Description

Technical Field

[0001] This utility model belongs to the field of lathe technology, specifically relating to a vertical lathe. Background Technology

[0002] There are various types of lathes, one of which is the CNC vertical lathe. Its main structure includes a base, column, machine spindle, worktable, crossbeam, tool post, turret, and CNC system. The column supports the crossbeam, the tool post can be raised and lowered on the column, and the tool post and turret can move laterally on the crossbeam. The CNC system controls the machining process, improving machining accuracy and efficiency. The CNC vertical lathe has a stable structure and precise machining control, improving machining accuracy and efficiency, and is suitable for machining workpieces with high precision requirements. The patent application CN222626207U discloses a CNC vertical lathe with a vertical tool post; the structure and principle of the CNC vertical lathe are existing technologies.

[0003] When machining a workpiece on a CNC vertical lathe, the workpiece is mounted on the spindle table using a fixture, and the cutting tool is mounted on the turret. Under the control of the CNC system, the turret moves to achieve machining at different positions on the workpiece. During this machining process, long, ribbon-like chips may remain on the workpiece surface. These chips, wrapped around the workpiece, can scratch its surface. Furthermore, they may also wrap around or impact the cutting tool, causing damage and increasing friction, thus accelerating tool wear. Additionally, the cutting process generates high temperatures, which, if not properly cooled, will affect the performance of both the tool and the workpiece. The current design of CNC vertical lathes lacks features for cooling the cutting area and blowing away chips, which is a deficiency.

[0004] Existing CNC vertical lathes have the problem of not having a design to cool the cutting position and blow away chips when machining workpieces. To address this, this application proposes a vertical lathe. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 5This utility model provides a technical solution: a vertical lathe, including a lathe structure, comprising a spindle rotary platform 12 and a lathe body. During workpiece machining, the workpiece is reinforced and fixed on the spindle rotary platform 12, and the cutting tool is mounted on a tool turret 16. Under the control of a CNC system, the positions of the tool post 15 and the tool turret 16 can be changed to achieve the cutting process of the workpiece. Vertical lathes are existing technology and will not be described in detail in this application; the lifting support includes a fixing block 3 fixed with screws, a lifting cylinder 8, and a vertically connected cross arm 4. The mounting plate 5 of the limiting rod 41, the vertical crossarm 4, and the shield 2 fixed to the crossarm 4 by screws; the fixing block 3 is fixed to the base 11 by screws; when the lifting cylinder 8 is working, the lifting cylinder 8 changes the height of the crossarm 4, the mounting plate 5, and the shield 2; the shield 2 covers the spindle rotating platform 12 and acts as a shield, causing the chips generated by cutting to fall onto the surface of the shield 2; the surface of the shield 2 is conical, which facilitates the cleaning of chips and causes them to fall off; the adjusting assembly includes a linear motor guide rail fixed to the mounting plate 5 by screws. 6. A connecting plate 7, which is fixed to the slider on the linear motor guide rail 6 by screws, and position sensors 71 and cooling nozzles 72 installed at both ends of the connecting plate 7. The cooling nozzles 72 are connected to an external conventional compressed air supply device, such as an air compressor system. The air compressor compresses and stores atmospheric air in an air tank, and then delivers it to the cooling nozzles 72 through pipelines. The cooling nozzles 72 spray high-pressure gas, which can blow away the long strip-shaped chips generated by cutting the workpiece, preventing them from causing wear and damage to the workpiece and the tool. In addition, the high-pressure gas also has a cooling effect, reducing the temperature generated by cutting the workpiece and the tool, and preventing it from affecting the performance of the workpiece and the tool. The application of position sensors 71 is existing technology and will not be described in detail in this application. Position sensors 71 are used to sense the position of the tool. When the tool moves beyond a certain range, the linear motor guide rail 6 runs, causing the connecting plate 7 to move, thereby causing the cooling nozzles 72 and position sensors 71 to move, so that the cooling nozzles 72 and position sensors 71 correspond to the tool, and have an adaptive position adjustment function, which has the functions of blowing away chips and cooling.

