Description

Technical Field

[0001] This invention relates to the field of volcanic rock core splitting technology, and more particularly to a volcanic rock core splitting device. Background Technology

[0002] In existing technologies, core splitting of volcanic rock samples (usually cylindrical cores) typically involves using a handheld cutting machine. However, this method is technically demanding, and because the sample is not fixed in place, a smooth cut surface cannot be guaranteed, resulting in unsatisfactory results. Furthermore, it increases the risk of accidents causing injury to workers, and such equipment often has insufficient power and low core splitting efficiency. To avoid these problems, existing technologies fix the sample during core splitting. However, the existing fixing methods... The method is relatively simple, such as setting up a semi-circular core groove, placing the sample in the core groove, and then cutting. Although this setting can achieve better results than direct cutting, it does not fix the sample. Therefore, in actual operation, the sample is not secure and shakes, resulting in poor cutting effect. Another fixing method is to use a clamping mechanism to clamp and fix the side of the sample to stabilize the sample during the cutting process. However, this method is prone to saw blade jamming during the cutting process, especially in the latter half of the cutting. In order to address the above problems, this invention proposes a volcanic rock core splitting device. Summary of the Invention

[0003] The purpose of this invention is to solve the problem of saw blade jamming caused by the method of fixing samples during the core splitting process of volcanic rock samples in the prior art, and to propose a volcanic rock core splitting device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A volcanic rock core splitting device includes a lifting cutting assembly for splitting volcanic rock samples, a clamping assembly for fixing volcanic rock samples, and a moving assembly for moving the clamping assembly. The clamping assembly includes two sets of clamping parts for clamping volcanic rock samples, the two sets of clamping parts are arranged opposite each other, and the bottoms of the two sets of clamping parts are hinged. The device also includes a driving assembly for controlling the opening and closing of the two sets of clamping parts.

[0005] Preferably, both the cutting component and the moving component are mounted on the frame, the clamping component is mounted on the moving component, and the driving component is mounted between the moving component and the clamping component.

[0006] Preferably, the moving component includes a fixed box and a lead screw assembly, the lead screw assembly being mounted on the frame, and the fixed box being driven to move by the lead screw assembly.

[0007] Preferably, the clamping part includes an arc-shaped plate and a clamping plate. Two clamping plates are provided and are located at both ends of the arc-shaped plate. A screw assembly is provided on the outer arc surface of the arc-shaped plate, and the two clamping plates achieve clamping action through the screw assembly.

[0008] Preferably, a connecting frame is fixedly provided at the bottom of the arc-shaped plate, and the bottom of the connecting frame is hinged to the upper part of the fixed box.

[0009] Preferably, the driving assembly includes a linkage assembly and a limiting assembly. The linkage assembly includes a connecting rod and a movable rod. The top end of the connecting rod is hinged to the arc-shaped plate, and the bottom end is hinged to the movable rod. The linkage assembly also includes a reset assembly, which is used to drive the movable rod to move downward.

[0010] Preferably, the reset assembly includes a fixed frame, a slide rod, and a tension spring. The fixed frame is fixedly disposed on the bottom surface of the fixed box, the slide rod is slidably disposed on the bottom of the fixed frame, the top end of the slide rod is fixedly connected to the movable rod, and the tension spring is sleeved on the slide rod to provide a downward force to the slide rod.

[0011] Preferably, the limiting component includes a guide rail with a ramp, a guide wheel, and a wheel frame. The wheel frame is fixedly mounted at the bottom end of the slide rod, the guide wheel is rotatably mounted at the lower part of the wheel frame, the guide rail is fixedly mounted at the bottom of the frame, and the guide wheel is in contact with the guide rail.

[0012] Preferably, the cutting assembly includes a base, a support arm, and a saw blade. The base is fixedly mounted on the top of the frame, one end of the support arm is rotatably connected to the base, and the saw blade is mounted on the other end of the support arm. The saw blade is driven to rotate by a drive device.

