Embodiment Construction

[0046] Further set forth by the following specific examples;

[0047] Such as figure 1 As shown, a new type of error-proof fast measuring mechanism includes a driving mechanism 1 , a measuring component 2 and a locking component 3 .

[0048] Such as figure 1 and figure 2 As shown, the linear drive mechanism 1 has a fixed end 11 and a movable end 12 capable of relative displacement with the fixed end 11 in the axial direction.

[0049] Specifically, the linear drive mechanism 1 may be an air cylinder, an oil cylinder or a gas-hydraulic booster cylinder.

[0050] Taking the gas-liquid pressurized cylinder as an example, the fixed end 11 is a cylinder body, and the movable end 12 is a piston.

[0051] The measuring assembly 2 is connected to the fixed end 11 through several sleeves 4 arranged in the axial direction, and the locking assembly 3 is connected to the movable end 12 through a central rod 5 movably sleeved in the sleeves 4 .

[0052] The measuring component 2 and ...

Abstract

The invention belongs to the field of mechanical tools, and relates to a novel mistake-proof rapid measuring mechanism, which comprises a linear driving mechanism, which is provided with a fixed end and a movable end capable of generating relative displacement with the fixed end along the axial direction; the measuring assembly is connected with the fixed end and is provided with a measuring block which is connected with a measuring assembly main body through a first elastic element which is axially arranged, the measuring block is respectively connected with a displacement sensor and a movable mechanism, and the movable mechanism enables the measuring block to have a measuring state of stretching into the groove to be measured and a reset state of moving out of the groove to be measured; and the locking assembly has a locking state for locking the test piece and a loosening state for loosening the test piece, and can generate relative displacement with the measuring assembly along the axial direction under the driving of the movable end. The invention further discloses a groove width measuring method, the measuring assembly is moved to the upper end of the to-be-measured groove of the calibration piece through rapid positioning, the reading is counted to be at the zero position, then the displacement of the upper end of the to-be-measured groove of the to-be-measured piece is read in the same mode, and the groove width of the to-be-measured piece is obtained through calculation. And accurate measurement of the notch is realized.

Description

technical field [0001] The invention belongs to the field of mechanical tooling, and relates to a notch measuring technology, in particular to a novel error-proof fast measuring mechanism and a groove width measuring method. Background technique [0002] Generally, the measurement of the notch can only be measured manually, which is inefficient and has a large error in the measurement result; because of the mechanism of the measuring tool itself, it is difficult to accurately measure the position of some circlip grooves close to other objects. [0003] The Chinese invention patent with the publication number CN213179810U discloses a measuring device for accurately measuring the depth of the deep inner hole groove and the width of the notch, including a height gauge and a measuring mechanism arranged on the measuring claw, and the measuring mechanism includes a clamp , fastening screw, dial, rocker, lead screw guide rail, positioning clamp and lead screw, the clamp is detacha...
