Detailed Description

Examples

For the convenience of understanding the present invention, fig. 4 and 5 omit the component bending positioning plate, such as the positioning mechanism for the biochemical analyzer liquid tube bending tool shown in fig. 1-8, two circular arc positioning grooves 2 are formed on the surface of the workpiece positioning plate 1, and are respectively used for positioning two workpieces shown in fig. 9 and 10, and this embodiment only illustrates one workpiece positioning. Along the even installation positioning pressure plate 3 in 2 borders of circular arc constant head tank, the notch 21 processing of circular arc constant head tank 2 goes out the station of adding that bends, installs stopper 4 at the 21 borders of notch of circular arc constant head tank 2 to process out rotatory locating hole 5 on the face of notch 21 department, rotatory locating hole 5 installation internal rotation setting element 6.

The rotary positioning member 6 comprises a rotary shaft 61, a push rod 62 and a rotary shifting plate 63, the rotary shaft 61 is installed in the rotary positioning hole 5, the push rod 62 transversely penetrates through the rotary shaft 61, the rotary shifting plate 63 is installed at the front end of the push rod 62, a workpiece limiting groove 64 is formed in the bottom of the rotary shifting plate 63, and a positioning block abdicating groove 65 is formed in the bottom of the rotary shifting plate 63 corresponding to the part of the limiting block 4 in order to avoid the limiting block 4 during rotation.

In order to press the workpiece 8 at the large arc part of the arc positioning groove 2 tightly, the positioning pressing plate 3 is installed at the edge of the arc positioning groove 2 through the bolt 31, the spring 32 is installed between the positioning pressing plate 3 and the bolt 31, and the positioning pressing plate 3 provides tension pressure all the time.
