Description

Technical Field

[0001] This utility model relates to the field of machine tool equipment technology, and more specifically, to a cleaning device and a machine tool. Background Technology

[0002] CNC machine tools continuously generate chips during machining. These chips are usually mixed with coolant and discharged through a chip removal system. However, in actual use, some chips adhere to the surface of the machine tool's internal protective cover or accumulate in hard-to-reach corners. This not only causes wear between the internal protective cover and moving parts, shortening the service life of the internal protective cover, but may also cause component interference due to chip accumulation, affecting the normal operation of the machine tool.

[0003] In the current technology, the cleaning of chips inside machine tools mainly relies on manual entry into the machine tool for processing. However, this method is not only labor-intensive and poses certain safety hazards, but also has limited cleaning effect. Utility Model Content

[0004] This utility model provides a cleaning device and machine tool to solve the problems of high labor intensity, safety hazards and limited cleaning effect of existing cleaning methods.

[0005] To address the aforementioned problems, according to one aspect of this utility model, a cleaning device is provided, disposed on the housing structure of a machine tool, comprising: a cylindrical cleaning structure, rotatably disposed, abutting against the inner protective cover of the machine tool, wherein the cleaning structure cleans chips on the inner protective cover when rotating; a driving structure disposed within the cleaning structure, the driving structure driving the cleaning structure to rotate; and a telescopic structure, telescopically disposed, one end of the telescopic structure being connected to one end of the driving structure, the telescopic structure adjusting the relative position of the cleaning structure and the inner protective cover by telescopic movement.

[0006] Furthermore, the cleaning structure includes an outer roller and a brush. The drive structure drives the outer roller to rotate, and the brush is arranged on the outer surface of the outer roller along the circumference and axial direction. The brush abuts against the inner protective cover.

[0007] Furthermore, the cleaning device also includes an external water tank and a water spray pipe. One end of the water spray pipe is connected to the external water tank, and the other end of the water spray pipe is equipped with a nozzle for spraying water onto the cleaning area of ​​the cleaning structure.

[0008] Furthermore, the cleaning device also includes a drying structure, which is located at one end of the telescopic structure near the cleaning structure, and is used to dry the inner protective cover.

[0009] Furthermore, the cleaning device also includes a rotating structure connected to the end of the telescopic structure away from the cleaning structure, and the rotating structure is used to drive the telescopic structure to swing.

[0010] Furthermore, the cleaning device also includes a base, which is fixedly installed on the housing structure. An arc-shaped limiting groove is provided at one end of the base facing the rotating structure. The rotating structure includes a rotating body and a rotating sleeve. The rotating body is connected to the telescopic structure and drives the telescopic structure to swing. The rotating sleeve is installed inside the rotating body and a limiting block is provided on the rotating sleeve. The limiting block slides in conjunction with the limiting groove.

[0011] Furthermore, the cleaning device also includes a right-angle connector, the two ends of which extend perpendicularly to each other. One end of the right-angle connector is connected to the telescopic structure, and the other end is connected to the drive structure.

[0012] Furthermore, the telescopic structure includes a cylinder, a first telescopic sleeve, and a second telescopic sleeve, which are sleeved together.

[0021] 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. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0022] like Figures 1 to 2 As shown, an embodiment of this utility model provides a cleaning device, which is installed on the housing structure 81 of a machine tool. The device includes: a cylindrical cleaning structure 10, rotatably mounted, abutting against the inner protective cover 82 of the machine tool, and cleaning chips from the inner protective cover 82 when rotating; a driving structure, installed inside the cleaning structure 10, which drives the cleaning structure 10 to rotate; and a telescopic structure 20, telescopically mounted, with one end connected to one end of the driving structure, which adjusts the relative position of the cleaning structure 10 and the inner protective cover 82 by extending and retracting.

