Metal-top welding table

Abstract

A welding table used in welding industry and woodworking applications comprises a metal table top with retractable carrying handle and elongated slots for insertion of clamping tools, a protrusion-adjustable angle flange with V-notch mounted to at least one edge of the table top, a support structure having an angle and height adjusting mechanism, and a foldable base frame with casters.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a class of portable workbench in general, and particularly to a metal-top welding table used in welding industry and woodworking applications. The present invention comprises a metal table top with retractable carrying handle and elongated slots for insertion of clamping tools, a protrusion-adjustable angle flange with V-notch mounted to at least one edge of the table top, a support structure having an angle and height adjusting mechanism, and a foldable base frame with casters.[0003]2. Description of the Related Art[0004]A portable workbench used in welding industry and woodworking applications typically comprises a flat table top with a number of round holes for inserting clamping tools. The flat table top is either made of plastic material to reduce the weight for portability in the expense of strength and rigidity or made of heavy solid metal plates for rigidity but too heavy for por...

AI Technical Summary

Benefits of technology

[0006]The rectangular flat table top is made of sheet metal for rigidity without adding too much weight to the present invention. The four edges of the table top are bent downward to form four fold-down edges. At proper location of the flat table top, a plurality of elongated slots are equipped for the insertion of clamping tools. Elongated slots accepts clamping tools with cylindrical shanks as well as most other types of clamping tools, say C-clamps, bar clamps, etc. This will increase the flexibility and convenience of the present invention. The straight edge of each elongated slot is bent downward to a proper depth to increase the strength of the table top and to create a thickness of the table top for clamping tool usage.

[0007]At least one fold-down edge of the table top is made with two or more screw holes for the mounting of the angle flange. The angle flange is equipped with two or more elongated holes on one side for mounting to one of the fold-down edge of the table top with wing screws. The angle flange is equipped with one or more elongated slots on the other side for the mounting of additional clamping tool if necessary. The position of the angle flange relative to the table top is adjustable so that the upper edge of the angle flange is below the table top or protrude above the table top. The amount of protrusion is variable utilizing the elongated holes on the angle flange and the wing screws. When the upper edge of the angle flange protrudes above the table top, workpiece can be held against the angle flange by clamping tool. When adjacent fold-down edges of the table top are equipped with angle flanges, then the two protruded adjacent angle flanges form a right angle guide rail to align two workpieces at 90 degree spatial relationship easily. At least one V-notch is formed on the upper edge of the angle flange to hold cylindrical or bar shape workpiece firmly and easily on the table top. This feature adds more flexibility to the present invention.

[0009]The foldable base frame consists of two sets of U-shape frames and two square tubes with triangular plates. The internal size of each square tube is big enough so that the straight shank of the support structure can be inserted and slidable inside the square tube. Holes are made on two opposite sides of the square tubes for inserting pins to adjust and fix the height of the table top. One set of the U-shape frame is pivoted to one corner of the triangular plates and the other set of the U-shape frame is pivoted to the other corner of the triangular plates. Hence the U-shape frames are pulled open to form a sturdy stand for the table top and pushed close for easy storage and portability. Two casters are fixed to one set of the U-shape frames for easy transportation of the present invention. To enhance the easy handling of the present invention, a retractable handle is equipped on one fold-down edge of the table top. With this retractable handle, the present invention can be carried or pulled on casters with one hand.

Problems solved by technology

Some prior arts equipped with flanges to hold the workpiece but the flanges are not adjustable.
