Description

Technical Field

[0001] The utility model relates to the technical field of woodworking cutting equipment, and particularly relates to a portable folding saw table. Background Art

[0002] With the development of the national economy, people's requirements for the living environment are gradually increasing. When decorating the home environment, decorators often need to use a woodworking electric saw in residential houses for home production and cutting of decoration materials. Most of the existing saw tables are fixed. In order to facilitate the operator to perform cross-cutting and vertical cutting on the board, multiple extension brackets need to be set, resulting in a large volume of the saw table, a large floor area for storage, inconvenient disassembly, assembly and handling, time-consuming and laborious. When sawing materials, it is necessary to repeatedly calibrate before operation, with low work efficiency. In addition, when the main workbench of the existing saw table encounters uneven ground, its height cannot be adjusted to make up for the uneven ground defect, which affects the processing accuracy and quality. Summary of the Utility Model

[0003] The utility model aims at the defects existing in the prior art and provides a portable folding saw table.

[0004] The technical solution adopted by the utility model to solve its technical problems is as follows:

[0005] A portable folding saw table includes a main workbench, a side extension frame and a swing arm steering mechanism. The main workbench is composed of a frame, a tabletop and four legs. Four folding seats are installed around the bottom of the frame. An arc-shaped guide rail is provided on each folding seat. The heights of the arc-shaped guide rails on the two folding seats on the same side are different. The four legs are respectively fixed in the arc-shaped guide rails on the corresponding folding seats through bolts. Adjusting bolts are arranged between the tabletop and the frame. The side extension frame is clamped in the guide rail on the side of the tabletop. The swing arm steering mechanism includes a telescopic swing arm bracket, a swing arm, a steering bearing, a linear bearing and a linear guide rail. The telescopic swing arm bracket is arranged on the side of the frame. The swing arm is movably connected to the steering bearing of the telescopic swing arm bracket. The swing arm is connected to the linear guide rail through a linear bearing at its end. The side extension frame is connected to the bracket on the top of the linear guide rail. The telescopic swing arm bracket is provided with a swing arm small leg.

[0006] A number of guide rollers are installed on the above-mentioned side extension frame.

[0007] A side extension plate and a front extension plate are respectively installed on the side part and the front part of the above-mentioned main workbench. The front extension plate is inserted into the front part of the main workbench.

[0008] The tabletop of the saw table of the present utility model adopts an adjustable design. The adjustment bolts between the tabletop and the table frame are not only used for fixing the tabletop, but also can adjust the levelness of the tabletop when installing the tabletop, so that the tabletop of the saw table has better flatness after adjustment, thereby obtaining higher cutting accuracy; the legs of the saw table have a folding and storage structure, and the two legs on the same side are respectively installed in arc-shaped guide rails at different heights, so as to realize the staggered folding and storage of the two legs on the same side; the side extension frame is installed on the swing arm steering mechanism, and the swing arm steering mechanism adopts a two-section swing arm structure. The first section is the swing arm bracket, and the swing arm bracket is a front-back telescopic structure. When in use, the swing arm bracket extends and is fixed, so that the swing range of the swing arm is wider, thereby realizing that the saw table obtains a larger cutting range under the condition of a shorter swing arm structure. At the same time, the swing arm bracket is synchronously equipped with small legs, which greatly improves the stability and safety of the saw table during use. The second section is the swing arm structure. Through the two-section structure design, the saw table of the present utility model has a shorter swing arm structure, thereby greatly improving the rigidity and stability of the swing arm, so that the saw table obtains higher accuracy and stability during cutting.

[0009] The main workbench, side extension frame, side extension plate and front extension plate of the saw table of the present utility model all adopt folding or snap-fit structures, which fully consider the convenience of on-site handling of the saw table on the premise of ensuring the use strength, and effectively improve the portability of the saw table.

Detailed Embodiments

[0016] As Figure 1 , Figure 2 , Figure 3 andFigure 4 As shown in the figure, a portable folding saw table includes a main workbench, a side extension frame 7 and a rocker arm steering mechanism. The main workbench is composed of a bench frame 1, a table top 2 and four legs 3. Four folding seats 4 are installed around the bottom of the bench frame 1. An arc-shaped guide rail 5 is provided on each folding seat 4. The heights of the arc-shaped guide rails 5 on the two folding seats 4 on the same side are different. The four legs 3 are respectively fixed in the arc-shaped guide rails 5 on the corresponding folding seats through bolts. An adjustment bolt 6 is provided between the table top 2 and the bench frame 1. The side extension frame 7 is clamped in the guide rail 8 on the side of the table top 2. The rocker arm steering mechanism includes a telescopic rocker arm support 9, a rocker arm 10, a steering bearing 11, a linear bearing 12 and a linear guide rail 13. The telescopic rocker arm support 9 is arranged on the side of the bench frame 1. The rocker arm 10 is movably connected to the steering bearing 11 of the telescopic rocker arm support 9. The rocker arm 10 is connected to the linear guide rail 13 through the linear bearing 12 at the end. The side extension frame 7 is connected to the support on the top of the linear guide rail 13. The telescopic rocker arm support 9 is provided with a rocker arm small leg 14. A plurality of material guide rollers 15 are installed on the side extension frame 7. A side extension plate 16 and a front extension plate 17 are respectively installed on the side and front of the main workbench. The front extension plate 17 is inserted into the front part of the main workbench.

[0017] The table top of the saw table of the present utility model adopts an adjustable design. The adjustment bolt between the table top and the bench frame is not only used for fixing the table top, but also can adjust the levelness of the table top when the table top is installed, so that the table top of the saw table has better flatness after adjustment, thereby obtaining higher cutting accuracy; the legs of the saw table have a folding and storage structure, and the two legs on the same side are respectively installed in the arc-shaped guide rails at different heights, so as to realize the staggered folding and storage of the two legs on the same side; the side extension frame is installed on the rocker arm steering mechanism, and the rocker arm steering mechanism adopts a two-stage rocker arm structure. The first stage is the rocker arm support, and the rocker arm support is a front and back telescopic structure. When in use, the rocker arm support extends and is fixed, so that the swing range of the rocker arm is wider, thereby realizing that the saw table has a larger cutting range under the condition of a shorter rocker arm structure. At the same time, the rocker arm support is synchronously equipped with small legs, which greatly improves the stability and safety of the saw table when in use. The second stage is the rocker arm structure. Through the two-stage structure design, the saw table has a shorter rocker arm structure, thereby greatly improving the rigidity and stability of the rocker arm, so that the saw table obtains higher precision and stability during cutting.
