Description

Flower pin type pressing device

technical field

The utility model relates to a positioning device suitable for use in a body-in-white welding and assembly production line, and is especially suitable for the situation that the space on the production line is small and there are flanging holes.

Background technique

At present, many positioning devices are used on the automobile body-in-white welding production line. Due to the limited space on the production line, the positioning devices need to occupy a certain position. For workpieces with flanging holes, it is very necessary to install tooling for pressing and fixing the inner space of the hole. , which can solve the problem of difficult layout of small space tooling on the production line.

Contents of the invention

The purpose of the utility model is to provide a flower pin type pressing device with simple structure, flexible and reliable action, small space occupation and full use of the internal space of the flange hole on the workpiece, so as to overcome the shortcomings of the prior art.

The flower pin type pressing device of the utility model comprises a support, on which a cylinder is fixed, and the outer end of the piston rod matched with the cylinder is connected with a connecting head, the connecting head is located inside the cylinder seat, and the cylinder seat is formed by the support Seat support, push-pull arms evenly distributed on the periphery of the connector, the push-pull arm and the connector are pin-connected, one end of the pressing arm is connected to the push-pull arm through the first rotating shaft, and the other end of the pressing arm is relative to the barrel through the second rotating shaft The seat is rotatably connected, the pressing arm is fixedly connected with a pressing block, and a fixing block matched with the pressing block is arranged on the outer side of the barrel seat.

The fixed block is arranged on the upper end of the support and the support plate fixedly connected with the support.

The support plate is fixedly connected with the installation plate, and the installation plate is fixedly connected with the support through the corner block.

The flower pin type pressing device of the utility model is fixed on the frame of the production line through the support during installation, and the parts on the support are just located inside the flange hole on the workpiece during operation. The cylinder moves under the drive of the pneumatic control device. When the piston rod is retracted, the connecting head drives the push-pull arms to follow, and the pressing arm rotates to make the pressing block rotate upwards. The pressing block is separated from the fixed block below and is in an open state. To tighten the workpiece, when the piston rod moves in the opposite direction, the above-mentioned components will act in the opposite direction, and the pressure block will press against the fixed block to compress and fix the periphery of the flanged hole of the workpiece. The structure is simple, the action is flexible and reliable, and the space occupied is small, making full use of the space inside the flange hole of the workpiece.

Description of drawings

Fig. 1 is a schematic structural view of a specific embodiment of the utility model.

Detailed ways

As shown in Figure 1: 1 is a support, on which a corner block 2 is fixed by bolts, one side of the corner block 2 is fixed with a mounting plate 4 by bolts, the cylinder 3 is fixedly installed on the mounting plate 4, and the mounting plate 4 is connected with a support plate 13, and the support plate 13 is fixed with a cylinder seat 5. The end of the piston rod matched with the cylinder 3 is connected with a connecting head 6, and the periphery of the connecting head 6 is connected with a push-pull arm 7 through a pin shaft. 8 is a pressing arm, one end of the pressing arm 8 is connected with the push-pull arm 7 by the first rotating shaft 9, and the other end of the pressing arm 8 is connected on the support by the second rotating shaft 10, and the support is fixedly connected with the cylinder seat 5 top. A pressing block 11 is fixedly connected to the pressing arm 8 . A fixing block 12 matched with the pressing block 11 is arranged on the outer side of the cylinder base 5 . Fixing block 12 is fixed on bearing 1 upper end and support plate 13 by each connecting block, and the opening shape of connecting block can be determined according to the shape and the position of workpiece, as long as guarantee to pass and clamp workpiece with briquetting block 11 and get final product.

During installation, it is fixed on the frame of the production line by the support 1, and the parts on the support 1 are just positioned at the inside of the flange hole on the workpiece during work. The cylinder 3 moves under the drive of the pneumatic control device. When the piston rod is retracted, the connecting head 6 drives the push-pull arms 7 to follow up, and the pressing arm 8 rotates to make the pressing block 11 rotate upwards. In the open state, the workpiece is not pressed at this time. When the piston rod moves in the opposite direction, the above-mentioned components act in the opposite direction, and the pressure block 11 presses against the fixed block 12 to compress and fix the periphery of the flanged hole of the workpiece. The structure is simple, the action is flexible and reliable, and the space occupied is small, making full use of the space inside the workpiece flanging hole.
