Welding process hole and convex bud, the first big tooth plate 1-2 and the second largest tooth plate 1-1 are left and right part, convex bud is mirror symmetry relationship, first
Big tooth plate 1-2 and the second largest tooth plate 1-1 material are Q235B, required precision are as follows: 5 ± 0.1mm of thickness, welding process hole Φ 6 ±
0.1mm, centre boreFlatness 0.15mm, appearance profile degree 0.05mm；2) it is equipped on tooth plate 1-3 two small
Tooth, centre bore, tooth plate 1-3 two small is identical, material Q235B, required precision are as follows: 6 ± 0.1mm of thickness, centre boreFlatness 0.1mm, appearance profile degree 0.05mm；3) long axis 1-4 material is 20#, required precision are as follows: diameterStraightness Φ 0.06mm, cylindrical surface roughness Ra 1.6；4) using the cylindrical surface long axis 1-4 as benchmark A, straightness Φ
0.1mm；Using the end face the second largest tooth plate 1-1 as benchmark B, the verticality relative to benchmark A is 0.3mm, with tooth plate 1-3's two small
Second tooth center line is second of the big tooth plate 1-2 of benchmark C, mutual depth of parallelism 0.1mm, the first and second largest tooth plate 1-1
The position degree of second tooth of the relatively small tooth plate of tooth is that the tooth form of 0.2mm, the first big tooth plate 1-2 and the second largest tooth plate 1-1 index
The concentricity of circle relative datum A is Φ 0.2mm, and the concentricity of the tooth form reference circle relative datum A of small tooth plate 1-3 is Φ 0.5mm.
The forming method of above-mentioned long axis and tooth plate solder type transmission component, steps are as follows.
S1, successively by tooth plate (1-1,1-2 and 1-3) fine, deburring, light decorations, examine, when fine big tooth plate (1-1 and
Processing welding technique hole on 1-2).
As shown in figure 3, being the first big tooth plate 1-2 (the second largest tooth plate 1-1) fine process schematic diagram, using fine progressive die
Molding is completed, convex bud squeezes out in advance, and centre bore, welding process hole and shape (can guarantee the position in hole and shape using compound fine
Tolerance is set within 0.01mm).As shown in figure 4, being small tooth plate 1-3 fine process schematic diagram, completed using fine compound die small
The molding of tooth plate 1-3 (position of related features of certifiable hole and shape is within 0.01mm).Tooth plate (1-1,1-2 and 1-3) is using essence
Technological forming is rushed, can preferably guarantee flatness, position degree and the profile tolerance requirement of part, tooth plate (1-1,1-2 and 1-3) quality
Consistency it is good, ensure that the stability of weld assembly quality.
S2, successively by long axis 1-4 numerical control processing, natural actual effect, examine.
Fig. 5 is the machining processes schematic diagram of long axis 1-4, long axis 1-4 required precision height (especially straightness Φ
0.06mm it is difficult to ensure that), need high precision machine tool processing (the present embodiment use CKA6140 numerically controlled lathe), after machining due to
The release of cutting stress, long axis 1-4 can be deformed, and need to take the method for nature actual effect (the present embodiment uses 5 days) abundant
It is detected again after release stress, guarantees that part is still qualified products when welding.Long axis 1-4 required precision is high, straightness it is difficult to ensure that,
It is high using numerical control processing, precision, it is detected again after taking the method for nature actual effect sufficiently to discharge stress after processing, prevents detection from missing
Difference.
S3, qualified tooth plate (1-1,1-2 and 1-3) and long axis 1-4 positioning will be examined to be fixed on welding fixture, assembled
Welding fixture is transported to welding post by semiclosed circulating work station afterwards to weld, wherein welding fixture passes through respectively
The cylindrical surface of long axis 1-4, the end face of all tooth plates (1-1,1-2 and 1-3), the welding process hole of big tooth plate (1-1 and 1-2) and small
The tooth of tooth plate 1-3 positions.
Welding stress and cold and hot deformation frequently can lead to the relative position inaccuracy of each part, and welding fixture can pass through
The direction of proof stress and deformation is come in positioning and fixed position, passes through the cylindrical surface of long axis 1-4, all tooth plate (1-1,1-2 and 1-
3) tooth of the welding process hole of end face, big tooth plate (1-1 and 1-2) and small tooth plate 1-3 complete positioning, meet long axis 1-4 and
Between the required precision and 1-4 and tooth plate (1-1,1-2 and 1-3) of tooth plate (1-1,1-2 and 1-3) itself, tooth plate and tooth plate it
Between required precision.
S4, it component after cooling will be welded is mounted in welding cubing and detect, when detection, first pass through V-type fixed block
3-13 guarantees the straightness of long axis 1-4, is positioned the tooth of one of them small tooth plate 1-3 by cubing tooth shape locating block 3-12, so
Afterwards compress long axis 1-4, finally by can along long axis 1-4 move axially detection part detect remaining small tooth plate 1-3 tooth form and
The tooth form and position degree of position degree, big tooth plate (1-1 and 1-2).
Welding cubing has first determined the straightness and one of them small tooth plate 1-3 position degree of long axis 1-4, and then passing through can edge
The detection part of long axis 1-4 axial movement detects the tooth form of remaining small tooth plate 1-3 and the tooth of position degree, big tooth plate (1-1 and 1-2)
Shape and position degree, it is easy to operate, high-efficient relative to three coordinate measurements, it is suitable for batch production.
S5, it will test qualified component antirust treatment.
