Detailed Description

In order that the utility model may be more readily understood, a more particular description thereof will be rendered by reference to specific embodiments that are illustrated in the appended drawings.

Fig. 1 is a schematic structural diagram of a measuring tool for measuring the length of a cavity bottom section by using an end face tooth form according to an embodiment of the present application. The device comprises a base 1, an upright post 2, a movable guide rail 3, a movable seat 4, a driving device 5, a dial indicator 6 and a measurement calibration block 7. The dial indicator 6 is calibrated by the measurement calibration block 7, then the workpiece 10 to be measured is measured, and whether the difference is within the threshold range is determined, so that whether the workpiece 10 to be measured meets the standard can be determined.

Specifically, the upright post 2 is fixedly installed on the base 1 and is arranged along the vertical direction. A moving rail 3 is fixedly mounted on the upright 2, and the moving rail 3 extends along the length direction of the upright 2, i.e., the moving rail 3 extends in the vertical direction. The movable seat 4 is movably disposed on the movable rail 3, and the movable rail 3 is moved, i.e., vertically lifted. The dial indicator 6 is fixedly arranged on the movable seat 4 and synchronously moves along with the movable seat 4.

The driving device 5 is used for driving the movable seat 4 to move along the movable guide rail 3. In the present embodiment, the drive means 5 comprise an adjusting screw. It will be appreciated that other forms of drive means 5 may be used, such as servo cylinders.

Preferably, referring to fig. 1, a workpiece 10 seat 8 is fixedly arranged on the base 1 right below the dial indicator 6. The workpiece 10 seat 8 is used for placing a workpiece 10 to be detected. A plurality of support columns 9 are fixedly arranged at the upper end of the workpiece 10 seat 8, and the support columns 9 are uniformly distributed on the upper end face of the workpiece 10 seat 8 and are positioned at the edge of the upper end face of the workpiece 10 seat 8, so that a groove for accommodating the protruding part at the lower end of the workpiece 10 is formed in the middle of the upper end face of the workpiece 10 seat 8. A cross-sectional view of the workpiece 10 is shown in fig. 3.

In addition, the upper end of each support column 9 is spherically shaped, so that damage to the workpiece 10 to be tested by the sharp part is avoided.

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

The measuring calibration block 7 is designed and manufactured according to the drawing of the standard workpiece 10. Referring to fig. 5 and 6, the tooth surface of the measurement standard block is identical to the tooth surface of the workpiece 10, and the distance between the tooth surface of the measurement standard block 7 and the inner end surface thereof (i.e., the end surface in the groove in the middle of the upper end surface of the measurement standard block 7) is equal to the distance between the tooth surface and the cavity bottom in the standard workpiece 10.

When the measurement 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.

When the measuring tool for the length of the cavity bottom section of the end face tooth form is used, the measuring calibration block 7 is firstly placed on the workpiece 10 seat 8, and the tooth face is downward. Then, the dial indicator 6 is moved down to zero by controlling the movable base 4 to descend, and the current height of the movable base 4 is recorded. The workpiece 10 to be measured is then placed on the workpiece 10 seat 8 with the tooth surface facing down. And then controlling the movable seat 4 to move to the recorded height, and checking whether the reading of the current dial indicator 6 is smaller than the error threshold between the workpiece 10 to be measured and the standard workpiece 10. If the value is smaller than the predetermined value, the workpiece 10 to be measured is qualified, and if the value is larger than or equal to the predetermined value, the workpiece 10 to be measured is not qualified.

Therefore, the technical scheme of the application solves the problem that three-coordinate measurement is needed for a long time of the detection section of the product, greatly shortens the detection time, has simple equipment operation, does not need professional detection personnel to operate the equipment, reduces the production cost and improves the production efficiency.

Other embodiments of the present utility model are possible in addition to the above embodiments, and all technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of the present utility model.
