Background technology
Pin sleeve is a kind of common mechanical structure, and in order to ensure size and positional precision, the positioning welding of pin sleeve must
It must be carried out by frock.At present, most common pin sleeve positioner is mandrel rod, can ensure pin sleeve position dimension and
Axiality requirement.But due to pin sleeve welding deformation, it is difficult to remove that can cause mandrel rod postwelding, so, normally only in spot welding
When use, it is impossible to welding when use.
The content of the invention
, can the invention overcomes the deficiencies of the prior art, and provides a kind of pin sleeve positioning welding process unit
Meet the spot welding and welding requirements of pin sleeve simultaneously.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is：Pin sleeve positioning welding process unit, bag
Locating shaft and adjusting screw rod are included, the positioning section of the locating shaft is in hollow-core construction, and is provided with internal thread in the hollow-core construction, institute
State in the insertion hollow-core construction of the adjusting screw rod by external screw thread matching thereon, be provided with the side wall of the hollow-core construction
Multiple square positioning through hole, the interior matching of the positioning through hole are fitted with tensioning block, and the outer end of the tensioning block is used for tight lifting pin
Shaft sleeve workpiece, the inner of the tensioning block are inclined plane, and the inclined plane and the push rod slopes which match in hollow-core construction,
Moved by the mobile promotion tensioning block of push rod in positioning through hole, realize the clamping and release of pin sleeve workpiece, the push rod
One end and adjusting screw rod ends contact, the other end of the push rod is provided with back-moving spring.
Multiple positioning through hole circumferentially array distribution in hollow-core construction.
It is in hollow-core construction that the locating shaft is overall, and the both ends of the locating shaft are provided with adjusting screw rod, the regulation
The end of screw rod is provided with push rod, and back-moving spring is provided between two push rods, and each push rod corresponds to one group of tensioning
Block, for holding out against each self-corresponding pin sleeve workpiece.
The present invention has an advantageous effect in that compared with prior art：The present invention can be good at improving pin sleeve because weldering
The shortcomings that connecing deformation and being difficult to remove positioning tool, the dimensional accuracy of spot-welded is significantly improved, improve production efficiency.
Brief description of the drawings
The present invention is described further below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the present invention.
In figure：1 it is locating shaft, 2 be adjusting screw rod, 3 be positioning through hole, 4 be tensioning block, 5 be pin sleeve workpiece, 6 is multiple
Position spring, 7 are push rod.
Embodiment
As shown in figure 1, inventive pin axle sleeve positioning welding process unit, including locating shaft 1 and adjusting screw rod 2, it is described fixed
The positioning section of position axle 1 be in hollow-core construction, and internal thread is provided with the hollow-core construction, the adjusting screw rod 2 by thereon outside
In the insertion hollow-core construction of screw thread matching, multiple square positioning through hole 3, institute are provided with the side wall of the hollow-core construction
State matching in positioning through hole 3 and be fitted with tensioning block 4, the outer end of the tensioning block 4 is used for tight lifting pin shaft sleeve workpiece 5, the tensioning
The inner of block 4 is inclined plane, and the inclined plane and the slopes which match of push rod 7 in hollow-core construction, passes through the movement of push rod 7
Promote tensioning block 4 to be moved in positioning through hole 3, realize the clamping and release of pin sleeve workpiece 5, one end of the push rod 7 and tune
The ends contact of screw rod 2 is saved, the other end of the push rod 7 is provided with back-moving spring 6.
Multiple positioning through hole 3 circumferentially array distribution in hollow-core construction.
The overall locating shaft 1 is in hollow-core construction, and the both ends of the locating shaft 1 are provided with adjusting screw rod 2, the tune
The end of section screw rod 2 is provided with push rod 7, and back-moving spring 6, each push rod 7 corresponding one are provided between two push rods 7
Group tensioning block 4, for holding out against each self-corresponding pin sleeve workpiece 5.
The course of work of the present invention：Adjusting screw rod 2 can be opened by its screw-in depth in locating shaft 1 of threaded adjustment
Tight block 4 is close to the batter post face of push rod 7, and is limited in the positioning through hole 3 of locating shaft 1.During stretching, by adjusting screw rod 2 from
The inward at both ends of locating shaft 1 screws in, and heads on the slid inward of push rod 7 of both sides, tensioning block 4 is under the promotion of push rod 7 along locating shaft 1
Positioning through hole 3 is slided to outside locating shaft 1, and pin sleeve workpiece 5 at two is held out against, and realizes that the positioning of pin sleeve workpiece 5 clamps.Unclamp
