Embodiment 1: as shown in Figure 1, drive shaft includes shaft 1 and several workpiece to be welded being connected on 1 axis direction of shaft
2, the workpiece 2 after welding is arranged along 1 axis direction of shaft, and is in special angle between several workpiece 2.A kind of drive shaft welding
Positioning tool, which, which is socketed in shaft 1, positions several workpiece 2, and positioning tool 3 includes to several workpiece 2
Carry out the positioning plate 31 of 1 rotation direction of shaft positioning.In conjunction with Fig. 2, positioning plate 31 runs through the positioning offered for passing through shaft 1
Hole 311, the diameter of the location hole 311 is identical as the outer diameter of the shaft 1, so that after positioning tool 3 and shaft 1 are socketed, it is fixed
Position tooling 3 is fitted closely with shaft 1.Shaft 1 is symmetrically arranged with two the first reference lines 11 along its cylinder, and wherein the one of positioning plate 31
A side extends outwardly along the diameter of the location hole 311 equipped with the second reference line 312.
In use, positioning plate 31 is socketed by location hole 311 with shaft 1, positioning plate 31 is in 1 periphery of shaft, then
First reference line 11 is aligned with the second reference line 312 and is overlapped, is then aligned one of workpiece 2 with positioning plate 31, by work
Part 2 and shaft 1 are welded.Then positioning plate 31 is moved along the axis direction of shaft 1, until positioning plate 31 is in shaft 1
Designated place, the second reference line 312 of positioning plate 31 is aligned with the first reference line 11 in shaft 1 and is overlapped, then by another
Workpiece 2 is aligned with positioning plate 31, and workpiece 2 and shaft 1 are welded.The setting of positioning plate 31, so that welding several shapes respectively not phase
With workpiece 2 when, it is only necessary to the mobile same positioning plate 31 in shaft 1.First reference line 11 sets on positioning plate 31
It sets it is also possible that the angle between workpiece 2 mutually determines, and then guarantees the angle between several workpiece 2.
As shown in Figure 1, workpiece 2 includes several first workpiece 21 and second workpiece 22.In conjunction with Fig. 3, positioning plate 31 includes the
One positioning region 313, the second positioning region 314 and third positioning region 315, the first positioning region 313, the second positioning region 314 and third are fixed
Position portion 315 is away from location hole 311 center position protrusion, and the first positioning region 313, the second positioning region 314 and third position
Remotely located 311 side of hole in portion 315 is provided at circumferentially spaced along the circle of location hole 311.Second reference line 312 is in third positioning region
On 315, and third positioning region 315 is symmetrical along the second reference line 312.It is arranged so that when making positioning tool 3,
After the position of third positioning region 315 determines, the position of the first positioning region 313 and the second positioning region 314 can be according to the second benchmark
Line 312 determines relatively, and then guarantees the angle between the first positioning region 313, second positioning region 314 and third positioning region 315,
And then ensure to be welded on the angle in shaft 1 between several workpiece 2 according to positioning tool 3.Similarly, the second reference line 312 can also
To be on the first positioning region 313 or the second positioning region 314, when the second reference line 312 is on the first positioning region 313, the
One positioning region 313 is symmetrical along the second reference line 312；When the second reference line 312 is on third positioning region 315, third is fixed
Position portion 315 is symmetrical along the second reference line 312.
In conjunction with Fig. 4, in use, positioning plate 31 is slid onto designated position, so that the first reference line 11 and the second reference line
It is aligned and is overlapped between 312, be then aligned at the both ends of the first workpiece 21 with the both ends of the first positioning region 313, then by the workpiece 2
It is welded with shaft 1；Continue to slide positioning plate 31 to designated position so that the first reference line 11 and the second reference line 312 it
Between be aligned be overlapped, then the both ends of another the first workpiece 21 are aligned with the both ends of the second positioning region 314, then by the workpiece
2 are welded with shaft 1, are circuited sequentially, and several the first workpiece of workpiece 21 are carried out positioning welding according to positioning plate 31, so that weldering
Specific angle is presented in several first workpiece 21 and the second reference line 312 after connecing.
The two sides that above-mentioned tooling is mainly used in the first workpiece 21 can be with the first positioning region 313 or the second positioning region 314
Or third positioning region 315 two side superimposeds the case where.But when drive shaft also needs to weld second workpiece 22, second workpiece 22
Two sides are not overlapped with the two sides of the first positioning region 313, the second positioning region 314 and third positioning region 315, in order to solve this feelings
Condition offers first through hole 316 as shown in figure 5, running through on positioning plate 31, corresponding, in conjunction with Fig. 6, opens on second workpiece 22
Equipped with the second through-hole 221, when second workpiece 22 and shaft 1 fit closely, first through hole 316 and the perforation of the second through-hole 221 are connected.
It is overlapped in use, only needing for the second through-hole 221 to be aligned with first through hole 316, that is, can guarantee second workpiece 22 and the second benchmark
Specific angle is presented in line 312.
The edge of workpiece 2 is equipped with chamfering along 1 axis direction of shaft.The setting of chamfering prevents operator in running fix
When plate 31 because edge is too sharp and coughs up hand.
The course of work: in use, positioning plate 31 is slid onto designated position, so that the first reference line 11 and the second reference line
It is aligned and is overlapped between 312, connecting plate 4 and shaft 1 are carried out by abutting fixation by bolt.When needing to weld the first workpiece 21,
The both ends of first workpiece 21 are aligned with the both ends of the first positioning region 313, are then welded the workpiece 2 with shaft 1, successively
Several first workpiece 21 are carried out positioning welding according to positioning plate 31 by circulation；When needing to weld second workpiece 22, second is led to
Hole 221 is aligned with first through hole 316 and is overlapped, and then welds second workpiece 22 and shaft 1.
Embodiment 2: a kind of drive shaft welding positioning tool, as shown in fig. 7, its difference from Example 1 is, positioning
Plate 31 raises upward to form connecting plate 4 far from the side of the second reference line 312 along the edge of location hole 311.In conjunction with Fig. 8, even
It is pushed against and is fixed by bolt 6 between fishplate bar 4 and shaft 1.When the first reference line 11 is aligned with the second reference line 312 be overlapped when
It waits, connecting plate 4 and shaft 1 is carried out by abutting fixation by bolt 6, and then positioning plate 31 and shaft 1 are fixed.So set
It sets so that all not needing user during workpiece 2 is aligned with positioning tool 3 helps always positioning plate 31, also reduction is welded
The probability of people's injury of positioning plate 31 is helped in the process.
The two sides of first positioning region 313, the second positioning region 314 and third positioning region 315, which are equipped with, limits workpiece 2
Limit plate 5.After positioning plate 31 is moved to designated position, workpiece 2 is abutted with shaft 1, workpiece 2 is in limit plate 5 at this time
Interior, limit plate 5 limits workpiece 2, prevents workpiece 2 from circumferentially rotating in the welding process along shaft 1, causes positioning not
Standard influences the angle between workpiece 2.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
