Abstract

The invention discloses a split pin type hold-down device comprising a support. A cylinder is fixed on the support, the outer end of a piston rod matched with the cylinder is connected with a connector which is located on the inner side of a cylinder seat, the cylinder seat is supported by the support, push-pull arms are uniformly distributed on the upper peripheral edge of the connector and connected with the connector through pin shafts, one end of a pressing arm is connected with the corresponding push-pull arm through a first rotating shaft, the other ends of the pressing arms are connected through second rotating shafts in a manner of rotating relative to the cylinder seat, each pressing arm is fixedly connected with a pressing block, and fixing blocks matched with the pressing blocks are arranged on the outer side of the cylinder seat. The split pin type hold-down device has the advantages of simple structure, flexibility and reliability in action, small occupied space and full utilization of internal space of flanging holes in workpieces.

Description

Split pin formula hold down gag
Technical field
The present invention relates to a kind of positioner of applying on body in white welding and assembling production lines of being suitable for, be particularly useful for space on production line less and have a situation of flanging bore.
Background technology
At present, on automobile body-in-white welding production line, apply many positioners, due to limited space on production line, positioner needs again to take certain position, for its inner space, hole of workpiece that has flanging bore, frock being set is very necessary for being fixed, and can solve the problem that space unskilled labourer on production line fills layout difficulty.
Summary of the invention
Order of the present invention is to provide that a kind of simple in structure, flexible movements are reliable, the Split pin formula hold down gag little, that make full use of inner space, workpiece upper overturning hole that takes up room, and overcomes the deficiencies in the prior art.
Split pin formula hold down gag of the present invention, comprise bearing, on bearing, be fixed with cylinder, the external end head of the piston rod matching with cylinder is connected to connector, connector is positioned at the inner side of cylinder base, cylinder base is by seat supports, connector upper periphery is evenly distributed with push-pull arm, push-pull arm is that bearing pin is connected with connector, between one end of pressure arm and push-pull arm, by the first rotating shaft, be connected, the other end of pressure arm is rotationally connected with respect to cylinder base by the second rotating shaft, and pressure arm is fixedly connected with briquetting, is provided with the fixed block matching with briquetting in the outside of cylinder base.
Described fixed block is located at bearing upper end with in the gripper shoe being fixedly connected with bearing.
Described gripper shoe is fixedly connected with installing plate, and installing plate is fixedly connected with bearing by hornblock.
Split pin formula hold down gag of the present invention, is fixed in the frame of production line by bearing during installation, makes the parts on bearing just be positioned at inside, workpiece upper overturning hole during work.Cylinder action under air control unit drives, when piston rod is retracted, connector drives each push-pull arm servo-actuated, pressure arm rotates, and briquetting is upwards rotated, and the fixed block of briquetting and its below leaves, in open mode, workpiece pressing not now, when piston rod oppositely moves, above-mentioned each part counteragent, briquetting presses to fixed block, and workpiece flanging bore periphery is fixed.Simple in structure, flexible movements are reliable, take up room little, take full advantage of the space of workpiece flanging bore inside.
Accompanying drawing explanation
Fig. 1 is the structural representation of the specific embodiment of the invention.
The specific embodiment
As shown in Figure 1: 1 is bearing, has been bolted hornblock 2 on bearing 1, and a side of hornblock 2 has been bolted installing plate 4, and cylinder 3 is fixedly mounted on installing plate 4, is connected to gripper shoe 13 on installing plate 4, is fixed with cylinder base 5 in gripper shoe 13.The piston rod end matching with cylinder 3 is connected to connector 6, at the periphery of connector 6, by bearing pin, is connected with push-pull arm 7, and push-pull arm 7 is three groups and is uniformly distributed at connector 6 peripheries.8 is pressure arm, and one end of pressure arm 8 is connected with push-pull arm 7 by the first rotating shaft 9, and the other end of pressure arm 8 is connected on support by the second rotating shaft 10, and support is fixedly connected with cylinder base 5 tops.On pressure arm 8, be fixedly connected with briquetting 11.In the outside of cylinder base 5, be provided with the fixed block 12 matching with briquetting 11.Fixed block 12 is fixed in bearing 1 upper end and gripper shoe 13 by each contiguous block, and the shape of opening of contiguous block can be according to the shape of workpiece and location positioning, as long as guarantee, logically coordinate clamping workpiece with briquetting 11.
During installation, by bearing 1, be fixed in the frame of production line, during work, make the parts on bearing 1 just be positioned at inside, workpiece upper overturning hole.Cylinder 3 action under air control unit drives, when piston rod is retracted, connector 6 drives each push-pull arm 7 servo-actuated, pressure arm 8 rotates, and briquetting 11 is upwards rotated, and briquetting 11 leaves with the fixed block 12 of its below, in open mode, workpiece pressing not now, when piston rod oppositely moves, above-mentioned each part counteragent, briquetting 11 presses to fixed block 12, and workpiece flanging bore periphery is fixed.Simple in structure, flexible movements are reliable, take up room little, take full advantage of the space of workpiece flanging bore inside.
