Description

Technical Field

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

[0002] In the machining of tubular shafts, such as metal tubular shafts, grinding is usually required to ensure the smoothness and precision of the shaft surface. Currently, many grinding devices for tubular shafts use grinding wheels with fixed structures, and the grinding operation is achieved by rotating the shaft or moving the grinding wheel.

[0003] However, existing grinding devices have some shortcomings in practical applications: their adaptability to grinding straight and tapered tube shafts is relatively limited; the adjustment of the height and tilt angle of the grinding wheel is often not convenient enough; and there are certain limitations in flexibly adjusting the contact state between the grinding wheel and the tube shaft according to the shape of the tube shaft, especially the taper of the tapered tube shaft. This may affect grinding efficiency and accuracy, and it is difficult to fully meet the processing needs of diverse tube shafts. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a grinding device for tube and shaft machining.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A grinding device for tube shaft processing includes a base plate, a screw rotatably connected to the base plate, a threaded cylinder threadedly connected to the screw, a frame fixedly connected to the threaded cylinder, a plate rotatably connected to the frame, a plurality of first bolts threaded through the frame, one end of each of the plurality of first bolts contacting the plate, and a grinding plate provided on the plate.

[0006] Preferably, the base plate is fixedly connected to a seat and a rod, the seat is fixedly connected to a motor, the output end of the motor rotates through the rod, and the output end of the motor is fixedly connected to a chuck.

[0007] Preferably, the grinding plate is fixedly connected to the plate body by a second bolt.

[0008] Preferably, a plurality of telescopic rods are fixedly connected between the base plate and the frame, and the plurality of telescopic rods are located at the four corners of the frame.

[0009] Preferably, the contact ends of the plurality of first bolts with the plate are all hemispherical.

[0010] Preferably, the screw is fixedly connected to a handle.

[0011] Preferably, the threaded cylinder is located at the center of the frame.

[0012] The beneficial effects of this utility model are as follows: 1. By using the cooperation between the base plate, screw, threaded cylinder, frame, plate, and first bolt, the screw drives the threaded cylinder to achieve lifting and moving, thereby adjusting the height of the plate and grinding plate. This makes the height adjustment of the grinding plate more convenient and the accuracy easier to control. With the rotational connection between the frame and the plate, and the up and down movement of multiple first bolts at the frame, the plate and grinding plate can be tilted at different angles. This allows for more flexible adaptation to tapered tubes and shafts with different tapers or to maintaining a horizontal state to adapt to straight tubes and shafts. This enhances the adaptability to grinding tubes and shafts of different shapes, and facilitates precise adjustment of the contact state between the grinding plate and the tube and shaft according to the shape of the tube and shaft. This helps to improve grinding efficiency and accuracy and better meet the processing needs of diverse tubes and shafts. 2. Through the coordinated operation of the motor and chuck, the motor provides stable power to the chuck, driving the clamped tube shaft to rotate at a uniform speed. This ensures more even contact and grinding between all parts of the tube shaft's outer surface and the grinding plate, reducing local grinding deviations. At the same time, the chuck can firmly clamp tube shafts of different specifications, preventing them from loosening or shifting during grinding and improving operational stability. Furthermore, the motor speed is easily adjustable, adapting to different materials and grinding precision requirements for tube shaft processing. The overall coordination simplifies the operation process and helps improve grinding efficiency and finished product precision. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Example 1, referring to Figures 1 to 5 A grinding device for tube shaft processing includes a base plate 1, a screw 2 rotatably connected to the base plate 1, and a threaded cylinder 3 threadedly connected to the screw 2. The rotation of the screw 2 can drive the threaded cylinder 3 to move along the axis of the screw 2. The threaded cylinder 3 is fixedly connected to a frame 4, which can synchronously drive the frame 4 to move with the threaded cylinder 3. The frame 4 is rotatably connected to a plate 5, which can adjust the angle of the plate 5 relative to the frame 4. Multiple first bolts 6 are threaded through the frame 4, and one end of each of the multiple first bolts 6 is in contact with the plate 5. By adjusting the screw depth of the first bolts 6, the plate 5 can be supported and its tilt state can be adjusted. The plate 5 is provided with a grinding plate 13, which provides a grinding working surface for grinding the surface of the tube shaft.

[0017] In this embodiment, a base plate 1 is fixedly connected to a seat 7 and a rod 10. A motor 8 is fixedly connected to the base 7. The model of the motor 8 is selected according to actual working requirements. The output end of the motor 8 rotates through the rod 10. The rod 10 can provide stable support for the output end of the motor 8, preventing the output end of the motor 8 from shaking during operation. A chuck 9 is fixedly connected to the output end of the motor 8. The chuck 9 is used to clamp the tube shaft to be processed and can transmit the rotational power of the motor 8 to the tube shaft, driving the tube shaft to rotate synchronously. The grinding plate 13 is fixedly connected to the plate 5 by the second bolt 14. When the grinding plate 13 is worn, aged, or needs to be replaced with a different type of grinding plate 13 according to grinding requirements, the grinding plate 13 can be quickly replaced by removing the second bolt 14, improving the maintenance convenience of the device. Multiple telescopic rods 11 are fixedly connected between the base plate 1 and the frame 4. The telescopic rods 11 are located at the four corners of the frame 4. The telescopic rods 11 can extend and retract synchronously with the lifting and lowering of the frame 4, playing an auxiliary guiding role and preventing the frame 4 from deviating or tilting during the lifting and lowering of the threaded cylinder 3. This ensures that the frame 4 always moves stably in the vertical direction. The contact ends of the multiple first bolts 6 with the plate 5 are all hemispherical. When adjusting the angle of the plate 5, this can prevent the bolt contact ends from getting stuck with the surface of the plate 5, making the angle adjustment of the plate 5 smoother. At the same time, it can also reduce the wear on the surface of the plate 5. The screw 2 is fixedly connected to the handle 12. The handle 12 drives the screw 2 to rotate. The threaded cylinder 3 is located in the center of the frame 4, which can make the supporting force of the threaded cylinder 3 on the frame 4 more balanced. This ensures that the frame 4 is subjected to stable force during the lifting and lowering process and avoids the tilting of the frame 4 due to uneven force. This ensures the positional stability of the grinding plate 13 and improves the grinding accuracy.

[0018] The working principle of this embodiment is as follows: In use, the chuck 9 first firmly clamps the tube shaft to be processed, ensuring its stable fixation. Then, the handle 12 drives the screw 2 to drive the threaded cylinder 3, which in turn drives the plate 5 and grinding plate 13 to adjust their height, allowing for convenient and precise control of the vertical distance between the grinding plate 13 and the tube shaft. Then, through the rotational connection between the frame 4 and the plate 5, the grinding plate 13 is adjusted to an angle that matches the shape of the tube shaft by moving the multiple first bolts 6 at the frame 4 up and down. For straight tube shafts, it remains horizontal, while for tapered tube shafts, it matches their taper. Subsequently, the motor 8 is connected to an external power supply and control device for operation. The motor 8 provides stable power to the chuck 9, driving the chuck 9 to rotate the tube shaft at a uniform speed. At the same time, the speed of the motor 8 can be adjusted according to the tube shaft material and grinding precision requirements, so that all parts of the outer surface of the tube shaft are evenly contacted and ground with the grinding plate 13, reducing deviation. The entire process, through the cooperation of various components, ensures both ease of operation and improves grinding efficiency and finished product precision, meeting diverse tube shaft processing needs.

[0019] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
