Description

Technical Field

[0001] The utility model relates to the technical field of linear guide rail end covers, in particular to an end cover for a linear guide rail slider with long service life and high strength. Background Art

[0002] The primary function of a linear guide is guidance and support. It carries a moving part back and forth in a certain direction. This motion is relatively repetitive, requiring the guide rail and its accessories to be highly robust. During motion, the load on the guide rail generates significant friction, but the design and application of a spherical ball significantly reduces this friction.

[0003] The linear guide slider end cover seals and protects the two axial ends of the motor. At the same time, the lubricating oil of the linear guide device also enters the linear guide for lubrication through the oil nozzle installed on the linear guide slider end cover and the oil channel set in the slider end cover itself. An end cover is provided at both axial ends of the linear guide slider. The linear guide device is a device that requires reciprocating linear motion and has high precision requirements. Therefore, a high-strength end cover is required to seal and protect the axial ends of the slider, and an external protection structure that is easy to disassemble and assemble is required. However, the strength of the current linear guide slider end cover is not high. During long-term reciprocating high-precision operation, it is easy to be affected by impurities or external forces on the linear guide and crack or even break, allowing external impurities to enter and affect the operation accuracy of the slider. For this reason, we propose a long-life and high-strength linear guide slider end cover to solve the above technical problems. Utility Model Content

[0004] The purpose of the utility model is to solve the technical problem that the strength of the current linear guide slider end cover is not high and it is easily broken by impurities or external forces on the linear guide during long-term reciprocating high-precision operation. A long-life and high-strength linear guide slider end cover is provided to solve the above technical problem.

[0005] A long-life, high-strength linear guide slider end cover, characterized in that: it includes an end cover, the front of the end cover is provided with an oil inlet and a reinforcing rib, the left side and the right side of the end cover are each provided with a spare oil inlet, the back of the end cover is provided with a lubricating oil channel and a ball track, and a port for the guide rail to pass through is provided below the end cover, the shape of the port matches the outer contour of the guide rail, the oil inlet is communicated with the lubricating oil channel, the lubricating oil channel is communicated with the ball track, the reinforcing ribs are divided into horizontal reinforcing ribs and vertical reinforcing ribs, and the reinforcing ribs do not protrude from the front of the end cover.

[0006] As a preferred technical solution of the present invention, the lubricating oil channel is divided into a right lubricating oil channel and a left lubricating oil channel.

[0007] As an optimal technical solution of the present utility model, the transverse reinforcing ribs and the vertical reinforcing ribs are located in the upper part of the front face of the end cover. There is one transverse reinforcing rib and three vertical reinforcing ribs. The transverse reinforcing rib is located in the middle of the upper part of the front face of the end cover. The three reinforcing ribs divide the upper part of the front face of the end cover into four equal parts.

[0008] As a preferred technical solution of the present invention, the ball track is divided into a right ball track and a left ball track, and the left ball track and the right ball track are respectively located on the end cover surfaces on the left and right sides of the port.

[0009] As a preferred technical solution of the present invention, the transverse reinforcing ribs and the vertical reinforcing ribs form a grid surface on the upper portion of the end cover.

[0010] Compared with the prior art, the advantages of the present invention include: by arranging reinforcing ribs on the front side of the end cover, the reinforcing ribs are divided into horizontal reinforcing ribs and vertical reinforcing ribs, the horizontal reinforcing ribs and the vertical reinforcing ribs form a grid surface on the upper part of the end cover, thereby increasing the impact resistance of the end cover, and the strength of the end cover is enhanced. When following the back and forth movement of the slider, it will not crack or break. The slider can be better protected and sealed during the reciprocating movement of the slider, ensuring the operating accuracy of the slider. The reinforcing ribs do not protrude from the front side of the end cover, and the design of the reinforcing ribs will not affect the assembly of the end cover, and will not affect normal assembly and use.

When the linear guide is running, lubricating oil is added through the oil inlet, and the lubricating oil enters the lubricating oil channel through the oil inlet, and then enters the ball path through the lubricating oil channel to lubricate the balls. Specifically, the lubricating oil in the right lubricating channel lubricates the balls in the right ball path, and the lubricating oil in the left lubricating channel lubricates the balls in the left ball path, thereby reducing friction and extending service life.
