Abstract
The utility model provides a kind of air tightness detection apparatus, it is made up of base, O-ring seal, guide sleeve, lead etc., compressed air introduced below when using on base with cylinder rod mating holes, pressing plate and lead I, lead II are lifted in the presence of cylinder rod, and there is very wide arc gap between the hole coordinated due to cylinder rod and with it, compressed air can have certain leakage, and flowmeter is able to detect that compressed air leakage amount；When the wheel lower surface of any diameter dimension is put into above pressing plate, in the presence of wheel own wt, pressing plate is depressed with lead I and lead II；Cylinder rod is also depressed simultaneously, and its lower surface compresses O-ring seal, and compressed air is no longer leaked, and can judge whether workpiece is placed completely by flow count value finishes.
Description
Technical field
The utility model is related to airtight detection during a kind of a kind of air tightness detection apparatus, specifically wheel Set and Positioning
Device.
Background technology
In the machining production process of aluminum-alloy wheel, automaticity more and more higher, most enterprises are all real
Showed robotic processing, but in the production process of automation, in order to ensure the safety of personnel and equipment, in machine plus
Air tightness detection apparatus is generally required on clamping apparatus, with whether complete Set and Positioning before detecting work pieces process.However, passing
The air tightness detection apparatus of system can only adapt to a wheel-type, need frequently to adjust its position for different wheel-type, very time-consuming
Arduously, and often there is airtight take-off lever clamping stagnation, it is impossible to the phenomenon being depressed.
The content of the invention
Whether the purpose of this utility model is to provide for a kind of air tightness detection apparatus, can detect wheel on fixture
Clamping is finished, and is capable of the wheel of compatible different-diameter size.
To achieve these goals, the technical solution of the utility model is：A kind of air tightness detection apparatus, by base, O-shaped close
Seal, guide sleeve I, lead I, stop screw I, cylinder rod, pressing plate, guide sleeve II, II group of stop screw II and lead
Into guide sleeve I and the hole of chassis left side are interference fitted；Lead I is arranged on lower section on the left of pressing plate, is slidably matched with guide sleeve I,
Fit clearance 0.05mm；Stop screw I is arranged on the left side of base, and its output end coordinates with the guide groove on lead I；Cylinder rod
Coordinate with the interporal lacuna in the middle of base, fit clearance 0.5mm；O-ring seal is placed in the lower end of cylinder rod；Guide sleeve II is right with base
The hole interference fit of side；Lead II is arranged on pressing plate lower right-hand side, is slidably matched with guide sleeve II, fit clearance 0.05mm；
Stop screw II is arranged on the right side of base, and its output end coordinates with the guide groove on lead II.
Cylinder rod top is in circular arc, and is not connected with pressing plate；There is an a diameter of Φ A hole lower section, and Φ A are less than cylinder rod
Outside diameter.
When actual use, with the compressed air introduced below of cylinder rod mating holes on base, the pressing plate in the presence of cylinder rod
It is lifted with lead I, lead II, and there is very wide arc gap, compressed air meeting between the hole coordinated due to cylinder rod and with it
In the presence of certain leakage, flowmeter is able to detect that compressed air leakage amount；The wheel lower surface of any diameter dimension is put into
When above pressing plate, in the presence of wheel own wt, pressing plate is depressed with lead I and lead II；While cylinder rod
It is depressed, its lower surface compresses O-ring seal, and compressed air is no longer leaked, can judges that workpiece is by flow count value
No complete placement is finished.
The utility model is generally used on fixture wheel, can detect whether clamping is finished wheel on fixture,
And it is capable of the wheel of compatible different-diameter size；While having, simple in construction, accuracy of detection is high, performance safety is stable, be fabricated to
This low feature.
Brief description of the drawings
Fig. 1 is a kind of front view of air tightness detection apparatus of the utility model.
In figure, 1- bases, 2-O types sealing ring, 3- guide sleeves I, 4- leads I, 5- stop screws I, 6- cylinder rods,
7- pressing plates, 8- guide sleeves II, 9- stop screws II, 10- leads II.
Embodiment
Below in conjunction with the accompanying drawings explanation according to the utility model proposes specific device details and working condition.
The device by base 1, O-ring seal 2, guide sleeve I 3, lead I 4, stop screw I 5, cylinder rod 6, pressing plate 7, lead
Constituted to set II 8, stop screw II 9 and lead II 10, guide sleeve I 3 and the hole in the left side of base 1 are interference fitted；It is oriented to
Post I 4 is arranged on the left side of pressing plate 7 lower section, is slidably matched with guide sleeve I 3, fit clearance 0.05mm；Stop screw I 5 is arranged on bottom
The left side of seat 1, its output end coordinates with the guide groove on lead I 4；Cylinder rod 6 coordinates with the interporal lacuna in the middle of base 1, coordinates
Gap 0.5mm；O-ring seal 2 is placed in the lower end of cylinder rod 6；Guide sleeve II 8 and the hole on the right side of base 1 are interference fitted；Lead II
10 are arranged on the lower right-hand side of pressing plate 7, are slidably matched with guide sleeve II 8, fit clearance 0.05mm；Stop screw II 9 is arranged on bottom
The right side of seat 1, its output end coordinates with the guide groove on lead II 10.
The top of cylinder rod 6 is in circular arc, and is not connected with pressing plate 7；There is an a diameter of Φ A hole lower section, and Φ A are less than cylinder
The outside diameter of bar 6.
In the course of the work, the compressed air introduced below on base 1 with the mating holes of cylinder rod 6, in the presence of cylinder rod 6
Pressing plate 7 and lead I 4, lead II 10 are lifted, and there is very wide arc gap, pressure between the hole coordinated due to cylinder rod 6 and with it
Contracting air can have certain leakage, and flowmeter is able to detect that compressed air leakage amount；By under the wheel of any diameter dimension
When end face is put into 7 top of pressing plate, in the presence of wheel own wt, pressing plate 7 is pressed with lead I 4 and lead II 10
Under；Cylinder rod 6 is also depressed simultaneously, and its lower surface compresses O-ring seal 2, and compressed air is no longer leaked, and passes through flow count value
It can determine whether whether workpiece is placed completely to finish.
