Description

Technical Field

[0001] This utility model relates to the field of friction stir welding equipment, and in particular to a device for removing aluminum chips from a friction stir welding head. Background Technology

[0002] During the welding of aluminum alloy products using static shoulder friction stir welding, aluminum shavings easily adhere to the static shoulder of the stirring head. In order not to affect subsequent welding production, it is necessary to clean the aluminum shavings.

[0003] In existing technologies, manual cleaning of aluminum shavings on the stationary shaft shoulder is often required after the machine is stopped, resulting in low work efficiency. Patent application CN202120018561 discloses an aluminum shaving trimming device for friction stir welding. The shearing blade adopts a cylindrical base that can be adapted to the outer surface of the stationary shaft shoulder, thereby using its internal annular blade to quickly remove aluminum shavings from the discharge hole. However, the annular blade can only be adapted to a single welding head, requiring high precision in the cleaning process, and is prone to uneven wear.

[0004] During friction stir welding of aluminum alloy products on the stationary shoulder, the aluminum shavings that adhere to the shoulder are usually large and fixed in position, making them difficult to remove. Aluminum shavings in other areas, however, fall off naturally without accumulating and therefore do not require cleaning. Therefore, using a ring-shaped cutting edge to clean these shavings on the stationary shoulder increases the frequency of use of that area, easily causing uneven wear, shortening its lifespan, and requiring frequent replacement of the cutting edge, thus increasing time and tool costs. Utility Model Content

[0005] The purpose of this invention is to provide a device for removing aluminum shavings from a friction stir welding head, which solves the problem of cleaning aluminum shavings in friction stir welding and improves reliability.

[0006] To achieve this objective, the present invention adopts the following technical solution: A friction stir welding head aluminum chip removal device includes: a base, a steering platform, a first fixing bolt, a motor, and a cutting tool. The steering platform is adjustable to rotate left and right on the base. The motor is adjustable to flip up and down above the steering platform. The cutting tool is mounted on the motor shaft. Mounting seats are provided on both sides of the motor on the steering platform. Fixing shafts are provided on both sides of the motor, passing through the corresponding mounting seats. The first fixing bolt is mounted on the mounting seat and points perpendicularly to the fixing shaft.

[0007] The cutting tool is a circular saw blade or a grinding disc.

[0008] The mounting base is provided with a guide hole corresponding to the fixed shaft.

[0009] The base is provided with a second fixing bolt pointing downwards.

[0010] The bottom surface of the steering platform is recessed in the center and a positioning hole is provided. The base is provided with a positioning post corresponding to the positioning hole.

[0011] The steering platform is provided with several arc grooves arranged in a ring around the positioning holes, and a third screw connected to the base is provided in the arc groove.

[0012] The base is provided with a threaded hole corresponding to the third screw.

[0013] The number of the circular arc grooves is 2 to 4.

[0014] The beneficial effects of this utility model are as follows: A friction stir welding head aluminum chip removal device introduces a motor with a cutting tool, and the angle of the motor can be adjusted so that the tool has a suitable cutting angle relative to the aluminum chips. After the friction stir welding has completed a certain period of work, the motor driving the tool to rotate can be started by the CNC device of the friction stir welding equipment, and the welding head and the tool move relative to each other, thereby efficiently and stably removing aluminum chips from the side of the stationary shoulder of the welding head. Moreover, the tool cleans the aluminum chips during the rotation process, avoiding the problem of uneven wear. It is more stable and reliable to use, has a low replacement frequency, and the cost of the tool is also relatively low. Attached Figure Description

[0015] Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 yes Figure 1 Exploded view. Detailed Implementation

[0016] The following is combined Figures 1 to 2 The technical solution of this utility model will be further illustrated through specific embodiments.

[0017] like Figure 1 The aluminum chip removal device for friction stir welding shown includes: a base 1, a turning platform 2, a first fixing bolt 6, a motor 4, and a cutter 5. The base 1 is provided with a second fixing bolt 9 pointing downwards. The base 1 is fixed to the worktable of the friction stir welding equipment by the second fixing bolt 9, and the structure is stable.

[0018] The steering platform 2 is mounted on the base 1 in a way that allows it to rotate left and right. A positioning hole 12 is recessed in the center of the bottom surface of the steering platform 2. A positioning post 14 corresponding to the positioning hole 12 is provided on the base 1 to center the steering platform 2, so that the steering platform 2 can rotate and adjust around the positioning post 14 to avoid offset problems.

[0019] The steering platform 2 is provided with several arc grooves 11 arranged in a ring around the positioning hole 12. A third screw 10 connected to the base 1 is provided in the arc groove 11 to fix the steering platform 2 after rotation adjustment and to prevent it from loosening.

[0020] The base 1 is provided with threaded holes 13 corresponding to the third screw 10, facilitating the tightening of the third screw 10. The number of arc grooves 11 is 2 to 4, such as... Figure 2 As shown, in this embodiment, three circular arc grooves 11 are arranged in a ring array, which does not affect the rotation adjustment of the turntable 2.

[0021] The motor 4 is mounted on the steering platform 2 in a way that allows it to be tilted up and down. The steering platform 2 is provided with mounting seats 3 located on both sides of the motor 4. The steering platform 2 and the mounting seats 3 can be made of an integrated steel structure with high strength.

[0022] Fixed shafts 7 are provided on both sides of the motor 4, passing through the corresponding mounting bases 3. In this embodiment, the mounting base 3 is provided with guide holes 8 corresponding to the fixed shafts 7 to support the rotational adjustment of the fixed shafts 7. The first fixing bolt 6 is provided on the mounting base 3 and points perpendicularly to the fixed shaft 7, such as... Figure 1 As shown, the first fixing bolt 6 is set on the top of the mounting base 3. The top of the mounting base 3 needs to be machined with a mounting hole that is perpendicular to the guide hole 8 to facilitate the installation of the first fixing bolt 6 and the tightening of the fixing shaft 7.

[0023] The cutting tool 5 is mounted on the rotating shaft of the motor 4. In this embodiment, the cutting tool 5 is a circular saw blade or grinding disc, which is low in cost. The rotation of the cutting tool 5 can be driven by the motor 4. After a period of work is completed by the friction stir welding, the motor 4 is started by the CNC device of the friction stir welding equipment, and the welding head and the cutting tool move relative to each other, thereby efficiently and stably removing aluminum chips. This makes the use more stable and reliable, avoids uneven wear of the cutting tool 5, and therefore reduces the replacement frequency and the cost of the cutting tool.

[0024] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
