Description

Technical Field

[0001] The utility model relates to the technical field of gearbox parts; more specifically, it relates to a ventilation device for a gearbox of a numerical control machine tool. Background Technique

[0002] The main purpose of gearbox ventilation is to maintain internal pressure balance, prevent pressure differences caused by gas expansion or contraction due to temperature changes. At the same time, ventilation can also prevent internal lubricating oil from evaporating due to heat and gas accumulation, thereby avoiding oil pollution and damage to internal components of the gearbox. The ventilation port is usually equipped with a ventilation device, which helps to block dust, moisture and other pollutants from entering the gearbox.

[0003] Currently, during the use of the ventilation device for the gearbox of a numerical control machine tool in the prior art, since the air inlet of some existing equipment is relatively close to the ventilation port on the surface of the gearbox during use, and some existing equipment lacks a structure for blocking the gear oil inside the gearbox, it may cause the gear oil to spray out from the inside of the equipment and form oil stains on the surface of the gearbox, which may block the air inlet of the equipment, thus affecting the ventilation of the gearbox; and some existing equipment is not convenient for filtering impurities in the air. It may cause impurities in the air to enter the inside of the gearbox through the air inlet of the equipment, thus possibly causing pollution to the inside of the gearbox. Therefore, there is an urgent need for a ventilation device for a gearbox of a numerical control machine tool to solve the above problems. Summary of the Utility Model

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides a ventilation device for a gearbox of a numerical control machine tool to solve the problems existing in the above-mentioned background technique.

[0005] The utility model provides the following technical solution: A ventilation device for a gearbox of a numerical control machine tool, comprising:

[0006] A ventilation structure, the ventilation structure includes a ventilation pipe and an upper connecting seat;

[0007] A filtering structure, the filtering structure includes a threaded seat, and the inside of the threaded seat is threadedly connected to the outer surface of the upper end of the upper connecting seat.

[0008] Preferably, the ventilation structure further includes a baffle, and the baffle is fixedly connected to the inner surface of the ventilation pipe, and connecting pipes are fixedly connected to the outer surfaces of the upper and lower ends of the ventilation pipe. The material of the ventilation pipe is rubber, so that the ventilation pipe can be bent during use, and a stainless steel braided layer is provided on the outer surface of the ventilation pipe, which can improve the service life of the ventilation pipe.

[0009] Preferably, a lower connecting seat is internally threadedly connected to one group of the connecting pipes, and an upper connecting seat is internally threadedly connected to the other group of connecting pipes. Sealing gaskets are provided on the outer surfaces at the middle positions of the lower connecting seat and the upper connecting seat. The sealing gaskets are made of rubber, which can improve the sealing performance inside the ventilation pipe.

[0010] Preferably, the filtering structure further includes a filter layer, and the filter layer is placed on the upper surface of the threaded seat. Moreover, the diameter dimension of the filter layer is adapted to the outer diameter dimension of the threaded seat. The filter layer is made of fiberglass, which can filter the air inside it.

[0011] Preferably, a limiting seat is threadedly connected to the outer surface of the upper end of the threaded seat. The inner diameter dimension of the limiting seat is adapted to the diameter dimension of the filter layer, and the upper surface inside the limiting seat fits against the upper surface of the filter layer. By providing the limiting seat, the position of the filter layer can be fixed.

[0012] Preferably, a ventilation plate is fixedly connected to the outer surface of the limiting seat, and a dust-proof cover is fixedly connected to the outer surface of the ventilation plate.

[0013] The technical effects and advantages of the present utility model: Through the setting of one group of connecting pipes, different-sized lower connecting seats can be replaced in the present utility model, thereby improving the applicable range of the device. When the device is in use, the baffle can block the gear oil inside the gearbox, thus avoiding the gear oil from spraying out from the inside of the ventilation pipe to a certain extent. And through the setting of the ventilation pipe, the distance between the ventilation plate and the surface of the gearbox is relatively far, thereby reducing the situation that the oil stains on the surface of the gearbox block the ventilation plate;

[0014] In the present utility model, through the setting of the filter layer, the air passing through its inside can be filtered, thereby preventing impurities in the air from entering the inside of the ventilation pipe through the threaded seat. The position of the filter layer can be fixed by the limiting seat. When the filter layer needs to be replaced, rotate the limiting seat to disengage from the outer surface of the threaded seat, and then the filter layer can be removed for replacement. This design can reduce the pollution of the inside of the gearbox caused by impurities in the air. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Embodiment 1

