High-precision inner conical surface taper rapid detection tool

Abstract

The invention discloses a high-precision inner conical surface taper rapid detection tool which comprises a dial indicator, a detection arm and a support, the support comprises a support body, a detection arm installation cushion block and a dial indicator installation block, and the detection arm installation cushion block and the dial indicator installation block are arranged on the support body. The support body is L-shaped; The detection arm installation cushion block and the dial indicator installation block are respectively installed at the lower part and the upper part of the same sideof the support body, the detection arm installation cushion block is provided with a bolt hole, and the dial indicator installation block is provided with a through hole for installing a dial indicator; the detection arm comprises a detection rod and a push rod which are equal in length and are perpendicular to each other, a probe is arranged at the free end of the detection rod, and the free endof the push rod is a measuring head contact end and used for making contact with a measuring head of the dial indicator. The tool is easy to operate, visual in data display and free of skill requirements for operators, the operators detect the parts before the parts are taken off the machine, unqualified products can be found in time, and the paths of missing detection and missing placement of theunqualified products are eradicated.

Description

technical field [0001] The invention relates to a high-precision tool for quickly detecting the taper of an inner taper surface. Background technique [0002] The connection between the pipeline system usually adopts the connection scheme of connecting nozzle and ball head. There are two ways to detect the taper size of the inner cone surface of the connecting nozzle: one is to make a special angle gauge for light transmission detection, and judge according to the light transmittance. Whether it is qualified; the other is to use a three-coordinate measuring machine to detect. These two measurement methods mainly have the following problems: [0003] 1. Low detection accuracy: the use of special gauges is used to determine whether the product is qualified or not based on the light transmittance. When the taper accuracy is high, the light transmission difference of the gauge is not obvious, and it is impossible to judge whether it is qualified by human eyes. [0004] 2. Low ...

Problems solved by technology

[0003] 1. Low detection accuracy: the use of special gauges is based on the light transmittance to determine whether it is qualified. When the taper accuracy is high, the difference in light transmission of the gauge is not obvious, and it is impossible to judge whether it is qualified by human eyes

[0004] 2. Low detection efficiency: Use a three-coordinate measuring machine for detection. If the measurement is unqualified, it needs to be sent for inspection after adjusting the parameters until it is qualified; affected by tool wear, subsequent production and processing to a certain amount still need to be sent for inspection; in frequent During the inspection process, the operators and equipment are in a waiting state, which greatly wastes manpower and equipment resources. Especially if unqualified products are found during the random inspection process, production must be stopped for reverse inspection or all parts in this random inspection section will be sent for inspection and testing. , seriously affecting production efficiency
