Description

Technical Field

[0001] This utility model relates to the field of grinding device technology, and in particular to a grinding device for machining the surface of a CNC lathe housing. Background Technology

[0002] During the production and processing of CNC lathes, it is necessary to treat the surface of the outer shell to improve its smoothness. Among them, the grinding process is a key step to improve the smoothness and aesthetics of the outer shell surface.

[0003] Currently, existing grinding machines on the market have certain limitations when grinding CNC lathe shells. Some grinding machines have a small grinding area, and when dealing with large shell surfaces, multiple operations and repeated movements are required, making it difficult to effectively improve grinding efficiency and increasing processing time and labor costs.

[0004] Meanwhile, some handheld grinders lack ease of operation, and prolonged use can easily lead to fatigue for workers, resulting in high labor intensity. Furthermore, existing grinders struggle to achieve precise chamfering on the edges of CNC lathe housings, often resulting in uneven grinding due to edge protrusions and other factors, thus affecting the overall processing quality of the housing. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a grinding device for machining the surface of a CNC lathe housing, which solves some of the problems mentioned in the background art.

[0006] This utility model provides the following technical solution: a grinding device for machining the surface of a CNC lathe shell, comprising a table plate one and a table plate two, a rotating rod provided between the table plate one and the table plate two, the table plate two being rotatably connected to the table plate one via the rotating rod, U-shaped frames symmetrically installed between the lower ends of the table plate one and the table plate two, square bearings slidably installed inside the front and rear ends of the U-shaped frames, drive wheels fixedly installed between the inside of the square bearings, and a sanding belt installed between the drive wheels, partitions provided on the upper side of the square bearings on the U-shaped frames, adjusting screws threaded through and connected to the middle of the partitions, the lower end of the adjusting screws being rotatably connected to the square bearings, and fixing plates fixedly installed near the corners at the front and rear ends of the table plate one and the table plate two, with rollers rotatably installed near the lower side on the fixing plates.

[0007] Furthermore, both the first and second platform plates are provided with a sliding groove in the middle, and a slider is slidably installed inside the sliding groove. The lower ends of the two sets of sliders are fixedly connected to the U-shaped frame, and the sliders provide positioning support for the U-shaped frame, allowing the U-shaped frame to slide.

[0008] Furthermore, a sleeve is fixedly installed at the middle of the upper end of both the first and second platform plates. A sliding rod is slidably connected inside the sleeve. The other end of the sliding rod is fixedly connected to the slider. A return spring is installed inside the sleeve and between the sliding rod for adaptive adjustment between the drive wheels.

[0009] Furthermore, a gantry frame is fixedly installed between the front and rear ends of the rotating rod, and a handle is fixedly installed at the upper end of the gantry frame. Two sets of electric push rods are rotatably installed between the inner top wall of the gantry frame and the platform. The electric push rods can fix the rotation angle of the platform.

[0010] Furthermore, a tensioning wheel is provided in the middle of the sanding belt. The tensioning wheel and the front and rear ends of the rotating rod are rotatably connected to connecting seats. Tensioning springs are fixedly installed between the connecting seats to prevent the sanding belt from loosening and collapsing.

[0011] Furthermore, a driven pulley is fixedly sleeved on the drive wheel located at the second platform near the front side of the shaft core. A main pulley is rotatably mounted on the upper end of the second platform. A transmission belt is provided between the main pulley and the driven pulley. A drive motor is also fixedly mounted on the upper end of the second platform. A transmission assembly is provided between the output end of the drive motor and the main pulley. The drive motor is connected to the main pulley through the transmission assembly to drive the corresponding drive wheel to rotate, thereby driving the sanding belt and another set of drive wheels to rotate.

[0012] The advantages of this utility model are as follows:

[0013] 1. This grinding device, through its rationally designed transmission structure, allows the sanding belt to operate over a wider range. Compared to traditional grinding equipment, this increases the grinding area per operation. In actual operation, workers do not need to frequently move the device or adjust the grinding position to complete the grinding of a larger area of ​​the outer shell surface, effectively improving grinding efficiency. At the same time, the roller design of the device makes it easier and smoother for workers to push or move the device, reducing the labor intensity during operation, improving the overall user experience, and making grinding operations easier and more convenient.

[0014] 2. The electric push rod in this device can drive the table to rotate and bend, allowing the sanding belt to flexibly adjust its angle. When grinding the chamfered edges of the CNC lathe housing, the position of the sanding belt can be precisely adjusted according to the actual angle of the chamfer, ensuring that it fits tightly against the chamfered surface. Combined with the tension spring for stable adjustment of the sanding belt tension, this ensures that the sanding belt maintains a suitable tension during operation, thereby achieving more uniform and effective grinding of the chamfered edges and helping to improve the processing quality of the chamfered edges of the housing.

[0020] 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.

