EROWA fixture description and development

What is EROWA?

The word erowa is derived from the abbreviation of the three words EDM, tool manufacturing and automation in German. This word also clearly expresses the goals we have set up and pursued since the company was founded in 1970. In 1983, the first universal tool system for tool and die manufacturing was patented and put on the market. In 1987, the first robot for automatic loading and unloading of workpieces and electrodes was launched. These products are still continuously improving.

This type of fixture is designed according to the mechanical principle of the double rocker mechanism in the planar four-bar mechanism, and its basic structure is composed of four components such as a connecting rod, a frame, and two connecting rods.

EROWA type:

Horizontal type. Vertical type. Push-pull type. Latch type. Welding group vertical type. F-type clamp cyan. Type household cyan and pneumatic Gan etc.

EROWA fixture application range:

It is widely used in the manufacture of electronic parts, posture equipment, assembly of sheet metal iron furniture for automobiles, motorcycles, bicycles, etc., production of sports equipment, aircraft assembly, qualitative PU molding, toys, handicrafts processing related parts Processing and assembly of fixed clamps, plastic injection products to prevent deformation, wooden products processing plant planing and milling of related parts, Zan, tapping, testing, etc .. Connection of chemical pharmaceutical, food and other industrial pipelines, opening of tank cover Closed and various mass production involves the processing of the object needs to be fixed, and other various occasions that require fixed clamping to complete or work can be used

The machine tool fixture is a device used to hold the workpiece on the machine tool, and is called the "hand" of the machine tool. The use of machine tool fixtures can ensure the machining accuracy of the workpiece, reduce auxiliary working hours, greatly improve production efficiency, and also expand the scope of use of the machine tool to achieve "one machine with multiple capabilities". It is not only used for metal cutting, but also can be used in inspection, assembly, welding parts, production line manufacturing and other processes. EROWA fixture is only a supporting industry, not a pillar industry, but a variety of fixtures must be used in the machining process. Fixtures are indispensable process equipment, and the market potential is huge.

EROWA's central force:

Central tightening force refers to the maximum pressing force of the indenter on the workpiece when the clamp is in the locked position without mechanical deformation. This pressing force is generated when the indenter is adjusted to the nearest position of the mounting seat on the arm. The pressure of the indenter on the workpiece is not constant. It changes with the different positions of the indenter on the force arm. When it is away from the mounting seat, the clamping force decreases.

Features of EROWA:

1. Simple structure and easy installation.

2. The clamped workpiece is quick to load and unload and easy to operate.

3. All parts are electroplated and anti-rust, the surface is smooth and beautiful.

4. For heavy-duty fixtures, the key parts are heat treated to make them have higher strength and wear resistance.

EROWA fixture development prospects:

Unleash the full potential of your machine.

To make your workshop more competitive, you need to remove inefficiencies in the workflow. Manual setup on the machine is the weak link. It is the top priority to make up for the wasted time.

Common problems of EROWA fixtures:

When the two hinge points of the connecting rod and the connecting rod and the hinge point of one of the connecting rod and the frame are in a straight line, the mechanism is in the dead point position. At this time, no matter how much the reaction force of the pressed workpiece is except the destructive reaction force, the indenter cannot be released. This is the dead point clamping principle in mechanical mechanics. In order to avoid the impact of external force load and mechanical vibration in use, the middle hinge point is slightly biased to the inner side of the other two hinge points during design to ensure that the fixture is always maintained under the maximum tension The mechanism locks in a stable state without loosening.
