Description
Technical Field
The utility model relates to a positioner of diesel engine spare part, especially a positioner of dismouting diesel engine main shaft tile hour belong to diesel engine auxiliary fixtures technical field.
Background
In long-term maintenance use or fault repair of a marine diesel engine, parts are frequently required to be disassembled and inspected, particularly when a main shaft bush is disassembled and assembled, due to the fact that the space in a cabin is narrow, the environment is severe, and the construction difficulty is high, the main shaft bush on the main shaft bush is disassembled, assembled or replaced with certain difficulty under the condition that a crankshaft is kept in a rack, and when the main shaft bush enters and exits along a curved surface of the crankshaft in operation, the main shaft bush is extremely easy to damage due to lack of limitation and guidance, the main shaft bush is difficult to be installed in place, so that the working efficiency is low, installation accuracy and lubrication of follow-up main shaft bushes are seriously influenced, and the service life of the main shaft bush is shortened.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a simple structure, with low costs, convenient operation's diesel engine main shaft tile adjustment positioner.
The utility model discloses a following technical scheme realizes:
a diesel engine main shaft bush adjusting and positioning device comprises a positioning plate, a positioning pin and a plurality of magnetic blocks, wherein the positioning pin and the plurality of magnetic blocks are respectively positioned on two sides of the thickness of the positioning plate; the locating pin is fixed on locating plate one end downside, the several magnetism piece is fixed respectively on the downside on the locating plate other end, and locating plate other end terminal surface is equipped with the draw-in groove.
The object of the invention is also achieved by the following technical measures.
In the diesel engine main bearing shell adjusting and positioning device, the shape of the clamping groove is matched with the shape of one side of the diesel engine main bearing shell.
In the adjusting and positioning device for the main bearing shell of the diesel engine, the positioning plate is of a reverse L-shaped structure.
In the adjusting and positioning device for the main bearing bush of the diesel engine, the positioning pin and the magnetic block are adhered to the positioning plate through glue.
The utility model discloses simple structure is compact, and is with low costs, convenient operation, safe and reliable. In the process of maintaining and using the diesel engine, on the basis that the crankshaft keeps in situ, the spindle bush can be accurately positioned and guided through the clamping groove on the end face of the positioning plate, unnecessary damage to the spindle bush in the process of dismounting and mounting can be effectively avoided, smooth dismounting and mounting of the spindle bush are guaranteed, meanwhile, the spindle bush can be quickly and accurately mounted in place, the dismounting and mounting efficiency of the spindle bush is greatly improved, the mounting precision of subsequent spindle bushes is improved, and the service life of the spindle bush is prolonged.
The advantages and features of the invention will be illustrated and explained by the following non-restrictive description of preferred embodiments, which are given by way of example only with reference to the accompanying drawings.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a left side view of fig. 1.
Detailed Description
The present invention will be further explained with reference to the drawings and examples.
As shown in fig. 1 and fig. 2, the utility model discloses a locating plate 1, locating pin 2 and two magnetic block 3 are located the thickness both sides of locating plate 1 respectively, and locating plate 1 is anti-L shape structure. The positioning pin 2 is firmly adhered to the lower side of the left end of the positioning plate 1 through high-strength glue, the two magnetic blocks 3 are respectively adhered to the upper side and the lower side of the right end of the positioning plate 1 through the high-strength glue, a clamping groove 11 is formed in the end face of the right end of the positioning plate 1, and the shape of the clamping groove 11 is matched with that of one side of the main bearing bush 4 of the diesel engine.
When dismouting diesel engine main shaft tile 4, will the utility model discloses a locating pin 2 taps in the locating hole in the diesel engine frame, then adjusts locating plate 1's position, and accurate positioning in the draw-in groove 11 of 1 right-hand member of locating plate is gone into respectively to the upper and lower end that makes diesel engine main shaft tile 4 ensures simultaneously that main shaft tile 4 can free rotation in draw-in groove 11, closely adsorbs locating plate 1 in the diesel engine frame through magnetic block 3 at last. The crankshaft is coiled, and under the guiding action of the clamping groove 11, the main shaft bush 4 can smoothly enter and exit the curved surface of the crankshaft along the clamping groove 11, so that the disassembly and the assembly of the main shaft bush 4 are completed.
In addition to the above embodiments, the present invention can also have other embodiments, and all technical solutions formed by equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
