Milling attachment structure and working principle of the present invention：
The milling attachment as shown in Fig. 2 by crossbeam 1, milling head 2, alignment pin 3, alignment pin 6, clamping device 4, rotation dish 5 with
And the grade of gripping block 7 composition.Its structure is as follows：
As shown in Figure 3, Figure 4, a kind of circular table T-slot milling attachment, including milling head 2, crossbeam 1, gripping block 7, turn
Moving plate 5, alignment pin 3 and alignment pin 6, described rotation dish 5 are arranged on the center of workpiece, and the bottom of rotation dish 5 is the face of cylinder, can be with
Inner hole of workpiece is engaged；Described gripping block 7 is placed on diverse location along workpiece circumferencial direction, is fixed with workpiece after determining position
Together；One end of described crossbeam 1 is arranged in described rotation dish, and the other end is arranged in described gripping block 7, described
Milling head 2 be arranged on described crossbeam, can in the horizontal direction move back and forth along the crossbeam, and the milling head is self-powered
Milling cutter is driven to rotate；Milling head also can vertically move up and down simultaneously, to adjust milling cutter position.
The present invention uses " plodding away at a big job bit by bit " method milling T-slot.Workpiece is not required to clamp, and milling attachment is directly anchored to work
On part.
Further, three groups of alignment pins are installed in rotation dish 5, are respectively (straight pin 3-1, chamfered edge pin 3-2；Straight pin
6-1, chamfered edge pin 6-2；Straight pin 8-1, chamfered edge pin 8-2) described in crossbeam be arranged on three different positions by three groups of alignment pins
Put, there is and coordinate the rotation of rotation dish, realize on workpiece positioned at diverse location T-slot processing.
In accompanying drawing 3, crossbeam has been arranged on straight pin 8-1, chamfered edge pin 8-2, and the bottom of crossbeam 1 is provided with two location holes,
Two location holes coordinate with straight pin and chamfered edge pin respectively, realize the fixation of crossbeam.
Further, each group of alignment pin is installed on the same line, three straight lines that three groups of described alignment pins are formed
It is parallel to each other；Crossbeam 1 and three groups of detent fits of diverse location, can complete 3 kinds of different T-slots of relative home position
Processing.
Further, wherein two groups of alignment pins are positioned at the same side of rotation dish center line, another set alignment pin is located at and turns
The opposite side of Moving plate center line, the structure are primarily to meeting the different distance between the T-slot that is parallel to each other on workpiece and setting
Meter；Certainly in concrete application, the different of T-slot diverse location can be required to be designed according to different workpieces.
Rotation dish 5 is fixed in inner hole of workpiece by clamping device 4, unclamps clamping device 4, can be with rotary motion disk 5.Folder
Tight device 4 includes clamping press plate, turnbuckle etc., and its Main Function is to be clamped rotation dish 5.
Specific positioning principle and processing method are as follows：

Milling head 2 can be moved along the guide rail of crossbeam 1, and servomotor and reducing gear drive milling head to realize feed motion；Milling
Self-powered driving milling cutter is rotated；Milling head also can vertically move up and down, to adjust milling cutter position.
2. positioning principle
The bottom of rotation dish 5 is the face of cylinder, can be engaged with inner hole of workpiece, and there are 3 groups of alignment pins (see Fig. 3), crossbeam in upper surface
There are 2 setting circle post holes on interior survey bottom surface, should be by 1 group of alignment pin 2 location hole of insertion when crossbeam is positioned.Using alignment pin 3
And during close 1 group of alignment pin, for processing 2 parallel T-slots；And rotation dish is turned over into certain angle, then by crossbeam
When bottom surface location hole coordinates with alignment pin 6, it is ensured that the processing T-slot plane of symmetry passes through the center of circle.
3. manufacturing procedure process
1) workpiece is directly placed on ground or is placed on cushion block, keep suitable height, because workpiece is heavier, no
Need to clamp.
2) rotation dish 5 is placed in the endoporus that workpiece turning is finished, alignment pin 3,6 has been installed in rotation dish 5
And clamping device 4, clamping device 4 has clamping press plate, turnbuckle etc. below, after locking, is conducive to improving system stiffness, reduces
Vibrated during machining.
3) crossbeam 1 and the component of milling head 2 are sling, interior survey is placed in rotation dish 5, and coordinates with alignment pin 3 or 6, separately
One end is placed in gripping block 7 and tightens each attachment screw.Locating piece 7 can be placed on diverse location along workpiece circumference, it is determined that
Can be also fixed together with workpiece behind position.
4) add man-hour requirement to lock gripping block 7 and clamping device 4, milling head 2 is transferred to correct position, first process near the center of circle
Withdrawing hole, then change slotting cutter and T-slot cutter and process T grooves side and working face respectively.
5) after completing 1 T-slot of processing, unclamp the lock-screw of clamping device 4 and gripping block 7, make crossbeam 1, milling head 2 and
The grade of gripping block 7 together around rotation dish 5 turn to correct position after (need special angle detection instrument or line), locking 4 and 7
Afterwards, second processing of T-slot can be carried out, until completing the processing of all T-slots on relevant position.
6) crossbeam 1 and the component of milling head 2 and another group of detent fit are lifted, above step is repeated, in processing other positions
T-slot.
Further, when rotation dish is maintained static, the position of crossbeam is only adjusted, makes its detent fit from different groups
When, it is possible to achieve the processing of the T-slot being parallel to each other.
Further, when crossbeam is with a certain group of detent fit, then rotary motion disk, it is possible to achieve along same
The processing of the T-slot of circle different radii directional spreding.
Further, by adjusting the spacing between different groups of alignment pin, it is possible to achieve between the T-slot being parallel to each other
Distance adjustment.
As can be seen from the above description, the application the above embodiments realize following technique effect：
3) " plodding away at a big job bit by bit " method milling T-slot is used.Workpiece is not required to clamp, and milling attachment is directly anchored to workpiece
On.
4) crossbeam and the detent fit of diverse location, can complete adding for 3 kinds of different T-slots of relative home position
Work.
3) crossbeam, milling head etc. can be rotated around the workpiece center of circle, realize indexing, process a plurality of T symmetrical in a circumferential direction
Type groove.
4) present invention need not use large scale equipment, milling attachment small volume, lightweight, reduction processing charges.Accompanying drawing is said
It is bright
Although above-mentioned be described with reference to accompanying drawing to specific embodiment of the invention, not to present invention protection model
The limitation enclosed, one of ordinary skill in the art should be understood that on the basis of technical scheme those skilled in the art are not
Need the various modifications made by paying creative work or deformation still within protection scope of the present invention.
