Description
Technical field
The present invention relates to a kind of big end of engine link rise disconnected device and using method of making.
Background technology
At present, the connecting rod breaking process that rises is the Material Used fracture theory, a kind of technology that connecting rod cap is separated from the gonnecting rod body fracture.Adopt this technology can save many procedures (milling of no connecting rod faying face, grinding and broaching etc.) in the conventional linkage processing, make Machining of Connecting Rod become simpler.
Compare with traditional Machining of Connecting Rod method, adopt the connecting rod breaking process that rises to save machine tool investment 25%, reduce cutter expense 35%, save the energy 40% etc.Therefore greatly reduce the processing charges of connecting rod.
The principle of breaking process of rising is a prefabricated V-type groove on the crank pin end pore split surface, applies a power that struts at groove then.Concentrate owing to produced stress, thereby gonnecting rod body and connecting rod cap are strutted at groove.This technology all has very high requirement to the material of connecting rod and the dimensional accuracy of groove.In the disconnected process that rises, if connecting rod material performance and groove size precision do not reach requirement, be easy to so cause that connecting rod is monolateral tears, the section knockdown appears, fall problems such as slag is serious.
At present, enterprise produces the kind model variation of engine, and it is many that the engine link specifications and models become, and the used connecting rod of the enterprise disconnected device that rises can not realize that a table apparatus satisfies the rise demand of disconnected processing of many kinds connecting rod, and processing cost is higher.
Chinese patent CN200410071275.0 discloses the method and apparatus that is used to make connecting rod cracking, by preload mechanism preload imposed on the wedge that is pressed between the pair of separated device fast on, so that separator is pressed against be defined on the inner surface in the connector hole in the bigger end of connecting rod, when separator pressed the inner surface of nipple orifice, the portable plate that is furnished with weight above making fell and bumps against with the flange that is being connected shaft end.Axle is pulled down, so that apply impact load along the direction that is pressed into voussoir to the voussoir that is connected with axle, thereby makes bigger end be broken into cap body and bar.Its weak point is the disconnected connecting rod of processing different size of can not realizing rising.
Summary of the invention
The device and the using method that the purpose of this invention is to provide a kind of disconnected processing different size connecting rod that can rise.
The technical solution adopted for the present invention to solve the technical problems is: a kind of connecting rod disconnected device that rises, comprise soleplate, be fixedly installed on the plate of deciding on the soleplate, be arranged on the slide plate in the slide rail on the soleplate, be used to locate the cracking seat with the big end of cracking connecting-rod, described cracking seat front portion is fixedly installed on slide plate, and described cracking seat rear portion is fixedly installed on decides on the plate, be pressed into the cracking wedge of cracking seat during cracking, above the cracking wedge, be provided with hydraulic jack; The inboard vertical slide rail direction of described connecting rod tip has the first stress groove and the second stress groove.Also comprise removable adjusting location-plate, described location-plate is fixedly installed on the guide groove of slide plate by set bolt; Be set with alignment pin on the described location-plate, be provided with small washer between described alignment pin and the wrist-pin end of connecting rod inboard; Between described cracking seat and the connecting rod tip inboard separative large washer is set, described large washer is divided into the anterior and large washer rear portion of large washer.
Cause monolateral tearing for connecting rod in the disconnected process that prevents to rise produces rotation, describedly decide plate and be provided with fixed block, described fixed block will hold out against first push rod and second push rod of connecting rod tip and fix.
In order to make connecting rod tip plane of disruption position accurate, described stress groove is the V-type groove.
In order to make the downward pressure of hydraulic jack better change into the tension force of cracking seat horizontal direction, described cracking seat front portion has and the suitable inclined-plane of cracking wedge.
Further, the rise using method of disconnected device of connecting rod, it is disconnected that connecting rod tip is risen, and may further comprise the steps:
Step 1: will need fracture position to offer the stress groove on the connecting rod tip;
Step 2: regulate location-plate, the distance between alignment pin and the cracking seat front portion is complementary with connecting rod two stomidiums that will process, select and suitable small washer and the large washer of connecting rod two stomidiums, be enclosed within respectively on alignment pin and the cracking seat;
Step 3: wrist-pin hole is inserted on the alignment pin that is with small washer, and crank bore is inserted on the cracking seat that is with large washer, makes the alignment of large washer opening and stress groove;
Step 4: rotate first push rod and second push rod holds out against the connecting rod tip balance;
Step 5: the cracking wedge is inserted in the cracking seat, by hydraulic jack the cracking wedge is exerted pressure, disconnected connecting rod tip rises.
Beneficial effect of the present invention: can regulate distance between alignment pin and the cracking seat because described slide plate is provided with location-plate, and be provided with small washer and satisfy different tie rod holes, make it can process the connecting rod of different size with the large washer that separates.Owing to be provided with push rod and stress groove, produce in the disconnected process that effectively prevents to rise that connecting rod tip is monolateral tears the section inclination defect.Mechanism is simple, low cost of manufacture.
Below with reference to drawings and Examples, the present invention is carried out comparatively detailed explanation.
