Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to a welding production line. Background Technology

[0002] Traditional welding operations rely heavily on manual operation or semi-automated equipment, which is not only inefficient but also makes it difficult to guarantee the consistency and accuracy of weld quality. In existing technologies, most welding equipment is only equipped with one type of fixture. When producing workpieces of other sizes, the fixture must be disassembled and reinstalled, a process that is not only time-consuming and labor-intensive but also significantly impacts production efficiency. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a welding production line that can improve production efficiency and reduce production costs.

[0004] A welding production line according to a first aspect of the present invention includes:

[0005] The clamping station includes a base, a first rotary seat and a second rotary seat. The first rotary seat and the second rotary seat are respectively disposed at both ends of the base. The base is provided with a first machining plane and a second machining plane. The first machining plane is provided with a first workpiece clamping mechanism and the second machining plane is provided with a second workpiece clamping mechanism.

[0006] The welding station is equipped with a welding robotic arm, which is positioned toward the clamping station to weld workpieces on the first processing plane or the second processing plane.

[0007] According to an embodiment of the present invention, a welding production line has at least the following beneficial effects: by setting a first rotating seat and a second rotating seat at both ends of the machine base, and configuring a first processing plane and a second processing plane on the machine base, each processing plane is equipped with an independent workpiece clamping mechanism, which can adapt to workpieces of different specifications and sizes, greatly improving the continuity and efficiency of production; since two different first processing planes and second processing planes are set, the production line does not need to stop to change fixtures during operation, greatly improving the flexibility and response speed of the production line; the first workpiece clamping mechanism and the second workpiece clamping mechanism can ensure the precise positioning and high stability of the workpiece during the welding process, which helps to reduce welding errors, improve welding quality, and meet the needs of high-quality welding operations; the welding robot arm is set towards the clamping station, which can automatically align and weld the workpiece located on the first processing plane or the second processing plane, realizing the automation of the welding process, which not only reduces the need for manual intervention, but also reduces the labor intensity of operators, further improving work efficiency and safety.

[0008] According to some embodiments of this utility model, the first rotating seat and the second rotating seat are driven to be located at both ends of the machine base, and the first rotating seat and the second rotating seat simultaneously drive the machine base to rotate. The welding production line can quickly adapt to the processing needs of workpieces of different specifications and complexities. Whether it is simple planar welding or complex three-dimensional structure welding, it can be completed efficiently by adjusting the angle of the machine base, increasing the versatility and applicability of the equipment.

[0009] According to some embodiments of this utility model, the first processing plane is provided with a first mounting base composed of multiple independent mounting plates, and the second processing plane is provided with a second mounting base composed of multiple independent mounting plates, wherein the mounting plates of the first mounting base and the second mounting base are arranged in an alternating spatial distribution. When welding is required on the back side of the workpiece on the first processing plane, the operation can be performed from the front side of the second processing plane, greatly improving the operational flexibility and accessibility of the welding robot arm, ensuring that welding of even complex shapes or hard-to-access parts can be completed efficiently.

[0010] According to some embodiments of this utility model, the first mounting base and the second mounting base are installed on the machine base via a quick-release structure. This can significantly reduce the time required to change tooling fixtures. When it is necessary to switch to producing workpieces of different specifications or types, operators can quickly disassemble and install the base, thereby effectively improving the changeover efficiency of the production line and reducing downtime.

[0011] According to some embodiments of this utility model, the machine base is provided with graduations along its length. This facilitates precise positioning of the workpiece or fixture, ensuring the workpiece is in the optimal welding position during both initial installation and subsequent adjustments, thereby improving welding accuracy.

[0012] According to some embodiments of this utility model, the welding station is further provided with a guide rail, which is arranged parallel to one side of the machine base and extends in the same direction as the length of the machine base. The welding robotic arm is movably mounted on the guide rail. The presence of the guide rail ensures the stability and accuracy of the welding robotic arm during movement. By precisely controlling the movement of the robotic arm along the guide rail, high-precision control of the welding path can be achieved, thereby improving welding quality and reducing welding defects caused by positional deviations.

[0013] According to some embodiments of this utility model, the first workpiece clamping mechanism and the second workpiece clamping mechanism are provided with multiple pneumatic clamping units. Each pneumatic clamping unit includes a clamping arm, a drive cylinder, and a hinge structure. The end of the clamping arm is provided with a workpiece contact portion. The piston rod end of the drive cylinder contacts and engages with the transmission end of the clamping arm. The hinge structure is located in the middle of the clamping arm. By providing multiple pneumatic clamping units, the first and second workpiece clamping mechanisms can provide more uniform and powerful clamping force. Each pneumatic clamping unit works independently, enabling precise clamping of workpieces of different shapes and sizes, ensuring that the workpiece remains stable throughout the welding process.

[0014] According to some embodiments of this utility model, the distance between the center of the hinge structure and the center of the drive cylinder is A, and the distance between the center of the hinge structure and the center of the workpiece contact portion is B, satisfying: 1.2A≤B≤1.5A. This ensures clamping force while preventing deformation of the clamping arm, thus ensuring the service life of the equipment.

