Embodiment 1

[0050] see Figure 1-9 , a worm gear meshing detection device, including a worm gear positioning cylinder 7 and a worm clamping mechanism, the worm gear positioning cylinder 7 is fixedly connected to a linear slide 3, and the linear slide 3 and the worm clamping mechanism are fixedly installed on a workbench 1 The measured worm gear is set on the worm gear positioning cylinder 7, and the standard worm is clamped on the worm clamping mechanism, or the standard worm gear is set on the worm gear positioning cylinder 7, and the measured worm is clamped on the worm gear clamping mechanism.

[0051] Such as Figure 1-6 As shown, the linear slide table 3 includes a slide seat 301 fixedly connected to the workbench 1, the slide seat 301 is fixedly connected with a first slide rail 302, and the first slide rail 302 is slidably connected with a first slide table 303; A first air cylinder 304 is also fixedly installed on the 301, the output shaft of the first air cylinder 304 is connect...

Embodiment 2

[0078] Such as Figure 7-9 , Figure 5 As shown, the second embodiment is an improvement on the basis of the first embodiment, mainly to make the device applicable to the detection of the meshing of the spur gear and the worm, and to enhance its versatility. Therefore, an angle adjustment mechanism 16 is added, and the angle adjustment mechanism 16 includes a base 1601 fixedly installed on the workbench 1, the second servo motor 1602 is fixedly installed on the installation base 1601, the output shaft of the second servo motor 1602 is fixedly connected with the back side of the mounting plate 15, and the second servo motor 1602 The rotation of the output shaft of the second servo motor 1602 drives the mounting plate 15 to rotate, thereby changing the angle of the turbine clamping mechanism; when the angle of the output shaft of the second servo motor 1602 changes, the angle of the mounting plate 15 connected to it will also change, and finally the mounting plate 15. The angle...

Abstract

The invention relates to a worm gear and worm engagement detection device which comprises a worm gear positioning cylinder and a worm clamping mechanism, the worm gear positioning cylinder is fixedlyconnected to a linear sliding table, and the linear sliding table and the worm clamping mechanism are both fixedly installed on a workbench; a worm gear is arranged on the worm gear positioning cylinder, and a worm is arranged on the worm clamping mechanism; the device also includes an angle encoder which is used for detecting the meshing transmission ratio of the worm wheel and the worm, a seconddisplacement sensor which is used for detecting the radial run-out of the worm wheel, and a first displacement sensor which is used for detecting the meshing center of the worm wheel and the worm. According to the worm and gear engagement detection device, the angle encoder, the second displacement sensor and the first displacement sensor are used in cooperation, the meshing condition of the wormwheel and the worm is detected in three aspects of worm and worm wheel one-tooth meshing error and full-tooth meshing error detection, worm wheel and worm meshing maximum center distance detection, worm wheel and worm meshing minimum center distance detection, worm wheel and worm meshing radial run-out detection, the meshing condition is accurately reflected, and grouping is facilitated.

Description

technical field [0001] The invention relates to the technical field of automobile electric steering gear detection, in particular to a worm gear meshing detection device. Background technique [0002] Worm gears and worms in automobile electric steering gears are core components, and the processing precision of worm gears and worms is required to be high. Mass production and processing cannot guarantee the consistency of machining accuracy of parts. It is necessary to detect and group matched worm gears after processing. . [0003] The public document with the application publication number of CN 110160676 A discloses a worm gear meshing detection device, which includes a worm positioning mechanism, a worm translation mechanism, a worm positioning mechanism, a worm horizontal movement mechanism, a worm vertical movement mechanism, and a worm platform lock Tightening mechanism, worm mechanism support table mechanism, worm operating platform; it can detect the meshing of worm...
