Description

Technical Field

[0001] This utility model relates to the field of valve plate processing technology, specifically a machine tool for valve plate processing. Background Technology

[0002] The processing of metal valve plates requires circumferential machining using machine tools. Especially when machining stainless steel valve plates, existing valve plate machining machine tools require different tools for different positions, necessitating manual tool changes. This tool change process not only requires a certain amount of operating space but also takes a relatively long time. Therefore, we need to design a valve plate machining machine tool that facilitates tool changes, improves tool change efficiency, requires less operating space, and enhances the overall space utilization of the structure.

[0011] (III) Beneficial Effects

[0012] Compared with the prior art, this utility model provides a machine tool for processing valve plates, which has the following beneficial effects:

[0013] This valve plate machining machine tool uses a valve plate rotation structure to easily fix the valve plate and rotate it in front of the machining motor. The machining motor, which can move forward, backward, left, and right, facilitates the machining of one of the cutting heads on the valve plate. The tool changing structure, through a rotating frame that can move forward and backward and rotate on its own axis, allows for easy movement and repositioning of two tool holders. During forward and backward movement, the tool holders are easily installed at the output end of the machining motor. The tool changing rotary motor rotates the tool head holder, facilitating the replacement of the cutting head on the other tool holder. This valve plate machining machine tool facilitates tool changing, improving efficiency while requiring minimal operating space, thus increasing the overall space utilization of the structure.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example:

[0020] Please see Figure 1-3 A valve plate machining machine tool includes a machine frame 1 and multiple cutting heads 20. The machine frame 1 is equipped with a machining motor 4 that can move back and forth and left and right. The output end of the machining motor 4 is fixedly installed with a locking part adapted to the cutting head 20. A valve plate rotating structure is provided on the side of the machine frame 1 opposite to the machining motor 4. A tool changing structure is provided on the machine frame 1 located on the side of the machining motor 4. The tool changing structure includes a tool changing frame 11 fixedly installed on the machine frame 1. A tool disc frame 12 with multiple circumferentially adapted to the cutting head 20 is rotatably connected to the tool changing frame 11 via a tool changing rotary motor 13. A rotating frame 14 perpendicular to the tool disc frame 12 is also provided on the tool changing frame 11. Tool holders 15 adapted to the cutting head 20 are fixedly installed at both ends of the rotating frame 14. The rotating frame 14 can move back and forth and rotate.

[0021] Specifically, a telescopic rotating shaft 16 is fixedly installed in the middle of the rotating frame 14 and is slidably engaged with the tool changer 11. The tool changer 11 also includes a feed drive mechanism for driving the telescopic rotating shaft 16 to move back and forth and a switching drive mechanism for driving the telescopic rotating shaft 16 to rotate. The feed drive mechanism facilitates the overall feeding movement of the telescopic rotating shaft 16 and the rotating frame 14. The switching drive mechanism facilitates the overall rotation of the telescopic rotating shaft 16 and the rotating frame 14.

[0022] Specifically, the feed drive mechanism includes a telescopic drive cylinder 18 fixedly mounted on the tool changer 11, and the switching drive mechanism includes a switching motor 17 fixedly mounted on the tool changer 11. A transmission roller is rotatably connected to the tool changer 11 and engages with the telescopic rotating shaft 16. The output shaft of the switching motor 17 is fixedly connected to the transmission roller, and a rotating sleeve is fixedly mounted on the output shaft of the switching motor 17. A rotating seat is rotatably and slidably fitted on the rotating sleeve. One end of the telescopic rotating shaft 16 away from the rotating frame 14 is fixedly connected to the rotating seat. When the telescopic drive cylinder 18 is activated, the transmission roller is driven to rotate. Through the engagement and sliding cooperation between the transmission roller and the telescopic rotating shaft 16, the telescopic rotating shaft 16 is driven to rotate synchronously. Through the telescopic drive cylinder 18, the telescopic rotating shaft 16 and the rotating frame 14 are moved back and forth as a whole under the action of the rotating sleeve and the rotating seat.

[0023] Specifically, the valve plate rotation structure includes a suction cup 2 rotatably connected to the machine tool frame 1, and a limiting plate 3 opposite to the suction cup 2 and capable of feeding towards the suction cup 2. A rotary drive motor 5 is fixedly installed on the machine tool frame 1, and a transmission shaft 19 is fixedly installed on the end of the suction cup 2 away from the limiting plate 3. The rotary drive motor 5 and the transmission shaft 19 are connected by a transmission assembly. Furthermore, the limiting plate 3 can be fed by a feed drive cylinder, thereby clamping the valve plate between the limiting plate 3 and the suction cup 2. Before the valve plate is rotated and before processing, the valve plate can be pressed onto the suction cup 2 by the limiting plate 3, improving the stability during processing. Furthermore, the transmission assembly can adopt a sprocket and chain or belt and pulley transmission form, preferably a sprocket and chain transmission form. Starting the rotary drive motor 5 facilitates the rotation of the transmission shaft 19 and the suction cup 2 as a whole, so that the suction cup 2 can drive the valve plate to rotate while holding the valve plate.

[0024] Specifically, a feed guide rail 6 is fixedly installed on the machine tool frame 1, a feed slide 7 is guided and slidably fitted on the feed guide rail 6, and a translation slide block 8 is guided and slidably fitted on the feed slide block 7. The machining motor 4 is fixedly installed on the translation slide block 8. The machine tool also includes a feed drive motor 9 that drives the feed slide block 7 to feed on the feed guide rail 6 and a translation drive motor 10 that drives the translation slide block 8 to move laterally on the feed slide block 7. The feed drive motor 9 is fixedly installed on the machine tool frame 1, and the translation drive motor 10 is fixedly installed on the feed slide block 7. Furthermore, the output shafts of the feed drive motor 9 and the translation drive motor 10 are both fixedly installed with screws, and adjusting blocks are slidably fitted on the screws. The adjusting block located on the side of the feed drive motor 9 is fixedly connected to the feed slide block 7, and the adjusting block located on the side of the translation drive motor 10 is fixedly connected to the translation slide block 8.
