Description

Technical Field

[0001] This application relates to the field of CNC sawing machine cleaning technology, and in particular to a cleaning device for CNC sawing machines. Background Technology

[0002] CNC sawing machines use circular saw blades, saw bands, or saw strips as cutting tools to saw metal round, square, pipe, and profile materials. The machining accuracy of sawing machines is generally not very high, and they are mostly used in material preparation workshops to cut various bars, pipes, and other profile materials. During the processing of profile materials, sawing machines generate a large amount of debris, which needs to be cleaned up in a timely manner.

[0003] A related technology includes a CNC saw cleaning device, which includes a handle with a rotating shaft rotatably mounted on it. A drive component is installed on the handle to drive the rotating shaft to rotate. A brush head is coaxially connected to the rotating shaft. When cleaning the CNC saw, the operator holds the handle and uses the drive component to drive the rotating shaft to rotate. The rotating shaft drives the brush head to rotate, and the rotating brush head contacts the CNC saw to clean it.

[0004] In the process of developing this application, it was found that the technology has at least the following problems: the existing CNC sawing machine has a complex structure, the spacing between some parts on the CNC saw teeth is small, the brush head is difficult to penetrate into the gaps between the parts for cleaning, there are cleaning dead corners, and the cleaning degree needs to be improved. Utility Model Content

[0005] To facilitate cleaning the gaps between small-pitch components and reduce cleaning dead spots, this application provides a cleaning device for CNC sawing machines.

[0006] The cleaning device for a CNC sawing machine provided in this application adopts the following technical solution:

[0007] A cleaning device for a CNC sawing machine includes a handle, a mounting frame fixedly mounted at the end of the handle, a sliding sleeve slidably mounted on the mounting frame, a rotating sleeve rotatably mounted at the end of the sliding sleeve, and a plurality of first shells symmetrically and hingedly mounted on the circumference of the end of the rotating sleeve; a driving component fixedly mounted on the handle, a rotating shaft rotatably mounted inside the mounting frame, one end of the rotating shaft being coaxially fixed to the output end of the driving component, and an end cap coaxially fixed to the other end of the rotating shaft, a plurality of second shells symmetrically and hingedly mounted on the circumference of the end cap, the first shells and the second shells corresponding one-to-one and hinged to each other, bristles being provided on the outer sides of the first shells, second shells, rotating sleeve, and end caps, and a sliding assembly being provided on the mounting frame for driving the sliding sleeve to slide.

[0008] By adopting the above technical solution, under normal conditions, the end cover, all first shells, all second shells, and rotating sleeve form a cylindrical cleaning structure. During normal cleaning of the CNC sawing machine, the operator holds the handle and drives the rotating shaft to rotate through the drive component. The rotating shaft drives the end cover to rotate, and the end cover drives all first shells, all second shells, and rotating sleeve to rotate around the rotating shaft together. At this time, all the bristles also rotate along the rotating shaft, bringing the bristles into contact with the surface of the CNC sawing machine for rapid cleaning. When encountering areas with small spacing between parts on the CNC sawing machine, the sliding component drives the sliding sleeve to slide on the mounting frame. The sliding sleeve drives the rotating sleeve to slide, and the hinge area between the first shell and the second shell bulges away from the rotating shaft until the inner sides of the first shell and the second shell abut against each other. At this time, the first shell and the second shell fold to form a flat cleaning structure. This flat cleaning structure forms a disc-shaped cleaning area when rotating, which is convenient for reaching between small-pitch parts to clean narrow spaces, reducing cleaning dead corners and improving the cleaning degree.

[0009] Preferably, the driving component includes a gear and a rack, the gear being rotatably mounted on the mounting bracket, and the rack being fixedly mounted on the sliding sleeve, with the gear and rack meshing with each other.

[0010] By adopting the above technical solution, when it is necessary to drive the sliding sleeve to slide, the gear is rotated, and the gear and rack mesh with each other, thereby driving the rack to move, thus realizing the stable sliding of the sliding sleeve on the mounting bracket. This gear and rack transmission method has the advantages of high transmission accuracy and compact structure, and can effectively ensure the accuracy and stability of the sliding sleeve.

[0011] Preferably, the mounting bracket has a sliding groove at its bottom, and the rack slides within the sliding groove.

[0012] By adopting the above technical solution, the slide groove provides guidance and limit for the sliding of the rack, enabling the rack to move smoothly along the predetermined path, minimizing circumferential deflection between the sliding sleeve and the mounting bracket, and minimizing rack offset or wobbling during movement, thereby ensuring the stability and reliability of gear and rack transmission.

[0013] Preferably, the driving component further includes a plate buckle, and the gear is a circular arc gear, with the plate buckle fixedly connected to the gear.

