[0004] However, in the prior art, when performing wire tying operations on a stator, most of the current traditional wire tying machines can only tie wires for a stator of a single size. When tying wires for other stators of different sizes, different fixing devices need to be replaced, thereby increasing the production cost of the enterprise and causing a certain degree of limitation to the practicality of the device. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the problem in the prior art that most of the current traditional wire tying machines can only tie wires for a stator of a single size, and different fixing devices need to be replaced when tying wires for other stators of different sizes, thereby increasing the production cost of the enterprise.

[0006] To achieve the above object, the utility model adopts the following technical solutions: A wire tying machine for stator production, comprising a placement plate, a rotating assembly and a positioning assembly. The positioning assembly includes a placement disk, and the upper surface of the placement disk is successively provided with a first installation groove and a second installation groove from top to bottom. The inner side wall of the first installation groove is movably connected with a second bidirectional lead screw, and a worm gear is fixedly connected to the middle of the second bidirectional lead screw. A driving motor is arranged in the inner cavity of the placement disk. The inner side wall of the second installation groove is movably connected with a first bidirectional lead screw, and the output shaft of the driving motor is in transmission connection with the first bidirectional lead screw. A worm is fixedly connected to the middle of the first bidirectional lead screw, and the worm is meshed with the worm gear. Displacement blocks are symmetrically screwed on the surfaces of the first bidirectional lead screw and the second bidirectional lead screw. A positioning block is fixedly connected to the upper surface of the displacement block, and anti-slip bumps are arranged inside the positioning block.

[0007] As a preferred embodiment, the rotating assembly includes a support frame, and a rotating motor is fixedly connected to the upper surface of the support frame. A second rotating shaft is fixedly connected to the center of the lower surface of the placement disk.

[0008] As a preferred embodiment, the output shaft of the rotating motor is in transmission connection with a first rotating shaft, and the first rotating shaft is in transmission connection with the second rotating shaft through a transmission belt.

[0009] As a preferred embodiment, an installation frame is fixedly connected to the upper surface of the placement plate, and a second motor is fixedly connected to the center of the upper surface of the installation frame.

[0010] As a preferred embodiment, the output shaft of the second motor is in transmission connection with a second electric telescopic rod, and the output end of the second electric telescopic rod is in transmission connection with an upper hook needle.

[0011] As a preferred embodiment, a hydraulic cylinder is fixedly connected to one side of the upper surface of the installation frame. A chute is arranged on the inner side wall of the installation frame. The output shaft of the hydraulic cylinder is in transmission connection with a hydraulic rod, and one end of the hydraulic rod is fixedly connected to a slider.

[0012] As a preferred embodiment, a first motor is fixedly connected to one side of the slider. The output shaft of the first motor is in transmission connection with a first electric telescopic rod, and the output shaft of the first electric telescopic rod is in transmission connection with a lower hook needle.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are as follows:

The first bidirectional lead screw drives the worm gear to rotate through the worm, and the worm gear drives the displacement block to rotate. Thus, the displacement block drives the positioning block to move from the outside to the inside to clamp and fix stators of different sizes. Due to the design of the anti-slip convex blocks, the sliding of the fixed stator is avoided, and the safety and stability of the device are improved. BRIEF DESCRIPTION OF THE DRAWINGS
