Description

A kind of air conditioning for automobiles pipeline steeps the assembling device of continuous sheath

Technical field

The present invention relates to the assembling device field that pipeline steeps continuous sheath, especially a kind of air conditioning for automobiles pipeline steeps the assembling device of continuous sheath.

Background technology

Steep the expanded material that continuous sheath is a kind of EPDM; be characterized in that elasticity is big; the coefficient of friction height; a little less than the anti-tear power of pulling; its endoporus undersized is in the external diameter of pipeline; the air conditioning for automobiles pipeline is especially near the pipeline of curling iron and condenser, for the damage that has an accident of anti-pipeline, usually needs the pipeline appearance that elasticity is installed and steeps the protection of continuous sheath.Steep continuous sheath owing to be rubber, the frictional resistance with the pipeline appearance is very big when mounted, too firmly it is broken, and therefore installs very difficult.

Normally before installation, need to carry out preliminary treatment to steeping continuous sheath, be coated with a small amount of refrigeration oil or, lubricate the minimizing resistance so that it increases through hot-water soak as inner chamber.These are handled and can produce many shortcomings, and oiling very easily makes the continuous sheath of bubble be infected with the impurity dirt, and the continuous sheath of bubble can be intake after the hot-water soak, easily pipe fitting is produced corrosion as not drying then.

Summary of the invention

The technical problem to be solved in the present invention is: provide a kind of air conditioning for automobiles pipeline to steep the assembling device of continuous sheath, reduce the assembling resistance between the continuous sheath of bubble and pipe fitting, the installation of being convenient to steep continuous sheath.

The technical solution adopted for the present invention to solve the technical problems is: be used at the continuous sheath of pipe fitting assembling bubble, comprise pipe end holder, air cushion guide rod, fixed base plate, guide rod seat and inlet suction port, the fixed base plate two ends are relatively set with pipe end holder and guide rod seat, one end of pipe end holder fixed fitting, the pipe fitting other end is connected mutually with middle mattress guide rod, the guide rod seat is the air cushion guide rod end of hollow fixedly, and the air cushion guide rod connects inlet suction port, and the air cushion guide rod is provided with aperture.

Further the air cushion guide rod is provided with auxiliary pushing sleeve.

Further the air cushion guide rod passes through guiding connector connecting tube, the link closed end that the air cushion guide rod is connected with the guiding connector, and compressed air sprays from the aperture of air cushion guide rod during work, forms air cushion layer between the continuous sheath of bubble and air cushion guide rod.

The invention has the beneficial effects as follows: air conditioning for automobiles pipeline of the present invention steeps the assembling device of continuous sheath, reduces the assembling resistance between the continuous sheath of bubble and pipe fitting, and the installation of the continuous sheath of convenient bubble is enhanced productivity, and reduces cost.

Among the figure 1, pipe end holder pipe fitting, 2, steep continuous sheath, 3, pipe fitting, 4, the guiding connector, 5, the air cushion guide rod, 51, aperture, 6, fixed base plate, 7, auxiliary pushing sleeve, 8, the guide rod seat, 9, inlet suction port, 10, air cushion layer.

The specific embodiment

In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.

A kind of air conditioning for automobiles pipeline shown in Figure 1 steeps the assembling device of continuous sheath, be used at the continuous sheath of pipe fitting 3 assembling bubbles, comprise pipe end holder 1, aircushion guide rod 5,fixed base plate 6,guide rod seat 8 and inlet suction port 9,fixed base plate 6 two ends are relatively set with pipe end holder 1 andguide rod seat 8, one end of pipe end holder 1 fixedfitting 3, pipe fitting 3 other ends are connected mutually with middlemattress guide rod 5,guide rod seat 8 is aircushion guide rod 5 ends of hollow fixedly, aircushion guide rod 5 connects inlet suction port 9, aircushion guide rod 5 is provided withaperture 51, aircushion guide rod 5 is provided withauxiliary pushing sleeve 7, aircushion guide rod 5 is by guidingconnector 4 connectingtubes 3, the link closed end that aircushion guide rod 5 is connected with guidingconnector 4, compressed air can spray theaperture 51 from aircushion guide rod 5, makecontinuous sheath 2 inner chambers of bubble form one deck air cushion layer and directly do not contact with pipe fitting 3, steepcontinuous sheath 2 and under the support of air cushion layer, can slide along pipe fitting 3 axis easily.Air conditioning for automobiles pipeline of the present invention steeps the assembling device of continuous sheath, reduces the assembling resistance between the continuous sheath of bubble and pipe fitting, and the installation of the continuous sheath of convenient bubble is enhanced productivity, and reduces cost.

During use, at first thefixed base plate 6 with apparatus of the present invention is fixed on the workbench, and leads to compressed air at inlet suction port 9, the morecontinuous sheath 2 of bubble to be installed is inserted in aircushion guide rod 5, end with pipe fitting 3inserts guiding connector 4 then, and the other end is pressed abd fixed on the pipe end holder 1.During work, compressed air sprays from theaperture 51 of aircushion guide rod 5 front ends, form very thinair cushion layer 10 at thecontinuous sheath 2 of bubble and 5 of air cushion guide rods, by promoting auxiliary pushingsleeve 7 thecontinuous sheath 2 of bubble is moved along the axis of aircushion guide rod 5 andpipe fitting 3, need the position until being installed to.

Be enlightenment with above-mentioned foundation desirable embodiment of the present invention, by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the specification, must determine its technical scope according to the claim scope.
