Abstract

A welding clamp suitable for butt joint of circular welds comprises a first adjusting rod and multiple groups of second adjusting rods. The second adjusting rods are evenly distributed in the radial direction of the first adjusting rod. The welding clamp is suitable for butt welding of the circular welds in different diameters and different thicknesses and can control reserved gaps accurately. The welding clamp achieves butt welding of the circular welds under the condition that only one positioner exists, can effectively avoid movement and thermal deformation of welding parts in the welding process, and is convenient to operate, rapid and efficient.

Description

A kind of weld jig that is applicable to circular weld docking
Technical field
The invention belongs to a kind of materials processing technology field, be specifically related to a kind of fixture, be applicable to the butt-welded quick blessing fixture of circular weld.
Background technology
In circular weld butt welding termination process, for thin plate, first need spot welding to fix, control preset clearance.Need bevel for middle thick plates, carry out spot welding and fix., owing to using spot welding, can there is thermal deformation in this kind of common mode of operation, cause gap size accurate not, and welder's welding gimmick is had relatively high expectations, and affected welding efficiency, and due to the existence of weld nugget, back-welding shape is attractive in appearance not.
Summary of the invention
The object of the invention is to, a kind of quick blessing instrument for circular weld is provided, be applicable to the circular weld docking welding of different-diameter different-thickness, and can control accurately preset clearance.Realize only having a circular weld docking welding in positioner situation, can effectively prevent movement and the thermal deformation of weldment in welding process, easy to operate, rapidly and efficiently.
A weld jig that is applicable to circular weld docking, comprises the first adjusting rod, some groups of the second adjusting rods, every group of second adjusting rod being radially uniformly distributed along the first adjusting rod.
Preferably, described the second adjusting rod is radially uniformly distributed along the first adjusting rod two ends or middle part.
Further, the bar that described the first adjusting rod comprises sleeve and matches with sleeve, in order to adjust the distance at the first adjusting rod two ends.And then adjust workpiece and reserve spacing.
Further, the sleeve of described the first adjusting rod is connected by engage thread with the bar matching with sleeve.
Further, the adjusting screw thread that described the second adjusting rod comprises support bar and rotates in support bar, the distance between support bar and the first adjusting rod is by regulating threaded adjusting.
Further, the free end of described support bar is provided with cushion block.
Further, between described support bar and cushion block, be provided with free ball.Be connected with support bar by ball, can mate with workpiece radian preferably.
Preferably, describedly have 6 along the first radially equally distributed the second adjusting rod in adjusting rod two ends.
Preferred, describedly have 6 along the first radially equally distributed the second adjusting rod in adjusting rod two ends, the quantity of every end the second adjusting rod is 3.
The present invention is applicable to the circular weld docking welding of different-diameter different-thickness, and can control accurately preset clearance.The present invention is by two pairs of support bars, and the connection of screw rod, can realize in the accurate docking of only having circular weld workpiece in a positioner situation, adjusts preset clearance.And do not need spot welding to fix, simple in structure, easy to operate, improve welding efficiency.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is one end of the present invention stationary annular workpiece schematic diagram;
Fig. 3 is stationary annular workpiece schematic diagram of the present invention.
Detailed description of the invention
As shown in Figure 1, a kind of weld jig that is applicable to circular weld docking, comprises the first adjusting rod, some groups of the second adjusting rods, every group of second adjusting rod being radially uniformly distributed along the first adjusting rod.The second adjusting rod can be at the two ends of the first adjusting rod or middle part be radially uniformly distributed along the first adjusting rod.In the present embodiment, be provided with two group of second adjusting rod at the two ends of the first adjusting rod, every group of second adjusting rod is 3, has respectively 3 the second adjusting rods to be located at the first adjusting rod two ends being radially uniformly distributed along the first adjusting rod.
The first adjusting rod comprises with female sleeve 5 and the bar 4 that matches with sleeve, bar 4 is connected by engage thread with sleeve 5, make the bar 4 can be in the interior rotation of sleeve 5, bar 4 can be adjusted the distance between the second adjusting rod that is distributed in the first adjusting rod two ends in the rotation of sleeve 5, and then adjusts the reserved spacing between circular weld.
The second adjusting rod comprises support bar 1 and the adjusting screw thread 2 in support bar 1 interior rotation.Sleeve 5 one end are connected with bar 4 one end, the other end of sleeve 5 other ends and bar 4 is connected with and regulates screw thread 2 as the two ends of the first adjusting rod respectively, regulate screw thread 2 to be connected in support bar 1, and can be in the interior rotation of support bar 1, by regulating the rotation of screw thread 2, can regulate the distance between support bar 1 and the first adjusting rod, further can control the support force to annular workpieces 6.Support bar 1 free end is also with cushion block 3, and cushion block 3 is connected with support bar 1 by ball (not shown), can mate with workpiece radian preferably.
As shown in Figure 2,3, annular workpieces 6 is supported by the support bar 1 of a side, and by regulating screw thread 2 workpiece pressings, the support bar 1 of opposite side is adopted to use the same method and compressed annular workpieces 6.Then by regulating screw thread 4 to adjust the reserved spacing between two annular workpieces 6, can realize in the accurate docking of only having circular weld workpiece in a positioner situation, adjust preset clearance; And do not need spot welding to fix, simple in structure, easy to operate, improve welding efficiency.
