Preferably, the telescopic rod includes lower support bar, the second cylinder and upper support bar, installation at the top of the lower support bar
There is the second cylinder, upper support bar is installed on the piston rod of second cylinder.
Preferably, it is equipped with threaded hole among the sliding block, the threaded rod is set in threaded hole, and the sliding block two sides are equal
Equipped with slide opening, two slide bars are respectively sleeved in two slide openings.
Preferably, the clamping device includes L shape support frame, third cylinder and gripping block, peace at the top of the L shape support frame
Equipped with third cylinder, gripping block is installed on the piston rod of the third cylinder.
Preferably, the gas source is carbon dioxide or argon gas.
Compared with prior art, the invention has the following beneficial effects: can be by harvesting machine part clamping by clamping device
On the table, threaded rod can be driven to rotate by motor, threaded rod rotation can be axially moved with movable slider, to drive welding gun
It is axially moved, is realized radial through telescopic rod is flexible, the spot welding work of harvesting machine part can be realized, gas is set on welding gun head
Body protective cover, venthole are distributed in weld seam i.e. in cover bottom, the inert gases such as the argon gas or carbon dioxide that are released by it
Its edge prevents weld seam and its edge from being aoxidized and blackening, to improve weld appearance and quality.

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Fig. 1-4 is please referred to, the present invention provides technical solution;Machine part processing gas-shielded welding device is gathered in, including
Pedestal 1, the 1 top two sides of pedestal are mounted on telescopic rod 2, are mounted on fixed block 3 at the top of two telescopic rods 2, and two
Threaded rod 5 is equipped with by bearing 4 between a fixed block 3,5 upside of threaded rod is mounted on slide bar 6, institute with downside
