3results about How to "Simple clamping process" patented technology

The application provides a copper bar positioning and welding clamp, which comprises a pressing assembly, a feeding assembly and a lifting mechanism, wherein the pressing assembly comprises a pressing plate and the lifting mechanism which is used for lifting the pressing plate up and down; the feeding assembly comprises a profiling plate, a plurality of clamping mechanisms and a longitudinal horizontal moving mechanism, the plurality of clamping mechanisms are connected with the moving end of the longitudinal horizontal moving mechanism through a mounting plate; a plurality of profiling portions are arranged at the right end of the profiling plate; each profiling portion is provided with at least one clamping mechanism corresponding to clamping another part of the copper bar, each clamping mechanism comprises an inner top unit and an outer top unit; the inner top unit is arranged on the profiling plate, and the outer top unit is arranged on the side of the profiling portion which is away from the inner top unit; at least one copper nozzle structure is arranged above each clamping mechanism, and the copper nozzle structure is embedded in the pressing plate and penetrates through the pressing plate. The application can ensure that the combined copper bar is positioned accurately and clamped reliably during welding, and can avoid problems such as welding displacement and interlayer gap, can realize quick replacement of the clamp for various products, and can simultaneously weld multiple products at a time.

The application relates to the technical field of high-refractive wafer cutting assisting for optical waveguides, in particular to a cutting assisting tool for high-refractive wafers of optical waveguides, which comprises an operation platform, an electric control overturning extrusion frame movably assembled on the operation platform, an electric control translation type clamping seat movably assembled on the side wall of the electric control overturning extrusion frame, and a pressure self-adapting lifting module arranged on the clamping surface of the electric control translation type clamping seat. The cutting assisting tool for high-refractive wafers of optical waveguides realizes the adaptation of the tool to high-refractive wafers of optical waveguides with different sizes and specifications through a double regulation mode, without the need of replacing special clamps, so that the machining cost is reduced.

The application discloses a blade positioning reference casting mold which is used for preparing a positioning reference on the periphery of a blade of an aero-engine, and comprises a lower mold, a positioning mechanism, an upper mold and a quick-release mechanism. The lower mold is provided with a clamping position for mounting the blade. The positioning mechanism comprises two positioning blocks which are slidably arranged in the lower mold and are used for abutting against opposite sides of the blade. One side of the positioning block which faces the blade is provided with a cavity for forming the positioning reference. The upper mold is used for covering the lower mold and pressing the blade into the clamping position. The quick-release mechanism is connected with the upper mold and the lower mold and is used for locking and fixing the upper mold relative to the lower mold. The blade positioning reference casting mold can form a positioning reference which is convenient to clamp and position on the periphery of the blade. The blade is clamped and positioned by using the positioning reference, so that the clamping process is simplified, and the clamping efficiency and clamping precision are improved.
