Description

Technical Field

[0001] This utility model belongs to the field of machining center technology, and specifically relates to an exhaust device for a machining center gearbox. Background Technology

[0002] A machining center is a highly automated CNC machine tool equipped with a tool magazine and automatic tool changer. It can complete multiple machining processes in a single workpiece clamping operation under computer program control.

[0003] Currently, Chinese utility model patent CN215634865U discloses a gearbox exhaust device. In existing machining centers, the internal movement of the gearbox generates heat during processing, causing gas expansion. If this gas cannot be effectively discharged, it will cause the internal pressure of the gearbox to rise, easily damaging oil seals and other sealing components.

[0004] Common gearbox venting systems typically install vent valves on the vent ports. While this allows for the expulsion of internal gases, external moisture can easily enter the vent ports through the vent valve, potentially causing seal corrosion over time. Furthermore, during gearbox operation, the internal oil generates fumes due to high temperatures. This high temperature causes gas expansion, easily expelling the fumes and oil contaminants from the vent ports. This not only pollutes the machining center's air environment but also causes the oil contaminants to drip into the machining center, affecting workpiece processing. Utility Model Content

[0005] The purpose of this utility model is to provide an exhaust device for a gearbox of a machining center, which has the advantages of preventing moisture from entering the exhaust port of the gearbox and preventing oil fumes and oil stains inside the gearbox from being discharged out through the exhaust port.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an exhaust device for a gearbox of a machining center, comprising an exhaust valve cylinder, an exhaust valve cap provided at the top of the exhaust valve cylinder, and interconnected vent holes and conical grooves respectively opened inside the exhaust valve cylinder, an intermediate column provided inside the conical groove, a welding plate welded to the exhaust valve cylinder welded to the surface of the intermediate column, a telescopic rod bolted inside the intermediate column, a conical plug slidably connected to the intermediate column bolted to the bottom of the telescopic rod, and a first spring welded to the conical plug sleeved on the surface of the telescopic rod.

[0007] Using the above technical solution, the top of the conical groove is covered by an exhaust valve cap. After the vent hole and the conical groove are connected, gas can be discharged outward through the exhaust valve cap. Simultaneously, the exhaust valve cap protects the top of the conical groove, preventing moisture from dripping directly into its interior and improving the protection of the gearbox exhaust port. By fixing the filter cloth to the top of the exhaust valve cylinder, the gearbox gas discharged from the conical groove is filtered, adsorbing and filtering out oil stains from the gas, thus preventing contamination of the machining center's internal environment. Furthermore, the filter cloth is easily removable and can be replaced after oil stains cause blockage, improving practicality.

[0008] The present invention is further configured such that: a threaded rod connected to the intermediate column is welded to the bottom of the exhaust valve cap; a sliding ring is slidably sleeved on the surface of the threaded rod; a second spring connected to the exhaust valve cap is snapped onto the top of the sliding ring; the second spring is sleeved on the surface of the threaded rod; a pressure plate is fixedly sleeved on the surface of the sliding ring; and a filter cloth that works in conjunction with a conical groove is bonded to the inside of the pressure plate.

[0009] By adopting the above technical solution, the gearbox gas discharged from the conical channel is filtered by the filter cloth, and the oil inside the gas is adsorbed and filtered out, thereby preventing pollution of the internal environment of the machining center.

[0010] The present invention is further configured such that a threaded groove is formed on the surface of the exhaust valve cylinder near the vent hole.

[0011] By adopting the above technical solution, the bottom of the exhaust valve cylinder can be fixed inside the exhaust port of the gearbox by being threaded through the threaded groove.

[0012] The present invention is further configured such that: a rubber gasket is fixedly sleeved on the surface of the conical plug and slidably connected to the conical through groove.

[0013] By adopting the above technical solution, the sealing performance of the conical plug between the vent hole and the conical groove is improved, thus preventing gas leakage.

[0014] The present invention is further configured such that a hexagonal bolt groove is formed on the surface of the exhaust valve cap.

[0015] The above technical solution facilitates the rotation of the threaded rod by twisting the exhaust valve cap, thereby making it easy to disassemble and install the filter cloth.

[0016] The present invention is further configured such that: a sealing ring is bonded to the bottom of the pressure plate, the end of the middle column near the conical plug, and the bottom of the exhaust valve cylinder.

[0017] By adopting the above technical solution, the sealing performance is improved, preventing moisture and dust from entering the gearbox exhaust port from other gaps.

