Why tolerance compensation? In today's technology-oriented industry, time is becoming ever more important. Wherever there is mass production, cycle times across the entire process chain must be kept short and thus economical. Optimised assembly processes are the key to efficient production. The automotive industry is a very good example to illustrate the growing complexity of assembly processes. Subcontractors provide pre-prepared modules and the automobile manufacturing plant then only has to carry out the final assembly. In “modular construction”, standardised parts are assembled to complete...

Complex adjustment processes during assembly are time-consuming and thus generate high costs. Small tolerances require precision and, in consequence, more expensive production methods. Reject rates and quality assurance costs also increase. ■ Joining tolerances required for quick assembly ■ Individual tolerances stack up to become tolerance chains ■ Component stress is avoided ■ Allows for designs with redundant geometry ■ Easy adjustment processes produce precise gap widths The use of FLEXITOL® systems allows wider production tolerances so that production costs can be reduced. Conventional Employment...

FLEXITOL® technology Today we have manual and automatic tolerance compensation systems. Use of one or other depends on the field of application. When positioning a component in an assembly without any auxiliaries, then manual solutions are considered most appropriate. For a component spacing predefined by a preceding step, then we would rather recommend automatic solutions. However, manual and automatic tolerance compensation systems may also be combined. Manual tolerance compensation The tolerance compensation system is screwed into the receiving parts to a defined position. During screwing-in,...

Manual tolerance compensation system General functional principle The FLEXITOL® system (see figures) is supplied with a patented Böllhoff K’ in K’ thread.* This K’ in K’ thread is characterised by a unique thread profile. The different system variants are self-locking, selftapping, self-forming, adjustable and tolerance compensating and are directly screwed into a plastic component. Component tolerances can be compensated by varying the screw-in depth. After screwing-in, alignment to the second component is achieved. Prior to tightening the screw, radial tolerance compensation is also possible....

FLEXITOL® K’ in K’ example of the banjo screw For “banjo screws”, the function of the K’ in K’ thread is extremely important. The K’ in K’ thread creates its mounting thread into the existing plastic bore hole. Due to a resistance effect, the banjo screw can then only be screwed further in or out with a higher torque. We can offer different variants according to your requirements. Examples of banjo screws Manual Through hole and internal drive Metal insert for M 6 thread with external and internal drive Metal insert for M 6 thread and additional adapter for adjustment later Bolt thread and seal...

Automatic tolerance compensation system General functional principle Installation and riveting of the basic element (RIVKLE® blind rivet nut) into the receiving part. Screwing-in of the compensating element into the adjustment thread. Alignment of the mounting part. Upon screwing-in, the compensating element screws out and compensates eliminates the gap between the components. The aligned position is thus fixed. Examples of automatic tolerance compensation systems

FLEXITOL® metal FLEXITOL® metal was the first tolerance compensation system developed by Bollhoff. This two-component system is entirely made of metal and therefore highly wearresistant. Due to the small space required for installation in the separation gap, this solution may easily be integrated and even retrofitted into an existing installation space. ■ Highly wear-resistant metal adjustment element ■ Blind rivet nut available in different designs ■ Easy installation using proven blind riveting technology Automatic Standard program (excerpt) and technical data 0031 910 0011 0031 910 0011 Item...