[0015] According to some embodiments of this utility model, the clamping station further includes a gas distribution valve, which is electrically connected to the drive cylinder. Using a gas distribution valve to manage the gas supply to multiple drive cylinders can greatly simplify the complexity of the control system. Compared to controlling each cylinder individually, it reduces the number of valves and pipes required, lowers the risk of system failure, and makes maintenance easier.

[0016] According to some embodiments of this utility model, the clamping station further includes a machine base, with the first rotary seat and the second rotary seat fixedly mounted on the machine base. A leveling mechanism is also provided at the bottom of the machine base. The leveling mechanism includes a first fine-tuning module disposed below the first rotary seat and a second fine-tuning module disposed below the second rotary seat. This avoids welding defects caused by tilting or instability and helps reduce the impact of uneven ground or external vibrations on welding accuracy.

[0017] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0027] Reference Figures 1 to 3 A welding production line, comprising:

[0028] The clamping station includes a base 120, a first rotary seat 100 and a second rotary seat 110. The first rotary seat 100 and the second rotary seat 110 are respectively disposed at both ends of the base 120. The base 120 is provided with a first machining plane 130 and a second machining plane 230. The first machining plane 130 is provided with a first workpiece clamping mechanism and the second machining plane 230 is provided with a second workpiece clamping mechanism.

[0029] The welding station is equipped with a welding robot arm, which is positioned toward the clamping station to weld workpieces on the first processing plane 130 or the second processing plane 230.

[0030] By setting a first rotating seat 100 and a second rotating seat 110 at both ends of the base 120, and configuring a first processing plane 130 and a second processing plane 230 on the base 120, each processing plane is equipped with an independent workpiece clamping mechanism, which can adapt to workpieces of different specifications and sizes, greatly improving the continuity and efficiency of production. Since two different first processing planes 130 and second processing planes 230 are set, the production line does not need to stop to change fixtures during operation, greatly improving the flexibility and response speed of the production line. The first workpiece clamping mechanism and the second workpiece clamping mechanism can ensure the precise positioning and high stability of the workpiece during the welding process, which helps to reduce welding errors, improve welding quality, and meet the needs of high-quality welding operations. The welding robot arm is set towards the clamping station, which can automatically align and weld the workpiece located on the first processing plane 130 or the second processing plane 230, realizing the automation of the welding process. This not only reduces the need for manual intervention, but also reduces the labor intensity of operators, further improving work efficiency and safety.

[0031] The first rotating seat 100 and the second rotating seat 110 are driven at both ends of the machine base 120, and the first rotating seat 100 and the second rotating seat 110 simultaneously drive the machine base 120 to rotate. The welding production line can quickly adapt to the processing needs of workpieces of different specifications and complexities. Whether it is simple planar welding or complex three-dimensional structure welding, it can be completed efficiently by adjusting the angle of the machine base 120, which increases the versatility and applicability of the equipment.

[0032] The first processing plane 130 is provided with a first mounting base 140 composed of multiple independent mounting plates, and the second processing plane 230 is provided with a second mounting base composed of multiple independent mounting plates. The mounting plates of the first mounting base 140 and the second mounting base are arranged in an alternating spatial distribution. When welding is required on the back of the workpiece on the first processing plane 130, the operation can be performed from the front of the second processing plane 230, which greatly improves the operational flexibility and accessibility of the welding robot arm, ensuring that welding of even complex shapes or hard-to-access parts can be completed efficiently.

[0033] The first mounting base 140 and the second mounting base are mounted on the machine base 120 via a quick-release structure. This significantly reduces the time required to change tooling fixtures. When switching production to produce different specifications or types of workpieces, operators can quickly disassemble and install the bases, thereby effectively improving production line changeover efficiency and reducing downtime. It is understood that the quick-release structure can be a snap-fit ​​structure, a bolt quick-lock structure, or a magnetic quick-release structure.

[0034] The machine base 120 has graduations along its length. This facilitates precise positioning of the workpiece or fixture, ensuring the workpiece is in the optimal welding position during both initial installation and subsequent adjustments, thereby improving welding accuracy.

[0035] The welding station is also equipped with a guide rail 240, which is parallel to one side of the base 120 and extends in the same direction as the length of the base 120. The welding robot arm can be movably mounted on the guide rail 240. The presence of the guide rail 240 ensures the stability and accuracy of the welding robot arm during movement. By precisely controlling the movement of the robot arm along the guide rail 240, high-precision control of the welding path can be achieved, thereby improving welding quality and reducing welding defects caused by positional deviations.

[0036] The first and second workpiece clamping mechanisms are equipped with multiple pneumatic clamping units 150. Each pneumatic clamping unit 150 includes a clamping arm 210, a drive cylinder 200, and a hinge structure 220. The end of the clamping arm 210 has a workpiece contact portion, and the piston rod end of the drive cylinder 200 contacts and engages with the transmission end of the clamping arm 210. The hinge structure 220 is located in the middle of the clamping arm 210. By providing multiple pneumatic clamping units 150, the first and second workpiece clamping mechanisms can provide a more uniform and powerful clamping force. Each pneumatic clamping unit 150 works independently and can accurately clamp workpieces of different shapes and sizes, ensuring that the workpiece remains stable throughout the welding process.

