Method and device for detecting core thickness of drilling bit

Abstract

The invention relates to a detecting method and a device for the thickness of a core bit. An image detecting system is arranged above a bit table provided with the bit to be detected; the bit to be detected arranged on the bit table is driven to rotate by a drive device so as to change the crossing angle between the axes of the bit and the plain shaft of an image; simultaneously the bit to be detected is led to advance and retreat along the axes of the bit and rotate along the axes, then a camera in the image detecting system carries out scanning shooting on any point on the axes of the bit and feeds a signal obtained by detecting the image detecting system into a control system to carry out analysis calculation, thereby obtaining the thickness of the core of any position on the axes direction of the bit. The invention adopts a non-contact measuring method to detect, has a high detecting precision and a fast speed, is flexible to set the parameters as well as is easily and conveniently operated; the detected data can be accounted and analyzed by a computer, thus being very convenient.

Description

technical field [0001] The invention belongs to the field of drill bit detection, in particular to a detection device for non-contact detection of the core thickness of the two grooves of the drill bit using image technology. Background technique [0002] In the field of machining, with the rapid development of the drill bit industry, especially the micro-drill industry, drill bit manufacturers have higher and higher requirements for the quality of drill bits, and the precision of drill bits directly affects the quality of drilled products. In the detection of micro-drilling, the traditional method is to use a microscope to measure the core thickness by destructively grinding off the cross-section of the finished drill bit, or use a contact method to detect the core thickness of the micro-drilling method. This measurement method exists. The shortcomings of high strength, low efficiency, poor stability and easy damage to the product, especially when the diameter of the detect...
