Problems solved by technology
However, since the first distance is the design length and the tolerance is ignored, and the height of the chamfer is very small, the estimation of the height of the chamfer is not accurate
At the same time, the measurement operation of the second distance is cumbersome and the steps are complicated, which is not conducive to reducing the error, further reduces the accuracy of the estimation of the height of the chamfer and the measurement efficiency is low, which is not conducive to improving production efficiency

Embodiment Construction
[0032] The present invention will be further described below with reference to the accompanying drawings.
[0033] like figure 1 and figure 2 As shown, the present embodiment provides a measuring tool for measuring the height of the chamfer in the hole, and the measuring tool for measuring the height of the chamfer in the hole includes: a chamfering top surface clamping block 10, which can be clamped at the top surface of the chamfering 70; The corner bottom surface clamping block 20 can be clamped at the bottom surface of the chamfer 70; the chamfering bottom surface clamping block 20 can slide relative to the chamfering top surface clamping block 10, so that the chamfering bottom surface clamping block 20 slides from the top surface of the chamfer 70 to At the bottom surface of the chamfer 70 ; and the digital display 30 , which can display the sliding distance of the chamfer bottom block 20 relative to the chamfer top block 10 , thereby displaying the height of the chamfe...

The invention provides an in-hole chamfer height measurement gauge, and the gauge comprises a chamfer top surface clamping block which can be clamped at a chamfer top surface; the chamfer bottom surface clamping block can be clamped at the chamfer bottom surface; the chamfering bottom face clamping block can slide relative to the chamfering top face clamping block so that the chamfering bottom face clamping block can slide to the chamfering bottom face from the chamfering top face. And the digital display meter can display the sliding distance of the chamfering bottom surface clamping block relative to the chamfering top surface clamping block, so that the chamfering height is displayed. The in-hole chamfer height measuring gauge can be used for directly measuring the height of the in-hole chamfer and is not influenced by a pressing plate above a cylinder hole. Due to direct measurement, the accuracy of a measurement result is high; and the measurement process is simple, the steps are few, the measurement efficiency can be improved, and the production efficiency can be improved.
Description
technical field [0001] The invention relates to the technical field of machining, in particular to an inspection tool for measuring the height of chamfering in a hole. Background technique [0002] During the machining of the engine cylinder block, it is necessary to make the cylinder bore to install the piston. Chamfering is designed in the cylinder hole, and the main function of the chamfering is to guide the piston to facilitate the assembly of the piston. If the height of the chamfer is too small, the piston will be stuck; if the height of the chamfer is too large, the volume of the combustion chamber will be too small and the swirl flow of the gas in the cylinder will be caused. If the height of the chamfer is too small or too large, it is not conducive to the normal use of the engine. Therefore, it is necessary to measure the height parameter of the chamfer in the cylinder bore. [0003] In order to optimize the production cycle, the machining of the chamfering and t...