[0023] In this embodiment, a cylindrical cleaning structure 10 is provided on the housing structure 81 of the machine tool, and the cleaning structure 10 is rotatably abutted against the inner protective cover 82 of the machine tool. This allows for continuous cleaning of chips attached to the surface of the inner protective cover 82. Compared with existing methods that rely on manual cleaning or fixed air jet / water flushing devices, the cleaning device in this application can achieve automated and continuous cleaning operations. This effectively prevents metal chips such as iron and aluminum chips from adhering to the surface of the inner protective cover 82 for a long time, reduces the risk of wear between the inner protective cover 82 and other moving parts, extends the service life of the inner protective cover 82 and related components, and avoids the need for manual entry into the machine tool for cleaning, thus reducing labor intensity and safety risks. Moreover, the cleaning structure 10 is equipped with a drive structure that can directly drive the cleaning structure 10 to rotate, realizing an integrated design of drive and cleaning, making the overall structure more compact and reducing the installation space requirements of the cleaning device. In addition, the telescopic structure 20 can be extended and retracted according to the machine tool's operating status and the actual position of the inner protective cover 82, so that the cleaning structure 10 and the inner protective cover 82 maintain a reasonable contact state. This not only adapts to the cleaning needs under different working conditions and avoids cleaning blind spots, but also effectively covers dead corners and ensures the comprehensiveness of the cleaning range, thereby achieving a more thorough cleaning of the inner protective cover 82.

[0024] The drive structure includes a stator, a rotor, and a drive shaft. The stator and the outer roller 11 are fitted with a clearance. The rotor is located inside the stator and is connected to one end of the drive shaft. The other end of the drive shaft is connected to the outer roller 11 to drive the outer roller 11 to rotate.

[0025] like Figure 1 and Figure 2 As shown, the cleaning structure 10 includes an outer roller 11 and a brush. The driving structure drives the outer roller 11 to rotate. The brush is arranged on the outer surface of the outer roller 11 along the circumference and axial direction. The brush abuts against the inner protective cover 82.

[0026] In this embodiment, the brush is arranged on the outer surface of the outer roller 11 along the circumference and axial direction, which can achieve all-round cleaning of the inner protective cover 82 during the rotation of the outer roller 11, remove metal chips and residual coolant attached to the inner protective cover 82, avoid cleaning dead corners, reduce the adhesion and wear problems caused by long-term accumulation of chips, and ensure complete cleaning of the surface of the inner protective cover 82.

[0027] Considering that the brushes on the outer periphery of the outer roller 11 are easily worn during use, a barbed structure is adopted in the design of the brushes. This allows the brushes to be pulled out in the direction of the outer roller 11, making them easy to install and replace.

[0028] Alternatively, the brush can be made of a flexible material, allowing for flexible contact between the brush and the inner protective cover 82. This ensures effective cleaning while preventing excessive abrasion or damage to the surface of the inner protective cover 82. Alternatively, the brush material can be selected from wear-resistant and coolant-corrosion-resistant fibers, depending on the operating conditions, thereby further improving the brush's durability and service life.

[0029] Specifically, the cleaning device also includes an external water tank and a water spray pipe. One end of the water spray pipe is connected to the external water tank, and the other end is equipped with a nozzle for spraying water onto the cleaning area of ​​the cleaning structure 10. Water spraying effectively washes away metal particles such as iron filings and aluminum filings, along with coolant residue, adhering to the inner protective cover 82. Furthermore, for chips with strong adhesion after being wetted by coolant, water spraying reduces the stickiness between the chips and the surface of the inner protective cover 82, improving cleaning efficiency. Simultaneously, the external water tank provides a stable water source, ensuring continuous water spraying from the water spray pipe and nozzle. This not only facilitates rapid chip removal but also provides cooling and lubrication to some extent, preventing damage to the brushes or the inner protective cover 82 caused by localized heating due to friction.

[0030] like Figure 1 and Figure 2 As shown, the cleaning device also includes a drying structure 30, which is located at the end of the telescopic structure 20 near the cleaning structure 10. The drying structure 30 dries the inner protective cover 82 immediately after water spraying, rapidly reducing residual moisture on the surface of the inner protective cover 82 and decreasing the adhesion between chips and the surface of the inner protective cover 82. This improves the efficiency of chip removal and discharge, preventing wet chips from re-adhering and causing secondary contamination or accumulation. Furthermore, timely drying of the inner protective cover 82 surface helps reduce the residence time of moisture on the surface, lowering the risk of corrosion, rust, or chemical erosion caused by coolant residue. This reduces damage to the inner protective cover 82 and other components, extending the device's service life and reducing maintenance and replacement frequency and related maintenance costs.

