Description
Technical field
The utility model is related to auto parts and components manufacturing equipment field, more particularly to projection welding bottom electrode holding rod component.
Background technology
Projection welding process is very universal in auto parts welding production.In existing projection welding production process, electricity under projection welding
Often occur to fall into the phenomenon for causing internal mechanism stuck in holding rod component, maintenance time due to welding slag in the holding rod component of pole
It is long, affect production efficiency.It is generally used for bottom electrode holding rod side and is passed through compressed air, passes through compressed air in welding process
Prevent welding slag from falling in bottom electrode holding rod component.In because of lower electricity group holding rod component, on, lower part is all hatch frame, therefore compresses
Air deslagging effect is poor, still blocks frequent in bottom electrode holding rod.
Utility model content
For the shortcoming of above-mentioned existing projection welding bottom electrode holding rod component deslagging effect difference, applicant is studied and is improved,
A kind of projection welding bottom electrode holding rod modular construction is provided.
In order to solve the above problems, the utility model adopts following scheme：
A kind of projection welding bottom electrode holding rod modular construction, including bottom electrode, be installed on the alignment pin of bottom electrode upper end, be nested with institute
State the bottom electrode holding rod of bottom electrode and be installed on below bottom electrode the displacement sensor rod being placed in bottom electrode holding rod, alignment pin
Chock is installed between lower surface and the upper end of displacement sensor rod draw-in groove and insulation chock, the side of the bottom electrode holding rod are installed
With compressed air inlet, the lower end of the alignment pin has the first oblique anchor ring, and the lower surface of bottom electrode is with described first
The second oblique anchor ring that tiltedly anchor ring coordinates；Sealing ring is installed in the displacement sensor rod, sealing ring and chock are installed between draw-in groove
Spring is installed, the lower end side face of sealing ring has a 3rd oblique anchor ring, the inner peripheral surface of bottom electrode holding rod have it is inwardly projecting, and
The 4th oblique anchor ring that the 3rd oblique anchor ring coordinates.
It is of the present utility model to have technical effect that：
In the utility model, by the cooperation between sealing ring and bottom electrode holding rod, in projection welding so that compression is empty
Gas can only be sprayed from bottom electrode holding rod top, improve compressed air deslagging function, be effectively prevent welding slag and fallen into bottom electrode and hold
In bar.

Specific embodiment
Below in conjunction with the accompanying drawings specific embodiment of the present utility model is described further.
As shown in Figure 1 to Figure 3, the projection welding bottom electrode holding rod modular construction of the present embodiment, including bottom electrode 2, it is installed on down
The alignment pin 1 of 2 upper end of electrode, the bottom electrode holding rod 3 for being nested with bottom electrode 2 and be installed on and bottom electrode be placed in below bottom electrode 2 and hold
Displacement sensor rod 8 in bar 3, is provided with chock and installs draw-in groove 5 between the lower surface of alignment pin 1 and the upper end of displacement sensor rod 8
And insulation chock 4, the lower end that the side of bottom electrode holding rod 3 has compressed air inlet 9, alignment pin 1 has the first oblique anchor ring 10,
The lower surface of bottom electrode 2 is with the second oblique anchor ring 11 coordinated with the first oblique anchor ring 10；Sealing ring is installed in displacement sensor rod 8
7, spring 6 is installed between sealing ring 7 and chock installation draw-in groove 5, the lower end side face of sealing ring 7 has the 3rd oblique anchor ring 12, under
The inner peripheral surface of electrode holder 3 has inwardly projecting, and the 4th oblique anchor ring 13 that coordinates of the 3rd oblique anchor ring 12.
As shown in figure 1, during unwelded state：Alignment pin 1 stretches out, and now the first oblique anchor ring 10 of 1 bottom of alignment pin is with
Second oblique anchor ring 11 of 2 lower end of electrode is fitted, and whole components mechanism upper space closure, compressed air enter compressed air from side
Entrance 9 is entered in bottom electrode holding rod 3, and most of compressed air is flowed out from bottom, can by the dust in bottom electrode holding rod 3 and
Little particle welding slag in falling within blows off.
As shown in Fig. 2 welded condition：Alignment pin 1 is depressed, and (placing nut on alignment pin 1, Top electrode is pushed, by nut
Plate to be welded is depressed into, so as to drive alignment pin 1 to push), displacement sensor rod 8 and alignment pin 1 are synchronously moved down, while sealing ring 7
3rd oblique anchor ring 12 is pressed to is fitted with the 4th oblique anchor ring 13 inside bottom electrode holding rod 3, lower space closure, is now compressed empty
Gas enters bottom electrode holding rod 3 from compressed air inlet 9, and mainly the gap between top alignment pin 1 and bottom electrode 2 sprays, can
To prevent in welding process, welding slag is fallen in bottom electrode holding rod 3 by the gap.
Displacement sensor rod 8 is moved with bottom electrode 2, is provided with displacement detecting sensor, welding process in bottom of device
In by detecting 1 volume under pressure of alignment pin preventing to weld neglected loading nut, the phenomenon such as wrongly installed part.
Embodiment provided above is better embodiment of the present utility model, only for convenient explanation the utility model, and
It is non-to make any pro forma restriction to the utility model, any those of ordinary skill in the art, if without departing from
In the range of the carried technical characteristic of the utility model, locally change or repair using done by the utility model disclosed technology content
The Equivalent embodiments of decorations, and without departing from technical characteristic content of the present utility model, still fall within the utility model technical characteristic
In the range of.
