Background technology
When the hinge seat (processing) in existing large-scale compartment is with compartment joint welding, generally by manual line location, this mode has the following disadvantages: (1) due to compartment two lifting hinge seat apart from each other, the axiality size of the hinge hole of two lifting hinged seats is difficult to ensure; (2) after joint welding because welding deformation affects the location dimension of two lifting hinged seats; (3) manual operations, production efficiency is low, and rework rate is high, therefore causes the production cost in large-scale compartment high.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of structure simple, and productivity ratio is high and can ensure the joint welding mould that the axiality of the hinge hole of two lifting hinged seats requires.
The technical solution of the utility model is: comprise axle, latch, straight pin, positioning sleeve, nut sleeve, spring housing, bulging cover and overcoat, the external screw thread that the two ends of described axle are equipped with pin hole, spring housing installation portion and are connected with nut sleeve; Described positioning sleeve is provided with pin hole, and positioning sleeve is sleeved in axle, is connected with axle by latch; Described spring housing is sleeved in axle, is positioned at spring housing installation portion place, and in axle, inner contact position is tapered with spring housing; Described nut sleeve is arranged on external screw thread place on mandrel; Described bulging cover is sleeved in axle, is positioned at outside spring housing, tapered with spring housing outer termination synapsis; Described overcoat is enclosed within nut sleeve, is connected by straight pin with nut sleeve, and overcoat overlaps axial location to bulging.
In the joint welding jig of above-mentioned guarantee hole axiality, the spring housing installation portion of described axle is radially provided with rectangular through-hole, corresponding to the rectangular through-hole of spring housing installation portion, spring housing is also provided with rectangular through-hole.
In the joint welding jig of above-mentioned guarantee hole axiality, described latch is provided with screw thread, and screw thread place is connected with nut of pulling pin.
In the joint welding jig of above-mentioned guarantee hole axiality, the both ends of described axle are symmetrical, and the cross sectional shape of axle is circular.
In the joint welding jig of above-mentioned guarantee hole axiality, described latch is vertebra pin, matches with the tapered spigot hole arranged radial in axle, the axis of latch and the axes normal of axle.
In the joint welding jig of above-mentioned guarantee hole axiality, the cross sectional shape of described spring housing is annular.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, during welding compartment two lifting hinge seat, the utility model is located two lifting hinge seats on compartment by axle, latch and positioning sleeve, by axle, spring housing, bulging cover, nut sleeve, overcoat and straight pin, ensure the hinge hole axiality of two hinge seats, large-scale railway carriage is not only ensured in the process of being welded, and both sides hinge seat hinge hole is coaxial, location dimension, and can effective controlling distortion amount, and improve welding efficiency.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, 2, the utility model comprise axle 1, latch 2, nut 3 of pulling pin, straight pin 5, positioning sleeve 6, nut sleeve 7, spring housing 8, bulging cover 9 and overcoat 10.The cross sectional shape of axle 1 is wherein circular, the external screw thread 13 that the two ends of axle 1 are arranged with pin hole 11, spring housing installation portion 12 and are connected with nut sleeve.Described positioning sleeve 6 is sleeved in axle 1, and positioning sleeve 6 is provided with pin hole, is connected with axle 1 by latch 2.Latch 2 is taper pin, and match with the tapered spigot hole 11 arranged radial in axle 1, axes normal is in the axis of axle 1; Latch 2 is provided with the screw thread coordinated with nut 3 of pulling pin, and nut 3 of pulling pin is arranged on latch 2, for extracting latch 2 in axle.Described spring housing 8 is sleeved in axle 1, is positioned at spring housing installation portion 12 place, tapered with the inner contact position of spring housing 8 in axle 1.Described spring housing installation portion 12 place is radially provided with rectangular through-hole 14, corresponding to the rectangular through-hole 14 in axle 1, spring housing 8 is also provided with rectangular through-hole 81, during dismounting spring housing 8, available tapered wedges 4 inserts rectangular through-hole 14 and rectangular through-hole 81 intersection, relies on shearing force to be separated with axle 1 by spring housing 8.Described nut sleeve 7 is arranged on external screw thread 13 place on mandrel 1; Described bulging cover 9 is sleeved in axle 1, is positioned at the outside of spring housing 8, tapered with spring housing 8 outer termination synapsis.Described overcoat 10 is enclosed within nut sleeve 7, is connected by straight pin 5 with nut sleeve 7, and overcoat 10 pairs of bulgings overlap 9 axial location.Nut sleeve 7 is connected in aggregates with overcoat 10 by straight pin 5, both guarantees rotate synchronously in axle 1, during welding, rotating nut cover 7, overcoat 10 is made to promote bulging cover 9 extruding spreader spring cover 8, by making the external diameter swell of spring housing 8, spring housing 8 is fully contacted with the hinge hole of lifting hinge seat, thus reach the requirement of the axiality of the hinge hole of guarantee two lifting hinge seat.
