Abstract
The utility model discloses a connection plate of an engine oil injection pump, which is a flange-shaped structure. A mounting hole for installing the oil injection pump is arranged in the middle of the connection plate, one end of the connection plate connected with a cover plate of an engine gear chamber is a sealing surface which is provided with an annular mounting groove. The mounting groove is coaxially arranged at the periphery of the mounting hole, and the connection plate is further provided with a coaxiality positioning device. A sealing groove for installing a sealing ring is arranged on the sealing surface of the connection plate of the oil injection pump, and the positioning device is arranged on the connection plate of the oil injection pump, thereby being good in sealing effect and convenient to assemble, disassemble, install and position, and guaranteeing coaxiality of parts.
Description
Technical field
The utility model relates to the engine mechanical technical field, relates to a kind of injection pump of engine land in particular.
Background technique
At present, the installation of domestic injection pump of engine is connected with the gear chamber cover plate by the Injection Pump land, and the Injection Pump land is when being connected with the gear chamber cover plate, need pad to prevent leakage of oil, but pad order easy deformation of a specified duration, and then cause occurring the oil impregnate phenomenon, and when changing pad, because of pad is out of shape, also can cause the sealing surface out-of-flatness, cause the sealability between Injection Pump land and the gear chamber cover plate to descend.
The model utility content
The purpose of this utility model is to provide a kind of injection pump of engine land, sealing surface at the Injection Pump land is provided with the seal groove that seal ring can be installed, also on the Injection Pump land, be provided with positioning device, therefore not only good sealing effect, easy accessibility, and installing and locating is convenient, has guaranteed the coaxality of part.
The utility model is to adopt following technological scheme to realize above-mentioned purpose: a kind of injection pump of engine land, it is a flange-like structure, this land middle part is provided with the mounting hole that is used to install Injection Pump, the end that this land is connected with the engine gear room cover plate is a sealing surface, on the sealing face, be provided with the mounting groove of an annular, it is peripheral and coaxial with this mounting hole that this mounting groove is located at mounting hole, also is provided with a proper alignment positioning apparatus on this land.
As further specifying of such scheme:
Preferably, described coaxial positioning apparatus is a positioning spigot, and this positioning spigot is the counterbore shape structure that is located at the mounting hole outer rim.
Preferably, the cross section of described mounting groove is rectangle or arc.
Preferably, described sealing surface is provided with plural screw, and this screw is evenly distributed between mounting groove and the mounting hole.
The beneficial effect that the utility model adopts above technological scheme to reach is:
1. the utility model is provided with the mounting groove of an annular on the sealing surface of land, be used for installing the O RunddichtringO,, make it can bring into play good seal action by the compressibility of O RunddichtringO, can not have influence on the flatness of sealing surface again, and dismounting is easy to maintenance.
2. the utility model also is provided with a positioning spigot in the mounting hole outer rim and replaces locating stud of the prior art, can not only guarantee to install the coaxality of each part of back, and has simplified the structure of land.

Embodiment
For further setting forth 26S Proteasome Structure and Function of the present utility model, below in conjunction with accompanying drawing and preferred embodiment the utility model is elaborated, but be to be understood that protection domain of the present utility model is not subjected to the restriction of embodiment.
As Fig. 1, shown in Fig. 2 and Fig. 4, the utility model is a kind of injection pump of engine land, this land is a flange-like structure, be provided with the mounting hole 1 that is used to install Injection Pump at the land middle part, the end that this land is connected with the engine gear room cover plate is a sealing surface 2, on sealing face 2, be provided with the mounting groove 3 of an annular, it is peripheral and coaxial with this mounting hole 1 that this mounting groove 3 is located at mounting hole 1, between mounting groove 3 and mounting hole 1, be evenly distributed with four screws 5, also be provided with the positioning spigot 4 of a counterbore shape in mounting hole 1 outer rim, be used for to the Injection Pump location with the coaxality after guaranteeing to install.
Fig. 3 is sectional view B-B of the present utility model, and as shown in FIG., this mounting hole 1 is a second order hole, so that adaptive with Injection Pump; The cross section of this mounting groove 3 is rectangular, and behind the installation O RunddichtringO, the utility model is spirally connected by screw 5 and engine gear room cover plate by screw, and the gear chamber cover plate presses the O RunddichtringO to guarantee excellent sealing performance.
Only one of the utility model preferred embodiment shown in the utility model the foregoing description and the accompanying drawing; can not limit to the utility model with this; under the condition that does not break away from the utility model marrow, any change that those skilled in the art did all belongs to protection domain of the present utility model.
