Abstract
The utility model, which provides a kind of automobile exhaust pipe flange assembly for being pressed riveted construction, includes being machined with the flange of clear opening, and press fitting connector is provided with inserted with press fitting annular knurl band tooth bolt, annular knurl band tooth bolt one end in clear opening.It is provided with densely covered sawtooth on the press fitting connector and the contact surface of flange, flange is provided with tooth corresponding with sawtooth and cheats with being pressed on the contact surface of connector, during press fitting in sawtooth insertion tooth hole.The utility model is not on the premise of influencing client and using installation, welded with press fitting riveted replaceable operation chain, desoldering rosin joint risk existing for original welding procedure is reduced, single product manufacturing cost greatly reduces, improves product manufacturing efficiency and the accuracy of manufacture.
Description
Technical field
Automobile exhaust system field is the utility model is related to, is specifically a kind of automobile exhaust pipe flange for being pressed riveted construction
Component.
Background technology
The prior art is by realizing that flange assembly assembles after the free mounting means of bolt or bolt and flange welding.
The assembling of bolt free mounting means is because flange aperture and bolt major diameter fit gap in 1mm or so, are be easy to cause
To filling flange fitting surface deviation, sealing effect and assembling product presentation quality are influenced.
Welding manner for single flange by screw bolt and nut assembly welding, as shown in Figure 1, or by bolt welding in list
Assembled on piece flange with other monolithic flange.
Connected by welding manner, it is professional more demanding to welding operational sequence, and easily form welding position rosin joint
Solder skip, causes weld bolt to come off；Rear bolt installation site temperature distortion is welded, deflection is uncontrollable, it is necessary to by follow-up
Trimming reaches installation dimension precision, but trimming is likely to result in welding position desoldering, this variable is uncontrollable, so that
Client is caused to assemble link problem.
Utility model content
The utility model is in order to solve problem of the prior art, there is provided a kind of automobile exhaust tube method for being pressed riveted construction
Blue component, on the premise of not influencing client and using installation, is welded with press fitting riveted replaceable operation chain, reduces original welding procedure
Existing desoldering rosin joint risk, greatly reduces single product manufacturing cost, improves product manufacturing efficiency and manufacture
Precision.
The utility model includes being machined with the flange of clear opening, inserted with press fitting annular knurl band tooth bolt, annular knurl in clear opening
Band tooth bolt one end is provided with press fitting connector.
Further improve, be provided with densely covered sawtooth on the contact surface of the press fitting connector and flange, flange connects with press fitting
Corresponding with sawtooth tooth hole is provided with the contact surface of head, during press fitting in sawtooth insertion tooth hole.
The utility model beneficial effect is：On the premise of not influencing client and using installation, replaced with press fitting riveted process
Generation welding, reduces desoldering rosin joint risk existing for original welding procedure, single product manufacturing cost greatly reduces,
Improve product manufacturing efficiency and the accuracy of manufacture.
Brief description of the drawings
Fig. 1 is the flange assembly structure diagram of existing welding procedure.
Fig. 2 is the utility model structure diagram.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
The utility model structure is as shown in Fig. 2, the flange including being machined with clear opening, hole tolerance are controlled in basic hole
Footpath-0.1 -0.3Within, in clear opening press fitting connector, bolt are provided with inserted with press fitting annular knurl band tooth bolt, annular knurl band tooth bolt one end
8.8 grades ~ 10.9 grades of intensity requirement grade.
Further improve, be provided with densely covered sawtooth on the contact surface of the press fitting connector and flange, flange connects with press fitting
Corresponding with sawtooth tooth hole is provided with the contact surface of head, during press fitting in sawtooth insertion tooth hole.
The flange assembly of model XS5, original technique are bolt welding flange technique, it is necessary to using CO2Gas shield pair
Part carries out spot welding at 4, and split run production capacity 400, cost accounting is 0.85 yuan of single-piece（Comprising artificial, water, electricity and gas, welding wire etc. into
This）, and the welder that must have specialty is operated, exhaust gas and waste residue cause production environment to pollute during welding, quality of welding spot
Follow-up Special process is needed to carry out the weld strength that peel force detection just can confirm that product, product is in advance in production process, due to
Welder is unskilled, and the quality of solder joint is uncontrolled, causes weldment repeatedly to cause client to complain there are hidden danger of quality.By this reality
With new, by the product for being pressed riveted, it is not necessary to weld, the accuracy of manufacture and size of product are effectively ensured.Product
Production cost single-piece can reduce by more than 0.5 yuan, and be produced without any pollution.
The utility model concrete application approach is very much, and the above is only the preferred embodiment of the utility model, should
Point out, for those skilled in the art, on the premise of the utility model principle is not departed from, can also make
Go out some improvement, these improvement also should be regarded as the scope of protection of the utility model.
