Abstract

The invention relates to a mechanical arm, in particular to a magnetic attracting type mechanical arm with adjusting positions. The magnetic attracting type mechanical arm comprises a base with a mounting hole, a power structure and a grabbing structure. The power structure comprises a vertical air cylinder and a horizontal air cylinder, and the end portion of the vertical air cylinder is connected to the base. The grabbing structure comprises a mounting plate, an electromagnet which is connected to the lower portion of the mounting plate, a storage battery and an electronic timer. The mounting plate is connected to the end portion of a piston rod of the horizontal air cylinder, the storage battery is arranged on the base, and a coil in the electromagnet is electrically connected with the electronic timer and the storage battery in sequence. A connecting plate is provided with a guide groove and a long-strip-shaped hole, a piston rod of the vertical air cylinder penetrates through the long-strip-shaped hole and is fixedly connected with the bottom of the horizontal air cylinder, a fixing ring is arranged on an upper end cover of the vertical air cylinder, a rotating arm which can rotate around the fixing ring is arranged on the periphery of the fixing ring, and the rotating arm is provided with a guide rod which penetrates through the guide groove. According to the magnetic attracting type mechanical arm, the position of a grabbing end is adjustable, so that the requirement for mounting is low, and the mounting efficiency is improved.

Example Embodiment

[0011] like figure 1 As shown, a position-adjustable magnetic adsorption manipulator includes a base 1 with mounting holes, a power structure and a grabbing structure. The power structure includes a vertical cylinder 2 and a horizontal cylinder 9, and the end of the vertical cylinder 2 is connected to On the base 1; the grasping structure includes a mounting plate 10, an electromagnet 11 connected to the lower part of the mounting plate 10, a battery 3 and an electronic timer 4, the mounting plate 10 is connected to the end of the piston rod of the horizontal cylinder 9, and the battery 3 is arranged in On the base 1, the coil in the electromagnet 11 is electrically connected to the electronic timer 4 and the battery 3 in sequence; wherein, the connecting plate 8 is provided with a guide groove and a long hole 81, and the piston rod of the vertical cylinder 2 passes through The elongated hole 81 is fixedly connected to the bottom of the horizontal cylinder 9, the upper end cover of the vertical cylinder 2 is provided with a fixing ring 6, the periphery of the fixing ring 6 is provided with a rotating arm 5 that can rotate around it, and the rotating arm 5 is provided with a limiter to limit its own rotation. The locking screw 13 and the guide rod 7 passing through the guide groove, one side of the guide groove is provided with a pressing screw 12 to limit the displacement of the piston rod of the vertical cylinder 2 .

[0012] When using the present invention, the rotation angle of the grasping end of the manipulator on the horizontal plane can be adjusted by adjusting the rotating angle of the rotating arm 5, and the expansion and contraction of the grasping end on the horizontal plane can adjust the position of the piston rod of the vertical cylinder 2 in the elongated hole 81. Location. After the manipulator is installed, adjust the rotation angle of the rotating arm 5 in the horizontal direction and the position of the piston rod of the vertical cylinder 2 in the elongated hole 81 of the connecting plate 8 according to the position where the workpiece is grasped. error.

[0013] Specific workflow:

[0014] like figure 1 As shown in the figure, taking the workpiece to be transported on the plane where the mounting seat is located, and the delivery end point at the upper left as an example, the present invention is installed on the worktable through the mounting hole, and the rotation angle of the rotating arm 5 in the horizontal direction is adjusted according to the position of the workpiece to be grasped. , and the position of the piston rod of the vertical cylinder 2 in the elongated hole 81 of the connecting plate 8, the installation error can be eliminated, the upper air inlet of the vertical cylinder 2 is inhaled, and the piston rod of the vertical cylinder 2 drives the electromagnet 11 moves down, and the electromagnet 11 is electromagnetized. At this time, the workpiece is adsorbed, and the lower air inlet of the vertical cylinder 2 and the right air inlet of the horizontal cylinder 9 are controlled to take in air, and the electromagnet 11 that adsorbs the workpiece moves to the upper left. After reaching the designated place, the electromagnet 11 is powered off and the workpiece is released, wherein the on-off time of the coil of the electromagnet 11 is set by the electronic timer 4 .

[0015] The above are only the preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, some modifications and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection of the present invention. scope, these will not affect the effect of the implementation of the present invention and the practicability of the patent.
