Abstract

A lathe tool belongs to mechanical tools and comprises a tool bit and a tool bar. The tool bit is welded to a tool apron, the tool apron is connected to the upper end of the tool bar through a rotating shaft, and a locking disc is arranged on the rotating shaft. The lathe tool is characterized in that a downward pointer perpendicular to the tool bit is fixed on the tool bit and the tool apron, and an angle scale is adhered to the tool bar and located behind the pointer. When the tool bar is perpendicular to the tool bit, the pointer points to the middle of the angle scale, namely 0-degree, the angle scale is semi-circular and divided into two parts by the 0-degree scale right in the middle, the upper left and the upper right of the scale are respectively 45-degree, and scale intervals are distributed equally in between. When the tool bit is rotated, the pointer points to the scale of the angle scale showing the rotation angle, the locking disc locks the tool bit and the tool bar so that the angle is fixed and unchangeable, and the tool bit and the tool bar form a fixed angle. The lathe tool with an adjusted angle is installed on a lathe, the tool bar is fixed on a tool rest of the lathe, and the lathe is switched on for grinding workpieces. The angle indicated in angle scale is the angle formed by the tool bit and the tool bar, namely the angle of round-hole gradient formed by the workpieces in machining process.

Description

A kind of lathe tool

Technical field

The utility model relates to machine tool, a kind of specifically lathe tool.

Background technology

Lathe tool is the important tool of machine cut processing.The lathe tool that generally uses is made of knife bar and cutter head at present, and cutter head is packed in the front portion of lathe tool, is the part that lathe tool cuts, and the cutting part of cutter head also is the sub-fraction of cutter head.According to the principle of machined into, general lathe tool can only be processed straight hole, can't finish the processing in the hole that has the gradient.

Summary of the invention

In view of the defective that prior art exists, the purpose of this utility model is a kind of lathe tool will be provided, can the acclive circular hole of processing belt.

For achieving the above object, the technical scheme that the utility model adopted is a kind of lathe tool, by cutter head, knife bar constitute, cutter head and tool rest weld together, tool rest is connected the knife bar upper end by rotating shaft, locking plate is arranged in the rotating shaft, it is characterized in that: fixed vertical is in the downward pointer of cutter head on the cutter head tool rest, and knife bar posts angle scale and is positioned at the pointer back, when knife bar is vertical with cutter head, middle 0 degree of pointed angle scale.Angle scale is semicircle, is the boundary with middle 0 degree, and upper left and upper right scale is shown as 45 and spends, between equivalent distribution scale value.Rotary cutter on the scale of pointed angle scale, shows the anglec of rotation, and it is constant that locking plate pins the fixed angle of cutter head and knife bar, and cutter head and knife bar form fixed angle.

After adopting such scheme, compared with prior art have following beneficial effect: the utility model is installed in processing work on the knife rest of lathe, can process the hole that has certain slope, i.e. rounding platform pass, when changing the gradient, the angle of adjusting cutter head and knife bar can satisfy processing request.

Description of drawings

Fig. 1 is a kind of structural representation of lathe tool.

Fig. 2 is a kind of side view of lathe tool.

Among the figure: locking plate 1, angle scale 2, pointer 3, knife bar 4, cutter head 5, rotating shaft 6, tool rest 7.

The specific embodiment

For understanding a kind of structure of lathe tool in depth, be described as follows in conjunction with Fig. 1, Fig. 2:

A kind of lathe tool is made of cutter head 5, knife bar 4, and cutter head 5 and tool rest 7 weld together, and tool rest 7 is connected knife bar 4 upper ends by rotating shaft 6, and locking plate 1 is arranged in the rotating shaft 6.Fixed vertical is in the downward pointer 3 of cutter head 5 on the cutter head tool rest 7, and knife bar 4 posts angle scale 2 and is positioned at pointer 3 back, when knife bar 4 and cutter head 5 are vertical, and middle 0 degree of pointer 3 orientation angle dishes 2.Angle scale 2 is semicircle, is the boundary with middle 0 degree, and upper left and upper right scale is shown as 45 and spends, between equivalent distribution scale value.Before the processing work, rotary cutter 5 on the scale of pointer 3 orientation angle dishes 2, shows the anglec of rotation, and it is constant that locking plate 1 pins the fixed angle of cutter head and knife bar 4, and cutter head 5 and knife bar 4 form fixed angle.To adjust being installed on the lathe of lathe tool of angle, knife bar 4 is fixed on the knife rest of lathe, and start is carried out grinding to workpiece.The angle that shows on the dial, just the angle of cutter head 5 and knife bar 4 formation adds man-hour exactly, and workpiece forms the angle of the circular hole gradient.
