Description

Technical Field

[0001] This utility model relates to the field of saw base technology, and in particular to a sliding seat for a portable saw. Background Technology

[0002] Portable saws are widely used in metal processing, pipe cutting, and on-site construction due to their high mobility and flexible operation. Their core component, the sliding base, supports the saw blade, guides the cutting direction, and adjusts the cutting position.

[0003] Traditional portable saws often use a simple slider and guide rail structure for the sliding seat, and the position is fixed by a side set screw. The set screw only acts on one side of the slider, and when tightened, it is easy to cause the slider to tilt, resulting in an angle between the cutting saw blade and the guide rail. During the cutting process, offset, rail biting, or saw cut skew will occur, which will seriously affect the cutting accuracy and saw blade life. Utility Model Content

[0018] This application provides a sliding base for a portable saw, comprising: Slide rail 1; The movable part 2 has two extension parts 3 at its bottom. The extension parts 3 are L-shaped and the two L-shaped extension parts are symmetrically arranged. The movable part 2 is slidably connected to the slide rail 1 through the two extension parts 3. The movable part 2 is provided with an assembly hole for the installation of the cutting saw. Bolt 4 passes through the through hole of movable part 2 and is connected to the threaded hole of connector 5. Connector 5 is slidably set in the inner groove of slide rail 1. Two assemblies 6 are respectively installed at both ends of the slide rail 1, and a connecting mechanism 7 is provided on the assembly 6; Through the technical solution of this utility model, the slide rail 1 provides a sliding guide foundation for the moving part 2, laying a guiding foundation for the stable cutting of the subsequent cutting saw. The two L-shaped extensions 3 at the bottom of the moving part 2 are symmetrically arranged. The L-shaped structure limits the sliding direction of the moving part 2. The assembly hole on the moving part 2 provides an installation carrier for the cutting saw, ensuring cutting accuracy. The bolt 4 passes through the through hole of the moving part 2 and is connected to the threaded hole of the connecting part 5. The connecting part 5 is slidably set in the inner groove of the slide rail 1. Tightening the bolt 4 pushes the connecting part 5 to press against the inner groove wall of the slide rail 1, realizing the quick locking of the moving part 2 at any position on the slide rail 1. Loosening the bolt 4 pushes the moving part 2 to flexibly adjust its position to adapt to the cutting needs of workpieces of different lengths and improve the operational flexibility. The connecting mechanism 7 on the two assembly parts 6 is used for the quick connection or disassembly of the slide rail 1 with other components, improving the ease of assembly and portability of the device.

[0019] During use, the connecting mechanism 7 includes: The threaded post 71 is connected to the threaded through hole of the assembly 6, and a support plate 72 is rotatably mounted on the threaded post 71. An extension shaft 73 is slidably mounted inside the shaft cavity of the threaded column 71, and a clamping plate 74 is rotatably mounted on the extension shaft 73. The drive mechanism 75 is mounted on the threaded post 71 and is used to adjust the distance between the support plate 72 and the clamping plate 74. A locking element 76 is provided on the threaded post 71, and the locking element 76 is connected to the assembly 6; An adjusting cap 77 is provided at the end of the threaded column 71, and an anti-slip structure is provided on the adjusting cap; Through the technical solution of this utility model, the threaded column 71 is connected to the threaded through hole of the assembly 6. By rotating and adjusting the length of the threaded column 71 extending out of the assembly 6, the support height of the slide rail 1 can be adjusted to adapt to the cutting support requirements of different work sites with different ground height differences or workpieces of different thicknesses. The clamping plate 74 rotatably set at the end of the extension shaft 73 cooperates with the support plate 72 set at the end of the threaded column 71. The distance between the two is adjusted by the drive mechanism 75 to adapt to auxiliary support components of different thicknesses and achieve stable clamping of the support components. The locking part 76 on the threaded column 71 is connected to the assembly 6. After the support height of the slide rail 1 is adjusted to the position, the relative position of the threaded column 71 and the assembly 6 is quickly locked to prevent the threaded column 71 from loosening due to vibration during the cutting operation.
