German Rohm workholding fixtures Rohm model Rohm price

Rohm workholding fixtures are one of the actuators for vacuum equipment. Generally, using vacuum suction cups to grip products is the most economical method. Vacuum suction cups come in various types; rubber suction cups can operate at high temperatures, silicone rubber suction cups are very suitable for gripping products with rough surfaces, and polyurethane suction cups are highly durable. In addition, in actual production, if oil resistance is required for the suction cup, materials such as polyurethane, nitrile rubber, or vinyl-containing polymers can be considered for manufacturing the suction cup. Usually, to avoid scratching the surface of the product, it is best to choose suction cups with bellows made of nitrile rubber or silicone rubber. The suction cup material is made of nitrile rubber, which has high tensile strength, and is therefore widely used in various vacuum holding devices.

Rohm Workholding Fixture Overview

Vacuum suction cups are one of the actuators for vacuum equipment. The suction cup material is made of nitrile rubber, which has high tensile strength, and is therefore widely used in various vacuum holding devices, such as in construction, paper industry, printing, glass, and other industries, to perform tasks of holding and transporting thin and light items like glass and paper. Vacuum suction cups are also known as vacuum lifters and vacuum nozzles. Generally, using vacuum suction cups to grip products is the most economical method. Vacuum suction cups come in various types; rubber suction cups can operate at high temperatures, silicone rubber suction cups are very suitable for gripping products with rough surfaces, and polyurethane suction cups are highly durable. In addition, in actual production, if oil resistance is required for the suction cup, materials such as polyurethane, nitrile rubber, or vinyl-containing polymers can be considered for manufacturing the suction cup. Usually, to avoid scratching the surface of the product, it is best to choose suction cups with bellows made of nitrile rubber or silicone rubber.

Rohm Workholding Fixture Principles and Features

The structure of a flat vacuum suction cup consists of the suction cup and the suction cup clamp. First, connect the flat vacuum suction cup to vacuum equipment (such as a vacuum generator) via a pipe, then bring it into contact with the object to be lifted (such as glass, paper, etc.). Start the vacuum equipment to create negative pressure inside the suction cup, thereby securely holding the object, and begin transporting it. When the object reaches the destination, air is smoothly injected into the vacuum suction cup, changing the internal pressure from negative to zero or slightly positive, causing the suction cup to release the object, thus completing the lifting and transportation task. 1) High wear. Since it is generally made of rubber and directly contacts objects, it suffers from severe wear and rapid degradation. It is a pneumatic wearable part. Precisely because of this, it stands out significantly among many pneumatic components. 2) Easy to use. Regardless of the material of the object being sucked, as long as it can be sealed without air leakage, it can be used. Electromagnetic chucks cannot do this; they can only be used on steel, and cannot hold plates or objects made of other materials. 3) No pollution. Vacuum suction cups are particularly environmentally friendly, do not pollute the environment, and produce no light, heat, or electromagnetic interference. 4) Does not damage the workpiece. Since vacuum suction cups are made of rubber material, picking up or placing down workpieces will not cause any damage to them. Hook-type lifters and cable-type lifters cannot achieve this. In some industries, where requirements for workpiece surface quality are particularly strict, only vacuum suction cups can be used.

Rohm Workholding Fixture Classification

1) Base components: Such as square, rectangular, and circular base plates, used as fixture tooling tables. All five working faces of the worktable have grid-marked holes. The flatness, parallelism, and perpendicularity tolerances of these five faces, as well as the positional accuracy of the holes, are very high, ensuring sufficient positioning accuracy on the table and during combination with other modules. The dimensions of the base table can be chosen arbitrarily, and special sizes can be customized. If high precision is required after combining tables, guide rails can be used to connect them. 2) Support components: Including U type square boxes, L type square boxes, support angle irons, angular connection blocks, angle gauges, frame support seats, etc.; used for height positioning or platform expansion, and for positioning or clamping other accessories. These are components that position support elements such as shims, spacer plates, support plates, support blocks, and extension plates on the platform to ensure the workpiece meets certain height requirements during processing, mainly serving as supports at different heights. 3) Positioning components: Including positioning squares, positioning straight edges, planar angle squares, V type positioning components, eccentric circle stops, used to accurately adjust positioning location or height. These are components that precisely position the workpiece to ensure it meets certain dimensional accuracy requirements during processing; used to determine the relative positions between components, and between components and workpieces. 4) Adjustment components: Including: height adjusters, adjustment shims; Purpose: Components used to adjust position differences and gaps between components and workpieces. 5) Clamping components: Including: 90° spiral clamps, horizontal spiral clamps, 45° spiral clamps, vertical quick-action clamps, horizontal push-type quick-action clamps; Purpose: Components used to clamp the workpiece onto the platform or base elements to ensure it does not shift during processing. 6) Locking components: Including: quick-locking pins, countersunk quick-locking pins, countersunk locking pins, handle quick-locking pins, locating pins, magnetic connection locking pins, hex socket locking pins, hex head locking pins, magnetic pins; Purpose: Components used for positioning and locking between elements. 7) Assembly components: Including: 90 degree clamping angle sleeves, 45 degree clamping angle sleeves, parallel clamping angle sleeves, vertical clamping angle sleeves, standard support legs, swivel caster support legs with brakes, fixed support legs, frame-structure support seats, hydraulic lifting support seats, support rails; Purpose: Components acting on the connection or support between elements and other parts. 8) Other components: Including: retaining rings, grounding devices, spiral clamps, pipe clamps, lifting rings, cross-slot pressure pads, two-point clamping bridges, three-point clamping bridges, multi-purpose support templates, platform protective plates, tool trolleys; Purpose: Auxiliary components for the assembly of tooling elements. 9) Assembly tools: Including hex keys, oil stones, magnetic pliers, and other assembly tools.
