Abstract
Description
Technical Field
[0001] This utility model relates to the field of stone edge grinding machine technology, and in particular to a stone edge grinding machine with variable angle. Background Technology
[0002] During the processing of stone slabs, they need to be cut and ground to achieve the dimensions required by the customer, with a dimensional accuracy generally within ±0.1mm. After cutting, the stone will have cutting marks on the sides, which not only affects the appearance but also easily causes micro-cracks during use, affecting subsequent use. Therefore, after cutting, the stone must be chamfered; otherwise, chipping is very likely to occur during subsequent operations.
[0003] In existing stone edge grinding machines, dust easily remains on the outside of the grinding wheel during grinding. This residual dust interferes with the normal grinding process of the stone and reduces processing efficiency.
[0004] Therefore, it is necessary to propose a stone edge grinding machine with a variable angle to solve the above problems. Utility Model Content

[0021] This utility model provides, for example Figures 1-5The variable angle stone edging machine shown includes an operating table 1, on which a notch 2 is formed. A square plate 3 is placed above the notch 2. A rotating shaft 5 is rotatably connected to the square plate 3. A motor 16 is fixedly connected to the square plate 3. The motor 16 is connected to the factory's power supply. The motor 16 can be, but is not limited to, a Y-series three-phase asynchronous motor, model Y80M1-2. The rotating shaft 5 is fixedly connected to the drive shaft of the motor 16. A grinding column 6 is installed on the rotating shaft 5. The grinding column 6 can be made of, but is not limited to, diamond material and is suitable for fine grinding of stone.
[0022] In actual use, motor 16 drives shaft 5 to rotate, and shaft 5 drives grinding column 6 to rotate.
[0023] To fix the grinding column 6, a fixing assembly for fixing the grinding column 6 is provided on the rotating shaft 5. The fixing assembly includes a limiting ring 7 and a nut 8. The limiting ring 7 is fixedly connected to the rotating shaft 5, and the outer diameter of the limiting ring 7 is larger than the outer diameter of the rotating shaft 5. The nut 8 is threadedly connected to the rotating shaft 5, and the grinding column 6 is located between the limiting ring 7 and the nut 8.
[0024] A support plate 13 is fixedly connected to the side of the square plate 3 facing away from the rotating shaft 5. A round rod 14 is rotatably connected to the support plate 13 and is fixedly connected to the inner wall of the notch 2. An electric push rod 15 is provided on the outside of the operating table 1. The fixed end of the electric push rod 15 is hinged to the outer wall of the operating table 1, and the telescopic end of the electric push rod 15 is hinged to the end of the support plate 13 away from the square plate 3. The tilt angle of the rotating shaft 5 is adjusted by using the electric push rod 15.
[0025] When using, refer to Figure 3 As shown, when the telescopic end of the control electric push rod 15 extends, the end of the grinding column 6 away from the support plate 13 tilts downward, while when the telescopic end of the control electric push rod 15 retracts, the end of the grinding column 6 away from the support plate 13 tilts upward.
[0026] In actual operation, the extension length of the electric push rod 15 is adjusted according to the specific angle required for chamfering the stone, so that the angle between the grinding column 6 and the stone reaches the required value, meeting the needs of different chamfering angles, improving the versatility and applicability of the equipment, and adapting to various stone processing scenarios.
[0027] Specifically, rotate nut 8 to separate it from shaft 5, put grinding post 6 onto shaft 5, and rotate nut 8 again to lock grinding post 6 with nut 8 and limit ring 7, thus fixing grinding post 6. Grinding post 6 can be replaced periodically.
[0028] Furthermore, during the edge grinding operation, the stone is placed on the workbench 1, with the top of the side of the stone in contact with the grinding column 6. The motor 16 drives the rotating shaft 5 to rotate, and the rotating shaft 5 drives the grinding column 6 to rotate, grinding the side of the stone and pushing the stone to move during the process.
[0029] In actual production, fixed components (including clamps, etc.) and pushing components (including slides, lead screws, etc.) can be set on the operating table 1 to drive the stone to move. Fixed components and pushing components are common existing technologies and will not be described in detail here.
[0030] A fan 9 is mounted on the rotating shaft 5, located between the motor 16 and the grinding column 6. An outer cylinder 10 is provided outside the fan 9, and a guide shroud 12 is fixedly connected to the rotating shaft 5. An air delivery channel is formed between the inner wall of the outer cylinder 10 and the outer wall of the guide shroud 12, leading to the outer circumference of the grinding column 6 (see reference). Figure 4 Furthermore, the air supply channel gradually narrows towards the grinding column 6.
[0031] A connecting rod 11 is fixedly connected to the inner wall of the outer cylinder 10. The connecting rod 11 is fixedly connected to the rotating shaft 5. The connecting rod 11 is set to fix the outer cylinder 10.
[0032] When in use, as the motor 16 drives the grinding column 6 to rotate and grind the side of the stone, the fan 9 also rotates. The airflow generated is blown to the outer surface of the grinding column 6 through the air supply channel, which blows away the dust generated during the grinding process in time, effectively reducing the dust residue on the outside of the grinding wheel, avoiding dust interference with the normal grinding process of the grinding wheel on the stone, and improving processing efficiency and quality.
[0033] Meanwhile, the air supply channel gradually narrows towards the grinding column 6, which allows the airflow to gradually increase in speed after entering the channel, making the wind stronger and thus more effectively blowing the dust generated during the grinding process away from the outer circumference of the grinding column 6.
[0034] Multiple through slots 4 are provided on the square plate 3, making the square plate 3 hollow. When the fan 9 rotates, it can draw heat from the motor 16 to help dissipate heat from the motor 16.
[0035] This utility model, through the arrangement of a rotating shaft 5, a fan 9, an outer cylinder 10, and a guide shroud 12, allows airflow to be blown towards the outer circumference of the grinding column 6 through an air supply channel, promptly blowing away the dust generated during the grinding process. This effectively reduces dust residue on the outside of the grinding wheel, preventing dust from interfering with the normal grinding process of the stone. Furthermore, the air supply channel gradually narrows towards the grinding column 6, allowing the airflow speed to gradually increase after entering the channel. At the same time, it assists in the heat dissipation of the motor 16, improving the efficiency of the stone edge grinding machine.
[0036] In addition, the air central treatment duct outlet of the factory can be placed close to the operating table 1 so that the blown dust can be treated. Dust central treatment is a common existing technology and will not be described in detail here.
