Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1-6, a roller guide shaft structure comprises a guide roller 1, shaft heads at two ends of the guide roller 1 are respectively provided with a bearing seat 2, each bearing seat 2 comprises an upper base 3 and a lower base 4 which are correspondingly buckled with each other, and the upper base 3 is provided with a first semicircular groove 5 for accommodating a bearing; the both sides of upper pedestal 3 and lower base 4 all are equipped with the fixed ear 6 that is used for screw locking, and upper pedestal 3 has and corresponds the cooperation with the first semicircular groove 5 of lower base 4 for the second semicircular groove 7 of fixed arrangement bearing.

The internal surface of first semicircular groove 5 is equipped with a plurality of outstanding racks 8, and the interior bottom of lower base 4 is equipped with elasticity kicking block 9, and elasticity kicking block 9 is inlayed on second semicircular groove 7 of lower base 4 to the top face protrusion of elasticity kicking block 9 is equipped with a plurality of outstanding racks 8 in the surface of second semicircular groove 7, the upper surface of elasticity kicking block 9.

The racks 8 are arranged in a slash shape; two sides of the upper base 3 are provided with oil injection ports 10 which are inclined downwards, the lower end openings of the oil injection ports 10 face to the bearings in the bearing seats 2 and are provided with filter screens 11, and the upper end openings of the oil injection ports 10 are provided with sealing covers 12. The cover 12 is screwed to the upper base 3.

The filter screen 11 is a stainless steel perforated filter screen 11. The filter screen 11 with the holes made of stainless steel not only has a good buffering effect, but also has a long service life while ensuring the filtering effect.

As an embodiment, the elastic top block 8 includes a top block 13, a plurality of compression springs are disposed at a lower end of the

top block

13, and 14 the top block 13 is slidably connected to a side wall of the lower base 4, such as a sliding groove structure.

In order to avoid abrasion of the shaft head, the upper end edge of the ejector block is chamfered with an arc angle.

The racks 8 are arranged in an S-shaped sequence, and the area of contact with the bearing can be obviously increased through the racks 8 arranged in the S-shaped sequence, so that the fixing strength is effectively improved, and the shaft heads of the guide rollers are not easy to loosen after long-time continuous operation.
