And threaded with the threaded hole; one end of the connecting pipe is fixed on the right side of the piston, the other end of the connecting pipe is fixed on the left side of the slider, the left coaxial line of the screw extends into the connecting pipe, and the forward and reverse The motor is fixed on the right end face of the guide cylinder, the main shaft of the forward and reverse motor stretches into the guide cylinder, and the main shaft of the forward and reverse motor is connected with the right end of the leading screw through a shaft coupling.

A sealing ring is arranged on the outer edge of the piston.

Adopting the above-mentioned technical scheme, the utility model is mainly used for electric control operation to absorb some objects with flat surfaces. Specifically, when grabbing objects, the forward and reverse motors are started, and the forward and reverse motors drive the lead screw to rotate through the shaft coupling. The thread of the rod is set in the threaded hole of the slider, and the slider is slidably connected to the slider, so the rotation of the screw will drive the slider to move to the right, so that the slider drives the piston to move to the right through the connecting tube, at this time, the inside of the suction cup Negative pressure is formed, and the external atmospheric pressure can firmly absorb the suction cup on the surface of the object to complete the suction action of the object; when the object needs to be released, just let the forward and reverse motor rotate in the opposite direction, and the lead screw drives the slider to move to the left, so that the suction cup The inner air pressure recovers, and finally the suction cup falls off from the object; in addition, there is a sealing ring on the outer edge of the piston, which is used to seal the connection between the piston and the inner wall of the installation cylinder, and the installation cylinder and the guide cylinder are connected by threads, which is convenient for disassembly and installation , when the parts in the guide cylinder or the installation cylinder are damaged, the connection between the installation cylinder and the guide cylinder can be quickly opened to replace the damaged parts.

To sum up, the utility model completes the grasping of objects through common components such as sliders, motors and suction cups, and has low manufacturing cost, which is suitable for production in modern factories.

detailed description

As shown in Figure 1 and Figure 2, the electronically controlled vacuum suction cup mechanical gripper of the present utility model includes a guide cylinder 1 and an installation cylinder 2 arranged on the same axis, with the axial direction of the guide cylinder 1 being the left and right horizontal direction, and the installation cylinder The right end of 2 is threadedly connected with the left end of the guide cylinder 1, and the left end of the installation cylinder 2 is installed with a suction cup 3. The suction cup 3 is a trumpet-shaped structure with a large left and a small right. The installation cylinder 2 is slidably connected with a piston 4 and the installation cylinder 2 The inner wall of the piston 4 is tightly matched with the outer edge of the piston 4, the outer edge of the piston 4 is provided with a sealing ring 5, and the guide cylinder 1 is provided with a piston driving mechanism;

The piston driving mechanism includes a connecting pipe 6, a slider 7, a lead screw 8 and a forward and reverse motor 9. The inner wall of the guide cylinder 1 is fixed with two slide rods 10 along the axial direction. Line symmetrical arrangement, the outer surface of the slider 7 is provided with two chute, two slide rods 10 are respectively installed in the two chute, the slider 7 is slidably matched with the slider 10 through the chute, the center of the slider 7 A threaded hole 11 is provided, and the lead screw 8 is threaded through the threaded hole 11 and connected with the threaded hole 11; one end of the connecting pipe 6 is fixed on the right side of the piston 4, and the other end of the connecting pipe 6 is fixed on the side of the slider 7.
