An ultra-long stroke servo electric cylinder

Abstract

The present invention discloses an ultra-long stroke servo electric cylinder, comprising an electric cylinder body and a guide rail. The guide rail and the auxiliary support plate can help to increase the rigidity of the electric cylinder so that it can operate stably under a long stroke. When the auxiliary support plate moves, it moves through a roller at the left side end. The roller can balance gravity. By arranging a transmission component above the auxiliary support plate, when the auxiliary support plate moves, it can indirectly and automatically drive a piston to move in a piston groove through tooth patterns to squeeze the air in the piston groove and transmit it to the air permeable groove. The air is transmitted to the top of the auxiliary support plate through the bottom of the air permeable groove, thereby improving the air flow at the side ends of the guide rail and the auxiliary support plate, facilitating the heat dissipation of the guide rail and the auxiliary support plate, and reducing the dust content on the side ends of the guide rail and the auxiliary support plate, thereby saving electric energy and reducing energy consumption. By arranging a shearing component at the left end of the auxiliary support plate, the shearing plate can cut off the flexible or semi-flexible object at the left side end of the auxiliary support plate, thereby improving the functionality of the electric cylinder during actual operation.

[0034] Fifth, power can be applied to the handle 62 on the side of the limit frame 61, and the bidirectional screw 63 can be driven to rotate. The bidirectional screw 63 can also drive the clamping plates 64 at both ends to rotate toward each other. The clamping plates 64 at both ends can be clamped and fixed with the outer ends, which is convenient for fixing the electric cylinder, improving the stability of the electric cylinder when placed, and facilitating the clamping and fixed placement of external objects.

[0035] The present invention provides an ultra-long stroke servo electric cylinder through improvement. The guide rail 2 and the auxiliary support plate 3 can help increase the rigidity of the electric cylinder so that it can operate stably under a long stroke. When the left end of the auxiliary support plate 3 moves, it moves through the roller 4 at the left side end. The roller 4 can balance the gravity.
