Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a cutting fluid tank adapted to a vertical machining center with a double spiral chip conveyor. Background Technology

[0002] The cutting fluid tank for the vertical machining center uses a combination of a roller scraper chip conveyor and primary and secondary water tanks. The water tank is equipped with a filtration system and a liquid pump.

[0003] The current water tank is a left-side chip conveyor, which occupies a large width, thus taking up a lot of space in the customer's factory and wasting customer space.

[0004] The current chip conveyor for water tanks is a magnetic chip conveyor. During the vortex processing of aluminum materials, chips of about 100mm are generated, which the magnetic chip conveyor cannot handle.

[0005] Furthermore, the current secondary filtration of the water tank only has a vortex separator (20 microns / 90%). The fine needle-like chips generated by vortex machining can pass through the filter screen of the roller scraper chip conveyor, thus contaminating the primary water tank. They can then escape from the vortex separator into the secondary water tank, affecting the spindle of the machining center and causing the rotary distributor to malfunction and trigger an alarm. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model proposes a cutting fluid tank adapted to a vertical machining center with a double-spiral chip conveyor. By changing the direction of the chip conveyor, this cutting fluid tank can effectively save space in the overall machine tool installation. Furthermore, it is equipped with multiple secondary filtration units, which can effectively improve the cleanliness of the cutting fluid in the secondary tank, extend the service life of the high-pressure pump, and prevent clogging of the tool bore.

[0007] A cutting fluid tank adapted for a vertical machining center with a twin-spiral chip conveyor includes a lifting roller chip conveyor, a chip conveyor guide cover, a primary water tank, a secondary filter unit installed above the primary water tank, and a secondary water tank. The lifting roller chip conveyor and the chip conveyor guide cover are positioned opposite the twin-spiral chip conveyor. The secondary filter unit is located on the connecting pipe between the primary and secondary water tanks. A high-pressure pump for pumping cutting fluid into the machine tool spindle is installed at the top of the secondary water tank. A double-cylinder filter is installed on the connecting pipe between the secondary water tank and the high-pressure pump, and the flow direction of the cutting fluid is controlled by a switching rod.

[0008] As a preferred embodiment of the above technical solution, the secondary filtration unit includes a cutting fluid booster pump, a vortex separator, a vortex filter, and a bag filter connected in sequence.

[0009] As a preferred embodiment of the above technical solution, a flushing pump set is also installed on the primary water tank, which is used to pump cutting fluid into the machining chamber.

[0010] As a preferred embodiment of the above technical solution, a backflush pump is also installed on the primary water tank. The backflush pump is used to pump cutting fluid into the lifting drum chip conveyor to clean the drum filter screen.

[0011] As a preferred embodiment of the above technical solution, a level gauge is also installed on the primary water tank, which is used to detect the depth of the cutting fluid in the primary water tank.

[0012] As a preferred embodiment of the above technical solution, a cutting fluid temperature controller for regulating the cutting fluid temperature is installed on the top of the secondary water tank.

[0013] As a preferred embodiment of the above technical solution, the electrical control box of the cutting fluid tank is installed at the tail of the primary water tank and located near the secondary filtration unit.

[0014] As a preferred embodiment of the above technical solution, both the primary water tank and the secondary water tank are provided with cleaning windows on their tops.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. Saves overall machine tool width space: By changing the left chip discharge setting of the lifting roller chip conveyor to the rear chip discharge setting, the width is consistent with the width of the machine tool, which shortens the overall width space of the machine tool and overcomes the problem of the double spiral chip falling into the rear lifting roller chip conveyor of the machining center.

[0017] 2. Maintainability: Multiple cleaning windows and removable viewing windows are designed to make observation and maintenance operations more convenient, reducing maintenance time and labor intensity.

[0018] 3. Cutting fluid circulation: The design of placing the secondary water tank on the surface of the primary water tank, and the primary water tank adopting a flow channel design, allows the cutting fluid to be filtered out by the roller chip conveyor and pass through a specific flow channel to the machining chamber flushing unit, so that all the cutting fluid is constantly circulating, preventing the cutting fluid from deteriorating and extending its life.

