Summary of the invention
The object of the invention is to, provide a kind of welding positioning tool, angle bar firmly can be fixed, need not continue force after angle bar is fixing, frock also can continue fixing angle bar.
The present invention is achieved through the following technical solutions:
A kind of welding positioning tool, comprise base plate, the first side plate, the second side plate, two clamping devices and two backstays, first side plate and the second side plate are fixed on base plate, first side plate and the second side plate are perpendicular to base plate, first side plate is perpendicular to the second side plate, clamping device comprises universal joint, the bar that is connected, supporting rod and handle, one end of universal joint is fixed on base plate, the other end connects the one end of the bar that is connected, the other end of bar of being connected is provided with handle, be connected on bar and be provided with supporting rod, the making material of supporting rod is elastomeric material, and backstay is fixed on base plate.Welding positioning tool of the present invention is used for fixing two angle bar, and the angle bar be fixed is mutually vertical, even and if fixing after need not hand steered frock, frock also can continue firmly to fix angle bar.After angle bar is well placed, a sidewall of angle bar is close to the first side plate or the second side plate, then supporting rod is made to clamp angle bar by control handle, because supporting rod is resilient, therefore supporting rod can produce certain deformation, and then continue control handle and move, the bar that makes to be connected is blocked by backstay, the bar that makes to be connected can not move, and has also just been fixed by angle bar.
In aforesaid welding positioning tool, supporting rod comprises the first housing, spring and convex position, and the first shell one end is fixedly connected with the bar that is connected, and spring is fixed in the first housing, and convex position is arranged on the other end of the first housing, and convex position is connected with spring.By arranging spring, supporting rod can be made deformation can to occur, also blocking by backstay when making clamping device clamp angle bar.
In aforesaid welding positioning tool, convex position is cylindric, and the making material of convex position is rubber.Elastomeric material inherently can by the certain deformation of stressed generation, and the hardness of rubber is not high, can not cause cut on angle bar.
In aforesaid welding positioning tool, the bar that is connected is provided with at least two supporting rods, and the first housing is tubular, and the first housing is perpendicular with the bar that is connected.
In aforesaid welding positioning tool, backstay is vertically set on base plate, and backstay is in " T " font.The backstay of " T " font bar that can prevent from being connected departs from the restriction of backstay.
In aforesaid welding positioning tool, the first side plate perpendicular to the second side plate, the first side plate and the second side plate non-intersect.That is have a breach between the first side plate and the second side plate, this breach is for being come out by angle bar, convenient welding, for welding angle bar provides sufficient space.
Compared with prior art, welding positioning tool of the present invention, can fix two angle bar firmly, two angle bar are mutually vertical, need not continue after angle bar is fixing frock force, frock also because of elastic force motion in the other direction, still can not can clamp angle bar firmly.And motion flexibly, can be saved time, fix angle bar rapidly.
