Description

Technical Field

[0001] This utility model is an arbitrary angle sawing machine, belonging to the field of sawing machine technology. Background Technology

[0002] Existing sawing equipment, represented by ordinary abrasive wheel cutters, suffers from multiple inherent defects in its overall structure and operation mode, which not only restricts work efficiency but also poses safety and environmental hazards. From a structural design perspective, this type of equipment uses a single power unit to drive the abrasive wheel to rotate, enabling only fixed-angle sawing actions. When dealing with workpieces requiring multi-angle processing, the workpiece's position must be repeatedly adjusted manually to complete the cut, making the operation cumbersome and difficult to guarantee accuracy. Especially in complex workpiece processing scenarios, the lack of compatibility and flexibility is particularly prominent, greatly limiting the equipment's applicability.

[0003] During operation, the high temperature generated by the high-speed rotation of the grinding wheel and friction with the material can cause continuous sparks to fly, posing a fire hazard to the surrounding environment and easily burning operators with the flying debris. Simultaneously, the grinding wheel releases a pungent metallic oxide odor and dust during grinding, and prolonged operation in an unprotected environment can harm workers' respiratory health, posing occupational health risks. More importantly, the grinding wheel itself is a brittle, bonded material; under high-speed rotation, uneven stress or the presence of micro-cracks can easily cause it to explode, with the flying fragments potentially causing direct worker injuries or even damaging surrounding equipment, resulting in extremely low safety. Furthermore, in single-power mode, the cutting efficiency of the grinding wheel is limited by its own rotational speed and wear rate. When dealing with high-strength, high-hardness materials, not only is the cutting speed slow, but frequent wheel replacements also increase downtime, leading to overall low operational efficiency and failing to meet the comprehensive demands of high efficiency, safety, and environmental protection in modern machining scenarios. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: an arbitrary angle sawing machine, comprising: The machine body has a crossbeam on the upper side, and columns are installed at both ends of the crossbeam. The lower ends of the columns are connected to the machine body by screws. Two sets of left and right positioning mechanisms are installed on the crossbeam, and angle positioning mechanisms are connected to the two sets of left and right positioning mechanisms through up and down feed mechanisms. A worktable is installed on the upper surface of the machine body, with one end of the worktable extending to the outside of the machine body. A movable seat is provided on the upper surface of the worktable, and a movable screw is connected to the movable seat through a ball nut pair. Both ends of the movable screw are connected to the worktable through bearing seats. A movable motor is installed on the upper surface of the worktable, and the output shaft of the movable motor is connected to one end of the movable screw.

[0006] Furthermore, the lower surface of the movable seat is slidably connected to two first linear guide rails via a slide block. The first linear guide rails are connected to the worktable by screws, and the first linear guide rails are arranged parallel to the movable lead screw.

[0007] Furthermore, two support legs are installed at the end of the worktable away from the machine body, and the support legs are arranged vertically.

[0008] Furthermore, a protective cover is installed on the upper surface of the machine body, a safety door is installed on one side of the protective cover, an inlet and outlet that cooperates with the movable seat is opened on the lower part of one side of the safety door, a mesh plate is installed on the side of the protective cover adjacent to the safety door, and an oil mist purifier is installed on the top of the protective cover.

[0009] Furthermore, the left and right positioning mechanism includes left and right positioning screws. Two horizontally arranged left and right positioning screws are provided on one side of the crossbeam. Both ends of the left and right positioning screws are connected to the crossbeam through rolling bearings. A left and right positioning motor is installed at the far end of the two left and right positioning screws. The left and right positioning motors are connected to the crossbeam through screws. Left and right positioning seats are connected to the left and right positioning screws through ball nut pairs. The left and right positioning seats are slidably connected to two second linear guides through slide blocks. The second linear guides are connected to the crossbeam through screws. The second linear guides are parallel to the left and right positioning screws.

[0010] Furthermore, the up-and-down feed mechanism includes an up-and-down feed motor. The up-and-down feed motor is mounted on the opposite side of the two left and right positioning seats. A power pulley is mounted on the output shaft of the up-and-down feed motor. The power pulley is connected to a driven pulley via a transmission belt. An up-and-down feed screw is mounted on the lower surface of the driven pulley. Both ends of the up-and-down feed screw are rotatably connected to the left and right positioning seats via rolling bearings. The up-and-down feed screw is connected to the angle positioning mechanism via a ball nut pair.

