Automatic feeding device for processing step drill

Abstract

The invention discloses an automatic feeding device for processing a step drill. The automatic feeding device comprises a working table, a PLC (Programmable Logic Controller), a support shaft, a rotating mechanism, a limiting mechanism and a thrusting mechanism, wherein the rotating mechanism is used for rotating a raw material rod; the limiting mechanism comprises an upper limiting mechanism anda lower limiting mechanism; the upper limiting mechanism comprises an upper limiting mechanism and a lower limiting mechanism; the lower limiting mechanism comprises a lifting motor, a lifting rod anda second limiting block. The raw material rod is limited by the first limiting block and the second limiting block, and then the raw material rod can be prevented from sliding off when being rotated;the thrusting mechanism comprises a sliding sleeve, a linear lifting motor, a grasping motor and grasping claws; the raw material rod is tightly grasped by the grasping claws and is moved through thethrusting sliding sleeve, and then a good moving effect can be achieved; an infrared sensor is arranged at the tail end of the right side of the working table; when being moved right above the infrared sensor, the raw material rod can be sensed in time, a feeding distance can be calculated, and the processing precision can be improved; by adopting the automatic feeding device, the raw material rod can be intelligently conveyed into a processing device, and time and labor can be saved.

Description

technical field [0001] The invention relates to the technical field of feeding devices, in particular to an automatic feeding device for step drilling. Background technique [0002] Step drill, also known as step drill or pagoda drill, is mainly used for drilling thin steel plates within 3mm. One drill bit can replace multiple drill bits. Holes with different diameters can be processed according to needs, and large holes can be processed at one time. There is no need to replace drill bits and make positioning holes, etc. Some of the existing step drilling processing equipment uses manual loading and unloading, which is time-consuming and laborious, and is prone to errors. If there is an error, there will be more feed or less feed, so that there will be a large error in the processed step drill, and it is easier to waste raw materials. Contents of the invention [0003] The purpose of the present invention is to provide an automatic feeding device for step drilling, which ...
