Description

Technical Field

[0001] The utility model belongs to the technical field of the machining of medium-speed marine diesel engines, and particularly relates to a machining tooling for a medium-speed marine diesel engine body. Background Art

[0002] A medium-speed marine diesel engine is a type of diesel engine, which is installed on a ship's hull as a power component of the hull. The body of a medium-speed marine diesel engine is slightly larger in size, with a complex overall structure and a relatively large weight. Therefore, during the production and machining process of the diesel engine, such as during the machining process of the diesel engine body, it is necessary to position the heavy and large-sized body through a tooling.

[0003] The body in the locked state after positioning can be machined in a relatively safe and stable state. Specifically, during the machining process, the prior art uses mechanisms such as pressing plates to lock and press the heavy and large-sized body, and keeps it in a positioned state after locking and pressing.

[0004] Specifically, a hoisting device hoists the heavy body to a tooling table, and uses the pressing plates on the tooling table to press on the body. However, since the position where the pressing plate presses on the body is often fixed, and when it is transferred from below the hoisting to the tooling table, it is very easy for the material pressing position of the pressing plate not to correspond to the position where the pressing plate is located. At this time, it is necessary to hoist the heavy diesel engine body again, correct the position and then lower it.

[0005] However, in the actual working process, it is necessary to correct the position of the diesel engine body multiple times to ensure that the material pressing positions of all the pressing plates correspond to the positions where the pressing edges are located on the tooling. This makes the feeding and pressing processes relatively cumbersome and difficult.

[0006] Meanwhile, during the machining process, once some of the pressing plates are not fully locked, under the impact force of the machining equipment, the balance of the diesel engine body is very easy to be lost, and then it tilts and moves. The tilting and moving not only easily lead to serious potential safety hazards, but also easily cause damage to the diesel engine body. Content of the Utility Model

[0007] Based on the above background, the purpose of the utility model is to provide a machining tooling for a medium-speed marine diesel engine body.

[0008] To achieve the above purpose, the utility model adopts the following technical solutions:

[0009] A machining tooling for a medium-speed marine diesel engine body includes a feeding tooling for the diesel engine body;

[0010] The feeding tooling for the diesel engine body includes a first limiting ring seat and a second limiting ring seat which are symmetrically arranged up and down, and a plurality of locking and pressing mechanisms are arranged to roll between the first limiting ring seat and the second limiting ring seat;

[0016] Preferably, the base assembly further comprises rollers fixedly mounted at the top and bottom of the base respectively, and the rollers respectively support and roll between the first limiting ring seat and the second limiting ring seat.

[0017] Preferably, annular guide grooves for limiting the roller are respectively provided on the side walls of the first limiting ring seat and the second limiting ring seat that face each other.

[0018] Preferably, a convex sliding seat is fixedly connected to the inner end of the sliding screw, a convex sliding groove slidably connected to the convex sliding seat is provided on the adjusting column, and the convex sliding seat is limitedly slidable in the convex sliding groove.

[0019] Preferably, a plurality of material carrier mechanisms are fixedly connected to the inner side wall of the second limiting ring seat;

[0020] The material carrier mechanism comprises an L-shaped carrier welded on the second limiting ring seat, and a horizontally arranged carrier seat is welded on the top of the L-shaped carrier;

[0021] The carrier is slidably assembled with a resisting convex plate component.

[0022] Preferably, the abutment convex plate assembly comprises an abutment plate slidably connected to the outer side of the carrier, and the inner side wall of the abutment plate is integrally formed with a protruding abutment convexity;

[0023] A sliding opening is provided on the outer side of the carrier, a sliding opening screw is fixedly connected in the sliding opening, the lower end of the resistance plate is slidably connected to the sliding opening screw, and an inner push nut for pushing the resistance plate to move is threadedly connected on the sliding opening screw.

[0024] Preferably, the machining tooling for the marine medium-speed diesel engine body further includes an anti-creeper ring mechanism hinged between the upper ends of a pair of adjusting columns.

