Description

Technical Field

[0001] This utility model relates to the field of cutting machine technology, specifically to a cutting machine with easily adjustable clamps. Background Technology

[0002] Flame cutting machines use fuels such as acetylene, which, when mixed with oxygen, are ignited in a nozzle to create an extremely high-temperature flame. This flame can reach temperatures of 3300°C (6000°F), enough to melt or oxidize most metals. During the cutting process, the metal workpiece is placed on the worktable according to a pre-designed template or computer-aided design (CAD) file. The operator uses a handheld cutting nozzle to focus the flame on the metal surface and then cuts the metal according to a preset contour by controlling the movement of the nozzle. As the metal oxidizes at high temperatures, and oxygen is simultaneously supplied through the cutting nozzle, the metal surface is oxidized and melted, ultimately forming the desired cut shape.

[0003] A flame cutting machine is mentioned in an existing Chinese patent (authorization announcement number: CN215468685U). It includes a nozzle, a fixing device for fixing the nozzle, and a driving device for driving the nozzle. The fixing device includes a support frame, a sleeve located on the support frame, a guide rod slidably connected to the sleeve, a connecting rod located on the guide rod, and a roller located on the guide rod. The sleeve is slidably connected to the support frame, one end of the connecting rod is connected to the guide rod, and the other end is connected to the nozzle. The roller is rotatably connected to the guide rod. An elastic element is provided inside the sleeve to limit the stroke of the guide rod. The flame cutting machine designed in this application, through the roller and elastic element, facilitates the adjustment of the nozzle height according to the shape of the sheet material, making it easier to cut the allowance of sheet material with different shapes, expanding the application range of the flame cutting machine, and improving the cutting accuracy of the flame cutting machine.

[0004] Existing flame cutting machines require the steel to be fixed to the ground with clamps before the machine is placed on the surface. The machine then moves over the steel while the cutting head cuts the steel below it. However, cutting with only one cutting head cannot cut the next steel plate in one go. At least two cuts along the previous cut line are required to remove the steel plate. This cutting method is too simplistic and reduces the cutting efficiency of the machine. In addition, the existing machine is difficult to adjust the cutting head, which limits it to round cuts and prevents it from making bevel cuts. Utility Model Content

[0005] The purpose of this application is to address the problem that the existing cutting methods are too simplistic, which reduces the cutting efficiency of the device, and that the existing devices are difficult to adjust the cutting head to achieve bevel cutting. This application provides a cutting machine with an adjustable clamp.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A cutting machine with an adjustable clamp includes a machine body, an adjustment box mounted on the upper end of the machine body, a bidirectional screw rotatably connected inside the adjustment box, clamp frames fixedly connected to both sides of the adjustment box, the clamp frames rotatably connected to the ends of the bidirectional screw, a movable ring threaded to both ends of the bidirectional screw, a depth rod installed inside the movable ring, a cutting head hinged to the lower end of the depth rod, a movable wheel hinged to the lower end of the machine body, and an adjustment structure provided on the upper end of the machine body.

[0008] By adopting the above technical solution, when the device cuts steel, it is first placed on the surface of the steel. Then, the bidirectional screw is rotated to drive the moving rings to move in opposite directions. The movement of the two moving rings drives the cutting heads on both sides to move. The distance between the cutting heads is adjusted according to the diameter of the steel plate to be cut. Then, the fixed position of the depth rod on the moving ring is adjusted according to the depth of the steel plate. This leads to the adjustment of the distance between the cutting head and the steel, thereby adjusting the cutting capacity of the device when cutting steel of different thicknesses. This allows the device to use two sets of cutting heads simultaneously, greatly improving the cutting efficiency of the device. By adjusting the position and height of the cutting heads, the device can be adjusted according to the different dimensions and thicknesses of the steel when cutting, improving the versatility of the device when cutting steel of different thicknesses.

