TW202126925A - Lubricating oil channel for slide block for conveniently and flexibly selecting at least one oil injection hole to perform oil injection - Google Patents

Abstract

Provided is a lubricating oil channel for a slide block, which includes a slide block and two end covers. The slide block is sleeved on a guide rail, so that the slide block may perform a linear movement on the guide rail by using rolling elements inside the slide block as a medium. The end covers are arranged at two opposite ends of the slide block, so that the rolling elements may perform a reciprocating cyclic displacement through a circulating channel inside the end cover. The end cover has an inner end, an outer end and two edges. An oil passage is provided above the inner end, and each of both sides of the oil passage is connected to the circulating channel by a downward bending of a first drainage channel. The center of the outer end of the end cover is provided with a first oil injection hole that penetrates the oil passage. Each of the two edges is provided with a second oil injection hole, and a second drainage channel penetrates the tail end of the second oil injection hole, so that the downward bending of the second drainage channel can be used for connection to the oil passage.

Description

Slide oil channel

The present invention relates to a "slider lubricating oil passage", in particular to a convenient and flexible selection of at least one oil injection hole as an oil-filling slider lubricating oil passage.

Press, the linear guide system is subdivided into two parts: a guide rail and a slider. The slider uses its internal rolling elements (steel balls) as a medium to run linearly on the guide rail. The slider includes a slider body, Rolling elements, end caps, and other components that can ensure the rolling elements of the rolling elements, when the slider moves linearly on the guide rail, a certain temperature rise and wear will occur, which will affect the use of the linear guide rail Accuracy and longevity. Therefore, the conventional method will provide an oil injection hole in the center of the end face of the end cover, so that the oil injection hole is used to regularly add lubricating oil to the slider for maintenance. However, because of the single point Lubrication is likely to be restricted due to the difference in equipment space or the installation direction of the linear guide, so that the linear guide cannot be filled in a more convenient way, or cannot be lubricated at all, so it is necessary to improve and innovate.

Therefore, how to develop a slider lubricating channel structure that can be filled with oil from any oil filling port according to the convenience of the equipment space or installation direction is the problem that the inventor wants to improve.

Therefore, the inventor of the present invention is in view of this, and is thinking about the idea of creation, and then based on years of experience Experiments were designed, after various discussions and sample tests, and many amendments and improvements, the present invention was introduced.

The lubricating oil channel of the slider of the present invention includes a slider and two end caps. The slider is set on a guide rail, so that the slider can use the rolling elements in the slider as a medium to be used on the guide rail. Straight line operation, the end caps are arranged at two opposite ends of the sliding block, so that the rolling elements can make reciprocating cyclic displacements through the circulating channels in the end caps, wherein the end caps have an inner side, One outer end and two sides, an oil passage is provided above the inner end, both sides of the oil passage are connected to the circulation channel by a downward bend of a first approach, and the center of the outer end of the end cover is provided There is a first oil injection hole penetrating into the oil passage, a second oil injection hole is provided on each of the two sides, and a second approach path is penetrated at the end of the second oil injection hole, so that the second approach path The downward turning point is connected with the oil passage, and the first oil injection hole and the two second oil injection holes are arranged at the same time, so that the user can choose from at least one of the oil injection holes according to actual needs and convenience. The hole is filled with oil smoothly to avoid the oil filling hole being blocked or the equipment space is insufficient, that is, the slider and rolling elements are difficult to be maintained, or the oil cannot be filled and lubricated at all; thereby, it can form the lubricating oil passage of the slider .

The slider lubricating channel of the present invention, because the end cover is provided with a first oil injection hole and two The second oil injection hole allows the user to conveniently and flexibly choose to inject oil from at least one of the oil injection holes according to the equipment space plan or the installation direction of the guide rail, so that the injected lubricating oil can use the oil passage and the second oil channel. The connection of the first approach and the second approach is conducted, and evenly and fully transports to the two circulation channels. In this way, no single oil injection hole is shielded or the equipment space is insufficient, which results in the slider The phenomenon that it is difficult to be maintained or cannot be lubricated at all, so that the slider and rolling elements can always obtain sufficient and stable lubrication.
