[0029] like Figure 1-4 It is a structural schematic diagram of a screw assembly machine in a preferred embodiment of the utility model. In this embodiment, a screw assembly machine includes a workbench 1, and a transmission device 2 is provided in the middle of the workbench 1. The transmission device 2 realizes the function of smooth movement of the screw. A screw feed channel 3 is fixedly installed on the top of the workbench 1 on one side of the transmission device 2, and a screw propulsion device 4 is provided on the top of the workbench 1 on one side of the output end of the screw feed channel 3, and the input end of the screw propulsion device 4 is connected with the output end of the screw feed channel 3. The screw delivered from the screw feed channel 3 is pushed to the transmission device 2 by the screw propulsion device 4. Since the rod is placed downward when the screw is delivered from the screw feed channel 3, in order to enable the rod and the nut to be assembled and reduce the installation of the device, the screw propulsion device 4 is located below the transmission device 2. When the transmission chain 23 in the transmission device 2 rotates the screw tooling 24 to the bottom of the frame 21, the screw propulsion device 4 pushes the screw into the screw tooling 2 4, through the circular rotation of the transmission chain 23, the rod of the screw is placed upward, so as to facilitate the assembly with the nut. A driving device 5 is provided on the top of the workbench 1 away from the screw propulsion device 4, and the output end of the driving device 5 is connected to the transmission device 2, which is arranged to provide a power source for the operation of the transmission device 2. A nut clamping and rotating device 6 is provided on one side of the transmission device 2 through a support frame 61, and a nut feeding channel 7 is provided on one side of the transmission device 2 through a support plate 71. The nut in the nut feeding channel 7 is clamped and rotated by the nut clamping and rotating device 6 to be assembled with the screw, and the nut feeding channel 7 is located directly behind the nut clamping and rotating device 6.

Through the opening of the connecting groove 43, the screws in the screw feed channel 3 slide into the connecting groove 43 one by one, and the connecting groove 43 is connected to the pushing groove 42. Each time the screw pushing cylinder 44 extends outward, the screw in the connecting groove 43 is pushed toward the pushing groove 42 and the screw is directly pushed into the screw tooling 24.

[0033] In this embodiment, the nut clamping and rotating device 6 includes a clamping and rotating mechanism 66, a driving cylinder 64, a fixed seat 62 and a first sliding mechanism 65. The first sliding mechanism 65 is fixedly connected at both ends of the fixed seat 62, and a connecting cavity 63 is opened in the middle of the fixed seat 62. The driving cylinder 64 is fixedly installed at one end of the fixed seat 62, and the output end of the driving cylinder 64 moves in the connecting cavity 63 and passes through the first sliding mechanism 65 to be connected to the clamping and rotating mechanism 66, thereby driving the clamping and rotating mechanism 66 to have the function of lateral movement. The clamping and rotating mechanism 660 is slidably connected to the first sliding mechanism 65.

[0035] In this embodiment, the driving device 5 includes a mounting base 51 and a driving motor 52. The mounting base 51 is fixedly mounted on the top surface of the workbench 1. The driving motor 52 is fixedly mounted on the mounting base 51, and the output end of the driving motor 52 is connected to one of the rotating rods 25, so as to drive the rotating rod 25 to rotate.

[0036] In this embodiment, a nut pushing cylinder 9 is fixedly installed on the outer wall of the nut feed channel 7 at a position relative to the clamping rotating head 664. This structural setting pushes the nut out from the nut on the nut feed channel 7, thereby facilitating the clamping rotating head 664 to clamp the nut.
