Automatic press-polishing machine for gold bracelet

Abstract

The invention discloses an automatic press-polishing machine for a gold bracelet, and belongs to the field of automatic jewelry machining devices. The automatic press-polishing machine is composed of a base, a guide rail, lateral supporting plates, a swinging shifting fork, a first direct-current motor, a bracelet supporting body, a press-polishing needle, swinging pieces, a lead screw stepping motor, middle clamps, a second direct-current motor, a flywheel, a transmission shifting shaft and the like. The guide rail, the lateral supporting plates, the first direct-current motor, the lead screw stepping motor and vertical plates are installed on the upper portion of the base, the swinging shifting fork is installed on a sliding block, the upper portion of the swinging shifting fork is connected with the bracelet supporting body through the transmission shifting shaft, and the press-polishing needle is fixed to the swinging pieces through the middle clamps. The up-and-down positions of the middle clamps in the swinging pieces are adjusted to enable the press-polishing needle to be in contact with the bracelet, and the second direct-current motor drives the swinging pieces to perform swinging movement through the flywheel. Front-and-back movement is converted into arc-shaped movement of the bracelet through a swinging shifting-fork structure, front-and-back swinging of the bracelet is achieved, and the cambered surface of the bracelet is completely machined; the bracelet supporting body is of a handle cam structure, the bracelet can be effectively prevented from loosening, and the bracelet can be assembled and disassembled in real time.

Description

technical field [0001] The invention relates to an automatic calendering machine for gold bracelets. Specifically, two DC motors and a stepping motor are used as actuators to drive the movement of the bracelet and the calendering needle, so as to realize the automatic calendering of the surface of the bracelet. An automatic equipment belongs to the field of jewelry automatic processing equipment. Background technique [0002] The production of gold bracelets mainly adopts the production methods of mold casting and surface calendering. Surface calendering is a process in which knives such as diamond knives and amber knives are used to rub back and forth on the surface of the bracelet to make the surface of the gold bracelet shiny. At present, the process is mainly completed manually, which is labor-intensive and the consistency of the finished product is poor. There is an urgent need for an automated device to complete this process, but there is currently no such device. ...
