Embodiment 1

[0019] A 7:24 tool taper shank comprehensive detection device, which consists of: a base 2 with a taper hole 1, one side of the base 2 is equipped with a power-up sensor head 3 and a power-down sensor head 4, the The power-up sensor head 3 and the power-down sensor head 4 are connected to the comparator 5, and the upper end side of the base 1 is connected to the ball probe dial indicator 7 through the support 6, and the ball probe percentage indicator The meter 7 contacts the standard rod 8, the standard rod 8 contacts the lever swing meter 9, the upper end of the base 1 is equipped with an outer circle dial indicator 10 and a dial indicator 11, and the lower end of the base 1 is installed on one side. Tail hole jump, size dial indicator 12 are arranged, and cone length dial indicator 13 is equipped with on the other side of described pedestal lower end.

[0020] In the 7:24 tool taper shank comprehensive detection device, the outer circle dial indicator is installed at a posi...

Embodiment 2

[0022] A 7:24 tool taper shank comprehensive detection method. On a precisely processed base, the inductive probe for detecting the taper angle and outer cone roundness of the taper shank is fixed, the inductive probe is connected with the inductance comparator, and the measurement Indicators of other sizes and precisions are fixed by the mechanism, and then through the mechanism, the electrical probe and each indicator probe are in contact with the attached standard bar measurement surface, and the pointers of the comparator and each indicator are aligned to zero, and then the tested tool Put in the taper handle of the tool shank, and measure the taper angle error by reading the deviation of the inductance comparator; rotate the taper handle to measure the roundness of the probe through the pointer fluctuation range on the comparator; adjust other probes to make them match the taper handle The measured surface is in contact, and the value of the pointer’s deviation from the ze...

Embodiment 3

[0024] According to the 7:24 tool taper shank comprehensive detection method and device described in Embodiment 1, two adjustable upper and lower electrical probes are installed on a base with a 7:24 taper hole for use by a comparator. Measure the taper angle error and roundness of the 7:24 tool handle after zero calibration with a standard rod, and the accuracy can reach 0.1 μm; pass the lever swing meter, ball probe dial indicator, and dial indicator with a standard rod for zero calibration. 3.2±0.1, 11.1±0.1, 19.1 0 -0.1 , ∮72.3±0.05 (SK40 handle, or SK50 handle ∮107.25±0.05) four important dimensions; through the outer circle dial indicator with a standard rod to zero, the test standard stipulates the flange outer circle size and runout; through the cone length percentage The test standard stipulates the length and end face runout of the taper shank after zero calibration with a standard rod; the test standard specifies the diameter size and runout of the taper shank pull...

Abstract

The invention provides a comprehensive detection method and device of a tool tapered handle (7:24). The existing detection method adopts a plurality of detection devices for a plurality of detection by items and is applicable to step-by-step low-efficiency small-scale production of single piece, but the detection efficiency is affected due to a large quantity of detection items and detection devices in efficient mass production and final finished-product detection. The device comprises a base (2) with a tapered hole (1); one side of the base is equipped with an upper inductive measuring head (3) and a lower inductive measuring head (4); the upper inductive measuring head and the lower inductive measuring head are connected with a comparator (5); one side of the upper end of the base is connected with a spherical measuring head dial indicator (7) through a bearing (6); the spherical measuring head dial indicator is contacted with a standard bar (8); the standard bar is contacted with a lever swing meter (9); and the upper end of the base is equipped with an excircle dial indicator (10) and a dial indicator (11), one side of the lower end of the base is equipped with a tail hole jumping and size dial indicator (12), and the other side of the lower end of the base is equipped with a tapered length dial indicator (13). The invention is applied to detection of the tool tapered handle (7:24).

Description

Technical field: [0001] The invention relates to a comprehensive measurement method and device for measuring the accuracy and size of the handle of a CNC machine tool automatic tool change tool handle produced according to the international ISO7388 / 1-1983 (E) or the national standard GB10944-89, and specifically relates to a 7 : 24 tool taper shank comprehensive detection method and device. Background technique: [0002] According to the international ISO7388 / 1-1983 (E) or national standard GB10944-89 (equivalent to German DIN79871 / 1-1995) standards, the shank accuracy and size inspection items of the CNC machine tool automatic tool change tool holder have many inspection items and high accuracy requirements. . Existing detection methods use multiple sets of detection devices and multiple detections per item, which is suitable for low-efficiency single-piece and small-batch production in division of labor steps. However, due to the large number of detection items and the de...
