TECHNICAL FIELD
[0001] The utility model relates to tool height adjusting technical field, especially a lathe machining adjustable tool center height tool holder. BACKGROUND
[0002] Lathe machining is a common process in mechanical processing, mainly through lathe equipment to workpiece cutting processing. In the lathe machining process, the workpiece is usually fixed on the spindle of the lathe and rotates, and the tool moves along the axial or radial direction of the workpiece, and the excess material is removed by cutting, so that the workpiece is processed into the required shape, size and surface precision. In lathe machining, the adjustable tool center height tool holder is a very important tool, which mainly ensures that the cutting edge of the tool and the rotating center of the workpiece are kept at the same height.
[0003] With the development of traveling wave tubes towards miniaturization and high reliability, traditional lathe machining technology has been difficult to meet the processing requirements of complex and fine parts under high efficiency. In lathe machining, the cutting edge of the lathe tool should be at the same height as the center of the machined part. If the height is not the same, not only the tool will be damaged, but also the center of the machined part will have a convex point, which will affect the size. The traditional method for adjusting the height of the lathe tool is the method of stacking leather pads. The advantage of using the method of stacking leather pads is strong applicability and low cost. However, the thickness of the leather pad has no fixed specification, and the interchangeability is poor. At the same time, a large amount of preparation and adjustment time is required, which greatly affects the work efficiency.
[0004] However, when using shims to adjust the center height of the tool in the prior art, a large amount of preparation and adjustment time is required. Because the thickness of the shims is limited, the operator often needs to determine the required combination of shims by repeated trial fitting and measurement. This process not only consumes time, but also easily leads to insufficient adjustment accuracy due to operation errors. Therefore, a lathe machining adjustable tool center height tool holder is proposed to solve the above problems. UTILITY MODEL CONTENTS
