Description

Technical Field

[0001] This invention relates to the field of milling machine technology, and in particular to a fully automatic milling machine with portable sample limiting function. Background Technology

[0002] A milling machine is a specialized piece of equipment used for processing the surface of metal, alloy, or other material samples. It quickly prepares a flat and clean sample surface through milling to meet the needs of chemical composition analysis (such as spectral detection), metallographic observation, or mechanical property testing. It is widely used in industries such as metallurgy, machinery manufacturing, and geological exploration.

[0003] In the metallurgical industry, milling machines are commonly used for surface treatment during metal sample preparation. Milling removes oxide layers, burrs, unevenness, or contamination from the metal sample surface, ensuring a smooth and uniform surface for subsequent chemical composition analysis (such as spectral analysis) or physical property testing. When a milling cutter needs to be reused within a short period, it is usually placed on the milling machine without being disassembled for convenient future use. However, leaving milling cutters exposed to air can lead to the following problems: rust: metal milling cutters (especially high-speed steel) are prone to rust in humid environments, affecting cutting accuracy; contamination: dust or chemicals (such as sulfides) in the air adhere to the cutting edge, contaminating the sample during subsequent use. Summary of the Invention

[0004] Therefore, it is necessary to provide a fully automatic milling machine with a portable sample limiting function that can protect the milling cutter when the milling machine is not in operation, in order to address the above-mentioned technical problems.

[0005] The present invention provides a fully automatic sample milling machine with sample portability and limiting function, comprising a frame and a storage plate movably mounted on the frame, and further comprising:

[0006] The lifting frame is threadedly installed on one side of the frame body;

[0007] A rotating cylinder is movably mounted at the bottom of the lifting frame;

[0008] A disc is fixedly installed at the end of the rotating cylinder away from the lifting frame;

[0009] Through holes are arranged in a ring array on the bottom of the disk, and the number of through holes is set to be multiple.

[0016] In one embodiment, the shielding assembly includes two baffles that abut against each other and are rotatably connected to the inner wall of the transverse groove. Both baffles have external teeth on one side and engage with each other for transmission. A vertical rod is fixedly inserted through one side of one of the baffles and is rotatably connected to the inner wall of the transverse groove.

[0017] In one embodiment, the drive assembly includes a curved groove formed on the outer side of the cylinder, a limit rod movably disposed within the curved groove, and the other end of the limit rod being fixedly connected to the cylinder.

[0018] In one embodiment, a drive gear is fixedly installed on the side of the vertical rod away from the baffle, and an incomplete gear is fixedly sleeved on the outer side of the cylinder, the incomplete gear meshing with the drive gear for transmission.

[0019] In one embodiment, a positioning gear is fixedly sleeved on the cylinder above the incomplete gear. A fixed rod is movably arranged inside the rotating cylinder. One end of the fixed rod is fixedly connected to the bottom of the lifting frame, and the other end movably passes through the disc. A circular plate is fixedly arranged inside the disc and at its end. A limiting gear is arranged on the outside of the circular plate. The positioning gear meshes with the limiting gear for transmission. A collar is fixedly arranged on the outside of the fixed rod. An internal tooth is fixedly arranged on the inside of the collar. The positioning gear meshes with the internal tooth for transmission.

[0020] In one embodiment, the incomplete gear is fixedly connected to the inner wall of the disk by a torsion spring, and the cylinder is movably disposed inside the torsion spring.

[0021] In one embodiment, the cylinder has axially symmetrically arranged movable grooves on both sides of its bottom. A movable cylinder is slidably arranged in the movable groove, and a movable rod is movably arranged in the movable cylinder. A wiping pad is fixedly arranged at the end of the movable rod away from the movable cylinder. The wiping pad slides against the surface of the milling cutter. The movable cylinder is connected to the inner wall of the movable groove by a positioning spring.

[0022] In one embodiment, a ring is fixedly sleeved on the outer side of the moving rod, the ring is slidably connected to the moving cylinder, and the ring is connected to the inner wall of the moving cylinder by a return spring, the return spring being movably sleeved on the outer side of the moving rod.

[0023] In one embodiment, a vertical plate is axially symmetrically fixed at the position of the through hole on the disk. The vertical plate has a vertical groove, an arc groove, and a straight groove, which are interconnected.

[0045] The following is combined with Figures 1-10 This invention describes a fully automatic milling machine with a portable sample limiting function.

