Abstract
The invention discloses a limiting mechanism for a linear conveying device. The limiting mechanism comprises a support and a connecting rod rotatably connected to the support; two parallel linear rails are arranged above the support; a motion body slides front and back on the linear rails; the bottom surface of the motion body is provided with a limiting flange; the connecting rod is of an eccentric structure; the connecting rod is upright and blocks the limiting flange at a free state under the action of gravity; a bottom plate is arranged at the bottom of the support; the bottom plate is slidably provided with a sliding block which is positioned in front of the connecting rod; the sliding block is located below the rotating center of the connecting rod; the head of the connecting rod descends when the sliding block is pushed rearwards; the upper plane of the bottom plate is provided with a fixing block; the sliding block is arranged on the fixing block through a sliding rail structure; the sliding block slides front and back on the fixing block under the pushing of an air cylinder. According to the limiting device disclosed by the invention, the eccentric connecting rod is used for realizing limiting, and the connecting rod is upright at the free state to play a limiting role; the limiting mechanism disclosed by the invention is simple in structure and accurate in limiting.

Detailed description of the invention
A kind of connecting rod stop gear of the present invention is illustrated below in conjunction with Fig. 1 to Fig. 5, comprise support 1 and be rotatably connected on the connecting rod 2 on support, two parallel rectilinear orbits 7 are provided with above described support, one movable body 6 slide anteroposterior on described rectilinear orbit, movable body bottom surface is provided with spacing rib 61, described connecting rod is eccentric structure, during free state, connecting rod is upright under gravity and stop spacing rib, described frame bottom is provided with base plate 11, described base plate slides in connecting rod front and arranges a slide block 4, described slide block is positioned at link rotatable central lower, described slide block pusher, then link rod head falls.On described base plate, plane is provided with fixed block 3, and described slide block is located on described fixed block by rail structure, and described slide block promotes slide anteroposterior on fixed block by a cylinder 5.Described rail structure comprises the chute 31 be located on described fixed block, and described slider bottom is provided with outstanding slippery fellow 41, and described slippery fellow is located in described chute.Due to the setting of rail structure, skid process is smooth and easy not to be offset.
Described connecting rod 2 is the wide capitate structure of top narrow lower portion.Described support is provided with the angle that locating dowel pin 12 limiting rod head rotates.Described support cross-sectional plane is U-shaped, and described locating dowel pin two ends are located on support two side.Support dual-side upper edge is provided with picks up the ears 13, and rectilinear orbit is layed on track pedestal, support pick up the ears by screw or welding and track pedestal fix.
Illustrate principle of work of the present invention below:
As shown in Figure 1, upright during connecting rod 2 free state, now connecting rod is also in running order, because now small end is higher than spacing rib bottom surface, connecting rod stops spacing rib, and connecting rod bottom is stopped by fixed block 3, then movable body cannot continue move backward thus play position-limiting action.
As shown in Figure 2, after moving mass forwards moves, now connecting rod is in off working state, and cylinder 5 promotes connecting rod 2 head, because locating dowel pin 12 stops, just no longer rotates after link rotatable to certain angle.
