When the turning lathe ejector pin is used for turning an outer circle of the movement bolt, the tail part of the movement bolt is jacked, and the surface of the movement bolt is free from pressure loss.
Description
Technical field
The present invention relates to motion bolt cylindrical Vehicle Processing technical field in marine diesel cylinder, is specifically a kind of lathe thimble of using motion bolt in diesel engine cylinder for factory ship.
Background technology
At present, there is a kind of tonnage to reach the marine low speed diesel engine of 1850t, in the cylinder of this diesel engine, for connecting the connector of piston and piston rod, generally adopt high-quality special steel alloy to be made, integral body is cylindrical shape, two ends are provided with the screw thread that connects use, this motion connector also moves with piston, piston rod when playing connection function, therefore be commonly called as in industry as motion bolt.
Because the internal diameter of this motion bolt is mostly 100mm left and right, have even to have reached 110mm big, and that length has is 2.7～3m, the length that has even reached 10m having, as utilize the lathe of prior art motion bolt to be carried out to the Vehicle Processing of cylindrical, for holding out against the conventional thimble of motion bolt tail, because size is too little, cannot normally use, the ad hoc structure of having counted a kind of similar chuck of inventor clamps motion bolt tail for this reason, but this chuck structure more complicated, parts are more, the time of expending when clamping is longer, need assemble each parts, use operates and is not very convenient, and chuck clamps great efforts, to motion bolt surface, can cause certain crushing.
Summary of the invention
Technical problem to be solved by this invention is that a kind of motion bolt tail and lathe thimble with motion bolt in diesel engine cylinder for factory ship to motion bolt surface damage with no pressure of can holding out against when to motion bolt turning is provided for above-mentioned the deficiencies in the prior art.
For solving the problems of the technologies described above, the present invention is by the following technical solutions: comprise thimble body, described thimble body consists of cylinder and the round platform that is connected to cylinder end, described cylinder and round platform coaxially arrange and are integral type structure, the bottom surface diameter of described round platform is 115～118mm, the upper bottom surface diameter of described round platform is 30～35mm, and described round platform cone angle is 59～61 °.
The removable circular cone that is connected with also on the upper bottom surface of described round platform, this circular cone cone angle equates with round platform cone angle, the bottom surface of this circular cone and the upper bottom surface of round platform is close to and the bottom surface diameter of circular cone and the upper bottom surface equal diameters of round platform.
The invention has the beneficial effects as follows: the lathe thimble of motion bolt in diesel engine cylinder of using for factory ship of the present invention is by the design of ad hoc structure size, while can be used as motion bolt turning, hold out against parts, can make the cylindrical Vehicle Processing of motion bolt become pratical and feasible, and because this thimble holds out against in the endoporus of motion bolt, to the surface of motion bolt without crushing.
Further, the removable circular cone that is connected with also on the upper bottom surface of described round platform, this circular cone cone angle equates with round platform cone angle, the bottom surface diameter of this circular cone and the upper bottom surface equal diameters of round platform, like this by installing after above-mentioned circular cone at the upper bottom surface of round platform, just can other less workpiece of Vehicle Processing internal diameter, expanded the scope of application.
Accompanying drawing explanation
Fig. 1 is that the present invention uses the side-looking structural representation of the lathe thimble of motion bolt in diesel engine cylinder for factory ship.
Fig. 2 is that the present invention uses the decomposition texture schematic diagram of the lathe thimble of motion bolt in diesel engine cylinder for factory ship.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
Because lathe is prior art, therefore do not show in the accompanying drawings.
As shown in drawings, the lathe thimble of using motion bolt in diesel engine cylinder for factory ship of the present invention, comprises thimble body 1, and described thimble body 1 consists of cylinder 1.1 and the round platform 1.2 that is connected to cylinder 1.1 ends.Described cylinder 1.1 and round platform 1.2 coaxially arrange, and the bottom surface diameter d 1 of described round platform 1.2 is 115～118mm.The upper bottom surface diameter d 2 of described round platform 1.2 is 30～35mm.Described round platform cone angle a1 is 59～61 °.In the present embodiment, described round platform bottom surface diameter is 115mm, and the upper bottom surface diameter of described round platform is 30mm, and described round platform cone angle is 60 °.Wherein round platform cone angle refers to the maximum angle between two buses of round platform in Fig. 1.
Lathe thimble of the present invention adopts the structural design of above-mentioned specific dimensions, is through testing and final definite technical scheme many times, is not the structure that the simple size amplification of existing lathe thimble is obtained.This specific dimensional structure can firmly hold out against the pipe fitting that the such diameter of motion bolt is large, length is long on the one hand, and in holding out against process because this specific dimensional structure is enough large, top power is strong, in turning process, motion bolt integral body can not rock, be offset, effective guarantee the Vehicle Processing of motion bolt, ensured Vehicle Processing precision.In addition, the lathe thimble of this specific dimensions structure can meet the processing of the motion bolt of different-diameter size, has versatility.The relatively existing lathe thimble of lathe thimble of next this specific dimensions, size is much bigger, and economize material, material-saving is also the problem that is starved of consideration, and the position that holds out against of lathe thimble of the present invention is designed to frustum cone structure, circular cone project organization relatively of the prior art, can reach the object of good province material, material-saving.Finally the lathe top needle construction of this specific dimensions structure is very succinct, by parts, is formed, and without assembling, directly clamping can use, have save time, labour-saving advantage, be convenient to the Vehicle Processing of motion bolt.
As improvement project of the present invention, the removable circular cone 2 that is connected with also on the upper bottom surface of described round platform 1.2, this circular cone 2 is realized removable connection by the screwed hole 1.21 that is inlaid in the bolt 2.1 of bottom surface and match with bolt 2.1 screw threads and be located at round platform 1.2 upper bottom surfaces.This circular cone cone angle a2 equates with round platform cone angle a1, and the upper bottom surface of the bottom surface of this circular cone 2 and round platform 1.2 is close to and the bottom surface diameter of circular cone 2 and the upper bottom surface equal diameters of round platform 1.2.Setting up of circular cone, adds that circular cone is removable being connected on round platform like this, and in the time need to processing other pipe fittings of little internal diameter, this lathe thimble can also be used in the same old way like this, has increased the scope of application of lathe thimble, has more versatility.
