Combined with the common five-axis linkage system on the market, it can process parts with complex surfaces and meet the needs of the diversity of fine workpieces.
[0003] The existing five-axis CNC turntable, especially the cradle-type five-axis turntable, uses two rotating feed axes, both of which can be continuously indexed, continuously fed and linked controlled; among them, the feed axis that can rotate arbitrarily is called a rotating axis, and the feed axis that can only rotate forward and backward within a certain angle is called a swing axis.
[0004] This type of cradle-type five-axis turntable usually has the motor installed at the bottom of the cradle. However, when the cradle is rocking, it is inevitable that cutting fluid or other liquids will spill onto the motor, which may easily cause circuit failure or motor damage. Utility Model Content

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of the present invention; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention; the terms "including" and "having" and any variations thereof in the specification and claims of the present invention and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of the present invention or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.
[0028] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0029] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.
[0030] like Figure 1-3 The example shown is an embodiment provided by the utility model.
[0031] The embodiment of the utility model provides a waterproof turntable, including: a base 10, a first driving mechanism 20, a cradle 30, a second driving mechanism 40 and a rotating table 50, the first driving mechanism 20 and the cradle 30 are respectively mounted on the base 10, specifically, the base 10 includes a bottom plate 12, a mounting seat 13 and a tail stock 14, the mounting seat 13 and the tail stock 14 are arranged in parallel at both ends of the bottom plate 12, the first driving mechanism 20 is arranged at one end of the mounting seat 13 away from the tail stock 14, the cradle 30 is rotatably connected between the mounting seat 13 and the tail stock 14, the first driving mechanism 20 is drivingly connected to the cradle 30, and is used to drive the cradle 30 to swing, the second driving mechanism 40 is installed at the bottom of the cradle 30, and the rotating table 50 is installed at the top of the cradle 30, the second driving mechanism 40 is drivingly connected to the rotating table 50, and is used to drive the rotating table 50 to rotate, the rotating axis of the rotating table 50 and the swing axis of the cradle 30 are perpendicular to each other, and the two are located on the same plane. Among them, the bottom of the cradle 30 is sealed and connected with a waterproof shell 31, and the waterproof shell 31 is enclosed outside the second driving mechanism 40, so that when the cradle 30 is flipped and swung, even if the bottom is sprayed with cutting fluid, the second driving mechanism 40 will not be wetted, and the second driving mechanism 40 will not be caused circuit failure or damage, thereby achieving a good waterproof effect.
[0032] Furthermore, the waterproof shell 31 is made of waterproof material, and the outer surface of the waterproof shell 31 is smooth. The size and shape of the upper end of the waterproof shell 31 are adapted to the bottom of the cradle 30, and can completely cover the bottom of the cradle 30, thereby preventing the cutting fluid from leaking into the waterproof shell 31 and achieving a better waterproof effect. In addition, the cross-sectional area of the lower end of the waterproof shell 31 is smaller than the cross-sectional area of the upper end, so that the liquid sprayed onto the surface of the waterproof shell 31 can quickly converge and flow to the lower end, thereby reducing the contact time between the waterproof shell 31 and the liquid.
[0033] Furthermore, a drain port 11 is provided on the bottom wall of the base 10, and the drain port 11 is provided through the middle of the bottom plate 12. The drain port 11 is located directly below the waterproof shell 31, so that the liquid flowing down from the lower end of the waterproof shell 31 can be directly drained from the drain port 11, thereby preventing water from accumulating on the base 10 and affecting the swing of the cradle 30. Moreover, the orthographic projection of the lower end of the waterproof shell 31 on the bottom wall of the base 10 is located within the range of the drain port 11, so that during the swinging process of the cradle 30, the liquid flowing down from the waterproof shell 31 will not fall to other positions on the base 10, thereby ensuring the drainage function of the drain port 11.
[0034] Furthermore, chamfers 311 are respectively provided on both sides of the lower end of the waterproof shell 31 and parallel to the axial direction of the cradle 30, and slopes 111 are respectively provided on the opposite side sides of the drain outlet 11. The slopes 111 correspond to the chamfers 311, so that the liquid sprayed on the waterproof shell 31 can be more concentratedly gathered at the lower end of the waterproof shell 31, and then drip into the drain outlet 11 and drain away. The function of the slope 111 is also to enable the liquid flowing down from the lower end of the waterproof shell 31 to quickly gather in the drain outlet 11 and drain away.
[0035] Specifically, a roller cam reducer 21 is connected between the first driving mechanism 20 and the cradle 30 .
[0036] Obviously, the embodiments described above are only some embodiments of the utility model, rather than all embodiments. The preferred embodiments of the utility model are given in the accompanying drawings, but they do not limit the patent scope of the utility model. The utility model can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the utility model more thorough and comprehensive. Although the utility model is described in detail with reference to the aforementioned embodiments, for those skilled in the art, it is still possible to modify the technical solutions recorded in the aforementioned specific implementation methods, or to replace some of the technical features therein with equivalents. Any equivalent structure made using the contents of the utility model specification and the accompanying drawings, directly or indirectly used in other related technical fields, is also within the scope of patent protection of the utility model.
