Description
Technical field
The present invention relates to a kind of clamping device, belongs to Fixture designing technical field.
Background technology
Bullet punching engine fuel tank pipe joint, more using irregular pipeline casting structure, Fig. 1 is typical case therein
Structural member, its two ends ellipse joint and square joint connect by S-shaped pipeline, the centre-to-centre spacing of two end connectors, and two joints are put down
Row degree and pipeline wall thickness are its critical size.Conventional pipeline processing method adopts fixture clamping parts, first processes an end connector,
Then built-up jig clamping is used, turns around to process another end connector, as shown in Figures 2 and 3.
Using the conventional typical pipe joint foundry goods of processing method processing, because foundry goods uniformity is poor and repeated clamping twice
Produced accumulated error, processes end pipe pipeline connector bias after causing, or even the problems such as gap, as shown in Figure 4.
The content of the invention
In view of this, it is an object of the invention to provide a kind of clamping device of pipe joint foundry goods, is filled using the clamping
Put, pipe joint casting only needs clamped one time, you can completes the processing of two end connectors, eliminates the conformity error of foundry goods, significantly
Improve product quality.
The purpose of the present invention is realized by technical scheme below：
A kind of clamping device of pipe joint foundry goods, the clamping device mainly includes angle block of right angle, fixed clamping plate, pressure
Plate and coupling assembly；
Wherein, the pressing plate includes the first pressing plate, the second pressing plate and the 3rd pressing plate；
Draw-in groove is machined with the plate face of the angle block of right angle side；Handling hole is machined with the fixed clamping plate；
The pipe joint foundry goods is connected by coupling assembly with fixed clamping plate, and by the second pressing plate and the 3rd pressing plate
It is fixed, and the centerline of the end flanges of pipe joint foundry goods two is in same level；The fixed clamping plate clamping is in institute
In stating the draw-in groove on angle block of right angle, and fixed by the first pressing plate, and pipe joint foundry goods pipe joint one end to be processed
Center on the angle block of right angle on the center line of the side end face of undressed groove one.
Further, the coupling assembly includes regulating bolt and self-adaptative adjustment block；One end of the regulating bolt with
The fixed clamping plate is affixed, and the other end is threaded connection with the self-adaptative adjustment block；The self-adaptative adjustment block it is upper
End face is contradicted with the outer surface of the pipe joint foundry goods.
Further, the normal line being provided with fixed clamping plate for checking pipe joint foundry goods whether qualified.
Operation principle：
In the process of the pipe joint foundry goods joint, after an end connector is processed, the first pressing plate is unclamped, will be hung
Ring screw precession handling hole, carries fixed clamping plate and turns around, again in draw-in groove of the clamping on angle block of right angle, and by
One pressing plate is compressed, and reprocesses other end joint.
Beneficial effect
(1) clamping device of the present invention is only needed to pipe joint in the process of the pipe joint foundry goods joint
Foundry goods carries out clamped one time, you can complete the processing of two end connectors, not only effectively reduces mismachining tolerance, and improve product quality is gone back
Shorten the process-cycle of product, it is cost-effective；
The accumulated error of traditional processing method is calculated as shown in formula (1)：
A=A1+A2+A3+A4+A5, (1)
Wherein：The consistent sexual deviation of A1--S pipeline foundry goods straight sections,
The error produced during A2-- processing plug end faces,
The error that A3-- cars frock clamping is produced,
The error that A4-- built-up jigs clamping is produced,
The error that A5-- machined surfaces repeated clamping is produced,
When adding pipe joint foundry goods joint using clamping device of the present invention, because eliminating the consistent of pipe joint foundry goods
Property error, in process only clamped one time, i.e. A1=0；A4=0；A5=0, the then accumulation brought in product quality is missed
Difference only has A2+A3, significantly improves product quality.
(2) position of draw-in groove can ensure the pipe joint foundry goods on angle block of right angle described in clamping device of the present invention
The center of joint one end to be processed is on the angle block of right angle on the center line of the side end face of undressed groove one, you can avoid pipeline
The problem of joint foundry goods two ends pipe joint bias and gap, improve product quality.
(3) clamping device pipe joint clamping of the present invention is on fixed clamping plate, by adjusting regulating bolt, but
The center of the end flanges of pipe joint foundry goods two is in same level, so as to ensure two ends pipe joint in a horizontal plane
On；And ensure that one end of pipe joint foundry goods pipe joint to be processed is always with processing tool by self-adaptative adjustment block
Face contacts；And then bringing into for zero accumulated error is realized, improve product quality.
(4) it is provided with for checking whether pipe joint foundry goods closes on the fixed clamping plate in clamping device of the present invention
The normal line of lattice；Before the pipe joint starts processing, the line on the pipe joint foundry goods and the normal line are entered
Row contrast, if error is more than 0.1mm, illustrates that the line on the pipe joint foundry goods is unqualified or casts unqualified, no longer
The processing of pipe joint is carried out, the production cycle is greatly shortened and is effectively improved yield rate.
