[0024] Embodiment 1
[0025] As Figure 1-4As shown in the figure, the vehicle clearance measuring tool of this embodiment includes a base 100, a balance weight 101, a slider assembly 102, a turntable 103, a main scale 104, and a moving pointer 105. The base 100 includes a base plate and a column frame provided on the base plate. One side of the column frame is an open structure, and two guide rail grooves are vertically provided on the front side wall of the column frame. There are two balance weights 101, and the balance weights 101 are embedded in the base holes of the base plate through the protruding structures at the bottoms of the balance weights. The slider assembly 102 includes a slider body 1021. The rear side wall of the slider body 1021 is connected to the guide rail grooves through two pre-tightening members. By loosening the pre-tightening members, the slider assembly 102 can slide up and down along the guide rail grooves. The pre-tightening members are composed of welding bolts or studs 106 and nuts 107. The welding bolts or studs 106 are welded and fixed to the slider body 1021. Two compression springs 1022 and two limit balls are provided in the slider body 1021. The limit balls 1023 are connected to the front ends of the compression springs 1022, and the limit balls 1023 protrude from the holes on the front side wall of the slider body 1021. A rotating shaft 1024 is also provided on the front side wall of the slider body 1021. The rotating shaft 1024 is provided between the two limit balls 1023. The turntable 103 is rotatably connected to the rotating shaft 1024, and limit holes for cooperating with the limit balls 1023 are provided on the turntable 103. The main scale 104 includes a scale body and a fixed pointer. The fixed pointer is provided at the front end of the scale body. The moving pointer 105 is slidably provided on the scale body. The fixed pointer and the moving pointer are perpendicularly arranged with respect to the scale body. A turntable guide rail is provided on the front end face of the turntable 103. The scale body is inserted into the turntable guide rail and can slide along the turntable guide rail.
[0026] The measurement principle of the vehicle clearance measuring tool of this embodiment is as follows:
[0027] ① By vertically sliding the slider assembly 102 on the guide rail grooves of the base 100, the slider assembly 102 drives the turntable 103, the main scale 104, and the moving pointer 105 to adjust the height.
[0028] ② By rotating the turntable 103 around the slider assembly 102, the turntable 103 drives the main scale 104 and the moving pointer 105 to be adjusted to a horizontal / vertical state (i.e., parallel / perpendicular to the ground). During the rotation process, the limit balls 1023 connected to the compression springs 1022 first retract and then extend to complete the limit of the turntable 103.
[0029] ③ By sliding the main scale 104 on the turntable guide rail of 103, the main scale 104 drives the moving pointer 105 to adjust the displacement, and the fixed pointer at the end of the main scale 104 contacts the workpiece to be measured.
[0030] ④ Push the gap measuring tool in the Y direction to allow the pointer at the end of the main scale to penetrate into the wheel cavity / under the chassis to increase the contact area of the pointer at the end of the main scale;
[0031] ⑤ The wheel eyelash clearance / ground clearance of the vehicle is measured by moving the pointer 105 to slide in the main scale 104 and contact the object to be measured;
[0032] ⑥ Since the main structure of the gap measuring tool is concentrated on one side of the base 100, two balancing blocks 101 are arranged on the opposite side of the base 100 to prevent the base 100 from tilting during the measurement process.
[0033] like Figure 5 and 6 As shown, measure the front / rear wheel arch clearance
[0034] 1. Place the base of the gap measuring tool 100 parallel to the direction of vehicle travel and on the outside of the wheel to be measured;
[0035] 2. Rotate the turntable 103 until the main scale 104 is horizontal (i.e. the main scale 104 and the moving pointer 105 are parallel to the ground). At this time, the two limiting balls 1023 of the slider assembly 102 are just embedded in the limiting holes 103 to complete the limiting;
[0036] 3. Slide and adjust the slider assembly 102 up and down (the nut 107 is not locked at this time) so that the main scale 104 and the wheel center to be measured are basically at the same height, and tighten the nut 107 to complete the height limit of the slider assembly 102;
[0037] 4. Adjust the pointer at the end of the main ruler 104 to contact the front / rear wheel arch, and push the gap measuring tool in the Y direction to allow the pointer at the end of the main ruler to enter the wheel cavity, thereby increasing the contact area between the pointer at the end of the main ruler and the wheel cover;
[0038] 5. Adjust the moving pointer 105 to press against the edge of the tire to complete the front / rear wheel arch clearance measurement.
[0039] like Figure 7 As shown, measure the upper wheel arch clearance
[0040] 1. Place the gap measuring tool base 100 longitudinally parallel to the direction of vehicle travel and on the outside of the wheel to be measured;
[0041] 2. Adjust the X-axis position of the measuring tool so that the vertical center line of the base 100 substantially coincides with the center of the wheel to be measured;
[0042] 3. Rotate the turntable 103 until the main scale 104 is vertical (i.e. the main scale 104 and the moving pointer 105 are perpendicular to the ground), and the pointer at the end of the main scale 104 is at the top. At this time, the two limiting balls 1023 of the slider assembly 102 are just embedded in the limiting holes of the turntable 103 to complete the limiting;
[0043] 4. Move the slider assembly 102 upward as needed (at this time, the nut 107 is not locked), lock the nut 107, and complete the height limit of the slider assembly 102.
[0044] 5. Move the pointer at the end of the main scale 104 upward until it touches the upper wheel arch, and push the gap measuring tool in the Y direction to make the pointer at the end of the main scale penetrate into the wheel cavity, increasing the contact area between the pointer at the end of the main scale and the wheel cover.
[0045] 6. Adjust the moving pointer 105 to press against the tire edge to complete the measurement of the gap of the upper wheel arch.
[0046] As Figure 8 shown, measure the ground clearance
[0047] 1. Place the base 100 of the gap measuring tool longitudinally parallel to the vehicle's traveling direction on the outside of the side skirt.
[0048] 2. Rotate the turntable 103 until the main scale 104 is vertical (that is, the main scale 104 and the moving pointer 105 are perpendicular to the ground), and the pointer at the end of the main scale 104 is above. At this time, the two limit balls 1023 of the slider assembly 102 just fit into the limit holes 103 to complete the limit.
[0049] 3. Move the slider assembly 102 downward as needed (at this time, the nut 107 is not locked), lock the nut 107, and complete the height limit of the slider assembly 102.
[0050] 4. Move the pointer at the end of the main scale 104 downward until it touches the ground, and push the gap measuring tool in the Y direction to make the pointer at the end of the main scale penetrate under the chassis.
[0051] 5. Adjust the moving pointer 105 to press against the battery pack (or other low-position structures) to complete the measurement of the ground clearance.
