Description
Technical Field
The invention belongs to the technical field of linear guide rails, and particularly relates to a structure of a built-in oil tank of a linear guide rail.
Background
The linear guide rail motion device is used for guiding an object to move along a preset linear track. The linear guide motion device generally includes a linear guide and a slider mounted on the linear guide. The guided object is connected with the slide block so as to move linearly along the guide rail under the guidance of the slide block. The slider generally includes a slider main body and outer circulators located at both ends of the slider main body, a ball load passage for balls to roll is provided at one side of the slider main body facing the linear guide rail, a ball return passage penetrating through both ends of the slider main body is provided at the slider main body, the ball load passage and the ball return passage are connected through a ball transition passage provided at the outer circulators, thereby forming a ball circulation passage. A plurality of balls which are closely arranged and have the same size are arranged in the ball circulation channel. The slide block main body is contacted with the linear guide rail through the balls in the ball loading channel, and the balls roll in the ball circulation channel to move forwards along with the movement of the slide block.
The linear guide is a precise linear transmission assembly, and the lubrication state of the relative moving parts during operation has great influence on the service life of the linear guide. The traditional linear guide rail lubrication mode has two types, one is that the lubricating oil is periodically and individually supplemented, and the mode is inconvenient in lubrication maintenance. The other is that the forced lubrication system replenishes the lubricating oil in a timed and quantitative manner, which requires additional oil supply equipment and pipelines. In the prior art, an oil guide pipe is adopted to continuously supplement lubricating oil for a sliding block, a copper pipe oil way is required to be installed to connect an automatic or manual oil injection device, the lubricating oil is injected into the sliding block and is soaked in an operation system needing lubrication, the defects are unavoidable oil nozzle cost, oil pipe cost, automatic or manual oil injection device cost and manual assembly cost, the environmental protection problem also exists, because accurate lubrication cannot be carried out, lubricating oil must be soaked in a space to be lubricated in the whole sliding block, a lot of redundant oil is formed in the low-efficiency sliding block lubricating mode to overflow, and not only waste but also great environmental protection problems are caused. To avoid the inconvenience of machine maintenance and at the same time simplify the complexity of the machine installation, self-lubricating linear guides have come into play. The self-lubricating module mainly comprises a lubricating mechanism, a connector and a detachable oil tank. Current linear guide will reach from moist effect, must adopt the mode of optional additional oil tank, lets the manufacturer know when ordering and assemble good for the customer, perhaps the customer buys from lubricating block subassembly by oneself and uses after changing the dress. The hanging oil tank is additionally arranged at one end or two ends of the sliding block to supplement lubricating oil to the running system in the sliding block, so that the extra cost of replacing the self-lubricating module is increased, the hanging oil tank has a certain thickness size to generate volume to contain the lubricating oil, the most important stroke length is reduced, and the added value of the machine is reduced. The situation that the space of the equipment is limited is very unfavorable, and the development of related industries is limited, for example, the automation equipment generally needs to complete the correlation action in a relatively limited space, and the electronic semiconductor not only calculates the mobility per square meter area, but also requires the efficient use of the equipment under the minimization requirement of the product.

Because the end cover 2 exists, the space of the end cover 2 is only utilized, the stroke is not shortened, and the accommodating space of lubricating oil is expanded. When the needle cylinder fills the slider oil tank 3 with lubricating oil, the redundant lubricating oil can be diffused to the end cover oil tank 8 for auxiliary storage. The end cover oil tank 8 supplies oil through the oil path system 4, and the end cover oil tank 8 is arranged in the end cover 2, so that the distance from the lubricating oil to a lubricating position is shortest, and the lubricating efficiency is better.

As can be seen from the above structure, the flow of the lubricant from the slider oil tank 3 to the oil supply branch line 15 is facilitated.
Further, an oil absorption felt is embedded in the oil path system 4. With the above structure, the oil-absorbing felt can keep the lubricating oil stably supplied, and only when the load section 10 is short of the lubricating oil, the oil-absorbing felt supplies the lubricating oil to the load section 10.
Furthermore, the slider oil tank 3 is filled with oil from the side surface or the top surface or the end surface of the sliding body 1. According to the structure, the oil can be supplemented to the sliding block oil tank 3 from the side surface or the top surface or the end surface of the sliding body 1, and the stroke of the linear guide rail is not influenced.
