Description

Technical Field

[0001] The utility model relates to the technical field of CNC lathes, in particular to a vertical turret device for a double-knife CNC lathe. Background Art

[0002] CNC lathe is one of the most widely used CNC machine tools. It is mainly used for cutting and processing of inner and outer cylindrical surfaces of shaft parts or disc parts, inner and outer conical surfaces of arbitrary cone angles, complex rotary inner and outer curved surfaces, and cylindrical and conical threads, and can perform grooving, drilling, reaming, reaming and boring, etc. Double-tool lathe is a machine tool used for metal processing, with two tool holders, which can perform two different processing operations at the same time. Double-tool lathes are usually used for high-efficiency production and processing, and can perform rough processing and fine processing at the same time to improve processing efficiency and product quality. The lathe turret is an important component of the lathe, which is used to install and replace the turning tool. The turret can rotate so that the turning tool can reach different angles of the workpiece for processing. The double-tool lathe can select different tools and processing methods as needed, which is suitable for the processing needs of a variety of complex workpieces. Rough processing and fine processing can be performed at the same time to improve processing accuracy and product quality. Through the turret, rapid tool change during the turning process can be achieved to improve processing efficiency and accuracy. The rotation of the turret is usually controlled by hydraulic or electric means. The cooling system of the turret is used to cool the cutting area to reduce the temperature of the tool and the workpiece, extend the tool life, and improve the surface quality of the workpiece. The existing turret cooling system is usually installed inside the turret, which is not convenient for adjusting the position of the cooling pipe according to the length of the tool installation, reducing the efficiency and effect of tool cooling. Utility Model Content

The existing turret cooling system is usually installed inside the turret, which is not convenient for adjusting the position of the cooling pipe according to the installation length of the tool, thereby reducing the efficiency and effect of tool cooling.

[0004] To achieve the above objectives, the utility model adopts the following technical solution: a vertical turret device for a double-tool CNC lathe, comprising a turret mounting seat and a turret body, a servo motor is installed inside the turret mounting seat, and a driving spindle is installed at the output end of the servo motor, a sun gear is installed on the driving spindle, and the outer side of the sun gear is meshingly connected with a planetary gear, and the outer side of the planetary gear is meshingly connected with a transmission inner gear ring, a guide ring groove is provided on the outer side of the turret mounting seat, the turret body is installed at the front end of the turret mounting seat, and a lathe tool is circumferentially installed on the outer side of the turret body, a telescopic motor is installed on the outer side of the turret mounting seat, and a telescopic corrugated pipe is connected to the output end of the telescopic motor, and a coolant nozzle is installed on the end of the telescopic corrugated pipe away from the telescopic motor.

[0005] The beneficial effects of the utility model are as follows: during the processing of the workpiece, the telescopic motor pushes the telescopic corrugated pipe to stretch, and the coolant nozzle moves to the outside of the tool. At this time, the coolant cools the tool through the telescopic corrugated pipe and the coolant nozzle. In this way, the position of the coolant nozzle can be accurately adjusted according to different tools, which can effectively ensure the efficiency and effect of tool cooling.

[0006] To reduce friction when planetary gears rotate:

[0007] As a further improvement of the above technical solution: a bearing is installed at the connection between the planetary gear and the turret mounting seat.

[0008] The beneficial effect of this improvement is that the planetary gears are driven to rotate by the sun gear, and the friction force of the planetary gears during rotation can be effectively reduced through the bearings, thereby increasing the service life of the device.

[0009] In order to make the turret body and the transmission inner gear ring rotate synchronously:

[0010] As a further improvement of the above technical solution: the outer side of the transmission inner gear ring is welded to the turret body, and the transmission inner gear ring and the turret body are arranged with their axes coincident.

[0011] The beneficial effects of this improvement are: welding can make the connection between the transmission inner gear ring and the turret body more reliable and firm, and the axis overlap setting can make the rotation of the transmission inner gear ring and the turret body more reliable and stable.

[0012] In order to guide and limit the rotation of the turret body:

[0013] As a further improvement of the above technical solution: a locking sliding installation structure is formed between the turret body and the turret mounting seat through a guide circular ring groove.

[0014] The beneficial effect of this improvement is that when the turret body rotates, the rotation of the turret body can be guided and limited by the guide ring slide groove.

[0015] To increase cooling efficiency and effect:

[0016] As a further improvement of the above technical solution: two telescopic motors are symmetrically arranged about the center line of the turret mounting seat.

[0017] The beneficial effect of this improvement is that the symmetrically arranged telescopic motor can drive the telescopic corrugated pipe and the coolant nozzle to extend and retract, thereby effectively increasing the cooling efficiency and effect of the device, and the tool can be quickly cooled regardless of which side of the tool is used for processing.

[0018] To facilitate the connection between the telescopic corrugated pipe and the telescopic motor:

[0019] As a further improvement of the above technical solution: the telescopic corrugated pipe and the telescopic motor are fixed by a buckle.

[0020] The beneficial effect of this improvement is that the connection between the telescopic corrugated pipe and the telescopic motor can be made more secure through the snap buckle, thereby making it easier for the telescopic motor to drive the telescopic corrugated pipe to extend and for the coolant nozzle to reach the specified position.

[0021] To facilitate tool cooling:

[0022] As a further improvement of the above technical solution: a telescopic mounting structure is formed between the coolant nozzle and the turret mounting seat through a telescopic motor.

[0023] The beneficial effect of this improvement is that the telescopic corrugated pipe can be pushed by the telescopic motor to drive the coolant nozzle to extend and retract. This method can make the extension and retraction of the coolant nozzle more reliable.

[0024] To facilitate the rotation of the turret body:

[0025] As a further improvement of the above technical solution: the turret body and the turret mounting seat are arranged with their axes coincident.

[0026] The beneficial effect of this improvement is that the axis overlap setting can make the rotation of the turret body more reliable and stable, and facilitate the replacement of the tool. BRIEF DESCRIPTION OF THE DRAWINGS
