Problems solved by technology

[0002] With the popularization of unmanned chemical factories, the in-line production and processing of CNC lathes has become a trend. However, when CNC lathes process threads, iron filings are not easy to break and are easy to wrap around the workpiece. Chip breaking of iron filings has become a major problem.
Some manufacturers will consider using mechanical chip breaking, but there are many unstable factors in mechanical chip breaking, such as the blade is stuck, the structure is too large to affect the space, etc., so mechanical chip breaking is not the mainstream chip breaking method

Embodiment 1

[0021] As shown in the figure, the CNC lathe high-pressure water outlet turret assembly of the embodiment 1 includes a turret 1, a first tool holder 2, a second tool holder 3 and a water delivery pipe 4. One end of the turret 1 is provided with a turret 11. A tool holder 2 and a second tool holder 3 are mounted on the cutter head 11 , the first cutter holder 2 is fitted with an outer cylindrical cutter 21 , the second cutter holder 3 is fitted with a thread cutter 31 , and the first cutter holder 2 is provided with a threaded cutter 31 . The first water channel 22 and the second water channel (not shown in the figure) are arranged in the second knife base 3, the water outlet of the first water channel 22 is connected with the water inlet of the second water channel through the steel pipe 5, and the water outlet of the second water channel It is connected with the central water outlet (not shown in the figure) of the thread cutter 31. The water inlet of the first water channel 2...

Embodiment 2

[0024]The structure of the high-pressure water outlet turret assembly of the CNC lathe in Embodiment 2 is basically the same as that of the turret assembly in Embodiment 1. The difference is that in Embodiment 2, the water pipe 4 is equipped with a limit position for the movement of the water pipe 4. As for the limiting block 44 , the protective cover 16 is installed on the second support base 13 , and the first proximity switch 17 and the second proximity switch 18 adapted to the limiting block 44 are installed on the protective cover 16 .

[0025] In the above embodiment 1 and embodiment 2, the second tool holder 3 is an outsourced standard thread turning tool holder, specifically a thread turning tool holder with a model number of C6-TRE-BT75A produced by Sandvik Company.

[0026] The high-pressure water outlet turret assembly of the numerical control lathe of the present invention can quickly realize the switching between the thread processing mode and the outer circle proc...

Abstract

The invention discloses a high-pressure water discharging cutter tower assembly of a numerically-controlled lathe. The cutter tower assembly comprises a cutter tower, a first cutter holder, a second cutter holder and a water conveying pipe, wherein an excircle cutter is mounted on the first cutter holder; a threaded cutter is mounted on the second cutter holder; a first channel is formed in the first cutter holder; a second water channel is formed in the second cutter holder; the first water channel is connected with the second water channel through a steel pipe; a water outlet of the second water channel is connected with a central water discharging hole of the threaded cutter; a rapidly replaceable connector socket is mounted at a water inlet of the first water channel; a rapidly replaceable connector plug is mounted at a water outlet of the water conveying pipe; a water inlet of the water conveying pipe is connected with a high-pressure water pump with water discharging pressure of 20-30MPa; a driving mechanism is mounted on the cutter tower; the water conveying pipe is connected with the output end of the driving mechanism. The cutter tower assembly is capable of rapidly switching a threaded machining mode and an excircle machining mode, achieving threaded machining and excircle machining of the workpieces and spraying high-pressure water with pressure being higher than 20MPa from the threaded cutter in the threaded machining process; the problem of chip breaking in the threaded machining process can be effectively solved.

Description

technical field [0001] The invention relates to a numerical control lathe fitting, in particular to a numerical control lathe high-pressure water outlet knife tower assembly. Background technique [0002] With the popularity of unmanned chemical factories, CNC lathes have become a trend for online production and processing. However, when CNC lathes process threads, iron chips are not easy to break, and they are easy to wrap around the workpiece. The breaking of iron chips has become a big problem. Some manufacturers will consider using mechanical chip breaking, but there are many unstable factors in mechanical chip breaking, such as blade jamming, too large structure affecting space, etc., so mechanical chip breaking is not the mainstream chip breaking method. [0003] The current popular chip breaking method is to use high-pressure water to break chips, and the level of water pressure is an important factor that determines the quality of chip breaking. Under the same cutti...
