When in use, the cylinder body to be assembled is first placed on the surface of the conveying plate, and the cylinder body is near the back side of the arc-shaped contact ring. Then, the hydraulic cylinder body is started, and the arc-shaped contact ring is driven to move by the hydraulic cylinder body. Then, the back side of the arc-shaped contact ring will contact the cylinder body. Then, the cylinder body is driven to move in the direction of the positioning groove by the arc-shaped contact ring. Then, the hydraulic cylinder body will drive the connecting block to move. Then, the connecting block will drive the connecting plate to move toward the back side. Then, the connecting plate will drive the rack plate body to move toward the back side. When the rack plate body moves toward the back side, the rack plate body will drive the rotating gear to rotate. Then The rear rotating gear will drive the first transmission roller to rotate, and then the first transmission roller will drive the belt body to rotate, and then the belt body will drive the second transmission roller to rotate, and then the second transmission roller will drive the bidirectional screw rod body to rotate. When the bidirectional screw rod body rotates, the first movable ring and the second movable ring will approach each other, and at this time the top plate will slide to the right side inside the sliding groove, so that the top plate will drive the resistance block to move to the right side, and then the resistance block and the anti-slip convex ball will resist the left side surface of the cylinder body. Similarly, the right side surface of the cylinder body will also be resisted, and at this time the hydraulic cylinder body pushes the front surface of the cylinder body, so that the front surface of the cylinder body will also be resisted and fixed. When the present design starts the hydraulic cylinder body to drive the arc-shaped resistance ring to push the cylinder body, it can also make the two sets of top plates approach each other, so that the present design can simultaneously position and clamp the front surface and left and right surfaces of the cylinder body, so that the clamping operation can be completed at one time, and the overall clamping effect is better.

Then, the design of the first support block and the second support block can support the parts to be assembled, and can also keep the parts to be assembled in a horizontal state with the position of the cylinder body below. The overall positioning effect is good. When the positioning is completed, the first telescopic rod and the second telescopic rod are started. At this time, the first telescopic rod and the second telescopic rod begin to return to their original positions, thereby releasing the support for the parts to be assembled, and then the parts to be assembled are positioned and assembled with the cylinder body below.
