The board-like drying cylinder backing ring welding tooling of asphalt mixing plant spring of the utility model is detailed below
The welding method of progress, may include following steps:
Step 1: backing ring positioning device 1 is positioned between roller 5 and backing ring 2, i.e., roller 5 is placed on chassis 7
And on carrying roller 6, place scribing tooling in 5 length side of roller, measurement adjust the central axis of the scribing tooling and roller 5 and
2 two sides width of backing ring is pressed in maintenance after the bottom surface of pedestal is parallel with the maximum plain line of roller, the backing ring position in roller outer circle
Side and center line correspondence find and mark three positions line, slowly rotate roller, the scriber of scribing tooling is made to mark this three circles
Contour, then divide equally the position for marking the pedestal 1-2 of each backing ring positioning device 1 on three circumferences of cylinder outer circle by the diameter of roller
Line fixes at the both ends of each pedestal 1-2 with roller spot welding respectively.
A wherein support 1-1 is attached with fixing bolt 1-4 and one end of pedestal 1-2, another support 1-1 wouldn't connect
It connects, 2 handling of backing ring suit is placed on the periphery of each pedestal 1-2 of 5 periphery of roller, is measured in the backing ring 2 in full circle week
Circular surfaces to gap between roller in place after, then another support 1-1 installed by fixing bolt, and available pneumatic impact spanner is tightened.
Step 2: accurate adjustment backing ring 2 arrives welding position, first adjusts the circular runout (referring to Fig. 3 and Figure 10) of backing ring 2, passes through
The radiai adjustment bolt 1-5 of each backing ring positioning device 1 adjusts backing ring circular runout.By on backing ring diameter dimension circumference divide equally 16 etc.
Point, the magnetic stand of dial gauge is placed in the upper surface on chassis 7, dial gauge, the touching of dial gauge are installed on the support of dial gauge
Head touches the outer round surface of backing ring 2.Slowly rotation roller 5 records the reading of the dial gauge of 16 points, calculates backing ring circumferentially
The circular runout difference of each point is analyzed and adjusts each radiai adjustment bolt 1-5.This measurement, adjustment process is repeated, until
Run-out error≤1.2mm of backing ring, that is to say, that reach backing ring outer round surface for coaxial on the basis of roller centerline
Spend error≤1.2mm design requirement.The cylindricity error of backing ring is detected simultaneously.Adjust backing ring axial runout again, (referring to Fig. 3 and
Figure 11), the radiai adjustment bolt 1-6 of each backing ring positioning device 1 is for adjusting backing ring axial runout, by backing ring diameter dimension circumference
It is upper to divide equally 16 equal parts, the magnetic stand of dial gauge is placed in the upper surface on chassis 7, dial gauge is installed on the support of dial gauge,
The contact of dial gauge touches one side end face of backing ring width.Slowly rotation roller records the reading of the dial gauge of 16 points, calculates support
The axial runout difference of circle circumferentially each point, analyzes and adjusts and be respectively adjusted axially bolt 1-6.This measurement is repeated, adjusts
It is had suffered journey, until run-out error≤1.0mm of backing ring, that is to say, that backing ring width end face outside is for roller centerline
On the basis of the error of perpendicularity≤1.0mm design requirement.The total axial run-out error of backing ring is detected simultaneously.So that backing ring
Position reaches following requirement: one week circle of backing ring radial rotary bounce≤1.2mm, maximum offset does not surpass between roller and backing ring
Cross 1.6mm, total run-out≤1mm of backing ring axial direction, center carpenters square cun tolerance+1mm between two backing rings.
Step 3: weldering riveting bracket is cross-placed in roller and backing ring, gets latch plate quantity ready, lifts by crane spring by spot welding positioning
Plate is hung on weldering riveting bracket, and latch plate is filled in design requirement position in gap between backing ring and drying cylinder, measurement adjustment latch plate
One end and backing ring internal circular surfaces and the other end and roller outer round surface docile, spot welding positioning.Rotating cylinder and one by one spot welding spring
Plate is in place.
Step 4: butt welding molding continues to be repeatedly detected each size of backing ring, latch plate, geometric tolerance, after confirmation is errorless, rotation
Tumbler cylinder, it is real one by one to weld spring sheet metal forming.
Step 5: backing ring positioning device is removed.
It can be seen that utility model has the advantages that
1, structure is simple, and processing cost is low.Either inside can complete blanking, welding, drilling and tapping, all works of assembling
Sequence does not need external coordination or outsourcing.It significantly reduces the production cost, there is good economy.
2, easy to operate.All connections, regulating device are that bolt, screw thread auxiliary structure securely and reliably effectively shorten
Duration.
3, detachable structure.Movable bearing support is removed before the installation of backing ring positioning device, to backing ring
Movable bearing support is reinstalled again after being formed directly into from movable bearing support side, easy to operate flexible, labor intensity is low.
4, for the backing ring of different specification size, this drying cylinder backing ring positioning device can be used, with excellent general
Property.
5, it importantly, ensure that the group weldering of backing ring, mounting design and technique requirement and quality requirement, has fully met dry
The requirement of dry cylinder.
It is readily apparent that above description and record is only citing rather than in order to limit the disclosure of the utility model
Content, application or use.Although describing and being described in the accompanying drawings embodiment, the utility model in embodiment
Do not limit by attached drawing example and be described as in embodiment it is now recognized that optimal mode to implement the religion of the utility model
The specific examples led, the scope of the utility model will include any implementation for falling into the description and appended claims of front
