Description

One kind is welded and fixed frock

Technical field

This utility model is related to one kind and is welded and fixed frock, particularly welds together 2 parts it is ensured that corresponding size The one kind requiring is welded and fixed frock.

Background technology

Size after part welding needs processing and surplus is larger, and such part is relatively low to the dimensional requirement of postwelding, no Need corresponding fixing tool just can process it is only necessary to ensure size substantially, then to distribute according to corresponding size plus Spare time measures, and such part does not often need to load onto corresponding fixing tool in welding, after the precision of part is by welding Processing ensure.And in a special case, part after welding, due to size and shape restriction be unable to reworking, This brings certain difficulty just to the guarantee of the dimensional accuracy of postwelding, so when welding this part, needing reasonable in design Frock, in order to ensure that the accessory size after welding and precision meet the requirement of designer.And the design of frock need to consider should Meet the convenience of clamping, ensure that tool structure is simple again, conveniently install and dismantle.During use, frock and part need to be loaded onto Parallel folder, and to certain coupling mechanism force, to ensure part in welding process, because of welding stress, and with frock, phase will not occur To the changing of the relative positions.So 2 parts are welded together, and need to ensure corresponding size requirement problem particularly typical.

Content of the invention

In order to solve to weld together 2 parts, and the problem of corresponding size requirement need to be ensured, this utility model provides One kind is welded and fixed frock.

This be welded and fixed frock it is characterised in that including fixing tool main body, limited block and parallel folder, use interior hexagonal Part to be welded is locked in fixing tool main body fillister head screw assembly a, then will be fixed with hexagon socket cap head screw assembly b Frock main body is locked in part main body, finally with limited block, part main body and fixing tool main body is carried out radially spacing, uses Parallel folder carries out axial limiting to part main body and fixing tool main body.The inner mold of fixing tool main body is rounded face, with part Main body is cylindrical accordingly quite, and external form is to be made up of with two projections rounded face, and this two raise into 180 ° of distributions, similar to armful Hoop, there are 5 circular boss in face at one end, and wherein 3 boss are less and equally high, and another 2 boss are relatively large and equally high, One circular concave step and 4 uniform screwed holes are all had on this 2 larger boss, in fixing tool main body There are 2 square breach in chamber, and is one-to-one with 2 larger boss on end face, this part along in external form two projections and The position crossing the center of circle is divided into two parts；Limited block is regular hexahedron.

Hexagon socket cap head screw assembly a is made up of hexagon socket cap head screw a, flat shim a, spring washer piece a, hexagonal cylindrical Head screw assembly b is made up of hexagon socket cap head screw b, flat shim b, spring washer piece b and nut b.

This utility model use when, by fixing tool main body together with parts assembly to be welded, on part flange to be welded Male half coupling load the corresponding position of larger boss on fixing tool main body end face, load onto hexagon socket cap head screw assembly a, twist Tightly, then by fixing tool main body it is assembled together with part main body, after relative position determines, load onto interior hexagonal cylindrical head spiral shell Screw assembly b, tightens, and corresponding position is loaded onto limited block and carried out radially spacing, finally loads onto parallel folder, gives necessarily to lock Power, carries out axial limiting, fixing tool main body and part to be welded and fixing tool main body to part main body and fixing tool main body After the face contacting with part main body is adjacent to completely, and part to be welded correct with the position of part main body after can be welded. After the completion of welding, frock of dismantling, carry out the welding of next part.

This utility model is reusable, good reliability, and accuracy is high；And it is simple and reasonable, when there is reuse High precision, saves production cost it is adaptable to weld together 2 parts, and can guarantee that corresponding size requirement.
