[0042] like Figure 1 As shown, in some specific embodiments, the top assembly 4 may also include: a first hand wheel 42, which is arranged on the base plate 2 through a first hand wheel bracket, the first hand wheel 42 has a first screw 43 extending in the height direction; the top base 44 is threadedly connected to the first screw 43 to form a screw nut transmission structure, and the first top 41 is arranged on the top base 44.

[0043] In this way, as the first hand wheel 42 drives the first screw 43 to rotate, the center base 44 can move in the height direction because it is threadedly connected to the first screw, thereby driving the first center 41 to move in the height direction. When the first center descends, it can fit with the top of the honing head and cooperate with the positioning spindle box 7 to clamp the honing head.

[0044] In some more specific embodiments, the top assembly 4 may further include a support 45, the support 45 is disposed on the bottom plate 2, and the top base 44 is indirectly disposed on the bottom plate 2 through the support 45. A guide rod 46 parallel to the first screw rod 43 may be disposed on the support 45, the guide rod 46 passes through the top base 44 and is disposed on the support 45, and guides the top base to move along the height direction. In a specific embodiment, there may be two guide rods 46. Of course, in other embodiments, three, four or other numbers may be provided.

[0054] Step 300: operate the first hand wheel 42 to move the first tip 41 until the first tip 41 is in contact with the top of the sample rod, thereby clamping the sample rod 12;

[0055] Step 400: Rotate the sample rod 12 and adjust the position of the dial indicator 5 to calibrate the dial indicator 5;

[0056] Step 500: operate the first hand wheel 42 to move the first tip 41 upward to remove the sample rod;

[0057] Step 600: Positioning and clamping the honing head between the first center and the positioning spindle according to the process of installing the sample rod from step 100 to step 300;

[0058] Step 700: Read the reading of the dial gauge 5;

[0059] Step 800: The second center is fed in the height direction by operating the second hand wheel 81 of the feed tailstock 8, so that the honing head can be raised. By comparing and recording the readings of the dial indicator 5, the linear correlation between the radius change of the honing head and the linear movement of the second center can be measured.

[0060] In some more specific embodiments, the linear movement distance of the second top point can be read out by the scale set on the second hand wheel 81, which is a known structure in the prior art and will not be described in detail here.