[0009] Furthermore, the adjustment structure includes an adjustment motor fixedly connected to the upper end of the adjustment box, a bevel gear one fixedly connected to the output end of the adjustment motor through the adjustment box, and a bevel gear two fixedly connected to the outer surface of the bidirectional screw, wherein the bevel gear one and the bevel gear two mesh with each other.

[0010] By adopting the above technical solution, the starting adjustment motor drives the first bevel gear to rotate, which in turn drives the second bevel gear to rotate, thereby driving the bidirectional screw to rotate, and thus the bidirectional screw moves.

[0011] Furthermore, a hydraulic cylinder is fixedly connected to the upper end of the machine body, the telescopic end of the hydraulic cylinder is fixedly connected to the adjustment box, a guide column is fixedly connected inside the machine body, and the outer surface of the guide column is slidably connected to the adjustment box.

[0012] By adopting the above technical solution, the hydraulic cylinder is then activated to push the adjustment box to move, so that the adjustment box moves along the guide column, thereby driving the clamp frames on both sides of the adjustment to move, and further adjusting the distance between the cutting head on both sides of the machine body and the machine body.

[0013] Furthermore, a limiting plate is fixedly connected to the lower end of the moving ring, and a sliding groove is provided inside the clamp frame, with the limiting plate slidably connected to the sliding groove.

[0014] By adopting the above technical solution, the moving ring is limited by the limiting plate when it moves, making its movement more stable.

[0015] Furthermore, a telescopic column is fixedly connected to one end of the movable ring, and a clamping plate is fixedly connected to the end of the telescopic column. Clamping strips are fixedly connected to both the clamping plate and the inside of the movable ring. Several clamping grooves are formed on the outer surface of the depth rod, and the shape of the clamping grooves is adapted to the clamping strips.

[0016] By adopting the above technical solution, the clamping plate moves along the telescopic column to the moving ring until both sides of the clamping groove are limited by the clamping strip, fixing the depth rod inside the moving ring. This also allows the cutting head at its lower end to be adjusted to the horizontal height of the steel when the depth rod is adjusted.

[0017] Furthermore, a mounting screw is rotatably connected to one side of the movable ring, and the outer surface of the mounting screw is threadedly connected to the clamping plate.

[0018] By adopting the above technical solution, rotating the mounting screw causes the clamping plate to move away from the moving ring along the telescopic column, which in turn causes the clamping strip to move away from the clamping groove, thus freeing it from limiting the clamping groove.

[0019] Furthermore, a sliding column is slidably connected inside the depth rod, and a semi-circular limiting block is fixedly connected to the end of the sliding column. Several circumferentially distributed semi-circular limiting grooves are opened on one side of the cutting head. The semi-circular limiting grooves are adapted to the shape of the semi-circular limiting block. A spring is sleeved on the outside of the sliding column, and the two ends of the spring are fixedly connected to the semi-circular limiting block and the depth rod, respectively.

[0020] By adopting the above technical solution, when the required steel is beveled, the rotating cutting head moves along the depth rod of the sliding column, and the cutting head abuts against the semi-circular limiting block, causing it to move along the depth rod and contract the spring. This continues until the cutting head rotates and moves the next semi-circular limiting groove to the semi-circular limiting block. At this time, the spring returns to its original position and pushes the semi-circular limiting block into the current semi-circular limiting groove, limiting the semi-circular limiting groove and keeping the cutting head at the current rotation angle. When cutting is then performed, the beveling cutting can be achieved on the cutting part.

[0021] Furthermore, a track is installed at the lower end of the movable wheel, a plate is fixedly connected to one end of the track, and a slot is provided at the other end of the track. The shape of the plate and the slot are adapted to each other, and threaded grooves are provided on the surface of both the plate and the slot.

[0022] By adopting the above technical solution, when cutting steel, the track is first placed on the steel, and then the insert plate at the end of another track is inserted into the slot of the previous track, so that the threaded groove between the insert plate and the slot is connected to each other, and the bolt is rotated to connect the insert plate and the slot. This makes the device more convenient to splice the track and facilitates the movement of the machine body on the track.

