[0002] In modern mechanical manufacturing, there are many methods for processing mechanical parts: in addition to cutting, there are casting, forging, welding, stamping, extrusion, etc. Before being processed into finished products, materials generally need to undergo final processing on machine tools using cutting methods. As modern manufacturing industries develop towards high efficiency, high precision, and economy, sawing, as the starting point of precision cutting, has become an important component in the parts processing process. Sawing can save materials, reduce secondary processing, and improve production efficiency; therefore, sawing machines are widely used in various sectors of the national economy, including steel, machinery, automobiles, shipbuilding, petroleum, mining, and aerospace.

[0003] With rising production and labor costs, intelligent manufacturing has become an urgent need for enterprises, leading to the widespread application of automated machining production lines in automotive parts manufacturing. Die-cast parts are a crucial component of automotive parts, containing sprues and runners, which are production accessories that need to be removed. However, due to the complex shapes of these parts, multi-faceted and multi-angle removal is required. Currently, manual sawing is mostly used to remove large portions of waste material, with the remaining portion milled using a machining center. The problems with manual sawing are twofold: firstly, it is unsafe; secondly, the removal cycle is long, impacting production efficiency. Utility Model Content

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0035] like Figure 1 and Figure 2 As shown, a sawing machine according to an embodiment of the present invention is used to cut the waste portion 10 on a workpiece 1. It includes a frame 100, a worktable 200, a tilting assembly 300, a rotating assembly 400, a moving assembly 500, and a cutting assembly 600. The worktable 200 is located on one side of the frame 100, and multiple clamping assemblies 210 are provided on the worktable 200 to fix the workpiece 1 located on the worktable 200. The tilting assembly 300 is fixed to the bottom of the worktable 200 and is used to drive the worktable. The worktable 200 rotates circumferentially around the X-axis. The rotating component 400 is fixed on the tilting component 300 and drives the worktable 200 to rotate around the Z-axis. The moving component 500 is mounted on the frame 100 and fixedly connected to the tilting component 300, and drives the worktable 200 to move along the Y-axis. The cutting component 600 includes a saw blade 680, the surface 681 of which is parallel to the plane containing the X and Z axes, and the saw blade 680 can move within the plane containing the X and Z axes to cut the workpiece 1 located on the worktable 200. During operation, firstly, the moving component 500 drives the worktable 200 to the first position, which is the loading position. At this time, the robotic arm places the workpiece 1 on the worktable 200 and fixes it with the clamping component 210. Then, the moving component 500 drives the worktable 200 to the second position for cutting. During cutting, the tilting component 300, the rotating component 400, and the cutting component 600 cooperate to cut the waste section 10. During the specific cutting process, the flipping component 300 drives the worktable 200 to rotate around the X-axis to change the tilt angle of the workpiece 1, while the rotating component 400 drives the worktable to rotate around the Z-axis to adjust the circumferential orientation of the workpiece 1, aligning the scrap portion 10 with the saw blade 680. Finally, the cutting component 600 drives the saw blade to move within the planes containing the X and Z axes, completing the cutting of the scrap portion 10. After the scrap portion 10 on the workpiece 1 is removed, the moving component 500 drives the worktable 200 back to the first position. At this time, the clamping component 210 releases the workpiece 1, and the robotic arm removes the workpiece 1, thus completing the cutting of one workpiece. Through the coordinated movement of multiple components, the workpiece's posture in any spatial position and the saw blade position can be adjusted. The entire process requires no manual intervention, significantly improving cutting efficiency. At the same time, the relative position of the saw blade and the workpiece can be precisely controlled, avoiding errors from manual operation and ensuring cutting accuracy. This is especially suitable for batch processing scenarios involving irregularly shaped workpieces or complex scrap portions.

[0036] The frame 100 is also equipped with a scrap outlet 140, which is located directly below the saw blade 680. The scrap part 10 falls from the scrap outlet 140 into the scrap box under the action of gravity. It is worth noting that the second position is located near the scrap outlet 140, and after the workpiece 1 has completed its posture adjustment in space, the workpiece 1 is located directly above the scrap outlet 140.

[0037] like Figure 3 As shown, the clamping assembly 210 includes a mounting base 211, a linkage arm 212, a clamping block 213, and a cylinder 214. One end of the linkage arm 212 is hinged to the mounting base 211 via a first rotating shaft 215, and the other end is hinged to the clamping block 213 via a second rotating shaft 216. The end of the clamping block 213 is hinged to the piston rod 2140 of the cylinder 214 via a third rotating shaft 217. A clamping part 2130 for pressing the workpiece 1 is provided on the end of the clamping block 213 away from the third rotating shaft 217. During operation, the piston rod 2140 of cylinder 214 extends and retracts, causing the clamping block 213 to rotate around the third rotating shaft 217. Simultaneously, the linkage arm 212 rotates in cooperation with the first rotating shaft 215 and the second rotating shaft 216, enabling the clamping part 2130 to clamp or release the workpiece 1. Specifically, when the piston rod 2140 extends, the clamping part 2130 moves downward and presses firmly against the workpiece 1; when the piston rod retracts, the clamping part 2130 lifts upward, releasing the constraint on the workpiece 1. The clamping force of the clamping part 2130 can be precisely controlled by the air pressure of cylinder 214, which can prevent the workpiece 1 from loosening and shifting during cutting, and also prevent excessive pressure from causing deformation or surface damage to the workpiece 1. At the same time, the automated clamping action reduces manual operation steps and improves clamping efficiency.

