Description
Technical field
The utility model belongs to vavuum pump appliance technology, more particularly to a kind of anti-fracture fast-spliced vavuum pump.
Background technology
The combining form of former air nozzle connector and vavuum pump body, after two part injection moldings, using frock clamp,
Working of plastics special-purpose ultrasonic bonding machine or plastics machine Special rotary fusing soldering welder, combine two individual parts.Such welding
Failure welding can be caused, the problems such as caused endoporus crosses weldering carbon distribution, and sealing is poor, low production efficiency, and percent defective is high.And this product
Applied on new-energy automobile, working of plastics needs enough mechanical strengths, excellent dimensional stability and heatproof, weatherability, institute
Using PA66+GF30, in working of plastics industry, to add plastic welding practices parameter, frock clamp positioning and the fusion character of glass
Difficulty is all bigger, can not 100% ensure sealing property, percent defective is higher, need to be detected through 100% sealing property.
The content of the invention
The purpose of this utility model is solve the problems, such as techniques discussed above, there is provided one kind makes air nozzle connector be melted with body
It is integrated, fully ensures that structural strength and the air-tightness requirement of air nozzle connector and vavuum pump junction, prevent using process
The anti-fracture fast-spliced vavuum pump of middle rotation, its technical scheme are as follows：
Anti-fracture fast-spliced vavuum pump, including body and air nozzle connector, it is characterised in that offered on air nozzle connector
Air chamber, annular groove and anti-rotation boss are offered on one end of air nozzle connector, and air nozzle connector is provided with one end of annular groove and anti-rotation boss
End is equipped with valve plug by step, and air nozzle connector offers stomata at valve plug, the valve after assembling
Joint and the positioning of valve plug are arranged in body mold, and air nozzle connector and valve plug contain in embedded body when body is molded
Fusion integral structure completely is formed with body.
Preferred embodiment is that described anti-rotation boss sets some friction protrusions.
Anti-fracture fast-spliced vavuum pump provided by the utility model, when in use, annular groove and anti-rotation boss master
If there is enough anti-rotations and anti-dropout intensity after being combined for air nozzle connector with body.Valve plug and air nozzle connector
Assembly method effect is convenient, fast, is easily realized, cost is low.The combining mechanism master of air nozzle connector and valve plug and body
It is the structural strength and air-tightness requirement fully ensured that to act on.
The utility model sets some friction protrusions.There can be more preferable frictional behaviour so that when body is molded
Wait, the fusion of body and air nozzle connector has more intensive properties, difficult for drop-off.
The beneficial effects of the utility model are：Air nozzle connector and body is fused to be integrated, fully ensure that air nozzle connector and
Structural strength and the air-tightness requirement of vavuum pump junction, prevent the anti-fracture fast-spliced of air nozzle connector in use
Vavuum pump rotates.
Brief description of the drawings
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is the schematic diagram of air nozzle connector.
Embodiment
With reference to Fig. 1 and Fig. 2 specific illustrative embodiments：
Anti-fracture fast-spliced vavuum pump, including body 1 and air nozzle connector 2, air chamber 3, gas are offered on air nozzle connector 2
Annular groove 4 and anti-rotation boss 5 are offered on one end of mouth joint 2, air nozzle connector 2 is provided with the end of one end of annular groove 4 and anti-rotation boss 5
Valve plug 6 is equipped with by step at face, air nozzle connector 2 offers stomata 7 at valve plug 6, the gas after assembling
Mouth joint 2 and the positioning of valve plug 6 are arranged in body mold, and air nozzle connector 2 and valve plug 6 contain embedding when body 1 is molded
Enter and form fusion integral structure completely in body with body.
Preferred embodiment is that described anti-rotation boss sets some friction protrusions.
Specifically used when, the air nozzle connector of working of plastics, the valve plug of working of plastics, noted by a set of multi-cave mould
The type of being moulded into obtains, and air nozzle connector is molded to obtain with valve plug using same set of plastic mould, directly uses manual assembly mode,
Valve plug is pressed into the end of air nozzle connector, there is step positioning air nozzle connector end, it is ensured that the rigging position of valve plug
And uniformity；Air nozzle connector devises annular groove and anti-rotation boss in structure, it is ensured that prevents after chimeric with body with enough
Turn and anti-dropout intensity.
Again by the air nozzle connector after assembling, by the positioning form on body injection mold, body is molded, in high temperature, height
Pressure, the material Fast Filling mold cavity of body, makes plastics contain air nozzle connector, valve plug, the joint portion of body rapidly
Position, reach being permanently embedded and fusing state completely for part.
After last body assembly shaping, stomata carries out lead plug processing using platform work drilling machine, ensures that body leads to 2 air chambers
Hole is communicated, and handling ease is realized, equipment cost input is relatively low.
The injection molding of the utility model structure is fitted together to mode, and production efficiency is high, high mechanical strength, good seal performance.Meanwhile
Equipment cost input is low, and production efficiency is high, and debugging percent defective is low, the target of cost of implementation control.
Machining accuracy is high, and production efficiency is fast, and quality level is high, can realize that equipment automatization assembly technology produces, assembling section
Clap fast function.
