Description
Technical field
The utility model relates to metal cutting process technical field, is specifically related to a kind of cutting head with vibration-damping function.
Background technology
In metal cutting process, the cutter of cutting head is generally fixed on the front end of tool holder, and tool holder is installed on the rotating shaft of Work machine with cantilever position.Rotarily driven in the process of Tool in Cutting metal by rotating shaft, tool holder, there is the problem causing machining accuracy to decline because of the tool holder generation vibration of cantilever position, wait to solve.
Utility model content
Technical problem to be solved in the utility model is the deficiency overcoming above-mentioned background technology, and provide a kind of cutting head with vibration-damping function, this cutting head should be able to suppress the vibration in working angles, improves machining accuracy.
For realizing above object, the technical solution of the utility model is as follows:
A kind of cutting head with vibration-damping function, comprise one be shaped with the tool holder of cooling fluid endoporus and be fixed on the cutter head of tool holder front end, it is characterized in that: the front end of described cooling fluid endoporus is shaped with expanded hole, is provided with damper mechanism by jump ring in this expanded hole, described damper mechanism comprises the shock absorber that at least one and cooling fluid female coaxial are installed, the fluid-through tube being arranged on two sealing blocks of shock absorber front-end and back-end, through shock absorber and two sealing blocks respectively; Shock absorber is the cylindrical shape matched with expanded hole, and the axis position of shock absorber is the through hole for installing fluid-through tube, and the barrel of shock absorber offers the one group of retraction slot stretched vertically; Sealing block is shaped with the centre bore for installing fluid-through tube, and the inwall of centre bore is sealed by sealing ring and fluid-through tube, and the outer of sealing block is by the inner wall sealing of sealing ring and expanded hole.
In described one group of retraction slot, wherein the notch of a part of retraction slot is positioned at the front end of shock absorber, the notch of another part retraction slot is positioned at the rear end of shock absorber, and the groove tail of this two parts retraction slot all offers shrinkage hole, and the aperture of shrinkage hole is greater than the width of retraction slot.
Described jump ring is positioned at the front end of damper mechanism, and the outer of jump ring to snap in jump-ring slot that expanded hole inwall offers thus damper mechanism is spacing.
Operation principle of the present utility model is: fluid-through tube passes from the axis of shock absorber, and is sealed at the two ends of shock absorber by sealing block, while guarantee coolant flow, prevent cooling fluid from entering shock absorber;
Vibration can be produced when the cutter head of cutting head is stressed, thus making tool holder also produce vibration, vibration passing is to shock absorber, and shock absorber produces certain elastic deformation by retraction slot and shrinkage hole and absorbs vibratory output, thus reduce the Oscillation Amplitude of tool holder, finally reach the effect of only shaking.
The beneficial effect that the utility model has is: the utility model by arranging damper mechanism in tool holder, absorb vibratory output by the damper elastomeric distortion of damper mechanism, finally reach the effect of only shaking, its structure is simple, use and easy for installation, effectively can improve machining accuracy.
