Problems solved by technology

In a general processing system, the exciting force generated by the regenerative chatter will cause the weak link of the processing system to vibrate. If it is not suppressed, the continuous strengthening of the regenerative chatter will cause the processing quality of the workpiece to deteriorate, or Qualified parts cannot be processed, and it will even cause damage to the processing system

Embodiment Construction

[0032] The technical solutions of the present invention will be described in detail below with reference to the accompanying drawings, but the protection scope of the present invention is not limited to the embodiments.

[0033] Such as figure 1 with 3 As shown, a self-excited vibration drilling tool handle device includes a tool handle body 1 and a tool bar. A mounting hole is provided in the tool handle body 1, and the opening of the mounting hole is located at the right end of the tool handle body 1. On the surface, the mounting hole includes a second threaded hole 19, a blind hole 17, a spline hole 18 and a first threaded hole 14 arranged coaxially from left to right, and the second threaded hole 19, blind hole 17, The diameters of the spline hole 18 and the first threaded hole 14 increase sequentially.

[0034] The knife rod is installed in the mounting hole, and the locking screw cover 13 and the adjusting screw cover 12 are installed in the first threaded hole 14; the...

Abstract

The invention discloses a self-excited vibration drilling cutter handle device, and relates to the technical field of small-diameter deep hole drilling in mechanical manufacturing. The self-excited vibration drilling cutter handle device comprises a cutter handle body, a cutter bar, a piezoelectric ceramic block and a signal conversion and transmission module, a mounting hole is formed in the cutter handle body, an opening of the mounting hole is located in the right end face of the cutter handle body, the cutter bar is mounted in the mounting hole, and the cutter bar can move along the axial direction of the mounting hole; the piezoelectric ceramic block is mounted on the bottom surface of the mounting hole; a spring is arranged between the piezoelectric ceramic block and the left end face of the cutter bar; and the signal conversion and transmission module is installed on the outer side of the cutter handle body and connected with the piezoelectric ceramic block through a signal wire. According to the self-excited vibration drilling device, regenerative vibration in drilling is adjusted into periodic continuous vibration, with a certain rule, of the cutter bar relative to the cutter handle body, so that self-excited vibration drilling is achieved, the drilling efficiency is improved, and the self-excited vibration drilling process can be monitored in real time.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing and drilling small-diameter deep holes, and in particular relates to a self-excited vibration drilling handle device. Background technique [0002] Small-diameter deep hole machining is a technical problem in mechanical processing. Due to the structural characteristics of the drill, chip breaking, chip removal and cutting speed, etc., when drilling small-diameter deep holes with conventional methods, there are low machining accuracy and poor hole wall surface. Poor quality and low processing efficiency. At present, step-feed drilling, low-frequency or ultrasonic vibration drilling, and other special processing methods are generally used for small-diameter deep hole processing, but these methods have problems of low efficiency or high cost. [0003] The universal tool handle device generally includes a tool handle body, a spring collet and a nut. One end of the tool handle body is...