[0021] Please see Figures 1-4A grinding device for machining the surface of a CNC lathe shell includes a first table 1 and a second table 2. A rotating rod 3 is provided between the first table 1 and the second table 2. The second table 2 is rotatably connected to the first table 1 via the rotating rod 3. U-shaped frames 4 are symmetrically installed between the lower ends of the first table 1 and the second table 2. Square bearings 5 ​​are slidably installed inside the front and rear ends of the U-shaped frames 4. Drive wheels 6 are fixedly installed inside the square bearings 5. A sanding belt 7 is installed between the drive wheels 6. A partition plate 8 is provided on the upper side of the square bearings 5 ​​on the U-shaped frames 4. Each partition 8 has an adjusting screw 9 threaded through and connected to the middle of it. The lower end of the adjusting screw 9 is rotatably connected to the square bearing 5. Fixing plates 10 are fixedly installed at the front and rear ends of both platform 1 and platform 2 near the corners. Rollers 11 are rotatably installed on the fixing plates 10 near their lower sides. Both platform 1 and platform 2 have a sliding groove 13 in the middle. Sliding sliders 12 are slidably installed inside the sliding groove 13. The lower ends of the two sets of sliding sliders 12 are fixedly connected to the U-shaped frame 4. At the upper end of the second part, a sleeve 14 is fixedly installed in the middle. A slide rod 15 is slidably connected inside the sleeve 14. The other end of the slide rod 15 is fixedly connected to the slider 12. A return spring 16 is installed between the sleeve 14 and the slide rod 15. The return spring 16 can make the slide rod 15 drive the slider 12 to slide, thereby driving the U-shaped frame 4 to slide and move the two sets of drive wheels 6 away from each other. This allows the sanding belt 7 to have sufficient tension and be driven to rotate by the drive wheels 6 under friction. The operator can hold the handle 18 and place the device on the housing of the CNC lathe. In addition, by rotating the adjusting screw 9, the square bearing 5 can be raised and lowered, so that the lower end of the sanding belt 7 can fully contact the surface of the housing. The rotating sanding belt 7 can then achieve the grinding treatment of the housing surface. Compared with some current grinding machines, this device has a larger grinding area and improves grinding efficiency. At the same time, the design of the roller 11 makes it easier and more convenient for the operator to operate, reducing labor intensity and making it more user-friendly.

[0022] Please see Figure 2A gantry frame 17 is fixedly installed between the front and rear ends of the rotating rod 3. A handle 18 is fixedly installed at the upper end of the gantry frame 17. Two sets of electric push rods 19 are rotatably installed between the inner top wall of the gantry frame 17 and the first platform 1. A tension wheel 20 is set in the middle of the inside of the sanding belt 7. The tension wheel 20 and the front and rear ends of the rotating rod 3 are rotatably connected to the connecting seats 21. Tension springs 22 are fixedly installed between the connecting seats 21. By opening the electric push rod 19 and outputting its extension end, the first platform 1 can be driven to rotate and bend relative to the second platform 2. By forming a certain angle, when grinding the chamfered edges of the housing, the structure on the second plate 2 can be attached to the upper end of the housing. Then, the electric push rod 19 drives the first plate 1 to rotate, so that the corresponding sanding belt 7 is attached to the side end of the housing. The tension spring 22 can pull the tension wheel 20 to retract, so that the sanding belt 7 can maintain stability and appropriate tension when changing the running state. This allows for better grinding of the chamfered edges of the housing, and the uneven grinding caused by edge protrusions will not affect the effect, thus improving the grinding quality.

[0023] Please see Figure 4 A driven pulley 23 is fixedly sleeved on the drive wheel 6 located on the second platform 2 near the front side of the shaft core. A main pulley 24 is rotatably mounted on the upper end of the second platform 2. A transmission belt 25 is provided between the main pulley 24 and the driven pulley 23. A drive motor 26 is also fixedly mounted on the upper end of the second platform 2. A transmission assembly 27 is provided between the output end of the drive motor 26 and the main pulley 24. The drive motor 26 is connected to the main pulley 24 through the transmission assembly 27. By turning on the drive motor 26, the transmission assembly 27 is driven to rotate the main pulley 24. The rotation of the main pulley 24 can drive the driven pulley 23 to rotate through the transmission belt 25. The rotation of the driven pulley 23 can drive the corresponding drive wheel 6 to rotate.

[0024] Working Principle: When in use, this grinding device activates the drive motor 26, which drives the transmission assembly 27 to rotate the main pulley 24. The rotation of the main pulley 24 causes the transmission belt 25 to drive the driven pulley 23, which in turn drives the corresponding drive wheel 6. Simultaneously, the return spring 16 causes the slide bar 15 to slide, which in turn causes the slider 12 to slide, causing the U-shaped frame 4 to move further apart. This allows the sanding belt 7 to have sufficient tension, which, under friction, drives the drive wheel 6 to rotate. The operator can hold the handle 18 and place the device on the CNC lathe housing. Furthermore, rotating the adjusting screw 9 raises and lowers the square bearing 5, ensuring full contact between the lower end of the sanding belt 7 and the housing surface. The rotating sanding belt 7 then grinds the housing surface. Compared to current methods... This device has a larger grinding area than other grinding machines, improving grinding efficiency. The design of the rollers 11 allows for easier and more comfortable operation, reducing labor intensity and making it more user-friendly. Furthermore, by opening the electric push rod 19, its extension end can rotate and bend the table 1 relative to the table 2 at a certain angle. This allows the structure on the table 2 to adhere to the upper part of the housing when grinding the chamfered edges. Then, the electric push rod 19 rotates the table 1, causing the corresponding sanding belt 7 to adhere to the side of the housing. The tension spring 22 pulls the tension wheel 20 to retract, ensuring the sanding belt 7 maintains stability and appropriate tension when changing its operating state. This allows for better grinding of the chamfered edges of the housing, preventing uneven grinding due to edge protrusions and improving grinding quality.
