Description

Lathe turret component

Technical Field

The invention relates to a lathe, in particular to a lathe turret component.

Background

In machining, multifunctional machining lathes are widely used, in a lathe for machining multiple tools, tools can be arranged in a turret, the tools needed can be rotated to a proper position through rotation, and then a rotating workpiece is contacted with the tools to perform turning.

At present, chinese patent No. CN203579288U discloses a pressurizing device for water guide pillar of cutting water of tool machine tool turret, which comprises a tool machine tool turret and a pressurizing water guide member. The pressurized water guide piece is arranged on the side edge of the tool turret of the machine tool, and the pressurized water guide piece jets out cutting water to cut a product part.

However, the pressurized water guide is fixedly arranged, so that in the rotating process of the cutter head, different cutter mounting positions are required to meet the requirement that a machining opening is aligned with cutting water flow, the adjustment is complex, and meanwhile, pressurized oil is required to be added to ensure the sealing property of the interior, and the structure is complex.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects in the prior art, the invention aims to provide a lathe turret component which is simple in structure, stable in cutting water flow and not easy to leak.

The technical purpose of the invention is realized by the following technical scheme: a lathe turret component comprises a machine shell, wherein a fixed shaft is arranged on the machine shell, an annular cutter disc capable of rotating around the fixed shaft is arranged on the outer sleeve of the fixed shaft, cutter stations which are distributed circumferentially and used for installing cutters are arranged on the cutter disc, a first water guide pipeline in one-to-one correspondence with the cutter stations is further arranged on the cutter disc, one end of the first water guide pipeline is located on the outer wall of the cutter disc, a water outlet nozzle used for spraying cutting water is arranged at a pipe orifice of the first water guide pipeline, the other end of the pipe orifice of the first water guide pipeline is located on the inner wall of the cutter disc and faces the fixed shaft, a second water guide pipeline communicated with external water flow is arranged on the fixed shaft, a butt joint communicated with the first water guide pipeline and the second water guide pipeline is embedded on the fixed shaft, the water flow in the first water guide pipeline impacts the butt joint against the inner wall of the cutter disc, and one side of the butt, the outer cover of butt joint is equipped with the elastic component that is used for driving butt joint and the separation of blade disc inner wall.

Through the technical scheme, the cutter head can rotate around the fixed shaft, different cutters are adjusted to the machining positions, and the workpieces can be machined. And a water outlet nozzle for jetting cutting water flow is arranged beside each cutter station, so that the water outlet nozzles can be independently adjusted according to different cutters on the cutter stations.

Meanwhile, the number of the first water guide pipelines is multiple, and along with the rotation of the cutter head, when a cutter at a certain station processes a product, the butt joint on the second water guide pipeline is aligned with the first water guide pipeline corresponding to the cutter station, and water flow enters the first water guide pipeline through the butt joint and is finally ejected out of the water outlet nozzle at the position for cutting. When water flows, the butt joint is pressed by water flow to enable the butt joint to be tightly attached to the inner wall of the fixed shaft, so that the tightness of the water flow in the conduction process is ensured, and when the water does not flow, the butt joint is driven by the elastic piece to be separated from the inner wall of the cutter head, so that the abrasion of the butt joint in the rotation process of the cutter head is reduced.

All there is independent cutting rivers on every cutter station like this, can independently adjust according to every cutter, and the water route can switch by oneself and let rivers stably switch on when the blade disc rotates suitable position moreover, and it is strong to switch on a leakproofness simultaneously, is difficult for the infiltration, and stability is high, and the pressure of rivers is higher, and the leakproofness is better.

The invention is further configured to: the docking head is made of plastic.

Through above-mentioned technical scheme, the plastics texture is softer, has certain elasticity, can be inseparable with the laminating of blade disc inner wall, and then ensure the leakproofness between butt joint and the blade disc, the butt joint that plastics were made is difficult for damaging the blade disc at the in-process with the blade disc contact simultaneously.

The invention is further configured to: and a boss abutting against the inner wall is integrally arranged on one side of the butt joint in the second water guide pipeline.

The invention is further configured to: the elastic part is a rubber ring, and the rubber ring is located between the boss and the inner wall of the fixed shaft.

Through above-mentioned technical scheme, the structure of boss can increase the area that the butt joint bore rivers pressure, and the drive power that the butt joint received just also is bigger like this, and the butt joint can be more stable with the laminating of blade disc inner wall. In addition, the boss can provide the mounted position of elastic component, can let the stable drive of elastic component to the joint motion.

Rubber has comparatively stable elasticity, can be compressed when it receives pressure, and it can kick-back when pressure reduces, and then stably improves the resilience force, drives the butt joint return.

The invention is further configured to: the outer wall of the butt joint is provided with a waist-shaped positioning hole, and a positioning screw clamped with the positioning hole is arranged on the fixing shaft in a penetrating mode.

Through the technical scheme, the positioning hole is matched with the positioning screw to block the butt joint from rotating in the circumferential direction in the telescopic process, and once the butt joint rotates, the butt joint is easy to butt with the inner wall of the cutter head and is not inosculated. The waist-shaped structure can enable the butt joint to freely slide up and down while being positioned.

The invention is further configured to: and a sealing ring is arranged between the outer wall of the boss and the fixed shaft.

Through above-mentioned technical scheme, the leakproofness between butt joint and the fixed axle can be improved to the sealing washer, and then lets from the inside circulation of butt joint, the seepage can not appear.

The invention is further configured to: fixed axle outer wall cover is equipped with a pair of sealing ring, the blade disc inner wall is provided with the annular and the sealing ring one-to-one with the laminating of sealing ring outer wall, the butt joint is located between the sealing ring.

Through above-mentioned technical scheme, the leakproofness between butt joint and the blade disc can further be strengthened to the structure of sealing ring, even appear the seepage between butt joint and the blade disc, the sealing ring can play last defence line, hinders rivers and spreads in the sword tower.

The invention is further configured to: the cutter head is coaxially provided with a gear disc, the shell is internally provided with a driving motor, and a main shaft of the driving motor is provided with a driving gear meshed with the gear disc.

Through above-mentioned technical scheme, driving motor passes through the rotation of drive gear dish and then can drive the blade disc and rotate, and like this when adjusting the cutter position, driving motor only need drive gear carousel rotate certain angle let the cutter arrive suitable position can.
