Description
Technical field
The utility model is related to technical field of engines, especially cold integrative-structure piston in a kind of insert.
Background technology
High load capacity, detonation pressure engine piston pressure-bearing high, temperature are higher, the easy abnormal in early stage abrasion of first piston ring groove, ring
Groove carbon deposit excessively causes the failures such as snap ring, and current piston conventional solution is resistance to for the first annular groove adds abrasion-proof inserted ring to improve annular groove
Grind, piston crown combustion chamber periphery is cast into as core using the salt core of compacting, salt core is rushed with water again after piston depanning is dissolved
Fall, form interior oil cooling passage and pass through engine cooling spray nozzle Oil injection cooling.Should place resistance to when the piston of this kind of structure is due to casting
Mill insert places salt core again, and operation is cumbersome, easily occurs the fracture of salt core or position deviation etc. in placement process and causes to give up
Product rate is higher, simultaneously because there is a certain distance between this kind of structure salt core and insert, interior oil cooling passage is cold to the first annular groove
But effect is undesirable, it is impossible to fully meets high load capacity, the high-end motor hand of detonation pressure high and is required.
Utility model content
The utility model aims to provide a kind of back side for using and cooling oil duct being directly made in abrasion-proof inserted ring, directly in
Oil cooling passage cools down abrasion-proof inserted ring annular groove, simultaneously because interior oil cooling passage and abrasion-proof inserted ring are made of one, placement operation is fairly simple, position
Put cold integrative-structure piston in accurate insert.
To achieve the above object, the utility model provides following technical scheme：Cold integrative-structure piston in a kind of insert, bag
Piston only is included, cold one weld-ring in abrasion-proof inserted ring is provided with the first annular groove of the piston only, cold one in the abrasion-proof inserted ring
Body weld-ring is by abrasion-proof inserted ring with interior cold ring group into interior cold boxing is connected on the back side of abrasion-proof inserted ring.
As further scheme of the present utility model：The abrasion-proof inserted ring is welded as a whole with interior cold ring.
As further scheme of the present utility model：The cross section of the abrasion-proof inserted ring is trapezoidal, and inner thickness is more than outer
Side thickness, abrasion-proof inserted ring is cast into the head of piston.
As further scheme of the present utility model：The front of the abrasion-proof inserted ring is provided with one ring for laying seal gas ring
Groove.
As further scheme of the present utility model：The interior cold ring inner hollow constitutes interior oil cooling passage.
As further scheme of the present utility model：The material of the interior cold ring is stainless steel plate.
Compared with prior art, the beneficial effects of the utility model are：Cold integrative-structure piston in the insert, using special
Welding procedure will be made with stainless steel plate in cold boxing be connected on the back side of abrasion-proof inserted ring, the two is turned into an entirety, place
Operation is fairly simple, and position is accurate, and the weld-ring of cold integrative-structure in insert is cast into piston crown in piston casting cycle, passes through
Engine cooling spray nozzle oil spout is injected directly into cooling oil chamber, finite reduction the first annular groove temperature.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole

The every other embodiment for being obtained, belongs to the scope of the utility model protection.
Fig. 1 is referred to, in the utility model embodiment, cold integrative-structure piston in a kind of insert, including piston only 1,
Cold one weld-ring 2 in abrasion-proof inserted ring 3 is provided with first annular groove of the piston only 1, cold one weld-ring 2 in the abrasion-proof inserted ring 3
It is made up of abrasion-proof inserted ring 3 and interior cold ring 4, interior cold ring 4 is welded on the back side of abrasion-proof inserted ring 3.
Above-mentioned, abrasion-proof inserted ring 3 is welded as a whole with interior cold ring 4.
Above-mentioned, the cross section of abrasion-proof inserted ring 3 is trapezoidal, and inner thickness is more than thickness as outside, and abrasion-proof inserted ring 3 is cast into piston
Head.
Above-mentioned, the front of abrasion-proof inserted ring 3 is provided with one annular groove for laying seal gas ring.
Above-mentioned, the interior inner hollow of cold ring 4 constitutes interior oil cooling passage, connects oil cooling service pipe.
Above-mentioned, the material of interior cold ring 4 is stainless steel plate.
Design feature of the present utility model and its principle：In order to solve salt core placement location deviation, abrasion-proof inserted ring and salt core
Distance problem, effectively improves interior oil cooling passage cooling effect, and this structure uses the back side that cooling oil duct is directly made in abrasion-proof inserted ring,
Abrasion-proof inserted ring annular groove directly is cooled down using interior oil cooling passage, simultaneously because interior oil cooling passage and abrasion-proof inserted ring are made of one, placement operation
Fairly simple, position is accurate.
Innovative point of the present utility model：Using special welding procedure will be made with stainless steel plate in cold boxing be connected on it is wear-resisting
The back side of insert, makes the two turn into an entirety, directly abrasion-proof inserted ring annular groove is cooled down using interior oil cooling passage, simultaneously because interior cold oil
