Description

Technical Field

[0001] This utility model relates to the field of machine tool accessories technology, specifically an adjustable machine tool guide rail chip scraping structure. Background Technology

[0002] Utility model patent CN222371047U discloses a machine tool guide rail scraping structure. This structure includes a guide rail and a wall plate, with the wall plate positioned on the outer side of the guide rail. The guide rail is equipped with a guide rail scraper plate that can move along its length, and the scraper plate has a scraper tongue that abuts against the outer surface of the guide rail. The wall plate, near the guide rail, is equipped with a wall plate scraper plate that can move along its length, and the scraper tongue has a scraper tongue that abuts against the inner surface of the wall plate. This machine tool guide rail scraping structure solves the problems of complex installation and large space occupation of protective covers, and has the advantages of simple structure, no maintenance required, and low cost.

[0003] The current machine tool guideway scraping structure relies solely on the guideway scraper tongue and lower scraper tongue to directly contact the guideway and base support plate for scraping. After prolonged use, debris easily gets mixed into the gap between the guideway and the guideway scraper tongue, leading to a decrease in the fit between the scraper tongue and the guideway, which in turn affects the scraping effect. Therefore, we propose an adjustable machine tool guideway scraping structure. Utility Model Content

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-5 An adjustable machine tool guide rail scraping structure includes a guide rail 100, a slide block 110 slidably connected to the guide rail 100, and scraping mechanisms 200 installed at the front and rear ends of the slide block 110. The slide block 110 can slide stably along the guide rail 100, providing a mounting base for the scraping mechanism 200 and driving it to move synchronously, ensuring that the scraping operation covers different positions of the guide rail 100 as the slide block 110 moves. The scraping mechanisms 200 on the front and rear sides can scrape the areas in front of and behind the position passed by the slide block 110 when it moves, improving the comprehensiveness of scraping. The scraping mechanism 200 includes a fixed frame assembly 210 fixedly connected to the slide 110, two side cleaning assemblies 220 installed in the fixed frame assembly 210 and respectively distributed on the left and right sides of the guide rail 100, and a top cleaning assembly 230 installed in the fixed frame assembly 210 and located above the guide rail 100. The side cleaning assemblies 220 and the top cleaning assembly 230 can be used to clean the debris on the sides and top of the guide rail 100 in a targeted manner, ensuring the cleanliness of the outer periphery of the guide rail 100.

[0033] like Figure 2 and Figure 3As shown, in this utility model, the fixing bracket assembly 210 includes two fixing plates 211 distributed along the axial direction of the guide rail 100. The bottom of the fixing plate 211 is provided with a groove, through which the guide rail 100 passes. The groove provides a passage for the guide rail 100 to pass through, ensuring the relative positional relationship between the fixing plate 211 and the guide rail 100 and avoiding interference between the two. The groove wall is provided with a slot 2111, in which a scraper 212 is embedded. The scraper 212 is embedded in the slot 2111 and is embedded in the bottom of the fixing plate 211. The slot 2111 provides installation space for the scraper 212, which facilitates the positioning and installation of the scraper 212. This embedding method facilitates the installation and replacement of the scraper 212, while ensuring that the scraper 212 is not easily dislodged during operation. The scraper 212 is sleeved on the outside of the guide rail 100. The scraper 212 is used to perform preliminary cleaning of the debris adhering to the guide rail 100. The sleeved arrangement allows the scraper 212 to fully contact the outer surface of the guide rail 100, improving the effect of preliminary cleaning.