[0037] The distance A between the center of hinge structure 220 and the center of drive cylinder 200, and the distance B between the center of hinge structure 220 and the center of the workpiece contact part, satisfying: 1.2A≤B≤1.5A. This ensures clamping force while preventing deformation of clamping arm 210, thus ensuring the service life of the equipment.

[0038] The clamping station also includes a gas distribution valve 190, which is connected to the drive cylinder 200. Using the gas distribution valve 190 to manage the gas supply to multiple drive cylinders 200 can greatly simplify the complexity of the control system. Compared with controlling each cylinder individually, it reduces the number of valves and pipes required, lowers the risk of system failure, and makes maintenance easier.

[0039] The clamping station also includes a machine base 160, with a first rotary seat 100 and a second rotary seat 110 fixedly mounted on the machine base 160. A leveling mechanism is also provided at the bottom of the machine base 160. The leveling mechanism includes a first fine-tuning module 170 located below the first rotary seat 100 and a second fine-tuning module 180 located below the second rotary seat 110. This avoids welding defects caused by tilting or instability and helps reduce the impact of uneven ground or external vibrations on welding accuracy.

[0040] This embodiment provides an advanced and fully functional welding production line. The welding production line includes a clamping station and a welding station, wherein the clamping station further includes components such as a base 120, a first rotating seat 100, a second rotating seat 110, multiple pneumatic clamping units 150, a gas distribution valve 190, and a leveling mechanism.

[0041] A first machining plane 130 and a second machining plane 230 are provided on the base 120, each equipped with an independent workpiece clamping mechanism. A first rotary seat 100 and a second rotary seat 110 are located at opposite ends of the base 120 and are synchronously driven to rotate the base 120 via a transmission device. A leveling mechanism is provided below the rotary seats, including a first fine-tuning module 170 and a second fine-tuning module 180. The first mounting base 140 and the second mounting base are composed of multiple independent mounting plates arranged in an alternating pattern to ensure that the workpiece can be accessed from the other side when welding the back side.

[0042] The pneumatic clamping unit 150 includes a clamping arm 210, a drive cylinder 200, and a hinge structure 220. The distance A between the center of the hinge structure 220 and the center of the drive cylinder 200, and the distance B between the center of the hinge structure 220 and the center of the workpiece contact area, satisfying the relationship 1.2A ≤ B ≤ 1.5A, to optimize force transmission efficiency. A gas distribution valve 190 is electrically connected to all drive cylinders 200, enabling centralized control of the working state of each pneumatic clamping unit 150.

[0043] During welding, appropriate first and second mounting bases are selected according to the specific specifications and shape of the workpiece to be processed, and fixed to the machine base 120 through a quick-release structure. Since the base is composed of multiple independent mounting plates arranged in a staggered manner, it can be flexibly adjusted to accommodate workpieces of different sizes and shapes. The machine table 160 is leveled using the first fine-tuning module 170 located below the first rotary base 100 and the second fine-tuning module 180 located below the second rotary base 110, ensuring the entire clamping station is horizontal, providing a basis for subsequent precise positioning. The position of the workpiece on the first processing plane 130 or the second processing plane 230 is precisely adjusted using the scale markings along the length of the machine base 120. The gas distribution valve 190 is opened, allowing compressed air to flow to the drive cylinders 200 in each pneumatic clamping unit 150. The drive cylinders 200 push the clamping arms 210, firmly clamping the workpiece through the hinge structure 220. According to the design, the distance A between the center of hinge structure 220 and the center of drive cylinder 200, and the distance B between the center of hinge structure 220 and the center of workpiece contact part satisfy the relationship 1.2A≤B≤1.5A, ensuring optimal force transmission efficiency and stability. If it is necessary to change the welding angle, the entire machine base 120 can be rotated by synchronously driving the first rotating seat 100 and the second rotating seat 110 to adjust to the most suitable angle position.

[0044] The welding robotic arm moves along a guide rail 240 parallel to one side of the base 120 to the designated starting welding point. The design of the guide rail 240 allows the robotic arm to move freely along the length of the base 120 to cover a larger working area. The welding program is started, and the welding robotic arm performs welding operations on the workpiece according to a preset path. During this process, the position and posture of the robotic arm can be adjusted at any time according to actual needs to achieve the best welding effect. If welding of the other side is required during the welding process, the staggered mounting plate design between the first processing plane 130 and the second processing plane 230 allows the welding tool to extend from one processing plane to the other, achieving back-side welding.

[0045] After welding is completed, the gas distribution valve 190 is first closed to cut off the air supply to the drive cylinder 200. As the air pressure is released, the pneumatic clamping unit 150 automatically releases, releasing the workpiece from the clamping station and preparing for the next workpiece. This operating procedure not only improves the overall efficiency and flexibility of the welding production line but also ensures welding quality and safe handling of the workpiece.

[0046] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
