[0020] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0021] The present invention provides a stainless steel plate splicing and positioning device. Figure 1-4 As shown, the stainless steel plate splicing and positioning device includes: a base box 1, an assembly frame 2 is fixedly installed on the top of the base box 1, and a placement plate 3 is fixedly installed on the assembly frame 2 for placing the stainless steel plate body 7 to be welded; a positioning plate 4, the positioning plate 4 is arranged on the base box 1 and the distance between the positioning plate 3 and the positioning plate 3 is adjustable, and is used to clamp the stainless steel plate body 7 to be welded; a plurality of mounting frames 5, a plurality of the mounting frames 5 are respectively fixedly installed on the top of the placement plate 3 and the positioning plate 4, and the mounting frames 5 are all rotatably installed with guide wheels 6 for carrying the stainless steel plate body 7 to be welded; an adjustment mechanism, the adjustment mechanism is arranged on the base box 1, and is used to regulate the movement of the positioning plate 4.

[0022] In this embodiment, the stainless steel plate body 7 to be welded is placed on the placement plate 3. The base box 1 serves as the basic support structure of the entire device, providing a stable installation platform for the assembly rack 2 above. The assembly rack 2 acts as a bridge connecting the base box 1 and the placement plate 3, so that the placement plate 3 can be firmly positioned at an appropriate working height. This stable structural design provides a solid foundation for the positioning of the stainless steel plate and subsequent welding operations, avoiding the displacement of the steel plate position due to foundation shaking during operation, thereby ensuring the stability and accuracy of the welding process. The placement plate 3 provides a flat placement surface for the stainless steel plate body 7, which helps to preliminarily determine the placement posture of the steel plate and facilitates subsequent precise positioning with the positioning plate 4. The spacing between the positioning plate 4 and the placement plate 3 is adjusted by the adjustment mechanism, so that the positioning plate 4 moves closer to the placement plate 3 until the two stainless steel plate bodies 7 to be welded are clamped and positioned. Unlike traditional methods that rely on manual support or simple clamps, the positioning plate 4 can accurately adjust the spacing with the placement plate 3 according to the actual thickness and size requirements of the stainless steel plate, thereby stably and accurately fixing the stainless steel plate body 7. This design effectively prevents the movement and dislocation of the steel plate during the welding process, greatly reduces the occurrence of problems such as weak welds and cold welds, ensures the quality and stability of the welds, improves the strength and fatigue life of the welded structure, and helps to obtain welded products with better appearance quality, especially meeting the production needs of stainless steel products with high decorative requirements; multiple mounting brackets 5 are installed on the top of the placement plate 3 and the positioning plate 4, and the guide wheel 6 is rotatably installed on the mounting bracket 5. When the stainless steel plate body 7 is placed on the placement plate 3 and clamped by the positioning plate 4, the bottom surface of the steel plate contacts the guide wheel 6 and can be slid on the guide wheel 6 to adjust its position; the guide wheel 6 provides a low-friction bearing surface for the placement and adjustment of the stainless steel plate body 7, making it easier and more convenient to place the stainless steel plate in the appropriate position and to make fine adjustments before welding, and also facilitates the subsequent pushing and removal of the steel plate after the weld is spliced. The movement of the positioning plate 4 is precisely regulated by the adjustment mechanism to achieve translation and change the distance between it and the placement plate 3.

[0023] In a further preferred embodiment of the present utility model, the adjusting mechanism includes: a screw 8 rotatably installed in the base box 1, an assembly plate 9 is threadedly sleeved on the screw 8, the top of the assembly plate 9 passes through the base box 1 and is fixedly connected to the positioning plate 4; a guide rod 10 fixed in the base box 1, the guide rod 10 passes through the assembly plate 9 and is used for limiting guidance; a motor 11 fixed in the base box 1, the output shaft of the motor 11 is fixedly connected to the screw 8 through a coupling, and is used to drive the screw 8 to rotate.

