Abstract
A wheel-hub airtight testing machine comprises a machine tool body (9), a bracket (7), a fixing rack (4), a left-and-right transverse-moving guiding mechanism and an up-and-down lifting mechanism, wherein the machine tool body (9) is provided with the left-and-right transverse-moving guiding mechanism and the up-and-down lifting mechanism. The bracket (7) moves opposite to the up-and-down lifting mechanism along the left-and-right transverse-moving mechanism. The airtight testing machine is characterized in that a handwheel (14) is rotated to drive a bevel gear, a screw and the bracket to move in order to realize left and right moving of the wheel hub to complete a transverse airtight test. According to a structure of the testing machine provided by the utility model, an oil cylinder is mounted on the machine tool before and is disposed on a water storage tank of the machine tool now. A fixed plate for fixing the bracket mechanism is added between the bracket and the fixing rack. A problem of bad use rigid of the bracket because the bracket is directly arranged on the fixing rack before is solved. Problems that a locking screw loosens and left and right positioning of the bracket is inaccurate when the screw locks after left-and-right transverse moving of the bracket is in place are solved. The use stability of the machine tool is greatly improved, machine tool height is reduced and conveyance is very convenient.
Description
Technical field
The utility model belongs to automobile and motorcycle wheel hub air-tight test equipment carriage, can be used for horizontal gas tightness testing machine.
Background technology
Vertical or the horizontal workbench of the general employing of existing automotive hub gas tightness testing machine, promote the chuck clamping wheel hub by clamping cylinder and make this sealing, pressurize 30s under the air pressure of 〉=0.4MPa, bubble when leaking gas by aluminium wheel hub in the visual observations water is checked the gas leakage situation of aluminium wheel hub, and this is the air tight test method that domestic most producer selects.Original horizontal gas tightness airtight machine carriage mechanism adopts oil cylinder to be contained in lathe top drive carriage and moves up and down.Oil cylinder is contained in the lathe top, and lathe will be very high, and the transportation of lathe is installed and lathe stable bad.Put in place by screw rod transmission carriage transverse moving left and right rear locked with screw, process time is once the long lock screw inaccurate problem in location about carriage that gets loose that occurs.
Summary of the invention
Deficiency for mechanism's existence about the carriage in the setting-out mode of wheel hub airtight test machine, the purpose of this utility model is to provide a kind of wheel hub airtight test machine, that hoist cylinder is changed the position that is installed in the lathe, work supporting block about under the effect of hydraulic pressure, about operation wheel hub is carried out gas tightness testing machine, greatly improved the stability in use of lathe, reduce the height of lathe, be convenient to transportation.
The technical solution adopted in the utility model is: a kind of wheel hub airtight test machine, comprise lathe bed, carriage, fixed mount, transverse moving left and right guiding mechanism and oscilaltion mechanism, lathe bed is provided with transverse moving left and right guiding mechanism and oscilaltion mechanism, carriage is along relatively moving with transverse moving left and right mechanism and oscilaltion mechanism, and oscilaltion mechanism is comprised of hoist cylinder, lifting leading line rail and carriage installing plate; The transverse moving left and right guiding mechanism is comprised of handwheel, traversing guide pin bushing, traversing guide pillar and screw rod, hoist cylinder is fixed in the bed piece, the top of water butt upper sealing plate, the connecting rod of hoist cylinder links to each other by the carriage web joint with carriage, carriage is provided with test bucket upper table surface, test bucket upper table surface is placed with wheel hub, carriage is connected with fixed mount by line rail fixed head, it is characterized in that: described hand wheel rotating, band dynamic bevel gear, screw rod, carriage move, and realization wheel hub move left and right is finished horizontal airtight test.
The test bucket upper table surface that the connecting rod of described hoist cylinder promotes on the carriage web joint drive carriage rises and descends along the lifting leading line rail on the elevating mechanism, realizes that wheel hub moves up and down vertical airtight test.
Described traversing guide pin bushing is fixed on the carriage installing plate, traversing guide pillar and traversing guide pin bushing are slidingly matched, and are connected with bevel gear, bevel gear and screw rod engagement on the handwheel, bolt rotary, the traversing guide pin bushing and the carriage that drive on it move, the wheel hub move left and right of the test bucket upper table surface on it.
The utility model structure is installed in the lathe top with original oil cylinder, changes into the top of lathe water tank, and oil cylinder has been moved on to the bed piece the inside, is linked to each other with carriage by web joint, drives the carriage rise and fall.In the centre of carriage and fixed mount, increase the fixed head of a fixing carriage mechanism, change original carriage and be directly installed on and cause carriage to use rigidity bad on the fixed mount.Guidance mode changes the guide pillar guide sleeve structure into, has solved the carriage transverse moving left and right and has put in place rear lockedly with screw, the lock screw inaccurate problem in location that gets loose about carriage occurs.Greatly improved the stability in use of lathe, reduced the height of lathe, transported also very convenient.
