Technical Field
[0001] This utility model relates to the field of power tool technology, and in particular to an adjustable marble cutter. Background Technology
[0002] Marble cutting machines are core power tools used in cutting hard and brittle materials such as stone, ceramic tiles, and concrete. They achieve efficient material cutting through a high-speed rotating saw blade. A typical marble cutting machine consists of a drive motor, a cutting saw blade, a protective cover, and an operating handle. The depth-of-cut adjustment function directly affects processing accuracy and ease of operation. Traditional marble cutting machines mostly control the cutting depth by adjusting the exposed height of the saw blade. However, existing adjustment mechanisms have significant shortcomings in ergonomic design and functional expandability, especially when cutting equidistant slabs, requiring additional auxiliary devices and complicating the operation process.
[0003] Current marble cutters generally employ a "single-axis rotation - arc plate lifting" depth adjustment scheme. One end of the saw blade base is connected to the machine body via a fixed rotating shaft, while the other end moves along a preset arc-shaped guide rail and is locked in place by screws to change the contact depth between the saw blade and the material. However, this structure requires an external limiting component when cutting equidistant plates. This limiting component is usually fixed to the bottom of the marble cutter via a slot or bolt and slides against the edge of the entire plate to maintain the cutting spacing. Because the limiting component and the machine body are designed separately, their installation accuracy is limited by processing errors and operator experience, which can easily lead to deviations in the cutting trajectory.
[0004] Although existing methods can adjust the cutting depth, they have systemic flaws: the rotation of the saw blade base during depth adjustment forces the entire machine body to deflect, causing the operating handle angle to shift unexpectedly. Users need to frequently adapt to the grip posture, which can easily lead to fatigue and operational instability. At the same time, the adjustment method that relies on manually tightening and loosening screws to fix the arc plate is inefficient and has poor locking stability, and cutting vibration can easily cause depth deviation. In addition, the connection between the external split limiting component and the machine body lacks a precise positioning mechanism, and manual calibration is required during installation. During the cutting process, uneven sliding resistance or loose parts can easily lead to errors in the spacing of the plates, which seriously affects the consistency and efficiency of batch processing.

[0007] A further preferred embodiment of this utility model is as follows: the limiting component includes an adjusting groove, a fixed plate, a slider, a stop rod, a second elastic element, a sleeve, an adjusting rod, a slot, and a bolt. The fixed plate is connected to the front and rear ends of the contact plate through its left and right ends. Both the fixed plate and the contact plate have adjusting grooves. The slider is sleeved in the middle of the fixed plate and is slidably connected to the fixed plate and the contact plate respectively. A sleeve is connected to the slider, and an adjusting rod is slidably connected inside the sleeve. A stop rod is rotatably connected to the bottom of the adjusting rod and is slidably connected to the adjusting groove. The stop rod and the sleeve are in a limiting fit. A second elastic element is sleeved on the adjusting rod. One end of the second elastic element is connected to the sleeve, and the other end is connected to the adjusting rod. Several equally spaced slots are opened on the fixed plate, and the bolt passes through the slider and is in a limiting fit with the slots.
[0008] A further preferred embodiment of this utility model is: it also includes an extrusion plate, and the top of the adjusting rod is connected to the extrusion plate.
[0009] A further preferred embodiment of this utility model is: it also includes a guide ring, and a guide ring is provided in the slot.
[0010] A further preferred embodiment of this utility model is: it also includes identification cards, and a number of identification cards are connected to the fixing plate. The identification cards are used to record different lengths.
[0011] A further preferred embodiment of this utility model is: it also includes shock-absorbing pads, and shock-absorbing pads are connected to the top of the base plate, the bottom of the mounting plate, and the bottom of the movable block.

[0014] Compared with the prior art, the advantages of this utility model are: the adjusting screw drives the moving block to move up and down along the U-shaped part, driving the marble cutter to rise and fall. At the same time, the mounting plate slides along the guide rod and compresses the first elastic element, ensuring that the marble cutter rises and falls synchronously on both sides. Thus, there is no need to adjust the grip posture when adjusting the cutting depth, improving the operating comfort and cutting stability. The slider position is locked by the bolt rod, and the adjusting rod presses down the stop bar to below the contact plate. The vertical position is locked by the transverse groove of the sleeve, ensuring that the stop bar is in close contact with the plate, quickly positioning the cutting width, and ensuring the equidistant accuracy and efficiency of batch cutting.

