Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, specifically a chip scraper for machine tool guideways. Background Technology

[0002] In CNC machine tools, guideways are crucial functional components, enabling the linear movement of machine tool parts to process workpieces. During machining, chips are inevitably generated. Due to factors such as the cutting path and cutting speed, the movement trajectory of these chips is unpredictable. If chips enter the guideways, they will damage the machine tool, causing significant losses.

[0003] According to a public notice (No. CN216371077U), a cover plate for scraping chips from CNC machine tool guideways that is easy to disassemble and assemble, the fixing block in the above application is provided with a threaded groove. The fixing block is installed on the inner wall of the cover plate by fixing screws. This not only facilitates the quick and convenient installation, use, disassembly and maintenance of the device and machine tool, but also facilitates the regular maintenance and replacement of the chip scraping component by the staff. The structure is simple and easy to use.

[0004] However, in actual use, when the vertical cleaning brush is used to clean the surface of the guide rail, some of the debris adheres to the brush when it comes into contact with the debris. This causes the debris to come into contact with the surface of the guide rail again during subsequent cleaning, and the debris is easy to fall off and stick to the curved surface of the guide rail, affecting the cleaning effect. In view of this, we propose a scraper for machine tool guide rails. Utility Model Content

[0005] The purpose of this utility model is to provide a scraper for machine tool guideways to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a scraper for machine tool guideways, comprising a guideway, a slider disposed on the surface of the guideway, a cleaning mechanism disposed on the surface of the guideway, and an auxiliary mechanism disposed on the surface of the guideway, the cleaning mechanism comprising:

[0007] A scraper plate is connected to the surface of the slider by screw threads. An air blower is fixedly installed on the upper surface of the slider, and an air blowing pipe is fixedly connected to the surface of the air blower.

[0008] A docking groove is formed on the side wall of the scraper plate, and the surface of the scraper plate is provided with a groove.

[0009] Preferably, the auxiliary mechanism includes a mounting block, which is fixedly mounted on the side wall of the scraper. A limit block is fixedly mounted on the surface of the mounting block, and a limit rod is fixedly mounted on the side wall of the limit block. A rubber block is provided inside the mounting block, and cleaning bristles are fixedly mounted on the side wall of the rubber block.

[0010] Preferably, the surface of the mounting block is provided with a storage groove, the shape of which is adapted to the shape of the rubber block, so as to facilitate the placement of the rubber block.

[0011] Preferably, a control block is fixedly installed on the surface of the rubber block, and the limiting rod can pass through the control block to limit and position the rubber block.

[0012] Preferably, the scraping surface of the groove is inclined, providing space for the scraper plate to deform locally during scraping, thereby reducing the wear of the scraper plate. The inclined scraping surface of the scraper plate reduces wear while improving scraping ability.

[0013] Preferably, the surface of the docking groove is provided with a docking hole, and the surface of the slider is provided with a threaded hole, so that the screw passes through the docking groove and is threadedly connected to the threaded hole of the slider to install the scraper.

[0014] Preferably, the rubber block is trapezoidal in shape, and the shape of the rubber block matches the shape of the groove, so that the rubber block can move inside the groove.

[0015] Preferably, the air blowing pipe has an air jet opening on its arc surface, and the air blowing pipe is inverted U-shaped to facilitate air blowing by the air blower, so that the air blowing pipe blows air onto the surface of the guide rail, causing the waste debris to be blown off the arc surface of the guide rail.

[0016] Compared with the prior art, this utility model provides a chip scraper for machine tool guideways, which has the following characteristics:

[0017] Beneficial effects:

[0018] 1. The machine tool guide rail uses a scraper plate with a cleaning mechanism. The slider moves on the guide rail, and the air blower blows air onto the surface of the guide rail, causing the waste chips to be blown up from the arc surface of the guide rail. This, combined with the scraper plate, scrapes off the waste chips from the guide rail. The scraping surface of the groove is inclined, providing space for the scraper plate to deform locally during scraping, reducing the wear of the scraper plate. The inclined scraping surface of the scraper plate reduces wear while improving scraping ability. At the same time, the groove can collect waste chips, facilitating subsequent cleaning and ensuring that the waste chips are cleaned and prevented from adhering to the surface of the guide rail again.

