In the present embodiment, as shown in fig. 1 and 2, the positioning pin 2 is provided on the lower surface 14 of the positioning block 1, the positioning pin 2 is further provided rotatably on a base plate (not shown) to be arc-welded and clamped, and the positioning block 1 is rotatable on the base plate with the axial center of the positioning pin 2 as a pivot point.
Finally, in the present embodiment, as shown in fig. 1 and 2, the adjustment pads 3 are provided on the positioning side of the positioning block 1, and when a plurality of adjustment pads 3 are provided, the adjustment pads 3 are sequentially arranged in a direction away from the positioning side 11 and are detachably connected to the positioning block 1. Wherein the outermost shim 3 remote from the locating side 11 is intended to be applied to a workpiece to be welded.
As can be seen from the above, since the positioning element can be rotated on the base plate by means of the positioning pin 2, in practical application, as shown in fig. 3 and 4, the positioning block 1 of the positioning element can be rotated to any angle according to the reference surface 101 of the to-be-welded workpiece 100, so that the positioning side 11 of the positioning block 1 is opposite to and parallel to the reference surface 101 of the to-be-welded workpiece 100, and then one or more adjusting shims 3 with the same length as the vertical distance are arranged on the positioning side 11 according to the vertical distance between the positioning side 11 and the reference surface 101 of the to-be-welded workpiece 100, so as to ensure that the adjusting shim 3 far from the outermost side of the positioning side 11 can be attached to the reference surface of the to-be-welded workpiece 100, thereby meeting the positioning requirement of the to-be-welded workpiece 100. Therefore, the arc welding fixture can meet the welding requirement of positioning the workpiece in any posture, and the welding efficiency is improved while the quality of the welding seam is improved.
Specifically, in the present embodiment, as shown in fig. 1 and 2, the axis of the positioning pin 2 passes through the axis of the positioning block 1, so that the positioning pin 2 and the positioning block 1 can be coaxially disposed, and the positioning block 1 can be rotated about the axis thereof when rotated. In addition, in the present embodiment, the positioning pin 2 and the positioning block 1 may be integrally formed, but it is needless to say that the positioning pin 2 and the positioning block 1 may be fixed by a detachable connection method in actual use, and in the present embodiment, the connection method between the positioning block 1 and the positioning pin 2 is not particularly limited.

Therefore, the adjusting gaskets 3 can be fixed on the positioning block 1 through the locking screws 4, so that the number of the adjusting gaskets 3 can be correspondingly increased or decreased by workers according to requirements.
In the present embodiment, as shown in fig. 1 and 2, the locking screw 4 specifically includes: a cap 41 and a stud 42. Wherein the cap 41 and the fastening side 12 of the positioning block 1 are arranged opposite to each other, and the stud 42 is connected to the cap 41 and arranged coaxially. In actual assembly, as shown in fig. 1 and 2, the stud 42 penetrates through the positioning block 1 from the fastening side 12 to the positioning side 11 of the positioning block 1 in a direction perpendicular to the axis of the positioning pin 41, so that the stud 42 can be respectively screwed with the positioning block 1 and each adjusting shim 3, and the cap 41 can abut against the positioning side 11 of the positioning block 1, thereby locking each adjusting shim 3. When there are a plurality of adjusting shims 3, a worker may set a plurality of adjusting shims 3 having the same thickness according to the distance between the positioning side 11 of the positioning block 1 and the reference surface 101 of the workpiece 100 to be welded, or may set a plurality of adjusting shims 3 having different thicknesses.
In addition, as shown in fig. 1 and 2, the positioning member of the present embodiment preferably further includes: and a washer 5, wherein the washer 5 is sleeved on the stud 42 of the screw 4 and is positioned between the cap part 41 and the fastening side 12. Therefore, the gasket 5 can prevent the cap 41 from pressing the fastening side 12 of the positioning block 1 due to the excessive locking force of the screw 4, thereby protecting the positioning block 1.
A second embodiment of the present invention relates to an arc welding jig including: a base plate (not shown), at least one positioning member rotatably disposed on the base plate as described in the first embodiment.
The positioning parts are arranged on the base plate, so that the positioning of a plurality of reference surfaces of the workpiece to be welded can be realized, the positioning performance of the workpiece to be welded on the base plate is further improved, and the workpiece to be welded has a better positioning effect.
A third embodiment of the present invention relates to a positioning method of a positioner for an arc welding jig according to the first embodiment, as shown in fig. 5, including the steps of:
and step 510, determining the placing position of the reference surface 101 of the workpiece 100 to be welded on the base plate of the arc welding fixture.
And step 520, judging whether the reference surface 101 of the to-be-welded workpiece 100 is opposite to and parallel to the positioning side 11 of the current positioning block 1.
and 540, if the reference surface 101 of the workpiece 100 to be welded is judged to be opposite to the positioning side 11 of the current positioning block 1 and to be parallel, measuring the vertical distance between the positioning side 11 and the reference surface 101.
One or more spacer shims 3, of equal length to the vertical distance, are prepared 550 based on the measured vertical distance.
And 560, arranging the adjusting gaskets 3 in sequence towards the direction far away from the positioning side 11, and locking and fixing the adjusting gaskets with the positioning block 1, so that the adjusting gasket 3 at the outermost side far away from the positioning side 11 can be attached to the reference surface 101 of the workpiece 100 to be welded, thereby realizing the positioning of the workpiece 100 to be welded.
Therefore, by means of the rotation characteristic of the positioning block 1 on the substrate, the welding requirement of the positioning block 1 on positioning the workpiece 100 to be welded in any posture can be met, and the welding efficiency is improved, and meanwhile, the quality of a welding seam is improved.
And, as a preferable scheme, after determining that the reference plane 101 of the to-be-welded workpiece 100 is opposite to and parallel to the positioning side 11 of the current positioning block 1, i.e. after step 420, and before measuring the perpendicular distance between the positioning side 11 and the reference plane 101, i.e. before step 440, the method further comprises the following steps:
and step 521, locking and fixing the positioning block 1 with the substrate in the current posture. Specifically, locking pieces such as bolts can be adopted to lock the positioning block 1 and the substrate, so that the positioning block 1 is not prone to shaking when the workpiece 100 to be welded is positioned, and the positioning accuracy of the workpiece 100 to be welded is improved.