[0014] By adopting the above technical solution, when encountering areas with small spacing between parts on a CNC sawing machine, the operator can hold the handle and hook one finger onto the plate buckle. The operator can then drive the arc gear to rotate by hooking the plate buckle, thereby achieving the sliding of the sleeve. This increases the operational flexibility of the device and facilitates one-handed operation.

[0015] Preferably, a return spring is provided between the rotating sleeve and the end cover. One end of the return spring abuts against the rotating sleeve, and the other end of the return spring abuts against the end cover. The return spring drives the rotating sleeve away from the end cover.

[0016] By adopting the above technical solution, after the sliding sleeve slides to form a flat cleaning structure for cleaning of the first and second shells, when it is necessary to restore the normal cylindrical cleaning structure, the return spring can provide the elastic force for restoration, helping the rotating sleeve to automatically move away from the end cover, so that the first and second shells can quickly return to the initial unfolded state when no external force is applied, which facilitates the continuation of the cleaning operation of the regular area and improves the cleaning efficiency.

[0017] Preferably, the driving component is a motor.

[0018] By adopting the above technical solution, the motor drive has the advantages of convenient operation and high degree of automation, and can provide stable and continuous power for the rotation of the rotating shaft.

[0019] Preferably, the inner side of the rotating sleeve is in close contact with the rotating shaft and has a sliding fit.

[0020] By adopting the above technical solution, the inner side of the rotating sleeve is in close contact with the rotating shaft, which increases the stability of the rotating sleeve rotation and reduces the vibration phenomenon of the sliding sleeve during the sliding process. The sliding cooperation between the rotating sleeve and the rotating shaft allows the rotating shaft to directly apply the torsional force to the rotating sleeve during the rotation process, without having to transmit the torsional force through the end cover, the first shell, and the second shell, which further ensures the stability between the rotating sleeve and the rotating shaft.

[0021] Preferably, a meshing block is fixedly provided on the inner side of the rotating sleeve, and a meshing groove is provided on the peripheral wall of the rotating shaft. The meshing block extends into the meshing groove and slides and engages with the meshing groove.

[0022] By adopting the above technical solution, the cooperation between the meshing block and the meshing groove further improves the stability of the rotating sleeve sliding on the rotating shaft, preventing the rotating sleeve from deviating or jamming during the sliding process. At the same time, it also enhances the reliability of the rotating shaft transmitting power to the rotating sleeve, making the cleaning device work more smoothly and efficiently.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By setting up a mounting bracket, sliding sleeve, rotating sleeve, first housing, driving component, rotating shaft, end cover, second housing, and brush bristles, it is convenient to clean the gaps between small-pitch components and reduce cleaning dead angles;

[0025] 2. By setting gears, racks, plate buckles, and return springs, the sliding sleeve can be stably slid on the mounting frame, and the sliding sleeve can also be automatically reset, which facilitates one-handed operation and increases the operational flexibility of the device;

[0026] 3. By setting up meshing blocks and meshing grooves, the rotating shaft can directly transmit the torsional force to the rotating sleeve during rotation, without having to transmit the torsional force through the end cover, the first shell, and the second shell, thus further ensuring the circumferential stability between the rotating sleeve and the rotating shaft.

Detailed Implementation

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0033] This application discloses a cleaning device for a CNC sawing machine. (Refer to...) Figure 1 It includes a handle 1, with a mounting bracket 2 fixed to the top of the handle 1. A sliding sleeve 21 is slidably provided at the end of the mounting bracket 2, and a rotating sleeve 22 is rotatably provided at the end of the sliding sleeve 21. Several first shells 23 are symmetrically and hingedly provided on the circumference of the end of the rotating sleeve 22. The cross-section of the first shells 23 is arc-shaped, and all the first shells 23 can together form a cylindrical structure.

[0034] Reference Figure 1 and Figure 2A drive component 24, which is a motor, is fixedly mounted on the handle 1. A rotating shaft 25 is rotatably mounted inside the mounting frame 2. One end of the rotating shaft 25 is coaxially fixed to the output end of the drive component 24, and the other end of the rotating shaft 25 is coaxially fixed to an end cap 251. Several second shells 26 are symmetrically and hingedly mounted on the circumference of the end cap 251. The cross-section of the second shells 26 is arc-shaped, and all the second shells 26 can also form a cylindrical structure. The first shell 23 corresponds one-to-one with the second shells 26 and is hinged to each other. Brush bristles 27 are provided on the outer sides of the first shell 23, the second shell 26, the rotating sleeve 22, and the end cap 251. A sliding assembly 3 is also provided on the mounting frame 2, which is used to drive the sliding sleeve 21 to slide.

