Description
Affiliated technical field
The utility model is the frock clamp in processing wristwatch case body arbor hole, belongs to products radial location, axial location and pilot hole manufacture field.
Background technology
The arbor hole of wrist-watch is the passage that wrist-watch is dialled the arbor of pin adjustment date, time, and the precision in arbor hole can have influence on the accuracy of timekeeping water-proof function of finished product wrist-watch.
Location, the guided tooling in the processing arbor hole that the past is commonly used are too simple.The control of these two frees degree of its axial location and positioning of rotating does not have effective adjusting process.In order to get out the arbor hole that meets drawing requirement, often to use the not Wristwatch case of drillstock axis hole test drilling repeatedly as yet, through test drilling → measure → beat locating element correction → test drilling again ... Repeatedly have a fling to cycle repeats adjustment.Do uniformity promptly time-consuming, that effort is difficult to guarantee the bulk article quality again like this; The fairlead of drill bit is to have breach; Cause drill bit like this in process, the iron filings that drill bit is discharged usually are stuck in the breach, have promptly influenced drill bit row iron filings; Can damage the wiper edges of drill bit again because of barbed portion; Also cause the hole deflection that comes outbreak out easily, whether guide pin bushing only with a screw locking, can't be foreseen the guide pin bushing center and overlap with the arbor hole central shaft of watch shell.
The defective that I exist to this type frock clamp has in the past been done and has been improved design.Adopted the mode of numerical value feedback anchor point, disposable rotary freedom with product is accurately located; Its axial location adopts simple and mode precision horizontal surface grinding machine processing elastic washer height, can be disposable with axial accurately location; Adopt carbide alloy non-notch drill bit fairlead, guarantee that guiding is reliable; Guide pin bushing adopts 8 elastic claw resilient clamp, can change the different guide pin bushing of internal diameter quickly and accurately and guarantees that simultaneously the axis of guide pin bushing overlaps with arbor hole axis.
Summary of the invention
The purpose of the utility model is, a kind of accurate positioning, convenient to operation, the simple and effective frock clamp of guide pin bushing replacing easy, radial and axial location adjustment of adjustment are provided.Aspect adjustment products radial location, two frees degree of axial location, accomplish to know what's what in advance, just make the precision that adheres to specification for the first time.Drill bit guide pin bushing guiding is reliable, and is reliable and stable in the batch machining process, simply and effectively guarantees bulk article arbor hole quality.
The technical scheme of the utility model is following:
The utility model is characterized in that said arbor hole drill hole tool anchor clamps comprise the watch shell clamping device, and radial location mechanism and axial location elastic washer, and this frock clamp also comprises drill bit guiding mechanism and elastic washer disassembly mechanism.
The arbor hole drill hole tool anchor clamps that the utility model provides wherein, adopt interference fits between collet and the support in the said watch shell clamping device, and elastic part is chuck to be the radiation five equilibrium cut open; Collet through cylinder flexible → drive the motion effects that the taper pull bar → male cone (strobilus masculinus) of taper pull bar and the inner conical surface applying → collet of collet receive the taper pull bar; With axially-movable change into radial motion → collet drive elastic washer together the outer surface of radial motion → elastic washer tightly be fitted in the watchcase endoporus; Thereby realize clamping reliably; Be follow-up boring processing action, firm processing basis is provided.
The arbor hole drill hole tool anchor clamps that the utility model provides, wherein, in the described radial location mechanism, side contacts in the fulcrum of transverse arm end and the ear of watch shell is used for the rotary freedom of control table housing; In order to adapt to the variation of the watch shell that varies in size, " Z " axle of radial location mechanism moves and adds dial gauge, is used for feeding back amount of movement; Telescopic arm then can be realized " Y " axial mobile and locking; Transverse arm then can move along " X " axle.This fulcrum can wherein retrain the Z axle that plays decisive role to the watch shell rotary freedom along X, Y, three axially-movables of Z and location, and the mode that adopts dial gauge accurately to feed back Z axial coordinate height guarantees the positioning accuracy of rotary freedom.
The arbor hole drill hole tool anchor clamps that the utility model provides; Wherein, In order to be suitable for the watch shell that endoporus varies in size; Described axial location elastic washer add on the collet one be convenient to make inside and outside coaxial elastic washer, after receiving collet and expanding, shrink, can expand synchronously, shrink; Cannelure is arranged in elastic washer, can be stuck in securely on the collet and be unlikely to free loose or dislocation; Said elastic washer also utilizes suitable thickness that product is carried out axial location except the function of clamping watch shell, the said Y axle in front axial freedom constraint just.
The arbor hole drill hole tool anchor clamps that the utility model provides, wherein, in the described drill bit guiding mechanism, there is self 8 elastic claw the cantilever working end, can grasp guide pin bushing relatively securely, and can guarantee its axiality; Guide pin bushing is to adopt carbide alloy to make, and endoporus and cylindrical are coaxial, when needs are changed guide pin bushing, and only need be with guide pin bushing along axially outwards firmly squeezing out or being squeezed into.When the watch shell external diameter changes, realize the distance adjustment of guide pin bushing distance table housing through set screw and lock screw.The governor motion that the drill bit guiding mechanism adopts is that carbide alloy, endoporus and cylindrical are coaxial, the guide pin bushing that do not have breach and liftable are regulated distance between guide pin bushing and the watch shell is formed.
The arbor hole drill hole tool anchor clamps that the utility model provides, wherein, said elastic washer disassembly mechanism is made up of dismounting pushing block and gantry frame, connects with screw between dismounting piece and gantry frame.The dismounting pushing block is enclosed within on the collet, and gantry frame is connected by two screws with the dismounting pushing block, and frame center in gantry also has one to carry screw.When needs are pulled down collet, only need gantry frame is put into level, screw is coaxial with pull bar, promotes to carry screw → gantry frame → dismounting pushing block → collet with cylinder pushing drawing rod → pull bar and comes off.So just can change the packing ring that adapts to the watch shell that varies in size easily.
