Description

Technical Field

[0001] This utility model relates to the field of machine tool accessories technology, and in particular to a dustproof and chip-proof protection structure for machine tool guideways. Background Technology

[0002] Machine tools are the basic equipment for modern machining, such as lathes, milling machines, and grinding machines. During their operation, the worktable or tool post needs to reciprocate along a precision guide mechanism. The accuracy and stability of the guide mechanism directly affect the machining quality of the workpiece.

[0003] During metal cutting or grinding processes, a large amount of metal shavings, dust, and splashed cutting fluid are inevitably generated. These machining wastes can easily scatter and accumulate on the exposed guideway surfaces of the machine tool.

[0004] Once these dust and debris enter the gap between the guide rail and the slider, they will drastically increase the frictional resistance, causing scratches and wear on the guide rail surface. In severe cases, they may even cause the slider to jam. This not only reduces the machining accuracy of the machine tool, but also greatly shortens the service life of the guide rail mechanism and increases the maintenance cost of the equipment.

[0005] To address the aforementioned problems, existing technologies typically employ telescopic protective covers to shield the guide rails. However, the cleaning of these covers during expansion and contraction is often overlooked. When the cover retracts, debris and oil accumulated on its outer wall are carried into the folding gaps. Over time, this accumulation not only wears down the cover itself, causing seal failure, but also risks these accumulated contaminants eventually falling onto the guide rails, failing to achieve thorough dust and chip protection. Therefore, this invention proposes a dust and chip protection structure for machine tool guide rails to overcome the shortcomings of existing technologies. Utility Model Content

[0006] To overcome the above deficiencies, this utility model provides a dust and chip protection structure for machine tool guideways, aiming to improve the problem that some existing dust and chip protection structures for machine tool guideways lack effective shielding of the guideway mechanism and are easily contaminated by dust and debris.

[0007] This utility model provides a dust and chip protection structure for machine tool guideways, comprising: a worktable, a mounting block disposed on the worktable, and a guideway mechanism mounted on the mounting block; the guideway mechanism includes a base plate fixedly connected to the mounting block, a slide rail fixedly connected to the base plate, a slider slidably connected to the slide rail, and a mounting platform fixedly connected to the top of the slider; the structure also includes a protective cover and a connecting assembly; wherein, the connecting assembly includes a scraper plate and a limiting plate; and, the protective cover is disposed on both sides of the slider and moves synchronously with the slider, the limiting plate is disposed at one end of the protective cover and is used to interlock with adjacent protective covers when the protective cover extends, and the scraper plate is fixed to the other end of the protective cover and is used to scrape impurities on the outer wall of adjacent protective covers when the protective cover retracts.

[0008] Preferably, the mounting block and the worktable are detachably connected by a locking mechanism. The locking mechanism includes a limiting ring set on the inner wall of the worktable, a spring sleeved on the outer wall of the limiting ring, the spring abutting against the top plate, a sliding column fixedly connected to the top plate, and a locking ball abutting against the other side of the top plate. This structural design enables quick assembly and disassembly of the mounting block and facilitates maintenance.

[0009] Preferably, as a specific implementation of the above-mentioned locking mechanism, the outer wall of the mounting block is used to squeeze the locking ball, which in turn drives the top plate and the sliding column to move and compress the spring; when the external force is released, the spring force pushes the top plate to reset, so that the locking ball returns to the locking position, realizing the switching between locking and releasing.

[0010] Preferably, the protective cover has a multi-section telescopic structure, which allows it to adapt to the large stroke movement of the slider; when the protective cover is fully extended, the limiting plate interlocks with the matching groove on another protective cover, ensuring that the protective cover maintains a flat and stable shielding state when it is in the extended state.

[0011] Preferably, the scraper is fixed to the inner wall of one side of the outer protective cover. The scraper is specifically used to scrape the outer wall of the inner protective cover. This hierarchical design ensures that impurities are effectively scraped off from the inner protective cover during the shrinking process, preventing them from being carried into the folding gap.

