Component welding · inspection-led material flow

Automobile Shock Absorber Intelligent Welding Production Line

Feel free to contact us on industrial robots and we will gladly answer any of your questions.

Two configurable production-line concepts connect component loading, pressing, welding, in-line checks, leak detection and physical reject isolation.

The scope shown here covers welded shock-absorber components. Final line design follows the actual workpiece family, joint map, inspection method and plant material flow.

Separate the welded component routes before designing the line

The source layouts describe two different part families. They are presented as separate line concepts so stations, handling and checks stay tied to the correct workpiece.

Front shock absorber component line

Pressing, double welding, forming and punching, oxide grinding, bracket-related welding, dimensional inspection and leak detection are connected in one routed concept.

Secondary component line

The second route covers lifting-ring, yoke and lower-guard-plate related welding steps with orientation, appearance and part-position checks.

Quality decision path

Put inspection and part disposition inside the production flow

The line concepts place checks before final offloading so accepted and rejected parts can follow different physical paths.

Process condition

Pressing, welding, cooling, punching and grinding establish the workpiece condition before downstream checks.

Part and position checks

The second route includes appearance, orientation, cylinder geometry and rolled-marking-position checks where applicable.

Dimensions and leak

In-line dimensional inspection and leak detection create explicit pass/fail decisions in the documented routes.

Physical disposition

Accepted parts leave the line; rejected parts are moved to a separate isolation path.

Traceability boundary: the layouts make the station and disposition path visible. Data capture, record retention and serial-level traceability are project-defined requirements and are not assumed by this page.

The protected component naming stays unchanged; the route identifies the two bracket operations by location.

Line concept 02

Automobile shock absorber (lifting ring, yoke, lower guard plate) intelligent welding production line

This route connects part presence and orientation checks with cylinder-bottom welding, lifting-ring or yoke operations, optional guard-plate welding, dimensions and leak detection.

The route uses conveyor, manipulator, slide and turntable handling according to the documented line configuration.

Cylinder-bottom pressPress the cylinder-bottom component automatically.
Cylinder-bottom direction and presence checkCheck whether the cylinder bottom is correct. Failed parts → isolation box.
Cylinder checksCheck front/back orientation, outside diameter and rolled-marking position. Failed parts → isolation box.
Cylinder-bottom seam weldingComplete the cylinder-bottom seam weld.
Turntable appearance check — firstInspect appearance after seam welding. Failed parts → isolation box.
Transfer to the next stationA handling robot moves the workpiece to the next operation.
Lifting-ring / yoke projection weldingProjection-weld the lifting ring or yoke where applicable.
Turntable appearance check — secondInspect appearance after projection welding. Failed parts → isolation box; accepted parts → step 09.
Lifting-ring / yoke dual-gun weldingComplete the routed lifting-ring or yoke welding operation.
Guard-plate / spring-plate weldingWeld the relevant component when involved; otherwise go directly to step 11.
Weld-oxide grindingGrind the defined weld-oxide area.
In-line dimensional checkInspect the defined dimensions. Failed parts → isolation box.
Leak detection → offloadComplete leak detection and offload accepted parts. Failed parts → isolation box.
Accepted route
Checks passed → normal offload
Rejected route
Checks failed → isolation area

Customer case line configuration

Total production line personnel input: In addition to material delivery personnel, the production line personnel input 1-2 people (1 person for spring plate welding station (some products do not have this process), 1 person for leak detection/loading)

Applicable welding objects: automobile shock absorbers

Number of robots: 3 welding robots, 2 handling robots.

Automation rate: 99%

In-line conveying form: conveyor line, truss manipulator, slide, turntable, material rack and material frame.

Flexible switching form: quick change of fixtures + program call.

This page presents a customer case. EVST adapts the solution and the design to each customer's actual project.

Flexible changeover

Change fixtures and call the matching process program

Product variants still require confirmation of datum strategy, tooling interfaces, station compatibility and the inspection recipe before the changeover method is fixed.

Fixture interface

Define locating points, clamps, connectors and safe access for each workpiece variant.

Program call

Link the selected fixture and workpiece family to the corresponding station sequence and robot programs.

Verification after change

Confirm workpiece presence, orientation, joint access and required inspection points before returning the line to production.

Configuration comparison

The three testing-machine resources below are separate downstream products; they are not included in the welding-line concepts shown on this page.

Scope boundary: this page addresses component pressing, welding, handling and the stated in-line checks. Oil filling, gas charging, damper assembly and damping-force testing are outside the shown welding-line scope unless defined as a separate project requirement.

FAQ

Shock absorber welding line questions

Does this page describe a complete shock absorber assembly line?

No. It describes the component pressing, welding, handling and stated inspection routes shown in the source layouts. Other assembly and functional-test operations require separate definition.

Why are there two line concepts?

The layouts cover different welded workpiece families and different station sequences. Keeping them separate prevents equipment and process assumptions from crossing between parts.

How are rejected parts handled?

The documented routes create pass/fail decisions at dimensional and leak checks, followed by a separate isolation path for rejected workpieces.

What does flexible changeover require?

The published method combines quick fixture change with program call. The project still needs to confirm each variant, datum, fixture interface, station route and inspection recipe.

What does “rolled marking position” mean here?

It is the position of the rolled identification marking on the cylinder, checked as part of the documented orientation and geometry sequence where applicable.

What should I send for a line review?

Send part drawings, joint details, materials, fit-up conditions, variants, required production route, inspection and traceability requirements, floor space, utilities and the intended loading method.

Application review

Start with the workpiece, joints and acceptance route