[0019] 4. Advantages of secondary filtration: The cutting fluid from the primary water tank is pumped to the vortex filter (20μm*90%) and the bag filter (20μm) before flowing into the secondary water tank, ensuring the cleanliness of the secondary water tank and greatly extending the life of the high-pressure pump and reducing wear. A dual-cylinder filter (20μm) is added after the high-pressure pump. Normally, one cylinder works while the other is on standby. It also includes a differential pressure alarm. When the working cylinder becomes clogged, the other cylinder can be switched to work directly without affecting the machine shutdown. This further protects the spindle and prevents clogging of the tool bore. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] like Figure 1 , Figure 2 The cutting fluid tank shown is adapted for a vertical machining center with a twin-helix chip conveyor. It includes a lifting roller chip conveyor 1, a chip conveyor guide cover 2, a primary water tank 3, and a secondary filter unit 4 and a secondary water tank 5 installed above the primary water tank 3. The lifting roller chip conveyor 1 and the chip conveyor guide cover 2 are positioned opposite the twin-helix chip conveyor. The secondary filter unit 4 is located on the connecting pipe between the primary water tank 3 and the secondary water tank 5. A high-pressure pump 6 for water outlet at the center of the machine tool spindle is installed at the top of the secondary water tank 5. A double-cylinder filter 7 is installed on the connecting pipe between the machine tool spindle and the high-pressure pump 6, and its switching rod controls the internal flow of cutting fluid and prevents clogging of the tool bore. A one-way valve 8 is used to prevent cutting fluid backflow.

[0025] In this embodiment, the secondary filtration unit 4 includes a cutting fluid booster pump 401, a vortex separator 402, a vortex filter 403, and a bag filter 404 connected in sequence.

[0026] In this embodiment, a flushing pump group 9 is also installed on the primary water tank 3, which is used to pump cutting fluid into the machining chamber.

[0027] In this embodiment, a backwash pump 10 is also installed on the primary water tank 3. The backwash pump 10 is used to pump cutting fluid into the lifting drum chip conveyor 1 to clean the drum filter screen.

[0028] In this embodiment, a level gauge 11 is also installed on the primary water tank 3, which is used to detect the depth of cutting fluid in the primary water tank 3.

[0029] In this embodiment, a cutting fluid temperature controller 12 for regulating the cutting fluid temperature is installed on the top of the secondary water tank 5.

[0030] In this embodiment, the electrical control box 13 of the cutting fluid tank is installed at the tail of the primary water tank 3 and is located near the secondary filter unit 4.

[0031] In this embodiment, both the primary water tank 3 and the secondary water tank 5 are provided with cleaning windows on their tops.

[0032] The working principle of this embodiment is as follows.

[0033] The lifting drum chip conveyor 1, located below the double spiral chip conveyor in the machining center, serves as a primary filter. The inlet of the lifting drum chip conveyor 1 has a chip conveyor guide cover 2, which guides the aluminum chips falling from the left and right spiral chip conveyors to the central lifting drum chip conveyor 1. This lifting drum chip conveyor 1 is equipped with a handle-equipped window cover for cleaning and maintenance. The cutting fluid filtered by the lifting drum chip conveyor 1 flows into the primary water tank 3, which also houses an oil skimmer 14 and other components for processing. The flushing pump unit 9 for the spindle flushing chamber and the electrical control box 13 are also located on the primary water tank 3. The primary water tank 3 uses a cutting fluid lift pump 401 + vortex separator 402 + vortex filter 403 + bag filter as a secondary filtration unit. The cutting fluid after secondary filtration enters the secondary water tank 5. To save floor space, the secondary water tank 5 is placed on the surface of the primary water tank 3. The secondary water tank 5 has a tool center water outlet configuration and a double-cylinder filter 7 to further protect the spindle. It also has provisions for a cutting fluid temperature controller 12. The top of the secondary water tank 5 and the primary water tank 3 are provided with multiple cleaning windows to provide space for maintenance and facilitate observation and maintenance. This design ensures the continuous and efficient operation of the primary water tank 3 and the secondary water tank 5, ensuring the performance and stability of chip handling and cutting fluid circulation.

[0034] Specifically, the electrical signal is provided by the machining center. When the cutting fluid circulation is started, the lifting drum chip conveyor 3 and the cutting fluid lift pump 401 are started. The cutting fluid will circulate and filter the chips in the lifting drum chip conveyor 3, the primary water tank 3, the secondary water tank 5 and the machining center, ensuring that there is no stagnant water in the cutting fluid and that it will not deteriorate.
