Bending device for stroke blocking points of guide rails

Abstract

The invention provides a bending device for stroke block points of guide rails. The bending device comprises a rack, bending assemblies and an air cylinder. Each bending assembly comprises an angular-shaped mounting frame. Each mounting frame is provided with a driving electric cylinder and an impact sliding plate capable of moving along the longitudinal direction. The output end of each driving electric cylinder is connected to the corresponding impact sliding plate. A connecting rod is longitudinally arranged on each impact sliding plate. A bending head rocker is rotatably connected to the bottom end of each connecting rod. A first rotary shaft is arranged at the bottom end of each connecting rod. Each first rotary shaft is movably arranged in a waist-shaped hole of the corresponding bending head rocker. A bending head is formed at the other end of each bending head rocker. A second rotary shaft is arranged at the position of each included angle of each bending head and the corresponding bending head rocker. A guide rail pressing block used for location of the corresponding guide rail is arranged at the bottom end of each mounting frame. A cavity used for location of the corresponding guide rail is formed in each guide rail pressing block. Each bending head is rotatably located in the corresponding cavity. According to the bending device for the stroke blocking points of theguide rails, a lever mechanism principle is adopted; original rectilinear motion is transformed into motion direction of bending of the blocking points; the technological process of size-striking of the blocking points is completed through two levers; and the structure is compact.

Description

technical field [0001] The invention relates to a sliding rail stroke stop point bending device for preparing bending points on the surface of the sliding rail. Background technique [0002] See attached figure 1 As shown, the slide rail includes a male rail and a female rail that are nested together, and a travel stop point needs to be set between the two. The function of the travel stop point is to control the stroke of the slide rail and prevent the slide rail from running out of the fixed travel range. The point is to bend the slide rail to the middle position to form two bending stop points (the arrow position is the bending direction). The difficulty lies in the small space structure of the slide rail, and it is difficult for ordinary mechanical bending mechanisms to enter the slide rail to make it forming. Contents of the invention [0003] In order to overcome the deficiencies existing in the prior art, the object of the present invention is a sliding rail stroke...
