Slide rail assembly device and slide rail assembly method

Abstract

A slide rail assembly device comprises a sliding mechanism, a clamping mechanism, a pushing mechanism and an automatic feeding mechanism. The sliding mechanism comprises a longitudinal slide rail, a longitudinal slider, a transverse slide rail and a transverse slider. A sliding cylinder pulls a pulley plate to slide along the longitudinal slide rail. The clamping mechanism comprises a pair of guiding plates, and the two ends of each guiding plate are fixed to the transverse slider. Guiding through grooves of the guiding plates are obliquely and symmetrically formed in a pulley. Each guiding plate is provided with a clamping block and an inner rail profiling mold. The pulley drives the guiding plates along the guiding through grooves to slide along the transverse slide rail so that the inner rail profiling mold can be retracted inwards or expanded outwards. The pushing mechanism comprises positioning blocks on the clamping blocks and a pushing cylinder. Each clamping block comprises a bevel groove, a long groove and a feeding hole. A pushing plate is installed in each bevel groove. A pushing and pulling rod is arranged in each positioning block. The lower portion of each pushing and pulling rod is located in the corresponding long groove and a pushing and pulling groove of the corresponding pushing plate. The pushing cylinder can drive the pushing and pulling rods to move in the pushing and pulling grooves so that the pushing plates can move in the bevel grooves to reach a feeding groove, and a gap strip can be pushed into profiling grooves. The automatic feeding mechanism comprises automatic feeding units used for conveying holders, an inner rail, an outer rail and the gap strip.

Description

technical field [0001] The technology relates to the field of automobile manufacturing, in particular to a sliding rail assembly assembly device used on automobile seats. Background technique [0002] The slide rail part on the car seat is one of the key parts of the car seat. Whether the seat slide rail slides smoothly and reliably, whether the adjustment is flexible and convenient, and whether the structure is reasonable and safe is the basis of inspection. On the basis of this inspection, the seat slide Technological innovation, continuous improvement, cost reduction, and efficiency enhancement of rails are the key components that engineers and technicians in the field of automobile manufacturing pay attention to. [0003] The characteristic of the traditional slide rail is that before assembly, only one end of the inner rail and the outer rail has a steel ball (or cage) stop point at most. During assembly, the inner rail and the outer rail are generally combined first, a...

Problems solved by technology

[0005] The application of the new structure of the new slide rail will inevitably involve a series of innovations in production technology, among which the assembly of the new slide rail assembly is the key link, and the corresponding cages are placed in sequence and accurately on the corresponding slideways of the inner rail and the outer rail Spacers and gaps are the core technology. The assembly method of traditional steel balls plus gaps or a single whole cage cannot meet the needs of new slide rails. To solve the mechanization and automation of new slide rail assembly, there must be corresponding technical solutions. and implementation method
