Abstract
The utility model provides a take mounting hole structure in exhaust hole, include: the valve bridge is connected with the valve bridge through a guide rod, one end of the guide rod is connected with the valve bridge in a sliding mode, the other end of the guide rod is fixedly connected with the cylinder cover, and an exhaust hole is formed in one side of the cylinder cover; the mounting hole structure with the exhaust hole provided by the utility model is additionally provided with the exhaust hole, so that most of air in the mounting hole can be smoothly exhausted, and high-pressure air which obstructs the mounting is prevented from being formed; due to the existence of the exhaust hole, the guide rod does not need to be changed, and the strength and the installation precision of the guide rod are favorably ensured.
Description
Technical Field
The utility model belongs to the technical field of the cylinder cap cooling, concretely relates to take mounting hole structure in exhaust hole.
Background
At present, more and more valve bridge guide mechanisms are applied to engines. The valve bridge guide rod is used as an important component part in a guide mechanism and is increasingly applied. The valve bridge guide rod is generally of a cylindrical structure and is fixed on a cylinder cover datum plane. The valve bridge is guided in a certain fixed direction by the cylindrical surface contact. The installation tolerances of the valve bridge guide lever itself have a great influence on the guiding function. If the verticality deviation between the valve bridge guide rod and the guide reference surface is overlarge, the original guide function is lost, and the abnormal abrasion of the valve bridge is caused. When the valve bridge guide rod is installed on the blind hole, air in the installation hole cannot be removed, high-pressure compressed air is formed often, and the valve bridge guide rod is prevented from being pressed in. The valve bridge guide rod is pressed in batch by a machine. When the pressure of the internal compressed air is too high, the valve bridge guide rod is not pressed in place, and the top of the valve bridge guide rod can collide with the valve bridge. In addition, the verticality of the valve bridge guide rod can be influenced, and the deviation of the guide direction is caused.
The Chinese patent application with the publication number of CN108868938A discloses a valve bridge with increased guide fit length, wherein the valve bridge comprises a valve bridge guide rod and a valve bridge body, the valve bridge body is provided with a valve bridge guide hole, and the valve bridge guide hole is used for installing the valve bridge guide rod. The valve bridge is provided with the valve bridge inner reaming hole at the bottom of the valve bridge guide hole, so that the guide matching length is increased, the space is fully utilized, the oil storage space is increased, and lubrication is facilitated.
It can be seen that the valve bridge guide rod in the prior art mainly focuses on designing the inner reaming hole of the valve bridge at the bottom of the valve bridge guide hole to increase the guide matching length, and the excessive pressure of the internal compressed air can cause the deviation of the guide direction when the guide rod is installed.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a take mounting hole structure in exhaust hole aims at solving among the prior art the too big problem that can cause the direction of direction to take place the deviation of inside compressed air's pressure when the installation guide bar.
For realizing above-mentioned technical purpose, reach above-mentioned technological effect, the utility model discloses a following technical scheme realizes:
the utility model provides a take mounting hole structure in exhaust hole, include: the valve bridge is connected with the valve bridge in a sliding mode, the other end of the guide rod is fixedly connected with the cylinder cover, and an exhaust hole is formed in one side of the cylinder cover.
Preferably, one end of the guide rod, which is connected with the cylinder head in a sliding manner, is further provided with a guide surface, and the guide surface is of a conical structure.
Preferably, the guide rod is connected with the cylinder cover in an interference fit mode.
The utility model has the advantages that:
1. the utility model provides a take mounting hole structure of exhaust hole has increased the exhaust hole for most air in the mounting hole can be discharged smoothly, prevents to form the highly-compressed air who hinders the installation.
2. The utility model provides a take mounting hole structure of exhaust hole because the existence in exhaust hole, just need not do the change to the guide bar again, is favorable to guaranteeing the intensity and the installation accuracy of guide bar.

Fig. 1 is a schematic overall structure diagram of a mounting hole structure with an exhaust hole according to the present invention;
fig. 2 is a cross-sectional view of the mounting hole structure with the exhaust hole of the present invention.
In the figure, 100 denotes a cylinder head, 101 denotes a valve bridge, 102 denotes a guide rod, 103 denotes an exhaust hole, and 104 denotes a guide surface.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly apparent, the present invention is further described in detail by the following embodiments with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
The utility model provides a take mounting hole structure in exhaust hole, as shown in figure 1, figure 2, include:
a guide rod 102 and a cylinder cover 100, wherein one end of the guide rod 102 is connected with a valve bridge 101 in a sliding manner, the other end of the guide rod 102 is fixedly connected with the cylinder cover 100, and one side of the cylinder cover 100 is also provided with an exhaust hole 103 (shown in fig. 2); because the cylinder cover 100 is internally provided with structures such as an air passage, a water passage and the like, the mounting hole of the guide rod 102 is generally designed to be a blind hole, when the guide rod 102 is pressed and installed, air between the guide rod 102 and the mounting hole on the cylinder cover 100 can be discharged along the exhaust hole 103, compressed air cannot be generated, the guide rod 102 can be smoothly pressed and installed in place, and the pressing and installing precision is ensured.
In one embodiment, the end of the guide rod 102 slidably coupled to the cylinder head 100 is further provided with a guide surface 104, and the guide surface 104 has a tapered configuration.
In some embodiments, the guide rod 102 is attached to the cylinder head 100 by an interference fit.
Reference in the specification to "some embodiments," "one embodiment," or "an embodiment," etc., means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, the appearances of the phrases "in some embodiments," "in one embodiment," or "in an embodiment," or the like, in various places throughout this specification are not necessarily referring to the same embodiment.
