Abstract

The invention provides a blank locating detection device which comprises a base, a spring, a locating block and a bolt; a first hole perforating axially and a second hole perforating radially are formed in the base; the first hole comprises a mounting hole part located at the upper part and a first air hole part located at the lower part; the spring is fixed in the first air hole part; the locating block is slidingly matched with the mounting hole part; a gap is formed between the locating block and the mounting hole part; the locating block is provided with a third hole perforating radially; the bolt is inserted into the second hole and is fixed to the base; a cavity is formed between the bolt and the third hole; and a gap is formed between the locating block and the bottom of the mounting hole part under the action of the spring. During working, the locating block moves downwards to be fitted with the bottom of the mounting hole part under the action of a clamping force, by this time, detection gas can not be discharged outwards because an external leakage passage of the detection gas is closed, so that the purpose of airtightness detection of the locating surface of a blank is achieved. The blank locating detection device is high in structural strength, high in reliability and long in service life, a clamping locating process is stable, and the impact on a workpiece is reduced.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a blank positioning detection device. Background technique [0002] In the process of machining, the workpiece needs to be positioned to ensure its correct position. For example, when the blank positioning surface is used to position the blank workpiece on the machine tool, the air tightness test of the blank positioning surface is usually required to ensure that the workpiece is positioned in place. However, due to the large dimensional tolerance and unevenness of the surface of the blank workpiece, it is often difficult to perform air-tightness testing on the surface in the traditional way. [0003] Most of the current air tightness testing of the blank positioning surface is to install an elastic pin on a fixed positioning block, and close the air passage by pressing down the elastic pin, so as to achieve the purpose of air tightness testing. The disadvantage of this met...
