Lifting motion and rotation device of diamond grinding intelligent robot

Abstract

The invention discloses a lifting motion and rotation device of a diamond grinding intelligent robot. The lifting motion and rotation device is characterized by comprising a lifting motion and rotation mechanism and a controller which is connected with the lifting motion and rotation mechanism and controls the lifting motion and rotation mechanism to act; the lifting motion and rotation mechanism comprises a stepping motor, a connection motor gear, an internal thread gear, a lifting lead screw core shaft, a lifting and rotating guide column, a guide sleeve stand column and a guide sleeve; the lifting lead screw core shaft is in meshed transmission with the connection motor gear through the internal thread gear, and the lifting and rotating guide column is arranged outside the lifting lead screw core shaft in a sleeving manner; the guide sleeve stand column is vertically arranged on a base, the lifting and rotating guide column and the lifting lead screw core shaft are inserted into a middle hole of the guide sleeve, a rolling ball sleeve is arranged between the lifting and rotating guide column and the guide sleeve, and a positioning groove is formed in the lower portion of the lifting lead screw core shaft in the axial direction; and a lifting lead screw core column limiting pin corresponding to the positioning groove is arranged on the side portion of the lifting and rotating guide column and used for limiting the stroke of up-and-down movement of the lifting lead screw core column. The lifting motion and rotation device is simple in structure and flexible and convenient to use.

Description

technical field [0001] The invention relates to the technical field of diamond processing equipment, and more particularly relates to a lifting motion and rotation device of a diamond grinding intelligent robot. Background technique [0002] Diamonds processed into jewelry are called diamonds. There are various defects on the crystal surface of natural diamond crystals, and there are bubbles, cracks, gaps and other defects inside the crystal. The rough diamonds used to be processed into jewelry can only be processed through the process of decomposition scheme design, decomposition (splitting, sawing or laser cutting), car drilling (edging line), rough grinding (cone grinding), grinding and polishing of table top and petal surface, etc. Become a finished diamond - a jewelry diamond. [0003] Grinding (grinding and polishing) is the most complicated and critical process in diamond processing. In order to maximize the optical properties of diamonds, modern diamond cuts are d...

Problems solved by technology

[0006] The main factors affecting the grinding strength are as follows: 1. The higher the speed of the grinding disc, the greater the grinding strength of the diamond; 2. The increase in the unit pressure will increase the grinding amount of the diamond, but the If the unit pressure is too high, the diamond micropowder will be scraped off quickly, and the wear of the grinding disc will be accelerated, and even the diamond will be broken; 3. The size of the diamond micropowder coating on the working surface of the grinding disc will increase the grinding strength, but the smoothness will change. Poor, the micropowder coating density is the highest grinding efficiency within a certain range, in this regard has accumulated a wealth of empirical data; 4, the orientation of grinding
