Embodiment Construction

[0014] Combine below figure 1 , the present invention will be described in further detail.

[0015] The indexing accuracy measuring device is composed of two parts: the measured mechanism and the detection mechanism;

[0016] The tested mechanism is composed of the tested block bracket 2 , the metal tested block 4 and the chuck, wherein the chuck can be designed as a G-shaped clip 3 . The tested block bracket 2 is fixed on the workpiece trough of each station according to the design of the turntable structure of the indexing mechanism. The metal tested block 4 is clamped and installed by the G-shaped clamp 3 and the tested block bracket 2, and the metal tested block The error of block 4 in the measurement direction is controlled within an acceptable range.

[0017] The detection mechanism is composed of an eddy current sensor, a sensor bracket 6, a chassis 1, a DC power supply 7, and a multimeter 8, wherein the eddy current sensor includes an eddy current sensor probe 5 and ...

Abstract

The invention discloses an indexing accuracy measuring device, which comprises a detected mechanism and a detection mechanism, wherein the detected mechanism is fixedly arranged on an indexing mechanism and comprises a detected block support and a metallic detected block, wherein the metallic detected block is fixedly arranged on the detected block support; and the detection mechanism comprises an eddy current sensor probe, a sensor support and a detection circuit, wherein the eddy current sensor probe is fixedly on the sensor support and is placed adjacent to the metallic detected block, and the eddy current sensor probe is connected with the detection circuit and is used for measuring the distance between the eddy current sensor probe and the metallic detected block. The indexing accuracy measuring device is designed aiming at detecting the indexing accuracy of an indexing device. By changing the design of the detected block support, the accuracy is guaranteed and the indexing accuracy of the indexing device can be conveniently and directly detected at the same time.

Description

technical field [0001] The invention relates to a device for measuring indexing accuracy, in particular to a device for measuring the indexing accuracy of a turntable of an indexing mechanism. Background technique [0002] With the continuous improvement of industrial automation, most factories currently use automation equipment in the manufacturing process to improve the accuracy of processing and assembly. Among the many automation equipment in the factory, the multi-station turntable device is widely used. The multi-station turntable mostly uses mechanical mechanisms to complete the intermittent indexing. At present, there are many types of intermittent motion mechanisms commonly used, such as ratchet mechanisms and groove wheel mechanisms. , Escapement mechanism, incomplete gear mechanism and space cam mechanism, etc. The positioning accuracy of these traditional mechanical turntables is greatly affected by the machining accuracy of groove wheels, ratchets, and cams, an...
