[0029] The use state of the present invention is as follows: the present invention has a reasonable and simple structure, low production cost, and convenient installation. When in use, the motor component to be assembled is first placed on the placement seat 1, and the clamping, fixing and position adjustment of the motor component are achieved by operating the replaceable drive mechanism 1 3 and the replaceable drive mechanism 2 6. When fixing, first insert the tool into the hexagonal groove 32 of the rotating head 1 31 and push the fixing plate 33 and the connecting square rod 1 35 to move right, and the right movement of the connecting square rod 1 35 causes the spline head 1 39 to move right and insert into the spline hole 310, and at the same time, the right movement of the spline head 1 39 will pass The cone 318 makes the movable bevel gear 315 move downward and separate from the bevel gear 1 38 and the bevel gear 2 311, and then drives the rotating head 1 31 to rotate through the tool, and the rotation of the rotating head 1 31 drives a screw 1 23 and a spline head 1 39 to rotate through the connecting square rod 1 35, and the rotation of the spline head 1 39 drives a screw 27 to rotate through the transmission shaft 2 312 and the connecting square rod 2 313. Here, when the screw 1 23 rotates, the transverse clamping block 1 22 moves inward along the transverse guide groove 1 21, and at the same time, the screw 27 rotates to make the transverse clamping block 28 rotate along the transverse guide groove When the first screw 29 is moved inward, the motor component can be clamped and fixed in the horizontal direction. Similarly, the front and rear longitudinal positions of the motor component can be clamped by the clamping adjustment mechanism 25. The transmission gear 1 24 and the connecting gear 1 25 and the transmission gear 2 26 and the connecting gear 2 210 provided in the clamping adjustment mechanism 1 2 and the clamping adjustment mechanism 25 can ensure that the three screws 1 23 and the three screws 27 rotate together, thereby ensuring the reliability and stability of the motor component after being clamped and fixed left and right, front and back. When adjusting, just insert the tool into the hexagonal groove 32 of the rotating head 31 without pushing it. The movable fixed plate 33 and the connecting square rod 1 35, at this time, the movable bevel gear 315 is in meshing state with the bevel gear 1 38 and the bevel gear 2 311. In addition, since the thread rotation directions of the screw rod 1 23 and the screw rod 2 27 are opposite, it is ensured that the transverse clamping block 1 22 and the transverse clamping block 2 28 can drive the clamped motor component to move to the left or right together, which also meets the need for lateral movement adjustment of the motor component after clamping. Similarly, the clamping adjustment mechanism 2 5 and the interchangeable driving mechanism 2 6 can also perform longitudinal movement adjustment on the clamped motor component, thereby bringing great convenience to the assembly test.
