Abstract
Description
Technical Field
[0001] This invention relates to the field of sink cutting machine technology, and in particular to a sink cutting machine with stable cutting capabilities. Background Technology
[0002] Existing sink cutting machines mostly use traditional slide rails or simple guide structures to achieve linear motion of the cutting parts. However, these structures usually have the following problems: Insufficient guiding accuracy: Traditional sliding guides are mostly surface contact or clearance fit structures, which are prone to wear during long-term use, resulting in a decrease in guiding accuracy, thereby affecting the straightness of the cutting trajectory and the machining accuracy.
[0003] High frictional resistance: Conventional sliding pairs rely on sliding friction, which has a high coefficient of friction. In high-speed or frequent reciprocating motion, they are prone to jamming and crawling, which not only reduces motion stability but also increases drive energy consumption. Summary of the Invention
[0004] This invention proposes a water tank cutting machine with stable cutting capabilities to solve the problems mentioned in the background art, such as insufficient guiding accuracy and high frictional resistance when existing water tank cutting machines use traditional slide rails or single guide structures to achieve linear motion of the cutting components.
[0005] The technical solution of this invention is implemented as follows: A water tank cutting machine with stable cutting capability includes a water tank, with brackets fixedly connected to both ends of the water tank. The same linear motor is fixedly installed at the top of the two brackets, and the same guide rail is fixedly installed between the two brackets. A sliding frame is slidably installed on the guide rail, and a cutting component is installed at the bottom of the sliding frame. A guide component is installed between the sliding frame and the guide rail.
[0006] Preferably, a groove is formed in the middle of the lower surface of the guide rail, and the guide assembly includes a central guide mechanism disposed in the groove and inside the sliding frame. The central guide mechanism includes an annular frame fixedly installed on the bottom wall of the sliding frame, a central slide rod slidably installed inside the annular frame, a central guide bearing fixedly installed outside the top end of the central slide rod, a central guide rod fixedly installed inside the central slide rod, and a first spring sleeved on the outer surface of the central guide rod.
[0007] Preferably, the end of the central guide rod away from the central slide rod is fixedly installed on the inner wall of the sliding frame, one end of the first spring is fixedly installed on one side of the central slide rod, and the other end of the first spring is fixedly installed on the protrusion of the central guide rod.
[0008] Preferably, the guide assembly further includes an upper guide mechanism, and four upper guide mechanisms are provided, which are respectively located at the four corners of the top wall inside the sliding frame.
[0009] Preferably, the upper guide mechanism includes a telescopic rod fixedly installed on the inner top wall of the sliding frame, an installation rod fixedly installed at the telescopic end of the telescopic rod, a guide bearing fixedly installed at the end of the installation rod, and a second spring sleeved on the outside of the telescopic rod. One end of the second spring is fixedly installed on the inner top wall of the sliding frame, and the other end of the second spring is fixedly installed on the installation rod.
[0010] Preferably, the guide assembly further includes a lower guide mechanism, the structure of which is the same as that of the upper guide mechanism.
[0011] Preferably, the guide bearing of the upper guide mechanism and the guide bearing of the lower guide mechanism are in contact with the upper surface and lower surface of the guide rail, respectively.
[0012] Preferably, the guide assembly further includes a lower guide mechanism, and two lower guide mechanisms are provided, and the two lower guide mechanisms are arranged symmetrically.
[0013] Preferably, the lower guide mechanism includes a fixed rod fixedly installed inside the sliding frame, and both ends of the fixed rod are fixedly installed with lower guide bearings, and the lower guide bearings are in contact with the lower surface of the guide rail.
[0014] Preferably, the cutting assembly includes a motor mounting bracket fixedly installed at the bottom of the sliding frame, a drive motor fixedly installed on the motor mounting bracket, a cutting blade fixedly installed on the drive motor, and a blade cover covering the cutting blade.
[0015] By adopting the above technical solution, the beneficial effects of the present invention are as follows: In this invention, the guide bearings of the upper guide mechanism and the lower guide mechanism are always in contact with the upper and lower surfaces of the guide rail, respectively, and the middle guide bearing is always in contact with the inner wall of the groove. By setting the guide assembly, the sliding frame is ensured to perform high-precision linear motion on the guide rail, thus having the advantage of high guiding accuracy.
[0016] This application adopts a rolling guide bearing method to transform traditional sliding friction into rolling friction, significantly reducing motion resistance and minimizing jamming and crawling during operation. This makes the cutting mechanism run more smoothly and improves processing consistency. Due to the reduced frictional resistance, the output power required by the drive mechanism is reduced, which can reduce energy consumption under the same working conditions and improve the overall operating efficiency of the equipment. The low-friction guide structure reduces the wear between parts, extends the service life of the guide rail, sliding frame and related moving parts, and reduces the dependence on lubrication, thus reducing maintenance frequency and maintenance costs.

