Problems solved by technology
However, when the ejector pin pushes out the retaining chain, the retaining chain will be pushed out in the form of bending and deformation due to interference problems. Since the retaining chain is elongated, it is easy to damage the retaining chain during the ejection process.

The invention relates to a roller holding chain, a roller holding chain manufacturing method and a linear moving mechanism. The roller holding chain is provided with a flat strip, the flat strip is axially provided with holes, a spacing block is arranged between each two holes, a hole surface is formed between two spacing blocks in a direction vertical to the flat strip, each spacing block is divided into an upper spacing block and a lower spacing block, one surface of each of the upper spacing block and the lower spacing block adjacent to the holes is a cladding surface, the cladding surface is partially a plane vertical to the axis of the flat strip, the residual cladding surface is an inclined baffle surface, the upper spacing block is in sliding connection with the plane of the lower spacing block, the inclined baffle surfaces of the upper and lower spacing blocks incline toward a position above the holes to hod a roller in the hole. The manufacturing method uses the inclined lateral opening and locking of a left die and a right die to realize injection molding in order to realize one-time molding of the complete roller holding chain.
Description
technical field [0001] The present invention relates to a roller retaining chain, a manufacturing method of the roller retaining chain, and a linear motion mechanism, in particular to a roller retaining chain in which a plurality of rollers extending axially in a row are retained, and the two are separated from each other. With a certain distance, the rollers keep the chain and the rollers and circulate in the circulation channel provided by the linear motion mechanism. Background technique [0002] The current linear motion mechanism has a moving part and an axially extending track part. The moving part and the track part each provide at least one row of corresponding tracks. There is a row of rolling bodies between the tracks that are in contact with the track and roll on the track. The moving part A return channel and two return channels are provided for each row of corresponding tracks. The return channel connects the return channel and the end surface entrance and exit ...
