Fig. 1 is structure schematic diagram of the present utility model；
Fig. 2 is the structure for amplifying simplified schematic diagram of air tightness detection apparatus in Fig. 1.
Specific embodiment
This utility model is further described with reference to specific embodiment and accompanying drawing.
A kind of fixture fail-safe system based on air-leakage test described as shown in Figure 1, Figure 2, for the clamping device 10 on lathe
The Set and Positioning for treating clamping product 15 carries out automatic error identification, its include be fixed positioned in it is several on clamping device 10
Air tightness detection apparatus 11, several air tightness detection apparatus 11 are located at the both sides for treating clamping product 15, and the airtight detection dress respectively
Put 11 and be right against the benchmark position treated on 15 two sides of clamping product；Several air tightness detection apparatus 11 meet at a pressure by trachea
In solenoid 12, there is on the manometer tube 12 baroceptor 13, the baroceptor 13 is electrically connected at the master control of lathe
In system 14.
This utility model simple structure, it is novel in design, by treating clamping product 15 with airtight detection on clamping device 10
Whether the distance between device 11 in place or produces skew judging product clamping, if product Set and Positioning or non-drift condition
Under, air tightness detection apparatus 11 keep constant pressure, lathe normal work together with 12 air pressure inside of manometer tube；If product clamping less than
More than after prescribed limit value, position or skew treat that clamping product 15 is contacted with air tightness detection apparatus 11, air tightness detection apparatus 11 will
Treated that clamping product 15 is extruded so that its internal pressure reduces, so cause the air tightness detection apparatus 11 together with manometer tube 12 inside
Air pressure is reduced, and when the setting minimum pressure of baroceptor 13 is reduced to, then transmits a signal to master control by the baroceptor 13
System processed 14, lathe quit work after recognizing signal, you can prevent in advance to process defective work because clamping is not in place, keep away
Defective products generation is exempted from, has also avoided defective products and flow to client.
Specifically, can realize treating the accurate detection positioning of clamping product 15 to ensure air tightness detection apparatus 11, be located at
Treat that several air tightness detection apparatus 11 of 15 both sides of clamping product are oppositely arranged two-by-two.
It is illustrated as a example by treating clamping product 15 as mainshaft bearing cap below.
Because there is relatively regular or smooth benchmark position as the mainshaft bearing cap both side ends position for treating clamping product 15,
Therefore, 11 quantity of air tightness detection apparatus be four, which is divided into treats 15 both sides of clamping product, and just right two-by-two, and with treat clamping
Benchmark position on 15 both side ends position of product faces.In this example, air tightness detection apparatus 11 with treat the base on clamping product 15
The distance between level be 0.4mm, i.e., using 0.4mm distance as detect predetermined distance scope, when air tightness detection apparatus 11 with treat
The distance between clamping product 15 is respectively less than 0.4mm, then clamping is correct；When air tightness detection apparatus 11 and treat between clamping product 15
Arbitrary distance be more than 0.4mm when, then will occur and extruding will be formed to an at least air tightness detection apparatus 11, and then cause this airtight
Air pressure in detection means 11 reduces, and is detected by baroceptor 13 and transmission signal is into general control system 14, obtained by lathe
Know signal and quit work, the mistake proofing reminding effect not in place to realize clamping.
In concrete such as Fig. 2, generally 11 inner pressure constant of air tightness detection apparatus, and all air tightness detection apparatus 11
And manometer tube 12 keeps constant.Air tightness detection apparatus 11 include base 7 and are fixedly arranged on the locking nut 6 at 7 two ends of base, bottom
The locking nut 6 at seat 7 and its two ends has through through hole；It is connected with inner connecting tube 2, gas-tpe fitting 5 on one locking nut 6 in turn,
The gas-tpe fitting 5 is connected with manometer tube 12 by trachea；The cylinder with a blind end is positioned with another locking nut 6,
There is in the cylinder piston rod 1 of the one end through blind end, the other end is limited in its neighbouring locking screw by wire spring 4
On female 6, there is between the piston rod 1 and blind end O-ring seal 3；Outer sleeve 8 is arranged with outside base 7.
Air tightness detection apparatus 11 can pass through outer sleeve 8 thereon or base 7 or locking nut 6 is welded in clamping device 10
On.
Above the technical scheme provided by this utility model embodiment is described in detail, it is used herein specifically
Individual example is set forth to the principle and embodiment of this utility model embodiment, and the explanation of above example is only applicable to side
Assistant solves the principle of this utility model embodiment；Simultaneously for one of ordinary skill in the art, implement according to this utility model
