FIG. 1 is a schematic view of the present invention;
fig. 2 is a top view of the positioning mechanism.
In the figure: the device comprises a workpiece 2, a support plate 3, a shaft 4, a via hole 5, a lower pressure head 6, a pressure sensor 7, a support ring 8, a sliding groove 9, a positioning rod 10, a guide surface 11, a drive ring 12, a guide block 13, a spring 14, a bump 15 and a second bump 16.
Detailed Description
The invention will be further explained in detail with reference to the drawings and the following detailed description:
example (b):
referring to fig. 1 to 2, an automobile water pump part connecting pull-out force testing machine comprises a support plate 3 for supporting a workpiece 2, a through hole 5 located on the support plate 3 and allowing a shaft 4 in interference fit with the workpiece 2 to pass through, a lower pressing head 6 located above the support plate 3 and used for pressing the shaft 4 downwards, a pressure sensor 7 located on the lower pressing head 6, and a positioning mechanism for positioning the workpiece 2;
the outer edge of the workpiece 2 is circular, and the workpiece 2 and the via hole 5 are coaxial;
the positioning mechanism comprises a support ring 8 fixed on the support plate 3, a plurality of sliding grooves 9 positioned on the support ring 8, positioning rods 10 connected in the sliding grooves 9 in a sliding manner, guide surfaces 11 positioned at one ends, far away from the via holes 5, of the positioning rods 10, a driving ring 12 connected on the support plate 3 in a rotating manner, guide blocks 13 fixed on the inner side of the driving ring 12 and used for being matched with the guide surfaces 11 to drive the positioning rods 10 to move axially, and springs 14 used for rotating the driving ring 12 so that the positioning rods 10 clamp the workpiece 2.
The positioning rod 10 is made of iron, and the guide block 13 is made of a magnet.
The positioning rods 10 are located on an axial cross section of the support ring 8, the positioning rods 10 being arranged in an annular array centered on the axis of the support ring 8.
