The terminology used in the description herein is for describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0019] The guide rail protective cover provided by the application comprises a plurality of protective covers and sealing structures arranged between adjacent protective covers; the sealing structure comprises an outer scraping strip arranged in the gap between adjacent protective covers, a flow guide groove arranged at one end of each protective cover, and a sealing strip arranged at the free end of one side wall of the flow guide groove; the flow guide groove is used for guiding out cutting fluid infiltrated from the outer scraping strip; and one end of the sealing strip away from the flow guide groove is in abutment with the inner wall of another adjacent protective cover.

[0020] The guide rail protective cover provided by the application comprises a plurality of protective covers and sealing structures arranged between adjacent protective covers; the sealing structure comprises an outer scraping strip arranged in the gap between adjacent protective covers, a flow guide groove arranged at one end of each protective cover, and a sealing strip arranged at the free end of one side wall of the flow guide groove; the flow guide groove is used for guiding out cutting fluid infiltrated from the outer scraping strip; and one end of the sealing strip away from the flow guide groove is in abutment with the inner wall of another adjacent protective cover.

[0021] The guide rail protective cover provided by the application comprises a plurality of protective covers and sealing structures arranged between adjacent protective covers; the sealing structure comprises an outer scraping strip arranged in the gap between adjacent protective covers, a flow guide groove arranged at one end of each protective cover, and a sealing strip arranged at the free end of one side wall of the flow guide groove; the flow guide groove is used for guiding out cutting fluid infiltrated from the outer scraping strip; and one end of the sealing strip away from the flow guide groove is in abutment with the inner wall of another adjacent protective cover.

[0022] In one embodiment, as Figures 1-4As shown, a guide rail protective cover includes several sections of cover 1 and a sealing structure 2 disposed between each pair of adjacent cover 1. The sections of cover 1 are connected by a scissor telescopic mechanism, which extends or retracts the guide rail cover. The top of each section of cover 1 is triangular, meaning each cover has two ramps at its top, with the connection point of the two ramps protruding upwards. The sealing structure 2 includes an outer scraper strip 21 disposed within the gap between each pair of adjacent cover 1, a guide groove 22 disposed at one end of each cover 1, and a sealing strip 23 disposed at the free end of one sidewall of the guide groove 22. The guide groove 22 is used to drain cutting fluid that seeps in from the outer scraper strip 21. The end of the sealing strip 23 away from the guide groove 22 abuts against the inner wall of another adjacent cover 1. The outer scraper 21 is located near the tail of the guide rail protective cover, and the guide groove 22 is located near the head of the guide rail protective cover. When the guide rail protective cover retracts, the outer scraper 21 scrapes off the chips and cutting fluid on each cover 1, preventing them from entering the interior of the cover through the gaps between the covers. The scraped cutting fluid flows out of the machine tool along the slope at the top of each cover. Some cutting fluid that seeps into the outer scraper 21 is discharged through the guide groove 22. In addition, the sealing strip 23 at the upper end of the guide groove 22 scrapes off the cutting fluid adhering to the inner wall of another adjacent cover 1 and drops it into the guide groove 22 for discharge, thereby preventing the cutting fluid from entering the interior of the cover.

[0023] In another embodiment, such as Figure 3 As shown, the outer scraper strip 21 includes a mounting base 211 and a scraper tongue 212. The mounting base 211 is disposed between each pair of adjacent protective covers 1, and the scraper tongue 212 is disposed at the outer end of the mounting base 211. The mounting base 211 is made of metal, and the scraper tongue 212 is made of rubber. The mounting base 211 is fixed in the gap between each pair of adjacent protective covers by riveting or pressure welding, and is sealed by the scraper tongue 212. During the operation of the guide rail protective cover, the scraper tongue 212 can scrape out the cutting fluid and debris on the surface of the protective cover, and the cutting fluid will flow out of the protective cover along the slope at the top of the protective cover. That is, the outer scraper strip 21 removes part of the cutting fluid and debris, preventing the cutting fluid from entering the interior of the protective cover through the gap between the two protective covers.

[0024] In another embodiment, such as Figure 3As shown, the sealing strip 23 comprises a hollow cylinder portion 231 and a tongue portion 232 abutting against the inner wall of another adjacent shield 1; the sealing strip 23 further comprises a clamping portion 233, the cylinder portion 232 is located between the clamping portion 233 and the tongue portion 232, and the clamping portion 233 is clamped at the free end of one side wall of the flow guide groove 21. The sealing strip 23 is made of rubber material, by arranging the compressible hollow cylinder portion, it is ensured that the tongue portion 232 always abuts against the inner wall of the shield 1, so that the sealing strip 23 can be completely sealed, preventing the cutting fluid from entering the inside of the guide rail shield, and achieving 100% sealing effect.

[0025] In another embodiment, as shown in Figure 3 As shown, the end of the tongue portion 232 is directed towards the flow guide groove 22, so that the cutting fluid adhering to the inner wall of the shield is completely scraped off by the tongue portion 232.

[0026] The technical features of the above-mentioned embodiments can be combined arbitrarily, in order to make the description simple, all possible combinations of the technical features in the above-mentioned embodiments are not described, however, as long as the combination of the technical features does not exist contradictory, it should be considered that it is within the scope of the present application.

[0027] The above-mentioned embodiments only express several implementation manners of the present application, the description is more specific and detailed, but it should not be understood as the limitation of the scope of the present application. It should be pointed out that, for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the present application patent should be subject to the appended claims.
