Description
Technical field
The present invention relates to a kind of axial direction positioning device of ladder pipe fitting on bidirectional boring machine, in particular to a kind of for hydraulic
Ladder pipe fitting axial direction positioning device on bulging axle housing production line.
Background technique
Automobile axle housing is important load-bearing part and force transmission element on automobile, main at present casting and stamping welding method system
It makes, occurs hydraulic expanding-forming automobile axle housing technique in recent years, pipe fitting no-welding-seam, intensity are high and light weight, production process are pollution-free.Liquid
Before pressing bulging, the end machining (axial scale and inner bore chamfering) of ladder pipe fitting is one of important procedure after undergauge, accurate straight
Arm end size can ensure that the correct contact condition of expanding die and pipe fitting, uniform inner bore chamfering are reliably managed when can ensure that bulging
End sealing, straight-arm end size is too long, the excessive failure that will lead to hydraulic bulging process of too short or pipe end inner bore chamfering deviation.
Hydraulic expanding-forming axle housing ladder pipe fitting (see Fig. 1,3) has the feature that 1. pipe fitting has ladder, and ladder is the conical surface,
The conical surface and pipe fitting axis angle are θ；2. the conical surface is with straight-arm part, there are knuckle, radius of corner r；3. pipe fitting side-to-side dimensions
It is asymmetric.After ladder end socket of pipe fitting carries out scale, chamfer machining, strict guarantee is needed: the 1. length of pipe fitting both ends straight-arm part, or
Length of the bulging zone centerline to both ends of the surface.2. pipe fitting left and right ends inner chamfer is uniform；3. pipe fitting left and right ends is coaxial
Degree.
It realizes ladder end socket of pipe fitting processing request, needs to consider: 1. accurate positioning function, it being capable of axial scale；2. alignment function, energy
It is enough that pipe fitting bulging zone centerline is positioned.3. centering function, pipe fitting automatically centering at two ends, to guarantee the concentricity at both ends；
4. the axial direction positioning device of versatility, multiple tracks tube end maching process can be general, or the component by replacing very little is realized and is led to
With；5. controllability is suitable for the processing of different Size ladder pipe fittings end face by adjusting.To the difficulty of ladder pipe fitting axially position
Point is: 1. there are knuckles for the pipe fitting conical surface and straight-arm part, and the measurement of straight-arm partial-length is made to lack accurate benchmark；2. pipe fitting
It is left-right asymmetry, it is not easy to find bulging zone centerline position.
Currently, the document about pipe fitting centering is more, Chinese patent (CN104492864 A) discloses a kind of aluminum pipe centering
Apparatus for correcting respectively drives left and right V-type centering component by two cylinders in left and right and does reversed equivalent movement, realizes that pipe fitting both ends are closed
It is symmetrical in base；Chinese patent (CN105234226 A) discloses a kind of Full-automatic tube bending machine automatic centering mechanism, passes through cylinder
Drive side optical axis mobile, mate gear rackwork makes other side optical axis synchronous relative motion, drives left and right slideway same therewith
Walk centering.The above mechanism, directly driven by cylinder or cylinder mate gear rackwork to make left and right centering component opposite etc.
Amount moves the centering, it can be achieved that pipe fitting and lathe, but is not suitable for the axially position of hydraulic expanding-forming axle housing ladder pipe fitting: 1. can not
Find straight-arm portion size measuring basis；2. pipe fitting asymmetric for left and right, though the symmetrical center positions of entire pipe fitting can be found,
But bulging zone centerline position cannot be found；3. by the centering of pipe fitting both ends, when Boring machine processing, is fitted without space.
Currently, the document about pipe fitting scale is more, research object is metal straight pipe, and the datum level of pipe fitting scale is pipe
Part end face is not involved in the problems, such as finding scale datum level, is not suitable for the scale of hydraulic expanding-forming axle housing ladder pipe fitting.
Summary of the invention
To solve the processing of hydraulic expanding-forming axle housing ladder end socket of pipe fitting, lacks accurate scale benchmark, is not easy to find in bulging area
Heart line and need to be to pipe fitting automatically centering at two ends the problems such as, the present invention provides a kind of hydraulic expanding-forming axle housing ladder end socket of pipe fitting processing axis
