Abstract
The utility model relates to a hot plate welding clamp for a filter core of an automobile filter. The utility model is a clamp apparatus which is used during the mutual hot plate welding of a paper filter core and a plastic end cover in the production of filter core components of the automobile filter. The utility model is characterized in that a pair of circular ring-shaped hot plate welding clamps is arranged above the end face of a plastic end cover, which is required to be welded, wherein, the inner wall of the circular ring-shaped clamp presents a hopper shape, namely, the upper half part is an inverted circular table face 1, and the lower half part is a cylindrical face 2; the diameter of the lower cylindrical face is the same with the outer diameter of a finished paper filter core; the intersection angle of the circular table face 1 and the axial line is smaller than 45 DEG. The hot plate welding clamp is designed into two Have-shaped blocks which are closed during welding and opened to come out from the filter core after welded; a Have mold can be closed or opened either in the mode of bidirectional parallel displacement or in the mode that one interface of the Have mold is designed into a rotating shaft in a rotary open-close shape. The adoption of the scheme put forward by the utility model can ensure that when inserted for welding, the paper filter core neither collides with a central pipe nor exceeds the diameter of the end cover, and thereby, processing quality is ensured.
Description
(1) technical field under
The utility model system produces a kind of aid of automobile filter, particularly when producing element sub-assembly of fuel filter, and the grip device that uses when being used for the mutual hot plate welding of paper filter element and plastic end cover.
(2) background technology
Known, a kind of automobile filter, its filter element part are that the centre is a paper filter element by two plastic end covers up and down, are cylindric after being welded to each other and form.
Plastic end cover is the disk shape, and wherein end cap is in order to keep the rigidity behind the filter core outside pressurized in use, at the central portion projection one of end cap pipe shape central tube with holes.
It is cylindric that the paper filter element outside also is, and columned height is made as h, and diameter is made as R.Seem the chrysanthemum shape from the end, central authorities form a circular hole that cooperates with central tube, and diameter is made as r, and R deducts the folding width that poor a behind the r is paper filter element, and folding is reciprocating type, is connected as W without stop, and is also scalable as the wind-box shape of accordion.
In the processing that is welded to each other, vertically to insert earlier with the solder side heat fused of end cap, and then with paper filter element, paper filter element and end cap weld together after the cooled and solidified.
Require the overall diameter R of paper filter element can not surpass the diameter of end cap in welding, the diameter of bore of paper filter element again can not be less than the diameter of central tube, in case break the plastics central tube in the process of paper filter element under inserting in process.Prior art, occur often or, paper filter element internal diameter r is too small slightly, or central tube has the angle position deviation slightly, refill breaks central tube when vertically inserting welding; Perhaps in order not break central tube, the internal diameter r of enlarging paper filter core then often causes external diameter R excessive again slightly, and exceeding end cap directly becomes defective work.
(3) summary of the invention
The purpose of this utility model intends providing a kind of hot plate welding anchor clamps of automobile filter refill, makes that refill neither breaks central tube when vertically inserting welding, does not exceed the end cap diameter again after the fusion of plastic end cover end face, guarantees crudy.
The purpose of this utility model so realizes.
Above the end face that plastic end cover need weld, hot plate welding anchor clamps are set, the inwall of these anchor clamps is funnel-form, and promptly the first half is a reverse frustoconic, and the latter half is cylindrical.The little mesa diameter of reverse frustoconic is identical with the diameter of lower cylindrical shape, and is the same with the paper filter element external diameter of end product.The awl angle that reverse frustoconic side and axis form is less than 45 degree.
Because paper filter element is the accordion bellows-shaped before welding, radially can change its diameter, when the end cap of vertical insertion band central tube, make in it, external diameter amplifies simultaneously, because the paper filter element internal diameter has become big, to can not break central tube, the vertical maximum gauge by central tube when paper filter element, near end cap, when having entered the hot plate welding anchor clamps, the major diameter of great circle entablature can successfully accept to be slightly larger than the paper filter element of end product external diameter, subsequently by the sloping platform face, force paper filter element to close up, external diameter diminishes, when entering cylindrical segment, its external diameter has met the paper filter element external diameter of end product fully, and condensing in end cap becomes certified products.
Welding all is suitable for such hot plate welding anchor clamps to two end cap, after having welded head end lid, even paper filter element has the situation of slightly outwards opening, because acceptance, conical surface guiding, the closing in function of anchor clamps major diameter mouth are arranged, can make external diameter after the last welding of paper filter element meet the dimensional requirement of product fully.
Because the external diameter of plastic end cover is generally slightly larger than the external diameter of paper filter element, to satisfy the functional requirement of postorder assembling and filter core, therefore, the internal diameter of hot plate welding anchor clamps is smaller than the external diameter of end cap.Like this, after all weld at two, filter core can not take off from anchor clamps, and for this reason, the hot plate welding jig Design becomes two semicircular ring Hough shapes, and closure during welding is opened after having welded, and product is deviate from.The closure of Hough mould, opening, both can be two-way parallel the moving in both sides, also can be that an interface at Hough is designed to rotating shaft, becomes rotating open-close shape.
(4) description of drawings
Fig. 1 is the hot plate welding anchor clamps according to a kind of automobile filter filter core that the utility model proposes, a whole set of structure half cut-away view in use.1. hot plate welding anchor clamps rounding table tops among the figure, 2. hot plate welding press cylinders face, 3. end cap anchor clamps, the 4. last plastic end cover of band central tube, 5. paper filter element, 6. bottom end cover.
Fig. 2 is that a kind of automobile filter filter core takes down the view of watching from the end behind the end cap.
Fig. 3 is according to the anchor clamps that the utility model proposes, and contains the plan structure figure of the rotating open-close shape embodiment of rotating shaft.
Fig. 4 is according to the anchor clamps that the utility model proposes, the plan structure figure of the two-way parallel mobile embodiment in both sides.
(5) specific embodiment
In the accompanying drawings, above the end face that the downside plastic end cover need weld, the hot plate welding anchor clamps are set, the inwall of hot plate welding anchor clamps is funnel-form, and promptly the first half is rounding table top (1), and the latter half is the face of cylinder (2).The diameter of lower cylindrical face (2) is the same with the paper filter element external diameter of end product.The round table surface (2) of rounding platform top is spent less than 45 with the angle of axis.The hot plate welding anchor clamps are the annulus mould that a pair of Hough cooperates, the closure of Hough, open, and both can be two-way parallel the moving in both sides, also can be an interface at Hough is designed to rotating shaft, become rotating open-close shape.
