Description

Technical Field

[0001] This utility model relates to the field of stone cutting devices, and in particular to a multi-angle adjustable stone cutting device. Background Technology

[0002] The core function of stone cutting equipment is to efficiently, accurately, and flexibly complete the cutting and processing of stone, while taking into account safety, environmental protection, and economy.

[0003] For example, a patent entitled "A Stone Cutting Machine Capable of Multi-Angle Cutting" (patent application number: 202222398518.8) discloses a stone cutting machine capable of multi-angle cutting. By controlling the operation of the first electric push rod, the first electric push rod pushes the clamping plate to move, so that the clamping plate clamps and fixes the stone. Then, the brake motor drives the rotating shaft to rotate, which in turn drives the cutting wheel to rotate. The tilt angle of the cutting wheel can be adjusted according to the cutting needs. However, in actual use, this device only relies on the first electric push rods on both sides to push one clamping plate for clamping, and the relative position of the clamping plate is fixed. Moreover, when dealing with large or irregularly shaped stones, it is impossible to move and adjust the appropriate clamping position according to the needs, which can easily lead to insufficient clamping force, causing the stone to loosen or break during the cutting process.

[0004] Therefore, it is necessary to propose a multi-angle adjustable stone cutting device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a multi-angle adjustable stone cutting device to solve the problems of traditional stone cutting machines in the prior art, such as the inability to adjust the clamping position and insufficient clamping force when cutting large or irregularly shaped stones.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-angle adjustable stone cutting device, including a worktable, wherein a moving positioning mechanism is provided on the side wall of the worktable;

[0007] The moving positioning mechanism includes a sliding frame, which is fixedly connected to the side wall of the worktable. A slide block is inserted into the inside of the sliding frame, and a rotating column is rotatably connected inside the slide block. A cam block is fixedly connected to the outside of the rotating column, and an insert block is slidably connected inside the slide block. A first through groove is formed on the opposite surface of the rotating column and the insert block, and the insert block is inserted into the first through groove. A first spring is fixedly connected between the insert block and the slide block. A partition is fixedly connected inside the slide block, and two abutment blocks are slidably connected inside the slide block. The opposite surfaces of the two abutment blocks abut against the outer surface of the cam block. A second spring is fixedly connected between the abutment block and the partition, and the side of the abutment block away from the second spring abuts against the inner wall of the sliding frame.

[0008] Preferably, the slide block is internally threaded with a trapezoidal screw, and an installation sleeve is rotatably connected to one end of the trapezoidal screw near the worktable. A replacement chuck is detachably fixedly installed on the inner side of the installation sleeve, and a slide rod is fixedly connected to the side of the installation sleeve away from the replacement chuck. The slide rod is slidably connected inside the slide block.

[0009] Preferably, a cutting groove plate is fixedly connected to the upper surface of the workbench.

[0010] Preferably, a first electric moving device is fixedly connected to the side wall of the worktable away from the moving positioning mechanism. The power output end of the first electric moving device is driven to a moving frame. A hydraulic cylinder is fixedly connected to the upper surface of the moving frame. A second electric moving device is fixedly connected to the output end of the hydraulic cylinder. A moving block is driven to the power output end of the second electric moving device. A servo motor is fixedly connected to the side surface of the moving block. A cutting device is fixedly connected to the output end of the servo motor.

[0011] Preferably, a spray pipe is fixedly connected to the outer surface of the cutting device.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. In this utility model, the moving positioning mechanism resets the abutment block under the action of the second spring force, and no longer presses against the inner wall of the slide frame. After pushing the slide block to slide along the slide frame to the position suitable for clamping the stone, the rotating column is rotated in the opposite direction to complete the positioning of the slide block, thereby adjusting the position of the clamping head so that it can be adjusted to a suitable clamping position according to the needs of different stones, thereby improving the clamping effect.

[0014] 2. Furthermore, the stone clamping assembly is constructed using a trapezoidal screw, sliding rod, mounting sleeve, and replaceable chuck. The replaceable chuck and mounting sleeve are detachably connected, allowing for the replacement of different types of chucks according to the shape of the stone, thus improving the clamping adaptability for irregular stones.

[0021] This utility model provides, for example Figures 1-5 The multi-angle adjustable stone cutting device shown is designed to solve the problems of traditional stone cutting machines, such as the inability to adjust the clamping position and insufficient clamping force when cutting large or irregularly shaped stones. It achieves stable clamping and precise multi-angle cutting of the stone. Its overall structure includes a worktable 1, a cutting groove plate 2, a moving positioning mechanism 3, a first electric moving device 4, a moving frame 5, a hydraulic cylinder 6, a second electric moving device 7, a cutting device 8, a moving block 9, a servo motor 10, and a spray pipe 11. All components work together to form a complete stone cutting system.

[0022] Workbench 1 is made of high-strength steel, providing a stable support foundation for the entire device and ensuring the overall stability of the device during the cutting process.

[0023] The cutting groove plate 2 is fixedly connected to the upper surface of the workbench 1. Its surface has a groove adapted to the cutting device 8. On the one hand, it provides clearance for the cutting operation of the cutting device 8 to avoid direct contact between the cutting device and the workbench and cause damage. On the other hand, it can collect the gravel and dust generated during the cutting process for easy cleaning later.

