3results about How to "Reduce processing technology" patented technology

This application belongs to the field of lighting equipment technology, and provides a lighting device that is convenient for light-sensor installation, including a housing, a lamp panel, a reflector, a light sensor, and a lampshade. The housing has a light-emitting hole; the lamp panel is installed inside the housing; the reflector is installed inside the housing and is used to reflect the light from the lamp panel to the light-emitting hole; the light sensor is installed on the lamp panel; and the lampshade covers the light-emitting hole. This application has a simple and compact structure, low glare, and reduces process steps and processing costs.

This invention discloses a powder metallurgy external helical gear workpiece forming die, comprising a forming base with a forming cavity; a first punch; a second punch with a first forming end and a first connecting end, and a first through-channel within the second punch; a third punch with a second forming end and a second connecting end, and a second through-channel within the third punch; forming helical teeth on the inner surface of the second forming end; at least two clearance through holes on the second connecting end, extending circumferentially along the second connecting end; a fourth punch with a third forming end and a third connecting end; guiding helical teeth on the outer surface of the third forming end, the guiding helical teeth engaging with the forming helical teeth; and a mandrel assembly including a mounting base and at least two mandrels spaced apart axially from the mounting base. This invention can form helical teeth and holes on the helical teeth in a single die-casting operation.

The utility model discloses a kind of plate assembly, gear box and stepping motor. Plate assembly includes upper pole plate and gear plate integrally injection molded in the side of the upper pole plate;Gear plate has fastening part, for fastening the cover plate of assembled gear box. The plate assembly provided by the utility model, which integrally injection molds the upper pole plate and the gear plate together, optimizes the assembly structure, optimizes the radial collision that may be generated in the low-frequency operation process of motor to cause motor abnormal sound;Gear plate is assembled in gear plate, and the noise of separate gear box body model can be tested (i.e. detecting the noise problem of gear box), without gear box noise detection after the completion of the overall assembly of existing motor, optimize product quality detection method, so that its gear box body can independently detect whether its noise meets quality requirement.
