[0055] like Figures 1 to 8 As shown, this utility model discloses a control arm bushing press-fit height detection device, which includes a zeroing base plate 10, a mounting base 20, a positioning component, a connecting member 30, and a digital dial indicator 40. The zeroing base plate 10 has a first positioning hole 11, and the mounting base 20 has a second positioning hole 21. The positioning component passes through the second positioning hole 21 and is installed into the first positioning hole 11, thus positioning the mounting base 20 on the zeroing base plate 10. One end of the mounting base 20 has a through mounting hole 22, and the digital dial indicator 40 is installed in the mounting hole 22 via the connecting member 30, with the pin 41 of the digital dial indicator 40 maintaining contact with the zeroing base plate 10.
[0056] Preferably, the positioning assembly includes a positioning pin 50 and a grip 51. The positioning pin 50 is installed in the first positioning hole 11, and the grip 51 passes through the second positioning hole 21, and the grip 51 is connected to the positioning pin 50.
[0057] More preferably, the connector 30 is a connecting pin, which is installed in the mounting hole 22, and the digital dial indicator 40 is fixed in the mounting hole 22 by the connecting pin.
[0058] Furthermore, multiple support feet 23 are provided at the bottom of the card holder 20, and the support feet 23 are in contact with the zeroing base plate 10. The support feet 23 extend downward along the outer wall of the card holder 20.
[0059] like Figure 3 As shown, the card holder 20 includes a positioning portion 24 and a connecting portion 25 that are connected to each other. The mounting hole 22 is installed on the connecting portion 25. The positioning portion 24 is circular.
[0060] For example, in this embodiment, the bottom of the card holder 20 is provided with three support feet 23, which are evenly arranged along the outer wall of the positioning portion 24. The ends of the support feet 23 are preferably arc-shaped. The bottoms of the multiple support feet 23 are flush and located on the same plane.
[0061] like Figure 4 As shown, the zero base plate 10 includes a first base plate 12 and a second base plate 13 connected in a stepped manner, with the height of the first base plate 12 being higher than the height of the second base plate 13. The support foot 23 is in contact with the first base plate 12, and the pin 41 of the digital dial indicator 40 is in contact with the second base plate 12.

[0065] Then, connect the connecting pin (i.e., connector 30) and the digital dial indicator 40 through the mounting bracket 20 according to... Figure 1 Assemble according to the style.
[0066] Finally, the entire testing device is placed on the zero-base plate 10 to complete the assembly.
[0067] After the digital dial indicator 40 is powered on, its pin 41 contacts the zeroing base plate 10 to perform zeroing and reset. After the value is displayed as zero, subsequent operations can be performed.
[0068] like Figure 2 As shown, before detecting the bushing pressing height of the workpiece being tested, the digital dial indicator 40 is first inserted into the mounting hole 22 of the card holder 20, and the pin of the digital dial indicator 40 is kept in contact with the zeroing base plate 10.
[0069] At this point, turn on the power switch of the digital dial indicator 40 and press the zeroing button to reset it to zero. When the value displayed on the screen of the digital dial indicator 40 is 0, the reset to zeroing is complete.
[0070] Then remove the testing device, and use the lever 51 to align the positioning pin 50 with the center hole of the bushing 100 inserted into the workpiece, so that the three-jaw mechanism on the chuck 20 contacts the top end face of the bushing.
[0071] At this time, the ejector pin below the digital dial indicator 40 will automatically fall onto the black end face of the workpiece being measured. At the same time, observe the value displayed on the screen of the digital dial indicator 40, which is the desired bushing pressing height value.
