[0016] The utility model motorcycle engine suspension support mounting hole gauge will be further described below in connection with the drawings and specific embodiment. SPECIFIC EMBODIMENT

[0017] Referring to the drawings Figure 3 , 4This utility model relates to a motorcycle engine suspension bracket mounting hole inspection tool, comprising a base plate 1, a reference post, a measuring seat 5, and a measuring rod 6. The base plate is a rectangular plate. The reference post is fixed on the base plate and includes a single-step post 2, a double-step post 3, and a double-rod post 4. The single-step post is fixed to the bottom side of the base plate and is called the bottom reference post. Its step diameter and rod diameter are the same as the diameters of the bottom mounting post and mounting hole of the suspension bracket, respectively. There are two double-step posts, fixed on the left and right sides of the upper part of the base plate, respectively called the left reference post and the right reference post. Their large step diameter, small step diameter, and rod diameter are the same as the diameters of the left and right mounting posts, shock absorber holes, and mounting holes of the suspension bracket, respectively. The installation position of the reference post is based on the mounting holes of the qualified suspension bracket fitting onto the corresponding rods of the reference post. The height of the reference post is based on the condition that the surface of all mounting posts of the qualified suspension bracket is parallel to the surface of the base plate when the qualified suspension bracket is placed on the reference post. The double-rod post is located to the left of the left reference post and has two straight rods on the long strip step. The diameter of the straight rod matches the minor diameter of screw hole II; the position of the double rod column is such that after the qualified suspension bracket is placed on the reference column, the two straight rods on the double rod column are coaxial with the screw hole II of the qualified suspension bracket; the height of the double rod column is such that after the qualified suspension bracket is placed on the reference column, the bottom surface of the lug where the screw hole II is located contacts the surface of the long strip step of the double rod column; the measuring seat is a long rectangular shape, fixed on the outside of the left and right reference columns and in the same direction as the inclined support rod; the measuring seat is provided with two detection through holes, and the position and height of the detection through holes are such that after the qualified suspension bracket is placed on the reference column, the axis of the detection through holes is coaxial with the screw hole I of the qualified suspension bracket; the measuring rod is two long strip round rods, the diameter of the front section of which matches the minor diameter of screw hole I, and they are respectively inserted into the detection through holes; wherein, placing the qualified suspension bracket on the reference column means that each mounting hole of the qualified suspension bracket is respectively fitted onto the corresponding reference column, and the lower surface of each mounting column of the qualified suspension bracket contacts the upper surface of the step of the corresponding reference column. During the specific testing, each mounting hole of the suspension bracket to be tested is fitted onto the corresponding reference column. It is observed whether each mounting hole or damping hole of the suspension bracket to be tested can be smoothly fitted onto the round rod or small step of the corresponding reference column. Simultaneously, it is observed whether the lower surface of each mounting column of the suspension bracket to be tested is in contact with the upper surface of the step of the corresponding reference column. Then, it is observed whether screw hole II is fitted onto the two straight rods of the double-rod column, and whether the bottom surface of the lug containing screw hole II is in contact with the surface of the long strip step of the double-rod column. If so, the positional accuracy and perpendicularity of the mounting holes and damping holes of the suspension bracket to be tested, as well as screw hole II, are considered to meet the design requirements; otherwise, they are considered not to meet the design requirements. In fact, if the position or perpendicularity of any of the mounting holes, damping holes, or screw hole II of the suspension bracket to be tested does not meet the design requirements, the suspension bracket to be tested may not be able to be smoothly placed on the reference column.At this point, further observation is needed to determine which hole's position or perpendicularity is causing the suspension bracket to fail to be placed smoothly on the reference post, allowing for targeted adjustments or modifications. Additionally, push the two measuring rods on the measuring base forward and observe whether they smoothly enter screw hole I; if so, the positional accuracy and inclination of screw hole I are considered to meet design requirements; otherwise, they are considered not to meet design requirements. As can be seen from the above testing process, this utility model motorcycle engine suspension bracket mounting hole gauge has the characteristics of simple structure and convenient testing. It can intuitively test the positional accuracy, perpendicularity, or inclination of mounting holes, screw hole I, and screw hole II without the need for other measuring tools, thus improving testing efficiency and ensuring testing quality.

[0018] See appendix Figure 5 As a preferred technical solution, the motorcycle engine suspension bracket mounting hole inspection tool of this utility model also includes a mounting post thickness detection card. The mounting post thickness detection card is a rectangular thin plate with rectangular notches on two sides. One rectangular notch has a width equal to the minimum acceptable thickness of the mounting post, and the other rectangular notch has a width equal to the maximum acceptable thickness. During testing, the large and small rectangular notches of the mounting post thickness detection card are simply fitted onto the mounting post in the thickness direction. If the large rectangular notch can be fitted onto the mounting post, but the small rectangular notch cannot, then the thickness of the mounting post is considered to meet the design requirements; otherwise, it is considered not to meet the design requirements.

[0019] See appendix Figure 6 As one of the preferred technical solutions, the motorcycle engine suspension bracket mounting hole inspection tool of this utility model is further provided with a shock absorber hole depth detection component. The shock absorber hole depth detection component includes a detection post and a stop-go clip. The detection post is a stepped cylinder, the outer diameter of which matches the inner diameter of the qualified suspension bracket shock absorber hole, and its height is longer than the depth of the qualified suspension bracket shock absorber hole. The stop-go clip is a long, thin plate, with detection blades on both sides of the front section. The thickness of one blade edge is the maximum value of the difference between the height of the small step of the detection post and the depth of the qualified suspension bracket shock absorber hole, i.e., a thick blade; the thickness of the other blade edge is the minimum value of the difference between the height of the small step of the detection post and the depth of the qualified suspension bracket shock absorber hole, i.e., a thin blade. During testing, insert the small step of the testing column into the vibration damping hole, ensuring that the bottom surface of the small step of the testing column is in close contact with the bottom surface of the vibration damping hole; insert the thin and thick blades of the go-stop card between the bottom surface of the large step of the testing column and the upper surface of the vibration damping hole, respectively; if the thin blade of the go-stop card can be inserted but the thick blade cannot, the depth of the vibration damping hole is considered to meet the design requirements; otherwise, the depth of the vibration damping hole is considered to not meet the design requirements.

[0020] Obviously, the beneficial technical effects of this utility model of motorcycle engine suspension bracket mounting hole inspection tool are that it has a simple structure and is convenient for inspection, which not only improves inspection efficiency but also ensures inspection quality.
