Description

Technical Field

[0001] This utility model relates to the field of metal processing, and in particular to a rotation locking structure for a tower foot welding robot. Background Technology

[0002] As an important load-bearing component of the iron tower, the tower feet have high requirements for welding quality and stability. Currently, some factories use dedicated tower foot welding robots to automatically weld the tower feet. For example, the automatic welding device for tower feet robot disclosed in application number CN202221056508.X uses a cross to fix the initially spot-welded tower feet, and then the robot body welds and fixes the tower feet. During the welding process of the robot body, the cross is rotated by a rotary motor and a rotary reduction motor to adjust the position of the tower feet.

[0003] Currently, existing automated welding devices for tower legs using robots have a structure that secures the tower legs. This structure includes two mounting bases, a rotatable crossbar between the bases, and a geared motor on one of the bases to drive the crossbar's rotation. After the crossbar's position is adjusted, it is typically secured using a self-locking mechanism on the geared motor. However, this method is problematic because the crossbar is often quite long and the tower leg is heavy. The single-sided locking mechanism of the retrieval motor bears a significant load, making it difficult to stably secure the crossbar. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a rotation locking structure for a tower foot welding robot, which can stably lock and fix the end of the fixed support. Moreover, the locking structure is easy to implement, effectively solving the existing problems.

[0005] To address the aforementioned problems, this utility model provides a rotation locking structure for a tower foot welding robot. The tower foot welding robot includes two opposing mounting seats, a fixed bracket rotatably disposed between the two mounting seats, a drive component mounted on one of the fixed brackets, and a controller. The controller can control the drive component to rotate the fixed bracket. The locking structure includes a brake disc assembly disposed in the mounting seat on the opposite side of the drive component. The brake disc assembly includes a disc body coaxially connected to the fixed bracket, a caliper cooperating with the disc body, and an electric drive component driving the caliper. The electric drive component is electrically connected to the controller.

[0006] Furthermore, the caliper is selected from mechanical calipers or hydraulic calipers, and the locking structure also includes a conduit and a push rod connected to the caliper. The push rod can move between a first position and a second position. When the push rod is in the first position, it can drive the caliper to fix the disc body through the conduit. When the push rod is in the second position, it can drive the caliper to release the disc body. The electric drive unit can drive the push rod to move between the first position and the second position.

[0007] Furthermore, the electric drive component includes a telescopic rod, which can be configured as an electric telescopic rod or a pneumatic telescopic rod.

[0008] Furthermore, the telescopic rod has a push plate at its telescopic end, and the telescopic rod can drive the push rod to move from the second position toward the first position through the push plate.

[0009] Furthermore, the locking structure also includes a push rod seat, the push rod is mounted on the push rod seat, and the push rod seat is threadedly connected to the mounting base.

[0010] Furthermore, the locking structure also includes a connecting rope connected to the push rod. One end of the connecting rope, away from the push rod, extends out of the outer side of the mounting base. The outer side of the mounting base is provided with a locking part. After the connecting rope drives the push rod to move from the second position to the first position, it can be fixed by the locking part.

[0011] Furthermore, the locking part includes a lock lug with a notch; the outer end of the connecting rope is provided with a locking block, and the locking block can abut against and limit the movement of the connecting rope when it passes through the notch.

[0012] Furthermore, the locking lug has a limiting flange at its edge away from the mounting base.

[0013] Furthermore, the push rod seat is equipped with a position sensor, which is triggered when the push rod moves to the first position. The position sensor is connected to the control system.

[0014] Furthermore, the locking structure also includes an indicator light disposed on the outside of the mounting base, the indicator light being connected to the controller.

[0015] The beneficial effect of this utility model is that it can stably lock and fix the end of the fixed bracket, and the locking structure is easy to implement, effectively solving the existing problems. Attached Figure Description

[0022] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0023] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may 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.

