[0020] Please see Figure 1-5 This utility model provides a technical solution: a screw alignment friction welding machine, including a frame, the frame including a first mounting frame 101 arranged along the Z-axis direction and a second mounting frame 102 arranged along the Y-axis direction, and further including a Z-axis moving module 400 connected to the first mounting frame 101 for driving the welding equipment 600 to move up and down, a Y-axis moving module 200 connected to the second mounting frame 102, and a workpiece fixing device 500, wherein the workpiece fixing device 500 is located below the driving welding equipment 600 and is connected to the X-axis moving module 300, the X-axis moving module 300 is connected to the Y-axis moving module 200, and is used to adjust the position of the workpiece fixing device 500. By adopting the above structural design, the screw alignment friction welding machine adjusts the lifting and lowering movement of the welding equipment 600 by setting the Z-axis moving module 400, and adjusts the position of the workpiece fixing device 500 by setting the Y-axis moving module 200 and the X-axis moving module 300, thereby achieving relatively automated and accurate alignment of the screw to the workpiece to be welded position, greatly improving the alignment accuracy and thus ensuring the welding quality.

[0021] In this embodiment, the Y-axis moving module 200, X-axis moving module 300 and Z-axis moving module 400 adopt the same structural design, all of which are ball screw modules.

[0022] By designing the X-axis moving module, Y-axis moving module, and Z-axis moving module into a universal structure, mass production can be carried out in a single batch, reducing manufacturing costs and facilitating widespread use; and the Y-axis moving module 200 is mounted on the second mounting bracket 102, while the Z-axis moving module 400 is fixedly mounted on the first mounting bracket 101, improving connection stability.

[0023] In this embodiment: the Z-axis moving module 400 includes a pair of slide rails 401 parallel to each other on the first mounting bracket 101, a slider slidably connected to the slide rails 401, a rotatable lead screw 403, one end of the lead screw 403 being drive-connected to a drive motor 402, and a nut seat movably sleeved on the lead screw 403. The Z-axis moving module 400 also includes a foldable and retractable dust cover 405 arranged along the length of the slide rails 401. The Y-axis moving module 200, X-axis moving module 300, and Z-axis moving module 400 all adopt ball screw modules, which can meet the requirements of friction welding machines for high precision, high speed, and high rigidity, and improve processing accuracy and efficiency. By setting the foldable and retractable dust cover 405, dust, debris, metal slag, and other contaminants are prevented from entering the nut, avoiding severe wear of components such as balls, screws, and nuts due to contamination, thus reducing the motion accuracy and service life of the mechanism.

[0024] In this embodiment: the welding equipment 600 includes a base plate 601, which is connected to the slider and nut seat of the Z-axis moving module 400; a housing 602 fixedly connected to the base plate 601; and a welding spindle 603 rotatably mounted on the housing 602. The upper end of the welding spindle 603 is connected to the output shaft of the rotary motor 605, and the lower end of the welding spindle 603 is connected to a welding head 604 for clamping screws and performing rotary friction welding. By adopting the above structural design, the output shaft of the rotary motor 605 and the welding spindle 603 are connected in a transmission connection, driving the welding head 604 at the lower end of the welding spindle 603 to rotate. This causes the screw clamped on the welding head 604 to rotate at high speed, while the Z-axis moving module 400 drives the entire welding equipment 600 to move downward, applying downward pressure to the aligned workpiece to be welded, thus achieving a firm weld between the screw and the workpiece.

[0025] In this embodiment, a cooling fan 700 is installed on the top of the housing 602. By providing a cooling fan 700 on the housing 602, heat dissipation can be achieved for the components inside the housing 602.

[0026] In this embodiment: the workpiece fixing device 500 includes a U-shaped seat 501 connected to the slider and nut seat of the X-axis moving module 300. A processing table 502 is detachably connected to the middle of the U-shaped seat 501. A clamp 503 for holding the workpiece to be welded is provided in the center of the processing table 502. In use, the workpiece to be welded is clamped on the clamp 503. The workpiece is moved to the bottom of the welding equipment 600 by the Y-axis moving module 200 and the X-axis moving module 300. The rotary motor 605 is started. The rotary motor 605 drives the screw clamped on the welding head 604 to rotate at high speed. At the same time, the Z-axis moving module 400 drives the entire welding equipment 600 to move downward, applying downward pressure to the aligned workpiece to be welded, thus realizing a firm weld between the screw and the workpiece to be welded.

[0027] In this embodiment, the first mounting bracket 101 is fixedly connected to the tail of the second mounting bracket 102, and the bottom of the second mounting bracket 102 is provided with a plurality of mounting holes 103. By adopting the above structural design, the first mounting bracket 101 and the second mounting bracket 102 can provide stable support for the device, ensuring the stable operation of the equipment, and the mounting holes 103 facilitate the installation and fixing of the welding device.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
