This invention provides an automatic copper busbar welding device for busbar trunking production, relating to the field of busbar trunking welding. The automatic copper busbar welding device for busbar trunking production includes two docking components. Each docking component includes a YZ axis assembly, a flipping assembly, a clamping platform, a drive assembly, a fixing assembly, and a preheating assembly. The flipping assembly is mounted on the YZ axis assembly and can automatically move along the Y and Z axes based on the YZ axis assembly. The clamping platform is mounted on the flipping assembly and can switch between horizontal and vertical 90-degree angles. The drive assembly, fixing assembly, and preheating assembly are all mounted on the clamping platform. This automatic copper busbar welding device for busbar trunking production, by setting up the drive assembly and fixing assembly, can clamp copper busbars specifically for busbar trunking. Even with thin copper busbars, drive transmission can be achieved. It is applicable to both long and short copper busbars. The fixing assembly can clamp the copper busbars, facilitating precise welding later.

It includes a hollow cylindrical shell with several lifting lugs on its exterior. Two through holes are formed through the middle of the side wall of the hollow cylindrical shell. A chuck is installed inside each through hole, and a removable plug is installed outside. A spring is installed between the chuck and the removable plug. This utility model allows for convenient and quick transfer of remelted billets, reducing manual labor intensity and improving operational safety and efficiency.

The application discloses a low-cost soft mold manufacturing method applicable to a T-shaped rib reinforced skin structure, and comprises the following steps: adopting an isolation film and a vacuum bag to integrally encapsulate a laminated plate skin blank body, a T-shaped rib blank body and a T-shaped soft mold on a forming tool; adopting a hot press tank to perform co-curing forming of a "wet" state laminated plate skin and a "wet" state T-shaped rib according to the curing requirements allowed by the material specification of carbon fiber prepreg, and obtaining the T-shaped rib reinforced skin structure; the application has the beneficial effects that: through the structure splitting of step S1, the customization of special tooling (a forming tool, a T-shaped rib pre-compaction tool and a soft mold forming tool), the accurate positioning and cooperation of step S4 and the co-curing forming of the "wet" state laminated plate skin and the "wet" state T-shaped rib of step S6, the defects of poor adaptability of the T-shaped rib to the skin, easy interference of R angles, easy wrinkling of edges and the need of post-grinding in the traditional gluing process are effectively solved.

This invention relates to the field of monochromator design technology, specifically providing a micro-motion slit assembly and monochromator for use in a monochromator. The slit plates of the micro-motion slit assembly are connected to a slit mounting plate and slidably connected to a slit base via a guide rail. A micrometer screw converts rotation into linear motion of a gap cone, and the gap cone adjusts the width of the slit between the two slit plates. The micrometer screw and gap cone enable large-range, high-precision adjustment of the slit width. This micro-motion slit assembly serves as both the output and input slit assemblies of the monochromator, and a vacuum transmission environment is provided by the housing. Spectral scanning or fixed-point wavelength output is achieved by rotating the beam splitter. This invention achieves continuous coverage of the entire 100-435nm wavelength band through vacuum design and improves the resolution adjustment accuracy of the monochromator's output light through the micro-motion slit design.

This utility model relates to the field of agricultural machinery technology, specifically a pneumatic suction furrowing precision seeder, comprising a frame, with a furrowing roller rotatably connected between the front ends of the left and right inner walls of the frame. Furrowing teeth are integrally arranged evenly along the circumferential direction on the outer side of the furrowing roller. A connecting rod is provided between the middle of the left and right inner walls of the frame. The advantages are: This pneumatic suction furrowing precision seeder uses a fan to drive the seeding roller for pneumatic suction and material loading. A motor drives the furrowing roller, rotating shaft, and furrowing teeth to rotate and move, simultaneously driving the seeding roller to rotate and load material. Seeds are then placed through a seed tube. Finally, soil is covered to complete the operation. Compared with manual sowing, it saves time and labor, greatly improves efficiency, and can effectively control the sowing quantity and row spacing accuracy, avoiding the waste of seeds during manual sowing. It can also ensure furrowing row spacing and avoid wasting land resources.

The utility model discloses a height adjusting device for an inner wall plate of a forklift box body, which comprises a support frame, an adjusting component is fixedly arranged on the support frame, the adjusting component comprises an operation table and an upper connecting plate which are fixedly connected with the support frame, a transverse moving assembly is horizontally and movably connected on the operation table, and the upper connecting plate is fixedly connected with the transverse moving assembly. A supporting block is vertically and movably connected to the upper connecting plate, and the bottom end face of the supporting block and the top end face of the transverse moving assembly are inclined faces matched with each other and abut against each other. The transverse moving assembly is connected with a driving device to drive the transverse moving assembly to horizontally move on the operation table, and then the supporting block is driven to vertically move on the upper connecting plate. Through the design that the supporting block is attached to the inclined face of the transverse moving assembly, it is guaranteed that the supporting block can move up and down in the transverse moving process of the transverse moving assembly. Therefore, when the forklift box body is assembled, the rear end of the inner wall plate falls on the supporting block, the transverse moving assembly is driven to drive the supporting block to move up and down, and finally the height of the rear end of the inner wall plate is driven to be adjusted, so that the forklift box body is convenient to assemble.