[0023] As Figures 1 to 3As shown in the figure, the utility model provides a ventilation device for a gearbox of a numerical control machine tool, which includes: a ventilation structure 1. The ventilation structure 1 includes an air pipe 11 and an upper connecting seat 15. The ventilation structure 1 further includes a baffle 12, and the baffle 12 is fixedly connected to the inner surface of the air pipe 11. Connecting pipes 13 are fixedly connected to the outer surfaces of the upper and lower ends of the air pipe 11. A lower connecting seat 14 is threadedly connected inside one group of connecting pipes 13, and an upper connecting seat 15 is threadedly connected inside the other group of connecting pipes 13. Sealing gaskets are provided on the outer surfaces at the middle positions of the lower connecting seat 14 and the upper connecting seat 15. The air pipe 11 is made of rubber, and rubber performs excellently in terms of wear resistance and bend resistance, enabling the air pipe 11 to adapt to various twists and bends and being suitable for complex installation and application environments. A stainless steel braided layer is provided on the outer surface of the air pipe 11. The stainless steel braided layer can effectively improve the compressive and tensile properties of the air pipe 11, making it have high strength and stability under high pressure or high load conditions, reducing the risk of its rupture or deformation. Moreover, the structure formed by the stainless steel braided layer helps to limit the expansion and deformation of the air pipe 11, contributing to improving the sealing performance of the air pipe 11 and reducing the possibility of gas leakage. Additionally, the surface hardness of the stainless steel braided layer improves the wear resistance of the air pipe 11 and can extend the service life of the air pipe 11. Through the setting of the baffle 12, it can play a certain role in blocking the gear oil splashed in the gearbox. At the same time, gas can flow through the gap between the baffle 12 and the inner surface of the air pipe 11. This design can prevent the gear oil from spraying out from the inside of the air pipe 11. The sealing gaskets provided on the outer surfaces at the middle positions of the lower connecting seat 14 and the upper connecting seat 15 are made of rubber. The elasticity and compressibility of the rubber enable it to fit well with the contact surface, thus forming a good seal at the joint to prevent the leakage of gas or liquid.

[0024] Embodiment 2

[0025] As Figures 4 to 5As shown, the present embodiment further proposes: a filter structure 2, the filter structure 2 includes a threaded seat 21, and the interior of the threaded seat 21 is threadedly connected to the outer surface of the upper end of the upper connecting seat 15, the filter structure 2 also includes a filter layer 22, and the filter layer 22 is placed on the surface of the upper end of the threaded seat 21, and the diameter of the filter layer 22 is adapted to the outer diameter of the threaded seat 21, a limited seat 23 is threadedly connected to the outer surface of the upper end of the threaded seat 21, and the inner diameter of the limited seat 23 is adapted to the diameter of the filter layer 22, and the upper surface of the inner part of the limited seat 23 is attached to the upper surface of the filter layer 22, and a ventilation plate 24 is fixedly connected to the outer surface of the limited seat 23, and the ventilation plate 24 is A dust cover 25 is fixedly connected to the outer surface. The filter layer 22 is made of glass fiber. The glass fiber filter can effectively capture tiny particles in the air while maintaining good air circulation, so that the filter layer 22 can provide good filtering performance without significantly hindering the air flow, thereby preventing impurities in the air from circulating through the filter layer 22, and further preventing contamination of the interior of the gear box. The position of the filter layer 22 can be fixed by the setting of the limit seat 23, and the air can circulate through the ventilation plate 24 and the limit seat 23, so as to ventilate the interior of the gear box, and most of the impurities in the air can be blocked by the setting of the dust cover 25.

[0026] Working principle: When the equipment is in use, select a lower connecting seat 14 of appropriate size according to different gear boxes, then thread the upper end of the lower connecting seat 14 with a group of connecting pipes 13, and then connect the upper end of the upper connecting seat 15 with the threaded seat 21. At this time, the gas inside the gear box can be ventilated outward through the air pressure using the ventilation pipe 11 and the ventilation plate 24, and the filter layer 22 can be used to filter the air when taking in air. When the filter layer 22 needs to be replaced, select the limit seat 23 to be separated from the surface of the upper end of the threaded seat 21, and the filter layer 22 can be removed for replacement. Then, the filter layer 22 is placed on the upper surface of the threaded seat 21, and then the limit seat 23 is rotated to fix the position of the filter layer 22, thereby completing the replacement of the filter layer 22. The above is the entire working principle of this utility model.
