Description

Technical Field

[0001] This utility model relates to the field of linear guide technology, and in particular to a novel low-cost and high-maintenance linear guide device. Background Technology

[0002] Linear guides are widely used devices in industrial machinery, providing precise movement and positioning between mechanical components. They primarily transmit loads through the reciprocating rolling of rollers. These rollers are mounted in roller grooves within a slider via roller cages. End caps are assembled at both axial ends of the slider to seal them and to house grease fittings for adding lubricant. The end caps also serve an auxiliary function: confining the rollers to prevent them from detaching from the slider's axial ends. Current technology typically involves machining a groove on the slider to confine the rollers. However, frequent collisions between the rollers and this groove during operation can damage the end caps over time, necessitating replacement and increasing maintenance time and costs. Therefore, a new, low-cost, and highly efficient linear guide device is needed to address these technical problems. Utility Model Content

[0003] The purpose of this invention is to solve the technical problem that existing rollers frequently collide with the groove during operation, which causes damage to the end cap over time, requiring the replacement of the end cap, increasing maintenance time and costs. The invention provides a new type of low-cost, high-efficiency linear guide device to solve the above-mentioned technical problems.

[0004] A novel, low-cost, and highly efficient linear guide device is characterized by comprising a linear guide, a slider, rollers, a roller retainer, a roller guide block, a roller limiting block, a roller protective tube, end caps, and a sealing dustproof sheet. The linear guide has two rows of roller grooves on both sides of its top. The slider has a sleeve groove at its bottom, with two rows of roller grooves on both sides of the sleeve groove. The shape of the sleeve groove matches the linear guide. The roller grooves and roller slots correspond one-to-one. The axial end of the slider has four rows of roller channels, each corresponding to a roller slot. The rollers are assembled within the roller slots via roller retainers. The roller protective tube is assembled within the roller channels. The roller guide block is a U-shaped roller guide block, divided into roller guide block A and roller guide block B. The roller guide block is assembled on the outside of roller guide block B. One end of the roller guide block is fitted with the roller groove, and the other end is fitted with the roller channel. The roller protective tube is a plastic tube and is assembled inside the roller channel. The end cap is assembled on both axial ends of the slider. The sealing dustproof sheet is assembled on the outside of the end cap. The end cap has a groove, a roller groove, and a cylindrical slot. The shape of the groove matches the roller limiting block. The roller limiting block is assembled inside the groove. The end cap is initially assembled on the slider by snapping it onto the roller channel through the cylindrical slot. The roller groove, roller channel, and roller channel form a complete roller running raceway. The roller groove and the roller running raceway correspond and cooperate with each other. The roller limiting block has a roller baffle, and the side of the roller baffle that contacts the roller is designed with an arc.

[0005] Furthermore, the roller grooves have four rows, consisting of two rows of upper roller grooves and two rows of lower roller grooves; the roller channels have four rows, consisting of two rows of upper roller channels and two rows of lower roller channels.

[0006] Furthermore, the roller protective tube is a hollow circular protective tube.

[0007] Furthermore, the sealing dustproof sheet is a metal sealing dustproof sheet.

[0008] Furthermore, the end cap and roller limiting block are made of plastic.

[0009] Furthermore, one end of the B roller guide block is fitted with the upper roller channel, and the other end is fitted with the lower roller groove; one end of the A roller guide block is fitted with the lower roller channel, and the other end is fitted with the upper roller groove.

[0010] Compared with the prior art, the advantages of this utility model include: the roller limiting structure and the end cover are designed as separate structures, and a groove for installing the roller limiting block is machined on the end cover. The roller limiting block is installed in the groove and will not protrude from the end cover, thus not affecting the normal installation of the end cover. The roller limiting block is provided with an arc-shaped roller baffle to restrict the roller. During maintenance, only the roller limiting block needs to be replaced, and the entire end cover does not need to be replaced, saving maintenance time and maintenance costs.
