Abstract
The utility model relates to a welded seam vacuum testing-sealing device of a vehicle wheel felloe, belonging to the technical field of machinery manufacturing and testing. The vacuum testing-sealing device is mainly composed of a pressurized sealing cover, a vacuum sealing cover, a lower pressing machine and an upper propping machine. Both the pressurized sealing cover and the vacuum sealing cover are rectangular box-shaped bodies, the shapes of the opening rims are respectively inosculated with the shapes of the inner and outer walls at the periphery of the position of a wheel felloe welded seam, grooves are respectively opened at the opening positions of the pressurized sealing cover and the vacuum sealing cover, and sealing pipes are arranged in the grooves. When in use, the openings of the pressurized sealing cover and the vacuum sealing cover are respectively aimed at the inner wall and the outer wall at the periphery of the wheel felloe welded seam, and the lower pressing machine and the upper propping machine exert pressing force at the same time, so as to lead the pressurized sealing cover and the vacuum sealing cover to surround the wheel fellow welded seam; air is filled in the sealing pipes, a sealing environment is formed at position of the wheel felloe welded seam, and air is filled in the pressurized sealing cover, so as to lead a high-pressure zone to be formed at the inner part of the pressurized sealing cover; air is pumped from the vacuum sealing cover, so as to lead a vacuum zone to be formed at the inner part of the vacuum sealing cover; the air pressure in the vacuum sealing cover is tested by a vacuum leak detector, so as to judge whether gas leakage is incurred at the wheel felloe welded seam.
Description
Technical field:
The utility model belongs to the machine-building technical field of measurement and test, is a kind of wheel rim weld bond quality detection device.
Background technology:
Steel wheel rim is in (hereinafter to be referred as wheel rim) manufacture process, and the wheel rim weld bond is subjected to the stretching and the bending of different directions when roll extrusion, moulding.Weld bond is come to harm.Weld bond mass defect can cause wheel to reduce quality problems such as the slow pressure release of tire serviceable life.Must test weld bond for guaranteeing product quality.
The method of testing of existing equipment is shutoff wheel rim both sides, charge into the test pressurized air of authorised pressure to airtight wheel rim inner space, the wheel rim of the air of substituting the bad for the good is immersed in the water, in the test duration of regulation, the wheel rim weld bond place that the operator observes in the water has or not bubble to overflow, no bubble overflows and is specification product, otherwise is substandard product.Because of final detection result is artificially judged by the operator, so there is certain test error.
Summary of the invention:
The technical problems to be solved in the utility model is to disclose a kind of rim for automobile wheel weld bond vacuum test packoff, thereby can test the weld bond quality by gaseous tension exactly.
The scheme of the utility model technical solution problem is to adopt the pressurization lid, the vacuum seal lid, following press becomes rim for automobile wheel weld bond vacuum test packoff with last top mechanism, wherein pressurization lid and vacuum seal lid is rectangular box-like body, the shape of edge of opening respectively with wheel rim weld bond place around in, the outer wall shape matches, pressurization lid and vacuum seal cover gab place all have groove, sealed tube is housed in the groove, sealed tube one end has charging connector, pressurization lid and vacuum seal lid all have the tracheae with exterior, following press is contained in the top of pressurization lid, and last top machine is contained in vacuum seal lid below.During use, pressurization lid and vacuum seal cover gab are aimed at wheel rim weld bond inner and outer wall on every side respectively, following press and last top machine are exerted pressure to pressurization lid and vacuum seal lid simultaneously, make pressurization lid and vacuum seal lid surround the wheel rim weld bond, inflate in sealed tube by charging connector again, wheel rim weld bond place forms sealed environment, tracheae inflation in the pressurization lid by the pressurization lid, make the inner higher-pressure region that forms of pressurization lid, tracheae by the vacuum seal lid is bled in the vacuum seal lid, make the inner region of no pressure that forms of vacuum seal lid, wait for a period of time the back by the gaseous tension in the vacuum leak detection instrument test vacuum seal lid, judge whether the wheel rim weld bond has gas to leak.
Wherein sealed tube is to adopt resilient encapsulant to make, and can be rubber tube.
Because of can making the wheel rim temperature behind multi-step process such as welding, polishing, moulding in manufacture process, wheel rim raises.And wheel rim arrives behind multiple working procedure that the time of detecting station is inhomogeneous, and the wheel rim range of temperature is bigger, and temperature variation can influence measuring accuracy.
Scheme adopts vacuum state test down; Because of after the vacuum test chamber in the wheel rim outside is pumped into vacuum, the intracavity gas molecule is considerably less, and bigger wheel rim temperature variation is less to the test data influence, so adopt the method for testing judgement wheel rim weld bond quality of vacuum pressure difference
The concrete steps of test weld bond:
After reaching the specified vacuum value in the vacuum test chamber, close the vacuum pipe by-pass valve control, vacuum state enters the vacuum test stage after predefined short time pressure stability.Gather test data on the sensing receiver interval time in accordance with regulations by control system, record vacuum pressure Value Data P1 and P2 respectively;
Control system compares according to vacuum pressure difference DELTA P and the predefined standard vacuum pressure value difference of P1 and P2, judges whether wheel rim weld bond quality is qualified;
A; Δ P value is less than setting value; Product is qualified.
B; Δ P value is greater than setting value; Product is defective.
C; When Δ P value is very big; Product seriously leaks.
The product quality test result shows on machine tools control panel.Substandard product is sound, visual alarm prompting operation person handles defective workpiece.
Because after wheel rim was installed tire, the wheel rim two ends were in outside tires, so require very not strict to the welding quality at weld bond two ends.
The utility model has solved the wheel rim final detection result effectively artificially to be judged by the operator, has certain test error problem, simple to operate, dependable performance.
Description of drawings:
Fig. 1 is the utility model cut-open view;
Fig. 2 is pressurization lid synoptic diagram.
Embodiment:
The utility model is by pressurization lid 1, vacuum seal lid 2, following press 3 and last top machine 4 constitute, wherein pressurization lid 1 and vacuum seal lid 2 are rectangular box-like body, the shape of edge of opening respectively with wheel rim 9 weld bonds 10 places around in, the outer wall shape matches, pressurization lid 1 and vacuum seal are covered 2 opening parts and are all had groove 5, sealed tube 6 is housed in the groove 5, sealed tube 6 one ends have charging connector 7, pressurization lid 1 and vacuum seal lid 2 all have the tracheae 8 with exterior, following press 3 is contained in the top of pressurization lid 1, and last top machine 4 is contained in vacuum seal and covers 2 belows.Among Fig. 2 in order clearly to embody groove 5 and sealed tube 6, so be drawn as the edge of opening of pressurization lid 1 plane.
