[0029] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below according to specific implementation methods and in combination with the accompanying drawings.

[0030] Figure 1 The schematic diagram of the structure of the measuring tool for measuring the length of the cavity bottom section by the end face tooth shape provided in the embodiment of the present application. The device comprises a base 1, a column 2, a movable guide rail 3, a movable seat 4, a driving device 5, a dial indicator 6 and a measuring calibration block 7. The dial indicator 6 is zeroed by the measuring calibration block 7, and then the workpiece 10 to be measured is measured, and it can be judged whether the difference is within the threshold range to determine whether the workpiece 10 to be measured meets the standard.

[0031] Specifically, the column 2 is fixedly mounted on the base 1 and arranged in the vertical direction. A movable guide rail 3 is fixedly mounted on the column 2, and the movable guide rail 3 extends along the length direction of the column 2, that is, the movable guide rail 3 extends in the vertical direction. The movable seat 4 is movably arranged on the movable guide rail 3, and the movable guide rail 3 can move, that is, rise and fall vertically. The dial indicator 6 is fixedly mounted on the movable seat 4 and moves synchronously with the movable seat 4.

[0032] The driving device 5 is used to drive the moving seat 4 to move along the moving guide rail 3. In this embodiment, the driving device 5 includes an adjusting screw. It is understandable that other forms of driving devices 5, such as servo cylinders and other components, can also be used.

[0033] Better, see Figure 1 A workpiece 10 seat 8 is fixedly installed on the base 1 just below the dial indicator 6. The workpiece 10 seat 8 is used to place the workpiece 10 to be tested. A plurality of support columns 9 are fixedly installed on the upper end of the workpiece 10 seat 8. The plurality of support columns 9 are evenly arranged on the upper end surface of the workpiece 10 seat 8 and are located at the edge of the upper end surface of the workpiece 10 seat 8, so that a groove for accommodating the lower end protrusion of the workpiece 10 is formed in the middle of the upper end surface of the workpiece 10 seat 8. See the cross-sectional view of the workpiece 10 Figure 3 .

[0034] In addition, the upper end of each support column 9 is configured to be spherical to prevent the sharp portion from causing damage to the workpiece 10 to be measured.

[0035] It should be noted that when the workpiece 10 to be measured is placed on the workpiece seat 8, the measuring pointer of the dial gauge 6 coincides with the axis of the workpiece 10, see Figure 1 .

[0036] The measurement calibration block 7 is designed and manufactured according to the drawing of the standard workpiece 10. Figure 5 and Figure 6The tooth surface of the measuring standard block is exactly the same as the tooth surface of the workpiece 10, and the distance between the tooth surface of the measuring calibration block 7 and its inner end surface (that is, the end surface in the groove in the middle of the upper end surface of the measuring calibration block 7) is equal to the distance between the tooth surface and the bottom of the cavity in the standard workpiece 10.

[0037] It should be noted that when the measuring calibration block 7 or the workpiece 10 to be measured is placed on the workpiece 10 seat 8 , the tooth surface faces the upper end surface of the workpiece 10 seat 8 .

[0038] When using the above-mentioned measuring tool for measuring the length of the cavity bottom section with the end face tooth profile, first place the measuring calibration block 7 on the workpiece 10 seat 8 with the tooth surface facing downward. Then, by controlling the moving seat 4 to descend, the dial indicator 6 moves downward until the measuring pointer of the dial indicator 6 is zeroed, and the current height of the moving seat 4 is recorded. Then, place the workpiece 10 to be measured on the workpiece 10 seat 8 with the tooth surface facing downward. Then control the moving seat 4 to move to the recorded height to check whether the current reading of the dial indicator 6 is less than the error threshold between the workpiece 10 to be measured and the standard workpiece 10. If less than, it means that the workpiece 10 to be measured is qualified; if greater than or equal to, it means that the workpiece 10 to be measured is unqualified.

[0039] Therefore, the technical solution of the present application solves the problem that three-coordinate measurement must be used when inspecting long sections of such products, greatly shortens the inspection time, and the equipment is easy to operate, does not require professional inspectors to operate the equipment, reduces production costs, and improves production efficiency.

[0040] In addition to the above embodiments, the present invention may also have other implementation modes; any technical solutions formed by equivalent replacement or equivalent transformation shall fall within the protection scope required by the present invention.