[0038] like Figure 2 As shown, the worktable 200 is equipped with multiple positioning posts 220, which are located at the bottom edge of the workpiece 1. The workpiece 1 has multiple positioning holes that correspond to and engage with the positioning posts 220. During operation, the robotic arm aligns the positioning holes on the bottom of the workpiece 1 with the positioning posts 220 on the worktable 200, inserting the positioning posts 220 into the positioning holes, thus quickly completing the initial placement and positioning of the workpiece. The multiple positioning posts 220 provide multi-point positioning from the bottom edge of the workpiece 1, precisely limiting the workpiece's position on the worktable 200 and ensuring that the position of the workpiece 1 remains consistent with each clamping, preparing for subsequent cutting by the cutting assembly 600. Simultaneously, the hard-fit structure between the positioning posts 220 and the positioning holes is stable and reliable, unaffected by external vibrations, effectively preventing dimensional deviations caused by slight workpiece movement during the cutting process.

[0039] like Figure 2As shown, the worktable 200 is equipped with multiple limiting plates 230, which abut against the inner wall and / or outer wall of the workpiece 1 respectively. The limiting plates 230 can further counteract the lateral force generated by the saw blade 680 on the workpiece 1 during the cutting process, preventing the workpiece 1 from shifting or shaking horizontally due to force, and forming a double positioning with the positioning post 220; at the same time, the limiting plates 230 are fixed to the worktable 200 by screws, so that the position of the limiting plates 230 can be pre-adjusted according to the shape of the workpiece 1, adapting to workpieces of different specifications, ensuring the stability of the workpiece 1, and not causing excessive squeezing damage to the surface of the workpiece 1. It is especially suitable for fixing irregularly shaped workpieces, improving the equipment's adaptability to workpieces of different shapes.

[0040] like Figure 2 As shown, a sensor 240 is installed on the workbench 200. The sensor 240 is used to detect whether the workpiece 1 on the workbench 200 is installed in place. The real-time monitoring of the sensor 240 ensures that cutting is only performed when the workpiece 1 is fully placed in place, reducing the risk of saw blade damage or equipment failure caused by the workpiece 1 being loose, and improving safety during cutting.

[0041] like Figure 2 and Figure 4 As shown, a support member 250 is provided on the worktable 200. The support member 250 includes a support plate 251 and a support rod 252. The support plate 251 is fixedly connected to the worktable 200, and one end of the support rod 252 is fixedly connected to the support plate 251, while the other end abuts against the scrap portion 10 on the workpiece 1. During operation, after the workpiece 1 is fixed on the worktable 200, the top end of the support rod 252 abuts against the bottom of the scrap portion 10, providing direct support force to the scrap portion 10. When the saw blade 680 of the cutting assembly 600 contacts the scrap portion 10 for cutting, the scrap portion 10 is prone to sagging or deformation due to the cutting force of the saw blade 680. The support rod 252 can transmit the force to the worktable 200 through the support plate 251, offsetting the downward pressure brought by the cutting force, maintaining the stability of the workpiece 1, and thus ensuring the accuracy of the cutting.

[0042] like Figure 5As shown, the flipping assembly 300 includes a support base 310, a flipping seat 320, and a flipping motor 330. The flipping seat 320 is rotatably mounted on the support base 310, and the flipping motor 330 is fixed to the support base 310 to drive the flipping seat 320 to rotate, thereby causing the worktable 200 to rotate circumferentially around the X-axis. When the scrap portion 10 on the workpiece 1 is in a non-horizontal or tilted state and needs to be adjusted to an angle suitable for saw blade cutting, the flipping motor 330 starts, driving the flipping seat 320 to rotate around the rotation axis on the support base 310 through the transmission structure, thereby causing the worktable 200 and the workpiece 1 to rotate synchronously around the X-axis until the scrap portion 10 is adjusted to a preset angle. The multi-angle flipping of the worktable 200 is achieved by driving it with the flipping motor 330, replacing the tedious manual adjustment of the workpiece 1 angle. This not only reduces labor intensity but also allows for precise angle adjustment through the precise control of the flipping motor 330.

