Description
Technical field
The present invention relates to equation motorcycle race suspension technical field, be specifically related to a kind of university students's equation
Racing car suspension carbon fiber pipe bonding jig.
Background technology
Carbon fibre composite is progressively popularized to civil area from high-end fields such as Aero-Space,
Carbon fiber pipe has the advantages such as proportion is little, rigidity is big, intensity is high, corrosion-resistant, is widely used in medical treatment
In apparatus, sports equipment.But owing to himself characteristic makes the mechanical connection of carbon fiber pipe the most tired
Difficulty, so using glue bonding, becomes a kind of fairly simple efficient connected mode.Nowadays,
FSAE university students's formula car contest uses carbon fiber pipe bonding with metal joint a large amount of
Adhesive product as the guiding mechanism of racing car suspension system.
Suspension is embodied in its kinetic characteristic for dynamic (dynamical) importance and is delivered to from tire
The power on chassis and the response of moment.For the entire vehicle design of equation motorcycle race, suspension property is clearly
Affect the key factor of car load control stability and ride comfort, therefore the design of suspension system sets at car load
In occupation of very important status in meter.By in upper and lower for carbon fiber Successful utilization to suspension system yoke
After, can loss of weight 57%, but selecting carbon fiber pipe is the material of the double transverse arms in independent suspension system
Afterwards, an important problem occurs therewith, be the connection of carbon fiber and metallic article.
Use adhesive that the method needing two parts gluedd joint to stick into a part is referred to as glue to connect.Glue
Connecting fiber destruction minimum, the stress collection of generation is medium and small, and the gross mass finally sticking into a part is little,
Surface unusual light, the processing technology made are the easiest, fabrication and processing cost ratio is relatively low, and compare
Relatively can resist corrosion, the permanent deformation of generation is little.But, it is more difficult to control be glue connect quality,
Transmit very top load as glue connects, then stress can be unreliable.At present, domestic to FSAE carbon fiber
The research of the bonding problem of suspension mainly with Harbin Institute of Technology as representative by changing viscose glue
The factors such as the type of agent, bonding length, bonding gap, surface process carry out improving and studying.
Although achieving certain progress and improvement, but due to the viscose glue mistake at carbon fiber pipe Yu aluminium joint
Cheng Zhong, the impact of anthropic factor is the biggest.Through replica test laggard row data analysis and process,
Just find that the diversity of the adhesive strength of each test specimen is very big, and adhesive strength often occurs not
Satisfactory case.And FSAE racing car is for safety, absolutely not allow that carbon fiber suspension occurs
The probability that adhesive strength is not enough, therefore, the FSAE racing car of many universities transfers to use traditional steel
The suspension transverse arm of system welding.
During common technique for sticking, there is no special jig for cementing, existing fine for carbon
The fixture of dimension pipe is mainly used in punching carbon fiber pipe or surface process, its folder of such fixture
Hold position to be typically at staple joint, and due to the matched in clearance between joint and carbon fiber pipe, because of
The axis of this bonding process center tap and carbon fiber pipe can produce the skew of certain angle each other,
The axiality between carbon fiber pipe and metal joint cannot be ensured after bonding, the most easily occur that glue glues
Connecing a layer skewness, bonding quality is difficult to ensure that unanimously.The tubing folder of existing machining
Tool is for metal tube mostly, owing to metal is bigger with the physical property gap of carbon fiber, it is impossible to straight
Connect the existing tubing fixture of use, and general fixture once can only clamp a pipe fitting, also cannot
Mass production.

In order to make sealing film have certain intensity, the pressure of glue can be born, have again simultaneously
Having the feature of low melting point, convenient thawing, more preferable embodiment is: described sealing film 67
Including plastic layer, the both sides brushing low melt point paraffin of plastic layer, described plastic layer is by EVA and LDPE
Mix, wherein the mass fraction of EVA be the mass fraction of 50%-70%, LDPE be 30%-50%.
According to any one above-mentioned university students's equation motorcycle race suspension carbon fiber pipe bonding jig
Using method, described using method comprises the following steps: preheat, clamping, heating gluing,
Evacuation；
In order to ensure carbon fiber pipe 7 and joint 6 bonding after axiality, should try one's best when both coordinate
Reducing fit tolerance, the internal diameter of most preferably described carbon fiber pipe 7 is slightly less than dome platform 62
External diameter, but such assembling can be more difficult, the most before assembly, needs to carry carbon fiber pipe 7
Before be heated to the first preheating temperature t1, there is thermal expansion after making carbon fiber pipe 7 be heated, such carbon is fine
The internal diameter of dimension pipe 7, slightly larger than the external diameter of dome platform 62, can assemble easily.Therefore described
Preheating steps be: carbon fiber pipe 7 is heated to the first preheating temperature t1, makes carbon fiber pipe 7
Internal diameter slightly larger than the external diameter of dome platform 62；Then two joints 6 are inserted carbon fiber pipe 7
Two ends, and glue is poured in the first permeability hole 63 of end round platform 61 bottom surface, cover blanking cover 65.
Described clamping step is: carbon fiber pipe 7 is placed on adjacent two adjusting screw rods 14 it
Between the front of interstitial site, and with two compress metallic plates 8 respectively with carbon fiber metal pipe 7 liang
The metal joint 6 of end contacts；Then adjust regulation screw 83, make check lock lever 9 seesaw, allow
Two sides of the V-arrangement draw-in groove arranged on it and the sidewall contact of the side of carbon fiber pipe 7, and make
The sidewall of carbon fiber pipe 7 opposite side and the sidewall contact of adjacent two adjusting screw rods 14, make carbon
The circumferential direction of fiber pipe 7 is locked；Then use locking nut 12, lock washer 11 to two
Individual compression metallic plate 8 applies the pretightning force that direction is relative, makes the axial direction of carbon fiber pipe 6 be locked
Extremely；Then by clamping, the bracket cage 13 of carbon fiber pipe 6 slowly snaps in the chute 16 in casing 2
In.
Described heating glue application step is: cover tightly case lid 1, connects the power supply of distribution box 17, makes quiet
Electricity dust-catching board 15 is initially powered up and adsorbs seal box internal dust；Electrical heating is used after certain time

Second permeability hole 64 flows in the gap between carbon fiber pipe 7 and joint 6；Owing to being provided with
One sealing gasket the 69, second sealing gasket 66, glue may not flow in ventilative through hole 68, also will not flow
On earth on the lateral surface of round platform 61, effectively raise bonding quality.
Described vacuum step is: opens vacuum pump 5, is slowly taken out by the air within seal box
Go out, form vacuum environment；After the pressure in seal box reaches certain value, pressurize a period of time is carried out
Vacuum solidification.
In order to accelerate the efficiency of technique for sticking, more preferable embodiment is: described preheating steps
In, joint 6 is heated to the 3rd preheating temperature t3.So can save in heating glue application step and connect
The heat time heating time of 6.Simultaneously in order to ensure that sealing film 67 melts in heating glue application step,
In described preheating steps, the first preheating temperature t1, the 3rd preheating temperature t3 are less than sealed thin
The melting temperature of film 67.
