[0002] The front axle is an important part of the chassis system of a truck and a bus, is heavy (33-140kg) and long (1200-2100mm in unfolded length), has a complex shape, has many changes in the longitudinal section of the forging, has a large height difference in some parts, and the size of the ball head at both ends of the forging has many angle changes relative to the position of the spring seat and the I-beam, and the forging will have a deformation and warping phenomenon after heat treatment.

[0003] Therefore, a cold correction process must be arranged to ensure that each forging meets the requirements of the drawing and meets the subsequent processing, and after cold correction, each forging needs to be detected, and due to the fact that the forging is heavy and long, complex, and has many changes in the section and space size, it is difficult to meet the production needs by using conventional means for detection, such as three-coordinate detection, which is not suitable for batch detection due to special requirements of equipment and use environment, so a special gauge for detection is needed to meet the production needs on site.

[0004] Therefore, in order to improve the production rate and improve the production efficiency, the present design provides a special gauge for quickly detecting the shape and size of the automobile front axle. CONTENT OF THE UTILITY MODEL

[0005] The utility model aims at providing a special gauge for quickly detecting the shape and size of the automobile front axle.

[0014] The present invention will be further described clearly and completely below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited thereto.

[0015] according to Figure 1 and Figure 2 As shown, a special inspection tool for quickly detecting the shape and size of a car front axle includes: a base 1, a left limiting block 2, an inclined support block 3, a right limiting block 4, a double-axis slider 5, a slider baffle 6, and a forging 7. The base 1 has a U-shaped cross-section. The left limiting block 2 and the double-axis slider 5 are respectively installed at the left and right ends of the base 1. The inclined support block 3 is installed in the middle part of the base. The right limiting block 4 is installed on the upper surface of the double-axis slider 5. The slider baffle 6 is installed at the edge of the double-axis slider 5. The forging 7 is installed between the left limiting block 2 and the right limiting block 4.

[0016] Specifically, the left limiting block 2 and the right limiting block 4 have a "V" shaped structure.

[0017] Specifically, there are four inclined support blocks 3 installed symmetrically, and the inclined support block 3 has an "L" shape structure.

[0018] During operation, first, pull the right limiting block 4 to the right and place the forging 7 into the inspection fixture with the ball end of the forging facing upwards. Place it into the "V"-shaped cavity of the left limiting block 2, with the four spring surfaces of the forging 7 in contact with the inclined support block 3. Push the double-axis slider 5 and move the right limiting block 4 to the left, placing the ball end of the forging into the "V"-shaped cavity of the right limiting block 4. Then, check whether the ball end fits snugly against the limiting block, whether the contour of the upper opening of the V-shape coincides with the contour of the ball end face, check whether the gap on both sides of the spring plate is uniform with a feeler gauge, check whether the spring plate fits snugly against the inclined support block, and measure the total length of the front axle with a ruler. After the above steps, the inspection of one forging is completed.