[0011] Furthermore, the angle positioning mechanism includes an angle positioning seat. The upper and lower feed screws are connected to the angle positioning seat via ball nut pairs. The angle positioning seat is slidably connected to two third linear guides via slide blocks. The third linear guides are connected to the left and right positioning seats via screws. The third linear guides are arranged parallel to the upper and lower feed screws. An angle positioning motor is mounted on the horizontal part of the angle positioning seat. A bushing is mounted on the lower surface of the horizontal part of the angle positioning seat. A sawing motor is provided under the bushing. An alloy saw blade is mounted on the output shaft of the sawing motor. The output shaft of the angle positioning motor is connected to the sawing motor via a connecting shaft.

[0012] Furthermore, the upper surface of the machine body is recessed downward to form two material discharge bins symmetrically arranged about the worktable. A chip conveyor is provided at the bottom of the material discharge bin, and a mobile trolley is provided at the discharge port of the chip conveyor.

[0013] The beneficial effects of this utility model are: The angle positioning motor directly drives the sawing motor to rotate via a connecting shaft, enabling the inlaid carbide saw blade to precisely adjust the sawing angle without the need for repeated manual workpiece movement. Combined with left and right positioning screws driving the lateral movement of the inlaid carbide saw blade and up and down feed screws controlling the blade, it allows for flexible adjustment of the inlaid carbide saw blade in three dimensions: horizontal, vertical, and angle. This adapts to sawing needs ranging from right angles and bevels to any complex angle. Whether it's simple straight-line cutting or multi-angle processing of complex workpieces, frequent adjustments to the equipment or workpiece position are unnecessary, significantly improving operational flexibility and compatibility, and broadening the equipment's applicable scenarios. Through the angle positioning mechanism and multi-dimensional drive design, it solves the problem of traditional equipment only being able to operate at a fixed angle.

[0014] The protective cover effectively collects dust and oil mist generated during sawing, preventing them from spreading into the workshop air. The oil mist purifier installed on the top of the protective cover can quickly absorb and purify the oil mist, metal dust, and odors generated during sawing, reducing harm to the respiratory system of operators and lowering occupational health risks. At the same time, the perforated plate ensures air circulation inside the protective cover and further filters some dust, avoiding the pollution scene of sparks flying and dust spreading during traditional abrasive wheel cutting, making the working environment more in line with environmental protection and occupational health requirements.

[0015] The use of inlaid carbide saw blades instead of traditional bonded abrasive wheels has made the inlaid carbide saw blades a rigid, integral structure that is less prone to cracking due to uneven stress during high-speed rotation. This reduces sparks and exhaust fumes, and eliminates the risk of worker injuries and equipment damage caused by flying fragments from broken abrasive wheels. Attached Figure Description

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Please see Figure 1 , Figure 2 and Figure 4This utility model provides a technical solution: an arbitrary angle sawing machine, including a machine body 1, a worktable 2 installed on the upper surface of the machine body 1, one end of the worktable 2 extending to the outside of the machine body 1, a movable seat 23 provided on the upper side of the worktable 2, the movable seat 23 being connected to a movable screw 22 via a ball nut pair, both ends of the movable screw 22 being connected to the worktable 2 via bearing seats, a movable motor 24 installed on the upper surface of the worktable 2, the output shaft of the movable motor 24 being connected to one end of the movable screw 22; two first linear guide rails 25 are slidably connected to the lower surface of the movable seat 23 via a sliding block, the first linear guide rails 25 being connected to the worktable 2 via screws, the first linear guide rails 25 being arranged parallel to the movable screw 22; two support legs 21 are installed on the end of the worktable 2 away from the machine body 1, the support legs 21 being arranged vertically. The moving motor 24 drives the moving screw 22 to rotate, which can drive the moving seat 23 to move smoothly along the first linear guide rail 25, realizing automatic workpiece feeding without manual pushing of the workpiece, reducing the intensity and time of manual operation; the support leg 21 can support the part of the worktable 2 that extends to the outside of the machine body 1, avoiding deformation of the worktable 2 due to long-term stress.

[0019] See Figures 1-4 The machine body 1 has a crossbeam 5 on its upper side, with columns 51 installed at both ends. The lower ends of the columns 51 are connected to the machine body 1 by screws. Two horizontally arranged left and right positioning screws 53 are located on one side of the crossbeam 5. Both ends of the left and right positioning screws 53 are connected to the crossbeam 5 via rolling bearings. Left and right positioning motors 54 are installed at the ends of the two left and right positioning screws 53 that are furthest apart. The left and right positioning motors 54 are connected to the crossbeam 5 by screws. Left and right positioning seats 55 are connected to the left and right positioning screws 53 via ball bearing pairs. The left and right positioning seats 55 are slidably connected to two second linear guides 52 via sliding blocks. The second linear guides 52 are connected to the crossbeam 5 by screws and are parallel to the left and right positioning screws 53. The left and right positioning motors 54 drive the left and right positioning screws 53 to rotate, which in turn moves the left and right positioning seats 55 laterally along the second linear guides 52, thereby adjusting the distance between the two left and right positioning seats 55 to adapt to the sawing requirements of workpieces of different widths.

