Abstract
The invention discloses a hydrostatic test device for air spring bases, which is provided with a support frame, wherein a table is fixed above the support frame, and a disc is arranged above the table; the upper surface of the disc is provided with a groove which is matched with an arc boss of an air spring base, and a seal ring is embedded into the groove; the table is provided with a plurality of screw compression devices which are uniformly arranged around the periphery of the disc and respectively provided with a pressing block; the disc is provided with a water inlet and a water outlet; and a water inlet pipe and a water outlet pipe which are respectively connected with the water inlet and the water outlet are extracted from the underside of the table. The hydrostatic test device disclosed by the invention is skillfully constructed and simple in structure; by using the hydrostatic test device, the defects of an air spring base generated in the processes of casting and machining can be found in time accurately, thereby ensuring the product quality; and the hydrostatic test device is easy to use, improves the efficiency, and satisfies the needs of mass production of passenger-cars.
Description
Technical field
The present invention relates to a kind of Hydrotest device of air spring base, belong to the technical field of rail truck manufacturing process.
Background technology
Air spring base (seeing accompanying drawing 1) is the vitals during double decker coach and generator car bogie form, the production run of base is by foundry goods, after machine work, to be formed product. in casting process, easily produce trachoma, the factors such as pore affect product quality, and then affect traffic safety.Therefore all bases must can be used after pressure test is qualified in entrucking. and original air pressure test is because of the little (6kgf/cm of pressure
2) (new standard must be hydraulic pressure test 16kgf/cm not meet new technological standards
2) requirement, can not meet the needs of production.For addressing the above problem, air spring base has been carried out to industrial analysis, must re-design base hydraulic pressure test fixture.The present invention has opened up a new way for addressing the above problem.
Summary of the invention
Technical matters to be solved by this invention is, overcomes the above-mentioned shortcoming of prior art, and a kind of Hydrotest device of air spring base is provided, meet need of production and easy and simple to handle, production efficiency is high.
In order to solve above technical matters, Hydrotest device of air spring base provided by the invention, it is characterized in that: there is bracing frame, support frame as described above top is fixed with table top, table top top is provided with disk, disk upper surface offers the groove matching with air spring base circular arc boss, groove is embedded with O-ring seal, described table top is provided with around the equally distributed several screw compressing apparatus with briquetting of disk periphery, described disk offers entery and delivery port, and the inlet tube and outlet tube being connected with described entery and delivery port is respectively drawn from table top below.
Further, described O-ring seal is O RunddichtringO.
Further, described table top is provided with around equally distributed 6 screw compressing apparatus with briquetting of disk periphery.
Beneficial effect of the present invention is as follows: the present invention is skillfully constructed, simple in structure, utilizes this water test unit can find timely and accurately the defect that air spring base produces in casting and machining process, guarantees product quality; And easy to use, improved efficiency, met passenger vehicle need of production in enormous quantities.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Fig. 1 is air spring understructure schematic diagram.
Fig. 2 is this Hydrotest device of air spring base structural representation.
Embodiment
The Hydrotest device of air spring base of the present embodiment, as shown in Figure 2, there is bracing frame 1, bracing frame 1 top is fixed with table top 2, table top 2 tops are provided with disk 3, disk 3 upper surfaces offer the groove 4 matching with air spring base circular arc boss, groove 4 is embedded with O RunddichtringO (being signal in figure), table top 2 is provided with around peripheral equally distributed 6 screw compressing apparatus 6 with briquetting 5 of disk 3, disk 3 offer into, water delivering orifice (meaning not shown in the figures), enter with described respectively, the water inlet pipe 7 that water delivering orifice connects, rising pipe 8 is drawn from table top 2 belows.
In addition to the implementation, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
