Description

Technical Field

[0001] This invention relates to the field of gas-electric vertical welding technology, and in particular to a copper slider clamping device and a copper slider clamping method. Background Technology

[0002] Gas-shielded vertical welding is a highly efficient, automated gas-shielded welding method applied to butt joints of plates in vertical welding positions. The welding groove has a copper slider on its front side that forces the weld to form. The front side of the copper slider needs to be in contact with the surface of the steel plate in the welding area, requiring a certain amount of pressure (to ensure weld surface formation and prevent the flow of molten metal and slag), but the pressure cannot be too high (to avoid excessive friction between the two and ensure the copper slider slides evenly on the steel plate surface). The copper slider requires a clamping device to provide clamping force and upward sliding force, ensuring the relative position of the copper slider and the weld pool and enabling it to move upward synchronously and evenly with the welding carriage.

[0003] In existing copper slider clamping devices, when the welding groove is skewed or locally bent, the center position of the welding groove will change along the extension direction of the welding groove. In order to ensure that the center of the copper slider is aligned with the center of the welding groove, and to prevent the copper slider from being skewed, resulting in poor weld formation or even leakage of high-temperature liquid metal from the contact point between the copper slider and the steel plate surface, causing the welding process to be interrupted, the lateral position of the copper slider needs to be frequently adjusted manually, which is labor-intensive for operators.

[0004] Therefore, there is an urgent need for a copper slider clamping device and a copper slider clamping method to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a copper slider clamping device and a copper slider clamping method, so that the position of the copper slider can be kept aligned with the center of the welding bevel, ensuring the quality of the weld and reducing the labor intensity of the operators.

[0006] To achieve this objective, the present invention adopts the following technical solution: A copper slider clamping device includes a first connecting beam, a first driving assembly, a support member, a second driving assembly, a copper slider, a position characterization sensor, and a control module. The first drive component is disposed on the first connecting crossbeam; The support member is disposed on the first drive assembly, and the first drive assembly is capable of driving the support member to move along a first horizontal direction. The second drive component is disposed on the support member; The second drive assembly is used to press the copper slider along a second horizontal direction perpendicular to the first horizontal direction; The position characterization value sensor is disposed on the support member, and the position characterization value sensor is used to monitor parameters that characterize the relative position of the copper slider and the area to be welded along the first horizontal direction. The first drive component, the second drive component, and the position characterization sensor are all communicatively connected to the control module.

[0007] As an improvement to the above technical solution, the position characterization sensor is a laser rangefinder.

[0008] As an improvement to the above technical solution, the first drive component is a digital servo hydraulic cylinder.

[0009] As an improvement to the above technical solution, the copper slider clamping device further includes a guide member, one end of which is connected to the first connecting crossbeam, and the other end is provided with a guide ring, and the piston rod of the first driving assembly passes through the guide ring.

[0010] As an improvement to the above technical solution, the second drive component includes a hydraulic cylinder and a hydraulic pump, wherein the hydraulic pump is used to pump hydraulic oil into the hydraulic cylinder.

[0011] As an improvement to the above technical solution, the copper slider clamping device further includes a pressure sensor, which is installed on the hydraulic cylinder to monitor the cylinder pressure.

[0012] As an improvement to the above technical solution, the copper slider clamping device further includes a cross connector, which is disposed at the output end of the hydraulic cylinder. The copper slider has a cross groove on the side near the support member, and the cross connector is disposed in the cross groove and connected to the copper slider.

[0013] A method for clamping a copper slider, used in any of the copper slider clamping devices described above, comprising: The control module controls the second drive component to drive the copper slider to move along the second horizontal direction so that the copper slider abuts against the plate to be welded. During the vertical movement of the first connecting beam, the relative position of the copper slider and the area to be welded along the first horizontal direction is determined based on the monitoring results of the position characterization value sensor. When the relative position of the copper slider and the plate splice seam deviates, the control module controls the first driving component to drive the copper slider to move along the first horizontal direction so that the copper slider is facing the plate splice seam.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: The copper slider clamping device of the present invention includes a first connecting beam, a first driving assembly, a support member, a second driving assembly, a copper slider, a position characterizing sensor, and a control module. The first driving assembly is disposed on the first connecting beam. The support member is disposed on the first driving assembly, and the first driving assembly can drive the support member to move along a first horizontal direction. The second driving assembly is disposed on the support member. The second driving assembly is used to clamp the copper slider along a second horizontal direction perpendicular to the first horizontal direction. The position characterizing sensor is disposed on the support member and is used to monitor parameters that characterize the relative position of the copper slider and the plate to be welded along the first horizontal direction. The first driving assembly, the second driving assembly, and the position characterizing sensor are all communicatively connected to the control module. By setting the position characterizing sensor on the support member to monitor parameters that characterize the relative position of the copper slider and the plate to be welded along the first horizontal direction, the control module can timely control the first driving assembly to adjust the position of the support member along the first horizontal direction based on the monitoring results of the position characterizing sensor. This ensures that the position of the copper slider is aligned with the center of the welding bevel, guaranteeing weld quality and reducing the labor intensity of operators.

