the relative travel distance between them. When the driving spur gear 81 slides away from the driving bevel gear 82 to one end of the strip-shaped groove, it is fully engaged with the driven spur gear 61. At this point, as the driving spur gear 81 continues to move away from the driving bevel gear 82, the strip-shaped protrusion is already located at one end of the strip-shaped groove, thus preventing further rotation. When the drive shaft 8 moves relative to the drive shaft 8, the driving spur gear 81 will drive the drive shaft 8 to move together. Since the drive shaft 8 and the driving bevel gear 82 are relatively fixed, when the driving spur gear 81 continues to move, it will drive the drive shaft 8 and the driving bevel gear 82 to move together, thereby separating the driving bevel gear 82 from the driven bevel gear 71. In this state, the driving spur gear 81 is engaged with the driven spur gear 61, and the driving bevel gear 82 is separated from the driven bevel gear 71. Therefore, when the drive shaft 8 rotates, it can only drive the X-axis double-ended screw 6 to rotate. Based on the information described above, it can be seen that the device has three different states during the movement of the driving spur gear 81: ① When the driving spur gear 81 is located close to the driving bevel gear 82, the driving spur gear 81 is separated from the driven spur gear 61, and the driving bevel gear 82 is engaged with the driven bevel gear 71. At this time, the rotation of the transmission shaft rod 8 only drives the Z-axis double-headed screw 7 to rotate. ② When the driving spur gear 81 moves away from the driving bevel gear 82 to the middle position of the stroke of the driving spur gear 81, the driving spur gear 81 meshes with the driven spur gear 61, and the driving bevel gear 82 meshes with the driven bevel gear 71. At this time, the rotation of the transmission shaft rod 8 drives the X-axis double-headed screw 6 and the Z-axis double-headed screw 7 to rotate simultaneously. ③ When the driving spur gear 81 is located far away from the driving bevel gear 82, the driving spur gear 81 meshes with the driven spur gear 61, and the driving bevel gear 82 separates from the driven bevel gear 71. At this time, the rotation of the transmission shaft rod 8 only drives the X-axis double-headed screw 6 to rotate.

[0027] To position the fixed mold 11, this application further includes a mold positioning plate 3 provided on one side of the sliding block 4. When the sliding block 4 moves, it can drive the mold positioning plate 3 to move synchronously, thereby adjusting the position of the mold positioning plate 3. A sleeve plate 31 is fixed to one end of the mold positioning plate 3. The four mold positioning plates 3 are sequentially connected end-to-end, and the four mold positioning plates 3 respectively conform to the four sides of the fixed mold 11. Figure 3 As shown, the four mold positioning plates 3 are connected end to end in sequence, and a rectangular cavity is formed between the four mold positioning plates 3, which can be used to install and place the fixed mold 11. When the four mold positioning plates 3 are brought together, the mold positioning plates 3 can position the fixed mold 11, thereby preventing the fixed mold 11 from shifting its own position.

[0028] To ensure that the X-axis double-ended screw 6 and the Z-axis double-ended screw 7 can drive the corresponding sliding block 4 to slide during rotation, this application also includes a connecting slider 32 fixed in the middle of the mold positioning plate 3. A connecting groove 41 is provided on one side of the sliding block 4 for the connecting slider 32 to slide. The cooperation between the connecting slider 32 and the connecting groove 41 allows relative sliding between the mold positioning plate 3 and the sliding block 4, thereby ensuring that the four mold positioning plates 3 can converge without being restricted by the sliding block 4. A guide groove 12 is provided on the surface of the mounting base 1, and a guide slider 42 is fixed on the sliding block 4 and slidably connected to the guide groove 12. The cooperation between the guide slider 42 and the guide groove 12 is used to guide the sliding direction of the sliding block 4. To limit the direction and prevent the sliding block 4 from separating from the mounting base 1, a connecting frame 43 is fixed on the surface of the guide slider 42. A strip-shaped through groove is opened at the bottom of the guide slide groove 12, allowing the connecting frame 43 to pass through and slide. An internal threaded sleeve 44 is fixed in the middle of the connecting frame 43. Four internal threaded sleeves 44 are respectively threaded onto the two ends of the X-axis double-ended screw 6 and the two ends of the Z-axis double-ended screw 7. The setting of the internal threaded sleeves 44 ensures that when the X-axis double-ended screw 6 and the Z-axis double-ended screw 7 rotate, they can drive the sliding block 4 at their respective positions to move, thereby controlling the two mold positioning plates 3 in the X-axis direction to move closer (or farther) to each other, and controlling the other two mold positioning plates 3 in the Z-axis direction to move closer (or farther) to each other.

[0029] This invention also discloses a method for producing an aluminum baking pan, using the aforementioned aluminum baking pan production equipment, specifically including the following steps: Step 1: Place the fixed mold 11 in the center of the front of the mounting base 1, and clamp and position the fixed mold 11 by controlling the position of the four mold positioning plates 3. Step 2: Start the external hydraulic cylinder to drive the sliding seat 2 to move closer to the mounting seat 1 until the moving mold 21 on the sliding seat 2 presses and fits tightly against the fixed mold 11; Step 3: Inject molten metal between the fixed mold 11 and the moving mold 21. After cooling and solidification, separate the sliding seat 2 from the mounting seat 1. Step 4: Use a robotic arm to remove the molded parts from the fixed mold 11.

[0030] To explain in detail how to control the positions of the four mold positioning plates 3, in step one of this application, the adjusting plate 83 is moved by the cylinder 52, which in turn drives the active spur gear 81 to move. When the active spur gear 81 moves closer to the active bevel gear 82, the active spur gear 81 separates from the driven spur gear 61, and the rotation of the transmission shaft 8 drives the Z-axis double-ended screw 7 to rotate through the meshing between the active bevel gear 82 and the driven bevel gear 71. When the active spur gear 81 moves away from the active bevel gear 82, the active spur gear 81 meshes with the driven spur gear 61, and the active bevel gear 82 meshes with the driven bevel gear 71. The rotation of the transmission shaft 8 simultaneously drives the X-axis double-ended screw 6 and the Z-axis double-ended screw 7 to rotate. When the active spur gear 81 continues to move away from the active bevel gear 82, the active spur gear 81 drives the driven spur gear 61 and the transmission shaft 8 to move until the active bevel gear 82 separates from the driven bevel gear 71. At this time, the rotation of the transmission shaft 8 only drives the X-axis double-ended screw 6 to rotate.

[0031] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
