The invention discloses a saw-web cooling-water rotating-shaft joint of a multiple-saw-web woodworking machine. The joint is composed of a shaft connection pipe, a water inlet shaft pipe, a seal component, a bearing and the like, wherein the shaft connection pipe and the water inlet shaft pipe are assembled through the bearing, the shaft connection pipe can rotate relative to the fixed water inlet shaft pipe, one end of the shaft connection pipe can be connected with a saw web rotating shaft provided with a central water passing hole, and the other end of the shaft connection pipe is connected with a water delivery hose through the water inlet shaft pipe. Under the sealing function of the seal component, water passes through a water inlet pipe without leakage, wherein the shaft pipe which rotates at a high speed is located at one end of the water inlet pipe, the other end of the water inlet pipe is fixed, and therefore, cooling water is delivered to saw webs needing cooling through the saw web rotating shaft. The saw-web cooling-water rotating-shaft joint solves the technical problems needing resolving when the multiple-saw-web woodworking machine utilizes the saw web rotating shaft to deliver the saw web cooling water, and also can be used for other woodworking machinery, the structural principle of the joint can be extended and applied to mechanisms having the same structure or similar gas-liquid delivery requirements, in particular to connection of pipes having similar delivery requirements, and the joint is a pipe joint having special purposes.

Description

Many saw blades wood-working machine cooling water shaft joint

Technical field

The present invention relates to machinery rotation central siphon and the fixing device that is tightly connected of gas-liquid pipe fitting, particularly a kind of joint that is connected with fixing water pipe for the rotating shaft of many saw blades wood-working machine saw blade.

Background technology

in existing numerous woodworking machinerys, it is that application is more that the many saw blades of log are cut out trigger, result of use is one of woodworker preferably, this wood-working machine is owing to adopting many saw blades to carry out work, the temperature that therefore saw blade of its High Rotation Speed can produce and accumulation is higher than single saw blade, the high temperature of continuous firing can make hardness and the strength decreased of saw blade, add galling, affect the service life of saw blade, and the timber of processing there is harmful effect, to this, the common way of industry is to adopt water-cooled mode to spray water to the saw blade in work, make the saw blade cooling, in the prior art, the spray cooling mode of woodworking machinery is in the appropriate location, working region of cast-cutting saw slice, the water spray tube head to be installed mostly, although this method is installed and is used simple, but exist spray cooling water smoke only can cooling saw blade sawtooth the position, and to the undesirable problem of cooling effect of saw blade middle and lower part, for the more closeer many saw blades wood-working machine of saw blade, the more aobvious protrusion of problem, the sawdust that splashes in working simultaneously also easily stops up water jet, the sawdust that splashes also can intercept water smoke and spray to saw blade, cause cooling bad, in addition water jet is arranged on the saw blade workspace, except objectively also dangerous appropriate, sometimes also can affect the process operation of timber, therefore this way is not the water-cooled best mode of many saw blades woodworking machinery saw blade.

use through reality and show, utilizing the transmission shaft tube that saw blade is installed to spray cooling water to the saw blade in work is one of effective way, the method is to carry cooling water by saw blade spindle central pore to the saw blade of axle head, a plurality of spouts by axle head are sprayed water to every saw blade, each saw blade can be obtained cooling, this mode can be in various degree the problems referred to above of many saw blades of solution wood-working machine, but the technical problem that the method has needs to overcome is: the high speed rotating shaft of saw blade namely requires to be connected hermetically with relatively-stationary external water pipe, accomplish again and can relatively rotate, cooling water can be carried smoothly by joint saw blade spindle central pipe, and water can not be from the joint seepage, therefore solve this technical problem, to realize carrying cooling water to carry out cooling key to saw blade by the saw blade central siphon.

Summary of the invention

The present invention is a kind of many saw blades wood-working machine cooling water shaft joint that proposes for solving the problems of the technologies described above, this connector structure is simpler, manufacture assembling easily, cost is low, reliable, and service life and result of use are preferably arranged, can effectively solve the above-mentioned technical problem that many saw blades wood-working machine will solve.

For solving the problems of the technologies described above, many saw blades wood-working machine cooling water shaft joint provided by the invention comprises axle tube connector, water inlet central siphon, black box, bearing etc., be equipped with bearing and black box in described axle tube connector, the axis hole of bearing is installed described water inlet central siphon, the graphite friction member of axle tube connector and genus black box can rotate with respect to other part of water inlet central siphon and black box, and wherein the potsherd of black box and graphite friction member interface form the dynamic friction sealing.

With the female thread structure that is connected with the saw blade central siphon, other end endoporus is useful on the mating surface of running in bearings at axle tube connector one end, is useful on also in the axle tube connector that installation shaft is held and the structure of graphite friction member; There is axial water flowing pore at described water inlet central siphon center, the axostylus axostyle disc has the bearing assemble face that coordinates with brearing bore, water inlet central siphon one end connects delivery hose, the other end is for installing the spill disk of black box, above-mentioned bearing is loaded onto into the water central siphon, again bearing top circle is packed into bearing assemble face in axle tube connector endoporus can make and realize that the axle tube connector is with respect to the rotation of water inlet central siphon, black box.

Many saw blades wood-working machine rotating shaft water pipe joint of the present invention, its beneficial effect is not only to can be used for corresponding woodworking machinery, its structural principle is also extensible to be applied to other and to have similar structures requirement or similar liquid gas to carry the frame for movement that requires, some food and drink particularly, therefore the gas-liquid pipelines of specific (special) requirements etc. are a kind of Petrochemical Pipe Joints that special purposes is arranged.
