Description

Technical Field

[0001] This utility model relates to the field of boring and milling machines, and more specifically, it relates to a tool changing mechanism applied to boring and milling machines. Background Technology

[0002] Boring and milling machines are commonly used in industrial production. They are used to bore holes in the interior of parts or mill the surface of parts, facilitating production and greatly simplifying industrial processes. During the boring and milling process, various cutting tools often need to be changed to achieve machining at different locations on the part. On existing boring and milling machines, especially non-CNC machines, the cutting tools often need to be changed manually by the operator. Therefore, all cutting tools need to be prepared before machining, but existing boring and milling machines lack a tool storage structure. This can lead to tool loss due to oversight during machining, affecting tool usage and part machining. Furthermore, the cutting tools need to be used in sequence during machining. Due to the lack of a tool fixing structure, operators need to memorize the tool usage sequence. If the operator's memory is faulty, it will affect part production. Summary of the Invention

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a tool changing mechanism for boring and milling machines, which has the following advantages:

[0017] 1. This utility model, by setting up a tool changing structure, allows the operator to find all the necessary tools according to the processing requirements before machining the parts. The tools are placed on the moving frame, and the adjusting rod is rotated according to the diameter of the tool. Through the threaded connection between the adjusting rod and the mounting plate, the rotating adjusting rod drives the fixed block to move. Thus, the tool is clamped and fixed by the cooperation of the two fixed blocks, which facilitates the stable placement of tools according to different tool sizes and facilitates contact and installation with the boring and milling machine body during tool changing.

[0018] 2. This utility model features multiple mounting slots on a rotating plate and movable frames within these slots. When fixing the cutting tool, the rotating plate is rotated according to the order of use, by engaging the rotating column at the lower end of the rotating plate with the rotating holes on the fixed frame. This causes the different movable frames to face outwards sequentially, thus allowing the cutting tool to be fixed onto different movable frames in sequence. This facilitates the installation and retrieval of the cutting tool, thereby simplifying the use of the boring and milling machine.

[0019] 3. This utility model uses an electric push rod on the base plate. When changing tools, the electric push rod drives the fixed frame and the rotating plate to rise, so that the rotating plate reaches a suitable height. Rotating the threaded rod, through the threaded connection between the threaded rod and the moving frame, drives the moving frame and the tool at the front end of the moving frame to move the tool to the center position of the rotating plate. This makes it easier to align the tool with the tool mounting position on the boring and milling machine body. By using existing tool mounting technology and structure, the tool is mounted on the boring and milling machine, thus facilitating tool installation. Attached Figure Description

The movable frame 6 is movably installed on the rotating plate 5.

[0031] In this embodiment, the main structure of the boring and milling machine is formed by the base plate 1, the support frame 2 and the boring and milling machine body 3.

[0032] More specifically, the tool changing structure facilitates tool changing and the placement and sequential use of tools.

[0033] Please see Figures 1-5As one embodiment of the tool changing structure: a notch 11 is provided on the support frame 2, and a mating piece 12 is fixedly provided at the lower end of the platform plate 4. The mating piece 12 and the notch 11 are mutually engaged. A sliding rod 13 is provided on the support frame 2 within the notch 11. There are two sliding rods 13, and both ends of the sliding rod 13 are threaded. The sliding rod 13 is threadedly connected to the contact position of the support frame 2. The sliding rod 13 passes through the mating piece 12, and the sliding rod 13 and the mating piece 12 are slidably connected. The mating piece 12 and the support frame 2 are slidably connected. A rotating column 14 is fixedly provided at the lower end of the rotating plate 5. A rotating hole 15 is provided on the fixed frame 9. The rotating column 14 and the rotating hole 15 are mutually engaged and rotatably connected. An installation groove 16 is provided on the rotating plate 5. Multiple mounting slots 16 are provided. The movable frame 6 is movably set in the mounting slots 16. Multiple fixed blocks 7 and multiple movable frames 6 are provided. The fixed blocks 7 are set on the movable frames 6. A threaded rod 17 is provided in the mounting slots 16. The threaded rod 17 is rotatably connected to the rotating plate 5. The threaded rod 17 passes through the movable frame 6. The movable frame 6 and the threaded rod 17 are threadedly connected. The front end of the movable frame 6 is fixedly provided with a mounting plate 18. An adjusting rod 19 is provided on the fixed block 7. The adjusting rod 19 is rotatably connected to the fixed block 7. The adjusting rod 19 is threaded.

The mounting holes 20 and the adjusting rods 19 are threadedly connected.

[0034] Specifically, before machining the parts, according to the order of use, the rotating plate 5 is rotated by the cooperation of the rotating column 14 at the lower end of the rotating plate 5 and the rotating hole 15 on the fixed frame 9. This causes the different moving frames 6 to face outwards in sequence, so that when installing the cutting tools, the tools are fixed onto the different moving frames 6 in sequence. The operator finds all the required tools according to the machining needs, places the tools on the moving frames 6, and rotates the adjusting rod 19 according to the diameter of the tool. Through the threaded connection between the adjusting rod 19 and the mounting plate 18, rotating the adjusting rod 19 drives the fixed block 7 to move, thereby clamping and fixing the tool through the cooperation of the two fixed blocks 7.

The tool is mounted on the boring and milling machine using existing tool mounting technology and structure.

[0035] In summary, when using it as a whole:

[0036] Before machining the parts, according to the order of use, the rotating plate 5 is rotated by the cooperation of the rotating column 14 at the lower end of the rotating plate 5 and the rotating hole 15 on the fixed frame 9, so that the different moving frames 6 face outward in sequence. Thus, when installing the tool, the tool is fixed on the different moving frames 6 in sequence. The operator finds all the required tools according to the machining needs, places the tools on the moving frames 6, and rotates the adjusting rod 19 according to the diameter of the tool. Through the threaded connection between the adjusting rod 19 and the mounting plate 18, the rotating adjusting rod 19 drives the fixed block 7 to move, so that the tool is clamped and fixed by the cooperation of the two fixed blocks 7, which makes it easy to place the tool stably according to different tool sizes.

[0037] When changing tools, pull the platform plate 4. Through the sliding connection between the mating piece 12 and the slide rod 13, the platform plate 4 no longer obstructs the missing hole. The electric push rod 8 drives the fixed frame 9 and the rotating plate 5 to rise, so that the rotating plate 5 reaches the appropriate height. Rotate the threaded rod 17. Through the threaded connection between the threaded rod 17 and the moving frame 6, the moving frame 6 and the tool at the front end of the moving frame 6 are moved, so that the tool moves to the center position of the rotating plate 5. This makes it easy to align the tool with the tool mounting position of the boring and milling machine body 3. The tool is mounted on the boring and milling machine using existing tool mounting technology and structure.
