DETAILED DESCRIPTION

[0027] like Figures 1 to 6 As shown, the present invention discloses an intelligent grinding device for brake oil pipes, including a grinding frame 1, an oil pipe clamping assembly 2 and a cutting and grinding assembly 3 installed on the grinding frame 1. The grinding frame 1 is a grinding platform installed on the ground. By being fixed on the ground, the vibration of the brake oil pipe during grinding can be transmitted to the ground to reduce errors. The brake oil pipe is a straight pipe. The oil pipe clamping assembly 2 is located on one side of the brake oil pipe and is used to clamp the brake oil pipe. The cutting and grinding assembly 3 is used to cut and grind the clamped brake oil pipe. A thickness detection device for the brake oil pipe is installed on the grinding frame 1. When it is detected that the thickness of the brake oil pipe is cut to a certain thickness, the grinding component 8 is used to grind the brake oil pipe again, thereby achieving the purpose of intelligent grinding and improving the efficiency and accuracy of grinding. The oil pipe clamping assembly 2 can be any one of the conventional round pipe clamps for clamping, which is used to clamp the brake oil pipe during processing.

[0028] Among them, the cutting and grinding assembly 3 disclosed in the present invention includes a first motor 4, a transmission shaft 5 connected to the output end of the first motor 4, and a grinding head 6 connected to the transmission shaft 5. Of course, the first motor 4 can also be other rotating drive devices that drive the transmission shaft 5 to rotate. The grinding head 6 is located at one end of the brake oil pipe. When the first motor 4 is started, it can drive the grinding head 6 to rotate around its axis to remove the excess from the brake oil pipe by cutting or grinding.

[0029] Specifically, the grinding head 6 disclosed in the present invention includes a barrel 7 and a plurality of grinding parts 8 evenly distributed on the surface of the barrel 7. The barrel 7 is in the shape of a straight cylinder, and its axis is parallel to the horizontal plane. Of course, the barrel 7 can also be in other shapes. Generally speaking, the cylindrical barrel 7 has a more uniform mass distribution in the circumferential direction, which can reduce eccentric vibration. An open groove 9 is provided on the outer side of the barrel 7. The open groove 9 extends along the axial direction of the barrel 7. The open groove 9 is rectangular or in other shapes. The rectangular open groove 9 can have a small gap with the extended support tube 10, thereby reducing the entry of dust during grinding.

[0030] A support tube 10 is installed in the open groove 9. The support tube 10 can be displaced along the radial direction of the cylinder body 7. Therefore, the support tube 10 can extend out or extend into the open groove 9 in the radial direction. When extending in, the grinding component 8 works, and when extending, the cutting component works. A cutting component 11 is installed in the support tube 10. The cutting edge of the cutting component extends from an open slit 12 opened on the surface of the support tube 10. The open slit 12 extends along the axial direction of the support tube 10. A radial displacement control component is installed in the cylinder body 7. The radial displacement control component can drive the support tube 10 to move radially along the cylinder body 7. By displacing the support tube 10 together with the cutting component, the cutting allowance can be adjusted at any time, and the processing requirements can be guaranteed without affecting the grinding component.

[0031] In this embodiment, the cutting component 11 includes a fixed tooth plate 13 fixed in the support tube 10, and first cutting teeth 14 fixed on the fixed tooth plate 13 at uniform intervals along the axial direction of the support tube 10. The fixed tooth plate 13 is long and its width is smaller than the radius of the support tube 10. The first cutting teeth 14 are triangular in shape and are integrally formed with the fixed tooth plate 13. The first cutting teeth 14 can be other shapes with sharp corners, but it is clear that there must be a gap between two adjacent first cutting teeth 14.

[0032] A movable tooth plate 15 is installed on one side of the fixed tooth plate 13. The movable tooth plate 15 is adjacent to the fixed tooth plate 13, and the two can be relatively displaced in an axially staggered manner. Second cutting teeth 16 are evenly spaced and fixed on the movable tooth plate 15 along the axial direction of the support tube 10. The structure of the second cutting teeth 16 can be the same as the shape of the first cutting teeth 14. The two can overlap in the normal direction, or they can be staggered with each other under the movement of the movable tooth plate 15, thereby increasing the density of the cutting blade and obtaining a faster cutting speed. Of course, this speed is obtained by sacrificing the rotational torque of the transmission shaft 5. At this time, the cutting amount should not be too large to avoid causing the tool to get stuck. The movable tooth plate 15 is connected to the axial displacement control component, which can drive the movable tooth plate 15 to move along the axis of the support tube 10 to change the axial spacing between the second cutting teeth 16 and the first cutting teeth 14. By adjusting the axial spacing between the second cutting teeth 16 and the first cutting teeth 14, the density of the cutting blades can be adjusted to meet the needs of different cutting speeds and precisions, so as to meet actual needs and have better adaptability.

