[0014] The following is combined with Figure 1-3 This application is described in further detail.

[0015] The present application embodiment discloses a screw assembly machine, referring to Figure 1 , Figure 2 and Figure 3, including a support block 1 and a movable plate 21, one end of the top of the support block 1 is provided with a support assembly 3 for supporting the hexagonal nut, the bottom end of the movable plate 21 is slidably connected to the inside of the support block 1, so that the movable plate 21 can only approach or move away from the support assembly 3, a first motor 22 is fixedly embedded in the middle of one of the inner side walls of the support block 1, a threaded rod 23 is threaded through the bottom end of one side of the movable plate 21, one end of the threaded rod 23 is welded to the power shaft of the first motor 22, and the other end of the threaded rod 23 is rotatably inserted in the middle of the other inner side wall of the support block 1, the power shaft of the first motor 22 drives the threaded rod 23 to rotate, and the threaded rod 23 can push the movable plate 21 toward during the rotation process. As the second motor 24 approaches the support assembly 3, a second motor 24 is fixedly installed in the middle of one side of the movable plate 21. The power shaft of the second motor 24 rotates and penetrates the movable plate 21. An inner hexagonal movable cylinder 25 is welded to the end of the power shaft of the second motor 24. After the screw rod is movably inserted into the inner hexagonal movable cylinder 25, the inner hexagonal movable cylinder 25 can support the screw rod so that the screw rod is in a horizontal state. In the process that the second motor 24 moves with the movable plate 21 to approach the support assembly 3, the second motor 24 drives the inner hexagonal movable cylinder 25 to rotate, and the inner hexagonal movable cylinder 25 drives the screw rod to rotate, and then the thread penetrates the hexagonal nut in the support assembly 3, so as to achieve the purpose of assembling the hexagonal nut and the screw rod.

[0016] Reference Figure 2 and Figure 3 The support assembly 3 is composed of a support plate 31 and a hexagonal fixing cap 32. The support plate 31 is welded to one end of the top of the support block 1, and the hexagonal fixing cap 32 is welded to one side of the support plate 31. The support plate 31 can be used to support and fix the hexagonal fixing cap 32. The hexagonal fixing cap 32 corresponds to the hexagonal movable cylinder 25, so that the screw rod and the hexagonal nut in the hexagonal fixing cap 32 are in the same straight line. One of the inner side walls of the hexagonal fixing cap 32 and one side of the support plate 31 are provided with through holes, and the two through holes are in a connected state. In this way, the screw rod can continue to penetrate the two through holes after the thread penetrates the hexagonal nut in the hexagonal fixing cap 32, without conflicting with the hexagonal fixing cap 32 and the support plate 31.

[0017] Reference Figure 2 A limiting rod 4 is provided at the inner top of the support block 1, and the two ends of the limiting rod 4 are respectively welded to two inner side walls of the support block 1. The movable plate 21 is movably sleeved on the outer surface of the limiting rod 4. The limiting rod 4 can be used to support the movable plate 21, thereby alleviating the phenomenon that the threaded rod 23 is bent due to the gravity exerted by the movable plate 21 on the threaded rod 23.

[0018] Reference Figure 1 and Figure 2Support rods 51 are welded at both ends of the bottom of the support block 1, and the two support rods 51 cooperate to support the support block 1. Bolts 52 are threaded through both ends of the top of the two support rods 51. By rotating the four bolts 52 and threading them together with the surface of the external workbench, the support block 1 can be fixed on the external workbench.

[0019] The implementation principle of a screw assembly machine in an embodiment of the present application is as follows: when in use, the hexagonal nut is inserted into the hexagonal fixing cap 32, and then the screw rod is inserted into the inside of the hexagonal movable cylinder 25, and at the same time, the outer surface of the hexagonal end of the screw rod is in conflict with the inner wall of the hexagonal movable cylinder 25, and then the first motor 22 and the second motor 24 are started, and the first motor 22 drives the threaded rod 23 to rotate, and the threaded rod 23 can push the movable plate 21 toward the direction of the hexagonal fixing cap 32 during the rotation process, and the second motor 24 moves with the movable plate 21 to approach the support component 3, and the second motor 24 drives the hexagonal movable cylinder 25 to rotate, and the hexagonal movable cylinder 25 drives the screw rod to rotate, and then the thread penetrates the hexagonal nut in the support component 3, so as to achieve the purpose of assembling the hexagonal nut and the screw rod.
