Table saw lifting base with embedded stator and rotor

Abstract

A table saw lifting base with an embedded stator and rotor includes: a fixed base; a metal lifting base movably disposed on the fixed base, the metal lifting base having a through hole and a hole wall formed around the hole; a lifting drive disposed on the fixed base for operating the metal lifting base to raise or lower; a stator-rotor assembly disposed in the hole, the stator-rotor assembly having a stator, a rotor, and a drive shaft, the stator contacting the hole wall of the hole, the drive shaft being disposed on the rotor and extending out of the hole; and a circular saw blade disposed on the drive shaft and driven to rotate by the drive shaft.

Claims

1. A table saw lifting base with an embedded stator and rotor, for mounting on a table of a saw, the table having a slit, the table saw lifting base comprising: a fixed base disposed on the table; a metal lifting base movably disposed on the fixed base, the metal lifting base having a through-hole, the metal lifting base forming a hole wall around the hole; a lifting drive disposed on the fixed base for operating to drive the metal lifting base to rise or fall; a stator-rotor assembly disposed in the hole, the stator-rotor assembly having a stator, a rotor and a drive shaft, the stator contacting the hole wall of the hole, the drive shaft being disposed on the rotor and extending out of the hole; and a circular saw blade disposed on the drive shaft, driven by the drive shaft to rotate, the circular saw blade having a portion extending upward through the slit and protruding from the table, the circular saw blade changing its height protruding from the table as the metal lifting base rises and falls.

2. The table saw lifting base with embedded stator and rotor as described in claim 1, wherein: The metal lifting platform is made of aluminum.

3. The table saw lifting base with embedded stator and rotor as described in claim 1, wherein: The fixed base has two slide rails, and the metal lifting base is movably mounted on the two slide rails and can be driven by the lifting drive to move up and down along the two slide rails.

4. The table saw lifting base with embedded stator and rotor as described in claim 1, wherein: The top of the metal lifting seat has a top edge, and a protrusion extends upward along the top edge. The hole partially penetrates the protrusion, while the rest penetrates the metal lifting seat.

5. The table saw lifting base with embedded stator and rotor as described in claim 4, wherein: The outer surface of the bump has multiple heat dissipation fins extending outward.

6. The table saw lifting base with embedded stator and rotor as described in claim 4, wherein: The cross-sectional area of ​​the portion of the recessed hole that penetrates the protrusion is larger than the cross-sectional area of ​​the portion of the recessed hole that penetrates the metal lifting seat.

7. The table saw lifting base with embedded stator and rotor as described in claim 1, wherein: It also includes a motor drive located on the metal lifting base.