[0046] like Figures 1-7 As shown, in one embodiment, a fully automatic sample milling machine with sample portability and positioning function includes a frame 1 and a storage plate 2 movably mounted on the frame 1, and further includes:

[0047] The lifting frame 3 is threadedly installed on one side of the frame 1;

[0048] Rotating cylinder 4 is movably installed at the bottom of the lifting frame 3;

[0049] The disc 5 is fixedly installed at the end of the rotating cylinder 4 away from the lifting frame 3;

[0050] Through holes 51 are arranged in a ring array at the bottom of the disk 5, and the number of holes is set to multiple.

[0051] The cylinder 6 is movably installed inside the disk 5 and communicates with the through hole 51;

[0052] The cylinder 7 is movably installed inside the cylindrical tube 6 and is slidably connected to the through hole 51;

[0053] The milling cutter 10 is rotatably mounted on the bottom of the cylinder 7;

[0054] A transverse groove 52 is provided inside the disk 5 and communicates with the through hole 51.

[0055] The shielding component 8 is disposed in the transverse groove 52 and is used to shield the through hole 51;

[0056] The drive assembly 9, located on the cylinder 6, is used to drive the milling cutter 10 to move.

[0057] Specifically, the sample to be milled is placed on the placement plate 2 for positioning. In this application, the number of through holes 51 is set to four. The type of milling cutter 10 installed at the bottom of each cylinder 7 can be set to be different. In this way, multiple types of milling cutters 10 can be set in the disc 5. The appropriate milling cutter 10 is selected for milling according to the type of sample to be processed. In the initial state, only one milling cutter 10 in the disc 5 will move down to the outside of the through hole 51 to facilitate the milling of the sample. The corresponding blocking component 8 of the milling cutter 10 is in the open state, and the other three blocking components 8 are in the closed state. The corresponding milling cutter 10 is located in the through hole 51. The blocking component 8 blocks the through hole 51, which can effectively protect the milling cutter 10. When it is located outside the through hole 51 If the milling cutter 10 is unsuitable for the sample, it needs to be switched. Rotate the rotating cylinder 4 clockwise. The rotation of the rotating cylinder 4 drives the rotating disk 5 to rotate. During the rotation of the disk 5, another through hole 51 will be moved to the top of the placement plate 2. The rotation angle is 90 degrees at a time. During the rotation, the driving component 9 on the cylinder 6 drives the cylinder 7 and the milling cutter 10 corresponding to the through hole 51 to move downward. During this process, the shielding component 8 in the transverse groove 52 must first remove the shielding of the through hole 51, so that the milling cutter 10 can move to the outside of the through hole 51. Then, the lifting frame 3 moves downward along the frame 1. The descent of the lifting frame 3 will cause the milling cutter 10 to move downward and contact the sample surface. The rotation of the milling cutter 10 can remove impurities from the sample surface, which is convenient for subsequent analysis. If the milling cutter 10 is still not suitable after rotating 90 degrees, then rotate it another 90 degrees until a suitable milling cutter 10 is selected.

[0058] See Figure 6 and Figure 7 As shown, in this embodiment, the shielding component 8 includes two baffles 81. The two baffles 81 abut against each other and are rotatably connected to the inner wall of the transverse groove 52. Both baffles 81 are provided with external teeth 82 on one side and the two mesh with each other for transmission. A vertical rod 83 is fixedly provided through one side of one of the baffles 81 and is rotatably connected to the inner wall of the transverse groove 52.

[0059] Specifically, when the milling cutter 10 is located inside the through hole 51, the two baffles 81 are centered and abut against each other, which can block the through hole 51 and prevent dust in the air from entering the through hole 51. When switching the milling cutter 10, the disc 5 rotates, and during the rotation, the vertical rod 83 rotates. The rotation of the vertical rod 83 will drive the external tooth 82 on the same side to rotate, so that the two baffles 81 move away from each other and the baffles 81 no longer block the through hole 51. Then the cylinder 7 and the milling cutter 10 move downwards, and the milling cutter 10 moves to the outside of the through hole 51, which is convenient for milling the sample.

[0060] See Figure 6 and Figure 7 As shown, in this embodiment, the driving component 9 includes a curved groove 91 formed on the outer side of the cylinder 6, a limiting rod 92 is movably disposed in the curved groove 91, and the other end of the limiting rod 92 is fixedly connected to the cylinder 7.

[0061] Specifically, when it is necessary to switch the corresponding milling cutter 10, the disc 5 drives the cylinder 6 to revolve and rotate on its own axis. The rotation of the cylinder 6 drives the curved groove 91 to rotate. Since the curved groove 91 is equipped with a limit rod 92, the rotation of the cylinder 6 will drive the cylinder 7 and the milling cutter 10 to move downward along the cylinder 6. The milling cutter 10 will eventually move to the outside of the through hole 51. Similarly, the cylinder 6 will rotate in the opposite direction to move the cylinder 7 and the milling cutter 10 upward to the initial position.

