Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing technology, and specifically relates to a device for grinding the ends of pipes. Background Technology

[0002] The piping systems of aerospace vehicles include fuel lines, hydraulic lines, and fuel lines. These systems are the lifeline of the aircraft, directly affecting its overall performance. The reliability and durability of these piping systems are crucial factors in meeting airworthiness requirements, ensuring flight safety, and reducing maintenance costs.

[0003] Aviation tubing is mostly made of alloy metal. During the initial rolling process, to save steps, the length of a single tube is generally between 3 and 6 meters, thus requiring cutting as needed. The cut tube ends typically have burrs of varying sizes. These burrs not only affect the product's appearance but may also impact its performance and safety.

[0004] In existing technologies, mechanical grinding is generally used to improve grinding efficiency. However, some existing grinding machines have problems such as insufficient grinding precision and high rework rates. Utility Model Content

[0005] The purpose of this utility model is to provide a pipe end grinding device that can improve the grinding precision while completing automatic clamping and grinding, thereby improving grinding efficiency.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A pipe end grinding device includes a base and grinding equipment respectively disposed at both ends of the base; the grinding equipment includes a dust cover, an adjustment mechanism disposed inside the dust cover, a grinding mechanism and a clamping mechanism connected to the adjustment mechanism; the grinding mechanism includes a motor mounting back plate connected to the adjustment mechanism, a drive motor connected to the motor mounting back plate, a grinding wheel connected to the drive motor, and an air blowing mechanism disposed on one side of the grinding wheel.

[0008] Furthermore, the adjustment mechanism includes a lateral translation machine, a longitudinal translation machine, and a lifting machine. The lifting machine is mounted on the longitudinal translation machine, the longitudinal translation machine is mounted on the lateral translation machine, and the lateral translation machine is mounted on the base.

[0009] Furthermore, the lateral translation machine is mounted on the base, and a lateral translation rack is provided on the lateral translation machine.

[0010] Furthermore, the elevator includes a column, a reinforcing support rib connected between the column and the longitudinal translation machine, and a U-shaped lifting bracket connected to the column, and the grinding mechanism is connected to the U-shaped lifting bracket.

[0011] Furthermore, the column is equipped with a lifting rack.

[0012] Furthermore, the motor mounting back plate is slidably connected to the slide rail, and one side of the motor mounting back plate is fixed to the U-shaped lifting bracket.

[0013] Furthermore, the output shaft of the drive motor is vertically downward, and a grinding wheel is connected to the end of the output shaft.

[0014] Furthermore, the clamping mechanism includes a pneumatic gripper and a V-shaped positioning block connected to the pneumatic gripper. The V-shaped positioning block includes at least two blocks, and the two V-shaped positioning blocks are respectively installed at both ends of the pneumatic gripper and are arranged symmetrically.

[0015] Furthermore, a photoelectric emitter is provided on the side of the V-shaped positioning block and positioned opposite to it.

[0016] Furthermore, the base is provided with a grinding mechanism position adjustment rack.

[0017] Compared with the prior art, the advantages of this utility model are as follows: First, this utility model adopts grinding equipment at both ends of the base, which can grind both ends of the tube separately, reducing the number of times to re-clamp and position, and effectively improving processing efficiency.

[0018] Secondly, this invention has a wider range of applications, suitable for pipes of different diameters and lengths, and achieves a high burr removal rate. This is because, on one hand, the invention uses a three-coordinate moving system to adjust the position of the grinding mechanism; on the other hand, the grinding equipment can be positioned on the base.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0026] In the description of this utility model, it should be noted that if terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" appear to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0027] Furthermore, the terms "first," "second," and "third" are used only for distinguishing descriptions and should not be interpreted as indicating or implying relative importance.

