Description

Technical Field

[0002] In the process of detecting the geometric dimensions and form and position deviations of metal workpieces, the application of detection tooling is indispensable, which is the basic guarantee for achieving accurate detection. Generally speaking, when using a three-dimensional coordinate measuring machine to detect the geometric dimensions and form and position deviations of metal workpieces, there are certain restrictions on the measurement posture of the metal workpiece, which usually requires the metal workpiece to be fixed, the measured surface to be easy to collect, and not to interfere with the operation of the measuring mechanism.

[0003] In special cases, when the workpiece to be measured is a thin-walled product with a light weight and small volume, using a clamping fixture to fix the workpiece is likely to cause deformation, thereby affecting the quality assessment of the actual product; or when the workpiece to be measured is a product with a relatively complex appearance and structure, using a clamping fixture to fix the workpiece is likely to interfere with the operation of the measuring mechanism. Utility Model Content

[0004] The purpose of the utility model is to provide a magnetic adsorption detection fixture for metal workpieces, so that it can solve the problem that the existing thin-walled workpieces and products with complex external structures are not suitable for fixing with clamping fixtures during the detection process of geometric dimensions and form and position deviations.

[0005] The present invention adopts the following technical solutions to achieve the above-mentioned purpose:

[0006] A magnetic adsorption detection tool for metal workpieces, the magnetic adsorption detection tool having a stepped cylinder consisting of an upper cylinder and a lower cylinder; the diameter and height of the upper cylinder are smaller than the diameter and height of the lower cylinder; the upper end surface of the upper cylinder is provided with a plurality of blind holes evenly distributed along the circumference; the plurality of blind holes of the upper cylinder are all embedded with magnet blocks, and the upper surface of the magnet blocks is flush with the upper end surface of the upper cylinder.

[0007] The magnetic pole directions of the plurality of magnet blocks are consistent.

[0008] The utility model proposes a magnetic adsorption detection tool for metal workpieces, which adopts the above technical solution and has the following beneficial effects:

[0009] 1) The utility model utilizes the magnetic force of the magnet block to solve the problem that a thin-walled workpiece is easily deformed when a clamping fixture is used to fix it.

[0010] 2) The present invention solves the problem that the use of clamping fixtures to fix workpieces with complex external structures easily interferes with the operation of the measuring mechanism through the above-mentioned simple structure and magnetic adsorption method; the detection fixture of the present invention has a simple structure, is easy to manufacture and easy to implement.
