Specific embodiment
In the following, being described further in conjunction with attached drawing and specific embodiment to the present invention:
As shown in figures 1-4, a kind of mash welder, including mash welder main body (not shown) further include electrode 1,2 and of elastic component
Clamping piece 3, electrode 1 are connected to mash welder main body, and clamping piece 3 is fixedly connected on mash welder main body, and clamping piece 3 includes hollow chamber
Room (not shown), one end of elastic component 2 and the insulation of electrode 1 connect, and the other end is connected to clamping piece 3, and electrode 1 is from top to bottom successively
Slidably it is connected to elastic component 2 and chamber.
Since clamping piece 3 is fixedly connected on mash welder main body, clamping piece 3 will not because of gravity effect and fall；
Since electrode 1 is connected to mash welder main body, electrode 1 successively can slidably be connected to elastic component 2 and chamber from top to bottom, not have
When being subjected to, due to the effect of elastic component 2, one end of electrode 1 towards clamping piece 3 does not pass through the sky of clamping piece 3
Chamber, therefore will not be electrically connected with pin 7, even if pin 7 is installed to clamping piece 3 by worker, weld job will not be carried out,
It can prevent worker from getting an electric shock；When needing to be subjected to, pin 7 is mounted on clamping piece 3, and worker operation electrode 1 makes
Electrode 1 moves downward and passes through cavity, contacts with pin 7, elastic component 2 is compressed at this time；Due to electrode 1 and mash welder main body
Electrical connection, thus electrode 1 contacted with pin 7 after when the conduction of pin 7, to carry out weld job, pin 7 is welded to specific bit
It sets；After the completion of welding, worker is stopped operation, and due to the effect of elastic component 2, original position is restored to moving electrode 1, is so followed
Ring is reciprocal.Meanwhile pin 7 is clamped by clamping piece 3, it realizes spot welding of the pin 7 on mash welder, without using welding gun, reduces
Cost, also reduces the labor intensity of worker；Due to the effect of elastic component 2, electrode 1 will not connect with pin 7 when installing pin 7
Touching, and electrode 1 will not be directly contacted when staff's installation pin, worker's Danger Electric shock risk is effectively reduced, it is safer.
As depicted in figs. 1 and 2, which further includes first sleeve 4, second sleeve 5 and fixing piece 6, and electrode 1 includes the
One flange 11, clamping piece 3 is fixedly connected on mash welder main body by fixing piece 6, and is preferably welded to connect；Electrode 1 from upper and
Under be successively slidably connected to first sleeve 4, elastic component 2, second sleeve 5 and chamber, clamping piece 3 includes the second flange 31, folder
One end of gripping member 3 towards the first flange 11 is nested in second sleeve 5, and the second flange 31 is abutted with second sleeve 5, first set
Cylinder 4 is abutted with the first flange 11, and one end of elastic component 2 is abutted with first sleeve 4, and the other end and the second sleeve 5 of elastic component 2 are supported
It connects；When not being subjected to, since first sleeve 4 is abutted with the first flange 11, under the action of elastic component 2, electrode 1
The cavity of clamping piece 3 is not passed through towards one end of clamping piece 3, the pin 7 that will not be clamped with clamped part 3 contacts, therefore not
It can be electrically connected with pin 7；When needing to be subjected to, since first sleeve 4 is abutted with the first flange 11, with electrode 1
It moves downward, the first flange 11 drives first sleeve 4 to move downward, and elastic component 2 is compressed at this time, after electrode 1 is contacted with pin 7
When pin 7 it is conductive, to carry out weld job, pin 7 is welded to designated position；After the completion of welding, worker is stopped operation, by
In the effect of elastic component 2, first sleeve 4 is restored to original position, and then via the first flange 11 with the whole recovery of moving electrode 1
To original position, loop back and forth like this.
As shown in Figure 3 and Figure 4, clamping piece 3 include several elastic clips 32, preferably eight, each 32 edge of elastic clip
The circumference of clamping piece 3 equidistantly distributes, and 7 uniform force of pin is made when clamping pin 7, to carry out weld job.
Preferably, the extension line of each elastic clip 32 intersects with the central axis of clamping piece 3, i.e., under each elastic clip 32
Portion is tilted to the central axis of clamping piece 3, in order to clamp pin 7；There is gap 33 between adjacent elastic clip 32, and
The gap 33 is gradually reduced from top to bottom, therefore the width of each elastic clip 32 is gradually increased from top to bottom, when pin 7 is clamped
When, the gap 33 between the lower part of each elastic clip 32, which is gradually reduced, even to abut, therefore can keep certain clamping force, will
Pin 7 is accurately positioned, to improve welding precision.
As shown in figure 4, the inner wall of each elastic clip 32 is convexly equipped with protrusion 34, when pin 7 is clamped by each elastic clip 32,
Each raised 34 lower end is abutted with pin 7, improves the positioning accuracy of pin 7；And electrode 1 will not be touched when moving downward
Each raised 34, it will not influence welding.
As depicted in figs. 1 and 2, the third that first sleeve 4 includes the first cylinder 41 and radially extends along the first cylinder 41 is convex
Edge 42, third flange 42 are abutted with the first flange 11；Second sleeve 5 includes the second cylinder 51 and radially extends along the second cylinder 51
The 4th flange 52, the 4th flange 52 abuts with the second flange 31；Elastic component 2 is spring, and one end of spring is riveted on first
Sleeve 4, the other end are riveted on second sleeve 5, for providing the power for resetting electrode 1；When worker stops welding operation,
Originally compressed spring restores to the original state, since the 4th flange 52 of second sleeve 5 is abutted with clamping element always, second set
5 positions of cylinder are constant, and spring pushes first sleeve 4 to return to original position, simultaneously because the third flange 42 of first sleeve 4 and electricity
First flange 11 of pole 1 abuts, therefore finally electrode 1 is made to be restored to original position.
Preferably, the internal diameter of spring be equal to the first cylinder 41 and the second cylinder 51 outer diameter, so as to preferably with each sleeve
Cooperation, prevents biggish shaking, while the outer wall of the first cylinder 41 and the second cylinder 51 is coated with lubricating oil, can reduce and rubs
It wipes and noise can be reduced.
Preferably, electrode 1 and clamping piece 3 are made of red metal, have good electric conductivity, are convenient for weld job.
Preferably, first sleeve 4 and second sleeve 5 are made of insulating ceramics, have good insulating properties, to prevent work
People's accidental shock.
It will be apparent to those skilled in the art that can make various other according to the above description of the technical scheme and ideas
Corresponding change and deformation, and all these changes and deformation all should belong to the protection scope of the claims in the present invention
Within.
