In existing technology, single-blade sawing machines have a simple structure and are suitable for cutting workpieces with a single cross-section. There are also double-blade sawing devices that can cut both sides or different positions of the workpiece simultaneously, improving processing efficiency. However, existing double-blade structures mostly have adjustable spacing, but the cutting angle of the workpiece is not adjustable. A flat cut must be performed first before an angled cut can be made, adding extra steps and reducing cutting efficiency. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figure 1A workpiece sawing device includes a support frame 2 and a lifting mechanism 1 capable of driving the support frame 2 to move up and down. The support frame 2 is equipped with a power shaft 18 and a rotary motor 17 that drives the power shaft 18. The power shaft 18 is a telescopic shaft with adjustable length. Each end of the power shaft 18 is provided with a set of sawing components 3. The sawing components 3 are assembled with the support frame 2 in an adjustable position. The support shaft 8 of the sawing components 3 is connected to the power shaft 18 through a universal joint 9.

[0018] When the device is working, the rotary motor 17 outputs power, which drives the power shaft 18 to rotate through transmission. The power shaft 18 is an adjustable telescopic shaft. By sliding fit, the axial length of both ends can be changed, thereby changing the distance between the sawing components 3 located at both ends, realizing the adjustment of the distance between the two saw blades to accommodate workpieces of different widths. The two ends of the power shaft 18 are respectively connected to the support shaft 8 of their respective sawing components 3 through universal joints 9, which enables the adjustment of the cutting angle of the sawing components 3. In use, the distance and cutting angle of the two sawing components 3 are first adjusted, and then the lifting mechanism 1 drives the support frame 2 to move downward, completing the segment cutting and corner cutting in one go.

[0019] The device enables rapid adjustment of the spacing between the two sets of sawing components 3 through the telescopic structure of the power shaft 18, allowing it to adapt to workpieces of various widths without changing the equipment. Through the adjustable connection between the sawing component 3 and the support frame 2, combined with the transmission compensation function of the universal joint 9, the saw blade cutting angle can be flexibly adjusted, enabling various cutting processes such as straight cutting, beveling, and chamfering, thus improving processing efficiency.

[0020] The power shaft 18 includes a first shaft 15 and a second shaft 16 that are slidably connected. The first shaft 15 is rotatably connected to a first support ring 10. The first support ring 10 is fixedly connected to a second connecting rod 11. The top end of the second connecting rod 11 is fixedly connected to a second slide block 12. The second slide block 12 is slidably connected to the support frame 2 and the two are locked together by locking bolts. The second shaft 16 is rotatably connected to a second support ring 13. The second support ring 13 is fixedly connected to a third connecting rod 14. The third connecting rod 14 is fixed to the support frame 2.

[0021] The power shaft 18 consists of a first shaft 15 and a second shaft 16 that are slidably connected. The first shaft 15 can slide relative to the second shaft 16 along the axial direction, thereby realizing the length change of the power shaft 18. One end of the first shaft 15 is rotatably connected to a first support ring 10, and the first support ring 10 is fixedly connected to a second connecting rod 11. The top end of the second connecting rod 11 is fixedly connected to a second slide block 12, which is slidably fitted to the support frame 2 and fixed by a locking bolt. When the locking bolt is loosened, the second slide block 12 can slide along the support frame 2, causing the first shaft 15 to extend or retract relative to the second shaft 16, thereby realizing the length adjustment of the power shaft 18. One end of the second shaft 16 is rotatably connected to a second support ring 13, and the second support ring 13 is fixedly connected to a third connecting rod 14. The third connecting rod 14 is fixed to the support frame 2 and is used to provide stable support for the second shaft 16 during the adjustment process. Through the sliding engagement of the first rotating shaft 15 and the second rotating shaft 16, and combined with the sliding and locking structure of the second slide block 12 and the support frame 2, the power rotating shaft 18 can quickly change its length without disassembly, so that the distance between the sawing components at both ends can be flexibly adjusted according to the workpiece width.

[0022] As a sliding connection method, the first rotating shaft 15 is a cylindrical structure with a multi-prism insertion hole, and the second rotating shaft 16 is a multi-prism structure. The second rotating shaft 16 is inserted into the multi-prism insertion hole of the first rotating shaft 15, and the two are slidably connected by plugging.

[0023] The power output shaft of the rotary motor 17 is connected to the second rotating shaft 16 via a sprocket assembly, pulley assembly, or gear assembly. This connection enables the second rotating shaft 16 to obtain rotational power during operation.

[0024] The sawing assembly 3 includes a U-shaped frame 7, a supporting shaft 8 rotatably connected to the U-shaped frame 7, a saw blade 19 coaxially fixedly mounted on the supporting shaft 8, and the U-shaped frame 7 connected to the support frame 2 through a position adjustment mechanism. The position adjustment mechanism includes a rotatably connected connecting seat 4 and a first connecting rod 6. The connecting seat 4 is locked to the first connecting rod 6 by a locking bolt, the first connecting rod 6 is fixed to the U-shaped frame 7, and a first sliding seat 5 is fixedly connected to the connecting seat 4. The first sliding seat 5 is slidably connected to the support frame 2 and the two are fixed by a locking bolt.

[0025] The supporting shaft 8 is supported by a U-shaped frame 7 and is rotatably connected to the U-shaped frame 7 to ensure stable rotation at different angle positions. The U-shaped frame 7 is connected to the support frame 2 through a position adjustment mechanism. In the position adjustment mechanism, one end of the first connecting rod 6 is fixed to the U-shaped frame 7, and the other end is locked to the connecting seat 4. The connecting seat 4 can rotate around its rotation connection point, thereby driving the first connecting rod 6 and the U-shaped frame 7 to achieve angle adjustment. The connecting seat 4 is fixedly connected to a first slide 5, which is slidably connected to the support frame 2 and fixed in position by a locking bolt. When the locking bolt is loosened, the first slide 5 can slide along the support frame 2, realizing the position adjustment of the sawing assembly 3 on the support frame 2.

[0026] The saw blade 19 obtains stable power through the transmission connection between the rotary motor 17 and the second rotating shaft 16, thus achieving cutting. The rotational cooperation between the U-shaped frame 7 and the supporting rotating shaft 8 ensures that the saw blade maintains stable rotation at different angles. The position adjustment mechanism enables the sawing assembly 3 to simultaneously achieve position and angle adjustment. The sliding of the first slide block 5 along the support frame 2 achieves the horizontal positioning of the saw blade. The rotational cooperation between the connecting seat 4 and the first connecting rod 6 enables flexible changes in the cutting angle.

[0027] Universal joint 9 is a double universal joint or a telescopic double universal joint; lifting mechanism 1 is one of a hydraulic cylinder, a pneumatic cylinder, an electric hydraulic actuator, or a ball screw mechanism.

[0028] Universal joint 9 is a double universal joint or a telescopic double universal joint. During power transmission, it can compensate for the axial offset and angle change between the support shaft 8 and the power shaft 18 caused by the adjustment of the cutting angle. This ensures that the support shaft 8 can still obtain stable and continuous rotational power at different angle positions, and reduces speed fluctuations and transmission shocks caused by angle changes. The lifting mechanism 1 can be one of a hydraulic cylinder, pneumatic cylinder, electric hydraulic actuator, or ball screw mechanism. It is installed on the frame and connected to the support frame 2. By driving the support frame 2 to move up and down, it realizes the cutting movement of the saw blade 19 in the height direction.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any technical solution, concept, or design obtained by those skilled in the art by making equivalent substitutions or changes based on the technical solution and utility model concept disclosed in the present utility model should be included within the protection scope of the present utility model.
