Description
Technical Field
The utility model relates to a grooving cutter field especially relates to a groove machining cutter with adjustable.
Background
The outer circular groove cutting tool has an integral structure, such as a grooving tool disclosed in ZL 201120238810.2. The maximum processing depth of the excircle slot processing cutter with an integrated structure can be generally very large, but the cutter needs to be integrally replaced after the cutter is worn, damaged and broken. In order to avoid overall replacement of the cutter and save use cost, a plurality of excircle groove machining cutters adopt split type structures, namely the cutters comprise cutter bars and blades, the blades are detachably mounted on the cutter bars, and if the cutting edges are damaged, only the blades need to be replaced. Such as ZL 201710938213.2.
The length of the blade exposed out of the cutter bar of the split type groove processing cutter determines the maximum processing depth of the cutter bar. The longer the cutting edge is exposed out of the cutter bar, the greater the maximum processing depth is, but the torque borne by the cutter bar and the blade is increased during processing; conversely, the shorter the blade is exposed out of the cutter rod, the smaller the maximum processing depth is, but the torque borne by the cutter rod and the blade is reduced during processing.
The length of the existing split type groove machining cutter blade exposed out of the cutter rod can not be adjusted generally, namely the maximum machining depth of the cutter can not be adjusted. The length of the blade exposed out of the cutter bar is the conventional length, so that the blade can adapt to most machining conditions, but can not machine deeper grooves with special designs, and the application range is limited to a certain extent. If the length of the blade exposed to the cutter bar is simply increased, the strength of the cutter bar must be increased or a smaller amount of cutting work must be performed during machining because the torque applied to the cutter bar is increased. Increasing the strength of the blade holder requires increasing the size of the blade holder or improving the material of the blade holder, resulting in an increase in the cost of the blade holder. The use of smaller cutting quantities during machining reduces the machining speed and affects the efficiency.
