Description

Technical Field

[0001] This utility model relates to the field of bushing boring technology, and in particular to bushing boring equipment that facilitates quick tool changes. Background Technology

[0002] In modern manufacturing, bushings are core components for mechanical transmission and support, and are widely used in the automotive, construction machinery, and aerospace industries. With the acceleration of industrialization, the market has placed increasingly higher demands on the precision, efficiency, and mass production capabilities of bushings. As a key process for precision machining of the inner hole of bushings, boring directly affects the assembly performance and service life of bushings. Therefore, bushing boring equipment has become an important basic equipment in the field of mechanical manufacturing.

[0003] Traditional bushing boring equipment consists of a bed, spindle box, feed system, fixture, and boring tool assembly. The spindle box drives the boring tool to rotate, achieving the cutting motion. The feed system controls the relative movement between the tool and the workpiece to control the boring depth. The fixture is used to position and clamp the bushing workpiece to ensure machining stability. However, in actual production, when machining bushings of different specifications and with different precision requirements, it is necessary to frequently change the boring tool to adapt to different hole diameters, machining accuracies, and material properties. In this case, the tool changing process of traditional equipment often relies on manual disassembly and installation of the tool. However, the existing technology for boring tools is cumbersome and time-consuming. To address these drawbacks, existing technologies utilize mechanical structure optimization to achieve rapid tool changing in bushing boring machines. These machines employ standardized positioning interfaces between the tool holder and the spindle, such as tapered fits and end-face key positioning structures, along with manual and semi-automatic locking devices. By using preset mechanical positioning benchmarks, they ensure consistent tool installation and reduce the time spent on manual centering adjustments. However, existing technologies cannot quickly disassemble and install boring tools of different sizes, resulting in low flexibility. Furthermore, they cannot clean up debris, limiting their practicality. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a bushing boring machine that facilitates quick tool changing, aiming to improve the problems of existing technology that cannot quickly disassemble and install boring tools of different sizes, has low flexibility, cannot clean up debris, and has low practicality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a bushing boring machine for easy and quick tool changing, comprising a mounting shell, a sliding plate slidably connected to the top of the mounting shell, a base fixedly connected to the bottom of the mounting shell, a replacement mechanism provided on the inner wall of the mounting shell, and a cleaning mechanism provided at the bottom of the inner wall of the mounting shell, the cleaning mechanism being used for cleaning;

[0006] The replacement mechanism includes a protective shell, the left side of which is fixedly connected to the left side of the inner wall of the mounting shell, an asynchronous motor is fixedly connected to the inner wall of the protective shell, a gear is fixedly connected to the output end of the asynchronous motor, and a rotating component is provided on the outer wall of the gear.

[0007] As a further description of the above technical solution:

[0008] The cleaning mechanism includes an asynchronous motor II, the right side of which is fixedly connected to the right side of the inner wall of the mounting housing. The output end of the asynchronous motor II is fixedly connected to a coupling for connection. A guide post is fixedly connected to the right side of the inner wall of the mounting housing. A moving component is provided on the left side of the coupling.

[0009] As a further description of the above technical solution:

[0010] The rotating assembly includes a second gear, the outer wall of which meshes with the outer wall of a first gear, a connecting column is fixedly connected to the inner wall of the second gear, a support plate is rotatably connected to the outer wall of the connecting column, and a rotating assembly is provided on the right side of the connecting column.

[0011] As a further description of the above technical solution:

[0012] The rotating assembly includes a threaded post, the left side of which is fixedly connected to the right side of the connecting post. A threaded sleeve is threadedly connected to the outer wall of the threaded post, and a limit assembly is provided on the inner wall of the threaded post.

[0013] As a further description of the above technical solution:

[0014] The limiting component includes a limiting post, the outer wall of which is fixedly connected to the inner wall of the threaded post. The right side of the limiting post has multiple limiting holes, and the inner wall of the limiting holes is provided with a locking component.

[0015] As a further description of the above technical solution:

[0016] The locking assembly includes a locking block, the outer wall of which is slidably connected to the outer wall of the limiting hole, a wedge block fixedly connected to the top of the locking block, and a boring tool slidably connected to the inner wall of the limiting post.

[0020] The cleaning assembly includes a connecting plate, the rear side of which is fixedly connected to the outer wall of a circular plate, and a plurality of brush heads are fixedly connected to the bottom of the connecting plate.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the boring tool is inserted into the limiting post, and then the threaded sleeve is rotated. Since the inner wall of the threaded sleeve is threaded, it will move along the outer wall of the limiting post, thereby squeezing the wedge blocks on both sides, causing the locking block to enter the limiting hole and applying pressure to the boring tool, thus achieving quick installation. When disassembly is required, simply rotate the threaded sleeve in the opposite direction to release the constraint on the wedge blocks, and the boring tool can be easily removed. This not only enables quick replacement of the boring tool, but also adapts to different sizes of cutting edges, greatly improving practicality.

Since the inner wall of the circular plate has a threaded structure, it can drive the circular plates on both sides to move left and right. At the same time, the connecting plate drives multiple brush heads to clean the inner wall of the mounting shell, avoiding debris residue and further enhancing practicality.

[0041] Working principle: By inserting the boring bar 2073 into the limiting post 2061, and then rotating the threaded sleeve 2052, the inner wall of the threaded sleeve 2052 is threaded, so the threaded sleeve 2052 moves along the outer wall of the limiting post 2061, which compresses the wedge blocks 2072 on both sides, allowing the locking block 2071 to enter the limiting hole 2062 and compress the boring bar 2073, thus achieving quick installation. When disassembly is required, the threaded sleeve 2052 is screwed in the opposite direction to release the restriction on the wedge blocks 2072, and the boring bar 2073 can be taken out. This achieves the function of quick replacement of the boring bar 2073 and can adapt to different sizes of cutting edges, thus enhancing its practicality.

[0042] By turning on the asynchronous motor 301, the threaded rod 3041 is driven to rotate through the coupling 303. The inner wall of the circular plate 3042 is threaded, so the circular plates 3042 on both sides are moved left and right. At the same time, the connecting plate 3051 drives multiple brush heads 3052 to clean the inner wall of the mounting shell 1, preventing debris residue and enhancing practicality.