[0019] 2. The scraper plate for the machine tool guide rail is equipped with an auxiliary mechanism to control the movement of the rubber block, so that the rubber block is disengaged from the limit rod. Together with the cleaning bristles, it cleans the waste chips inside the groove on the scraper plate. The flexibility of the rubber block allows it to easily fit into the inside of the groove, ensuring the cleaning effect of the waste chips inside the groove and promoting the subsequent cleaning effect of the scraper plate.

[0025] like Figures 1-4 As shown, this utility model provides a technical solution: a scraper for machine tool guideways, including a guideway 1, a slider 2 provided on the surface of the guideway 1, a cleaning mechanism 3 provided on the surface of the guideway 1, and an auxiliary mechanism 4 provided on the surface of the guideway 1. The cleaning mechanism 3 includes a scraper 301, an air blower 302, an air pipe 303, a docking groove 304, and a groove 305.

[0026] In one embodiment of this utility model, the scraper plate 301 is connected to the surface of the slider 2 by screw thread, the upper surface of the slider 2 is fixedly installed with the air blower 302, the surface of the air blower 302 is fixedly connected with the air blowing pipe 303, the docking groove 304 is opened on the side wall of the scraper plate 301, and the surface of the scraper plate 301 is provided with the groove 305.

[0027] In addition, the auxiliary mechanism 4 includes a mounting block 401, which is fixedly mounted on the side wall of the scraper plate 301. A limiting block 402 is fixedly mounted on the surface of the mounting block 401, and a limiting rod 403 is fixedly mounted on the side wall of the limiting block 402. A rubber block 404 is provided inside the mounting block 401, and a cleaning bristle 405 is fixedly mounted on the side wall of the rubber block 404. A storage groove is provided on the surface of the mounting block 401, and the shape of the storage groove is adapted to the shape of the rubber block 404 to facilitate the placement of the rubber block 404. The scraping surface of the scraper plate 301 is adapted to the shape of the guide rail 1.

[0028] In this embodiment of the invention, a control block is fixedly mounted on the surface of the rubber block 404, and a limiting rod 403 can pass through the control block to limit and position the rubber block 404. The scraping surface of the groove 305 is inclined, providing space for the scraper plate 301 to undergo local deformation during scraping, thus reducing the wear of the scraper plate 301. The inclined surface of the scraper plate 301 reduces wear while improving scraping ability. A mating hole is provided on the surface of the mating groove 304, and a threaded hole is provided on the surface of the slider 2. A screw passes through the mating groove 304 and is threaded into the threaded hole of the slider 2 to install the scraper plate 301. The rubber block 404 is trapezoidal in shape and its shape matches the shape of the groove 305, allowing the rubber block 404 to move inside the groove 305. The air pipe 303 has an air nozzle on its arc surface and is inverted U-shaped, which facilitates the air blower 302 to blow air onto the surface of the guide rail 1, causing the waste to be blown off the arc surface of the guide rail 1.

[0029] In this utility model, during use, the slider 2 moves on the guide rail 1, the air blower 302 blows air, and the air blowing pipe 303 blows air onto the surface of the guide rail 1, causing the waste to be blown up from the arc surface of the guide rail 1. Then, in conjunction with the setting of the scraper plate 301, the waste on the guide rail 1 is scraped off. The scraping surface of the groove 305 is inclined, which gives the scraper plate 301 space for local deformation during scraping, reducing the wear of the scraper plate 301. The scraping surface of the scraper plate 301 is set as an inclined surface, which reduces wear and improves scraping ability. At the same time, the groove 305 can collect waste, which is convenient for subsequent cleaning and ensures that the waste is cleaned and does not adhere to the surface of the guide rail 1 again.

[0030] Furthermore, by controlling the movement of the rubber block 404, the rubber block 404 is disengaged from the limiting rod 403, and works with the cleaning bristles 405 to clean the waste inside the groove 305 on the scraper plate 301. The flexibility of the rubber block 404 allows it to easily fit into the inside of the groove 305 and move, ensuring the cleaning effect of the waste inside the groove 305 and promoting the subsequent cleaning effect of the scraper plate 301.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
