Abstract
The invention relates to a cutting mechanism, in particular to a stair-type gyroscope anti-vibration boring rod. The stair-type gyroscope anti-vibration boring rod comprises a boring rod portion and a gyroscope portion. The diameter of the front portion of the boring rod changes according to the stair shape. A cutter containing square hole is formed in the top end of the front portion of the boring rod. A fastening screw matched with the square hole is arranged inside the square hole. The stair-type gyroscope anti-vibration boring rod is simple in structure, easy to manufacture and good in damping effect, the machining efficiency is high when a deep hole is bored, and the machining precision of the hole can be effectively ensured.
Description
Technical field
The present invention relates to a kind of cutting mechanism.
Background technology
For size and the accuracy of form and position, have relatively high expectations, bore dia is larger, surface roughness is had relatively high expectations, hole depth is darker, and the hole class workpiece that is not suitable for processing on lathe, because the length that overhangs of knife bar when the bore hole is longer, rigidity, intensity are poor, in Boring Process, be easy to produce cutting vibration, both affected the crudy in hole and the service life of cutter, simultaneously owing to can not adopting high-speed cutting also will affect production efficiency.And special-purpose damping vibration resistant cutter bar is because price is higher, medium-sized and small enterprises are difficult to bear mostly.。
Summary of the invention
The present invention aims to provide the ladder type top anti-vibration boring bar that a kind of processing cost is lower.
Ladder type top anti-vibration boring bar of the present invention, comprises boring bar part and gyro part, and wherein the diameter of boring bar front portion is pressed stairstepping variation, and this anterior top is provided with dress cutter square hole, is provided with the trip bolt matching in square hole.
Preferably, described boring bar rear portion is provided with No. 6 taper shanks of Mohs.
Or preferably, gyro partly comprises fixedly gyro cover and interchangeable gyro, and wherein fixedly gyro cover front end is enclosed within on the cylindrical of boring bar rear portion regularly.
More preferably, fixedly gyro cover is that interference is connected with boring bar rear portion cylindrical.
Further preferably, fixedly gyro cover is with the diameter of boring bar junction than the large 0.5-1mm of corresponding position boring bar diameter, and this place is provided with three screws, and screw is provided with the firm screw of edge copperhead.
The present invention is simple in structure, makes easily, and good damping result, during boring deep hole processed, working (machining) efficiency is high, can effectively guarantee the machining accuracy in hole.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure, 1. trip bolt 2. ladder boring bars 3. fixedly gyro overlap 4. interchangeable gyro 5. trip bolts 6. edge copperhead trip bolts.
The specific embodiment
Embodiment mono-
As shown in Figure 1, ladder type top anti-vibration boring bar of the present invention is mainly by trip bolt 1, ladder boring bar 2, fixedly gyro cover 3, interchangeable gyro 4, trip bolt 5 and edge copperhead trip bolt 6 form.According to function, be mainly divided into boring bar part and gyro part.
The anterior diameter of boring bar changes according to stairstepping, and according to power transmission principle, the straight line that each step of ladder boring bar can be alleviated vibration force transmits continuously, thereby reduces the partial vibration that resistance to cutting causes.Boring bar rear portion adopts No. 6 taper shanks of Mohs, and highly versatile and easily making are higher with tapered bore of machine tool spindle quality of fit.There is dress cutter square hole on the top of boring bar front portion, and for mounting cutter, cutter adopts housing screw 1 to be fastened on boring bar.
Gyro part is by fixedly gyro cover and interchangeable gyro form.Fixedly gyro cover front end is arranged on the root cylindrical of ladder boring bar, adopts interference fit to connect between the two, and fixedly gyro cover is fastened on multidiameter.Fixedly the large 0.5-1mm of gyro cover rear end aperture ratio boring spindle outside dimension, is evenly equipped with 3 M14 screws at its cylindrical position.When boring bar taper shank coordinates with boring spindle taper hole after clamping, 3 edge copperhead trip bolts are evenly fastened on boring spindle front end cylindrical, can effectively increase the rigidity that boring bar is connected with main shaft, thereby eliminate boring bar and be arranged on the rigidity weak link on machine tool chief axis, improve the ability of boring bar resistance to deformation.