[0027] In this embodiment, the lathe body includes a base 11, a column 13, a horizontal shaft 14, a tool post 15, and a tool turret 16. The spindle rotation platform 12 is mounted on the base 11, and the fixing block 3 is fixed to the base 11 by screws. The cutting tool is mounted on the tool turret 16. Under the control of the CNC system, the positions of the tool post 15 and the tool turret 16 can be changed to achieve the cutting process of the workpiece. The structure and principle of the lathe are existing technologies, and this application will not elaborate on them in detail.

[0028] In this embodiment, the limiting rod 41 is inserted into the fixed block 3 and is slidably connected to the fixed block 3. The top of the shield 2 is conical and covers the spindle rotating platform 12 to shield the cutting chips generated by cutting. The surface of the shield 2 is conical, which is conducive to cleaning the chips and making them fall off.

[0029] In this embodiment, the shield 2 has a hollow structure and is equipped with a T-shaped sealing gasket 21 that is plugged in. The sealing gasket 21 is combined with the shield 2 to cover the gap at the center of the top of the shield 2, preventing chips from falling into the interior of the shield 2.

[0030] In this embodiment, a limiting plate 22 is welded to the inner wall of the shield 2, and a ring-shaped bearing 9 is fixed on the top surface of the main shaft rotating platform 12. The bearing 9 includes an inner ring, an internal cage and rolling elements, and an outer ring. Evenly distributed fixing blocks 91 are welded on the outer ring of the bearing 9. The inner ring of the bearing 9 is fixed to the main shaft rotating platform 12 by screws. A limiting groove that cooperates with the limiting plate 22 is opened on the fixing block 91. The limiting plate 22 is limited by the fixing block 91 to prevent the shield 2 and the cross arm 4 from being tilted.

[0031] In this embodiment, the connecting plate 7 includes a "U" shaped plate and rocker plates distributed at both ends. The position sensor 71 and the cooling air nozzle 72 are respectively installed on the corresponding rocker plates, so that the position sensor 71 and the cooling air nozzle 72 are in an inclined state, which facilitates the position sensor 71 to sense the tool and makes it easier for the high-pressure gas ejected from the cooling air nozzle 72 to be sprayed to the contact position between the tool and the workpiece.

[0032] Working principle and usage process of this utility model:

[0033] When the tool is machining a workpiece mounted on the spindle rotary platform 12, the tool cuts the workpiece and chips are generated on the surface of the workpiece.

[0034] The shield 2 covers the spindle rotating platform 12 and serves to shield the cutting chips generated during cutting, causing them to fall onto the surface of the shield 2. The surface of the shield 2 is conical, which facilitates the cleaning of the chips and allows them to fall off.

[0035] The cooling nozzle 72 is connected to an external conventional air compressor supply equipment. When the air is delivered to the cooling nozzle 72, the high-pressure gas ejected from the cooling nozzle 72 blows away the long strip-shaped chips generated during the cutting of the workpiece, thus preventing them from causing wear and damage to the workpiece and the cutting tool.

[0036] In addition, the high-pressure gas ejected from the cooling nozzle 72 also plays a role in cooling, reducing the temperature generated by cutting the workpiece and the tool, and avoiding affecting the performance of the workpiece and the tool.

[0037] The position sensor 71 is used to sense the position of the tool. When the tool moves beyond a certain range, the linear motor guide rail 6 runs, causing the connecting plate 7 to move, which in turn moves the cooling air nozzle 72 and the position sensor 71, making the cooling air nozzle 72 and the position sensor 71 correspond to the tool. It has an adaptive position adjustment function and has the functions of blowing away chips and cooling.

[0038] When the lifting cylinder 8 is started, the horizontal arm 4, the mounting plate 5, and the shield 2 move vertically upward, increasing the distance between the shield 2 and the spindle rotating platform 12, which makes it easier to clean the chips that have entered the shield 2 and does not affect the manual disassembly and assembly of the workpiece on the spindle rotating platform 12.

[0039] In summary: CNC vertical lathes have a design to cool the cutting position and blow away chips. The high-pressure gas ejected by the cooling nozzle 72 blows away the long strip-shaped chips generated during the cutting of the workpiece, preventing them from causing wear and damage to the workpiece and tool. The high-pressure gas ejected by the cooling nozzle 72 also plays a cooling role, reducing the temperature generated during cutting of the workpiece and tool, and avoiding affecting the performance of the workpiece and tool.

[0040] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
