Abstract
A repaired damaged engine cylinder belongs to a burning engine cylinder, includes a cylinder body and a working cylinder sleeve and is characterized in that a fixed cylinder sleeve is laid between the cylinder body and the working cylinder sleeve; the fixed cylinder sleeve and the cylinder body are interference fitted; the working cylinder sleeve is arranged in the fixed cylinder sleeve. The utility model totally solves the problems that broken cylinders leak and fail to work and has the advantages of simple structure and convenience in use; the fixed cylinder sleeve only needs to be pressed in the diameter of the cylinder; the repairing cost of the cylinder is greatly reduced; the utility model can repair single-cylinder-diameter, double-cylinder-diameter, 3-cylinder, 4-cylinder, 5-cylinder, 6-cylinder and multi-cylinder products.
Description
Technical field the utility model belongs to the combustion engine cylinder, relates generally to cylinder structure.
The background technology engine cylinder for various reasons, damage such as can produce fragmentation, leak; Dual mode is arranged at present, the one, engine is scrapped, and cost is higher, and waste is serious; The 2nd, engine broken, that leak is repaired; To repairing general employing welding or bonding method.During welding, no matter be gas welding, electric welding, because of the cylinder aperture restriction, soldering appliance enters difficulty, enters reluctantly, also influences welding quality, further the machining difficulty; Adopt bonding way, the one, bonding agent is difficult to reach the intensity and the precision of cylinder work, and the 2nd, the immersion that can not effectively resist the high temperature and the long-time water of cylinder work after bonding does not reach the purpose of repairing cylinder.Chinese patent ZL94214392.2 discloses a kind of mode to repairing after the minicar engine cylinder sleeve wearing and tearing, and it is to repair at D62～70mm cylinder on the one hand, on the other hand its also be not suitable for the cylinder fragmentation, the reparation after leaking.
The summary of the invention the purpose of this utility model provides a kind of to broken, the engine cylinder reparation of leaking, and simple in structure, practical, and cost is low, the damaged engine cylinder of effective reparation.
The utility model comprises cylinder body and work cylinder sleeve, it is characterized in that embedding fixedly cylinder sleeve between cylinder body and the work cylinder sleeve, and fixing cylinder sleeve and cylinder body employing interference fit, working cylinder is placed on fixedly in the cylinder sleeve.
Fixedly outer wall of cylinder jachet of the present utility model is straight tubular, also can be stairstepping.Fixedly the value of interference fit of cylinder sleeve and cylinder body is 0.08～0.15mm.Fixedly the size of cylinder sleeve is greater than the internal diameter size of cylinder body.
Because the utility model embeds fixedly cylinder sleeve between cylinder body and work cylinder sleeve, fixing cylinder sleeve and cylinder body employing interference fit has solved thoroughly that broken cylinder body leaks, inoperable problem; And simple in structure, easy to use, the stationary cylinder cover is pressed into cylinder diameter gets final product, greatly reduce the cost that cylinder body is repaired.The utility model can be repaired single cylinder footpath, twin-tub footpath, 3 cylinders, 4 cylinders, 5 cylinders, 6 cylinders and multi-cylinder.With the motor cylinder block is example, 9400 yuan/platform of comings cylinder body price, and rehabilitation cost is 10%; Compact car cylinder body 6102 is about 3000 yuan/platform, and its rehabilitation cost is 20%; The minicar cylinder body is about 500 yuan/platform, and its rehabilitation cost is 6%.
The utility model is described in further detail below in conjunction with accompanying drawing for description of drawings:
Fig. 1 is the shape schematic diagram of damaged cylinder body;
Fig. 2 is the fixedly structural representation of cylinder sleeve of the utility model stairstepping;
Fig. 3 is the utility model structural representation.
The specific embodiment is at first carried out boring with the cylinder diameter of the damaged cylinder body 1 of Fig. 1, then fixedly cylinder sleeve shown in Figure 22 usefulness press are pressed in the cylinder diameter of cylinder body 1, the value of its interference fit is 0.08～0.15mm, again with cylinder boring machine to after fixedly the endoporus of cylinder sleeve 2 carries out boring, work cylinder sleeve 3 is inserted in the endoporus of fixing cylinder sleeve 2, can be with the cylinder body cylinder diameter reparation (structure as shown in Figure 3) of breakage.
Fixedly the magnitude of interference between cylinder sleeve and the cylinder body can be reserved according to the thickness and the intensity of cylinder body, and its interference can be stayed fixedly cylinder sleeve external diameter, also can stay on the internal diameter of cylinder body.According to the damaged situation of cylinder body cylinder diameter, tubular or step-like fixedly cylinder sleeve are adopted in decision.
Claims (3)
1, a kind of damaged engine cylinder of reparation comprises cylinder body and work cylinder sleeve, it is characterized in that embedding fixedly cylinder sleeve between cylinder body and the work cylinder sleeve, and fixing cylinder sleeve and cylinder body employing interference fit, working cylinder is placed on fixedly in the cylinder sleeve.
2, the damaged engine cylinder of reparation according to claim 1 is characterized in that fixedly the outer wall of cylinder sleeve is straight tubular, also can be stairstepping.
