[0029] A double-head vertical machining center, such as Figure 1 and Figure 2 As shown, it includes a base 10, a slide 11 movably installed on the top surface of the base 10, and a milling head is also installed on the top surface of the base 10. Specifically, a column is vertically installed on the top surface of the base 10, and two screws are rotatably connected to the wall of the column. Two connecting seats are also installed on the wall of the column. The two screws are respectively threadedly connected to the two connecting seats, and a milling head is installed on the top of each connected seat. The milling head is the prior art disclosed in the prior art, and its specific model and specifications are not limited too much here. Of course, the wall of the base 10 also has a tool magazine disclosed in the prior art, and another screw is horizontally installed on the top surface of the base 10. The screw is threadedly connected to the slide 11 to push the slide 11 to slide. A workbench is installed on the top surface of the slide 11, and the workpiece is fixed on the workbench. This is the prior art and will not be repeated here.
[0030] like Figure 2 , Figure 3 and Figure 4 As shown, the bottom of the slide 11 is provided with a slag discharge structure for cleaning the processing debris, and the slag discharge structure includes a bottom plate 20, a sliding body 21 and a scraping body 22. The bottom of the slide 11 is detachably connected to two bottom plates 20 distributed in a V shape, and the bottom of each bottom plate 20 is elastically connected to a plurality of sliding bodies 21. The bottom of each sliding body 21 is detachably connected to a scraping body 22, and the bottom surface of the scraping body 22 forms a comb tooth structure. The scraping body 22 can resist the base 10 and squeeze out the debris. By setting two The base plates 20 are distributed in a V shape. During the sliding process of the slide 11, a number of sliding bodies 21 at the bottom of the two base plates 20 push the corresponding scraping bodies 22 to contact the top surface of the base 10 and the screw driving the slide 11 to slide, so as to realize the cleaning of the debris on the top surface of the base 10. The two base plates 20 distributed in a V shape can make the debris be discharged to the two sides of the base 10 during the pushing process, thereby promoting the removal of debris from the top surface of the base 10, which has the effect of cleaning and centralized discharge.
[0031] like Figure 5 and Figure 5 As shown, a sliding channel 23 is provided on the bottom surface of the bottom plate 20, and the sliding body 21 is located in the sliding channel 23. An elastic member is provided in the sliding channel 23 to push the sliding body 21 downward. The bottom plate 20 forms a rectangular rod structure, and the side wall of the bottom plate 20 is provided with an integrally formed retaining edge. The wall surface of the retaining edge is provided with a mounting hole, and a bolt is provided in the mounting hole. The bolt is threadedly connected with the slide 11 to lock and fix the bottom plate 20. The sliding body 21 forms a block structure adapted to the sliding channel 23. The sliding body 21 is slidably connected with the sliding channel 23. The elastic member is installed on the top of the sliding body 21. The elastic member includes a spring but is not limited to a spring. In addition to the above scheme, a sliding channel 23 is provided, and the elastic member in the sliding channel 23 is used to squeeze and push the scraper 22. The elastic member is a spring for example, and the two ends of the spring are fixedly connected to the top surface of the scraper 22 and the top surface inside the sliding body 21 respectively, so as to ensure that each sliding body 21 can slide down individually and approach the top surface of the base 10. For the unevenness of the top surface of the base 10, the debris can be cleaned by multiple independently sliding sliding bodies 21 and scraper bodies 22, and the cleaning effect is better. At the same time, it can avoid the movement interference between the sliding body 21 and the scraper body 22 and other components, and has the characteristics of stable operation and good avoidance effect.
[0032] Through the elastic connection of the sliding body 21 and the scraping body 22 made of rubber, after the scraping body 22 is continuously scraped and worn, the elastic connection can make up for the gap caused by the wear of the scraping body 22, thereby ensuring that the cleaning effect will not be attenuated due to the wear of the scraping body 22.
[0033] like Figure 7As shown, a slot 30 is provided on the bottom surface of the sliding body 21, and the scraping body 22 is installed in the slot 30. The scraping body 22 forms a rectangular elastic rectangular block structure. The scraping body 22 and the slot 30 are interference fit, and the scraping body 22 is plugged into the slot 30. The scraping body 22 can be installed or removed by inserting the scraping body 22 into the slot 30. After the scraping body 22 is aged and damaged, it is easy to disassemble and replace, and has the characteristic of easy maintenance.
[0034] like Figure 6 and Figure 7 A plurality of deformation slots 31 are provided on the bottom surface of the scraper body 22, and the scraper body 22 forms a comb tooth structure through the deformation slots 31. The deformation slots 31 are rectangular slots, and the deformation slots 31 extend obliquely from the front wall surface of the scraper body 22 to the rear wall surface. The height of the sliding body 21 is less than the thickness of the scraper body 22. The plurality of deformation slots 31 are equidistantly distributed and divide the bottom surface of the scraper body 22 into comb teeth. By providing a plurality of deformation slots 31 at the bottom of the scraper body 22, comb teeth are formed on the bottom surface of the sliding body 21. When the slide 11 linearly displaces, the deformation slots 31 are obliquely provided, so that the scraper body 22 can have a larger deformation amplitude to avoid other components on the basis of ensuring the cleaning and expelling effect of the scraper body 22 on the debris, taking into account the cleaning and prevention of motion interference performance.
[0035] The working principle of the utility model is as follows: insert the scraper 22 into the slot 30 to install or remove the scraper 22, and use the elastic member in the sliding channel 23 to squeeze and push the scraper 22. The elastic member is a spring, and the two ends of the spring are respectively fixedly connected to the top surface of the scraper 22 and the inner top surface of the sliding body 21, thereby ensuring that each sliding body 21 can slide down and approach the top surface of the base 10. For the unevenness of the top surface of the base 10, the debris is cleaned by a plurality of sliding sliding bodies 21 and scraper 22 that slide separately. The elastically connected sliding body 21 and the rubber scraper 22, after the scraper 22 is continuously scraped and worn, the elastic connection method can make up for the gap caused by the wear of the scraper 22, thereby ensuring the cleaning effect. The tilted deformation slot 31 ensures that the scraper 22 has a larger deformation range to avoid other components on the basis of ensuring the cleaning and expelling effect of the scraper 22 on the debris, taking into account the cleaning and preventing motion interference performance.
