Problems solved by technology
[0004] The purpose of the present invention is to provide a folding lifting and positioning system for a single-arm three-dimensional measuring and marking instrument, which solves the problem in the prior art that it is difficult to ensure its level when using a drill gauge to measure, and achieves the purpose of improving the measurement accuracy of the drill gauge
Aiming at the problem that it is difficult to ensure the level of the existing drill gauge, the present invention proposes a folding lifting and positioning system for a single-arm three-dimensional measuring and marking instrument. By setting a level on the upper surface of the drill gauge, the level is intuitive and accurate. It can accurately judge whether the drill gauge is in a horizontal state, so as to achieve the purpose of improving the measurement accuracy of the drill gauge

Embodiment 1
[0017] like figure 1 and figure 2 The shown foldable lifting and positioning system for a single-arm three-dimensional measuring scriber includes an outer casing 1, an inner sheet 2, a handle 5, a scale bar 3 and an adjusting rod 4 arranged on the upper surface of the outer casing 1, and also includes a The level 6 on the upper surface of the drill bit gauge; the level 6 is arranged near the scale bar 3; the level 6 is a bubble level. In this embodiment, the level 6 is arranged on the casing 1 near the scale bar 3, so that the user can still use the peripheral vision to observe the level 6 when reading the scale, so as to ensure that the read value is within the drill bit gauge. Obtained in a horizontal state to ensure the accuracy of the measurement. During the use of the present invention, firstly rotate the adjusting rod 4 counterclockwise to the end, turn the inner sheet 2 into the outer casing 1, so that the middle diameter of the drill bit gauge is in a maximum state,...

The invention discloses a folding lifting and positioning system for a single-arm three-dimensional measuring and marking instrument, which includes a casing, an inner piece, a handle, a scale bar and an adjusting rod arranged on the upper surface of the casing, and a drill gauge arranged on the drill bit gauge. Surface level. The purpose of the present invention is to provide a folding lifting positioning system for a single-arm three-dimensional measuring and marking instrument, which solves the problem in the prior art that it is difficult to ensure its level when using a drill gauge to measure, and achieves the purpose of improving the measurement accuracy of the drill gauge.
Description
technical field [0001] The invention relates to the field of drill bit gauges, in particular to a foldable lifting and positioning system for a single-arm three-dimensional measuring and scribing instrument. Background technique [0002] The drill bit gauge is a common tool used in the oil and gas drilling industry to measure the diameter of the drill bit, centralizer and other wear parts. It can measure the maximum diameter of the drill bit and centralizer before and after entering the well, and compare the drill bit and centralizer The wear situation in the downhole provides data support for drilling engineers to judge whether to replace the drilling tool assembly. In the process of using the drill bit gauge, insert it into the diameter gauge of the drill bit to be tested and the centralizer in an upright or suspended state, flatten the drill bit gauge with your hand, and turn the adjusting rod clockwise to make the inner piece of the drill bit gauge inward. Turn it out u...