[0017] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0018] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; 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. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0019] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0020] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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 the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0021] In existing copper slider clamping devices, when the edges of the two plates to be welded are not completely parallel, the weld bevel may become skewed or locally bent. When the weld bevel is skewed or locally bent, the center position of the plate splice 100 along the vertical direction Z will change. In order to ensure that the center of the copper slider is aligned with the center of the weld bevel and to prevent the copper slider from being skewed, resulting in poor weld formation or even leakage of high-temperature liquid metal from the contact point between the copper slider and the steel plate surface, causing the welding process to be interrupted, the lateral position of the copper slider needs to be frequently adjusted manually, which is labor-intensive for operators.

[0022] like Figures 1-3As shown, this embodiment provides a copper slider clamping device, including a first connecting beam 1, a first driving assembly 2, a support member 3, a second driving assembly, a position characterizing sensor 6, and a control module 7. The first driving assembly 2 is disposed on the first connecting beam 1. The support member 3 is disposed on the first driving assembly 2, and the first driving assembly 2 can drive the support member 3 to move along a first horizontal direction X. The second driving assembly is disposed on the support member 3. The second driving assembly is used to clamp the copper slider 5 along a second horizontal direction Y perpendicular to the first horizontal direction X, that is, to clamp the copper slider 5 onto the plate to be welded. The position characterizing sensor 6 is disposed on the support member 3, and the position characterizing sensor 6 is used to monitor parameters that characterize the relative position of the copper slider 5 and the area to be welded along the first horizontal direction X. The first drive assembly 2, the second drive assembly, and the position characterization sensor 6 are all electrically connected to the control module 7. In this embodiment, the communication connection can be wired or wireless. The control module 7 controls the first drive assembly 2 to drive the support member 3 to move the copper slider 5 along the first horizontal direction X, based on the monitoring results from the position characterization sensor 6. In this embodiment, the plates to be welded include a first steel plate 10 and a second steel plate 20. The plate joint 100 is the gap between the first steel plate 10 and the second steel plate 20. The relative position of the copper slider 5 and the plate joint 100 along the first horizontal direction X, as described in this embodiment, refers to the relative position of the plate joint 100 and the copper slider 5 along the first horizontal direction X at a specific distance above the copper slider 5. Those skilled in the art will understand that when gas-electric vertical welding is used to weld the joint 100 of two plates, a ceramic backing 30 is placed on one side of the joint 100, and a copper slider 5 is placed on the other side of the joint 100. After the joint 100 is welded and cooled by the copper slider 5, a weld 200 is formed. The area to be welded is the joint 100 of the plates at a specific distance above the copper slider 5.

[0023] The copper slider clamping device of the present invention uses a position characterization value sensor 6 on the support member 3 to monitor parameters that characterize the relative position of the copper slider 5 and the plate to be welded along the first horizontal direction X. This allows the control module 7 to control the first drive component 2 to adjust the position of the support member 3 along the first horizontal direction X in a timely manner based on the monitoring results of the position characterization value sensor 6. This ensures that the position of the copper slider 5 is aligned with the center of the welding bevel, guarantees the quality of the weld, and reduces the labor intensity of the operator.

[0024] Optionally, the position characterization sensor 6 in this embodiment is a laser rangefinder. Specifically, in this embodiment, the characterization sensor 6 is a line laser sensor (also known as a laser profile scanner). By scanning and monitoring the profile of the plate joint 100 located at a specific distance above the copper slider 5, the relative position of the plate joint 100 located at a specific distance above the copper slider 5 and the characterization sensor 6 along the first direction X is determined. Since the relative positions between the characterization sensor 6 and the support member 3, and between the support member 3 and the copper slider 5, are determined, the relative position of the plate joint 100 located at a specific distance above the copper slider 5 and the characterization sensor 6 along the first horizontal direction X is also determined.

