Description
Technical field
The utility model relates to a kind of leak-checking apparatus that whether has leak source for detection of pipe.
Background technology
The pipe of making for injection moulding or compacting at present adopts image to detect when whether test exists leak source usually or bubble detects.Wherein the image detection because of the needs supporting surface, so there is certain dead angle, can not detect substandard products fully in streamline, needs duplicate detection; When bubble detects some iron piece detected, it is got rusty, and carry out bubble and detect in the lower situation of temperature in winter, the operative employee is not easy to operate.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of detect easy, accuracy rate is high, can not be to the pipe leak-checking apparatus of workpiece injury.
For addressing the above problem, the technical solution adopted in the utility model is: the pipe leak-checking apparatus, comprise base, be provided with pipe fixing device in the base, the pipe of required detection is arranged in the pipe fixing device, be provided with left support abutment and right support abutment on the described base, be provided with transversely movable left axle in the left support abutment, the right part of left axle is provided with left block, be provided with transversely movable right axle in the right support abutment, the left part of right axle is provided with right block, be provided with inlet channel and sense channel in the right block, the right-hand member of inlet channel connects compressed air source, the right-hand member Bonding pressure sensor of sense channel, and the position of left block and right block is corresponding with the two ends of the pipe of required detection respectively.
The structure of described pipe fixing device comprises the motor that is arranged on the base, is provided with rotating disk on the output shaft of motor, and the edge is arranged circumferentially the draw-in groove that several match with the pipe diameter of required detection in the rotating disk.
Be provided with circular groove in the right side of described left block, the diameter of circular groove is less than the left end diameter of the pipe of required detection, and the position of circular groove is corresponding with the position of the pipe of required detection.
The beneficial effects of the utility model are: above-mentioned lid leak-checking apparatus, and it is simple in structure, easy and simple to handle, by air pressure pipe is detected, and Detection accuracy is high, and can be to the workpiece injury.

Among the figure: 1, base, 2, left support abutment, 3, right support abutment, 4, left axle, 5, left block, 6, right axle, 7, right block, 8, inlet channel, 9, sense channel, 10, motor, 11, rotating disk, 12, circular groove, 13, the pipe of required detection.
Embodiment
Below by specific embodiment the utility model pipe leak-checking apparatus is described in further detail.
Such as Fig. 1, shown in Figure 2, the pipe leak-checking apparatus, comprise base 1, be provided with pipe fixing device in the base 1, the pipe 13 of required detection is arranged in the pipe fixing device, be provided with left support abutment 2 and right support abutment 3 on the described base 1, be provided with transversely movable left axle 4 in the left support abutment 2, the right part of left axle 4 is provided with left block 5, be provided with transversely movable right axle 6 in the right support abutment 3, the left part of right axle 6 is provided with right block 7, be provided with inlet channel 8 and sense channel 9 in the right block 7, the right-hand member of inlet channel 8 connects the compressed air source (not shown), the right-hand member Bonding pressure sensor (not shown) of sense channel 9, and the position of left block 5 and right block 7 is corresponding with the two ends of the pipe 13 of required detection respectively.
As preferred version, the structure of described pipe fixing device comprises the motor 10 that is arranged on the base 1, is provided with rotating disk 11 on the output shaft of motor 10, and the edge is arranged circumferentially the draw-in groove that several match with pipe 13 diameters of required detection in the rotating disk 11.
As preferred version, be provided with circular groove 12 in the right side of described left block 5, the diameter of circular groove 12 is less than the left end diameter of the pipe 13 of required detection, and the position of circular groove 12 is corresponding with the position of the pipe of required detection 13.
Principle of work of the present utility model is: the pipe 13 of required detection is arranged in the draw-in groove of rotating disk 11, and along with the rotation of motor 10, rotating disk 11 one by one station rotates realization and detects one by one.During detection, left axle 4 and right axle 6 in left support abutment 2 and the right support abutment 3 move to the direction of pipe respectively, so that sealing with the two ends of pipe 13 mutually with right block 7, left block 5 contacts, inlet channel 8 and the sense channel 9 that be arranged in right block 7 this moment all are connected with the tube chamber of pipe 13, pressurized air in the compressed air source enters tube chamber inside from inlet channel 8, make tube chamber inside have certain pressure, when reaching set pressure, stop air inlet, and can keep within a certain period of time by pressure transducer detector tube cavity pressure, if keep, illustrate that then this pipe is certified products; Have leak source such as pipe, then intraluminal pressurized air can be revealed from leak source, and the tube chamber internal gas pressure is descended, and can detect by pressure transducer this moment, illustrates that then this pipe is unacceptable product.When the left end of the pipe 13 of required detection is that enclosed construction is, because the setting of circular groove 12, in the left side of pipe as exist leak source also can detect, thereby the dead angle that can avoid detecting exists.
The above embodiments are principle and the effect thereof of illustrative the invention only, and the embodiment of part utilization, but not is used for restriction the utility model; Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