[0025] Preferably, the anti-creeper ring mechanism includes an anti-creeper ring, and a pair of ear plates are respectively welded on both sides of the anti-creeper ring. One ear plate is hinged to the upper end of one adjusting column through a fixed pin shaft;

[0027] The utility model has the following beneficial effects:

After the anti-creeper ring is flipped open during the loading process, after the pressure plate is locked, the anti-creeper ring is flipped to the other side and the insertion pin shaft between the other ear plate and the other adjusting column is fixedly pinned. That is, after the insertion pin shaft is aligned with the through holes on the ear plate and the adjusting column, it is fixedly pinned. During the working process, once the diesel engine body loses the locking pressure and creeps, when it touches the anti-creeper ring, it is blocked by the anti-creeper ring to avoid further disengaging from the tooling and causing a safety accident.

[0042] Embodiment 1

[0043] As Figure 1-5As shown in the figure, a processing tooling for a marine medium-speed diesel engine body includes a loading tooling for the diesel engine body; the loading tooling for the diesel engine body includes a first limiting ring seat 1 and a second limiting ring seat 2 which are symmetrically arranged up and down. At the same time, a number of loading frame mechanisms are fixedly connected to the inner side wall of the second limiting ring seat; the loading frame mechanism includes an L-shaped carrier 4 welded to the second limiting ring seat, and a horizontally arranged carrier seat 41 is welded to the top of the L-shaped carrier 4; a contact convex plate assembly is slidably assembled on the carrier seat 41.

[0044] Specifically, the contact convex plate assembly includes a contact plate 42 slidably connected to the outer side of the carrier seat 41, and a protruding contact protrusion is integrally formed on the inner side wall of the contact plate 42; a sliding opening is formed on the outer side of the carrier seat 41, a sliding opening screw 43 is fixedly connected in the sliding opening, the lower end of the contact plate 42 is slidably connected to the sliding opening screw 43, and an inner push nut 431 for pushing the contact plate 42 to move inward is threadedly connected to the sliding opening screw 43.

[0045] During the working process, a crane is used to hoist the heavy diesel engine body into the center position of the concentric and same-sized first limiting ring seat 1 and second limiting ring seat 2. Under the limitation of the first limiting ring seat 1 and the second limiting ring seat 2, during processing, once the diesel engine body loses balance and breaks away from the first limiting ring seat 1 and the second limiting ring seat 2, a safety accident may occur. That is, the first limiting ring seat 1 and the second limiting ring seat 2 form a limiting structure to prevent the diesel engine body from moving outward once a processing failure occurs.

[0046] The loaded body is supported on the carrier seat 41, and the inner push nut 431 is screwed inward until the contact plate 42 - contact protrusion structure is in contact with and locked to the lower end of the side wall of the diesel engine body.

[0047] Embodiment 2

[0048] As Figure 1-5 shown, on the basis of the structure of Embodiment 1 in this embodiment, a number of locking and pressing mechanisms are arranged to roll between the first limiting ring seat 1 and the second limiting ring seat 2. By arranging the locking and pressing mechanisms to roll, on the one hand, the top of the diesel engine is locked, and on the other hand, the position of the locking and pressing mechanism can be conveniently adjusted to facilitate the locking and pressing mechanism to correctly lock to the correct position. The traditional method of correcting the diesel engine body is not only cumbersome but also difficult to operate.

[0049] Specifically, the locking and pressing mechanism includes a base assembly that rolls between the limiting ring seats. Specifically, the base assembly includes a base 35, and the bottoms of the following sliding screws 34 and adjusting columns 31 are respectively fixedly connected to the inner and outer positions of the top of the base 35.

[0050] Meanwhile, the base assembly further includes rollers 36 fixedly installed at the top and bottom positions of the base 35 respectively (specifically, the rollers 36 include a turbine and a roller body rotatably connected to a wheel frame), and the rollers 36 are respectively supported and roll between the first limit ring seat 1 and the second limit ring seat 2. To prevent the rollers 36 from derailing, annular guide grooves for limiting the rollers 36 are respectively provided on the mutually facing side walls of the first limit ring seat 1 and the second limit ring seat 2. The rollers 36 are limited to roll between the annular guide grooves.

