[0015] The present invention will be described in further detail below with reference to specific embodiments and accompanying drawings.

[0016] A kind of Figure 1-4The left steering knuckle comprehensive measuring tool shown includes a fixture base plate 2 and a support leg 1, wherein the support leg 1 is arranged at the four corners of the bottom surface of the fixture base plate 2 so that the top surface of the fixture base plate 2 is a horizontal plane. A positioning sleeve 3 is provided in the middle of the fixture base plate 2 for positioning the shaft of the left steering knuckle. A bracket hole positioning bushing 23 corresponding to one of the bracket holes of the left steering knuckle is provided on the fixture base plate 2, and the positioning bushing 23 is embedded in the fixture base plate 2. A bracket hole positioning hole pin 6 is provided in the bracket hole positioning bushing 23, so that the left steering knuckle can be completely positioned by two pins on one side. The left steering knuckle uses one bracket hole to position the other bracket hole that needs to be measured, so a bracket hole bushing 5 corresponding to the other bracket hole of the left steering knuckle is provided on the fixture base plate 2, and a bracket hole pin 4 is provided in the bracket hole bushing 5. The position of the bracket hole is determined by judging whether the bracket hole pin 4 can be smoothly inserted into the bracket hole bushing 5.

[0017] An ABS hole bushing 16 and an ABS mounting hole bushing 18 are arranged adjacent to each other on the right side of the locating sleeve 3, wherein an ABS hole plug 15 is provided in the ABS hole bushing 16, and an ABS mounting hole plug 17 is provided in the ABS mounting hole bushing 18. After the left steering knuckle is positioned, the ABS hole plug 15 is inserted into the ABS hole bushing 16, and the ABS mounting hole plug 17 is inserted into the ABS mounting hole bushing 18 to detect whether the position of the holes is qualified. Handles are provided on the upper ends of the ABS hole plug 15 and the ABS mounting hole plug 17.

[0018] An ABS end face height gauge 24 is installed on the top surface of the fixture base plate 2. This I-shaped gauge has an I-shaped lower end surface that serves as a reference surface for contact with the top surface of the fixture base plate 2. The lower end surfaces of the left and right pieces serve as the minimum and maximum dimension detection surfaces, respectively. The gauge determines whether the end face height is within the minimum and maximum dimensions to determine if the end face height meets the minimum and maximum dimensions.

[0019] A kingpin hole measuring mechanism is also provided on the fixture base plate 2. The kingpin hole measuring mechanism includes a kingpin hole seat 11 provided on the fixture base plate 2. A horizontally arranged kingpin hole bushing 13 is provided on the kingpin hole seat 11. The axial direction of the kingpin hole bushing 13 deviates 4mm to the right. A kingpin hole plug 12 is provided in a sliding fit within the kingpin hole bushing 13. By judging whether the kingpin hole plug 12 can be smoothly inserted into the kingpin hole bushing 13, it is judged whether the position of the kingpin hole meets the requirements. A kingpin hole end face feeler gauge 14 is movably provided on the end face of the kingpin hole bushing 13. The kingpin hole end face feeler gauge 14 has a through and stop end. By judging whether the through end of the kingpin hole end face feeler gauge 14 can be inserted into the gap between the end face of the kingpin hole bushing 13 and the end face of the kingpin hole, and if the stop end cannot be inserted, the end face size is qualified.

[0020] The steering hole measuring mechanism includes a steering hole seat 19 provided on the fixture base plate 2. A horizontally arranged steering hole bushing 21 is provided on the steering hole seat 19. The axial direction of the steering hole bushing 21 is parallel to the axial direction of the kingpin hole bushing 13. The spacing between the steering hole bushing 21 and the kingpin hole bushing 13 is 118.6 mm. A steering hole plug 20 is provided in a sliding fit within the steering hole bushing 21. Since the steering hole is a tapered hole, a taper sleeve 22 is connected to the front end of the steering hole plug 20 in this embodiment. During testing, the taper sleeve 22 is pre-fitted into the steering hole. By horizontally moving the steering hole plug 20 to determine whether it can be successfully inserted into the center hole of the taper sleeve 22, it can be determined whether the steering hole position meets the requirements.

[0021] The shock-absorbing hole measuring mechanism includes a shock-absorbing hole seat 7 provided on the fixture bottom plate 2, and two parallel shock-absorbing hole bushings 9 are provided on the shock-absorbing hole seat 7, wherein the horizontal height of the shock-absorbing hole bushing at the outer end is higher than that of the inner shock-absorbing hole bushing 9. A shock-absorbing hole plug 8 is provided in a sliding fit in each shock-absorbing hole bushing 9. By horizontally moving the shock-absorbing hole plug, it is judged whether it can be smoothly inserted into the shock-absorbing hole to judge whether the position of the shock-absorbing hole meets the requirements. In addition, a shock-absorbing hole end face feeler gauge 10 is movably provided on the end face of the shock-absorbing hole bushing 9. Similarly, by judging that the through end of the shock-absorbing hole end face feeler gauge 10 can be smoothly inserted into the gap between the end face of the shock-absorbing hole bushing 9 and the end face of the shock-absorbing hole, and the stop end cannot be inserted into the gap, the size of the shock-absorbing hole end face meets the requirements.
