[0002] Against the backdrop of rapid railway development, the railway parts industry has also maintained a relatively high level of development. The localization of equipment is one of the trends in railway parts manufacturing. Milling machines are needed for milling in the manufacturing process of railway parts, and milling machines for railway parts processing are widely used in the field of railway parts processing.

[0003] In actual production, operators need to place the railway parts to be processed on the milling machine table and fix them in place. However, the existing milling machine table is usually a fixed size structure, which will result in a large area of ​​the table being idle when processing small railway parts. However, when the parts need to be moved and adjusted, the entire table must be moved, resulting in increased ineffective energy consumption. The top of the table usually has a groove structure, but metal shavings and coolant generated during processing are easy to accumulate in it, which seriously affects the cleaning and maintenance efficiency of the table. Based on this, this application proposes a milling machine for processing railway parts. Utility Model Content

[0016] This utility model provides an embodiment: Please refer to Figures 1-6 A milling machine for processing railway parts includes a base 1, a fixing block 2 on one side of the top of the base 1, and a lifting and translating structure on the top of the fixing block 2. The fixing block 2 is connected to a worktable for placing railway parts via the lifting and translating structure. A milling machine body 3 for processing railway parts is located on the other side of the top of the worktable. The milling machine body 3 adopts a conventional milling machine structure design, possessing the basic functions of a conventional milling machine to meet the conventional processing needs of railway parts. This application focuses on improving the worktable structure; therefore, the specific structure of the milling machine body 3 will not be described in detail. The milling machine body 3 is connected to the base 1 via a telescopic structure 17. Under the action of the telescopic structure 17, the distance between the milling machine body 3 and the worktable can be changed, facilitating the processing of railway parts by the milling machine body 3.

[0017] The workbench has a modular structure, including several L-shaped plates 4. In two adjacent plates 4, the horizontal end of one plate 4 contacts the vertical end of the other, forming a groove between them. A lifting plate 8 is movably connected within this groove. A scraper ring is provided on the outer wall of the lifting plate 8, which contacts the inner wall of the groove. The lifting plate 8 is connected to the workbench via a first lifting structure 10. Under the action of the first lifting structure 10, the position of the lifting plate 8 can change. When the lifting plate 8 moves, it can scrape away impurities adhering to the inner wall of the groove, improving the ease of cleaning the groove and thus increasing the cleaning efficiency of the workbench. Furthermore, when there is a large unused area on the workbench, the lifting plate 8 can be used to seal grooves far from railway parts, preventing processing debris and cooling lubricating oil from splashing into the groove, reducing blind spots in cleaning, and further improving the cleaning efficiency of the workbench.

[0018] A connecting plate 5 is provided at the bottom of the platform 4. The length of the connecting plate 5 is the same as the length of the platform 4. The connecting plate 5 is connected to the fixed block 2 through a lifting and sliding structure. The number of lifting and sliding structures is the same as the number of connecting plates 5. A limit groove 6 is provided in the middle of the bottom of the connecting plate 5. A fixed groove 9 is provided at both ends of the limit groove 6.

[0019] The top of the fixed block 2 is provided with a receiving groove 12. The lifting and translating structure includes a second lifting structure 15 and a translating structure 11 connected to the bottom of the receiving groove 12. Both ends of the receiving groove 12 are provided with translating structures 11. The extension and retraction directions of the two translating structures 11 are opposite. The translating structure 11 is connected to the fixed block 2 through the second lifting structure 15. The output shaft end of the translating structure 11 is connected to a moving block 7. The top of the moving block 7 is provided with a limiting block 13 adapted to the limiting slide 6. The middle of the limiting block 13 is movably connected to a fixed column 14. The fixed column 14 is adapted to the fixed groove 9. The fixed column 14 is connected to the moving block 7 through a third lifting structure 16. The moving block 7 is located outside the receiving groove 12, and the top of the moving block 7 is at the same height as the bottom of the connecting plate 5.

[0020] In use, the position of the fixed column 14 can be changed under the action of the third lifting structure 16. When the fixed column 14 is inserted into the fixed slot 9, the translation structure 11 adapted to the fixed column 14 works. The translation structure 11 drives the table plate 4 to move through the moving block 7, the limiting block 13, the fixed column 14 and the connecting plate 5 connected to the fixed column 14, so as to realize the feed movement of the table plate 4 in the X-axis direction. The extension and retraction of the second lifting structure 15 can realize the feed movement of the table plate 4 in the Z-axis direction. Under the action of the extension and retraction structure 17, the position of the table plate 4 in the Y-axis direction and the position of the milling machine body 3 can be changed, so as to facilitate the processing of railway parts by the milling machine body 3.

[0021] As can be seen from the above description, when using this application, the number of movable platforms can be controlled as needed to avoid increasing energy consumption by moving idle platforms.

[0024] In summary: When using this milling machine for processing railway parts, after the railway parts to be processed are fixed on the worktable, the operator controls the extension of the third lifting structure 16 according to the requirements. The third lifting structure 16 drives the fixed column 14 connected to it to move until the fixed column 14 and the fixed groove 9 are engaged, so that the table plate 4 adapted to the railway parts to be processed is connected to the fixed block 2 through the lifting and translation structure below it. During the processing of railway parts, the lifting and translation structure can be used to feed the railway parts in the X-axis or Z-axis direction, and the telescopic structure 17 can be used to change the position of the milling machine body 3 in the Y-axis direction, which is convenient for the milling machine body 3 to process the railway parts.
