In a kind of specific embodiment of the provided flange fixture head of this utility model, including air chamber 5, locating piece 4 and latch 3.Air chamber 5 is a hollow cavity, and for being filled with shielding gas, the cavity can be by latch 3, locating piece 4 and weld bag Wrap up in, to carry out gas shield to the flange head 2 in welding process or welding cooling procedure and body 1, the top of air chamber 5 sets There are opening, locating piece 4 to be fixedly installed in the inner bottom wall of air chamber 5, flange head 2 is put in air chamber 5 via the opening on air chamber 5, Locating piece 4 can be used for positioning of the realization to flange head 2 in air chamber 5, can specifically pass through the roof and flange head of locating piece 4 The wall configuration for contacting locating piece 4 on 2 is adapted to realize, or realizes that locating piece 4 can be with root by arranging the structures such as groove It is designed according to being actually needed.Latch 3 be used for and locating piece 4 coordinate clamping flange head 2, be provided with the side wall of air chamber 5 for Grafting the spacing hole of Fixed latches 3, a latch 3 are correspondingly plugged in two spacing holes, and spacing hole runs through the side wall, latch 3 from the outside of air chamber 5 through the inside of a spacing hole insertion air chamber 5, and can pass from another spacing hole with fixed slotting Pin 3, the part that latch 3 is placed in inside air chamber 5 coordinate clamping flange head 2 with locating piece 4 from upper and lower both sides, meanwhile, latch 3 is inserted After spacing hole, spacing hole can be carried out to latch 3 spacing and be fixed, and prevent latch 3 to be moved upwardly by.

In a kind of specific mode of operation, positioning is carried out to flange head 2 by locating piece 4 and is rested against, make 3 supported flange of latch 2, after welding cooling, latch 3 can be gone out with punching pin or miscellaneous part, to obtain weldment.

It can be seen that, this kind of flange fixture head is by the cooperation between latch 3 and locating piece 4 and latch 3 and spacing hole, clamping Area is larger, can bear larger deformation force, can more reliablely and stablely clamp flange head 2, effectively prevents body 1 from becoming Shape, welding effect is good and high precision, can conveniently realize dismounting in the case where bearing more energetically, simple to operation, can Reduce and the interference between welding gun, and simple and stable structure, taking up room relatively small, cost of manufacture is relatively low, and the suitability is preferable, Use condition can not be limited by flange head 2.

In above-described embodiment, latch 3 can be coordinated with gap with spacing hole.That is, the aperture of spacing hole can be more than The aperture of latch 3, such that it is able to be filled with shielding gas by spacing hole come interior to air chamber 5, setting is simple and convenient, advantageously reduces gas Hole machined on room 5.It is of course also possible to realize the behaviour for being filled with shielding gas by being separately provided passage or other modes Make.Wherein, when latch 3 clamps flange head 2 in spacing hole is installed on, should ensure that the top of latch 3 is subject to the spacing of spacing hole Effect, so that ensure thrust of the latch 3 to flange head 2.

In each embodiment above-mentioned, the roof of latch 3 can be obliquely installed relative to the pressure part surface of 3 bottom of latch, i.e., Tilt Datum Plane face of the pressure part surface for 3 roof of latch, and inclination angle is towards one end of latch 3.Wherein, the end of latch 3 refers to It is two ends of the latch 3 when spacing hole is inserted in direction of insertion, the inclination angle of latch 3 shows latch towards one end of latch 3 3 roof is inclined towards the other end by one end of latch 3, from the point of view of the longitudinal section by latch 3, along direction of insertion, the one of latch 3 Hold as bigger diameter end, the other end is miner diameter end.When latch 3 inserts spacing hole, at least one spacing hole has to the top of latch 3 Position-limiting action.The roof of latch 3 is set to the wall with gradient, 3 insertion depth of regulating pin latch 3 in other words can be passed through Part surface and 4 distance of locating piece are pressed to adjust in stop place in spacing hole, it is ensured that pressure part surface can be with compressing component.When So, the roof of latch 3 can also be arranged in parallel with pressure part surface or carry out other settings.

Specifically, the roof of latch 3 may range from 1 relative to the gradient of pressure part surface:52 to 1:48, to ensure While latch 3 has the regulatory function in above-described embodiment, the position-limiting action to latch 3 of spacing hole is ensure that.It is preferred that Ground, the roof of latch 3 can be 1 relative to the gradient of pressure part surface:50, it is easy to process.Certainly, the setting of gradient is not limited In this.

In each embodiment above-mentioned, the longitudinal section of latch 3 can be L-shaped, and folded walls are located at the bottom of the latch 3, That is the diapire of latch 3 is in step-like, and wherein, the bottom of latch 3 includes above-mentioned pressure part surface, in the present embodiment, the bottom of latch 3 Also include in portion that the wall adjacent with pressure part surface, pressure part surface can clamp flange head 2 in the vertical with locating piece 4, meanwhile, Wall can carry out horizontal spacing to flange head 2, so that latch 3 can make full use of the space in air chamber 5, increase latch Thickness on 3 Impact direction and longitudinal direction, improves the holding capability to flange head 2, strengthens the bending strength of latch 3, and is easy to Dismounting.Certainly, the longitudinal section of latch 3 can be rectangle, trapezoidal or other shapes.

Preferably, the edge of pressure part surface can also arrange chamfering, to reduce the abrasion between latch 3 and flange head 2.

In each embodiment above-mentioned, the quantity of latch 3 can be two.Two latches 3 are limited to flange head 2 simultaneously Position, spacing stable.Wherein, there are four spacing holes, each two spacing hole one latch 3 of corresponding grafting on air chamber 5.Specifically, two Individual latch 3 can be arranged in parallel, in order to process.Certainly, the quantity of latch 3 is arranged and is not limited to two.

In each embodiment above-mentioned, spacing hole is specifically as follows rectangular opening, in order to process.Specifically, spacing hole can be with For square hole, processing is further facilitated.

In each embodiment above-mentioned, locating piece 4 can specifically be connected by screw, weld etc., and mode is fixedly installed on air chamber In 5 inner bottom wall, in order to be used for the processing of the wall for coordinating flange head 2 on locating piece 4.Or, locating piece 4 and air chamber 5 Can be formed in one part, and connection is reliable.

In each embodiment above-mentioned, latch 3 is specifically as follows 40Cr latches.Due to the working environment of latch 3 more severe, The shearing for bearing at work is larger, is easily bent fracture, is the material of latch 3 from the higher 40Cr of intensity, is conducive to protecting The service life of card latch 3, practicality are higher with economy.Certainly, latch 3 can also be other materials part.

In this specification, each embodiment is described by the way of going forward one by one, and what each embodiment was stressed is and other The difference of embodiment, between each embodiment identical similar portion mutually referring to.

Above flange fixture head provided by the utility model is described in detail.Specific case used herein Principle of the present utility model and embodiment are set forth, the explanation of above example is only intended to help and understands this practicality New method and its core concept.It should be pointed out that for those skilled in the art, without departing from this reality On the premise of with new principle, some improvement and modification can also be carried out to this utility model, these improvement and modification also fall into In this utility model scope of the claims.