[0062] See Figures 6-8 As shown, in this embodiment, a drive gear 11 is fixedly installed on the side of the vertical rod 83 away from the baffle 81, and an incomplete gear 12 is fixedly sleeved on the outer side of the cylinder 6. The incomplete gear 12 meshes with the drive gear 11 for transmission.

[0063] Specifically, when switching the corresponding milling cutter 10, rotating the cylinder 6 causes the cylinder 7 and the milling cutter 10 to move downwards. At the same time, the rotation of the cylinder 6 also causes the incomplete gear 12 to rotate. The rotation of the incomplete gear 12 causes the drive gear 11 and the vertical rod 83 to rotate. The rotation of the vertical rod 83 causes the two baffles 81 to move away from each other, so as not to block the through hole 51. After the two baffles 81 move away from each other, the part of the incomplete gear 12 with the gear no longer meshes with the drive gear 11. The drive gear 11 and the vertical rod 83 stop rotating. At this time, the cylinder 6 continues to rotate, and the cylinder 7 and the milling cutter 10 continue to move downwards. At this time, the baffles 81 no longer abut, so they will not affect the descent of the milling cutter 10. The milling cutter 10 finally moves to the outside of the through hole 51 to mill the sample. Similarly, when the cylinder 6 rotates in the opposite direction, the milling cutter 10 will first move above the baffles 81, and then the two baffles 81 will abut to block the through hole 51.

[0064] See Figure 3 and Figure 6As shown, in this embodiment, the cylindrical tube 6 is fixedly fitted with a positioning gear 13 above the incomplete gear 12. A fixed rod 14 is movably arranged inside the rotating tube 4. One end of the fixed rod 14 is fixedly connected to the bottom of the lifting frame 3, and the other end movably passes through the disc 5. A circular plate 15 is fixedly arranged inside the disc 5 and at its end. A limiting gear 16 is arranged on the outer side of the circular plate 15. The positioning gear 13 meshes with the limiting gear 16 for transmission. A collar 17 is fixedly arranged on the outer side of the fixed rod 14. An internal tooth 18 is fixedly arranged on the inner side of the collar 17. The positioning gear 13 meshes with the internal tooth 18 for transmission.

[0065] Specifically, when the milling cutter 10 is not matched with the sample to be processed, the rotating cylinder 4 is rotated 90 degrees clockwise. The rotating cylinder 4 drives the disc 5 and the cylinder 6 to rotate synchronously. The rotation of the cylinder 6 drives the positioning gear 13 to rotate. During the rotation, it will mesh with the limiting gear 16 set on the outer side of the disc 15, so that the cylinder 6 can rotate on its own axis while revolving with the disc 5. The rotation of the cylinder 6 will drive the incomplete gear 12 to rotate, which can drive the vertical rod 83 to rotate. The rotation of the vertical rod 83 can make the baffles 81 move away from each other, and the milling cutter 10 can move to the outside of the through hole 51. When the milling cutter 10 is used up, If the milling cutter 10 is still mismatched, rotate the disk 5 in the same direction again. The positioning gear 13 corresponding to the milling cutter 10 will rotate to one side again. During this process, the positioning gear 13 will mesh with the internal teeth 18 provided on the collar 17, realizing the reverse rotation of the positioning gear 13. This enables the reverse rotation of the cylinder 6 and the incomplete gear 12. After the milling cutter 10 moves back into the through hole 51, the two baffles 81 below will again abut against the through hole 51 to block it. The fixing rod 14 provides support for the collar 17 and remains stationary during the rotation of the disk 5.

[0066] See Figure 3 , Figure 6 and Figure 7 As shown, in this embodiment, the incomplete gear 12 is fixedly connected to the inner wall of the disk 5 by a torsion spring 19, and the cylinder 6 is movably disposed inside the torsion spring 19.

[0067] Specifically, the rotation of cylinder 6 will drive the incomplete gear 12 to rotate, enabling the milling cutter 10 to move downward to the outside of the through hole 51. During this process, the torsion spring 19 will twist and store energy. When the positioning gear 13 meshes with the internal teeth 18 of the collar 17 to achieve the reverse rotation of the positioning gear 13, the torsion spring 19 will gradually return to its original state and also drive the positioning gear 13 to rotate in the opposite direction, which can drive the cylinder 6 to rotate in the opposite direction to the initial state.

