Description

Outer diameter turning tool strong flushing device mechanism

The present invention relates to a cooling device for turning a turning tool, and relates to a cooling device capable of improving cutting efficiency, reducing outer diameter tool wear and better cooling efficiency. This device can be replaced with a tool without disassembly.

In recent years, the material industry has developed rapidly, and the cutting speed is getting faster and faster. The material of the turning tool is getting higher and higher, and the wear of the turning tool is relatively higher. In order to effectively cool this dense heat, the outer diameter car is made. The knife operates under the permissible temperature and usually requires a large amount of cutting fluid and cooling device to assist the cooling of the turning tool and the workpiece to increase the cooling effect and reduce the wear.

The conventional outer water supply device cools the cutting fluid through the cooling water pipe to send the cutting fluid around the outer diameter cutter blade to assist the outer diameter cutter to cool, and the workpiece is at 200 ° C, the surface Naturally, a large amount of water vapor is generated, and the water vapor on the surface of the workpiece blocks the adhesion of the cutting fluid, and the cutting fluid cannot be concentrated on the contact point between the outer diameter cutter blade and the workpiece, so that the cooling effect and the effect of reducing the wear amount of the turning tool are greatly reduced.

The structure improvement and innovation of an outer diameter powerful flushing device, the structure of the powerful flushing device mainly comprises:

Sprinkler:

It is divided into a water spray area and a rotating shaft. The front end of the water spray area has a multi-angle water outlet hole, and the high-pressure cutting fluid is concentratedly injected to the turning tool tip and the workpiece cutting point, and two positioning grooves are arranged at the rear as positioning points.

Positioning steel balls:

The steel ball is placed in the accommodating space between the tool holder body and the rotating shaft of the water sprayer for fixing the upper and lower movement of the water sprayer and serving as a guiding device for the rotation.

Water stop device:

The O-ring is placed in the accommodating space between the tool holder body and the rotating shaft of the sprinkler to prevent leakage of high-pressure cutting fluid;

Stop device:

The flange below the sprinkler is matched with the groove milled by the tool holder body to prevent the sprinkler from exceeding the defined rotation range;

Positioning assembly device:

The positioning assembly is composed of four components: a positioning pin, a positioning cover, a compression spring and a flat head screw.

When the positioning point of the sprinkler rotates above the positioning pin, the positioning pin automatically pops up against the positioning groove of the sprinkler by the upward force of the compression spring to achieve the purpose of positioning and stopping.

Please refer to FIG. 2, FIG. 3, FIG. 4 and FIG. 5 . The present invention provides a cooling device for an outer diameter turning tool, which comprises a tool holder body 1 and a water sprayer 2 . The adapter bolt 4 and the positioning assembly device, the O-ring 7 and the side surface of the rotating shaft on the lower side of the sprinkler 2 and the positioning steel ball 6 are locked in the tool holder body 1 by an M4 hexagonal stop screw 10 The adapter bolt 4 guides the cutting fluid to the sprinkler 2 on the tool holder body 1 (the positioning cover 5 covers the plurality of positioning pins 3 and the plurality of compression springs 8 and is locked by a plurality of flat head screws 11 The devices in the above brackets are collectively referred to as positioning assembly devices.

No need to disassemble and adjust the tool when replacing the blade; rotate the sprinkler clockwise, rotate the groove under the sprinkler and the groove of the tool holder body to the limit position, cooperate with the positioning assembly device, and the positioning pin automatically pops up by the spring Live sprinkler positioning The groove can avoid the interference to achieve the purpose of replacing the blade; after the blade replacement is completed, the water sprayer is rotated back to the limit position, and then the positioning assembly device is used, and the positioning pin is automatically popped up against the nozzle positioning groove by the compression spring. Revert to the original working state.
