Cutting tool angle measuring instrument

Abstract

The invention relates to a cutting tool angle measuring instrument comprising a rough adjusting pedestal, and a precise measuring apparatus and a cutting tool fixing apparatus arranged above the rough adjusting pedestal. The precise measuring apparatus has a structure that: a positioning seat is arranged on the upper surface of the rough adjusting pedestal; a meter seat is arranged in the hollow cavity of the positioning seat; a horizontal threaded rough hole is arranged in the middle of the meter seat; a lead-screw is coupled with the thread of the meter seat; two ends of the lead-screw are positioned on the positioning seat; one end of the lead-screw is connected with a feeding handle; a meter rack is arranged on the upper surface of the meter seat; a dial indicator I is vertically arranged on an end of the meter rack; the top point of the dial indicator I contacts the surface of a cutting tool requiring measuring; an adjusting rod is connected to a side of the meter seat; an end face of the adjusting rod extends out of the positioning seat, and contacts a top point of a dial indicator II horizontally arranged on the upper surface of the rough adjusting pedestal. The cutting tool angle measuring instrument is advantaged in simple structure and convenient operation. With the instrument, the geometrical angle of the cutting tool can be rapidly and accurately measured.

Description

technical field [0001] The invention relates to a tool angle measuring instrument, which is an instrument for measuring the geometric angle of a tool. Background technique [0002] In the past, simple angle measurement devices were mostly used in tool geometric angle measurement methods. The structure of this type of device is similar to that of an angle ruler. Its obvious disadvantages are: 1. The positioning reference is not good; 2. The measurer needs to have high visual judgment ability ; 3. The measurement data is inaccurate. At present, some enterprises in the world have developed an optical device. This type of device uses optical principles to measure data, transmits it to the control system through sensors, and realizes angle value measurement through the function of the software itself. The disadvantages are: 1. Operating software It is more complicated, and there are many factors to be considered; 2. The operator of the measuring instrument needs strict professio...

At present, some enterprises in the world have developed an optical device. This type of device uses optical principles to measure data, transmits it to the control system through sensors, and realizes angle value measurement through the function of the software itself. The disadvantages are: 1. Operating software It is more complicated, and there are many factors to be considered; 2. The operator of the measuring instrument needs strict professional training; 3. Due to the limitation of the clamping method, the measurement range is limited, that is, some tools cannot be measured; 4. The measurement takes a long time ;5. The price of this kind of equipment is extremely expensive, and ordinary enterprises cannot afford to buy it at all.
