Centerless grinding automatic feeding device for extruding PCB drill points

Abstract

The invention discloses a centerless grinding automatic feeding device for extruding PCB drill points, and relates to the technical field of feeding devices. The centerless grinding automatic feeding device comprises a linear vibration feeding mechanism connected with a centerless grinding machine through a main body connection protection mechanism and an electrical control mechanism, and the linear vibration feeding mechanism receives bars which come from a storage hopper mechanism and are sorted through a pushing sorting mechanism and feeds the sorted bars into the centerless grinding machine one by one for processing; and the electrical control mechanism is mounted at the bottom of the main body connection protection mechanism and is used for controlling the linear vibration feeding mechanism to count the bars and controlling the operation of the pushing sorting mechanism. The device can be compactly connected with existing equipment, and the installation space is reduced; and rapid, continuous and automatic machining of external circles of extrusion PCB drill point type hard alloy products, rapid switching of machining of external circles of multiple kinds of products and machining quality control of the external circles of the products can be achieved.

Description

technical field [0001] The invention relates to an automatic feeding device for extruding PCB drill pins for centerless grinding, and belongs to the technical field of feeding devices. Background technique [0002] At present, there are many varieties of extruded PCB drill needles on the market, and the efficiency of small batches of small workpiece products is low. They can only be processed by manual feeding. . Therefore, it is necessary to design a device that can automatically and continuously feed materials and quickly switch varieties based on the traditional method of manually feeding and processing extruded PCB drills. [0003] At present, the automatic feeding and receiving machines for hard alloys on the market can continuously perform large-scale operations, but they cannot automatically feed the extruded PCB drill series, that is, small-diameter slender bars, and some feeding and receiving devices It takes a long time to switch varieties; for products with many...
