Detailed Description

With reference to fig. 1 to 3, a linear motor connecting plate combined module comprises a linear motor 10 and a connecting plate 20, wherein the connecting plate is installed on a rotor 11 of the linear motor, a groove 21 is formed in the surface of the connecting plate, which is in contact with the rotor, a cooling pipeline 30 is matched in the groove, and the cooling pipeline is provided with a water inlet 31 and a water outlet 32.

The water inlet 31 and the water outlet 32 are connected to a cooling water supply device, and the cooling water supply device and the cooling pipe 30 form a water circulation to cool the connection plate 20 and the mover 11 by being driven by a cooling water supply device water pump.

As shown in fig. 3, the groove 21 has an S-shape, and the cooling duct 30 has an S-shape. The S-shaped design can enlarge the cooling area of the cooling duct 30 for the connecting plate 20 and the mover 11, thereby improving the cooling efficiency.

The left side of the connecting plate 20 is connected with the workbench, the middle of the connecting plate is fixedly connected with the rotor 11 through a first threaded connector, as shown in fig. 1, a first opening 22 is formed in the left side of the connecting plate, so that two first convex portions 23 are formed in the left side of the connecting plate, and the workbench is fixedly connected with the two first convex portions through a second threaded connector. As an improvement, the cooling pipe 30 is in contact with the side wall of the groove 21 to improve the heat exchange efficiency of the cooling water with the connection plate 20 and the mover 11. In this way, the middle of the web, i.e. the part fixedly connected to the mover, cannot be deformed, otherwise the side walls of the groove 21 will press the cooling duct 30, causing it to break. Therefore, the utility model discloses the atress position to connecting plate 20 has improved, specifically, establishes first opening 22 in the left side of the connecting plate of being connected with the workstation, two first convex parts 23 of formation with the workstation is connected, so, two first convex parts 23 atress warp, and this deformation can be absorbed to first opening, and unlikely influence the middle part of connecting plate, does not influence recess 21 and cooling duct 30's relative position promptly.

As shown in fig. 2, the right side of the connecting plate 20 is provided with a plurality of sliding blocks 40, the sliding blocks are in sliding fit with the first guide rails 41, the right side of the connecting plate is provided with a plurality of second gaps 24, the number of the second gaps is one less than that of the sliding blocks, and the plurality of second gaps and the plurality of sliding blocks are arranged in a staggered manner. All the second gaps and all the sliding blocks are arranged in a row, and all the second gaps and all the sliding blocks are arranged in a sliding block-second gap-sliding block-second gap mode. The cooperation of first guide rail and all sliders can prevent connecting plate warpage, can improve the rectilinear movement precision of connecting plate, can support the connecting plate, improves its stability. The second gap 24 acts in the same way as the first gap 22 and is used for absorbing the deformation of the connecting plate 20 caused by the action of the slider on the connecting plate 20 and preventing the deformation from influencing the relative position of the groove 21 and the cooling duct 30.
