According to one side of the present utility model, offered on the fixing body be engaged when being rotated with fixing body it is anti-
Shake hole.
The advantages of the utility model is implemented：There is corresponding positioning hole on each positioning disk, and it is two neighboring fixed
The angle of line is equal to the angle that workpiece needs to rotate between position hole and positioning disk center, adds again so after to workpiece corner
When work, alignment pin only need to be penetrated to adjacent positioning hole, so just can be directly and precisely to the position of positioning disk
Put and be adjusted and fixed, without angular adjustment error etc., the workpiece of different angle requirement is processed when
Wait, can be also adjusted by changing different positioning disks, so as to ensure that the accuracy of processing, crudy height.
Brief description of the drawings
In order to illustrate more clearly of the technical scheme in the embodiment of the utility model, will make below to required in embodiment
Accompanying drawing is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the utility model,
For those of ordinary skill in the art, on the premise of not paying creative work, can also be obtained according to these accompanying drawings
Other accompanying drawings.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Embodiment one：A kind of dividing head, as shown in figure 1, including for clamping the clamping element 1 of workpiece and for propclip
The support 2 of tight part 1, also include the fixed body 3 that sliding is connected on support 2, through fixed body 3 and with the activity of fixed body 3 even
It is connected to alignment pin 4, integrally formed with square fixing body 9 on clamping element 1, while separates and be fixedly connected with fixing body 9
Positioning disk 5, the middle part of positioning disk 5 are provided with the mounting hole 10 being engaged with fixing body 9, and periphery is provided with several and matched with alignment pin 4
The positioning hole 6 of conjunction, the corner dimension that the line between adjacent positioning hole 6 and the center of positioning disk 5 is formed add equal to workpiece
The angle rotated needed for work, while the anti-shake hole 11 being engaged when the middle part of fixed body 3 is provided with and rotated with mounting hole 10, and
When alignment pin 4 penetrates positioning hole 6, fixed body 3 fits in positioning disk 5.
It is to be attached to positioning disk 5 on fixing body 9 by mounting hole 10 first, so when being processed to workpiece
After move fixed body 3, and fixed body 3 is fitted on positioning disk 5, is then bolted the position of fixed body 3, this
The position that sample allows for positioning disk 5 under the collective effect of fixed body 3 and clamping element 1 has obtained fixation, then wears alignment pin 4
Enter into positioning hole 6, just the position of positioning disk 5 is fixed thus by alignment pin 4, such clamping element 1 is by workpiece clamp
It just can normally be processed after tight, after one section machines, alignment pin 4 is taken out from positioning hole 6, and rotate and determine
Position disk 5, in this process, due to the angle of required regulation when the angle between adjacent positioning hole 6 is equal to work pieces process
Degree, so by the way that alignment pin 4 is penetrated into adjacent positioning hole 6, you can complete the regulation to the angle of positioning disk 5, simply
It is convenient, while be also not in error, so that crudy is higher.
When the workpiece required different rotational angles is adjusted, positioning disk 5 need to only be changed,
During replacing, due to being carried out by fixing body 9 and mounting hole 10 between positioning disk 5 and clamping element 1, so changing
Journey is also simple and convenient；Fixed body 3 is fitted on positioning disk 5 in process, so positioning disk 5 is determined fixed body 3
While position, also make it that the distance between the both ends of alignment pin 4 are smaller, so when positioning disk 5, which has, rotates trend,
The force side of alignment pin 4 and the distance between force side are smaller, and it is also smaller so to allow for the twisting force that alignment pin 4 is subject to,
Protective effect is served to alignment pin 4；Simultaneously because being provided with anti-shake hole 11 on fixed body 3, such fixing body 9 is when rotating
Less abrasion can just occur between fixed body 3, protective effect is served to fixing body 9 so that fixing body 9 can continue
Keep the state combined closely with mounting hole 10, ensure that the precision of processing.
Embodiment two：A kind of dividing head, it is with the difference of embodiment one, it is big that the end of alignment pin 4 is connected with diameter
In the anti-delinking part 7 of alignment pin 4, fixed body 3 is made up of ferrous material, while anti-delinking part 7 is made up of magnetic material, and positions
The rounded structure in end of the pin 4 away from anti-delinking part 7；It is connected between anti-lift-off 8 and fixed body 3 and prevents made of elastomeric material
Lift-off 8.
After anti-delinking part 7 is fixed in the position of alignment pin 4, inhaled by magnetic action on fixed body 3, it is fixed so just to improve
The stability of the position position of pin 4 so that the progress that process can be stablized；Simultaneously when alignment pin 4 is installed, positioning
The fillet structure of the end of pin 4 can to combine between alignment pin 4 and positioning hole 6 it is more convenient, when to 5 turns of positioning disk
When dynamic, connected between alignment pin 4 and fixed body 3 by anti-lift-off 8, so also prevent alignment pin 4 from fixation
Fallen off on body 3, facilitate take next time, it is practical.
It is described above, only specific embodiment of the present utility model, but the scope of protection of the utility model is not limited to
In this, any those skilled in the art is in the change that in technical scope, can be readily occurred in disclosed in the utility model
Change or replace, should all cover within the scope of protection of the utility model.Therefore, the scope of protection of the utility model should be with described
Scope of the claims is defined.
