A limit device for movable swing arm on production line

Abstract

The invention discloses a limiting device for a movable swing arm on a production line. The limiting device comprises an upper cover, wherein a plurality of uniformly distributed screw holes are formed in the upper cover; a bolt is mounted in each screw hole; a rotary rod adapter tube is arranged on the upper cover; a limit ring is connected to the lower part of the upper cover; two fixing pieces are mounted in the limit ring; a plurality of baffle rings are mounted on each fixing piece; a lower cover is mounted under the upper cover; and a plurality of screw rods are mounted below the lower cover. As the bolts and the screw rods, of which the sizes are equal to the diameters of all hole sites in the limiting device, the phenomenon of mounting mistakes caused by mismatch between the bolts and the hole sites, as well as between the screw rods and the hole sites, during assembly cannot be caused. As the plurality of uniformly distributed baffle rings are mounted on the limit ring, and the baffle rings can be mounted and dismounted at any time, the spaces between the baffle rings can be adjusted to meet the demand for adjusting the motion range of the movable swing arm.

Description

technical field [0001] The invention relates to a limiting device, in particular to a limiting device used for a movable swing arm on a production line, and belongs to the application field of the limiting device. Background technique [0002] The existing limit devices used for movable swing arms on production lines have certain defects in use, including that the swing amplitude of the movable swing arms by the same limit device is limited to a fixed value, and it does not have the ability to limit the swinging amplitude of the movable swing arms to a fixed value. The ability to flexibly adjust the swing range due to the actual demand, so that it cannot meet the needs of flexible use of the movable swing arm on the production line. It is also necessary to replace the limit devices of different specifications, and the existing limit devices are troublesome, time-consuming and laborious to disassemble and replace. SUMMARY OF THE INVENTION [0003] The purpose of the present...
