Description
Technical field
The utility model relates to electromagnet structures, especially a kind of for controlling spray in high pressure co-rail diesel EFI engine
The tailstock structure of the high-speed electro-magnet of oily device.
Background technique
Implementation of the country to automobile industry low emission policy, expedites the emergence of the upgrading of engine technology, high pressure co-rail diesel
Electrical Control oil spout technology has reached its maturity and has been promoted at home.High-speed electro-magnet is oil spout in diesel electric-controlled injection system
The crucial control performer of device, effect are execution system ECU instructions, and control pump valve closure is completed fuel oil and precisely sprayed.It wants
Asking electromagnet to have, fast response time, eddy-current loss are low, electromagnetic attraction is big, the characteristics such as small in size.
As shown in Figure 1, the electromagnet tailstock of the prior art is one-piece parts, using whole stainless steel bar, through turning, bore
Repeatedly clamping completes the process the multi-process such as hole repeatedly, and since the structural member (tailstock) is ⊥ type frustum cone structure, selected materials are necessary
Meet diameter be greater than its max architecture size require bar, cause its machining allowance excessive, stock utilization is low, equipment and
Cutter loss is serious, and energy consumption is big, and the process-cycle is long, and work time cost is high, causes structural member (tailstock) production cost to occupy high
Under not, corresponding electromagnetism iron product lacks price competitiveness in the market.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of high-pressure common rail high-speed electro-magnet tailstock structure.
The utility model adopts the following technical solution: including tailstock ontology, the tailstock ontology includes being equipped with central through hole
Pedestal, sleeve and sealing ring, central through hole it is suitable for reading be equipped with assembly sealing ring ring-shaped step, sleeve is equipped with and annular table
The matched ring seat of rank, pedestal are integrated with sleeve by being interference fitted press fitting, and sealing ring is assemblied between ring-shaped step and ring seat,
Sealing ring realizes the sealing to pedestal and sleeve fit-up gap.
Its principle is: under conditions of meeting electromagnet tailstock performance requirement, the utility model is using seperated assembled knot
Structure is composed of the pedestal of metal material, the sleeve of metal material and sealing ring.Pedestal and sleeve pass through interference fit press fitting
It is integrated, sealing ring is assemblied between ring-shaped step and ring seat and is axially compressed, and sealing ring, which realizes, assembles pedestal and sleeve
Effective sealing in gap.Seperated fabricated construction, reduces material cost, improves processing work efficiency, solves former monoblock type knot
The problem of high-speed electro-magnet tailstock high production cost of structure.
A kind of improvement is that the pedestal is made of aluminum alloy materials.Pedestal uses aluminum alloy materials instead, wants meeting performance
Under conditions of asking, material cost is effectively reduced.
The utility model has the advantages that 1, is easy to process, high in machining efficiency.Former integrally-built high-speed electro-magnet tail
The processing of seat need to be completed the process using whole stainless steel bar, and process is more, and it is long to consume working hour.The utility model is according to entirety
The use function and structure size characteristics of the high-speed electro-magnet tailstock of structure, are broken down into pedestal and sleeve two parts, wherein
Base portion is the large scale rotary table part of protocercal tail seat lower end, and turning, bore process processing can be used；Female portion is protocercal tail seat
The small size column part of upper end, material continue to use former stainless steel bar, and bar size is only needed by small size column part most
Big outer diameter reasonably selects, and is processed using turning, bore process.Its process is simplified, and saves machining period.2, material
And processing cost is low.Compared with original integrally-built processing technology, the utility model has machining allowance small, stock utilization
The advantages that height, equipment, cutter loss are small, and energy consumption is few, and the cost of material is low.The base portion of the utility model, rapidoprint
Softer metal bar material (such as aluminium alloy bars) can be used instead, reduce material cost.Using the implementation of aluminium alloy bar production pedestal
Example, production overall cost have dropped 20%, electromagnetism iron product overall cost decline 3.5% or so.3, for different size model
The processing of sub-assembly product, adjustment are flexible and convenient.By adjusting the structure size of corresponding part, a variety of different sizes can be obtained
The sub-assembly of model high-speed electro-magnet tailstock.

Fig. 1 is existing unitarily formed electromagnet tailstock structure schematic diagram.
Fig. 2 is the structural schematic diagram of the utility model.
Fig. 3 is the decomposition texture schematic diagram of the utility model.
In figure: pedestal 1, sleeve 2, sealing ring 3, ring-shaped step 4, ring seat 5.
Specific embodiment
As shown in Figure 2 and Figure 3, a kind of embodiment of the utility model includes tailstock ontology, and the tailstock ontology includes in being equipped with
Pedestal 1, sleeve 2 and the sealing ring 3 of heart through-hole, the ring-shaped step 4 suitable for reading for being equipped with assembly sealing ring 3 of central through hole, on sleeve 2
Equipped with the matched ring seat 5 of ring-shaped step 4, pedestal 1 and sleeve 2 be integrated by being interference fitted press fitting, and sealing ring 3 is assemblied in ring
Between shape step 4 and ring seat 5, sealing ring 3 realizes the sealing to pedestal 1 and 2 fit-up gap of sleeve.
Its principle is: under conditions of meeting electromagnet tailstock performance requirement, the utility model is using seperated assembled knot
Structure is composed of the pedestal 1 of metal material, the sleeve 2 of metal material and sealing ring 3.Pedestal 1 is matched with sleeve 2 by interference
Combined pressure dress is integrated, and sealing ring 3 is assemblied between ring-shaped step 4 and ring seat 5 and is axially compressed, and sealing ring 3 is realized to pedestal 1
With effective sealing of 2 fit-up gap of sleeve.Seperated fabricated construction, reduces material cost, improves processing work efficiency, solves
The problem of former monolithic construction high-speed electro-magnet tailstock high production cost.
A kind of embodiment is that the pedestal 1 is made of aluminum alloy materials.Pedestal 1 uses aluminum alloy materials instead, in satisfaction property