[0013] Preferably, it also includes a water spray assembly for cooling and dust suppression, the water spray assembly being disposed on the cutting assembly.

[0014] Compared with the prior art, the present invention provides a volcanic rock core splitting device, which has the following beneficial effects.

[0015] 1. This invention, through the setting of two sets of clamping parts, can clamp and fix both ends of the sample. During the cutting process, in conjunction with the driving component, it can reduce the problem of saw blade jamming. Thus, it can fix the sample while reducing the problem of saw blade jamming, thereby solving the problem of saw blade jamming that easily occurs in the fixation method of the sample during the core splitting of volcanic rock samples in the prior art.

[0016] 2. In this invention, the driving component can also drive the two clamping parts to move away from each other and open after the sample is cut, so that the two clamping parts can separate the divided sample and avoid unnecessary damage to the cut surface of the sample when the saw blade retracts.

[0017] 3. In this invention, the driving component can automatically change its state during the cutting process. That is, when the sample is most prone to shaking at the beginning of the cutting, the driving component can play an auxiliary clamping role on the side of the sample to prevent the sample from shaking. After a part is cut, the auxiliary clamping effect becomes ineffective, and only the clamping part is used for fixation, so as to avoid the problem of the saw blade getting stuck due to excessive clamping on the side of the sample.

[0018] 4. In this invention, after cutting a portion of the sample, the drive assembly, in cooperation with the clamping part, can apply a certain outward separating force to both sides of the sample cutting position, further reducing the probability of the saw blade jamming.

[0019] Other advantages, objectives and features of the invention will be set forth in part in the description which follows; and in part will be apparent to those skilled in the art upon examination of the following description; or may be learned from practice of the invention.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the invention in a schematic manner, and therefore only show the components relevant to the invention.

[0032] Please refer to Figures 1-10 A volcanic rock core splitting device includes a lifting cutting assembly for splitting volcanic rock samples, a clamping assembly for fixing volcanic rock samples, and a moving assembly for moving the clamping assembly. The clamping assembly includes two sets of clamping parts for clamping volcanic rock samples, the two sets of clamping parts are arranged opposite each other, and the bottoms of the two sets of clamping parts are hinged. It also includes a driving assembly for controlling the opening and closing of the two sets of clamping parts.

[0033] In a specific embodiment of the present invention, the lifting cutting component mainly functions to cut volcanic rock samples, achieving a core-splitting effect. Specifically, the cutting component cuts the sample, dividing it into two pieces along the axis. The clamping component is mainly used to fix the sample during the cutting process, preventing it from shaking or uncontrollable displacement, thus improving the cutting effect and reducing the risk during the cutting process. The moving component is mainly used to move the clamping component, thereby enabling a complete cut of the sample. This means the sample length is greater than the maximum cutting range of the cutting component. The moving component moves the clamping component, which in turn moves the sample, allowing it to be completely divided. Using the moving component to move the sample keeps the movement within a controllable range, without affecting the overall cutting effect. The driving component is mainly used for... The system controls the opening and closing of two clamping parts. One clamping part holds one half of the sample after it has been cut, and the other clamping part holds the other half. In the initial stage of cutting, the drive assembly moves the two clamping parts closer together to achieve an auxiliary clamping effect on the side of the sample. In the middle stage of cutting, the drive assembly applies a force to move the two clamping parts away from each other, thus losing the auxiliary clamping effect and preventing the sample from getting stuck on the saw blade 18. After cutting, the sample is divided into two halves. At this time, the drive assembly moves the two clamping parts open to separate the sample, preventing unnecessary damage to the cutting surface when the saw blade 18 retracts upward. It also allows the operator to clearly know that the cutting is complete and prevents the saw blade 18 from continuously cutting without contact. A gap is left between the two clamping parts, which is a gap that the saw blade 18 can pass through to prevent the saw blade 18 from cutting into the clamping parts.