[0051] Meanwhile, the first limit ring seat 1 and the second limit ring seat 2 are fixedly connected by welding a number of columns that are more numerous than the rollers 36 between them.

[0052] An adjusting column 31 is fixedly connected to the outer side of the top of the base 35, and a downward sliding screw 34 is fixedly connected to the inner side of the top of the base 35 assembly. A pressing plate 33 is slidably connected to the downward sliding screw 34; a pressing nut for pressing the pressing plate 33 is threadedly connected to the downward sliding screw 34.

[0053] During the working process, after adjusting the position of the base 35 assembly in the above manner, the pressing plate 33 is slid downward and pressed against the machine body. It remains firmly pressed under the positioning of the pressing nut.

[0054] To adjust the relative distance between the pressing plate 33 and the machine body, a long rectangular adjustment opening 331 is provided on the pressing plate 33, and the downward sliding screw 34 can slide vertically and horizontally in the long rectangular adjustment opening 331.

[0055] Meanwhile, to maintain the balance of the adjusting pressing plate 33, a supporting cushion block 32 that supports the inner side of the pressing plate 33 is slidably assembled and connected to the adjusting column 31. The outer end of the adjusting pressing plate 33 is supported on the supporting cushion block 32.

[0056] Similarly, the supporting cushion block 32 needs to be adjusted synchronously with the height of the pressing plate 33.

[0057] Specifically, a sliding screw 321 is slidably connected to the supporting cushion block 32, the sliding screw 321 is slidably connected to the adjusting column 31, and a locking nut for locking and pressing the supporting cushion block 32 is threadedly connected to the sliding screw 321.

[0058] Specifically, the inner end of the sliding screw is fixedly connected with a convex sliding seat, and a convex sliding groove A for slidably connecting the convex sliding seat is provided on the adjusting column 31, and the convex sliding seat is limited to slide in the convex sliding groove A.

[0059] After sliding and adjusting the supporting pad 32, turn the locking nut inward until it presses against the supporting pad 32, and the supporting pad 32 presses against the adjusting column 31 to maintain positioning. Since the supporting pad 32 only serves to keep the pressure plate 33 balanced, and the pressure of the pressure plate 33 is mainly exerted on the locking body.

[0060] Embodiment 3

[0061] As Figure 1-5 shown, on the basis of the structure of Embodiment 2, the marine medium-speed diesel engine body processing tooling further includes an anti-creeper ring mechanism hinged between the upper ends of a pair of adjusting columns 31. The anti-creeper ring mechanism has the same principle as the anti-creeper of the above-mentioned first limit ring seat 1 and the second limit ring seat 2, aiming to prevent the body from creeping upward once the locking pressure of the pressure plate 33 is unstable.

[0062] Specifically, the anti-creeper ring mechanism includes an anti-creeper ring 5, and a pair of ear plates 51 are respectively welded on both sides of the anti-creeper ring 5, and one side ear plate 51 is hinged to the upper end of one side adjusting column 31 through a fixed pin shaft. Specifically, the adjusting columns 31 are arranged in a circular array, and the anti-creeper ring 5 is hinged to two adjusting columns 31 arranged at an interval of 180 degrees.

[0063] After the anti-creeper ring 5 is turned over and opened during the feeding process, after the pressure plate 33 is locked, turn the anti-creeper ring 5 until the insertion pin shaft 52 between the other side ear plate 51 and the other side adjusting column 31 is fixed. That is, align the insertion pin shaft 52 with the through holes on the ear plate 51 and the adjusting column 31 and then fix it. It is realized that once the diesel engine body loses the locking pressure during the working process, during the creeping process, when it touches the anti-creeper ring 5, it is prevented from further detaching from the tooling under the blocking of the anti-creeper ring 5, thus causing a safety accident.

[0064] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the essence of the present invention should also belong to the protection scope of the present invention.
