Abstract
The invention discloses a side compressing device of connecting rod sliding block of leak tester, and the side compressing device of connecting rod sliding block of leak tester comprises a down pressing rod and a connecting rod, the down pressing rod and the connecting rod are connected in a detachable mode, the connecting rod drives the first transition section, the second transition section and the third transition section for linkage and drives a moving rail for working, the first transition section, the second transition section and the third transition section are interlocked, a first bracket and a connecting plate are mounted on the moving rail, the first bracket and the connecting plate work together, the connecting plate drives the side seal for working for getting the interlocked impacted state, the loose or disjointed phenomenon caused by cylinder leakage or big detection pressure can be avoided, the shaft pin for each connection part is broken or the parts must be damaged for opening under the impact of the detection pressure, however, the parts are made of the SUS304 material, so the rupture phenomenon cannot be occurred, and the good sealing effect can be obtained.
Description
Technical field
The present invention relates to Wet-dry leak test technology in leakage tester, be applicable to high pressure and the UHV (ultra-high voltage) leak test of automobile air conditioner compressor (vortex and piston type) workpiece.
Background technology
Leak test technology detects a kind of mode that foundry goods leaks, and can solve follow-up turn of leakage of mixing to do over again work by leak test.Present practicality be carry out lateral surface compressing with cylinder, hydraulic cylinder, cylinder and hydraulic cylinder gas leakage or leakage situation lower seal incessantly, can leakage be produced; Simultaneously under low voltage situations, can recoil and make side seal shutoff incessantly in not obvious hyperbaric chamber, easily produces leakage.
Summary of the invention
For problems of the prior art, this technology cylinder drivening rod slide block lateral surface compressing device compresses, and web member band movable slider during operation, with lateral seal on slide block, serves anti-loosening effect, can not leak during sealing.
The technical solution used in the present invention is: a kind of connecting rod slider lateral surface compressing device of leakage tester, it comprises down-pressed pole 1, connecting link 2, First Transition joint 3, second transition segment 4, 3rd transition segment 5, dynamic guide rail 6, first support 7, web joint 8, described down-pressed pole 1 detachably connects with connecting link 2, described connecting link 2 drives described First Transition to save 3, second transition segment 4, 3rd transition segment 5 links, and drive described dynamic guide rail 6 to run, described First Transition joint 3, second transition segment 4, interlock when 3rd transition segment 5 runs, described first support 7 and web joint 8 are installed on described dynamic guide rail 6, described first support 7 runs together with web joint 8, described web joint 8 drives side seal to carry out running thus reaches the state of chain locking compression.
Above-mentioned connecting rod slider lateral surface compressing device, it is further characterized in that: it also comprise the second support 9, rail support plate 10, guide supporting backing plate 11, back up pad 12 and in indirect 13, described 3rd transition segment 5 is by indirect 13 being articulated with in described back up pad 12 in described, described dynamic guide rail 6 runs in described rail support plate 10, and described rail support plate 10 is fixed in described back up pad 12 by described guide supporting backing plate 11; Described First Transition joint 3 is connected on described second support 9, and described second support 9 is fixed in described back up pad 12.
Beneficial effect: the present invention compared with prior art sealing property is higher, maneuverability is stronger, and to environment, the factor impacts such as the temperature of air and humidity there is no, the qualification rate of leak test part is higher than gas circuit air-leakage detector.Enclosure-type can not be leaked gas because of cylinder or hydraulic cylinder or liquid tight seal part occurs to loosen, thus occurs leakage situation.
Accompanying drawing explanation
Fig. 1 is one-piece construction schematic diagram of the present invention.
In figure, 1 is down-pressed pole; 2 is connecting link; 3 is First Transition joint; 4 is the second transition segment; 5 is the 3rd transition segment; 6 is dynamic guide rail; 7 is the first support; 8 is web joint; 9 is the second support; 10 is rail support plate; 11 is guide supporting backing plate; 12 is back up pad; 13 be in indirectly.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
The sealing in the hole of present technical side surface of workpiece seals by hydraulic cylinder or cylinder band dynamic seal, once there is cylinder leakage tester or hydraulic cylinder leakage situation, or detected pressures larger time, will loosen during sealing, cause the defective phenomenon of leak test, and the present invention uses cylinder drivening rod slide block lateral surface compressing device to carry out action, even if cylinder leakage tester and can not loosening, unless there is the fracture of loosening situation connecting rod slider lateral surface compressing device or the breakage of leak test part, so loosen problem when fundamentally solving detection.
As shown in Figure 1, be the connecting rod slider lateral surface compressing device one-piece construction schematic diagram of embodiment of the present invention leakage tester.
It is not only want shutoff top and bottom that workpiece carries out leak test, side is also porose simultaneously will carry out sealing leak test, what prior art was that the sealing of lateral aperture leak test adopts is be with dynamic seal to compress between cylinder or oil cylinder, the connecting rod slider lateral surface compressing device of the leakage tester of the present embodiment, comprise down-pressed pole 1, connecting link 2, First Transition joint 3, second transition segment 4, 3rd transition segment 5, dynamic guide rail 6, first support 7, web joint 8, second support 9, rail support plate 10, guide supporting backing plate 11, back up pad 12 and in indirect 13, described down-pressed pole 1 detachably connects with connecting link 2, described connecting link 2 drives described First Transition to save 3, second transition segment 4, 3rd transition segment 5 links, and drive described dynamic guide rail 6 to run, described First Transition joint 3, second transition segment 4, interlock when 3rd transition segment 5 runs, described 3rd transition segment 5 is by indirect 13 being articulated with in described back up pad 12 in described, and described dynamic guide rail 6 runs in described rail support plate 10, and described rail support plate 10 is fixed in described back up pad 12 by described guide supporting backing plate 11, described First Transition joint 3 is connected on described second support 9, and described second support 9 is fixed in described back up pad 12, described first support 7 and web joint 8 are installed on described dynamic guide rail 6, described first support 7 runs together with web joint 8, described web joint 8 drives side seal to carry out running thus reaches the state of chain locking compression, can not because of cylinder leakage tester or detected pressures large when the imagination of unclamping or throwing off, to make it to open the pivot pin fracture or parts damages that must make each junction under the impact of detected pressures, each parts are SUS304 material, thus phenomenon of rupture can not be there is, thus the sealing effectiveness reached.
The above; such scheme of the present invention all can only be thought explanation of the present invention and can not limit the present invention; claims indicate protection scope of the present invention; and protection scope of the present invention is not pointed out in above-mentioned explanation; therefore; any change in the implication that claims of the present invention are suitable and scope, all should think to be included in the scope of claims.
