Abstract
An anti-shake inner thread tool comprises a tool rod (1), a turning tool (2) and a tool pressing bolt (3), and is characterized in that a dovetail groove (4) is formed in the tool rod, and a sliding block (5) is arranged inside the dovetail groove. Due to the technical scheme, the anti-shake inner thread tool is simple in structure and convenient to machine, enables the sliding block to be installed and detached conveniently, avoids the phenomena of shaking and tool receding in the process of machining, and has the advantages of being good in surface accuracy of threads, improving work efficiency and the like.
Description
Technical field:
The utility model relates to a kind of turning cutting tool, particularly a kind of anti-shake internal threading tool.
Background technology:
Trapezoidal thread be widely used and transmission accuracy higher, if the long lead screw on lathe and slide plate leading screw etc. is all to adopt trapezoidal thread transmission, when turning trapezoidal internal thread, because threaded portion is long and aperture is less, knife bar length also lengthens thereupon, because knife bar is longer, in processing, because rigidity is not enough, produce the phenomenons such as shake, cutter relieving, cutting surface roughness is poor and efficiency is low, the serious quality that has influence on product.
Utility model content:
The defects such as the purpose of this utility model is exactly in order to overcome in internal thread machining process, and arbor stiffness is not enough and produce shake, cutter relieving, causes thread surface roughness poor, and machining accuracy is low, and efficiency is low, and a kind of anti-shake internal threading tool providing.
To achieve these goals, the utility model has adopted following technical scheme:
A kind of anti-shake internal threading tool, it comprises: knife bar, lathe tool, push type broach bolt, and lathe tool is contained in the tool bore of knife bar, and push type broach bolt compresses lathe tool, it is characterized in that: on knife bar external diameter, corresponding to one end of tool bore, be provided with the dovetail groove parallel with tool bore, in dovetail groove, be provided with slide block.
Described slide block is circular arc, and the another side corresponding with circular arc is provided with dovetail, and dovetail is parallel with the arc-plane of slide block both sides, and the sliding accessory of dovetail and dovetail groove connects.
Owing to having adopted technique scheme, make the utility model simple in structure, easy to process, slide block adopts sliding accessory to connect, easy installation and removal, and slider support is effective, effectively solve knife bar and produced shake, the phenomenons such as cutter relieving, improve thread surface roughness and precision, and working (machining) efficiency increases substantially.
For more detailed explanation the utility model, following accompanying drawing provides a most preferred embodiment.
Accompanying drawing explanation:
Fig. 1 is schematic diagram of the present utility model;
Fig. 2 is that the A of Fig. 1 is to view.
The specific embodiment:
As shown in Figure 1 and Figure 2, a kind of anti-shake internal threading tool, it comprises: knife bar 1, lathe tool 2, push type broach bolt 3, and lathe tool is contained in 7 li of tool bores on knife bar, and push type broach bolt compresses lathe tool, it is characterized in that: on knife bar external diameter, corresponding to one end of tool bore 7, be provided with the dovetail groove parallel with tool bore 4, in dovetail groove, be provided with slide block 5, slide block is circular arc, and the another side corresponding with circular arc is provided with dovetail 6, dovetail is parallel with the arc-plane of slide block both sides, and the sliding accessory of dovetail and dovetail groove connects.As shown in Figure 2, cutting edge roundness, to the distance on slide block top, equals the radius size of screwed hole, cutter oppositely cuts, and upwards, the top of slide block just in time floats on inner hole wall the cutting force of generation, play a supporting role, in the process of turning, just can not produce like this shake and cutter relieving.
Owing to having adopted technique scheme, make the utility model simple in structure, easy to process, slide block adopts sliding accessory to connect, easy installation and removal, slider support is effective, effectively prevents that knife bar from producing shake, solved and added the cutter relieving phenomenon that produce man-hour, thread surface precision and working (machining) efficiency are increased substantially.
Claims (2)
1. an anti-shake internal threading tool, it comprises: knife bar (1), lathe tool (2), push type broach bolt (3), it is inner that lathe tool is contained in the tool bore (7) of knife bar, push type broach bolt compresses lathe tool, it is characterized in that: on knife bar external diameter, corresponding to one end of tool bore, be provided with the dovetail groove parallel with tool bore (4), in dovetail groove, be provided with slide block (5).
2. a kind of anti-shake internal threading tool according to claim 1, it is characterized in that described slide block (5) is for circular arc, the another side corresponding with circular arc is provided with dovetail (6), and dovetail is parallel with the arc-plane of slide block both sides, and the sliding accessory of dovetail and dovetail groove connects.
