A dial indicator 4 is installed on the measuring cover 3. The dial indicator 4 cooperates with the top surface of the boss 2 to form a measuring structure for measuring the height of the mounting end face of the bevel gear.

[0029] Specifically, workpiece 5 is a bevel gear, and workpiece 5 is positioned by the upper part of base 1; the top surface of boss 2 is the reference surface for measurement; when installing standard workpiece 5, the dial indicator 42 can contact the top surface of boss 2, at which time the top surface of standard workpiece 5 is the mounting end face of standard bevel gear; boss 2 is installed in the middle of base 1, and the upper part of boss 2 extends into shaft hole 11.

[0030] Among them, reference Figure 1 and Figure 2 In this embodiment, the upper part of the base 1 is provided with a standard conical die 7 with the same design parameters as the workpiece 5 to be tested.

[0031] Specifically, the upper part of the base 1 is machined with a standard bevel tooth die 7 according to the meshing area of ​​the workpiece 5, so that the tooth shape of the standard bevel tooth die 7 can fit with the tooth shape of the workpiece 5 to position the workpiece 5.

[0032] Reference Figure 1 and Figure 2In this embodiment, the base 1 is provided with a mounting groove 6, and the lower part of the boss 2 is installed in the mounting groove 6.

[0033] Specifically, the lower part of the boss 2 is connected to the mounting groove 6 by welding.

[0034] Reference Figure 1 and Figure 4 In this embodiment, the measuring cover 3 is provided with a vertical hole 8, and the dial indicator 44's stem 41 is inserted into the vertical hole 8.

[0035] Specifically, the dial indicator 4 has a vertical hole 8 extending from its head 42, meaning that the head 42 of the dial indicator 4 is exposed at the bottom of the measuring cover 3.

[0036] Reference Figure 1 and Figure 4 In this embodiment, the measuring cover 3 includes a cover plate 31, an upper protrusion 32 is installed on the top of the cover plate 31, and a lower protrusion 33 is installed on the bottom of the cover plate 31. The lower protrusion 33 can be inserted into the shaft hole 11.

[0037] Specifically, the cover plate 31, the upper boss 32, and the lower boss 33 are designed as a single unit; the vertical hole 8 passes through the cover plate 31, the upper boss 32, and the lower boss 33; both the upper boss 32 and the lower boss 33 are cylindrical; the lower boss 33 is located directly above the boss 2; by inserting the lower boss 33 into the shaft hole 11, the measuring cover 3 is positioned on the workpiece 5; the diameter of the lower boss 33 is the same as the diameter of the shaft hole 11; the top surface of the standard workpiece 5 is located below the bottom surface of the cover plate 31.

[0038] Reference Figure 1 and Figure 4 In this embodiment, the upper protrusion 32 is provided with a horizontal hole 9 communicating with the vertical hole 8, and a fastening screw 10 for locking the dial indicator 4 stem 41 is installed in the horizontal hole 9.

[0039] Specifically, the horizontal hole 9 is a threaded hole, and the fastening screw 10 is threadedly connected to the horizontal hole 9.

[0040] Reference Figure 1 In this embodiment, the axis of the shaft hole 11, the axis of the boss 2, the axis of the measuring cover 3, and the axis of the dial indicator 4 rod 41 are all the same axis, which makes the measurement results accurate.

[0041] In summary, during use, first place the standard workpiece 5 into the standard bevel gear die 7, then place the measuring cover 3 on the standard workpiece 5, so that the dial indicator 4's head 42 contacts the top surface of the boss 2. Secure the dial indicator 4's stem 41 with the fastening screw 10, and rotate the dial to zero. During measurement, remove the zeroed dial indicator 4 along with the measuring cover 3, then remove the standard workpiece 5, replace it with the workpiece to be measured, and use the zeroed dial indicator 4 along with the measuring cover 3 for measurement. The value at which the dial indicator 4's pointer deviates from zero is the workpiece's error value. If the error is within the permissible range, it is a qualified product; otherwise, it is a defective product. This invention ensures the consistency of the bevel gear mounting end face height with the standard bevel gear, effectively solving the problems of low measurement efficiency and inaccurate measurement results.

[0042] This invention enables quantitative measurement with high efficiency.
