Embodiment Construction

[0040] The present invention will be further described below with reference to the drawings and embodiments.

[0041] The worm tooling in the worm gear transmission accuracy clinical detection device of the present invention is used for worm installation in the worm gear transmission accuracy detection, wherein the worm 10 is installed on the tooling, and the tooling is equipped with a worm angular displacement sensor for detecting the rotation angle of the worm 10 . As shown in Figure 1, the tooling has a bracket 16, a sliding plate 8 located above the bracket 16, and a pair of dead center one 111 and dead center two 112 for supporting both ends of the worm 10. The dead center one 111 is fixed on the bracket 16 The two ends of the dead center 112 are fixed on the skateboard 8. The two ends of the worm 10 to be tested are supported by dead center one 111 and dead center two 112 respectively. The skateboard 8 can slide to adjust the two dead center one 111 and dead center two. Th...

Abstract

The invention discloses an on-machine detection device of the worm gear pair transmission precision. The detection device comprises a rotary table for installing a worm gear and a tool for installing a worm, a worm gear angular displacement sensor which detects the rotation angle of the worm gear is installed in the rotary table, a worm angular displacement sensor which detects the rotation angle of the worm is installed on the tool, the worm gear angular displacement sensor and the worm angular displacement sensor are in output connection with a worm gear detector, the tool is provided with a bracket, a sliding plate located above the bracket and a pair of fixed centers for supporting the two ends of the worm, a driving motor is arranged on the bracket and drives a gear transmission set, and a rotor of the worm angular displacement sensor and a tail end gear coaxially and synchronously rotate to measure the rotation angel of the worm; the rotary table comprises an installation table and a base which can rotate relatively, a rotor of the worm gear angular displacement sensor is coaxially installed on a protruding column of the installation table, and a stator of the worm gear angular displacement sensor is fixedly connected with the base. The invention further discloses an on-machine detection method of the worm gear pair transmission precision. By means of the on-machine detection device and detection method of the worm gear pair transmission precision, the on-machine detection problem of the worm gear pair transmission precision is solved.

Description

Technical field [0001] The invention relates to the field of worm gear pair detection, in particular to a clinical detection device and a detection method for worm gear pair transmission accuracy. Background technique [0002] The current general procedure for worm gear processing is: processing the worm on a worm gear processing machine (hobbing machine), processing the worm on a worm grinder, and then grinding the worm gear and worm on a special worm gear inspector to grind the contact surface to detect the transmission accuracy and pitch difference Wait. [0003] For example, the worm gear meshing instrument disclosed in CN 102435432 A uses a second-hand gear hobbing machine to detect the meshing status of large worm wheels and worms. It includes a second-hand gear hobbing machine. The worm tooling is installed on the large flange of the second-hand gear hobbing machine. The hobbing machine is located on the base and positioned by the axis. Although this technical solution can...
