Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Embodiment 1

The housing frame 1 surface is provided with heat dissipation holes for achieving the heat dissipation effect of the electromagnetic drive unit 10, and different electromagnetic magnetic forces can pull different rapier bodies 9 left and right.

[0022] The lubrication assembly 16 is arranged on the top of the housing 1; the lubrication assembly 16 comprises an oil tank 2 assembled on the housing 1, a flow groove 12 opened on one side of the housing 1 around the through hole 13, and a transparent part 11 arranged at one end of the oil tank 2, an inlet is arranged on the oil tank 2, and the transparent part 11 is made of transparent glass or plastic. The amount of lubricating oil in the oil tank 2 can be known by the transparent part 11, so that it can be judged whether lubricating oil needs to be added to the oil tank 2; the top of the flow groove 12 and the bottom of the oil tank 2 are connected by a pipeline; a rotating ball 14 is rotatably installed at the position of the flow groove 12 near the through hole 13, and the middle position of the rotating ball 14 is a spherical setting, and the rotating ball 14 is in contact with the outer wall of the rapier body 9. A flow hole 15 is opened at the middle position of the rotating ball 14, and the connection between the flow hole 15 and the rotating ball 14 and the flow groove 12 is vertically arranged. A groove 8 is opened at the bottom end of one side of the housing 1, just below the through hole 13; the groove 8 is used to store the flowing lubricating oil. The oil tank 2 stores lubricating oil, which flows along the flow groove 12 to the upper surface of the rapier body 9 through the through hole 13, thereby achieving a lubricating effect. The lubricating oil in the oil tank 2 flows along the flow groove 12 and then flows to the surface of the rapier body 9. By adding lubricating oil to the surface of the rapier body 9, the friction resistance between the rapier body 9 and the frame 1 can be reduced.

[0023] During the movement of the rapier body 9, the rotating ball 14 is triggered to rotate. The rotation of the rotating ball 14 can reduce the friction resistance between the rapier body 9 and the shell frame 1, thereby improving the smoothness of the movement of the rapier body 9; when the rotating ball 14 rotates to the grading flow grooves 12 at both ends of the flow hole 15, it can block or reduce the flow of lubricating oil; when the excessive lubricating oil flows to the outer wall of the shell frame 1 or flows outside the rapier body 9, the excess lubricating oil drips into the groove 8 during the movement of the rapier body 9, and the groove 8 receives the excess lubricating oil.

[0027] Working principle: Start the electromagnetic drive unit 10, and drive the rapier body 9 to move according to the different adsorption strengths of the electromagnetic drive unit 10, thereby driving the connecting rod 4 to move left and right. During the movement of the rapier body 9, the rotating ball 14 is triggered to rotate. However, when the rotating ball 14 rotates, the liquid in the oil tank 2 flows into the flow groove 12, and then flows to the surface of the rapier body 9 through the flow hole 15. The lubricating oil flows on the surface of the rapier body 9 to play a lubricating role, reduce the friction between the rapier body 9 and the frame 1, and the electromagnetic drive can improve the rapier positioning effect with high precision.
