Description

High pressure center water outlet knife seat

The present invention provides the technical field of a knife holder, especially a high-pressure central water outlet knife holder technically. The pressure of the cooling water can push the water stop valve seat and tightly against the end of the tool, and push the steel ball away, so that the cooling water can only go to the inside of the water stop valve seat and the water outlet hole, and then flow into the tool tip through the water outlet hole in the center of the tool Spraying, so that it can be completely watertight and high-efficiency to cool the tool for processing operations.

By the way, the known central water outlet cutter and its matching conventional cutter holder do not have the design of the water stop valve seat, such as its conventional application No. 101102262 "knife holder structure", there is no movable water stop inside The design of the valve seat, and there are quite a lot of gaps between the tool and the tool holder to cause leakage problems, and the part of the turning tool will also have a side cut plane design for locking, so it is easy to leak, resulting in no water outlet in the center. Water source, or low pressure problem. In addition, please refer to the conventional application No. 104213275 "combined structure of the central water jet casing and the tool holder", in which a cutting plane will be provided on the peripheral surface of the central water jet for locking, but it will also cause considerable damage. large gaps, so will It causes water leakage, so it often causes insufficient pressure of the center water outlet or lack of center water outlet due to leakage, which really needs to be improved.

In view of this, the inventor has been engaged in the manufacture, development and design of related products for many years. After careful design and careful evaluation for the above-mentioned goals, he finally obtained a practical invention.

The main purpose of the present invention is to provide a high-pressure center water outlet knife holder, in which a water stop valve seat is provided in the middle of the tool insertion hole in the knife holder, no matter how the depth of the tool lock is changed, the pressure of the high-pressure cooling water can be used to push the water stop The valve seat tightly supports the end of the tool, and the steel ball can be pushed away, so that the cooling water can only go to the inside of the water stop valve seat and the water outlet hole, and then flow into the tip of the tool through the water outlet hole in the center of the tool and spray out, so that the water can be completely leak-free. Efficiency for cooling tools for machining operations.

In order to achieve the above purpose, the present invention provides a high-pressure central water outlet knife seat, which includes: a knife cover, a water stop valve seat and a cover. There is a tool insertion hole inside the knife cover, and the tool insertion hole runs through the opening at the rear. It can be sealed and fixed by the envelope; the main reason is that there is a long water inlet groove on the side of the knife sleeve, a water guide hole conducts the long water inlet groove and the position behind the tool insertion hole, and the tool insertion hole can be slipped into the sleeve. The water valve seat and the water stop valve seat go through the inner rear side and set a first-order edge to be stuck against one side of a steel ball. The other side of the steel ball is supported by one side of the spring, and the other side of the spring is pressed against the inner surface of the front cover. The front end of the front cover is It is set as a flat nozzle or a tapered head shape with a water outlet, and a leak-proof gasket is arranged around the flat nozzle. According to this, insert the tool into the tool insertion hole and lock it in a fixed position. Because the taper at the end of the water outlet hole in the center of the tool is equivalent to the taper head, when the high-pressure cooling water reaches the tool insertion hole through the long water inlet groove and the water guide hole When the hole is at the back side, immediately push the water stop valve seat against the end of the tool, and use its water pressure to push away the steel ball in the water stop valve seat, so that the cooling water can only go to the inside of the water stop valve seat and the water outlet hole, and then pass through the center of the tool The water outlet hole flows into the tip of the tool and sprays out, so that it can achieve complete water-tight and high-efficiency cooling of the tool for processing operations.

Regarding the technology, means and effects used in the present invention, a preferred embodiment will be described in detail in conjunction with the drawings. It is believed that the above-mentioned purpose, structure and characteristics of the present invention can be gained a deep and specific understanding. .
