Embodiment 1

[0045] Embodiment 1: a kind of concentricity automatic detection device, as Figure 1-3 As shown, it includes a flat base 13, on which a positioning seat 15 for positioning the DUT 1 is installed, the positioning seat 15 is in the shape of a vertical right-angle folding plate, and a pair of bearing seats 7 are also fixed on the base 13. A longer moving screw mandrel 9 is installed on the bearing block 7 through a pair of bearings, and one end of the moving screw mandrel 9 passes through one of the bearing blocks 7 and is connected with a moving servo motor 6 .

[0046] The moving screw mandrel 9 is parallel to the long side of the positioning seat 15, and the moving screw mandrel 9 is threadedly connected with a horizontal support plate 26 by the moving screw mandrel pair 10, and the supporting plate 26 is driven by the moving screw mandrel 9 for convenience. Translation, the base 13 is provided with a moving slide rail 8, the support plate 26 and the moving screw pair 10 are ...

Embodiment 2

[0057] Embodiment 2: The difference from Embodiment 1 is that the imaging device 27 is directly fixed on the base 13, and the focus position of its optimal imaging corresponds to the position of the hole to be measured. When the first imaging is performed, the coordinates of the hole to be measured are generated and guided Adjust the position of the measuring piece 16, and determine whether the measuring piece 16 is concentric with the hole to be measured during the second imaging, and perform corresponding actions according to the result, as described in Example 1.

Abstract

The invention discloses an automatic concentricity detection device and method, and the device comprises a measurement part which is connected with a drive assembly, and is driven by the drive assembly to be adjusted to a position concentric with a to-be-measured hole, a coordinate positioning assembly used for obtaining position coordinates of the to-be-measured hole so as to guide the driving assembly to move, and a control system used for recording the movement distances of the driving assembly in multiple directions and taking the movement distances as actual measurement coordinates of theto-be-measured hole. Through the arrangement, the coordinate positioning assembly is used for preliminarily positioning the to-be-measured hole, the driving assembly is guided to execute the action until the measuring piece and the to-be-measured hole are concentric, at the moment, the actual measurement coordinates are recorded through the control system, finally, the actual measurement coordinates of all the to-be-measured holes are compared and calculated, and accurate concentricity data can be obtained; and the automation degree is high, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of detection equipment, in particular to a concentricity automatic detection device and method. Background technique [0002] At present, the injection molding products and sheet metal products used in the home appliance industry have detection and control requirements for concentricity. The concentricity of product holes has a great impact on the assembly of the whole machine and after-sales installation and use. Problems such as running jitter and loose closure can easily lead to after-sales complaints. [0003] At present, the common detection method of concentricity of injection molding products and sheet metal products is manual. When it is necessary to measure the concentricity of multiple holes on a certain workpiece, the fixture is first used to align the two ends of the workpiece to be measured. The hole is fixed, and then the hole position in the middle is measured with a pass gauge. The differenc...