[0034] Both the cutting component and the moving component are mounted on the frame 1. The clamping component is mounted on the moving component, and the driving component is mounted between the moving component and the clamping component. Specifically, the moving component can drive the clamping component to move horizontally, and in turn, it can drive the sample to move horizontally, thus adjusting the position of the sample to be cut and achieving complete cutting of the sample. The cutting part of the cutting component is located above the clamping component. During use, the cutting part of the cutting component can move up and down to achieve the effect of the cutting part contacting the sample for cutting, and the cutting depth can be adjusted.

[0035] The moving component includes a fixed box 9 and a lead screw assembly. The lead screw assembly is mounted on the frame 1, and the fixed box 9 is driven to move by the lead screw assembly.

[0036] Specifically, the lead screw assembly includes a lead screw 2 and a first limiting rod 10. The first limiting rod 10 is fixedly installed on the upper part of the frame 1. The lead screw 2 is rotatably installed on the upper part of the frame 1. Both ends of the fixed box 9 are fixedly provided with ear plates. One ear plate is slidably connected to the first limiting rod 10, and the other ear plate is threadedly connected to the lead screw 2. One end of the lead screw 2 extends out of the front end of the frame 1, and a handwheel 7 is fixedly installed at this end of the lead screw 2.

[0037] In use, by turning the handwheel 7, the lead screw 2 can be driven to rotate. Since the corresponding position of the fixed box 9 is threadedly connected to the lead screw 2, and due to the limitation of the first limit rod 10, the fixed box 9 can move horizontally along the first limit rod 10, thereby achieving the effect of moving the clamping component.

[0038] In other embodiments, the handwheel 7 can be replaced with an electric device, such as a servo motor, which drives the lead screw 2 to rotate, thereby achieving the effect of automatic movement.

[0039] In this solution, the fixed box 9, in addition to being used as a movable component, can also be used for sewage collection. The upper part of the fixed box 9 is provided with a groove to collect sewage (the sewage comes from the water needed to cool the saw blade 18 during the cutting process, and the smoke and dust generated during the cutting process. Water can reduce the smoke and dust from flying, and the water and smoke and dust will mix to form muddy water, which is the sewage mentioned in this solution). In order to divert the collected sewage, a drain pipe 25 is fixedly installed at the bottom of the fixed box 9. The drain pipe 25 is connected to the groove on the upper part of the fixed box 9. The collected sewage is diverted to a suitable location for discharge, such as a sewage tank, and then the sewage is diverted into the sewage tank for unified treatment later.

[0040] The clamping part includes an arc-shaped plate 13 and a clamping plate 12. There are two clamping plates 12, which are located at both ends of the arc-shaped plate 13. A screw assembly is provided on the outer arc surface of the arc-shaped plate 13. The two clamping plates 12 achieve clamping action through the screw assembly.

[0041] Specifically, the screw assembly includes a support 15, a screw 14, and a second limiting rod 11. The support 15 is fixedly mounted on the outer arc surface of the arc plate 13. The middle part of the screw 14 is rotatably connected to the support 15, and the ends of the screw 14 are threaded. There are two second limiting rods 11, which are fixedly mounted on both sides of the support 15. Two clamping plates 12 are slidably connected to the two second limiting rods 11, and are threadedly connected to the two sections of the screw 14. The two sections of the thread are opposite. In use, by rotating the screw 14, the two clamping plates 12 can be moved closer or further apart, thereby achieving the action of clamping or releasing using the two clamping plates 12. In order to facilitate the rotation of the screw 14, a hexagonal prism 3 is fixedly mounted in the middle position of the screw 14. When rotating the screw 14, a wrench can be used to assist in rotating the screw 14, thereby achieving the effect of clamping the sample.

[0042] A connecting frame 27 is fixedly installed at the bottom of the curved plate 13, and the bottom of the connecting frame 27 is hinged to the upper part of the fixed box 9. This arrangement can increase the distance between the curved plate 13 and the fixed box 9, thereby preventing the saw blade 18 from cutting the fixed box 9 during the cutting process.

