Description

Technical Field

[0001] This utility model belongs to the relevant technical field, specifically, it relates to a pneumatic measuring instrument for detecting the diameter of a circular arc. Background Technology

[0002] With the rapid development of technology and the progress of manufacturing, there are more and more complex parts. Before some parts can be used, the arc diameter of the parts needs to be measured. Application No. CN202420324869.0 discloses a device for detecting the diameter of an arc using a pneumatic measuring instrument. The diameter measuring body is placed on the arc end face of the part to be tested via a handle. A pneumatic electronic column delivers gas into the gas supply pipe through a gas supply connector. The gas passes through the handle and measuring bracket into the gas supply groove, which then delivers the gas to both sides of the diameter measuring body through an outlet. The gas on both sides of the diameter measuring body acts on the arc of the part. Because the arc diameters of the parts are different, different air pressure changes occur. By observing the pressure of the outflow displayed on the numerical observation column, the arc diameter of the part can be measured. However, for valve body parts, the valve body has arcs of different transition diameters inside its holes. During the testing process, the device needs to be stopped at different heights. Handheld testing is prone to instability, and multiple points such as cross-shaped or star-shaped checks are often required for the same arc position. The testing process is time-consuming and labor-intensive.

[0003] In view of this, this utility model is proposed. Utility Model Content

A support top plate 9 is fixedly provided on the upper end of the electric telescopic rod 8. The support top plate 9 is fixedly connected to the connecting rod 10. A locking sleeve 15 is provided at the end of the connecting rod 10. An air supply pipe 5 is connected to the air supply connector 4 of the pneumatic electronic column 1 and is connected to the connecting column 6 through the connecting end 23. A locking pin 17 is provided at the lower end of the connecting column 6. The locking pin 17 is inserted into the locking sleeve 15. A locking hole 20 is provided on the outer wall of the locking sleeve 15. A locking screw 21 is installed in the locking hole 20 to realize the relative fixed connection between the locking pin 17 and the locking sleeve 15.

[0024] The inner wall of the locking sleeve 15 is provided with an inner sleeve gasket 16, and two tightening surfaces 19 are symmetrically provided on the outer side of the locking pin 17. The tightening surfaces 19 are adapted to the tightening position of the locking screw 21 to improve the tightening stability.

[0025] The lower end of the locking pin 17 is connected to a diameter measuring body 14 by a threaded connection. A sealing groove is provided at the mating position between the diameter measuring body 14 and the lower end face of the locking pin 17. A sealing ring 22 is provided in the sealing groove.

[0027] The gas pipeline 5 is made of flexible hose. Multiple adjustment holes are provided on the outer circumference of the support rotating disk 26. The rotation of the support rotating disk 26 is adjusted by using rods that are compatible with the adjustment holes.

[0029] The working principle of this utility model is as follows:

[0030] Example 1: When measuring the arc diameter of a product, the product is placed on the support rotating disk 26 and fixed with the clamping screw 30. For products that have good stability when placed on the support rotating disk 26, the clamping screw 30 can be omitted depending on actual needs.

The diameter measuring body 14 is inserted into the detection hole and cooperates with the pneumatic electronic column 1 to measure the arc diameter. The detection process and principle are the same as those of the existing patent: CN202420324869.0 A device for measuring the arc diameter using a pneumatic measuring instrument. In order to expand the detection range of the same arc position, multi-point detection can be performed in different diameter directions.

[0031] Example 2: After the detection of a position is completed, the locking rod 28 is pulled out from the locking ear plate 27, the support rotating disk 26 is rotated to a certain angle, and then the locking rod 28 is used to fix the relative position to perform multi-point detection at the same diameter position. The detection process has good stability.

[0032] The pneumatic electronic column 1 of this utility model is equipped with a height-adjustable mounting locking sleeve 15, which is used to fix the locking pin 17 above the diameter measuring body 14, so as to achieve effective stopping of the detection position during the detection process. The detection process does not require long-term hand operation, reducing the labor intensity of the operator. The diameter measuring body 14 is provided with a support base 24 and a support rotating disk 26. The product being measured is on the support rotating disk 26, and the support rotating disk 26 can rotate relative to the support base 24. The rotation angle can be limited by the cooperation of the locking ear plate 27, the locking rod 28, and the limiting hole 25, so as to realize multi-point detection.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