[0023] In summary, this application includes at least one of the following beneficial effects;

[0024] 1. In this application, when the device needs to cut steel, the moving ring is limited by the limiting plate during movement, making its movement more stable. This causes the moving ring to drive the depth rod to move, so that the position of the cutting head is initially adjusted and the distance between the two cutting heads is adjusted. Then, the hydraulic cylinder is activated to push the adjustment box to move, which in turn moves the clamp frames on both sides of the adjustment, further adjusting the distance between the cutting heads on both sides of the machine body and the machine body. This makes the adjustment of the cutting head position more flexible during the use of the device, which can be used for cutting plates of different sizes. Moreover, the simultaneous use of two sets of cutting heads greatly improves the cutting efficiency of the device and reduces the time required for cutting.

[0025] 2. In this application, when steel needs to be cut, first rotate the mounting screw to move the clamping plate away from the moving ring along the telescopic column. This causes the clamping strip to move away from the clamping groove, thus removing its limitation on the clamping groove. Then, move the depth rod up and down to align the clamping groove at another location with the clamping strip inside the moving ring. Then, turn the mounting screw to move the clamping plate along the telescopic column towards the moving ring until both sides of the clamping groove are limited by the clamping strip, fixing the depth rod inside the moving ring. This also allows the cutting head at its lower end to be adjusted to be level with the steel when the depth rod is adjusted, thereby enabling cutting... When cutting steel plates, the cutting head can be adjusted according to the thickness of the steel plate to ensure the cutting efficiency of the device. When the required steel is to be cut at an angle, the cutting head is rotated. As the cutting head rotates, it abuts against the semi-circular limiting block, causing it to move along the depth rod of the sliding column and contracting the spring. This continues until the cutting head rotates and moves the next semi-circular limiting groove to the semi-circular limiting block. At this time, the spring returns to its original position and pushes the semi-circular limiting block to move into the current semi-circular limiting groove, limiting the semi-circular limiting groove and keeping the cutting head at the current rotation angle. Cutting at this point will then be able to perform a bevel cut on the cutting part. Attached Figure Description

[0036] The following will be based on the embodiments of this utility model. Figures 1-8 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0037] Reference Figure 1 and Figure 2This utility model provides a technical solution: a cutting machine with an adjustable clamp, comprising a machine body 1, an adjustment box 5 installed on the upper end of the machine body 1, a bidirectional screw 13 rotatably connected inside the adjustment box 5, clamp frames 2 fixedly connected to both sides of the adjustment box 5, the clamp frames 2 rotatably connected to the ends of the bidirectional screw 13, a moving ring 9 threadedly connected to both ends of the bidirectional screw 13, a depth rod 8 installed inside the moving ring 9, a cutting head 4 hinged to the lower end of the depth rod 8, a moving wheel 3 hinged to the lower end of the machine body 1, and an adjustment structure provided on the upper end of the machine body 1.

[0038] When the device cuts steel, it is first placed on the surface of the steel. Then, the bidirectional screw 13 is rotated to drive the moving rings 9 to move in opposite directions. The movement of the moving rings 9 on both sides drives the cutting heads 4 on both sides to move. The distance between the cutting heads 4 is adjusted according to the diameter of the steel plate to be cut. Then, the fixed position of the depth rod 8 on the moving rings 9 is adjusted according to the depth of the steel plate. This leads to the adjustment of the distance between the cutting head 4 and the steel, thereby adjusting the cutting ability of the device when cutting steel of different thicknesses. This allows the device to use two sets of cutting heads 4 simultaneously, greatly improving the cutting efficiency of the device. By adjusting the position and height of the cutting head 4, the device can be adjusted according to the different dimensions and thicknesses of the steel when cutting, improving the versatility of the device when cutting steel of different thicknesses.