[0043] The drive assembly includes a linkage assembly and a limiting assembly. The linkage assembly includes a link 8 and a movable rod 24. The top end of the link 8 is hinged to the arc plate 13, and the bottom end is hinged to the movable rod 24. The linkage assembly also includes a reset assembly, which is used to drive the movable rod 24 to move downward.

[0044] Specifically, in this design, one movable rod 24 corresponds to four connecting rods 8, and each end of the movable rod 24 corresponds to two connecting rods 8. The two connecting rods 8 at the same end correspond to two clamping parts. In this design, the top of the connecting rod 8 is hinged to the corresponding second limiting rod 11. In use, when the movable rod 24 moves downward, it can drive the connecting rod 8 to move downward. Since the top of the connecting rod 8 is hinged to the second limiting rod 11, it can drive the corresponding arc plate 13 to rotate. The rotation axis of the arc plate 13 is the hinge axis between the connecting frame 27 and the fixed box 9. Since the two clamping parts are arranged opposite each other, when the movable rod 24 moves downward, it can make the two arc plates 13 open (this state can be referred to in the appendix). Figure 10 Similarly, when the movable rod 24 moves upward, the two arc-shaped plates 13 are in a nearly closed state.

[0045] When the two curved plates 13 are open, the fixing box 9 below can be exposed. In this state, it is easy to clean the fixing box 9 and avoid the presence of sludge residue inside the fixing box 9.

[0046] The reset assembly includes a fixed frame 4, a slide rod 26, and a tension spring 23. The fixed frame 4 is fixedly mounted on the bottom surface of the fixed box 9. The slide rod 26 is slidably mounted on the bottom of the fixed frame 4. The top end of the slide rod 26 is fixedly connected to the movable rod 24. The tension spring 23 is sleeved on the slide rod 26 to provide a downward force to the slide rod 26. Specifically, the top end of the tension spring 23 is fixedly connected to the upper part of the slide rod 26, and the bottom end of the tension spring 23 is fixedly connected to the inner bottom surface of the fixed frame 4. The tension of the tension spring 23 applies a downward force to the slide rod 26.

[0047] The limiting assembly includes a ramped guide rail 5, a guide wheel 6, and a wheel frame 28. The wheel frame 28 is fixedly mounted at the bottom end of the slide rod 26, and the guide wheel 6 is rotatably mounted at the lower part of the wheel frame 28. The guide rail 5 is fixedly mounted at the bottom of the frame 1, and the guide wheel 6 is in contact with the guide rail 5. Specifically, the front section of the guide rail 5 is horizontal, the middle section is ramped, and the rear section is also horizontal, with the front section being higher than the rear section. During operation, the height position of the guide wheel 6 is adjusted using the guide rail 5, thereby changing the height position of the slide rod 26, which in turn changes the height position of the movable rod 24, thus controlling the opening and closing of the two clamping parts.

[0048] The cutting assembly includes a base 19, a support arm 21, and a saw blade 18. The base 19 is fixedly mounted on the top of the frame 1. One end of the support arm 21 is rotatably connected to the base 19, and the saw blade 18 is mounted on the other end of the support arm 21. The saw blade 18 is driven to rotate by a drive device. Specifically, the drive device is a motor 22, which is fixedly mounted on the support arm 21 near the base 19. The saw blade 18 is mounted on the end of the support arm 21 via a rotating shaft. The output end of the motor 22 is connected to the rotating shaft by a pulley assembly, i.e., one pulley is mounted on the output shaft of the motor 22, and the other pulley is mounted on the rotating shaft. The two pulleys are connected by a belt. In use, the motor 22 and the pulley assembly drive the saw blade 18 to rotate, thereby realizing the cutting operation.

[0049] To facilitate adjustment of the saw blade 18 height, a handle 16 is fixedly installed on the support arm 21. During use, the height of the saw blade 18 can be controlled by holding the handle 16. To improve cutting safety, a saw blade guard is also provided. The saw blade guard is fixedly installed on the support arm 21 and covers the saw blade 18. To prevent damage to the fixing box 9 caused by the saw blade 18 being too low, a limit block 20 is fixedly installed on the base 19 to limit the rotation range of the support arm 21 and prevent the saw blade 18 from being too low.

