It is a set of can indexing control device, whirlwind square milling machine can be made to realize controllable indexing to the other side on part.
As shown in Figure 4,5, 6, a whole set of indexing means is divided into: rotation adjusting sleeve, three spring collet, part fixing tool portions
It is grouped as.It rotates adjusting sleeve and realizes indexing fine tuning, and there is corresponding jackscrew to play angle fixed function adjusted, there is key.Zero
Part fixing tool realizes the position control of multiple clamping, and for the compatibility for improving package unit, spring collet and part are consolidated
Frock making is determined at regular hexagon, to facilitate the indexing requirement of the folk prescription, two sides, tripartite, four directions, six sides of compatible various part.
A kind of whirlwind square milling machine indexing mechanism, including rotation adjusting sleeve 1, spring collet 2 and six side's positioning tools 3.
As shown in Figure 7,8, rotate adjusting sleeve 1 side be evenly equipped with multiple top wire holes I 11 positioned at same circumference, as Fig. 1,
Shown in 2, rotation 1 rear portion of adjusting sleeve is screwed by helicitic texture in 4 end of machine tool chief axis, and top is screwed in its top wire hole I 11
It is positioned after silk I 12, rotation 1 front end face of adjusting sleeve is equipped with locating piece mounting groove 13；Moreover, rotation 1 front end face of adjusting sleeve can be right
Title is set there are two locating piece mounting groove 13.
As shown in Fig. 9,10,11, spring collet 2 includes straight pipe 21 and Taper Pipe section 22, is equipped with and is used in the middle part of spring collet 2
The hexagonal hole 23 of six side's positioning tools 3 is installed, the side of spring collet 2 is circumferentially provided with multiple spring cracks 24, as shown in Fig. 2,
The straight pipe 21 of spring collet 2 is screwed by helicitic texture in 5 end of lathe pull rod, and 22 end face of Taper Pipe section of spring collet 2 is set
There is locating slot 25.
As shown in figure 3, locating piece is fixedly mounted by screw 14 in the locating piece mounting groove 13 of rotation 1 front end face of adjusting sleeve
15, locating piece 15 protrudes into the locating slot 25 of 22 end face of Taper Pipe section of spring collet 2.
As shown in Figure 12,13, workpiece installing hole 31 is equipped in the middle part of six side's positioning tools 3, six side's positioning tools, 3 side is provided with
Two top wire holes II 32, top wire hole II 32 screw in the jackscrew II 33 for fixing workpiece.
The present apparatus is used at the both ends of circular shaft process symmetrical square toes, and specific assembly, will in use, as shown in Figure 1, 2
Circular shaft (workpiece to be processed) is inserted into six side's positioning tools 3, is fixed workpiece by tightening two jackscrews II 33, exposes to be processed one
End；Then by six side's positioning tools 3 insertion spring collet 2 hexagonal hole 23 in, 21 rear end of straight pipe of spring collet 2 screw in
5 end of lathe pull rod, then operates lathe for 5 post-tensioning of lathe pull rod, spring collet 2 is shunk in machine tool chief axis 4, by squeezing
Pressing spring collet 2 keeps its spring crack 24 close and six side's positioning tools 3 is fixedly clamped；Later, 1 rear portion of adjusting sleeve will be rotated
It screws in 4 end of machine tool chief axis, locating piece is installed by screw 14 in the locating piece mounting groove 13 of rotation 1 front end face of adjusting sleeve
15, and locating piece 15 protrudes into the locating slot 25 of 2 front end face of spring collet, realizes the position of machine tool chief axis 4 and spring collet 2
Fixed, screw-in jackscrew I 12 will rotate adjusting sleeve 1 in the top wire hole I 11 of rotation 1 side of adjusting sleeve later and machine tool chief axis 4 is consolidated
It is fixed.After completing assembly, start lathe, with turning feed 7, while machine tool chief axis 4 clamps Work piece high-speed rotation, crouch milling spindle
The also synchronous rotary of cutterhead 6, with the principle of interrupted cut, the square toes in circular shaft one end are completed in the molding of one-time turning multiple edge body