[0031] like Figure 1 and Figure 2 As shown, the cleaning device also includes a rotating structure 40, which is connected to the end of the telescopic structure 20 away from the cleaning structure 10. The rotating structure 40 is used to drive the telescopic structure 20 to swing, thereby enabling the cleaning structure 10 to cover a wider cleaning trajectory, thus ensuring that the surface of the protective cover 82 inside the machine tool and its dead corners are fully cleaned, avoiding blind spots where chips accumulate.

[0032] like Figure 1 and Figure 2As shown, the cleaning device also includes a base 50, which is fixedly installed on the housing structure 81. An arc-shaped limiting groove is provided at one end of the base 50 facing the rotating structure 40. The rotating structure 40 includes a rotating body and a rotating sleeve. The rotating body is connected to the telescopic structure 20. The rotating body drives the telescopic structure 20 to swing. The rotating sleeve is installed inside the rotating body. A limiting block is provided on the rotating sleeve. The limiting block slides in conjunction with the limiting groove.

[0033] In this embodiment, the sliding engagement between the arc-shaped limiting groove and the limiting block limits the swing angle of the rotating structure 40, preventing excessive swinging or deviation of the cleaning structure 10 during operation and ensuring the stability and controllability of the cleaning trajectory. Furthermore, the sliding engagement between the limiting block and the limiting groove provides guidance during swinging, reducing vibration or impact caused by inertia or uneven force on the rotating body, and extending the service life of the rotating structure 40 and the telescopic structure 20. Additionally, the fixing of the base 50 to the housing structure 81 provides reliable installation support for the entire rotating structure 40, making the overall operation of the cleaning device more stable.

[0034] like Figure 1 and Figure 2 As shown, the cleaning device also includes a right-angle connector 60, the two ends of which extend perpendicularly to each other. One end of the right-angle connector 60 is connected to the telescopic structure 20, and the other end of the right-angle connector 60 is connected to the drive structure.

[0035] In this embodiment, the right-angle transition not only facilitates the transmission of power from the drive structure or telescopic structure 20 to the cleaning structure 10, but also optimizes the overall layout of the cleaning device, reduces interference between the drive structure and the telescopic structure 20, and ensures that the cleaning device can be installed reasonably in a limited space.

[0036] like Figure 1 and Figure 2 As shown, the telescopic structure 20 includes a cylinder, a first telescopic sleeve 21 and a second telescopic sleeve 22. The first telescopic sleeve 21 and the second telescopic sleeve 22 are sleeved together, and the end of the second telescopic sleeve 22 is connected to the right-angle connector 60. The cylinder is disposed inside the first telescopic sleeve 21 and the second telescopic sleeve 22. The cylinder adjusts the overlap length of the first telescopic sleeve 21 and the second telescopic sleeve 22 by telescopic extension.

[0037] In this embodiment, by adjusting the overlap length of the first telescopic sleeve 21 and the second telescopic sleeve 22, the cleaning range can be adjusted according to different positions inside the machine tool and the chip accumulation, thereby cleaning the surface of the protective cover 82 inside the machine tool and hard-to-reach dead corners. Furthermore, due to the adjustable nature of the first telescopic sleeve 21 and the second telescopic sleeve 22, the cleaning device can avoid collisions with the machine tool and moving parts during the cleaning process, reducing component wear and interference, and extending the service life of the machine tool protective components. Moreover, the cleaning device in this application does not require manual entry into the machine tool, reducing labor intensity and safety risks.

[0038] like Figure 1 and Figure 2 As shown, the cleaning device also includes a bottom cover plate 70, which is located at the end of the cleaning structure 10 away from the telescopic structure 20. It can prevent chips and coolant from entering the uncleaned area inside the machine tool, avoid chip accumulation again, and maintain a clean environment inside the machine tool.

[0039] An embodiment of this utility model also provides a machine tool including the aforementioned cleaning device, enabling automatic cleaning of chips and coolant during machining without requiring manual entry into the machine tool, thereby reducing labor intensity and improving operational safety. Furthermore, the cleaning device in this application, through the synergistic action of the telescopic structure 20, the bottom cover plate 70, and the cleaning structure 10, can flexibly clean the surface of the internal protective plate of the machine tool and hard-to-reach corners, preventing chip accumulation, reducing interference and wear of internal moving parts, and improving the long-term stability and machining reliability of the machine tool.
