Abstract

The utility model relates to an automatic prebending mechanism for preassembled buckling. A vertical template is fixedly connected to the outer side of an air cylinder of one end of a piston rod of the automatic prebending mechanism, and vertical connecting plates are respectively fixedly arranged on two sides of the upper end of the template. One end of a clamping block is connected between the upper portions of the connecting plates on two sides of the upper end of the template through a rotating pin, and the other end of the clamping block is located in a U-shaped fixed seat and rotatably connected with the U-shaped fixing seat. The fixing seat is fixedly connected with a rod end of the piston rod. A fixed idler wheel is mounted between the upper ends of the connecting plates on two sides of the upper end of the template. A pressing arm is mounted on the top, corresponding to the piston rod, of the clamping block, a movable idler wheel is mounted at the other end of the upper portion of the pressing arm, and the movable idler wheel is correspondingly matched with the fixed idler wheel. The automatic prebending mechanism is suitable for prebending operations of buckling of preassembled stations of various types of car body sides and floor assemblies, and conveniently and safely meets production rhythm. Original manual prebending through skilled labor operation takes about 30 seconds of working time, through utilization of the automatic prebending mechanism to operate, the working time is 5 seconds, so productivity is promoted.

Background technology

At automobile factory's workshop vehicle body automation line that is welded, before the total assembly of gusset and floor, to carry out the pre-assembly of gusset and floor assembly through a pre-station of piecing together first, after the pre-assembly in gusset and floor, need to carry out with several places' prepackage hasps of floor lap position by gusset doorframe and gusset bottom preliminary fixing, then be transported to total assembly that next station carries out vehicle body.In the existing technique, need to be after gusset be pieced together clamp in advance, operating personnel enter manual hammer and the pliers of using of interior of body and carry out the pre-bending work of hasp, and very trouble operates; And also be the bottleneck station of automation line productive temp, need very skilled operation, ability basic guarantee productive temp; herein The most important thing is that this station needs operating personnel to enter and carries out operation in the vehicle body, itself also exists very large potential safety hazard.

The utility model content

In order to solve the existing problem of pre-assembly station of above-mentioned gusset and floor assembly, and can realize that various switches, the utility model provides a kind of automatic pre-bending mechanism of prepackage hasp that is installed on the anchor clamps.

Concrete structural design scheme is as follows:

Body side wall and floor prepackage hasp comprise cylinder 5 with automatic pre-bending mechanism, the upright template 1 that cylinder 5 outsides of piston rod one end are being fixedly connected with, both sides, described template 1 upper end are fixed with respectively upright connecting plate 2, an end that is connecting clamp 4 between two side connecting plates, 2 tops by shipping and reselling on another market, the other end of clamp 4 is positioned at the holder 7 of U-shaped, and is rotationally connected; Described holder 7 is being fixedly connected with the rod end of piston rod; Two side connecting plates are provided with fixed idler whell 8 between 2 upper ends; Clamp 4 tops corresponding with piston rod are provided with pressure arm 6, and an end of the pressure arm 6 corresponding with fixed idler whell 8 is upturned, and the end that upwarps of pressure arm 6 is provided with action roller 3, and action roller 3 and fixed idler whell 8 cooperate.

The operating pressure of described cylinder 5 is 30kg～40kg.

Described pressure arm 6 is Z-shaped arm, and its end that is positioned at the bottom is being fixedly connected with the top of clamp 4, and its superposed other end is provided with action roller 3.

The diameter of described fixed idler whell 8 is identical with the diameter of action roller 3, is 10mm～30mm; The width of fixed idler whell 8 is identical with the width of action roller 3, greater than by the width 3mm～5mm of pre-bending part.

The utility model carries out the pre-bending operation of hasp applicable to the body side wall of various vehicles and the pre-assembly station of floor assembly, and satisfies easily and safely productive temp; The manual pre-bending of former personnel, skilled worker's operation, man-hour, about 30s used the utility model operation, and be 5s man-hour, so that production capacity gets a promotion.

The specific embodiment

Below in conjunction with accompanying drawing, by embodiment the utility model is done to describe further.

Referring to Fig. 1, body side wall and floor prepackage hasp comprise cylinder 5 with automatic pre-bending mechanism, the upright template 1 that cylinder 5 outsides of piston rod one end are being fixedly connected with, both sides, template 1 upper end are installed with respectively upright connecting plate 2, an end that is connecting clamp 4 between two side connecting plates, 2 tops by shipping and reselling on another market, the other end of clamp 4 is positioned at the holder 7 of U-shaped, and is rotationally connected; Holder 7 is being fixedly connected with the rod end of piston rod.Two side connecting plates are equipped with fixed idler whell 8 between 2 upper ends; Clamp 4 tops corresponding with piston rod are equipped with pressure arm 6, and pressure arm 6 is Z-shaped arm, and its end that is positioned at the bottom is being fixedly connected with the top of clamp 4, on its superposed other end action roller 3 are installed, and action roller 3 and fixed idler whell 8 cooperations.
