Abstract

The utility model discloses a fit-up fixture used for manufacturing pipelines. The fixture comprises a U-shaped rod, a screw, a handle, a link block, a hook, a cushion block and a suspension link. A tapped hole is formed in the center of the U-shaped rod, the screw is positioned in the screw, a through hole is formed at one end of the screw and positioned perpendicular to the axial direction of the screw, the handle is positioned in the through hole, the link block is arranged at the other end of the screw, the screw can freely rotate in the link block; the hook is fixed on the other surface of the link block; one end of the suspension link is sleeved at the center of the cushion block; and the other end thereof is suspended on the hook. The utility model utilizes the U-shaped rod and the screw to form a pull rod which is arranged on the outer surface of a nozzle of a pipeline, the cushion block is arranged on the inner surface of the nozzle of the pipeline, the suspension link on the cushion block is suspended in the hook at one end of the screw; the handled at one end of the screw is rotated to align the nozzle of the pipeline so as to conduct the installation of the butt joint of pipelines. No other auxiliary tools are welded on the surface of the pipelines when the fixture is used, so as to improve the quality of the pipeline and efficiency of manufacturing the pipeline, and save labor, time and materials for butting the pipelines.

Description

The group that pipeline is made is to jig

Technical field

The utility model relates to group in a kind of pipeline manufacturing process to jig.

Background technology

In the manufacturing process of pipeline mouth of pipe butt joint, because a variety of causes may cause the mismatch of the pipeline mouth of pipe, at mouth of pipe mismatch, usually adopt chock, homemade instruments such as angle steel card carry out welding assembly after the mouth of pipe is alignd, adopt above-mentioned instrument at first must assist jig in the pipe surface welding, use instrument such as chock to make mouth of pipe alignment then, but the jig of pipe surface welding is removed after pipeline butt joint assembling is finished at once, leave crator at pipe surface thus, therefore destroy the quality of pipe surface, needed the crator of pipe surface polished and wait processing, then increased the operation of pipeline installation, reduce efficient, expended labor and materials.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of group of pipeline making to jig, it does not need at the auxiliary jig of pipe surface welding, utilize this jig can realize the alignment of mouth of pipe mismatch, the group that realizes the pipeline making is to operation, improve quality and efficient that pipeline is made, saved the material in man-hour that pipeline is made.

For solving the problems of the technologies described above, the group that the utility model pipeline is made comprises the U-shaped bar to jig, screw mandrel, contiguous block, handle, cushion block, hook and draw ring, described U-shaped bar center has screw, described screw mandrel is positioned at described screw, described screw mandrel one end down-feed screw axially has through hole, described handle is positioned at described through hole, described contiguous block simultaneously has groove, the described screw mandrel other end is located in the groove of described contiguous block and screw mandrel is rotated in described groove, the fixedly connected described hook of described contiguous block another side, described draw ring is hung on the described hook after being placed in described cushion block.

Be the surfaces externally and internally of protection pipeline, above-mentioned U-shaped bar two free-ended cross sections are greater than the cross section of described U-shaped bar, and described U-shaped bar two free ends are butted on pipeline external surface, and the cross section of described cushion block is trapezoidal, and described trapezoidal minor face is butted on side opposite; Described draw ring is that steel band is made.

Because the group that the utility model pipeline is made has adopted technique scheme to jig, promptly utilize U-shaped bar and screw mandrel to form the outer surface that pull bar is located at the pipeline mouth of pipe, cushion block is located at the inner surface of the pipeline mouth of pipe, draw ring is buckled on the hook of contiguous block of screw mandrel one end, the draw ring other end is placed in the cushion block center, the handle of turn screw mandrel one end then, is transferred the pipeline mouth of pipe together to carry out the location welding of pipeline butt joint to the pulling force and the thrust of tube wall by cushion block and U-shaped bar two free ends; Utilize this jig not need to weld any auxiliary jig, improved quality and efficient that pipeline is made, saved the material in man-hour that pipeline is made at pipe surface.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and embodiments:

The group that Fig. 1 makes for the utility model pipeline is to the structure and the work schematic diagram of jig.

The specific embodiment

As shown in Figure 1, the group that pipeline is made comprises U-shaped bar 1 to jig, screw mandrel 2, contiguous block 4, handle 3, cushion block 6, hook 5 and draw ring 8, described U-shaped bar 1 center has screw, described screw mandrel 2 is positioned at described screw, described screw mandrel 2 one end down-feed screws 2 axially have through hole, described handle 3 is positioned at described through hole, described contiguous block 4 one sides have groove, described screw mandrel 2 other ends are located in the groove of described contiguous block 4 and screw mandrel 2 are rotated in described groove, the fixedly connected described hook 5 of described contiguous block 4 another sides, described draw ring 8 is hung on the described hook 5 after being placed in described cushion block 6.

Be the surfaces externally and internally of protection pipeline 7,1 liang of free-ended cross section of described U-shaped bar is greater than the cross section of described U-shaped bar 1, and 1 liang of free end of described U-shaped bar is butted on pipeline 7 outer surfaces; The cross section of described cushion block 6 is trapezoidal, and described trapezoidal minor face is butted on the inner surface of pipeline 7; Described draw ring 8 is that 2 millimeters steel band 2mm make, and to guarantee the pipe joint group gap is adhered to specification.

This group utilizes U-shaped bar 1 and screw mandrel 2 to form the outer surface that pull bar is located at pipeline 7 mouths of pipe to jig, cushion block 6 is located at the inner surface of pipeline 7 mouths of pipe, draw ring 8 is buckled on the hook 5 of contiguous block 4 of screw mandrel 2 one ends, draw ring 8 other ends are placed in cushion block 6 centers, the handle 3 of turn screw mandrel 2 one ends then, by cushion block 6 and 1 liang of free end of U-shaped bar pulling force and thrust, pipeline 7 mouths of pipe are transferred together to carry out the location welding of pipeline 7 butt joints tube wall; Utilize this jig not need to weld any auxiliary jig, improved quality and efficient that pipeline is made, saved the material in man-hour that pipeline is made at pipe surface.