Stop lathe after molding；Then, driving lathe pull rod 5 moves forward, and spring collet 2 is skidded off machine tool chief axis 4 and realizes 2 pine of spring collet
It relaxes, takes out six side's positioning tools 3 at this time, along same position again insertable into spring collet 2 after turning around, then drive lathe pull rod 5
2 retraction lathe 4 of spring collet is realized again and six side's positioning tools 3 is fixedly clamped by post-tensioning, starts lathe later in circular shaft
(workpiece to be processed) other end processes symmetrical square toes.Such as symmetrical square head is processed at the both ends of circular shaft, that is
The corresponding side of both ends square head is generally aligned in the same plane, without angular deviation.Due to increasing rotation in 4 end of machine tool chief axis
This component of adjusting sleeve 1 so that the relative position of machine tool chief axis 4 and spring collet 2 be always it is fixed, in this way take out six sides
After positioning tool 3 turns around, as long as still along same position again insertable into spring collet 2, so that it may guarantee to add at circular shaft both ends
Work go out square toes be it is full symmetric, be not present angular deviation.If there is no rotation this component of adjusting sleeve 1, lathe is driven
After spring collet 2 is removed machine tool chief axis 4 by the Forward of pull rod 5, due to being clearance fit, machine between lathe pull rod 5 and machine tool chief axis 4
Bed pull rod 5 can be rotated at random relative to machine tool chief axis 4, and spring collet 2 is not relative to the position of machine tool chief axis 4 at this time
It is capable of fixing, spring collet 2 is inserted into after six side's positioning tools 3 turn around in this way, driving lathe pull rod 5 is moved back spring collet 2
It tightens when in machine tool chief axis 4, the relative position of machine tool chief axis 4 and spring collet 2 has occurred that variation, in this way in circular shaft two
Hold the square toes that process be it is asymmetric, i.e., both ends square toes, which exist, centainly rotates angle.
If necessary to process the square toes with certain rotation angle at circular shaft both ends, then set in rotation 1 side of adjusting sleeve
There is circular scale (0-360 degree), 0 scale designation is carved on machine tool chief axis 4, after being processed in circular shaft one end after square toes, such as needs
The square toes for rotating angle with 30 degree are processed at circular shaft both ends, rotate 30 degree of angles relative to bed main shaft 4 that will rotate adjusting sleeve 1
Degree, then locks after installing spring collet 2, processes square toes in the other end of circular shaft, then the square toes at circular shaft both ends have at this time
There is 30 degree of rotation angle, realizes the asymmetric square toes controllable angle processing in circular shaft both ends.
A whole set of indexing means concrete function is described as follows:
1, rotate adjusting sleeve: the part is the main control part for realizing sleeve mechanism indexing fine tuning, is adjusted by rotation
Indexing fine tuning is realized in the rotation of set, and now may be implemented in the angle in circumference range by the scale marker in rotation adjusting sleeve is 0.1
The control precision of degree；And there is corresponding jackscrew to play angle fixed function adjusted, have locating piece keep rotation adjusting sleeve with
The rotation of square milling machine main shaft synchronizes.
2, spring collet: in order to make the mechanism to greatest extent on play the compatibility to various angles, control, change it is original
Coil component spring collet shape, using the spring collet of orthohexagonal shape.
3, six side's positioning tool: the tooling and spring collet are all that orthohexagonal shape is realized, by the fixed workpiece of jackscrew；Pass through
Spring collet and part fixing tool realize the position control of multiple clamping.
It should be pointed out that for the those skilled in the art of the art, before not departing from the utility model principle
It puts, several improvement and application can also be made, these are improved and application is also considered as the protection scope of the utility model.
