Description

Technical Field

[0001] The utility model belongs to the field of precision machining components, and particularly relates to a dividing plate with a gas channel. Background Art

[0002] Generally, the waterproof design of a general CNC dividing plate (CNC rotary table) usually uses an O-ring, sealant or waterproof coating. Although the O-ring is convenient for assembly, it is generally made of silica gel and will age and wear over time, requiring regular inspection and replacement. If the O-ring is not installed properly, it may lead to seal failure and equipment damage. The application of sealant requires precise operation, otherwise it may result in incomplete sealing, and the effect of the sealant will decrease over time, so it must be reapplied regularly, increasing the labor maintenance cost. The waterproof coating may wear or peel off during use and also requires regular inspection and maintenance. In addition, the application of the coating requires professional technology, which not only increases the manufacturing difficulty but also consumes labor costs.

[0003] Therefore, in view of the problems of the above prior art, the utility model further provides a dividing plate with a gas channel to solve the problems generated by the prior art. Summary of the Utility Model

[0004] In view of the above problems, the main object of the utility model is to provide a dividing plate that can quickly drain water and isolate and block the infiltration of water vapor at the same time, improve the waterproof effect, and does not require the replacement of consumables over time, effectively and continuously draining liquids and isolating water vapor.

[0005] To achieve the above object, the utility model provides a dividing plate with a gas channel, including a base, a disk surface and a gas channel. A lower through-hole is provided at the center of the base. The disk surface is detachably arranged above the base. The center of the disk surface has an upper through-hole, and the upper through-hole corresponds to and communicates with the lower through-hole. The gas channel is formed between the base and the disk surface. One side of the gas channel communicates between the upper through-hole and the lower through-hole. The gas channel includes a plurality of cavities and a plurality of drainage channels. The plurality of cavities and the plurality of drainage channels are arranged in an alternating manner and communicate with each other, and the cross-section of the plurality of cavities is larger than the cross-section of the plurality of drainage channels.

[0006] Preferably, a plurality of protruding parts are formed on the surface of the base, and a plurality of groove parts corresponding to the protruding parts are formed on the bottom of the disk surface.

[0007] Preferably, the plurality of drainage channels extend in the vertical direction of the base, and the plurality of cavities extend in the horizontal direction of the base.

[0008] Preferably, the gas channel includes an inner channel, one side of the inner channel is located at the bottom edge of the upper through portion and the top edge of the lower through portion, and the inner channel communicates with the upper through portion and the lower through portion. The other side of the inner channel extends horizontally along the base to one of the plurality of drainage channels.

[0009] Preferably, the indexing plate further includes a liquid storage tank formed on the surface of the base and located at the front end of the gas channel. The liquid storage tank is provided with a drain hole communicating with the external environment for discharging liquid.

[0010] Preferably, the indexing plate further includes a drain pipe disposed in the base. The base is provided with a discharge hole.

[0037] The following will combine the attached drawings in the embodiments of the present utility model Figure 1 ~Attached drawings Figure 4 to elaborate in detail on the technical solutions, structural features, achieved objectives and effects in the embodiments of the present utility model.

[0038] It should be noted that the attached drawings adopt a very simplified form and all use non - precise scales, only for conveniently and clearly assisting in explaining the purpose of the implementation mode of the present utility model, and are not used to limit the limiting conditions for the implementation of the present utility model. Therefore, they do not have technical substantial significance. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the effects that the present utility model can produce and the objectives that can be achieved, should still fall within the scope covered by the technical content disclosed by the present utility model.

[0039] It should be noted that in the present utility model, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non - exclusive inclusion, so that a process, method, article or device including a series of elements not only includes the clearly listed elements, but also includes other elements not clearly listed, or further includes elements inherent to such process, method, article or device.

[0040] Please refer to Figure 1 And Figure 2, the indexing table 1 proposed by the present utility model is a CNC rotary table applied in the field of CNC (Computer Numerical Control), and is mainly a device for rotational positioning in a numerically controlled machine tool. The indexing table 1 can accurately control the rotation angle of the workpiece, realize multi-axis machining, and is used in application scenarios that require high-precision angle control.

[0041] The indexing table 1 includes a base 10, a table surface 20 and a gas passage 30. A lower through portion 12 is provided at the center of the base 10. The table surface 20 is detachably disposed above the base 10. The center of the table surface 20 has an upper through portion 22, and the upper through portion 22 corresponds to and communicates with the lower through portion 12. The gas passage 30 is located between the base 10 and the table surface 20. One side of the gas passage 30 communicates between the upper through portion 22 and the lower through portion 12. The gas passage 30 includes a plurality of drainage channels 34 and a plurality of cavities 36. The plurality of cavities 36 and the plurality of drainage channels 34 are arranged and communicated with each other in an alternating manner, and the cross-sections of the plurality of cavities 36 are larger than the cross-sections of the plurality of drainage channels 34. Therefore, the indexing table 1 proposed by the present utility model uses the gas passage 30 to convey gas, so that a gas waterproof wall is formed in the gas passage 30, thereby preventing liquid or dust outside the indexing table 1 from entering along the gas passage 30, and effectively isolating and blocking the infiltration of liquid or water vapor through the gas passage 30 between the base 10 and the table surface 20, so as to achieve the waterproof effect of the indexing table 1, and since there is no need to replace consumables, the maintenance cost can be reduced.