[0033] In this embodiment, the axial displacement control assembly includes a second motor 17, a first connecting rod 18, a swing rod 19, a pin 20, and a second connecting rod 21. The second motor 17 can adopt other rotation drive mechanisms. The second motor 17 is fixed in the support tube 10. The output end of the second motor 17 is connected to the eccentric wheel 22. The eccentric shaft of the eccentric wheel 22 is hinged to one end of the first connecting rod 18. The other end of the first connecting rod 18 is hinged to one end of the second connecting rod 21 through the swing rod 19. The other end of the second connecting rod 21 is hinged to the movable tooth plate 15. The middle part of the swing rod 19 is rotatably connected to the support tube 10 through the pin 20. When the second motor 17 rotates, the eccentric shaft of the eccentric wheel 22 drives the swing rod 19 to swing through the first connecting rod 18, and the upper end of the swing rod 19 drives the movable tooth plate 15 to move through the second connecting rod 21. By adopting the above method, the axial interval between the second cutting tooth 16 and the first cutting tooth 14 can be automatically adjusted, and the adjustment is more convenient.

[0034] In this embodiment, the radial displacement control assembly includes a mounting plate 23, a third motor 24, a rotating plate 25, a third connecting rod 26, a slider 27, and a guide rail 28. In this embodiment, the mounting plate 23 is circular. In other embodiments, the mounting plate 23 may also be in other shapes besides circular, but the mounting plate 23 is perpendicular to the axis of the cylinder 7. The mounting plate 23 is fixed to the inner side of the cylinder 7, the third motor 24 and the guide rail 28 are mounted on the mounting plate 23, the output end of the third motor 24 is connected to the rotating plate 25, the outer circumference of the rotating plate 25 is connected to the slider 27 through the third connecting rod 26, the slider 27 is slidably arranged on the guide rail 28, the guide rail 28 is arranged along the radial direction of the mounting plate 23, and the slider 27 is connected to the support cylinder 10. When the third motor 24 rotates, the rotating plate 25 drives the slider 27 to move on the guide rail 28 through the third connecting rod 26, so as to realize the displacement control of the support cylinder 10, which is convenient to control and can realize intelligent adjustment.

[0035] In this embodiment, the grinding assembly includes a grinding buckle 29, both ends of which are fixedly connected to the cylinder 7, the plane where the grinding buckle 29 is located is perpendicular to the axis of the cylinder 7, and a grinding ring 30 is installed on the grinding buckle 29, and an abrasive 31 is installed on the grinding ring 30. The grinding ring 30 is slidably installed on the grinding buckle 29, and the grinding rings 30 at both ends of the grinding buckle 29 are respectively connected to the cylinder 7 through springs 32. The spring 32 provides elastic support force for the grinding ring 30, reduces the possibility of the grinding ring 30 getting stuck on the grinding buckle 29, and can improve the uniformity of grinding.

[0036] In this embodiment, a cleaning wheel 33 is coaxially mounted on the transmission shaft 5. The cleaning wheel 33 is located on the side away from the oil pipe clamping assembly 2, so that the grinding dust can be cleaned in time to reduce the influence of the dust on the grinding accuracy.

[0037] In this embodiment, the oil pipe clamping assembly 2 includes a support seat 34, a column 35, an arc-shaped pressure plate 36, a first telescopic device 37 and a second telescopic device 38. The support seat 34 is horizontally arranged on the upper side of the grinding machine frame 1. A semicircular groove 39 for installing the brake oil pipe is provided on the upper side of the support seat 34. One end of the support seat 34 is hinged to the column 35 fixed on the grinding machine frame 1, and the other end of the support seat 34 is connected to the output end of the first telescopic device 37. The first telescopic device 37 and the second telescopic device 38 are both installed on the grinding machine frame 1. The output end of the second telescopic device 38 is connected to the arc-shaped pressure plate 36, and the arc-shaped pressure plate 36 presses the brake oil pipe in the semicircular groove 39. By changing the telescopic length of the first telescopic device 37, the support angle of the support seat 34 can be adjusted to meet the actual grinding needs, which can improve the grinding efficiency.

[0038] In this embodiment, a through hole 40 is formed at one end of the cylinder 7 away from the first motor 4, an oblique hole 41 is formed on the cylinder 7, and a positive pressure gas generating device 42 is installed on the mounting seat at the same time. The positive pressure gas generating device 42 is connected to an exhaust hose 43, which passes through the brake oil pipe and is inserted into the through hole 40. By introducing gas into the inner side of the brake oil pipe, dust can be blown away in time, reducing the influence of dust on the grinding accuracy.

[0039] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it.
