Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in detail.
Provide a kind of engine corner marking instrument mounting structure according to an aspect of the present utility model, as shown in Figure 1 and Figure 2, this engine corner marking instrument mounting structure comprises:
For with bolted first flange 1 of engine damper pulley and the second flange 2 for being connected with the first flange 1, wherein,
As shown in Figure 3, Figure 4, the first flange 1 is provided with the groove 101 for coordinating with engine damper pulley spacer for bolt; The first mounting hole 102 for coordinating with the bolt head of engine damper pulley bolt is provided with bottom groove 101; Be distributed in outside the first mounting hole 102, for installing at least two the second mounting holes 103 of the second flange 2;
As shown in Figure 5, the second flange 2 one end face is provided with at least two counterbores 201 for being connected with the second mounting hole 103; Other end is provided with at least two waist holes 202 for installing engine corner marking instrument.
In the utility model embodiment, first flange 1 is connected with engine damper pulley bolt, the counterbore 201 of second flange 2 one end is connected with the second mounting hole 103 of the first flange 1, the other end is connected with engine corner marking instrument, and then the installation achieved engine corner marking instrument, in installation process, without the need to dismantling engine damper pulley bolt, and the original design point of engine can not be changed, easier for installation.And the shape of the first mounting hole 102 xsect is regular hexagon, just can match with the bolt head of engine damper pulley bolt, it is appreciated of course that, in the utility model embodiment, specifically do not limit the shape of the first mounting hole 102 xsect, its shape can make corresponding adjustment according to the shape of the bolt head of damper pulley bolt.In addition, it will also be appreciated that, in the utility model embodiment, first mounting hole 102 and the second mounting hole 103 both can be and be uniformly distributed, also can be non-uniform Distribution, corresponding adjustment can be carried out to the first mounting hole 102 to the distribution situation of the second mounting hole 103 according to the installation situation of reality, its distribution situation is not specifically limited.
Particularly, in the utility model embodiment, when carrying out frock, first the first flange 1 is fixed on damper pulley bolt, when being fixed, regular hexagon first mounting hole 102 mainly through the first flange 1 is fixed with the outer-hexagonal face of damper pulley bolt.Wherein, first flange 1 can be mounting flange or counter flange, when the first flange 1 is mounting flange, then the first flange 1 is coordinated by the mode of transition fit with engine damper pulley bolt, because engine only has axial rotation herein in theory, only there is radial force and there is not axial force, in real engine running, although may the problems such as vibration be there is, but by the transition fit between the first flange 1 and engine damper pulley bolt is optimized, still good fixation can be played, and reliable.When the first flange 1 is counter flange, then the first flange 1 is coordinated by the mode of clearance fit with engine damper pulley bolt, still can play good fixation.
Further, because the first flange 1 the second mounting hole 103, second flange 2 be provided with for being connected with the second flange 2 is provided with the counterbore 201 for being connected with the first flange 1, therefore, the first flange 1 can be fixedly connected with the second flange 2 by bolt.Wherein, when connecting, first to use the right alignment of miking second flange 2, its right alignment being controlled, in the scope needed for the work of engine corner marking instrument, then progressively tightening set bolt.And engine corner marking instrument is connected with the waist hole 202 on the second flange 2, therefore, when the waist hole 202 of adjustment second flange 2, can realize adjusting the right alignment of engine corner marking instrument simultaneously.It is appreciated of course that, in the utility model embodiment, the quantity in waist hole 202, size and distribution are not specifically limited.
Further, in the utility model embodiment, also using the surface of contact of damper pulley spacer for bolt, the first flange 1, second flange 2 as locating surface, ensure that the verticality of the second flange 2 and engine crankshaft, and engine corner marking instrument is installed on the second flange 2 by the waist hole 202 on the second flange 2, again by the matching design of the second flange 2, finally achieve engine corner marking instrument consistent with the second flange 2 right alignment and verticality.Therefore, this engine corner marking instrument mounting structure and engine corner marking instrument can couple together under the condition not changing engine complete machine situation, can also reach higher test accuracy simultaneously.
Above-described is preferred implementation of the present utility model; should be understood that the ordinary person for the art; can also make some improvements and modifications not departing under principle prerequisite described in the utility model, these improvements and modifications are also in protection domain of the present utility model.
