The present invention will be described in further detail with reference to the accompanying drawings:

referring to fig. 1 and 2, fig. 1 and 2 are an axonometric view and a left side view of a clamp of a wheel reduction assembly of the present invention, respectively, and include a clamp body, a first clamp member 1, a second clamp member 2, an electric driving device 4 of an AGV assembly cart, a clamp connector 5, a guide rail 6, a lead screw 7, a positioning pin 8, a rib plate 9 and a square head 10, wherein the first clamp member 1 and the second clamp member 2 are respectively disposed at two ends of the clamp body, the first clamp member 1 and the second clamp member 2 are respectively mounted on a slide block of the guide rail 6, the guide rail 6 is mounted on the clamp body, the lead screw 7 is mounted on the clamp body, the square head 10 for rotating the lead screw 7 is disposed on an end surface of the clamp body, and when the square head 10 is rotated, the lead screw 7 can rotate therewith, thereby driving the first clamp part 1 and the second clamp part 2 to move towards or away from each other on the guide rail 6.

The upper ends of the first clamp part 1 and the second clamp part 2 are respectively provided with a positioning pin matched with a pin hole of the workpiece 3, and the lower ends of the first clamp part 1 and the second clamp part 2 are respectively provided with a rib plate 9 for positioning a box body of the workpiece 3; and one end of the clamp body is also provided with a clamp connecting body 5 which is used for being connected with an AGV assembly trolley electric driving device 4. Referring to fig. 3, fig. 3 is a positioning azimuth diagram of the clamp of the wheel reduction assembly of the present invention; the positioning pins 8 on the first and second clamp members 1, 2 constrain five degrees of freedom of the workpiece 3

The rib plates 9 at the lower ends of the first clamp part 1 and the second clamp part 2 restrain the workpiece 3 for one degree of freedom

The workpiece is thus fully positioned.

A working method of a clamp of a wheel reduction assembly comprises the following steps:

1) the workpiece 3 is hung above the clamp body and falls down to enable the box body part of the workpiece 3 to enter the rib plates 9 at the lower ends of the first clamp part 1 and the second clamp part 2, so that initial positioning is completed;