[0024] In this embodiment, when the motor 11 drives the screw 8 to rotate, since the assembly plate 9 is threadedly sleeved on the screw 8 and the top end of the assembly plate 9 is fixedly connected to the positioning plate 4, the rotational motion of the screw 8 will be converted into a linear translational motion of the assembly plate 9 and the positioning plate 4; this threaded transmission structure can accurately convert the rotational power of the motor 11 into a linear displacement of the positioning plate 4, thereby realizing high-precision control of the position of the positioning plate 4. Compared with some transmission methods relying on hydraulic or pneumatic pressure, threaded transmission has higher positioning accuracy and stability, and can effectively avoid positioning errors caused by transmission medium leakage or pressure fluctuations, ensuring that each adjustment of the spacing between the positioning plate 4 and the placement plate 3 can accurately meet the positioning requirements of different stainless steel plate bodies 7, thereby providing reliable guarantees for high-quality welding operations and improving the qualification rate and consistency of welding products; in the process of the assembly plate 9 moving with the rotation of the screw 8, the guide rod 10 passes through the assembly plate 9, limiting the assembly plate 9 to only linear motion along the axial direction of the guide rod 10; the guide rod 10 plays a key limiting and guiding role, preventing the assembly plate 9 from rotating or offsetting when the screw 8 rotates, ensuring that the positioning plate 4 always maintains smooth linear movement. This not only further improves the accuracy and stability of the movement of the positioning plate 4, avoids the positioning effect of the stainless steel plate body 7 being affected by the shaking of the positioning plate 4, but also effectively protects the threaded connection structure between the screw 8 and the assembly plate 9, reduces thread wear caused by lateral force, extends the service life of the adjustment mechanism, reduces equipment maintenance costs, and ensures that the entire stainless steel plate splicing and positioning device operates stably under long-term, high-intensity working conditions, and continuously provides accurate positioning services; the motor 11 serves as a power source, and its output shaft is fixedly connected to the screw 8 through a coupling, and starts and drives the screw 8 to rotate after receiving an external control signal; the motor 11 can provide stable, continuous and precisely controllable power output. Compared with manually operating the positioning plate 4, the motor drive greatly improves the adjustment speed and efficiency, and reduces the time and labor intensity of manual operation. In the scenario of large-scale production of stainless steel welding components, it can significantly improve production efficiency and meet the needs of a fast production rhythm. At the same time, the precise control characteristics of the motor 11 enable it to accurately adjust the rotation angle and speed of the screw 8 according to the preset program or the operator's instructions, thereby achieving precise adjustment of the position of the positioning plate 4, further improving the accuracy and reliability of the stainless steel plate splicing positioning, helping to obtain higher quality welding products and enhance the company's competitiveness in the market.

[0025] In a further preferred embodiment of the present invention, an electric hydraulic rod 12 is vertically fixedly installed on one side of the assembly frame 2 and the positioning plate 4 for regulating the lifting and lowering. A connecting frame 13 is fixedly installed on the output rod of the electric hydraulic rod 12, and a fixing frame 14 is fixed on the connecting frame 13. A pressure wheel 15 is rotatably installed on the fixing frame 14 for pressing the stainless steel plate body 7.

[0026] In this embodiment, after the stainless steel plate body 7 is placed on the placement plate 3 and initially positioned, the electric hydraulic rod 12 is activated, and its output rod performs telescopic movement according to a set program or manual instruction, thereby driving the connecting frame 13, the fixing frame 14, and the pressure roller 15 to move upward and downward as a whole; the electric hydraulic rod 12 can provide a large driving force, ensuring that the pressure roller 15 can stably press the stainless steel plate body 7. Compared with relying solely on the clamping force of the positioning plate 4 and the placement plate 3, the pressure roller 15 applies additional pressure from above under the action of the electric hydraulic rod 12, further enhancing the stability of the stainless steel plate during the welding process, effectively preventing the steel plate from being displaced or deformed due to factors such as stress changes and vibration during the welding process, greatly reducing the probability of quality problems such as substandard welds and cold welds, and improving the strength and reliability of the welded structure. At the same time, the lifting and lowering action of the electric hydraulic rod 12 can be adjusted by a precise electronic control system, which can adapt to stainless steel plate bodies 7 of different thicknesses and shapes, provide just the right pressing force, avoid damage to the steel plate due to excessive pressing or positioning failure due to insufficient pressing force, and further improve the adaptability and flexibility of the device to various stainless steel plate welding operations; the connecting frame 13 firmly connects the output rod of the electric hydraulic rod 12 with the fixed frame 14, and the fixed frame 14 provides an installation base for the pressure wheel 15, which contacts and rolls the surface of the stainless steel plate body 7 under the drive of the electric hydraulic rod 12; the pressure wheel 15 adopts a rotating installation method. In the process of pressing the stainless steel plate body 7, when the steel plate needs to make a slight position adjustment, the pressure wheel 15 can roll on the surface of the steel plate, reducing the friction between the steel plate and the steel plate, avoiding scratching the steel plate surface due to forced fixation, and protecting the appearance quality of the stainless steel plate. In addition, the structural design of the connecting frame 13 and the fixing frame 14 makes the entire pressing system compact and stable, and can reliably transmit the driving force of the electric hydraulic rod 12, ensuring that the pressing wheel 15 always applies pressure to the stainless steel plate body 7 in the correct position and direction, further enhancing the reliability and stability of the device during the splicing and positioning process of the stainless steel plates.

[0027] In a further preferred embodiment of the present invention, a strip-shaped through-slot 16 is provided on the top of the base box 1 , and the width of the strip-shaped through-slot 16 is greater than that of the assembly plate 9 .

