Abstract

A friction stir welding pneumatic compression tool, which relates to the improvement of a non-ferrous metal profile processing part, is characterized in that: double basic rails are fixed on the friction stir welding basic tool, and two sets of upper and lower rails roll and cooperate with the double basic rails through rollers, There are pressing beams between the two sets of upper and lower rails, and several sets of pressing devices are installed on the pressing beams. Rotation support points are provided at the bottom of the pressing beams and the middle of the pressing arms of the pressing devices. The rear part of the clamping arm cooperates with the transmission of the cylinder. The front end of the clamping arm of the clamping device is fixed with a clamping pad. The clamping devices under the two sets of clamping beams are in a symmetrical state. The ends of the two sets of clamping beams are connected with the upper and lower track devices. The linear guide rails are slidingly matched, and the motors and reducers on the ends of the two sets of pressing beams are matched with the gear racks in the upper and lower track devices. The beneficial effect is: the application of the tooling does not affect the various functions of the friction stir welding machine, and the processed products less than 6 meters can be pressed, and the pressing is fully automated, reducing the assembly time of the workpiece.

Description

Friction stir welding pneumatic compression tooling

technical field

The utility model belongs to the technical field of mechanical equipment and relates to an improvement of a non-ferrous metal profile processing part.

Background technique

At present, for the processing of non-ferrous metal profiles, manual and hydraulic compression are used for friction stir welding compression, the compression speed is slow, and the work efficiency is low. Sometimes the local compression force is too small due to the operator's reasons, and there is leakage at the compression point. drop, quality problems often occur.

Contents of the invention

The purpose of the utility model is to provide a friction stir welding pneumatic compaction tool, which can automatically realize the friction stir welding pneumatic compaction.

The technical scheme of the utility model is: it is made up of basic track device, upper and lower track device, pressing beam device, pneumatic device and electric device.

The double basic rails are fixed on the friction stir welding basic tooling, and the two sets of upper and lower rails are rolled and matched with the double basic rails through rollers. There are pressing beams between the two sets of upper and lower rails, and several sets of pressing devices are installed on the pressing beams. There is a rotating support point at the bottom of the compression beam and the middle part of the compression arm of the compression device. The rear part of the compression arm of the compression device cooperates with the transmission of the cylinder, and the front end of the compression arm of the compression device is fixed with a compression pad. The compression device under the compression beam is in a symmetrical state. The ends of the two sets of compression beams are slidingly matched with the linear guide rails of the upper and lower track devices. The gear rack drive fits in the device.

The beneficial effect of the utility model is: the application of the tooling does not affect the various functions of the friction stir welding machine, it can compress the processed products less than 6 meters, the compression is all automatic, and the assembly time of the workpiece is reduced.

detailed description

Below in conjunction with accompanying drawing, the utility model is further described:

As shown in Figure 1, 1 is the basic track device, 2 is the upper and lower track device A, 3 is the pressing beam A, 4 is the cylinder A, 5 is the pressing arm A, 6 is the pressing pad A, and 7 is the motor device A, 8 are upper and lower track devices B, 9 are compression beams B, 10 are cylinders B.

As shown in Figure 2, 11 is a roller, and 12 is a safety hook.

As shown in Figure 3, 13 is a motor, 14 is a reducer, 15 is a positioning pin, 16 is a rack, and 17 is a linear guide.

As shown in Figure 4, 18 is a support shaft.

Two basic rails 1 are equal to double basic rails. Similarly, the bottom of each upper and lower rail device is equal to four rollers 11, so that the upper and lower rail devices move more smoothly. Safety hooks are installed at the bottom of the upper and lower rail device sides to realize alignment. The fixing of the upper and lower track devices, the pressing beam moves up and down through the motor, reducer and rack to meet the needs of the workpiece. The pressing arm is a curved rod, and the middle part of the pressing arm is sleeved on the supporting shaft, and the supporting shaft becomes the support point, the compression arm becomes a lever. When the cylinder is activated, it drives the compression arm to move up and down, and the compression arm drives the compression pad to move up and down. The compression pad realizes the compression of the workpiece and achieves the purpose of friction stir welding.
