DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-4 A hollow tube wall grinding mechanism for automobile shock absorber comprises a workbench 1, an active roller 2 and a driven roller 3 are symmetrically arranged on the upper surface of the workbench 1, a first hydraulic cylinder 6 is arranged on a fixed frame on a side of the driven roller 3 away from the active roller 2, a hollow tube 4 is placed between the active roller 2 and the driven roller 3 on both sides, and a pressing mechanism 7 is arranged on the upper part between the active roller 2 and the driven roller 3 on both sides, and the pressing mechanism 7 is installed at the bottom end of the output end of the first hydraulic cylinder 6, a moving mechanism 8 is arranged on the upper surface of the workbench 1 on one side of the driven roller 3, and a grinding unit 9 is installed on the moving mechanism 8;

[0021] The pressing mechanism 7 includes a mounting plate 71 , and a pressing frame 72 is symmetrically mounted on the bottom surface of the mounting plate 71 , and the pressing frame 72 is fixed by a fixing component 10 , and the upper surface of the mounting plate 71 is arranged at the bottom end of the output end of the first hydraulic cylinder 6 .

[0022] Among them, a first motor 5 is connected and installed on the rotating frame on one side of the active roller 2. The output end of the first motor 5 is assembled and connected with the active roller 2, and drives the active roller 2 to rotate with the output end of the first motor 5 as the axis. The first motor 5 can effectively drive the hollow tube 4 to rotate, so that the rotation of the hollow tube 4 can be realized under the cooperation of the driven roller 3 on one side and the pressing mechanism 7 above.

[0023] Among them, a plurality of mounting holes 711 are symmetrically opened on the mounting plate 71, and the fixing component 10 can be installed at the mounting hole 711, and the mounting hole 711 is used to install the pressing frame 72 at the bottom. The plurality of mounting holes 711 can adjust the spacing between the pressing frames 72 on both sides to adapt to hollow tubes 4 with different diameters.

[0024] In addition, bolt holes 721 are symmetrically provided on the upper surface of the pressing frame 72, and the fixing component 10 can be installed and screwed into the bolt hole 721, and the bolt hole 721 is aligned with the center of the installation hole 711. Silicone rollers 722 are rotatably provided at the two side ends of the bottom of the pressing frame 72. The silicone rollers 722 can cooperate with the first hydraulic cylinder 6 to effectively press on the body of the hollow tube 4, thereby preventing the hollow tube 4 from rolling down and venting air from between the active roller 2 and the driven roller 3, thereby playing a limiting role.

[0025] In addition, the moving mechanism 8 includes a guide rail 82, on the upper surface of which a moving bracket 81 is slidably provided, and a grinding unit 9 is mounted on the moving bracket 81. The moving bracket 81 can move slowly on the guide rail 82, so as to send the grinding unit 9 into the inner wall of the hollow tube 4 to grind the inner wall.

[0026] In addition, the grinding unit 9 includes a second hydraulic cylinder 91 , a second motor 92 is installed at the bottom end of the output end of the second hydraulic cylinder 91 , a grinding head 93 is installed on the output end of the second motor 92 , and the grinding head 93 rotates under the drive of the second motor 92 to grind the inner wall of the hollow tube 4 .

[0027] In the present embodiment, when it is necessary to grind the inner wall of a batch of hollow tubes 4 of the same size, the present equipment can be used. First, the hollow tube 4 is placed between the roller bodies of the active roller 2 and the driven roller 3. Then, the pressing mechanism 7 is pressed downward by using the first hydraulic cylinder 6 so that the silicone roller 722 can contact and press the hollow tube 4. Then, whether the silicone rollers 722 on both sides can press the hollow tube 4 while preventing it from falling off is checked. The active roller 2 and the driven roller 3 at the bottom are driving, and their spacing does not need to be controlled. However, by controlling the spacing of the silicone rollers 722 on both sides above, the pressing mechanism 7 can press the hollow tubes 4 of different diameters, which can effectively play the role of limited pressing. If the spacing is not enough, the fixing component 10 can be removed, and then the pressing frames 72 of the silicone rollers 722 on both sides are symmetrically installed at suitable mounting holes 711, and the bolt holes 721 are aligned with the mounting holes 711. Then, the fixing component 10 can be installed to fix the pressing frames 72 on both sides.

[0028] When starting to grind, the pressing mechanism 7 now presses and limits the hollow tube 4, and then the grinding unit 9 can be adjusted to a suitable position by adjusting the moving mechanism 8 on one side, and the moving bracket 81 slowly moves toward the hollow tube 4 on the guide rail 82, and the grinding head 93 now slowly moves toward the inner wall of the hollow tube 4. When the grinding head 93 moves to the inner wall of the hollow tube 4, the second hydraulic cylinder 91 can be driven to move the grinding head 93 up and down to ensure that the grinding head 93 can contact the inner wall of the hollow tube 4, thereby performing the grinding work.

[0029] And the grinding head 93 can be replaced, and the first motor 5 has a slow rotation speed, which is suitable for low-speed grinding. The first motor 5 drives the active roller 2 to rotate, thereby cooperating with the driven roller 3 and the upper silicone roller 722 to make the hollow tube 4 rotate at a low speed, while the grinding head 93 does not rotate, so that the grinding head 93 performs grinding work at a low speed, and the second motor speed 92 is faster, which is suitable for driving the grinding head 93 to rotate at a high speed for high-speed grinding. When the movable bracket 81 moves on the guide rail 82, so that the grinding head 93 has completely polished the tube wall, the movable bracket 81 can be retracted, so that the grinding unit 9 is pushed out, and then the pressing mechanism 7 is raised, and the hollow tube 4 is considered to have completed grinding.

[0030] In the utility model, the grinding unit 9 is provided in cooperation with the moving mechanism 8, so that the grinding of the pipe wall can be realized automatically, and the first motor 5 and the second motor 6 can realize the grinding work at different speeds, which can effectively replace manual grinding and effectively improve the work efficiency. Moreover, the pressing mechanism 7 is adjustable, and by changing the spacing between the pressing frames 72 on both sides, the silicone roller 722 can effectively press and limit the hollow pipes 4 of different sizes, so that the grinding equipment can be suitable for hollow pipes 4 of different sizes.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