[0024] Furthermore, it should be understood in the description of this utility model that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral unit; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. However, specifying a direct connection indicates that the two main bodies at the connection point are not connected by an intermediate structure, but are simply connected to form a whole through a connecting structure. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0026] In this utility model, unless otherwise expressly specified and limited, the first feature "on" or "below" the second feature may be in direct contact with the first and second features, or indirect contact through an intermediate medium. In the description of this specification, references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0027] In this utility model, such as Figure 1-4 As shown, a rotation locking structure for a tower welding robot is provided. The tower welding robot includes two oppositely arranged mounting bases 1, a fixed bracket 2 rotatably disposed between the two mounting bases 1, a drive component 3 installed on one of the fixed brackets 2, and a controller. The controller can control the drive component 3 to drive the fixed bracket 2 to rotate. The locking structure includes a brake disc assembly disposed in the mounting base 1 on the opposite side of the drive component 3. The brake disc assembly includes a disc body 4 coaxially connected to the fixed bracket 2, a caliper cooperating with the disc body 4, and an electric drive component 3 driving the caliper. The electric drive component 3 is electrically connected to the controller.

[0028] In use, when the rotating locking structure of this invention requires locking the fixed bracket 2, the controller stops the rotation of the drive component 3. Simultaneously, the controller controls the electric drive component 3 to drive the caliper locking disc 4, thereby completing the locking and fixing of the fixed bracket 2. This invention achieves two-end fixing of the fixed bracket 2 by driving and locking one end of the fixed bracket 2 via the drive component 3 and locking the other end via the brake disc assembly. This not only provides stable locking of the fixed bracket 2 but also reduces the load on the self-locking mechanism of the drive component 3. Furthermore, the brake disc assembly can be used to lock the fixed bracket 2 at one end during disassembly and maintenance of the drive component 3.

[0029] In a preferred embodiment, more specifically regarding the structure of this utility model, the caliper 5 is selected from mechanical caliper 5 or hydraulic caliper 5, and the locking structure further includes a conduit 6 and a push rod 7 connected to the caliper 5. The push rod 7 can move between a first position and a second position. When the push rod 7 is in the first position, it can drive the caliper 5 to fix the disc body 4 through the conduit 6. When the push rod 7 is in the second position, it can drive the caliper 5 to release the disc body 4. The electric drive unit 3 can drive the push rod 7 to move between the first position and the second position.

[0030] This allows the brake disc assembly to utilize existing disc brake components, such as the disc body 4 and caliper 5, cable 6 and push rod 7 from electric vehicles and motorcycles, such as hydraulic disc brake components or cable-operated disc brake components. This facilitates assembly and maintenance.

[0031] As shown in the figure, the disc body is connected to the rotating shaft of the fixed bracket and is located inside the mounting base. The push rod 7 is installed on the inner side wall of the mounting base adjacent to the disc body.

[0032] In a preferred embodiment, more specifically regarding the structure of this utility model, the electric drive component 3 includes a telescopic rod 8, which is configured as an electric telescopic rod 8 or a pneumatic telescopic rod 8.

[0033] In embodiments employing an electrically operated telescopic rod 8, the controller is directly connected to the electric telescopic rod 8 to control its extension and retraction. In embodiments employing a pneumatic telescopic rod 8, the controller is connected to a solenoid valve in the pneumatic pipeline of the pneumatic telescopic rod 8 to control its extension and retraction.

[0034] This utility model uses an electric telescopic rod 8 or a pneumatic telescopic rod 8 as the electric drive component 3, which makes it easy to obtain the electric drive component 3, thereby further facilitating assembly and maintenance.

[0035] In a preferred embodiment, specifically regarding the structure of this utility model, the telescopic end of the telescopic rod 8 is provided with a push plate 9. The telescopic rod 8 can drive the push rod 7 to move from the second position toward the first position via the push plate 9. As shown in the figure, the telescopic rod 8 pushes the push rod 7 through the push plate 9 to brake. When the telescopic rod 8 drives the push plate 9 away from the push rod 7, the disc body 4 can be unlocked by resetting the push rod 7 or the caliper 5. This facilitates the coordination and conversion between the linear movement of the telescopic rod 8 and the swinging movement of the push rod 7.

