Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the side view of the utility model；
Fig. 3 is the C-C of Fig. 2 to cross-sectional view.
Specific embodiment
In conjunction with Fig. 1 to Fig. 3, a specific embodiment of the utility model is described in detail, but not to the power of the utility model
Benefit requires to do any restriction.
As shown in Figure 1 to Figure 3, a kind of servo pressurization mechanism for resistance welder, including servo motor 1, first are installed
Seat the 2, the second mounting base 3 and link block 4 for connecting pressurized component is provided with lead screw 5 in the first mounting base 2 and lead screw is solid
It reservation 6, lead screw 5 and the concentric setting of the first mounting base 2 and is fixed in lead screw fixing seat 6,6 surrounding of lead screw fixing seat is fixed on
On first mounting base, 2 inner wall, the concentric side for being connected to the first mounting base 2 of the second mounting base 3, inside be equipped with guiding square shaft 7,
Linear guide 8 and section are the sliding block 9 of concave shape, are oriented to square shaft 7 and the concentric setting of the second mounting base 3, and one end protrudes into the
In one mounting base 2, the other end is connect after stretching out the second mounting base 3 with link block 4, and guiding square shaft 7 protrudes into the first mounting base 2
One end end face center has through-hole 71, and through-hole is fixed with feed screw nut 10, one end of lead screw 5 towards the first mounting base on one side
It is protruded into after feed screw nut 10 in through-hole 71, servo motor 1 is set to outside the first mounting base 2, and output shaft protrudes into the first installation
Pass through the concentric connection of the other end of shaft coupling 11 and lead screw 5 after in seat 1, linear guide 8 is embedded in a side of guiding square shaft 7
