Description
Technical Field
The invention relates to a press fitting and edge riveting technology for a crank oil thrower, in particular to a press fitting and edge riveting tool for the crank oil thrower.
Background
In the operation process of the crankcase, iron chips and other particles formed at the corners of parts such as a crankshaft, a gear and the like in the machining process can fall off from the machine body and flow in the crankcase along with lubricating oil. In order to prevent iron chips flowing in the crankcase from damaging parts such as the crankshaft, the gear and the like, an oil thrower is arranged on the crank disc part. When the crank rotates at a high speed, lubricating oil can be thrown into a gap between the oil thrower and the end face of the crank disc part, so that scrap iron particles mixed in the lubricating oil are gathered, and the damage to parts such as a crankshaft, a gear and the like is avoided. The oil thrower is a circular ring formed by punching a metal sheet, a V-shaped groove (see figure 1, in the figure, a is the oil thrower and b is the V-shaped groove) for pressing the oil thrower on the crank disc part is arranged at the outer edge of the circular ring, and a rectangular groove for pressing the oil thrower is correspondingly arranged on the end face of the crank disc part. During press fitting, the crank is fixed on the working table, the oil thrower is placed on the end face of the crank disc part, and the V-shaped groove of the oil thrower is aligned to the rectangular groove of the crank disc part. And placing a press punch on the oil thrower, wherein the edge of the press punch is provided with a V-shaped groove tapered step which is pressed against the oil thrower. And (3) applying pressure on the stamping to enable the stamping tapered step to abut against the V-shaped groove of the oil thrower to enter the rectangular groove on the end face of the crank disc part (see the attached drawings 2 and 3, wherein a is the oil thrower, b is the V-shaped groove, c is the crank, and d is the rectangular groove), so that the oil thrower is pressed on the end face of the crank disc part.
In order to ensure that the oil thrower plate does not fall off due to high-speed rotation of the crank during operation of the crankcase. The edge riveting is usually carried out after the oil thrower is pressed. Namely, the outer edge of the rectangular groove with the oil thrower on the edge of the crank disc part is rolled towards the center of the crank by adopting the idler wheels, so that the outer edge of the rectangular groove on the edge of the crank disc part is bent inwards, and the oil thrower is riveted in the rectangular groove on the edge of the crank disc part.
In the prior art, the process of press mounting and edge riveting of the crank oil thrower is completed by two working procedures, namely, the oil thrower is pressed on the end face of a crank, which is afraid of resistance, on an oil press; and clamping the crank with the oil thrower disc pressed on a lathe turntable, and installing rollers on a lathe tool frame, so as to rivet the outer edge of the rectangular groove at the edge of the crank disc part. Because the V-shaped groove of the oil thrower and the rectangular groove at the edge of the crank disc part have machining errors, and the press-fitting errors also exist during press-fitting, the oil thrower falls off from the rectangular groove of the crank when part of the crank is subjected to edge riveting, or the oil thrower is fixed and not fastened during rivet-fitting, so that the oil thrower falls off when the crank rotates at a high speed.
Obviously, the press fitting and edge riveting process of the crank oil thrower in the prior art has the problem that the oil thrower possibly falls off from a rectangular groove of a crank when the edge is riveted, or the rivet fitting is fixed and is not fastened, so that the oil thrower falls off and the like.