[0036] In a preferred embodiment, more specifically regarding the structure of this utility model, the locking structure further includes a push rod seat 10, the push rod 7 is mounted on the push rod seat 10, and the push rod seat 10 is threadedly connected to the mounting base 1.

[0037] In a preferred embodiment, specifically regarding the structure of this invention, the locking structure further includes a connecting rope 11 connected to the push rod 7. One end of the connecting rope 11, away from the push rod 7, extends outward from the outer side of the mounting base 1. The outer side of the mounting base 1 is provided with a locking part. After the connecting rope 11 moves the push rod 7 from the second position to the first position, it can be fixed by the locking part. As shown in the figure, by providing the connecting rope 11, this invention allows for manual dragging of the connecting rope 11 to fix it to the locking part when the telescopic rod 8 malfunctions or when it is necessary to lock the disc 4 for an extended period. This achieves a mechanical manual brake.

[0038] As shown in the figure, the telescopic rod and the push rod are installed on the inner side wall of the mounting base adjacent to the chuck. The inner side wall of the mounting base has through holes at corresponding positions. The connecting rope passes through the through holes and extends out to the outside of the mounting base.

[0039] In the illustrated embodiment, for the structure of this utility model, more specifically, the locking part includes a lock lug 12, the lock lug 12 is provided with a notch 14; the outer end of the connecting rope 11 is provided with a locking block 13, and when the connecting rope 11 passes through the notch 14, the locking block 13 can abut and limit the locking position with the lock lug 12.

[0040] As shown in the figure, when manual braking is required, the locking block 13 can be held by hand so that the connecting rope 11 passes through the notch 14 and the locking block 13 abuts against the top surface of the locking lug 12.

[0041] In a preferred embodiment, specifically regarding the structure of this utility model, the locking lug 12 has a limiting flange 15 at its edge away from the mounting base 1. As shown in the figure, the outer edge of the locking lug 12 has an upwardly folded limiting flange, which can be used to limit the locking block 13 to prevent the locking block 13 from detaching from the locking lug 12.

[0042] In a preferred embodiment, more specifically regarding the structure of this utility model, the push rod seat 10 is provided with a position sensor 16, which is triggered when the push rod 7 moves to the first position, and the position sensor 16 is connected to the control.

[0043] By setting up a position sensor 16, when the controller controls the telescopic rod 8 to drive the push rod 7 to lock the disc 4, the position sensor 16 can be used to determine whether the push rod 7 has moved to the correct position, so as to facilitate the control of the extension and retraction of the telescopic rod 8.

[0044] Preferably, the position sensor 16 is a contact position sensor 16.

[0045] In a preferred embodiment, specifically regarding the structure of this invention, the locking structure further includes an indicator light 17 disposed on the outside of the mounting base 1, the indicator light 17 being connected to the controller. This allows the controller to control the indicator light 17 to change when the controller controls the telescopic rod 8 to drive the push rod 7 to lock the disc 4, and the position sensor 16 sends a triggered signal, thus indicating the braked state of the disc 4.

[0046] It should be noted that the improvement of this utility model lies in the rotation locking structure of the tower foot welding robot. No restrictions are placed on the modification of other structural components of the tower foot welding robot, and those skilled in the art can flexibly choose to implement them. For the controller, a PLC controller is preferred. This utility model limits the use of the controller to the extension and retraction control of the telescopic rod 8, the signal acquisition of the position sensor 16, and the control of the indicator light 17. These are functions that can be easily implemented by existing controllers and constitute prior art references to the controller. Controllers with these functions can also be directly purchased. Therefore, this utility model does not make any methodological improvements to the controller.

[0047] The various embodiments in this specification are described in a progressive manner. Similar or identical parts between embodiments can be referred to interchangeably. Each embodiment focuses on describing the differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions in the method embodiments.

[0048] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
