Abstract
The linear guide with improved assemblability according to the present invention has a retainer having a laminated structure, and when assembled into a block, warping due to a block is prevented, and insertion of a rolling member is facilitated, thereby improving assembling performance of the linear guide.
Description
BACKGROUND OF THE
Generally, the linear guide apparatus comprises a guide rail, a guide block, and a plurality of balls interposed between the guide rail and the guide block. On the left and right side surfaces of the guide rail, rolling grooves for rolling balls are formed. The guide block includes a main body having another transmission groove corresponding to the transmission groove, a pair of frames coupled to the main body, an end cap coupled to the front and rear of the frame, and an end seal .
Korean Patent Registration No. 10-0713151 (Apr. 24, 2007), which is filed in the prior art, discloses a linear guide device capable of securing the rigidity of a slider and reducing the number of parts. FIG. 1 is a perspective view showing a conventional linear guide device, and FIG. 2 is an exploded perspective view showing a conventional linear guide device.
1 and 2, the linear guide device includes a

The
There are various types of linear guide apparatuses other than the linear guide apparatuses disclosed in Korean Patent Registration No. 10-0713151 (Apr. 24, 2007), and the grooves forming the passage of the balls interposed between the blocks and the rails are arranged in one or two rows And the like. The retainer may be provided on both sides in the axial direction of the block, which is the return portion of the ball. The end seal that performs the sealing function is made of rubber material, and is separately separated into the side seal and the inner seal, and each acts as a hermetic seal.
However, in the conventional linear guide device, when the end seal assembling portion is integrally provided with the end seal assembling portion integrally serving as a retainer, structural distortion occurs due to distortion of the main body and insertion of the rolling member is not easy, There is a problem that the assemblability is poor.
In order to solve such conventional problems, the present invention provides a linear guide having a multilayered structure to prevent the retainer from being deformed by a block, and to improve the ease of assembling the rolling member .
According to another aspect of the present invention, there is provided an image forming apparatus including a guide rail, a guide block movably provided along the guide rail, and a plurality of rolling elements interposed between the guide rail and the guide block, The guide block includes a block, a seal member, and a retainer provided on both sides in the axial direction of the block to form a circulation passage of the rolling member; The block is formed in an " inverted U " shape having downwardly extending portions on both sides, a downwardly extending portion is formed in the downwardly extending portion thereof with a uni-axial right hole penetrating therethrough in the axial direction, A load-receiving groove extending in the direction of the sheet;
The retainer includes a first retainer member having a first U-turn hole and a second U-turn hole formed in an axial direction and being axially penetrated, and a second retainer member covering the first U-turn hole and the second U- And a second retainer member formed with a U-shaped groove and laminated to the first retainer member; Wherein the second retainer member is provided with a protrusion protruding in a direction toward the first retainer member;
Wherein the first retainer member is formed with an extending groove side surface surrounding the first U turn hole and the second U turn hole while forming a protruding surface in a direction toward the second retainer member; Wherein the protruding portion is inserted into the side surface of the extending groove and the end of the protruding portion is in contact with the protruding surface so that the first retainer member and the second retainer member are laminated and joined together.
In this case, the protruding jaw surface has a protruding portion between the second U-turn hole and the first U-turn hole, which is more protruded than the axially outer surface of the first retainer member, The projection has a concave portion that is more concave than the axial inner surface of the second retainer member, thereby forming a groove surface;
And the connecting jaw face is provided so as to face the concave grooved surface of the protruding portion.
The linear guide with improved assemblability according to the present invention has a retainer having a laminated structure, and when assembled into a block, warping due to a block is prevented, and insertion of a rolling member is facilitated, thereby improving assembling performance of the linear guide.
