Description

Technical Field

[0001] This utility model relates to the field of welding, specifically a friction stir welding tool magazine. Background Technology

[0002] During the welding process of friction stir welding equipment, it is necessary to change the welding tools to ensure the continuous welding work. Different tool holders are required for different welding conditions. To facilitate the use of tool holders by the welding spindle, the conventional strategy is to fix different types of tool holders in the tool magazine, and provide different tool holders for the friction stir welding equipment through the tool magazine.

[0003] Currently, conventional tool magazines, as described in application number "202410832016.2", rotate to move the tool holder to a set position for tool changing by the welding equipment. However, in friction stir welding, an angle is required between the stirring head axis and the workpiece plane to achieve tilted stirring welding. The tilt angle dynamically adjusts depending on the welding conditions. After adjustment, the welding equipment cannot smoothly align with the tool magazine for tool changing. To avoid this, each tool change requires adjusting the welding equipment's tilt angle to match the tool magazine's angle before changing the tool, and then adjusting the welding equipment's angle back to the set angle. This tool changing method is extremely inefficient and urgently needs a solution. Utility Model Content

[0014] As a further improvement of this utility model: a bayonet is formed by recessing the bottom surface of one section of the positioning groove downwards, and a positioning key is also protruding at the opening of the base to form a positioning engagement with the bayonet for positioning.

[0015] As a further embodiment of this utility model: connecting rods are symmetrically arranged on both sides of the arc-shaped opening of the base, the connecting rods are hinged to the base, and the hinge axis is arranged parallel to the axis of the arc-shaped opening of the base; one end of the two sets of connecting rods is the connecting end, and the other end of the two sets of connecting rods is the clamping end, and the clamping ends of the two sets of connecting rods elastically open and close to clamp and position the tool holder.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This utility model sets the tool magazine to a pitch-swing type, which can be adapted to the tilt angle of the welding equipment head assembly to meet different welding angle requirements. By turning the adjusting bolt, the tool magazine can be driven to swing around the rotating shaft under the push of the adjusting bolt, thereby fine-tuning the tilt angle of the tool magazine. The rotating shaft and the motor base are respectively arranged on both sides of the mounting base, so that the motor base can be arranged relatively adjacent to the mounting base. The swing adjustment of the tool magazine can be achieved with a shorter adjusting bolt, realizing the rapid adjustment of the tilt angle of the friction stir welding tool magazine and improving the tool changing efficiency.

[0020] 2. The positioning groove on the knife handle and the positioning boss on the knife clip of this utility model can achieve ring support and positioning of the knife handle. Combined with the positioning key and the positioning of the bayonet, the rotation of the knife handle can be stopped, preventing it from rotating after being clamped.

[0021] 3. This utility model uses the rollers on two sets of connecting rods to guide the tool holder, allowing it to smoothly enter the arc-shaped opening of the tool holder and applying an elastic clamping force to the tool holder, thereby reducing wear on the tool holder.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-3 In this embodiment of the utility model, a friction stir welding tool magazine includes a tool magazine 11 vertically arranged with the motor shaft of the tool magazine motor 11 arranged upward. A turntable 12 is coaxially arranged on the motor shaft, and tool clips 7 are evenly arranged on the turntable 12 along the circumference. The tool clips 7 are used to hold and fix the tool handle 8. A motor base 13 is provided at the bottom of the tool magazine motor 11.

[0033] The tool magazine 1 also includes a mounting base 16. Two sets of bearing housings are mounted on the bottom of the mounting base 16, and a rotating shaft 18 is installed between the two sets of bearing housings. The shaft of the rotating shaft 18 is parallel to the seat surface of the motor base 13. A swing adjustment block 15 is coaxially fixed on the rotating shaft 18. A limiting groove 17 is formed on the surface of the mounting base 16. The length of the limiting groove 17 is greater than the length of the swing adjustment block 15, and the width of the limiting groove 17 corresponds to the width of the swing adjustment block 15. When the rotating shaft 18 rotates, it drives the swing adjustment block 15 to swing within the limiting groove 17. The motor base 13 of the tool magazine motor 11 is fixed on the swing adjustment block 15, and is positioned after adjusting the pitch angle by swinging with the swing adjustment block 15. Preferably, two sets of swing adjustment blocks 15 and limiting grooves 17 are provided to provide bidirectional support and positioning for the motor base 13.

[0034] Adjusting bolts 14 are vertically installed at the four corners of the motor base 13. The adjusting bolts 14 are threaded into the motor base 13. After the length of the adjusting bolts 14 is adjusted, they abut against the mounting base 16, thereby positioning the pitch angle of the motor base 13.

[0035] The turntable 12 and the tool holder 7 are detachably mounted. The tool holder 7 includes a base 71 with an arc-shaped opening corresponding to the diameter of the tool holder 8, allowing the tool holder 8 to be inserted. Connecting rods 72 are symmetrically arranged on both sides of the arc-shaped opening on the base 71. A spring 73 is mounted on one end of each connecting rod 72, and a roller 74 is mounted on the other end. The rolling axis of the roller 74 is parallel to the axis of the arc-shaped opening of the base 71. The two sets of connecting rods 72 are hinged to the base 71, with the hinge point located in the middle of the connecting rods 72. The springs 73 of the two sets of connecting rods 72 are arranged perpendicular to the connecting rods 72, and the ends of the springs 73 are connected to the base 71. The springs 73 apply an outward elastic force to the ends of the two sets of connecting rods 72, causing the connecting rods 72 to perform an opening and closing clamping action. Under the elastic force of spring 73, the rollers 74 on the two connecting rods 72 produce an elastic clamping action on the tool holder 8.

[0036] To achieve better positioning of the tool holder 8, a positioning boss 75 is provided circumferentially at the arc-shaped opening of the tool holder 7, and a positioning key 76 is provided directly below the positioning boss 75. A positioning groove 81, corresponding to the size of the positioning boss 75, is provided circumferentially on the upper edge of the tool holder 8. A retaining slot 82 is recessed on the bottom surface of the positioning groove 81, and the retaining slot 82 corresponds to the size of the positioning key 76. When the tool holder 8 is clamped and positioned by the tool holder 7, the positioning boss 75 engages with the positioning groove 81, providing positioning support for the tool holder 8. The positioning key 76 is inserted into the retaining slot 82, achieving anti-rotation positioning of the tool holder 8.

[0037] The handle 8 has a threaded hole 83 along its radial direction, and a set screw is installed in the threaded hole 83. The bottom of the handle 8 is the mounting area, where a stirring head 84 can be installed. After the stirring head 84 is inserted into the handle 8 from bottom to top, the stirring head 84 is locked and positioned by the set screw.
