Problems solved by technology

[0003] The fiber optic ferrule diamond drill has four symmetrical blades, and the concentricity between the tip and the tool holder is required to be 0.01mm. If the clamping concentricity is not good or the indexing is not accurate when the four sides are rotated, the tip of the tool will be eccentric.
[0004] Traditional processing uses hand tools for turning stone arms for jewelry processing. The clamping accuracy is 0.02-0.05mm low, and the repeated positioning of quarters is not accurate.

Abstract

The invention discloses a grinding fixture for diamond drilling tools. The grinding fixture comprises a spring chuck, a stepper motor, a connecting rod, an arc-shaped slide rail, a slider cylinder, a feed screw and a slide platform. The spring chuck for clamping a diamond drilling tool to be ground is fixed to one end of the stepper motor of a driving device, the stepper motor is connected to the lower side of the arc-shaped slide rail by the connecting rod in such a manner that the head end of the spring chuck is downwardly and obliquely arranged, the arc-shaped slide rail is mounted on the lower surface of an extending end of a cantilever of the slider cylinder, the feed screw is mounted on the upper side of the slider cylinder, the feed screw and the slider cylinder are matched with each other and can adjust the height of the diamond drilling tool to be ground, and the slider cylinder is fixed onto the slide platform. The grinding fixture for the diamond drilling tools has the advantages that the concentricity of four blades of the diamond drilling tool is greatly improved, the quality of a product is improved, and the grinding fixture is simple in operation and high in machining production efficiency.

Description

technical field [0001] The invention belongs to the technical field of machining fixtures, in particular to a diamond drill grinding fixture. Background technique [0002] The diamond drill bit for optical fiber ferrule is a kind of superhard tool used to process the fast docking ceramic plug of optical fiber cable for communication. With the continuous progress of optical fiber communication technology in recent years, the application of optical fiber fast docking plug is becoming more and more extensive, and the demand continues to increase. The diamond drill bit for optical fiber ferrule is one of the important processing tools, and its performance and cost are directly related to the cost of optical fiber fast connectors. However, the processing technology of diamond drills has been blocked by developed countries for many years, and the use of products has always been dependent on imports. [0003] The fiber optic ferrule diamond drill has four symmetrical blades, and t...
