Do-it-yourself magnetic clamp for welding
Hello, dear readers and DIY!
When performing welding work, sometimes you need to weld small parts to the surface, for which you need to fix them.
In this article, the author of the YouTube channel “Be Creative” will tell you how he made a special clamp with magnetic base.
This the project is very easy to manufacture, but it will require a small amount of welding.
Materials needed for DIY.
– Screws, washers, nuts
– Set of springs
– Plastic pipe plugs with M8 nut
– Rectangular neodymium magnet with holes
– Magnet from an old speaker
– Steel profile tube, strip, bar.

Tools used by the author.
– Screwdriver, drills for metal
– Grinder, cutting disc, flap stripping
– Semi-automatic core, pliers
– Tap holder with ratchet mechanism, tap
– Geifer gripper, vice
– Welding machine, welding wire
– Svenson's square, tape measure, marker.
Manufacturing process.
So, as a stand the author uses square steel profile pipe.
Cutting off the workpiece with a length of about 200 mm, the author steps back from the edge of 15 mm, cores the center, and drills a through hole with a diameter of 8 mm. An axis will pass through this hole.

The tops of the other two walls are removed and eyelets are formed.

К a small nut or ring is welded to the lower front of the rack. A spring will cling to it.
A piece of steel strip is tried on to the bottom end of the post and a cap is cut out of it.
the plug with a geyfer grip, in its center the master drills a hole with a diameter of 8 mm.
An m8 bolt is inserted into the hole, and its head is welded to the plug. The threaded part of the bolt must be perpendicular to the plane of the plug, for which, before welding, these parts are fixed in a vice.

Now the plug is welded to the rack so that the threaded part of the bolt is outside.
Of course, you can solve this problem without using welding by installing just such a furniture plastic plug with an m8 nut.

A round steel pipe will serve as a lever. An 8mm axle hole is drilled near one end.
The m8 nut is screwed onto the screw, the threaded part of the screw is fixed in the screwdriver chuck, and the edges of the nut are grinded using a grinder with a petal disc.
The outer diameter of the nut must be such that it fits snugly into the arm tube. Pressing the nut on the side of the lever where the hole has not been drilled yet, the author welds it to the pipe.
Here you can also do without welding by installing a ready-made plastic plug for pipes with an m8 nut.
Having turned the pipe 90 degrees relative to the axis of the first hole, two holes are drilled with a thin drill to hold the spring.
More one 6mm hole is made near the nut. A pressure pin will be inserted through it.
A 6mm steel bar is suitable for clamping. A master cuts a 180 mm long billet from a bar.
Fixing a bar in a screwdriver chuck, its end is sharpened using the same grinder.
To hold the entire structure on a metal surface, you need a magnet from the old speaker.
It needs to be separated so that the magnetic cores remain in place.
Of course, you can use a pair of modern neodymium magnets instead.
A hole is drilled in the center of the magnetic circuit, from its back side, and a thread m8 is cut in it.
The depth of the hole must be greater than the length of the bolt welded to the post.
The screw is screwed into the prepared hole, and the main part of the structure is assembled.
Eyelet tension springs cling to the lever.

The lever is inserted between the lugs, and is connected to the strut with an m8 bolt. The latter will serve as an axis. Of course, it wouldn't hurt to install a bushing here.

The second end of the spring catches on the nut welded to the rack.

The last pin is inserted into the hole in the lever and fixed with a bolt.

Here the author got such a clamping device.
< a href = "https://usamodelkina.ru/uploads/posts/2021-02/1613903527_mpr-153.jpg" rel = "prettyPhoto">
To demonstrate its capabilities, the author presses a couple of nuts to the surface of the welding table and grabs them together welding.
< a href = "https://usamodelkina.ru/uploads/posts/2021-02/1613903528_mpr-160.jpg" rel = "prettyPhoto">
The main purpose of this device is to press a bolt or nut to a metal surface and hold it during welding .
This clamp came out very large, and for greater ease of use, its size can be reduced. < br>
I thank the author for a simple but useful device for welding.
Everyone good mood, good health, and interesting ideas!
