Convenient-for-die-replacement punching mechanism for recessed holes of digital-camera baseplates

Abstract

The invention discloses a convenient-for-die-replacement punching mechanism for recessed holes of digital-camera baseplates. The convenient-for-die-replacement punching mechanism comprises a frame. Anupper support frame is fixed to the top face of a top plate of the frame. A top plate of the upper support frame is located right above a bottom fixing block. Lifting motors are fixed to two sides ofthe top face of the top plate of the upper support plate. Rotating shafts of the lifting motors penetrate the top plate of the upper support frame, and are in screw joint with lifting thread sleeves.The bottom ends of the lifting thread sleeves are fixed to the top face of an upper press block. The upper press block is pressed to the top face of a to-be-processed plate. A screw-joint through hole is formed in the middle of the upper press block. An upper die is connected into the screw-joint through hole in a screwed mode. The bottom face of the upper die is pressed onto the top face of theto-be-processed plate. The convenient-for-die-replacement punching mechanism has the advantages that a common steel plate can serve as the to-be-processed plate to be punched, and the bottom face of the middle of the to-be-processed plate is raised upwardly to form a recessed hole; rapid processing, weight reduction and good effect are realized; the upper die and a forming block are detachable components, and the punching mechanism is convenient to replace and maintain.

Description

Technical field: [0001] The invention relates to the technical field of digital camera processing equipment, in particular to a punching mechanism for concave holes on a bottom plate of a digital camera with convenient mold replacement. Background technique: [0002] The bottom plate of the existing digital camera is generally provided with a processing concave hole, and threads are set in the processing concave hole, so as to facilitate the connection of the camera bracket. The raised part is then drilled on the bottom of the bottom of the base plate to drill holes for the raised part, and the cast base plate is thicker and heavier, which greatly increases the weight of the entire camera, which is inconvenient to carry and high in cost; there are still The ordinary thin steel plate is used for processing, generally, the bottom surface of the steel plate is punched, and then the screw sleeve is installed on the top surface of the steel plate, and the screw sleeve communicate...

[0002] The bottom plate of the existing digital camera is generally provided with a processing concave hole, and threads are set in the processing concave hole, so as to facilitate the connection of the camera bracket. The raised part is then drilled on the bottom of the bottom of the base plate to drill holes for the raised part, and the cast base plate is thicker and heavier, which greatly increases the weight of the entire camera, which is inconvenient to carry and high in cost; there are still The ordinary thin steel plate is used for processing, generally, the bottom surface of the steel plate is punched, and then the screw sleeve is installed on the top surface of the steel plate, and the screw sleeve communicates with the through hole of the thin steel plate, which is troublesome to manufacture and low in efficiency, so it can be The steel plate is stamped to form concave holes for processing, but there is no such processing equipment at present
