Triple limit-type fuse metal character anchor clamps
Technical field
The utility model relates to a kind of anchor clamps, particularly a kind of triple limit-type fuse metal character anchor clamps that are used for mobile phone plastic fuse metal character operation.
Background technology
In the mobile phone assembly process; Often use hot melting process; Metallic characters belongs to bright spot of cell phone appearance behind the hot melt, not only requires stable performance (can not come off under external force such as metallic characters), and attractive in appearance; This just requires metallic characters and mobile phone plastic accurately to combine closely to be the positioning fixture position between the mould up and down, and the locating cellphone plastic will highly accurately cooperate with position between the mobile phone plastic base.Crimping very easily takes place in metallic characters, dislocation, and leakage glue etc. are bad, for these positions and the defective product of profile (the mobile phone plastic is together with metallic characters), can only scrap, and waste very big.
Summary of the invention
In view of the problem that above-mentioned prior art exists, it is a kind of to needing highly pinpoint triple limit-type fuse metal character anchor clamps that the utility model provides.
The utility model is for realizing above-mentioned purpose; The technical scheme of being taked is: a kind of triple limit-type fuse metal character anchor clamps; It is characterized in that: comprise anchor clamps pressure head fixed head, precompressed lead screw, spring, precompressed piece, hot pressing pressure head, anchor clamps positioning guide column, linear bearing, mobile phone plastic positioning base, metallic characters supplied materials reference column, anchor clamps backplanes support post, clamps base plate; Said hot pressing pressure head is fixed on the anchor clamps pressure head fixed head; Two said linear bearings, two said character supplied materials reference columns are embedded in respectively on the mobile phone plastic positioning base; Said clamps base plate, mobile phone plastic positioning base are fixed together through several anchor clamps backplanes support posts; Wherein the upper end of two foundation plate support columns places two linear bearings on the mobile phone plastic positioning base respectively; Said anchor clamps pressure head fixed head is fixed together through two precompressed lead screw and precompressed piece; Two said springs are enclosed within respectively on two precompressed lead screw between anchor clamps pressure head fixed head and the precompressed piece, and an end of two said anchor clamps positioning guide column is fixed on the bottom surface of anchor clamps pressure head fixed head, and the other end of two anchor clamps reference columns places two linear bearings on the mobile phone plastic positioning base respectively.
The beneficial effect that the utility model produced is: utilize these triple limit-type fuse metal character anchor clamps can make the metallic characters position accurate smooth in the plastic surface; Profile is smooth, attractive in appearance, can significantly reduce the generation of bad substandard products, and can reduce the time of installing with adjustment hot melt anchor clamps, operates more simple and easyly, increases work efficiency.

The specific embodiment
Like Fig. 1,2,3, shown in 4; Triple limit-type fuse metal character anchor clamps comprise anchor clamps pressure head fixed head 1, precompressed lead screw 2, spring 3, precompressed piece 4, hot pressing pressure head 5, anchor clamps positioning guide column 6, linear bearing 7, mobile phone plastic positioning base 8, metallic characters supplied materials reference column 9, anchor clamps backplanes support post 10, clamps base plate 11.The seat surface of mobile phone plastic positioning base 8 is provided with a protruding 8-1, two linear bearing through hole 8-2, six locating piece 8-3, two blind hole 8-4.
Hot pressing pressure head 5 is spirally connected and is fixed on the anchor clamps pressure head fixed head 1; Two linear bearings 7 are embedded in respectively among two linear bearing through hole 8-2 on the mobile phone plastic positioning base 8, and two character supplied materials reference columns 9 are embedded in respectively among two blind hole 8-4 on the mobile phone plastic positioning base 8, and clamps base plate 11, mobile phone plastic positioning base 8 are fixed together through six roots of sensation anchor clamps backplanes support post 10; Wherein the upper end of two foundation plate support columns 10 places two linear bearings 7 on the mobile phone plastic positioning base 8 respectively; Two precompressed lead screw 2 one ends and precompressed piece 4 are spirally connected and are fixed together, and two springs 3 are enclosed within respectively on two precompressed lead screw 2, and two precompressed lead screw 2 other ends and anchor clamps pressure head fixed head 1 are spirally connected fixing; One end of two anchor clamps reference columns 6 is fixed on the bottom surface of anchor clamps pressure head fixed head 1; The other end of two anchor clamps reference columns 6 places respectively in two linear bearings 7 on the mobile phone plastic positioning base 8 and is slidingly matched, and aligns connection with mould about guaranteeing anchor clamps, on the one hand metallic characters and mobile phone plastic is accurately located; On the other hand; The adjustment anchor clamps can conveniently be installed, save time, raise the efficiency.
Precompressed piece 4 is processed into by gathering tetrafluoro sheet material; Hot pressing pressure head 5 is processed into by brass; Anchor clamps pressure head fixed head 1, anchor clamps positioning guide column 6, mobile phone plastic positioning base 8, metallic characters supplied materials reference column 9, anchor clamps backplanes support post 10, clamps base plate 11 are processed by metallic aluminium.
Triple limit-type fuse metal character anchor clamps workflows are following: will need the mobile phone plastic of hot melt to be placed on the protruding 8-1 on the mobile phone plastic positioning base 8; Notice that plastic will be stuck among six locating piece 8-3 that are provided with around the protruding 8-1, the profile of protruding 8-1 and mobile phone plastic internal structure are fitted fully.Pin the mobile phone plastic with hand, the mobile phone plastic in positioning base 8 up and down four direction all can not rock.Then, pick up the metallic characters supplied materials, two locating holes of supplied materials are through respectively on the metallic characters supplied materials reference column 9 on the mobile phone plastic positioning base 8; And be pressed into the bottom of metallic characters supplied materials reference column 9; Guarantee that metallic characters contacts with the applying of mobile phone plastic, both hands are pressed the hot press start button simultaneously, and two anchor clamps positioning guide column 6 on the anchor clamps pressure head fixed head 1 are introduced in the linear bearing 7 on the mobile phone plastic positioning base 8; Precompressed piece 4 is pushed down around the mobile phone plastic fuse metal character then; Last hot pressing pressure head 5 fuse metal characters take off the mobile phone plastic behind the hot melt to mobile phone plastic assigned address, i.e. operation is accomplished.
