The choice of advanced new type of flexible modular fixture and industry applications

Committed to the new type of flexible modular fixture, the flexible welding equipment, automated production equipment and improve the production efficiency of the solution development and operations.

A flexible, modular fixture definition

Flexible modular fixture is a kind of made by beforehand good module composition of standardization, seriation, generalization, and the link between modules, fixed and pressure in hole as a benchmark, to achieve quick lock with lock pin, between modules and modules can be adjusted according to the actual size of workpiece can, achieve two-dimensional or three-dimensional space structures, workpiece positioning of industrial equipment.

Second, the flexible modular fixture is introduced

1, flexible modular fixture

(1) basic parts: supporting artifacts and all kinds of fixture module of the platform.

(2) support: it is to ensure the workpiece in machining process to a certain height requirement, and will support a position on the platform of the components.

(3) positioning: to ensure the workpiece in machining process reaches a certain size accuracy requirement, and the workpiece positioning device.

(4) adjust: is used for components and artifacts the potential difference between the clearance adjustment.

(5) pressure: is to ensure that the displacement of workpiece in machining process is not, and the workpiece compression based on platform or components of components.

6. Lock: is to ensure that components and components between the positioning of the lock.

All landowners fitting: is applied to the connection between the components and components.

　　2, the classification of the flexible modular fixture

(1) according to the aperture is divided into: 28 and Φ Φ 16 two big series, series of 28 hole distance is 100 mm, the pitch of 16 series of 50 mm

(2) according to the structure is divided into: two-dimensional flexible modular fixture and three-dimensional flexible modular fixture

(3) according to the materials are divided into: steel and casting and composite board

Three, flexible modular fixture features

1, economy

Flexible modular fixture is a kind of universal fixture can free combination, can adapt to different workpiece shape, several sets of fixture system can replace a large number of the high cost of special tooling, after using the tooling, can save due to product changes into the specialized equipment and tooling cost and time. In many varieties, personalized car production, its economical efficiency is especially obvious.

Foreign data have shown that the cost of more than 9 sets of special welding jig (5 ~ 6 sets) in our country has more than a set of flexible fixture. At present, China's automobile manufacturing enterprises increase each year dozens of sets of special welding jig is very common, selects the flexible fixture economy is obvious.

　2, flexible

Flexible modular fixture can be combined in three-dimensional space. Modular system in the installation, adjustment and clamping workpiece perfectly reflected its general function, on the welding of large workpieces, the more prominent characteristics.

The other side of the flexibility in easy operation. On the bench and module, all with 12.5 mm and 25 mm as multiple dimensions can be found directly, coupled with a small amount of adjustment, can be convenient accurate positioning.

3, accuracy

Flexible modular fixture of all module processing precision is high, working platform in the range of 2000 mm to ensure that the positioning hole position error within + / - 0.1 mm, can completely meet the needs of the welding process.

Used in assembly or during the welding process, positioning, clamping device, connecting blocks of and support, to accurate positioning of workpiece, need welding workpiece can be stably fixed in each anchor point or location on the surface. If the geometry size of workpiece itself is not accurate, also can be detected quickly in the pretreating process will be eliminated.

4, repeatability

Use CAD and Pro/E design, can be very easy to simulate assembly samples and precise assembly module size can guarantee accuracy.

5, durability

In working platform and module structure design, fully consider the use of stiffness and strength requirements, each standard 2000 mm x 1000 mm work platform load can reach 10 t, and can ensure the accuracy of its repeated positioning and clamping.

The surface of the working platform and module through special processing, make the welding splash when the work is not easy to stick on the surface.

Positioning and clamping bolt pin surface after quenching treatment, make its not easy to wear and durable.

Four, flexible modular fixture applications

1, flexible modular fixture application industry

Flexible modular fixture is widely applied in automobile, engineering machinery, ship building, aerospace, rail transport, structural welding, sheet metal enclosure, stage, truss welding, bicycle, motorcycle manufacturing, and welding robots or form a complete set of special welding machine and so on.
