Abstract
The utility model provides a blockage device for the detection of the airtightness of a workpiece. The blockage device comprises a shell and a base; openings are formed in the upper and lower ends of the shell; an inner hole penetrating through the openings in the upper and lower ends is formed in the shell; the base is arranged in the opening in the lower end of the shell; a mounting seat is arranged at the upper end of the base; a guide inner pin is arranged on the mounting seat; an expansion rubber sleeve is arranged between the guide inner pin and the shell; an air inlet is formed in the bottom of the expansion rubber sleeve; an inflating port is formed in the outer wall of the base; an inflating path communicated with the air inlet of the expansion rubber sleeve is arranged in the base. When the blockage device for the detection of the airtightness of the workpiece is used, a workpiece pipe is sealed by inflating the inner cavity of the expansion rubber ring, and the blockage difficulty is reduced and the strict demands on the workpiece position are reduced. The blockage device is fully suitable for the automatic detection production line, so the production efficiency is improved, the demands on personnel are lowered, the structure is simple and the maintenance is convenient.
Description
Technical field
The utility model relates to a kind of blocking device that detects, especially a kind of blocking device detecting for Work piece sealing.
Background technique
At present, auto parts and components workpiece in the time carrying out sealing propertytest, need to be with block head by the import and export shutoff of workpiece and ensure that leak detector communicates with heat exchanger inside by this block head, make itself and atmosphere environment form isolation.The blocking device bad adaptability of traditional approach, the pipeline system that can not meet automation detects.
Summary of the invention
The purpose of this utility model is to provide a kind of blocking device detecting for Work piece sealing, can improve the adaptability of blocking device, adapts to automation and detects production line, enhances productivity.
In order to solve the problems of the technologies described above, the technical solution of the utility model is as follows: a kind of blocking device detecting for Work piece sealing, it is characterized in that: comprise shell, base, described shell upper, lower end is respectively equipped with opening, in housing, be provided with in perforation, the endoporus of lower ending opening, floor installation is in the opening of housing lower end, the upper end of base is provided with fitting seat, it is domestic that fitting seat is provided with guiding, lead and be provided with expansion rubber sleeve between domestic and shell, the bottom of expansion rubber sleeve is provided with suction port, the outer wall of base is provided with inflation inlet, in base, be provided with the inflation road being communicated with expansion rubber sleeve suction port.
Improvement to technique scheme: be provided with large back-up ring between described expansion rubber sleeve and outer casing inner wall, be provided with little back-up ring between expansion rubber sleeve and guiding are domestic.
Further improvement to technique scheme: be threaded connection between the fitting seat of described base upper end and shell.
Beneficial effect:
Use a kind of blocking device detecting for Work piece sealing described in the utility model, by expansion cushion rubber inner chamber has been inflated to workpiece pipe sealing, reduced shutoff difficulty and the strict demand to the location of workpiece.This blocking device can adapt to automation completely and detect production line, has improved manufacturing efficiency, has reduced the demand to personnel, and simple in structure, easy to maintenance.
The utlity model has following advantage:
1, can effectively reduce the impact of the location of workpiece on plugging effect, be applicable to automation unattended;
What 2, this block head mechanism volume can design is less, is specially adapted to miniature workpiece; Overall weight is light, reduces labor strength;
3, applied widely, the serious forgiveness of the heat exchanger mouth of pipe is fine;
4, be applicable to the multiple testing environments such as malleation, negative pressure and water inspection.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The blocking device that the utility model as shown in Figure 1 detects for Work piece sealing, comprise shell 1, base 4, described shell 1 upper, lower end is respectively equipped with opening, in housing 1, be provided with in perforation, the endoporus of lower ending opening, base 4 is arranged in the opening of housing 1 lower end, the upper end of base 4 is provided with fitting seat 5, between fitting seat 5 and shell 1, be threaded connection, fitting seat 5 is provided with guiding domestic 7, lead domestic 7 and shell 1 between be provided with expansion rubber sleeve 2, the bottom of expansion rubber sleeve 2 is provided with suction port, the outer wall of base 4 is provided with inflation inlet B, in base 4, be provided with the inflation road being communicated with the suction port of expansion rubber sleeve 2, between described expansion rubber sleeve 2 and shell 1 inwall, be provided with large back-up ring 3, between expansion rubber sleeve 2 and guiding domestic 7, be provided with little back-up ring 6.
As shown in Figure 1, need to be detected the workpiece mouth of pipe 8 and go deep in blocking device, blocking device can arrange corresponding amount of floating according to the change in location of the mouth of pipe 8.When workpiece is first filled with pressurized air in expansion rubber sleeve 2 by B mouth before detection, expansion rubber sleeve 2 is out of shape and stings the tight mouth of pipe 8 under pressure, realizes sealing function.The rear detection facility sealing propertytest that communicated with inside workpiece by A mouth.After detection completes, the air in expansion rubber sleeve is discharged by B mouth, thereby unclamps workpiece.