[0039] Reference Figure 2 and Figure 3 , Figure 6 The adjustment structure includes an adjustment motor 6 fixedly connected to the upper end of the adjustment box 5. A bevel gear 20 is fixedly connected to the output end of the adjustment motor 6 through the adjustment box 5. A bevel gear 21 is fixedly connected to the outer surface of the bidirectional screw 13, and the bevel gear 20 meshes with the bevel gear 21. A hydraulic cylinder 12 is fixedly connected to the upper end of the machine body 1. The telescopic end of the hydraulic cylinder 12 is fixedly connected to the adjustment box 5. A guide column 11 is fixedly connected inside the machine body 1, and the outer surface of the guide column 11 is slidably connected to the adjustment box 5. A limiting plate 16 is fixedly connected to the lower end of the moving ring 9. A sliding groove is provided inside the clamp frame 2, and the limiting plate 16 is slidably connected to the sliding groove.

[0040] When the device needs to cut steel, the adjusting motor 6 is started, driving the bevel gear 20 to rotate. This causes the bevel gear 20 to rotate, which in turn drives the double screw 13 to rotate. The double screw 13 then drives the moving ring 9 to move in opposite directions. As the moving ring 9 moves, it is limited by the limiting plate 16, making its movement more stable. This causes the moving ring 9 to move the depth rod 8, allowing for initial adjustment of the position of the cutting head 4 and the distance between the two cutting heads 4. Next, the hydraulic cylinder 12 is started, pushing the adjusting box 5 to move. This causes the adjusting box 5 to move along the guide column 11, thereby moving the clamp frames 2 on both sides of the adjusting box. This further adjusts the distance between the cutting head 4 and the machine body 1. This makes the adjustment of the cutting head 4 position more flexible during use, making it suitable for cutting plates of different sizes. The simultaneous use of two sets of cutting heads 4 greatly improves the cutting efficiency of the device and reduces the time required for cutting.

[0041] Reference Figure 3 and Figure 4 , Figure 5 , Figure 7 One end of the moving ring 9 is fixedly connected to a telescopic column 15, and the end of the telescopic column 15 is fixedly connected to a clamping plate 14. Clamping strips 18 are fixedly connected to both the clamping plate 14 and the inside of the moving ring 9. Several clamping grooves 19 are formed on the outer surface of the depth rod 8, and the shape of the clamping grooves 19 is adapted to the shape of the clamping strips 18. A mounting screw 17 is rotatably connected to one side of the moving ring 9, and the outer surface of the mounting screw 17 is threaded to the clamping plate 14. A sliding column 24 is slidably connected inside the depth rod 8, and a semi-circular limiting block 23 is fixedly connected to the end of the sliding column 24. Several circumferentially distributed semi-circular limiting grooves 22 are formed on one side of the cutting head 4, and the semi-circular limiting grooves 22 are adapted to the shape of the semi-circular limiting block 23. A spring 25 is sleeved on the outside of the sliding column 24, and both ends of the spring 25 are fixedly connected to the semi-circular limiting block 23 and the depth rod 8, respectively.

[0042] When steel needs to be cut, first rotate the mounting screw 17 to move the clamping plate 14 away from the moving ring 9 along the telescopic column 15. This causes the clamping bar 18 to move away from the clamping groove 19, so that it no longer limits the clamping groove 19. Then, move the depth rod 8 up and down to align the other clamping groove 19 with the clamping bar 18 inside the moving ring 9. Then, turn the mounting screw 17 to move the clamping plate 14 along the telescopic column 15 towards the moving ring 9 until both sides of the clamping groove 19 are limited by the clamping bar 18, fixing the depth rod 8 inside the moving ring 9. This also allows the cutting head 4 at its lower end to be adjusted to be at the same horizontal level as the steel when the depth rod 8 is adjusted, thus making the cutting... When cutting steel plates, the cutting head 4 can be adjusted according to the thickness of the steel plate to ensure the cutting efficiency of the device. When the required steel is to be cut at an angle, the cutting head 4 is rotated. As the cutting head 4 rotates, it abuts against the semi-circular limiting block 23, causing it to move along the sliding column 24 into the depth rod 8 and contracting the spring 25. This continues until the cutting head 4 rotates and moves the next semi-circular limiting groove 22 to the semi-circular limiting block 23. At this time, the spring 25 resets and pushes the semi-circular limiting block 23 into the current semi-circular limiting groove 22, limiting the semi-circular limiting groove 22 and keeping the cutting head 4 at the current rotation angle. Cutting at this time can then be cut at an angle.