[0034] like Figures 2-4 As shown, specifically, the side cleaning assembly 220 is used to clean the debris adhering to the side end of the guide rail 100 again. The side cleaning assembly 220 includes a vertical cleaning sleeve 221 with bristles on its outer surface and a first motor 222. The first motor 222 is coaxially connected to the vertical cleaning sleeve 221. A pair of vertically distributed horizontal base plates 213 are fixed between the left and right ends of the two fixed plates 211. The vertical cleaning brush sleeve 221 is rotatably connected between the pair of horizontal base plates 213. The first motor 222 is fixed on the horizontal base plate 213 located at the top. The horizontal base plate 213 serves to install and fix the vertical cleaning brush sleeve 221 and the first motor 222. The vertical distribution provides a suitable installation height and rotation space for the vertical cleaning brush sleeve 221. The first motor 222 provides power for the rotation of the vertical cleaning brush sleeve 221, so that the first motor 222 can drive the vertical cleaning brush sleeve 221 to work continuously when working, so that the bristles on the outer surface of the vertical cleaning brush sleeve 221 can sweep the debris off the side of the guide rail 100 through contact friction.

[0035] like Figure 2 , Figure 3 and Figure 5As shown, the top cleaning assembly 230 is further used to clean the debris adhering to the top of the guide rail 100. The top cleaning assembly 230 includes a transverse cleaning sleeve 231 with bristles on its outer surface and a second motor 232. The bristles on the outer surface of the transverse cleaning sleeve 231 can contact the top of the guide rail 100. Its transverse arrangement allows it to adapt to the transverse surface of the top of the guide rail 100, effectively cleaning the debris. The second motor 232 is coaxially connected to the transverse cleaning sleeve 231. A pair of longitudinal seat plates 214 are fixed between the tops of the two fixed plates 211. The transverse cleaning sleeve 231 is rotatably connected between the two longitudinal seat plates 214. The rotatable connection allows the transverse cleaning sleeve 231 to rotate flexibly, thereby achieving continuous cleaning of the top of the guide rail 100. The second motor 232 is fixed to the outer end of one of the longitudinal seat plates 214. This installation position does not affect the rotation of the transverse cleaning sleeve 231 and ensures the stable operation of the second motor 232.

[0036] like Figure 1 and Figure 2 As shown, in addition, a pair of connecting plates 215 are fixed at the end face of the fixing plate 211 near the slide 110. The connecting plates 215 serve to connect the fixing plate 211 and the slide 110. The pair enhances the stability of the connection. The connecting plates 215 are fixedly connected to the slide 110 by bolts. The bolt connection method facilitates the installation and disassembly of the fixing frame assembly 210 and the slide 110, while ensuring the firmness of the connection.

[0037] like Figure 1 and Figure 2 As shown, it is worth noting that the top of the mounting bracket assembly 210 is covered with a cover 216. The front and rear ends of the cover 216 are fixed to two mounting plates 211 respectively. This fixing method allows the cover 216 to be stably covered on the top of the mounting bracket assembly 210, so that the cover 216 can protect the components on the top of the mounting bracket assembly 210 and prevent external debris from falling in and affecting the operation of each component.

[0038] It is worth noting that the first motor 222 and the second motor 232 involved in this utility model are both adjustable speed motors. The rotation speed of the vertical cleaning brush sleeve 221 and the horizontal cleaning brush sleeve 231 can be flexibly adjusted according to the amount and degree of adhesion of debris on the guide rail 100, so as to adapt to different scraping needs and realize the adjustability of the scraping process. This is a conventional technology and will not be described in detail in this utility model.

[0039] In this embodiment, the adjustable machine tool guide rail scraping structure operates as follows: First, the slide 110 slides along the guide rail 100, causing the scraping mechanism 200 to move synchronously. At this time, the scraper block 212 contacts the outer surface of the guide rail 100, performing preliminary cleaning of the debris on the guide rail 100. Then, the first motor 222 starts, driving the vertical cleaning brush sleeve 221 to rotate. The bristles on the outer surface of the vertical cleaning brush sleeve 221 clean the debris adhering to the side of the guide rail 100 again. Next, the second motor 232 starts, driving the horizontal cleaning brush sleeve 231 to rotate. The bristles on the outer surface of the horizontal cleaning brush sleeve 231 clean the debris adhering to the top of the guide rail 100 again. Finally, as the slide 110 continues to move, the scraping mechanism 200 performs the above cleaning operations on different positions of the guide rail 100.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