[0025] Optionally, in this embodiment, the first drive component 2 is a digital servo hydraulic cylinder (also known as a digital hydraulic cylinder). A digital servo hydraulic cylinder is a hydraulic transmission device that integrates a cylinder, a digital servo valve, a sensor, and a feedback control structure. This device uses a mechanically contoured lead screw to achieve displacement feedback, the frequency of electrical pulses corresponds to the movement speed, the number of pulses corresponds to the stroke, and the piston rod stroke control accuracy is high. Thus, through the cooperation of the first drive component 2 and the control module 7, it is easy to achieve precise control of the relative position between the copper slider 5 and the plate splice seam 100 along the first horizontal direction X.

[0026] Optionally, the copper slider clamping device further includes a guide member (not shown). One end of the guide member is connected to the first connecting beam 1, and the other end is provided with a guide ring. The piston rod of the first drive assembly 2 passes through the guide ring, and the axis of the guide ring extends along the first horizontal direction X. The guide member serves to guide and support the piston rod of the first drive assembly 2, and the guide ring bears the force along the second horizontal direction Y on the piston rod of the first drive assembly 2, thus preventing damage to the first drive assembly 2 from the force along the second horizontal direction Y. In other embodiments, other support methods can be used to guide and support the piston rod of the first drive assembly 2. Specifically, the guide includes a first connecting segment, a second connecting segment, and a third connecting segment. The first connecting segment and the third connecting segment both extend along the second horizontal direction Y, and the second connecting segment extends along the first horizontal direction X. One end of the first connecting segment is fixedly connected to the first connecting beam 1, one end of the second connecting segment is fixedly connected to the end of the first connecting segment away from the first connecting beam 1, and one end of the third connecting segment is fixedly connected to the end of the second connecting segment away from the first connecting segment. A guide ring is fixedly disposed at the end of the third connecting segment away from the second connecting segment. The first connecting segment and the third connecting segment are both located on the side of the second connecting segment closer to the first connecting beam 1.

[0027] Optionally, the second drive assembly includes a hydraulic cylinder 4 and a hydraulic pump, the hydraulic pump being used to pump hydraulic oil into the hydraulic cylinder 4. In this embodiment, the hydraulic cylinder 4 is a single-acting hydraulic cylinder.

[0028] Optionally, the copper slider clamping device also includes a pressure sensor mounted on the hydraulic cylinder 4 to monitor the cylinder pressure in the hydraulic drive chamber of the hydraulic cylinder 4. Both the hydraulic pump and the pressure sensor are communicatively connected to the control module 7. The pressure sensor monitors the cylinder pressure of the hydraulic cylinder 4, enabling the control module 7 to accurately control the cylinder pressure of the hydraulic cylinder 4 via the hydraulic pump, so that the pressure between the copper slider 5 and the plate to be welded meets the requirements of gas-electric vertical welding.

[0029] Optionally, the copper slider clamping device also includes a cross connector 8, which is located at the output end of the hydraulic cylinder 4. The copper slider 5 has a cross groove 51 on the side near the support member 3, and the cross connector 8 is located in the cross groove 51 and connected to the copper slider 5.

[0030] This embodiment also provides a copper slider clamping method for the aforementioned copper slider clamping device, comprising: Control module 7 controls the second drive component to drive the copper slider 5 to move along the second horizontal direction Y, so that the copper slider 5 abuts against the plate to be welded; During the movement of the first connecting beam 1 along the vertical direction Z, the relative position of the copper slider 5 and the area to be welded along the first horizontal direction X is determined according to the monitoring results of the position characterization value sensor 6. When the relative position of the copper slider 5 and the area to be welded deviates, the control module 7 controls the first driving component 2 to drive the copper slider 5 to move along the first horizontal direction X so that the copper slider 5 is facing the area to be welded, that is, so that the plate splice seam 100 is located in the middle of the copper slider 5 along the first horizontal direction X. When the relative position of the copper slider 5 and the area to be welded deviates, that is, when the plate splice seam 100 deviates from the middle of the copper slider 5 along the first horizontal direction X.

[0031] In this embodiment of the copper slider clamping method, the control module 7 controls the first drive component 2 to adjust the position of the support 3 along the first horizontal direction X in a timely manner according to the monitoring results of the position characterization value sensor 6, so that the position of the copper slider 5 can be kept aligned with the center of the welding groove, ensuring the quality of the weld and reducing the labor intensity of the operator.

[0032] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
