Description

Glass mold processing built-up jig matched with machining center

Technical field

The utility model belongs to tooling and fixture technical field, and in particular to one kind glass mold matched with machining center adds Work built-up jig.

Background technique

Since the concept of aforementioned machining center can be found in the following patent document for being not limited to enumerate: CN104002200A A kind of (vertical crouch compound multiaxis NC maching center), turnover panel horizontal Machining centers of CN104476215A(), CN104802013B(mono- The numerical control machining center of kind of multi-panel processing), a kind of five-axis NC machine center of CN105364491B(), CN106426590A(number Control glass processing center) and a kind of numerical control machining center of CN206952549U(), etc., thus not reinflated explanation.

It as is known in the industry, can glass mold to Workpiece boring, tapping and milling etc. as workpiece by machining center It is unexceptional, and machining center can also be to glass mold inner cavity depiction, text etc..And then as is known in the industry, it is processing Center to workpiece by technique requirement processing during need Workpiece clamping on frock clamp, and frock clamp is then and in processing The heart matches.

As shown in the above description: frock clamp plays a very important role in the production process of industrial products, glass The production of mold is no exception.So-called frock clamp refers to for being clamped or being positioned to workpiece in machining, with Reach equipment or tool that certain technique requires.Frock clamp usually requires to meet in production without interference phenomenon, positioning Accurate and reliable and easy to operate etc. requires.Since frock clamp has the characteristics that lead to for the exclusive of certain product is manufactured With changing, degree is extremely low, often self manufacture, the production of glass in a manner of cutting the garment according to the figure by the production firm of manufacturing machine product Manufacturer is also generally equipped with various frock clamps in a manner of homemade.

In recent years, the machining center of various medium and high quality is applied by vast medium-sized and small enterprises, is had by Cutter Body Processing with Machining Center product There is the features such as speed is fast, high-quality and standardization level is high, but if lacking frock clamp matched with machining center, that Aforementioned features are just difficult to embody.Using by as the glass mold of workpiece be put to machining center implement such as drill straight hole or tiltedly Hole carves characters, carving, must be pressed from both sides by tooling when being drilled with climbing form hole, milling air drain, mill triangle, mill circular arc and attack the processes such as inner hole thread Tool locks glass mold reliable retention, and frock clamp to the fast clamp of workpiece or release the reliable of the i.e. unlock of clamping with No is the vital factor for guaranteeing Cutter Body Processing with Machining Center efficiency and processing quality.

It is no lack of the technical information of the frock clamp about glass mold processing in disclosed Chinese patent literature, such as awards Weigh notification number CN101659015B(processing glass mold frock clamp), the parallel facing cut of CN103273350B(glass mold The clamp structure of processing), the vessel die clamper of CN101891373B(glassware), CN101891372B(glassware mould Fixture), the clamp structure of CN101898311B(milling positioning reference plane in glass die blank), CN102380777B (grip device of glass mold processing), CN102443859B(are used for the grip device of glass mold processing), The fixture of CN102350650B(glass mold processing), the folder of the improved glass mold processing of CN102350651B(structure Tool device), the turntable type frock clamp of CN102689187A(glass mold processing), CN102848039A(be configured at electrical fire The clamp structure of glass mold formed punch cooling bath processing on flower machine), the fixture of CN102837213A(glass mold processing Structure), the frock clamp of CN102848246A(glass mold processing), the folder of CN102848245A(glass mold processing Lamps structure), the clamp structure of CN103056695A(glass mold inner cavity and joint surface processing), CN107900594A(glass The clamp structure of mold mouth mold die cavity surfacing) and CN103084771A(open-close type shaping mould hinge welding clamping apparatus knot Structure), etc., etc..

Typical " frock clamp of glass mold inner cavity and joint surface processing " recommended such as CN103056693B, this is specially Sharp emphasis compensates for logical disadvantage present in above mentioned CN102380777B, CN102443859B and CN102350650B (for details, reference can be made to the contents in the background technique column of CN103056693B) and objectively embody structure it is terse and can will It reliably clamps and is substantially able to satisfy machining center to glass mold embedded SMA actuators in the two sides of the length direction of glass mold It is required that (for details, reference can be made to the technical effect columns of CN103056693B).But there are following shortcoming: first, due to needing using pressure (there is a pair of of pressuring template at every end) is pushed down in the both ends of the mating surface of glass mold by template, thus causes to generate processing interference feelings Shape is unable to time processing in place, and so-called time processing refers in place: after completing primary clamp, by machining center both name To glass mold die cavity processing (as carve), but mating surface can be processed (roughing of such as mating surface, the finishing of mating surface, Triangle muscle is processed with coincidence or cavity plate is with coincidence processing, the low processing of plane milling and mating surface chamfer machining, etc.), however by this The glass mold that patent clamps needs completing because being unable to satisfy processing request of the machining center to glass mold mating surface Circulation is clamped to subsequent processing and by means of fixture separately after die cavity processing, so that machining center carries out necessity to joint surface Processing, generate investment therefrom manpower be more, online assignment personnel's large labor intensity and influence processing efficiency, and due to throwing Fixture equipment is more and is unfavorable for saving equipment cost；Second, since two sides is provided opposite in the clamping mechanism on base plate (i.e. " left holder and right holder ", the same below) is only fixed with a pair of of T shape screw with the adjustment tank being provided on base plate, thus solid Fixed reliability is difficult to ensure, that is to say, that both two clamping mechanisms and base plate are difficult to obtain desired fiting effect；Third, Due to that need to be operated respectively to aforementioned two clamping mechanism when being clamped to glass mold, thus had an impact to efficiency is clamped；Fourth, Due to lacking to the bearing location measure of glass mold periphery, thus in machining center to existing in glass mold process The anxiety of micro- vast deflection, especially when (patent claims " the sliding seat inclination of sliding seat to the support module between two clamping mechanisms Face ") when failing ideally periphery desired contact with glass mold with the fixing seat inclined surface of fixing seat, foregoing glass mold Deflecting (trembling) situation can be more obvious, influences the processing quality to die cavity；For aforementioned all shortcoming, it is necessary to continue to improve, Technical solution described below generates in this background.
