Description
Technical Field
The utility model relates to an equipment correction field specifically relates to a plug bush correcting device in marine diesel cylinder cap.
Background
In the assembly of the cylinder cover part of the marine diesel engine, the content of the plug bush assembled in a fuel injector hole is provided, and the assembly drawing of the cylinder cover part requires that a radial hole of the plug bush and a high-pressure fuel pipe hole of a cylinder cover body need to be aligned. The phenomenon that the radial hole of the plug bush is not aligned with the high-pressure oil pipe hole of the cylinder cover occurs in actual production, and sometimes occurs. The plug bush is arranged in a cylinder cover fuel injector hole in an interference fit mode, so that the radial direction of the plug bush with an incorrect assembly position is inconvenient to correct, and only the assembled plug bush can be disassembled in actual production, and a new plug bush is drawn to be reassembled.
The plug bush is arranged in the cylinder cover fuel injector hole in an interference mode, and the interference position is located at the lower end of the plug bush. The stress point of the plug bush correcting device is positioned on the upper part of the plug bush, and the stress transmission route is long and the stress point is not good. This plug correction device risks two points: when the interference part of the plug bush assembly is stressed greatly, the device is not easy to correct; the plug bush belongs to a thin-wall part, and the radial hole is easy to deform under stress.

It is an object of the present invention to solve at least the above problems and to provide at least the advantages which will be described later.
The utility model also has the purpose of simple and reliable positioning, convenient use and accurate correction and force application.
In order to realize according to the utility model discloses these objects and other advantages, provide a plug bush correcting device in marine diesel cylinder cap, include: the force applying device comprises a force applying element, a transmission element connected with the force applying element, a positioning element arranged on the transmission element and a power input element arranged on the transmission element.
Preferably, the force application element is an eccentric wheel capable of radially pushing the positioning element to rotate.
Preferably, the transmission element is a connecting rod for transmitting torque values to the eccentric.
Preferably, the positioning element is a plug bush which is inserted into a high-pressure oil pipe of the cylinder cover and plays a role in axial positioning.
Preferably, the power input unit is a handle embedded in the transmission element to facilitate power input.
Preferably, a nut for fixing the force application element is further included for fixing the eccentric.
Preferably, the plug bush correcting device takes a step structure of the orifice of the high-pressure oil pipe hole as a positioning hole, and the plug bush is prevented from being increased due to scratching of the high-pressure oil pipe hole.
The utility model has the advantages that:
(1) the plug bush correcting device is small in size, simple in structure and convenient to manufacture, and can correct the radial position of the plug bush of the machine type. The device has reference significance for correcting the positions of parts with similar structures, and can be popularized and applied.
Popularization and application: when the diameter and the depth of the high-pressure oil pipe hole are changed, the outer diameter and the length of the plug bush are changed in time; when the radial hole of the plug bush changes, the diameter size of the eccentric wheel is changed in time.
(2) The positioning is simple and reliable, the use is convenient, and the correction and force application are accurate.
Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention.

Detailed Description
The present invention is further described in detail below with reference to the drawings so that those skilled in the art can implement the invention with reference to the description.
It will be understood that terms such as "having," "including," and "comprising," as used herein, do not preclude the presence or addition of one or more other elements or groups thereof.
In one embodiment, as shown in fig. 1 and 2, the utility model provides a plug bush correcting device in marine diesel engine cylinder cap, include: the force applying device comprises a force applying element, a transmission element connected with the force applying element, a positioning element arranged on the transmission element and a power input element arranged on the transmission element.
The force application element is an eccentric wheel 1 and can radially push the positioning element to rotate.
The transmission element is a connecting rod 2 used for transmitting a torque value eccentric wheel 1.
The positioning element is an insert sleeve 3 and is inserted into a high-pressure oil pipe hole 6 of the cylinder cover, and the insert sleeve 3 plays a role in axial positioning.
The power input unit is a handle 4, and the handle 4 is embedded in the transmission element, so that power input is facilitated.
A nut 5 for fixing the force application element is also included for fixing the eccentric 1.
The plug bush 3 correcting device takes the step structure of the orifice of the high-pressure oil pipe hole 6 as a positioning hole, and the plug bush 3 is prevented from being increased due to the scratch of the high-pressure oil pipe hole 6.
The design principle is as follows: the high-pressure oil pipe hole 6 can be used as a positioning hole, the inserting sleeve 3 is added for preventing the high-pressure oil pipe hole 6 from being scratched, the eccentric wheel 1 is designed for correcting the inserting sleeve 3 by utilizing the principle of camshaft radius change, and the connecting rod 2 rotates to apply force to the radial hole of the inserting sleeve 3.