[0043] Reference Figure 1 and Figure 8 The lower end of the movable wheel 3 is equipped with a track 7. One end of the track 7 is fixedly connected to a plate 10, and the other end of the track 7 is provided with a slot. The shape of the plate 10 and the slot are adapted to each other. Both the surface of the plate 10 and the slot are provided with threaded grooves 26.

[0044] When cutting steel, first place the rail 7 on the steel, then insert the insert plate 10 at the end of another rail 7 into the slot of the previous rail 7, so that the threaded groove 26 between the insert plate 10 and the slot is connected to each other, and rotate the bolt to connect the insert plate 10 and the slot. This makes it more convenient to splice the rail 7 and facilitates the movement of the machine body 1 on the rail 7.

[0045] Working principle: When the device needs to cut steel, the adjusting motor 6 is started to drive the bevel gear 20 to rotate, which in turn drives the bevel gear 21 to rotate, which in turn drives the bidirectional screw 13 to rotate. The bidirectional screw 13 drives the moving ring 9 to move in opposite directions. When the moving ring 9 moves, it is limited by the limiting plate 16 to make its movement more stable. This causes the moving ring 9 to drive the depth rod 8 to move, so that the position of the cutting head 4 is initially adjusted and the distance between the two cutting heads 4 is adjusted. Then, the hydraulic cylinder 12 is started to push the adjusting box 5 to move, so that the adjusting box 5 moves along the guide column 11, thereby driving the clamp frames 2 on both sides to move, further adjusting the distance between the cutting head 4 on both sides of the machine body 1 and the machine body 1. This makes the adjustment of the position of the cutting head 4 more flexible during the use of the device, which can be used for cutting plates of different sizes. The simultaneous use of two sets of cutting heads 4 greatly improves the cutting efficiency of the device and reduces the time required for cutting.

[0046] When steel needs to be cut, first rotate the mounting screw 17 to move the clamping plate 14 away from the moving ring 9 along the telescopic column 15. This causes the clamping bar 18 to move away from the clamping groove 19, so that it no longer limits the clamping groove 19. Then, move the depth rod 8 up and down to align the other clamping groove 19 with the clamping bar 18 inside the moving ring 9. Then, turn the mounting screw 17 to move the clamping plate 14 along the telescopic column 15 towards the moving ring 9 until both sides of the clamping groove 19 are limited by the clamping bar 18, fixing the depth rod 8 inside the moving ring 9. This also allows the cutting head 4 at its lower end to be adjusted in relation to the horizontal height of the steel when the depth rod 8 is adjusted. This allows the cutting head 4 to be adjusted according to the thickness of the steel plate during cutting, ensuring the cutting efficiency of the device. When the required steel is to be cut at an angle, the cutting head 4 is rotated, and the cutting head 4 abuts against the semi-circular limiting block 23, causing it to move along the sliding column 24 into the depth rod 8 and retracting the spring 25. This continues until the cutting head 4 is rotated so that the next semi-circular limiting groove 22 moves to the semi-circular limiting block 23. At this time, the spring 25 resets and pushes the semi-circular limiting block 23 into the current semi-circular limiting groove 22, limiting the semi-circular limiting groove 22 and keeping the cutting head 4 at the current rotation angle. Cutting at this time can then be done at an angle.

[0047] When cutting steel, first place the rail 7 on the steel, then insert the insert plate 10 at the end of another rail 7 into the slot of the previous rail 7, so that the threaded groove 26 between the insert plate 10 and the slot is connected to each other, and rotate the bolt to connect the insert plate 10 and the slot. This makes it more convenient to splice the rail 7 and facilitates the movement of the machine body 1 on the rail 7.

[0048] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
