Description

Technical Field

[0001] The utility model relates to a mechanical turntable, in particular to a jet-type waterproof machine structure of a mechanical turntable. Background Art

[0002] The mechanical turntable is a commonly used equipment in mechanical precision machining. It mainly includes a turntable, a rotating shaft and a shaft cylinder. The rotating shaft is installed in the shaft cylinder through a bearing and is connected to the turntable to drive the turntable to rotate. Therefore, there is a gap between the turntable and the shaft cylinder. During machining, the coolant can easily penetrate into the shaft cylinder from the gap, causing damage to the bearing. In the past, we set a circular baffle on the edge of the turntable to block the gap through the baffle to prevent the coolant from penetrating into the shaft cylinder from the gap. However, the anti-seepage effect of the above structure is not good enough. The coolant may also penetrate into the shaft cylinder through the gap between the baffle and the shaft cylinder and then through the gap between the turntable and the shaft cylinder. In addition, the baffle increases the weight of the turntable and also increases the power consumption of the motor. Utility Model Content

[0024] Reference Figures 1 to 3 The utility model discloses a mechanical turntable jet waterproof machine structure, including a turntable 1 and a shaft cylinder 2, wherein a gap 3 is provided between the turntable 1 and the shaft cylinder 2. Of course, a rotating shaft 4, a bearing 5 and a fastener are provided in the shaft cylinder 2. The above structure is not an improvement point of the present application, and thus the specific structure is not described in detail. An air inlet 6, a plurality of air outlets 7 and an air duct are provided on the shaft cylinder 2. The air inlet 6 is connected to the air duct, and the air duct is connected to all the air outlets 7. The air outlet 7 is connected to the gap 3. The air inlet 6 is preferably arranged on the side wall of the shaft cylinder 2, so that it is convenient to connect to the air pipe through an air connector and is also convenient for processing. The air duct specifically includes a straight air duct 8 and an annular air duct connected to the straight air duct 8. The air inlet 6 is connected to the straight air duct 8; the air outlet 7 is connected to the annular air duct, and the straight air duct 8 and the annular air duct are both arranged in the wall of the shaft cylinder 2. In order to achieve uniform air pressure, the air outlet holes 7 are evenly distributed in a ring around the central axis of the shaft cylinder 2. The present application has eight air outlet holes 7. Of course, the number of air outlet holes 7 can also be set to ten, six, etc. as needed. In the present application, the shaft cylinder 2 is composed of three sections connected by screws, the air inlet 6 is opened in the middle section, and the straight air duct 8 runs through two of the sections. Of course, the specific structure of the shaft cylinder 2 is an old structure, so the details of the shaft cylinder 2 are not described in detail.

[0025] As shown in the figure, it also includes an annular plate 9, which is fixed to the end of the shaft cylinder 2. The annular plate 9 is provided with an annular groove 10, and the end of the shaft cylinder 2 is provided with an annular groove 2 11. The annular airway is composed of the annular groove 10 and the annular groove 2 11. The air outlet 7 is arranged on the annular plate 9 and is connected with the annular groove 10, and the straight airway 8 is connected with the annular groove 2 11. Through the arrangement of the annular plate 9, we can easily process the annular airway, by processing the annular groove 10 on the annular plate 9, processing the annular groove 2 11 at the end of the shaft cylinder 2, and then fixing the annular plate 9 and the shaft cylinder 2 together by screws, so that the annular groove 10 and the annular groove 2 11 are combined with each other to form an annular airway. As a further structure, the annular groove 10 and the annular groove 2 11 are both square grooves, which are also easy to process. As a further structure, the groove width of the annular groove 2 11 is greater than the groove width of the annular groove 10, so that the compressed gas entering the annular groove 2 11 from the straight air channel 8 is compressed due to the reduction in the groove width when passing through the annular groove 10, so that it can enter the air outlet 7 with a greater pressure and be ejected, so that a high-pressure area is formed in the gap 3, thereby ensuring that when the coolant splashes into the space area, it will be blown out by the high-pressure gas, which has a good waterproof effect and does not increase the weight of the turntable 1.

[0026] The above is a detailed introduction to the structure of a mechanical turntable 1 jet waterproof machine provided in an embodiment of the utility model. Specific examples are used in this article to illustrate the principle and implementation method of the utility model. The description of the above embodiments is only used to help understand the method and core idea of ​​the utility model; at the same time, for general technical personnel in this field, according to the idea of ​​the utility model, there will be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the utility model.