[0012] Preferably, in order to achieve synchronous movement, one end of the protective cover is fixedly connected to the slider to ensure that the protective cover can be driven immediately when the slider moves; the other end of the protective cover drives the limit plate to move in order to perform the locking action when extending.

[0013] Preferably, the dust and chip protection structure for the machine tool guide rail also includes a housing, which is located outside the worktable and serves to provide overall protection for the equipment; the worktable is fixedly connected to the top of the housing to form a stable working platform.

[0014] Preferably, to further clarify the structure of the guide rail mechanism, the slider is slidably mounted on the slide rail, and a base plate is fixedly connected to the bottom of the slide rail. This connection method provides a stable and precise guiding foundation for the reciprocating motion of the slider.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model solves the problem of dust accumulation and dirt on machine tool guideways in the prior art by fixing the protective cover to the slider and setting a connecting component of a limiting plate and a scraping plate on the protective cover. It achieves the technical effect of effectively preventing dust and chips from the guideway mechanism and automatically cleaning the surface of the protective cover during the extension and retraction process.

[0017] 2. This utility model solves the problems of inconvenient disassembly and assembly and low maintenance efficiency of key structural components of machine tools in the prior art by setting a locking mechanism between the mounting block and the worktable surface. The locking mechanism uses the cooperation of locking ball, top plate and spring to achieve the technical effect of quick fixing and disassembly of the mounting block.

[0018] 3. This utility model solves the problem of unstable connection when the telescopic protective cover is fully extended in the prior art by using the limiting plate and the groove of the adjacent protective cover to lock each other when the protective cover is extended, thus achieving the technical effect of ensuring the stability and continuous shielding of the protective cover in the extended state.

[0019] 4. This utility model solves the problem of difficult maintenance and replacement of guide rail mechanisms in the prior art by setting a guide rail mechanism consisting of a slide rail, a slider, a base plate, and a mounting platform, and installing it on a detachable mounting block. This achieves the technical effect of facilitating the maintenance and replacement of guide rails and improving the efficiency of machine tool use.

[0020] 5. This utility model, by setting a scraper plate in cooperation with the inside of the protective cover, solves the problem in the prior art that residual impurities cannot be removed when the protective cover shrinks. It achieves the technical effect of simultaneously scraping surface impurities when the protective cover shrinks, ensuring the cleanliness and smooth expansion and contraction of the protective cover.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0031] Example:

[0032] Reference Figures 1 to 4 This utility model provides a dust and chip protection structure for machine tool guideways, which aims to solve the problems of the lack of effective dust and chip protection for machine tool guideways in the prior art, and the difficulty in quickly disassembling and maintaining the overall structure.

[0033] like Figure 1 and Figure 2 As shown, the device includes a housing 1 and a worktable 2 fixedly connected to the top of the housing 1. The housing 1 constitutes the outer cover of the overall equipment. A mounting block 3 is provided on the worktable 2, and a guide rail mechanism 4 is mounted on the mounting block 3. The mounting block 3 and the worktable 2 are detachably connected by a locking mechanism 5. The guide rail mechanism 4 includes a base plate 41 fixedly connected to the mounting block 3, and a slide rail 42 fixedly connected to the base plate 41.

[0034] A slider 43 is slidably connected to the slide rail 42. The slider 43 is slidably set on the slide rail 42, and a mounting platform 44 is fixedly connected to the top of the slider 43.

[0035] The dust and chip protection structure of the machine tool guideway also includes a protective cover 45 and a connecting component 46. Furthermore, the protective cover 45 and the connecting component 46 form a specific structural fit and connection relationship with the aforementioned slider 43.

