During welding, gear ring (Q) is sleeved on gear (C) top, this gear set is in the path section (1a) of welding supporting seat (1), fit in the bottom surface of gear (C) and the upper surface of central diameter section (1b), and the projection of gear (C) bottom edge snaps in the centralized positioning groove (2a) on lower location-plate (2), and fit in the centralized positioning boss (3a) of upper location-plate (3) and gear ring (Q) upper surface, finally by least two compact heaps (4), lower location-plate (2) and upper location-plate (3) are compressed.
Adopt above technical scheme, gear (C) is had good positioning by lower location-plate (2) by the utility model, and by upper location-plate (3) and lower location-plate (2), gear (C) and gear ring (Q) are clamped, thrust is large, obvious distortion is there is because of being heated when so just can effectively avoid gear ring (Q) to weld, thus guarantee welding quality, ensure the qualification rate of product, and this apparatus for welding and positioning structure is simple, easy to use, there is good practicality.
Described lower location-plate (2) is circumferentially evenly equipped with 2 n shape grooves (2b), this n shape groove opens the edge in lower location-plate (2).Adopt above structure, described n shape groove (2b) can be fixed with two of a fixed platform locating dowel, thus is convenient to the fixing lower location-plate (2) when clamping gear (C) and gear ring (Q).
As preferably, the upper and lower hold-down segment of described compact heap (4) is tilting section, and its angle of inclination is 15 °-30 °, and unsettled section of these two hold-down segment in opposite directions, be so both convenient to dismounting compact heap, can ensure that again thrust is enough large.
Beneficial effect: gear is had good positioning by lower location-plate by the utility model, and by upper location-plate and lower location-plate, gear and gear ring are clamped, thrust is large, reliable, compressing and unclamp all more convenient, when so just can effectively avoid gear ring to weld, because of being heated, obvious distortion occurring, thus ensureing welding quality, ensure the qualification rate of product, and this apparatus for welding and positioning structure is simple, easy to use, there is good practicality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the schematic diagram of lower location-plate in Fig. 1.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 1, 2, a kind of apparatus for welding and positioning, is formed primarily of welding supporting seat 1, lower location-plate 2, upper location-plate 3 and compact heap 4.Wherein, welding supporting seat 1 is syllogic multidiameter structure, is followed successively by path section 1a, central diameter section 1b and large footpath section 1c from top to bottom.Described lower location-plate 2 is sleeved on welding supporting seat 1, and fit in the lower face of this lower location-plate 2 and the upper surface of large footpath section 1c, and the upper face of lower location-plate 2 is provided with a centralized positioning groove 2a.Described lower location-plate 2 is circumferentially evenly equipped with 2 n shape groove 2b, this n shape groove is opened at the edge of lower location-plate 2.Be provided with one piece of upper location-plate 3 directly over described lower location-plate 2, on this, location-plate 3 has centre bore, and the lower face of upper location-plate 3 is provided with centralized positioning boss 3a.Described compact heap 4 is made up of vertical linkage section, upper hold-down segment and lower hold-down segment, and upper hold-down segment is connected with the corresponding end of vertical linkage section with one end of lower hold-down segment, and the other end of these two hold-down segment is all unsettled.Upper hold-down segment and the lower hold-down segment of described compact heap 4 are tilting section, and its angle of inclination is 15 °-30 °, and unsettled section of these two hold-down segment in opposite directions.