[0020] To address the shortcomings of existing sink cutting machines that use traditional slide rails or single guide structures to achieve linear motion of the cutting components, resulting in insufficient guiding accuracy and high frictional resistance, the sink cutting machine with stable cutting provided by this invention, through the setting of guide component 7, has the advantages of precise guiding accuracy and low frictional resistance.
[0021] like Figure 1 and 8 As shown, the present invention provides a water tank cutting machine with stable cutting, including a water tank 1, with brackets 2 fixedly connected to both ends of the water tank 1, the same linear motor 3 fixedly installed at the top of the two brackets 2, the same guide rail 4 fixedly installed between the two brackets 2, a sliding frame 5 slidably installed on the guide rail 4, a cutting component 6 installed at the bottom of the sliding frame 5, and a guide component 7 installed between the sliding frame 5 and the guide rail 4. The linear motor 3 is used to drive the sliding frame 5 to slide on the guide rail 4. The sliding frame 5 drives the cutting component 6 to reciprocate to achieve cutting. Under the guidance of the guide component 7, this application has the advantages of accurate guidance and low frictional resistance.
[0022] In some embodiments, a groove 401 is provided in the middle of the lower surface of the guide rail 4, and the guide assembly 7 includes a central guide mechanism 701 disposed in the groove 401 and inside the sliding frame 5. The central guide mechanism 701 includes an annular frame 7011 fixedly installed on the inner bottom wall of the sliding frame 5, a central slide rod 7012 slidably installed inside the annular frame 7011, a central guide bearing 7013 fixedly installed outside the top end of the central slide rod 7012, a central guide rod 7014 fixedly installed inside the central slide rod 7012, and a first spring 7015 sleeved on the outer surface of the central guide rod 7014. One end of the central guide rod 7014 away from the central slide rod 7012 is fixedly installed on the inner wall of the sliding frame 5. The other end of the central guide rod 7014 passes through the central slide rod 7012 and extends to the outside of the central slide rod 7012. The length of the central guide rod 7014 extending to the outside of the central slide rod 7012 is greater than the maximum displacement of the central slide rod 7012 in the direction away from the inner wall of the groove 401. This ensures that the central slide rod 7012 is always slidably installed on the central guide rod 7014.
[0023] One end of the first spring 7015 is fixedly installed on one side of the middle slide rod 7012, and the other end of the first spring 7015 is fixedly installed on the protrusion of the middle guide rod 7014.
[0024] At least two central guide mechanisms 701 are provided. The two central guide bearings 7013 of the two central guide mechanisms 701 respectively contact the inner walls of the two sides of the groove 401. In this embodiment, three central guide mechanisms 701 are selected. The central guide bearing 7013 of one central guide mechanism 701 contacts the inner wall of one side of the groove 401, and the central guide bearings 7013 of the other two central guide mechanisms 701 contact the inner wall of the other side of the groove 401. The other two central guide bearings 7013 are symmetrically distributed. This arrangement can reduce the friction force when the sliding frame 5 moves on the guide rail 4 under the guidance of the three central guide bearings 7013. It should be noted that the first spring 7015 is initially in a compressed state; When the central guide bearing 7013 moves along the inner wall of the groove 401 with the sliding frame 5, if there is a deformation on the surface of the guide rail 4, the first spring 7015, which is in a compressed state when the deformation is a depression, drives the central slide rod 7012 to slide inside the central guide rod 7014 and the annular frame 7011. During the sliding process, the central slide rod 7012 drives the central guide bearing 7013 to come close to the inner wall of the groove 401. When it moves out of the depression, the central guide bearing 7013 will follow the inner wall of the groove 401 and drive the central slide rod 7012 to move away from the inner wall of the groove 401. At this time, the first spring 7015 returns to its initial compressed state. When the deformation is a bulge, the central guide bearing 7013, following the inner wall of the groove 401, will drive the central slide rod 7012 to move away from the inner wall of the groove 401. At this time, the first spring 7015 is further compressed. When it moves out of the bulge position, the first spring 7015 returns to its initial compressed state. Under the action of the first spring 7015, the central slide rod 7012 can be pulled to move closer to the inner wall of the groove 401, so that the central guide bearing 7013 contacts the inner wall of the groove 401. Under the action of the first spring 7015 and the central slide rod 7012, it can be ensured that the central guide bearing 7013 and the inner wall of the groove 401 remain in constant contact. The central guide bearing 7013 can reduce the friction between the sliding frame 5 and the guide rail 4 when sliding, and can also guide the movement of the sliding frame 5 in the horizontal direction.