[0042] The above-mentioned "the plurality of cavities 36 and the plurality of drainage channels 34 are arranged and communicated with each other in an alternating manner" means that the first layer of cavities communicates with the first layer of drainage channels, the first layer of drainage channels then communicates with the second layer of cavities, the second layer of cavities then communicates with the third layer of drainage channels... and so on. Among them, because Figure 2 the shown drainage channels 34 are relatively narrow, and the width shown in the figure is not very obvious, but those skilled in the art should understand that the drainage channels 34 and the cavities 36 communicate with each other and are not in a sealed state, which is used to provide a passage for gas to flow between the drainage channels 34 and the cavities 36. When gas is applied to the gas passage 30, since the cross-section of the cavity 36 is larger than the cross-section of the drainage channel 34, a high-pressure gas will be formed when the gas passes through the slit (i.e., the drainage channel 34). When this high-pressure gas passes through the drainage channel 34, the narrow channel (i.e., the drainage channel 34) will cause the gas flow rate to increase and the pressure to decrease, while the gas flow rate in the cavity 36 will decrease and the pressure will increase. Therefore, through the flow of gas, the gas passage 30 can effectively isolate the entry of liquid and water vapor outside the indexing table 1, thereby effectively improving the waterproof and isolation effects of the indexing table 1.

[0043] Please refer to Figure 2 and Figure 3, a plurality of protrusions 11 are formed on the surface of the base 10, and a plurality of groove portions 21 corresponding to the protrusions 11 are formed on the bottom of the disk surface 20. A space is provided between the protrusion 11 and the groove portion 21 to form a plurality of cavities 36 and a plurality of drainage channels 34. The plurality of drainage channels 34 extend in the vertical direction of the base 10, and the plurality of cavities 36 extend in the horizontal direction of the base 10.

[0044] The indexing plate 1 further includes a liquid storage tank 40 and a drain pipe 50. The liquid storage tank 40 is formed on the surface of the base 10 and is located between the gas channel 30, the upper through portion 22, and the lower through portion 12. The liquid storage tank 40 is provided with a liquid discharge hole 42 communicating with the external environment for discharging liquid. The drain pipe 50 is disposed inside the base 10. The base 10 is provided with a discharge hole 14. One end of the drain pipe 50 communicates with the liquid discharge hole 42, and the other end communicates with the discharge hole 14 for discharging the liquid in the liquid storage tank 40. The horizontal height of the gas channel 30 is higher than that of the liquid storage tank 40 and the drain pipe 50. In this way, the indexing plate 1 proposed by the present utility model can not only effectively prevent liquid from flowing in or water vapor from seeping in, but also effectively discharge the internal liquid, so as to achieve the effect of double waterproofing.

[0045] Figure 3 The arrows shown indicate the direction of gas flow. The number of arrows is only for illustration and does not represent air pressure or flow rate. When the gas supply device applies gas from the inside and injects it between the upper through portion 22 and the lower through portion 12 into the gas channel 30, the gas passes through the first layer of drainage channels 34 and cavities 36. Since the drainage channels 34 are narrow gaps, a swirling flow will be generated in the cavities 36 when the gas is diverted to the cavities 36, thereby generating a gas waterproof wall. When the gas flows through the second layer of drainage channels 34 and cavities 36, since the drainage channels 34 are narrow gaps and the cross-section of the drainage channels 34 is smaller than the cross-section of the cavities 36, a swirling flow will still be generated in the cavities 36 of the second layer, and a corresponding gas waterproof wall will be generated. If the number of the drainage channels 34 and the cavities 36 is more than two layers, the gas diversion path will be the same as the foregoing, and those skilled in the art can analogize the structure of the multi-layer drainage channels 34 and the multi-layer cavities 36 and the gas diversion path through the foregoing. Finally, the gas is discharged to the outside of the base 10 along the gas channel 30. It can be seen that the present utility model has a gas channel 30 with a labyrinth structure, which can effectively isolate liquid and water vapor by gas pressure and prevent liquid from flowing into the internal core structure, so as to obtain a good waterproof effect.

[0046] Please refer to Figure 4 , the gas channel 30 further includes an inner channel 32. One side of the inner channel 32 is located at the bottom edge of the upper through portion 22 and the top edge of the lower through portion 12, and the inner channel 32 communicates the upper through portion 22 and the lower through portion 12. The other side of the inner channel 32 extends in the horizontal direction of the base 10 to the drainage channel 34.

[0047] The gas passage 30 can be connected to the gas supply device 60, which is used to supply gas into the gas passage 30. The position where the gas supply device 60 is arranged is only for illustration and can be adjusted according to actual needs. The gas can be directly or indirectly conveyed to the inner passage 32 through other components, and this is not limited hereby.

[0048] In other embodiments, the present utility model can adjust the size of the cross-section of the gap of each drainage channel 34 according to the design, and ensure that the cross-section of the gap of the drainage channel 34 is smaller than the cross-section of the cavity 36. Preferably, the smaller the gap of the drainage channel 34 is, the better the waterproof effect of the gas waterproof wall is.

[0049] In other embodiments, the base 10 further includes a connecting bearing, which is used to support the rotational movement of the disk surface 20, reduce friction, improve precision and extend the service life. In addition, the base 10 can also provide stable support. Made of high-strength materials, it can also improve the rigidity and stability of the indexing plate 1'. The base 10 can be used to connect the motor and the reduction mechanism to control the rotation angle and speed, increase the torque and reduce the speed, so as to achieve precise control.

After those skilled in the art read the above content, various modifications and substitutions of the present utility model will be obvious. Therefore, the protection scope of the present utility model should be defined by the appended claims.
