Preferably, the vacuum leak detection auxiliary apparatus, wherein: the diameter of the sealing ball is 36.511-36.515 mm.
The utility model has the advantages that: the vacuum leak detection auxiliary equipment is reasonable in design, simple in structure, low in manufacturing cost and simple and convenient to operate, and the detection efficiency is improved by using the auxiliary equipment, so that the processing efficiency is improved, and the production efficiency is further improved.
Drawings
FIG. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic structural diagram of the test fixture of fig. 1.
Detailed Description
The utility model is further illustrated by the following specific figures and examples.
As shown in fig. 1-2: the utility model provides a vacuum leak detection auxiliary device, wherein: including vacuum pump 1, vacuum pump 1 passes through breather pipe 6 and connects test fixture 4, set up stop valve 2 and manometer 3 on the breather pipe 6 between vacuum pump 1 and the test fixture 4, place on the test fixture 4 and wait to detect part 7, it is sealed through placing the ball sealer 5 of its upper portion to wait to detect part 7, and the diameter of ball sealer 5 is 36.511 ~ 36.515 mm. The part 7 to be detected is provided with a hole, and the size of the hole is matched with that of the sealing ball 5, so that the sealing ball 5 just plays a role in sealing the hole in the part 7 to be detected.
The working steps of the utility model are as follows: after the equipment to be detected is connected according to the mode shown in the figure 1, the connection of the interface is confirmed to be tight, the vacuum pump 1 is started, the whole device is pumped to negative pressure until the pressure gauge displays-67.73 Kpa, under the negative pressure, the pressure gauge value in the detection device keeps the pressure within the range of-67.73 Kpa to-60.95 Kpa within 40 seconds, the part is qualified, if the requirement cannot be met, the part is unqualified, and the vacuum test is carried out after the part is reground.
The vacuum leak detection auxiliary equipment is reasonable in design, simple in structure, low in manufacturing cost and simple and convenient to operate, and the detection efficiency is improved by using the auxiliary equipment, so that the processing efficiency is improved, and the production efficiency is further improved.
Finally, it should be noted that the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to examples, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the claims of the present invention.
