Problems solved by technology
At present, most of the common spreaders are designed according to the shape characteristics of the cylinder block, relying on the pit or boss for clamping, so each type of cylinder block spreader is not universal, and the shape of the cylinder block is cast, with large dimensional deviation The hoisting of the shape structure will affect the stability and safety of hoisting
At the same time, the transfer process after clamping is also prone to slippage of the cylinder due to the jumping and tilting of the cable, causing serious production safety hazards
[0003] In the spreader (CN201485170U) disclosed in the spreader (CN201485170U) of the existing patented technology engine cylinder block fine milling top surface fine boring cylinder hole, the bolt is threaded connection installation, which affects work efficiency

The invention discloses a cylinder hole lifting appliance for machining an inclined oil hole of a cylinder body and a using method, the cylinder hole lifting appliance comprises a lifting appliance body, a lifting ring, a top plate and an anti-drop bolt, the lifting ring and the lifting appliance body are respectively distributed on the upper side and the lower side of the top plate, the lower end of the lifting ring is connected with the top plate, and the upper end of the lifting appliance body is connected with the top plate; the top plate is further provided with a penetrating hole penetrating through the upper side and the lower side of the top plate, the anti-disengaging plug pin is installed in the penetrating hole in a sliding mode, the anti-disengaging plug pin is of a big-end-up stepped column structure, and the lower end of the anti-disengaging plug pin is provided with an annular groove in the circumferential direction and a guide groove in the axial direction. The lower end of the guide groove is communicated with the annular groove; and a limiting piece is arranged on the top plate and is used for limiting the movement of the anti-falling bolt. The device has the advantages of simple structure, high working efficiency and the like.
Description
technical field [0001] The invention relates to the technical field of engine processing, in particular to a cylinder hole hanger for processing inclined oil holes of a cylinder block and a method of using the same. Background technique [0002] When machining the inclined oil hole on the main shaft hole of the cylinder block in a medium-sized engine, the parts need to be erected according to the direction of the main shaft hole, and then hoisted into the processing station for processing. The hoisting tool currently used is to screw the lifting ring screw into the threaded hole on the end face of the part, and then hoist it. It is troublesome to remove the lifting ring screws and is not suitable for mass production. Cylinder hole spreader is an auxiliary spreader for engine cylinder block processing. For example, when the engine cylinder block is machined on the horizontal processing equipment, the cylinder block needs to be hoisted with the side up. At present, most of ...
