Detailed Description
The present invention will be described in further detail with reference to the following drawings and specific embodiments.
As shown in fig. 1, the three-coordinate measuring platform with the positioning fixture includes a three-coordinate measuring platform body 1 and a positioning fixture 2 disposed on the three-coordinate measuring platform body 1, and the three XYZ directions of the positioning fixture 2 are disposed opposite to the three XYZ directions of the three-coordinate measuring platform body.
Referring to fig. 2, the positioning fixture 2 includes a bottom plate 3, a pressing plate 4 clamped around the bottom plate 3, and at least one set of positioning units 6, where each set of positioning units 6 includes a cushion block 8, a pair of supporting columns 7 symmetrically arranged on the lower surface of the cushion block 8, and a positioning pin 9 installed in the middle of the upper surface of the cushion block 8. One end of the pressing plate 4 is L-shaped and clamped at the edge of the bottom plate 3, and the other end of the pressing plate 4 is fixed on the surface of the three-coordinate measuring platform body 1 through bolts, so that the bottom plate 3 is fixedly arranged on the three-coordinate measuring platform body 1 through the pressing plate 4; meanwhile, a plurality of positioning holes 5 are formed in the surface of the bottom plate 3, the positioning holes 5 are arranged in an array mode, and a supporting column 7 of each set of positioning unit 6 is in inserting fit with the positioning holes 5. In addition, at least one pair of positioning support forks 10 can be further included, and the positioning support forks 10 are in inserted fit with the positioning holes 5.
As shown in fig. 3, when the workpiece is a cylinder cover, two sets of same positioning units are adopted for positioning and mounting the cylinder cover; when the workpiece is a cylinder, a set of positioning units and a pair of positioning support forks can be used for positioning and mounting the cylinder, as shown in fig. 4. Therefore, the positioning fixture and the workpiece are positioned, the workpiece and the three-coordinate detection platform are further positioned, the installation is convenient and simple, and the measurement precision is high.
