Description
Technical field
The present invention relates to the metal cutting technology field, relate in particular to the cutter holder of clamping indexable insert tip, throw away tip.
Background technology
In the metal turning process, often run into need to be on workpiece the narrow groove of turning or the situation of cutting workpiece, the metal cutting tool that is used for this type of work adopts comparatively expensive hard material to make usually.In order to save cost, this cutter is made blade and two parts of cutter holder, and blade is made of hard material, has cutting edge and certain installation and positioning structure, and the chucking power that can rely on the external force such as screw in compression to provide installs, fixing.After the cutting edge wearing and tearing, blade can be taken out from cutter holder, and change another blade and proceed cutting.Because it is smaller that blade mostly is width, the structure that length-width ratio is larger is being installed, is being difficult to fully compress at length direction fixedly the time, thus when compressing the larger potential safety hazard of existence.In machining, guarantee from start to finish stable being fixed on the cutter holder of blade, the problems such as blade comes off, play do not appear, and be the reliability that guarantees the product to be processed processing dimension, and the key factor of the security of product.
Cutter holder of the prior art as shown in Figure 6 and Figure 7, the chucking face of the upper gripping part of its cell body 2 is a continuous surface, when blade 3 is placed on cell body 2 when interior, blade 3 is a kind of matched in clearance with cell body 2, rely on external force that housing screw 4 provides so that upper card-tight part rotates relative to neck is flexible, the front end elder generation contactor blade 3 of the chucking face of upper gripping part is along with housing screw 4 externally applied forces increase, bring out now a certain amount of distortion in face of the chucking of upper gripping part, and reach very soon deformation limit.And, the contact length of the chucking face of gripping part and cell body 2 is very little on the blade 3, upper positioning groove length with respect to blade 3, the first half section that does not also surpass locating slot, even not above 1/3 length, that is to say the second half section of the upper locating slot of blade 3, even be contacted with any chucking face of tool holder body 1 on 2/3 the rear end length, is far from being enough in the length that tightens.In process, because blade 3 is subjected to the effect of axial force, blade 3 is easy to that contacted that is a bit of as pivot take the upper locating slot of blade 3 and cutter holder chucking face, and play occurs, thereby cause the uncontrollable of work piece size, even cause scrapping of the broken and product of collapsing of blade 3 etc.
Summary of the invention
The technical problem to be solved in the present invention is to overcome the deficiencies in the prior art, provides a kind of chucking power to strengthen, can improve the reinforced cutter holder that is used for the clamping indexable blade of processing safety and stability.
For solving the problems of the technologies described above, the present invention by the following technical solutions:
A kind of reinforced cutter holder for the clamping indexable blade, comprise tool holder body, described tool holder body is divided into neck, upper card-tight part and lower support section, described neck, upper card-tight part and lower support section surround a cell body, described cell body is divided into the blade gripping section and extends to the extension of neck, described upper card-tight part comprises front card-tight part and rear card-tight part, and described rear card-tight part is provided with elastic groove.
Described front card-tight part has front chucking face, and described rear card-tight part has rear chucking face, has height difference H between described front chucking face and the rear chucking face, and 0＜H≤1mm.
Described front card-tight part has front chucking face, and described rear card-tight part has rear chucking face, has angular difference between described front chucking face and the rear chucking face, and 0 °＜α＜90 °.
Described elastic groove is positioned at rear card-tight part top, and the opening of elastic groove is towards the extension of cell body.
Compared with prior art, the invention has the advantages that: the upper card-tight part of cutter holder comprises front card-tight part and rear card-tight part, and be provided with elastic groove at rear card-tight part, this elastic groove makes rear card-tight part have independently elasticity and deformation space, strain by rear card-tight part improves the compression intensity of cutter holder blade, make the location of blade reliable, dismounting is quick; Simultaneously, the opening of elastic groove is towards the extension of cell body, therefore can not reduce because of the opening of elastic groove the contact area of the upper clamping slot of upper card-tight part and blade, make the clamping force distribution more even, thereby avoid blade to rupture or split because of irregular appearance that be stressed.When adopting cutter holder clamping blade of the present invention, front card-tight part and rear card-tight part compress simultaneously blade on end tight groove, increased the contact area of clamping slot on cutter holder and the blade, make card-tight part be applied to that the thrust of clamping slot is more evenly distributed on the blade, prevent that blade from rotating around the contact point of cutter holder and blade, clamping stability and processing safety all are improved.Be provided with rational difference in height or differential seat angle between front chucking face and the rear chucking face, thrust between front chucking face and rear chucking face and the blade has obtained rational distribution, the rear and front end of the upper and lower clamping slot of blade is all contacted with corresponding chucking face on the cutter holder, reach desirable clamping effect, make from start to finish stable being fixed on the cutter holder of blade.Reinforced holder structure for the clamping indexable blade of the present invention is simple, and production cost is low, and performance significantly promotes.
