This utility model discloses an alloy plate unloading fixture, relating to the field of fixtures. The utility model includes a unloading machine body, with first motors symmetrically mounted on both sides of the unloading machine body. A commutator is fixedly connected to the output end of each first motor, and a lever is rigidly connected to the commutator. The lever is driven to rotate by the first motors. A photoelectric sensor is installed on one side of the unloading machine body. The photoelectric sensor employs advanced sensing technology. The symmetrically arranged first motors, driven by the commutator, directly contact the alloy plate for physical correction, ensuring the immediacy and accuracy of position adjustment and avoiding the efficiency bottleneck of traditional manual positioning. The photoelectric sensor, combined with a laterally movable protrusion and groove design, enables dynamic adjustment of the monitoring position, adapting to various sizes of plates. The replaceable lever size further expands equipment compatibility, reduces changeover costs, and forms a high-precision, highly flexible positioning system.

This utility model discloses a cutting tool for quickly removing cylinder clamps, including a base, a grooving device, and a round sleeve positioning device. The base integrates the grooving device and the round sleeve positioning device into one unit. The grooving blade is driven by a built-in power and extends into the sleeve body to perform a circumferential equal-depth cut on the cylinder, destroying its entire circumferential binding force in one go, reducing the removal time from several minutes to several seconds. The inner diameter of the sleeve body matches the outer diameter of the cylinder, forming a self-centering positioning. The cutting depth deviation is ≤0.1 mm, completely avoiding the internal bushing and eliminating the risks of chiseling damage, deformation, and splashing caused by traditional hammering. The transparent protective sleeve can be quickly installed and removed, and the cutting status can be observed in real time. The positioning device is connected to the base by fixing bolts, which facilitates the replacement of different specifications of sleeves, realizing multi-purpose use. This utility model is small in size, lightweight, and requires no external hydraulic or electrical control. It can utilize the power of existing grooving equipment on-site to achieve efficient, labor-saving, zero-damage, and highly consistent rapid removal, significantly improving production efficiency and operational safety.

The device includes bracketless invisible corrector, connecting groove body and connecting head, and the front part of bracketless invisible corrector is provided with connecting groove body, and bracketless invisible corrector and connecting groove body are integrally made, and connecting head is connected with bracketless invisible corrector by cooperation with connecting groove body, and connecting groove body and connecting head are all provided with arc part that is in accord with the front side of bracketless invisible corrector, and the arc part between connecting groove body and connecting head is connected through ball head structure. The device can conveniently and stably install components to upper dentition or lower dentition, and can extend to outside of oral cavity through connecting head, and does not need glue and tooth abrasion, and is a non-invasive, convenient and painless connecting device.

This invention discloses a laser cutting machine for precision workpiece machining, capable of automatically positioning the workpiece. It relates to the field of precision workpiece machining technology and includes a worktable and a positioning assembly. A support roller is rotatably connected to the center of the worktable, and a waste bin is located below the worktable. A three-axis slide module is installed at the rear of the worktable, and the output end of the three-axis slide module is connected to a laser cutting head. During positioning, the drive motor first drives the two slide blocks to move synchronously towards each other via positive and negative threaded screws. A buffer spring pushes the roller frame and its rollers to contact the workpiece. The buffer spring, with its low elastic coefficient, ensures a gentle contact force. After initial positioning, the slide blocks continue to move, compressing the buffer spring. The drive slotted plate, through rollers, drives the positioning seat and positioning plate to complete the final rigid clamping. This process of first guiding and then locking can complete high-precision automatic centering within seconds, resulting in high positioning accuracy.

The utility model provides a kind of zero plugging three claw spring piece, including main component, the main component includes adapter PCB insertion section, U-shaped positioning section, intermediate clamp jaw, side clamp jaw, clamping part and welding portion;The front surface bottom of the U-shaped positioning section is provided with adapter PCB insertion section, and the rear surface bottom of the U-shaped positioning section is provided with intermediate clamp jaw.The utility model is realized by adopting the elastic deformation of side clamp jaw and intermediate clamp jaw that pin is automatically in position, without traditional plugging action, while clamping part end is provided with smooth inverted triangular structure, eliminates sharp contact point, ensures that chip pin zero damage in testing process;Through two side clamping parts and intermediate arc-shaped clamping block form stable triangular area, utilize the resilience of elastic clamp jaw to evenly compress pin, contact resistance fluctuation is less than 5mΩ, can stably bear more than 10A large current test, cooperate U-shaped positioning section and the double limiting structure of symmetrical barb, avoid spring piece displacement, guarantee the stability and accuracy of signal transmission.

The invention belongs to the technical field of aviation equipment maintenance, and particularly relates to a cleaning agent suitable for an aircraft brake pad and a preparation method of the cleaning agent. The cleaning agent provided by the invention comprises a continuous-phase gel matrix and two-phase microcapsules dispersed in the continuous-phase gel matrix, the continuous phase gel matrix comprises the following components in percentage by weight: a main solvent, a penetrant, a chelating agent, a gelling agent, a corrosion inhibitor and the balance of deionized water; a shell layer of the biphase microcapsule is a mechanical force responsive polymer shell, and an inner core of the biphase microcapsule is a penetration softening agent and a volatile stripping agent which are not mutually dissolved. Through a unique'gel matrix + two-phase microcapsule 'synergistic system, oil stains can be quickly permeated and dissolved, carbonized particles and metal oxides can be disintegrated, and cleaning is thorough. The two-phase microcapsules realize stepped removal of stubborn carbonized dirt, namely permeation softening and pneumatic stripping, so that the cleaning efficiency is greatly improved, and the physical wear of a matrix is reduced.
