Description
Technical field
The present invention relates to auto parts machinery manufacture manufacture fields, and in particular to a kind of discrimination pipe fixing device.
Background technique
Manifold is the more complex aluminium alloy castings of a structure, is mainly made of a main manifold and multiple branch pipes, main
Manifold is connected to each branch pipe respectively, and the name of branch pipe is mainly determined by the quantity of branch pipe, for example, gather around there are four point
The manifold of manifold is referred to as four branch pipes.
Manifold in process, is drilled or is polished, for the ease of processing, usually using fixed device to discrimination
Pipe is fixed, then is processed.In secure manifold, the secure manifold by the way of adjusting bolt, the operating time is longer, takes
Manifold inconvenience is put, and when manifold is fixed in bolt, by the way of squeezing manifold, may making manifold, deformation occurs.
Since manifold has rigid requirement for air-tightness, in existing manifold process, air-tightness need to be set
Detection device, but air-tightness detection device is separately provided, the air-tightness of manifold is detected, manufacturing procedure is increased, is made

Controller is additionally provided on 10, the input terminal of controller is electrically connected with two double control switches 7, close to switch 6 respectively, output end difference
It is electrically connected with three indicator lights of red, yellow, and green.
Specific implementation process is as follows:
Four branch pipes 1 are placed in machine table 2, four High pressure air poles 3 are protruded into from the oral area of four branch pipes respectively,
The oral area of main manifold starts air compressor machine towards machine table 2, by the double control switch 7 in machine table 2, at the same controller receive it is double
The electric signal that switch 7 starts air compressor machine is controlled, yellow indicator lamp is lighted；Air compressor machine is inflated into four High pressure air poles 3, four branch pipes
1 is lifted under the action of High pressure air pole 3, and branch pipe is circled using the bottom of High pressure air pole 3 as the center of circle；In four branch pipes
During being lifted, four branch pipes push the locating piece 4 to offset with it, and under the drive of locating piece 4, sliding block 9 is by laterally sliding
The left end of slot 5 is mobile to Sanding Area.
Setting air compressor machine started in 5 seconds in advance, and when the pressure in High pressure air pole 3 reaches threshold value, relief valve starts pressure release, this
When High pressure air pole 3 be in expanded state；Since the cylinder of High pressure air pole 3 is equipped with annular air-pocket 302, and annular air-pocket 302 connects
Logical High pressure air pole 3, when High pressure air pole 3 is in expanded state, annular air-pocket 302 is also at expanded state, 302 envelope of annular air-pocket
The oral area for closing branch pipe, since the High pressure air pole 3 under expanded state pushes against the inner wall of branch pipe；Due to the oral area direction of main manifold
Machine table 2, the gas that relief valve is gone out rush at machine table 2 from the oral area of main manifold, and four branch pipes 1 are by High pressure air pole 3 and main discrimination
The gas that spout part is gone out is fixed, and the height of four branch pipes 1 is determined by the gas that High pressure air pole 3 and main manifold oral area are gone out
It is fixed.
If the air-tightness of four branch pipes 1 is good, the gas in High pressure air pole 3 can only be gone out from the oral area of main manifold, this
When four branch pipes 1 be in machining position, be moved to just with movable slider 9 close to switch 6 by locating piece 4 that four branch pipes 1 push
On induction part, starts manifold sander, polish four branch pipes；Controller receives the electricity of starting manifold sander simultaneously
Signal continues to light yellow indicator lamp.
If the air-tightness of four branch pipes 1 is bad, the gas gone out from main manifold oral area is reduced, and the height of four branch pipes 1 is not
Enough, four branch pipes 1 push the distance of locating piece 4 inadequate, and 9 moving distance of sliding block connecting with locating piece 4 is inadequate, and sliding block 9 cannot
It is moved close on the induction part of switch 6, will be unable to open manifold sander；When controller receives the electricity of starting air compressor machine
It after signal, is delayed 5 seconds, if controller does not receive the signal of starting manifold sander, controller extinguishes yellow indicator lamp, lights
Red indicating light reminds staff to close air compressor machine, replaces four branch pipes 1.After replacing four branch pipes 1, in the reset of spring
Under effect, sliding block 9 is pulled the left end of horizontal concrete chute 5.
In four branch pipes, 1 bruting process, since four branch pipes 1 are polished, the weight saving of four branch pipes 1, while high pressure
Air column 3 and the active force for going out gas from main manifold are constant, therefore the height that four branch pipes 1 are jacked up increases, so that sliding block 9 exists
It is mobile to one end where double control switch 7 in Sanding Area.When the polishing is completed, sliding block 9 just leaves Sanding Area and touches cross
Double control switch 7 into sliding slot 5 closes air compressor machine；Controller receives the electric signal that double control switch 7 closes air compressor machine, control
Device extinguishes yellow indicator lamp, while lighting green indicator light, and staff is reminded to replace four branch pipes 1.