[0035] Reference Figures 1 to 3 This embodiment has two states. State 1 is the normal state, used for normal cleaning of the CNC sawing machine. In the normal state, the sliding component 3 does not drive the sliding sleeve 21 to slide. At this time, the end cover 251, all the first shells 23, all the second shells 26, and the rotating sleeve 22 form a cylindrical cleaning structure. The operator holds the handle 1, and the driving component 24 drives the rotating shaft 25 to rotate, thereby causing the end cover 251, all the first shells 23, all the second shells 26, and the rotating sleeve 22 to rotate together. At this time, the brush bristles 27 also rotate, contacting the surface of the CNC sawing machine for rapid cleaning. State 2 is a special state, used when encountering areas with small spacing between parts on the CNC sawing machine. In the special state, the sliding component 3 drives the sliding sleeve 21 to slide. At this time, the sliding sleeve 21 drives the rotating sleeve 22 to slide, and the rotating sleeve 22 moves closer to the end cover 251. The hinge area between the first shell 23 and the second shell 26 bulges away from the rotation axis 25 until the inner sides of the first shell 23 and the second shell 26 abut against each other. At this time, each first shell 23 and the corresponding second shell 26 fold together to form a flat cleaning structure, and the first shell 23 and the second shell 26 in the cleaning structure are inserted between small-pitch parts, which makes it easier to insert the first shell 23 and the second shell 26 into the small-pitch parts to clean the narrow space, thereby reducing cleaning dead corners and improving the cleaning degree.

[0036] To facilitate the sliding of the sleeve 21, refer to... Figure 2 and Figure 4The driving component 24 includes a gear 31, a rack 32, and a plate buckle 33. The rack 32 is fixedly mounted on the sliding sleeve 21, and a groove is provided at the bottom of the mounting frame 2, within which the rack 32 slides. The gear 31 is rotatably mounted on the mounting frame 2, and the gear 31 meshes with the rack 32 within the groove. The gear 31 is an arc gear, and the plate buckle 33 is fixedly connected to the gear 31. When the sliding sleeve 21 needs to be moved, the operator grips the handle and hooks their fingers onto the plate buckle 33, applying force. The plate buckle 33 drives the gear 31 to rotate, and the gear 31 meshes with the rack 32, thereby causing the rack 32 to slide, thus achieving stable sliding of the sliding sleeve 21 on the mounting frame 2. This increases the operational flexibility of the device and facilitates one-handed operation.

[0037] To facilitate the automatic reset of the sliding sleeve 21, refer to... Figure 2 and Figure 3 A return spring 28 is provided between the rotating sleeve 22 and the end cover 251. One end of the return spring 28 abuts against the rotating sleeve 22, and the other end abuts against the end cover 251. The return spring 28 drives the rotating sleeve 22 away from the end cover 251. When the plate buckle 33 is released, the return spring 28 automatically drives the rotating sleeve 22 away from the end cover 251, so that the first shell 23 and the second shell 26 can quickly return to state one when no external force is applied, which facilitates the continued normal cleaning of the CNC saw.

[0038] In order for the rotating shaft 25 to directly transmit power to the rotating sleeve 22, refer to Figure 2 The inner side of the rotating sleeve 22 is in close contact with and slides against the rotating shaft 25. A meshing block 221 is fixedly installed on the inner side of the rotating sleeve 22. A meshing groove 252 is formed on the peripheral wall of the rotating shaft 25. The meshing block extends into the meshing groove 252 and slides against it. The cooperation between the meshing block 221 and the meshing groove 252 further improves the stability of the rotating sleeve 22 sliding on the rotating shaft 25, allowing the rotating shaft 25 to directly transmit power to the rotating sleeve 22 through the meshing groove 252 and the meshing block 221.

[0039] The implementation principle of a cleaning device for a CNC sawing machine according to an embodiment of this application is as follows: When cleaning the CNC sawing machine, the working state is selected according to the actual situation. When cleaning a regular area, the operator holds the handle 1 and starts the drive component 24, i.e., the motor. The motor drives the rotating shaft 25 to rotate, thereby causing the end cover 251, the first casing 23, the second casing 26, and the rotating sleeve 22 to rotate together, so that the bristles 27 come into contact with the surface of the CNC sawing machine, achieving rapid cleaning.

[0040] When encountering areas with small gaps between parts, the operator holds handle 1, grips the buckle 33 with their fingers, and applies force. The buckle 33 drives the gear 31 to rotate, and the gear 31 meshes with the rack 32, causing the sliding sleeve 21 to slide. The sliding sleeve 21 drives the rotating sleeve 22 closer to the end cover 251, and the first casing 23 and the second casing 26 fold to form a flat cleaning structure. Then, the motor is started, and the first casing 23 and the second casing 26 are inserted between the small-pitched parts to clean the areas with small gaps. After cleaning, the buckle 33 is released, and the return spring 28 returns the rotating sleeve 22 to its normal position, allowing the device to continue cleaning other areas.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