[0050] It also includes a water spray assembly for cooling and dust suppression, which is installed on the cutting assembly. Specifically, the water spray assembly includes a nozzle 17 and a water pump. The nozzle 17 is fixedly installed on the saw blade guard in the cutting assembly, and the nozzle 17 faces the saw blade 18. The nozzle 17 is connected to the outlet of the water pump through a water pipe, and the water pump's intake is connected to a water source through another water pipe. In use, the water pump draws water and then sprays it out from the nozzle 17 to cool the saw blade 18 and reduce the smoke and dust generated during cutting, thus avoiding the generation of a large amount of smoke and dust during dry cutting.

[0051] Workflow: Under normal conditions, the moving component is positioned close to the cutting component, and the saw blade 18 is in a raised state, meaning the saw blade 18 is higher than the clamping component (a spring or torsion spring can be installed between the support arm 21 and the base 19 to maintain the raised state of the saw blade 18; this is a common setting and will not be elaborated here, but can be referenced in the context of a benchtop cutting machine). At this time, the guide wheel 6, under the action of the tension spring 23, contacts the rear section of the guide rail 5, and the two clamping parts are in an open state (this state can be referred to in the appendix). Figure 10When core-splitting a volcanic rock sample (cylindrical core, with the inner arc surface of the arc plate 13 matching the annular surface of the sample), the sample is placed inside any of the arc plates 13, and then the two ends of the sample are clamped and fixed using the clamping parts on the arc plate 13. Then, the moving assembly drives the clamping assembly forward (i.e., away from the cutting assembly). During this movement, the guide wheel 6 slowly moves upward along the slope. As the guide wheel 6 moves upward, it drives the wheel frame 28, the slide rod 26, and the movable rod 24 upward. When the movable rod 24 moves upward, it drives the two arc plates 13 closer together. When the guide wheel 6... Upon reaching the front section of guide rail 5, the two arc-shaped plates 13 are nearly closed. At this time, the two arc-shaped plates 13 assist in clamping the sides of the sample. Then, the clamping part on the other arc-shaped plate 13 is used to clamp and fix both ends of the sample. Then, the motor 22 is started to rotate the saw blade 18, and the water pump is started to spray water. Then, one hand holds the handle 16 and presses down on the saw blade 18, so that the saw blade 18 cuts downward from the rear section of the sample until it cuts through. At this time, the support arm 21 will abut against the limit block 20 to prevent the saw blade 18 from moving further down. After cutting through, the other hand turns the handwheel 7 to slow down the moving component. Slowly move towards the rear, causing the clamping assembly and sample to move backward, cutting the uncut portion of the sample. During this backward movement, when the guide wheel 6 passes the ramp, it separates from the guide rail 5, meaning the guide wheel 6 becomes suspended. At this point, the tension spring 23 applies a downward force to the slide rod 26, causing the two arc-shaped plates 13 to tend to open. However, since the sample is not completely cut and the clamping part is still holding the sample, the arc-shaped plates 13 cannot complete the opening action, thus losing their auxiliary clamping effect and reducing the probability of jamming the saw blade 18. Simultaneously, it can apply a certain separation force to the two clamping parts, further reducing the risk of jamming the saw blade. With the probability of the saw blade 18 being cut, after the cutting is completed, under the action of the tension spring 23, the two arc plates 13 will open, and the two clamping parts will also separate, so that the cut sample is also separated, and the separated sample is located in the two arc plates 13 respectively. At this time, the guide wheel 6 will fall on the rear section of the guide rail 5. When the sample is separated, the worker can clearly know that the cutting is completed, and then lift the saw blade 18 to reset it. When lifting the saw blade 18, since the sample has been separated, it will not touch the sample when lifting the saw blade 18. Then release the clamping part, remove the separated sample, and complete the operation.
