Abstract

The invention discloses a mechanical part hole pitch tolerance measuring test tool convenient to use. The mechanical part hole pitch tolerance measuring test tool comprises a positioning plate. A sliding groove is formed in the upper surface of the positioning plate. A sliding block is arranged inside the sliding groove. A brake switch is arranged on the sliding block. One end of the brake switch extends into a strip-shaped through hole formed in the front face of the positioning plate. A dial gauge is arranged on the lower side of the strip-shaped through hole. A sliding detection column is arranged on the sliding block. A fixed detection column is arranged on one side of the sliding groove. A handle is arranged in the middle of the lower surface of the positioning plate. The mechanical part hole pitch tolerance measuring test tool convenient to use is convenient to operate, high in measuring efficiency, good in adaptability to the distance between two holes in various to-be-detected components, and capable of conveniently detecting whether the tolerance of holes in various to-be-detected components is qualified or not, workers can complete overall self-inspection at any time, and the production efficiency and the production quality are improved.

Example Embodiment

[0014] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0015] see Figure 1-3 , the present invention provides a technical solution: an easy-to-use measuring tool for measuring the hole distance tolerance of mechanical parts, comprising a positioning plate 1, the upper surface of the positioning plate 1 is provided with a chute 2, and the interior of the chute 2 is provided with a slider 3. The slider 3 is provided with a brake switch 4, one end of the brake switch 4 extends into the bar-shaped through hole 5 provided on the front of the positioning plate 1, and the lower side of the bar-shaped through hole 5 is provided with a scale 6 , the brake switch 4 is circular, and the bottom of the brake switch 4 is provided with a fingertip 401, the fingertip 401 is triangular, and the fingertip 401 is provided with a contrast line 402, the contrast line 402 and the scale 6 The tick marks are vertically parallel to each other.
[0016] The sliding block 3 is provided with a sliding detection column 7, one side of the chute 2 is provided with a fixed detection column 8, and a handle 9 is provided in the middle of the lower surface of the positioning plate 1, the handle 9 is arc-shaped, and the outer surface of the handle 9 is provided With non-slip threads.
[0017] When using this inspection tool for detection, the sliding detection column 7 slides on the chute 2 through the slider 3, so as to adjust the distance between the sliding detection column 7 and the fixed detection column 8, and put the brake switch 4 on the fingertip 401. The comparison line 402 is aligned with the specified scale line on the scale table 6, and the length value of the specified scale line is the same as the distance between the two holes of the workpiece to be tested, and then the sliding detection column 7 is fixed by the brake switch 4, and then the sliding detection column 7 is fixed. The center of the column 7 and the fixed detection column 8 are aligned with the center of the two holes of the workpiece and inserted into the two holes of the workpiece to be tested at the same time. If they cannot be inserted, it means that the hole distance and position are unqualified. Qualified, the inspector can hold the handle 9 provided in the middle of the lower surface of the inspection tool positioning plate 1 for inspection. The operation is convenient, the measurement efficiency is high, and the distance between the two holes of various parts to be inspected is well adapted. It can easily detect whether the tolerances of various parts to be inspected are qualified, and workers can self-inspect all of them at any time, which improves production efficiency and production quality. The operation is simple and convenient, and each piece can be inspected to improve production Efficiency and quality, the inspection column should be regularly inspected for tolerances, and those that reach the wear limit should be eliminated in time to prevent inspection errors.
[0018] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, and substitutions can be made in these embodiments without departing from the principle and spirit of the invention and modifications, the scope of the invention is defined by the appended claims and their equivalents.
