Description

Technical Field

[0001] The utility model belongs to the technical field of detection fixtures, and in particular relates to a clamping device used for part surface detection. Background Art

[0002] Parts testing refers to testing the parts assembly accuracy, surface quality, material mechanical properties and hidden defects to ensure the qualification of the parts. During the parts testing process, some irregular parts need to be fixed with a clamping mechanism to facilitate various aspects of the parts testing.

[0003] During use, the clamping mechanism squeezes and limits the required inspection parts through the limit plate, and then performs multi-directional inspection on the parts. However, the existing clamping mechanism cannot be adjusted to a suitable clamping method according to the shape of the parts, and fixed adjustment mechanisms need to be set in multiple directions to achieve clamping, which makes adjustment more cumbersome.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0012] The utility model clamps parts by using a mobile clamping mechanism with multiple elastic clamping blocks. When the elastic clamping blocks with corresponding shapes and thicknesses of the parts are pressed down, the parts can be clamped and fixed in both horizontal and vertical directions, thus achieving a clamping effect of fixing two directions with one mechanism. When used in conjunction with a motor, the clamping adjustment is faster and more convenient. BRIEF DESCRIPTION OF THE DRAWINGS