[0043] like Figure 5 As shown, the rotating assembly 400 includes a rotary motor 410 and a rotating disk 420. The rotating disk 420 is rotatably mounted on the tilting base 320. The worktable 200 is fixedly connected to the rotating disk 420. The rotary motor 410 is located on the side of the tilting base 320 opposite to the rotating disk 420 and is used to drive the rotating disk 420 to rotate around the Z-axis. When it is necessary to adjust the circumferential position of the workpiece 1 on the horizontal plane, the rotary motor 410 starts, driving the rotating disk 420 to rotate on the tilting base 320 through gear transmission or belt transmission, thereby driving the worktable 200 and the workpiece 1 fixed thereto to rotate synchronously around the Z-axis until the target waste section 10 is aligned with the saw blade 680 of the cutting assembly. Without the need to disassemble and re-clamp the workpiece 1, the rotary motor 410 can drive the workpiece to achieve precise rotation and positioning at any angle of 360°, significantly shortening the cutting time of the waste section and improving production efficiency.

[0044] It is worth noting that the flipping component 300 and the rotating component 400 work together to satisfy any posture adjustment of the workpiece in space.

[0045] The moving assembly 500 includes a drive motor 510, a lead screw 520, and a moving block 530. One end of the lead screw 520 is coaxially and fixedly connected to the output shaft of the drive motor 510, and the other end is fixed to the bearing seat 110 of the frame 100 via a bearing 540. The moving block 530 is threadedly connected to the lead screw 520 and fixedly connected to the support base 310. After the drive motor 510 starts, it drives the lead screw 520 to rotate around its own axis. Since the lead screw and the moving block 530 are threadedly engaged, the rotational motion of the lead screw 520 is converted into the linear motion of the moving block 530 along the axial direction of the lead screw 520. In turn, the moving block 530 drives the support base 310 and the connected tilting assembly 300, rotating assembly 400, and worktable 200 to move as a whole along the Y-axis.

[0046] To further improve the stability of the worktable 200's movement along the Y-axis, a pair of guide rails 120 are also provided on the frame 100. The pair of guide rails 120 are respectively located on both sides of the support base 310, and sliders 311 that are slidably connected to the guide rails 120 are fixed on the support base 310. In addition, a retractable protective cover 130 is also provided on the frame 100. The protective cover 130 covers the guide rails 120 to prevent dust generated during sawing from falling onto the guide rails 120, thereby affecting the normal operation of the worktable 200 in the Y-axis direction.

[0047] like Figure 6 As shown, the cutting assembly 600 includes a fixed base 610, a first motor 620, a first swing arm 630, a second motor 640, a second swing arm 650, and a third motor 660. The fixed base 610 is fixed on the frame 100. The first motor 620 is fixed on the fixed base 610 and its output end is connected to one end of the first swing arm 630. The second motor 640 is fixed to the other end of the first swing arm 630 and its output end is connected to one end of the second swing arm 650. The third motor 660 is fixed to the other end of the second swing arm 650 and its output end is connected to the saw blade 680. During operation, the third motor 660 drives the saw blade 680 to rotate at high speed. When the position of the saw blade 680 needs to be adjusted, the first motor 620 drives the first swing arm 630 to rotate around the fixed base 610, realizing a wide range of movement of the saw blade 680 in the XZ plane. The second motor 640 drives the second swing arm 650 to rotate relative to the first swing arm 630, completing the fine adjustment of the position of the saw blade 680, ultimately enabling the high-speed rotating saw blade 680 to precisely fit against the waste section 10 to complete the cut. Its beneficial effects are that the double swing arm structure gives the saw blade 680 excellent flexibility, which can cover complex trajectories in the XZ plane and adapt to the cutting needs of various irregularly shaped waste sections; the three motors have clear division of labor, respectively responsible for saw blade rotation, wide range of displacement and fine positioning, which can ensure both cutting efficiency and cutting accuracy.

[0048] The other end of the second swing arm 650 is equipped with a turret tool magazine 670, on which multiple saw blades 680 are mounted. When it is necessary to cut waste material 10 of different materials (such as metal or plastic) or different thicknesses, the turret tool magazine 670 can rotate rapidly under the command of the control system to switch the preset matching saw blade 680 to the working position, thereby replacing the current saw blade 680 to complete the cutting operation.

[0049] like Figure 7 As shown, the sawing machine also includes a housing 700, which is fixed above the frame 100. The worktable 200, the tilting component 300, the rotating component 400, the moving component 500, and the cutting component 600 are located inside the housing 700, reducing the impact of sawing powder and waste on the working environment.

[0050] Optionally, the housing 700 is provided with a feed inlet 710, and the moving component 500 is located outside the housing 700, passing at least partially through the feed inlet 710. The moving component 500 can drive the worktable 200 to move to the outside of the housing 700 to facilitate loading.

[0051] Optionally, an automatic door 720 is provided at the feed inlet 710. The automatic door 720 can move along the Z-axis to close the feed inlet 710 during sawing to prevent the powder generated during sawing from scattering.

[0052] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