[0024] The moving positioning mechanism 3 is the core component for achieving stable clamping and position adjustment of the stone. It is fixed to the side wall of the workbench 1 and includes a sliding frame 31, a sliding seat 32, a trapezoidal screw 33, a sliding rod 34, an installation sleeve 35, a replacement chuck 36, a rotating column 37, a cam block 38, an insert block 39, a first spring 310, a partition plate 311, a second spring 312, and an abutment block 313. The sliding frame 31 and the sliding seat 32 are rectangular frame structures that provide sliding guidance for the sliding seat 32. The sliding seat 32 can slide along the length of the sliding frame 31, driving the subsequent clamping components to adjust their lateral position to adapt to the clamping requirements of stones of different sizes.

[0025] The rotating column 37, cam block 38, insert block 39, first spring 310, partition plate 311, second spring 312, and abutment block 313 together constitute the positioning structure of the slide block 32. When the rotating column 37 rotates, it drives the cam block 38 to rotate synchronously. The convex surface of the cam block 38 presses against the abutment blocks 313 on both sides, so that the abutment blocks 313 overcome the elastic force of the second spring 312 and abut tightly against the inner wall of the slide frame 31, realizing the initial positioning of the slide block 32 on the slide frame 31. The insert block 39 is inserted into the first through groove of the rotating column 37 under the elastic force of the first spring 310, restricting the rotation of the rotating column 37, further fixing the position of the slide block 32, and preventing the slide block from shifting during the cutting process.

[0026] The trapezoidal screw 33, slide bar 34, mounting sleeve 35, and replacement chuck 36 constitute a stone clamping assembly. When the trapezoidal screw 33 is rotated, under the guidance of the slide bar 34, the mounting sleeve 35 drives the replacement chuck 36 to move laterally along the slide block 32, thereby clamping or releasing the stone. The replacement chuck 36 is detachably connected to the mounting sleeve 35, and different types of chucks, such as flat chucks and curved chucks, can be replaced according to the shape of the stone to improve the clamping adaptability to irregular stones.

[0027] The first electric moving device 4 and the moving frame 5 are a linear module. The power output end of the first electric moving device 4 drives the moving frame 5 to move along the length of the worktable 1, thereby realizing the longitudinal position adjustment of the cutting device 8. The hydraulic cylinder 6 pushes the second electric moving device 7 to move up and down, thereby driving the cutting device 8 to adjust the cutting height to adapt to the cutting needs of different thicknesses of stone. The second electric moving device 7, the moving block 9, the servo motor 10, and the cutting device 8 are also linear modules. The second electric moving device 7 drives the moving block 9 to move laterally, thereby realizing the lateral cutting feed of the cutting device 8. The servo motor 10 can precisely control the rotation angle of the cutting device 8 to achieve multi-angle cutting. The specific structure and working principle of the first electric moving device 4, the second electric moving device 7, and the cutting device 8 are existing technologies, and therefore will not be described in detail in this utility model.

[0028] The spray pipe 11 is connected to an external water source. During the cutting process, coolant is sprayed onto the contact area between the cutting device 8 and the stone. This reduces the cutting temperature, preventing the cutting device from overheating and being damaged, and the stone from cracking due to high temperature. It also reduces cutting dust and improves the working environment.

[0029] Furthermore, when using it, select the appropriate replacement chuck 36 according to the shape of the stone to be cut and install it on the mounting sleeve 35; connect the spray pipe 11 to the external water source.

[0030] Manually pull the insert 39 outward to disengage it from the first through slot of the rotating column 37, thus releasing the restriction on the rotating column 37; rotate the rotating column 37 to disengage the cam block 38 from the abutment block 313, and the abutment block 313 returns to its original position under the elastic force of the second spring 312, no longer pressing against the inner wall of the slide frame 31; push the slide block 32 to slide along the slide frame 31 to the position suitable for clamping the stone, then rotate the rotating column 37 in the opposite direction, the cam block 38 presses the abutment block 313 against the slide frame 31, releasing the insert 39, and the insert is inserted into the first through slot under the action of the first spring 310, completing the positioning of the slide block 32.

[0031] Next, place the stone to be cut on the cutting groove plate 2 of the workbench 1, aligning the cutting part of the stone with the groove of the cutting groove plate; rotate the trapezoidal screw 33 to drive the changing chuck 36 to move towards the stone until the changing chuck is in close contact with the stone, firmly clamping the stone.

[0032] Furthermore, based on the cutting requirements, the control system sets the moving speed and stroke of the first electric moving device 4 to determine the longitudinal cutting range of the cutting device 8; controls the extension and retraction of the hydraulic cylinder 6 to adjust the height of the cutting device 8 so that the cutting wheel of the cutting device maintains a suitable initial distance from the stone surface; sets the feed speed of the second electric moving device 7, and adjusts the tilt angle of the cutting device 8 through the servo motor according to the required cutting angle, starts the cutting device 8, and turns on the spray pipe 11 for spray cooling; the control system starts the first electric moving device 4 and the second electric moving device 7, driving the cutting device 8 to cut the stone according to the set path and angle. After the cutting is completed, after the cutting device 8 stops rotating, the water source of the spray pipe 11 is turned off; the trapezoidal screw 33 is rotated in the opposite direction to loosen the replacement chuck 36 and remove the cut stone; and the gravel, dust and water on the cutting groove plate 2 and the workbench surface are cleaned.
