Abstract
The utility model provides a piston is refused and is processed special split type location tang mould, include the split type tang placenta that constitutes by chassis and tang tire bead, a terminal surface upper shaft on chassis has the piston body locating piece to the extension, the threaded hole of circumference equipartition on the chassis, tang tire bead suit is on the piston body locating piece, the terminal surface at tang tire bead both ends is the tang tread, be equipped with the counter sink of circumference equipartition on two tang treads respectively, counter sink staggered arrangement on the face of tang tire bead both ends, counter sink on the tang tire bead is corresponding with the screw hole on the chassis, the tang tire bead passes through countersink bolt and is connected with the chassis. This split type tang placenta has the advantage that simple structure, convenient to use, cost of manufacture are low, reduce the wasting of resources.
Description
Technical field
The utility model belongs to piston remelting processing accessory, and special Split Positioning seam allowance clamping fixture is processed in especially a kind of piston remelting.
Background technology
Along with the further expansion of recent year, international heavy goods vehicles demand, engine is to high loading, superpower, high strength future development, more and more higher to the requirement of piston performance, crack for stoping piston to burn in the environment of high temperature, have employed advanced Technology For Remelting, utilize mother metal to carry out refuse at piston combustion chamber throat periphery, the guarantee mileage of piston obtains prolongation, improve the competitive power of product, reduce product failure reparation.
At present, piston is made up of the combustion chamber at piston body and top.Need special positioning spigot mold to coordinate during piston remelting, just can complete remelting practice.The structure of the special positioning spigot mold of existing piston is: comprise the seam placenta can installed on the spinning device, and the center of seam placenta is provided with the preset pieces of location, clamping piston body.But in the process of piston remelting, produce the problem of positioning spigot placenta scaling loss and piston seam positioning datum destruction, cause processing waste product high, production efficiency is low, fails for a long time to be solved.
Summary of the invention
The utility model provides a kind of piston remelting to process special Split Positioning seam allowance clamping fixture, in order to avoid the problem that positioning spigot placenta scaling loss and piston seam positioning datum destroy.
In order to solve the problems of the technologies described above, technical solutions of the utility model are: special Split Positioning seam allowance clamping fixture is processed in a kind of piston remelting, it is characterized in that: comprise the split type seam placenta be made up of chassis and seam tyre bead, one end face on chassis is axially extended with piston body preset pieces, chassis is evenly distributed in threaded hole, seam tyre bead is set on piston body preset pieces, the end face at seam tyre bead two ends is seam tyre surface, two seam tyre surfaces are respectively equipped with the counter sink of circumference uniform distribution, counter sink staggered arrangement in seam tyre bead both ends of the surface, counter sink on seam tyre bead is corresponding with the threaded hole on chassis, seam tyre bead is connected with chassis by countersunk screw.
Beneficial effect: split type seam placenta has the following advantages: 1. in use procedure, after the seam treadwear of seam tyre bead one end, using seam tyre bead other end as seam tyre surface, thus realize the nonexpondable object of seam tyre bead, improve working efficiency, ensure that quality product, and reduce cost.2. the counter sink staggered arrangement in seam tyre bead both ends of the surface, is convenient to after making seam tyre bead change face install.3., when whole mold cannot realize locating piston seam, only need change seam tyre bead, this avoid the problem that whole mold is scrapped, thus reduce cost.3. this split type seam placenta has the advantage that structure is simple, easy to use, cost of manufacture is low, reduce the wasting of resources.

Fig. 3 is seam tyre bead schematic cross-section in the utility model.
Embodiment
As shown in Figure 1, Figure 2 and Figure 3, special Split Positioning seam allowance clamping fixture is processed in a kind of piston remelting, comprise the seam placenta be made up of chassis 1 and seam tyre bead 2, one end face on chassis 1 is axially extended with piston body preset pieces 3, chassis 1 is evenly distributed in six threaded holes 4, chassis 1 is connected with swivel arrangement by the bolt in three threaded holes 4 on it, realizes chassis 1 and rotates; The shape of seam tyre bead 2 is ring-type, the end face at seam tyre bead 2 two ends is seam tyre surface, two seam tyre surfaces are respectively equipped with three counter sinks 5 of circumference uniform distribution, counter sink 5 staggered arrangement in seam tyre bead 2 both ends of the surface, namely the counter sink 5 on seam tyre bead 2 one end face is corresponding with the One On The Chassis threaded hole 4, change behind seam face until seam tyre bead 2, the counter sink 5 on seam tyre bead 2 other end is corresponding with the One On The Chassis threaded hole 4; Seam tyre bead 2 is connected with three threaded holes 4 remaining on chassis 1 by the countersunk screw in counter sink 5, realizes seam tyre bead 2 and is fixed on chassis 1; Piston body preset pieces 3 is technology well known in the art, for elaborating.
Principle of work: when the seam treadwear of seam tyre bead one end, polishes flat the seam tyre surface of wearing and tearing, is then installed on chassis by seam tyre bead, makes the other end of seam tyre bead as the seam tyre surface of positioning piston body.
Do not elaborate in this specification sheets part, is technology well known in the art.
