Problems solved by technology

When the radial size of the workpiece is small, the plasticine will block the light of the projector and cannot be used; not only that, because the radial size of the workpiece is small and the axial size is large, it is not stable to use plasticine to fix
If you use side clamping, it will not only block the light, but also make it difficult to ensure that the workpiece is upright

Abstract

The invention relates to an upper-pressing projection detection tool suitable for eccentric shaft workpieces. The technical solution adopted is: comprising a glass table, an upper light source, a lower light source and a fixing device. The fixing device includes a magnetic base, a connecting rod, A top, a magnet or an electromagnet is arranged on the top of the magnetic base, one end of the connecting rod is adsorbed on the top surface of the magnetic base, and the other end is connected to the top. The top surface of the magnetic seat is a step surface, and each step top surface is respectively provided with a magnet or an electromagnet. In the present invention, the magnetic base absorbs the connecting rod to press the workpiece, and applies pressure from the top of the workpiece to ensure that the workpiece is upright. Compared with the middle part or the bottom, the required force is the smallest, and the magnetic base can be made into steps according to needs to adapt to different heights. Components.

Description

technical field [0001] The invention relates to a detection tool, in particular to an upward-pressing projection detection tool suitable for eccentric shaft processing parts. Background technique [0002] Using a projector to project shafts from the axial direction has high efficiency and is easy to obtain the cross-sectional profile. When testing, the shaft needs to be erected on the glass table of the projector and fixed, especially when it is necessary to use a probe to establish the coordinates of the workpiece inspection. The workpiece must be fixed. The traditional workpiece fixing method on the projector is to use plasticine, and pile up the plasticine at the bottom of the workpiece standing on the working table of the projector to fix it. When the radial size of the workpiece is small, the plasticine will block the light of the projector and cannot be used; not only that, but because the radial size of the workpiece is small and the axial size is large, it is not st...
