Description

Technical Field

[0001] The invention relates to the technical field of friction stir welding fixtures, in particular to a friction stir welding fixture capable of processing welding waste chips. Background Art

[0002] A fixture is a device used to fix the object to be processed in the mechanical manufacturing process so that it occupies the correct position for construction or inspection. It is also called a fixture. In a broad sense, any device used to quickly, conveniently and safely install the workpiece in any process can be called a fixture. Friction stir welding uses friction heat and plastic deformation heat as welding heat sources. The friction stir welding process is that a stirring needle of a cylinder or other shape (such as a threaded cylinder) is inserted into the joint of the workpiece, and the high-speed rotation of the welding head causes it to rub against the workpiece material, thereby raising the temperature of the material at the connection part and softening it. At the same time, the material is stirred and rubbed to complete the welding. At the same time, a fixture is needed in the process of friction stir welding to ensure that the workpiece material does not shake during the processing.

[0003] Common fixtures usually consist of positioning elements (to determine the correct position of the workpiece in the fixture), clamping devices, tool guiding elements (to determine the relative position of the tool and the workpiece or to guide the direction of the tool), indexing devices (to enable the workpiece to complete the processing of several stations in one installation, and there are two types: rotary indexing devices and linear indexing devices), connecting elements, and clamp bodies (clamp bases). The clamping device fixes the workpiece on the top of the workbench for friction stir welding. This is a common way to use the fixture structure holes. Traditional friction stir welding fixtures clamp the workpiece on the top of the workbench for friction stir welding. During the friction stir welding process, debris will be generated in the surrounding area, which is not easy to collect and will affect the personal safety of nearby workers. Some friction stir welding fixtures have suction structures added to the periphery to absorb the sputtered debris and guide the debris into the interior of the collection device. However, in this method, since the temperature of the sputtered waste chips generated during welding is too high, after a certain period of time after reaching the inside of the collection device, it will cause certain damage to the inside of the collection device. Therefore, a stir friction welding fixture that can handle welding waste chips is proposed. Summary of the invention

The suction plate moves on the top of the workbench body and approaches the periphery of the workpiece to be processed. The vacuum machine is started and the suction plate is used to make the suction hole of the suction pipe generate suction, so that the waste chips generated by the welding of the workpiece are sucked in and introduced into the interior of the collection box along the heat-resistant material guide pipe. The water pump sucks out the coolant at the bottom of the inner cavity of the collection box, and injects it into the interior of the spray rod through the outlet pipe, and sprays it out through the spray hole of the spray rod to cool the welding waste chips entering the collection box, thereby preventing the welding waste chips from damaging the inner cavity of the collection box due to their own high temperature.
