The quality of product is sufficiently stable；Meanwhile, fixation is played to workpiece during clamping, it is to avoid workpiece occur during processing by
In rigidity is poor and situation about deforming, it is to avoid the generation of waste product, brought convenience to production, solve and deposit in the prior art
The problem of.
The utility model is to solve the technical scheme that is used of above-mentioned technical problem：
The batch machining frock of off-centre operation on a kind of major key body, including clamp body, along clamp body on the circumference of clamp body
Length direction be interval with several workpiece slots, the two ends of clamp body be provided with location-plate, be provided with location-plate and workpiece
Be drilled with positioning hole on the relative locating slot of groove location, location-plate, alignment pin loaded in positioning hole, be also equipped with clamp body by
Workpiece is fixed on the pressing plate on clamp body.
The workpiece slot is 4.
The locating slot is 4.
The pressing plate is 4, is arranged on by bolt on clamp body.
The utility model uses said structure, using can simultaneously four workpiece of clamping frock, can simultaneously to four
Workpiece is processed, and substantially increases production efficiency；Accurate clamping and positioning for workpiece make it that process is no longer complete
By the professional quality and fortune of operative employee so that the quality controllability of workpiece is strong, and the quality of product is sufficiently stable；Meanwhile, dress
Fixation is played to workpiece during folder, it is to avoid the feelings deformed because rigidity is poor occur during processing for workpiece
Condition, it is to avoid the generation of waste product, brings convenience to production；The processing tool effectively utilizes the own characteristic of work piece, makes
Get up relatively simple, reduce production cost.

Embodiment：
For the technical characterstic for illustrating this programme can be understood, below by embodiment, and its accompanying drawing is combined, to this reality
It is described in detail with new.
As Figure 1-5, on a kind of major key body off-centre operation batch machining frock, including clamp body 1, in clamp body 1
Several workpiece slots 101 are interval with along the length direction of clamp body on circumference, location-plate 4 is provided with the two ends of clamp body 1,
Location-plate 4 is provided with the locating slot 401 relative with the position of workpiece slot 101, location-plate 4 and is drilled with positioning hole 402, in positioning hole
Load alignment pin 6 in 402, the pressing plate 2 being fixed on workpiece on clamp body 1 is also equipped with clamp body 1.
The workpiece slot 101 is 4.
The locating slot 401 is 4.
The pressing plate 2 is 4, is arranged on by bolt on clamp body 1.
, it is necessary to by 2 location-plates with interior angle screw loaded on clamp body in the manufacturing process of processing tool, with roughly grinding
Workpiece two ends flat horizontal surface centering two ends locating slot, static balance is then done on lathe, if lay particular stress on if take on clamp body
The method for boring lightening hole, it is ensured that rotation is up to balance, and last trial cut is cut tests to processing tool.
Utilize the processing method using batch machining frock：
By taking the main processing method being healthy and strong in closed type single point press positive clutch as an example, processing method is as follows：
A, sawing machine blanking Φ the 70mm long 410mm of T9 round steel, modifier treatment ensure length in C630 lathe cars both ends of the surface
405mm, beat two ends centre bore.
B, two top clampings, full car are each cylindrical, the cylindrical equal allowance 1.2mm of wherein Φ 60f9, Φ 20h7, and remaining extremely schemes to get the bid
The size of note.
C, on X62W milling machines, using dividing head, top clamping, it is flat to rough mill two ends 20h7, allowance 1.2mm
D, the two top clamping on M1432A grinding machines, corase grind Φ 60f9, Φ 20h7 are cylindrical to Φ 61-0.02-0.04mm、Φ
21-0.02 -0.04mm。
E, M7130 surface grinding machines use mold clamping, corase grind two ends 20h7 it is flat to 21-0.02 -0.04Mm, it is ensured that two ends pair
Claim.
F, by 4 workpiece be arranged on major key body on off-centre operation batch machining frock on, step is as follows：
(1) bolt 3 of pressing plate 2 is unclamped, all pressing plates 2 are rotated to the axial direction of frock, workpiece 5 will have been roughly ground and used it
The flat horizontal surface at two ends is positioned, and is put into the workpiece slot 101 of clamp body 1；
(2) rotary pressure plate 2 to the vertical direction of workpiece 5, tighten bolt 3, make the workpiece pressing 5 of pressing plate 2；
(3) processing tool is arranged on lathe；
G, thick, half smart car off-centre operation, it is ensured that off-centre operation to workpiece circle center distance allowance 0.7-0.8mm.
H, pincers worker carry out chamfered to circular arc everywhere.
I, heat-treatment quenching HRC52-57.
J, by D, E step grind it is each cylindrical and flat to drawing size.
K, by 4 so that Φ 60f9 are cylindrical and the flat positioning of 20h7 is loaded in fixture for grinding machine, R75 off-centre operations are ground.
Dimensional accuracy to the off-centre operation on the major key body using this method processing is checked：
Analyzed in itself from part, the sizes of R75 ± 0.06 can not direct measurement, can only obtain indirectly, so only pass through chi
Very little chain calculating come determine four holes position diameter tolerance range.
According to part in fixture four scheme of installations, chain figure can be drawn to scale, be calculated as follows：In the dimension link
Primary data R1=0A=0B=OC=OD=68, R2=Φ 60H5 ÷ 2=30+0.065mm, A1=37 ± 0.05mm, e=±
0.01mm (this is alignment error of the fixture on lathe), A ∑s=R75 ± 0.05mm, this is closed-loop, and row Size calculation is public
Formula：
A∑max=R1max+A1max-R2min-emin
A∑min=R1min+A1min-R2max-emax
R1=68 ± 0.03mm is solved above, and in order that R75 ± 0.06mm does not make it exceed precision in process
Scope, by R1 tolerance range boil down to R1=68 ± 0.02mm, obtaining R75 ± 0.05mm. with above formula dimension chain calculating can see
Go out, the calculating after compression both ensure that the former R75 margin of tolerance, will not increase difficulty of processing again, it is clear that be feasible.
Above-mentioned embodiment cannot function as the limitation to the utility model protection domain, for the skill of the art
For art personnel, any alternate modification or conversion made to the utility model embodiment all fall within guarantor of the present utility model
In the range of shield.
Part is not described in detail for the utility model, is the known technology of those skilled in the art of the present technique.
