Description

Technical Field

[0001] This invention belongs to the field of cutting tool technology, and in particular relates to a vibration damping tool. Background Technology

[0002] Turning is a common and widely used machining method in traditional machining. It primarily utilizes the hardness difference between the cutting edge of the tool and the workpiece to achieve the desired shape. Therefore, during the machining process, the tool inevitably vibrates, especially when the cutting edge is not sharp enough.

[0003] Therefore, a cutting tool needs to be designed to alleviate the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a vibration-damping cutting tool to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, one technical solution adopted by the present invention is: a shock-absorbing cutting tool, comprising a cutting tool body and a cutting tool holder, the cutting tool holder comprising a shock-absorbing cylindrical tube, the shock-absorbing cylindrical tube being a single-sided open cylinder, the shock-absorbing cylindrical tube being filled with energy-absorbing filling particles.

[0006] Preferably, the particle size of the energy-absorbing filler particles is less than 1.2 mm.

[0007] Preferably, the weight ratio of the energy-absorbing filling particles to the shock-absorbing cylindrical tube is (1-2):1.

[0008] Preferably, the tool holder is further provided with a hot water suction pipe that allows coolant to be injected, and the energy-absorbing filling particles are located between the shock-absorbing cylindrical tube and the hot water suction pipe.

[0009] Preferably, the shock-absorbing cylindrical tube is further provided with a buffer assembly, which includes a fixing block, an elastic element and a clamping block. The fixing block is fixed inside the shock-absorbing cylindrical tube, and the elastic element is fixed between the fixing block and the clamping block, so that the elastic element applies a force to the clamping block to make the clamping block press against the hot water suction pipe.

[0010] Preferably, the tool holder further includes a mounting head located at the bottom end of the shock-absorbing cylindrical tube and for mounting the tool head, and a pressure plate mounted on the mounting head for pressing against the tool head.

[0011] Preferably, an end cap is detachably connected to the opening of the shock absorber, and the end cap is provided with an elastic clamping element that abuts against the hot water suction pipe.

[0012] The beneficial effects of the present invention are as follows: By setting energy-absorbing filling particles, the present invention can convert the vibration generated by the cutting of the vibration-damping tool into heat energy through the collision and friction of the vibration-damping particles filled in the tool holder, thereby reducing the vibration of the tool holder and improving the machining precision.

[0013] Among them, the hot water suction pipe can absorb the heat generated by the energy-absorbing filling particles, and the buffer component can reduce the vibration of the hot water suction pipe;

[0014] Among them, the elastic clamping component can further prevent damage to the hot water suction pipe. Attached Figure Description
