Further, the cone of the lower end is respectively positioned on same axis to the gentle cylinder of guide sleeve to the cone of guide sleeve, upper end.
Further, described bore is equipped with tapered opening portion into guide sleeve；Tapered opening subordinate end is extended with circle
Opening；It the circular open and bores to guide sleeve bottom and offers annular groove, the end face seal gasket is connected in annular groove.
Further, the diameter of the circular open and the diameter of fuse to be measured match, the height of the circular open
For 10 ~ 15mm.
Further, the end face seal gasket is silica gel material, and the end face seal gasket is in round or annular
Any one.
Compared with prior art, a kind of heat exchanger core performing leak test tooling of the utility model, compared to tradition
Circumferential seal structure for pressure test, fuse installation is more quick, by the pushing of cylinder, cone can be made to guide sleeve and end face seal
Gasket quickly positions and seals fuse to be measured；The accuracy rate of test process effectively improves, and original vision manually estimated is avoided to lose
Accidentally；And the test fixture is more environmentally protective, saves water, avoids water pollution.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
As illustrated in fig. 1 and 2, a kind of heat exchanger core performing leak test tooling, including vertical frame 1, the vertical frame
Frame is connected with workbench 2 between 1 lower section, and vertical 1 upper end of frame is connected with support plate 3；2 upper end of workbench is equipped with
It bores to guide sleeve 4；3 upper end of support plate is connected with cylinder 5, and the piston end of the cylinder 5 passes through support plate 3 and is connected with cone guide
Set 4；Described bore is respectively connected with end face seal gasket 6 into guide sleeve 4；The cone of the upper end is provided with gas source in side into guide sleeve 4
Interface 7, described 7 one end of gas source interface pass through end face seal gasket 6 and are connected with fuse 8 to be measured, and the other end is logical across support plate 3
It crosses tracheae 9 and is connected with non-return valve 10, pressure reducing valve 11 and compressed gas source 12 in turn；Between the non-return valve 10 and gas source interface 7
Pick-up sensor 13 is provided on tracheae 9, the pick-up sensor 13 is connect with external alarm.
Further, the cone of the lower end is respectively positioned on same axis to guide sleeve 4 and cylinder 5 to the cone of guide sleeve 4, upper end.
Further, described bore is equipped with tapered opening portion 41 into guide sleeve 4, by tapered opening portion 41 in fuse to be measured