[0022] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.
[0023] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.
[0024] This embodiment mainly describes the structure of the marble machine, as follows:
[0025] An adjustable marble machine, such as Figures 1-5 As shown, the assembly includes a marble cutter 1, a contact plate 2, a base plate 3, a mounting plate 4, a guide rod 5, a first elastic element 6, a moving block 7, an adjusting screw 8, a U-shaped component 9, and a limiting assembly. The contact plate 2 is mounted on the bottom of the marble cutter 1, and several base plates 3 are connected to the contact plate 2. Several mounting plates 4 are connected to one side of the marble cutter 1, and several U-shaped components 9 are connected to the other side. The U-shaped components 9 and mounting plates 4 are alternately arranged to ensure that the marble cutter 1 remains parallel to the contact plate 2 after adjustment. A guide rod 5 is slidably connected inside the mounting plate 4, and the bottom of the guide rod 5 is fixedly connected to the base plate 3. The diameter of the hole in the mounting plate 4 is aligned with the guide rod 5. The diameters of rods 5 are equal. Mounting plate 4 and guide rod 5 are fitted together to ensure that mounting plate 4 can only move up and down. A first elastic element 6 is sleeved on guide rod 5. One end of the first elastic element 6 is connected to guide rod 5 and the other end is connected to mounting plate 4. A moving block 7 is slidably connected to the open end of U-shaped part 9. An adjusting screw 8 is internally threaded to the moving block 7. The bottom of adjusting screw 8 is slidably connected to base plate 3. Adjusting screw 8 has a hexagonal head and a hexagonal groove is opened in the hexagonal head. The hexagonal head structure of adjusting screw 8 is adapted to narrow spaces or high torque requirements. A limiting component with a limited cutting width is set on contact plate 2.
[0026] like Figure 1 , Figure 4 and Figure 5 As shown, the limiting assembly includes an adjusting groove 10, a fixed plate 11, a slider 12, a stop bar 13, a second elastic element 14, a sleeve 15, an adjusting rod 16, a slot 17, and a bolt 18. The fixed plate 11 is connected to the front and rear ends of the contact plate 2 via its left and right ends. Both the fixed plate 11 and the contact plate 2 have adjusting grooves 10. The slider 12 is sleeved in the middle of the fixed plate 11 and is slidably connected to both the fixed plate 11 and the contact plate 2. A sleeve 15 is connected to the slider 12, and an adjusting rod 16 is slidably connected inside the sleeve 15. The bottom of the adjusting rod 16 is rotatably connected to the stop bar 13. The stop rod 13 is slidably connected in the adjusting groove 10. The stop rod 13 is limited to the sleeve 15. The sleeve 15 is provided with a through groove. The top and bottom of a longitudinal groove are connected by a transverse groove. The top of the stop rod 13 is connected to a control rod. The control rod is slidably connected in the sleeve 15 and is limited to the sleeve 15. The adjusting rod 16 is fitted with a second elastic element 14. One end of the second elastic element 14 is connected to the sleeve 15 and the other end is connected to the adjusting rod 16. The fixing plate 11 has several equidistant slots 17. The bolt 18 passes through the slider 12 and is limited to the slots 17.
[0027] like Figure 5 As shown, it also includes an extrusion plate 19, and the top of the adjusting rod 16 is connected to the extrusion plate 19.
[0028] like Figure 4 As shown, it also includes a guide ring 20. The guide ring 20 is provided in the slot 17. When the bolt 18 is inserted into the slot 17, the guide ring 20 guides the bolt 18 to be axially aligned through the inner wall tapered structure, ensuring that the end of the bolt 18 is in uniform contact with the inner wall of the slot 17, and eliminating the lateral displacement of the slider 12 caused by manual alignment deviation.
[0029] like Figure 4 As shown, it also includes identification cards 21. Several identification cards 21 are connected to the fixing plate 11. The identification cards 21 are used to record different lengths. The operator can quickly determine the cutting width by comparing the current position of the slider 12 with the scale of the identification card 21 without the need for external measuring tools.
