Abstract
The utility model discloses a pressure testing device for a thermostat housing, comprising a handle, an annular seal cover matched to the cooling water inlet hole of the thermostat housing, a back-up ring arranged between the handle and the annular seal cover, and a pull rod hinged to the handle after passing through the annular seal cover and the back-up ring, wherein the pull rod is provided with a pressure head for applying a pressure to the annular seal cover, the surface of the handle contacted with the back-up ring is an eccentric surface with respect to an articulated shaft. According to the pressure testing device for a thermostat housing, the annular seal cover is equipped into the water inlet hole of the thermostat housing, and the handle is moved to shorten the distance between the pressure head of the pull rod and the back-up ring, such that the pressure head can extrude the annular seal cover to produce a radial deformation, thus sealing the water inlet hole of the thermostat housing, therefore the sealing operation is convenient and fast, greatly improving the sealing test operation of the thermostat housing; and the sealing operation is realized without moving the thermostat housing, greatly saving the muscle power of an operator, and further raising the operation efficiency.
Description
Technical field
The utility model relates to a kind of air pressure proving installation, particularly a kind of device to thermostat housing measuring air pressure.
Background technology
Thermostat is the cooling device on the engine, is provided with cooling water cavity in the thermostat housing, and the inside has chilled water to pass through.The thermostat housing requires that leakage defect can not be arranged, so the sealing of the cooling water cavity of thermostat housing has very big influence to the performance of thermostat.Therefore in the process of making the thermostat housing, must carry out sealing to thermostat housing cooling water cavity and detect.
When detecting, the sealing of thermostat housing of the prior art adopts the pressure testing detection mode; Promptly the inlet opening of thermostat cooling water cavity is stopped up with packoff with packoff; Feed pressurized air through air compressor to the water side of thermostat cooling water cavity again, judge the sealing of thermostat cooling water cavity through the pressure in the test thermostat housing cooling water cavity.
The packoff of prior art comprises that the platen that is provided with a rubber seal, promotes the clamp body that screw mandrel and that platen moves cooperates with wire rod thread.During each pressure testing, need the thermostat housing be brought up to clamp body, after pressure testing is accomplished, need again the thermostat housing is moved down clamp body; Because thermostat housing heavier (100kg) is moved thermostat and is wanted labor time and muscle power; The water inlet of platen and thermostat housing is aligned, debug cumbersome; Therefore cause thermostat housing seal property testing efficient extremely low, the pressure testing capacity utilization is low, and operator's labour intensity is big, and causes the thermostat housing whole process of production time long, and throughput rate is low.
Therefore need the pressure test of thermostat housing of the prior art be improved with packoff, to improve sealing test efficient.
The utility model content
In view of this, the purpose of the utility model provides a kind of thermostat housing pressure testing device, and it can solve the inefficient problem of thermostat housing seal property testing.
The utility model thermostat housing pressure testing device; Comprise handle, advance ring-shaped sealing sleeve that the hole cooperates with thermostat housing chilled water, be arranged at the back-up ring between handle and the ring-shaped sealing sleeve and pass ring-shaped sealing sleeve, back-up ring successively after the pull bar hinged with handle; Said pull bar is provided with the pressure head of exerting pressure to ring-shaped sealing sleeve, and the face that handle contacts with back-up ring is eccentric face with respect to jointed shaft.
Further, be provided with sealing gasket between said pressure head and the ring-shaped sealing sleeve;
Further, be provided with packing ring between said pressure head and the sealing gasket;
Further; Said handle is a direct rod shape; The face that handle contacted with back-up ring when handle was parallel with pull bar is the plane I, and the face that handle contacted with back-up ring when handle was vertical with pull bar is a Planar Mechanism, and the plane I arrives the distance in jointed shaft axle center less than Planar Mechanism to the distance in jointed shaft axle center.
The beneficial effect of the utility model: the utility model thermostat housing pressure testing device; With the ring-shaped sealing sleeve thermostat housing inlet opening of packing into, to move handle and make the reduced distances between pull bar pressure head and the back-up ring, pressure head can push ring-shaped sealing sleeve makes it produce radial deformation; Thereby sealing thermostat housing inlet opening; Sealing operation is convenient and swift, raising thermostat housing seal property testing operation that can be very big, and sealing operation need not be moved the thermostat housing; Saving operator muscle power that can be very big can further improve operating efficiency.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Fig. 1 is the utility model thermostat housing pressure testing device one-piece construction cut-open view;
Fig. 2 is the utility model thermostat housing pressure testing device user mode synoptic diagram.
Embodiment
Fig. 1 is the utility model thermostat housing pressure testing device one-piece construction cut-open view; Fig. 2 is the utility model thermostat housing pressure testing device user mode synoptic diagram.
As shown in the figure; Present embodiment thermostat housing pressure testing device; Comprise handle 1, advance ring-shaped sealing sleeve 2 that the hole cooperates, be arranged at the back-up ring 3 between handle 1 and the ring-shaped sealing sleeve 2 and pass the hinged pull bar 4 of ring-shaped sealing sleeve 2, back-up ring 3 backs and handle 1 successively with thermostat housing chilled water; Said pull bar 4 is provided with the pressure head 4a that exerts pressure to ring-shaped sealing sleeve 2, and the face that handle 1 contacts with back-up ring 3 is eccentric face with respect to jointed shaft 5.When carrying out thermostat housing seal property testing; With the ring-shaped sealing sleeve 2 thermostat housing inlet opening of packing into, move handle 1 and make the reduced distances between pull bar pressure head and the back-up ring, pressure head 4a can push ring-shaped sealing sleeve 2 makes it produce radial deformation; Thereby sealing thermostat housing inlet opening; Sealing operation is convenient and swift, raising thermostat housing seal property testing operation that can be very big, and sealing operation need not be moved the thermostat housing; Saving operator muscle power that can be very big can further improve operating efficiency.
As improvement to this embodiment, be provided with sealing gasket 6 between said pressure head 4a and the ring-shaped sealing sleeve 2, sealing gasket 6 is set can prevents that gas from from the clearance leakage between pull bar 4 and the ring-shaped sealing sleeve 2, can improve the measurement accuracy.
As improvement to this embodiment, be provided with packing ring 7 between said pressure head 4a and the sealing gasket 5, packing ring 7 can make ring-shaped sealing sleeve 2 each several parts stressed more even, thereby makes the each several part distortion of ring-shaped sealing sleeve 2 more even, improves sealing effectiveness.
As improvement to this embodiment; Said handle 1 is a direct rod shape; The face that handle 1 contacted with back-up ring 3 when handle 1 and pull bar 4 were parallel is the plane I; The face that handle 1 contacted with back-up ring 3 when handle 1 and pull bar 4 were vertical is a Planar Mechanism, the plane I to the distance in jointed shaft 5 axle center less than the distance of Planar Mechanism to jointed shaft 5 axle center.Surface of contact is the plane, and after handle 1 rotate in place, its station keeping was good, can make more convenient operation.
