The utility model discloses a kind of earphone circuit mainboard welding jigs, it is related to earphone circuit mainboard technical field, including rack, clamping plate is provided in the upper portion of rack, clamping plate is used to clamp and fix earphone circuit mainboard;Second trapezoidal block is slidably connected in the top of rack, second trapezoidal block is provided with elastic assembly outside, and elastic assembly is provided with abutment plate outside;Horizontal drive mechanism is set to the outside of rack, and horizontal drive mechanism is used to drive second trapezoidal block to move.The utility model utilizes two clamping plate elevating to realize the purpose of clamping and fixing earphone circuit mainboard, while clamping plate moves second trapezoidal block by horizontal drive mechanism in elevating process, second trapezoidal block moves abutment plate by elastic assembly, abutment plate extrudes and horizontally clamps and fixes earphone circuit mainboard side wall, and earphone circuit mainboard is centered and positioned while fixing mainboard, prevent earphone circuit mainboard from the condition of deviation, and abutment plate is applicable to different size mainboard by elastic assembly.

This invention discloses an automatic welding device for the circumferential seam of a hydraulic cylinder with a tilting mechanism, which relates to the field of welding technology. Through the combined action of a burr removal component and multiple contour-following support components, the outer contour of the cylinder section can be simulated and contoured before forming support. This allows the tops of the burr removal component and some of the contour-following support components to form a contour shape that matches the cylinder section, creating a ring-shaped enclosure of the lower part of the cylinder section and providing stable support. When the support components form support for the bottom of the cylinder section, they work with the multiple contour-following support components on both sides to form simulated support for the cylinder section. Furthermore, while supporting the cylinder section, a high-speed rotating grinding wheel can grind the welded circumferential seam, removing metal burrs and weld slag generated during welding, avoiding stress concentration at the tips, and ensuring the connection strength of the weld.

The utility model discloses a kind of aluminium alloy section bar processing equipment, comprising: cutting processing machine cabinet, angle adjusting slide is limit slidably arranged in cutting processing machine cabinet upper one end, clamping rotary frame is rotatably connected in angle adjusting slide upper one end, limit clamping plate is screw-connected and arranged in clamping rotary frame inside one end, and adjusting locking bolt is limit and is penetrated in angle adjusting slide and clamping rotary frame inside;In the utility model, by holding rotary handle, locking internal thread sleeve can be loosened, so that clamping rotary frame can be rotated to quickly adjust the angle of cutting, after adjustment is completed, locking internal thread sleeve is again reversely rotated and tightened, so that it is firmly attached to rotary frame base and is pressed down, so that the adjustment and locking of clamping rotary frame angle can be quickly and conveniently completed.

The utility model discloses a kind of silicone glue subpackaging metering devices, including base, the side of base top end is equipped with shell, and the bottom end of shell is equipped with shell, the side of shell top end is equipped with conduit, and the top end of conduit is equipped with valve, the side of base top end is equipped with support, and the middle position of fixed plate is penetrated by threaded rod.The utility model is equipped with fixed plate by being installed in the top of placing plate, fixed plate and limit plate are connected by threaded rod and guide rod, threaded rod and fixed plate constitute screw thread connection, can seize threaded rod and drive threaded rod to rotate, threaded rod rotation will drive limit plate to move, limit plate moves will be container clamped in middle, limit fixing to container, prevent the situation that container appears to deviate, guide rod penetrates fixed plate, guide rod can prevent the situation that limit plate appears to deviate, to reach the purpose that silicone glue subpackaging metering device is convenient to limit container.

This application provides a tooling fixture for welding the duct of an axial flow fan, including a base with a fixing ring in the middle. The base and the fixing ring are connected by a slide rail, a slider is mounted on the slide rail, and an integrally formed abutment plate is provided on the top end face of the slider. A pressure block is provided on the slider for cooperating with it, and a tooling fixture for clamping the duct body is provided on the top end face of the pressure block. This utility model, by adding multiple tooling fixtures that cooperate with the abutment plate and pressure block, achieves clamping of the duct body from multiple positions, effectively preventing displacement during welding, significantly improving welding quality, and resulting in higher weld consistency.
