Problems solved by technology

The debugging of the bearing tester requires professional debugging. The debugging time of the bearing tester is relatively long, and it needs to be adjusted by marking and repeated comparison. Since the three measuring feet are fixed, there will be measurement errors when measuring the inner diameter.

Embodiment Construction

[0011] The present invention will be further described below in conjunction with accompanying drawing:

[0012] As shown in the figure, this gas-electric detection device for quickly detecting the inner diameter of pores mainly includes a detection device body, which is provided with a measuring platform measuring column 1, and an air hole 3 is provided on the measuring platform measuring column 1, and the air hole 3 The air pipe 4 communicates with the gas electricity meter 5, and the gas electricity meter 5 is provided with a display screen 6. The outer diameter of the measuring platform measuring column 1 is matched with the inner diameter ring gauge 2 or the product to be tested 7 so that it can be set on the measuring platform measuring column 1, and the air hole 3 runs through the measuring platform measuring column 1 along the diameter direction of the measuring platform. Column 1.

[0013] When measuring, first put the inner diameter ring gauge 2 on the measuring plat...

Abstract

The invention relates to an air-electric detecting device for quickly detecting the inner diameters of holes. The air-electric detecting device mainly comprises a detecting device body; the detectingdevice body is provided with a detection platform measuring column; an air hole is formed in the test platform measuring column; the air hole is communicated with an air electric gauge through an airpipe; the outer diameter of the detection platform measuring column can be sized to match an inner diameter ring gauge or a product to be tested, so that the inner diameter ring gauge or the product to be tested can sleeve the detection platform measuring column; and the air hole extends through the detection platform measuring column along the diameter direction of the detection platform measuring column in a through manner. With the device of the invention adopted, professionals for debugging are not required; the debugging time of a testing tool is short; the debugging time of the detectingdevice is shortened; the inner diameter of the product is in air-tight contact with the circumference of the column, and therefore, detection precision is high, and errors are small; and a diameter dimension can be directly measured; inner diameter detection is changed from mechanical three-point contact to circumferential airtight contact, and therefore, detection errors are reduced.

Description

technical field [0001] The invention relates to the structure of an inner diameter detection device, in particular to a gas-electric detection device for quickly detecting the inner diameter of pores. Background technique [0002] The inner diameter of hole products is usually calibrated with an inner diameter bearing inspection instrument equipped with a lever gear comparator, inner diameter ring gauge, and the inner diameter size to be measured is adjusted by adjusting the position of the three measuring feet. The inner diameter of the product to be tested is mechanically contacted and converted with the three measuring feet , the data is read on the lever gear comparator. The debugging of the bearing tester requires professional debugging. The debugging time of the bearing tester is relatively long, and it needs to be adjusted by marking and repeated comparison. Since the three measuring feet are fixed, there will be measurement errors when measuring the inner diameter. ...
