[0022] It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0023] In addition, in the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0024] In this utility model, unless otherwise expressly specified or limited, terms such as "installed," "connected," "connect," and "fixed" should be understood broadly. For example, they can refer to fixed connections, detachable connections, or integration; they can refer to direct connections or indirect connections through an intermediate medium; they can refer to internal communication between two components or an interaction between two components. However, the phrase "direct connection" indicates that the two connected entities are not connected through an intermediate structure, but are connected to form a whole through a connecting structure. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0025] In the present invention, unless otherwise clearly specified and limited, the first feature "above" or "below" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0026] In this utility model, if Figure 1-3 As shown, a base plate fixing mechanism of a tower foot welding robot is provided, including a fixed bracket, the fixed bracket including mutually intersecting support rails 1, the support rails 1 being provided with a slide groove 2, the support rail 1 being provided with a lead screw 3 in the slide groove 2, the lead screw 3 comprising two lead screw segments with opposite rotation directions, the fixed bracket also including a lead screw slider 6 cooperating with the lead screw segment, the side wall of the slide groove 2 being provided with a limit plate 4 extending into the slot at the slot position, the fixing mechanism also including a fixed slider 5 arranged in the slide groove 2, the lead screw slider 6 and the fixed slider 5 being able to slide and cooperate in a direction perpendicular to the limit plate 4, the fixed slider 5 being able to abut against the limit plate 4 when sliding relative to the lead screw slider 6, and the fixed slider 5 being provided with a threaded hole on the side of the slot of the slide groove 2, the threaded hole deviating from the limit plate 4.

[0027] When the fixing mechanism of the present invention is in use, the screw 3 is rotated in advance so that the four screw sliders 6 drive the fixed slider 5 to move roughly to the four corner positions of the tower foot base plate, and the four corners of the tower foot base plate are respectively placed at the four screw slider 6 positions, and fixed through bolts and threaded holes. The bolts directly or indirectly press the tower foot base plate onto the limit plate 4 to achieve the fixation of the tower foot base plate on the fixed bracket. At this time, the fixed slider 5 is tightly fixed to the inner surface of the limit plate 4. Due to the sliding fit between the fixed slider 5 and the screw slider 6, the screw slider 6 will not be caused to provide lateral force to the screw 3 during the process of the fixed slider 5 pressing against the limit plate 4, thereby preventing the screw 3 from being deformed.

[0028] The threaded hole deviates from the limiting plate 4 , which can prevent the limiting plate 4 from blocking the threaded hole.

[0029] In a preferred embodiment, for the structure of the present invention, more specifically, the fixed slider 5 is provided with a sliding cavity 7 , and the lead screw slider 6 has a sliding portion 801 slidably arranged in the sliding cavity 7 .

[0030] In a preferred embodiment, for the structure of the present invention, more specifically, the bottom of the sliding cavity 7 is open, and the sliding portion 801 is inserted from bottom to top into the sliding cavity 7. As shown in the figure, this facilitates the assembly of the fixed slider 5 and the lead screw slider 6.

[0031] In the illustrated embodiment, more specifically, a through hole is formed on the side wall of the fixed slider 5 for the screw 3 to pass through, and the diameter of the through hole is larger than the outer diameter of the screw 3 .

[0032] In a preferred embodiment, for the structure of the present invention, to be more specific, the fixing mechanism also includes an upper pressing block 8 and a holding bolt 9, the upper pressing block 8 has a through hole, the upper pressing block has a holding portion, when the through hole corresponds to the threaded hole, the holding bolt 9 can pass through the through hole and be screwed into the threaded hole, and the holding portion can hold and fix the tower foot substrate.

[0033] As shown in the figure, the tower foot base plate can be pressed and fixed by the upper pressing block 8, so as to reduce the number of openings in the tower foot base plate.

[0034] In a preferred embodiment, for the structure of the present invention, more specifically, two upper pressing blocks 8 are provided, and the two upper pressing blocks 8 are respectively provided on two screw sections of a screw 3 .

[0035] As shown in the figure, two opposing corners of the tower base plate can be held in place by upper pressing blocks 8, while bolts can be inserted directly through holes in the other two corners to secure them. This reduces the number of holes required for the tower base plate at the two upper pressing blocks 8 and simplifies the alignment of the tower base plate through-holes with the threaded holes in the fixing slider 5 when securing the tower base plate.

[0036] In a preferred embodiment, for the structure of the present invention, more specifically, the upper pressing block 8 has a sliding portion 801 extending into the chute 2. As shown in the figure, this can prevent the fixed slider 5 from shaking laterally.

[0037] In a preferred embodiment, for the structure of the present invention, to be more specific, a positioning groove 10 is provided on the side of the upper pressure block 8 toward the center of the screw 3, and the positioning groove 10 passes through the bottom of the upper pressure block 8, and the groove wall of the positioning groove 10 is inclined inward from bottom to top; the groove wall of the positioning groove 10 forms the holding portion.

[0038] As shown in the figure, by setting it up in this way, after placing the tower base plate on the fixed bracket, the two upper pressing blocks 8 are first moved. During the movement of the two upper pressing blocks 8 towards each other, the groove walls of the positioning groove 10 gradually abut against the edges of the tower base plate corners and press the tower base plate tightly, thus automatically completing the centering of the tower base plate. Then, the other screw 3 is adjusted so that the threaded hole of the fixed slider 5 on the other screw 3 is aligned with the through hole of the tower base plate.

[0039] In a preferred embodiment, the structure of the present invention is further optimized in that an avoidance groove 11 is provided between the two groove walls of the positioning groove 10. As shown in the figure, the avoidance groove 11 is provided to prevent interference between the corner of the tower base plate and the two groove walls of the positioning groove 10.

[0040] In a preferred embodiment, a further optimized configuration of the structure of the present invention is that the through hole is configured as a countersunk through hole 12 .

[0041] The present invention also provides a tower foot welding robot including the aforementioned base plate fixing mechanism. Those skilled in the art may flexibly select existing structural components for other structural components of the tower foot welding robot, such as the robot body and the drive structure that primarily drives the fixed bracket for rotation and adjustment.