[0018] In summary, this utility model has the following beneficial effects:

[0019] 1. By covering the top of the conical groove with an exhaust valve cap, gas can be discharged outwards after the vent hole and the conical groove are connected. At the same time, the exhaust valve cap protects the top of the conical groove, thus preventing moisture from dripping directly into the interior of the conical groove and improving the protection of the gearbox exhaust hole;

[0020] 2. By fixing the filter cloth to the top of the exhaust valve cylinder, the gearbox gas discharged from the conical groove is filtered, adsorbing and filtering out the oil and dirt inside the gas, thereby preventing pollution of the internal environment of the machining center. At the same time, the filter cloth is easy to disassemble and can be replaced after oil and dirt adsorption and blockage, improving practicality. Attached Figure Description

Detailed Implementation

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] Example 1:

[0027] refer to Figure 1 , Figure 2 , Figure 3An exhaust device for a machining center gearbox includes an exhaust valve cylinder 1, an exhaust valve cap 2 at the top of the exhaust valve cylinder 1, and interconnected vent holes 3 and conical grooves 4 inside the exhaust valve cylinder 1. An intermediate column 5 is disposed inside the conical groove 4, and a welding plate 6 welded to the exhaust valve cylinder 1 is welded to the surface of the intermediate column 5. A telescopic rod 7 is bolted inside the intermediate column 5, and a conical stopper 9 slidably connected to the intermediate column 5 is bolted to the bottom of the telescopic rod 7. A first spring 8 welded to the conical stopper 9 is sleeved on the surface of the telescopic rod 7. The exhaust valve cap 2 covers the top of the conical groove 4, allowing gas to escape through the exhaust valve cap 2 after the vent holes 3 and the conical groove 4 are connected. Simultaneously, the exhaust valve cap 2 protects the top of the conical groove 4, preventing moisture from dripping directly into the interior of the conical groove 4 and improving the protection of the gearbox exhaust vents.

[0028] refer to Figure 1 The exhaust valve cylinder 1 has a threaded groove 15 on the surface near the vent hole 3. This allows the bottom of the exhaust valve cylinder 1 to be threaded into the exhaust hole of the gearbox and fixed through the threaded groove 15.

[0029] refer to Figure 2 A rubber gasket 16 is fixedly fitted onto the surface of the conical plug 9 and slidably connected to the conical groove 4. This improves the sealing performance of the conical plug 9 between the vent hole 3 and the conical groove 4, preventing gas leakage.

[0030] Brief description of the usage process: By bolting the exhaust valve cylinder 1 to the exhaust port of the gearbox, the expanding gas inside the gearbox can enter the exhaust valve cylinder 1 through the vent 3. Then, the gas expands and generates pressure, which overcomes the elastic force of the first spring 8 and pushes the conical plug 9 upward, causing the telescopic rod 7 to retract and slide into the interior of the intermediate column 5, thereby connecting the vent 3 and the conical groove 4, allowing the gas to be discharged outward. After the gas is discharged from the gearbox, the internal air pressure decreases, which is insufficient to overcome the elastic force of the first spring 8. The return force of the first spring 8 can then drive the telescopic rod 7 to extend and push the conical plug 9 downward, causing the conical plug 9 to re-seal the conical groove 4 and the vent 3. The exhaust valve cap 2 is then used to cover the top of the conical groove 4, thus providing protection for the top of the conical groove 4.

[0031] Example 2:

[0032] refer to Figure 1 , Figure 2An exhaust device for a machining center gearbox includes an exhaust valve cap 2 with a threaded rod 10 welded to the bottom and threadedly connected to a central column 5. A sliding ring 12 is slidably fitted onto the surface of the threaded rod 10, and a second spring 11, bolted to the exhaust valve cap 2, is snapped onto the top of the sliding ring 12. The second spring 11 is sleeved on the surface of the threaded rod 10. A pressure plate 13 is fixedly fitted onto the surface of the sliding ring 12. The pressure plate 13 has an open interior and a filter cloth 14, which works in conjunction with a conical groove 4, is bonded to it. By fixing the filter cloth 14 to the top of the exhaust valve cylinder 1, the gearbox gas discharged from the conical groove 4 is filtered, and oil stains inside the gas are adsorbed and filtered out, thus preventing pollution of the machining center's internal environment. The filter cloth 14 is also easy to disassemble and can be replaced after oil stains become clogged, improving its practicality.

[0033] refer to Figure 1 The surface of the exhaust valve cap 2 is provided with a hexagonal groove. This allows the exhaust valve cap 2 to be twisted to rotate the threaded rod 10, thereby facilitating the disassembly and installation of the filter cloth 14.

[0034] refer to Figure 2 Sealing rings 17 are bonded to the bottom of the pressure plate 13, the end of the middle column 5 near the conical plug 9, and the bottom of the exhaust valve cylinder 1. This improves the sealing performance and prevents moisture and dust from entering the gearbox exhaust port from other gaps.

[0035] Brief description of the operation: By rotating the exhaust valve cap 2, the threaded rod 10 engages with the intermediate column 5, thus securing the exhaust valve cap 2 to the top of the exhaust valve cylinder 1. Then, as the threaded rod 10 engages with the intermediate column 5, it moves downwards, pushing the sliding ring 12 upwards on the surface of the threaded rod 10. This causes the sliding ring 12 to push the second spring 11 to contract, and the spring's rebound force pushes the sliding ring 12, pressing the pressure plate 13 tightly against the top of the exhaust valve cylinder 1. This allows the gas inside the gearbox to exit through the conical groove 4 and be filtered by the filter cloth 14, removing oil and impurities. Since the exhaust valve cap 2 can be removed from the top of the exhaust valve cylinder 1, only the filter cloth 14 attached to the pressure plate 13 needs to be replaced periodically.

[0036] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
