The working principle of the utility model is as follows: first, the jig height is preset, and the gear clamping bar 90 is installed without clamping the gear detection member. Loosening the upper top block 8031, loosening the adjusting knob 8027, adjusting the height to a proper position, tightening the adjusting knob 8027, adjusting the upper top roller adjusting screw 8033 and the pressing rod adjusting screw 8035 to a proper tightness, pressing the tail end of the pressing rod 8026, lifting the upper top roller 8025, inserting one end of the gear clamping rod 90, then tightening the upper top screw 8032, and fixing one end of the gear clamping rod 90.

The adjusting bolt 7073 is loosened, the gear clamping bar 90 is slid to a proper position, the spacer 7072 is lifted to a proper height, and the other end of the gear clamping bar 90 is mounted in the fixing hole 7081 of the support bearing housing 708. A spacer 7072 or a tight metal sheet is placed between the support bearing housing 708 and the support block 7071, and the height of the height adjustment assembly 707 and the main jig 80 are clamped at the left and right ends of the gear, and then the adjustment bolt 7073 is locked.

Since the contact surfaces of the support block 7071 and the bottom two positions of the support bearing seat 708 are small, and the axis of the support bearing seat 708 is offset by a certain distance relative to the center line of the contact surfaces, as shown in fig. 8 and 9, m is the contact surface of the gasket 7072 and one end of the support bearing seat 708; n is the contact surface of the gasket 7072 with the other end of the supporting bearing seat 708; o is the supporting bearing center line; p is the center line of the adjusting bolt 7073; the distance a between the axis of the support bearing housing 708 and the center line of the adjusting bolt 7073 is greater than the distance x between the spacer 7072 and the center line of the adjusting bolt 7073.

Therefore, when the number and the height of the gaskets 7072 or the tight metal sheets placed at the left end and the right end between the supporting bearing seat 708 and the supporting block 7071 are adjusted, the corresponding height of the supporting bearing seat 708 can be changed in an enlarged or reduced manner, so that the height adjustment is more convenient and accurate, the height alignment of the two ends of the gear clamping rod 90 is facilitated, and the detection efficiency is improved.

The three-dimensional table 5 is fixed on the marble plane, and the heights of the left and right ends of the calibration gear clamping bar 90 are measured so as to be flush. The parallelism of the center line of the clamp shaft and the horizontal plane is measured and detected at the position of the gear clamping rod 90, so that the accumulated horizontal error of the structure is detected, and the machining precision requirements of the parts such as the base connecting plate 601, the supporting seat 602 and the like supported below are reduced.

Then, the horizontal plane angle is adjusted, and the device can detect the cylindrical line gear, the conical line gear and the plane line gear. The rotation angles of the horizontal plane are respectively corresponding to 0 degrees, alpha degrees (0 < alpha < 90 degrees) and 90 degrees, namely, the measuring head 104 is kept perpendicular to the spiral surface where the line of contact of the linear gear is located.

The drive motor moves the y-axis until the gauge head 104 contacts the gear clamp bar 90, and the drive motor moves the x-axis, translating the gauge head 104 in the x-axis direction. If the sensor 102 readings change, the first trimming kilohead 704 and the second trimming kilohead 706 are rotated to rotate the adjustable plate 702 to the appropriate angle to effect trimming of the angle.