[0030] like Figure 2 As shown, it also includes shock-absorbing pads 22. The top of the base plate 3, the bottom of the mounting plate 4, and the bottom of the moving block 7 are all connected to shock-absorbing pads 22. The shock-absorbing pads 22 are made of rubber and are used to absorb the impact force of the marble machine 1 falling and extend the service life of the components.
[0031] like Figure 2 As shown, it also includes an adsorption component 23. The adsorption component 23 is connected to the opening of the U-shaped component 9. The adsorption component 23 is a magnet, and the moving block 7 is a magnetic metal. Through the magnetic attraction between the adsorption component 23 and the moving block 7, the height of the marble machine 1 can be reset with one key, avoiding manual calibration.
[0032] When changing the cutting depth of the marble cutter 1, the adjusting screw 8 is turned. Because the adjusting screw 8 has a hexagonal groove, it can be rotated using an adjustable wrench or a hex wrench. During rotation, the moving block 7 moves up and down along the adjusting screw 8. The moving block 7 is rigidly connected to one side of the marble cutter 1 via a U-shaped component 9, driving the entire machine to rise and fall vertically. Simultaneously, the mounting plate 4 on the other side of the marble cutter 1 slides along the guide rod 5. The transition fit between its inner hole and the guide rod 5 restricts the mounting plate 4 to only translate, preventing rotation, ensuring synchronous lifting on both sides. During lifting, the first elastic component 6 is compressed and stores energy by the mounting plate 4, and its rebound force balances the gravity of the marble cutter 1. The alternating left and right distribution of the U-shaped component 9 and the mounting plate 4 forms symmetrical support, providing strong... The parallelism between the marble cutter 1 and the contact plate 2 is maintained to perform the cutting operation, and the holding posture of the marble cutter 1 remains unchanged. After the cutting operation is completed, the moving block 7 is pulled outward, causing it to cause the adjusting screw 8 to disengage from the base plate 3. At the same time, the moving block 7 slides out from the opening of the U-shaped part 9, and the marble cutter 1 falls freely under the action of gravity. The first elastic element 6 releases its stored energy to push the mounting plate 4 down, ensuring that the mounting plate 4 is in contact with the base plate 3. The shock-absorbing pad 22 on the top of the base plate 3 absorbs the impact energy of the marble cutter 1 falling through deformation, reducing collision damage. The adjusting screw 8 is rotated again to align the moving block 7 with the opening of the U-shaped part 9. After the moving block 7 is pushed in, the magnetic adsorption element 23 inside the U-shaped part 9 adsorbs and fixes the moving block 7, realizing the rapid and accurate reset of the height of the marble cutter 1.
[0033] When cutting equidistant materials and adjusting the cutting width, the operator determines the cutting width according to the scale marked on the identification card 21, pulls out the bolt 18 to release the lock between the slider 12 and the slot 17, slides the slider 12 laterally along the fixing plate 11 to the target marked position, aligns the bolt 18 with the slot 17 and inserts it. Under the guidance of the guide ring 20, the bolt 18 is precisely embedded in the slot 17, achieving rigid fixation between the slider 12 and the fixing plate 11. Then, the operator holds the control rod and rotates it 90° counterclockwise to disengage the control rod from the transverse limiting groove at the top of the sleeve 15. At this time, the operator presses down on the compression plate 19, causing the adjusting rod 16 to move down along the inner wall of the sleeve 15, compressing the second elastic element 14. At the same time, the stop rod 13 moves with the adjusting rod. 16 descends synchronously and extends through the adjustment groove 10 to below the contact plate 2; when the stop rod 13 fully touches the bottom, the control rod is rotated 90° clockwise to lock into the transverse limiting groove at the bottom of the sleeve 15, forming a vertical lock on the stop rod 13. The downward-moving stop rod 13 passes through the adjustment groove 10 of the fixed plate 11 and the contact plate 2 in sequence. During the cutting process, the stop rod 13 slides close to the side of the plate. Because the stop rod 13 and the adjustment rod 16 are connected to each other by rotation, the stop rod 13 can adaptively deflect to reduce frictional resistance when the marble machine 1 moves; after the cutting is completed, the control rod is rotated in the opposite direction to release the limit, and the second elastic element 14 rebounds to push the adjustment rod 16 and the stop rod 13 to rise and reset, and the stop rod 13 is completely retracted into the adjustment groove 10.
