Description

Technical Field

[0001] The invention belongs to the field of engine manufacturing, and in particular relates to a multi-layer swing arm type brush tool for machining burrs of a main bearing hole of a cylinder body. Background Art

[0002] After the main bearing hole of the engine block is processed, the burrs around the bearing hole and the bearing cover need to be removed. The usual method for this phenomenon is to remove the bearing cover and manually remove the burrs one by one, using a scraper or a small electric grinding wheel to grind it. The disadvantage of this method is that the steps are cumbersome, and the surface of the bearing cover or the main shaft hole is easily scratched during the grinding process, which affects the assembly and use accuracy of the engine.

[0003] Among them, the patent number is: CN201811110110.8. This device can perform two processes at the same time by setting a positive chamfering tool, a reverse chamfering tool and a limit buffer component. However, this device can only process one layer of inner hole, and cannot meet the processing requirements of burrs on the upper and lower end surfaces of engine main bearing holes of various types and depths.

[0004] Therefore, it is particularly important to design a device that can perform multi-layer deburring, has strong adaptability and high deburring efficiency. Summary of the invention

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely explain the technical solutions in the embodiments of the present invention. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict, and the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0033] Referring to the accompanying drawings, this embodiment is described. A multi-layer swing-arm brush tool for machining burrs on a main bearing hole of a cylinder block comprises a tool handle 1, a main tool body 3, a tool body module 4 and a brush assembly. The main tool body 3 is disposed at the lower end of the tool handle 1. A plurality of tool body modules 4 are sequentially disposed at the lower end of the main tool body 3. A brush assembly with an adjustable position is disposed in the main tool body 3 along the up-and-down direction. Each tool body module 4 has an adjustable position brush assembly disposed in the up-and-down direction. Openings are disposed on both sides of the main tool body 3 and each tool body module 4. When the tool handle 1 rotates, each brush assembly rotates and extends out of the opening at the corresponding position.

[0034] In this embodiment, the shank 1 is connected to the main blade body 3 via a blade body connecting bolt 2. The detachable structure allows for replacement according to actual usage requirements and is applicable to a wide range of working conditions.

[0035] In this embodiment, a protrusion is arranged at the lower end of the tool handle 1, and a groove adapted to the protrusion is arranged at the upper end of the main tool body 3. Such a design can improve the accuracy of the alignment process and the alignment efficiency at the same time.

[0036] In this embodiment, each of the blade modules 4 includes two side panels 11 and a blade connection block 6, and the two side panels 11 are symmetrically arranged on both sides of the upper part of the blade connection block 6, and the upper end of each side panel 11 of the blade module 4 located at the lower side is connected to the blade connection block 6 of the adjacent upper blade module 4. Each of the side panels 11 is connected to the blade connection block 6 at the corresponding position through the module connection bolt 5, and the upper end of the side panel 11 of the blade module 4 arranged at the lower end of the main blade body 3 is connected to the main blade body 3 through the module connection bolt 5. Through this design, the appropriate number of blade modules 4 can be selected according to the use conditions, and they can be connected through the module connection bolt 5, thereby improving the convenience of installation and disassembly, and being able to adapt to the use conditions of multiple layers.

[0037] In this embodiment, the brush assembly includes a swing arm rod 7, a brush head 8, a swing arm shaft sleeve 9 and a swing arm shaft 10. The swing arm rod 7 is an eccentric structure and the lower end is the side with heavier weight. The brush heads 8 are arranged at the upper and lower ends of the swing arm rod 7. The swing arm rod 7 is rotatably connected to the swing arm shaft 10 through the swing arm shaft sleeve 9. The eccentric arrangement of the swing arm rod 7 can make the swing arm rod 7 extend from the opening at the corresponding position under the action of the eccentric force when the tool handle 1 rotates, and the brush head 8 cleans the burrs in conjunction with the rotation of the tool handle 1. The swing arm rod 7 can be extended efficiently without corresponding control.

[0038] In this embodiment, first slide grooves are symmetrically arranged along the vertical direction on both sides of the main blade body 3, and the swing arm 7 corresponding to the main blade body 3 is slidably arranged in the first slide groove and fixed by a nut. A second slide groove is arranged along the vertical direction on the side plate 11 of each blade module 4, and the swing arm 7 corresponding to the corresponding blade module 4 is slidably arranged in the second slide groove and fixed by a nut. By adjusting the position of the swing arm 7, the position of the swing arm 7 in each layer can be adjusted, thereby adjusting the distance between the swing arm 7 to adapt to the corresponding use conditions.

[0039] When in use, first determine how many knife body modules 4 should be installed in sequence under the main knife body 3 according to the number of layers of burrs that need to be cleaned. After the determination is completed, install them in sequence. After the installation is completed, determine the distance between each adjacent swing arm rod 7 according to actual usage requirements. After determining the position, lock the corresponding swing arm shaft 10 with a nut, thereby completing the installation and adjustment work before use.

[0040] The rotating tool handle 1 drives the main tool body 3 to rotate, thereby driving the various tool body modules 4 below to rotate. During the rotation, due to the eccentric structure of the swing arm rod 7, the swing arm rod 7 rotates and extends from the opening at the corresponding position during the rotation, so that the extended brush head 8 grinds the burrs to remove defects. When the cleaning is completed, the tool handle 1 is stopped. After the tool handle 1 stops rotating, the swing arm rod 7 will return to a vertical state with the heavier side facing downward. At this time, the rotating tool handle 1 can be lifted upward to complete the burr removal.

[0041] The embodiments of the present invention disclosed above are only used to help illustrate the present invention. The embodiments do not describe all the details in detail, nor do they limit the invention to the specific implementation methods described. According to the content of this specification, many modifications and changes can be made. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can understand and use the present invention well.
