Special cleaning pump cover oil duct machine frame
Technical field
The utility model relates to machine components manufacture field, refers in particular to Special cleaning pump cover oil duct machine frame.
Background technology
Automotive transmission pump cover endoporus oil circuit has higher dimensional accuracy, and surface roughness.Employing highly pressurised liquid cleans, and the burr produced after utilizing its instant impact to remove processing and overlap, can reach the object of cleaning simultaneously.Adopt the burr removing method of workpiece movable formula, because its cost is low, its shortcoming is that the fitness of nozzle and valve body is undesirable, special procures a kind of stand of design, improves the fitness of nozzle and valve body.
Utility model content
For overcoming the above problems, the utility model provides a kind of structure simple, is applicable to Special cleaning pump cover oil duct machine frame.
Special cleaning pump cover oil duct machine frame, comprise gear fuel tank, be arranged on gear fuel tank on base plate and door, gear fuel tank top be provided with cylinder assembly, described cylinder assembly is connected with door, cylinder assembly bottom overlap have sealing pressure head; Be fixed with positioning seat in the middle of described base plate, positioning seat is provided with the centre of base plate the inlet opening be communicated with highly pressurised liquid, and positioning seat is provided with seal cover, and positioning seat periphery is provided with back-shaped groove, has fluid hole in back-shaped groove.
Preferably, described seal cover has seal groove.
Preferably, described cylinder assembly is connected with door L shape fixed head.
Preferably, cylinder assembly comprises cylinder and cylinder linkage board.
Preferably, seal groove is provided with between positioning seat and base plate.
Special cleaning pump cover oil duct machine frame described in the utility model, the inlet opening of highly pressurised liquid in the middle part of base plate, pump housing internal control is entered by positioning seat, the other end of pump is sealed by pressure head, and the liquid of certain pressure flows out from pump housing hole, washes away pump housing endoporus, deburring, and cleaning inner chamber, the liquid after outflow, in bottom plate groove, is flowed out by base plate liquid outlet.
The beneficial effects of the utility model are: the utility model is according to the independent Design Orientation seat of product, seal cover, and replacing positioning seat, seal cover can adapt to the product of different model.Nozzle and substrate tubes joint connect, and do not have fitness problem.Pneumatic cylinder drives door to move together with pressure head, namely adds thrust, has shut again door, be convenient for changing part.

Detailed description of the invention
1-6 by reference to the accompanying drawings, Special cleaning pump cover oil duct machine frame, comprises fixed head 1, cylinder and cylinder gusset piece 2, nut 3, pressure head 4, seal cover 5, base plate 6, back leakage connection 7, positioning seat 8, pipe joint 9, gear fuel tank 10, door 11, slotted pan head screw 12.
Described part is arranged between positioning seat 8, seal cover 5, and they and feature contacts part are provided with sealing ring; Cylinder 2 is connected with door 11 L shape fixed head 1; L shape fixed head 1, porose in the middle of one end, by nut 3 and pressure head 4, be pressed in cylinder lever, the other end, beat multiple hole, be fixed on door by slotted pan head screw 12; Positioning seat 8, seal cover 5 design according to accessory size; Have boss, back-shaped groove in the middle of base plate 6, have fluid hole in back-shaped groove, boss bottom has inlet opening; Seal cover 5 and pumping holes contact portion have long boss.
Implementation process prescription is as follows:
Part is arranged on positioning seat 8, covers seal cover 5; Cylinder 2 lever band dynamic head 4 and door 11 move downward, and close visit 11 and compressing component; The inlet opening of highly pressurised liquid in the middle part of base plate 6, pump housing internal control is entered by positioning seat 8, the other end of pump is sealed by seal cover 5, the liquid of certain pressure flows out from pump housing hole, wash away pump housing endoporus, deburring, and clean inner chamber, liquid after outflow, in base plate 6 groove, is flowed out by base plate 6 liquid outlet.After cleaning, cylinder 2 lever band dynamic head 4 and door 11 move upward, and open door 11 and unclamp part, taking off seal cover 5, change other part of same model, cleaning.
When cleaning the pump cover of other model, change positioning seat 8, seal cover 4.
