Description

Technical Field

[0001] The utility model mainly relates to the technical field of end face toothed discs, in particular to a device for calibrating a reference axis of an end face toothed disc. Background Art

[0002] The end face gear mainly provides a high-precision angle reference for the inertial group and inertial group devices. The inertial group and inertial group devices need to be tested in multiple postures. For example, the horizontal end face gear can meet the testing requirements of multiple postures. To meet the testing requirements of multiple postures, its lifting axis needs to adopt a beadlock shaft system. In order to achieve high-precision rotation, the rotating axis of the beadlock shaft system must be highly coincident with the virtual axis of the end face gear. Because the beadlock shaft system serves as a support, it can achieve smooth rotation and engagement of the end face gear in a lying posture. Therefore, the accuracy of the beadlock shaft system needs to be ensured. The existing technology lacks a reference calibration before processing, and can only be tested after the outer side is processed. Utility Model Content

[0018] The present invention will be further described below in conjunction with specific embodiments. The present invention is explained through the exemplary embodiments and descriptions of the present invention, but is not intended to limit the present invention.

[0019] Example: Figure 1-Figure 3 The end face toothed disc reference axis calibration device shown includes an upper toothed disc 1 and a lower toothed disc 2. The upper toothed disc 1 and the lower toothed disc 2 are arranged on a jig 3. The jig 3 can separate or engage the upper toothed disc 1 and the lower toothed disc 2. The upper toothed disc 1 and the lower toothed disc 2 are provided with a center hole. A core shaft 4 is provided in the center hole of the upper toothed disc 1. The core shaft 4 and the pressure plate 5 are fixed with a hexagonal screw 7.

[0020] A standard ring gauge 6 is provided on the upper gear disc 1 , the center hole of the standard ring gauge 6 coincides with the center holes of the upper gear disc 1 and the lower gear disc 2 , and a clock-type dial indicator is provided on the center hole wall of the standard ring gauge 6 .

[0021] A lifting mechanism is provided on the jig 3 , the lower toothed disc 2 is fixed to the jig 3 , the fixing surfaces of the lower toothed disc 2 and the jig 3 are parallel, and the jig 3 lifts and lowers the upper toothed disc 1 .

[0022] A threaded hole is provided in the mold 3 , and the core shaft 4 is threadedly connected to the threaded hole of the mold 3 .

[0023] The core shaft 4 is rotatably connected to the upper gear disc 1 in the center hole of the upper gear disc 1. After the core shaft 4 lifts up the upper gear disc 1, the upper gear disc 1 can rotate freely, and the pressure plate 5 is rotatably connected to the upper gear disc 1.

[0024] The center hole of the standard ring gauge 6 is a standard circle.

[0025] The minimum graduation value of the bell-type dial indicator is 0.01mm, and the bell-type dial indicator is used to calibrate the standard ring gauge 6.

[0026] Glue is also provided at the contact surface between the standard ring gauge 6 and the upper toothed disc 1. The glue is applied in batches using iron wire, and the glue is used to remember the calibration position.

[0027] The working principle of the utility model is as follows: the standard ring gauge 6 is placed above the upper gear plate 1, and the head of the clock-type dial indicator touches the inner wall of the center hole of the standard ring gauge 6. The clock-type dial indicator has the advantages of high precision, sensitive head and strong operability, and the minimum graduation value is 0.01mm. Then start to calibrate the standard ring gauge 6.

[0028] When starting to calibrate the standard ring gauge 6, reset the dial indicator to zero, then lift the upper gear disc 1 and disengage it from the lower gear disc 2. When the upper gear disc 1 is rotated to about 180°, the upper gear disc 1 and the lower gear disc 2 are engaged. After engagement, observe the dial indicator value. If the value is no longer at zero, lightly tap the standard ring gauge 6 to return the dial indicator value to zero, then rotate it to 90° and 270° positions in turn, and repeat the above steps to return the dial indicator to zero.

[0029] After the calibration is completed, drop a small amount of 502 glue from the pressure plate onto the iron wire, then place a small amount of glue on the iron wire at the joint between the standard ring gauge 6 and the upper toothed disc 1, and drip 502 glue in this way at the positions of 0°, 180°, 90°, and 270° in turn. The calibration can be completed after the glue solidifies. The reason for a small amount is that if the entire drop is dripped into the joint, the surface tension when the glue solidifies will cause the adjusted standard ring gauge 6 to shift.

[0030] The center hole of the calibrated standard ring gauge 6 is coaxial with the virtual axis of the gear pair, and then this standard ring gauge 6 can be used as the processing reference of the gear bead shaft system.

[0031] Any matters not described in this utility model are applicable to the prior art.
