Abstract
The utility model discloses a clamping fixture used for welding sleeves with a same central line, aiming at overcoming the defects that two cylindrical steps of a spindle for two sleeves welded on a same central line are used as positioning shaft necks, and after welding, the spindle is difficult to take out due to stress deformation, or even the welding parts are damaged. The clamping fixture comprises the positioning shaft necks arranged at two sides of the spindle and used for positioning of the welding of the sleeves, spacer bushes for fixing the spacing, and lock nuts for fixing the sleeve, wherein the positioning shaft necks are formed by that a cone shaft neck is arranged at the positioning part of the sleeve of the spindle, and the cone shaft neck is sheathed with an inner taper sleeve with the external circular surface used as the positioning shaft neck. As the positioning shaft necks for the sleeves are formed by that the cone shaft neck is sheathed with the external circular surface of the inner taper sleeve, after the welding is finished, the end of the spindle positioned at the small end of the cone shaft neck is beaten lightly, then the cone shaft neck can be easily released from the interior of the inner taper sleeve, therefore, the positioning is accurate due to conical surface contact, the operation of taking down the spindle is time-saving and labor-saving, and the welding parts can be ensured not to be damaged when the welded sleeve is taken out from the spindle.
Description
Technical field
The utility model belongs to outfit, the mold that specifically a kind of weld job is used.
Background technology
Often make some tooling devices by oneself in machinery repairman factory, can run on the tooling device and two sleeves will be welded on same the center line of a workpiece.For the center line that guarantees two sleeves on the same line, generally be to locate to sleeve as locating journal with the cylinder step at mandrel two ends earlier, need to be about to two sleeves of welding to be through on two cylinder steps of same mandrel, to weld behind the mandrel centering, and then mandrel is taken out.
Above-mentioned cylinder step with mandrel as the shortcoming that locating journal welds is, after the sleeve welding is finished, because welding deformation, there is bigger internal stress in weldment, can't normally be released in sleeve with mandrel in the location, must impact energetically just and can take out with hammer, above-mentioned way not only wastes time and energy, and good workpiece is damaged might to make welding when impacting.
The utility model content
Technical problem to be solved in the utility model is, overcome two sleeves that prior art is welded on the same center line and make locating journal with two cylinder steps of mandrel, the welding back produces distortion because of weldment, waste time and energy when taking out mandrel, even the shortcoming of damage weldment, the concentricity line sleeve of a kind of welding mold is provided.
In order to solve the problems referred to above that prior art exists, the utility model is to adopt following technical proposals to realize: mold comprises mandrel, what the mandrel both sides were provided with is the locating journal of two welded sleeve location, the spacer that two sleeve determining deviations are used, and be fixed the locking nut that sleeve is used, described locating journal is, is provided with the cone axle journal at the place, sleeve location of mandrel, is with on the cone axle journal that endoporus and cone axle journal adapt, the periphery of outer border is as the inner conical drogue of locating journal.
The utility model also has following technical characterictic:
Two locating journals of described mandrel both sides, wherein a side is the cylinder locating journal, opposite side is for being with the inner conical drogue of its periphery as locating journal on the cone axle journal; Be positioned on the mandrel on the threaded rod of nearly cone axle journal small end one side, be with the bowl-type pad that its rim of a bowl leans against soldered sleeve outer face, locking nut is screwed on the threaded rod, is pressed on the outer face of bowl-type pad;
On the threaded rod of cone axle journal small end one side of described mandrel, be screwed with and compress the clamp nut that inner conical drogue is used.
Advantage of the present utility model and good effect are, because the concentricity line sleeve of welding is the cone axle journal with the locating journal on the mandrel, with the periphery that is enclosed within inner conical drogue on the cone axle journal as locating journal, treat jacket casing is finished welding on locating journal, after workpiece cools off fully, knock the mandrel termination that is positioned at cone axle journal small end gently, the cone axle journal of mandrel can easily be deviate from inner conical drogue, even if having internal stress after the welding, little to influence between the inner conical drogue of conical surface contact and the axle journal, and conical surface contact location accurately, mandrel takes off time saving and energy saving, and having guaranteed can be not destroyed when the good workpiece of welding is got mandrel.
Description of drawings
Fig. 1 is a cross-sectional schematic of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Among Fig. 1, welding positioner comprises mandrel 1, and what be provided with in the left and right sides of mandrel 1 is two and is welded on the workpiece 62 location of the sleeve on the same center line and uses locating journal, is the spacer 3 that two sleeves, 2 determining deviations are used, and the locking nut 7 of clamp sleeve 2 usefulness.The set-up mode of described mandrel 1 is, be provided with the detection axle journal 1.5 that centering is used at the two ends, the left and right sides of mandrel 1, be provided with successively from left to right: for the endoporus locating journal of the retaining platform 1.1 of the left end head location usefulness of left side sleeve 2, left side sleeve 2, be enclosed within on the mandrel 1 spacer 3 that two sleeves, 2 determining deviations are used about being, the endoporus locating journal of right hand sleeves 2 and the locking nut 5 that compresses right hand sleeves 2 right sides in two centres of detecting axle journals 1.5.
Two locating journals that described mandrel 1 left and right sides is provided with are that for left side sleeve 2 endoporus location is cylinder locating journal 1.2; For right hand sleeves 2 endoporus location, be on mandrel 1, to be positioned at right hand sleeves 2 endoporus places to be provided with cone axle journal 1.3, be with the inner conical drogue 4 of the periphery of its outer border on the cone axle journal 1.3 as locating journal 4.1.Be positioned on the mandrel 1 on the threaded rod 1.4 of nearly cone axle journal 1.3 small ends one side, be with the bowl-type pad 6 that its rim of a bowl leans against soldered sleeve 2 outer faces, locking nut 7 is screwed on the threaded rod 1.4, and is pressed on the right side of bowl-type pad 6.
Two locating journals on the mandrel 1, can adopt the above-mentioned inner conical drogue 4 that on cone axle journal 1.3, is with, with the periphery of inner conical drogue 4 structure as locating journal 4.1, for the structure that makes welding positioner both simple, make things convenient for the taking-up of mandrel 1 again after sleeve 2 welding, the locating journal that adopts above-mentioned both sides different structure is best.
For inner conical drogue 4 is not moved right, on the described mandrel 1, be positioned on the threaded rod 1.4 of small end one side of nearly cone axle journal 1.3, be screwed with the clamp nut 7 that compresses inner conical drogue 4 right sides.
