A dial indicator 4 and a three-axis adjustment mechanism 5 for adjusting the position of the dial indicator 4 are arranged on the top of the base 1 on one side of the adjustable push block 3. A motor 7 and a motor lifting mechanism 8 for adjusting the height of the motor 7 are also arranged on the top of the base 1 on the other side of the adjustable push block 3. A roller 71 is arranged at the output end of the motor 7, and the roller 71 is located above the space between the stop block 2 and the adjustable push block 3. It is widely used for the runout test of automotive bearings and hardware screw rod assembly products. It has simple operation, can quickly switch different products for detection, high measurement stability, the speed of the motor 7 can be adjusted by a motor controller 9, the efficiency is 200% higher than manual measurement, high data accuracy, can be used for batch detection, and at the same time has the advantages of simple structure, light weight, low manufacturing cost and simple maintenance, meeting economic benefits and having broad application prospects.

[0022] Specifically, the three-axis adjustment mechanism 5 includes a translation guide rail 51. A support frame 52 is movably arranged on the top of the translation guide rail 51. A moving block 53 is movably sleeved on the support frame 52. A moving rod 54 is movably sleeved inside the moving block 53.

[0023] Specifically, a handle screw one 56 for locking the relative position between it and the translation guide rail 51 is movably arranged on one side of the bottom of the support frame 52. A handle screw two 57 for locking the relative position between it and the support frame 52 is movably arranged on one side of the moving block 53, and a handle screw three 58 for locking the relative position between it and the moving rod 54 is movably arranged on the other side.

[0024] Specifically, an installation hole 55 for installing the dial indicator 4 is arranged inside one end of the moving rod 54. A fixed seat 6 is fixedly arranged on the top of the base 1. A handle screw four 61 is movably arranged on one side of the fixed seat 6. One end of the handle screw four 61 penetrates to the other side of the fixed seat 6 and is movably connected to one side of the adjustable push block 3. The dial indicator 4 is installed through the installation hole 55. The left and right positions of the dial indicator 4 can be adjusted by moving the support frame 52, and after adjustment, it is locked by the handle screw one 56. By adjusting the moving block 53 up and down on the surface of the support frame 52, and after adjustment, it is locked by the handle screw two 57. By adjusting the moving rod 54 back and forth inside the moving block 53, the front and back positions of the dial indicator 4 can be adjusted, and after adjustment, it is locked by the watch screw three.

[0025] Specifically, at least two stabilizing rods 62 with one end movably passing through the inside of the fixed seat 6 are arranged on one side of the adjustable push block 3. The motor lifting mechanism 8 includes a lifting guide rail 81 fixedly arranged on the top of the base 1. A moving seat 82 is movably sleeved on the lifting guide rail 81. The motor 7 is arranged on one side of the moving seat 82. The arrangement of the stabilizing rods 62 ensures the stability of the adjustable push block 3. Turning the handle screw four 61 can drive the adjustable push block 3 to move.

[0026] Specifically, a lifting rod 83 is hinged to the top of the lifting guide rail 81. One end of the lifting rod 83 is hinged to a pull rod 84. The bottom end of the pull rod 84 is hinged to one side of the moving seat 82. Pressing the end of the lifting rod 83 away from the pull rod 84, the lifting rod 83 pulls up the moving seat 82 through the pull rod 84. The moving seat 82 drives the roller 71, the counterweight 85 and the motor 7 to rise. Releasing the lifting rod 83, the counterweight 85, the motor 7 and the roller 71 drop by gravity, so that the roller 71 contacts the measured shaft.

[0027] Specifically, a counterweight 85 is arranged on one side of the moving seat 82 to press down one end of the lifting rod 83, so that the other end of the lifting rod 83 lifts the moving seat 82 through the pull rod 84. The moving seat 82 drives the motor 7 and the roller 71 to rise. Place the special fixture between the stop block 2 and the adjustable push block 3. Turn the handle screw four 61 to control the movement of the adjustable push block 3 to press the special fixture tightly. Place the measured shaft into the inside of the special fixture. Release the lifting rod 83, so that the counterweight 85, the motor 7 and the roller 71 drop. The surface of the roller 71 contacts the measured shaft. Manually press the counterweight 85 gently to check whether the measured shaft will drop. Otherwise, it is necessary to increase the counterweight 85 to press the measured shaft tightly. Then move the dial indicator 4 up and down and back and forth so that the dial indicator 4 contacts the center of the measured shaft and pre-presses the probe head about 0.5 mm. Then lock it through the handle screw two 57 and the handle screw three 58. Then move the dial indicator 4 left and right. After moving to the specified measurement position of the measured shaft, lock the handle screw one 56. Then zero the dial indicator 4. Turn on the switch of the motor controller 9. The motor 7 drives the measured shaft to rotate through the roller 71. The value displayed by the dial indicator 4 after rotating one week is the shaft runout value.

[0028] Specifically, a motor controller 9 is further arranged on the top of the base 1. The motor controller 9 is used to control the rotation speed and start of the motor 7.

[0029] In summary, this shaft part runout measuring instrument is widely used in the runout test of automotive bearings and hardware screw rod assembly products. It is simple to operate, can quickly switch different products for detection, has high measurement stability, the speed of the motor 7 can be adjusted through the motor controller 9, has higher efficiency than manual measurement, high data accuracy, can be used for batch detection, and at the same time has the advantages of simple structure, light weight, low manufacturing cost and simple maintenance, which meets the economic benefits and has a broad application prospect.
