Problems solved by technology

[0004] In CCB processing engineering, in order to ensure that the size scale is qualified, it needs to be accurately measured and tested. Most of the current measuring tools use micrometers, etc., and their operation is not fast and convenient enough, which reduces work efficiency.

Embodiment Construction

[0010] The present invention will be further described below in conjunction with the accompanying drawings.

[0011] As shown in Figure 1, the present invention includes a connecting piece 1, and a hexagonal quincunx cross-section cylindrical body pass gauge 2, handle 3, and stop gauge 4; the pass gauge 2 and stop gauge 4 are respectively connected by a connecting piece 1 At both ends of the handle 3, the connector 1 is a cylinder, and the through gauge 2, the handle 3, the stop gauge 4, and the connector 1 are coaxially arranged. One section of the chamfered surface 5 is in the same circle as the handle 3 , and the other end is in the same circle as the connecting piece 1 . The handle 3 is easy for the user to grasp, and at the same time, the chamfered surface 5 makes the transition between the handle 3 and the connecting piece 1 smooth, preventing the user from being scratched and saving materials.

[0012] It should be noted that the through gauge 2, the handle 3, the stop...

Abstract

The present invention relates to a go-no-go gauge for a CCB. The go-no-go gauge comprises connecting pieces, a columnar go gauge, a handle and a no-go gauge, wherein the cross section of the columnar go gauge is in the shape of a hexagonal plum flower. The go gauge and the no-go gauge are respectively connected to the two ends of the handle through one connecting piece. The connecting pieces are cylindrical. The go gauge, the handle, the no-go gauge and the connecting pieces are coaxially arranged. The go-no-go gauge is reasonable in structure, and can effectively defect the size of the CCB. Meanwhile, the go-no-go gauge is simple in operation, convenient and quick, thereby improving the working efficiency.

Description

technical field [0001] The invention relates to the field of measuring instruments, in particular to a go-no-go gauge for CCB. Background technique [0002] The go-no-go gauge is a kind of measuring tool. In actual production, it is very troublesome to measure a large number of products one by one with measuring tools (such as vernier calipers, dial gauges and other graduated measuring tools). We know that qualified products have a measurement range. [0003] All within this range are qualified, so people use the pass gauge and the stop gauge to measure. [0004] In the CCB processing project, in order to ensure the qualified size scale, it needs to be accurately measured and tested. Most of the current measuring tools use micrometers, etc., and the operation is not fast and convenient enough, which reduces the work efficiency. Contents of the invention [0005] The purpose of the present invention is to provide a go-no-go gauge for CCB with reasonable structure and conv...
