Abstract
The invention discloses a hydraulic cutter handle, comprising a cutter handle front part, a cutter handle rear part and a jacket. The cutter handle front part and the jacket are connected in a welding mode; the cutter handle front part and a cutter handle tail part are connected in a friction welding mode; oil plugs and steel balls are arranged on the cutter handle front part; the steel balls are connected to the ends of the oil plugs by threads; compression screws, pistons, washers, seal rings and check rings are arranged on the cutter handle rear part. The hydraulic cutter handle is simple and reliable, the clamping capacity and stability are good, the clamping precision is high, and the technical problems of leakage of hydraulic oil and unstable holding force which are easily caused by poor manufacturing tolerance and aging of the seal ring in the use process of the current hydraulic cutter handle are solved.
Description
Technical field
The present invention relates to machinery knives field, be specifically related to a kind of hydraulic pressure handle of a knife.
Technical background
Handle of a knife, is the connector of mechanical main shaft and cutter and other accessory tools, and the current conventional handle of a knife of modern times of traditional handle of a knife mainly contains hydraulic pressure handle of a knife, heat expansion handle of a knife and the types such as type handle of a knife of colding pressing.The method of clamping of hydraulic pressure handle of a knife is different from traditional handle of a knife, only tightening need to be by a pressurization bolt, the sealing block that just can promote piston when bolt tightening produces a hydraulic fluid pressure in handle of a knife, and this pressure passes to steel expansion sleeve from circumferencial direction equably, and expansion wall clamps cutter again.Adopt this tool clamping system, can make system run-out error precision and repetitive positioning accuracy be controlled at below 3 μ m.Owing to having high-voltage oil liquid pressure in handle of a knife, when cutter is clamped, built-in oil recess structure and the existence of hydraulic oil have increased structural damping widely, can effectively prevent the vibration of cutter and machine tool chief axis.
But in the use procedure of hydraulic pressure handle of a knife, to rely on sleeve lining face to realize the clamping to cutter, therefore its clamping force is little, higher to the size of elasticity hole wall and Geometrical Tolerance Principle, and the deformation of the axial both sides of elasticity hole wall and mid portion is inconsistent, during clamping, the various piece of elasticity hole wall, to the adding the power of holding and will have bigger difference of cutter periphery, therefore can exert an influence to the balance of cutter, and then affect the machining accuracy of workpiece.In traditional handicraft, hydraulic pressure handle of a knife is by the version of sealing ring sealing fluid force feed, to complete clamping at chuck place, also can produce because of manufacturing tolerance and the problem such as sealing ring is aging, can cause like this hydraulic oil to be revealed and the unsettled problem of chucking power.
Summary of the invention
To be solved by this invention is that current hydraulic pressure handle of a knife is in use because of manufacturing tolerance with the aging hydraulic oil easily causing of sealing ring is revealed and the technical problem of press force shakiness.
The present invention is achieved by the following technical solutions.Described technical scheme is as follows:
A hydraulic pressure handle of a knife, comprises handle of a knife front portion, handle of a knife rear portion and chuck.Between handle of a knife front portion and chuck for being welded to connect, handle of a knife anterior with handle of a knife afterbody between be connected for friction welding (FW), handle of a knife front portion is provided with oil and blocks up and steel ball, steel ball is threadedly connected to the stifled one end of oil, handle of a knife rear portion is provided with housing screw, piston, packing ring, sealing ring and back-up ring, wherein, housing screw is threadedly connected to one end of piston, the piston other end is aligned in sequence with packing ring, sealing ring and back-up ring, handle of a knife front portion is provided with hole No. one, handle of a knife rear portion is provided with No. two holes and No. three holes, No. one hole is passed through mutually with No. two holes, No. two hole is passed through mutually with No. three holes, a hole, in No. two holes and No. three holes, fill with hydraulic oil.
Preferably, the number of stifled, the steel ball of oil, housing screw, piston, packing ring, sealing ring and back-up ring is respectively 2.
Preferably, the friction welding (FW) coefficient that friction welding (FW) connects is that friction rotating speed is 2200r/min, and fraction time is 20s, and friction pressure is 120MPa, and upsetting force is 240MPa.
Beneficial effect of the present invention is:
The first, the present invention is simple and reliable, adds and holds ability good stability, and clamp precision is high, has solved current hydraulic pressure handle of a knife in use because of manufacturing tolerance and the aging hydraulic oil leakage easily causing of sealing ring and the technical problem of press force shakiness.
The second, the present invention is widely used, and its handle of a knife afterbody can be made into for versions such as BT handle of a knife, HSK handle of a knifes, also goes for all kinds of high accuracy machining tools and uses, and it is applied widely, can come into operation in a large number in machinery knives field.