[0025] In some embodiments, the guide component 7 further includes an upper guide mechanism 702, and four upper guide mechanisms 702 are provided, with the four upper guide mechanisms 702 respectively located at the four corners of the inner top wall of the sliding frame 5. Each upper guide mechanism 702 includes a telescopic rod 7021 fixedly installed on the inner top wall of the sliding frame 5. A mounting rod 7022 is fixedly installed at the telescopic end of the telescopic rod 7021. A guide bearing 7023 is fixedly installed at the end of the mounting rod 7022. A second spring 7024 is sleeved on the outside of the telescopic rod 7021. One end of the second spring 7024 is fixedly installed on the inner top wall of the sliding frame 5, and the other end of the second spring 7024 is fixedly installed on the mounting rod 7022. It should be noted that the second spring 7024 is initially in a compressed state; When the guide bearing 7023 moves along the upper surface of the guide rail 4 with the sliding frame 5, if there is a deformed position on the surface of the guide rail 4, when the deformation is a depression, the second spring 7024, which is in a compressed state, drives the mounting rod 7022 to move downward, causing the guide bearing 7023 to move downward and contact the surface of the guide rail 4. When it moves out of the depression position, the guide bearing 7023 will follow the surface of the guide rail 4 and drive the mounting rod 7022 to move upward. At this time, the second spring 7024 returns to its initial compressed state. When the deformation is a bulge, the guide bearing 7023 moves with the upper surface of the guide rail 4, which will drive the mounting rod 7022 to move away from the guide rail 4. At this time, the second spring 7024 is further compressed. When it moves out of the bulge position, the second spring 7024 returns to its original compressed state. Under the action of the second spring 7024, the mounting rod 7022 can be pulled to move closer to the surface of the guide rail 4, so that the guide bearing 7023 contacts the surface of the guide rail 4. Under the action of the second spring 7024 and the mounting rod 7022, it can be ensured that the guide bearing 7023 and the upper surface of the guide rail 4 remain in contact. The guide bearing 7023 can reduce the friction between the sliding frame 5 and the guide rail 4 when sliding, and can also guide the movement of the sliding frame 5 in the vertical direction.
[0026] In some embodiments, the guide assembly 7 further includes a lower guide mechanism 703. Two lower guide mechanisms 703 are provided and are arranged symmetrically. The lower guide mechanism 703 includes a fixed rod 7031 fixedly installed inside the sliding frame 5. Both ends of the fixed rod 7031 are fixedly installed with lower guide bearings 7032, and the lower guide bearings 7032 are in contact with the lower surface of the guide rail 4. During the movement of the sliding frame 5, the fixed rod 7031 can be moved. During the movement of the fixed rod 7031, the lower guide bearing 7032 can be moved along the lower surface of the guide rail 4. The lower guide bearing 7032 can reduce the friction between the sliding frame 5 and the guide rail 4 and also guide the movement of the sliding frame 5.
[0027] The combination of the upper guide bearing 7023 and the lower guide bearing 7032 can guide the sliding frame 5 in the vertical direction, so that the frictional resistance is small when the sliding frame 5 slides on the guide rail 4, and at the same time, it can achieve a stable running effect.
[0028] In some other embodiments, the guide assembly 7 further includes a lower guide mechanism 703, the structure of which is the same as that of the upper guide mechanism 702; The guide bearing 7023 of the upper guide mechanism 702 and the guide bearing 7023 of the lower guide mechanism 703 are in contact with the upper and lower surfaces of the guide rail 4, respectively. In this embodiment, the second spring 7024 and the mounting rod 7022 ensure that the middle guide bearing 7023 and the lower surface of the guide rail 4 remain in constant contact. The guide bearing 7023 can reduce the friction between the sliding frame 5 and the guide rail 4 and guide the movement of the sliding frame 5 in the vertical direction. The specific principle is the same as that of the upper guide mechanism 702, and will not be repeated here. This embodiment is preferred in this application to ensure that the guide bearing 7023 remains in contact with the lower surface of the guide rail 4.
[0029] During the movement of the sliding frame 5, the guide bearings 7023 of the upper guide mechanism 702 and the lower guide mechanism 703 remain in contact with the upper and lower surfaces of the guide rail 4, respectively, and the middle guide bearing 7013 remains in contact with the inner wall of the groove 401. Therefore, by setting the guide assembly 7, the friction between the sliding frame 5 and the guide rail 4 can be reduced when the sliding frame 5 moves, and the guiding accuracy can be maintained.
[0030] The cutting assembly 6 includes a motor mounting bracket 8 fixedly installed at the bottom of the sliding frame 5. A drive motor 9 is fixedly installed on the motor mounting bracket 8. A cutting blade 10 is fixedly installed on the drive motor 9. A blade cover 11 is installed on the outside of the cutting blade 10. When the sliding frame 5 slides on the guide rail 4, it can drive the cutting assembly 6 to slide synchronously.
[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
