Description

Technical Field

[0001] This utility model relates to the field of saw table protection technology, and in particular to an adjustable saw table protection device. Background Technology

[0002] A sliding table saw is a widely used woodworking power tool, a multi-functional saw used for cutting straight lines and curves. The basic principle of a sliding table saw is to use a high-speed rotating saw blade to cut materials such as wood, plastic, and metal. The cutting direction is controlled by a handle, allowing the saw to precisely cut the desired shape. A sliding table saw consists of a motor, saw body, saw blade, and base. The saw blade is one of the most important components; different blade sizes are typically selected based on the needs, for example, a thinner blade for cutting curves and a wider blade for cutting straight lines.

[0003] During normal use, the saw blade of a sliding table saw is partially exposed to the air, and the saw blades vary in size. The length of the exposed saw blade varies depending on its diameter. To prevent workers from getting their clothes damaged or their limbs cut by the saw blade when it is not in use or when cleaning the table, a protective device that can be adjusted according to the length of the exposed saw blade is needed. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems by providing an adjustable saw table protection device.

[0005] To address the aforementioned problems, an adjustable saw table protection device is provided, characterized by comprising a saw table, a cutting mechanism, and a protective structure. The protective structure includes a lifting motor, a shield, a guide rod, a guide rail, a mounting base, and a lifting gear. The shield vertically penetrates the upper surface of the saw table and extends into the saw table cavity. Lifting motors are arranged on both sides of the shield within the saw table cavity. The output end of the lifting motor passes through the mounting base, and a lifting gear is arranged within the mounting base. Saw teeth that cooperate with the lifting gear are provided on both sides of the shield. Rotation of the lifting gear allows the shield to move vertically.

[0006] Preferably, the shield is provided with a guide rod, and the guide rail is disposed in the saw table cavity and is used in conjunction with the guide rod.

[0007] Preferably, a clearance groove is provided on one side of the shield.

[0008] Preferably, the cutting mechanism includes a cutting motor and a saw blade. The output end of the cutting motor is located in the clearance groove and is bolted to the saw table cavity. The saw blade is penetrated by the output end of the cutting motor and is located inside the shield.

[0009] Preferably, the top of the saw blade extends beyond the upper surface of the saw table.

[0010] Preferably, the lateral length of the shield exceeds the longest diameter of the saw blade used, and the height dimension is greater than the radius of the largest saw blade.

[0011] In summary, the beneficial effects of this utility model are:

[0012] This utility model modifies some of the structure so that when protection is needed after cutting, the lifting motor is started, and the output end of the lifting motor drives the lifting gear to rotate. After the lifting gear rotates, it pushes the shield to move upward until the part of the top of the saw blade that is exposed on the saw table is completely covered. This can prevent workers from getting their clothes damaged or their limbs cut by the saw blade when the saw blade is not working or when cleaning the saw table. At the same time, the extension length of the shield can be adjusted according to the length of the saw blade used. Attached Figure Description

[0020] Please see Figure 1-3 As shown, the device includes a saw table 1, a cutting mechanism, and a protective mechanism. The protective structure includes a lifting motor 214, a shield 2, a guide rod 213, a guide rail 212, a mounting base 216, and a lifting gear 215. The shield 2 extends vertically through the upper surface of the saw table 1 and into the cavity of the saw table 1. Lifting motors 214 are installed on both sides of the shield 2 inside the cavity of the saw table 1. The output end of the lifting motor 214 passes through the mounting base 216. The lifting gear 215 is installed inside the mounting base 216. Saw teeth that cooperate with the lifting gear 215 are provided on both sides of the shield 2. When the lifting gear 215 rotates, the shield 2 can move vertically.

[0021] Furthermore, the shield 2 is provided with a guide rod 213, and the guide rail 212 is provided in the cavity of the saw table 1 and is used in conjunction with the guide rod 213.

[0022] Furthermore, a clearance groove 211 is provided on one side of the shield 2.

[0023] Furthermore, the cutting mechanism includes a cutting motor 311 and a saw blade 3. The output end of the cutting motor 311 is located in the clearance groove 211 and is connected to the cavity of the saw table 1 by a cutting bolt. The saw blade 3 is penetrated by the output end of the cutting motor 311 and is located inside the shield 2.

[0024] Furthermore, the top of the saw blade 3 extends beyond the upper surface of the saw table 1.

[0025] Furthermore, the lateral length of the shield 2 exceeds the longest diameter of the saw blade 3 used, and its height dimension is greater than the radius of the largest saw blade 3.

[0026] In practical applications, when protection is required after cutting, the lifting motor 214 is activated, causing the output end of the lifting motor 214 to drive the lifting gear 215 to rotate. After the lifting gear 215 rotates, it pushes the shield 2 to move upward until the part of the top of the saw blade 3 that is exposed on the saw table 1 is completely covered. This can prevent workers from having their clothes damaged or their limbs cut by the saw blade 3 when the saw blade 3 is not working or when cleaning the saw table 1. At the same time, the extension length of the shield 2 can be adjusted according to the length of the saw blade 3 used.
