Embodiment Construction
[0014] An impact type vibration damping plunge milling cutter bar, comprising a tool handle 101, a cutter body 102, an outer sheath 1, an inner sheath 2, a steel ball 3, a vibration damping rubber 4, a connecting rod 5, a chute 6, a spring 7, an impact Block 8, Rubber Washer 9, Fixing Bolt 10.
[0015] Wherein, two annular concave arc semicircular grooves are opened on the inner surface of the outer sheath 1, and a threaded through hole is opened directly above the concave arc semicircular groove, and the opening diameter is slightly larger than the concave arc semicircular groove. The diameter is used to assemble the steel ball 3 and the fixing bolt 10; the outer surface of the inner sheath 2 is also provided with an annular concave arc semi-circular groove at the position corresponding to the outer sheath, which forms an annular circular groove with the outer sheath. A number of steel balls 3 are arranged in the annular circular groove, so that the inner and outer sheaths be...

The invention relates to a vibration-absorbing plunge milling cutter bar, in particular to an impact vibration-absorbing plunge milling cutter bar. According to the impact vibration-absorbing plunge milling cutter bar provided by the invention, the vibration problem happened on a large-length-to-diameter ratio plunge milling cutter in the plunge milling processing process can be solved, the wear generated due to the vibration of the cutter is reduced, and the service life of the cutter is prolonged. The impact vibration-absorbing plunge milling cutter bar comprises a cutter handle 101, a cutter body 102, an outer sheath 1, an inner sheath 2, steel balls 3, vibration-absorbing rubber 4, a connecting rod 5, a sliding chute 6, a vibration-absorbing spring 7, an impact block 8, a rubber washer9 and a fixed bolt 10. The cutter handle and the cutter body are connected through screw threads; the steel balls are arranged on the connecting part of the inner sheath and the outer sheath; the fixed bolt is arranged between the inner sheath and the outer sheath, so that the force-bearing steel balls are prevented from being extruded during work; the vibration-absorbing rubber piece is made into a structure with a truncated cone shape, a cylinder and a cone; the rubber piece and the left end of the connecting rod are solidified by adopting a vulcanization technology; and the right end of the connecting rod is connected with the impact block through the spring. The vibration-absorbing plunge milling cutter bar provided by the invention is simple in structure, low in cost, reliable to work, convenient to assemble and maintain, and favorable in vibration-absorbing effect.
Description
technical field [0001] The invention relates to a plunge milling cutter bar, in particular to an impact type vibration damping plunge milling cutter bar. Background technique [0002] In metal cutting, the vibration of the plunger with a large aspect ratio during the cutting process has a direct impact on the cutting force, tool life and surface quality of the workpiece. However, the impact of the tool due to vibration in the cutting process is inevitable, especially in the plunge milling process, in order to meet the large metal material removal rate, the cutting force is large, and the vibration effect is large, which can easily reduce the tool wear. service life. Therefore, it is particularly important to realize the vibration reduction of the plunger shank. [0003] When the system vibrates, the impact damping tool bar uses the impact block to directly impact a part of the vibration system, and uses the impact energy to dissipate the energy of the main vibration system...