[0028] In this embodiment, when the assembly plate 9 moves linearly under the rotation drive of the screw 8, its top end is fixedly connected to the positioning plate 4, and the main part of the assembly plate 9 moves inside the base box 1. At this time, the strip through groove 16 provides the necessary spatial channel for the movement of the assembly plate 9. Its width is greater than the assembly plate 9, so that the assembly plate 9 can be smoothly translated within the limited range of the top of the base box 1; the strip through groove 16 effectively avoids the top structure of the base box 1 from hindering the movement of the assembly plate 9, and ensures that the positioning plate 4 can smoothly and smoothly adjust the distance with the placement plate 3 under the action of the adjustment mechanism, thereby realizing the precise positioning of the stainless steel plate body 7.

[0029] In a further preferred embodiment of the present invention, balls are embedded in the bottom of the assembly plate 9 , and the balls are in contact with the bottom inner wall of the base box 1 .

[0030] In this embodiment, as assembly plate 9 moves within base box 1 as screw 8 rotates, balls embedded in the bottom of assembly plate 9 contact and roll against the bottom inner wall of base box 1. The presence of the balls converts sliding friction between assembly plate 9 and the bottom inner wall of base box 1 into rolling friction. The coefficient of rolling friction is much smaller than the coefficient of sliding friction, significantly reducing the friction experienced by assembly plate 9 during movement.

[0031] In a further preferred embodiment of the present invention, a detachable inspection panel is provided on the base box 1, and the inspection panel is threadedly connected to the base box 1 via screws.

[0032] In this embodiment, when it is necessary to inspect, repair, maintain, or troubleshoot components within the base box 1, such as the screw 8, guide rod 10, motor 11, and other adjustment mechanism components, as well as any other transmission or electrical circuits, the access panel can be removed from the base box 1 by unscrewing the screws. This detachable design greatly facilitates equipment maintenance. During daily use, if a component malfunctions or requires regular maintenance, maintenance personnel can quickly and easily open the base box 1 and directly access the various internal components without the need for complex disassembly of the entire device or damage to the overall structure.

[0033] In a further preferred embodiment of the present invention, a plurality of support columns are symmetrically fixedly installed on the bottom of the base box 1, and anti-slip pads are fixedly installed on the bottom ends of the support columns.

[0034] In this embodiment, multiple support columns are symmetrically installed from the bottom of the base box 1, and the anti-slip pads at the bottom are in contact with the placement plane (such as the workshop floor), jointly bearing the weight of the entire stainless steel plate splicing and positioning device and keeping the device stable.

[0035] In summary, a stable basic structure is constructed by the base box 1, the assembly frame 2 and the placement plate 3, which lays a solid foundation for positioning and welding operations, prevents the steel plate position from being offset due to foundation shaking, ensures a stable and accurate process, and provides a flat surface for the placement of the steel plate to assist in preliminary positioning; the positioning plate 4 accurately adjusts the spacing according to the characteristics of the stainless steel plate, effectively prevents the movement and dislocation of the steel plate during welding, reduces weld defects, improves welding quality, structural strength and fatigue life, and meets the needs of decorative products; the mounting frame 5 and the guide wheel 6 provide low-friction load-bearing and fine-tuning convenience, which is convenient for placing, adjusting and pushing out the steel plate, and optimizes the convenience of operation; the screw 8, the assembly plate 9, the guide rod 10 and the motor 11 in the adjustment mechanism use the high-precision stability of the threaded transmission, combined with the limit guide of the guide rod, and the stable, continuous and precisely controllable power output of the motor to achieve precise control of the position of the positioning plate 4, improving the adjustment Reduce speed and efficiency, reduce the burden of manual operation, adapt to large-scale production, ensure product qualification rate and consistency, improve positioning accuracy and reliability, and enhance corporate competitiveness; the electric hydraulic rod 12, connecting frame 13, fixing frame 14 and pressure wheel 15 use the powerful driving force and precise electronic control adjustment of the electric hydraulic rod to press the stainless steel plate through the pressure wheel rolling, thereby enhancing stability, protecting the appearance of the steel plate, and assisting in precise calibration; the strip groove 16 opens up a smooth channel for the movement of the assembly plate 9, avoiding structural obstructions, ensuring the precise displacement of the positioning plate 4 and the normal operation of the device; the ball bearings at the bottom of the assembly plate 9 convert sliding friction into rolling friction, reducing motor load and energy consumption, making the assembly plate 9 move more smoothly, and improving positioning accuracy and efficiency; the detachable inspection panel on the base box 1 is detachable in design, which facilitates the maintenance of internal components, shortens maintenance time, reduces downtime, and reduces maintenance difficulty and cost.