[0028] Furthermore, the use of terms such as "horizontal," "vertical," and "suspended" does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0029] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0031] like Figures 1-3 As shown, a pipe end grinding device includes a base 13 and grinding equipment 14 respectively disposed at both ends of the base 13; the grinding equipment 14 includes a dust cover 15, an adjustment mechanism disposed inside the dust cover 15, a grinding mechanism and a clamping mechanism connected to the adjustment mechanism; the grinding mechanism includes a motor mounting back plate connected to the adjustment mechanism, a drive motor connected to the motor mounting back plate, a grinding wheel 16 connected to the drive motor, and an air blowing mechanism 17 disposed on one side of the grinding wheel 16.

[0032] Compared to existing technologies, where significant burrs and flash are present during pipe cutting due to on-site conditions, manual scraping is currently used, resulting in substantial waste of labor costs. This invention, however, employs a PLC and servo system for precise control, achieving a repeatability accuracy of ±0.05mm, high movement speed, short polishing time, and a custom-designed polishing wheel (16) with minimal dust. Furthermore, this invention features symmetrically arranged polishing devices (14) at both ends of the base (13), each including a clamping mechanism and a polishing mechanism. By clamping and polishing at both ends, it is suitable for polishing pipes of various materials (aluminum, copper, titanium, alloy pipes, etc.) with lengths ranging from 150 to 2000mm (inclusive), broadening its applicability. Additionally, this invention incorporates a three-coordinate adjustment system, allowing adjustment of the height and position of the polishing mechanism according to the pipe diameter, making it suitable for polishing pipes from φ6 to φ85mm. Furthermore, the entire polishing process can be automated, improving processing efficiency.

[0033] The adjustment mechanism includes a horizontal translation machine 21, a vertical translation machine 24, and a lifting machine. The lifting machine is mounted on the vertical translation machine 24, and the vertical translation machine 24 is mounted on the horizontal translation machine 21. The horizontal translation machine 21 is mounted on the base 13. The horizontal translation machine 21 is mounted on the base 13 and has a horizontal translation rack. The lifting machine includes a column 22, a reinforcing support rib 23 connecting the column 22 and the vertical translation machine 24, and a U-shaped lifting bracket 25 connected to the column 22. A grinding mechanism is connected to the U-shaped lifting bracket 25. This utility model uses the horizontal translation machine 21, the vertical translation machine 24, and the lifting machine as a three-axis adjustment mechanism, i.e., the XYZ three-axis direction. The horizontal translation machine 21, the vertical translation machine 24, and the lifting machine are all mainly driven by servo motors, achieving movement on the rack.

[0034] The column 22 is provided with a lifting rack 26.

[0035] The motor mounting backplate is slidably connected to the slide rail, and one side of the motor mounting backplate is fixed to the U-shaped lifting bracket 25. The output shaft of the drive motor is vertically downward, and a grinding wheel 16 is connected to the end of the output shaft.

[0036] The clamping mechanism includes pneumatic grippers and V-shaped positioning blocks 18 connected to the pneumatic grippers. At least two V-shaped positioning blocks 18 are provided, each mounted symmetrically at one end of the pneumatic gripper. Optical photoelectric emitters 20 are positioned on the sides of each V-shaped positioning block 18. This invention utilizes adjustable pneumatic grippers for clamping pipes of different diameters. A telescopic cylinder controls the pneumatic grippers to move to both sides, separating the two V-shaped positioning blocks. The pipe to be polished is then placed between the V-shaped positioning blocks 18, and the alignment of the pipe with the corresponding photoelectric signal emitted by the photoelectric emitters 20 on the sides of the V-shaped positioning blocks 18 determines whether the pipe is properly clamped.

[0037] The base 13 is provided with a grinding mechanism position adjustment rack.

[0038] In actual use, after the robot places the pipe to be ground onto the equipment, the grinding wheel 16 on end A is first moved along the X-axis by the lateral translation machine 21. After grinding at one end, it returns and is then moved one station laterally along the Y-direction by the longitudinal translation machine 24. At this time, the grinding equipment 14 on the other end begins grinding at end B. Similarly, the grinding wheel 16 at end B moves along the X-direction. After grinding is completed, the equipment at end B retracts. During grinding, the air blowing mechanism 17 on the opposite end contacts the pipe opening to blow air in real time, preventing dust and debris from entering the pipe due to grinding.

[0039] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
