Description

Technical Field

[0001] The utility model specifically relates to the technical field of tooling fixtures, in particular to an adjustable tooling fixture that can be used in conjunction with a robot for welding. Background Art

[0002] Metal round tubes are one of the most common structures in industrial production and daily life. For example, trash cans, exhaust pipes, tea barrels, range hood pipes, lampshades, etc. are all formed by rolling sheet metal into a round shape and then welding it.

[0003] The current production process of metal round tubes is roughly as follows: first, according to the size of the round tube, the cutting machine cuts out the appropriate size of the plate, then the rolling machine rolls the plate into a cylindrical shape, and finally the welding equipment welds the joints to form a round tube structure.

[0004] Manual arc welding is one of the most common methods for welding sheet metal into pipes. During welding, the welding rod is first placed in contact with the joint of the pipe, then the arc is ignited by rapidly moving the rod away from the pipe. The high temperature generated by the arc melts the metal of the rod and the workpiece, forming a molten pool. As the rod moves, the molten pool cools and solidifies, forming a weld. However, welding efficiency is relatively low, and weld quality is significantly affected by the welder's skill level. Because the weld is manually operated, the appearance and internal quality of the weld are unstable. Furthermore, welder fatigue can occur during prolonged welding, affecting weld quality. Utility Model Content

The driving wheel is provided with a convex groove and is rotatably connected to the support wheel; the support wheel is rotatably connected to the support vertical plate through an axle pin in the gap of the support vertical plate.

[0009] As a further technical solution of the present invention, an extrusion wheel is provided in the gap of the extrusion plate and is rotatably connected to the extrusion plate through an axle pin. Slide rails are fixedly installed in the C-shaped shape on both sides of the fixed base plate. Multiple sliders are installed on the slide rails and are slidably connected thereto.

During the welding process, the motor can accurately control the rotation and angle of the workpiece as needed, allowing the manipulator to perform a full range of welding operations on the workpiece, significantly improving the overall quality of welding.

[0018] 3. In the present invention, the material storage box is located on the opposite side of the support frame on the operating table, which is convenient for the operator to perform material removal operations without affecting the welding work. At the same time, the design of the inclined baffle and the discharge port makes the material removal process safer and more convenient, reducing the risk of material spillage or personal injury caused by improper material removal operation, helping to improve the work efficiency of the operator, reduce safety accidents caused by improper operation, and ensure the smooth progress of the production process.
