Abstract
The utility model provides a simple clamp for oxidizing the top of an aluminum-alloy piston and an anode of a ring slot. The simple clamp comprises a sealing drum, a conductive plate, a connecting screw, a pin and a butterfly nut, wherein an aluminum-alloy piston locating hole is formed inside the sealing drum; a seal ring is arranged at the lower end of the aluminum-alloy piston locating hole; the conductive plate is arranged at the upper end of the aluminum-alloy piston locating hole; a hook is arranged at the upper end of the connecting screw; the connecting screw penetrates through the conductive plate; the pin is connected with the lower end of the connecting screw; and the butterfly nut is spirally arranged on the connecting screw, and the butterfly nut is pressed at the upper end surface of the conductive plate. The simple clamp is simple in structure, convenient to operate, suitable for trail productions and small-scale product production, and low in manufacturing cost, and can replace a special tooling for oxidization.
Description
Technical field
The utility model relates to a kind of aluminium-alloy piston top and the anodised simple and easy anchor clamps of annular groove.
Background technology
Discharging for the hydrocarbon polymer that reduces engine, and reduction engine consumption, increasing design is optimized improvement to piston structure, particularly improve the position of first annular groove, namely reduce top land firepower bank height, increase the piston ring cause and the adhesion problems of piston ring groove but bring like this because of top pressure.In the situation of engine with higher specified property parameter and low overhead height, move; the temperature of first annular groove will be greater than 250 ℃; this temperature can cause the trickle weldering company of generation between annular groove side and the first ring; especially the easier generation of new engine is that first annular groove to aluminium-alloy piston carries out anodic oxidation and solve best protection measure that trickle weldering connects.In addition, in the first annular groove, carry out anodic oxidation and can improve wear resistance and protective, also improved the thermal load of annular groove simultaneously.
To the anodic oxidation of aluminium-alloy piston first annular groove, from product structure design dual mode is arranged, the first comprise the first annular groove and on the top land surface carry out anodic oxidation, it two is only the first annular groove to be carried out anodic oxidation.Which kind of mode no matter, in production in enormous quantities in order to ensure quality product, must adopt special tooling and matching special equipment, special tooling and matching special equipment manufacturing cost are high, wherein the second is higher than the first cost, therefore, most first kind of way that adopt during product design, namely to aluminium-alloy piston first annular groove and on the top land surface carry out anodic oxidation.For trial production and small serial production, if adopt special tooling and supporting specific equipment thereof, its cost is high, and is obviously not too suitable.
Summary of the invention
The utility model is high for aluminium-alloy piston anodic oxidation special tooling and support equipment manufacturing cost, and the problem of improper small serial production provides a kind of aluminium-alloy piston top and the simple and easy anchor clamps of annular groove anodic oxidation.
A kind of aluminium-alloy piston top and the simple and easy anchor clamps of annular groove anodic oxidation, comprise sealing bore, conducting plates, connecting screw rod, pin and wing nut, it is characterized in that: be provided with the aluminium-alloy piston pilot hole in the sealing bore, the lower end of aluminium-alloy piston pilot hole is provided with sealing-ring, conducting plates is contained in aluminium-alloy piston pilot hole upper end, the upper end of connecting screw rod is provided with hook, connecting screw rod passes conducting plates, pin is connected to the connecting screw rod lower end, the wing nut spinning is on connecting screw rod, and the wing nut top is pressed in the conducting plates upper surface.
Beneficial effect: during use, aluminium-alloy piston is contained in the aluminium-alloy piston pilot hole, only expose top and annular groove, sealing bore and sealing-ring are with piston packing, pin inserts the pin-and-hole of aluminium-alloy piston, pin is connected with connecting screw rod again, and pin, wing nut, connecting screw rod and conducting plates are fixedly clamped aluminium-alloy piston together; Then aluminium-alloy piston is placed between the negative electrode of along the circumferential direction arranging, place oxidation trough, can carry out oxidation.Of the present utility model simple in structure, easy to operate, be fit to trial production and small serial production, substituted the oxidation special tooling, low cost of manufacture.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
A kind of aluminium-alloy piston top as shown in Figure 1 and the simple and easy anchor clamps of annular groove anodic oxidation, comprise sealing bore 2, conducting plates 4, connecting screw rod 6, pin 3 and wing nut 5, be provided with the aluminium-alloy piston pilot hole in the sealing bore 2, the lower end of aluminium-alloy piston pilot hole is provided with sealing-ring 1, conducting plates 4 is contained in aluminium-alloy piston pilot hole upper end, the upper end of connecting screw rod 6 is provided with hook 7, connecting screw rod 6 passes conducting plates 4, pin 3 is connected to connecting screw rod 6 lower ends, wing nut 5 spinnings are on connecting screw rod, and wing nut 5 tops are pressed in conducting plates 4 upper surfaces.
Principle of work: during use, aluminium-alloy piston 8 is contained in the aluminium-alloy piston pilot hole, only expose top and annular groove, sealing bore and sealing-ring are with piston packing, pin inserts the pin-and-hole of aluminium-alloy piston, pin is connected with connecting screw rod again, and pin, wing nut, connecting screw rod and conducting plates are fixedly clamped aluminium-alloy piston together; Then aluminium-alloy piston is placed between the negative electrode of along the circumferential direction arranging, place oxidation trough, can carry out oxidation.