[0036] Reference Figure 1 , Figure 3 and Figure 4 The protective cover 45 is a multi-section telescopic structure, located on both sides of the slider 43, and moves synchronously with the slider 43. One end of the protective cover 45 is fixedly connected to the slider 43. The connecting component 46 includes a scraper plate 461 and a limiting plate 462. The limiting plate 462 is located at the other end of the protective cover 45 and moves with the protective cover 45. The limiting plate 462 is used to lock with the adjacent protective cover 45 when the protective cover 45 is extended. Specifically, when the protective cover 45 is fully extended, the limiting plate 462 locks with the matching groove on the other protective cover 45 to limit the expansion of the protective cover 45. The scraper plate 461 is fixed to the other end of the protective cover 45. Specifically, the scraper plate 461 is fixed on the inner wall of one side of the outer protective cover 45. In the assembled state, when the protective cover 45 is retracted, the scraper plate 461 is used to scrape the outer wall of the inner protective cover 45.

[0037] Reference Figure 1 The mounting block 3 and the worktable 2 are detachably connected by a locking mechanism 5. The locking mechanism 5 includes a limiting ring 54 set on the inner wall of the worktable 2. A spring 55 is sleeved on the outer wall of the limiting ring 54. The spring 55 abuts against the top plate 52. The top plate 52 is fixedly connected to a sliding column 53. The other side of the top plate 52 abuts against a locking ball 51. The outer wall of the mounting block 3 is used to squeeze the locking ball 51. The locking ball 51 then drives the top plate 52 and the sliding column 53 to move and compress the spring 55. After the external force is released, the spring 55 pushes the top plate 52 to reset.

[0038] Reference Figure 3 and Figure 4 The protective cover 45 is a multi-section telescopic structure. When the protective cover 45 is fully extended, the limiting plate 462 is locked with the matching groove on the other protective cover 45. The scraping plate 461 is fixed on the inner wall of one side of the outer protective cover 45. The scraping plate 461 is used to scrape the outer wall of the inner protective cover 45. One end of the protective cover 45 is fixedly connected to the slider 43. The other end of the protective cover 45 drives the limiting plate 462 to move. The dustproof and chipproof protection structure of the machine tool guide rail also includes a device housing 1. The device housing 1 is set outside the worktable 2. The worktable 2 is fixedly connected to the top of the device housing 1.

[0039] Reference Figure 2 The slider 43 is slidably mounted on the slide rail 42, and the bottom of the slide rail 42 is fixedly connected to the base plate 41.

[0040] The implementation principle of this application embodiment is as follows: When the mounting platform 44 needs to be moved, the mounting platform 44 drives the slider 43 fixedly connected to its bottom to move. The slider 43 slides on the slide rail 42. Since one end of the protective cover 45 is fixedly connected to the slider 43, the slider 43 drives the protective cover 45 to move and unfold synchronously. During the extension of the protective cover 45, the limiting plate 462 set at the other end of the protective cover 45 moves accordingly. When the protective cover 45 is fully extended, the limiting plate 462 and the matching grooves on the adjacent protective cover 45 lock each other, so that the multiple protective covers 45 are connected into a continuous shielding structure, thereby achieving effective dust and chip prevention for the guide rail mechanism 4.

[0041] When the mounting platform 44 moves in the opposite direction and causes the protective cover 45 to retract, the inner protective cover 45 folds inward toward the outer protective cover 45. At this time, the scraper 461 fixed on the inner wall of one side of the outer protective cover 45 will scrape the outer wall of the inner protective cover 45, thereby removing impurities attached to the surface of the protective cover 45 and keeping the structure clean.

[0042] When it is necessary to disassemble the mounting block 3, the outer wall of the mounting block 3 presses against the locking ball 51 of the locking mechanism 5. The locking ball 51 moves inward and abuts against the top plate 52. The top plate 52 drives the sliding column 53 fixedly connected to it to move together. At the same time, the top plate 52 presses against the spring 55 sleeved on the outer wall of the limiting ring 54 to compress it. The locking ball 51 retracts due to compression, releasing the locking of the mounting block 3. The mounting block 3 can then be separated from the worktable 2. When the external force is released, the spring 55 resets and pushes the top plate 52 to reset the locking ball 51, realizing the quick disassembly and maintenance of the structure.