[0020] See Figures 1-4Each of the two left and right positioning seats 55 has a vertical feed motor 7 mounted on its back. A power pulley 72 is mounted on the output shaft of the vertical feed motor 7. The power pulley 72 is connected to a driven pulley 74 via a transmission belt 73. A vertical feed screw 71 is mounted on the lower surface of the driven pulley 74. Both ends of the vertical feed screw 71 are rotatably connected to the left and right positioning seats 55 via rolling bearings. The vertical feed screw 71 is connected to an angle positioning seat 6 via a ball nut pair. The angle positioning seat 6 is slidably connected to two third linear guides 65 via a slide block. The third linear guide rail 65 is arranged parallel to the upper and lower feed screws 71 and is connected to the left and right positioning seats 55 by screws. An angle positioning motor 61 is installed on the horizontal part of the angle positioning seat 6. A bushing 64 is installed on the lower surface of the horizontal part of the angle positioning seat 6. A sawing motor 63 is provided on the lower side of the bushing 64. An alloy saw blade 62 is installed on the output shaft of the sawing motor 63. The output shaft of the angle positioning motor 61 is connected to the sawing motor 63 through a connecting shaft. A shield is fitted on the angle positioning motor 61. The shield is connected to the angle positioning seat 6 by screws.

[0021] The angle positioning motor 61 directly drives the sawing motor 63 to rotate via a connecting shaft, enabling the inlaid carbide saw blade 62 to precisely adjust the sawing angle without the need for repeated manual workpiece movement. Combined with the left and right positioning screws 53 driving the lateral movement of the inlaid carbide saw blade 62 and the up and down feed screws 71 controlling its vertical movement, the inlaid carbide saw blade 62 can be flexibly adjusted in three dimensions: horizontal, vertical, and angle. This adapts to sawing needs ranging from right angles and oblique angles to any complex angle. Whether it's simple straight-line cutting or multi-angle processing of complex workpieces, frequent adjustments to the equipment or workpiece position are unnecessary, significantly improving operational flexibility and compatibility, and broadening the equipment's applicable scenarios. The angle positioning mechanism and multi-dimensional drive design solve the problem of traditional equipment only being able to operate at a fixed angle. Replacing the traditional bonded abrasive wheel with the inlaid carbide saw blade 62, the inlaid carbide saw blade 62 has an integral rigid structure, making it less prone to breakage due to uneven stress during high-speed rotation, reducing sparks and exhaust gas generation, and eliminating the risk of worker injuries and equipment damage caused by flying fragments of the abrasive wheel.

[0022] See Figure 1A protective cover 12 is installed on the upper surface of the machine body 1. A safety door 11 is installed on one side of the protective cover 12. An inlet and outlet that cooperates with the movable base 23 is opened on the lower part of one side of the safety door 11. A perforated plate 13 is installed on the side of the protective cover 12 adjacent to the safety door 11. An oil mist purifier 3 is installed on the top of the protective cover 12. The protective cover 12 can effectively collect the dust and oil mist generated during the sawing process and prevent them from spreading into the workshop air. The oil mist purifier 3 installed on the top of the protective cover 12 can quickly absorb and purify the oil mist, metal dust and odor generated during sawing, reduce the harm to the respiratory system of operators and reduce occupational health risks. At the same time, the setting of the perforated plate 13 not only ensures the air circulation inside the protective cover 12, but also further filters some dust, avoiding the pollution scene of sparks flying and dust spreading during traditional abrasive wheel cutting, making the working environment more in line with environmental protection and occupational health requirements.

[0023] See Figure 1 The upper surface of the machine body 1 is recessed downwards to form two symmetrically arranged material discharge bins 14 about the workbench 2. A chip conveyor 4 is provided at the bottom of the material discharge bins 14, and a mobile trolley 41 is provided at the discharge port of the chip conveyor 4. The material discharge bins 14 on the upper surface of the machine body 1 are symmetrically arranged around the workbench 2. The sawing chips can fall directly into the material discharge bins 14, avoiding chips from scattering on the workbench 2 or the ground. The chip conveyor 4 at the bottom of the material discharge bins 14 can automatically transport the chips to the mobile trolley 41, eliminating the need for manual cleaning and collection, reducing the cleaning labor intensity of the operators. When the mobile trolley 41 is full, it can be directly transferred for disposal, avoiding equipment jamming or environmental pollution caused by chip accumulation, ensuring continuous and stable operation of the equipment, and reducing workshop cleaning costs.
