[0026] Figure 1-Figure 5 The utility model discloses a fully sealed protective structure of a rotary table, which comprises a table 10 , a slide seat 20 , a protective cover 30 , a sealing strip 40 , a locking member 50 and a rotating body 60 .
[0027] In this embodiment:
[0028] The workbench 10 is rotatably mounted on the slide seat 20 , and a groove 11 is provided at the bottom of the workbench 10 .
[0029] The protective cover 30 includes an inner protective plate 31 and an outer protective plate 32. The inner protective plate 31 is installed on the outer periphery of the slide 20 and is fixedly connected to the slide 20. The outer protective plate 32 is arranged outside the inner protective plate 31. The top of the outer protective plate 32 is embedded in the groove 11, and a gap is left between the top of the outer protective plate 32 and the groove 11.
[0030] The sealing strip 40 is installed on the top of the outer protective plate 32 and is located in the gap. The top of the sealing strip 40 abuts against the bottom of the workbench 10, so that a sealing structure is formed between the protective cover 30 and the workbench 10, which effectively blocks the entry of small iron filings. In this embodiment, a circular sealing structure is adopted as a whole, and a solid metal steel plate is made to provide 360° all-round protection. It has good rigidity, simple structure, and compactness, providing a reliable physical barrier, effectively preventing operators or debris from contacting rotating parts, reducing equipment wear, and is easy to disassemble, maintain, and replace. The connection gap of the inner protective plate 31 is staggered with the connection gap of the outer protective plate 32, which effectively blocks liquid infiltration.
[0031] The locking member 50 is used to install the outer protective plate 32 outside the inner protective plate 31, and can adjust the height distance between the sealing strip 40 and the workbench 10 to prevent the sealing strip 40 from interfering with the workbench 10 and affecting the operation of the workbench 10. In this embodiment, there are multiple locking members 50, and the multiple locking members 50 are arranged outside the outer protective plate 32 in a direction parallel to the axial direction of the outer protective plate 32. In other embodiments, multiple locking members 50 are arranged along the outer periphery of the outer protective plate 32, and the adjustment range is wider. The locking member 50 is a screw, a nut, a screw or a bolt.
[0032] The rotating body 60 is located inside the protective cover 30 and is arranged between the workbench 10 and the slide 20 . The rotating body 60 drives the workbench 10 to rotate around its axis to prevent iron filings from entering and affecting the accuracy of the rotating system below the workbench 10 .
[0033] In the present application, a circular sealing structure is adopted as a whole, the inner protective plate 31 is fixed on the slide 20, and the outer protective plate 32 is installed on the inner protective plate 31. The layered installation realizes double-layer protection, which is firm and stable, forming a complete protection area with good protection effect. When the present application is used, the inner protective plate 31 and the outer protective plate 32 are temporarily connected with the locking member 50, and then the sealing strip 40 is inserted into the gap, and then the height distance between the sealing strip 40 and the workbench 10 is adjusted by the locking member 50, and finally the workbench 10 is started to rotate, and the sealing strip 40 and the workbench 10 are checked for interference. If there is interference, fine-tuning is performed, and finally the locking member 50 is locked, so as to realize full sealing protection of the workbench 10. The present application has good full sealing performance, preventing splashes and dust from entering the interior of the protective cover 30; the present application adopts a layered structure, which is convenient for disassembly; the present application has good stability, can resist mechanical vibration and external impact, and provide lasting protection. The present application is suitable for large rotary workbenches 10 over 3 meters, covering and protecting the rotating system under the workbench 10.
[0034] The present application also relates to a machine tool including the above-mentioned fully sealed protective structure of the rotary table.
[0035] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the utility model, several modifications and improvements can be made, which are equivalent modifications and improvements made to the above embodiments based on the essential technology of the utility model, and all of them belong to the protection scope of the utility model.
