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 air spring base water test unit, 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 are formed; The production run of base is through forming product after the machine work by foundry goods. in casting process; Be easy to generate trachoma, factor affecting product qualities such as pore, and then influence traffic safety.Therefore all bases must pass through pressure test and can entrucking use after qualified. 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, the air spring base has been carried out industrial analysis, must re-design the 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 air spring base water test unit is provided, satisfy the production needs and easy and simple to handle, production efficiency is high.
In order to solve above technical matters; Air spring base water test unit provided by the invention is characterized in that: have bracing frame, the support frame as described above upper fixed has table top; The table top top is provided with disk; Disk upper surface offers the groove that matches with air spring base circular arc boss, and groove is embedded with O-ring seal, and said table top is equipped with around equally distributed several of disk periphery has the screw rod hold down gag of briquetting; Said disk offers entery and delivery port, and the inlet tube and outlet tube that is connected with said entery and delivery port is respectively drawn from the table top below.
Further, said O-ring seal is the O RunddichtringO.
Further, said table top is equipped with around equally distributed 6 the screw rod hold down gags with briquetting of disk periphery.
Beneficial effect of the present invention is following: the present invention is skillfully constructed, and is simple in structure, utilizes this water test unit can find the defective that the air spring base produces timely and accurately in casting and machining process, guarantees product quality; And easy to use, improved efficient, satisfy passenger vehicle in enormous quantities and produced needs.
Description of drawings
Below in conjunction with accompanying drawing the present invention is further described.
Fig. 1 is an air spring understructure synoptic diagram.
Fig. 2 is this air spring base water test unit structural representation.
Embodiment
The air spring base water test unit of present embodiment; As shown in Figure 2, have bracing frame 1, bracing frame 1 upper fixed has table top 2; Table top 2 tops are provided with disk 3; Disk 3 upper surfaces offer the groove 4 that matches with air spring base circular arc boss, and groove 4 is embedded with O RunddichtringO (being signal among the figure), and table top 2 is equipped with around disk 3 peripheral equally distributed 6 screw rod hold down gags 6 with briquetting 5; Disk 3 offers entery and delivery port (meaning not shown in the figures), and the water inlet pipe 7 that is connected with said entery and delivery port respectively, rising pipe 8 are drawn from table top 2 belows.
Except that the foregoing description, 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.