[0068] See Figures 8-10As shown, in this embodiment, the cylinder 7 has axially symmetrically provided moving grooves 71 on both sides of its bottom. A moving cylinder 20 is slidably disposed in the moving groove 71. A moving rod 21 is movably disposed in the moving cylinder 20. A wiping pad 22 is fixedly disposed at the end of the moving rod 21 away from the moving cylinder 20. The wiping pad 22 slides against the surface of the milling cutter 10. The moving cylinder 20 is connected to the inner wall of the moving groove 71 by a positioning spring 23.

[0069] Specifically, when the milling cutter 10 is located inside the through hole 51, the wiping pads 22 on both sides are flush with the surface of the milling cutter 10 and located on both sides of the milling cutter 10. As the milling cutter 10 moves outward from the through hole 51, the moving cylinder 20 moves along the moving groove 71 towards the direction closer to the milling cutter 10. The movement of the moving cylinder 20 will drive the moving rod 21 and the wiping pad 22 to move. The wiping pad 22 slides along the surface of the milling cutter 10 to clean the surface of the milling cutter 10. During this process, the positioning spring 23 will be compressed. Then the force applied to the moving cylinder 20 will be removed. Under the action of the positioning spring 23, the moving cylinder 20, the moving rod 21 and the wiping pad 22 will be pushed back to the initial position.

[0070] See Figures 10-11 As shown, in this embodiment, a ring 24 is fixedly sleeved on the outer side of the moving rod 21. The ring 24 is slidably connected to the moving cylinder 20. The ring 24 is connected to the inner wall of the moving cylinder 20 by a return spring 25. The return spring 25 is movably sleeved on the outer side of the moving rod 21.

[0071] Specifically, when the milling cutter 10 moves downward, the wiping pad 22 moves back and forth along the surface of the milling cutter 10 to clean the milling cutter 10. However, the fact that the wiping pad 22 is flush with the milling cutter 10 will affect the milling of the sample by the milling cutter 10. After the wiping pad 22 moves back to the initial position once, it moves towards the moving cylinder 20 to push the wiping pad 22. The wiping pad 22 drives the moving rod 21 and the ring 24 to move into the moving cylinder 20. The wiping pad 22 is no longer flush with the milling cutter 10 and its height is higher than that of the milling cutter 10. It will not affect the milling of the sample by the milling cutter 10. During this process, the return spring 25 will be compressed. After the milling cutter 10 finishes processing, the force applied to the wiping pad 22 is released. Under the action of the return spring 25, the moving rod 21, the ring 24 and the wiping pad 22 return to the initial position.

[0072] See Figures 4-5 and Figures 8-9As shown, in this embodiment, the disc 5 is axially symmetrically fixed with a vertical plate 26 at the position of the through hole 51. The vertical plate 26 has a vertical groove 261, an arc groove 262 and a straight groove 263, which are interconnected. The bottom of the wiping pad 22 is fixedly provided with a positioning rod 27, which is slidably connected with the vertical groove 261, the arc groove 262 and the straight groove 263.

[0073] Specifically, when the cylinder 7 and the milling cutter 10 move downwards together, they will cause the wiping pad 22 and the positioning rod 27 to move together. When the milling cutter 10 moves to the outside of the through hole 51, the limiting rod 92 will slide with the vertical groove 261 opened in the vertical plate 26. When it slides down along the vertical groove 261 into the arc groove 262, the positioning rod 27 will move laterally back and forth under the action of the arc groove 262 and then return to the initial position. During this process, the wiping pad 22 will slide along the surface of the milling cutter 10 to clean it. Then the cylinder 7 and the milling cutter 10 continue to move downwards, and the positioning rod 27 will move to the bottom of the straight groove 263. Due to the abutment force of the inner wall of the straight groove 263, the positioning rod 27 will move upwards in the relative downward direction, causing the wiping pad 22 and the moving rod 21 to move upwards, compressing the return spring 25. The wiping pad 22 moves above the milling cutter 10, so as not to affect the milling cutter 10's processing of the sample. At this time, the bottom of the cylinder 7 is just flush with the through hole 51 and will not collide with the vertical plate 26.

[0074] See Figure 1 As shown in this embodiment, clamping plates 28 are axially symmetrically and movably arranged at both ends of the storage plate 2.

[0075] Specifically, the clamping plates 28 set on both sides of the placement plate 2 can clamp and limit the sample, ensuring the stability of the sample during the milling process.

[0076] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0077] The above-described embodiments are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
