Specific embodiment
Below with reference to attached drawing, specific embodiment of the present utility model and embodiment are described in detail, it is described
Specific embodiment only to explain the utility model, be not intended to limit specific embodiment of the present utility model.
It is to be appreciated that present embodiment assumes that product surrounding is now needing to be machined with arc groove just by Four-axis milling
Face, arrow S1 meanings face as shown in Figure 3 need machined surface, and arrow S2 represents that side is machined by other processes.Please together
Refering to Fig. 4, the position degree of arc groove 1 relative to benchmark A, B, C must within Ф 0.02, while two 5.16 holes of Ф position 2 with
Benchmark A, C distance will be in ± 0.01.By to graphic analysis, traditional pressing plate or all unsuitable batch production of vice, base
Quasi- A and C are mutually perpendicular to.In actual location, the clamping device the present embodiment provides accurate camera lens holding parts can be utilized directly
The two datum levels make clamping process more convenient simultaneously to reduce error.
Please refer to fig. 5,4 parts 1 are processed for one group.Precision camera lens clamping zero provided by the utility model
The clamping device of part includes a fixture base 10, an elastic clip fixed 20 and a conicity locking screw 30.The fixture base
10 be the support section of entire clamping device, a square cavities 110 is set to be used to be put into elasticity at the middle part of fixture base 10
Gripping sleeve 20, taper screw 30 and 4 parts 1.Elastic clip fixed 20 is fixed on the middle part of square cavities 110, and 4 parts 1 divide
It is not placed on four angles of square cavities 110；Conicity locking screw 30 passes through the centre bore of elastic clip fixed 20 and locks bottom plate,
Elastic clip fixed 20 is made to generate power outward to be close to be locked with part.
The elastic clip fixed 20 is the core of the clamping device, using elastic preferable 65Mn Steel materials, production
When, the centre bore of elastic clip fixed 20 is processed as to 20 degree of taper hole, then mid diameter removal portion of material adds at cone mouth
Two " ten " word slots of work.Material is thus formed structure as shown in Figure 5, i.e., described elastic clip fixed 20 includes pedestal 210 and sets
It puts 4 angles of pinching, 220,4 angles of pinching 220 on pedestal 210 and surrounds centre bore, centre bore is 20 degree of taper hole（Such as Fig. 8 institutes
Show, α is 20 degree）.
Four sides of the square cavities 110 are being pressed from both sides as the processing A origin reference location faces of part and C origin reference location faces
Tool processing when must assure that its be mutually perpendicular to and and plane perpendicular, as shown in Figure 6.
In further embodiment, 4 angles of the square cavities 110 do circular arc and keep away position, i.e., 4 right angles are set as circular arc
Shape, in order to avoid generate positioning interference with part 1.
The operation principle of the clamping device of the precision camera lens holding parts is:
First elastic clip fixed 20 is fixed in fixture base 10, conicity locking screw 30 is passed through in elastic clip fixed 20
Heart via simultaneously locks bottom plate, at this time can be empty with the elasticity of testing elastic gripping sleeve by locking and unclamping conicity locking screw 30
Between.
On the four of square cavities 110 angles that 41 one groups of parts are put into fixture base 10, conicity locking is uniformly locked
Screw, under taper effect, elastic clip fixed 20 generates power outward in four direction, and part, such as Fig. 7 are locked on 45 degree of directions
Shown in Fig. 8, the A origin reference locations of the part C1 benchmark with fixture base simultaneously in A1 and C origin reference locations are may insure at this time
Side is bonded completely, also ensures that the clamping requirement of part, as shown in Figure 9.
Completion of processing need to only unclamp conicity locking screw and can be taken off 4 parts, you can start processing next time.Using this
Four sides of the square cavities 110 of holding jig pedestal is needed to clean during clamping device, to prevent generating position error.
In conclusion clamping device provided by the utility model need to only be inserted into conicity locking screw, you can realize one time 4
The clamping of part, operation is very easy and reduces operation intensity, is promoted through surveying production efficiency by original 64% to 91%,
And defective products greatly reduces, and improves the quality of product, is suitble to produce in enormous quantities.
It should be understood that the above is only the preferred embodiment of the utility model only, it is not sufficient to limit this reality
With novel technical solution, for those of ordinary skills, within the spirit and principles of the present invention, Ke Yigen
Increased and decreased according to above description, replaced, converted or improved, and all these technical solutions, it should all belong to appended by the utility model
